2019-01-01T01:21:21 < specing> Are we supposed to measure internal voltage reference and use that to calculate real ADC value of the temperature sensor? Or is using the ST-provided process calibration data enough? My problem is that the chip is reporting 29'C - 30'C while the room I am in is somewhere between 20-23'C
2019-01-01T01:21:44 < specing> or is the +5'C due to the cortex-m0 busy looping instead of sleeping?
2019-01-01T01:22:00 < specing> could be as high as +10'C error, even
2019-01-01T01:28:54 < fenugrec> specing, a measurement done immediately after powering up (assuming chip was left off long enough to cool to room temperature) should give a baseline before the die heats up
2019-01-01T01:30:20 < specing> right
2019-01-01T01:30:54 < specing> baseline is 26'C it seams
2019-01-01T01:30:59 < specing> that is more like it
2019-01-01T01:31:30 < fenugrec> it probably needs more than 2 minutes to equalize to room temp though
2019-01-01T01:31:31 < specing> unfortunately I have no good standalone thermometer here to measure real temperature more closely
2019-01-01T01:31:39 < specing> it was off for 3h
2019-01-01T01:31:45 < fenugrec> oh ok
2019-01-01T01:32:03 < specing> it is already at 28'C
2019-01-01T01:33:07 < fenugrec> no idea what you're doing, but you might consider an external thermistor / temp transducer for more better accuracy
2019-01-01T01:33:36 < specing> ah I was just playing with the ADC and built-in sensor
2019-01-01T01:33:46 < specing> (the latter as a way to test the former)
2019-01-01T01:34:27 < specing> ST put some mems gyro chip on the board that also has a temp sensor (at 1'C resolution), I guess I'll try and get that working
2019-01-01T01:35:07 < fenugrec> I'd expect it to read hotter than ambient pretty fast : RM says "sensor can be used to measure the junction temperature of the device", so it's likely right inside the die. 
2019-01-01T01:35:53 < specing> I guess
2019-01-01T01:36:17 < specing> perhaps it was put there so software would know when the chip is on fire
2019-01-01T01:55:29 < kakimir> me is in year 2019
2019-01-01T01:55:37 < kakimir> specing is too

2019-01-01T01:56:14 < specing> WITH NO DEAL
2019-01-01T01:56:22 < kakimir> yes
2019-01-01T01:56:26 < invzim> specing: the temp stuff is internal ic temp, not ambient
2019-01-01T01:57:19 < kakimir> they do not concur if year 2018 is to be changed to year 2019
2019-01-01T01:59:21 < PaulFertser> specing: with stm32l152 I had to measure internal voltage reference, yes.
2019-01-01T01:59:57 < PaulFertser> specing: return (110 - 25) * (meas_int_adc(ADC_Channel_TempSensor)*meas_vref()/300 - *(uint16_t*)0x1FF8007A) / (*(uint16_t*)0x1FF8007E - *(uint16_t*)0x1FF8007A) + 25;
2019-01-01T02:02:47 < specing> PaulFertser: did the datasheet say so? Because the datasheet does not explicitly say so in my case
2019-01-01T02:03:00 < aandrew> specing: what do you get when you measure the 3.3V rail with a meter and with the ADC usiing internal reference
2019-01-01T02:03:21 < specing> aandrew: I have not tried doing that, yet
2019-01-01T02:07:27 < invzim> this is what I do on f401:
2019-01-01T02:07:28 < invzim> VDDAmillivolts=3300 * (*((unsigned short*) VREFINT_CAL_ADDR_STM32F401));
2019-01-01T02:07:28 < invzim> VDDAmillivolts/=adcReading[AD_VREFINT];
2019-01-01T02:07:29 < invzim> suma2v3+=adcReading[AD_2V3] * VDDAmillivolts / 4095;

2019-01-01T12:25:56 < DisruptiveNL> Hi!
2019-01-01T12:26:25 < DisruptiveNL> Does anyone know if there is a shield for a Nucleo (STM32) with MMC/SD??
2019-01-01T12:30:21 < dongs> https://www.st.com/en/evaluation-tools/stm32-nucleo-expansion-boards.html?querycriteria=productId=SC1971
2019-01-01T12:30:36 < dongs> this is a list of all existing boards.
2019-01-01T12:30:50 < dongs> i doubt something "wiht only sd" exists as y ou can get a breakout for $1 and hook it up with some jumper wires

2019-01-01T12:33:42 < DisruptiveNL> I am busy to make a board L476RG with MEMS (IKS01Ax) and BLE (Bluetooth = X-NUCLEO-IDB05A1) for GPS (10Hz) and MEMS/SD. I want to get Sensor Fusion working for localization. 
2019-01-01T12:34:03 < DisruptiveNL> My base board is the Nucleo stm32l476rg
2019-01-01T12:35:45 < dongs> does that have sdio
2019-01-01T12:35:49 < zyp> isn't the point of nucleo to be compatible with arduino shields?
2019-01-01T12:35:56 < zyp> although those wouldn't have SDIO
2019-01-01T12:35:57 < dongs> ah it has the new one
2019-01-01T12:36:03 < dongs> sdmmc interface
2019-01-01T12:36:32 < zyp> dongs, is there a new peripheral different from the old SDIO one?
2019-01-01T12:36:36 < dongs> i don't see why you can't just jumperwire the 4 or so pins needed for teh card
2019-01-01T12:36:37 < dongs> yeah
2019-01-01T12:36:40 < dongs> called 'sdmmc'
2019-01-01T12:36:56 < zyp> how do they differ in features?
2019-01-01T12:36:58 < dongs> https://www.st.com/content/ccc/resource/training/technical/product_training/0d/2d/cc/55/55/a6/42/12/STM32L4_Peripheral_SDMMC.pdf/files/STM32L4_Peripheral_SDMMC.pdf/jcr:content/translations/en.STM32L4_Peripheral_SDMMC.pdf
2019-01-01T12:37:04 < dongs> i think its only or L4
2019-01-01T12:37:06 < dongs> or=for
2019-01-01T12:37:12 < DisruptiveNL> ah oke
2019-01-01T12:38:39 < zyp> I guess it fixes the errata that only let the old periph run at clock/2
2019-01-01T12:38:55 < zyp> i.e. 24 MHz unless you overclocked the 48MHz USB clock to 96 MHz
2019-01-01T12:39:20 < zyp> apart from that I don't see any obvious improvements
2019-01-01T12:39:22 < zyp> at a glance
2019-01-01T12:39:53 < dongs> i think old sdio doesnt support 8bit width?
2019-01-01T12:39:57 < dongs> could be wrong tho
2019-01-01T12:40:13 < dongs> i only used it on 64pin packages
2019-01-01T12:40:57 < dongs> oh it does have 8bit.
2019-01-01T12:41:00 < zyp> pretty sure it did
2019-01-01T12:41:10 < dongs> yeah i just looked at rm0090 and it does
2019-01-01T12:41:14 < zyp> only relevant for emmc though
2019-01-01T12:51:14 < DisruptiveNL> I am thinking about setting up a Open Source MIT project for doing localization with MEMS and GPS (SensorFusion) and (Extended)Kalman
2019-01-01T12:52:52 < DisruptiveNL> Do you think this would be something?
2019-01-01T12:53:04 < zyp> that's probably never been done before
2019-01-01T12:53:47 < DisruptiveNL> I am converting all the (Extended) Kalman stuff to C (ANSI 89) and I am testing the matrix culculations (inverting is the most complex)
2019-01-01T12:55:05 < DisruptiveNL> But it is complex and maybe with more we can accomplish things
2019-01-01T12:55:10 < zyp> what's the point of dicking around with a 30 year old C standard?
2019-01-01T12:55:28 < DisruptiveNL> Because I want to use a RTOS
2019-01-01T12:55:57 < zyp> I don't see how that follows
2019-01-01T12:55:58 < DisruptiveNL> And I have been working with Nuttx for some time now on STM32 and this really works!
2019-01-01T12:56:08 < zyp> are there any RTOSes that don't work with C11?
2019-01-01T12:56:48 < DisruptiveNL> Yes I tried them all I think for about 3 years now
2019-01-01T12:57:02 < DisruptiveNL> ChibiOS is great! But the license has been changed
2019-01-01T12:57:15 < DisruptiveNL> FreeRTOS... no...
2019-01-01T12:57:39 < DisruptiveNL> Nuttx! WOW!

2019-01-01T13:22:07 < Steffanx> Make it os indepedent. If you use nuttx only jpa- might use it.
2019-01-01T13:22:35 < jpa-> not even me, because the only project i use nuttx for seems unlikely to need it
2019-01-01T13:22:51 < jpa-> but i'd be very surprised if the PX4 project doesn't already have a sensor fusion + location stuff for nuttx
2019-01-01T13:31:11 < DisruptiveNL> Yes maybe you are right!
2019-01-01T13:32:08 < DisruptiveNL> The logic on ¨shield¨ which can be used as a shield of some sort...

2019-01-01T14:54:29 < DisruptiveNL> Oke ChibiOS is pure the license. I did make some cool stuff with it.
2019-01-01T14:54:45 < PaulFertser> I would expect there would be some more obvious way to detect the "rotor stuck" condition though.
2019-01-01T14:55:07 < DisruptiveNL> FreeRTOS is bulky and not ¨handy¨ in coding and setting up a project. 
2019-01-01T14:55:18 < jpa-> next try mbed?
2019-01-01T14:56:02 < DisruptiveNL> Nuttx is maybe a bit ¨bigger¨ although I think this is minimal and once you get the hang of it, it is very strong in implementing drivers from datasheets, MCU-s, etc
2019-01-01T14:56:41 < DisruptiveNL> Mbed is more empty ..... It looks oke but its like Microsoft... if you get deeper you will find out its not there at all...
2019-01-01T14:58:54 < DisruptiveNL> Nuttx als has a very cool BSD license
2019-01-01T14:59:41 < DisruptiveNL> And the support on the Google group and IRC channel is also strong
2019-01-01T15:00:05 < DisruptiveNL> There is a ¨kernel¨ who is very strict, but I think thats good!
2019-01-01T15:05:02 < Steffanx> Are there other russian curse words? All i ever hear is cyke blyat.

2019-01-01T15:39:21 < PaulFertser> Cracki: kurwa is polish, I do not think he said that, he might be from ukrain but they do not normally say kurwa either.
2019-01-01T15:40:12 < PaulFertser> Cracki: the rotor is mechanically stuck so it should be kinda obvious by load current (or overcurrent protection kicking in) or something like that.
2019-01-01T15:41:19 < PaulFertser> He didn't even tried measuring the voltage across those resistors when the motor is trying to move.
2019-01-01T15:43:47 < PaulFertser> I haven't looked closely at the schematics but it's visible there on the door including the three resistors and he was measuring their resistances.
2019-01-01T15:45:05 < PaulFertser> Steffanx: other popular words are "khooy" (penis) and "peezduh" (vagina) and the derivatives.

2019-01-01T15:50:05 < invzim> same setup, but with rigol dp831
2019-01-01T15:50:56 < invzim> this is the root cause of some crap that I've been troubleshooting/engineering around for 5-6 months :(
2019-01-01T15:52:36 < invzim> I should dig out another atx supply to see if the problem is as severe, or if the psu is just plain bad
2019-01-01T15:52:52 < invzim> it's the 5v rail
2019-01-01T15:53:33 < invzim> the effect is really bad video noise on a few old jamma games
2019-01-01T15:55:32 < invzim> I got a nice dp831 psu, but other people do not - this came about when doing video processing of these signals
2019-01-01T15:56:07 < invzim> so was thinking maybe making a supply cleaner thingie, if it's feasible
2019-01-01T16:03:51 < invzim> I trust it, 1.56kHz on primary
2019-01-01T16:05:53 < invzim> will do some more testing, could very well be the load isn't static
2019-01-01T16:13:34 < fenugrec> invzim, do you have a minimum load on that psu
2019-01-01T16:13:55 < fenugrec> on the "right" rail
2019-01-01T16:14:28 < invzim> not that I'm aware of, atx psu's should work fine <4A
2019-01-01T16:15:12 < fenugrec> hmm probably but it might want a few 100mA but on a certain rail for regulation to work
2019-01-01T16:16:10 < fenugrec> I'd try another one before opening that one up 
2019-01-01T16:16:17 < fenugrec> another *psu
2019-01-01T16:19:14 < invzim> I actually got a fancy dc load, so can try that one too to get a base reading

2019-01-01T19:32:38 < Thorn> how do you generate threaded code in a compiler? you need to know all the subroutine addresses in the interpreter in advance
2019-01-01T19:34:07 < Thorn> or is threaded code only usable for immediate execution in the same program where it was generated?
2019-01-01T19:34:33 < Thorn> or should I do some kind of relocation when loading
2019-01-01T19:39:50 < Thorn> but this "relocation" would essentially mean compiling bytecode into threaded code
2019-01-01T19:46:20 < mawk> there is some kind of relocation
2019-01-01T19:46:24 < mawk> at least on x86
2019-01-01T19:46:32 < mawk> using the thread local registers
2019-01-01T19:46:45 < mawk> well the thread local pointer that's in the %gs register I believe
2019-01-01T19:46:46 < mawk> %fs or %gs

2019-01-01T20:16:31 < aandrew> I'm having understanding this wikipedia article
2019-01-01T20:17:23 < englishman> i think you a word
2019-01-01T20:17:43 < mawk> yeah it's not wonderfully written aandrew 
2019-01-01T20:18:03 < mawk> it just means that you compile the opcodes to machine code only once, then your program is only a suite of call instructions
2019-01-01T20:18:15 < mawk> depending on the type of threading
2019-01-01T20:18:20 < mawk> you could have a bytecode decoding step

2019-01-01T20:21:45 < mawk> so Thorn I think you have the choice depending on the complexity of the subroutine call
2019-01-01T20:22:11 < mawk> I think in any case you can compile in situ, that's a constant time, doesn't add to complexity
2019-01-01T20:22:16 < mawk> for optimization you can cache that
2019-01-01T20:22:47 < jpa-> Thorn: all of the options you are mention are possible, it depends totally on the implementation
2019-01-01T20:23:08 < Thorn> subroutines here mainly represent primitive operations, equivalent to machine instructions (pop, push, add, etc)
2019-01-01T20:24:14 < aandrew> but why
2019-01-01T20:24:23 < aandrew> why call add() instead of execute add?

2019-01-01T20:28:04 < Thorn> add() is likely pop r0; pop r1; add r0,r0,r1; push r0
2019-01-01T20:29:56 < jpa-> on arm, a direct bytecode interpreter is probably easier and faster than trying to make it into subroutine calls

2019-01-01T20:32:26 < mawk> why jpa- ?
2019-01-01T20:32:59 < aandrew> yeah I was going to say the same, I don't understand the benefit of threaded code
2019-01-01T20:33:01 < jpa-> pawn's bytecode interpreter for thumb2 is basically a block of code for each operation, and each block ends with macro NEXT() that does    ldr r11, [r4], #4  to load next opcode,  ldr pc, [r14, r11, LSL #2]  to load handler address from array and jump to it; no return from subroutine needed
2019-01-01T20:33:23 < aandrew> why would you be popping and pushing anything, r0 and r1 would have been loaded and add is a single isntruction
2019-01-01T20:33:57 < Thorn> jpa-: this is indirect threaded code
2019-01-01T20:34:26 < Thorn> if I understood correctly
2019-01-01T20:34:38 < jpa-> Thorn: yeah
2019-01-01T20:35:09 < jpa-> hmm no
2019-01-01T20:35:21 < jpa-> i'd say it is more like "direct threading" in that wikipedia article
2019-01-01T20:35:37 < jpa-> hmm no
2019-01-01T20:35:48 < jpa-> i'd say it is just an efficient way to do a bytecode interpreter
2019-01-01T20:36:02 < jpa-> because the actual program doesn't have any real addresses, it has just index to a table that has the addresses
2019-01-01T20:36:31 < jpa-> in pawn, the opcode function pointer table is stored in r14, and r11 will get an index to that table (the index = bytecode instruction)
2019-01-01T20:37:21 < jpa-> ah, that's called token threading

2019-01-01T20:40:54 < jpa-> Thorn: you could also force the addresses of the subroutines to be constant, but that would waste some flash if you want to reserve space for expansion

2019-01-01T21:00:35 < PaulFertser> specing: I think it's kinda obvious that if the ADC is using Vcc as the Vref then you just have to take that into account. Of course it depends on how exactly the temperature sensor is implemented. That line of code was written several years ago so I do not remember the exact reasoning but I was getting nice results with it.

2019-01-01T21:15:55 < PaulFertser> Yes, where one uses measurement units that actually make sense as a system.

2019-01-01T21:17:08 < bitmask> hah
2019-01-01T21:17:17 < bitmask> wouldn't SI for temp be kelvin?

2019-01-01T21:18:29 < Steffanx> You still didnt fix the logo thing bitmask :P
2019-01-01T21:19:19 < PaulFertser> Yes, primary is Kelvin, degree Celsius derived. But they're trivial to convert and also when you need some \delta T it's not required.
2019-01-01T21:19:24 < bitmask> the mirror? its not really broken, its just that the silkscreen one is on the back of the pcb so its mirrored, I think i want to switch to it anyway but its not like the silkscreen will be visible when in the case
2019-01-01T21:19:37 < Steffanx> awh
2019-01-01T21:20:13 < bitmask> I like the back one better because it doesn't look like S's
2019-01-01T21:20:48 < bitmask> so I'll switch to it, but also it won't be on the screen when I add more heaters, its just a placeholder for disabled zones

2019-01-01T22:12:20 < emeb> given that the calibration constants stored in system ROM are based on deg C and Volts it's easiest just to use those anyway.
2019-01-01T22:21:05 < PaulFertser> emeb: the question is whether the actual Vcc needs to be measured and compensated for when using the internal temperature sensor of stm32 or not.
2019-01-01T22:28:26 < emeb> PaulFertser: I do that - it seems to help the accuracy a lot.
2019-01-01T22:28:52 < PaulFertser> emeb: that matches my experience. specing ^^

2019-01-01T22:50:06 < emeb> here's a HAL version for L432 -> https://www.dropbox.com/s/fxjjocksqrcdtls/l432_adc.c?dl=0
2019-01-01T22:51:15 < emeb> a bit more complicated because it uses power control and floats
2019-01-01T22:51:20 < bitmask> can you use the steinhart equation with the internal sensor? then actual voltage doesnt matter, just use the adc value
2019-01-01T22:52:08 < emeb> doubt it.
2019-01-01T22:52:25 < emeb> two reasons - the thermal sensor is a semiconductor junction, not an RTC
2019-01-01T22:52:59 < emeb> and the ADC reference ladder is driven by VDDA, so you can't avoid a VDD dependence.

2019-01-01T23:12:28 < aandrew> what the FUCK is the compiler emitting LDRB for
2019-01-01T23:12:44 < zyp> what's the type?
2019-01-01T23:13:07 < aandrew> twi_control_block_t *p_cb;
2019-01-01T23:13:10 < zyp> to me that looks like a struct with a uint8_t or something at offset 4
2019-01-01T23:13:13 < aandrew> yeah
2019-01-01T23:13:15 < aandrew> but look at this
2019-01-01T23:13:18 < aandrew> twi_control_block_t *p_cb;
2019-01-01T23:13:26 < zyp> yeah?
2019-01-01T23:13:29 < aandrew> p_cb = &m_cb[p_instance->drv_inst_idx];
2019-01-01T23:13:40 < aandrew> that line is emitting a single LDRB instruction
2019-01-01T23:13:44 < aandrew> that's not right
2019-01-01T23:13:44 < aandrew> at all
2019-01-01T23:13:51 < aandrew> p_cb is a fucking 32-bit address
2019-01-01T23:14:20 < zyp> are you getting hung up on source lines not matching assembly lines exactly in optimized code?
2019-01-01T23:14:55 < aandrew> it's -Og -g
2019-01-01T23:14:58 < aandrew> so it should line up
2019-01-01T23:15:12 < zyp> you're probably looking at the instruction doing p_instance->drv_inst_idx
2019-01-01T23:15:13 < aandrew> but yeah, let me do -O0 -g

2019-01-01T23:15:43 < zyp> oh, wait
2019-01-01T23:15:46 < zyp> of course
2019-01-01T23:16:21 < zyp> you're making a pointer, compiler doesn't bother actually calculation the pointer, just the offset
2019-01-01T23:16:38 < zyp> that's why you only get the p_instance->drv_inst_idx part
2019-01-01T23:17:00 < aandrew> with O0 it works
2019-01-01T23:17:04 < zyp> then you'll probably get something like [Rx, R4 SHL 2] wherever it's used
2019-01-01T23:17:12 < aandrew> no
2019-01-01T23:17:18 < zyp> then what?
2019-01-01T23:17:21 < aandrew> with Og my "address" is zero
2019-01-01T23:17:24 < aandrew> with O0 my address is correct
2019-01-01T23:17:47 < aandrew> m_cb[] is off in RAM
2019-01-01T23:17:52 < aandrew> it's a static array of a struct
2019-01-01T23:18:06 < aandrew> p_cb is calculated to point to the right element in the array
2019-01-01T23:18:09 < aandrew> but it's zero
2019-01-01T23:18:10 < aandrew> which is not right
2019-01-01T23:18:14 < aandrew> it's index zero
2019-01-01T23:18:18 < aandrew> but it's not address zero
2019-01-01T23:18:19 < zyp> can you pastebin the source?
2019-01-01T23:18:29 < aandrew> &m_cb[] should be an address
2019-01-01T23:18:30 < aandrew> yes
2019-01-01T23:18:31 < aandrew> it's not my code
2019-01-01T23:19:01 < zyp> well, from your description, it could be one of two things

2019-01-01T23:19:14 < aandrew> the comment out and ABK shit is me tryign to figure out wtf is going on
2019-01-01T23:19:23 < zyp> either it could be an actual optimizer bug
2019-01-01T23:20:00 < zyp> or it could be the code is doing something stupid and relying on undefined behavior, meaning the compiler is actually free to throw anything out and give you garbage
2019-01-01T23:20:12 < aandrew> it's like the compiler is saying "oh you want the offset into the thing, LDRB, here ya go, it's zero
2019-01-01T23:20:17 < aandrew> instead of saying the ADDRESS of element zero
2019-01-01T23:21:35 < zyp> is this atsam?
2019-01-01T23:22:31 < zyp> or I guess NRFX means nrf51/52
2019-01-01T23:22:32 < aandrew> this code is shit for sure
2019-01-01T23:22:35 < aandrew> no, it's nordic shit
2019-01-01T23:22:42 < zyp> got it
2019-01-01T23:22:48 < aandrew> they completely fucked up their SDKs when they wedged the nrf52 in
2019-01-01T23:22:54 < zyp> hehe
2019-01-01T23:22:56 < aandrew> they had nrf_drv_blahblah for everything
2019-01-01T23:23:02 < zyp> hmm, gtg, I can look more later
2019-01-01T23:23:03 < aandrew> then the new hardware in nrf52 needed some changes
2019-01-01T23:23:15 < aandrew> so they created a new api but renamed the old one nrfx
2019-01-01T23:23:24 < aandrew> but it's half calling new code and half calling old code
2019-01-01T23:23:25 < aandrew> it's a mess
2019-01-01T23:24:04 < zyp> where does m_cb come from?
2019-01-01T23:24:09 < zyp> global?
2019-01-01T23:24:32 < aandrew> yeah it's a static global in the nrfx driver
2019-01-01T23:24:43 < zyp> static?
2019-01-01T23:25:02 < aandrew> yes
2019-01-01T23:25:09 < aandrew> only that source file sees/maintains it
2019-01-01T23:25:14 < aandrew> it's all internal "method" shit
2019-01-01T23:25:24 < aandrew> I *hate* when people try to wedge C++ concepts into C code
2019-01-01T23:25:48 < zyp> static vars are fine to avoid symbol collisions
2019-01-01T23:25:51 < aandrew> anyway gonna update the compiler and see

2019-01-01T23:25:55 < aandrew> that's not old
2019-01-01T23:26:02 < aandrew> oh yes
2019-01-01T23:26:04 < aandrew> I like static vars
2019-01-01T23:26:13 < aandrew> I'm taling about m_ bullshit
2019-01-01T23:26:40 < zyp> ah, haha
2019-01-01T23:33:02 < qyx> is there any concept in prefixing methods?
2019-01-01T23:34:05 < qyx> or generally in hungarian notation
2019-01-01T23:45:28 < aandrew> fuck hungarian notation
2019-01-01T23:45:50 < aandrew> write your code clearly and you won't have to resort to psub32_lame_coder_var
2019-01-01T23:46:26 < aandrew> it's well documented that adopting hungarian notion is the reason we had the downfall of quality microsoft code
2019-01-01T23:46:49 < aandrew> nobody could write anything clearly because they were so focused on making sure all the fucking variable prefixes were correct that they forgot what they were trying to do

2019-01-02T01:00:29 < PaulFertser> Probably l152 is different
2019-01-02T01:06:57 < emeb> PaulFertser: L432 is calibrated @ 3.0V but F042 is calibrated @ 3.3V
2019-01-02T01:07:16 < emeb> I suspect that low power parts assume lower VDD for calibration.
2019-01-02T01:08:39 < qyx> in that case my current code should not work on L432 correctly
2019-01-02T01:08:51 < qyx> I'll check tomorrow

2019-01-02T03:29:41 < specing> The internal reference is supposed to be stable and Vdda-independent, correct?
2019-01-02T03:30:04 < specing> but it varies due to process variations or whatever and has to be calibrated?
2019-01-02T03:35:24 < emeb> internal reference is stable, but it's just another input to the ADC - you check it to get an idea of what VDDA is

2019-01-02T03:40:24 < englishman> some chips have an external vdda supply so you can add additional supply side filtering or decoupling. vssa might be present and separate for the same reason. some chips allow you to connect this internally as an option
2019-01-02T03:40:33 < emeb_mac> depends on which MCU & pkg - often VDDA is tied to Vref+
2019-01-02T03:41:42 < emeb_mac> but the critical thing is that Vref+ & Vref- are the top/bottom of the reference ladder in the ADC, and if those move then your readings will change even if the source is stable.
2019-01-02T03:56:45 < specing> Ok I think I know why I get strange results
2019-01-02T03:57:09 < specing> They are due to numerical errors when subtracting close numbers
2019-01-02T04:02:08 < specing> but I get 25.7'C on startup now (calculated with doubles in Octave)
2019-01-02T04:03:01 < specing> I'd say the room is at 20'C though. But I guess that is within tolerance, since ST's calibration is +- 5'C and +- 10mV Vdda

2019-01-02T04:28:11 < bitmask> I'm tired of designing around the limitations
2019-01-02T04:28:32 < Steffanx> Get a better one
2019-01-02T04:28:55 < Steffanx> Get a many-D CNC
2019-01-02T04:29:58 < Steffanx> Id be ok with https://youtu.be/AzSMliTM-eM
2019-01-02T04:46:10 < mawk> hi Steffanx 
2019-01-02T04:46:17 < mawk> you saw I got assaulted this morning
2019-01-02T04:46:20 < mawk> by some muslim
2019-01-02T04:46:31 < Steffanx> No?
2019-01-02T04:47:02 < mawk> last night I gently scared my below neighbor into making less noise with his cane
2019-01-02T04:47:16 < mawk> so this morning his son came, forced his way into my appartment, and punched me twice in the face
2019-01-02T04:47:24 < mawk> then said that he will burn everything down if I talk to the police
2019-01-02T04:47:30 < mawk> so when he left I talked to the police
2019-01-02T04:47:33 < kakimir> hmm
2019-01-02T04:47:39 < Steffanx> Whoa serious business
2019-01-02T04:47:46 < kakimir> is this uk?
2019-01-02T04:47:48 < kakimir> I assume
2019-01-02T04:47:49 < mawk> before punching me he was saying something like "don't talk to my father again, do you understand ?"
2019-01-02T04:47:59 < mawk> and I think I gave him a bit too insolent look
2019-01-02T04:48:03 < mawk> so he didn't like that and punched me
2019-01-02T04:48:27 < mawk> me kakimir ? in France
2019-01-02T04:49:11 < Steffanx> Makes me wonder how you scared the poor old man
2019-01-02T04:49:30 < mawk> I banged on his door
2019-01-02T04:49:34 < mawk> but that's all
2019-01-02T04:49:40 < kakimir> hmm
2019-01-02T04:49:44 < mawk> I didn't enter his home or anything
2019-01-02T04:50:31 < mawk> so I sued the stupid son for 4 chieves of accusation: voluntary violence, trespassing, threats to violence and threats to arson
2019-01-02T04:50:53 < mawk> but France is what it is, he will just get a slap on the fingers
2019-01-02T04:50:56 < mawk> "rappel à la loi" they call
2019-01-02T04:51:05 < mawk> a judge reads the law in front of you, asks if you understand, then you go
2019-01-02T04:52:35 < mawk> my girlfriend was very scared
2019-01-02T04:57:57 < mawk> oh and also I talked to his father again
2019-01-02T04:57:59 < mawk> he was still making noises
2019-01-02T04:58:04 < mawk> so I guess the son will show up again
2019-01-02T04:58:09 < mawk> I'll remember to not open the door that time
2019-01-02T04:58:24 < mawk> maybe I should get a fire extinguisher
2019-01-02T05:02:07 < Steffanx> And a gun
2019-01-02T05:02:42 < mawk> that's not allowed here
2019-01-02T05:02:51 < mawk> you need to be a hunter or a sports shooter
2019-01-02T05:02:55 < mawk> with a very tight license
2019-01-02T05:03:07 < mawk> but stun guns are more or less legal
2019-01-02T05:03:11 < mawk> maybe I should get one
2019-01-02T05:03:34 < mawk> here if you kill a trespasser you go to jail
2019-01-02T05:03:43 < mawk> the response needs to be proportionnate to the prejudice
2019-01-02T05:03:48 < Steffanx> Then a peephole it is
2019-01-02T05:03:57 < mawk> if the guy is stealing stuff you can't physically hurt him
2019-01-02T05:04:03 < mawk> yeah
2019-01-02T05:04:10 < mawk> but the door is almost cardboard, a few kicks and it opens I'm sure
2019-01-02T05:04:18 < mawk> let's hope he won't be angry
2019-01-02T05:05:45 < mawk> even cops are not allowed to shoot people
2019-01-02T05:05:57 < mawk> if you just draw your gun you have an immediate official investigation
2019-01-02T05:07:01 < mawk> there are rare occasions where you can shoot people when it's not a life or death situation for you
2019-01-02T05:07:26 < mawk> for instance prison guards can shoot at people trying to escape from the prison to stop them
2019-01-02T05:07:30 < mawk> after 3 oral warnings
2019-01-02T05:07:50 < mawk> even bodyguards are not allowed to carry guns
2019-01-02T05:08:00 < mawk> France hates guns
2019-01-02T05:11:34 < englishman> all the more reason to hop over to kosovo and get yourself a mitrailleuse

2019-01-02T10:04:42 < Thorn> the longer the led string (if connected in series) the higher the voltage needed to drive it, I guess this is why they don't sell led strip without resistors

2019-01-02T10:05:34 < zyp> oh, I was thinking constant current groups

2019-01-02T11:04:16 < dongs> wut
2019-01-02T11:04:32 < dongs> you just add some .c files to your shit and use
2019-01-02T11:04:40 < dongs> no idea how you do that with a makefail tho
2019-01-02T11:05:14 < Thorn> how does it allocate memory for example?
2019-01-02T11:05:34 < dongs> thats the kinda shit keil users dont care about

2019-01-02T11:06:22 < Thorn> right
2019-01-02T11:07:36 < Thorn> you just have to pay $7000, forget about the last 20 years of language improvements and learn to live with compilation times similar to those on a commodore under cp/m
2019-01-02T11:08:16 < rajkosto> Thorn, thats a feature
2019-01-02T11:08:21 < rajkosto> there are still people out there that only use msvc6.0
2019-01-02T11:09:26 < Thorn> http://arm-software.github.io/CMSIS_5/RTOS2/html/config_rtx5.html#systemConfig only describes GUI shit
2019-01-02T11:09:58 < rajkosto> (the latest keil when i used it felt like msvc6.0 to me so thats not great)
2019-01-02T11:12:55 < rajkosto> (i only did it cuz it was for a 8051 mcu that basically only could be compiled by keil and had vendor supplied .lib in keil)
2019-01-02T11:18:45 < Ecco> Hi :)
2019-01-02T11:18:55 < Ecco> Have you guys ever read about the HSI48 oscillator?
2019-01-02T11:23:19 < dongs> ecco, what about it
2019-01-02T11:23:21 < dongs> its for USB
2019-01-02T11:23:27 -!- tprrt [~tprrt@ram31-1-82-234-79-177.fbx.proxad.net] has joined ##stm32
2019-01-02T11:23:30 < dongs> and it auto-tunes by using USB timing or someshit
2019-01-02T11:23:38 < dongs> pretty sure RM covers that part
2019-01-02T11:30:37 < Ecco> Well, I'm surprised because I'm reading the AN2606 about STM32H7
2019-01-02T11:30:58 < Ecco> It says the ROMed bootloader won't do DFU without an external crystal
2019-01-02T11:31:33 < Ecco> But the refman says it has an HSI48 whose goal is to provide an USB clock that auto-corrects based on the SOF frames
2019-01-02T11:32:15 < Ecco> So I was wondering wether HSI48 could really allow for crystal-less USB, and if yes, why the ROMed bootloader didn't take advantage of this

2019-01-02T11:33:50 < zyp> I've used HSI48 in stm32l0
2019-01-02T11:34:50 < zyp> HSI48 is coupled to the CRS block (clock recovery system, or something)
2019-01-02T11:35:28 < zyp> the CRS block can be configured to look at the rate of SOF packets and use that to tune the HSI48

2019-01-02T11:46:06 < karlp> HSI48 is not the same as HSI...
2019-01-02T11:46:31 < Ecco> Yeah, apparently HSI48's sole purpose is to feed the USB controller
2019-01-02T11:46:35 < karlp> indeed.
2019-01-02T11:46:55 < karlp> hsi often works for usb for some people, but it's not specced well enough to be a reliable choice for realz
2019-01-02T11:47:08 < karlp> hsi48 is _for_ usb. it's the entire crystalless usb feature.
2019-01-02T11:47:12 < karlp> thank you patent expiry!
2019-01-02T11:47:26 < zyp> I've ran HSI48 without CRS also
2019-01-02T11:47:31 < karlp> happy new year you lot too.
2019-01-02T11:47:33 < zyp> it works until the device gets too hot
2019-01-02T11:47:41 < zyp> happy new year, karlp :)
2019-01-02T11:47:42 < karlp> zyp: well, that's just like hsi again :)
2019-01-02T11:47:46 < zyp> yeah
2019-01-02T11:48:13 < zyp> it's the CRS block that makes the HSI48 special, not the oscillator itself
2019-01-02T11:48:21 < karlp> (why do they even ofter hsi48 without crs? is it lower power than han msi+pll or hsi+pll?)
2019-01-02T11:48:36 < karlp> sure, but there'
2019-01-02T11:48:44 < karlp> s no parts with hsi48 withOUT crs.
2019-01-02T11:48:59 < zyp> I didn't say so either
2019-01-02T11:49:14 < zyp> I just hadn't written the code to turn on CRS yet
2019-01-02T11:50:44 < karlp> iirc, my board _didn't_ work until I turned crs on, but hey, that's the joy of out of spec right...
2019-01-02T11:55:17 < zyp> karlp, mine apparently worked for some hours, according to the guy using it
2019-01-02T11:59:07 < kakimir> HELLO WORK
2019-01-02T12:03:14 < rajkosto> so what happens if usb isnt connected
2019-01-02T12:06:34 < karlp> Cracki: bear in mind that's a reset if it started in bootloader mode, but received no commands on any of the other supported interfaces,
2019-01-02T12:06:40 < karlp> reboot seems like a pretty sane response there.

2019-01-02T16:33:32 < Steffanx> i cannot help you used that word.
2019-01-02T16:34:21 < Haohmaru> you assumed i intended a meaning to "speshul" which matches whatever you read on some dictionary?

2019-01-02T18:16:03 < karlp> is this h7 or somethign?
2019-01-02T18:16:09 < karlp> have you set it to output?
2019-01-02T18:20:37 < karlp> have you lookeda t RCC_C1_AHB4ENR as well?
2019-01-02T18:20:55 < karlp> os is that just the same thinga t a different address?
2019-01-02T18:23:54 < Ecco> oh, ok, eventually figured it out… lamest bug ever
2019-01-02T18:24:07 < Ecco> I was editing the wrong file, so that didn't update the GPIO MODER address :-/
2019-01-02T18:24:12 < Ecco> Anywayyyy… :-)
2019-01-02T18:24:24 < Ecco> What's RCC_C1 by the way?
2019-01-02T18:24:39 < Ecco> Next question: is there anything to do to enable the L1 cache?
2019-01-02T18:25:14 < Ecco> I eventually got my blinky runnning but it's super slow

2019-01-02T18:25:42 < Ecco> (supposedly I clocked the H7 at 400 MHz, and it's blinking 2x slower than a 100MHz F4)
2019-01-02T18:26:03 < Ecco> I left the default WS on the Flash though (7 IIRC), thinking the cache would take care of this
2019-01-02T18:26:14 < Ecco> so if the cache isn't enabled by default, that could explain it
2019-01-02T18:26:14 < karlp> well, is it _actually_ running at 400Mhz?

2019-01-02T18:27:41 < Ecco> karlp: I have no idea :-D
2019-01-02T18:27:57 < Ecco> It might indeed be running at the default 64 MHz
2019-01-02T18:28:03 < Ecco> which would explain things too :)
2019-01-02T18:28:26 < Ecco> I did the whole "configure HSE, configure PLL, switch core to PLL output"
2019-01-02T18:28:39 < Ecco> but I totally may have missed a step :)
2019-01-02T18:29:01 < Thorn> karlp: thanks, looks easier to set up than freertos
2019-01-02T18:30:09 < karlp> nah, freertos is easier IMO. (same project, different directory)
2019-01-02T18:30:10 < Thorn> Ecco: if you generate a project for your mcu using cube it will include all required initialization steps
2019-01-02T18:30:26 < karlp> freertos just has more options for apis and features to use, because it grew them all over time
2019-01-02T18:30:45 < karlp> freertos is also AllInMixecd XVhungaruain asdf SOURP shit too of course, which sucks
2019-01-02T18:31:04 < Ecco> Also, other question: it looks like the H7 doesn't have a ART (flash prefetcher)
2019-01-02T18:31:13 < karlp> (if you're using cmsis, youc an skip some of the glue for locm3 in that repo too though)
2019-01-02T18:31:17 < Ecco> I assume that's because that's superseeded by the L1 cache. Is that correct?
2019-01-02T18:31:18 < Thorn> but there's another interesting question: RTX is part of cmsis 5 while cube ships with cmsis 4
2019-01-02T18:31:57 < Thorn> I hope st-specific code will work with cmsis 5
2019-01-02T18:32:24 < Thorn> (startup code and some LL is all I need)

2019-01-02T22:11:25 < kakimir> place it in shelf "just in case"

2019-01-02T22:11:42 < Steffanx> lolno.
2019-01-02T22:11:57 < kakimir> because it's most likelly what will happen

2019-01-02T22:53:28 < Steffanx> Yay, always nice. Now i got two powerstep01 (stepper drivers) that are shorted and i have no clue why. PSU was current limited + protection, same with the powerstep01.
2019-01-02T22:53:36 < Steffanx> But apparently im not the only one with that issue.
2019-01-02T22:54:33 < Steffanx> The documentation of that chip is fucking awful. Im disappointed by ST.
2019-01-02T22:55:35 < Steffanx> Errors, lots of "TBD" and illogical order of register-bit description.
2019-01-02T22:56:20 < bitmask> nice, buttons work as expected, there is barely any axis movement but thats ok
2019-01-02T22:56:35 < englishman> what the shit is a protected tweet
2019-01-02T22:56:45 < englishman> social media makes zero sense
2019-01-02T22:57:00 < Steffanx> it seems the person made its account private englishman
2019-01-02T22:57:37 < Steffanx> it was there when Thorn  posted it, now the account is made private. I guess someone couldnt handle the load of shit she received.
2019-01-02T22:57:40 < englishman> sign up to a vanity blog site just to blog to yourself?
2019-01-02T22:57:49 < englishman> isn't that like single player counterstrike
2019-01-02T22:58:17 < Steffanx> Nah more like a rage quit. but not really quiting
2019-01-02T22:58:34 < jadew> what did the tweet say?
2019-01-02T22:58:42 < Steffanx> You have to be one of the 14k followers
2019-01-02T22:58:59 < Steffanx> it linked to https://www.newsweek.com/nasa-named-its-next-new-horizons-target-ultima-thule-mythical-land-nazi-844318
2019-01-02T22:59:02 < jadew> I don't have a twitter account

2019-01-02T23:05:51 < jadew> I need a small CNC that can do aluminium easily
2019-01-02T23:06:10 < jadew> if it could do steel, that would be better
2019-01-02T23:07:04 < jadew> budget: ~$600

2019-01-03T01:00:16 < catphish> in the uk it's illegal to distribute *anything* that might be useful to a terrorist

2019-01-03T02:31:30 < catphish> on 2019-03-29 we leave the EU automatically, if nothing is agreed by then it's over
2019-01-03T02:31:48 < tjq> ah

2019-01-03T03:11:15 < aandrew> anyone have a good USB descriptor debugger/linter?
2019-01-03T03:11:25 < aandrew> I'm sure my USB issue is due to some fucking mistake in the descriptors
2019-01-03T03:11:33 < aandrew> works perfectly fine on osx/linux, windows hates it
2019-01-03T03:14:09 < fenugrec> aandrew, USBIF had a USBHID tool years ago but it kindof sucked and was HID only
2019-01-03T03:14:43 < fenugrec> wireshark might do some generic descr parsing, I forget
2019-01-03T03:14:46 < aandrew> yeah I remember something like that

2019-01-03T03:16:20 < catphish> i think my usb issue is likely that my hub won't recognise devices untul there's actually some data passing through
2019-01-03T03:16:25 < aandrew> I remember a microsoft one that was part of some dev kit that was really nice
2019-01-03T03:16:35 < aandrew> it'd tell you that descriptor was goofy and HOW it was goofy

2019-01-03T13:11:37 < Haohmaru> maybe if they are <insert_fancy_brand_here> and uber eggspensive
2019-01-03T13:13:34 < rajkosto> nope, i did it even in the DDR2 days with the cheapest Transcend 800MHz modules
2019-01-03T13:13:45 < rajkosto> they die, go to the store, get a replacement module on the spot
2019-01-03T13:13:54 < rajkosto> they take the old one, doesnt even have to test it
2019-01-03T13:16:42 < Haohmaru> this is ddr2, no brand

2019-01-03T13:17:10 < rajkosto> would have to go to manufacturer and back

2019-01-03T13:43:19 < karlp> but that's just being obstinate really :)
2019-01-03T13:43:27 < karlp> I wouldn't want a desktop user system with only 2gig 
2019-01-03T13:43:37 < jadew> I have a laptop with 2 Gb and it takes minutes until it even boots up
2019-01-03T13:44:06 < Haohmaru> boots up - what?
2019-01-03T13:44:11 < jadew> windows 10 :P
2019-01-03T13:44:14 < Haohmaru> crapdows
2019-01-03T13:44:23 < jadew> bestos
2019-01-03T13:44:26 < Haohmaru> pls
2019-01-03T13:44:33 < rajkosto> use windows before 10 if you have less ram
2019-01-03T13:44:43 < Haohmaru> of course
2019-01-03T13:44:51 < Haohmaru> but debian ftw
2019-01-03T13:44:56 < jadew> I'll just get more RAM at some point...
2019-01-03T13:45:05 < rajkosto> they added gpu pages to the commit size/virtual paged memory in win10
2019-01-03T13:45:22 < jadew> debian is probably still on FF 1.1
2019-01-03T13:45:25 < rajkosto> this makes the required total memory size (physical + pagefile) requirement baloon up in some uses case
2019-01-03T13:45:41 < rajkosto> even win8.1 way better in that case
2019-01-03T13:47:18 < Haohmaru> i'm uber disgusted by crapdows10, even from the very GWX.EXE up to the installer
2019-01-03T13:47:32 < rajkosto> yeah luckily GWX.exe is just a memory now
2019-01-03T13:47:39 < rajkosto> so the UX on non-win10 just got even better
2019-01-03T13:47:48 < Haohmaru> and i've been reading more bad things about it
2019-01-03T13:47:49 < rajkosto> no nags or unexpected upgrades
2019-01-03T13:48:21 < rajkosto> (the way they try to one-up GWX is to have fake non-support based on CPUID, not letting windows update work on any kaby lake or ryzen+ cpu)
2019-01-03T13:48:42 < rajkosto> (even though CPUID changes nothing w.r.t. hardware support, its more the motherboard chipset that matters, even though there's drivers for all of them anyway)
2019-01-03T13:49:07 < jadew> I find windows 10 to be the best windows yet
2019-01-03T13:49:26 < jadew> boots up very fast, it's very responsive
2019-01-03T13:49:27 < rajkosto> i really see no benefit to it
2019-01-03T13:49:32 < Haohmaru> jadew pls, wash your mouth after saying such a thang
2019-01-03T13:49:33 < Haohmaru> ;P~
2019-01-03T13:49:36 < rajkosto> win8.1 has all the newer explorer/shell features without any of the bullshit
2019-01-03T13:49:46 < jadew> I skipped win 8.1
2019-01-03T13:49:50 < rajkosto> (and the DWM/driver improvements)
2019-01-03T13:49:54 < Haohmaru> win98SE woz teh best
2019-01-03T13:49:57 < jadew> went from w7 straight to 10
2019-01-03T13:50:29 < rajkosto> w7 is a little bit glitchy when used with XHCI-only motherboards and has some vsync issues because of the older WDDM 
2019-01-03T13:50:41 < rajkosto> win8/8.1 fixes all that though
2019-01-03T13:50:52 < rajkosto> literally no reason to use win10

2019-01-03T13:51:33 < rajkosto> especially not the "consumer" versions which perform pretty-much-mandatory OS reinstall every 6 months
2019-01-03T13:52:22 < rajkosto> wrecks a bunch of stuff every time, as well as requiring 30GB on your OS drive, and fragmenting it to hell
2019-01-03T13:54:35 < Haohmaru> i got 8GB ram at home on the debian
2019-01-03T13:54:51 < Haohmaru> firefox still easily sh*ts teh pants tho
2019-01-03T13:55:03 < rajkosto> run 32-bit firefox pre quantum
2019-01-03T13:55:05 < rajkosto> cant leak more than 3GB then
2019-01-03T13:55:32 < rajkosto> i still use 52 ESR because thats the last one that supports proper extensions with XUL and everything
2019-01-03T13:55:36 < Haohmaru> more like.. i avoid from the dumb websites that cause it to sh*t the pants
2019-01-03T13:55:38 < karlp> jadew: so 2 minutes is "boots up very fast" ? :)
2019-01-03T13:55:38 < rajkosto> instead of just being a chromium ripoff
2019-01-03T13:55:40 < Haohmaru> f*ck em!
2019-01-03T13:56:12 < rajkosto> ive ran all 3 OS on the same hardware recently with the same crap installed
2019-01-03T13:56:20 < rajkosto> they all get to a usable desktop in about the same amt of time.
2019-01-03T13:56:28 < rajkosto> win10 fares WAY WORSE on a hdd though, not a ssd
2019-01-03T13:56:47 < jadew> karlp, on a decent PC it boots up in seconds
2019-01-03T13:56:59 < rajkosto> win8.1 boots up in about the same time
2019-01-03T13:57:08 < Haohmaru> i don't care about boot time, since i keep teh sh*t running
2019-01-03T13:57:23 < rajkosto> win7 is a little slower to "boot" but you get to a usable desktop in about the same time (it doesnt delay startup items as much as 8/10 are)
2019-01-03T13:57:31 < Haohmaru> but my sh*t boots faster than a dumb kubuntu
2019-01-03T13:57:33 < rajkosto> w7 forever
2019-01-03T13:57:41 < rajkosto> unless you have hardware issues with it
2019-01-03T13:58:03 < rajkosto> making a slipstreamed w7 iso (which is really easy now with ntLite and its automatic update downlaoder/integrator feature) is the best OS you can install
2019-01-03T13:58:14 < jadew> when it comes to software, I've decided to always stay on the latest version as a general rule
2019-01-03T13:58:21 < rajkosto> slipstreamed updates == no waiting to get it current, or wasting disk space on uninstallable updates
2019-01-03T13:58:37 < jadew> even if the older version seems better now, in time it will start causing problems, because it doesn't get as much attention anymore
2019-01-03T13:58:53 < rajkosto> fully updated win8.1 slipstreamed with ntlite is the 2nd choice
2019-01-03T13:58:59 < rajkosto> because you need Start8 on it to make the start menu not suck.
2019-01-03T13:59:06 < rajkosto> but you need that on win10 as well, if you care about good search results in it
2019-01-03T13:59:17 < rajkosto> instead of getting random garbage/full word search only that doesnt prefer lnks/exes to documents
2019-01-03T13:59:34 < jadew> what's strat8?
2019-01-03T13:59:45 < jadew> a search provider for the start menu?
2019-01-03T13:59:51 < rajkosto> best start menu replacement for win8/10
2019-01-03T13:59:54 < Steffanx> Only good menu was xp menu
2019-01-03T13:59:56 < rajkosto> start10 exists for win10
2019-01-03T14:00:02 < Steffanx> Start10 is awful as well
2019-01-03T14:00:18 < rajkosto> there's also things like Classic Shell and StartIsBack but NONE of those have the PROPER search that gets close to win7 search
2019-01-03T14:00:23 < rajkosto> so i only use Start8/Start10
2019-01-03T14:00:23 < jadew> 10" display lol
2019-01-03T14:02:07 < Haohmaru> sleepy mau5
2019-01-03T14:02:43 < rajkosto> Cracki, isnt that a battery saving measure 
2019-01-03T14:03:04 < Haohmaru> battery saving would be to use a wired mouse
2019-01-03T14:03:06 < Haohmaru> ;P~
2019-01-03T14:03:18 < rajkosto> sometimes not an option, like if your desk is full of garbage that would impede the cord
2019-01-03T14:04:21 < rajkosto> yes it takes a large threshold before it wakes up
2019-01-03T14:04:24 < rajkosto> to save battery
2019-01-03T14:04:37 < rajkosto> because its a race to get the cheapest mouse with the longest battery life, unless its a gaymer mouse
2019-01-03T14:05:00 < rajkosto> ive been using a g700 for like 10 years now so
2019-01-03T14:05:14 < rajkosto> why its a fantastic gaymer wireless mouse
2019-01-03T14:05:25 < rajkosto> nowadays they'd just fill it with rgb
2019-01-03T14:05:25 < Haohmaru> wireless x_x
2019-01-03T14:05:31 < rajkosto> yes, a requirement for me
2019-01-03T14:05:43  * Haohmaru can't stand acceleration
2019-01-03T14:05:47 < rajkosto> acceleration is off
2019-01-03T14:05:51 < rajkosto> thats actually one thing that win10 improved
2019-01-03T14:05:56 < rajkosto> mouse acceleration being on is more natural.
2019-01-03T14:06:12 < rajkosto> didnt feel the need to turn it off in win10
2019-01-03T14:06:23 < rajkosto> and actually let me be precise and cover large distances at the same time
2019-01-03T14:06:23 < jadew> I have a cheap wireless mouse that works great
2019-01-03T14:06:31 < rajkosto> but on win7 it had to be off
2019-01-03T14:06:45 < jadew> I had to replace the buttons several times, but it has good battery life and works like you'd expect it to work
2019-01-03T14:06:55 < Haohmaru> i use whatever 3button mouse with 800dpi sensor
2019-01-03T14:06:59 < rajkosto> yes i resoldered the switches on this g700, they obviously dont last 10 years
2019-01-03T14:07:16 < Haohmaru> i usually have to put heavy junk in it
2019-01-03T14:07:31 < rajkosto> i use 1200dpi on the desktop usually
2019-01-03T14:07:35 < rajkosto> sometimes 800, sometimes 1600
2019-01-03T14:07:38 < rajkosto> thats the 3 settings in my desktop profile
2019-01-03T14:07:39 < Haohmaru> otherwise teh cable pulls it away and i get angry
2019-01-03T14:08:24 < rajkosto> one thing i cant fix on this g700 is that lcicking the wheel sticks it down for a while
2019-01-03T14:08:25 < rajkosto> cant unclick it
2019-01-03T14:08:30 < rajkosto> so i just rebound MMB to one of the side buttons
2019-01-03T14:08:48 < rajkosto> the switch for that is a very delicate kapton tape'd non-resolderable switch

2019-01-03T16:24:57 < PaulFertser> It's unclear how exactly Trevis fixed the discovered flaw.
2019-01-03T16:25:39 < PaulFertser> Probably by minimising the window the seed is in RAM but should still be there, and the moment can be pinpointed with precise FPGA timing then.
2019-01-03T16:32:03 < englishman> Trevis is a trezor guy or a guy from the talk?

2019-01-03T16:54:42 < jadew> I have a problem
2019-01-03T16:55:11 < jadew> I have a single board device, that has SMA connectors on both the front and back panels
2019-01-03T16:56:00 < jadew> how do I make it so when I tighten the SMA connectors from the outside, I don't put pressure on the board?
2019-01-03T16:57:03 < jpa-> maybe the solution is more SMAs?
2019-01-03T16:57:03 < jadew> been at this for a full day already, trying to take into account all tollerances, but it adds up to too much variance
2019-01-03T16:57:21 < Steffanx> wake up kakimir
2019-01-03T16:57:52 < jadew> what's worse, is that different SMA connectors, have different distances to the spot where they meet with the panel
2019-01-03T16:58:31 < jadew> so I have to commit to either commit to a single one, or find a magic solution to make up to 1mm (or even a bit more) not matter
2019-01-03T17:04:45 < englishman> rigidflex
2019-01-03T17:06:21 < jadew> considered that, but it would require more space and it would add maybe $10 to the BOM
2019-01-03T17:06:41 < jadew> (if not more)
2019-01-03T17:08:29 < jadew> in big test equipment, normally the PCB is screwed to a chasis and the connectors on one side can just hang
2019-01-03T17:11:45 < jadew> haha
2019-01-03T17:13:15 < jadew> yeah
2019-01-03T17:14:09 < Ecco> I'm having the weirdest bug

2019-01-03T17:14:39 < Ecco> but won't "reset halt"
2019-01-03T17:14:45 < Ecco> I can "reset" *then* "halt"
2019-01-03T17:14:55 < Ecco> but "reset halt" doesn't work
2019-01-03T17:15:12 < Ecco> also, code execution doesn't start in Flash
2019-01-03T17:15:59 < dongs> where does it start
2019-01-03T17:16:44 < Ecco> somewhere in ICTM
2019-01-03T17:17:06 < Ecco> wait
2019-01-03T17:17:10 < Ecco> I just powered it off and back on
2019-01-03T17:17:15 < Ecco> and now it started from Flash
2019-01-03T17:17:16 < Ecco> super weird
2019-01-03T17:19:09 < Steffanx> Did you screw something up with the boot pin(s) ?
2019-01-03T17:19:41 < Ecco> well, I might
2019-01-03T17:19:57 < Ecco> but in this case I should start either in flash or in the system bootloader, right?
2019-01-03T17:20:03 < Ecco> not at some random address
2019-01-03T17:32:33 < jadew> Cracki, didn't consider making the board flexible, but that wouldn't work for this thing anyway

2019-01-03T18:33:46 < dongs> no, because he still has no fucking clue
2019-01-03T18:33:58 < dongs> i am not really sure how hes wsorking for IBM *and* the new place.
2019-01-03T18:34:05 < dongs> his dicked in shows both as current employers
2019-01-03T18:34:11 < dongs> im guessing its probly neither
2019-01-03T18:34:14 < dongs> or he got sacked from IBM 
2019-01-03T18:34:21 < dongs> after his failure talk at blackhat

2019-01-03T18:56:43 < aandrew> looks like 0x40 is the minimum rx fifo size for windows
2019-01-03T19:05:46 < dongs> is this usb shit
2019-01-03T19:05:59 < dongs> 64 is the control pipe length or wahtever

2019-01-03T19:09:16 < aandrew> yes, all usb is shit 100% agreed
2019-01-03T19:09:27 < aandrew> I have a perfectly nice ethernet interface here but the client wants USB so w/e
2019-01-03T19:09:29 < aandrew> I get paid
2019-01-03T19:10:48 < dongs> solution:
2019-01-03T19:10:53 < dongs> bring up USB RNDIS interface
2019-01-03T19:11:01 < emeb> repeat the happy mantra: "I'm getting paid for this"
2019-01-03T19:11:06 < dongs> then you have 2 ethernets
2019-01-03T19:11:12  * emeb is not getting paid lately
2019-01-03T19:11:21 < dongs> is that why youre opensoresing your work
2019-01-03T19:11:54 < emeb> dongs: kinda/sorta - that was a personal project that no one cared about. might as well put it up on github
2019-01-03T19:12:33 < emeb> the only thing that happened was that customers of my clients started asking if that was a new product that the clients were coming out with.
2019-01-03T19:12:58 < dongs> heh
2019-01-03T19:14:22 < emeb> client of course remained unimpressed because it doesn't fit into his worldview

2019-01-03T19:17:16 < emeb> weltanschauung?
2019-01-03T19:17:53 < jpa-> my experiences with usb rndis: surprisingly nice to expose a HTTP API, also SOF-clock syncing works well; but not so nice is that the throughput is not as reliable as plain USB bulk endpoints, it tends to have random ~50ms pauses sometimes
2019-01-03T19:19:17 < aandrew> I've not done rndis before
2019-01-03T19:19:28 < aandrew> trying to figure out why usbview hates my descriptor
2019-01-03T19:26:10 < aandrew> in the USB init struct there is a dev_endpoints
2019-01-03T19:26:28 < aandrew> if my only interface is a bulk endpoint (in/out) is that value 2 or 3? 
2019-01-03T19:29:04 < aandrew> i.e. is EP0 considered part of that dev_endpoint count
2019-01-03T19:32:51 < aandrew> CDC seems to use a value of '4' for dev_endpoints which would not include EP0 in that case (you have data in/out and control in/out)
2019-01-03T19:33:25 < karlp> oh aandrew: https://github.com/libopencm3/libopencm3/issues/968 is the same thing you were seeing maybe.  windows doing weird things with ep0 sizes in teh name of compatibility (with broken devices, not the usb spec)
2019-01-03T19:35:13 < aandrew> wow that is exactly what I'm seeing
2019-01-03T19:37:00 < karlp> easy solyution, don't use 16bytes for ep0, 
2019-01-03T19:37:16 < karlp> everything works just fine with 32/64
2019-01-03T19:37:32 < aandrew> yeah I changed to 64 and left it
2019-01-03T19:37:43 < karlp> and there's no real need to ever use 16 anyway, unless you're trying to do this on 8bit shitvr stuff
2019-01-03T19:37:47 < aandrew> thanks for the confirmation though
2019-01-03T19:37:48 < aandrew> right
2019-01-03T19:37:55 < aandrew> I was trying to optimize the fifos
2019-01-03T19:38:08 < karlp> yeah, you can "get some more packet ram" but.... not really.
2019-01-03T19:38:20 < aandrew> since this application has almost no downstream (to device) traffic and a lot of upstream (to host) traffic, I was settin the rxfifo low
2019-01-03T19:38:23 < karlp> it's just a few extra bytes, that won't make up an entire extra packet for the other eps anyway
2019-01-03T19:38:27 < aandrew> for sure
2019-01-03T19:38:33 < aandrew> early optimization strikes again

2019-01-04T00:43:30 < upgrdman> ds2, no idea
2019-01-04T00:43:42 < ds2> too many odd user-agents seems to be coming from EC2 addresses
2019-01-04T00:43:43 < upgrdman> but running a proxy or vpn in the cloud is not exactly rare
2019-01-04T00:44:35 < ds2> yes but EC2 is expensive for just that
2019-01-04T00:45:48 < zyp> yeah, EC2 pricing doesn't seem very suitable
2019-01-04T00:45:58 < jadew> people are running the same exploitable software on VMs too
2019-01-04T00:46:28 < jadew> the fact that you're seing more traffic from that kind of addresses, could just mean that more people are using crappy hosting these days

2019-01-04T00:53:30 < catphish> yes, pcb printed
2019-01-04T00:54:09 < ds2> how did you tune them?
2019-01-04T00:54:50 < catphish> mine looks like https://i.imgur.com/OqNwJJe.png
2019-01-04T00:55:25 < catphish> i used an ST tool to calculate everything, the i tuned it by trial and error, calculations were a fair way off (like 50%)
2019-01-04T00:55:59 < kakimir> catphish: I have not followed innovation for a while
2019-01-04T00:56:07 < ds2> so no special tools like spec an's, etc?
2019-01-04T00:56:10 < kakimir> how are your projects?
2019-01-04T00:56:25 < catphish> ds2: i think zyp has a network analyzer
2019-01-04T00:57:11 < ds2> zyp: did you use a network analyzer to tune the NFC antenna?
2019-01-04T00:57:17 < catphish> kakimir: well, my board seems to work well, but i got distracted haven't finished the software, or case design, or commissioned a batch of prototypes
2019-01-04T00:57:42 < zyp> ds2, yes, I bought a minivna tiny just for it
2019-01-04T00:57:45 < catphish> assembled: https://i.imgur.com/o4ZSdrO.jpg
2019-01-04T00:58:31 < zyp> I didn't bother calculating too much, I just drew a spiral in the area I had convenient and tuned it until it resonated properly
2019-01-04T00:58:44 < ds2> zyp: nice... how did you use it? I see a few methods out there - a sense coil (a la the old dip meter) and some direct connection methods
2019-01-04T00:59:37 < zyp> https://bin.jvnv.net/file/m0yyr.JPG <- for tuning, I just stacked caps until the vna showed it hitting the right frew

2019-01-04T01:00:10 < zyp> https://bin.jvnv.net/file/uNgNm.JPG <- I cut the traces to the chip and soldered to the inductors
2019-01-04T01:00:34 < ds2> but how did you attach the VNA
2019-01-04T01:00:35 < zyp> disregard the missing part, that one was harvested after tuning :p

2019-01-04T01:01:03 < zyp> that's a coax, running to the VNA
2019-01-04T01:01:30 < ds2> ah I see it now
2019-01-04T01:01:43 < catphish> as zyp said, dont worry about the calculations, just make a spiral in whatever space you can spare
2019-01-04T01:01:46 < ds2> but doesn't the 50ohm input to the VNA load down the antenna?
2019-01-04T01:02:32 < zyp> you tune the antenna until it hits the same 50 ohms :)
2019-01-04T01:03:05 < catphish> it's also worth noting that it will work *way* out of tune
2019-01-04T01:03:07 < ds2> this is where I don't understand - how can a resonant tank be at 50ohm? isn't that too low of a Q?
2019-01-04T01:03:31 < catphish> mine worked fine with no tuning at all, it wasn't until i needed super low power that i had to tune it carefully
2019-01-04T01:03:33 < zyp> idk, I'm not a pro on that math
2019-01-04T01:03:37 < ds2> really? I just need to be in the ball park? (unlike far field/2.4G type antenna)
2019-01-04T01:03:57 < zyp> but I figure that's the point of the matching network
2019-01-04T01:04:30 < catphish> zyp: i wonder if yours is perfectly tuned as you think, or working regardless, because i was astonished how well mine worked (excluding card detection) before i tuned it
2019-01-04T01:04:37 < ds2> okay, think I'll try a direct connection... a dip meter type interface SEEMS the most intuitive
2019-01-04T01:04:45 < zyp> catphish, probably working regardless
2019-01-04T01:04:56 < zyp> I'm not claiming it's perfectly tuned
2019-01-04T01:05:09 < catphish> i didn't realise i'd fucked it up until i tried to use card detection, which relies on the resonance
2019-01-04T01:05:21 < zyp> I still haven't tried that
2019-01-04T01:05:37 < zyp> have you tested range?
2019-01-04T01:05:45 < zyp> mine reads card fine through 20mm solid wood
2019-01-04T01:05:49 < zyp> or more
2019-01-04T01:05:56 < catphish> without tuning, it still coupled to the card ok, just can't self resonate
2019-01-04T01:06:05 < ds2> I'd be happy if worked 0.500 away
2019-01-04T01:06:15 < catphish> 0.5 what?
2019-01-04T01:06:15 < ds2> even 0.250 would be good :D
2019-01-04T01:06:20 < ds2> 0.500in
2019-01-04T01:06:33 < catphish> that should be quite achieveable
2019-01-04T01:06:45 < ds2> <super>*</super>All dimensions are in inches unless otherwise specified :D
2019-01-04T01:06:47 < zyp> should be no problem at all

2019-01-04T01:07:25 < catphish> also for the love of god learn metric
2019-01-04T01:07:36 < zyp> ds2, haha
2019-01-04T01:07:39 < catphish> don't bother
2019-01-04T01:07:42 < catphish> use PCB
2019-01-04T01:07:44 < BrainDamage> ds2: you're using the wrong definition of Q, the valid one for RF is energy_dissipated/cycle_energy characteristic impedance is NOT dissipation
2019-01-04T01:07:46 < zyp> agreed
2019-01-04T01:08:01 < zyp> the antenna shape doesn't really matter much, since you can just adjust the caps to match
2019-01-04T01:08:16 < catphish> just make a PCB, make the antenna 3-4 turns of 20-40mm, it'll be fine
2019-01-04T01:08:34 < catphish> regardless of the anntenna, you can tune it later
2019-01-04T01:08:45 < catphish> just be sure to make space for several caps in parallel
2019-01-04T01:09:36 < ds2> BrainDamage: Do you mind explaining? characteristic impedence can be modeled as a R (i.e the terminator)... so how is that different if I am slapping 50ohm across the tank?
2019-01-04T01:09:38 < catphish> zyp: card detection only woks to about 20mm air gap, but that's good enough, then once it powers up, the range is obviously much more than that

2019-01-04T01:10:14 < ds2> supposely an unshielded ferrite inductor can work too but I have had 0 luck there
2019-01-04T01:10:17 < BrainDamage> ds2: a resistor dissipates, a char impedance doesn't necessarily so
2019-01-04T01:10:55 < BrainDamage> eg a pure LC network can show you 50Ohm despite not dissipating one bit
2019-01-04T01:11:33 < ds2> hmmmm
2019-01-04T01:12:00 < BrainDamage> think also of a waveguide
2019-01-04T01:12:15 < ds2> Given what you are saying, would this be true - a pure LC network @ resonance will absorb power at the same rate that a 50ohm resistor will?
2019-01-04T01:12:15 < BrainDamage> it has 50Ohm char impedance, but the dissipation is unrelated to that
2019-01-04T01:12:46 < BrainDamage> it's not a pure LC resonance
2019-01-04T01:12:57 < BrainDamage> it's LC resonance coupled with the vacuum's
2019-01-04T01:13:21 < BrainDamage> you're not seeing the LC's resonance, but the resonance of the whole thing
2019-01-04T01:13:53 < ds2> then where is the energy going in a pure LC setup (nothing else coupling to it)?
2019-01-04T01:13:56 < BrainDamage> if it was at the LC's pure resonance, then you'd only see the R component of the LC
2019-01-04T01:14:22 < ds2> which would be 0 for ideal L and C
2019-01-04T01:14:32 < BrainDamage> yup, you get 0 dissipation in an ideal LC
2019-01-04T01:14:39 < BrainDamage> and you'd see 0 or infinite resistance
2019-01-04T01:15:29 < ds2> maybe I have a defective understanding of dissipiation

2019-01-04T01:38:19 < ds2> built up a BLE connected PM2.5/PM10 pollution sensor that sends data ultimately to a MQTT broker; a cron job reads the MQTT data and places it in a RRDtool database. that line generates a graph from that
2019-01-04T01:38:47 < karlp> how do you use a cron job to read mqtt?
2019-01-04T01:39:04 < karlp> are you relying on qos >= 1 and queueing between cron runs?

2019-01-04T02:00:07  * karlp shrugs. doesn't really matter I guess.
2019-01-04T02:00:16 < karlp> ec2 is great for tuning them on an off easily.
2019-01-04T02:00:44 < karlp> I mean, linode has hourly billing too if you like, but still, ec2/aws is great for "turn on my personal vpn provider now plz"
2019-01-04T02:01:44 < zyp> yeah
2019-01-04T02:02:32 < zyp> the way I see it, the biggest advantage of aws is super flexible scaling, everything is designed to scale up and down depending on demand
2019-01-04T02:03:01 < ds2> for practical stuff, linode is miles cheaper then EC2
2019-01-04T02:03:53 < zyp> yes
2019-01-04T02:04:17 < zyp> but also less flexible
2019-01-04T02:04:45 < ds2> yes but I rather not get nickled and dimed w/no easy to estimate cap on the expense
2019-01-04T02:05:19 < zyp> I mean, I use linode myself, but I can see the point of aws too, it just doesn't fit my use

2019-01-04T02:16:53 < zyp> the thing is that the alternative isn't nothing, the alternative is being at the old apartment which still has a 500/500 connection that's paid for until the end of the month :p
2019-01-04T02:18:26 < zyp> the way I see it, until I have internet that's actually usable for streaming video at the new house, there's not much point in moving the tv, and there's also not much point in moving the couch before I move the tv

2019-01-04T02:28:53 < BrainDamage> pull a fiber into their box
2019-01-04T02:28:57 < BrainDamage> specing: italy
2019-01-04T02:29:15 < zyp> hehe
2019-01-04T02:29:47 < specing> BrainDamage: interesting
2019-01-04T02:30:12 < BrainDamage> we suck for many things, but not cell radio
2019-01-04T02:30:28 < zyp> BrainDamage, free roaming also?
2019-01-04T02:30:55 < specing> BrainDamage: is that why you have such a huge deficit?
2019-01-04T02:30:59 < zyp> can you get me a 100G plan and just mail me the simcard? :p

2019-01-04T02:32:20 < BrainDamage> zyp: free roaming in EU, maybe norway too, I need to check if it's "enough EU"
2019-01-04T02:32:55 < specing> pretty sure its 1GB in EU or some such
2019-01-04T02:32:59 < zyp> all norwegian companies also offers free roaming in EU, since we're part of EEA
2019-01-04T02:33:05 < ds2> when did free roaming in EU come into effect?
2019-01-04T02:33:18 < zyp> summer 2017, wasn't it?
2019-01-04T02:34:07 < ds2> ah more recent then 2014... couldn't roam in FR with a UK sim at that time
2019-01-04T02:34:17 < ds2> (at least not for free)
2019-01-04T02:35:18 < zyp> I remember having to pay for data when I went to .dk in spring 2017
2019-01-04T02:35:32 < zyp> but when I went to .uk in fall 2017, I didn't
2019-01-04T02:35:35 < zyp> heh
2019-01-04T02:35:44 < zyp> wonder how that's gonna turn out after brexit
2019-01-04T02:37:11 < jadew> I don't remember, anyone here doing stock market trading or just currency?
2019-01-04T02:39:00 < BrainDamage> 60GB costs 10€, ( it's 9€ + 1€ for LTE which is free for the the first 6 months ), unused monthly traffic carries over the successive months. there's an activation cost of 60 bucks, which become 0 if you carry over the contract for at least 24 months or (or 30 months if you rent the modem), you pay it if you rescind the contract
2019-01-04T02:39:09 < BrainDamage> sec that I'm checking the roaming areas
2019-01-04T02:41:08 < BrainDamage> you're covered by full roaming, so no extra costs
2019-01-04T02:42:02 < ds2> no restrictions on duration of roaming?
2019-01-04T02:42:06 < BrainDamage> none
2019-01-04T02:42:11 < ds2> nice
2019-01-04T02:42:41 < BrainDamage> I have a friend that lives in france that uses an italian sim
2019-01-04T02:43:06 < tjq> hmm
2019-01-04T02:43:24 < tjq> sim cards ey
2019-01-04T02:44:04 < zyp> cheapest 50GB plan here seems to be €45
2019-01-04T02:44:34 < specing> sounds interesting BrainDamage, maybe I'll buy one next I visit trieste

2019-01-04T02:51:06 < specing> nice, 6 eur per month home internet seems nice
2019-01-04T02:51:11 < specing> what is the speed limit on it?
2019-01-04T02:51:42 < BrainDamage> tjq: here it merged with another company, that's why it's still alive
2019-01-04T02:54:02 < specing> BrainDamage: Here there is 200GB for 15 eur montly, prepaid
2019-01-04T02:54:11 < specing> but no good cheaper package
2019-01-04T02:54:25 < zyp> hey, that sounds nice
2019-01-04T02:54:53 < specing> bandwidth limit is 25/5, but can be raised to 50/20 for additional 2 eur
2019-01-04T02:55:07 < zyp> does that mean you can just sign up, put in €15, use 200GB, then throw it away?
2019-01-04T02:55:12 < specing> yep
2019-01-04T02:55:18 < specing> the SIM costs 2 eur in store
2019-01-04T02:55:34 < BrainDamage> specing: 100MBit down, 50Mbit up
2019-01-04T02:55:53 < specing> BrainDamage: woah!
2019-01-04T02:55:57 < zyp> specing, also with roaming?
2019-01-04T02:56:18 < specing> zyp: only a small amount is included for EU roaming, around 5 GB
2019-01-04T02:56:23 < zyp> aw
2019-01-04T02:56:29 < zyp> that's no fun
2019-01-04T02:57:10 < zyp> hmm, wonder if prepaid data plans exists here at all
2019-01-04T02:57:57 < BrainDamage> also, RE: roaming rules, until the 31st of 2018 companies were allowed to overtax foreign traffic past a certain limit
2019-01-04T02:58:10 < specing> zyp: usually if there is a tourism industry they will exist
2019-01-04T02:58:11 < BrainDamage> eg it was 4GB for tre
2019-01-04T02:58:17 < specing> zyp: but might be lame
2019-01-04T02:58:30 < zyp> specing, I'm thinking data plans, not phone+data plans
2019-01-04T02:58:35 < BrainDamage> but since this year's jan, they cannot
2019-01-04T02:58:56 < zyp> the latter exists, but those aren't any better than the phone plan I've already got

2019-01-04T11:50:53 < marble_visions> hi all, i'm trying to make sense of the stm32l011 i2c master transmit.. there's a flowchart in the refman at the end of which it says that if i2c.isr.tc = 0 i'm done, but if it 1, i need to do something and then there are ellipses (...) and i don't know what to do

2019-01-04T11:51:01 < marble_visions> page 607
2019-01-04T11:51:22 < marble_visions> does a tc = 1 mean that something's failed and i need to restart the tx procedure?
2019-01-04T11:51:42 < marble_visions> also, it is not a multimaster setup and i'm sending less than 256 bytes
2019-01-04T11:52:26 < marble_visions> from the rest of the text i make out that tc is used in transfers of more than 255 bytes
2019-01-04T11:53:14 < marble_visions> of used in software end mode as well
2019-01-04T11:53:58 < marble_visions> so if i'm using automatic stop and no dma i shouldn't be concerned with tc at all?
2019-01-04T11:55:10 < marble_visions> just wondering, i am seeing correct behavior on scl and sda
2019-01-04T11:55:18 < marble_visions> so it's not a big issue

2019-01-04T12:08:18 < marble_visions> i was thinking roughly the same, but then if tc is not 1, how do you initiate another transfer again down the line at some point in the future? shouldn't TC become 1 regardless of whether or not i want to transmit again?
2019-01-04T12:11:01 < marble_visions> Cracki: right
2019-01-04T12:11:24 < marble_visions> that makes sense, being relevant only to software stop mode

2019-01-04T13:44:53 < Haohmaru> eveis
2019-01-04T13:45:12 < jpa-> if you really have a situation where simple parity is not enough, your dual-byte scheme doesn't improve the reliability much

2019-01-04T13:47:58 < karlp> even parityis dubious when you have crc too

2019-01-04T13:51:56 < karlp> My favourite is mark and space parity
2019-01-04T13:52:05 < karlp> aka, "let's just pad the frame for fun"
2019-01-04T13:52:20 < kakimir> I don't understand
2019-01-04T13:54:18 < karlp> you commonly only hear of even or odd parity bits,
2019-01-04T13:54:28 < karlp> but lots of hardware has support for "mark" and "space" parity too
2019-01-04T13:56:32 < kakimir> should look into it
2019-01-04T13:56:47 < karlp> are you having communications errors?
2019-01-04T13:57:01 < marble_visions> kakimir: do you have the resources for a crc8/16 in software?
2019-01-04T13:57:13 < marble_visions> also, what karlp just said

2019-01-04T13:57:33 < kakimir> I have code based crc ofc
2019-01-04T13:57:34 < kakimir> but
2019-01-04T13:57:56 < kakimir> nah man
2019-01-04T13:58:04 < kakimir> I don't throw that beast in there
2019-01-04T13:58:20 < kakimir> I have better uses for flash
2019-01-04T13:58:36 < srk> run vusb on it

2019-01-04T13:59:35 < karlp> or "I don't go for haskell"
2019-01-04T13:59:43 < Steffanx> Yes arlp
2019-01-04T14:00:43 < marble_visions> kakimir: crc can be fast and lean: https://en.wikipedia.org/wiki/Cyclic_redundancy_check#Polynomial_representations_of_cyclic_redundancy_checks
2019-01-04T14:00:45 < srk> just add 1G of sram and sdcard so you can boot linux on it, then it is easy
2019-01-04T14:00:54 < kakimir> attiny has only odd and even parity for usart
2019-01-04T14:01:11 < marble_visions> i've seen chips that do "checksums" by counting all the data bytes
2019-01-04T14:04:16 < karlp> you can get into info theory and even jsut choose to do a checksum instead ofa  crc
2019-01-04T14:07:17 < kakimir> my data amounts are very small
2019-01-04T14:07:23 < kakimir> and not in hurry
2019-01-04T14:07:40 < kakimir> just few bytes at time from target to tester
2019-01-04T14:07:57 < kakimir> plannin to use 9600 or so because - no hurry
2019-01-04T14:09:52 < kakimir> just identification data first and then it's all few fault flags per test
2019-01-04T14:10:12 < kakimir> and some measured values
2019-01-04T14:10:19 < kakimir> 2byte max values
2019-01-04T14:10:45 < jpa-> i can't see why you'd need anything more than just parity there
2019-01-04T14:11:38 < kakimir> parity isn't a strong checksum
2019-01-04T14:11:53 < kakimir> it's really weak really basic
2019-01-04T14:11:58 < kakimir> I want extra level
2019-01-04T14:12:17 < kakimir> that requires complex data error to be fooled
2019-01-04T14:12:33 < kakimir> but is cheap in terms of flash size
2019-01-04T14:13:27 < kakimir> inverting is cheap
2019-01-04T14:13:36 < jpa-> yeah, feel free to pick your favourite checksum algorithm, i'm just saying that i can't see what improvement that would make - even single bit errors should be rare enough
2019-01-04T14:14:17 < kakimir> I don't recall seeing any errors latelly
2019-01-04T14:14:19 < jpa-> one point is that properly handling parity errors on PC with portable software is difficult, so it may be easier to add a custom scheme
2019-01-04T14:14:42 < kakimir> I didn't say pc
2019-01-04T14:14:53 < jpa-> i did
2019-01-04T14:15:18 < kakimir> I mean I have pulled megabytes of logs from mcu without a single error
2019-01-04T14:15:24 < kakimir> at 115200
2019-01-04T14:15:26 < kakimir> without any checks
2019-01-04T14:15:43 < Steffanx> How you know?
2019-01-04T14:15:53 < kakimir> sorry
2019-01-04T14:16:01 < kakimir> *no apparent errors
2019-01-04T14:16:20 < Steffanx> :P
2019-01-04T14:16:30 < kakimir> numerical data can have errors without noticing it
2019-01-04T14:16:41 < jpa-> the main error class that parity doesn't catch is framing errors, but a simple inversion scheme doesn't catch that very well either
2019-01-04T14:16:42 < kakimir> if only low bytes are flipped
2019-01-04T14:16:52 < jpa-> whereas just "sum of all bytes in specific field in the packet" already does

2019-01-04T14:55:55 < Ecco> I'm trying to port code that talks to an LCD using the FSMC from F4 to H7
2019-01-04T14:56:51 < Ecco> for some reason, the single address bus bit that is used doesn't toggle the same way on F4 and H7
2019-01-04T14:57:18 < dongs> .
2019-01-04T14:59:38 < Ecco> It's very weird, I can send commands to the LCD panel, but not pixel data :/
2019-01-04T15:05:40 < kakimir> what is the de facto parity for usart comms?
2019-01-04T15:05:51 < kakimir> not that it matters which one is used
2019-01-04T15:06:19 < kakimir> is it better to use multiple stop bits compared to 1?
2019-01-04T15:06:39 < specing> de facto is no parity
2019-01-04T15:07:04 < kakimir> yes
2019-01-04T15:07:10 < kakimir> but in case parity is used?
2019-01-04T15:08:50 < Thorn> kakimir: >1 stop bits is required for mechanical teletypes
2019-01-04T15:09:10 < Thorn> if you're using electronics you shouldn't need that

2019-01-04T15:37:40 < Thorn> seems like every compiler course ends up being mostly about parsing, as if it's the most important thing in the compiler. almost no time is spent on code generation and optimizations
2019-01-04T15:39:50 < zyp> well, it makes sense, parsing is the hardest part of making something basic
2019-01-04T15:40:34 < zyp> you can halfass code generation and skip optimizations and still produce working code, but your parser needs to be able to handle the full source syntax

2019-01-04T16:40:03 < karlp> yeah, fari enough, though there's still a metric fuckton that don't do parity.
2019-01-04T16:40:23 < karlp> ti also says that 19200@8e1 should be default too, not 9600@8n1 like heaps of people do

2019-01-04T20:16:25 < Ecco> I've narrowed it down though
2019-01-04T20:16:37 < Ecco> I'm using the FMC using a 16-bit bus
2019-01-04T20:17:13 < Ecco> on an STM32F4, doing a 16-bit write to the FMC yields a single write to the pins on the STM32
2019-01-04T20:17:40 < Ecco> on the H7, doing a 16-bit write to the FMC yields… 3 writes
2019-01-04T20:18:04 < Ecco> (the NWE pin is toggled 3 times, and the data pins also move several times
2019-01-04T20:18:10 < Ecco> I have *no* idea what's going on
2019-01-04T20:20:30 < Thorn> Ecco: the cache is your enemy

2019-01-04T20:38:36 < zyp> doesn't make too much sense either way
2019-01-04T20:38:40 < Ecco> but anyway, how could cache explain multiple memory transaction after the FMC?
2019-01-04T20:38:47 < Ecco> indeed :)
2019-01-04T20:39:24 < Ecco> But using a logic analyzer, I can definitely see multiple oscillations on NWE for a single write
2019-01-04T20:39:42 < Ecco> (e.g. *0x60000000 = 0x1234 yields 4 oscillations of NWE)
2019-01-04T20:39:47 < qyx> can you decode what is it trying to write?
2019-01-04T20:39:51 < zyp> are you sure it's exactly three and you're not seeing aliasing?
2019-01-04T20:40:14 < Ecco> qyx: not entirely, I only have an 8-port analyzer
2019-01-04T20:40:37 < Ecco> zyp: I don't knkow
2019-01-04T20:41:02 < Ecco> even weirder, the CSX pin is also toggled at some point during the write :-/
2019-01-04T20:41:47 < zyp> ah, but you're not looking at addrs that get written?
2019-01-04T20:42:00 < Ecco> https://i.imgur.com/AjPHHe7.png
2019-01-04T20:42:15 < Ecco> I have an LCD panel connected to the bus
2019-01-04T20:42:19 < Ecco> not an actual memory
2019-01-04T20:42:40 < Ecco> What's very weird is that the first part of the write is correct because the LCD panels reacts properly
2019-01-04T20:43:20 < Ecco> when I want to send 16 bits, apparently 64 are sent
2019-01-04T20:43:30 < zyp> sure it's not 128?
2019-01-04T20:43:49 < Ecco> not positive
2019-01-04T20:44:12 < Ecco> -> If the LCD instruction is 16-bit long, then it works, because the correct instructions is sent first, then 3 garbage instructions

2019-01-04T20:45:18 < zyp> I figure if cache is involved here, it might be flushing whole cache lines
2019-01-04T20:46:01 < zyp> if you have A0/A1 available, they would be interesting to see
2019-01-04T20:46:12 < Ecco> well I guess I could write it up
2019-01-04T20:47:51 < zyp> hmm, seems that cache lines are 256 bits, so that doesn't make all that much sense

2019-01-04T20:59:43 < emeb> jlcpcb order placed sun eve. arrived just now. 
2019-01-04T20:59:49 < englishman> wow
2019-01-04T21:00:29 < emeb> standard processing, standard shipping.
2019-01-04T21:01:14 < emeb> granted their std shipping is DHL express which cost ~$17 - roughly the same as the fab cost.
2019-01-04T21:01:27 < englishman> that's still pretty cheap
2019-01-04T21:01:51 < englishman> i couldn't ride on an A330 for $17
2019-01-04T21:01:58 < qyx> last time I DHL'd something from china, it was stuck at customs for a week
2019-01-04T21:02:03 < emeb> Yeah. 5x ea of 3 different designs.
2019-01-04T21:06:44 < englishman> i paid much more than that in china for some 140mm wide designs with enig but the silkscreen still sucks dick so it kind of wasn't worth it
2019-01-04T21:07:15 < Steffanx> Standard shipping is dhl?!
2019-01-04T21:08:46 < bitmask> they have cheaper but its only very slightly cheaper and takes twice as long
2019-01-04T21:09:17 < bitmask> for me it was 13 for 8-14 day and 16 for 2-7 day or whatever it is
2019-01-04T21:09:24 < bitmask> dhl being $16

2019-01-04T21:37:59 < Steffanx> and
2019-01-04T21:38:01 < catphish> yeah it does seem to be pretty much mostly lakes
2019-01-04T21:38:06 < qyx> did you remember some obvious change before I start digging?
2019-01-04T21:38:52 < Steffanx> and you can even take a train to St. Petersbrug if you want to catphish.

2019-01-04T21:48:01 < qyx> recently I was browsing some .fi sites selling islands
2019-01-04T21:48:19 < qyx> you can get one for ~50keur
2019-01-04T21:48:25 < Steffanx> yay.
2019-01-04T21:48:35 < qyx> even less but they are hardly usable for anything
2019-01-04T21:48:49 < Steffanx> If you like camping...
2019-01-04T21:49:11 < qyx> thts not the problem
2019-01-04T21:49:17 < qyx> either there were no tress, rocks only
2019-01-04T21:49:21 < Steffanx> ah
2019-01-04T21:49:21 < qyx> or it was too flat
2019-01-04T21:49:33 < qyx> or a similar issue
2019-01-04T21:50:13 < qyx> I would fear that a moderate storm could wash everything away
2019-01-04T21:50:21 < Thorn> do you want an island with a mountain to build your castle on top of it?
2019-01-04T21:50:42 < Steffanx> Example code as an installer (exe) WTF are you doing infineon
2019-01-04T21:51:26 < Steffanx> oh lol. And after installing you get a directory with a zip. LOL
2019-01-04T21:51:56 < qyx> Thorn: no, something like this would suffice https://ak.picdn.net/offset/photos/5a720cda17fb156e48075f0b/medium/offset_655137.jpg
2019-01-04T21:52:13 < qyx> but as I say, being slightly higher
2019-01-04T21:52:19 < Thorn> Steffanx: try opening that exe with 7zip or winzip or something, it might work
2019-01-04T21:52:52 < qyx> islands like this are too flat http://i.imgur.com/PBM2Ii3.jpg
2019-01-04T21:53:07 < Steffanx> 7z cant do it Thorn
2019-01-04T21:53:21 < Steffanx> still pretty cool actually.
2019-01-04T21:53:32 < Steffanx> but i wouldnt like getting from and to my house with a boat.
2019-01-04T21:54:09 < qyx> you can always get a heli

2019-01-04T22:09:07 < mawk> the chip has two SPI word size, the first is 8 bits, classical
2019-01-04T22:09:12 < mawk> the second is 12 bits
2019-01-04T22:09:16 < mawk> who designed that
2019-01-04T22:09:47 < qyx> did you remember words sizes in PIC?
2019-01-04T22:09:51 < qyx> *do
2019-01-04T22:10:41 < mawk> I never used PIC
2019-01-04T22:11:03 < mawk> they could've used right-aligned 16 bits and then be compatible with the rest of the world
2019-01-04T22:11:22 < mawk> maybe it's just the linux spi module that can't but the SPI peripheral on the SoC can
2019-01-04T22:12:04 < qyx> Program instructions vary in bit-count by family of PIC, and may be 12, 14, 16, or 24 bits long
2019-01-04T22:13:08 < mawk> yeah I said word size but it was just SPI word size
2019-01-04T22:13:16 < mawk> number of bits per half transfer
2019-01-04T22:13:20 < jpa-> mawk: the timing diagrams seem to show 24 bits in the transfer, even though part of it is "X"
2019-01-04T22:13:34 < jpa-> so basically just 3 bytes
2019-01-04T22:13:48 < mawk> yeah I guess I can do it like that
2019-01-04T22:13:56 < mawk> I was using two half-duplex transfers
2019-01-04T22:14:04 < mawk> good idea

2019-01-04T22:20:25 < mawk> but it's nonetheless ugly
2019-01-04T22:20:54 < jpa-> how so?
2019-01-04T22:21:06 < mawk> I'll have to send zeroes at the end of the tx buf, and put zeroes at the beggining of rx buf
2019-01-04T22:21:22 < jpa-> .. like you always do with spi?
2019-01-04T22:21:49 < mawk> I do it when I can't do it otherwisz
2019-01-04T22:22:07 < mawk> the linux spi device let's you do half-duplex transfers in turn
2019-01-04T22:22:13 < mawk> like god intended
2019-01-04T22:22:15 < jpa-> if you want to do it with half-duplex transfers, you can do a 2-byte send and 1-byte receive/send
2019-01-04T22:22:44 < jpa-> like the timing diagrams show, the X's are in the middle so that the last byte is aligned on a byte boundary
2019-01-04T22:23:08 < mawk> yeah
2019-01-04T22:23:10 < jpa-> but i'm pretty sure the half-duplex transfer just adds the zeros in the driver
2019-01-04T22:24:17 < mawk> yeah
2019-01-04T22:24:23 < mawk> I guess
2019-01-04T22:24:46 < mawk> <linux/spi/spidev.h> should say it
2019-01-04T22:25:49 < jpa-> besides, two half-duplex transfers sounds like double the syscall overhead, which can be quite significant when the transfer itself is just microseconds
2019-01-04T22:26:30 < mawk> and it does, iirc
2019-01-04T22:35:52 < catphish> buying a cheap island would be nice, i'd want to build a simple cabin on it though, so washing away is no good :(
2019-01-04T22:36:02 < catphish> jpa-: i'll look up jyväskylä :)
2019-01-04T22:37:40 < englishman> you can do what the floridians do, and just buy a mobile home. then when it gets blasted by a hurricane, just get another
2019-01-04T22:38:16 < jpa-> if it's on a lake, it's not like you get particularly huge storms in finland
2019-01-04T22:43:55 < catphish> some pleasant places around there :)

2019-01-04T23:21:26 < mawk> jpa- if it was two syscalls I'd just use a single full-duplex with padding
2019-01-04T23:21:30 < mawk> I'm aiming for the most elegant
2019-01-04T23:21:49 < mawk> it's a single syscall, you specify a list of operations to do in a single chip selection
2019-01-04T23:21:58 < mawk> each operation can be half-duplex or full-duplex, you can wait between them, etc
2019-01-04T23:22:17 < mawk> you use some ioctl with a list of struct spi_ioc_transfer
2019-01-04T23:22:35 < mawk> akin to linux syscalls taking I/O vectors as parameters
2019-01-04T23:22:39 < mawk> readv, writev
2019-01-04T23:25:52 < mawk> I went with the bare-metal kernel interface because all the RPi libs look like having stupid interfaces
2019-01-04T23:26:19 < mawk> also it's the POSIX interface that's on the system I'm eventually targeting

2019-01-05T00:47:35 < BrainDamage> but until the early 2000s, there weren't popular in car stereos
2019-01-05T00:50:34 < upgrdman> i wish my 2005 toyota stereo was less basic. it can play cd's and that's about it. no aux in, no usb, no mp3 or dvd support, no bluetooth, etc.

2019-01-05T00:52:15 < upgrdman> my first mp3 player had fm tx... Neuros something. kinda miss it, but it was big and had meh battery life.

2019-01-05T00:54:13 < Steffanx> What does it do, tjq?
2019-01-05T00:54:20 < bitmask> I added a usb port with mp3 playback, hd radio, bluetooth audio with an iSimple but that requires a satellite input

2019-01-05T00:56:02 < tjq> Before hanging himself
2019-01-05T00:56:18 < BrainDamage> transmit to an empty band and tune from the cat stereo
2019-01-05T00:56:28 < upgrdman> BrainDamage, yes. but do they sound decent? last time i tried them, they sounded like ass
2019-01-05T00:56:48 < qyx> ass-128
2019-01-05T00:56:49 < BrainDamage> when I say cheap shit, I mean cheap shit
2019-01-05T00:57:02 < upgrdman> but muh FLAC
2019-01-05T00:57:10 < upgrdman> j/k, but ya, i want decent sound.
2019-01-05T00:57:20 < BrainDamage> replace the car stereo
2019-01-05T00:57:29 < BrainDamage> there's "universal" connectors
2019-01-05T00:57:36 < BrainDamage> you can replace even OEM dashboards
2019-01-05T00:57:48 < BrainDamage> you'll just get unsightly front panels
2019-01-05T00:58:19 < Steffanx> I replaces mine. It looks pretty much like the original panel
2019-01-05T00:58:22 < upgrdman> car isn't worth much now, heh. im tempted to just buy a new car. my car works fine, but is showing it age. paint is oxidized, seat upholstry is fraying, etc.
2019-01-05T00:58:23 < Steffanx> Replaced*
2019-01-05T00:58:29 < upgrdman> not worth pouring money into it :(
2019-01-05T00:58:36 < karlp> upgrdman: yeah, audio quality on an fm tx I had was apalling
2019-01-05T00:58:36 < Steffanx> It runs android now.
2019-01-05T00:58:39 < Steffanx> Yay.
2019-01-05T00:58:55 < karlp> I loved my old headunit that plaued mp3s on cds had a whole stack of ~7-10 albums per disc, super nice.
2019-01-05T01:01:59 < tjq> Imagine a world without arduino
2019-01-05T01:02:20 < BrainDamage> it was bound to happen
2019-01-05T01:02:37 < BrainDamage> if it wasn't arduino, it would've been something else later
2019-01-05T01:02:46 < tjq> Was testing if dong was awake
2019-01-05T01:02:59 < upgrdman> basic stamp 2 was a thing
2019-01-05T01:03:00 < tjq> :D
2019-01-05T01:03:07 < upgrdman> i had one before the arduino
2019-01-05T01:03:12 < tjq> Picaxe that was filth
2019-01-05T01:03:17 < Steffanx> Hahha
2019-01-05T01:03:19 < upgrdman> sucked ass, since you had to code in basic, but ya it worked i guess
2019-01-05T01:03:42 < Steffanx> Avr has bascom :)

2019-01-05T01:04:30 < Steffanx> Good day englishman 
2019-01-05T01:04:46 < englishman> hi pops
2019-01-05T01:05:00 < englishman> i got a christmas card from belgium and thought it was from you
2019-01-05T01:05:05 < englishman> but alas, it was another chatter
2019-01-05T01:05:07 < Steffanx> Next time.
2019-01-05T01:05:14 < Steffanx> Ill try to not forget
2019-01-05T01:05:25 < tjq> I got a card from chinagirl
2019-01-05T01:05:33 < tjq> Not joking
2019-01-05T01:05:37 < Steffanx> Wut?
2019-01-05T01:05:42 < tjq> Yeah
2019-01-05T01:05:57 < tjq> All the chinagirls signed the card
2019-01-05T01:06:09 < Steffanx> you have a china girl?
2019-01-05T01:06:25 < tjq> Everyone does

2019-01-05T01:07:23 < Steffanx> catphish, wake up.
2019-01-05T01:07:33 < catphish> ahoyhoy
2019-01-05T01:08:01 < catphish> i'm not waking up unless someone can walk me through making my usb work
2019-01-05T01:08:07 < Steffanx> pass
2019-01-05T01:08:17 < catphish> Steffanx: did you want something?
2019-01-05T01:08:23 < tjq> Dr
2019-01-05T01:08:37 < BrainDamage> a couch to share intimate moments?
2019-01-05T01:08:52 < Steffanx> nah, if you dont understand its your loss, catphish
2019-01-05T01:09:40 < tjq> Boxing Day sales must have really fallen through. Still getting 5 emails a day
2019-01-05T01:09:51 < catphish> i have no idea what's going on
2019-01-05T01:10:10 < Steffanx> :P
2019-01-05T01:12:36 < tjq> 2019
2019-01-05T01:16:23 < englishman> 1) connect usb
2019-01-05T01:16:29 < englishman> 2) there is no 2, shit just works
2019-01-05T01:17:40 < BrainDamage> connect usb, negotiate isochronous transfer for low latency audio, see whole os to break down on missing samples
2019-01-05T01:17:50 < Steffanx> 1b) wrong way around mother fucker. Rotated connector.
2019-01-05T01:18:08 < Steffanx> *rotate
2019-01-05T01:18:22 < englishman> 1) connect ps/2
2019-01-05T01:18:25 < englishman> 2) boot computer
2019-01-05T01:20:44 < bitmask> sewing blows
2019-01-05T01:21:46 < Steffanx> dont you have a gf for that?
2019-01-05T01:22:27 < BrainDamage> get into cosplay as hobby, develop sewing skills
2019-01-05T01:22:48 < bitmask> she is doing most of it but I'm not gonna make her do everything
2019-01-05T01:23:12 < Steffanx> ah so there is still the gf :p
2019-01-05T01:23:18 < bitmask> spent $15 on a rayon/spandex blend :)
2019-01-05T01:23:27 < bitmask> of course :)
2019-01-05T01:23:35 < englishman> BrainDamage i ate a panettone
2019-01-05T01:23:48 < Steffanx> idk if that is "of course" since you raged a lot a while ago :P
2019-01-05T01:24:04 < BrainDamage> englishman: I hate them
2019-01-05T01:24:10 < englishman> same
2019-01-05T01:24:10 < BrainDamage> pandoro are so much better
2019-01-05T01:24:21 < bitmask> yea that was a bad time, i'm staying away from tha booze
2019-01-05T01:24:32 < tjq> did Laurence put on a show earlier
2019-01-05T01:24:51 < Steffanx> no
2019-01-05T01:25:36 < BrainDamage> englishman: https://en.wikipedia.org/wiki/Pandoro
2019-01-05T01:25:45 < BrainDamage> while not great, they are considerably better
2019-01-05T01:25:48 < englishman> imo if you are going to make sweet bread just make beer
2019-01-05T01:26:18 < englishman> i have enough frustra in my life tyvm
2019-01-05T01:26:40 < tjq> beer beer
2019-01-05T01:26:51 < zyp> I also need to get a sewing machine
2019-01-05T01:27:09 < tjq> hmm
2019-01-05T01:27:21 < Steffanx> uhm no?
2019-01-05T01:27:56 < BrainDamage> tbh I think the reason people eat them is just tradition
2019-01-05T01:28:14 < catphish> i just can't figure how how to get my usb up and running from the host side, i set up some stuff, nothing happens
2019-01-05T01:28:35 < zyp> apparently curtains only come in one length: «too fucking long so you can adjust them yourself to fit whatever»
2019-01-05T01:28:55 < Steffanx> did you turn it on catphish?
2019-01-05T01:29:05 < catphish> dunno, maybe
2019-01-05T01:29:23 < catphish> where's the power button
2019-01-05T01:29:30 < emeb> zyp: sewing machine is handy. someone who knows how to operate it is even better.
2019-01-05T01:30:00 < zyp> I used to know how, I hope I didn't forget
2019-01-05T01:30:02 < BrainDamage> it's not *that* hard
2019-01-05T01:30:06 < tjq> it's no longer legal to fly in slaveniggers
2019-01-05T01:30:14 < emeb> depends on what you're trying to do.
2019-01-05T01:30:34 < zyp> emeb, adjust the length of curtains
2019-01-05T01:31:01 < zyp> cut, fold, fold, sew, result largely depends on how accurate the folds are
2019-01-05T01:31:10 < emeb> zyp: same as hemming pants then.
2019-01-05T01:31:40 < zyp> yeah, I need to do that too
2019-01-05T01:32:20 < emeb> trick there is doing the hem stitch so it doesn't show from the outside.
2019-01-05T01:34:25 < ds2> fabric glue!
2019-01-05T01:34:59 < BrainDamage> just use cyanoacrylate
2019-01-05T01:35:03 < BrainDamage> on cotton it makes noxious vapours
2019-01-05T01:35:16 < BrainDamage> along an extremely exotermic reaction that can set on fire stuff
2019-01-05T01:36:07 < tjq> i'll brb
2019-01-05T01:36:24 < ds2> anyone ever figured a way to make a electrical connection to aluminum tape?
2019-01-05T01:37:28 < BrainDamage> sure, crimp it
2019-01-05T01:37:31 < upgrdman> ds2, a half-assed way might to be crimp a 0.1" contact onto it
2019-01-05T01:38:13 < BrainDamage> you can even solder it, BUT you'll need an HF based flux, something I don't recommend to breathe
2019-01-05T01:38:15 < ds2> that doesn't sound as half ass as using conductive epoxy or those carbon "conductive" glues
2019-01-05T01:38:34 < ds2> no HF. done the safety training, don't want to deal with it :D
2019-01-05T01:39:20 -!- upgrdman [~upgrdman@blender/artist/upgrdman] has quit [Quit: Leaving]
2019-01-05T01:40:01 < tjq> HF sounds evil
2019-01-05T01:40:35 < BrainDamage> aluminium passivation layer is resistant to most acids
2019-01-05T01:40:55 < BrainDamage> not even HCl will strip it
2019-01-05T01:41:14 < BrainDamage> you either need a strong base, or a stronger oxidizer than oxygen
2019-01-05T01:42:32 < ds2> what's stronger then oxygen?
2019-01-05T01:42:37 < BrainDamage> fluorine
2019-01-05T01:42:45 < BrainDamage> hence HF

2019-01-05T01:43:18 < ds2> is stronger oxidizer same as more electronegative?
2019-01-05T01:44:09 < tjq> is this the gear https://upload.wikimedia.org/wikipedia/commons/e/ef/Hydrogen_fluoride.JPG
2019-01-05T01:44:18 < emeb> why not use copper tape?
2019-01-05T01:44:21 < BrainDamage> in inorganic chemistry, yes, one implies the other
2019-01-05T01:44:48 < BrainDamage> tjq: at 40% it'll etch your lungs without even needing the soldering iron
2019-01-05T01:44:56 < tjq> hmmm tasty
2019-01-05T01:44:58 < ds2> $$$ trying to figure out the limits of my vinyl cutter and burnign through at roll of $1 alumimum tape is better then a $10 roll of copper tape 
2019-01-05T01:45:10 < tjq> the Wikipedia told me they use it to make prozac
2019-01-05T01:45:12 < tjq> interesting lol
2019-01-05T01:45:22 < ds2> <--- very rusty with redox chem
2019-01-05T01:45:26 < ds2> :D
2019-01-05T01:46:02 < BrainDamage> if you can get your hands on https://en.wikipedia.org/wiki/Chlorine_trifluoride you can oxidize almost everything
2019-01-05T01:46:11 < BrainDamage> including water, sand, asbestos, and ash
2019-01-05T01:47:07  * ds2 looks to see what will contain that
2019-01-05T01:47:18 < emeb> googling for "aluminum soldering" gives some interesting results
2019-01-05T01:47:41 < emeb> seems like the solder and flux are not hard to get and not super nasty
2019-01-05T01:47:45 < BrainDamage> I've heard some insane people scratch it under a layer of oil, then try to solder it
2019-01-05T01:47:57 < tjq> mmm nuclear reprocessing 
2019-01-05T01:48:10 < BrainDamage> emeb: what do they use as flux?
2019-01-05T01:48:24 < Steffanx> U-235 tjq
2019-01-05T01:48:31 < tjq> ah the good stuff?

2019-01-05T01:49:43 < ds2> that stuff doesn't eat glass
2019-01-05T01:50:54 < emeb> the msds has some odd stuff listed, but doesn't seem awful
2019-01-05T01:51:32 < ds2> awful as compared to what is found at a fab? :D
2019-01-05T01:51:39 < ds2> or a superfund site ?
2019-01-05T01:51:47 < emeb> awful as HF
2019-01-05T01:51:48 < BrainDamage> you might want a separate tip for that stuff
2019-01-05T01:51:55 < emeb> definitely

2019-01-05T02:09:59 < emeb> and there's the kinky bit
2019-01-05T02:10:09 < englishman> as the sap is sucked out at 30 inHg and everything needs to be attached and sealed
2019-01-05T02:10:36 < emeb> 30" is almost a hard vacuum, no?
2019-01-05T02:10:37 < Steffanx> its your kinky mind  emeb.
2019-01-05T02:10:46 < catphish> Steffanx: oh, yeah, that, well, see, now it's late and i don't really care any more :)
2019-01-05T02:10:48 < englishman> yeah maybe not 30 but i know they were doing 22 and moved up
2019-01-05T02:10:59 < catphish> maybe tomorrow
2019-01-05T02:11:10 < BrainDamage> 30inHg is 1 atm

2019-01-05T02:12:26 < catphish> i just realised the reason my usb doesn't work is probably because i'm trying to use usb 1 without first setting up usb 2.0, i think the relationship might be the reverse of what i thought it was

2019-01-05T17:19:55 < tomeaton17> not for personal stuff but for uni project its required

2019-01-05T17:20:06 < specing> why
2019-01-05T17:20:29 < tomeaton17> idk
2019-01-05T17:20:53 < tomeaton17> I can use what I want in 3rd year but not 2nd
2019-01-05T17:21:01 < englishman> if you make an legit argument to your profs about how much pic sucks cock they might be impressed and let you use better shit and give you a grade bump
2019-01-05T17:21:16 < englishman> or they could be dicks. either way
2019-01-05T17:21:29 < Steffanx> What pic is it me tomeaton17
2019-01-05T17:21:32 < Steffanx> Dspic?
2019-01-05T17:22:30 < Steffanx> Xmega.
2019-01-05T17:22:33 < specing> arms are not too complex
2019-01-05T17:22:44 < marble_visions> i can think of only two academic arguments for PICs
2019-01-05T17:22:56 < specing> the only difference with atmega is that you have to enable peripheral clocks and interrupt in NVIC
2019-01-05T17:23:05 < specing> at least for cortex-m0
2019-01-05T17:23:21 < specing> and PICs are awful due to paging

2019-01-05T17:23:44 < Steffanx> In assembly?
2019-01-05T17:23:51 < englishman> write your program directly in binary opcodes and submit that. tell them you are making it hard for them to grade because they are making it hard to develop

2019-01-05T17:26:30 < tomeaton17> dont think its public
2019-01-05T17:26:37 < tomeaton17> but I go to uni of manchester
2019-01-05T17:27:41 < jadew> given how the university is supposed to prepare you for life and how a lot of legacy shit is running PICs... maybe that's why
2019-01-05T17:28:01 < jadew> it's like learning C, when the world has C++
2019-01-05T17:28:06 < Steffanx> Thats not what a uni is for.

2019-01-05T17:31:29 < specing> jadew: it inherits all the bad things from C
2019-01-05T17:31:29 < jadew> you're attacking the language of choice for everything awesome
2019-01-05T17:31:36 < tomeaton17> make a basic calculator
2019-01-05T17:31:47 < tomeaton17> so basically just leds
2019-01-05T17:32:03 < specing> jadew: that is C++'s greatest weakness, it embeds C
2019-01-05T17:32:15 < jadew> specing, well, it's relatively backwards compatible with C, so... it inherits a lot
2019-01-05T17:32:16 < specing> and on microcontrollers C++ is often just "C with classes"
2019-01-05T17:32:44 < jadew> C with classes is better than C
2019-01-05T17:33:16 < marble_visions> ah, eee. well, good luck anyway

2019-01-05T17:46:34 < specing> stm has an appnote for a buck-boost, but they just assemble their own with discrete components
2019-01-05T17:47:09 < specing> I'm  open for fets, too :) Even more so if they have integrated drivers

2019-01-05T17:51:44 < specing> basically I want to play with SMPS, which means I need more flexibility than dedicated SMPS chips can provide
2019-01-05T17:52:28 < specing> well, the stm32 can certainly drive one, but problem is that it would take too long to overcome gate capacitance I guess

2019-01-05T22:12:28 < Steffanx> Didnt the son of the neighbour tell you? "T'es mort!".
2019-01-05T22:12:56 < mawk> lol
2019-01-05T22:13:15 < mawk> no he didn't say that, otherwise I'd have added death threat to the complaint
2019-01-05T22:13:31 < mawk> but I have threats of arson so it's nice too
2019-01-05T22:13:40 < MrMobius> mawk, do you upload your spreadsheets to your insurance company?
2019-01-05T22:13:49 < mawk> with a bit of luck he'll even get jailtime
2019-01-05T22:13:58 < mawk> I have no insurance MrMobius 
2019-01-05T22:14:08 < MrMobius> thats sucks
2019-01-05T22:14:13 < MrMobius> prolly shouldnt smoke then bro
2019-01-05T22:14:20 < mawk> I vape
2019-01-05T22:14:25 < mawk> to quit smoking
2019-01-05T22:14:31 < Steffanx> dont say the V-word!
2019-01-05T22:14:34 < mawk> lol
2019-01-05T22:14:37 < mawk> sorry
2019-01-05T22:14:42 < mawk> I was smoking around 30 rolled cigs a day
2019-01-05T22:14:47 < Steffanx> No insurance? Better not come to dutchland then. its mandatory.
2019-01-05T22:14:55 < mawk> here too
2019-01-05T22:14:58 < mawk> I'm illegal and stuff
2019-01-05T22:15:09 < mawk> then I was smoking like 5 cigs a day and *aping along, then I just quit the cigs
2019-01-05T22:15:10 < Steffanx> ah
2019-01-05T22:15:24 < Steffanx> there goes 130+ euro/month to the company and i get hardly anything for it.
2019-01-05T22:15:28 < mawk> well house insurance is mandatory
2019-01-05T22:15:31 < mawk> medical insurance isn't
2019-01-05T22:15:34 < mawk> but if you're poor enough it's free
2019-01-05T22:15:46 < mawk> but it's a shit insurance
2019-01-05T22:15:57 < mawk> for instance if you smash your teeth they pay for the ugly metal fake teeth, not the ceramic ones
2019-01-05T22:16:22 < MrMobius> mawk, do you live in a *-stan?
2019-01-05T22:16:35 < mawk> no, in France
2019-01-05T22:16:42 < mawk> but it's the same regime more or less

2019-01-05T22:21:07 < Steffanx> oh i read wireless, lol.
2019-01-05T22:21:17 < PaulFertser> mawk: seriously, when I needed to cover a broken tooth I tried to find more info on this topic and the conclusion was unambigous -- metal is the best.
2019-01-05T22:21:44 < invzim> I don't like the shiny plastic crappy logitech stuff
2019-01-05T22:22:11 < MrMobius> I saw a guy once with a fake ceramic tooth that was 3-4 teeth wide but they hadn't carved individual tooth shapes out of it
2019-01-05T22:22:14 < Steffanx> but its fucking hell ugly. At least when its one of the front teeth.
2019-01-05T22:22:22 < mawk> yeah PaulFertser 
2019-01-05T22:22:34 < mawk> I guess for durability it's the best
2019-01-05T22:22:46 < mawk> but in æsthetics it loses
2019-01-05T22:23:12 < PaulFertser> I have two 2nd pre-molars covered with metal, not the front teeth, I admit.
2019-01-05T22:23:52 < Steffanx> why do you break them in the first place?
2019-01-05T22:24:25 < PaulFertser> No particular reason, they just eventually broke.

2019-01-05T23:33:41 < mawk> if I acquire a gun that shoots gum balls can I bring it to the netherlands
2019-01-05T23:33:55 < mawk> here to acquire it I need to get reviewed by a psychiatrist that testifies I'm not insane, then register the gun with the police headquarters
2019-01-05T23:34:16 < mawk> if it's a real gun I need to be a hunter with a permit, to do sportive shooting like ball-trap, or be a policeman

2019-01-05T23:40:48 < Steffanx> Real guns require a permit. Idk how to get one

2019-01-05T23:44:15 < mawk> well it's a real gun
2019-01-05T23:44:20 < mawk> but it shoots only gum balls
2019-01-05T23:44:26 < mawk> but with gunpowder
2019-01-05T23:44:44 < mawk> and knowing that france is very restrictive in its weapon legislation I wouldn't be surprised if the NLs allowed a bit more
2019-01-05T23:45:04 < Ecco> hi :)
2019-01-05T23:45:06 < mawk> also it's maybe legal to own something that looks like a gun here but if you use it to point to someone it's the exact same sentence as if it were a real loaded gun
2019-01-05T23:45:08 < mawk> hi Ecco 
2019-01-05T23:45:36 < Ecco> Dumb STM32 question: how slow can the CPU be slowed down?
2019-01-05T23:45:47 < Ecco> I'm asking because I'm randomling reading an F7's datasheet
2019-01-05T23:46:03 < Ecco> and they give power usage for a range of frequencies, between 25 and 216 MHz
2019-01-05T23:46:10 < mawk> that depends on the cpu I guess
2019-01-05T23:46:18 < Ecco> I'm wondering why it doesn't go much lower
2019-01-05T23:46:20 < mawk> inside cubemx you can play with the clocks and it says
2019-01-05T23:46:30 < Ecco> oh, great, thanks, I'll give that a try
2019-01-05T23:46:39 < mawk> but it should be said in the datasheet
2019-01-05T23:46:49 < mawk> I just brought up cubemx in case you have it at hand
2019-01-05T23:47:10 < Ecco> I do
2019-01-05T23:48:06 < Steffanx> I think its a no-go then mawk. Because gun powder
2019-01-05T23:49:12 < mawk> lame
2019-01-05T23:49:22 < mawk> so even guns that shoot blanks aren't authorized ?
2019-01-05T23:49:26 < mawk> sounds more restrictive than France
2019-01-05T23:49:52 < mawk> I'll make it illegally enter the country
2019-01-05T23:49:58 < mawk> throwing it above the border
2019-01-05T23:52:36 < Steffanx> I bet you can just drive it over.
2019-01-05T23:53:18 < Steffanx> Unless you have a suspicious looking face.
2019-01-05T23:54:17 < zyp> Ecco, I don't think the cpu itself has any lower limit, but the oscillators do
2019-01-05T23:54:48 < zyp> I guess if you feed it an internal clock from somewhere, you could probably run it at kHz if you wanted to
2019-01-05T23:54:58 < zyp> or perhaps less? :)
2019-01-05T23:55:03 < zyp> external*
2019-01-05T23:55:50 < mawk> NL law says "People with felonies, drug addictions, and mental illnesses may not possess firearms."
2019-01-05T23:55:51 < mawk> :(
2019-01-05T23:55:55 < mawk> that's discrimination !
2019-01-05T23:56:08 < Steffanx> Racism!
2019-01-05T23:58:06 < mawk> maybe they don't count former addiction and support treatments as addiction
2019-01-05T23:58:11 < specing> that is all fun and games until Hitler invades and nobody can defend (and does not know how to handle a firearm even if issued one by state 1h prior)
2019-01-05T23:58:30 < specing> best plan for defending your country in europe is to run the other way
2019-01-05T23:59:28 < Steffanx> You sounds like r2com now specing. Are you sure you want that?

2019-01-06T00:00:00 < Ecco> zyp: interesting :)
2019-01-06T00:00:06 < Ecco> Is the power usage proportional to the frequency?
2019-01-06T00:00:07 < Steffanx> If its not internationally registered and you lie about it mawk...
2019-01-06T00:00:20 < specing> I'm just stating facts and would be more than happy if we could all return to topic
2019-01-06T00:00:29 < Ecco> If yes, then why bother with a sleep mode at all (instead one could just run the CPU very slowly)
2019-01-06T00:00:37 < specing> and I don't know who r2com is
2019-01-06T00:01:03 < mawk> yeah Steffanx 
2019-01-06T00:12:34 < Steffanx> Lol specing
2019-01-06T00:13:08 < mawk> you can't run it too slow Ecco 
2019-01-06T00:13:13 < mawk> also sleep mode saves more power

2019-01-06T00:24:07 < zyp> Ecco, you may
2019-01-06T00:24:24 < zyp> Ecco, for some applications that might be beneficial
2019-01-06T00:24:42 < zyp> for other applications, you save more power by completing computations quickly and then going to sleep
2019-01-06T00:24:58 < zyp> and the latter scales better with dynamic loads
2019-01-06T00:25:09 < zyp> if you have more work to do, you just spend less time asleep
2019-01-06T00:26:11 < tjq> Sleeping cat
2019-01-06T00:26:24 < zyp> if a reduced speed strategy is gonna work, you need to find the right speed to complete work on time without spending a lot of time idle
2019-01-06T00:26:35 < zyp> that can be hard to predict
2019-01-06T00:27:13 < zyp> but it might be beneficial if you have light work that needs to be performed at really short intervals
2019-01-06T00:27:18 < specing> I don't think you save power by using lower frequency
2019-01-06T00:27:29 < zyp> of course you do
2019-01-06T00:27:42 < specing> the switches are designed for some switching speed and that is independent of clock frequency
2019-01-06T00:27:54 < specing> there are just less switches per second
2019-01-06T00:27:59 < zyp> digital electronics 101: power is largely consumed during switching
2019-01-06T00:28:12 < specing> but you still need the same amount of switches to do the same work
2019-01-06T00:28:19 < specing> you just do it more slowly
2019-01-06T00:28:27 < zyp> yes
2019-01-06T00:29:09 < specing> maybe it would matter on F7 or something where the branch predictor/RAM access clock latency increases with frequency
2019-01-06T00:29:13 < zyp> the question here is whether you're looking at energy vs time or energy vs work
2019-01-06T00:29:17 < specing> but not on 48 MHz M0
2019-01-06T00:29:54 < specing> energy vs time? Only if your psu is power constrained?
2019-01-06T00:30:03 < specing> e.g. if you are running from alkaleak coin cells
2019-01-06T00:30:27 < zyp> you're missing parts of the picture
2019-01-06T00:30:50 < zyp> if you're looking only at energy vs work, you're leaving out what to do when you're idle
2019-01-06T00:31:06 < specing> nothing, you wait for more work
2019-01-06T00:31:36 < zyp> yes, and the question here is how to do nothing consuming the least amount of energy
2019-01-06T00:31:49 < zyp> this is where the two strategies differ
2019-01-06T00:32:12 < zyp> either you go to sleep in a low power state
2019-01-06T00:32:32 < zyp> or in the other case, you tune the cpu clock so you minimize the time spent idle
2019-01-06T00:33:20 < zyp> going to sleep and waking up is not entirely free, so you'd want to spend enough time asleep to make it worthwhile
2019-01-06T00:33:57 < zyp> if you have light but very frequent work, a reduced speed strategy might end up more efficient overall
2019-01-06T00:35:35 < zyp> however, I'd argue that those would be special cases and you should only consider that when you're power optimizing at a late stage in the project
2019-01-06T00:37:43 < specing> Yes

2019-01-06T01:36:45 < karlp> it's less important now that I've moved the desk out of the bedroom, maybe I should dig up the das keyboard again....
2019-01-06T01:36:55  * karlp wonders why he didn't think of that earlier
2019-01-06T01:37:00 < jadew> the browns are quiet
2019-01-06T01:37:18 < jadew> (no click, other than bottoming out the key)
2019-01-06T01:37:22 < karlp> invzim: if it's just about the travel, the that one I linked is ~same as any normal generic keyboard, just wireless instead of wired.
2019-01-06T01:38:13 < jadew> karlp, maybe it was a shipping mistake and they gave you the wrong version?
2019-01-06T01:39:30 < karlp> no, they're brown.
2019-01-06T01:39:35 < karlp> I had to pu tmy own key caps on them
2019-01-06T01:39:42 < karlp> and it's definitely quieter than blues I've tried,
2019-01-06T01:40:04 < karlp> it's just that "quiet for a desk beside a bed" is not what many people seem to think is "quiet"
2019-01-06T01:40:32 < jadew> ah, yeah, it's not entirely quiet
2019-01-06T01:40:39 < karlp> I feel like people think "quiet" just means, "it's not like a model-m"
2019-01-06T01:40:49 < karlp> which is .... true, but not exactly quiet :)
2019-01-06T01:40:56 < jadew> I don't know how it sounds with the dampners, but if it completely eliminates the bottoming out sound, then they should be fairly quiet
2019-01-06T01:41:03 < karlp> it doesn't.
2019-01-06T01:41:11 < karlp> and it doesn't type as nicely afterwards either
2019-01-06T01:41:39 < karlp> anywya, as said, moved the desk, can make noise again really :)
2019-01-06T01:41:48 < jadew> this is me typing regularly: http://86.121.138.15/stuff/Recording.m4a
2019-01-06T01:41:52 < jadew> (no dampners)
2019-01-06T01:42:11 < jadew> you can even hear the click of the switches - I could sleep on that
2019-01-06T01:42:20 < karlp> yeah, I don't really get how people thnk audio recordings are useful indicators of "noise" but thanks for trying :)
2019-01-06T01:42:54 < jadew> you can at least compare with yours
2019-01-06T01:43:03 < jadew> if the sound is similar
2019-01-06T01:44:19 < karlp> how are we meant to normalise our volumes?
2019-01-06T01:44:23 < jadew> when I got the M out and tried it for a few minutes, my wife came in and said something like "I hope you're not planning to use that now..."
2019-01-06T01:44:57 < jadew> you want me to say something?
2019-01-06T01:45:26 < karlp> I have no reference for what you sound like :) this is why I think it's so funny :)
2019-01-06T01:45:34 < karlp> I do appreciate the effort, but just relax, do something else :)
2019-01-06T01:45:55  * jadew deletes recording
2019-01-06T01:45:58 < karlp> I'm about to pig out eating the last of the christmas pig, the last of my dutch cheese, and some good icelandic beer, and play video games :)
2019-01-06T01:46:16 < Steffanx> its sleep o clock. :P
2019-01-06T01:46:17 < karlp> and I'm guessing probbly kenyan snow peas
2019-01-06T01:46:25 < karlp> no, my time.
2019-01-06T01:46:30 < BrainDamage> no christmas beer?
2019-01-06T01:46:37 < karlp> I got up this morning, and we've done two christmas parties and a birthday party today
2019-01-06T01:46:40 < karlp> I get to sleep in tomorrow
2019-01-06T01:46:55 < karlp> BrainDamage: have a few, but have to keep them as presents for my brother in amonth in aus

2019-01-06T01:47:50 < karlp> we'll have big bonfires and fireworks tomorrow too
2019-01-06T01:48:02 < Steffanx> 12th night, never heard of that
2019-01-06T01:48:15 < karlp> and both these parties were for extended families to meet up avoiding all the _other_ christmas parties around christmas itself.
2019-01-06T01:48:32 < BrainDamage> here xmas time ends with the epiphany
2019-01-06T01:48:32 < karlp> Steffanx: we've got 13 santa clauses, leaving one by one, one night at a time. it takes a while
2019-01-06T01:49:20 < karlp> BrainDamage: yeah, that's what I'm talking about
2019-01-06T01:49:28 < karlp> we call it "thirteenth"
2019-01-06T01:49:35 < jadew> didn't know christmas takes so long
2019-01-06T01:49:36 < karlp> in english it's often 12th night.
2019-01-06T01:49:41 < Steffanx> epiphany, we dont do that here.
2019-01-06T01:49:51 < jadew> in here it takes only 3 days IIRC
2019-01-06T01:49:58 < karlp> we sure as fuck don't go to church :) but the date is still significant
2019-01-06T01:50:03 < jadew> but people only seem to care about the first 2
2019-01-06T01:50:30 < jadew> well, it's the christmas eve, the christmas day and the second day of christmas
2019-01-06T01:50:36 < jadew> and then everyone goes back to work
2019-01-06T01:51:09 < jadew> oh wait, we have that day too
2019-01-06T01:51:29 < Steffanx> afaik we dont. we gave up on our catholic roots i guess
2019-01-06T01:51:34 < jadew> and yeah, it's important, I just didn't know it's related to christmas
2019-01-06T01:51:56 < jadew> it's called the baptism day
2019-01-06T02:08:33 < tjq> We’ll check around here ok
2019-01-06T02:11:03 < Steffanx> there is no piece of crt here, sorry.

2019-01-06T03:22:21 < jadew> jeez, that last link you posted set me on a course of self discovery
2019-01-06T03:22:39 < jadew> and self-betterment
2019-01-06T03:23:54 < jadew> that room is probably a masturbatorium, like that second comment points out, but it's also the room of someone who gave in a little too much to his silly pleasures
2019-01-06T03:24:21 < jadew> it's also a room where nothing productive happens
2019-01-06T03:25:09 < jadew> not because the shit there is not useful (which I'm sure it isn't) but because of how that shit got there - it's not there with a purpose, but to satisfy a desire
2019-01-06T03:26:08 < jadew> makes you think about your own lair, isn't it?
2019-01-06T03:26:43 < jadew> and if this is not visible around you, it may be visible on your PC
2019-01-06T03:27:26 < BrainDamage> you're overanalyizing it, it's not like there's a single explanation, the anime crap and the posters can be misguided attempts to make the room more humane / comfortable
2019-01-06T03:27:31 < jadew> I think it's probably a good thing to keep in mind and try to distance yourself from if you decide to lead a productive life
2019-01-06T03:27:58 < BrainDamage> instead of painting the walls and have a proper lighting and degree of cleaniness
2019-01-06T03:28:09 < BrainDamage> however, if it's rented, painting may not be possible
2019-01-06T03:28:10 < jadew> BrainDamage, their existence alone is an offence
2019-01-06T03:28:24 < BrainDamage> you get offended too easily then
2019-01-06T03:28:33 < jadew> it's not offending me
2019-01-06T03:28:42 < jadew> it's bad for the guy
2019-01-06T03:28:50 < Steffanx> guy?
2019-01-06T03:28:54 < jadew> I get one or two, but that many it's just nuts
2019-01-06T03:29:11 < jadew> Steffanx, ze?
2019-01-06T03:29:17 < jadew> xe?
2019-01-06T03:29:33 < BrainDamage> so you're acting offended, you say it's offence, but it's not offending you?
2019-01-06T03:29:58 < jadew> I'm not offended, I'm exilerated for realizing this
2019-01-06T03:30:03 < Steffanx> jadew, ye
2019-01-06T03:30:09 < jadew> because I can now correct that sort of crap in my own life

2019-01-06T03:32:22 < jadew> yeah, because when it's my own mess, I don't recognize the insanity
2019-01-06T03:33:36 < Steffanx> did you know blaxter is long gone?
2019-01-06T03:33:49 < jadew> I'm sure that's not his room
2019-01-06T03:34:08 < jadew> I was just sharing my little epiphany
2019-01-06T03:35:01 < jadew> wish I had a picture of my lab a week ago
2019-01-06T03:35:05 < jadew> it looked a lot like that
2019-01-06T03:43:05 < jadew> the question that raises into my mind is if everything in my lab is a product of my insanity or if it has a good reason for being here
2019-01-06T03:45:21 < jadew> I have a few items that shouldn't be here, because I wanted to do something with them and then I didn't
2019-01-06T03:45:53 < jadew> even tho, I didn't give up on those ideas, something else took precedence
2019-01-06T03:46:17 < jadew> and that's how you end up with a room full of dolls...
2019-01-06T03:48:02 < jadew> I guess the cure for this is to refuse to start something else until you finish the previous project
2019-01-06T03:48:57 < jadew> which is difficult, because there are delays that force you to take on multiple projects at the same time (for example waiting for PCBs)
2019-01-06T03:49:39 < englishman> you could take up a hobby that you can stop and start whenever, like smoking drugs
2019-01-06T03:49:48 < jadew> haha

2019-01-06T18:17:32 < jpa-> Sadale: most embedded code is just portable C, you can test it on PC easily enough
2019-01-06T18:18:00 < Sadale> hmm. true.
2019-01-06T18:18:12 < jpa-> and setting up tests to run automatically on real hardware is not difficult either, though i rarely bother
2019-01-06T18:18:14 < Sadale> But wouldn't stuffs like the size of datatype comes into the play?
2019-01-06T18:18:38 < jpa-> yeah, but you can compile code as 32-bit x86 and it is pretty much the same as 32-bit arm
2019-01-06T18:18:47 < Sadale> true.

2019-01-06T18:19:23 < Sadale> Unit tests are probably easy. What about integration tests?
2019-01-06T18:19:50 < jpa-> yeah, that's where it gets annoying
2019-01-06T18:19:54 < Sadale> For example, if the device requires interacting with sensor, would you automate the integration tests somehow, like reading the data from sensor and ensure that the data read is correct.
2019-01-06T18:20:25 < BrainDamage> the latter is harder
2019-01-06T18:20:28 < Sadale> I'm just curious if it's a thing in embedded programming world. That's because test automation seems to be a big thing in higher level software development.
2019-01-06T18:20:36 < BrainDamage> unless the sensor has a test mode, you cannot ensure a consistent read
2019-01-06T18:20:41 < Sadale> true.
2019-01-06T18:21:00 < jpa-> automatic testing is always a tradeoff, not everything is worth testing automatically
2019-01-06T18:21:13 < Sadale> perhaps manipulating the environment could work. But that'd be a lot of efforts to do that, depending on the kind of sensor.
2019-01-06T18:21:25 < Sadale> jpa-, agreed.
2019-01-06T18:21:32 < BrainDamage> englishman: there's a non-akronym bold text in the 2nd to last page
2019-01-06T18:21:49 < jpa-> i've found that what works best is developing robust portable libraries and unittest them on PC, and then do the integration testing on embedded system manually
2019-01-06T18:22:40 < jpa-> e.g. a sensor driver, you write it once, test it, no need to run full test again unless you change the driver
2019-01-06T18:22:46 < Sadale> true. :)
2019-01-06T18:22:53 < jpa-> if it breaks due to some other change in system, a simple smoke test should catch it

2019-01-06T18:34:13 < mawk> now I will go to heaven I hope
2019-01-06T18:35:00 < mawk> BrainDamage: because it's not the sensor you're testing can't you just fake the data the sensor is returning ?
2019-01-06T18:35:22 < BrainDamage> you're testing everything
2019-01-06T18:35:39 < BrainDamage> the hardware link layer and the protocol
2019-01-06T18:36:00 < mawk> then faking the sensor with an external fake sensor ?
2019-01-06T18:36:36 < BrainDamage> sure, it boils then to amount of efforts
2019-01-06T18:36:50 < BrainDamage> also, testing the protocol doesn't strictly requires the hw
2019-01-06T18:37:04 < jpa-> then you are just testing that driver works with fake sensor, which is not necessarily very useful
2019-01-06T18:37:22 < BrainDamage> as long as the hw adheres to the protocol without bugs and it's perfectly specified
2019-01-06T18:37:30 < BrainDamage> however, reality isn't always that nice
2019-01-06T18:37:47 < jpa-> the most difficult bugs to find are stuff like "sensor doesn't lock register updates in this particular situation, causing half-corrupted reads of 16-bit registers very rarely"

2019-01-06T19:12:34 < Sadale> true. But that can be problematic if the code is intended to be used for multiple different microcontrollers.
2019-01-06T19:12:56 < Sadale> I meant, it would work perfectly probably. But there can be performance hit.
2019-01-06T19:14:26 < specing> you can check the disassembly if the compiler inserted additional checks and adjust code so these situations cannot arise
2019-01-06T19:14:59 < specing> and no, it is not problematic when the code is used for multiple mcus
2019-01-06T19:15:20 < specing> you tell the compiler how many bits and/or the range you need and it will make sure this happens or error out
2019-01-06T19:18:44 < specing> I'm pretty sure people all the time rely on int holding really big values, even though the standards usually only guarantee int being at least 16 bit

2019-01-06T20:24:27 < Laurenceb_123> I suspect the hardware is capable of doing that

2019-01-06T22:07:56 < superbia> can you imagine this type of a thing
2019-01-06T22:08:23 < superbia> can you rip the black thing on the pins ?
2019-01-06T22:08:32 < Steffanx> Sure.
2019-01-06T22:08:34 < superbia> with pliers or something
2019-01-06T22:09:20 < superbia> do you first use cutters to separate each 'block of plastic' and then use pliers to take out each link ?
2019-01-06T22:09:32 < superbia> or do you like wiggle everything with pliers ?
2019-01-06T22:09:50 < Steffanx> i never do that, but i would probably cut it down into smaller blocks.
2019-01-06T22:09:58 < Steffanx> or maybe melt them off. :P
2019-01-06T22:10:06 < superbia> the fuck is that it's already soldered to my micro
2019-01-06T22:10:35 < superbia> and for some fucking reason, i need to remove the fucking black plastic (because americans designed my pcb)
2019-01-06T22:10:42 < Steffanx> Or you just desolder the pins and put new in.
2019-01-06T22:10:51 < superbia> see

2019-01-06T22:11:11 < Steffanx>  Ask stvn.
2019-01-06T22:11:46 < Steffanx> Are you sure they removed the plastic here? and its not just longer pins with the plastic stuff on the other side?
2019-01-06T22:11:53 < Steffanx> or is this your photo? :D
2019-01-06T22:12:05 < superbia> fuck

2019-01-06T22:12:44 < Steffanx> ah, awesome.
2019-01-06T22:12:52 < superbia> they removed plastic on the other side
2019-01-06T22:13:09 < superbia> right ?
2019-01-06T22:13:48 < superbia> and they cut the extra pin length
2019-01-06T22:13:59 < Steffanx> idk..
2019-01-06T22:14:56 < BrainDamage> that logo is what pharmacies have here
2019-01-06T22:15:13 < Steffanx> You can always heat up a scapel a bit, cut the blocks and pull them of.
2019-01-06T22:15:46 < Steffanx> or ask BrainDamage. He always has good ideas
2019-01-06T22:15:57 < BrainDamage> since when

2019-01-06T22:18:51 < BrainDamage> you don't strictly need a desoldering pump
2019-01-06T22:18:59 < BrainDamage> cut the strips first

2019-01-06T23:06:27 < mawk> it's a special kind of exam, they don't want us to bring down the school statistics so they allow us to have any kind of documentation with us

2019-01-06T23:07:20 < mawk> so I took the CAN bus presentation, make it 2×2 slides on a single page, removed the background images, put it in black and white, and printed it on both sides of the paper; now it's only 100 pages

2019-01-06T23:27:12 < mawk> yeah and that teacher takes pride in writing the less english possible
2019-01-06T23:27:28 < mawk> otherwise "trame avec bits de bourrage" would have been something like "trames avec bits de padding"
2019-01-06T23:29:40 < mawk> in advertising yes
2019-01-06T23:29:44 < mawk> but in other domains no

2019-01-06T23:31:48 < mawk> bourrage is like stuffing

2019-01-06T23:32:26 < mawk> I guess
2019-01-06T23:32:32 < mawk> that's how I'd translate padding
2019-01-06T23:32:40 < mawk> but I never translate it, I just say padding
2019-01-06T23:32:52 < BrainDamage> il ete ne pas gras, cette sons gross os
2019-01-06T23:33:02 < BrainDamage> damn my french is rusty
2019-01-06T23:33:05 < mawk> lol
2019-01-06T23:33:11 < mawk> sounds like a line from asterix
2019-01-06T23:33:22 < mawk> je ne suis pas gras, j'ai juste de gros os
2019-01-06T23:34:44 < mawk> you speak better french than I could speak italian or spanish BrainDamage 
2019-01-06T23:34:56 < mawk> you speak french like I speak german, maybe
2019-01-06T23:35:06 < mawk> the two grammars are equally horrible
2019-01-06T23:36:41 < mawk> I think he meant "il n'est pas gras, ce sont ses os qui sont gros"
2019-01-06T23:37:00 < mawk> or in toddler french, which looks more like english, "il est pas gras, ce sont ses os"
2019-01-06T23:37:33 < mawk> word to word translation would be "he is not fat, it is his bones"
2019-01-06T23:37:47 < mawk> it's just a simple negation
2019-01-06T23:37:51 < mawk> il n'est pas
2019-01-06T23:37:54 < mawk> "pas" is the negation
2019-01-06T23:38:02 < mawk> and n'/ne is just to speak the higher french
2019-01-06T23:38:04 < mawk> but you can omit it
2019-01-06T23:38:14 < mawk> yeah I guess it could look like a double negation
2019-01-06T23:38:19 < mawk> but it's just for speaking the one true french
2019-01-06T23:39:40 < mawk> you have roughly three levels of language, and only in the highest you add the n'/ne
2019-01-06T23:41:06 < mawk> lol
2019-01-06T23:41:21 < mawk> toddler french is my translation of "petit nègre", which means "speaking like a little nigger"
2019-01-06T23:41:42 < mawk> but curiously no antiracist association has banned this expression yet
2019-01-06T23:41:48 < mawk> but they banned the "tête de nègre" pastry
2019-01-06T23:42:29 < mawk> petit nègre is like broken french with no grammar, etc
2019-01-06T23:43:16 < Steffanx> What does the low class french say? They just skip the "ne"?
2019-01-06T23:43:22 < mawk> yeah
2019-01-06T23:43:26 < Steffanx> Je ne parle pas français? 
2019-01-06T23:43:37 < mawk> yeah, that becomes "je parle pas français"

2019-01-06T23:43:44 < mawk> it's like casual talk
2019-01-06T23:43:57 < mawk> you use the ne and proper inversion of words in questions in the higher form
2019-01-06T23:44:11 < mawk> otherwise you just drop the ne from negations, and just slam a ? at the end if you want to make a question
2019-01-06T23:44:37 < mawk> eg "we are we going ?" would be "où allons-nous ?" in higher form, and "on va où ?" in casual form
2019-01-06T23:45:00 < mawk> "where are we going ?" * sorry
2019-01-06T23:46:02 < mawk> everything is conjugated
2019-01-06T23:46:13 < mawk> you can't not conjugate verb, otherwise you're speaking petit-nègre
2019-01-06T23:46:33 < mawk> it's just that in higher form you say "nous" for "us", but in casual form you say "on", which is like "man" in english
2019-01-06T23:46:38 < mawk> like "one" in english sorry
2019-01-06T23:46:42 < mawk> and like "man" in german
2019-01-06T23:47:03 < mawk> so it's just a different conjugation of the aller verbe, on va, nous allons
2019-01-06T23:47:55 < mawk> lol
2019-01-06T23:47:58 < mawk> yeah I can feel that
2019-01-06T23:48:09 < mawk> I was bad in german and in latin because of all the conjugations

2019-01-06T23:55:40 < mawk> or something like this

2019-01-06T23:56:37 < mawk> when I did my first network internship I was just parachuted like this in the new company offices, on my own on a weekend, with hundreds of meters of ethernet cables, brand new switches, a router, a fiber arrival, and my computer; and nobody to help me
2019-01-06T23:56:38 < zyp> but I managed to fit one cat6 and one cat5e
2019-01-06T23:56:41 < mawk> ah, nice
2019-01-06T23:58:00 < zyp> cat5e is probably plenty anyway, I'll also be running fiber to all the points that are likely to see anything >1G
2019-01-06T23:58:16 < mawk> isn't there a 10G standard for ethernet ?
2019-01-06T23:58:21 < mawk> or that's fiber only above 1Gbps
2019-01-06T23:58:27 < zyp> there is
2019-01-06T23:58:34 < zyp> but fiber is cheaper
2019-01-06T23:58:38 < mawk> I see
2019-01-06T23:58:45 < zyp> at least for now
2019-01-06T23:59:04 < zyp> and when that changes, I also have one cat6 to each point
--- Day changed Mon Jan 07 2019
2019-01-07T00:00:03 < mawk> why two links ? for aggregation ?
2019-01-07T00:00:11 < mawk> VLANs aren't enough ?
2019-01-07T00:00:18 < zyp> nah
2019-01-07T00:00:27 < zyp> just in case
2019-01-07T00:01:12 < zyp> maybe I wanna have two devices somewhere, saves a switch
2019-01-07T00:01:22 < mawk> yeah
2019-01-07T00:01:23 < zyp> maybe I wanna run something other than ethernet on one cable
2019-01-07T00:01:28 < zyp> etc…
2019-01-07T00:02:56 < zyp> I figure I'll have the network closet running from UPS, PoE switch in there, then all PoE powered devices around the house will keep working in a power outage
2019-01-07T00:05:32 < zyp> put another way, I'll rather put it in and not need it than not put it in and need it
2019-01-07T00:10:54 < Steffanx> Ah fancy, zyp.
2019-01-07T00:11:06 < Steffanx> Better get a knife or scissors for the tape next time :P
2019-01-07T00:11:38 < zyp> why?
2019-01-07T00:12:29 < Steffanx> pulling (and stretching) it is so ugly :P
2019-01-07T00:16:18 < Steffanx> no fibre in there btw? or is that on the todo list?
2019-01-07T00:18:11 < qyx> zand whats the orange cable?
2019-01-07T00:19:40 < Steffanx> looks like some kind of fish tape to me.
2019-01-07T00:19:44 < Steffanx> or whatever you call that in english
2019-01-07T00:27:51 < englishman> exactly that
2019-01-07T00:28:46 < englishman> leaving out ne/n' isn't lower class french it's stupid and redundant
2019-01-07T00:30:04 < englishman> i do like that french has an alternative to 'yes' when responding to a question asked in the negative
2019-01-07T00:30:57 < BrainDamage> you have an alternative in many languages
2019-01-07T00:31:09 < BrainDamage> you can eg say "correct"

2019-01-07T00:41:33 < mawk> sì
2019-01-07T00:42:19 < mawk> if you leave out "ne" when talking to a CEO, to the parliament, to fancy dinners, etc, they'll think you're poor and uneducated englishman 
2019-01-07T00:42:45 < BrainDamage> you're a poor and uneducated englishman*

2019-01-07T01:06:04 < aandrew> all my USB stuff is working, except transmitting back to the PC
2019-01-07T01:06:26 < aandrew> I receive perfectly fine, and my setup for TX looks correct (sending to EP 0x81, buffer is right, length is right, etc.)
2019-01-07T01:06:43 < aandrew> but when it actually starts to transmit, I get a USB IRQ (naturally) and then enver recover
2019-01-07T01:07:06 < aandrew> it's like the data in (to pc) stage isn't being handled correctly
2019-01-07T01:07:46 < aandrew> USB_OTG_GINTSTS_IEPINT is in endpoint interrupt I am guessing
2019-01-07T01:07:48 < aandrew> which is right
2019-01-07T01:08:22 < aandrew> ep_intr is 0x02 though which doesn't sound right... shouldn't it be 1 for EP 0x81?
2019-01-07T01:08:51 < aandrew> 0x81 is my to-the-pc endpoint, 0x02 is my from-the-pc endpoint
2019-01-07T01:10:41 < aandrew> er no ep_intr isn't that, it's something else

2019-01-07T01:47:49 < zyp> which then?
2019-01-07T01:47:52 < Steffanx> i think us international whatever, is more standard in dutchland

2019-01-07T01:50:03 < zyp> but yeah, just using the us layout makes sense if your language doesn't use any uncommon letters or anything
2019-01-07T01:50:07 < Steffanx> oh, and perhaps that boring.
2019-01-07T01:51:00 < Steffanx> as long as its not Æ/Ø etc. or this circle on an aoie etc., i can do it.
2019-01-07T01:51:15 < BrainDamage> I use the us layout
2019-01-07T01:51:24 < BrainDamage> altough the single row enter weirds me out
2019-01-07T01:51:27 < zyp> to me it'd be unnatural to use a keyboard without ÆØÅ, but apart from those and habit I don't have any particular reason to use the norwegian layout
2019-01-07T01:53:10 < Steffanx> we mainly use é or è to emphasize stuff. umlauts(fuck why we also call it an umlaut, i dont know the english term) are more common.
2019-01-07T01:53:17 < Steffanx> i blame the germans for that.. umlaut.
2019-01-07T01:53:34 < zyp> aren't they called umlaut in english?
2019-01-07T01:53:44 < Steffanx> idk.

2019-01-07T02:31:10 < munki_>  hey all
2019-01-07T02:31:10 < munki_>  if i wanted to do a project that required a uC to drive a pretty high res screen
2019-01-07T02:31:10 < munki_>  id' need a good amount of ram right
2019-01-07T02:31:10 < munki_>  what are uC's with large quantities of RAM available, or maybe what are good resources to learn about how to use external RAM chips
2019-01-07T02:31:10 < munki_>  like an 800x480 screen, assuming 1 byte per pixel, that's 384k of ram just for a single screen buffer
2019-01-07T02:31:10 < munki_>  though i guess reducing the pallet size to something like
2019-01-07T02:31:20  * karlp laughs
2019-01-07T02:31:21 < munki_>  24 colors that would substantialy reduce ram usage
2019-01-07T02:31:27 < karlp> the "hey all" was particularly redundant
2019-01-07T02:31:56 < karlp> you can also get screen controllers that take care of some of this for you...
2019-01-07T02:32:11 < munki_> true
2019-01-07T02:32:29 < munki_> trying to keep board complexity down but that would be a useful thing to consider i agree
2019-01-07T02:32:51 < munki_> having external ram would however increase board copmlexity in and of itself so that's a moot point most likely
2019-01-07T02:33:36 < karlp> ask another way, what do you need a MCU on this for at all?
2019-01-07T02:33:57 < karlp> have you considered a more regular embedded linux solution instead?
2019-01-07T02:34:05 < munki_> the goal is to have some sort of files on an SD card, and read from them, to display on the screen
2019-01-07T02:34:28 < karlp> you can probably by that as a single chip solution, given the old prevalance of picture frame shitz
2019-01-07T02:34:37 < munki_> i figured having a lunix solution would be substantially more complex to create a board for and mfg
2019-01-07T02:34:48 < munki_> let alone program and develop
2019-01-07T02:34:51 < karlp> did you actually investigate?
2019-01-07T02:35:02 < munki_> like look at how complex an rpi is 
2019-01-07T02:35:15 < karlp> have you ever heard of a module?
2019-01-07T02:35:26 < munki_> compared to seomething like a gen4-iod-24t esp8266 screen board

2019-01-07T02:37:16 < karlp> though honestly, that 4d system is way chaper than older 4d stuff, just use it and move on
2019-01-07T02:37:33 < munki_> too low resolution, i used it for this year's iteration and for next year i'd like to have soething substantially higher res
2019-01-07T02:37:48  * karlp laughs
2019-01-07T02:38:11 < munki_> that's not very nice sir
2019-01-07T02:38:22 < munki_> sorry if i offended you
2019-01-07T02:44:33 < Steffanx> Isnt an rpi + dsi display cheap enough. Certainly < 100 dollwr
2019-01-07T02:45:25 < Steffanx> There are some stm32 discovery/eval kits with a display, not sure what sizes
2019-01-07T02:51:29 < bitmask> mmm pickle flavored potato chips
2019-01-07T02:55:47 < englishman> hey munki
2019-01-07T02:56:10 < englishman> esp8266 plus external display memory? yikes
2019-01-07T02:57:02 < englishman> for that price, lunix + shitberreypi compute module for sure
2019-01-07T02:57:06 < tjq> I need to set the cuck frequency
2019-01-07T03:07:41 < englishman> wow you guys wasted no time in chasing off a noob

2019-01-07T04:09:35 < munki_> englishman: yeah i won't be using esp for sure
2019-01-07T04:09:46 < munki_> that's why i was wondering about other uC with larger ram available
2019-01-07T04:10:02 < dongs> why would you limit yourself not to use esp1477
2019-01-07T04:10:20 < munki_> only esp1488 here
2019-01-07T04:11:32 < dongs> munki, FTDI sells t his "EVE" shit
2019-01-07T04:11:38 < dongs> that will drive the screen size you need
2019-01-07T04:11:41 < dongs> and you just send it drawing commands
2019-01-07T04:11:47 < dongs> like 'draw line, draw circle, fill rect'
2019-01-07T04:11:58 < dongs> then you can use it even with esp1488 or retarduino
2019-01-07T04:12:02 < munki_> interesting
2019-01-07T04:12:22 < dongs> looks like they're on 3rd gen of that
2019-01-07T04:12:30 < dongs> https://www.ftdichip.com/Products/ICs/BT81X.html
2019-01-07T04:12:48 < munki_> i will say, the 4D library had some good features i liked specifically the ability to send an entire screen buffer over 4-byte SPI words
2019-01-07T04:12:55 < dongs> yes, this is similar to 4D shit
2019-01-07T04:13:18 < munki_> it's for the next version of htis https://github.com/thatfunkymunki/pumpbadge/blob/master/pumpbadge.ino
2019-01-07T04:13:21 < dongs> so if that stuff would have worked for you (but was too fucking expensive) then FTDI would be ok
2019-01-07T04:13:35 < munki_> which i used the gay little 4d display
2019-01-07T04:13:54 < munki_> but i want something better and more pixxxels so i can display actual ansi art and not just gay little blox of mirc art
2019-01-07T04:14:11 < dongs> FTDI it is
2019-01-07T04:14:18 < dongs> anything else is gonna involve way too much aids
2019-01-07T04:14:24 < munki_> figures
2019-01-07T04:14:24 < dongs> i mean youcould setupo a F4 with external sdram
2019-01-07T04:14:27 < dongs> and 24bit LCD 
2019-01-07T04:14:31 < dongs> but you'll spend a year routing it
2019-01-07T04:14:35 < dongs> and then another year writing firmware
2019-01-07T04:14:35 < munki_> lololo
2019-01-07T04:14:40 < dongs> ftdi, you buy their evalboard
2019-01-07T04:14:41 < munki_> yeah that's what i was hoping to avoid
2019-01-07T04:14:46 < dongs> hook it up to some -discovery with SPI
2019-01-07T04:14:48 < dongs> code your shit
2019-01-07T04:14:54 < dongs> then make a board and route in like 1 hour
2019-01-07T04:14:55 < dongs> done
2019-01-07T04:14:59 < munki_> true
2019-01-07T04:15:00 < munki_> good call
2019-01-07T04:16:09 < dongs> anyway i used it for some proj a while ago, the FT800 thing
2019-01-07T04:16:22 < dongs> it wasn't awful, and since they're on 3rd gen now its probly still selling and doing OK
2019-01-07T04:16:31 < dongs> and you can always buy that shit on digikey so thats a bonus
2019-01-07T04:16:40 < dongs> not some random china IC that may be EOL tomororw
2019-01-07T04:18:26 < munki_> thx for the tip
2019-01-07T04:18:41 < munki_> i'll buy their dev board and have a look
2019-01-07T04:23:19 < dongs> https://www.youtube.com/watch?v=qwQ3yGBknGA
2019-01-07T04:23:24 < dongs> you could totally scroll bigmatix here
2019-01-07T04:23:43 < munki_> already did :D https://www.youtube.com/watch?v=j13i0H_oam0
2019-01-07T04:23:54 < dongs> lols
2019-01-07T04:26:11 < munki_> it was p cool, read pumps directly from sd card
2019-01-07T04:26:49 < englishman> cool ftdi chip

2019-01-07T11:26:48 < dongs> CC
2019-01-07T11:26:55 < dongs> it dpeends on timer
2019-01-07T11:27:02 < dongs> some of them just use a generic TIMx_IRQ
2019-01-07T11:27:09 < dongs> and then you check flag and pull CC or update or wahtever
2019-01-07T11:27:09 < rajkosto> its on TIM1
2019-01-07T11:27:16 < rajkosto> which flag tho
2019-01-07T11:27:17 < dongs> ok, then TIM1 has a separate CC irq
2019-01-07T11:30:55 < rajkosto> does ARR, OPM matter for this use case ?
2019-01-07T11:32:21 < zyp> yes
2019-01-07T11:32:49 < zyp> you can use ARR to set a timeout
2019-01-07T11:33:16 < rajkosto> i think OPM should be on as its getting externally triggered
2019-01-07T11:33:25 < zyp> no
2019-01-07T11:33:53 < zyp> or maybe, idk, I don't think I used it
2019-01-07T11:34:06 < kakimir> dongs: ouch
2019-01-07T11:34:49 < kakimir> how is innovation?
2019-01-07T11:36:22 < zyp> rajkosto, here's some code I wrote many years ago, using that mode to decode shit: https://cgit.jvnv.net/suzumebachi/tree/drivers/ppmsum.cpp
2019-01-07T11:37:11 < zyp> hitting ARR triggers line 16, first edge of a pulse triggers line 21 and last edge of a pulse triggers line 32
2019-01-07T11:39:17 < zyp> each update sends a train of pulses, I store the width of each pulse, between each train there's at least 5000 clocks, so I use a long period to detect when a new train starts
2019-01-07T11:40:08 < zyp> if I stop getting updates at all, I'll run into ARR and call it a timeout
2019-01-07T11:40:33 < rajkosto> OPM should be off because the slave mode is set to Reset not Trigger
2019-01-07T11:40:40 < zyp> yes
2019-01-07T11:45:13 < zyp> just empty it out after each suck
2019-01-07T11:45:26 < rajkosto> push the button rapidly a few times
2019-01-07T11:45:28 < zyp> push the plunger all the way
2019-01-07T11:45:48 < zyp> on mine, that makes it protrude all the way through the tip
2019-01-07T11:46:19 < zyp> I recommend having a trashcan nearby for this purpose :p
2019-01-07T11:55:26 < zyp> no, it's common
2019-01-07T11:56:09 < zyp> adding more gets you better heat transfer
2019-01-07T11:56:10 < tjq> ah the pump
2019-01-07T11:57:25 < tjq> i still use one http://www.edsyn.com/product/DS017.html , it's quicker than waiting for my vacuum desolderer to heat up
2019-01-07T11:57:55 < tjq> do regularly clean the inside if your suction is weak and relube it with petroleum jelly (lol)
2019-01-07T12:02:28 < rajkosto> it wasnt cuz it came otu with plunger push
2019-01-07T12:02:45 < rajkosto> the actual clog is when you have to dissasemble it and clean the spring of tiny flecks
2019-01-07T12:03:11 < rajkosto> btw if the tip is filled with solder thats stuck to the tip you can use soldering iron to get it out
2019-01-07T12:03:16 < karlp> man, arm.com does the least possible worst implementation of "opt out of cookies" I've seen in a while.
2019-01-07T12:03:28 < tjq> i just jam the tip in upside down to clean it
2019-01-07T12:03:39 < karlp> "here's some things we're using, go visit each of their sites one by one in turn to learn how you can opt out"
2019-01-07T12:04:13 < tjq> karlp: my interpretation of 99% of the things is 'accept cookies or don't use our site at all'
2019-01-07T12:05:05 < karlp> yeah, "nice" ones have things that actually let you opt out, but msot of the rest do seem to be "fuck yall, your coice is to leave"
2019-01-07T12:05:42 < rajkosto> zyp, i see you also did TIM_UpdateRequestConfig(DIM_TIMER, TIM_UpdateSource_Global);
2019-01-07T12:05:49 < rajkosto> thats not in the RM0008
2019-01-07T12:06:38 < zyp> huh?
2019-01-07T12:06:53 < rajkosto> set 0x4 in CR1
2019-01-07T12:07:24 < zyp> let me look up the RM so I can give you an answer as to why
2019-01-07T12:07:40 < rajkosto> https://images.sshnuke.net/2019-01-07_11-07-39_q5lxfXh23.png
2019-01-07T12:08:01 < rajkosto> i guess to suppress update interrupt via slave controller ?
2019-01-07T12:08:41 < zyp> exactly, I don't want UIF set when the first edge triggers a reset, just when ARR causes overflow
2019-01-07T12:09:07 < zyp> it's only relevant if you use ARR as a timeout mechanism
2019-01-07T12:09:29 < rajkosto> TIM1 has separate CC and UPD interrupts
2019-01-07T12:09:41 < rajkosto> guess i gotta enable both and clear accordingly
2019-01-07T12:10:06 < zyp> you mean they are hooked to different IRQs?
2019-01-07T12:10:13 < rajkosto> yes
2019-01-07T12:10:28 < rajkosto> https://images.sshnuke.net/2019-01-07_11-10-27_cCcjN2TnT.png
2019-01-07T12:10:50 < zyp> doesn't make a big difference, if you point both at the same ISR, you can handle it the same way as the other timers with only one IRQ
2019-01-07T12:11:04 < zyp> or you can split the ISR into two
2019-01-07T12:12:34 < zyp> after all, you don't interact with the IRQ itself apart from enabling it in the NVIC, you just clear the flags in the timer and they are the same regardless of how which IRQs they are routed to
2019-01-07T12:12:50 < rajkosto> you can clear the interupt flag only or the full timer flag
2019-01-07T12:13:12 < rajkosto> (gotta clear at least one of them otherwise the interrupt will just repeat forever)
2019-01-07T12:13:33 < zyp> what do you mean by full timer flag?
2019-01-07T12:13:43 < rajkosto> TIM_SetFlagStatus is full timer flag
2019-01-07T12:13:49 < rajkosto> TIM_ClearITPendingBit is just interrupt flag
2019-01-07T12:14:02 < zyp> those function names doesn't tell me anything :)
2019-01-07T12:14:12 < rajkosto> google them they are in cmsis/stdperiph
2019-01-07T12:14:41 < zyp> I'm not really all that interested :p
2019-01-07T12:14:52 < rajkosto> of course you arent, you dont even label your bits as constants

2019-01-07T12:15:37 < karlp> no shit.

2019-01-07T12:16:17 < zyp> karlp, wanting other help is not unreasonable when the help you get is not useful :)
2019-01-07T12:19:05 < rajkosto> TIM_ClearITPendingBit and TIM_ClearFlag seem to actually do the same thing

2019-01-07T12:51:58 < rajkosto> the reading stuff works but overflow seems to trigger every cycle
2019-01-07T12:55:48 < rajkosto> kinda need the overflow tho, because when the input signal is 100%, its just a constant 1 level, so i need to set that there
2019-01-07T13:05:35 < rajkosto> the key to yours, zyp, is that you have one interrupt handler
2019-01-07T13:06:05 < rajkosto> doing this makes it work https://pastebin.com/Qk4jtjUg
2019-01-07T13:06:18 < zyp> ah, of course, I use if/else
2019-01-07T13:07:09 < zyp> well, like I said, you can just register the same ISR for both IRQs
2019-01-07T13:08:27 < rajkosto> its good like this
2019-01-07T13:21:03 < englishman> the same company that is installing public EV charging stations is also selling private recharging stations to companies, with the same logos and interface as the public ones

2019-01-07T14:32:31 < Ecco> and size of transctions on the AXI bus depend on MPU settings
2019-01-07T14:32:44 < Ecco> apparently they do NOT depend on the CPU instruction
2019-01-07T14:32:46 < Ecco> "The memory region MPU attribute must be configured as “Device” or “strongly-ordered” in order to prevent issues on devices that do not have the byte select feature. As an example, if byte accesses are performed to 16-bit memories with the MPU attribute set to “Normal memory”, the AXI transaction size is 64 bits and the FMC splits the transaction into four consecutive accesses while only one 
2019-01-07T14:32:52 < Ecco> access is expected instead of four."

2019-01-07T16:17:48 < zyp> I see utility in having multiple cores, since you can dedicate one to a high frequency task and not have to worry about latency and context switching overhead
2019-01-07T16:18:11 < zyp> but six cores might be going a bit too far :)

2019-01-07T16:19:32 < zyp> if you simply need six cores to get enough number crushing power, cm4f is probably not the right platform for the application

2019-01-07T16:45:26 < aandrew> USBD_LL_Transmit() calls HAL_PCD_EP_Transmit() calls USB_EPStartXfer(). that sees it's not ZLP, sets up USBx_INEP (ep->num is right, 0x01 for pipe 0x81), not using DMA.
2019-01-07T16:46:12 < aandrew> that sets USBx_DEVICE->DIEPEMPMSK to unmask the endpoint interupt and then boom, infinite interrupts

2019-01-07T16:46:26 < zyp> well, I presume third party code is supposed to work, so let's start looking at your code

2019-01-07T16:46:45 < aandrew> one moment, let me gather that in a pastebin
2019-01-07T16:46:59 < aandrew> could just be a matter of needing to use DMA
2019-01-07T16:47:29 < zyp> you don't need to use DMA to do USB on any of the cores
2019-01-07T16:47:58 < aandrew> no but perhaps the code is half-DMA enabled because of some stupid thing

2019-01-07T16:48:04 < zyp> only OTG_HS supports it at all, but you don't need to do it, you can treat it the same as OTG_FS and write data yourself instead
2019-01-07T16:48:08 < aandrew> I wonder if my FIFO setup is worng
2019-01-07T16:48:12 < zyp> yeah
2019-01-07T16:48:16 < zyp> I was about to say
2019-01-07T16:48:24 < aandrew> HAL_PCDEx_SetRxFiFo(&hpcd_USB_OTG_FS, 0x40);
2019-01-07T16:48:29 < aandrew> HAL_PCDEx_SetTxFiFo(&hpcd_USB_OTG_FS, 0, 0x80);
2019-01-07T16:48:32 < aandrew> that's all I'm doing
2019-01-07T16:48:44 < aandrew> but I don't know the correct way there
2019-01-07T16:48:51 < zyp> my loose guess is that you've forgot to configure the tx endpoint correctly, so you write garbage into the rxfifo area
2019-01-07T16:48:52 < aandrew> my only two endpoints are 0x81 and 0x02
2019-01-07T16:49:04 < zyp> that 0 is probably the offset in the fifo ram
2019-01-07T16:49:35 < zyp> with a 0x40-sized rxfifo, you'd want txfifo to start at offset 0x40
2019-01-07T16:50:06 < aandrew> that 0 is the tx fifo number
2019-01-07T16:50:10 < aandrew> (from reading the source
2019-01-07T16:50:15 < zyp> oh, okay
2019-01-07T16:50:35 < zyp> does the source keep an allocator so you always get a free area then?

2019-01-07T16:51:42 < aandrew> https://pastebin.com/aa5iafwy
2019-01-07T16:51:46 < aandrew> that is the HAL function
2019-01-07T16:52:27 < aandrew> basically it calculates the FIFO address by walking through the FIFO list and summing the sizes to figure out the fifo's start address
2019-01-07T16:52:56 < zyp> ah, right
2019-01-07T16:53:25 < aandrew> I'm not getting the mapping between fifo number and endpoint number though
2019-01-07T16:53:29 < zyp> but you're only configuring the txfifo for EP0, not for EP2
2019-01-07T16:53:50 < aandrew> is fifo # = ep# ?
2019-01-07T16:53:55 < zyp> yes
2019-01-07T16:53:57 < aandrew> aha
2019-01-07T16:54:08 < zyp> you need EP0 for control as well
2019-01-07T16:54:22 < aandrew> right
2019-01-07T16:54:37 < zyp> also, you don't need to do 0x81 and 0x02, you can do 0x81 and 0x01

2019-01-07T16:54:43 < zyp> in/out are independent
2019-01-07T16:55:07 < zyp> yeah, but the standard stuff still needs the txfifo
2019-01-07T16:55:12 < aandrew> hm, everything I've ever done on USB has said that endpoints *are* independent but ep & 0x7f must be unique
2019-01-07T16:55:27 < zyp> no, that is not true
2019-01-07T16:56:06 < zyp> only control endpoints have any relation between in and out, other endpoints are fully independent
2019-01-07T16:56:17 < zyp> and then it's up to hardware which ones are actually available
2019-01-07T16:56:32 < aandrew> hm ok
2019-01-07T16:56:56 < aandrew> success!
2019-01-07T16:57:13 < aandrew> HAL_PCDEx_SetRxFiFo(&hpcd_USB_OTG_FS, 0x40);
2019-01-07T16:57:13 < aandrew> HAL_PCDEx_SetTxFiFo(&hpcd_USB_OTG_FS, 0, 0x40);
2019-01-07T16:57:13 < aandrew> HAL_PCDEx_SetTxFiFo(&hpcd_USB_OTG_FS, 1, 0x80);
2019-01-07T16:57:13 < aandrew> HAL_PCDEx_SetTxFiFo(&hpcd_USB_OTG_FS, 2, 0x80);
2019-01-07T16:57:38 < aandrew> had to allocate '1' as well (guess the default/reset config is bad/invalid)
2019-01-07T16:57:45 < zyp> I think size is expressed in words
2019-01-07T16:57:46 < aandrew> gonna flip over to 0x81 and 0x01 as well now
2019-01-07T16:58:00 < aandrew> zyp: I think so too, but when I had the rxfifo set to 0x10 it did not work at all
2019-01-07T16:58:17 < aandrew> or raher it worked on osx/linux but not on windows ... would not enumerate and on osx/linux would enumerate after many seconds
2019-01-07T16:58:22 < zyp> well, rxfifo is shared and also stores metadata in addition to packet payloads
2019-01-07T16:58:49 < zyp> so 256 is a reasonable value for the rxfifo, I think that's what I default to in my stack as well
2019-01-07T16:59:02 < zyp> 0x40*4 = 256
2019-01-07T16:59:21 < zyp> but for the txfifos, you don't really need to do any more than 64 bytes each
2019-01-07T16:59:45 < zyp> unless you're doing high speed or isochronous or actually got dual buffering to work
2019-01-07T17:00:19 < zyp> i.e. 0x10 words each is plenty
2019-01-07T17:00:24 < aandrew> right, *eventually* this will be HS with external phy but not at the moment
2019-01-07T17:00:55 < zyp> OTG_HS has larger ram available for fifos
2019-01-07T17:01:06 < zyp> IIRC OTG_FS has 1.25k and OTG_HS has 4k
2019-01-07T17:01:37 < aandrew> 0x81/0x01 works too
2019-01-07T17:01:48 < aandrew> zyp: yep. gotta wlak before I run though :-)
2019-01-07T17:01:55 < aandrew> ok so it was just fifo bullshit screwing me
2019-01-07T17:02:05 < zyp> so with the code you pasted, last half of txfifo2 is actually overflowing
2019-01-07T17:02:09 < aandrew> thank you for the rubber duck debugging, zyp 
2019-01-07T17:02:22 < zyp> so that'll give you some fun issues once you've transferred a few packets :)
2019-01-07T17:02:27 < aandrew> zyp: right, and if I tranferred larger packets I'd see it
2019-01-07T17:02:34 < zyp> not larger, more
2019-01-07T17:02:37 < aandrew> I'll clean that up now, but the rxfifo size was confusing me
2019-01-07T17:02:52 < aandrew> oh, fifo, right
2019-01-07T17:02:56 < zyp> I believe in practice the fifos are ringbuffers
2019-01-07T17:03:58 < aandrew> what was that C++ code you pasted, si that your usb library stuff?
2019-01-07T17:04:06 < zyp> yes
2019-01-07T17:04:44 < zyp> I'm familiar with a bunch of usb issues because I've ran into them myself before :)
2019-01-07T17:04:44 < aandrew> nice
2019-01-07T17:05:10 < aandrew> naturally
2019-01-07T17:05:17 < aandrew> thank you for the help, very much appreciated
2019-01-07T17:05:20 < zyp> np
2019-01-07T17:06:18 < aandrew> hm, where did you read about the rxfifo RAM use? GRXFSIZ docu only says min 16 dwords, max 1024 dwords and must respect the amount of FIFO memory and not exceed the power-on value
2019-01-07T17:07:18 < zyp> the reference manual states somewhere that you need to keep enough space for at least MPS plus three back to back SETUP packets or something like that
2019-01-07T17:07:45 < zyp> and there's also metadata stored in there, when you read out GRXSTSP, it's actually popping the rxfifo

2019-01-07T17:10:39 < zyp> and this is the minimum
2019-01-07T17:11:22 < zyp> if you have larger OUT endpoints that EP0, (i.e. HS or iso), you need to have room for the largest OUT packet that you can receive
2019-01-07T17:12:01 < aandrew> ok, that's 37.16.6 in RM0385 (for STM32F75x)
2019-01-07T17:14:10 < aandrew> man USB is such a shit peripheral. insanely complicated for what it can actually do
2019-01-07T17:14:18 < aandrew> no wonder everyone prefers ethernet. :-)
2019-01-07T17:15:32 < zyp> haha
2019-01-07T17:15:47 < zyp> dwc_otg is super complex though
2019-01-07T17:16:26 < zyp> the device only periph in other stm32s have like five global registers and one per endpoint :)

2019-01-07T17:18:28 < karlp> dwc_otg, because you buy IP from "trusted" brands, regardless of actual quality...
2019-01-07T17:19:19 < zyp> ethernet in itself is fairly simple, but as soon as you layer TCP/IP on top of it, you've got more complexity than a small usb stack got :)
2019-01-07T17:20:14 < zyp> karlp, I wouldn't say it's that bad
2019-01-07T17:21:57 < zyp> I'd say dwc_otg is a better design than st_usbfs, the latter is a little bit too simple
2019-01-07T17:22:29 < karlp> was just taking a jab a snps
2019-01-07T17:22:47 < karlp> there's been a slew of fixes and hacks related to dwc usb over the years, 
2019-01-07T17:22:58 < zyp> I know
2019-01-07T17:23:09 < karlp> but no real evidence anyone elses IP cores are significantly better/worse.
2019-01-07T17:23:23 < karlp> inventra/musb is pretty known to be garbage as well.
2019-01-07T17:23:59 < karlp> allwinner uses musb for gadget/host, and something else for device mode, with a mux internally that you need to also switch,  because inventra device mode is fail or something
2019-01-07T17:24:08 < zyp> I haven't looked at that many usb cores yet, but the one in stellaris has so far been the worst I've seen
2019-01-07T17:24:22 < zyp> I mean TI lm4f
2019-01-07T17:24:43 < karlp> that's th eown with the weird byte/word addressing right?
2019-01-07T17:25:48 < zyp> it has packet registers, not 32-bit aligned, yes
2019-01-07T17:25:53 < zyp> but other issues as well
2019-01-07T17:26:50 < zyp> IIRC it didn't tell you whether you got a SETUP packet or a data packet on rx0, so you just had to keep track of what you were expecting (and disregard that the host can choose to abort a request and send a new SETUP packet at any time)
2019-01-07T17:27:02 < zyp> or something like that
2019-01-07T17:27:05 < aandrew> what is dwc?
2019-01-07T17:27:11 < zyp> designware
2019-01-07T17:27:26 < zyp> synopsys' line of IP cores
2019-01-07T17:27:42 < aandrew> zyp: and yes, layer TCP/Ip on top and it's as complex as any USB stack, but it's a) faster and b) much more standardized
2019-01-07T17:27:50 < zyp> both the ethernet core and the OTG core used in stm32 are licensed from synopsys
2019-01-07T17:28:21 < zyp> which means that you find the same cores in a ton of other devices as well

2019-01-07T17:29:03 < zyp> efm32 and whatever the broadcom thing on rpi is also uses dwc_otg

2019-01-08T00:02:42 < srk> The FIREWALL is an additional protection syst em offered by microcontrollers of the STM32 L0 and L4 series. It is used to protect some parts of code or data inside the Flash or the SRAM memories from any attack intended to dump the code or to get visibility of the associated sensitive data.

2019-01-08T00:28:17 < aandrew> hm, interesting
2019-01-08T00:28:41 < aandrew> zyp: I'm finding that that fifo sizing is more tricky than it appears
2019-01-08T00:29:00 < karlp> heh :)
2019-01-08T00:29:02 < aandrew> my bulk descriptor says that the packet size is 0x80 bytes
2019-01-08T00:29:08 < karlp> max packet size
2019-01-08T00:29:13 < karlp> not packet size
2019-01-08T00:29:51 < aandrew> right, max packet size is 0x80 bytes
2019-01-08T00:30:12 < aandrew> if I set the fio to 0x20 dwords 9which is 0x80 bytes) it doesn't transmit
2019-01-08T00:32:24 < aandrew> if I set it to 0x40, it hangs like it did when my fifos were misconfigured
2019-01-08T00:32:57 < aandrew> if I set it to 0x80 it doesn't hang anymore, but the PC doesn't get any data back either (libusb_bulk_xfer returns 0, and len read is 0)
2019-01-08T00:33:11 < aandrew> if I do it enough it changes from no error to stalled endpoint after 32 reads
2019-01-08T00:33:35 < aandrew> but 0x80 dwords plus 0x40 dwords plus 0x40 dwords is more than the 1.5k I think
2019-01-08T00:33:55 < aandrew> 256+256+512, no tha'ts 1k

2019-01-08T18:27:53 < aandrew> yeah dont' do that
2019-01-08T18:28:13 < aandrew> I bought like a hundred of the displays (not the board too); they're handy little indicators and dirt cheap, I think $0.93/ea
2019-01-08T18:28:22 < rajkosto> the bottom of the glass is slightly floating 
2019-01-08T18:28:27 < aandrew> yep it is
2019-01-08T18:28:29 < rajkosto> the part where the display is, is solidly glued on
2019-01-08T18:28:41 < rajkosto> i was pushing it into a connector on all 4 corners and the bottom left cracked
2019-01-08T18:28:46 < aandrew> and the glas is unused, but I bet the crack caused problems that severed traces on the glass that wasn't cracked
2019-01-08T18:28:56 < rajkosto> theres like a billion traces there, microscopic
2019-01-08T18:29:14 < rajkosto> the trace "ribbon" is on the cracked line
2019-01-08T18:29:15 < aandrew> depends on where exactly it cracked but yes

2019-01-08T21:31:56 < rajkosto> ok so my SPI NSS isnt changing
2019-01-08T21:32:23 < rajkosto> why is everyone just using it as a GPIO in the examples
2019-01-08T21:32:44 < jpa-> because the hardware management often isn't what you actually want
2019-01-08T21:33:02 < rajkosto> shouldnt CR1 |= 0100 etc toggle it manually
2019-01-08T21:33:19 < rajkosto> when its configured with 0x200
2019-01-08T21:33:22 < rajkosto> (SPI_NSS_Soft)
2019-01-08T21:34:11 < jpa-> i think that only matters when you are using it as SPI slave
2019-01-08T21:44:11 < rajkosto> well when i use GPIO to toggle CS i get this weird situation

2019-01-08T22:37:17 < Thorn> from my lpc startup file: /* blank the bss section */ while (dest < &_ebss) *(dest++) = 0;

2019-01-08T22:37:52 < Thorn> (looks like they assume bss goes after data, so they don't even initialize dest at the start of the loop)

2019-01-08T23:16:03 < catphish> does it matter?
2019-01-08T23:16:12 < malinus> meh I let the hardware guys keep track of who owns who in each particular month ;)
2019-01-08T23:16:20 < catphish> as long as it gets done, and the memory init doesn't depend on it, it's all good
2019-01-08T23:16:34 < MrMobius> my favorite startup bug is when it takes too long to initialize .data and the watchdog timer resets it before it gets to your first line turning it off
2019-01-08T23:16:58 < catphish> lol
2019-01-08T23:17:04 < malinus> MrMobius: fucking TI never clear the BSS and use that as an excuse
2019-01-08T23:17:23 < malinus> even though it should be done according to the C standards iirc
2019-01-08T23:18:36 < catphish> c says it should be done, doesn't say who should do it, or when :)
2019-01-08T23:19:42 < malinus> allright. Either way it won't get done with whatever standard toolchain+startup code TI provides ;)
2019-01-08T23:19:55 < catphish> well that sucks

2019-01-08T23:45:02 < invzim> like, on irc, here
2019-01-08T23:45:26 < Thorn> I have, for displays
2019-01-08T23:45:28 < invzim> is it correct that there are 2 versions, depending on if you want the leads to be on top or bottom?
2019-01-08T23:45:49 < Thorn> yes top/bottom contact
2019-01-08T23:45:57 < invzim> ordered 5 of these to sample, https://www.buydisplay.com/default/128x64-oled-i2c-0-96-display-white-color-connector-fpc-ssd1306
2019-01-08T23:46:44 < invzim> guess you have to watch your step when making the parts in regards to pin numbering :)
2019-01-08T23:47:16 <@Steffanx> why
2019-01-08T23:48:01 < Thorn> I used ERC12864-something and their pin numbering is the inverse of the numbering in the connector datasheet

2019-01-09T08:37:28 < dongs> it can
2019-01-09T08:37:30 < rajkosto> there dont seem to be any full color OLED
2019-01-09T08:37:32 < dongs> in china, anything is possible
2019-01-09T08:37:37 < dongs> suer there is plenty?
2019-01-09T08:37:44 < dongs> is 65k color full color enough for you?
2019-01-09T08:37:50 < rajkosto> https://www.aliexpress.com/item/IPS-0-96-inch-7P-SPI-HD-65K-Full-Color-LCD-Module-ST7735-Drive-IC-80/32859445140.html i want this but in OLED
2019-01-09T08:38:03 < rajkosto> i see RGB 96x64 OLED without a pcb for MUCH more
2019-01-09T08:38:13 < dongs> that fakeass image
2019-01-09T08:38:27 < rajkosto> do you like how its a honest seller so they put (Not OLED) in the description
2019-01-09T08:38:32 < rajkosto> but they still want the clicks from searching OLED ?
2019-01-09T08:39:09 < rajkosto> the other listings just cram TFT IPS OLED SPI I2C FULL COLOR LCD 
2019-01-09T08:39:20 < rajkosto> also the pins are labeled SCL and SDA even though its SPI
2019-01-09T08:39:26 < dongs> thats normal
2019-01-09T08:39:34 < dongs> most of those STwahtever controllers can do both
2019-01-09T08:39:39 < rajkosto> nah, the other blue pcbs have MISO
2019-01-09T08:39:46 < dongs> and if its SPI or i2c depends by some other strap pins
2019-01-09T08:39:55 < rajkosto> yes but this has no unpopulated resistors for that.
2019-01-09T08:40:04 < rajkosto> its only "4-SPI" as its says on the back
2019-01-09T08:40:53 < rajkosto> wonder why they dont make 8-bit OLED instead of 1-bit OLED, all it would take is more RAM in the controller since they already support PWM

2019-01-09T13:03:33 < jpa-> PeterM: it usually just means that the actual datasheet is in a different pdf
2019-01-09T13:05:14 < PeterM> in a lot of cases it can also mean we dont provide that data
2019-01-09T13:05:40 < qyx> don't be overly pessimistic
2019-01-09T13:06:22 < PeterM> most good manufacturers put the data in a seperate document for "characteristic data", but some dont provide it, its a pain in the ass
2019-01-09T13:07:55 < jpa-> well, with such unreliable manufacturers you are actually lucky if they don't just put out a fake datasheet

2019-01-09T13:08:11 < qyx> I am curious if it is enough to use the internatl STM32 ADC to interface to a strain gauge
2019-01-09T13:08:15 < qyx> with oversampling of course
2019-01-09T13:08:35 < qyx> or if it is better to use a dedicated adc
2019-01-09T13:09:01 < qyx> I would say stm32 is going to be more power hungy in this case
2019-01-09T13:09:27 < jpa-> it does what it's specced to do, for many strain gauge applications even non-oversampled ~10bit effective resolution could be enough
2019-01-09T13:09:46 < PeterM> nah even big manufactuerers do it, but its mostly on trash teir parts
2019-01-09T13:11:29 < karlp> PeterM: similar I guess.  I have had those joys with capacitor datasheets too :)

2019-01-09T20:23:55 < dongs> only captures like ~200 transitions
2019-01-09T20:24:00 < dongs> regardless of your depth
2019-01-09T20:24:12 < dongs> i think mso channels rob proportional number of bits from 20mbit samples
2019-01-09T20:24:20 < dongs> so if you have x channels on, its gonna be 20/x leftover
2019-01-09T20:24:42 < dongs> and then magnishit just samples like 100-200 or someshit per channel, like it does in fastview scope mode
2019-01-09T20:27:09 < dongs> huh
2019-01-09T20:27:16 < dongs> it cant even save waveforms from digital part.

2019-01-09T23:07:02 < aandrew> but then the very next thing windows does is issue a vendor request with bRequest equal to whateer number you gave them in the OS String descriptor and index 4
2019-01-09T23:07:16 < aandrew> and that's all handled by USBD_StdDevReq()
2019-01-09T23:07:29 < aandrew> there's no hook in there to handle other device requests

2019-01-09T23:11:34 < aandrew> yep this looks like something overlooked by the cubemx usbd library code
2019-01-09T23:11:47 < aandrew> there's no way to catch device/interface requests that are not standard
2019-01-09T23:15:36 < karlp> locm3 can let you do that, butt it doesn't (yet) support the non-sequential stringiids that that MS stuff needs.
2019-01-09T23:15:40 < karlp> software sucks :)
2019-01-09T23:16:32 < aandrew> yeah, I wouldn't mind if it didn't have ANY support for it
2019-01-09T23:16:38 < aandrew> but half-assed support is rage-inducing
2019-01-09T23:16:46 < aandrew> clearly nobody ever tried to do anything with it
2019-01-09T23:17:06 < karlp> I'd say you're just expected to hack in all the files, layering be damned
2019-01-09T23:17:32 < karlp> that's what I found most confusing with the cubemx code, which bits you were _meant_ to touch, and which bits you shouldn't have to, but probably would anyay
2019-01-09T23:17:53 < karlp> at least you have usb, mbed still doesn't

2019-01-09T23:47:48 < aandrew> zyp: usb here is only a stepping stone, I am ultimately using ethernet
2019-01-09T23:47:53 < aandrew> why they want to test with usb is beyond me
2019-01-09T23:47:59 < catphish> zyp: ah yes
2019-01-09T23:48:03 < aandrew> probably becuase they feel they can't write a simple ethernet switch in HDL too fast
2019-01-09T23:48:19 < zyp> heh :)
2019-01-09T23:48:21 < aandrew> englishman: so car-san I thinkw ill be out of business within 6mos. sad but true
2019-01-09T23:48:38 < aandrew> englishman: their main machine programmer did not come back from their christmas shutdown
2019-01-09T23:48:45 < catphish> there's a guy around these parts making an fpga ethernet switch
2019-01-09T23:48:46 < englishman> rip
2019-01-09T23:48:46 < aandrew> so the machines could not be programmed
2019-01-09T23:48:55 < zyp> what are you gonna do for testing then? usb ethernet?
2019-01-09T23:49:01 < aandrew> they called in one of the daughters who has experience with it
2019-01-09T23:49:02 < englishman> no documentation = rip
2019-01-09T23:49:07 < englishman> relying on a single employee = rip
2019-01-09T23:49:22 < aandrew> the daughters were scheduled to runt he entire company since the old man retired but there was some serious shit went down and both daughters left to find other jobs
2019-01-09T23:49:34 < aandrew> englishman: yep
2019-01-09T23:49:35 < englishman> continue
2019-01-09T23:49:59 < zyp> usb ethernet in the simplest variants are fairly easy; just write the right descriptors and set up a pair of bulk pipes, one for each direction
2019-01-09T23:50:00 < englishman> surface scratching has revealed fail underneath a very thin coat of marketing
2019-01-09T23:50:07 < aandrew> anyway the less angry of the two daughters came back and they've got the machine programmed and unless other excrement hit the air conditioning, the bottom of the panel was done today
2019-01-09T23:50:12 < aandrew> top tomorrow
2019-01-09T23:50:23 < aandrew> zyp: nah, I just did a simple bulk device
2019-01-09T23:50:45 < zyp> then you just send ethernet packets as bulk transfers on one pipe and receive ethernet packets on the other
2019-01-09T23:51:01 < aandrew> but what's upset me is that they didn't tell me they were struggling so I could work with it
2019-01-09T23:51:10 < zyp> aandrew, plain bulk that you're sending ethernet packets over?
2019-01-09T23:51:16 < aandrew> and I'm currently in turks and caicos supposedly on a vacation
2019-01-09T23:51:23 < aandrew> zyp: no, not sending ethernet at all
2019-01-09T23:51:26 < aandrew> just bulk 
2019-01-09T23:51:27 < zyp> ah, ok
2019-01-09T23:51:48 < aandrew> they send me a control struct, I use that to set up the payload return whcih is just a series of another struct filled with dummy data
2019-01-09T23:52:00 < aandrew> englishman: nah they don't do marketing
2019-01-09T23:52:19 < aandrew> the old man started the company 30y ago and it's been steadily declining in the last 2-3 years
2019-01-09T23:53:02 < aandrew> I tried to help them by trying to rejig them as a maker/proto house where if people put shit in a standard format it would take less manpower to setup/mfg but they didn't want ot do it
2019-01-09T23:53:07 < aandrew> basically like a macrofab or something
2019-01-09T23:53:12 < aandrew> so whatever
2019-01-09T23:53:16 < englishman> theres no money in that really
2019-01-09T23:53:20 < englishman> idk how macrofab does it
2019-01-09T23:53:29 < englishman> probably burning thru cash
2019-01-09T23:53:35 < aandrew> there's no money in what they're doing now but at least with the college and two universities they might have some steady work
2019-01-09T23:53:38 < zyp> I couldn't sleep last night so I ended up lying awake at 4AM thinking about how some simple IP/UDP implementation and an ER-X for the test setup would be really convenient
2019-01-09T23:53:46 < aandrew> ER-X?
2019-01-09T23:53:47 < zyp> for workstuff
2019-01-09T23:53:51 < zyp> edgerouter x
2019-01-09T23:54:35 < aandrew> anyway that's my story. it's sad because I"ve known them for 20y but really it's one of those if you don't want to help yourself I can't help either kind of situations
2019-01-09T23:54:46 < aandrew> shoudl have given it off to OES in london or something
2019-01-09T23:54:57 < zyp> I have a bunch of stuff that runs some L2 protocol where one node will be a master and the rest are slaves
2019-01-09T23:55:26 < aandrew> nice
2019-01-09T23:55:35 < zyp> and then for testing people would like to run multiple masters, and that doesn't work with the protocol, so I hacked up some other stuff before that uses raw ethernet frames and MAC addressing
2019-01-09T23:55:39 < aandrew> I've thought of SDN with an FPGA but it's nothing real vendors haven't already thought of
2019-01-09T23:55:42 < aandrew> just an interesting idea
2019-01-09T23:55:43 < zyp> and it's a hassle to maintain
2019-01-09T23:55:56 < zyp> and raw ethernet is annoying to deal with on windows
2019-01-09T23:56:46 < zyp> winpcap makes it possible, but it's kinda fragile and doesn't deal well with a lot of uninteresting traffic since I have to accept everything and filter in software
2019-01-09T23:57:07 < aandrew> that sounds like a royal pita
2019-01-09T23:57:11 < zyp> yeah
2019-01-09T23:57:49 < zyp> I was pondering last night on putting each master on its own VLAN, but windows doesn't really handle VLAN trunks either
2019-01-09T23:58:34 < zyp> and then I realized I could just make a thin IP/UDP layer that runs alongside the L2 protocol
2019-01-09T23:59:18 < zyp> ER-X is cheap and has five ports, so I could just put each master on its own L2 segment, ER-X would route the IP traffic and ignore the rest
2019-01-09T23:59:46 < zyp> and the interface software only has to deal with UDP which makes it a lot more sane to work with on windows

2019-01-10T00:01:44 < catphish> yep

2019-01-10T00:03:44 < catphish> as far as router's go, it's probably the best value out there
2019-01-10T00:04:39 < aandrew> how good is edgeos?
2019-01-10T00:05:12 < zyp> any plain IP router has a number of interfaces each connected to a network segment
2019-01-10T00:06:00 < zyp> when IP traffic arrives on an interface, it'll be routed to wherever it needs to go
2019-01-10T00:06:20 < zyp> other traffic that's not IP will simply be dropped as the router doesn't know what to do about it
2019-01-10T00:06:56 < catphish> aandrew: i really like it, very similar to junos
2019-01-10T00:07:25 < zyp> IIRC edgeos branced off from vyatta/vyos

2019-01-10T01:12:23 < zyp> a sled would be the trailer you hang after the snowmobile :p
2019-01-10T01:12:51 < kakimir> it would be a sleigh
2019-01-10T01:13:22 < zyp> aren't sled and sleigh the same word?
2019-01-10T01:15:05 < kakimir> anyway
2019-01-10T01:15:08 < kakimir> that is easy riding
2019-01-10T01:15:38 < kakimir> 1/3 throttle 1/2 throttle
2019-01-10T01:16:08 < kakimir> when conditions are right you can push those turns in full throttle with a much greater speed
2019-01-10T01:18:55 < kakimir> usually what happens is that I get exhausted and cannot keep it in the turn by countersteer + weight on another side and when it falls from the turn it throws the driver off
2019-01-10T01:20:03 < kakimir> kinda pointless to do that stuff at full power with 400kg sled
2019-01-10T01:20:38 < catphish> sounds fun
2019-01-10T01:21:02 < kakimir> just getting winded when you need to walk/run after the sled multiple times
2019-01-10T01:21:52 < catphish> drive better? :)
2019-01-10T01:22:57 < kakimir> ye
2019-01-10T01:25:31 < kakimir> steering has 5degrees free play and all the steering linkages are stiff as hell especially under stress

2019-01-10T01:27:29 < englishman> is that you tipping it over or you flying the drone
2019-01-10T01:27:42 < kakimir> tipping over
2019-01-10T01:27:53 < catphish> looks fun

2019-01-10T01:28:02 < catphish> best fix the steering
2019-01-10T01:28:08 < kakimir> actually not
2019-01-10T01:28:16 < kakimir> I wanted to do it first
2019-01-10T01:28:32 < kakimir> but the steering has like 20 moving parts and linkages
2019-01-10T01:28:41 < catphish> ah
2019-01-10T01:28:53 < kakimir> plastic bearings that wear out immidietelly
2019-01-10T01:29:14 < kakimir> there is no purpose to make it better than it needs to be
2019-01-10T01:29:31 < englishman> what kind of sled
2019-01-10T01:29:39 < kakimir> rs viking
2019-01-10T01:29:54 < englishman> kool
2019-01-10T01:31:28 < kakimir> when I tipped over the drone did automatic stop without controller input
2019-01-10T01:31:47 < kakimir> the collision avoidance is pretty good
2019-01-10T01:32:35 < kakimir> actually it stopped because I did stop
2019-01-10T01:34:37 < kakimir> issue with the system is chase shoots like chase car drifting on ice track

2019-01-10T01:35:28 < kakimir> when threshold for distance per current flight speed is reached it does full power stop and the car drives away
2019-01-10T01:37:31 < kakimir> so from it's flight controller perspective it thinks it's "10 meters from collision with static object"
2019-01-10T01:38:06 < kakimir> but the object (car) is actually moving almost identical speed with the drone

2019-01-10T02:21:41 < catphish> considering how many PIDs a drone has to run, you wouldn't think using one for anticollision would be a big challenge
2019-01-10T02:22:47 < catphish> but for most situations "stop when something is too close" is probably good enough

2019-01-10T13:11:29 < PeterM> its a bit of a situation of the more you look the worse it is
2019-01-10T13:12:18 < PeterM> upon first inspection it was just a case of no respect paid to clearance and creepage distances
2019-01-10T13:13:24 < Steffanx> Why its a trap PeterM?
2019-01-10T13:13:29 < PeterM> but looking closer it is a fundamentally terrible design and a endless list of terrible decisions, like 0402 resistors accross 250v 
2019-01-10T13:13:36 < Steffanx> Because you cant beat the dutchies
2019-01-10T13:13:43 < Steffanx> Or jappies?
2019-01-10T13:14:02 < Steffanx> Ah.
2019-01-10T13:14:45 < PeterM> there is no isolation between control electronics and drivetrain electronics, not even fucntional isolation
2019-01-10T13:15:36 < PeterM> the entire vehicle is carbon fiber and aluminium, so there is potential for say, an insulation breakdown in the motor to cause the chassis to become live
2019-01-10T13:16:19 < PeterM> and then the shared ground refrence in the control electronics with sweaty  hands putting 250v+ accross a person
2019-01-10T13:19:00 < PeterM> but im not touching that shit, im staying miles away

2019-01-10T13:29:22 < Steffanx> Isnt there a serious check on those cars before they can enter the competition PeterM
2019-01-10T13:30:07 < Steffanx> Or isnt it the "real" solar challenge
2019-01-10T13:36:02 < PeterM> no, the only serious checks are for cheating, not safety
2019-01-10T13:36:15 < PeterM> and it is the "real" solar challenge
2019-01-10T13:41:49 < specing> solar cars are an idiotic concept
2019-01-10T13:41:53 < specing> solar trikes though!
2019-01-10T13:42:15 < specing> solar recumbent tricycles, that is
2019-01-10T13:43:13 < PeterM> nah its all rpetty dumb
2019-01-10T13:43:33 < PeterM> the surface area required to generate enough electrical energy to provide propultion isnt practical
2019-01-10T13:43:51 < PeterM> its just a bit of a pissing contest
2019-01-10T13:43:52 < specing> well yes, batteries are going to weight less than panels unless you are going for 200km range
2019-01-10T13:44:19 < specing> PeterM: for a tricycle 200W would be enough for comfortable 50km/h with human assistance
2019-01-10T13:44:27 < englishman> thats what batteries are for

2019-01-10T13:48:38 < Haohmaru> now put a lamp and u got free energy!
2019-01-10T13:51:27 < specing> Lol

2019-01-10T14:07:04 < PeterM> specing yeah, as i said, laarge
2019-01-10T14:15:35 < specing> PeterM: it would still take up much less space than a car, so a net win for society
2019-01-10T14:16:08 < specing> not that we aren't already hopelessly fucked due to pollution
2019-01-10T14:17:24 < karlp> I'm with peter, solar for direct propulsion is dumb.
2019-01-10T14:19:42 < specing> it is not dumb, our expectations of speed are dumb
2019-01-10T14:19:53 < specing> speed and performance
2019-01-10T14:20:02 < englishman> solar is dumb especially where karlp and i live
2019-01-10T14:20:17 < englishman> autonomous vehicles powered by geothermal or hydroelectric is where it's at
2019-01-10T14:20:23 < englishman> so i can get to work at 300km/h
2019-01-10T14:20:43 < englishman> i can't wait until it is illegal to drive.
2019-01-10T14:21:06 < specing> now 300km/h is insane unless in a near-vacuum tube
2019-01-10T14:21:27 < englishman> or a series of autonomous vehicles all slipstreaming behind each other.
2019-01-10T14:21:28 < specing> englishman: why not skip this madness and work from home?
2019-01-10T14:21:45 < englishman> because i don't do software or customer support
2019-01-10T14:21:51 < specing> What do you do?
2019-01-10T14:21:53 < karlp> yeah, batteries for the vehicle, and solar for charging is totally sane.
2019-01-10T14:21:58 < englishman> drink coffee and chat
2019-01-10T14:22:08 < karlp> but putting solar on personal transportation devices is dumb
2019-01-10T14:22:15 < specing> englishman: you can drink coffee and chat with your neighbours, too
2019-01-10T14:22:23 < englishman> i'd also need a car to get to them
2019-01-10T14:22:56 < specing> karlp: solar on ocean lines would not be dumb
2019-01-10T14:23:12 < englishman> sails on ocean lines would make far more sense
2019-01-10T14:23:25 < specing> englishman: you can have a coffee and chat with your local bear population, then
2019-01-10T14:23:28 < englishman> even if they just run a generator
2019-01-10T14:23:47 < specing> englishman: why not both sails and solar?
2019-01-10T14:24:30 < englishman> maybe in a few years when panel production drops another order of magnitude and efficiency increases
2019-01-10T14:24:37 < englishman> *production cost
2019-01-10T14:25:02 < specing> panels already make cost in a few years, no?
2019-01-10T14:25:37 < qyx> they are ~100€ for nerly 300Wpk now
2019-01-10T14:25:46 < qyx> they were like double few years ago
2019-01-10T14:27:35 < specing> 100eur gets you 600kWh here, that is about a year of 300Wpk operation?

2019-01-10T14:37:14 < kakimir> how visible led is with 3mA?
2019-01-10T14:37:46 < kakimir> have you used led with such low current?
2019-01-10T14:38:29 < kakimir> leds are used only for debugging / troubleshooting
2019-01-10T14:40:26 < karlp> specing: I agree (re boats) that's why I said personal transportation
2019-01-10T14:41:00 < karlp> 3mA is heaps for leds.
2019-01-10T14:42:48 < specing> karlp: I'd say it would be visible but not annoying, 1kOhm resistor to led is standard at 3-5V, no?
2019-01-10T14:42:52 < specing> kakimir: ^
2019-01-10T14:43:21 < specing> For flashlight use it is 3-5A per LED
2019-01-10T14:47:54 < qyx> specing: one year is more like <400kWh
2019-01-10T14:48:17 < qyx> not counting other inefficiencies

2019-01-10T14:52:37 < qyx> if you are selling the electricity, maybe yes
2019-01-10T14:52:45 < qyx> you have to count all the infrastructure costs too
2019-01-10T14:52:55 < qyx> or batteries in a offgrid system
2019-01-10T14:53:06 < zyp> selling the electricity generally pays you less per kWh than you have to buy it for
2019-01-10T14:53:16 < qyx> here no
2019-01-10T14:53:49 < kakimir> I have 1k and 5v
2019-01-10T14:53:51 < kakimir> yellow leds
2019-01-10T14:54:01 < kakimir> every function on tester board has it's own led
2019-01-10T14:54:15 < qyx> at least when there were subsidies for it
2019-01-10T14:54:28 < qyx> you could sell for 0.38€/kWh iirc
2019-01-10T14:54:35 < qyx> and buy back for like 0.11 or so
2019-01-10T14:54:47 < kakimir> specing: bad flashlights drive maximum amperes
2019-01-10T14:54:56 < kakimir> or more
2019-01-10T14:55:01 < kakimir> efficiency is bad
2019-01-10T14:55:49 < kakimir> but in flash lights it's all shit anyways.. aluminum reflector, glass, bezel everything
2019-01-10T14:56:11 < kakimir> ending up with optical efficiency under 90%
2019-01-10T14:56:24 < specing> kakimir: it is either that or complicated optics and diode spam
2019-01-10T14:56:57 < kakimir> flashlights have lightweight optics though - and cheap
2019-01-10T14:57:07 < specing> Sure efficiency is about 40% lower than if the leds would be driven at 1/10 power, but it is more compact and much cheaper
2019-01-10T14:57:26 < kakimir> and there needs to be spot on flashlight light
2019-01-10T14:57:36 < kakimir> so you cannot just go crazy with optics
2019-01-10T14:58:11 < specing> what do you mean by 'spot on flashlight light'?
2019-01-10T14:58:24 < kakimir> flashlights are assumed to be throwers
2019-01-10T14:58:34 < specing> and yes you absolutely can go crazy with optics (see fenix BC21R for bicycle use)
2019-01-10T14:58:38 < specing> by whom?
2019-01-10T14:58:38 < kakimir> not close distance lights with a wide beam
2019-01-10T14:58:55 < specing> I have two headlamps with a TIR lens optimised for maximum flood
2019-01-10T14:59:42 < kakimir> bc21r is not a flashlight
2019-01-10T15:00:08 < specing> What is it, then?
2019-01-10T15:01:29 < kakimir> bicycle light
2019-01-10T15:03:12 < specing> that is just one subtype of flashlight
2019-01-10T15:04:20 < kakimir> maybe
2019-01-10T15:06:09 < kakimir> it's a blurred line
2019-01-10T15:08:10 < specing> its not blurred

2019-01-10T15:15:58 < joyce72> Hello, I am using CubeMX and System Workbench for STM32 to create a project. I am using the FATFS middleware in my project. When I try to build the project however, System Workbench complains that it cannot find a file ff_gen_drv.h
2019-01-10T15:16:10 < zyp> sorry to hear that
2019-01-10T15:16:32 < joyce72> I have checked the include paths, and the folder containing the sources for the FATFS middleware are indeed defined in the project
2019-01-10T15:16:41 < joyce72> Anyone dealt with this before?
2019-01-10T15:24:06 < jpa-> joyce72: well, does that file exist there?
2019-01-10T15:24:16 < joyce72> Yup
2019-01-10T15:24:29 < jpa-> ok, so it is basically a problem in using system workbench
2019-01-10T15:24:41 < joyce72> Right now, I have redone the sources

2019-01-10T22:05:05 < qyx> (there are eco reasons for wooden enclosure)
2019-01-10T22:05:30 < qyx> I am curious if the humidity reading will be ~~accurate

2019-01-10T22:07:24 < Ultrasauce> use a magnet+hall sensor to measure an internal dimension and use the box as the hygrometer

2019-01-11T00:50:06 < grindhold> which is the smallest (read: cheapest) stm32f1xx that supports usb host?
2019-01-11T00:51:12 < specing> does it need to be f1?
2019-01-11T00:51:47 < englishman> not sure, haven't applied a load yet

2019-01-11T00:52:24 < zyp> grindhold, I think f105/f107 are both host capable, but I'd rather go for f405
2019-01-11T00:52:35 < englishman> f04x should have usbotg host?

2019-01-11T00:53:23 < zyp> maybe get a f4-discovery, it comes with a f407 and all the OTG hardware
2019-01-11T00:53:31 < zyp> f407 is essentially a bigger f405
2019-01-11T00:53:46 < englishman> yes f4 thanks
2019-01-11T00:53:54 < grindhold> okay, so i should be able to develop in f407, port to f405 easily and use that in production?

2019-01-11T01:03:58 < zyp> IIRC the only difference between f405 and f407 is that f407 has ethernet
2019-01-11T01:04:49 < zyp> apart from that they're identical, so any code not using ethernet will run the same on both
2019-01-11T01:07:54 < aandrew> zyp: do you know any real difference between F767 and F756 regarding usb fs?
2019-01-11T01:10:44 < zyp> I haven't used f7 myself yet
2019-01-11T01:10:54 < zyp> let's see
2019-01-11T01:11:51 < zyp> according to the feature matrix on the homepage, I can't see any differences related to usb at all
2019-01-11T01:12:48 < zyp> only usb-related difference is that f7x3 apparently has a builtin HS PHY
2019-01-11T01:13:14 < zyp> apart from that it seems all parts in the f7 range has OTG_FS and OTG_HS just like f4
2019-01-11T01:13:30 < zyp> so I figure any difference would just be the number of supported endpoints on each, if any
2019-01-11T01:14:11 < zyp> f4 has 3/5 respectively, IIRC I read somewhere that some newer parts got 4/6 or something
2019-01-11T01:14:22 < zyp> but I don't remember which
2019-01-11T01:14:58 < zyp> btw, why are you asking?

2019-01-11T09:15:34 < dongs> im failing to 3-wire SPI
2019-01-11T09:18:11 < Haohmaru> how so
2019-01-11T09:18:16 < dongs> it doesnt work
2019-01-11T09:18:25 < Haohmaru> you didn't forget to chipselect, did you?
2019-01-11T09:18:45 < dongs> it works in 4 wire mode. im trying to get rid of 4th wire (SDO) because it injects current into stm in stadby
2019-01-11T09:19:03 < Haohmaru> SDO == MOSI?
2019-01-11T09:19:15 < dongs> miso
2019-01-11T09:19:19 < dongs> master in slave out
2019-01-11T09:19:25 < dongs> SDO from slave to STM32.
2019-01-11T09:19:55 < Haohmaru> put a 10k series resistor on it? ;P~
2019-01-11T09:19:58 < qyx> do you need bidirectional 3 wire?
2019-01-11T09:20:15 < qyx> or how are you failing removing one wire?
2019-01-11T09:20:20 < dongs> not really. im trying to hack aroudn it right now
2019-01-11T09:20:41 < qyx> wut, then simply disconnect it, no?
2019-01-11T09:21:03 < dongs> you need to put SPI peripheral into 3 wire mode too
2019-01-11T09:21:09 < Haohmaru> and make sure the disconnected input ain't floating
2019-01-11T09:21:13 < dongs> and it seems to have an effect on RXNE shit etc
2019-01-11T09:21:15 < qyx> no you dont
2019-01-11T09:21:17 < dongs> yes you do
2019-01-11T09:21:40 < qyx> and why are you messing with rxne if you don't want to receive?

2019-01-11T09:22:14 < Haohmaru> can't you set it up like it's 4-wire and just ignore the input data?
2019-01-11T09:22:35 < qyx> I did it and it worked
2019-01-11T09:22:41 < Haohmaru> or u need teh pin for something else?
2019-01-11T09:22:53 < dongs> qyx, the rxne shit is during spiTransfer()
2019-01-11T09:23:15 < dongs> just switching chip to 3wiore mode isnt working.
2019-01-11T09:23:15 < dongs> hmm
2019-01-11T09:24:24 < qyx> and what about using spi_send instead
2019-01-11T09:24:37 < qyx> also I still think it should work
2019-01-11T09:24:51 < qyx> because the spi peripheral dones't know the pin is disconnected
2019-01-11T09:24:58 < qyx> or configured to analol in or what
2019-01-11T09:25:04 < qyx> it will simply read all 0 or all 1
2019-01-11T09:25:24 < qyx> how are you setting 3wire? using BIDIMODE?
2019-01-11T09:25:43 < dongs> yeah
2019-01-11T09:25:48 < dongs> tho stdperiph calls it retardely somethign else
2019-01-11T09:26:37 < qyx> iirc it simply combines mosi and miso into one pin, I don't remember which one
2019-01-11T09:27:08 < dongs> yes, i read that
2019-01-11T09:27:25 < dongs> its MOSI in master mode
2019-01-11T09:27:54 < qyx> then go on and read transmit only mode
2019-01-11T09:28:00 < qyx> Simplex communications
2019-01-11T09:28:08 < qyx> Transmit-only mode (RXONLY=0): The configuration settings are the same as for full-
2019-01-11T09:28:11 < qyx> duplex. The application has to ignore the information captured on the unused input pin.
2019-01-11T09:28:14 < qyx> This pin can be used as a standard GPIO.

2019-01-11T09:44:45 < dongs> and just switch slave to 3 wire
2019-01-11T09:44:52 < dongs> and dont give a shit about sdo pin actually beign connected
2019-01-11T09:46:21 < qyx> in SPI, both the masterna and slave don't give a shit about spi pins being connected or not
2019-01-11T09:46:26 < qyx> except CS and SCK
2019-01-11T09:46:27 < dongs> yes im aware
2019-01-11T09:46:39 < dongs> anyway, this will need to be cut on pcb for real test
2019-01-11T09:46:54 < qyx> so I don't get how can you have any problems with it
2019-01-11T09:46:56 < dongs> i think the problme is spi slave device (while in low power mode) is injecting shit into STM via it's SDO pin
2019-01-11T09:47:11 < dongs> stm => standby, so everythign is highz
2019-01-11T09:47:15 < dongs> or so it should be
2019-01-11T09:47:23 < qyx> do there is electrical problem, not sw one?
2019-01-11T09:47:32 < dongs> well, sw is also there
2019-01-11T09:47:39 < dongs> i can't make stm actually do anything useful in 3 wire spi mode.
2019-01-11T09:47:48 < qyx> and setting the sdo/miso to analog input?
2019-01-11T09:47:48 < dongs> so i just put it back into 4 wire and not care bout reading status back
2019-01-11T09:48:00 < dongs> i just don't configure it but yeah i'll do that aswell
2019-01-11T09:50:07 < zyp> aandrew, maybe they have different versions of the core?

2019-01-11T10:37:15 < dongs> but in my setup i can't separate them anyway cuz vddio can't be higher than vcc+0.1
2019-01-11T10:37:28 < dongs> but vdd here is 2.8V and i/o is (when shit is powered up) 3.3V
2019-01-11T10:37:37 < dongs> when its in standby, 3.3V domain is completely off

2019-01-11T10:45:09 < PeterM> anyone here hand draw schematics and write down math on paper when just "thinking" of circuits?
2019-01-11T10:45:24 < zyp> yeah?
2019-01-11T10:46:26 < ds2> yep
2019-01-11T10:46:27 < PeterM> what kind of paper do you use? ruled? grid? dotted? plain?
2019-01-11T10:46:36 < ds2> cad just interferes with thinking
2019-01-11T10:47:11 < zyp> whatever is conveniently available
2019-01-11T10:47:27 < zyp> on my work desk I got a pile of post-its
2019-01-11T10:47:41 < ds2> or even back of envelopes
2019-01-11T10:47:54 < zyp> yes
2019-01-11T10:48:10 < PeterM> fair enough - i was asking because my current go to book is almost full (its just plain, reasonably heavy paper) and thinking of if there is any improvements
2019-01-11T10:48:59 < ds2> notebooks have their place

2019-01-11T10:52:59 < PeterM> yeah, i used to use envelopes and postits but i found that kinda stuff ends up making your desk messy
2019-01-11T10:53:29 < PeterM> its easier to keep track of stuff in a notebook too
2019-01-11T10:53:57 < PeterM> im mainly interested in if you think gridded or dotted paper would be better than plain
2019-01-11T10:54:24 < zyp> I used to use gridded

2019-01-11T10:55:39 < PeterM> yeah, im not keen on ruled, its is a bit annoying when drawing schematics
2019-01-11T10:55:53 < Haohmaru> i use MSPaint
2019-01-11T10:56:09 < zyp> Haohmaru, :)
2019-01-11T10:56:22 < Haohmaru> if i really need paper, i take old calendar sheets
2019-01-11T10:56:57 < PeterM> Haohmaru i used to too, but as soon as you need to write anything it kills the flow
2019-01-11T10:57:08 < PeterM> paint is fine for drawings though
2019-01-11T10:57:15 < Haohmaru> yeah, writing text with teh pencil sux

2019-01-11T11:29:34 < PeterM> i figured A5 would be big enough to need to stick in a bag or case so i may aswell use an A4

2019-01-11T11:34:47 < qyx> I also have a pack of Stabilo fineliners with it
2019-01-11T11:36:36 < zyp> I used to use gridded A4
2019-01-11T11:36:58 < ds2> i am experimenting with different apps on phones
2019-01-11T11:37:06 < PeterM> ahh, yeah, stabilo fineliners are great, i had forgotten about them
2019-01-11T11:37:23 < kakimir> would you use plugable terminal block headers for tester - jig connections?
2019-01-11T11:37:35 < PeterM> i might grab one of both (gridded and dotted), they're cheap enough
2019-01-11T11:37:53 < PeterM> ds2 i almost bought one of those sony e-paper notebook things
2019-01-11T11:38:06 < PeterM> but i couldnt jsutify the $1k
2019-01-11T11:38:09 < ds2> e-paper does not cut it. the lag is annoying

2019-01-11T11:39:02 < zyp> ds2, have you tried remarkable? according to what I've heard they've focused a lot on minimizing lag
2019-01-11T11:39:16 < ds2> how do you manage revisions with a pen?
2019-01-11T11:39:32 < ds2> zyp: no, I was very tempted but that thing is $$$$$
2019-01-11T11:39:43 < zyp> yeah
2019-01-11T11:39:59 < ds2> I had a cheap android eReader repurposed with to run regular apps
2019-01-11T11:40:13 < PeterM> ds2 cross out, make changes - once enough changes are made, i re-draw
2019-01-11T11:40:33 < zyp> I haven't tried it myself either, but I've talked to some of the developers
2019-01-11T11:40:44 < ds2> PeterM: doesn't that make it rules/grids agnostic?
2019-01-11T11:41:01 < ds2> if you cross out enough, rules/grids won't do anything
2019-01-11T11:41:22 < PeterM> zyp i was tossing up between remarkable and sony digital paper, but both are $$$$
2019-01-11T11:41:31 < ds2> i wind up working at random place a lot and a phone seems to be what I have on me
2019-01-11T11:41:42 < zyp> I actually interviewed with them a couple of years ago, but then I ended up getting a good offer elsewhere that I jumped on
2019-01-11T11:42:18 < ds2> i wonder how locked down is the remarkable stuff
2019-01-11T11:42:24 < PeterM> ds2 it is still think it would be nice to have something regular to align things to,
2019-01-11T11:42:35 < zyp> I think it's fairly hackable
2019-01-11T11:43:06 < ds2> by the time I want it neat, my thoughts are organized enough to do it in cad
2019-01-11T11:43:35 < ds2> IMO - grids are more suitable for mechanical stuff where there is a notion of scale
2019-01-11T11:43:42 < ds2> prehaps when roughing out layouts
2019-01-11T11:44:48 < PeterM> nah, i like my hand drawn schematics to be very readable, i find it makes it easier to find issues if you arent trying to decipher your own schematic
2019-01-11T11:45:08 < PeterM> grids are very good for mechanical drawings, yes
2019-01-11T11:45:23 < ds2> how complex are your hand drawn schematics?
2019-01-11T11:47:56 < PeterM> they vary from jsut small hand full of discrete components to say, 4 16 pin ics and associated passives and discretes
2019-01-11T11:47:57 < rajkosto> i like this module better https://images.sshnuke.net/2019-01-11_10-47-50_BnN1tgJSn.png
2019-01-11T11:48:07 < rajkosto> cant break
2019-01-11T11:49:15 < ds2> oh that's why you can afford to have neat hand schematics
2019-01-11T11:49:32 < ds2> i usually just have pieces and  glue them together when they get to the cad stage
2019-01-11T11:50:48 < PeterM> its all mostly analog stuff, so it rarely has busses and shit, its like fet drivers, current sense amps, switching controllers, filters etc
2019-01-11T11:51:48 < PeterM> complexity also kinda varies depending on how "into it" i get
2019-01-11T11:53:16 < PeterM> fig 32 in this http://www.ti.com/lit/an/slua143/slua143.pdf is about the average complexity i would do on paper
2019-01-11T11:54:08 < ds2> that's more then what I'd do

2019-01-11T12:11:30 < qyx> on a different topic, having a PDM microphone and a STM32 wihtout the new DFSDM peripheral
2019-01-11T12:11:43 < qyx> is it more sane to use I2S or SPI to capture the btstream?
2019-01-11T12:12:08 < qyx> SPI looks more straightforward and easier
2019-01-11T12:14:23 < karlp> aandrew: re usb on f7, as zyp said, there doesn't _appear_ to be any differences with f4, but at least for me, using the f4 usb code doens't work on my f756 disco, but it does for other people allegedly. so... something's fucky with f7 on something...
2019-01-11T12:17:30 < karlp> PeterM: I use an a5 plain paper notebook too, but it just stays on my desk at work.

2019-01-11T12:18:20 < PeterM> what. PDM microphone, I2S, SPI? i assume you mean MEMS microphone? and i'd probably use SPI if thats the case

2019-01-11T13:51:53 < Thorn> they're all good stuff
2019-01-11T13:52:25 < qyx> didn't try yet, but I can confirm TPS62825 works
2019-01-11T13:52:34 < qyx> with 1V8 out
2019-01-11T13:52:45 < zyp> oh, cute
2019-01-11T13:52:54 < dongs> sneeze and i ts gone
2019-01-11T13:52:56 < zyp> no feedback divider and shit
2019-01-11T13:53:41 < zyp> (on 177)
2019-01-11T13:54:34 < dongs> you can use it to make negative supply too
2019-01-11T13:55:06 < dongs> http://www.ti.com/lit/an/slva542a/slva542a.pdf
2019-01-11T13:56:02 < zyp> you can hook most bucks like that
2019-01-11T13:56:06 < dongs> ah ok
2019-01-11T13:56:48 < zyp> it's basically the same thing
2019-01-11T13:58:27 < zyp> normally a buck sits on GND, takes VIN and gives you a lower VOUT
2019-01-11T13:59:20 < zyp> to make a negative voltage, you instead reference it from -VOUT, so you get an input voltage between VIN and -VOUT and it regulates down to a lower output voltage between GND and -VOUT
2019-01-11T14:03:05 < zyp> dongs, did you see my network tweet yesterday?

2019-01-11T14:07:37 < zyp> eventually
2019-01-11T14:08:58 < zyp> short term I don't need to have every port hooked up, so I'm just gonna make do with the one I have

2019-01-11T14:17:37 < zyp> yeah, I'm very happy with how it's turning out
2019-01-11T14:17:53 < qyx> 500W poe output, you can mount poe camera on every port
2019-01-11T14:19:51 < zyp> well, yeah, it's way more than I need
2019-01-11T14:22:04 < zyp> but still, I need something that has a couple 10G ports, a couple PoE ports, and a bunch of plain 1G ports
2019-01-11T14:22:43 < qyx> what do you n eed 10G for?
2019-01-11T14:22:44 < zyp> I haven't seen anything else that can do all of those in a single affordable device

2019-01-11T14:23:57 < zyp> idk, the small one I've got works fine
2019-01-11T14:24:21 < sync> we had one of the cloudswitches and it would eat dhcp acks
2019-01-11T14:24:33 < zyp> which one?
2019-01-11T14:24:34 < qyx> no single mikrotik shitshow here and I used tens of them, starting with old RB133
2019-01-11T14:25:18 < zyp> I've had the small one for around three years now, never a problem
2019-01-11T14:25:21 < qyx> mhm, actually I remember one firmware flash problem on RB1200
2019-01-11T14:25:40 < qyx> it always died after ~month
2019-01-11T14:27:15 < qyx> interesting that ST recommends 10n+1u on VDDA on a L4
2019-01-11T14:27:25 < dongs> ?
2019-01-11T14:27:32 < dongs> dont they always
2019-01-11T14:27:39 < sync> I think some crs326 24g 2s was it
2019-01-11T14:27:40 < qyx> wasn't it 100n+1u?
2019-01-11T14:27:55 < dongs> they probly want less noise onvdda

2019-01-11T17:22:35 < Ecco> Yep

2019-01-11T17:22:50 < Laurenceb_123> didnt even know it supported that, nice

2019-01-11T17:23:15 < Ecco> Supposedly
2019-01-11T17:23:25 < Laurenceb_123> so it can just run straight from the QSPI?
2019-01-11T17:23:31 < Ecco> yep

2019-01-11T17:50:42 < Laurenceb_123> this is the standard design https://www.gearslutz.com/board/attachments/newbie-audio-engineering-production-question-zone/400864d1401424649-how-connect-unpowered-3-5-mm-microphone-rme-fireface-ufx-computer-mic-input-circuit.jpg
2019-01-11T17:52:58 < Laurenceb_123> I hate audiophools
2019-01-11T17:53:27 < BrainDamage> that's a standard design
2019-01-11T17:53:37 < BrainDamage> the supply is to power electret microphones
2019-01-11T17:53:50 < BrainDamage> that have an internal transistor hardwired to the mic input
2019-01-11T17:54:36 < BrainDamage> the 5V biases the transistor, hence why there's the resistor too
2019-01-11T17:54:55 < BrainDamage> it's a common feature of many pc audio cards too
2019-01-11T17:56:34 < catphish> unless, i'm missing something, "phantom power to mic on 3.5mm TRS jack" makes perfect sense, a TRS jack with a DC voltage to power microphones plugged into it
2019-01-11T17:57:38 < jpa-> Ecco: yeah, quad-spi memory mapped part goes through cache, peripheral registers go directly
2019-01-11T17:57:39 < dongs> also its QFN4x4 i guess

2019-01-11T18:04:40 < qyx> or how is it called properly
2019-01-11T18:05:29 < rajkosto> a hub ?
2019-01-11T18:05:47 < qyx> what the hell is it
2019-01-11T18:06:04 < Laurenceb_123> ok looks like sennheiser send voltage down the mic line https://sennheiseruk.happyfox.com/kb/article/104-ew-plug-pin-configuration/
2019-01-11T18:06:16 < rajkosto> is stm32 integrated pullup enough for buttons ?
2019-01-11T18:07:19 < rajkosto> you can set PU on gpios
2019-01-11T18:07:27 < rajkosto> that good enough for button inputs ?
2019-01-11T18:07:30 < dongs> yes of course it is
2019-01-11T18:07:31 < qyx> yes
2019-01-11T18:07:32 < dongs> why wouldtn it be
2019-01-11T18:07:50 < dongs> anyway, now that i saw usb going to it i lost interst in it
2019-01-11T18:07:52 < dongs> its not cpld
2019-01-11T18:08:02 < dongs> whatever the fuck it is, probly a usb switch or somethign
2019-01-11T18:08:03 < rajkosto> because stuff like 100K pullups can be too little sometimes
2019-01-11T18:08:17 < rajkosto> buttons
2019-01-11T18:08:24 < dongs> look in datasheet.
2019-01-11T18:08:30 < dongs> internal pu is like 30-50k iirc
2019-01-11T18:09:41 < kakimir> there is IP+ and IP- pins in hall current sensor
2019-01-11T18:10:41 < kakimir> it doesn't really describe them much
2019-01-11T18:11:09 < kakimir> so output grows in positive direction as there is current from IP+ to IP-?
2019-01-11T18:11:55 < kakimir> ACS724
2019-01-11T18:14:32 < kakimir> yes
2019-01-11T18:14:39 < kakimir> queiscent voltage
2019-01-11T18:14:49 < kakimir> but I use unidir version of the chip

2019-01-11T18:20:54  * Laurenceb_123 is obviously a microphone permanoob
2019-01-11T18:21:24 < Laurenceb_123> if I have an electret with 50µA current, 4.4k impedance, and 1.3v voltage, what do i do?
2019-01-11T18:23:31 < jpa-> you disregard all the parameters and just connect it into a microphone preamp
2019-01-11T18:23:37 < Laurenceb_123> keek

2019-01-11T18:23:47 < Laurenceb_123> arg wtf
2019-01-11T18:24:19 < Laurenceb_123> so I connect it to 1.3v using a 4.4k resistor and it draws 50µA ?
2019-01-11T18:24:35 < Laurenceb_123> audiophoools are incapable of talking sense
2019-01-11T18:25:05 < jpa-> that datasheet says operating voltage is 1.5 to 10V, so you connect it to something like that and the output voltage will be approx 1.3V
2019-01-11T18:25:31 < jpa-> though that datasheet seems different on all specs than what you said
2019-01-11T18:26:01 < jpa-> but basically any electret you can connect with ~2kohm resistor to +3.3V and get something
2019-01-11T18:26:57 < Laurenceb_123> sorry I was just using that datasheet as an example
2019-01-11T18:27:02 < Laurenceb_123> I only have specs for my mic

2019-01-11T18:52:24 < jadew> jeez... found an issue with fusion (on the todo list since 2015)
2019-01-11T18:52:36 < jadew> you can't add a hole table on the drawings
2019-01-11T18:52:51 < jadew> how am I going to go with this to the machinist I don't know
2019-01-11T18:53:01 < jadew> I guess I'll have to write the coordinates by hand
2019-01-11T18:53:30 < jadew> dongs, wth is that?
2019-01-11T18:55:12 < dongs> looks like ellen feiss 2019
2019-01-11T18:55:36 < jadew> Cracki, yeah
2019-01-11T18:56:07 < jadew> not really, I'm going to take it to an old school guy
2019-01-11T18:56:17 < jadew> so he's going to manually mill it
2019-01-11T18:56:48 < jadew> I'll have to hand him an actual piece of paper with the coords
2019-01-11T18:57:19 < jadew> I tried to show their positions on an extra drawing, but they're too many
2019-01-11T18:57:32 < jadew> it would be simpler for the machinist to have a table
2019-01-11T19:00:18 < jadew> yeah, it's still on the road map since 2015
2019-01-11T19:00:34 < jadew> in the meantime the only table function gives you a table which is not editable
2019-01-11T19:00:53 < jadew> not me
2019-01-11T19:01:08 < jadew> neat
2019-01-11T19:02:06 < jadew> yeah, with the parts on the sheet

2019-01-11T20:21:43 < mawk> I have one on my desk, it feels classy
2019-01-11T20:21:50 < mawk> it's heavy, metallic, nice blue leds
2019-01-11T20:21:58 < mawk> perfect for pressing my papers
2019-01-11T20:22:17 < Laurenceb_123> RTC broken, battery charger broken, battery power broken, sleep mode broken
2019-01-11T20:22:31 < Laurenceb_123> auto wakeup stuff broken
2019-01-11T20:22:36 < Laurenceb_123> PMIC broken
2019-01-11T20:22:47 < specing> BBB = Broken, Broken and Broken?
2019-01-11T20:22:51 < Laurenceb_123> aparent from that its good
2019-01-11T20:22:53 < Laurenceb_123> yup
2019-01-11T20:23:20 < Laurenceb_123> I fixed mine but it looks like a rats nest and has several holes drilled through the pcb
2019-01-11T20:24:27 < mawk> I have one broken
2019-01-11T20:24:31 < mawk> something something capacitor says the internet
2019-01-11T20:24:43 < mawk> so I gave it back to the teacher so that he could give me a new one
2019-01-11T20:24:52 < mawk> "you will pay it back with your own money !!" he said with a red face
2019-01-11T20:25:04 < mawk> so I emailed him the forum links of people having dead bbb for no reason
2019-01-11T20:27:55 < Laurenceb_123> BBB would be very cool if they fixed it, actual working embedded lunix
2019-01-11T20:28:03 < Laurenceb_123> >implying embedded lunix is a good idea
2019-01-11T20:29:00 < mawk> yeah I'm not a fan of this in the first place
2019-01-11T20:29:03 < specing> it is a good idea if the drivers are done well and mainlined
2019-01-11T20:29:04 < mawk> but bbb has coprocessor !
2019-01-11T20:29:07 < mawk> so it's not embedded lunix
2019-01-11T20:29:09 < specing> which is almost never the case
2019-01-11T20:29:13 < mawk> it's lunix controlling real embedded
2019-01-11T20:29:21 < specing> so I avoid embedded linux like the plague
2019-01-11T20:29:46 < mawk> I thought you'd mention the software Laurenceb_123 
2019-01-11T20:30:06 < mawk> the sloppy handwritten bash scripts doing critical init work, the dirty arborescence in /boot, the outdated doc in various config file
2019-01-11T20:30:11 < specing> mawk: every x86 machine has at least one coprocessor, your point is invalid
2019-01-11T20:30:21 < mawk> but judging by your coding style I'd have guessed that doesn't bother you
2019-01-11T20:30:36 < mawk> you can't use it without being intel engineer or blackhat sensei specing 
2019-01-11T20:30:39 < mawk> yours is invalid
2019-01-11T20:30:49 < specing> you can, its documented
2019-01-11T20:31:00 < mawk> where
2019-01-11T20:31:06 < specing> well, some are. Some such as the embedded controller
2019-01-11T20:31:07 < Laurenceb_123> in cancer docs
2019-01-11T20:31:12 < mawk> ah
2019-01-11T20:31:20 < mawk> I thought you were talking about the IME
2019-01-11T20:31:42 < Laurenceb_123> if I was working on something serious I'd unironically run VXWorks
2019-01-11T20:31:46 < specing> no, but I'd be pleased if IME was open
2019-01-11T20:31:57 < specing> instead I have to buy 10 year old thinkpads for Libreboot
2019-01-11T20:32:19 < mawk> why Laurenceb_123 
2019-01-11T20:32:37 < Laurenceb_123> mawk: because it's a proper documented rtos
2019-01-11T20:32:45 < Laurenceb_123> or just use chibios
2019-01-11T20:32:55 < mawk> freertos is documented enough for my school to give classes in it
2019-01-11T20:33:13 < mawk> they did vxworks previously
2019-01-11T20:33:18 < Laurenceb_123> or that, but I find it a bit cancerous
2019-01-11T20:33:21 < mawk> but I suspect they didn't want to pay the license any further

2019-01-11T20:44:46 < mawk> it's cheaper to buy in bulk
2019-01-11T20:44:52 < mawk> also nicotine juice is banned in the EU now
2019-01-11T20:45:00 < antto> oh?
2019-01-11T20:45:02 < mawk> so I imported very strongly dosed nicotine juice from the US in one big package to have enough for years

2019-01-12T00:08:20 < kakimir> how many gigabits?
2019-01-12T00:09:43 < zyp> all the gigabits
2019-01-12T00:09:51 < specing> zyp: 0/10 low effort
2019-01-12T00:09:58 < zyp> :(
2019-01-12T00:10:04 < specing> no coloured wires and no serial port
2019-01-12T00:10:14 < kakimir> all them!
2019-01-12T00:10:26 < specing> all my network cabling is made of green wires
2019-01-12T00:10:26 < zyp> specing, serial what?
2019-01-12T00:10:49 < specing> it looks better than all-gray, but I have the same mono-colour problem now
2019-01-12T00:10:55 < karlp> does green make them go faster? or is it just more environmentally sound?Ð
2019-01-12T00:11:06 < specing> it makes them more eye-friendly
2019-01-12T00:11:45 < zyp> I actually did a bunch of searching for colored cat6, my original plan was to run two in each conduit and I wanted different colors on them
2019-01-12T00:12:11 < kakimir> green color makes them green
2019-01-12T00:12:24 < zyp> but everything I found was either grey or expensive or CCA bullshit

2019-01-12T00:17:58 < karlp> zyp: what's "CCA bullshit"?
2019-01-12T00:17:59 < Steffanx> Why is it relevant when you hardly ever see it. When you use something like zyp does?
2019-01-12T00:18:07 < specing> Steffanx: I've lost hope
2019-01-12T00:18:10 < zyp> karlp, copper clad aluminum
2019-01-12T00:18:19 < karlp> does that matter for in wall stuff?
2019-01-12T00:18:34 < zyp> CCA? yeah, it's shit
2019-01-12T00:19:28 < zyp> I mean, I don't have any firsthand experience, but I'm surprised it even exists
2019-01-12T00:20:05 < Steffanx> Its cheaper and usually works
2019-01-12T00:20:10 < Steffanx> Until it doesnt.
2019-01-12T00:20:37 < zyp> it's apparently not standards compliant and thin aluminum wires have shit mechanical properties
2019-01-12T00:21:26 < zyp> and I'm surprised it's so much cheaper to make copper clad aluminum wires that it's worthwhile to make network cables of it
2019-01-12T00:21:27 < Steffanx> And higher resistance > possible issues with PoE?
2019-01-12T00:21:46 < zyp> that too, but I doubt that's a major concern
2019-01-12T00:22:19 < zyp> it's mostly the mechanical properties that steers me away from it
2019-01-12T00:23:39 < zyp> also, Steffanx has a point, my cables aren't gonna be very visible once I got the switch and router mounted above them in the rack

2019-01-12T03:11:11 < sync> that is why you assume the router to be the enemy
2019-01-12T03:11:39 < BrainDamage> ^^^^
2019-01-12T03:11:46 < BrainDamage> your network ends before the router
2019-01-12T03:12:10 < jadew> yeah, I should probably do something about that
2019-01-12T03:21:47 < BrainDamage> you just have your own router before the isp
2019-01-12T03:21:52 < BrainDamage> isp's*
2019-01-12T03:22:13 < BrainDamage> then they'll just hit a brick (fire)wall if they try to access your network
2019-01-12T03:22:30 < jadew> I used to, but port forwarding is easier with out it
2019-01-12T03:22:52 < jadew> the important stuff on the network behaves like it's on the internet anyway
2019-01-12T03:23:32 < jadew> so at least there's that, but yeah, I guess it's not a bad idea to get back to how things used to be
2019-01-12T03:24:15 < jadew> might need a more powerful router, I think another reason I gave up on that arrangement was because I wasn't getting maximum throughput
2019-01-12T03:25:27 < BrainDamage> consider also that ipv6 has no natting
2019-01-12T03:25:59 < BrainDamage> so your internal network, if ipv6 enabled, gets exposed to the interwebs
2019-01-12T03:26:39 < BrainDamage> I bet a ton of shit networking and security policies will be exposed as ipv6 gets more common
2019-01-12T03:26:57 < BrainDamage> read: you shouldn't rely on natting as firewall, you'll need explicit firewall rules

2019-01-12T03:33:29 < jadew> that's indeed good to keep in mind
2019-01-12T03:35:19 < sync> well you *can* nat v6
2019-01-12T03:35:26 < sync> you might not want to do so, but you can
2019-01-12T03:37:04 < BrainDamage> it's not the configuration of nearly every ipv6 device around, you'll need to go out your way to do it
2019-01-12T03:37:26 < BrainDamage> so while default ipv4 hypothesis is nat, the opposite for ipv6

2019-01-12T10:24:21 < dongs> it uses some old directfb thats been vendor patched i guess to add all this extra shit

2019-01-12T10:58:55 < zyp> or just apiptr->FuncName(args)
2019-01-12T11:02:52 < PaulFertser> DirectFB is in C, so no implicit "this" pointer.
2019-01-12T11:04:39 < zyp> wait, so apiptr is a pointer to a struct, containing a function pointer named FuncName?
2019-01-12T11:05:39 < zyp> in that case, there shouldn't exist more than one instance of the struct, so passing it to the function seems kinda pointless
2019-01-12T11:12:40 < Thorn> in C, every instance of an object will contain pointers to all its methods
2019-01-12T11:14:01 < PaulFertser> zyp: see e.g. https://wiki.gumstix.com/index.php/How_to_get_started_with_DirectFB. , it's not only main interface but also arbitrary number of "surfaces".

2019-01-12T11:25:33 < PaulFertser> Apparently DirectFB allows all operations to be performed via some proxy, hence dynamic dispatch.
2019-01-12T11:28:40 < PaulFertser> DirectFB allows running multiple applications on same screen, and it also allows to use the API remotely.

2019-01-12T11:35:25 < dongs> PaulFertser: so i should be able to draw on top of shit despite some app already using fb?
2019-01-12T11:36:18 < dongs> anyway ill look into it later
2019-01-12T11:36:30 < dongs> it takes like 20 clicks to exfiltrate built app from rageberry and copy to stb

2019-01-12T11:37:44 < PaulFertser> dongs: "Running multiple DirectFB applications at the same time" in README says it needs a specific build

2019-01-12T11:44:40 < dongs> probly some #ifdef MULTI shit in headers tho
2019-01-12T11:44:43 < dongs> that disables stuff
2019-01-12T11:44:56 < dongs> and then the app uses libs taht are installed on stb

2019-01-12T11:52:14 < PaulFertser> dongs: btw, I think if you can somehow make that original application not touch a specific part of the screen then you should be able to draw directly into framebuffer by whatever means you prefer.
2019-01-12T11:53:00 < dongs> im gonna reverse a couple more bin and see how they startup the directfb shit

2019-01-12T13:01:14 < PeterM> the other option was just a gear hold paddle/button, since its an auto would be nice for thrashing it
2019-01-12T13:10:24 < zyp> dongs, the what?
2019-01-12T13:11:00 < zyp> D/B mode selection?
2019-01-12T13:11:07 < PaulFertser> For driving without legs? I fail to see how that can be more easy/lazy.

2019-01-12T14:15:17 < Steffanx> Imagine doing it without hands (and no not a self-driving car) PaulFertser. A foot steer is actually a thing in the dutchland.
2019-01-12T14:15:46 < dongs> zyp wat?
2019-01-12T14:16:53 < PaulFertser> Steffanx: sounds dangerous, especially to the cyclists and motobikers...
2019-01-12T14:18:49 < Steffanx> Idk PaulFertser, when you're used it it... i wonder if it makes a real differents
2019-01-12T14:19:11 < Steffanx> http://www.mobiel-prototypebouw.nl/images/aanpassingen-bestelbus-auto/vlak-voetstuur-02.jpg bad pic, but .. you get the idea.
2019-01-12T14:20:10 < PaulFertser> Heh. I hope they do not drive aggressively then.
2019-01-12T14:22:17 < dongs> zyp, if youre talkign about gas/brake shit, you can get official (or aftermarket?) thingies where you can control gas/brake by paddles-like thing on the steering wheel. for people who drive wihtout legs or whatever.
2019-01-12T14:23:30 < Steffanx> it doesnt even look that hard PaulFertser https://youtu.be/4fDAo2MN92Q?t=142

2019-01-12T14:35:59 < sync> there is also the system franz

2019-01-12T14:36:16 < sync> that is even stranger
2019-01-12T14:36:22 < sync> but makes more sense anatomically
2019-01-12T14:36:22 < jpa-> i wonder why it is a wheel and not just direction pedals like in an aircraft
2019-01-12T14:36:35 < sync> because that is more hassle to make
2019-01-12T14:36:47 < sync> you still have to work with a regular steering boxxy
2019-01-12T14:36:51 < PaulFertser> And because you need the other leg to control throttle and brakes.
2019-01-12T14:37:15 < jpa-> aircraft pedals usually have brakes controlled with the tip of your foot
2019-01-12T14:37:20 < jpa-> (toes? ;)
2019-01-12T14:37:38 < PaulFertser> Also, I guess control precision wouldn't be enough.
2019-01-12T14:39:38 < PaulFertser> You have several times 360 degrees with a regular steering wheel. Hm, but otoh motorbike steering works just fine. No idea how to explain that.

2019-01-12T14:41:31 < sync> you don't have very high steering forces in a motorcycle
2019-01-12T14:41:52 < sync> and you don't need very large inputs most of the time
2019-01-12T14:42:14 < sync> as you cannot turn the handlebar suddenly to one side like you can in a car
2019-01-12T14:55:37 < PaulFertser> Steering forces are not too relevant with modern power steering. Large inputs are not mostly needed with the cars too. Rally racers use about 540 degrees while regular cars might have 1080+ .

2019-01-12T16:07:07 < dongs> so uh what is modern way to work with spartan6, surely tehre's something better than isntalling ISE in vmware..
2019-01-12T16:09:12 < Thorn> there is something better: downloading a VM with preinstalled ISE
2019-01-12T16:09:47 < Thorn> I even got it to work with platform cable connected to the host but only on a mac
2019-01-12T16:10:16 < dongs> really?
2019-01-12T16:10:39 < specing> no opensores, closedsores!
2019-01-12T16:11:14 < dongs> Thorn: wehre?

2019-01-12T16:11:45 < Thorn> there is an opensores synthethis toolkit (supporting much more modern verilog than ISE too but not VHDL) but afaik nobody is working on adding s-6 support to it
2019-01-12T16:11:54 < dongs> yeah no.
2019-01-12T16:11:56 < dongs> i want shit that works
2019-01-12T16:12:10 < dongs> i dont know enough about this shit to fuck with it, i just want working stuff
2019-01-12T16:12:39 < Thorn> you may also try this https://stackoverflow.com/questions/48219896/ise-design-suite-14-7-ise-spartan-6-virtual-machine-vm-for-windows-10
2019-01-12T16:13:16 < dongs> thats the old trick that i recall failed some way otr another
2019-01-12T16:13:18 < dongs> ill jsut do vm
2019-01-12T16:13:36 < dongs> oh fucking gross
2019-01-12T16:13:38 < dongs> that VM is lunix
2019-01-12T16:13:41 < dongs> fuck
2019-01-12T16:13:51 < Thorn> of course, what else
2019-01-12T16:13:55 < dongs> at that point i might as well just install win7 and install ISE myself...
2019-01-12T16:14:01 < dongs> well iw anted shit that WORSK
2019-01-12T16:14:02 < Thorn> did you expect licensed wiendows inside?
2019-01-12T16:14:14 < Thorn> it works
2019-01-12T16:14:18 < dongs> why would they need to be licensed
2019-01-12T16:14:21 < Thorn> it's freaking slow but works
2019-01-12T16:14:25 < specing> ISE works better on Linux than on windows
2019-01-12T16:14:39 < dongs> we must have wildly different definitions of "works"
2019-01-12T16:16:06 < malinus> Will stm32 ever start making high-end cheap m7's with no flash or will it just die to nxp?
2019-01-12T16:16:22 < dongs> whats the big deal about m7
2019-01-12T16:16:41 < Thorn> there is h750 iirc with a little internal flash
2019-01-12T16:16:43 < malinus> cheap, fast (more cache etc.).
2019-01-12T16:16:44 < specing> malinus: considering that you can get a chinese cortex-a* for the price of an m4...
2019-01-12T16:18:25 < malinus> yeah half the price of stm32f4, not all m4's
2019-01-12T16:21:13 < malinus> I doubt any western companies use counterfeit chips anyway. At least none who produce volume. So it's not a fair comparison.
2019-01-12T16:21:29 < specing> counterfeit?
2019-01-12T16:21:49 < specing> stuff like allwinner and rockchip
2019-01-12T16:22:03 < specing> they don't do counterfeits of western chips
2019-01-12T16:22:13 < specing> and mediatek
2019-01-12T16:22:48 < dongs> yeah they just stuff them full of stolen IP
2019-01-12T16:22:58 < dongs> to the point where they don't even have docs for the shit they put in there
2019-01-12T16:23:04 < dongs> like allwhiner has a mpeg2ts input port
2019-01-12T16:23:11 < dongs> thats completely undocumented
2019-01-12T16:24:23 < Thorn> how do they manage to synthesize all of it without any help from IP vendors?
2019-01-12T16:24:37 < dongs> shrug
2019-01-12T16:28:08 < dongs> oh i already had a winxp vm
2019-01-12T16:28:09 < dongs> with ISE
2019-01-12T16:28:10 < dongs> in it
2019-01-12T16:29:08 < specing> lol
2019-01-12T16:29:38 < malinus> specing: meh, cheapest allwinner cortex-a is still $2+
2019-01-12T16:29:47 < dongs> and cheapest m7 is way more
2019-01-12T16:29:49 < dongs> your point???
2019-01-12T16:30:17 < malinus> dongs: no it isn't.
2019-01-12T16:30:29 < malinus> and that's my point
2019-01-12T16:30:47 < dongs> its not?
2019-01-12T16:30:55 < dongs> well please link me to some cortex m7s for <$2
2019-01-12T16:33:39 < malinus> well all the nxp rt's series. You can get them all for less than $2 in 1M+ volume.

2019-01-12T16:36:41 < dongs> the pic matches, im just looking for schematic or whatever
2019-01-12T16:36:47 < dongs> but looks like the jtag port is standard platform cable thing
2019-01-12T16:37:07 < dongs> and led pin#s are labeled

2019-01-12T16:46:54 < dongs> and it seems to be working OK

2019-01-12T17:18:39 < dongs> you better pull the gate to the state you want it to be by default
2019-01-12T17:18:42 < dongs> i.e. up or down
2019-01-12T17:18:51 < bitmask> yea I did that
2019-01-12T17:18:57 < bitmask> its pulled down
2019-01-12T17:18:58 < dongs> then who cares.
2019-01-12T17:19:00 < bitmask> ok
2019-01-12T17:19:25 < dongs> in my current shitty lowpower design thats what i did, i ahve a fet that gates boost converter + other shit
2019-01-12T17:19:31 < dongs> that stm turns on after wake up
2019-01-12T17:19:41 < dongs> and when it goes to standby, stm pin goes highz, and pulldown turns shit off
2019-01-12T17:19:54 < bitmask> I shoulda done that for my bucks, oh well
2019-01-12T17:23:42 < dongs> not all converters will actually disconnect in from out
2019-01-12T17:23:43 < dongs> when disabled
2019-01-12T17:24:02 < dongs> shit will be just vin - coil R - vout
2019-01-12T17:25:16 < bitmask> well I guess one always has to be on when the power switch is on, thats what powers the mcu, but the second I was between using a mosfet on the input or the output and opted for the output because I wasn't sure if I wanted to do some pwm with it, it wont be a big deal though

2019-01-12T18:29:50 < dongs> its just not worth my time
2019-01-12T18:29:52 < bitmask> yea mine is just the standard ratcheting one but the dies are so thick, if I use thick wire then the crimper just destroys the wire
2019-01-12T18:32:38 < englishman> yeah NEVER do that shit
2019-01-12T18:32:47 < englishman> just buy some precrimped and shove them into JSTs

2019-01-12T20:35:46 < jpa-> englishman: depending on speed, slap a LVDS deserializer chip on STM32 DCMI interface?
2019-01-12T20:36:22 < englishman> ah yeah, considered a cortex-m for about 5 minutes but most of these sensors are 480mbit+ per channel
2019-01-12T20:36:34 < englishman> up to 600mbit/s
2019-01-12T20:36:49 < jpa-> ah
2019-01-12T20:37:03 < englishman> interface has to be usb3 as well
2019-01-12T20:37:12 < Steffanx> englishman stopped assembling and got a shitload of time for pro-projects now?
2019-01-12T20:37:39 < englishman> the previous generation of this product is pushing 400mbyte/s+ over usb3 and this new one will be higher res and fps
2019-01-12T20:37:53 < zyp> sounds like what people will do fpga+fx3 for
2019-01-12T20:37:56 < englishman> yes although i still have some assembly to do :(
2019-01-12T20:38:00 < englishman> yes that is the previous gen
2019-01-12T20:38:06 < englishman> spartan6+fx3
2019-01-12T20:38:15 < englishman> but the fpga guys left
2019-01-12T20:38:29 < englishman> so it will be me hacking together some shit on a zynq
2019-01-12T20:38:29 < zyp> well, fpga+fx3 is gonna be the best solution still
2019-01-12T20:38:31 < englishman> rip, company
2019-01-12T20:38:38 < englishman> yes it looks like it
2019-01-12T20:38:58 < englishman> cool part is then i can put it together on some cool ass 10 layer
2019-01-12T20:39:04 < zyp> fun
2019-01-12T20:39:06 < englishman> and add fpga pro to the CV
2019-01-12T20:39:29 < englishman> but of course i should prevent that solution and 1-2 others
2019-01-12T20:39:47 < englishman> i.mx8 would be cool, as it will probably be used in another product as well
2019-01-12T20:40:10 < zyp> I worked on a 10L board once, idk how it went, the board went to fab right before my last day at that company :p
2019-01-12T20:40:27 < Steffanx> Does the company still exist?
2019-01-12T20:40:47 < jpa-> fx3 + deserializer chip (like SN65LV1224) might work also
2019-01-12T20:41:00 < zyp> I assume so, but they went bankrupt a year ago or something
2019-01-12T20:41:03 < jpa-> not as flexible as fpga but less coding to do
2019-01-12T20:41:48 < zyp> ah, june last year
2019-01-12T20:41:56 < englishman> i wonder if that would indeed be an option
2019-01-12T20:43:02 < zyp> as long as the data doesn't need any reformatting
2019-01-12T20:43:22 < jpa-> and as long as FX3 can meet your buffering needs
2019-01-12T20:43:54 < englishman> indeed there is a little arm9
2019-01-12T20:44:29 < englishman> hmm 100MHz gpios tho
2019-01-12T20:44:41 < englishman> no, buffering would definitely be needed

2019-01-12T23:12:39 < aandrew> I can't select any components on the embedded panels, and all I can pick up is the x,y of the embedded board
2019-01-12T23:12:46 < aandrew> so I guess I can calculate from there but that's... subpar

2019-01-12T23:32:02 < Steffanx> But the parts should be missing in the first place.
2019-01-12T23:32:12 < Steffanx> And the tap shouldnt leak :P

2019-01-12T23:32:39 < zyp> Steffanx, yeah, nobody should fuck up, ever
2019-01-12T23:32:55 < Steffanx> Yes, but ikea is known for missing parts.
2019-01-12T23:33:08 < zyp> that's not my experience
2019-01-12T23:33:18 < Steffanx> Hm in dutchland it is
2019-01-12T23:33:44 < zyp> are you speaking from firsthand experience or word of mouth?
2019-01-12T23:34:28 < Steffanx> Both. 
2019-01-12T23:35:12 < Steffanx> But based on a single sample personal experience 
2019-01-12T23:35:16 < zyp> I'm inclined to believe a lot of people complaining about missing parts managed to lose them themselves :p
2019-01-12T23:35:25 < Steffanx> So perhaps not completely fair
2019-01-12T23:36:01 < karlp> mawk: used ucos2 in uni, a few months back, seeing them mention it was now "free for makers" I signed up and downloaded it all,l was going to do some comparisons 
2019-01-12T23:36:25 < karlp> but it's a great big pile of unrneadable macros and old school code and I just decided I wasn't interested in spending the time on it.
2019-01-12T23:37:19 < zyp> are there any decent modern rtoses?
2019-01-12T23:37:35 < zyp> modern as a counterpoint to old school code
2019-01-12T23:38:23  * karlp shrugs
2019-01-12T23:38:30 < qyx> do you mean some rust-ware?
2019-01-12T23:38:32 < karlp> mucos just felt like it was stuck whhere it had been.
2019-01-12T23:38:39 < karlp> freertos at least thas more users around.
2019-01-12T23:38:56 < karlp> I just didn't like the apis at all for mucos
2019-01-12T23:40:29 < mawk> I see
2019-01-12T23:40:35 < mawk> how do you compare freertos to commercial stuff ?
2019-01-12T23:42:12 < zyp> freertos feels a bit old school to me, but fairly usable
2019-01-12T23:42:38 < karlp> ony commerciall one I coudl try was cmsis-rtx now that it's avilable
2019-01-12T23:42:45 < karlp> none of the others did evals
2019-01-12T23:43:04 < karlp> ucos was like freertos, but older, and way smaller community, so ~zero gain
2019-01-12T23:43:24 < karlp> cmsis-rtx was nicer syntax, but klunky if you weren't using keil

2019-01-13T01:21:14 < invzim> Looking at this one, https://media.digikey.com/pdf/Data%20Sheets/Omron%20PDFs/XF2M.pdf
2019-01-13T01:21:26 < invzim> "• Dual-sided contact reduces the number of parts.
2019-01-13T01:21:28 < invzim> "
2019-01-13T01:22:03 < invzim> I'll have a play with 3d models and see if the dimensions/pins adds up
2019-01-13T01:25:56 < zyp> yeah
2019-01-13T01:26:04 < zyp> that's what they mean by reducing number of parts
2019-01-13T01:26:20 < zyp> it'll work for both top-contact and bottom-contact FFC
2019-01-13T01:26:43 < zyp> yes
2019-01-13T01:26:52 < zyp> it's a common issue when dealing with FFC
2019-01-13T01:28:16 < zyp> the disadvantage is that it's easy to fuck up if the orientation is not obvious 
2019-01-13T01:28:32 < invzim> I'll make a test pcb :)
2019-01-13T01:29:03 < invzim> I really like the ssd1306 OLED screens, but the PTH versions are a PITA to assemble, and the hot-bar stuff is prob not any better - so found this:

2019-01-13T01:29:55 < karlp> what do the cables themselves cost?
2019-01-13T01:31:33 < karlp> invzim: why don't you get the connector from eastrising as well?
2019-01-13T01:32:07 < karlp> I think ffc is the way to go for some board to board stuff I've got in mind honestly.
2019-01-13T01:32:19 < karlp> current shti with edge soldered contacts is teh suck
2019-01-13T01:32:33 < invzim> karlp: want to have boards assembled by 3rd party, or at least the option to do it
2019-01-13T01:32:50 < invzim> ordered a few samples to play with
2019-01-13T01:32:59 < karlp> well, you've got to ship them parts anyway right, including the screens?
2019-01-13T01:33:10 < karlp> but sure, no need to buy vendor accessories :)
2019-01-13T01:33:37 < invzim> not sure how I'll actually physically mount the screens - think glue is the common way to do it
2019-01-13T01:33:58 < invzim> and I won't have clear pcb area dedicated for that
2019-01-13T01:34:39 < invzim> I think, things will get a little more clear once I get them physically

2019-01-13T01:47:26 < invzim> want to redesign to use fpc instead
2019-01-13T01:48:14 < invzim> or glue or something like that
2019-01-13T01:48:24 < invzim> there is a soic8 under there as well
2019-01-13T01:48:36 < invzim> not sure if it's physically feasible, but I think it may be
2019-01-13T01:49:07 < invzim> gtg, catch you fantastic guys later
2019-01-13T01:49:38 < aandrew> invzim: I have a bunch of the hotbar ones
2019-01-13T01:50:40 < aandrew> the fpc option is nice but that immediately limits your sources
2019-01-13T01:51:45 < karlp> hang on, so the lcd vendor has _different_ options for "hotbar assembly" vs fpc assemby?
2019-01-13T01:52:00 < karlp> I though you just either hotbar'd it to you board, or used a fpc connector?
2019-01-13T01:52:54 < karlp> from the pics it' sjust length of the connector?
2019-01-13T01:52:57 < aandrew> karlp: no, the hotbar ones don't have any matching connector
2019-01-13T01:54:34 < karlp> right ok, I see it now zoomed in on the pics: https://www.buydisplay.com/media/catalog/product/cache/1/image/c577d1203d4a53d9f98182eb6081b1d6/e/r/er-oled0.96-1_bottomview_2.jpg vs https://www.buydisplay.com/media/catalog/product/cache/1/image/c577d1203d4a53d9f98182eb6081b1d6/e/r/er-oled0.96-1.3_1_1.jpg
2019-01-13T01:55:26 < karlp> I guess the "hotbar" version is just fatter. you could always hotbar the "connector" veersion too, just tighter tolerances

2019-01-13T15:49:09 < jpa-> dongs: in true linux fashion, python can be helpful in so many ways! you can code your design in migen, myhdl, veriloggen or pyrtl, and then in addition to figuring out verilog problems, you can sometimes also have python problems!

2019-01-13T15:51:14 < dongs>  ???
2019-01-13T15:51:42 < jpa-> do you want that to be combinatorial, or synchronous?
2019-01-13T15:51:48 < dongs> the hell does that mean
2019-01-13T15:51:59 < dongs> i just want to execute shit when the flag is set and clock is low
2019-01-13T15:52:02 < jpa-> combinatorial = simple and gate, changes immediately when input signals change
2019-01-13T15:52:32 < jpa-> "execute shit" sounds like something more than a simple AND gate
2019-01-13T15:52:43 < dongs> no, i jsut dont know what im doing so
2019-01-13T15:52:48 < jpa-> so then you need to sync it to *one* edge, either to clock falling edge, or psync_flag rising edge
2019-01-13T15:53:37 < jpa-> you cannot tell "do this when this condition is true" because that would mean "do it all the time when the signals are in this state", instead of "do it once when the clock rises"
2019-01-13T15:54:02 < dongs> yeah so how do i tell that difference

2019-01-13T15:54:52 < jpa-> that would be something like    always @(posedge psync_flag) begin  ... do shit ... end
2019-01-13T15:55:08 < jpa-> inside that begin..end you can put   if (!clk)   if you want
2019-01-13T15:55:15 < dongs> oh what hteh fuck  already have that then
2019-01-13T15:55:22 < dongs> im just adding if (shit) inside that
2019-01-13T15:55:25 < dongs> and its beign a fucking nigger
2019-01-13T15:55:42 < dongs> oh psync_flag is a reg
2019-01-13T15:56:07 < dongs> hm wait, i dont even need that. the fuck am i doing
2019-01-13T15:56:21 < jpa-> usually you'd have everything inside   always @(posedge clk)    instead.. but then !clk makes no sense because clock would never be low if it has just had posedge
2019-01-13T15:59:10 < dongs> ok so
2019-01-13T15:59:11 < dongs> if I have
2019-01-13T15:59:20 < dongs> always posedge clk, psync
2019-01-13T15:59:26 < dongs> and then inside that ill do
2019-01-13T15:59:29 < dongs> if (psync) {
2019-01-13T15:59:33 < dongs> is that only gonna run when it goes high?
2019-01-13T15:59:44 < dongs> or all the time while its high
2019-01-13T15:59:49 < dongs> fucking garbage man
2019-01-13T15:59:56 < jpa-> um, "always @(posedge clk, psync)"  doesn't seem like it would work
2019-01-13T16:00:02 < dongs> well, you get the idea
2019-01-13T16:00:08 < jpa-> no, i don't :)
2019-01-13T16:00:09 < dongs> always @(posedge clk_in or posedge psync_in)
2019-01-13T16:00:15 < dongs> this  compiles at least
2019-01-13T16:00:16 < jpa-> no, that wouldn't work either
2019-01-13T16:00:23 < dongs> fucks sake
2019-01-13T16:00:34 < dongs> why the hell not
2019-01-13T16:00:35 < jpa-> hm, well the synthetizer might find some funny way to implement that
2019-01-13T16:00:50 < dongs> but i want to reset some stuff on psync going high
2019-01-13T16:01:12 < jpa-> but the flipflops on FPGA usually only have one clock input, so you can only trigger on one edge (+ usually a separate reset input, which is more limited in what you can do)
2019-01-13T16:01:26 < jpa-> maybe it synthetizes to use the async reset logic then
2019-01-13T16:02:38 < Thorn> dongs: always @(posedge clk) { if (psync == 1 && old_psync == 0) { ... } }
2019-01-13T16:02:43 < Thorn> you want something like that
2019-01-13T16:03:21 < Thorn> and of course old_psync <= psync; every clock cycle
2019-01-13T16:03:27 < jpa-> yeah, check psync only on clock edges if you can
2019-01-13T16:03:28 < dongs> man
2019-01-13T16:03:44 < dongs> ok
2019-01-13T16:03:45 < dongs> lets see

2019-01-13T16:04:42 < Laurenceb_123> wut
2019-01-13T16:07:05 < Thorn> what you really can't do is trigger on an async input in a sync circuit
2019-01-13T16:07:41 < jpa-> (except one async input, in case the fpga in question has async reset inputs into its flipflops)
2019-01-13T16:08:10 < jpa-> despite coding in a somewhat high-level language, one needs to think about how it will get implemented in hardware
2019-01-13T16:09:02 < dongs> https://i.imgur.com/Jto3Uid.png like, sbyte and clk are synced
2019-01-13T16:09:12 < dongs> so on sbyte going up i wanna reset some counters and shit
2019-01-13T16:09:13 < dongs> i cant delay it
2019-01-13T16:09:19 < dongs> sbyte = psync in mycode
2019-01-13T16:10:02 < jpa-> there isn't such thing as synced edges, one will always be before or after the other
2019-01-13T16:10:25 < dongs> uh so what teh shit do i do>?
2019-01-13T16:10:26 < jpa-> i think you'd want to do things on the falling edge of the CLK there
2019-01-13T16:10:34 < jpa-> then all the signals will be stable
2019-01-13T16:11:09 < jpa-> and when you see SBYTE go high and remember it was low the prior CLK edge, you can reset counters and do whatever else you should do on CLK edge

2019-01-13T16:38:28 < dongs> what is syncronizing anything

2019-01-13T16:38:43 < dongs> 125mhz clock
2019-01-13T16:39:00 < aandrew> and sys_clk?

2019-01-13T16:39:08 < dongs> 25mhz or someshit
2019-01-13T16:39:10 < dongs> i ont care about that one

2019-01-13T16:41:41 < dongs> so i dont care about what its clocked from or etc
2019-01-13T16:41:55 < aandrew> ok so you are shifting in 8bit data on a 125MHz clock and putting what you find on 8 pins?
2019-01-13T16:42:02 < dongs> yeah, serial to parallel
2019-01-13T16:42:09 < dongs> and halvingg? 1/8'ing? the clock
2019-01-13T16:42:13 < dongs> to turn it into parallel clock
2019-01-13T16:42:15 < aandrew> right
2019-01-13T16:42:16 < dongs> 1/4'ing the clock?
2019-01-13T16:42:17 < dongs> i think
2019-01-13T16:44:06 < aandrew> I think you're trying to do too much at once

2019-01-13T16:49:00 < Ecco> (This bus == ITCM bus)
2019-01-13T16:49:10 < dongs> i thought tcm = tightly coupled shit
2019-01-13T16:49:21 < Ecco> dongs: yeah, but it's also the name of a bus
2019-01-13T16:49:48 < Ecco> which the CPU uses to access said memory, _plus_ the internal Flash
2019-01-13T16:49:50 < jpa-> hmm yeah, the manual seems to contradict me
2019-01-13T16:50:04 < dongs> is there less ugly way to do i++
2019-01-13T16:50:06 < dongs> in veriblog
2019-01-13T16:50:06 < Ecco> I'm not sure though, the manual isn't very precise
2019-01-13T16:50:48 < dongs> i also have no idea between difference in <= and =
2019-01-13T16:50:53 < dongs> both compile..
2019-01-13T16:50:57 < dongs> im sure means completely different shit
2019-01-13T16:51:12 < jpa-> Ecco: AN4667 may be relevant
2019-01-13T16:51:38 < dongs> how can i simulate this shit
2019-01-13T16:51:50 < dongs> i think they removed waveform simulation in like ISE 6
2019-01-13T16:51:56 < dongs> in fact i dont see any sim shit at all
2019-01-13T16:51:58 < Ecco> Interesting, thanks
2019-01-13T16:52:01 < dongs> for 20gigs of shit installed
2019-01-13T16:52:06 < dongs> that is sure unimpressive

2019-01-13T16:52:50 < Ecco> I assume I have misconfigured the F7, but I have a hard time finding out why/ow

2019-01-13T16:54:22 < dongs> and now no warnigns
2019-01-13T16:54:25 < dongs> the fuck is the difference?
2019-01-13T16:54:31 < dongs> isnt it literally same shit

2019-01-13T16:54:52 < aandrew> not sure the difference in verilog but it could be converting to int and back when you're not doing bit

2019-01-13T16:56:01 < Ecco> well yeah, supposedly the L1 cache does its magic
2019-01-13T16:56:35 < Ecco> But even when running code from the interal flash on both MCUs, I don't see a great perf difference
2019-01-13T16:57:14 < jpa-> how are you measuring, and what kind of code?
2019-01-13T16:57:25 < Ecco> measuring with a clock :)
2019-01-13T16:57:52 < Ecco> code is a mandelbrot fractal using MicroPython
2019-01-13T16:57:56 < Ecco> so supposedly CPU-bound
2019-01-13T16:59:04 < Ecco> Things I haven't done yet : 1/ put the stack in the TCM (I don't know if it has any impact) 2/ Enable D-cache (for some reason it crashes) 3/ Enable Over-drive (not sure it's needed)
2019-01-13T16:59:34 < Ecco> but even without all this, I would have hoped for a significant performance gap between an F4 and an F7 clocked at twice the speed
2019-01-13T17:00:51 < Ecco> oh, thanks jpa- 
2019-01-13T17:00:57 < Ecco> your AN seems to  have an anwser

2019-01-13T17:01:55 < jpa-> oh, interesting
2019-01-13T17:01:59 < Ecco> he refman, they actually did mention this
2019-01-13T17:02:00 < dongs> so uh
2019-01-13T17:02:03 < dongs> how can i simulate this
2019-01-13T17:02:07 < dongs> it seems isim is installed
2019-01-13T17:02:15 < dongs> oh right. aandrew uses opensores
2019-01-13T17:02:18 < dongs> fuckin hell
2019-01-13T17:02:26 < dongs> gnu/hdl
2019-01-13T17:02:31 < dongs> how can that even be useful
2019-01-13T17:04:03 < Ecco> Extra question: the AN/RefMan say explicitely that DTCM/ITCM can be accessed at clock speed w/o any wait-states
2019-01-13T17:04:12 < Ecco> but they don't explicitely say anything for "regular" SRAM
2019-01-13T17:04:30 < Ecco> is the TCM faster than SRAM or did they just not mention it?
2019-01-13T17:05:01 < jpa-> AFAIK they are the same speed, but because the regular AHB/AXI bus is shared by many masters (DMA etc.), the CPU may sometimes have to wait
2019-01-13T17:05:10 < Ecco> oh, makes sense
2019-01-13T17:05:15 < Ecco> I see
2019-01-13T17:05:38 < Ecco> same speed, but CPU latency to TCM is guaranteed since it's the only one using it
2019-01-13T17:05:54 < jpa-> though i assume the CPU also has to wait if some other master accesses TCM through the AHB-CPU-bridge
2019-01-13T17:06:14 < Ecco> yeah, they talk about that. You can give the CPU a higher priority in that case
2019-01-13T17:06:21 < Ecco> and it only applies to DTCM anyway
2019-01-13T17:06:26 < Ecco> (ITCM is CPU-only)
2019-01-13T17:06:29 < jpa-> true
2019-01-13T17:09:03 < dongs> oh
2019-01-13T17:09:05 < dongs> theres simulation tab
2019-01-13T17:09:05 < dongs> ok
2019-01-13T17:09:18 < dongs> aandrew: the tools shouldnt matter, but how can i poke random stuff like clock/data etc
2019-01-13T17:09:23 < dongs> to have some input to the shit
2019-01-13T17:09:32 < dongs> do oi have to write a fucking verilog test bench  hting
2019-01-13T17:11:15 < aandrew> yep
2019-01-13T17:11:29 < aandrew> basically you have to create the signal you want to test against
2019-01-13T17:12:56 < mawk> that reminds me of my vhdl classes
2019-01-13T17:13:11 < mawk> nobody liked to write that testbench
2019-01-13T17:13:11 < dongs> aandrew: how? my source is basically can be any random .ts bitstream
2019-01-13T17:13:20 < dongs> cant i just read some shit from a file?
2019-01-13T17:13:31 < dongs> or fuck i donno
2019-01-13T17:13:32 < dongs> googling
2019-01-13T17:13:34 < aandrew> well that's where you figure how strict you want your code to be
2019-01-13T17:13:39 < aandrew> you can read from file of course
2019-01-13T17:13:42 < aandrew> but really you don't care for that
2019-01-13T17:13:46 < aandrew> you are just testing the shift register
2019-01-13T17:13:49 < dongs> yeah sure
2019-01-13T17:13:50 < dongs> i mean
2019-01-13T17:13:55 < dongs> in ISE6 i would just draw the fucking waveforms
2019-01-13T17:13:58 < dongs> but i think they got rid of that
2019-01-13T17:13:59 < dongs> so wat do
2019-01-13T17:14:05 < aandrew> so create a .v that generates 16 bits, with that first byte with SYNC high and the second with SYNC low
2019-01-13T17:14:18 < dongs> generates to what
2019-01-13T17:14:29 < aandrew> let me paste my .vhdl testbench for SPI so you can see what I did and adapt
2019-01-13T17:14:49 < dongs> ugh vhdl how good is that gonna do to me
2019-01-13T17:16:06 < aandrew> https://pastebin.com/iax3kEEA
2019-01-13T17:16:10 < dongs> ok lets se
2019-01-13T17:16:20 < dongs> jesus
2019-01-13T17:16:22 < aandrew> basically you're creating code that generates signals and then instantiating your module to test it
2019-01-13T17:16:23 < dongs> you lost me at like 10th line down
2019-01-13T17:16:25 < aandrew> this is a larger one
2019-01-13T17:16:35 < aandrew> becaues I created a procedure to do a spi transfer
2019-01-13T17:16:57 < aandrew> basically I'm just creating MOSI/SCK/SS and a (I think for me 50MHz) system clock
2019-01-13T17:17:03 < aandrew> then I wire that shit up to the module I'm actually writing
2019-01-13T17:17:27 < aandrew> you use a sim tool (I'm using ghdl) and it spits out waveforms, sometimes via vcd files you ahve to feed to a viewing tool
2019-01-13T17:17:53 < aandrew> in that paste, my module I'm testing is called 'uut'
2019-01-13T17:18:06 < aandrew> so in the port map I wire up the testbench signals to it to see how it responds to them
2019-01-13T17:18:29 < aandrew> then I have a clock process that just generates my system clock. do the same for sck because I'm lazy
2019-01-13T17:18:44 < aandrew> forget do_lookup, I'm just testing my register lookup there
2019-01-13T17:19:48 < aandrew> stim_proc is where I'm actually exercising things. I make sure asserting reset does what I want, I make sure that the module responds well to shitty masters, then I am just practising register reads/writes to see if it does the right thing
2019-01-13T17:20:12 < aandrew> so for yours, you would just reset, then set sync high and create a sync byte
2019-01-13T17:20:15 < aandrew> you don't have to be fancy
2019-01-13T17:20:19 < aandrew> literally something like
2019-01-13T17:20:36 < aandrew> wait for clk = '1';
2019-01-13T17:20:40 < dongs> yeah but thats vhdl. i hav enough trouble reading veriblog. anyway, checking for some wa to do this crap
2019-01-13T17:20:42 < aandrew> sync_bit <= '1'
2019-01-13T17:20:48 < aandrew> databit <= '0';
2019-01-13T17:20:52 < aandrew> wait for clk = '1';
2019-01-13T17:20:56 < aandrew> databit <= '1';
2019-01-13T17:21:00 < aandrew> wiat for clk = '1'
2019-01-13T17:21:00 < dongs> lol.. hm ok
2019-01-13T17:21:00 < aandrew> etc
2019-01-13T17:21:13 < aandrew> it gets tedious to do that which is why I created procedures to do some of that for me
2019-01-13T17:21:36 < aandrew> test benches can get real fancy, read from files, call external processes, print shit, etc. etc.
2019-01-13T17:21:56 < aandrew> all comes down to how thoroughly you want to test
2019-01-13T17:22:19 < aandrew> you can do screwy timings where the data bit is skewed in relation to the clock, etc. but I don't think you care about any of that shit
2019-01-13T17:22:40 < aandrew> you just want to see your moudle emit 0x47 blah blah blah blah
2019-01-13T17:24:40 < aandrew> you'll find development REALLY speeds up with testbenches/sim
2019-01-13T17:24:50 < dongs> i have noidea dude.
2019-01-13T17:24:58 < aandrew> I really like ghdl for that because it literally creates an executable you run and it spits out a .vcd 
2019-01-13T17:25:08 < aandrew> so you can use a makefile and shit
2019-01-13T17:27:59 < dongs> ok i added test harness thing and ise autogen'd somes hit
2019-01-13T17:28:01 < dongs> i think i get it

2019-01-13T17:41:05 < englishman> yes it's an important feature if you need it
2019-01-13T17:41:17 < dongs> hmm dout is not getting set in sim
2019-01-13T17:41:19 < englishman> also interrupts are a little more flexible iirc
2019-01-13T17:41:27 < emeb> it'll go 64MHz so it's a bit faster than F0
2019-01-13T17:42:01 < englishman> cool
2019-01-13T17:42:09 < englishman> still no hardware divide

2019-01-13T17:45:25 < dongs> why is clock so much faster than all the other shit thats timed same way
2019-01-13T17:45:50 < emeb> dongs is doing Verilog!
2019-01-13T17:46:02 < dongs> no im failing at verilog

2019-01-13T17:47:05  * emeb is coming in mid-stream
2019-01-13T17:47:08 < dongs> clock is about 10x too fast i think
2019-01-13T17:47:41 < emeb> based on the source, that waveform looks right.
2019-01-13T17:47:53 < emeb> you specified a 10ns high + 10ns low period
2019-01-13T17:47:59 < emeb> and I count 10 cycles in 200ns
2019-01-13T17:48:45 < emeb> if you want a 100ns clock cycle then you need to write "#50 clk = ~clk;"

2019-01-13T18:24:50 < dongs> https://i.imgur.com/wt40PNf.png
2019-01-13T18:24:58 < dongs> its not syncronized to that wide bit below
2019-01-13T18:25:00 < dongs> taht should be one clock pulse
2019-01-13T18:25:38 < dongs> hm maybe i shoulda used 8/16/etc for cycles
2019-01-13T18:25:45 < emeb> show the source?
2019-01-13T18:26:00 < dongs> http://bcas.tv/paste/results/k2mC5d60.html
2019-01-13T18:26:04 < dongs> i think i need #40 not 50 there
2019-01-13T18:26:32 < emeb> why are you increasing the delay every step?
2019-01-13T18:26:38 < dongs> waht delay
2019-01-13T18:26:45 < dongs> i ahve no fucking clue waht im doing
2019-01-13T18:26:47 < emeb> the value after the #
2019-01-13T18:26:56 < dongs> isnt that just "do this shit at this clock cycle?
2019-01-13T18:27:21 < emeb> the #xxx number is "wait xxx time"
2019-01-13T18:27:26 < dongs> ...
2019-01-13T18:27:51 < dongs> so to do what i want what do i do?
2019-01-13T18:27:55 < dongs> #100
2019-01-13T18:27:55 < dongs> and then
2019-01-13T18:27:59 < dongs> #10 psync_in bla
2019-01-13T18:28:05 < dongs> #10 sdat_in = blah/
2019-01-13T18:28:06 < dongs> or wat
2019-01-13T18:28:24 < emeb> yes - if you want 10ns between events then use #10 for everything
2019-01-13T18:28:55 < emeb> and if you want a 10ns clock period then you want #5 clk = ~clk;
2019-01-13T18:29:37 < dongs> im changing sdat_in every clock tick, at least that s what i watn to do
2019-01-13T18:30:13 < dongs> ok #5 did the trick there
2019-01-13T18:30:43 < dongs> https://i.imgur.com/hSx4UNB.png
2019-01-13T18:31:13 < emeb> of course now everything is on the falling edge
2019-01-13T18:31:17 < emeb> of clk
2019-01-13T18:31:24 < dongs> oh.
2019-01-13T18:31:26 < dongs> is taht wrong?
2019-01-13T18:31:31 < dongs> yeah i think thats off from waht my code shoudl be doing
2019-01-13T18:31:35 < dongs> i should do delay of 95?
2019-01-13T18:31:37 < dongs> initial
2019-01-13T18:31:51 < emeb> if you want output changing on FE that's fine
2019-01-13T18:32:09 < dongs> no, the code is doing negedge 
2019-01-13T18:32:14 < dongs> i mean, the code being tested
2019-01-13T18:32:27 < emeb> then you're good
2019-01-13T18:33:18 < dongs> ok
2019-01-13T18:33:26 < dongs> well, Dout isnt being assigned, so i fucked up somewhere i guess
2019-01-13T18:33:30 < dongs> hmm clock_out isnt working either
2019-01-13T18:33:31 < dongs> nice
2019-01-13T18:35:20 < dongs> err... post-routing sim works
2019-01-13T18:36:17 < dongs> huh
2019-01-13T18:36:19 < dongs> its completely wrong tho
2019-01-13T18:36:37 < emeb> didn't set initial values on some states?
2019-01-13T18:36:48 < emeb> would lead to propagating X
2019-01-13T18:37:05 < emeb> but post-route includes FPGA initialization to known values
2019-01-13T18:37:18 < dongs> https://i.imgur.com/Su4cdvS.png
2019-01-13T18:37:49 < dongs> dout loosk completely dongs
2019-01-13T18:37:56 < dongs> it should be 0x47
2019-01-13T18:38:02 < dongs> or 0b01000111
2019-01-13T18:38:25 < emeb> ya - just deserial of sdat_in
2019-01-13T18:38:34 < dongs> but it doesnt look that.
2019-01-13T18:38:37 < emeb> nope
2019-01-13T18:38:52 < dongs> hm also its off by one bit...
2019-01-13T18:39:38 < dongs> oh wait
2019-01-13T18:39:40 < dongs> thats my garbage code
2019-01-13T18:39:46 < emeb> source for top module?
2019-01-13T18:40:01 < dongs> http://bcas.tv/paste/results/XVtMzR37.html
2019-01-13T18:40:03 < dongs> dont laugh to hard
2019-01-13T18:40:08 < dongs> this was a days worth of wank
2019-01-13T18:41:21 < emeb> working up the curve.
2019-01-13T18:43:17 < emeb> so what you're trying to do is start a counter on rising edge of psync
2019-01-13T18:43:33 < emeb> then grab the value of sreg when the counter rolls over 8 cy cles later
2019-01-13T18:43:52 < emeb> counter and sreg are always running
2019-01-13T18:43:56 < dongs> i think so, im probly doing it wrong tho
2019-01-13T18:44:17 < dongs> thus causing one clock delay
2019-01-13T18:44:54 < emeb> since counter always runs, you'll be updating psync every time counter = 3'b000, so every 8 cycles.
2019-01-13T18:45:05 < emeb> s/psync/dout/
2019-01-13T18:45:16 < dongs> yeah
2019-01-13T18:45:19 < dongs> thats what i want, i think
2019-01-13T18:46:10 < dongs> https://i.imgur.com/MELIB60.png ok so at least CLK_OUT works correctly
2019-01-13T18:46:19 < dongs> PSYNC is correctly forwarded out to match 
2019-01-13T18:46:21 < dongs> hmm wait, fuck
2019-01-13T18:46:25 < dongs> i need to delay everything by 8bits
2019-01-13T18:46:29 < dongs> including psync_out
2019-01-13T18:46:45 < dongs> because i can't have the correct DOUT before gathering all 8 bits
2019-01-13T18:46:55 < emeb> yeah
2019-01-13T18:47:14 < dongs> tahts probly why i had psybnc_flag shit in ther bfeore hmm
2019-01-13T18:47:15 < emeb> also note that DOUT updates at beginning too. loads whatever is in sreg
2019-01-13T18:47:26 < dongs> does it?
2019-01-13T18:47:30 < dongs> because of assign?
2019-01-13T18:47:53 < emeb> anytime count = 0
2019-01-13T18:48:21 < emeb> so it sees count get reset to 0 at rising edge of psync
2019-01-13T18:48:23 < dongs> ah yeah i see it
2019-01-13T18:49:50 < emeb> and the reason your pre-route sim has X outs is that you never initialize psync_old
2019-01-13T18:49:57 < emeb> so the first if() always fails
2019-01-13T18:50:12 < emeb> because psync_old is always X
2019-01-13T18:50:22 < dongs> where do i initialize that?
2019-01-13T18:50:25 < dongs> in the test sim?
2019-01-13T18:50:26 -!- mirage335 [~mirage335@mirage335-base.soaringindustries.space] has quit [Ping timeout: 260 seconds]
2019-01-13T18:50:30 < emeb> in top
2019-01-13T18:50:39 < emeb> add an "initial" block
2019-01-13T18:50:48 < emeb> to set state of sreg and psync_old to 0
2019-01-13T18:50:52 < dongs> isnt that for sim only?
2019-01-13T18:51:01 < emeb> it's OK to use in FPGA
2019-01-13T18:51:15 < emeb> because FPGAs reset their registers at powerup
2019-01-13T18:51:25 < emeb> not OK in ASIC because no global reset

2019-01-13T18:52:46 < emeb> but if you want to be really anal retentive then you provide a global reset to your logic and clear regs when that asserts.
2019-01-13T18:52:58 < dongs> yeah i dont have that and this is jsut a quick wank test anyway
2019-01-13T18:53:03 < dongs> psync is basically reset
2019-01-13T18:53:10 < dongs> i don't care about any other shit before or after it
2019-01-13T18:54:12 < dongs> behavioural still didnt work bit i dont really carea bout that
2019-01-13T18:55:11 < emeb> whatevs
2019-01-13T18:55:15 < dongs> ok so to delay... i ahve to start a counter at psync going high
2019-01-13T18:55:22 < dongs> collect sreg
2019-01-13T18:55:29 < dongs> er counter = flag
2019-01-13T18:55:48 < dongs> on next count[] overflow, i clear flag and pulse out sbyte_out
2019-01-13T18:55:53 < dongs> set another flag
2019-01-13T18:56:07 < dongs> on next count[] poverflow, clear sbyte_out
2019-01-13T18:56:16 < dongs> clear that falg too
2019-01-13T18:56:22 < dongs> any... less idiotic way?
2019-01-13T18:56:39 < emeb> well, sounds like a lot of counters
2019-01-13T18:56:51 < emeb> but I don't know what your requirements are.
2019-01-13T18:57:01 < mawk> how many times do you cycle between different flags dongs 
2019-01-13T18:57:04 < mawk> just 2 times like this ?
2019-01-13T18:57:09 < mawk> you don't need a less idiotic way
2019-01-13T18:57:20 < dongs> ya
2019-01-13T18:57:37 < mawk> because idiotic is good for documentation
2019-01-13T18:57:43 < mawk> up to a certain extent
2019-01-13T19:00:38 < dongs> ok lets see
2019-01-13T19:01:48 < dongs> definitely cucked something up
2019-01-13T19:01:49 < dongs> damn
2019-01-13T19:02:21 < dongs> i think my count[] should be testing at like 7 not at 0
2019-01-13T19:02:25 < dongs> to dl all those things
2019-01-13T19:04:42 < dongs> emeb: if pclk_count[3:0] is it even gonna hit > 7 ever?
2019-01-13T19:05:05 < dongs> hm 4 bit counter?
2019-01-13T19:05:19 < dongs> so i guess yes it will
2019-01-13T19:13:42 < dongs> i dont think i need both count[] and pclk_count[].. tehy do same shit
2019-01-13T19:13:45 < dongs> time to try and clean this shit up
2019-01-13T19:21:34 < dongs> Net <dout[7]> does not have a driver.
2019-01-13T19:21:34 < dongs> wat
2019-01-13T19:21:37 < dongs> this is new
2019-01-13T19:22:49 < dongs> ah, count[] was a 3 bit counter not 4
2019-01-13T19:24:29 < dongs> hm emeb. why this shit in behavioral doesnt work? i already init everything in initial
2019-01-13T19:25:36 < dongs> post routed test takes fucking ages
2019-01-13T19:25:39 < dongs> to compile
2019-01-13T19:26:09 < emeb> do you initialize every reg to known value?
2019-01-13T19:26:30 < dongs> well
2019-01-13T19:26:43 < dongs> http://bcas.tv/paste/results/7IRSRw88.html
2019-01-13T19:26:57 < dongs> liek this i guess
2019-01-13T19:27:14 < emeb> maybe add all stuff inside top to waveform output.
2019-01-13T19:27:35 < dongs> i can view it
2019-01-13T19:27:37 < dongs> while stepping
2019-01-13T19:27:44 < dongs> they're all xx's

2019-01-13T19:27:47 < emeb> that's wrong
2019-01-13T19:27:49 < dongs> oh
2019-01-13T19:27:50 < dongs> yeah it is
2019-01-13T19:27:52 < dongs> 8'
2019-01-13T19:27:53 < emeb> needs to be 7'b
2019-01-13T19:27:56 < emeb> ya that
2019-01-13T19:28:19 < emeb> but that doesn't fix if counters etc not running right.

2019-01-13T19:46:45 < emeb> it's in an edge-sensitive always block and using non-blocking assignments, so there's the possibility of a conflict sending and received are both high.

2019-01-13T20:01:42 < dongs> DOUT is almost correct, just off by one bit
2019-01-13T20:02:19 < emeb> do the capture when count = 8, not 7?
2019-01-13T20:02:37 < dongs> if (count > 7) begin
2019-01-13T20:02:39 < dongs> i thought i did that
2019-01-13T20:02:47 < emeb> ah right
2019-01-13T20:03:07 < emeb> does that update at 8 and 9, 10, etc?
2019-01-13T20:03:19 < dongs> no i set it back to 0 in that if

2019-01-13T20:05:18 < dongs> and not parallel
2019-01-13T20:05:34 < emeb> yeah - that's a hurdle to get over
2019-01-13T20:05:58 < dongs> but in either case i have no idea wahts wrong :p
2019-01-13T20:07:29 < dongs> hmm sreg is one clock cycle delayed
2019-01-13T20:07:49 < emeb> get rid of that #1

2019-01-13T20:08:38 < dongs> waht teh fuck is it, is that actualyl same thing as #delay in test bench?
2019-01-13T20:08:43 < dongs> i didnt write that
2019-01-13T20:08:46 < dongs> i think i copied from somewehre
2019-01-13T20:09:02 < emeb> cargo cult!
2019-01-13T20:09:02 < dongs> is that wahts fucking it up?

2019-01-13T20:38:00 < rajkosto> whats the max switching frequency you could get a stm32 SMPS to be
2019-01-13T20:38:50 < dongs> over 9000MHz
2019-01-13T20:40:02 < englishman> gpio clock / 2
2019-01-13T20:40:23 < englishman> or rather timer clock / 2 I guess
2019-01-13T20:40:36 < englishman> but then you are stuck at 50% duty cycle only
2019-01-13T20:40:51 < englishman> so it would not be a very flexible smps
2019-01-13T20:41:12 < dongs> https://i.imgur.com/5nz7boW.png looks like my pclk_out is busted too
2019-01-13T20:41:16 < dongs> one cycle too long
2019-01-13T20:41:28 < dongs> and probly needs to be inverted but thats easy
2019-01-13T20:53:31 < rajkosto> englishman, i would think either ADC or Interrupts would be the bottlenecks
2019-01-13T20:54:35 < qyx> why
2019-01-13T20:54:55 < qyx> switching freq != control loop freq
2019-01-13T20:55:57 < rajkosto> switching freq at 1MHz would leave only 72 pwm levels possible
2019-01-13T20:56:07 < rajkosto> but control loop freq would have to be way lower
2019-01-13T20:57:01 < qyx> you could also do some kind of dithering
2019-01-13T20:57:12 < qyx> but that sounds too Laurenceb_123-ish
2019-01-13T20:59:47 < Thorn> rajkosto: look at f373, they have HRTIM

2019-01-13T21:31:44 < rajkosto> Thorn, i would rather use a fixed function SMPS chip but none of them have an "instant" EN pin
2019-01-13T21:32:46 < rajkosto> need to be able to enable and disable its output very quickly (> 1KHz), all the ones that have EN pin take some time after its gone high to start up
2019-01-13T21:35:39 < qyx> did you try smps led drivers with EN pwm dimming?
2019-01-13T21:35:51 < qyx> they need to react fast

2019-01-13T21:37:43 < jpa-> karlp: huh.. weird that they chose to map it at different offset, instead of just having a configurable remap through some register
2019-01-13T21:40:51 < rajkosto> qyx, not fast enough
2019-01-13T21:41:29 < rajkosto> ive actually had more luck feeding my pwm signal into the current sense pin via 30k resistor
2019-01-13T21:41:51 < qyx> why do you need to turn on/off so quick?
2019-01-13T21:42:00 < rajkosto> create epilepsy
2019-01-13T21:42:01 < qyx> cannot you use a power switch after the converter?
2019-01-13T21:42:12 < rajkosto> that confuses the hell out of it
2019-01-13T21:42:49 < BrainDamage> use a stable SMPS and then toggle the outpit
2019-01-13T21:43:06 < BrainDamage> you cannot fast startup a SMPS due to multiple reasons
2019-01-13T21:43:09 < rajkosto> either way i dont know how to wire it since the one i have switches the low
2019-01-13T21:43:27 < BrainDamage> for one the inductor needs to be charged, and the control loop has finite bandwith
2019-01-13T21:43:38 < BrainDamage> typically hundred Hz or so
2019-01-13T21:44:21 < rajkosto> i need more then
2019-01-13T21:44:41 < rajkosto> qyx, cant use a power switch after the converter because it confuses current sense
2019-01-13T21:45:00 < englishman> Start coding online with the Arduino Web Editor, save your sketches in the cloud, and always have the most up-to-date version of the IDE, including all the contributed libraries and support for new Arduino boards.
2019-01-13T21:45:18 < BrainDamage> rajkosto: how does it?
2019-01-13T21:45:27 < rajkosto> makes smps think it should be at 100% duty cycle
2019-01-13T21:45:42 < rajkosto> as theres no current out even though its workin it
2019-01-13T21:45:53 < BrainDamage> add a small bleeding resistor
2019-01-13T21:46:29 < rajkosto> i think the onyl way would be to have some sort of switch that keeps wasting power ?
2019-01-13T21:47:31 < rajkosto> the CS override is working best actually, with no additional components
2019-01-13T21:47:43 < jpa-> rajkosto: current out? so is this constant-current, not constant-voltage smps?
2019-01-13T21:47:48 < rajkosto> yep
2019-01-13T21:47:59 < qyx> lul
2019-01-13T21:48:07 < qyx> then simply short the output?
2019-01-13T21:48:35 < BrainDamage> ^
2019-01-13T21:49:08 < jpa-> 1kHz doesn't seem particularly fast anyway, with most SMPS operating at >100kHz
2019-01-13T21:49:11 < rajkosto> that makes it turn off and doesnt turn on until i reset it
2019-01-13T21:49:18 < rajkosto> (toggle EN pin)
2019-01-13T21:49:48 < qyx> why does it turn off?
2019-01-13T21:49:52 < rajkosto> overcurrent
2019-01-13T21:49:54 < qyx> does it detect zero output voltage?
2019-01-13T21:50:29 < jpa-> rajkosto: is it a buck or a boost regulator?
2019-01-13T21:50:51 < rajkosto> a boost regulator operating in buck mode

2019-01-13T22:04:47 < mawk> so it gets very very expensive very quickly to be negative

2019-01-13T22:05:32 < mawk> no the calculator was 10€
2019-01-13T22:05:41 < mawk> but it was the very last transaction
2019-01-13T22:05:45 < mawk> that fused the card
2019-01-13T22:05:50 < mawk> yes Steffanx 
2019-01-13T22:05:56 < mawk> because I'm not supposed to be that low
2019-01-13T22:06:05 < mawk> I'm virtually even lower because I had money that wasn't mine on that account
2019-01-13T22:06:20 < mawk> but I'm pretty sure I didn't spent all that much, I'll review the transactions tomorrow to spot if there was a fraud

2019-01-13T23:25:30 < zyp> I'm gonna run 3x32A to a sub panel there, hence the thick conduit, but I don't have the parts for that yet
2019-01-13T23:26:06 < zyp> so for now I just pulled some old cable I had through the conduit and hooked it to one of the existing circuit breakers
2019-01-13T23:27:02 < zyp> house has dedicated circuits for both laundry machine and dryer, since I have a combined unit I'm only using one of them, so I'm using the other one for the charger now
2019-01-13T23:27:35 < zyp> not entirely legal to do it like that, but eh, it'll do fine as a temporary thing :p

2019-01-13T23:28:48 < zyp> there shouldn't be any real safety risk involved here
2019-01-13T23:29:31 < Steffanx> why wouldnt it be legal zyp?
2019-01-13T23:30:05 < Steffanx> Is that flexible conduit a permanent solution ( i never like that when its not covered) 
2019-01-13T23:30:43 < zyp> in addition to not strictly being allowed to do this myself, the only violations I've got is that the conduit is not fastened satisfactory and I don't have a DC RCD on the charging circuit
2019-01-13T23:32:03 < zyp> I'm planning to put the conduit inside a … hmm, I forgot the word

2019-01-14T00:51:50 < zyp> Steffanx, well, dutch and norwegian seems to halfway be mutually intelligible
2019-01-14T01:18:53 < mawk> I never did category theory and this statement is intelligible to me Cracki 
2019-01-14T01:18:57 < mawk> everything's fine
2019-01-14T01:19:39 < mawk> :(
2019-01-14T01:20:16 < mawk> a mondad is a set of endofunctors with an associative law
2019-01-14T01:20:19 < mawk> and a neutral element
2019-01-14T01:20:41 < mawk> the endo- in endofunctor means it goes to the same set it's coming from
2019-01-14T01:20:50 < mawk> it relates to functionnal programming
2019-01-14T01:20:59 < mawk> and program proving and stuff

2019-01-14T01:22:33 < mawk> well it's a fundamental structure yeah
2019-01-14T01:22:40 < mawk> like a plain monoid is in group theory
2019-01-14T01:22:55 < mawk> you add more properties and you get from monoid to group, to ring, to field, etc
2019-01-14T01:23:42 -!- ski7777 [~quassel@ip5b437013.dynamic.kabel-deutschland.de] has joined ##stm32
2019-01-14T01:23:53 < mawk> the description of a field in itself doesn't help for doing stuff, but you have a rich theory on fields that can be applied to anything that can be viewed as a field
2019-01-14T01:24:47 < mawk> yeah they're historical names I guess
2019-01-14T01:24:53 < zyp> so what's the understandable description of a monad?
2019-01-14T01:24:56 < mawk> that come from the initial usage they've been introduced for
2019-01-14T01:24:58 < zyp> because now I'm wondering what it is
2019-01-14T01:25:06 < mawk> I don't think you can understand that without some background zyp 
2019-01-14T01:25:12 < mawk> but the thing to understand is what a functor is
2019-01-14T01:25:18 < mawk> once you get it a monoid is pretty simple
2019-01-14T01:25:28 < mawk> well category theory is nicknamed "abstract nonsense"
2019-01-14T01:25:32 < mawk> among mathematicians
2019-01-14T01:25:37 < zyp> a functor is a function-object, no?
2019-01-14T01:27:08 < zyp> I'd describe a functor as a object that both has state and is callable, but I'm not sure that's accurate
2019-01-14T01:28:14 < mawk> it's something like a meta-function that can act on objects like a regular function but also wrap other functions
2019-01-14T01:28:20 < karlp> zyp: heh, we hhave those tiger stroop too.
2019-01-14T01:28:49 < zyp> hmm, seems like haskell uses the term differently
2019-01-14T01:28:52 < mawk> your functor can act on objects of a category, but can also act on morphisms of that category (to another category, or to the same category)
2019-01-14T01:28:54 < zyp> https://en.wikipedia.org/wiki/Functor_(disambiguation)
2019-01-14T01:28:56 < mawk> while preserving nice properties
2019-01-14T01:30:41 < zyp> karlp, nice, didn't expect anybody to recognize the shop
2019-01-14T01:30:58 < karlp> I dind't buy any though, thye looked kinda so so
2019-01-14T01:31:09 < zyp> same
2019-01-14T01:31:23 < mawk> you could say it's a higher-order function zyp 
2019-01-14T01:31:26 < mawk> for summary
2019-01-14T01:31:38 < mawk> a function (functor) that acts on functions (morphisms)
2019-01-14T01:32:25 < PaulFertser> zyp: C++ guy explains https://bartoszmilewski.com/2015/05/11/using-monads-in-c-to-solve-constraints-1-the-list-monad/

2019-01-14T01:36:24 < specing> monads monads monads   *haskelling intensifies*
2019-01-14T01:38:27 < PaulFertser> "If you know what to look for you’ll find monads everywhere."
2019-01-14T01:40:00 < mawk> yeah I don't like this approach Cracki 
2019-01-14T01:41:47 < mawk> but it's really higher-order
2019-01-14T01:41:55 < mawk> if it returns a new function, that is
2019-01-14T01:42:17 < mawk> if it's int (int (*fp)()); in C++ it's not higher-order
2019-01-14T01:42:44 < mawk> the term is borrowed from other parts of maths
2019-01-14T01:42:51 < mawk> for instance the theory of tensors
2019-01-14T01:42:56 < mawk> of linear forms
2019-01-14T01:43:07 < mawk> you have functions that take functions that return a function that take a function ...
2019-01-14T01:43:17 < mawk> lol
2019-01-14T01:43:29 < mawk> not really majored because I was doing drugs all of the time
2019-01-14T01:43:33 < mawk> but it was my favorite coursez
2019-01-14T01:43:57 < mawk> yeah
2019-01-14T01:44:21 < mawk> the intitulate was "mathematics, physics and engineering sciences"
2019-01-14T01:44:27 < mawk> then the second year was just "mathematics, physics"
2019-01-14T01:44:32 < mawk> but more maths than physics
2019-01-14T01:45:36 < mawk> yeah
2019-01-14T01:45:39 < mawk> I don't like this approach
2019-01-14T01:45:43 < mawk> mathematics is an art on its own
2019-01-14T01:45:54 < mawk> it should be treated with infinite respect
2019-01-14T01:45:55 < mawk> yeah
2019-01-14T01:46:12 < mawk> it's not really constructed, I think it's rather discovered
2019-01-14T01:46:17 < mawk> mathematics are self-consistent
2019-01-14T01:46:27 < mawk> an alien at the other edge of the universe would discover the same maths as us
2019-01-14T01:46:41 < mawk> well maths usually lead the real world 200 years or so
2019-01-14T01:46:54 < mawk> maths discovered some centuries ago are useful today in physics
2019-01-14T01:47:24 < mawk> you can't publish if it's not consistent
2019-01-14T01:47:27 < mawk> you'll be laughed at
2019-01-14T01:47:30 < mawk> unlike psychology
2019-01-14T01:47:45 < mawk> or philosophy or whatever
2019-01-14T01:47:54 < mawk> where you can always construct stuff and call that a theory

2019-01-14T17:13:37 < aandrew> your HDL waits for the falling edge and then looks at the other signals to see their state, right?

2019-01-14T17:14:32 < dongs> how do i delay a signal by 8 clocks?
2019-01-14T17:14:40 < aandrew> #1 problem is that you're thinking in software
2019-01-14T17:14:45 < aandrew> it's not software, it's hardware, you've got to think in hardware
2019-01-14T17:14:51 < aandrew> anyway 
2019-01-14T17:15:01 < aandrew> if you imagine a 7474 or wahtever D flip flop
2019-01-14T17:15:07 < marble_visions> is it me or C can't really do sizeof(my_struct.my_field) ?
2019-01-14T17:15:08 < aandrew> when the clock changes, it samples D and puts it on Q
2019-01-14T17:15:22 < dongs> marble_visions: it most absoultely does
2019-01-14T17:15:51 < aandrew> marble_visions: C does that without issue
2019-01-14T17:16:22 < marble_visions> indeed, there was something else going on, thanks :)
2019-01-14T17:16:28 < aandrew> dongs: if you look at the datasheet for any D flip flop it will have something called setup and hold time requirements
2019-01-14T17:16:45 < aandrew> basically whatever is on D must be stable 'x' ns before the clock change, and must remain stable for 'x' ns after the clock change
2019-01-14T17:17:03 < aandrew> otherwise it cannot guarantee that that the signal that was sampled will be stored correctly
2019-01-14T17:17:04 < dongs> uh , i dont think i'm even at the point of giving about about that aandrew 
2019-01-14T17:17:08 < jadew> dongs, to delay the signal for 8 clock cycles you need a shift register
2019-01-14T17:17:13 < dongs> my shit is basically failing in behavior sim
2019-01-14T17:17:16 < karlp> I get how making the test drive on positive when the target samples on negative "works"
2019-01-14T17:17:24 < karlp> but is that really the standard way of writing the tests?
2019-01-14T17:17:28 < aandrew> yes
2019-01-14T17:17:33 < aandrew> because that is how the actual hardware does it too
2019-01-14T17:17:35 < karlp> can't you just write them to say, "plus x% clock" ?
2019-01-14T17:17:39 < aandrew> well yes
2019-01-14T17:17:43 < karlp> how does one test ddr stuff?
2019-01-14T17:17:50 < aandrew> the spec will say sample on falling edge and s/h requirements are whatever ns
2019-01-14T17:17:59 < aandrew> but really what the driving ahrdware will almost always do is drive on rising
2019-01-14T17:17:59 < jadew> karlp, you need a DDR model
2019-01-14T17:18:03 < aandrew> it guarantees maximum s/h 
2019-01-14T17:18:05 < karlp> I would have thought, naiively, that you'd setup your tests to run some x time in front of each edge.
2019-01-14T17:18:11 < aandrew> karlp: ddr is a different beast
2019-01-14T17:18:18 < aandrew> and will usually just have s/h requirements
2019-01-14T17:18:28 < jadew> ah, that's what you mean, yeah, you can time delay
2019-01-14T17:18:29 < aandrew> karlp: depends on the system for sure
2019-01-14T17:18:43 < aandrew> but most hardware drives on opposite sample edge because it's trivial to implement in hardware
2019-01-14T17:18:43 < karlp> it just sounds like "tests run on one edge, target samples on other edge" is a convenient work around rather htan specifying your setuyp times better
2019-01-14T17:18:53 < karlp> ok then.
2019-01-14T17:18:57 < dongs> jadew: and waht do i set as output, 7th bit of the register?
2019-01-14T17:19:05 < jadew> dongs, yeah
2019-01-14T17:19:18 < dongs> lets fucking see
2019-01-14T17:19:19 < aandrew> dongs: np, just let me know what you're trying to do. you're almost there but this is important t understand why the shit's failing
2019-01-14T17:19:37 < dongs> fucking yes
2019-01-14T17:19:41 < dongs> instantly fixed the psync shit.
2019-01-14T17:20:18 < aandrew> well until you run into metastable problems 
2019-01-14T17:20:38 < aandrew> if your system is clocked from the incoming clock there will be none, but if not you'll have it work most of the time but fail occasionally and it'll drive you mad

2019-01-14T17:21:44 < marble_visions> ugh: https://stackoverflow.com/questions/3553296/sizeof-single-struct-member-in-c
2019-01-14T17:22:02 < dongs> uhhhhh
2019-01-14T17:22:06 < dongs> what teh FUCK are you trying to do
2019-01-14T17:22:32 < aandrew> he's trying to declare a struct member which is an arry to be the sizeof another struct member
2019-01-14T17:22:35 < dongs> whatever itis, it sounds really bad
2019-01-14T17:22:38 < dongs> yeah i know
2019-01-14T17:22:39 < aandrew> stop trying to be cute and just use #define
2019-01-14T17:22:42 < dongs> but thats fucking awful
2019-01-14T17:23:15 < jadew> marble_visions, you can use a union if you need char * access to the data
2019-01-14T17:23:20 < marble_visions> i'm only trying to get the size of an element of a struct
2019-01-14T17:23:30 < marble_visions> and it's not an array, it's an uint16_t
2019-01-14T17:23:39 < marble_visions> i wanted to use sizeof to make it more flexible
2019-01-14T17:23:42 < aandrew> marble_visions: sizeof(struct.foo) does it 
2019-01-14T17:23:55 < aandrew> if you want to *use* sizeof(struct.foo) as the size of an array, stop trying to be cute
2019-01-14T17:24:00 < jadew> marble_visions, why not just define a property of that type?
2019-01-14T17:24:15 < jadew> union { MyType x; char * xp; }
2019-01-14T17:24:40 < marble_visions> aandrew: it's not an array
2019-01-14T17:24:44 < marble_visions> it's an uint16_t
2019-01-14T17:24:54 < karlp> so share your concrete problem then
2019-01-14T17:24:55 < aandrew> marble_visions: stop trying to give us shit one little bit at a time
2019-01-14T17:25:00 < aandrew> tell us, clearly, what it is you're trying to do
2019-01-14T17:25:10 < aandrew> you've said you want to get the size of an array member, we told you how
2019-01-14T17:25:14 < aandrew> now you're saying something else
2019-01-14T17:26:00 < marble_visions> aandrew: i haven't said anything about arrays?
2019-01-14T17:26:26 < aandrew> marble_visions: again, please state clearly and concisely what it is you are trying to do
2019-01-14T17:26:32 < dongs> yeah dont link to blindleadingtheblind.com
2019-01-14T17:26:36 < dongs> actually explain wtf youre trying to do
2019-01-14T17:26:49 < dongs> cuz whatever the fuck that nigger there is doing is dumb
2019-01-14T17:27:11 < qyx> you are not being nice
2019-01-14T17:27:44 < dongs> https://i.imgur.com/I36Wxjm.png ok so PSYNC_OUT solved
2019-01-14T17:27:51 < marble_visions> i want to get the size of an uint16_t element from a struct, in case uint16_t later changes to uint32_t or uint8_t 
2019-01-14T17:27:55 < dongs> now i need to figure out why my DOUT is 2 bits offset 
2019-01-14T17:28:23 < dongs> im grabbing serial data from sdat_in using a shift register, and I want it on d-out once the register is full
2019-01-14T17:28:26 < jadew> dongs, looks like ISim
2019-01-14T17:28:31 < dongs> it is
2019-01-14T17:28:33 < jadew> you didn't turn on Xilinx? :P
2019-01-14T17:28:36 < marble_visions> or you want to know why i want to know the size of an uint16_t?
2019-01-14T17:28:55 < dongs> marble_visions: so where's the problem?
2019-01-14T17:29:03 < dongs> struct nigger {
2019-01-14T17:29:03 < dongs> uint16_t blogger;
2019-01-14T17:29:03 < dongs> }
2019-01-14T17:29:03 < dongs> struct nigger fagggot;
2019-01-14T17:29:03 < dongs> sizeof(faggot.blogger) = ?
2019-01-14T17:29:27 < jadew> 5
2019-01-14T17:29:29 < Thorn> does freertos completely clobber main stack when the scheduler starts? i.e. Foo foo; vTaskStartScheduler(); <-- is foo still alive and can it be references from within tasks?
2019-01-14T17:29:38 < dongs> 2, but thats not the point
2019-01-14T17:29:44 < aandrew> marble_visions: and sizeof(struct.member) works, does it not?
2019-01-14T17:29:52 < dongs> of course it works
2019-01-14T17:29:58 < marble_visions> yep, just tested it out, issue is that struct is typedef'd
2019-01-14T17:30:09 < aandrew> marble_visions: code please
2019-01-14T17:30:46 < marble_visions> later, got to go now
2019-01-14T17:30:52 < jadew> lol
2019-01-14T17:30:55 < marble_visions> anyway thanks all
2019-01-14T17:30:59 < aandrew> heh
2019-01-14T17:31:00 < jadew> must be a secret strcut
2019-01-14T17:31:04 < jadew> *struct
2019-01-14T17:31:14 < aandrew> jadew: no then he'd use & :-)
2019-01-14T17:31:17 < aandrew> er ->
2019-01-14T17:31:31 < marble_visions> yes, i'll be linking to an NDA soon, i'd like all of you to sign please :D

2019-01-14T17:32:44 < aandrew> Thorn: hm, I best check my code, I think I do keep some shit in main()'s stack in some code
2019-01-14T17:33:20 < dongs> http://bcas.tv/paste/results/vQPCy052.html
2019-01-14T17:33:38 < aandrew> I always enjoy dongs' code snippets
2019-01-14T17:34:20 < marble_visions> dongs: you're cheating
2019-01-14T17:34:25 < dongs> how so
2019-01-14T17:34:34 < Thorn> dongs needs to work on readability. type names should be capitalized
2019-01-14T17:34:36 < marble_visions> i can also do it via a var of the type 
2019-01-14T17:34:41 < dongs> ...
2019-01-14T17:35:20 < aandrew> Thorn: i'll cut your tongue out if you ever suggest capitalizing anything in C ever again
2019-01-14T17:35:20 < marble_visions> issue is i can't plug in the type name directly
2019-01-14T17:35:31 < dongs> yeah no capital variables in C plz
2019-01-14T17:35:36 < dongs> straight off to the cat oven you go
2019-01-14T17:36:09 < qyx> vDongsDelete
2019-01-14T17:36:10 < qyx> also
2019-01-14T17:36:18 < qyx> Thorn: how would you use variables from the main()?
2019-01-14T17:36:18 < dongs> < jadew> you didn't turn on Xilinx? :P < jadew  waT?
2019-01-14T17:36:25 < Thorn> aandrew: right now I'm code like struct Leds Leds; Leds->Toggle();
2019-01-14T17:36:36 < dongs> please name another fpga package that at least attempts to integrate sim into workflow
2019-01-14T17:36:37 < jadew> dongs, the recent outrage about Xilinx being assholes :P
2019-01-14T17:36:42 < dongs> oh yeah, they're assholes for suer
2019-01-14T17:36:46 < aandrew> qyx: you don't; but you may define something that you pass along to tasks defined
2019-01-14T17:36:48 < dongs> but i found XP vm with thier warez isntalled os im ok
2019-01-14T17:36:58 < dongs> i dont care what platform this ends up being on
2019-01-14T17:37:02 < dongs> HDL is HDL anywhere
2019-01-14T17:37:04 < Thorn> qyx: pass pointer to it into a task as the pvParameters
2019-01-14T17:37:06 < dongs> i just want it to work
2019-01-14T17:37:12 < qyx> oh
2019-01-14T17:37:35 < aandrew> dongs: is your FPGA going to be doing anything other than taking serial data in and outputting to an 8 bit bus?
2019-01-14T17:37:41 < dongs> yeah, thats it
2019-01-14T17:37:51 < aandrew> I bet you're using an Artix 7 for that task. :-)
2019-01-14T17:37:55 < dongs> totally
2019-01-14T17:38:01 < dongs> the $20k version
2019-01-14T17:38:10 < dongs> devboard on teh desk makes more heat than my aircon in heater mode
2019-01-14T17:38:18 < aandrew> heh
2019-01-14T17:38:22 < c10ud> sup, anyone hit from ampire 10.1" lvds screens being out of production?
2019-01-14T17:38:30 < dongs> > lvds
2019-01-14T17:38:33 < dongs> yeah there's y our problem
2019-01-14T17:38:48 < dongs> you can get 10.1" 2 lane eDP screens tho with standar 30 pin ipex
2019-01-14T17:39:01 < c10ud> yeah, glass mfr out of business lol
2019-01-14T17:39:17 < c10ud> old crap using this stuff
2019-01-14T17:40:55 < aandrew> what's the FreeRTOS way of passing data to/from interrupt handlers to standard tasks?
2019-01-14T17:41:19 < dongs> don't they have the usual rtos primitives?
2019-01-14T17:41:26 < dongs> queues/semaphores/mutex/etc
2019-01-14T17:41:41 < aandrew> that's what I'm thinking. just use a queue or smh
2019-01-14T17:41:44 < aandrew> smth
2019-01-14T17:43:45 < dongs> ok so jadew, if i have 8 bit serial shift register collecting data, when do I know its time to output it?
2019-01-14T17:43:56 < dongs> i tried keeping 3 bit counter and checking on 0
2019-01-14T17:44:03 < dongs> that results in 2 clock cycles off for conversion
2019-01-14T17:44:10 < dongs> i tried keepign 4 bit counter and checking when its == 8
2019-01-14T17:44:13 < dongs> thats off by one
2019-01-14T17:44:16 < jadew> dongs, you don't do it with the counter
2019-01-14T17:44:19 < dongs> then?
2019-01-14T17:44:24 < jadew> on each clock cycle you shift the bits
2019-01-14T17:44:45 < dongs> but when they're all shifted, i need to copy it to DOUT
2019-01-14T17:44:46 < jadew> you shift and set the 0 bit to the current value
2019-01-14T17:44:53 < dongs> yeah, shifting works
2019-01-14T17:44:53 < jadew> just make a wire
2019-01-14T17:45:01 < dongs> it can't change while its shifting tho
2019-01-14T17:45:07 < jadew> assign DOUT = sr[7]
2019-01-14T17:45:20 < dongs> nono. DOUT is 8bits. parallel output
2019-01-14T17:45:26 < jadew> ah
2019-01-14T17:45:28 < dongs> so i collect 8 bits 
2019-01-14T17:45:33 < dongs> then i want to assign that to output.
2019-01-14T17:45:46 < jadew> hold on... you said you wanted to delay a signal
2019-01-14T17:45:52 < dongs> oh thats done
2019-01-14T17:45:53 < jadew> the shift register was for a single signal, not for 8
2019-01-14T17:45:56 < dongs> that works fine
2019-01-14T17:46:01 < dongs> < dongs> https://i.imgur.com/I36Wxjm.png ok so PSYNC_OUT solved
2019-01-14T17:46:09 < jadew> so what's the problem now?
2019-01-14T17:46:16 < dongs> see sdat_in?
2019-01-14T17:46:19 < dongs> and DOUT
2019-01-14T17:46:27 < dongs> i want 01000111 in sdat_in
2019-01-14T17:46:30 < dongs> in DOUT
2019-01-14T17:46:33 < dongs> once its done shifting it in
2019-01-14T17:46:44 < dongs> but its missing 2 bits in my current version
2019-01-14T17:47:17 < jadew> ah, I see what you mean
2019-01-14T17:47:21 < dongs> psync_in going high is a reset signal so i clear all stuff and initialize shift reigster and shift in first stuff
2019-01-14T17:47:27 < jadew> you want to accumulate them via sdat_in
2019-01-14T17:47:27 < aandrew> I'd just do it with a counter but that's just me
2019-01-14T17:47:28 < dongs> or at least thats waht my code is written to do
2019-01-14T17:47:28 < dongs> but its not
2019-01-14T17:47:34 < dongs> yes, im using counter but its failing.
2019-01-14T17:47:37 < jadew> and then keep them steady for 8 cycles in DOUT
2019-01-14T17:47:40 < dongs> i dont know when to actually shift out
2019-01-14T17:47:43 < aandrew> set to 7 on psync_in rising edge, when zero, output
2019-01-14T17:47:43 < dongs> jadew: yes
2019-01-14T17:47:46 < jadew> you need another register for DOUT
2019-01-14T17:47:54 < dongs> jadew: i have one
2019-01-14T17:48:03 < dongs> aandrew: there's lots more bytes of data after psync
2019-01-14T17:48:07 < aandrew> so what
2019-01-14T17:48:08 < jadew> you shift them in each clock cycle and when you get to 8 you copy them to the DOUT register
2019-01-14T17:48:11 < aandrew> oh
2019-01-14T17:48:12 < aandrew> I see
2019-01-14T17:48:22 < aandrew> yeah ok but hten you just keep decremebting becuase after 0 you'll underflow
2019-01-14T17:48:25 < aandrew> and start at 7 again
2019-01-14T17:48:25 < dongs> jadew: yeah i made that. lemme put that code back
2019-01-14T17:48:33 < aandrew> fuck it why don't I just write the shit in vhdl and show you
2019-01-14T17:48:52 < dongs> no
2019-01-14T17:48:54 < dongs> cuz vhdl is unreadable
2019-01-14T17:48:58 < dongs> and i wanna figure this out

2019-01-14T17:52:00 < dongs> hmm now its completely broke
2019-01-14T17:52:16 < dongs> o yeah i forgot to clear coutner.
2019-01-14T17:52:37 < jadew> you can step over stuff too
2019-01-14T17:52:42 < dongs> oh i do.
2019-01-14T17:52:42 < emeb> verilogging like a fiend.
2019-01-14T17:52:42 < jadew> like you would debug a program
2019-01-14T17:52:45 < dongs> it doesnt help
2019-01-14T17:52:52 < dongs> shit changes but id ont know why
2019-01-14T17:52:57 < jadew> heh
2019-01-14T17:53:05 < dongs> ok back to ysterdays problem
2019-01-14T17:53:33 < dongs> https://i.imgur.com/GMCVHsR.png = http://bcas.tv/paste/results/ofAKPG16.html
2019-01-14T17:53:44 < dongs> so everythign works as i want except DOUT is one bit late
2019-01-14T17:53:49 < dongs> or early rather
2019-01-14T17:53:53 < dongs> input is 01000111
2019-01-14T17:54:02 < jadew> hmm
2019-01-14T17:54:07 < dongs> and dout is 00100011
2019-01-14T17:54:09 < jadew> is that shift register OK?
2019-01-14T17:54:22 < jadew> should it be sreg[7:1], sdat_in
2019-01-14T17:54:29 < jadew> shouldn't
2019-01-14T17:54:30 < jadew> ?
2019-01-14T17:54:37 < emeb> nope
2019-01-14T17:54:41 < dongs> psync is same wway and it works
2019-01-14T17:54:51 < jadew> ok, haven't done verilog in a while
2019-01-14T17:57:02 < jadew> oh, right, it's correct
2019-01-14T17:58:08 < dongs> at 100ns, psync goes high
2019-01-14T17:58:14 < dongs> but count is already 1
2019-01-14T17:58:55 < aandrew> your approach is problematic
2019-01-14T17:59:01 < dongs> no doubt
2019-01-14T17:59:02 < aandrew> I'd not write it this way at all
2019-01-14T17:59:09 < dongs> im writing it in C
2019-01-14T17:59:12 < dongs> not in hdl
2019-01-14T17:59:49 < aandrew> you know the parable of the old woman at the doctor?
2019-01-14T18:00:12 < dongs> is it another romanian proverb shit
2019-01-14T18:00:19 < aandrew> not that I'm aware of
2019-01-14T18:00:36 < aandrew> "doctor, doctor, you've got to help me, it hurts when I tug on my ear!"
2019-01-14T18:00:42 < aandrew> "don't tug on your ear."
2019-01-14T18:01:19 < dongs> hmm i think my clock / 8 division is dumb too
2019-01-14T18:01:28 < dongs> i bet i could do this with another counter/shiftreg
2019-01-14T18:01:35 < dongs> and output its like 3rd bit or something
2019-01-14T18:01:43 < aandrew> problem #1: creating a clock from logic
2019-01-14T18:01:48 < dongs> oh fuck off i know that
2019-01-14T18:01:57 < aandrew> you should be running on a system clock and outputting a 'data valid" pulse
2019-01-14T18:01:58 < dongs> im not gonna figure out how to use DCM or whatever teh fuck
2019-01-14T18:02:05 < dongs> yes, thats not how this is gonna work
2019-01-14T18:02:07 < aandrew> but you want to do it this way
2019-01-14T18:02:07 < specing> dongs: why don't you go to #fpga? they could help you better
2019-01-14T18:02:12 < dongs> most likely i'll end up sticking this on the cheapest cpld
2019-01-14T18:02:15 < aandrew> no, they'll tell him all this same stuff
2019-01-14T18:02:24 < aandrew> or at least I will, I'm there. :)
2019-01-14T18:02:35 < specing> aandrew: yes but it'll actually be ontopic there
2019-01-14T18:02:37 < aandrew> you can do it this way, it's jsut... not riht
2019-01-14T18:02:51 < aandrew> this is ontopic here, since there is no other talk going on
2019-01-14T18:02:53 < dongs> ignoring clocking logic im open to suggestions on fixing shit
2019-01-14T18:03:10 < aandrew> dongs: well doing it right *is* the suggestion on fixing shit
2019-01-14T18:03:46 < aandrew> I mean you can use the incoming tsclk to drive the shift reg and create logic to create a 1/8 clock on ouptut which is high for 4 bits after the whole thing is shifted in
2019-01-14T18:03:58 < Thorn> specing: are you sure he's not banned there
2019-01-14T18:04:05 < specing> dongs: why are you doing verilog and not VHDL?
2019-01-14T18:04:12 < emeb> rofl
2019-01-14T18:04:23 < emeb> let's muddy the waters with a language war!

2019-01-14T18:04:35 < specing> Thorn: I'm not
2019-01-14T18:04:44 < specing> muddy?
2019-01-14T18:04:49 < specing> VHDL is vastly superior
2019-01-14T18:04:53 < dongs> specing: because vhdl is utterly unreadable, even worse than python & co
2019-01-14T18:04:55 < emeb> here we go...
2019-01-14T18:05:05  * qyx grabs popcorn
2019-01-14T18:05:09 < karlp> it's also completely irrelevant to the question at hand.
2019-01-14T18:05:13 < dongs> yes also that
2019-01-14T18:05:17 < karlp> shit in another language is still shit
2019-01-14T18:05:17 < specing> VHDL unreadable? Thats rich from someone writing verilog

2019-01-14T18:12:08 < zyp> vhdl has ancient level verbosity, like pascal
2019-01-14T18:12:09 < dongs> https://i.imgur.com/C8JeQPS.png = http://bcas.tv/paste/results/n973wQ53.html cleaned up /8 clock as well
2019-01-14T18:12:23 < zyp> verilog is a bit less verbose
2019-01-14T18:14:42 < karlp> can you actually use vhdl with things like yosys/icestorm etc? or onyl with the vendor tools?
2019-01-14T18:15:18 < zyp> is vhdl support that uncommon?
2019-01-14T18:15:35 < zyp> I had the impression they were fairly evenly matched
2019-01-14T18:15:52 < zyp> hence why there's an argument at all and no clear winner
2019-01-14T18:16:36 < karlp> I think it's ~same when you use hte vendor tools yes, but wasn't sure that was the same in yosys land
2019-01-14T18:18:07 < zyp> well, yosys is verilog specificly, so naturally you'd need an equivalent alternative that does vhdl instead
2019-01-14T18:18:35 < dongs> hmm
2019-01-14T18:18:36 < karlp> yeah, but I don't know what that is...
2019-01-14T18:18:41 < dongs> so i donno what im doing wrong here
2019-01-14T18:19:35 < dongs> does orrder of shit matter
2019-01-14T18:19:43 < dongs> like i shift in stuff after checking psync_in and other crap
2019-01-14T18:20:04 < aandrew> lots of people prefer verilog because it's less wordy and "feels" more like programming
2019-01-14T18:20:23 < zyp> aandrew, yeah, that's my main argument
2019-01-14T18:20:32 < aandrew> the latter is precisely why I don't like it, but also my vhdl preference is largely due to it being so much more suited toward writing logic
2019-01-14T18:20:49 < aandrew> delta cycles FTW
2019-01-14T18:20:51 < zyp> not that I really care all that much

2019-01-14T18:21:03 < aandrew> I find my mind trying to do sw dev in verilog all the time
2019-01-14T18:22:08 < zyp> last I toyed around with an fpga I used migen
2019-01-14T18:22:16 < Thorn> not only yosys but free sim tools (no vhdl match for icarus verilog afaik)
2019-01-14T18:22:23 < zyp> seemed a lot more useful than dicking around with HDL overall
2019-01-14T18:22:32 < dongs> yeah im not gonna change my shit to python for a fucking serial in.paralel out shift register, zyp
2019-01-14T18:22:51 < zyp> dongs, I know how much you love python :)

2019-01-14T18:24:04 < emeb> I've been coding verilog for longer than a lot of folks here have been alive. I've been using VHDL for about 10yrs. Both are fine for the stuff I do.
2019-01-14T18:24:48 < dongs> https://i.imgur.com/P2q7Lz2.png so i step this shit
2019-01-14T18:24:53 < emeb> VHDL is better a catching stupid errors during synthesis, but that only saves you a little time. Verilog gets the point across with less typing.
2019-01-14T18:25:04 < dongs> at 100ns my testbench sets psync, sdat_in is 1
2019-01-14T18:25:09 < dongs> and its supposed to reset counter to 0
2019-01-14T18:25:13 < dongs> but counter is already 1 at that point
2019-01-14T18:26:50 < dongs> if i move count++ after count = 8 compare shit completely breaks and i dont know why
2019-01-14T18:28:37 < dongs> http://bcas.tv/paste/results/NvFrSt94.html line 96 vs 110
2019-01-14T18:28:38 < dongs> why?
2019-01-14T18:28:42 < dongs> the fuck is the difference
2019-01-14T18:29:39 < emeb> order makes a difference when you have multiple assignments
2019-01-14T18:30:05 < dongs> whats 'assignment' in my code?
2019-01-14T18:30:06 < dongs> <= shit?
2019-01-14T18:30:07 < emeb> when you do it at 96 then it can be overridden by 102
2019-01-14T18:30:15 < emeb> No - that's correct.
2019-01-14T18:30:26 < emeb> always use non-blocking inside a clocked process
2019-01-14T18:30:32 < emeb> yes
2019-01-14T18:30:43 < dongs> is  this <= vs =  thing
2019-01-14T18:30:47 < dongs> i donno the difference either way
2019-01-14T18:30:54 < dongs> i doubt thats my issue either
2019-01-14T18:31:04 < emeb> you assign clock in 4 different places
2019-01-14T18:31:11 < emeb> some of them are valid at the same time
2019-01-14T18:31:18 < dongs> count you men?
2019-01-14T18:31:19 < dongs> mean
2019-01-14T18:31:23 < emeb> yes
2019-01-14T18:31:45 < dongs> i only see 2
2019-01-14T18:31:49 < emeb> 90, 96/110, 102
2019-01-14T18:32:17 < emeb> "=" is blocking. "<=" is non-blocking
2019-01-14T18:33:08 < emeb> blocking means that the simulator queues that result in the order of execution
2019-01-14T18:33:14 < emeb> so it acts like C code.
2019-01-14T18:33:30 < emeb> non-blocking means that all the results are queued at the same time step
2019-01-14T18:35:15 < emeb> It definitely makes a difference in how the synthesis tool approaches the task.
2019-01-14T18:35:57 < emeb> think of it as series vs parallel
2019-01-14T18:36:36 < emeb> a sequence of blocking assignments would be designed as one gate feeds another gate, feeds another.
2019-01-14T18:37:14 < dongs> F  UUUUUUUUUUUUUUUUUUUUUUCK KKKKKKKKKK
2019-01-14T18:38:28 < dongs> holy shit i think i fixed it
2019-01-14T18:38:36 < emeb> conga-rats
2019-01-14T18:38:41 < emeb> what'd you change?
2019-01-14T18:39:17 < dongs> https://i.imgur.com/aHJA8QK.png condition for the count == 8 thing http://bcas.tv/paste/results/SAibjX18.html
2019-01-14T18:40:35 < emeb> just moved the count inc up to the top?
2019-01-14T18:40:52 < emeb> because it was overriding the reset
2019-01-14T18:41:03 < dongs> no
2019-01-14T18:41:11 < dongs> if (count == 7) begin
2019-01-14T18:41:13 < dongs> this was == 8
2019-01-14T18:41:18 < dongs> it was getting an extra shift in
2019-01-14T18:41:19 < dongs> or someshit
2019-01-14T18:41:21 < emeb> ah
2019-01-14T18:41:30 < dongs> i think before i fixed clkdiv and psync delay
2019-01-14T18:41:37 < dongs> i was using that also to invert / delay clocks and shit
2019-01-14T18:41:41 < dongs> and it broke a lot of shit back then
2019-01-14T18:45:02 < dongs> wait fucking what
2019-01-14T18:45:18 < dongs> ah nvm wrong bits in my testbench
2019-01-14T18:45:32 < emeb> count reg can now be just 3 bits
2019-01-14T18:45:44 < emeb> since you always reset it before it gets to 8
2019-01-14T18:45:45 < dongs> yes, right
2019-01-14T18:47:10 < aandrew> heh this is why VHDL is much nicer for logic. it's a lot harder to make these mistakes

2019-01-14T18:48:40 < paul_99> Hi, just been working with a BluNRG-2 QFN32 and read in the errata...
2019-01-14T18:48:44 < paul_99> " During debug connection via (SWD) port, if a specific bit pattern is sent/ received to/from the SWDIO pin, the chip could not answer anymore subsequent SWD requests, thus breaking the connection. The bit pattern represented as 32 bit word is 0x39E6xxxx."
2019-01-14T18:49:01 < paul_99> workaround:none
2019-01-14T18:49:06 < paul_99> thats like 1 in 65535 chance
2019-01-14T18:49:13 < paul_99> how are they still shipping this product
2019-01-14T18:49:30 < paul_99> well your bitstream is effectively random data
2019-01-14T18:49:37 < aandrew> why would anyone be sending random data on SWD during reset/power up
2019-01-14T18:49:38 < karlp> no, your tools can control that 
2019-01-14T18:49:40 < paul_99> the compiler will produce what it produces
2019-01-14T18:49:49 < karlp> yes, but it doesn't have to be written over swd as is.
2019-01-14T18:49:59 < karlp> witness the ldrd errata on cortex-m.
2019-01-14T18:50:10 < karlp> compilers simply choose not to create those patterns now.
2019-01-14T18:50:27 < paul_99> so program the flash with breaks if that is detected
2019-01-14T18:50:34 < karlp> indeed.
2019-01-14T18:50:41 < aandrew> Cracki: ok fine, but if your tools are putting weird shit on the line that's a problem with the tool
2019-01-14T18:50:44 < karlp> ie, there's workaroudnsd, but nothing you can do on the part itself.
2019-01-14T18:50:50 < aandrew> I agree that this is a bug but it's so minor it's inconsequential

2019-01-14T18:54:42 < Thorn> is "BluNRG" actual part number?

2019-01-14T18:55:51 < dongs> what is it, RS232 to bluetooth?
2019-01-14T18:56:07 < paul_99> there is a new firmware update in this custom ST-LINK utility
2019-01-14T18:56:15 < paul_99> but its been a while so it could be a generic update
2019-01-14T18:56:30 < dongs> Thorn: and yeah
2019-01-14T18:56:33 < dongs> if you look at datasheet
2019-01-14T18:56:37 < dongs> 'ordering infromation' table
2019-01-14T18:56:46 < dongs> page 161
2019-01-14T18:56:48 < paul_99> so the splitting of the these word writes that is done (presumably). That must be in the ST-Link Utility firmware right ?
2019-01-14T18:57:05 < paul_99> if its only in this custom ST-Link Utility build then the problem will still exist when programming with other tools
2019-01-14T18:57:46 < paul_99> no really any more information on it than that errata note

2019-01-14T19:05:53 < dongs> it didnt work for me last time tho
2019-01-14T19:06:03 < dongs> ++'d shit would just remain at 111 or wahtever

2019-01-14T20:15:28 < jadew> heh
2019-01-14T20:16:12 < jadew> the most intense scene was when the nazgul stabbed the empty beds
2019-01-14T20:16:22 < jadew> should have covered his eyes for that
2019-01-14T20:16:26 < jadew> the other killings were ok

2019-01-14T20:18:05 < antto> i watched IT when i was 8 or less
2019-01-14T20:18:05 < jadew> I'm sure he'd want that, he seemed to enjoy it a lot

2019-01-14T20:44:21 < Thorn> The largest parabolic dish antennas in the world are the Five-hundred-meter Aperture Spherical radio Telescope in southwest China, and the Arecibo radio telescope in Arecibo, Puerto Rico, US, which both have effective apertures of about 300 meters. The gain of these dishes at 3 GHz is roughly 90 million, or 80 dBi.
2019-01-14T20:45:03 < jadew> that's a good antenna
2019-01-14T20:45:35 < jpa-> too bad that you need to rotate a whole planet for the rough aiming
2019-01-14T20:47:47 < jadew> learned from the last thunderfoot video that the new horizon probe (the one that did the pluto photo-shoot has only a 12 W transmitter)
2019-01-14T20:49:37 < jadew> and it takes 5 hours for the signal to reach us

2019-01-14T20:52:25 < jadew> can only imagine now weak the signal is
2019-01-14T20:52:56 < specing> the signal rate is half a kilobit per second or something ridiculous like that
2019-01-14T20:53:09 < jadew> yeah, 600 bps
2019-01-14T20:53:24 < jadew> @ 4 GHz
2019-01-14T20:53:34 < specing> isn't new horizons nuclear powered?
2019-01-14T20:53:40 < jadew> it is
2019-01-14T20:53:57 < specing> so what prevented them from mounting a 100+W transmitter on it?
2019-01-14T20:54:08 < jadew> don't know...
2019-01-14T20:54:19 < jadew> apparently it has a 200W power source or something
2019-01-14T20:54:53 < jadew> maybe they just wanted to keep it interesting
2019-01-14T20:55:12 < jadew> they wanted funding for a bigger dish
2019-01-14T20:55:18 < specing> where do the other190Wgo?
2019-01-14T20:55:32 < jadew> good question
2019-01-14T20:56:51 < BrainDamage> 100W transmitter would mean no budget for the instruments
2019-01-14T20:57:13 < BrainDamage> you still need to operate the sensors, the radar, the computer, etc
2019-01-14T20:57:29 < jadew> well, you could turn them off during data transmissin
2019-01-14T20:57:33 < jadew> *transmission
2019-01-14T20:57:45 < jadew> but I guess they figured all they need is 12 W
2019-01-14T20:57:46 < BrainDamage> it's transmitting continously
2019-01-14T20:57:59 < BrainDamage> at 600bps, to transmit a pic you need many hours/days
2019-01-14T20:58:24 < BrainDamage> and yes, you need the slow rate to lower the SNR requirements
2019-01-14T20:58:44 < BrainDamage> also the power at the antenna, before the antenna gain is 10log10(12W/1mW)+35−10log10((4pi·(5h·c)/(c/4GHz))^2) = 223dBm
2019-01-14T20:58:49 < jpa-> 250W is the heat power of the RTG, you get perhaps something like 50W electricity out of it
2019-01-14T20:59:02 < jadew> ah ha
2019-01-14T20:59:07 < jadew> that explains it then
2019-01-14T20:59:10 < BrainDamage> -223dBm
2019-01-14T20:59:40 < BrainDamage> I've assumed a 35dB dish on the probe
2019-01-14T20:59:52 < BrainDamage> which should be ok given the size and freq
2019-01-14T21:00:11 < BrainDamage> it might differ by say, +-5dB, but won't change the order of magnitude of my calc
2019-01-14T21:00:17 < BrainDamage> so -220dBm or so
2019-01-14T21:00:33 < jadew> not sure if it's 4 or 8 GHz
2019-01-14T21:00:47 < jadew> I've read a paper where they said they planned something and went with something else
2019-01-14T21:00:51 < jadew> but it's one of the two
2019-01-14T21:01:33 < BrainDamage> with 8GHz it's -229, not a huge difference
2019-01-14T21:01:45 < jadew> I didn't know you could even listen to signals that low
2019-01-14T21:02:10 < jadew> so a 50 dBi antenna would bring it to what... -180?
2019-01-14T21:02:12 -!- catphish [~catphish@unaffiliated/catphish] has joined ##stm32
2019-01-14T21:02:18 < jadew> yeah... I guess that's doable
2019-01-14T21:02:36 < BrainDamage> -180dBm may or may not be doable
2019-01-14T21:02:50 < BrainDamage> you need to compare to the noise spectral density
2019-01-14T21:02:58 < BrainDamage> integrated over the band
2019-01-14T21:03:05 < BrainDamage> that's where having slow speed helps
2019-01-14T21:03:42 < jpa-> hmm, not sure now if that 200 watts is the thermal power or the electric power, different sources say different things
2019-01-14T21:05:09 < jpa-> i guess electrical power after all, http://pluto.jhuapl.edu/Mission/Spacecraft/Systems-and-Components.php
2019-01-14T21:05:49 < BrainDamage> assuming your LNA is cooled by LN2, and bits/baud is 1, the thermal noise spectral power is 4boltzmann·77K·600Hz 10log10(4boltzmann·77K·600Hz/1mW)=-146dBm
2019-01-14T21:06:57 < BrainDamage> so your receiver system's gain, which includes both antenna gain and any eventual code gain by spread spectrum tecniques to at least -146dBm to have SNR=1
2019-01-14T21:07:09 < BrainDamage> which is considered the treshold for detection
2019-01-14T21:08:15 < BrainDamage> so your antenna gain needs to be ~80dB to work
2019-01-14T21:09:03 < BrainDamage> less if it has spread spectrum codes
2019-01-14T21:10:24 < jadew> wouldn't it be possible to use a lock in amplifier to get even better sensitivity?
2019-01-14T21:10:44 < BrainDamage> a radio IS a lock in amplifier
2019-01-14T21:11:07 < BrainDamage> compare the two, literally the same structure
2019-01-14T21:11:25 < jadew> ah... thought that's what they'd be used for
2019-01-14T21:11:58 < BrainDamage> also the numbers I cited are merely due to physical processes
2019-01-14T21:12:06 < BrainDamage> no amount of electronics can better them
2019-01-14T21:12:15 < Laurenceb_123> New Horizons?
2019-01-14T21:12:27 < BrainDamage> you can get away with less thermal noise with colder LNAs
2019-01-14T21:12:29 < Laurenceb_123> hmm I should actually launch muh rockoon

2019-01-14T21:24:45 < BrainDamage> what advantage do you have with sw gps?

2019-01-14T21:27:12 < BrainDamage> so you integrate your IMU during gps shutdown?
2019-01-14T21:27:18 < BrainDamage> to save power?
2019-01-14T21:27:32 < BrainDamage> and faster lock reacquisition
2019-01-14T21:27:33 < Laurenceb_123> one idea, yeah
2019-01-14T21:28:12 < Laurenceb_123> or power on and grab a few ms of data then process using fft based acquisition
2019-01-14T21:28:24 < Laurenceb_123> for lock once an hour type applications
2019-01-14T21:31:10 < Laurenceb_123> the core tracking part seems doable in thumb2, but then there is all the other service type stuff, and also supposedly CW blockers are required
2019-01-14T21:33:28 < qyx> I still have some SE4110L
2019-01-14T21:33:32 < qyx> I am waiting for your codez
2019-01-14T21:34:17 < Laurenceb_123> I only got as far as writing the core processing loops
2019-01-14T21:34:44 < Laurenceb_123> nibble based iirc
2019-01-14T21:35:00 < qyx> yeah you mentioned it
2019-01-14T21:35:28 < Laurenceb_123> all the other stuff is still a major headache
2019-01-14T21:35:58 < Laurenceb_123> I managed to get as far as working fixes in matlab with <3.5m error, but theres tons of stuff that has to work
2019-01-14T21:36:16 < Laurenceb_123> all the ephemeris processing and stuff, I just copypastered the libraries
2019-01-14T21:36:28 < Laurenceb_123> its v big job
2019-01-14T21:37:01 < Laurenceb_123> I guess there is Piksi, thats using stm32
2019-01-14T21:39:10 < jpa-> i'd want to experiment with GPS direction finding by putting two antennas + 2x SE4110L feeding into one FPGA or STM32, and using the time difference between antennas to find orientation; but yeah, pretty much coding to do
2019-01-14T21:39:57 < Laurenceb_123> that part is v easy if you once have the rest of it running
2019-01-14T21:41:28 < jpa-> yeah, it's the rest that is the "lot of coding" part :)

2019-01-14T21:44:20 < malinus> jpa-: you need RTK to do that. The normal GPS accuracy is way too shitty to do it. Unless you have like 20m between the antennas.
2019-01-14T21:45:56 < jpa-> malinus: yeah, of course it would use RTK (or rather, just the satellite phases directly), that's kind of the point of doing it in software instead of two separate GPS receivers
2019-01-14T21:46:48 < Laurenceb_123> actually ublox does support some useful stuff...
2019-01-14T21:46:53 < malinus> jpa-: how small a distance between the antennas do you figure you can get away with?
2019-01-14T21:47:03 < Laurenceb_123> pseudoranges and phase output over ubx on some receivers
2019-01-14T21:47:36 < malinus> with be nice with a cortex-a so you could run rtklib
2019-01-14T21:47:38 < Laurenceb_123> malinus: depends how good pointing accuracy you need and over what bandwidth
2019-01-14T21:47:44 < jpa-> malinus: i have no idea really, it will be a tradeoff between angle accuracy vs. averaging time vs. antenna distance
2019-01-14T21:48:00 < Laurenceb_123> phase wobble is usually <5 degrees with a good signal
2019-01-14T21:48:17 < Laurenceb_123> over say 20hz bandwidth
2019-01-14T21:48:56 < jpa-> also geometric dilution of precision will matter, if all the satellites you see are overhead there is not much direction finding you can do
2019-01-14T21:48:58 < Laurenceb_123> so you could use a mems gyro to get down to <1degree heading accuracy with a 35cm or some antenna spacing perhaps
2019-01-14T21:49:19 < Laurenceb_123> problem is you get signal leaking off your chassis and all sort of weird nonlinearities in the rf

2019-01-14T21:51:59 < jpa-> it's annoying how difficult it is to get accurate heading using any method; magnetometers are so sensitive to surroundings, and gyros drift too fast

2019-01-14T21:53:10 < Laurenceb_123> I can reliably get <1degree absolute heading offset from my calibrated imu
2019-01-14T21:53:15 < Laurenceb_123>  ... sitting in a field
2019-01-14T21:53:17 < mawk> because of the physics exam mainly, if it were only for the maths it'd be fine
2019-01-14T21:53:42 < Cracki> Laurenceb_123, in a field because elsewhere... earth magnetic field is disturbed or what?
2019-01-14T21:53:58 < Laurenceb_123> but it's interesting that even in steel framed buildings the heading is almost always <15degrees off
2019-01-14T21:54:03 < Laurenceb_123> Cracki: building steel
2019-01-14T21:54:09 < Cracki> yeh that fucks with things

2019-01-14T21:54:20 < mawk> you can't use the imu everywhere
2019-01-14T21:54:22 < Laurenceb_123> like down to 25% field strength
2019-01-14T21:54:31 < mawk> you usually fuse multiple sources

2019-01-14T21:56:37 < aandrew> so with FMC set up as 1 bank of 16 bit wide PSRAM, I should be able to have the stm32 start a DMA transfer to internal SRAM and have my FPGA manage the actual transfer by manipulating the WAIT# signal

2019-01-14T22:38:27 < Cracki> single mother. every time.
2019-01-14T22:38:33 < cnt> that is called a javascripting language which is installed in your hardware. not in your software 
2019-01-14T22:38:56 < Cracki> can haz pls
2019-01-14T22:39:18 < Laurenceb_123> cnt: javascript is a heating system
2019-01-14T22:39:26 < cnt> lol
2019-01-14T22:39:31 < Laurenceb_123> it heats ur house as you try to load a webpage
2019-01-14T22:39:56 < cnt> so flash is like the afterburner?
2019-01-14T22:40:17 < Laurenceb_123> flash actually works
2019-01-14T22:40:26 < Laurenceb_123> unironically replace javascript with flash
2019-01-14T22:40:38 < Cracki> flash uses ecmascript anyway
2019-01-14T22:40:50 < Cracki> the only diff is they are shit at making it perform
2019-01-14T22:42:08 < Laurenceb_123> kek wut
2019-01-14T22:42:20 < Laurenceb_123> how come flash actually runs with sane cpu useage
2019-01-14T22:43:15 < Cracki> it doesn't?
2019-01-14T22:43:28 < Cracki> perhaps because they designed it to use 100% in 2005
2019-01-14T22:44:09 < Cracki> they put more thought into how animations should work (fixed frame rate) while random js kiddies just run their js full tilt
2019-01-14T22:44:58 < Laurenceb_123> yeah flash seems well designed
2019-01-14T22:45:12 < Laurenceb_123> javascript just copypastas yuuuge libraries
2019-01-14T22:45:35 < Cracki> ah that, simply don't do it :P
2019-01-14T22:49:57 < zyp> then again, flash was actually designed
2019-01-14T22:50:36 < zyp> javascript has a ton of competing implementations, flash has one
2019-01-14T22:50:39 < Laurenceb_123> yeah
2019-01-14T22:51:14 < Steffanx> Did they design the security flaws in as well?
2019-01-14T22:51:20 < zyp> probably
2019-01-14T22:51:44 < Steffanx> I dont miss flash and hardly have an issue with javascript.
2019-01-14T22:52:09 < zyp> same
2019-01-14T22:52:41 < Cracki> js has beedn standardized for a long while
2019-01-14T22:52:45 < Cracki> as ecmascript
2019-01-14T22:53:10 < Cracki> and everyone tends to stick to some standard... just consider, js only has floats
2019-01-14T22:53:16 < Cracki> so anything beyond 53 bits is fucked
2019-01-14T22:53:34 < Cracki> someone could get the idea to introduce big nums, or at least integer types
2019-01-14T22:53:45 < Cracki> but that would fuck up too much of the ecosystem because then people would rely on that
2019-01-14T22:53:59 < zyp> there's still a lot of variation on which parts of the javascript standard are supported in the various implementations
2019-01-14T22:54:33 < Cracki> you probably mean DOM stuff and all that
2019-01-14T22:54:41 < Cracki> the language itself isn't all that complicated
2019-01-14T22:54:58 < Cracki> it's like with versions of C and C++
2019-01-14T22:59:00 < mawk> the new cubemx is so lame
2019-01-14T22:59:05 < mawk> and they even have regressions
2019-01-14T22:59:26 < mawk> the interface not registering when you modify peripherals and you have to restart, duplicated lines in the makefile like in the good old times
2019-01-14T23:00:54 < cnt> no good news
2019-01-14T23:01:01 < cnt> is there a better cortex m platform?
2019-01-14T23:01:15 < mawk> platform ?
2019-01-14T23:01:16 < cnt> seriously
2019-01-14T23:01:22 < cnt> as in 
2019-01-14T23:01:28 < cnt> a better cortex m
2019-01-14T23:01:28 < mawk> cubemx is just one part
2019-01-14T23:01:30 < mawk> ah$
2019-01-14T23:02:00 < cnt> i hear people ranting and raving, so i guess maybe there's a better cortex m with happy libraries and tools
2019-01-14T23:02:16 < mawk> stm32 is cool
2019-01-14T23:02:23 < mawk> it's just they have to devote more money to that cube thing
2019-01-14T23:02:35 < mawk> but it'd quite useful without the bugs
2019-01-14T23:02:45 < Cracki> well, people bitch about inconsistent peripherals across stm32 series, so I guess some other company must make cortex m with more consistent periphs?
2019-01-14T23:03:12 < mawk> yeah speaking of that on the disco I tried today it wants a 48 MHz clock for usb or something, but precisely 48 MHz
2019-01-14T23:03:19 < mawk> so you have to make a special multiplier and divider in the PLL
2019-01-14T23:03:30 < mawk> but when you do that you can't put the other clocks to full speed, including the cortex clock
2019-01-14T23:03:40 < mawk> so either you have USB either you have a full speed clock
2019-01-14T23:03:57 < mawk> I tried the auto clock resolver from cubemx but it tried for 20s then didn't converge
2019-01-14T23:04:21 < zyp> mawk, which part?
2019-01-14T23:04:39 < mawk> stm32f429I

2019-01-14T23:05:10 < mawk> yeah
2019-01-14T23:05:28 < zyp> yeah, that's not gonna work, IIRC you're limited to 168
2019-01-14T23:05:32 < mawk> using the 8 MHz HSE of the stlink through the PLL
2019-01-14T23:05:41 < mawk> no you can go 180 MHz, if you drop the 48 MHz clock
2019-01-14T23:05:43 < mawk> and drop USB then
2019-01-14T23:05:48 < zyp> that's what I meant
2019-01-14T23:05:50 < mawk> ah
2019-01-14T23:05:51 < mawk> yeah
2019-01-14T23:05:57 < mawk> is it deliberate design ?
2019-01-14T23:06:22 < mawk> and they advertise USB everywhere in the whitepapers and stuff, so they know USB will be activated

2019-01-14T23:07:07 < Cracki> wait, how is the 48 mhz usb clock related to system clock? factor 3.5 should be doable by some PLL
2019-01-14T23:07:22 < mawk> when you do that the PLL output clock for the other clocks is too high Cracki 
2019-01-14T23:07:26 < mawk> so it can't be done
2019-01-14T23:07:29 < Cracki> uh
2019-01-14T23:07:50 < zyp> Cracki, it's a common PLL with several dividers
2019-01-14T23:07:55 < Cracki> ic
2019-01-14T23:08:04 < mawk> one divider before, one multiplier before, then two dividers
2019-01-14T23:08:06 < zyp> so the PLL output needs to be a multiple of 48
2019-01-14T23:08:09 < mawk> one for the 48MHz, one for the other clocks
2019-01-14T23:08:18 < Cracki> integer dividers only?
2019-01-14T23:08:20 < mawk> yes
2019-01-14T23:08:31 < zyp> for those speeds, the P divider will always be /2, so you're limited to sysclk steps of 24 MHz
2019-01-14T23:08:31 < mawk> divide by 2 4 8 iirc
2019-01-14T23:08:39 < mawk> then multiplier is whatever reasonable integer
2019-01-14T23:08:42 < zyp> so next step up is 192 MHz, and that's above rating
2019-01-14T23:09:01 < Cracki> so... what's the solution, giving usb its own crystal?
2019-01-14T23:09:11 < zyp> no, the solution is running at 168 MHz

2019-01-14T23:17:06 < zyp> but I'm doing ethernet on TI hercules for work, it's also mandatory DMA
2019-01-14T23:17:06 < mawk> maybe with exotic solutions
2019-01-14T23:17:17 < mawk> specing: stm32h743zi
2019-01-14T23:17:39 < zyp> anything can run linux, but there's not much of a point when you don't have a MMU
2019-01-14T23:17:41 < mawk> well linux with 1MiB ram will be complicated no ?
2019-01-14T23:17:47 < mawk> it doesn't have a mmu ?
2019-01-14T23:17:56 < mawk> I thought I saw mmu stuff in the core docs
2019-01-14T23:18:11 < zyp> cortex-m doesn't have a MMU, that's kinda the distinguishing factor between cortex-m and cortex-a
2019-01-14T23:18:14 < mawk> ah
2019-01-14T23:18:28 < mawk> it's not the same as MPU then ?
2019-01-14T23:18:30 < mawk> memory protection unit
2019-01-14T23:18:31 < zyp> no
2019-01-14T23:18:34 < mawk> ah
2019-01-14T23:18:44 < mawk> lame
2019-01-14T23:18:54 < zyp> MPU lets you set access rules for memory regions, but it doesn't virtualize memory
2019-01-14T23:19:04 < Laurenceb_123> not lame
2019-01-14T23:19:07 < zyp> a typical MMU got pagetables and stuff
2019-01-14T23:19:13 < Laurenceb_123> who needs MMU shit on embedded
2019-01-14T23:19:20 < mawk> so MPU is like segmented memory on x86 ?
2019-01-14T23:19:45 < zyp> no, segmented memory is still virtual memory, just less flexible than paging
2019-01-14T23:20:08 < zyp> cortex-m doesn't do virtual memory at all

2019-01-14T23:50:50 < mitrax> does RDP (read protection) level1 have any implication on the running code besides disabling read/erase/program from the debugger? flash can be manipulated the same way as with level 0 right? i'm wondering if it can have some side effect i haven't considered

2019-01-15T00:00:39 < Cracki> some slide set on the L4 says rdp affects the debug interface only, but other protection modes might do more
2019-01-15T00:01:03 < Cracki> PcROP protects flash even from cpu reads

2019-01-15T11:43:10 < marble_visions> seems like c++11 has what i'm looking for, but i'm not willing to switch to c++ just because of that https://en.wikipedia.org/wiki/Sizeof#Object_members
2019-01-15T11:43:19 < marble_visions> dongs: fyi ^
2019-01-15T11:44:38 < Haohmaru> c++ ftw
2019-01-15T11:45:00 < marble_visions> i'm just wondering why isn't this supported for fully defined types in c.. seems like something the compiler should know and be able to compute
2019-01-15T11:45:34 < Haohmaru> cuz the compiler acts dumb in C mode?
2019-01-15T11:46:38 < marble_visions> no idea, i think the issue is that there isn't syntax defined for accessing struct members. you can access members of a variable of type struct, but not struct members
2019-01-15T11:47:12 < Haohmaru> i can access errythang.. in C++
2019-01-15T11:47:31 < c10ud> because packing and alignment probably
2019-01-15T11:48:06 < c10ud> if types are known then why sizeof() on struct members
2019-01-15T11:48:10 < qyx> ok, so you wanted to get sizeof(struct struct_type.member)
2019-01-15T11:48:17 < qyx> not sizeof(struct_variable.member)
2019-01-15T11:48:18 -!- karlp1 is now known as karlp
2019-01-15T11:49:28 < dongs> hm
2019-01-15T11:49:38 < dongs> apparently i need some speshul pin to output 125mhz clock out of spartan6
2019-01-15T11:49:48 < dongs> i jsut wanna scope it
2019-01-15T11:50:26 < zyp> marble_visions, I haven't been following earlier conversation, but I believe the typical C pattern is something like this: sizeof((struct struct_type*)0->member)
2019-01-15T11:51:13 < dongs> zyp, yeah
2019-01-15T11:51:16 < dongs> thats what he didnt wanna do
2019-01-15T11:52:04 < zyp> cruft like that is what you get when you insist on sticking to C :p
2019-01-15T11:52:06 < marble_visions> seems like i must do it like this
2019-01-15T11:52:10 < dongs> http://bcas.tv/paste/results/V1Mz0w14.html
2019-01-15T11:52:45 < dongs> like, english plz
2019-01-15T11:54:02 < marble_visions> qyx: https://pastebin.com/6cxyzPfw neither line 13 nor line 14 compile
2019-01-15T11:54:19 < marble_visions> i was entertaining c++ if only for namespace support
2019-01-15T11:54:30 < dongs> righyfully so
2019-01-15T11:54:34 < cnt> https://i.imgur.com/AR2gcx8.jpg
2019-01-15T11:57:07 < marble_visions> c10ud: the idea was to have more flexible code, and be able to change struct member types
2019-01-15T11:57:55 < zyp> marble_visions, so what stops you from doing C++ really? nobody is forcing you to write object oriented code, you can pick the features you like and write fairly plain C otherwise
2019-01-15T11:57:57 < marble_visions> but i'll be going with the null pointer dereference quirk
2019-01-15T11:58:08 < marble_visions> zyp: indeed
2019-01-15T11:58:20 < dongs> just the fact that C++ takes way longer to compile
2019-01-15T11:58:21 < dongs> than C
2019-01-15T11:58:25 < c10ud> marble_visions, well that really depends on how you're going to design your code, but you can treat structs as a whole
2019-01-15T11:58:29 < marble_visions> lol @ dongs
2019-01-15T11:58:45 < c10ud> if you change a function member type your other code that's using it most likely will have to be modified as well
2019-01-15T11:59:15 < marble_visions> c10ud: right
2019-01-15T12:04:39 < zyp> dongs, I don't think that's the case
2019-01-15T12:05:30 < dongs> hmm
2019-01-15T12:05:42 < dongs> i need to do 2 clocks in my design for simulation and i cant figure out how
2019-01-15T12:05:55 < dongs> always begin #blah clk1 #blah clk2 isnt working
2019-01-15T12:06:00 < dongs> neither do multiple always blocks
2019-01-15T12:06:08 < dongs> 		#1 clk_in = ~clk_in;
2019-01-15T12:07:42 < specing> dongs: but it was well worth it to have turing complete templates!

2019-01-15T12:43:50 < dongs> thorn, its true, but keil compile >>>>>>>>>>>>>>>>>>> gcc in quality
2019-01-15T12:43:55 < dongs> so im willing to deal with the speed
2019-01-15T12:44:49 < Thorn> if you're using gcc 4.x before the big backend overhaul then maybe but there is now gcc 7 or even 8
2019-01-15T12:45:22 < marble_visions> dongs: about that, remember the serialization/deserialization thing 2 weeks back? that keil generates revs instead of shifts and gcc doesnt? gcc does as well, when you compile with -O2/-Og
2019-01-15T12:46:21 < marble_visions> forgot what the case was, but it was interesting that gcc seemed to not know about rev
2019-01-15T12:46:40 < marble_visions> turns out it does with optimizations enabled

2019-01-15T15:17:52 < aandrew> eg the lattice shit all works as expecte din sim because their libs are in there

2019-01-15T15:22:04 < dongs> i was told by fpgapro that lattice are kinda garbage
2019-01-15T15:22:35 < aandrew> depends on what you're after
2019-01-15T15:22:50 < aandrew> for 99% of FPGA uses lattice is cheap and low pin count and gets enough done
2019-01-15T15:23:06 < aandrew> then the rest (high speed, transcievers, etc.) is a slugfest between intel and xilinx
2019-01-15T15:23:52 < karlp> it seems a lot like, "if you know what you need, you know, if you don't, the cheapest is perfectly suitable"
2019-01-15T15:23:53 < aandrew> I'm partial to altera/intel because xilinx seems to be all about instantiating specific blocks rather than inferring them, where intel/altera is more about "describe it correctly and we will correctly infer it" which seems a better general approach
2019-01-15T15:24:00 < aandrew> karlp: 100% exactly
2019-01-15T15:24:19 < aandrew> dongs: you may (MAY!) be able to get away with those stupid greenpak devices for your specific need (serial to parallel)
2019-01-15T15:24:31 < aandrew> but they're very tiny (logic space) so even that may not fit
2019-01-15T15:24:33 < karlp> wot you callin stupid mate?!
2019-01-15T15:24:43 < dongs> ya but i wanna have shit i can actually purchase in the future
2019-01-15T15:24:49 < dongs> anyway, mach XO2 is fine for this i think
2019-01-15T15:24:51 < dongs> there's a 32qfn

2019-01-15T15:24:57 < karlp> greenpack got bought up by dialog, so not going away anytime soon.
2019-01-15T15:25:01 < dongs> i could probly even do a little reclocking fifo on that thing
2019-01-15T15:25:06 < dongs> oh yea?
2019-01-15T15:25:20 < karlp> iirc, yosys even targets prev gen of greenpak
2019-01-15T15:25:42 < karlp> I've got training emails from dialog post acquisition, so I don't think they just bought the people and are killing it either
2019-01-15T15:26:37 < aandrew> yeah but x03 is cheaper I bet
2019-01-15T15:26:55 < dongs> why would xo3 be cheaper than xo2
2019-01-15T15:27:01 < aandrew> karlp: I never found a good use for them, and being such a tiny little device (in the sense of programmable logic) it makes me worried about having them around in future
2019-01-15T15:27:20 < karlp> me either :)
2019-01-15T15:27:29 < aandrew> karlp: interesting I'll have to check them out again
2019-01-15T15:27:30 < karlp> but then, I've never needed an fpga either....
2019-01-15T15:27:35 < aandrew> dongs: it was when I was designing this prototype
2019-01-15T15:27:42 < aandrew> but ultimately I went ice40lp
2019-01-15T15:27:53 < karlp> or, I've always used hte hammers I have, perhaps...
2019-01-15T15:27:55 < dongs> XO3 only comes in retard packages
2019-01-15T15:27:56 < aandrew> which was a mistake I think becuase the toolset is completely different

2019-01-15T15:30:34 < dongs> yep
2019-01-15T15:31:09 < aandrew> oh maybe that si why I went ice40

2019-01-15T15:31:34 < aandrew> I used xo2 to convert 4 lane MIPI to 32-bit parallel for fx3

2019-01-15T15:33:00 < Sadale> \o/ I managed to use 5 IO pins to control 16 LEDs + 9 buttons + a slider switch.
2019-01-15T15:33:32 < aandrew> that stupid digitizer board I made I placed, reflowed, reballed, placed, reflowed a 178 ball 0.8mm bga and a 256 ball 1.0mm bga before I realized my soldering is pro and the problem was elsewhere
2019-01-15T15:33:33 < karlp> ecp2 comes in tqfp, but only 144 lead :)

2019-01-15T15:34:40 < karlp> 55x55mm whee

2019-01-15T15:36:59 < karlp> jus picked the biggest not the newest
2019-01-15T15:37:58 < dongs> i wonder whats the best practice for calling in/out port names
2019-01-15T15:38:06 < dongs> to not confuse shit
2019-01-15T15:38:16 < aandrew> zipcpu dude actually recently did a thing on that
2019-01-15T15:38:16 < dongs> aandrew: wat do you do
2019-01-15T15:38:37 < aandrew> personally I have my entity declarations typically suffixed with _i or _o, but not always
2019-01-15T15:38:47 < aandrew> and if I can (if the design is big enough) I group shit into records and pass records in and out
2019-01-15T15:40:05 < dongs> ok i_blah o_blah seems to be pretty ok
2019-01-15T15:40:09 < dongs> or suffix
2019-01-15T15:40:51 < zyp> o_sole_mio
2019-01-15T15:44:21 < aandrew> I prefer suffixes because otherwise sorting gets fucked up (grouped by io rather than function)
2019-01-15T15:44:55 < karlp> whenever I use one way, I ened up wanting the other way..
2019-01-15T15:46:12 < aandrew> heh too true
2019-01-15T15:46:18 < aandrew> that's why I like records so much

2019-01-15T16:00:59 < bitmask> no, you fucked it up
2019-01-15T16:02:00 < rajkosto> how have i done this
2019-01-15T16:02:05 < bitmask> would it make sense for the integral term of a PID controller to be large on a very slow to respond system? 
2019-01-15T16:03:02 < specing> I have a china 100W boost for $3 that works properly, I'm sure you can make a working one as well
2019-01-15T16:03:03 < Cracki> scales are relative
2019-01-15T16:03:10 < specing> if not, you can always buy one from china ;)
2019-01-15T16:04:10 < Cracki> if by term you mean the state, then term * gain matters, but also time scales. if it vanishes again in a tenth of a second, it's nothing but a jolt
2019-01-15T16:04:51 < bitmask> well the P is 7 and the I is 1, thats not entirely true, recalculating P, I think it may be larger (or smaller :P)
2019-01-15T16:05:16 < Cracki> those values totally depend on the quantities you measure and the quantities you control
2019-01-15T16:06:02 < Cracki> and they're even relative to each other
2019-01-15T16:06:21 < Cracki> grab matlab or something, let it plot step response for you, fiddle with the parameters?
2019-01-15T16:06:23 < bitmask> yes yes I know
2019-01-15T16:06:39 < bitmask> but you can usually tell how a system will somewhat respond by the ratio
2019-01-15T16:06:43 < Cracki> anyway, the gains I have could be on the order of 0.1, 1, 10, 100, ...
2019-01-15T16:07:33 < Cracki> the gain corresponding to the springiness of the rotor is probably proportional to 1/deflection
2019-01-15T16:07:49 < marble_visions> aandrew: about what?
2019-01-15T16:07:53 < bitmask> why do you think it has anything to do with a rotor?
2019-01-15T16:07:54 < Cracki> so the harder I'd want the "spring" to be, the more that gain fucks off to big numbers
2019-01-15T16:08:03 < Cracki> I don't, but my controller is for a motor

2019-01-15T16:10:06 < bitmask> I guess I'll just try it out
2019-01-15T16:10:23 < bitmask> that seems a bit more reasonable
2019-01-15T16:11:47 < Cracki> calculation according to that famous rule of thumb?

2019-01-15T16:12:15 < Cracki> oh boy
2019-01-15T16:12:45 < bitmask> its tough when my response curve looks like this: https://i.imgur.com/kJZ8sBI.png
2019-01-15T16:13:22 < Cracki> perhaps try to model the "plant" so you don't have to wait... 10 minutes?
2019-01-15T16:13:31 < Cracki> what's the time scale for those
2019-01-15T16:13:58 < bitmask> thats almost 15 min
2019-01-15T16:14:32 < bitmask> well the I term should add up pretty quickly to get the system moving
2019-01-15T16:15:32 < Cracki> try a simple model of a mass and heat dissipation into environment
2019-01-15T16:16:25 < bitmask> with just a P controller I stay within 3 degrees of setpoint, I just wanted to try adding an I term to see what would happen, I dont really need this accuracy
2019-01-15T16:16:36 < Cracki> ic ic
2019-01-15T16:16:56 < Cracki> the worst that could happen is that the I oscillates... then you get pwm :>
2019-01-15T16:17:38 < bitmask> I'm already controlling it with a low frequency pwm, the PID controller sets the duty cycle
2019-01-15T16:17:56 < bitmask> and by low frequency I mean real low, the period is like 2 seconds or something
2019-01-15T16:18:32 < bitmask> I'll speed it up a little bit after some tests but its not really important
2019-01-15T16:22:18 < Cracki> I assume integration yields you x*t for t amount of time, i.e. controller runs once a second or multiplies by time step?
2019-01-15T16:23:50 < Cracki> then the integral term would grow "3 degrees" per second, or 180 per minute. if the plant responds that slowly, I'd say the gain will probably be a fraction
2019-01-15T16:24:13 < Cracki> do you scale your pwm to 0..1 or do you use integer range?
2019-01-15T16:24:34 < bitmask> I store it as a percentage between 0 and 100
2019-01-15T16:25:42 < bitmask> I wasn't really thinking about time with the integral term, usually the derivative is more time related but that doesnt mean the I is too
2019-01-15T16:25:51 < bitmask> I'll have to see how quickly it winds up
2019-01-15T16:26:03 < Cracki> it absolutely is, because the I term stands for enduring error
2019-01-15T16:26:32 < bitmask> yea I know, just forgot to think about it :)

2019-01-15T16:27:38 < Cracki> that test, is it heating with 100% duty cycle?
2019-01-15T16:27:46 < Laurenceb> so optimal in one case might oscillate/go mental in another case
2019-01-15T16:27:49 < bitmask> start is stable at 15% pwm, then jumped to 50% and watched
2019-01-15T16:27:59 < Cracki> ic
2019-01-15T16:28:02 < Laurenceb> maybe try a PID autotuning technique
2019-01-15T16:28:08 < bitmask> I used cohen coon

2019-01-15T16:28:21 < Laurenceb> but they are also very suboptimal
2019-01-15T16:28:46 < bitmask> even with just a randomly/intuitively chosen P controller I stayed within 3 degrees
2019-01-15T16:28:52 < Laurenceb> like my arm prodding device, optimal control was <25ms response time, PID was >450ms
2019-01-15T16:29:24 < Cracki> silicone isn't the best heat conductor but I can't think of a better alternative for the application
2019-01-15T16:29:54 < Laurenceb> PID was very rodust, but optimal control sometimes went mad
2019-01-15T16:29:55 < bitmask> not sure how it will respond when its actually tested in the cold and also held against my body

2019-01-15T16:30:11 < Cracki> what's "optimal control" in that sense
2019-01-15T16:30:16 < Cracki> more terms than PID?

2019-01-15T22:02:04 < zyp> hmm, apparently they are using efr32

2019-01-15T22:08:09 < ds2> wow the geckos are in use
2019-01-15T22:12:31 < zyp> hmm, those look cute
2019-01-15T22:12:57 < zyp> I wanna do some ZLL devices myself, maybe efr32 would be a good starting point
2019-01-15T22:13:10 < Steffanx> I opened up my gateway as well, dont remember whats in there. Probably the same thing
2019-01-15T22:13:18 < zyp> gateway has more stuff
2019-01-15T22:13:42 < zyp> https://github.com/basilfx/TRADFRI-Hacking <- according to this thing, the efr32s are unlocked, so they can just be dumped and reflashed
2019-01-15T22:14:08 < zyp> I guess to get started I can just buy a spare remote, crack it open and reflash it :)
2019-01-15T22:15:43 < qyx> zyp: what size is a single step on your staircase?

2019-01-15T22:16:23 < Steffanx> IS IT DONE YURI?
2019-01-15T22:16:26 < cnt> i'm fallong apart, or as blaxter would say, "muh sides"

2019-01-15T22:19:33 < Steffanx> What looks weird to me is the non-parallel handrails
2019-01-15T22:19:40 < Steffanx> or is that an optical illusion?
2019-01-15T22:20:00 < cnt> i cannot understand the dialect of idk
2019-01-15T22:20:11 < qyx> Steffanx: yeah lol
2019-01-15T22:20:12 < cnt> i'd assume its the .no language
2019-01-15T22:20:31 < qyx> they are awesome
2019-01-15T22:21:25 < zyp> Steffanx, when it curves 180 degrees, naturally the inner handrail is shorter than the outer while the height is the same, so naturally it's steeper
2019-01-15T22:22:02 < zyp> qyx, so 183.3mm height per step, 260mm depth
2019-01-15T22:22:22 < zyp> but I'm not sure where those 260mm are measured, if it's in center or what
2019-01-15T22:23:11 < zyp> https://portal.hagen.eu/ShowCompass3D/Default.aspx?OrderNum=349884
2019-01-15T22:23:35 < cnt> Elon was right
2019-01-15T22:23:44 < qyx> zyp: so they are not that steep
2019-01-15T22:23:48 < cnt> they drugged the kids, from there on maybe the pedo got his hand in
2019-01-15T22:24:16 < zyp> qyx, nah, it's just the angle the photo was taken that makes it look steep
2019-01-15T22:24:20 < cnt> has anyone here experienced a hard dose of ketamine
2019-01-15T22:24:21 < qyx> I have 240mm height per step, 250mm step size with 50mm overlap, so 200mm effective step size
2019-01-15T22:24:24 < zyp> it's perfectly natural to walk in
2019-01-15T22:24:32 < qyx> to the basement though

2019-01-16T00:31:17 < nn7> I have TrueStudio and CubeMX installed. I pulled up the f3discovery, checked the boxes for additional software to support the MEMS, generated the code....
2019-01-16T00:31:41 < nn7> and there's nothing MEMS anywhere in the code.
2019-01-16T00:32:20 < malinus> start with blinky
2019-01-16T00:32:31 < nn7> ok, how?
2019-01-16T00:33:06 < nn7> I feel like I'm missing something. Demo code anywhere?
2019-01-16T00:35:05 < specing> Write it. In assembly. While blindfolded.
2019-01-16T00:35:31 < nn7> That doesn't sound fun at all.
2019-01-16T00:36:42 < karlp> hrm, how does this hardware output nss work again?
2019-01-16T00:41:47 < nn7> Ah ha! STMCubeMX will download the demo programs but doesn't tell you where OR give you a graphical way to access them.
2019-01-16T00:42:11 < nn7> It's in the intuitive location C:\Users\me\STM32Cube\Repository\STM32Cube_FW_F3_V1.9.1\Projects\STM32F3-Discovery\Demonstrations
2019-01-16T00:47:26 < Steffanx> You can also download stm32cubef3 or something. It has demos/examples in the zip
2019-01-16T00:48:13 < Steffanx> Like examples for each peripheral
2019-01-16T00:48:24 < nn7> ok thanks
2019-01-16T00:48:36 < Steffanx> Using the HAL or (so called) LL drivers
2019-01-16T00:49:10 < Steffanx> It also includes examples for other boards but could still be useful for you

2019-01-16T02:25:15 < mawk> it's part of the bsp
2019-01-16T02:25:33 < mawk> but otherwise I'd just put true in the argument

2019-01-16T02:27:41 < mawk> search is just slow
2019-01-16T02:28:07 < mawk> it's an internal macro defined by freertos ports
2019-01-16T02:28:11 < mawk> apparently
2019-01-16T02:28:29 < mawk> maybe not internal, but part of the port
2019-01-16T02:28:39 < mawk> let's see in my stm32 port
2019-01-16T02:33:59 < mawk> ok karlp I got it

2019-01-16T02:38:47 < karlp> what, the "// Actual macro used here is port specific."
2019-01-16T02:39:00 < karlp> that's just the same thing it says on the original queue docs
2019-01-16T02:39:12 < karlp> still, we've found the macro,

2019-01-16T02:48:14 < karlp> fucking nucleo64 manual says that on the l073 boaard, there's a PB 6, which is SPI1 CS
2019-01-16T02:48:22 < karlp> PB6 doesn't have _anything_ spi on any AF.
2019-01-16T02:48:49 < dongs> do you evne care waht pin SPI_CS is unless you're slave?
2019-01-16T02:49:01 < dongs> its not like it will automatically assert/deassert it for you in master case?
2019-01-16T02:49:20 < karlp> this is for slave mode.
2019-01-16T02:49:25 < dongs> oh, rip in that case/
2019-01-16T02:49:45 < karlp> have a shitty little usb controlled spi master, now writing the spi slave.
2019-01-16T02:50:43 < karlp> made it a little hard on myself too, l1 on one side, with spi-v1, and l0 on the other, with spi-v2

2019-01-16T03:09:20 < dongs> so about my problem of stopped clock that I thought i had
2019-01-16T03:09:58 < dongs> https://i.imgur.com/b5qdVJA.png they stop teh clock for a bit between packets (about 127k clocks or so)
2019-01-16T03:10:08 < dongs> and i thought i would lose the last byte but
2019-01-16T03:10:22 < dongs> i guess when clock restarts, it shifts out the last byte that was still in shift register as normal
2019-01-16T03:10:44 < dongs> i need to sim what happens if i stop/restart clock followed by psync
2019-01-16T03:11:09 < dongs> now sure how i can 'stop' a clock that i have as always() in testbench
2019-01-16T03:11:21 < dongs> do i just make it 0 after some delay in code?
2019-01-16T03:12:40 < aandrew> that's why you don't clock with someone else's clock :-)
2019-01-16T03:13:11 < dongs> http://bcas.tv/paste/results/drhGEq97.html
2019-01-16T03:13:12 < dongs> lol plz
2019-01-16T03:13:22 < dongs> and what would you do if you had 125mhz serial data incoming
2019-01-16T03:13:27 < dongs> with a clock already
2019-01-16T03:13:31 < dongs> i dont think there's much that can be done
2019-01-16T03:14:00 < dongs> i think i'm like 99% clear on the conversion/capture. i see occasional bit errors
2019-01-16T03:14:02 < aandrew> I would use my system clock fasteer than that, say 200MHz or so, synchronize the incoming clock and capture it that way
2019-01-16T03:14:06 < dongs> i think thats just due to fucking transformer air wires
2019-01-16T03:14:12 < aandrew> just like I do for TDMA systems
2019-01-16T03:14:40 < aandrew> same with SPI slave implementations, UARTs, etc., etc.
2019-01-16T03:14:41 < dongs> that sounds like a lot of work
2019-01-16T03:14:46 < dongs> how do you "syncronize" a clock
2019-01-16T03:14:47 < aandrew> well doing it right is
2019-01-16T03:14:57 < aandrew> a clock is just like any other signal
2019-01-16T03:15:05 < aandrew> you run it through 2 FFs in series
2019-01-16T03:15:08 < karlp> hrm, getting lots of overruns and shit. get interrupts, so get .... something.
2019-01-16T03:15:15 < aandrew> when you see the synchronized signal go from high to low you sample the data bit
2019-01-16T03:15:24 < aandrew> alternatively
2019-01-16T03:15:48 < aandrew> you can run the serial-to-parallel with the incomign clock and stuff the data into a DCFIFO
2019-01-16T03:16:11 < aandrew> then pull the data out the other end, but if they're stopping the clock before you can get the last byte into the DCFIFO you're kind of screwed
2019-01-16T03:16:34 < dongs> aye, but anyway, i think i better just sim and see what actualyl happens with clock stoppage
2019-01-16T03:17:03 < Cracki> uh... why again do you have trouble? that clock only does an edge for each data bit
2019-01-16T03:17:08 < Cracki> no matter if it stops or not
2019-01-16T03:17:23 < aandrew> I think that's the first time in... over a decade? that I"ve ever seen you write "aye"
2019-01-16T03:17:31 < Cracki> if that's proper SPI, you as a receiver should not expect any clock past deasserted chip select
2019-01-16T03:17:35 < aandrew> I swear if you say m'ilady I'm going to kickban you
2019-01-16T03:17:42 < Cracki> arrr
2019-01-16T03:17:49 < aandrew> Cracki: I prefer not to fuck with DCFIFOs without a good reason
2019-01-16T03:18:00 < Cracki> wat even are *DC* fifos
2019-01-16T03:18:07 < dongs> blah. of course zeroing it doesnt work
2019-01-16T03:18:08 < aandrew> dual clock FIFOs
2019-01-16T03:18:10 < dongs> dual clock
2019-01-16T03:18:17 < dongs> an altera shit but xilinx has something similar
2019-01-16T03:18:20 < Cracki> and anyway, upon the last clock edge of the last bit, you should have a full byte, no?
2019-01-16T03:18:31 < dongs> cracki, no
2019-01-16T03:18:57 < Cracki> and that's because why? do you rely on more clock after the last bit?
2019-01-16T03:19:13 < dongs> https://i.imgur.com/Qmjz1vZ.png i'm doing serial>parallel conversion
2019-01-16T03:19:22 < dongs> data is 3rd from bottom 
2019-01-16T03:19:32 < dongs> clock for that data is above it
2019-01-16T03:19:32 < Cracki> yeah sure, a shift register, and counting bits, and latching data and stuff
2019-01-16T03:19:35 < dongs> yeah

2019-01-16T03:20:40 < dongs> i'm not sure if it does! thats what im trying to simulate
2019-01-16T03:20:49 < Cracki> I understand you use that clock to drive your stuff, but does your stuff need more than one clock edge to do whatever it does per bit?
2019-01-16T03:20:50 < dongs> i cant make fucking veriblog pause the clock tho
2019-01-16T03:20:54 < dongs> no
2019-01-16T03:20:54 < Cracki> hm
2019-01-16T03:21:02 < Cracki> how do you define your stimulus clock?
2019-01-16T03:21:16 < dongs> just always #5 clk_in = ~clk_in;
2019-01-16T03:21:21 < Cracki> ah...
2019-01-16T03:21:36 < Cracki> make a counter
2019-01-16T03:21:51 < Cracki> switch clock on or off after it's counted down to zero, then reload?
2019-01-16T03:22:03 < dongs> in that always thing?
2019-01-16T03:22:07 < dongs> ok lemme think
2019-01-16T03:22:15 < dongs> increment counter always,
2019-01-16T03:22:23 < dongs> if it hits number, stop clock, or else do normal invert on each cycle
2019-01-16T03:22:28 < Cracki> uh, I'd keep that ~clk_in thing, but then modulate it
2019-01-16T03:22:29 < dongs> ok. lemme try that.
2019-01-16T03:22:39 < dongs> oh hm
2019-01-16T03:22:57 < dongs> so you mean make anotehr reg for clock
2019-01-16T03:23:00 < dongs> that inverts #5
2019-01-16T03:23:10 < dongs> and then if condition, output zero or else output that clock
2019-01-16T03:23:11 < dongs> k
2019-01-16T03:23:13 < Cracki> and gate basically, with one input being a counter compare
2019-01-16T03:23:16 < dongs> yes
2019-01-16T03:23:36 < Cracki> I'd go that way, but I have no clue if that's sensible or if there's a smarter way

2019-01-16T03:29:53 < dongs> ok it sorta works now i gotta count some clocks

2019-01-16T09:53:31 < upgrdman> like, you normally use 2 rails... but i want to use 1, and the load is pretty light. but not sure if the carriage block will pivot much if there is no second rail to stabilize that axis

2019-01-16T10:47:30 < dongs> yeah but keyed header takes up way too much fuckign sapce
2019-01-16T10:47:45 < zyp> just use the one that's only partly shrouded
2019-01-16T10:48:13 < zyp> https://t1.daumcdn.net/cfile/tistory/140CEE1E4CE1F5BA32 <- this shit
2019-01-16T10:48:33 < zyp> doesn't take more area than an unshrouded one
2019-01-16T10:48:58 < zyp> or drop the entire connector and do tag-connect, they are also keyed

2019-01-16T11:20:23 < dongs> i can get china to snip 2x5 headers for liek $1 for 100
2019-01-16T11:20:30 < dongs> but that shrounded stuff is probly $10 for 1
2019-01-16T11:24:44 < qyx> hm those china spring 433MHz antennas are like ~20dB worse than a 165mm piece of wire

2019-01-16T11:28:57 < karlp> hrm, I think that's actually for some custom thing though, not a normal idc

2019-01-16T12:14:16 < PaulFertser> dongs: suppose I have a microsoft sticker on an old laptop. Product number is clearly readable, product name is completely invisible by now. Why the hell microsoft doesn't let me enter this number somewhere so that I learn what particular type of the professional OS that is?
2019-01-16T12:25:00 < karlp> qyx: no idea, I was trying tha tlast night and getting overruns and not really working, but it was day 0 of trying spi slae stuff.
2019-01-16T12:25:11 < karlp> for my master stuff I just use spi_xfer.
2019-01-16T12:25:45 < karlp> PaulFertser: it probably does, just unable to find it.
2019-01-16T12:26:09 < karlp> and I think they often say, "oh, you're not allowed to _reinistall_ that, that was for oem bundling only"
2019-01-16T12:26:49 < PaulFertser> karlp: do they really? The HDD died, so how the hell am I not supposed to reinstall it?
2019-01-16T12:28:23 < karlp> you mena, you want to use an disk that 's not original? :)
2019-01-16T12:28:32  * karlp has no idea.
2019-01-16T12:30:09 < qyx> spi_xfer corrupts fifo or what because it transfers more than a single byte
2019-01-16T12:30:28 < qyx> and if you select 8bit transfer the bytes are messed somehow
2019-01-16T12:30:29 < PaulFertser> Need dongs to rage
2019-01-16T12:31:24 < cnt> set a trap on freelancer
2019-01-16T12:33:18 < karlp> if spi_xfer doesn't work at all on the v2 parts, then that's just a bug.
2019-01-16T12:33:29 < karlp> but how does it transfer multiple?
2019-01-16T12:34:21 < zyp> it's the fifo thing
2019-01-16T12:34:41 < zyp> if you have it configured to 8 bit per transfer and you do a 16/32 bit register write, it puts two transfers into the fifo
2019-01-16T12:35:15 < zyp> so you need to explicitly do 8-bit register writes
2019-01-16T12:35:43 < zyp> https://cgit.jvnv.net/laks/commit/?id=d2086a59c15125a0503649ecbadadfdb9fc23b2f
2019-01-16T12:36:51 < karlp> is this the thing with the SPI_DR definitions being MMIO16 or something?
2019-01-16T12:37:25 < karlp> is this still not actually fixed for spi v2?
2019-01-16T12:37:41 < qyx> now there are two functions, send and send8
2019-01-16T12:37:47 < qyx> the same for read
2019-01-16T12:37:51 < qyx> but xfer is only one
2019-01-16T12:38:22 < karlp> oh. joy
2019-01-16T12:38:47 < karlp> guess you have to use them manually then I suppose.
2019-01-16T12:39:22 < qyx> yeah, I am doing that, but now I am debugging why I get things like 0x3a3a, 0x7474 and such from an IRQ status registers
2019-01-16T12:39:37  * karlp shrugs. you're ahread of me here sorry
2019-01-16T12:40:25 < qyx> but fuk things because there are many changes, I have nucleo-F411 with RFM69 working and L432 with SX1231 not
2019-01-16T12:40:58 < qyx> and basically all works except some minor details which makes the whole thing not funvtional
2019-01-16T12:41:46 < qyx> like packet sent bit is never set for some reason despite all other working properly and the packet is received
2019-01-16T12:47:12 < jpa-> PaulFertser: what does it matter? AFAIK you can still install windows 10 with just about any key
2019-01-16T12:48:19 < PaulFertser> jpa-: vista is not upgradable to 10 afaik. And that laptop is kinda old, I'm not sure it's worth trying w10 on it due to all those driver issues I've heard about.
2019-01-16T12:49:03 < jpa-> true, though windows 10 works fine on my 2007-bought acer laptop
2019-01-16T12:49:22 < jpa-> (as in, as well as the vista it came with ever did)
2019-01-16T12:49:41 < PaulFertser> Hm, that's some "packard bell" thing, was high-end back then, came with vista. Not legally upgradable to w10 last time I checked, because it's vista, not w7.
2019-01-16T12:52:31 < jpa-> https://www.microsoft.com/en-us/software-download/windows7   you could try if this accepts the key, though if it is a vista key it probably won't
2019-01-16T12:53:05 < jpa-> windows 10 isos you can get without key even, so you'll end up installing first and then find out your license doesn't work
2019-01-16T12:53:28 < PaulFertser> I'll just install Debian with KDE on it but I have a feeling my sister might need a backup windows system so if there's a key why not install it but wtf does microsoft make it so non-obvious.
2019-01-16T12:53:56 < jpa-> because they have no money to gain from people re-using old license keys
2019-01-16T12:54:01 < PaulFertser> Well, I know the answer but I'd still like to hear the other side.

2019-01-16T14:58:00 < aandrew> so all your signals have nice reference nearby and have some minor shielding
2019-01-16T14:58:05 < dongs> for serial?
2019-01-16T14:58:08 < dongs> parallel lloosk ok
2019-01-16T14:58:19 < aandrew> for 125MHz signals, doesn't matter what is on it
2019-01-16T14:58:24 < aandrew> 125MHz digital*
2019-01-16T14:58:41 < dongs> oh shit
2019-01-16T14:58:46 < dongs> i could use that flexible wire i got
2019-01-16T14:58:50 < specing> why use FT* anyway
2019-01-16T14:58:51 < dongs> i think its 8 or so conductor
2019-01-16T14:58:53 < specing> they are overpriced
2019-01-16T14:59:01 < dongs> specing: suggestions welcome
2019-01-16T14:59:02 < specing> better write a stm32f032 usb
2019-01-16T14:59:08 < dongs> need up to 100mbit parallel input
2019-01-16T14:59:10 < aandrew> you don't have old IDE or floppy disk cables hiding somewher
2019-01-16T14:59:19 < dongs> aandrew: . those are garbage
2019-01-16T14:59:21 < aandrew> wait
2019-01-16T14:59:23 < specing> dongs: oh that is going to get expensive
2019-01-16T14:59:32 < specing> dongs: ethernet maybe?
2019-01-16T14:59:46 < aandrew> 100mbit? your parallel clock is 12.5MHz?

2019-01-16T15:00:03 < dongs> aandrew: 16.something
2019-01-16T15:00:07 < aandrew> yes ethernet would work, each pair should be ground+signal
2019-01-16T15:00:09 < dongs> its not continous tho
2019-01-16T15:00:19 < aandrew> it's something, but not as good as ribbon I don't think
2019-01-16T15:00:27 < dongs> ive got ribbon.
2019-01-16T15:00:30 < dongs> negroing it up.
2019-01-16T15:00:44 < aandrew> these aren't balanced signals or anything, I'm just trynig to keep the signals from interfereing and giving them a good reference
2019-01-16T15:00:47 < aandrew> I guess TP is the same
2019-01-16T15:01:08 < aandrew> since the different twists would offer isolation and the refernce doesn't gie a shit if it's twisted around the signal or beside it
2019-01-16T15:01:18 < specing> Oh I know
2019-01-16T15:01:21 < specing> use FX2LP
2019-01-16T15:01:32 < aandrew> is it also possible that your rx signal may have periodic errors in it?
2019-01-16T15:01:36 < specing> cypress cheap USB 2.0  8051 mcu
2019-01-16T15:01:41 < aandrew> specing: yep we all know it well
2019-01-16T15:01:42 < dongs> i know i could, the problem with that is 8051
2019-01-16T15:01:44 < aandrew> dongs loves the 8051
2019-01-16T15:01:52 < aandrew> you know how I know?
2019-01-16T15:01:54 < aandrew> keil loves the 8051
2019-01-16T15:01:56 < dongs> and i dont wanna use fx3 beacuse.. you know what?
2019-01-16T15:01:59 < aandrew> and dongs loves the keil
2019-01-16T15:02:03 < aandrew> fx3 is shit
2019-01-16T15:02:05 < dongs> its toolchain is fucking gcc shitware opensores nigger faggot shit
2019-01-16T15:02:07 < aandrew> holy fuck stay the fuck away
2019-01-16T15:02:12 < aandrew> that's not even the issue
2019-01-16T15:02:20 < dongs> no, thats the biggest issue :)
2019-01-16T15:02:29 < aandrew> it was so much fucking work getting the gpif2 configured, and it's arm7tdmi and .. ugh
2019-01-16T15:02:38 < Haohmaru> aww, dongs is allergic
2019-01-16T15:03:06 < dongs> yeah the gpif shit is just what teh fuck ever
2019-01-16T15:03:13 < dongs> and every single engineer at cyupress is a fucking indian
2019-01-16T15:03:17 < dongs> good luck getting any halp from them
2019-01-16T15:03:22 < aandrew> yes that is true
2019-01-16T15:03:27 < specing> Lol dongs 
2019-01-16T15:03:30 < specing> gcc owns
2019-01-16T15:03:44 < aandrew> I had no real support for FX3, no real support for PSoC... that's a fucking good point
2019-01-16T15:03:50 < specing> I cannot use anything else than gcc
2019-01-16T15:04:28 < aandrew> 24h turn for every question and at least 4 turns to get them to give more of an answer than "look at TRM" or telling me something COMPLETELY fucking unrelated to the issue

2019-01-16T15:05:13 < aandrew> I gotta get me a chinagirl

2019-01-16T15:05:38 < dongs> wat 
2019-01-16T15:05:41 < dongs> did you dump your CE trash
2019-01-16T15:05:54 < dongs> or is taht EE
2019-01-16T15:06:00 < aandrew> what?
2019-01-16T15:06:06 < dongs> central/eastern europe
2019-01-16T15:06:13 < aandrew> heh
2019-01-16T15:06:16 < aandrew> romania yes
2019-01-16T15:06:36 < dongs> i'd watch al lyour creditcards for the next several years
2019-01-16T15:06:46 < dongs> gunna git haxed
2019-01-16T15:07:07 < aandrew> didn't dump her. after 13y it's ... well I think we are sick of each other's shit and even if I fixed the shit she loathes about me she's said plainly and simply that she's not gonna change
2019-01-16T15:07:19 < aandrew> I'm sad but I'll figure it out, this isn't my first divorce
2019-01-16T15:07:24 < Cracki> so... you guys don't like cypress, which means psoc, fx3, fx2?
2019-01-16T15:07:27 < dongs> sounds about right
2019-01-16T15:07:41 < dongs> the only good support i got from cypress was on parts they bought from uh.. i forgot who
2019-01-16T15:07:45 < dongs> ASI-related shit
2019-01-16T15:07:53 < dongs> it was from indians but they knew what they were doing
2019-01-16T15:07:54 < aandrew> nah she's not like that. one thing I have always admired about her is that she's honest and would rather attack head-on than be sneaky
2019-01-16T15:08:00 < dongs> fx2/psoc shit is just fuck offff
2019-01-16T15:08:01 < aandrew> Cracki: correct
2019-01-16T15:08:19 < Cracki> congrats on the freedom btw

2019-01-16T15:10:02 < Cracki> wait, "honest", I remember statements to the contrary
2019-01-16T15:10:15 < Cracki> maybe that's just the gaslighting talking
2019-01-16T15:11:12 < aandrew> well there's gaslighting yes
2019-01-16T15:11:31 < aandrew> but I'm talking about screwing out of money or property or shit like that
2019-01-16T15:11:49 < aandrew> gaslighting was more about "no, you said the sky was green" or "I never said you were the devil"
2019-01-16T15:12:04 < dongs> i wanna hear stories of laurence/b/ divorces

2019-01-16T15:13:06 < dongs> wihtout any context or explanation
2019-01-16T15:13:10 < dongs> sometimes says soemthing like "my sides"
2019-01-16T15:13:17 < PeterM> should i leave him on ignore?
2019-01-16T15:13:18 < dongs> and then yanks ethernet out of his shitty lunix esktop and leaves
2019-01-16T15:13:33 < PeterM> its keeping the chat clean
2019-01-16T15:13:35 < dongs> i dont think you'd be missing any quality chats if you didnt
2019-01-16T15:13:41 < Cracki> oh right, dongs, there was some ohsix who wants to throw money at you
2019-01-16T15:13:42 < PeterM> fair enough
2019-01-16T15:13:49 < dongs> Cracki: yea, hes on ignore as well

2019-01-16T15:20:56 < aandrew> ahh

2019-01-16T16:24:09 < karlp> hrm, that's actually less useful than I thought
2019-01-16T16:24:21 < karlp> downgrade r2 to 1 useful...

2019-01-16T16:29:01 < karlp> we're sure not here for the blaxter links.
2019-01-16T16:30:16 < Haohmaru> well i meant that they are rarer than gold
2019-01-16T16:30:27 < karlp> so, not really that rare then.
2019-01-16T16:30:59 < Haohmaru> but burried in sh*t
2019-01-16T16:33:13 < rajkosto> whats faster, jtag or swdio ?
2019-01-16T16:33:14 < karlp> well yeah, not much surface gold these days inthe world either...
2019-01-16T16:33:25 < karlp> rajkosto: do you prefer blue or red?
2019-01-16T16:33:42 < rajkosto> jtag has to run at 1MHz only for some reason on stm32 and its quite slow
2019-01-16T16:33:50  * karlp laughs
2019-01-16T16:33:56 < karlp> "has to" "for some reason"

2019-01-16T16:34:04 < dongs> naisu
2019-01-16T16:34:13 < karlp> switching to swd won't fix intrinsic problems.
2019-01-16T16:34:23 < rajkosto> its because of clock tree setup when the chip is not running fully etc

2019-01-16T16:36:58 < rajkosto> it seems swd is actually faster
2019-01-16T16:37:00 < aandrew> STM32F107 has ethernet
2019-01-16T16:37:09 < aandrew> only LQFP though
2019-01-16T16:37:19 < aandrew> oh no there's a larger pkg bga
2019-01-16T16:38:59 < aandrew> F207 has a nicer pkg
2019-01-16T16:39:22 < aandrew> er no, it's .4mm pitch bga

2019-01-16T16:50:48 < kakimir> so you listen the free musics without high bandwidth
2019-01-16T16:50:53 < Haohmaru> there's soundcloud and similar websites
2019-01-16T16:51:27 < kakimir> I need one kick ass song
2019-01-16T16:51:38 < kakimir> that I can play on repeat for next 4 days
2019-01-16T16:52:42 < karlp> mountain - stereolab
2019-01-16T16:52:56 < kakimir> that name sounds promising
2019-01-16T16:53:48 < dongs> kakimir: yeah, isntall the fucking shit called newpipe
2019-01-16T16:53:52 < dongs> and that can play audio only
2019-01-16T16:53:55 < Haohmaru> kakimir what genre?
2019-01-16T16:54:02 < dongs> https://newpipe.schabi.org/
2019-01-16T16:54:08 < dongs> it can also play jewtub in a popup window
2019-01-16T16:54:16 < dongs> or in background as audio only etc
2019-01-16T16:54:28 < Steffanx> Fancy.
2019-01-16T16:54:32 < Steffanx> Buying
2019-01-16T16:54:36 < dongs> . its free
2019-01-16T16:54:45 < dongs> (and opensores)
2019-01-16T16:54:46 < Steffanx> Oh no playstore app?
2019-01-16T16:54:50 < dongs> its just apk
2019-01-16T16:54:55 < Cracki> videos with just a static "cover" actually compress very well. most of the bitrate is spent in the audio track
2019-01-16T16:54:58 < dongs> f-droid is some opensores repository
2019-01-16T16:55:03 < dongs> because ~freeduhms~
2019-01-16T16:55:07 < dongs> but you can just download .apk there
2019-01-16T16:55:23 < Steffanx> Meh.
2019-01-16T16:55:37 < Cracki> but if you have a video with some kind of bargraph effects or even real camera footage... yeah
2019-01-16T16:56:05 < Cracki> you can try youtube-dl. frequently youtube hosts audio and video separately, which ytdl can select
2019-01-16T16:56:44 < karlp> as can newpipe...
2019-01-16T16:56:57 < karlp> and youtube-dl still needs a player right?
2019-01-16T16:57:22 < kakimir> youtube hosts audio only too?
2019-01-16T16:57:26 < Cracki> yes
2019-01-16T16:57:29 < kakimir> why?
2019-01-16T16:57:44 < Cracki> dunno, seems related to streaming it easier
2019-01-16T16:57:57 < Cracki> or the player selects what the platform can play
2019-01-16T16:58:16 < Cracki> (or has hw codecs for), aac, opus, ... h264, h265, vpx, ...
2019-01-16T16:59:47 < kakimir> whoops I had youtube autoplay on
2019-01-16T16:59:55 < kakimir> that's 50MB unnoticed
2019-01-16T17:00:17 < Steffanx> Hows china today?
2019-01-16T17:00:45 < Cracki> but thanks for the app recommendation, I'm sure I'll be using that
2019-01-16T17:02:28 < karlp> hrm, 60V/1250A.
2019-01-16T17:02:32 < karlp> that's going to be fun.

2019-01-16T17:21:58 < kakimir> little known fact: sh had a couple of decaides back 30k population
2019-01-16T17:22:07 < kakimir> this place is completelly new
2019-01-16T17:22:39 < kakimir> but also everything but really nice places look old
2019-01-16T17:23:47 < kakimir> 5years old factory can look like it was made in 60s
2019-01-16T17:28:31 < kakimir> taste of ginger and frying is in everything
2019-01-16T17:31:21 < Cracki> old because grimy, or anachronistic architecture?
2019-01-16T17:32:22 < mitrax> beware of elevators :p
2019-01-16T17:33:01 < Cracki> did one bite you?
2019-01-16T17:33:59 < kakimir> I'm in 5 star hotel
2019-01-16T17:34:10 < kakimir> this place has Kone elevators
2019-01-16T17:34:19 < mitrax> no but in some of those buildings the elevators were making screechy noises and were obviously not maintained
2019-01-16T17:34:59 < kakimir> in factories big cargo elevators are used to enter facilities
2019-01-16T17:37:03 < kakimir> in one place the door made banging noises and hardly closed
2019-01-16T17:37:32 < mitrax> that's what i'm refering to :)
2019-01-16T17:37:42 < aandrew> 2 or 3 errors per gigabit? that's not acceptable? are you sure the errors are not coming from the source?
2019-01-16T17:39:21 < dongs> aandrew: yeah not from source. its same bit shift stuff
2019-01-16T17:39:28 < dongs> i dont carea bout these
2019-01-16T17:39:32 < dongs> this shows proof of concept works
2019-01-16T17:39:32 < aandrew> ok

2019-01-16T17:39:56 < Cracki> time to ass error correction maybe :P

2019-01-16T17:42:01 < kakimir> traffic is not as bad as I expected
2019-01-16T17:42:24 < kakimir> even after being in traffic crash today I think it's pretty fine
2019-01-16T17:43:30 < kakimir> I saw the crash to occur 2 seconds before it did but I didn't want to distract the driver who didn't talk english
2019-01-16T17:44:34 < kakimir> things like traffic lights are respected
2019-01-16T17:45:07 < kakimir> and walkways usually but if the driver uses horn it means don't fucking go there
2019-01-16T17:45:18 < aandrew> so the bit shifts are likely do to the HDL design and not SI is what you're saying
2019-01-16T17:45:19 < day> kakimir: you were in the car?

2019-01-16T22:25:20 < specing> NMI is up
2019-01-16T22:25:23 < Cracki> wondering how to squeeze single float to ascii decimal into few bytes of code
2019-01-16T22:25:59 < Cracki> that avr libc wants a thousand bytes extra for the privilege
2019-01-16T22:26:45 < specing> Cracki: just dump it in hex
2019-01-16T22:26:48 < Cracki> I think I'm gonna go with a slow algorithm that's simple at least
2019-01-16T22:27:22 < Cracki> I know there are hex floats but I'm not sure I can make the boss/customer eat that
2019-01-16T22:28:14 < Cracki> looky, c++ has them starting from c++17
2019-01-16T22:30:17 < specing> Why are you doing floats on an avr?
2019-01-16T22:30:23 < specing> in a stm32 channel?
2019-01-16T22:30:36 < Cracki> just giving them a GUI would be easier but I can tell they want a serial text interface as well
2019-01-16T22:30:52 < specing> you can tell?
2019-01-16T22:30:57 < specing> in written format?

2019-01-16T22:48:57 < Steffanx> Hows your avr doing today specing ?
2019-01-16T22:49:07 < Steffanx> iirc we met for the first time in #avr
2019-01-16T22:50:13 < specing> no usable toolchain Steffanx, otherwise fine
2019-01-16T22:50:40 < specing> and I've decided to migrate to cortex-m*, anyway
2019-01-16T22:52:35 < Steffanx> :)
2019-01-16T22:56:20 < specing> and AVRs were expensive to debug (dragon was like 50 eur or sth, while st-link is everywhere on cheap kits)
2019-01-16T22:56:26 < specing> not that I need debugging nowadays

2019-01-16T23:23:58 < specing> Does anyone know how to mix .rodata and .text sections with gcc? Right now there is stuff in .rodata that is accessed by a pointer stored together with the code, but I'd like it to skip that if possible
2019-01-16T23:30:49 < zyp> why?
2019-01-16T23:32:33 < specing> why not?
2019-01-16T23:32:57 < specing> saves some code space and makes things faster. win-win
2019-01-16T23:33:46 < zyp> how do you figure?
2019-01-16T23:34:14 < zyp> is this like a small object in .rodata and you want it emitted directly into the constant pool rather than a pointer to it?
2019-01-16T23:34:25 < specing> yes, e.g. strings
2019-01-16T23:34:37 < zyp> strings are not small objects
2019-01-16T23:34:43 < specing> why not?
2019-01-16T23:36:22 < specing> and it does not matter. they are both accessed indirectly and the processor does not care whether the pointer to them is pc+0xwhatever or .rodata+0xwhateverelse
2019-01-16T23:37:05 < zyp> so what's the problem then?
2019-01-16T23:38:55 < specing> double indirection
2019-01-16T23:39:22 < specing> I'd like to save the additional load and 4 bytes of flash
2019-01-16T23:40:36 < karlp> is it actually _doing_ double indirection?
2019-01-16T23:40:43 < specing> yes
2019-01-16T23:40:49 < specing> I checked disassembly
2019-01-16T23:40:56 < karlp> just checking, lots of people assume things like that witthout looking at the dissassembly
2019-01-16T23:41:11 < zyp> loading a pointer from the constant pool and generating a pointer to the constant pool shouldn't be all that different, speed wise
2019-01-16T23:41:18 < karlp> Personally, I justt love the "not that I need debugging nowadays" line
2019-01-16T23:41:49 < zyp> and I don't think there's any way to ask the compiler to throw a string into the constant pool either
2019-01-16T23:41:53 < specing> ldr rsth, pc+...  followed by a branch with link
2019-01-16T23:42:13 < specing> zyp:it is different, it increases memory pressure and inflates storage requirements
2019-01-16T23:42:27 < specing> karlp: well, it is actually true :)
2019-01-16T23:42:28 < karlp> Thorn: nice jeanette pick :)
2019-01-16T23:43:06 < zyp> specing, well, in theory, but have you measured the difference in practice?
2019-01-16T23:43:28 < specing> zyp: no, I only checked disassembly
2019-01-16T23:44:02 < zyp> the constant pool is local, so if you're on a highend chip, it's probably already in cache so the load just fetches it from there
2019-01-16T23:44:33 < specing> I'm on m0: stm32f072
2019-01-16T23:44:46 < zyp> also, having a shared string pool in .rodata lets the compiler deduplicate strings
2019-01-16T23:45:25 < zyp> and first of all
2019-01-16T23:45:50 < specing> zyp: It doesen't have to store all strings with program code. Just the ones that are not accessed from outside the function
2019-01-16T23:45:50 < zyp> what the fuck are you doing with strings that makes you worry so much about performance that you are microoptimalizing it?
2019-01-16T23:46:22 < specing> I like reading disassembly, zyp. Having double indirections makes it harder to follow
2019-01-16T23:46:33 < zyp> use a better disassembler
2019-01-16T23:46:51 < specing> ...
2019-01-16T23:46:55 < karlp> "I don't debug" "I read disassembly".... ?

2019-01-16T23:47:43 < zyp> no really, if you're doing some serious digging in disassembly, IDA helps a lot
2019-01-16T23:48:43 < specing> binutils objdump generates nice disassembly with high level code mixed in
2019-01-16T23:48:50 < specing> so I've got that covered

2019-01-17T11:12:30 < jpa-> marble_visions: i put const before the type in simple cases; but sometimes you have stuff like  void * const *arg   that looks weird no matter what
2019-01-17T11:13:31 < zyp> I always put const first
2019-01-17T11:13:43 < zyp> i.e. const foo_t foo;
2019-01-17T11:15:20  * Haohmaru too
2019-01-17T11:15:26 < zyp> the only sensible exception would be foo_t* const foo; which means that the pointer is const, not the base type, but I can't really imagine any situations where it would make sense to declare a const pointer

2019-01-17T11:17:31 < dongs> are you one of those fags that aligns variable names on the longest type name before it

2019-01-17T11:17:44 < dongs> or wahtever
2019-01-17T11:18:37 < Haohmaru> i do it if i feel so, not always
2019-01-17T11:20:00  * Haohmaru strips away dongs' indentation
2019-01-17T11:21:02 < Steffanx> It makes muh structs look nice
2019-01-17T11:22:46 < marble_visions> const type reads better, but having type const is then uniform with the other times where you have type * const
2019-01-17T11:23:26 < Haohmaru> sprinkle const everywhere untill it stops compiling
2019-01-17T11:23:33 < Haohmaru> also constexpr
2019-01-17T11:23:37 < Haohmaru> mmm tasty
2019-01-17T11:24:00 < zyp> marble_visions, but when do you ever have type * const in real world code?
2019-01-17T11:25:04 < marble_visions> zyp: marks intention, but doesn't serve the API
2019-01-17T11:25:16 < marble_visions> means you're not going to modify the pointer
2019-01-17T11:26:53 < zyp> I know what it means, it just doesn't seem very useful
2019-01-17T11:28:19 < marble_visions> you can get compiler warnings if you try to do *var = blah, instead of var = blah
2019-01-17T11:28:32 < zyp> const is useful on stuff that's pass-by-reference because you know the function you call won't edit the original
2019-01-17T11:28:55 < marble_visions> yes, that's more important
2019-01-17T11:28:59 < zyp> but not very useful on stuff that's pass-by-value, since in that case changing the copy doesn't change the value anyway

2019-01-17T11:29:52 < zyp> and you generally don't pass pointers by reference unless as part of a struct, in which case it may make sense for the struct to be const
2019-01-17T11:30:55 < zyp> mixing up *var = blah and var = blah should give errors anyway, as *var and var are different types

2019-01-17T12:57:21 < PeterM> so, ive got a board that can use an ACS758/ACS770, the board works fine with either of them. the ACS758 is NRND but still in production. the ACS770 is "new" and also inproduciton. the ACS758 is cheaper than the ACS770, does anyone see any problems with using the ACS758 until its out of produiction?
2019-01-17T13:01:04 < jpa-> well, if you have tested with both, i can't see why not; i assume you have noted the differences like different allowed voltage ranges etc.
2019-01-17T13:07:30 < PeterM> yeah, they are very very close in performance, the older  part is ever so slightly faster, and the new part has ever so slightly better offset, but both are well within my specs and have used both for testing (even mixed and matched)
2019-01-17T13:08:03 < PeterM> i think they're both fine, i was jsut double checking

2019-01-17T13:48:11 < dongs> y5v
2019-01-17T13:48:24 < englishman> cuz a) everything is calibrated b) at room temp

2019-01-17T13:48:42 < PeterM> yeah, also if not much dc bias y5v is fine
2019-01-17T13:49:09 < PeterM> and at super high dc bias, even x7r is garbage so what does it matter?
2019-01-17T13:49:11 < englishman> 10u50v will be expensive
2019-01-17T13:49:17 < dongs> certainly

2019-01-17T14:25:47 < PeterM> dongs: yeah sorta, same package, but the panasonic fc series is a normal wet electrolyte capacitor not a polymer electrolyte
2019-01-17T14:25:48 < karlp> and keep the old struct around so I can neatly do teh load/save properly.
2019-01-17T14:26:31 < dongs> PeterM: oh, isee. so the dry ones are better or wat
2019-01-17T14:27:36 < karlp> better in every way
2019-01-17T14:27:41 < PeterM> the dry ones are really really low ESR compared to the wet ones
2019-01-17T14:28:20 < dongs> how about case sizes
2019-01-17T14:28:29 < dongs> do tehy follow the same cas ABCD whaetver shit like panasonic stuff?
2019-01-17T14:28:30 < karlp> wet are cheaper, and higher voltages. 
2019-01-17T14:28:34 < dongs> ah
2019-01-17T14:28:44 < dongs> cheaper is what i need then :D
2019-01-17T14:29:03 < karlp> they're still procs and cons, 
2019-01-17T14:29:07 < karlp> wet dry out though, 
2019-01-17T14:29:20 < PeterM> if its the output of a dc-dc and you're currently using ceramics, you can use a very small high voltage alu poly and come out ahead though
2019-01-17T14:29:36 < PeterM> because of the low esr, you need a much smaller cap comapred to wet
2019-01-17T14:30:34 < karlp> tant polys are pretty mcuh always better than tants though, iirc

2019-01-18T01:12:00 < zyp> but I wanted something faster and more reliable, so I picked up a pair of these
2019-01-18T01:12:47 < zyp> got a friend living right up the street, so now I'm getting internet from there instead :)
2019-01-18T01:13:28 < zyp> originally I were going to get a pair of nanostations instead, distance is only 65m or so according to google maps, but they were not in stock, so I went for the second cheapest instead
2019-01-18T01:14:12 < zyp> gain on these things are so high they warn about possible receiver saturation even on lowest tx power
2019-01-18T01:14:39 < zyp> but link seems to be perfectly stable and fast enough to saturate my friends connection :p

2019-01-18T05:36:26 < Cracki> is there a picture of his companies' stocks dropping?
2019-01-18T05:36:46 < Cracki> finding the date and looking it up is a little inconvenient
2019-01-18T05:37:45 < Cracki> Musk calls the Guardian the world’s ‘most insufferable newspaper’ https://www.theguardian.com/technology/2018/sep/07/tesla-chief-elon-musk-smokes-marijuana-on-live-web-show
2019-01-18T05:40:41 < Cracki> oh well, 7 sep 2018, it took a dip but bounced back up the next day
2019-01-18T05:41:09 < Cracki> october looks "worse"
2019-01-18T05:52:46 < dongs> http://bcas.tv/paste/results/1IQuqb48.html zyp i spent an hour yesterady trying to debug this
2019-01-18T06:07:24 < mawk> packet is char * right dongs ?
2019-01-18T06:07:28 < dongs> uint8 yeah
2019-01-18T06:07:31 < mawk> right
2019-01-18T06:07:36 < dongs> and p is uint8 ptr
2019-01-18T06:07:41 < dongs> thats not where the issue is
2019-01-18T06:08:10 < dongs> packet is uint8[ts_read_size] and p is uint8 *p
2019-01-18T06:09:24 < mawk> shouldn't you be moving at packet + remaining at the end ?
2019-01-18T06:09:35 < dongs> i thought so to but no, p is a dynamic pointer.
2019-01-18T06:09:51 < dongs> at the end, its pointing to <= TS_PACKET_SIZE until end of packet[]
2019-01-18T06:10:02 < dongs> so the memmove is correct.
2019-01-18T06:10:05 < dongs> it needs to move that tail to the top
2019-01-18T06:10:15 < mawk> ah
2019-01-18T06:13:14 < Cracki> "remaining = fread"...
2019-01-18T06:13:58 < dongs> sofar cracki is the closest to right answer :d
2019-01-18T06:14:04 < Cracki> maybe a different name for "the number of items read or written" would cause less confusion
2019-01-18T06:14:22 < Cracki> what's TS, mpeg transport stream?
2019-01-18T06:14:25 < dongs> yeah
2019-01-18T06:14:30 < Cracki> interesting!
2019-01-18T06:15:00 < Cracki> oh, not even sockets, so a read should return the full requested size (unless end)
2019-01-18T06:15:08 < dongs> sure thing
2019-01-18T06:16:19 < Cracki> my brain's spent, I've messed with f32 to ascii decimal the past two days. not too difficult, but... the lesson (reinforced) is to always write down and work through all the reasoning
2019-01-18T06:16:41 < Cracki> I meant to say, there are zero comments
2019-01-18T06:16:46 < dongs> anyway the fix is remaining += fread()
2019-01-18T06:16:57 < dongs> because when you move the tail, there's remaining bytes
2019-01-18T06:17:07 < Cracki> sounds plausible
2019-01-18T06:17:10 < dongs> and you read ts_read_size - remaining
2019-01-18T06:17:28 < dongs> which makes the read buffer smaller and smaller over each loop
2019-01-18T06:17:36 < Cracki> but then you have transfer += remaining as well, which would cause transfer to grow quadratically or something
2019-01-18T06:17:51 < dongs> yeah, total transfer is wrong.
2019-01-18T06:17:54 < dongs> thats actually just debug
2019-01-18T06:17:57 < dongs> i shodul remove it, nothing uses it
2019-01-18T06:18:07 < dongs> i was trying to figure out why it would start shitting out after like 2nd loop iteration
2019-01-18T06:18:42 < Cracki> ah, now I see the pattern. read a block, parse out as many frames as possible, loop
2019-01-18T06:19:45 < Cracki> suggested abstraction: ring buffer struct and functions to work on it
2019-01-18T06:20:49 < Cracki> I see why the memmove helps. no need to wrap around in logic to read a packet.
2019-01-18T06:20:59 < dongs> yes
2019-01-18T06:21:09 < dongs> and it checks sync on each
2019-01-18T06:21:55 < Cracki> IsSynced looks for that 0x47/'G' byte or something, eh?
2019-01-18T06:22:33 < dongs> yes, and other bytes in header and makes sure continuity counter is legit
2019-01-18T06:23:24 < dongs> this is TLV in ts so header is always 47 00 01 0X where X is cc
2019-01-18T06:23:35 < Cracki> so... you're parsing a transport stream, which you got out of some device via shiftregistering and bodgewiring
2019-01-18T06:23:59 < dongs> yeah
2019-01-18T06:24:14 < Cracki> btw, https://pbs.twimg.com/media/DxGTddNV4AAOqMy.jpg

2019-01-18T06:27:38 < dongs> i always miss th e shit
2019-01-18T06:27:43 < dongs> last launch was like morning or day time or something
2019-01-18T06:27:48 < dongs> i thought i saw something but wasnt sure
2019-01-18T06:27:54 < Thorn> I was asleep
2019-01-18T06:27:55 < Cracki> spacex should do synchronized booter landings again. that rocked even though they weren't really meant to synchronize
2019-01-18T06:27:55 < dongs> in evening like that it would have been clear for sure
2019-01-18T06:28:24 < Cracki> skip to 11 minutes
2019-01-18T06:29:03 < Thorn> spacex is planning 2 falcon heavy flights ~soon
2019-01-18T06:29:10 < Cracki> launch near 35 mins
2019-01-18T06:29:35 < Cracki> >we have a go for pyrotechnics arming
2019-01-18T06:29:36 < dongs> oh wait
2019-01-18T06:29:38 < dongs> it was live 4 hours ago
2019-01-18T06:29:41 < dongs> so during day
2019-01-18T06:29:42 < Cracki> pyrotechnics my sides
2019-01-18T06:29:43 < dongs> i wouldnt have seen

2019-01-18T06:33:58 < Thorn> or 14.5h, 1905UTC
2019-01-18T06:34:21 < Thorn> no that's jan 19
2019-01-18T06:34:30 < Thorn> so tomorrow
2019-01-18T06:35:08 < Cracki> they got one NRO sat up at least that I remember... but with some paranoid requirements such as fuck the booster and nobody gets to see shit
2019-01-18T06:35:28 < Cracki> for that other thing recently, I understand they needed all the fuel to get it up there...

2019-01-18T10:35:00 < R2COM> no dongs i dont use altium. its funny you asked me this now...because today when i was leaving work, on the way home i got call from Altium representative who wanted to sell it to me
2019-01-18T10:35:06 < R2COM> lol 
2019-01-18T10:35:17 < dongs> sure sure
2019-01-18T10:35:21 < dongs> what garbage do you use then?
2019-01-18T10:35:23 < dongs> orcad?
2019-01-18T10:35:24 < R2COM> im serious
2019-01-18T10:35:26 < R2COM> yes
2019-01-18T10:35:29 < dongs> do they have a version that uses modern GPUs?
2019-01-18T10:35:33 < R2COM> at work i use allegro
2019-01-18T10:35:37 < dongs> or do tehy still draw with like GDI
2019-01-18T10:35:44 < dongs> and have a menu item to "redraw screen"
2019-01-18T10:35:51 < dongs> because its hard to keep state and shit gets unsyned sometimes
2019-01-18T10:36:10 < R2COM> i dont think they use GPU...but honestly i dont think its required...nothing heavy to process there
2019-01-18T10:36:13 < dongs> last i used pirated copy of cuckcad, there was a view->refresh everythign (or somethin) menu item
2019-01-18T10:36:17  * Haohmaru XOR blends dongs repeatedly
2019-01-18T10:37:09 < R2COM> you dont need to use gpu really for that shit
2019-01-18T10:37:43 < R2COM> i dont like cadence IC design software its a horrible shit, but PCB stuff is ok
2019-01-18T10:37:58 < dongs> its a horrible shit cuz it runs on lunix
2019-01-18T10:38:00 < dongs> you know that already.
2019-01-18T10:38:22 < R2COM> its worse, i have to use some client (ExceedOnDemand) to connect to server
2019-01-18T10:38:32 < R2COM> and that EOD stuff runs on top of my Win10 
2019-01-18T10:38:36 < R2COM> at work
2019-01-18T10:38:45 < dongs> eyah thats lunix . its an Xserver or hwatever
2019-01-18T10:38:47 < dongs> garbage.
2019-01-18T10:38:57 < R2COM> so on top of linux shit i also have server delays and lags + slowness of cadence soft
2019-01-18T10:39:40 < R2COM> those bastards dont improve IC software
2019-01-18T10:39:43 < R2COM> cuz noone is pushing
2019-01-18T10:39:49 < R2COM> they literally have monopoly on it
2019-01-18T10:39:54 < R2COM> so they dont have to work hard on this
2019-01-18T10:40:06 < R2COM> PCB on the other hand is different, lots of companies to choose from
2019-01-18T10:40:09 < dongs> with $500k per license they don't have to work hard at all
2019-01-18T10:40:15 < R2COM> so they keep their orcad PCB suite well working
2019-01-18T10:40:29 < dongs> i dont think it works well
2019-01-18T10:40:35 < dongs> its unintuitive and shitty 
2019-01-18T10:40:38 < R2COM> lol its more than $500k for us for all the packages we got
2019-01-18T10:40:58 < R2COM> and each license costs more
2019-01-18T10:41:05 < R2COM> for example there are 100 slots for simulator
2019-01-18T10:41:10 < R2COM> only 100 people then can use
2019-01-18T10:41:11 < R2COM> etc
2019-01-18T10:41:17 < R2COM> every slot = $$$
2019-01-18T10:41:37 < R2COM> its totally jewish company
2019-01-18T10:43:15 < R2COM> there is nothing better than cadence for PCB now
2019-01-18T10:43:24 < R2COM> and im not going to spend time now on learning new PCB soft
2019-01-18T10:43:48 < R2COM> even more  - paying for new soft
2019-01-18T10:45:49 < Haohmaru> leenookz
2019-01-18T10:46:01 < dongs> < R2COM> there is nothing better than cadence for PCB now

2019-01-18T10:46:30 < dongs> its so much better theres no comparison
2019-01-18T10:46:32 < Haohmaru> wasn't altium a "disaster" ? ;P~
2019-01-18T10:46:37 < R2COM> unfortunately not. too many actions and dialogs and shit to just export parts into layout
2019-01-18T10:46:38 < R2COM> etc
2019-01-18T10:46:40 < dongs> yes, but orcad is disaster x 100
2019-01-18T10:46:44 < R2COM> all actions are multiple steps
2019-01-18T10:47:05 < R2COM> and biggest thing is, altium routing sucks really bad
2019-01-18T10:47:24 < R2COM> if area is congested you have to manual route every fucking mil your route
2019-01-18T10:47:32 < dongs> isnt routing something you should be good at, not pcb soft
2019-01-18T10:47:34 < R2COM> whereas routing in cadence is very intuitive
2019-01-18T10:47:39 < R2COM> and flexibnle options
2019-01-18T10:47:45 < R2COM> no
2019-01-18T10:47:52 < R2COM> pcb soft needs to be intuitive
2019-01-18T10:47:56 < dongs> it is
2019-01-18T10:47:58 < dongs> altium that is
2019-01-18T10:47:59 < R2COM> no
2019-01-18T10:48:00 < dongs> orcad isnt
2019-01-18T10:48:06 < R2COM> uh
2019-01-18T10:48:09 < R2COM> i used both
2019-01-18T10:48:20 < Haohmaru> it intuitively makes ugly track turns? ;P~
2019-01-18T10:48:21 < R2COM> altium is not good routing
2019-01-18T10:48:39 < dongs> altium is great routing
2019-01-18T10:48:41 < R2COM> intuitive = figure out relatively proper route among obstacles
2019-01-18T10:48:44 < dongs> single route, multiroute, etc.
2019-01-18T10:49:02 < R2COM> enjoy your chinese soft
2019-01-18T10:49:05 < Haohmaru> ah, sorta like kicad's push&shove router
2019-01-18T10:49:15 < dongs> where doyou think they stole it from
2019-01-18T10:49:23 < R2COM> from some old compa y
2019-01-18T10:49:25 < R2COM> foprghot name
2019-01-18T10:49:26 < dongs> its straight copy from altium
2019-01-18T10:49:37 < R2COM> i mean altium was built on..protel;?
2019-01-18T10:49:38 < R2COM> whatever
2019-01-18T10:49:40 < Haohmaru> i thought cern wrote it
2019-01-18T10:50:02 < R2COM> is kicad advanced nowadays?
2019-01-18T10:50:08 < R2COM> i havent touched it for ages
2019-01-18T10:50:16 < Haohmaru> it works for me plenty fine
2019-01-18T10:50:42 < Haohmaru> if it's gud enough for making computer motherboards and single board computers - i guess it's not too bad
2019-01-18T10:50:47 < R2COM> length matching and differential route?
2019-01-18T10:51:06 < R2COM> not sure if any PC motherboard manufacturer uses kicad lol
2019-01-18T10:51:26 < Haohmaru> no, some folks who use kicad have made such things
2019-01-18T10:51:52 < R2COM> just buy PC soft which you like and stop raging dongs
2019-01-18T10:52:01 < R2COM> and if you rage it means your soft sucks and you are unhappy 
2019-01-18T10:52:13 < Haohmaru> there's differential pair routing, length and skew matching, but i don't know if it currently takes vias into account
2019-01-18T10:53:02 < Haohmaru> i'm only using the stable versions, there's more new things in the dev version
2019-01-18T10:53:30 < R2COM> there you go dongs, switch to kicad
2019-01-18T10:53:35 < Haohmaru> oh noes

2019-01-18T10:55:02 < dongs> like star shittyzen
2019-01-18T10:55:06 < dongs> except its acutally out
2019-01-18T10:55:18 < R2COM> its cool sim
2019-01-18T10:55:24 < R2COM> btw dongs it supports VR

2019-01-18T10:57:14 < dongs> haha
2019-01-18T10:57:44 < Haohmaru> uh, so what can you do with that ship?

2019-01-18T10:58:05 < R2COM> but there is no full universe and game is far from ready

2019-01-18T11:51:51 < day> Haohmaru: i dont think it takes vias into account for length matching because i dont think kicad knows the pcb thickness, does it?
2019-01-18T11:52:08 < Haohmaru> yeah
2019-01-18T11:52:22 < Haohmaru> not in the stable version at least
2019-01-18T11:53:49 < day> would be rather difficult to use i think. pcb core thickness, layer thickness, isolator thickness etc.
2019-01-18T11:53:52 < Haohmaru> but i read some sort of guide on pcb layout that says that if one highspeed signal has to go thru a via - the others (which are related to it) should too
2019-01-18T11:54:41 < day> yeah when you route dif wires and hit the via button it will via both automatically, thats what i always did so far
2019-01-18T11:54:56 < day> wires/traces
2019-01-18T11:55:05 < Haohmaru> tracks ;P~
2019-01-18T11:55:18 < day> :P
2019-01-18T11:57:01 < Haohmaru> i recently made an spdif thing with digital audio interfance, and it worked fine
2019-01-18T11:57:32 < Haohmaru> it's not differential, so i routed the tracks manually, and then adjusted their lengths individually so they match
2019-01-18T11:58:17 < Haohmaru> but i guess that's not very high-speed
2019-01-18T12:02:08 < karlp> I'm surprised you even bothered for that
2019-01-18T12:03:26 < Haohmaru> it's easy, so i'd rather do it than end up with 5 non-working PCBs
2019-01-18T12:04:36 < Haohmaru> i calculated that at the highest sampling rate i wanted to support, the audio clock would be a bunch of MHz
2019-01-18T12:05:06 < Haohmaru> iirc it waz something like 19200*2*32
2019-01-18T12:06:08 < Haohmaru> oops, forgot one zero
2019-01-18T12:15:44 < rajkosto> its like a couple of mhz max
2019-01-18T12:15:55 < rajkosto> and spdif is a single wire anyway ?

2019-01-18T12:20:29 < Haohmaru> rajkosto i meant on the other side of the interface, there are like 3 or so signals

2019-01-18T13:17:27 < jpa-> Ecco: i assumed it does nothing (high-Z), but atleast on STM32F030 it enables the internal pull-down resistor (which is of course also mentioned in reference manual)
2019-01-18T13:17:50 < jpa-> though that is only in standby mode, in stop and higher power states the pins keep their previous configured state
2019-01-18T13:23:41 < zyp> now that it's light outside, I snapped a couple photos of my internet connection: https://bin.jvnv.net/file/IdQue.jpg https://bin.jvnv.net/file/Ve6Gy.jpg
2019-01-18T13:24:17 < zyp> (my pal that I'm borrowing from lives up in 88B on the right side of the photo)
2019-01-18T13:24:19 < jpa-> does your neighbour know you're stealing his bits?
2019-01-18T13:25:26 < zyp> it'd be pretty hard to put up the antenna on his end, run the cable inside and plug it in without his knowledge
2019-01-18T13:26:16 < zyp> if you zoom into the pic, you'll see the remote antenna mounted on the railings on the stair
2019-01-18T13:26:19 < englishman> no snow even in january
2019-01-18T13:26:52 < zyp> we got the first snow for this year the other day, but it all rained away yesterday
2019-01-18T13:27:34 < englishman> you wont get to use that nice ice dam
2019-01-18T13:27:38 < jpa-> we have ~50cm here
2019-01-18T13:28:58 < englishman> about the same here https://i.imgur.com/Keaz4XE.jpg
2019-01-18T13:29:47 < zyp> I'm happy I don't need to deal with snow while moving
2019-01-18T13:29:48 < jpa-> you have no buildings :|
2019-01-18T13:30:25 < zyp> doing this sort of stuff would be kinda inconvenient in the middle of a snow storm: https://bin.jvnv.net/file/AlHVM.jpg
2019-01-18T13:32:20 < qyx> woo englishland
2019-01-18T13:32:47 < PeterM> zyp how weatherproof are those outdoor units? they look pretty... indoorsy
2019-01-18T13:33:18 < zyp> https://www.ui.com/airmax/litebeam-ac-gen2/
2019-01-18T13:33:32 < qyx> ui == ubiquit?
2019-01-18T13:33:33 < zyp> not sure what part of that looks indoorsy
2019-01-18T13:33:37 < zyp> apparently
2019-01-18T13:33:44 < zyp> haven't seen that domain before
2019-01-18T13:33:52 < qyx> pretty cool domain
2019-01-18T13:34:54 < zyp> apparently this shit is meant for 5-15km, I don't see how you're gonna manage that indoors
2019-01-18T13:35:31 < PeterM> zyp all the small holes and crevices on the case makes it look pretty indoorsy, im not sure how well its sealed because i havent seen one in real life before, but i personally would confuse that for a unit that is to be mounted indoors, behind a window or something
2019-01-18T13:35:37 < zyp> my link is like 65m, and the devices complain about rx power being too high even though I set tx power to minimum
2019-01-18T13:35:53 < PeterM> if you hadnt mentiopned it
2019-01-18T13:36:46 < zyp> it's all passive mechanical parts, apart from the center thing which is a single enclosed unit
2019-01-18T13:37:04 < PeterM> yeah, i jsut saw that in the little exploded view thing on the website
2019-01-18T13:37:11 < PeterM> i wouldnt have known that from your photo
2019-01-18T13:37:11 < zyp> only opening is for the ethernet cable entry in the back, which is designed so that water doesn't run in, while letting moisture out
2019-01-18T13:37:23 < zyp> i.e. typical design for outdoor stuff
2019-01-18T13:37:54 < englishman> the holes in the reflector are probably to keep it light, so when the wind blows it off it won't break a windshield
2019-01-18T13:39:43 < zyp> yeah
2019-01-18T13:40:33 < PeterM> yeah, it makes sense looking at the website
2019-01-18T13:41:06 < zyp> cute hardware either way
2019-01-18T13:41:41 < zyp> once I get the fiber installed, I guess I'll play around with some longer shots to test performance/range
2019-01-18T13:43:31 < zyp> oh well, time to get some more stuff moved
2019-01-18T13:47:04 < PeterM> wow, they are pretty cheap zyp
2019-01-18T13:47:13 < dongs> AIR MAX
2019-01-18T13:47:13 < dongs> sup
2019-01-18T13:47:21 < PeterM> if you do get around to long range testing, tell us how it goes
2019-01-18T13:47:29 < PeterM> g'dongs
2019-01-18T13:49:55 < dongs> PeterM: https://mikrotik.com/product/wireless_wire_dish
2019-01-18T13:50:11 < dongs> o wait, i missed what are you trying to do?
2019-01-18T13:50:59 < PeterM> im not doing shit, just curious
2019-01-18T13:51:06 < dongs> ah
2019-01-18T13:51:16 < dongs> ive got a nice network of mikodiks around my place
2019-01-18T13:51:54 < day> mikrodicks*
2019-01-18T13:53:13 < PeterM> also im not keen on mikrodik, ive opened some of their stuff before and seen parts not up to spec  (like something says 12-24v input and the input goes striahgt into a buck converter than maxes out at 23v...)
2019-01-18T13:53:42 < Laurenceb> GAMMON
2019-01-18T13:53:53 < dongs> PeterM: eh, maybe but their shit works for me
2019-01-18T13:54:10 < dongs> i have their SXT and mANT shit up outside and they lived through typhoons and garbage jap weather
2019-01-18T13:54:23 < dongs> by the time you're over 100+meters of cat5, that 24V from PoE is gonna be a lot less
2019-01-18T13:56:13 < englishman> i'm kinda torn, mikrodik has that underdog feeling, but just navigating their catalogue of over9000 parts is frustrating, i cant imagine what their shitty BeOS based os would be like, ubnt looks friendly and inviting
2019-01-18T13:57:27 < PeterM> dongs fair enough, i think it was on one of their older lines of routers and switches - probably stopped doing that shit when  i sent them an email about it...
2019-01-18T13:57:43 < PeterM> englishman i agree 100%
2019-01-18T13:58:02 < dongs> i dont really give a shit waht garbage OS the shit runs
2019-01-18T13:58:06 < dongs> i've had to deal with it a total of: 0 times
2019-01-18T13:58:13 < dongs> i turn it on, click CPE/AP in gui, and done
2019-01-18T13:58:40 < PeterM> noice
2019-01-18T13:59:54 < dongs> and i donno hwo ubnt shit works but
2019-01-18T13:59:58 < dongs> with mikrodik winbox
2019-01-18T14:00:07 < dongs> i can see ALL my shit despite it being on different networks and shit
2019-01-18T14:00:23 < dongs> it sees my fiber/gbe switch, all the wireless shit even at remote locations etc.
2019-01-18T14:00:41 < dongs> so i can fuck with it all from one place
2019-01-18T14:01:18 < PeterM> who writes this shit though; "Fiber speed and quality on distances up to 1500 m" "offering a stable and fast link for distances of 1500 meters or more."  - is it less than 1500m, 1500m or mroe than 1500m?
2019-01-18T14:01:39 < dongs> i dont expect it to work > 1.5km
2019-01-18T14:01:47 < dongs> but its not for that purpose either.
2019-01-18T14:01:55 < qyx> mikrotik is not beosof course
2019-01-18T14:02:04 < dongs> pretty sure he was joking
2019-01-18T14:02:11 < qyx> uh, missed that part
2019-01-18T14:02:26 < dongs> its ReeeeeeeeOS
2019-01-18T14:03:12 < PeterM> sure, i bet it isn't (meant to work >1.5km) but they could be clear in their own material on the site.
2019-01-18T14:03:37 < qyx> using mikrotiks from ~2005 and I can say they work
2019-01-18T14:03:43 < PeterM> and im sure their products are fine, i mean, they're still in bussiness so people must still buy their parts
2019-01-18T14:03:57 < englishman> god damn every time i go to that site, fucking rage
2019-01-18T14:04:14 < englishman> wAP ac or hAP ac?
2019-01-18T14:04:19 < englishman> better not tell me what the difference is
2019-01-18T14:04:46 < qyx> idk, for some time the names were logical
2019-01-18T14:04:48 < englishman> or what the hAP ac 2 does different, or why the non-2 model is still sold
2019-01-18T14:05:06 < englishman> maybe i should check out the hAP ac lite TC ? or just get the ubnt on amazon
2019-01-18T14:05:31 < englishman> page closed, fuck mikrodik

2019-01-18T16:12:44 < day> not all eu passports are equal
2019-01-18T16:13:01 < day> germans dont need a visa for turkey, but im pretty sure most other eu countries need one
2019-01-18T16:20:44 < Steffanx> Like you want to go to turkey..
2019-01-18T16:20:52 < BrainDamage> I went to turkey with just my ID card like about 8 years ago
2019-01-18T16:20:52 < Steffanx> Have fun with the erdo.
2019-01-18T16:21:25 < Steffanx> Makes me wonder if we have turkish ##stm32ers
2019-01-18T16:23:12 < PaulFertser> I had a dream reading Fleck was originally from the Ukraine, no fucking idea how that could make sense.
2019-01-18T16:23:27  * karlp loved turkey last time, but that was pre erdo
2019-01-18T16:23:38 < Steffanx> Hm interesting dream PaulFertser 
2019-01-18T16:24:01 < PaulFertser> Do you dream of ##stm32 convos Steffanx ?
2019-01-18T16:27:06 < Steffanx> No, not ever PaulFertser
2019-01-18T16:27:21 < Steffanx> Or perhaps i do, but i dont remember

2019-01-18T16:47:46 < day> it's probably not a unique thing to german, but it definitely doesnt work for all eu citizens, as the wiki visa requirement link from dongs shows. some even need visas.
2019-01-18T16:48:20 < BrainDamage> not particularly, but I think my country tends to have good diplomatic relationships with most
2019-01-18T16:48:34 < BrainDamage> it's one of the countries with least visa requirements in absolute

2019-01-18T18:46:40 < dongs> best answer
2019-01-18T18:47:25 < kakimir> how much you pay your chinagirl per month?
2019-01-18T18:47:35 < kakimir> or how does the arrangement work exactly?
2019-01-18T18:47:36 < aandrew> yeah it's crazy improtant to have a few good people on the ground in .cn or it's just an uphill struggle every day
2019-01-18T18:47:50 < aandrew> wowwee had an entire .hk office dedicated to that shit
2019-01-18T18:47:54 < aandrew> has*
2019-01-18T18:48:17 < aandrew> I'm sure they have some people in shenzhen as well, IIRC one would come into the .hk office a few days a week/few weeks
2019-01-18T18:49:47 < aandrew> yep this PSRAM emulation will work good for FMC I think
2019-01-18T18:50:09 < aandrew> STM32 DMA from FMC memory space to SRAM, FPGA diddles the WAIT# line as needed. easy peasy
2019-01-18T18:50:18 < paul_99> keil doesn't work with my chip, no idea why, 3 others on their forums with the same problem
2019-01-18T18:50:20 < dongs> kakimir: i buy stuff and she gets a bit of kickback
2019-01-18T18:50:34 < dongs> sometimes i treat her to stuff if we do pretty good biz
2019-01-18T18:50:41 < paul_99> problem I am having is that their gdb server is not loading the flash image
2019-01-18T18:50:54 < dongs> paul_99: wat chip is it
2019-01-18T18:50:57 < aandrew> dongs: so basically you ask her to find <description> and she comes back with a list, you select and buy from her for price+markup?
2019-01-18T18:51:00 < paul_99> debugging doesn't work, its all fine if I preload the image with ST Utility
2019-01-18T18:51:03 < paul_99> BLUENRG-2
2019-01-18T18:51:07 < dongs> oh that shit lol
2019-01-18T18:51:08 < paul_99> the bluetooth one
2019-01-18T18:51:37 < paul_99> was hoping someone would have TrueSTUDIO and can load a flash image on the command line so I can at least compare to what I'm getting
2019-01-18T18:51:56 < aandrew> paul_99: sorry, I don't do IDEs. they are almost always more trouble than they're worth IME
2019-01-18T18:52:25 < paul_99> yea, well the idea was to at least jsut be able to build and quickly go through the sample projects
2019-01-18T18:52:32 < paul_99> without having to setup each one..
2019-01-18T18:53:00 < paul_99> only supplied for Keil,TrueSTUDIO and IAR
2019-01-18T18:53:41 < dongs> isnt turdstudio free now?
2019-01-18T18:53:44 < paul_99> yea
2019-01-18T18:53:47 < paul_99> STM32 edition
2019-01-18T18:53:52 < paul_99> think STM bought then
2019-01-18T18:53:53 < paul_99> them
2019-01-18T18:54:15 < paul_99> looks like they only changed the branding, and didn't actually test anything on their parts
2019-01-18T18:54:19 < kakimir> dongs: how big slice you give typically of how big deals?
2019-01-18T18:55:20 < dongs> kakimir: i donno, its not decided
2019-01-18T18:56:24 < kakimir> so you have 0 track record with business with her?
2019-01-18T18:56:33 < kakimir> or what do you mean
2019-01-18T18:57:26 < kakimir> or that you just say do this stuff for me and I give you 300rmb
2019-01-18T18:58:49 < dongs> what do you mean? ive been fuckin around with her for like.. hm i dont even remember this shit

2019-01-18T18:58:54 < PaulFertser> kakimir considers being dongs' girl?

2019-01-18T19:13:34 < dongs> GTP is what you use on dicklinx when you wanna do displayport and shit
2019-01-18T19:13:43 < dongs> its some differential shit
2019-01-18T19:15:09 < rajkosto> GTP is for DP, Pci-E, USB3, SATA, etc

2019-01-18T19:22:41 < aandrew> I haven't used transcievers either, my PCIe work used an external PHY becaue the CyIV-GX did not meet spec at -40C

2019-01-18T19:24:31 < tctw> that's nice tho, rajkosto 
2019-01-18T19:24:35 < rajkosto> then its not 4GHz
2019-01-18T19:24:56 < tctw> yes it is
2019-01-18T19:24:58 < rajkosto> 9900k still has moar cores
2019-01-18T19:25:05 < tctw> 4.01GHz base speed, turbo to like 4.4
2019-01-18T19:25:13 < rajkosto> why not 5

2019-01-18T19:25:31 < tctw> I don't watch my CPU specs all the time, can't be sure atm
2019-01-18T19:25:45 < rajkosto> on 8086k you get 5ghz at stock volts
2019-01-18T19:26:02 < tctw> ah, then I might just be wrong
2019-01-18T19:26:20 < rajkosto> you just need to change the multiplier max in bios and enable multi core enhancement

2019-01-18T20:31:17 < rajkosto> where do you lads stash your custom altium libraries
2019-01-18T20:31:41 < rajkosto> i used to put them same place altium put theirs but taht shit gets overwritten on uninstalls/reinstalls
2019-01-18T20:32:09 < zyp> I used to just keep a lib in each project and just copy it over to the next project
2019-01-18T20:32:22 < zyp> but eventually I made a git repo to hold a separate library project
2019-01-18T20:32:40 < zyp> so the answer to your question: in that git repo
2019-01-18T20:32:43 < rajkosto> 1. is what im doing atm
2019-01-18T20:32:48 < rajkosto> i meant on the filesystem
2019-01-18T20:32:51 < zyp> something like ~/Documents/altium_lib/
2019-01-18T20:33:33 < zyp> messing inside altium's folders is just dumb, and you've found out one reason why :p
2019-01-18T20:33:39 < rajkosto> can i have example of effective comment/description before i make a fuckton of resistors
2019-01-18T20:34:00 < zyp> why make a fuckton? just make one
2019-01-18T20:34:27 < zyp> I mean, people are split on that, but IMO it makes more sense to just have one resistor part with a Value parameter
2019-01-18T20:34:46 < rajkosto> value doesnt pass to pcb
2019-01-18T20:34:52 < zyp> I think my comment on the part is something like =Value
2019-01-18T20:34:52 < rajkosto> so you have to edit the comment/descrtiption every time you update value
2019-01-18T20:34:57 < zyp> sure it does
2019-01-18T20:35:29 < rajkosto> i like to have a fake-BOM by looking at the pcb list
2019-01-18T20:36:10 < zyp> I'd pull it up and snap some screenshots for you, but my desktop computer is in the middle of being moved, so it's sitting disconnected in a corner
2019-01-18T20:37:01 < rajkosto> what is this "=Value" thing
2019-01-18T20:37:09 < rajkosto> comment is most prominently visible in pcb view
2019-01-18T20:37:34 < rajkosto> so i would put stuff like SMD Resistor 0603 =Value 1% ?
2019-01-18T20:37:51 < rajkosto> and the =Value would automatically pass from set value in schematic ?

2019-01-18T20:38:39 < rajkosto> i dont want to have to have to edit the value twice, one not being visible in schematic, and one not being visible in pcb
2019-01-18T20:38:46 < rajkosto> good mistake fodder
2019-01-18T20:38:46 < Steffanx> Almost the same thing was discussed on 23-december 2018
2019-01-18T20:39:36 < Steffanx> and it seems you were involved in this converstation.
2019-01-18T20:39:46 < rajkosto> and i didnt get proper answer
2019-01-18T20:40:07 < Cracki> wat semen injection
2019-01-18T20:40:18 < Cracki> and they seriously did lit research on that
2019-01-18T20:40:27 < Cracki> *review
2019-01-18T20:40:29 < rajkosto> googling for Altium "=Value" gives me nothin
2019-01-18T20:40:59 < Cracki> that altium "feature" seems to either require very new versions, or it's a myth
2019-01-18T20:41:09 < mawk> intraveinous injection sorry, not subcunaeous
2019-01-18T20:41:13 < mawk> I don't know if that's worse
2019-01-18T20:41:18 < Cracki> what you wanna "google" for is documentation on some kind of string interpolation or variables
2019-01-18T20:41:40 < Cracki> it was subcutaneous, not iv
2019-01-18T20:41:42 < Steffanx> rajkosto, it was semi answered
2019-01-18T20:41:46 < Cracki> iv wouldn't have caused an abscess
2019-01-18T20:41:52 < rajkosto> yes and since then ive been manually updating Comment and Description
2019-01-18T20:41:52 < mawk> bad iv does
2019-01-18T20:41:55 < Steffanx> and the conclusion was this is ufly: https://electronics.stackexchange.com/questions/369454/can-i-combine-comment-field-from-other-parameters-in-altium-designer
2019-01-18T20:41:56 < mawk> if you miss the vein
2019-01-18T20:42:01 < Steffanx> ugly
2019-01-18T20:42:04 < Cracki> then it's not iv, but beside the vein
2019-01-18T20:42:07 < rajkosto> but now i see this =Value thing
2019-01-18T20:42:21 < mawk> I guess he mainly did iv but sometimes missed the vein and went subcutaneous
2019-01-18T20:42:30 < mawk> also he seemed to have put bubbles in here
2019-01-18T20:42:47 < Cracki> oh heck they do say he tied i.v.
2019-01-18T20:43:09 < Cracki> bubbles in veins are verrry good
2019-01-18T20:45:40 < rajkosto> also i suppose you can have one schematic symbol for all the resistors and then choose 0603 or 0402 as the footprint but this like NEVER works out
2019-01-18T20:46:01 < Cracki> such incidents are always because they're perverts and they always come with an "innocent" excuse
2019-01-18T20:46:35 < Cracki> circuit design needs to be rethought
2019-01-18T20:47:26 < rajkosto> the footprint selection in schematic editor is kinda sucky and doesnt update the pcb properly even if you do the whole "Update Footprint from libraries" thing
2019-01-18T20:52:24 < rajkosto> preference? in value include the unit or not (farads, ohms, henries)
2019-01-18T20:52:53 < zyp> rajkosto, one schematic part for all footprints is what I do, works for me
2019-01-18T20:54:24 < rajkosto> i had troubles even using the altiuum supplied onesa with the "medium, low, high" density settings
2019-01-18T20:54:49 < rajkosto> update footprint in schematic, it doesnt change properly in pcb after changelist

2019-01-18T21:10:13 < specing> Does anyone know how to mix .rodata and .text sections with gcc? Right now there is stuff in .rodata that is accessed by a pointer stored together with the code, but I'd like it to skip that if possible.
2019-01-18T21:16:27 < qyx> you are trying to achieve interesting things
2019-01-18T21:21:24 < mawk> what do you mean skip specing ?
2019-01-18T21:21:34 < mawk> you want less indirection ?
2019-01-18T21:22:24 < mawk> because currently you're using a GOT
2019-01-18T21:38:41 < Steffanx> why the BrainDamage is missing out of the pro stm32 telegram group/
2019-01-18T21:39:17 < Steffanx> i mean, its all blaxter without the laurence
2019-01-18T21:41:31 < Ultrasauce> wait theres a tg group
2019-01-18T21:44:27 < specing> mawk: to skip having to store the whole 4-byte pointer by moving that data into pc-relative range (thumb)
2019-01-18T21:46:58 < mawk> yeah but it's required
2019-01-18T21:47:28 < mawk> if the function is too far away
2019-01-18T21:47:43 < mawk> but it's in a 64 MiB around the position counter, it should be fine
2019-01-18T21:47:53 < mawk> maybe your toolchain enabled this by default
2019-01-18T21:47:57 < mawk> try -mno-long-calls
2019-01-18T21:52:35 < zyp> specing, no matter how many times you ask, you're still not gonna get the compiler to stuff strings into local literal pools :)
2019-01-18T21:53:41 < zyp> plain variables should be doable by declaring them static const
2019-01-18T21:54:47 < zyp> non-static const have to be emitted to .rodata so it's visible to other translation units, but for static const the compiler would discard all symbols it has folded all references to
2019-01-18T21:55:17 < specing> zyp: why not
2019-01-18T21:56:16 < specing> mawk: this is M0, so PC +- 1024 give or take (thumb) and that is why I am asking how to make it emit local constants SO IT WILL NOT BE FAR AWAY
2019-01-18T21:56:36 < zyp> because compilers doesn't do that, AFAIK strings are always emitted to .rodata so that the linker can deduplicate reused literals
2019-01-18T21:56:45 < specing> sorry for yelling, I just want to get this point across
2019-01-18T21:56:50 < mawk> you can alter that behavior zyp 
2019-01-18T21:56:57 < mawk> but you have to be a master in writing linker scripts
2019-01-18T21:57:03 < zyp> sure, you can write your own compiler
2019-01-18T21:57:11 < mawk> but I don't think you can do it in a general way
2019-01-18T21:57:28 < mawk> you'll have to define your own little local pools for every chunk of data&code you want to be close to each other
2019-01-18T21:57:55 < specing> zyp: but the linker can choose to place those constants into a local pool if it can
2019-01-18T21:57:56 < zyp> mawk, using a linker script to move the literals closer won't turn the already compiled references to them into local references
2019-01-18T21:58:03 < zyp> specing, no, it can't
2019-01-18T21:58:06 < specing> Now the question is how to make it do so
2019-01-18T21:58:18 < mawk> you can choose inside the .c where you put the litterals
2019-01-18T21:58:19 < zyp> constant pools are generated by the compiler, not the linker
2019-01-18T21:58:33 < mawk> using __attribute__((__section__("something"))) attributes
2019-01-18T21:58:37 < zyp> by the time the linker sees this, they are already part of the function
2019-01-18T21:59:38 < zyp> mawk, I'm pretty sure anything that's in another section will get full pointer references, even though the linker might still later locate that other section within a 1024B offset
2019-01-18T22:00:04 < zyp> because the compiler doesn't know where the linker will put it, and thus have to be on the safe side
2019-01-18T22:00:10 < mawk> yeah
2019-01-18T22:00:17 < mawk> yeah, that makes sense
2019-01-18T22:01:29 < mawk> you can always do it in the code section using something like __asm__("mystr:\n\tasciz \"something\""); but that's not something very pretty
2019-01-18T22:02:03 < mawk> but even when you do that I don't know if the compiler won't make a full pointer ref when you reference the label
2019-01-18T22:02:16 < zyp> I know on some platforms, the linker has the ability to insert thunks for function calls
2019-01-18T22:03:26 < zyp> i.e. when the call instruction takes multiple data widths, the compiler emits the smallest one by default, and when the called function is too far away, the linker adds a thunk which is essentially just a small piece of code that loads the full address of the actual function and jumps to it
2019-01-18T22:04:07 < mawk> sounds like the PLT
2019-01-18T22:04:08 < zyp> but I'm not aware of a similar mechanism for data, and I don't think this applies to cortex-m anyway
2019-01-18T22:04:20 < zyp> no, the PLT solves a different problem
2019-01-18T22:07:06 < zyp> the point of a thunk is to be close to where it's called from, so they are spread around in the code, not collected up in a single table
2019-01-18T22:07:11 < mawk> yes

2019-01-18T22:13:09 < mawk> try to put your strings in .code specing 
2019-01-18T22:13:15 < mawk> and if that doesn't work you can give up
2019-01-18T22:13:43 < specing> that is exactly what I'm trying ..
2019-01-18T22:13:49 < mawk> then do it
2019-01-18T22:13:57 < mawk> __attribute__((__section__(".code")))
2019-01-18T22:14:04 < specing> or rather researching, since I don't know how to implement it
2019-01-18T22:15:46 < mawk> I don't know about the subsection names that gcc uses
2019-01-18T22:15:58 < mawk> you can maybe put the string directly inside the function to be sure it's closez
2019-01-18T22:15:59 < mawk> -z
2019-01-18T22:18:37 < Laurenceb_123> this should "just work"
2019-01-18T22:18:53 < Laurenceb_123> you dont need to do AVR style shit on arm
2019-01-18T22:19:45 < zyp> I tried a few tricks here
2019-01-18T22:20:29 < specing> Laurenceb_123: stm32f030 is only like ... 16 KB of code? 
2019-01-18T22:20:38 < zyp> both using the string literal directly, making a static const char array containing the string and using that and doing that inside the function
2019-01-18T22:21:00 < Laurenceb_123> > static const
2019-01-18T22:21:04 < Laurenceb_123> that does it for me
2019-01-18T22:21:06 < zyp> they all result in exactly the same code
2019-01-18T22:21:16 < Laurenceb_123> no __attribute__ shit
2019-01-18T22:21:46 < zyp> only difference is that the plain literal puts the string into .rodata.str1.1, the other two puts stuff directly into .rodata
2019-01-18T22:23:14 < zyp> Laurenceb_123, you're missing the context completely :)
2019-01-18T22:23:25 < Laurenceb_123> ok sorry
2019-01-18T22:23:36 < zyp> Laurenceb_123, but you're also right, shit works, specing is just unhappy about how it works
2019-01-18T22:23:47 < Laurenceb_123> thought it was perman00b question time
2019-01-18T22:24:25 < mawk> you didn't try in .code ?
2019-01-18T22:24:34 < mawk> I don't know any ARM assembly so I can't try
2019-01-18T22:24:43 < zyp> there isn't a section named .code, it's .text
2019-01-18T22:24:57 < mawk> ah .text sorry yes
2019-01-18T22:25:05 < zyp> and no, I didn't try, it's not gonna make a difference
2019-01-18T22:25:13 < zyp> I mean, I could
2019-01-18T22:25:29 < mawk> yeah
2019-01-18T22:25:38 < mawk> gcc doesn't know the referenced address is near
2019-01-18T22:25:57 < mawk> do it in assembly if you don't like how it's done specing 
2019-01-18T22:26:45 < zyp> still no difference :)
2019-01-18T22:27:10 < mawk> why not ? if you can put your strings near your code

2019-01-18T22:27:36 < mawk> ah you mean with the section thing
2019-01-18T22:27:39 < zyp> yeah
2019-01-18T22:27:57 < zyp> doing it with inline assembly is a mess
2019-01-18T22:28:04 < mawk> yeah
2019-01-18T22:28:21 < zyp> emitting the string right in the middle of code means you'd have to jump over it, defeating any potential savings immediately :p
2019-01-18T22:28:23 < specing> I'd like it to just work, without modifications to each and every string
2019-01-18T22:28:23 < mawk> because in any you you're gonna have to declare the label, and gcc doesn't know where it is

2019-01-18T22:30:52 < zyp> make footprints from datasheet, use 3d model to verify it looks sane, if 3d model disagrees, recheck datasheet
2019-01-18T22:32:19 < zyp> specing, oh, right, that was your argument
2019-01-18T22:32:50 < rajkosto> i forgot if you could have multiple pads with same designator or if you should make polygons/fills that just ouch it
2019-01-18T22:32:53 < zyp> IIRC the other day I were asking if you were only disassembling unoptimized code, but I didn't have time to stick around to see your answer
2019-01-18T22:33:16 < zyp> rajkosto, multiple pads with same designator is perfectly fine
2019-01-18T22:33:34 < zyp> for connectors with multiple shield pins, I tend to designate them all SH
2019-01-18T22:34:08 < rajkosto> what about mounting pads/holes that arent actually connected to each other

2019-01-18T22:34:41 < rajkosto> nothing, just structurally there
2019-01-18T22:34:48 < rajkosto> you would usually make them GND so they dont rip off
2019-01-18T22:35:01 < zyp> well, yeah, that's SH in my book :p
2019-01-18T22:35:15 < rajkosto> but they could  be anything, and if you make them all the same
2019-01-18T22:35:28 < rajkosto> then you cant 2 different tracks through 2 different ones
2019-01-18T22:35:33 < Getty> stupid question, someone ever saw some power splitter where you have like 2 outputs and a switch to switch between them? like that never both are connected just one depending on where the switch is?

2019-01-18T22:40:33 < specing> What would be cool would be smarter dishwashers/laundry machines that can talk to eachother and not run high power consumers at the same time
2019-01-18T22:40:57 < specing> so you could have a 3kW residential connection instead of 7kW and pay 8 eur less per month

2019-01-18T22:43:18 < superbia> it's called smart home, prevent both from working at once
2019-01-18T22:43:35 < zyp> I actually lived in a house with single phase 35A 230V some years back
2019-01-18T22:43:37 < specing> zyp: I have russian gas pipeline to home
2019-01-18T22:43:39 < Ecco> hi :)
2019-01-18T22:43:50 < zyp> when I were a student, renting a room in an old house
2019-01-18T22:43:52 < superbia> specing: u got a drill?
2019-01-18T22:44:12 < specing> superbia: many drills
2019-01-18T22:44:14 < zyp> I remember during the winter we blew the main fuse a bunch of times :p
2019-01-18T22:44:26 < day> switching from 3phases 11kW to one phase 7kW is probably problematic due to the cabling
2019-01-18T22:44:44 < rajkosto> zyp, https://images.sshnuke.net/2019-01-18_21-44-35_tMEJ4vlNh.png for stuff like this better to use fill (like it is here) or another pad
2019-01-18T22:44:54 < Ecco> I'd like to find a DC-DC converter for a test bench. Would take 5V and output 4.2V, very accurately. I don't really care about the unit price since I'll buy like 10. Would you guys have any recommendation?
2019-01-18T22:45:45 < day> 4.2V? is that some kind of standard output voltage I've never heard about?
2019-01-18T22:45:50 < Getty> i really can't find anything remotely relevant on amazon....
2019-01-18T22:45:59 < Ecco> day: no, just faking a fully charged lipo cell
2019-01-18T22:46:01 < zyp> day, lipo fully charged, I guess
2019-01-18T22:46:04 < day> ah
2019-01-18T22:46:05 < Ecco> zyp's good
2019-01-18T22:46:07 < zyp> :)
2019-01-18T22:46:09 < Ecco> :-)
2019-01-18T22:46:23 < Ecco> Could as well be 4.1, or even 4 actually
2019-01-18T22:46:34 < zyp> depends on the charge profile
2019-01-18T22:46:35 < day> yeah. dont see the reason for it to be accurate
2019-01-18T22:46:52 < superbia> bedtime
2019-01-18T22:46:55 < Ecco> day: to calibrate other devices
2019-01-18T22:47:07 < day> in that case you probably also want massive current output capability?
2019-01-18T22:47:15 -!- superbia [~superbia@unaffiliated/superbia] has left ##stm32 ["WeeChat 2.3"]
2019-01-18T22:47:24 < Ecco> massive I don't know, less that 1A
2019-01-18T22:47:33 < zyp> why 5V in? why not a normal benchtop supply?
2019-01-18T22:47:33 < Ecco> (not sure that qualifies as massive)
2019-01-18T22:47:50 < Ecco> zyp: because 5V PSU are available everywhere?
2019-01-18T22:47:56 < day> i thought you might want to simulate peak output with like 20A or so 
2019-01-18T22:48:01 < Ecco> oh no
2019-01-18T22:49:02 < zyp> Ecco, if you want an accurate supply for calibration, you probably don't want to rely on random 5V supplies
2019-01-18T22:49:18 < day> my hack solution would be a linear regulator powered by a 5V charger 
2019-01-18T22:49:22 < zyp> I mean, you know that by design, usb chargers drop the voltage when you increase the current draw?
2019-01-18T22:49:40 < Ecco> zyp: I didn't know it was "by design"
2019-01-18T22:49:55 < day> they dont maintain 5V at the rated output current?
2019-01-18T22:50:23 < Ecco> day: yeah, that's what I had in mind: put an LDO behind a 5V charger
2019-01-18T22:50:25 < zyp> no, this is how chargers signal current capacity
2019-01-18T22:50:53 < Ecco> really?
2019-01-18T22:50:58 < day> isnt that done via the resistor network in the charger?
2019-01-18T22:51:03 < Ecco> that's in the USB standard?
2019-01-18T22:51:32 < zyp> when current increases towards the capacity of the charger, voltage decreases towards a reference voltage signalling that the consumer shouldn't draw more
2019-01-18T22:51:41 < day> pretty sure theres a resistor in there that tells the device how much power they can supply (at least pre usb3)
2019-01-18T22:51:43 < Ecco> oh, intersting
2019-01-18T22:52:06 < zyp> IIRC the resistor only says what kind of port it is
2019-01-18T22:52:25 < rajkosto> for the usb charging specification, a "dumb charger" will have a resistor between D+ and D- 
2019-01-18T22:52:30 < rajkosto> indicating how much current it can supply
2019-01-18T22:52:50 < rajkosto> you cant do that if the data lines are actually used
2019-01-18T22:53:11 < day> https://www.instructables.com/id/Modify-a-cheap-USB-charger-to-feed-an-iPod-iPhone/
2019-01-18T22:53:14 < PaulFertser> I've seen samsung phone refusing to draw more than 500mA unless D+/D- (shorted) had specific voltage.
2019-01-18T22:53:39 < day> the device checks voltage levels on the D- D+ lines to determine how much power can be drawn

2019-01-18T23:03:09 < zyp> here's what BC 1.2 says about dedicated chargers: https://bin.jvnv.net/file/B7JDq.png
2019-01-18T23:04:11 < zyp> resistance between data lines is 200 ohms, regardless of current capacity
2019-01-18T23:05:05 < zyp> the purpose of the data lines is only to indicate whether it's a DCP or different type of port
2019-01-18T23:07:44 -!- nicksonT [uid310565@gateway/web/irccloud.com/x-bcburtuofgilvhik] has joined ##stm32
2019-01-18T23:09:01 < day> zyp: DCPs can supply up to 1.5A and are identified by a short between D+ to D-.
2019-01-18T23:09:09 < day> src: https://www.maximintegrated.com/en/app-notes/index.mvp/id/4803
2019-01-18T23:09:23 < zyp> BC 1.2 says 200 ohms
2019-01-18T23:09:52 < zyp> your source are quoting BC 1.1
2019-01-18T23:10:08 < day> i see
2019-01-18T23:10:43 < day> so i take it non DCP ports can do 1A. DCP ports can do more but are a bit more complex
2019-01-18T23:11:36 < zyp> 1.2 CDPs can also do 1.5A
2019-01-18T23:11:44 < zyp> but, yeah
2019-01-18T23:11:53 < zyp> the whole usb charging situation is a mess
2019-01-18T23:12:14 < day> just wait till they add the digital signing stuff ontop
2019-01-18T23:13:15 < zyp> officially, there's USB BC in multiple revisions, USB PD in multiple revisions and the simple signalling in USB type-C
2019-01-18T23:13:36 < zyp> and then there's qualcomm QC in multiple revisions and a bunch of proprietary standards
2019-01-18T23:14:22 < day> i hope oneplus WARP charge is just a fancy marketing name for the same stuff...
2019-01-18T23:15:31 < zyp> type-C has the simplest mechanism, the CC pullup/down that signals whether it's a host or a device has three possible values for host, signalling current capacity; legacy (500mA), 1.5A or 3A
2019-01-18T23:16:06 < zyp> hehe
2019-01-18T23:16:35 < zyp> PD is digital comms
2019-01-18T23:17:24 < zyp> the old revision (pre type-C) does sideband comms over vbus
2019-01-18T23:17:46 < zyp> it got a new revision along with type-C, instead doing sideband comms over the new CC line
2019-01-18T23:18:28 < zyp> I don't think anybody used the old revision for anything useful, but the new one seems to be gaining traction, now that a bunch of laptops can charge from usb-c
2019-01-18T23:24:53 < karlp> paypal wants to charge me $4.30 in fees to transfer $4.30 as a refund to an aliexpress duder
2019-01-18T23:24:56 < karlp> nice one.
2019-01-18T23:25:23 < rajkosto> aliexpress supports paypal now ?
2019-01-18T23:25:33 < malinus> not last I checked (yesterday)
2019-01-18T23:27:33 < karlp> no, seller refunded me because the product handed arrived when ali protection ran out

2019-01-18T23:28:25 < karlp> had some paypal balance I can't use, was hoping to use it.

2019-01-18T23:55:29 < zyp> sounds like pointless hassle, I would have just called the money compensation for stuff not being delivered at the contracted time and kept them :p

2019-01-19T04:59:14 < dongs> rajkosto: the idea there is to always be on grid
2019-01-19T04:59:19 < dongs> i suggest leaving it at 100
2019-01-19T04:59:22 < rajkosto> yes but why cant i change it to imperial
2019-01-19T04:59:27 < dongs> don't
2019-01-19T04:59:36 < rajkosto> it defaults me to mm grid which no symbols ever use
2019-01-19T04:59:42 < dongs> ??? what mm grid
2019-01-19T04:59:47 < rajkosto> best i can do is click the grid icon and change to 2.54mm

2019-01-19T05:02:00 < rajkosto> its in Tools->Document Options
2019-01-19T05:02:08 < dongs> who tehfuck at altinigger thought gray on gray was a good idea
2019-01-19T05:02:11 < rajkosto> https://images.sshnuke.net/2019-01-19_04-02-10_hN83e9uTQ.png
2019-01-19T05:02:17 < rajkosto> it looks like Autodesk 
2019-01-19T05:02:19 < rajkosto> thats why
2019-01-19T05:02:25 < rajkosto> i dont mind it in Max etc
2019-01-19T05:02:47 < rajkosto> the problem with altium is that when you are editing schematics the background is light...
2019-01-19T05:02:54 < rajkosto> with pcb editor its better as the background is dark
2019-01-19T05:02:57 < dongs> > problem
2019-01-19T05:03:10 < dongs> may be for you
2019-01-19T05:03:13 < dongs> but not for normal users
2019-01-19T05:03:21 < rajkosto> i can tolerate
2019-01-19T05:03:27 < rajkosto> 18 was the worst
2019-01-19T05:03:28 < rajkosto> 19 is better
2019-01-19T05:04:08 < karlp> ##stm32, demonstrating daily why altium is the best/worst....
2019-01-19T05:04:22 < rajkosto> the real question is
2019-01-19T05:04:27 < rajkosto> make the schematic ICs have yellow boxes or transparent boxes
2019-01-19T05:04:42 < dongs> yellow transparent
2019-01-19T05:05:03 < dongs> rajkosto: default for altium has always been mils for schematic
2019-01-19T05:05:06 < dongs> ive never seen it in mm
2019-01-19T05:05:09 < dongs> what the fuck did you change
2019-01-19T05:05:14 < aandrew> for schematic always leave your grid at 100. 
2019-01-19T05:05:17 < rajkosto> i told you how i change for schematic
2019-01-19T05:05:24 < rajkosto> but for schematic library i had to just figure it out
2019-01-19T05:05:25 < dongs> aandrew: for some reason, his shit is in millimeters
2019-01-19T05:05:30 < aandrew> yeah he made a change
2019-01-19T05:05:32 < rajkosto> its always in mm for a new schematic libraries
2019-01-19T05:05:32 < aandrew> I did that once
2019-01-19T05:05:33 < dongs> where?
2019-01-19T05:05:35 < aandrew> it's hell to put back
2019-01-19T05:05:48 < dongs> i dont even know where properties for sch library are
2019-01-19T05:05:51 < aandrew> hang on let me see if I can find the shit
2019-01-19T05:05:54 < rajkosto> i actually didnt change anything
2019-01-19T05:05:55 < dongs> since everything is a niggerified sidebar now
2019-01-19T05:05:57 < rajkosto> told 19 not to import anything
2019-01-19T05:06:08 < dongs> i told 19 to import all my shit
2019-01-19T05:06:09 < dongs> from 18
2019-01-19T05:06:10 < dongs> and
2019-01-19T05:06:17 < dongs> it went ahead and ignore the 1st change that i make
2019-01-19T05:06:26 < dongs> which is turning off the faggot unreadable theme
2019-01-19T05:07:23 < dongs> ah
2019-01-19T05:07:24 < dongs> found
2019-01-19T05:07:25 < dongs> rajkosto: 
2019-01-19T05:07:38 < aandrew> hm, prefs -> schematic -> grids, mine are all 10/50/100mil with visible set to 100 for everything
2019-01-19T05:07:45 < dongs> no
2019-01-19T05:07:47 < dongs> thats not here
2019-01-19T05:07:56 < dongs> rajkosto: open schlib
2019-01-19T05:07:58 < aandrew> oh this is 17
2019-01-19T05:07:59 < dongs> click inside any symbol
2019-01-19T05:08:02 < aandrew> not sure what you can do in 19
2019-01-19T05:08:02 < dongs> T, D
2019-01-19T05:08:09 < rajkosto> dongs, you niggerfaggot
2019-01-19T05:08:11 < aandrew> ahh
2019-01-19T05:08:12 < rajkosto> i told you i found that.
2019-01-19T05:08:12 < dongs> then change units to mils on the gay sidebar
2019-01-19T05:08:17 < rajkosto> i even gave you a shot of it
2019-01-19T05:08:21 < dongs> yeah so?
2019-01-19T05:08:23 < dongs> whats hte problem
2019-01-19T05:08:24 < rajkosto> but why is my default for new schlib always mm
2019-01-19T05:08:30 < aandrew> prefs -> schematic -> default units, in there make sure you're using "dxp defaults"
2019-01-19T05:08:31 < dongs> oh probably cuz tyoure some eurofaggot
2019-01-19T05:08:36 < rajkosto> I AM
2019-01-19T05:08:37 < aandrew> that is what I fucked up
2019-01-19T05:08:53 < rajkosto> that doesnt mean altium should be racis
2019-01-19T05:09:03 < dongs> OH!
2019-01-19T05:09:21 < dongs> rajkosto: https://i.imgur.com/akyq6w8.png also here
2019-01-19T05:09:27 < dongs> schematic-.defaults
2019-01-19T05:09:29 < dongs> i bet thats it
2019-01-19T05:09:49 < rajkosto> already in mils there
2019-01-19T05:09:53 < dongs> ok then
2019-01-19T05:09:56 < dongs> i'd say cuz youre eurofag.
2019-01-19T05:09:58 < rajkosto> i think this is for when you make a new thingy
2019-01-19T05:10:05 < rajkosto> not the general schematic editor
2019-01-19T05:10:32 < rajkosto> ill just have to remember to change it each time i make a new sch or schlib
2019-01-19T05:10:38 < dongs> anyway http://worksonmymachine.pro
2019-01-19T05:10:43 < dongs> lemme try make a new schlib
2019-01-19T05:10:47 < dongs> its been literally years since i made a new one
2019-01-19T05:11:02 < rajkosto> it might be doing something dumb like assuming from your windows regional settings
2019-01-19T05:11:22 < dongs> nope,
2019-01-19T05:11:24 < dongs> grid is 100mil
2019-01-19T05:11:26 < dongs> for new lib
2019-01-19T05:11:39 < dongs> i guess y ou just fail it
2019-01-19T05:11:44 < rajkosto> it is for me now too
2019-01-19T05:11:50 < dongs> < rajkosto> it might be doing something dumb like assuming from your windows regional settings
2019-01-19T05:11:54 < dongs> thats my guess
2019-01-19T05:11:54 < dongs> which is why i said
2019-01-19T05:11:56 < dongs> cuz youre eurofag
2019-01-19T05:12:04 < dongs> thats ridiculous tho but whateverf
2019-01-19T05:12:22 < rajkosto> it has always been mm and ive just been changing the grid to 2.54mm lol to get close enoughj\
2019-01-19T05:12:27 < dongs> more than half of altidumb is still writtten in delphi
2019-01-19T05:12:35 < dongs> so the stupid shows
2019-01-19T05:12:57 < PeterM> rajkosto you probably set it to metric/mm when you installed it or in one of the initial configs
2019-01-19T05:13:11 < dongs> well he claimed
2019-01-19T05:13:15 < dongs> he said "not to import" anything
2019-01-19T05:13:17 < dongs> from old
2019-01-19T05:15:13 < rajkosto> you guys ever make the proper usage of input/output/power pins
2019-01-19T05:15:18 < rajkosto> i just leave everything passive cuz dont wanna bother

2019-01-19T05:16:47 < PeterM> depends on the project - for dicking around erc can be a cunt but on bigger stuff yeah i usually set them
2019-01-19T05:16:58 < dongs> sometimes i do
2019-01-19T05:17:04 < dongs> yeah same as peterm
2019-01-19T05:17:18 < dongs> i will usually set shit for interface converting things
2019-01-19T05:17:26 < dongs> just to get those nice arrows in sch
2019-01-19T05:17:32 < rajkosto> arrows are independent tho
2019-01-19T05:17:37 < rajkosto> thats just "Symbols"
2019-01-19T05:17:39 < dongs> you get them if you set type
2019-01-19T05:18:03 < rajkosto> i set the arrows if the manufs symbol has them
2019-01-19T05:18:13 < rajkosto> but never bother with type, as i ignore compiler warnings anyway
2019-01-19T05:19:01 < aandrew> dongs: prefs -> schematic -> default units, in there make sure you're using "dxp defaults"
2019-01-19T05:19:22 < rajkosto> thats not there in 19
2019-01-19T05:19:35 < dongs> aandrew: doesnt exist in 19
2019-01-19T05:19:38 < dongs> ive seen it before
2019-01-19T05:19:50 < rajkosto> i think thats just schematic->General->Units now

2019-01-19T05:20:25 < rajkosto> Schematic->General
2019-01-19T05:20:32 < dongs> doesnt matter cuz i change that depending on what im drawing
2019-01-19T05:20:41 < rajkosto> yes but when you change those
2019-01-19T05:20:43 < rajkosto> the units change
2019-01-19T05:20:47 < rajkosto> if you use A4 it switcehs to mm
2019-01-19T05:21:00 < rajkosto> i switch manually to one of the american ones to get mil
2019-01-19T05:21:08 < dongs> lets see
2019-01-19T05:21:38 < dongs> 'A'
2019-01-19T05:21:48 < dongs> (not A4)
2019-01-19T05:21:54 < rajkosto> k ill never need to switch anymore i dont think
2019-01-19T05:21:56 < rajkosto> will be mil forever
2019-01-19T05:22:02 < dongs> i think if you set it to A, yeah
2019-01-19T05:22:12 < dongs> i neer cahnged that
2019-01-19T05:22:16 < dongs> so unless it kept importing shit
2019-01-19T05:22:17 < rajkosto> (ofc i use mm in pcb editor im not mad)
2019-01-19T05:22:22 < rajkosto> that might be region defaults
2019-01-19T05:23:59 < rajkosto> why is altium 19 randomly doing the IE click sound btw

2019-01-19T09:44:52 < jpa-> apparently enabled by /Wall
2019-01-19T09:44:57 < dongs> yes
2019-01-19T09:45:11 < PeterM> jpa- i sorta understand what you mean, but at the same time, you still need 90% of  the same components, so why not just get a 3c switching converter instead of a 2c mosfet that will do it all for oyu?
2019-01-19T09:45:12 < jpa-> "This option enables all warnings so it can be a bit noisy. Even the VC++ libraries don’t attempt to be clean for all warnings (/Wall)."   eh, crap
2019-01-19T09:46:24 < jpa-> PeterM: if you need voltage control from mcu, a 3c switching converter doesn't do the same
2019-01-19T09:47:15 < jpa-> but yeah, for the simplest cases of just making a constant voltage, there is not much benefit doing it in software
2019-01-19T09:47:22 < PeterM> yes it does, you can just r-c filter pwm  and hook it to the fb node to get whatever target votlage you like
2019-01-19T09:48:02 < PeterM> you can still have the MCU adjust it
2019-01-19T09:48:39 < jpa-> PeterM: hmm; i considered that once but it seemed a bit problematic in the details, like how will the rc-filter affect the stability of the control loop
2019-01-19T09:49:56 < jpa-> but at that point you have atleast 2 extra parts ;)
2019-01-19T09:50:07 < PeterM> if you have a current mode converter that is probably internally compensated, the internal compensation usually makes them quite stable under nearly all conditions at the cost of transient response
2019-01-19T09:50:36 < PeterM> 2 extra parts to place, but they are parts that will already be in the bom
2019-01-19T09:52:15 < jpa-> i think you may be overestimating the trouble of doing it in software, it's just a pwm pin directly to logic-level mosfet, and PI/PID control loop in software
2019-01-19T09:52:52 < dongs> lol
2019-01-19T09:53:00 < jpa-> whereas just figuring out which kind of converters that fb-trick will work with seems like a lot of trouble
2019-01-19T09:56:23 < PeterM> not really, jsut look for "current mode" in the description, and make sure in the example it doesnt have a boat load of rs and cs around the fb pin or comp pin
2019-01-19T09:58:13 < jpa-> what's the benefit, though?

2019-01-19T10:04:35 < PeterM> higher switching frequencies for lower noise or smaller passives, potentially faster loop for better transient response, you can "set and forget" the PWM peripheral, so no need to service a PID loop, if you can use the same part for non-mcu controlled dc-dc to reduce bom items
2019-01-19T10:04:40 < PeterM> theres a fair few
2019-01-19T10:05:20 < jpa-> true enough; depends totally on situation
2019-01-19T10:07:55 < PeterM> yeah, i mean, if you have a powerful mcu or fpga with lots of left overs, and already have a logic level fet in the bom, i dont have a huge issue with it
2019-01-19T10:09:01 < jpa-> i think that rajkosto might have enough trouble implementing either of the options :)
2019-01-19T10:25:20 < PeterM> i mean, if you cant find the inch<-> mm setting on altium, i think you're probably not destined for engineering
2019-01-19T10:25:54 < PeterM> it might be hard, but you're going to have a lot harder challenges later...

2019-01-19T16:44:58 < catphish> i have a gcc linker question - i'm looking to put some uninitialized variables at an arbitrary memory location, but failing completely, how might i do this?
2019-01-19T16:45:46 < catphish> i've successfully set the SECTION for them, but i'm not totally sure how to instruct the linker where to put that section, and also NOT put it in the output (because it's uninitialized)
2019-01-19T16:49:47 < Thorn> something like .section: { . = 0xaddress; KEEP(*(.section*)) } > RAM ?

2019-01-19T17:52:57 < Steffanx> what will it be then specing?
2019-01-19T17:53:03 < rajkosto> just type in 47uh inductor and get 12x12x7 one
2019-01-19T17:53:29 < PeterM> so what good is a 47uh inducctor that could saturate at 1ma?
2019-01-19T17:53:39 < PeterM> because you dont know the spec
2019-01-19T17:53:39 < rajkosto> they are good enough at that size
2019-01-19T17:53:47 < specing> Steffanx: Ada
2019-01-19T17:53:50 < rajkosto> the chinks use them themselves
2019-01-19T17:53:51 < PeterM> good enough for what?
2019-01-19T17:53:56 < rajkosto> dc2dc
2019-01-19T17:54:15 < PeterM> ...
2019-01-19T17:54:23 < rajkosto> current rating comes from the wire thickness
2019-01-19T17:54:30 < rajkosto> and at that size they have thick wire
2019-01-19T17:54:37 < PeterM> bro
2019-01-19T17:54:39 < PeterM> dude
2019-01-19T17:54:41 < PeterM> man
2019-01-19T17:54:43 < PeterM> mate
2019-01-19T17:54:44 < PeterM> cunt
2019-01-19T17:54:47 < rajkosto> oi
2019-01-19T17:54:55 < PeterM> thats not how inductors work
2019-01-19T17:55:19 < rajkosto> they work
2019-01-19T17:55:29 < rajkosto> 10pcs for 1$ all good
2019-01-19T17:56:23 < PeterM> ...
2019-01-19T17:57:43 < BrainDamage> currrent rating is wire thickness only if the core is not lossy
2019-01-19T17:57:58 < BrainDamage> spoiler: at high freq cores are pretty lossy
2019-01-19T17:59:01 < PeterM> inductors usually have 2 current ratings, one is the "rated current", which is temperature rise current (usually current for 25 or 40c rise), and a "saturation current", (usually the point that inductance drops by 30%), often the saturation current will be lower than the rated current 
2019-01-19T17:59:17 < PeterM> and that is also usually at a specific test frequency
2019-01-19T18:00:22  * karlp laughs out loud and edits zysnips
2019-01-19T18:00:29 < PeterM> so as frequency increases current handling decreases, and if you start to saturate your inductor, current rises very rapidly (because inductance drops) and you get into a bit of a vicious cycle
2019-01-19T18:01:50 < aandrew> PeterM: yep, sizing inductors is a bit tricky
2019-01-19T18:02:07 < aandrew> it's the same with digikey and "switch rating: 4A (3A)"
2019-01-19T18:03:34 < PeterM> a good way to estimate your absolute minimum saturation current is 1.15x your output current, because a reasonable delta I L is around 0.3x output current, and oyu want that swing to be +/- 0.15x so peak will be 1.15x, and thats your absolute minimum, because saturation current is when the inductance has already dropped by 30%
2019-01-19T18:04:37 < aandrew> PeterM: nice rule of thumb
2019-01-19T18:05:23 < aandrew> I need to build up a little tester that sweeps frequency and measures inductance
2019-01-19T18:05:46 < aandrew> tells me the current @ frequency
2019-01-19T18:06:10 < Steffanx> but you skipped all the interesting stuff now karlp.
2019-01-19T18:06:14 < PeterM> aandrew yeah, that is a bit annoying, though often not as bad because you should over-spec it a bit for efficiency
2019-01-19T18:07:48 < PeterM> usually it won't be too much difference in inductance with freq, but you will get heating much sooner

2019-01-20T00:46:04 < rajkosto> when something has no 3d model theres a clearance constraint in violation when they are too close
2019-01-20T00:46:05 < rajkosto> why this
2019-01-20T00:51:38 < Thorn> because without a 3d model altium uses maximal dimensions of the footprint to calculate clearance
2019-01-20T00:51:50 < rajkosto> how do i draw a fake 3d model it can use for clearance
2019-01-20T00:52:04 < rajkosto> i dont want the model to be there on NO-STUFF version of my components
2019-01-20T00:52:19 < Thorn> you can draw a box in the footprint editor itself
2019-01-20T00:52:34 < rajkosto> what layer
2019-01-20T00:52:36 < Thorn> place -> 3d body -> ...
2019-01-20T00:52:36 < rajkosto> it needs to be 2d only
2019-01-20T00:52:39 < rajkosto> no bodies
2019-01-20T00:52:56 < Thorn> 3d model == 3d body
2019-01-20T00:53:03 < rajkosto> yes i dont want 3d models
2019-01-20T00:53:18 < rajkosto> its "DNP" version of footprint, no model should show up
2019-01-20T00:53:50 < Thorn> you do want a 3d model. but it can be a simple box
2019-01-20T00:54:01 < rajkosto> i dont. want. 3d models.
2019-01-20T00:54:14 < rajkosto> it needs to just be the pads for the "DNP" footprint
2019-01-20T00:54:39 < Thorn> that's not how altium disaster works
2019-01-20T00:55:00 < rajkosto> can i have a model but not show it
2019-01-20T00:55:22 < Thorn> maybe, not sure

2019-01-20T01:53:19 < englishman> a thruhole smt electrolytic
2019-01-20T01:54:17 < rajkosto> you may be asking why would you mirror a 3d body when you cant do that irl
2019-01-20T01:54:22 < rajkosto> but you can, if you bend the legs of a capacitor the other way
2019-01-20T02:08:06 < karlp> well, this has been fun.
2019-01-20T02:24:41 < bitmask> I dont have the best crimper and I messed up a lot of my connections (jst-xh, jst-ph, and some others) so I just re-crimped everything for this project and I'm a lot happier with it.  I want to solidify the connection though so I'm thinking of putting some epoxy on the connectors to help with strain relief, any thoughts?
2019-01-20T02:33:57 < karlp> make "no" changes, poke it in the dbeugger, get CS pin working.
2019-01-20T02:34:06 < karlp> unplug debugger, unplug hardware, replug, doesn't work anymore.

2019-01-20T06:02:48 < PeterM> ahh that feel when you're going through your BOM tying to find that one combination of resistors that isnt crazy huge for a voltage divider to save adding the 9.487k resistor to your bom...
2019-01-20T06:04:19 < englishman> cant afford the extra $0.0002 eh :( oz economy is really killing you isnt it
2019-01-20T06:05:20 < PeterM> nah, just dont want another reel of a random value part thats only going to be used once per board
2019-01-20T06:07:58 < englishman> i hear you i have a couple shelves full of $3 reels of e24 resistors
2019-01-20T06:08:24 < PeterM> dont we all?
2019-01-20T06:09:30 < englishman> i'd mail you the whole set but we already discussed the futility of recycling. to a chinese landfill they will go.
2019-01-20T06:11:16 < PeterM> tbh if i could stick em on a pallet and send em to china for free so they could re-reel them for use on farting novelty toys i probably would
2019-01-20T06:11:57 < englishman> too bad they aren't full of harmful petrochemicals. i could burn them too heat my home. fuckin rohs
2019-01-20T06:13:15 < PeterM> hahaha, do an oil change on all of your farm equiptment at the start of winter and stick the old oil into the oil burner heater
2019-01-20T06:14:22 < PeterM> but seriously, it is pretty annoying to have to add some random value resistor that you'll only use once to your bom

2019-01-20T07:07:52 < englishman> yeah they have too much shit
2019-01-20T07:07:53 < dongs> they got them from someone else
2019-01-20T07:08:08 < englishman> they bought aptina

2019-01-20T07:08:39 < englishman> they had dual conversion gain 12 years ago

2019-01-20T07:09:05 < dongs> cool
2019-01-20T07:09:31 < englishman> hynix sold their cmos division to megachips, which literally ran it into the ground and was left with nothing
2019-01-20T07:10:27 < englishman> in like 2001

2019-01-20T14:51:03 < Thorn> fun fact(?): electron apps seem to be more responsive than qt apps, e.g. vs code vs. qt creator
2019-01-20T14:51:17 < dongs> Lol.
2019-01-20T14:51:19 < Thorn> electron is html+javascript
2019-01-20T14:51:27 < dongs> thats because niggerscript apps dont do fucking anything of value
2019-01-20T14:51:46 < Thorn> vs code does much more than qt creator
2019-01-20T14:52:07 < dongs> it doesnt because its written in javashit
2019-01-20T14:53:13 < rajkosto> ground planes below power inductors is bad no no, right
2019-01-20T14:53:43 < karlp> qt creator can at least do "find all usages" right?
2019-01-20T14:53:46 < rajkosto> Thorn, old Skype was Qt
2019-01-20T14:53:48 < karlp> vs code couldn't
2019-01-20T14:53:50 < rajkosto> new Skype is webshit
2019-01-20T14:53:55 < rajkosto> guess which one was better
2019-01-20T14:53:57 < karlp> haven't tried qtcreator for a while
2019-01-20T14:54:20 < Thorn> karlp: intellisense setup is very tricky but once it is set up it can do cross reference stuff
2019-01-20T14:54:39 < rajkosto> new Skype doesnt even try to be usable on desktop, it just labels itself "Skype" in the taskbar instead of who you are talking to
2019-01-20T14:55:00 < karlp> Thorn: if it's possible at all, it was farrrrrr to hard to make work out of the box => bin
2019-01-20T14:56:30 < PeterM> rajkosto if the inductor is a shielded inductor, put the ground plane, if its an unshielded inductor, dont put it
2019-01-20T14:56:50 < PeterM> if you are referring to your chink inductors from yesterday, they're shielded

2019-01-20T18:51:14 < specing> He is the inventor of wirthian syntax... what Pascal, Ada, VHDL, ...

2019-01-20T18:54:54 < fenugrec> has anyone seen a handy visual chart with SOT+TO package size and outlines ? the ones I find aren't super comprehensive
2019-01-20T18:58:45 < Cracki> "comprehensive" might be tricky. there are lots of pcb rulers that have some common footprints on them.
2019-01-20T19:01:56 < PeterM> fenugrec i dont think it exists. most of the charts i see are just comparing similar packages or replacement packages, rather than highlighting all of the packages
2019-01-20T19:03:34 < fenugrec> right, but there's a finite, reasonable number of <= 6-pin packages, it's at most a few PDF pages
2019-01-20T19:04:49 < fenugrec> I can't be bothered to remember whether st-323 is smaller or equivalent to sc70 or TO-236
2019-01-20T19:05:35 < fenugrec> this one comes close, but doesn't have the SC and TO nomenclatures http://www.mccsemi.com/ProductSelectionGuides/SMDDimensionSelectionGuide.pdf

2019-01-20T23:22:13 < specing> one*
2019-01-20T23:22:20 < rajkosto> has it been used ?
2019-01-20T23:22:28 < jadew> if they're from alyexpress, they're just a shell around a smaller electrolytic cap, that's already degraded and which was recovered from the sewer
2019-01-20T23:22:38 < rajkosto> they degrade @ their rated temperature
2019-01-20T23:22:45 < rajkosto> at no use they usually dont degrade
2019-01-20T23:24:08 < jadew> I know they can dry out - is this what you mean by degradin?

2019-01-20T23:30:55 < antto> iskra sounds slavic
2019-01-20T23:31:19 < rajkosto> probably pretty bad quality then lol
2019-01-20T23:31:28 < rajkosto> ive encountered them a few times but only ages ago

2019-01-20T23:37:00 < bitmask> I see that in multiple places
2019-01-20T23:37:26 < karlp> probably no particular rule honestly.
2019-01-20T23:37:37 < karlp> I know you can get tantalum manganese and tantalum p oly in yellow,
2019-01-20T23:37:38 < bitmask> yea but its still probably tantalum, just doesnt mean anything
2019-01-20T23:37:55 < karlp> you can probal get alu poly and tant poly in  black or yellow too.
2019-01-20T23:41:45 < jadew> bitmask, not sure what you're trying to find or why, but the kind of cap is also important
2019-01-20T23:42:02 < karlp> fwiw, digi's alu poly search for smd will be 99% black.
2019-01-20T23:42:18 < karlp> and digikeys' tant and tant poly are mayb 85-90% yellow, with the rest black
2019-01-20T23:42:30 < jadew> unless you replace it with an alu poly, in which case you don't have to worry about derrating and shit like that
2019-01-20T23:42:56 < bitmask> its just whats on this nano clone, black and says C106, everywhere I look, that combo returns tantalum
2019-01-20T23:43:13 < karlp> hrmn, tant poly is actually more black than 10%
2019-01-20T23:43:23 < karlp> might be tant :)
2019-01-20T23:43:29 < jadew> yeah, but you can't replace a 16V alu polymer with a 16V tantalum mg polymer

2019-01-21T00:15:16 < aandrew> karlp: how long is your ground lead
2019-01-21T00:16:05 < karlp> it's slow as shihtt anyway.
2019-01-21T00:16:21 < karlp> what's worse is that the LA is now seeing it all perfectly again, now that there's a scope lead on it.
2019-01-21T00:16:25 < karlp> it's all fucking shit
2019-01-21T00:16:49 < karlp> it's been seeing mosi/sck flawlessly every time, but cs is either _never_ there, or _perfectly_ there,
2019-01-21T00:17:13 < karlp> which, despite that horrific ringing, would imply other problems than the ringing.

2019-01-21T00:21:29 < rajkosto> karlp needs more ground vias
2019-01-21T00:22:06 < karlp> it's much mor elikely to be the forks in probed traces IMO, those are almost definitly reflection central.
2019-01-21T00:22:23 < englishman> how fast is your spi
2019-01-21T00:22:36 < englishman> isnt it usually in "who cares" territory
2019-01-21T00:22:48 < karlp> yeah, thatt's what I was expecting.
2019-01-21T00:23:44 < karlp> it's like 1-4 Mhz or less, right now it's at 32MHZ/64, so really should be in the slow as shit, no problems case.

2019-01-21T01:21:10 < rajkosto> Viper-7 in ##electronics linked me to a couple of projects he made entirely in it
2019-01-21T01:21:29 < rajkosto> what would you tell a beginner to use for schematic/board design
2019-01-21T01:21:57 < R2COM> kicad
2019-01-21T01:22:03 < rajkosto> but that's.... weird
2019-01-21T01:22:20 < rajkosto> easyeda already has a fuckton of simple footprints included
2019-01-21T01:22:33 < R2COM> then pay proper $$ and get pro soft and stop complaining
2019-01-21T01:23:30 < R2COM> did o6  clone himself
2019-01-21T01:23:31 < rajkosto> altium is weird to get used to and you pretty much gotta build up your own schematic/footprint database too
2019-01-21T01:24:02 < R2COM> then go get your soft and stop complaining i guess?
2019-01-21T01:24:18 < rajkosto> i use altium, asking for someone who's totally a beginner
2019-01-21T01:24:28 < R2COM> i answered you
2019-01-21T01:25:09 < R2COM> there is no soft with all proper footprints
2019-01-21T01:25:18 < R2COM> one needs to make them all the time, and build up
2019-01-21T01:25:19 < specing> Kicad should be fine
2019-01-21T01:25:34 < R2COM> if someone is judging PCB soft by amount of included footprints then he is a dumbfuck
2019-01-21T01:25:53 < rajkosto> a beginner wanting to whip up a shitty arduino shield would only care about that pretty much
2019-01-21T01:26:06 < paul_99> rajkosto, I found a ton of decent tempalte foorprints for altium on github
2019-01-21T01:26:11 < rajkosto> yes
2019-01-21T01:26:13 < rajkosto> i use rutledge as base
2019-01-21T01:26:31 < rajkosto> but you HAVE to judiciously copy paste/modify to suit your needs, build up your library
2019-01-21T01:26:32 < paul_99> most standard part sizes, you do still have to do the schematic bit tho
2019-01-21T01:27:05 < rajkosto> everyone has their own naming/parameter/separation system so you cant just use someone elses
2019-01-21T01:27:32 < paul_99> its unnamed, just the footprint
2019-01-21T01:29:58 < paul_99> I ended up using this library for the footprint, then a script from csv for the schematic pin entry/names
2019-01-21T01:30:00 < paul_99> its pretty quick
2019-01-21T01:30:45 < rajkosto> most people use the altium footprint wizard for the footprint
2019-01-21T01:30:48 < rajkosto> which makes decent but generic ones
2019-01-21T01:32:05 < paul_99> takes longer then copy paste from an existing set
2019-01-21T01:33:07 < rajkosto> well over time i ended up with each project having a buncvh of its own schlib/pcblib with footprints and symbols all from different sources and named/parametrized differently cuz i just copy pasted from the internet
2019-01-21T01:33:08 < paul_99> each to their own, but naming in schematic entry was the bit that took time
2019-01-21T01:33:14 < paul_99> especialyl for BGA parts
2019-01-21T01:33:32 < rajkosto> for BGA it might be best to try and rip from the vault
2019-01-21T01:33:34 < rajkosto> just for the symbol
2019-01-21T01:33:53 < paul_99> again, the pcb bit is easy to find a template.. or use the wizard
2019-01-21T01:33:59 < rajkosto> if you can figure out how to separate it from cmplib
2019-01-21T01:33:59 < paul_99> its naming 100's of pins is a nightmare
2019-01-21T01:34:49 < rajkosto> so now im trying to name/parametrize/comment everything consistently and build up a global library
2019-01-21T01:34:55 < paul_99> you can just select and copy paste out of any existing library into your own footprint file
2019-01-21T01:35:04 < rajkosto> you can
2019-01-21T01:35:08 < rajkosto> not from cmplib tho from the vault
2019-01-21T01:35:19 < rajkosto> so what i do is make a schematic with it then use the "Build library from scematic" and then copy from there
2019-01-21T01:35:22 < rajkosto> and close it without saving

2019-01-21T05:32:22 < PeterM> what the fuck am i looking at
2019-01-21T05:32:24 < dongs> are you trying to make a... 160k trimpot?

2019-01-21T05:36:22 < dongs> rajkosto: i dont think you understand how this works
2019-01-21T05:36:39 < rajkosto> why not
2019-01-21T05:37:44 < dongs> youre tryting to make a ghetto decade box or something out of trimpots
2019-01-21T05:38:29 < rajkosto> why is that wrong
2019-01-21T05:46:48 < englishman> how about ADT5259

2019-01-21T05:47:26 < tpw_rules> fiber to the home?
2019-01-21T05:47:28 < tpw_rules> lol
2019-01-21T05:57:44 < PeterM> pots have contact bounce and also wear out, this is exaggerated on higher resistance pots, from the look of the net names, this appears to be a voltage divider for a feedback node, this can lead to unpredictable output whilst adjusting hte pot, or the output having no negative feedback if the pot goes open circuit. one way to help alleviate this is to tie the wiper to one end of the potentiometer 
2019-01-21T05:57:47 < PeterM> and use the resistance accross the pot, not the wiper. that way, if the wiper fails, the resistance is no more than the resistance of the pot
2019-01-21T05:59:22 < rajkosto> so just tie the wiper with the pin thats currently unused
2019-01-21T05:59:22 < rajkosto> got it
2019-01-21T06:00:31 < PeterM> also, if the supply requires precision control only at one extreme of the range, it may be worth while jsut using a logarithmic taper pot instead of a linear pot
2019-01-21T06:00:54 < rajkosto> its something completely inconsequential
2019-01-21T06:01:15 < PeterM> then why does it need 3 fucking pots?
2019-01-21T06:01:26 < rajkosto> to get to 155k
2019-01-21T06:02:37 < PeterM> get a 150k pot and stick 5k in series with it then
2019-01-21T06:06:30 < rajkosto> much more expensive than getting 3 and doesnt get me the finest control on the edge
2019-01-21T06:07:10 < dongs> 150k pot is more expensive than 3 random-valued pots + fixed R?
2019-01-21T06:07:11 < dongs> ok

2019-01-21T17:35:58 < specing> Thorn: do you like languages that were actually designed and not just built from what was handy at the time?
2019-01-21T17:36:23 < Thorn> exactly 
2019-01-21T17:36:24 < bitmask> with a heating application, the voltage only affects how fast it will heat up right? If you have 6 batteries either as 2s3p or 3s2p the higher voltage will heat up quicker but require less power to maintain temp and battery should be about the same?
2019-01-21T17:37:08 < bitmask> be the same = battery life
2019-01-21T17:37:34 < BrainDamage> battery life is better with higher voltage
2019-01-21T17:37:44 < BrainDamage> because less current = less internal heating in the battery
2019-01-21T17:38:01 < BrainDamage> and heating up the battery degrades both current charge and capacity
2019-01-21T17:38:21 < bitmask> well it will be way under the max current of the battery
2019-01-21T17:38:24 < bitmask> either way
2019-01-21T17:38:32 < BrainDamage> also heating in the battery might not be heating delivered to your thermal load
2019-01-21T17:38:34 < qyx> I think he asked how fast will the heating element heat
2019-01-21T17:38:36 < qyx> not the battery
2019-01-21T17:38:45 < bitmask> no, I want to know battery life
2019-01-21T17:39:27 < bitmask> and with a heating application wouldnt higher voltage always equal higher current?
2019-01-21T17:39:36 < bitmask> with a pure resistive load
2019-01-21T17:41:02 < BrainDamage> higher voltage means higher current, but remember you care about ratio of power in load vs power in battery
2019-01-21T17:41:24 < BrainDamage> so higher power overall, but better power ratio
2019-01-21T17:41:38 < BrainDamage> and higher power gets compensated by the controller
2019-01-21T17:41:49 < bitmask> right
2019-01-21T17:41:50 < bitmask> ok
2019-01-21T17:41:56 < bitmask> I'll stick with 12v then

2019-01-21T21:59:52 < superbia> Steffanx: i can't test , because i need to order new arduinos
2019-01-21T22:00:25 < nn7> I'm trying to flash an STM32F405 in DFU mode. I'm using TrueStudio and have compiled a binary. I'm using dfu-util to flash address 0x08000000. So far my test code isn't working. My suspicion is that whatever TrueStudio is generating is not what dfu-util wants.
2019-01-21T22:00:43 < superbia> for some reason, the 32u4 breadboarduinos i have use a mini usb plug, and since like 2018 they ship them with micro usb plugs which are 5mm less in width; so i can't fit them on these pcb's

2019-01-21T22:05:00 < nn7> I've tried an Intel Hex format, a Motorola S format, and a Binary format.

2019-01-21T22:06:58 < PaulFertser> nn7: it's probably not plain DFU but DfUsE

2019-01-21T22:12:37 < PaulFertser> nn7: doesn't look like you get any errors
2019-01-21T22:13:03 < nn7> which is why I suspect I'm not telling TrueStudio the right output format.
2019-01-21T22:13:46 < PaulFertser> nn7: why do not you just use objdump to convert from ihex to binary?
2019-01-21T22:14:08 < nn7> because I don't know what I'm doing and wouldn't know how to do that.
2019-01-21T22:14:30 < nn7> I'm lacking any sort of instructions, so your feedback is very helpful.
2019-01-21T22:14:34 < PaulFertser> nn7: arm-none-eabi-objdump -O binary /path/to/your.hex /path/to/your.bin
2019-01-21T22:15:20 < PaulFertser> nn7: in fact, you do not need ihex at all, objdump can convert to binary directly from elf.
2019-01-21T22:15:44 < nn7> ok, thanks! I'll give this a try
2019-01-21T22:16:41 < PaulFertser> dfu-util man page doesn't tell anything about ihex, only raw binaries and binaries with special dfuse suffix are supported.
2019-01-21T22:17:13  * PaulFertser sighs seeing OpenMoko mentioned

2019-01-21T22:20:05 < PaulFertser> Back then it felt like openmoko had a chance to establish a niche of user-friendly smartphones. Lots of support from enthusiasts, cool projects based on it etc etc. And from all that great story only dfu-util survived, heh.
2019-01-21T22:21:58 < PaulFertser> nn7: btw, developing for stm32 and not having an SWD (or JTAG) adapter is kinda suboptimal.
2019-01-21T22:26:33 < specing> openmoko was damn too expensive imo
2019-01-21T22:26:58 < specing> also it was doomed from the start due to closed modems
2019-01-21T22:27:31 < Steffanx> Reminds me of this new "open phone" that doesnt even have a modem.
2019-01-21T22:27:32 < Steffanx> LOL
2019-01-21T22:28:42 < emeb> voip/wifi only?
2019-01-21T22:29:36 < PaulFertser> specing: no, not really. The device was relatively cheap, you can look it up, it was much cheaper than e.g. iphone1. And the closed firmware for GSM module was partially available for modification for the openmoko engineers, so it was reasonable. 
2019-01-21T22:30:22 < Steffanx> yeah emeb
2019-01-21T22:31:42 < PaulFertser> Steffanx: all current mass-produced smartphones have shared memory with the modem, so that's unacceptable for a proper device. And USB modules are expensive, power-hungry and big.
2019-01-21T22:32:42 < Steffanx> Yeah, but meh.
2019-01-21T22:32:57 < PaulFertser> nn7: so, got it working? From your log it looks like all you need is just convert it to binary with objcopy, and that should be it.
2019-01-21T22:33:31 < PaulFertser> Steffanx: isn't AMT/ME meh? Isn't most of the modern IT?..
2019-01-21T22:35:38 < Steffanx> was more referring to an open sores "phone" without a sim slot without a modem that costs 1200 euro (atm) is a joke.
2019-01-21T22:38:48 < specing> PaulFertser: how much did it cost?
2019-01-21T22:38:56 < specing> I remember something insane like 800 eur 
2019-01-21T22:41:48 < PaulFertser> specing: that's neo900 preorders, not openmoko
2019-01-21T22:42:52 < PaulFertser> specing: $400 or so
2019-01-21T22:44:03 < PaulFertser> Compare to this: "The iPhone was released in the United States on June 29, 2007 at the price of $499 for the 4 GB model and $599 for the 8 GB model, both requiring a 2-year contract."

2019-01-21T22:51:27 < invzim> any led experts about?  
2019-01-21T22:51:50 < invzim> I usually go with 1k resistor and it works ok and don't think anything more about it
2019-01-21T22:52:01 < rajkosto> invzim, what led
2019-01-21T22:52:21 < invzim> pretty much whatever, for power indication and stuff
2019-01-21T22:52:23 < rajkosto> Vres = Supply_Voltage - Led_Forward_Voltage
2019-01-21T22:52:37 < rajkosto> LedCurrent = Vres / Rres
2019-01-21T22:52:40 < invzim> yeah, I never bothered being anal about that stuff as 1K has served me well :)
2019-01-21T22:52:48 < rajkosto> 1k is waaay too much for SMD leds for me
2019-01-21T22:52:51 < rajkosto> 10k more like
2019-01-21T22:52:54 < rajkosto> or you get blinded
2019-01-21T22:53:11 < invzim> anyhoo, assembly house suggests this
2019-01-21T22:53:13 < invzim> https://datasheet.lcsc.com/szlcsc/Lite-On-LTST-C191KRKT_C125099.pdf
2019-01-21T22:53:32 < invzim> on page 4 it lists the intensity as min 18, max 180, typ 54
2019-01-21T22:53:36 < invzim> which is a rather large span?!
2019-01-21T22:53:38 < rajkosto> standard 0805 ?
2019-01-21T22:53:47 < rajkosto> yes it depends on what current you push through it
2019-01-21T22:53:49 < invzim> 0603
2019-01-21T22:54:02 < invzim> proto uses something marked 100-120mcd, 20mA
2019-01-21T22:54:10 < invzim> which works fine (with 1k :))
2019-01-21T22:54:25 < rajkosto> forward voltage is 2.0
2019-01-21T22:54:32 < rajkosto> if supply is 3.3v then resistor voltage is 1.3
2019-01-21T22:55:30 < rajkosto> http://ledcalc.com/
2019-01-21T22:58:24 < Thorn> I use 270...360Ω for smd leds, what do you mean 10K
2019-01-21T22:58:44 < rajkosto> 10k works just fine, doesnt blind me, with 0805s, looking at them straight on
2019-01-21T22:59:06 < Thorn> are you a cat
2019-01-21T22:59:10 < rajkosto> nop
2019-01-21T22:59:31 < rajkosto> keep in mind blue has a higher voltage than red/green
2019-01-21T22:59:49 < rajkosto> anyway use calculator for desired milliamps through led, done
2019-01-21T23:00:13 < rajkosto> if its connected straight through leg of STM32, keep in mind the maximuim per-pin drive currents, and maximum per-chip IO current
2019-01-21T23:00:26 < invzim> nah, for this it's straight after the LDO
2019-01-21T23:02:16 < rajkosto> if you have proto, and you did 1k and the brightness is good, use 1k
2019-01-21T23:02:29 < invzim> yes, but this is a different led
2019-01-21T23:03:39 < invzim> ah, it will emit SOMETHING for sure
2019-01-21T23:03:46 < invzim> it's just to confirm power
2019-01-21T23:03:55 < rajkosto> is it the same COLOR of led ?
2019-01-21T23:03:57 < invzim> i'll approve and redo next batch if terible
2019-01-21T23:04:00 < rajkosto> is it also SMD ?
2019-01-21T23:04:02 < invzim> yup, RED
2019-01-21T23:04:03 < invzim> smd
2019-01-21T23:04:04 < invzim> :)
2019-01-21T23:04:09 < rajkosto> then it will be approx the same
2019-01-21T23:04:33 < rajkosto> just depends on led efficiency
2019-01-21T23:04:38 < invzim> allright, had some leds previously I think that was noticably dimmer
2019-01-21T23:05:09 < nn7> PaulFertser, I understand it's suboptimal. This is kind of a specialized case that I'm dealing with.
2019-01-21T23:06:05 < nn7> PaulFertser, one place you say objcopy another you say objdump
2019-01-21T23:06:39 < nn7> although TrueStudio will create a binary version, so maybe my problem is elsewhere.
2019-01-21T23:13:21 < mawk> with extension .bin ?
2019-01-21T23:13:25 < mawk> you checked right ?
2019-01-21T23:13:34 < mawk> also DFU is a special format, you can't flash the raw thing
2019-01-21T23:13:37 < mawk> you need nice headers and stuff
2019-01-21T23:14:24 < mawk> read the specs and put the headers yourself, or if you're on windows use the program made by ST
2019-01-21T23:15:24 < invzim> I use the dfu filemanager thingie, works great
2019-01-21T23:16:09 < invzim> push the bootloader via USB in same step as verifying power entry
2019-01-21T23:19:35 < nn7> Well, I had made the code incredibly simple, "turn on LED". Couldn't get it working. Tried adding "delay, turn off LED, delay" to make sure I had the polarity right, didn't work.
2019-01-21T23:19:53 < nn7> Added sending text through the UART, both UART and LED are working.
2019-01-21T23:19:54 < nn7> <shrug>
2019-01-21T23:20:12 < rajkosto> whats the point of a 10m resistor
2019-01-21T23:20:16 < rajkosto> mega*
2019-01-21T23:20:33 < nn7> resisting a lot?
2019-01-21T23:20:38 < rajkosto> to ground
2019-01-21T23:21:30 < nn7> we used them to simulate the shunt resistance of a photodiode when testing ADC's
2019-01-21T23:21:43 < mawk> yeah nn7 but you need a proper dfu file format
2019-01-21T23:21:45 < mawk> not just binary
2019-01-21T23:21:49 < mawk> else, don't use DFU
2019-01-21T23:21:51 < mawk> flash the binary directly
2019-01-21T23:21:59 < nn7> mawk, dfu-util flashes the binary 
2019-01-21T23:29:01 < rajkosto> 2.54mm headers are huge, what smaller connector do i use
2019-01-21T23:29:57 < catphish> for what?
2019-01-21T23:30:10 < rajkosto> was thinking some sort of flat flex
2019-01-21T23:30:31 < rajkosto> just board to board
2019-01-21T23:38:54 < Cracki> 1.27mm ribbon?
2019-01-21T23:38:58 < Cracki> .63mm ribbon?
2019-01-21T23:39:26 < Cracki> ribbon soldered or ribbon with Insulation Displacement Connectors
2019-01-21T23:39:44 < Cracki> ribbon steamed, ribbon sauteed, ...
2019-01-21T23:40:04 < rajkosto> boil em mash em stick em in a stew ?
2019-01-21T23:40:28 < Cracki> tasty chemicals
2019-01-21T23:41:22 < Cracki> there are 1.27mm pitch pin headers too. IIRC cortex m debug header is 2x5 pin with that pitch

2019-01-21T23:42:30 < Cracki> 0.5mm flatflex is a commodity so if it makes sense, why not
2019-01-21T23:42:39 < rajkosto> why not 1.0mm
2019-01-21T23:42:43 < rajkosto> easier to solder if i need to bodge
2019-01-21T23:42:45 < Cracki> sure, that too
2019-01-21T23:43:36 < rajkosto> now i remember flat flexd has weird "forward" and "reverse" types

2019-01-21T23:45:00 < qyx> opossite wat
2019-01-21T23:45:18 < qyx> the first was right
2019-01-21T23:53:40 < Cracki> most common is one plane of contacts, that are exposed up/down/both on each side
2019-01-21T23:54:01 < aandrew> karlp: that USB3340 --> FT2232 works. microchip documentation team has their heads up their asses
2019-01-21T23:54:03 < Cracki> double-layer copper is also possible but I guess nobody uses that
2019-01-21T23:54:51 < Cracki> just recently someone here had a flatflex connector that touched the end from top and bottom, so you could feed it any type of ribbon. just make sure pin 1 is on the right end
2019-01-21T23:56:48 < rajkosto> those would be the best
2019-01-21T23:56:51 < rajkosto> but most are one side only
2019-01-21T23:57:01 < rajkosto> so you have to match it with the cable, which is either top-top or bottom-bottom or top-bottom

2019-01-22T00:05:15 < Cracki> unless you have some keying which is... nonstandard
2019-01-22T00:05:53 < Cracki> I would always use same-side by default, unless opposite-side makes construction easier
2019-01-22T00:07:11 < Cracki> figuring from mechanical construction, I'd say bottom-contact connectors are easier. fixed contacts, and the top is just for fastening

2019-01-22T03:15:28 < Cracki> no clue how they made multitouch work for that
2019-01-22T03:17:11 < Cracki> one secret they did admit to was "touching a few pixels as possible" to keep latency down... but as soon as you echo that back, they act like they should have switched off all the measurement markings in their pictures that give the idea away

2019-01-22T03:22:50 < Cracki> you have no clue
2019-01-22T03:23:09 < specing> cs people sure love python these days 
2019-01-22T03:23:21 < tpw_rules> faster than matlab
2019-01-22T03:23:35 < specing> try Octave ;)
2019-01-22T03:23:47 < tpw_rules> if i didn't want good toolboxes, i would just use python
2019-01-22T03:29:17 < tpw_rules> the big problem with matlab is that the language is absolutely bonkers garbage, and octave embraces that with open arms
2019-01-22T03:32:07 < specing> there is sci-lab, too
2019-01-22T03:32:16 < specing> Though I'm not sure what they are thinking
2019-01-22T03:32:21 < Cracki> mathworks would get so many fanboys if they'd support python to glue all their toolboxes together

2019-01-22T03:33:08 < tpw_rules> but like i have literally every toolbox available for free, legitimately. still not worth to use them
2019-01-22T03:33:15 < specing> uh oh, webapp
2019-01-22T03:33:18 < Cracki> that's not quite matlab tho, because matlab is its toolboxes and you only get them with matlab
2019-01-22T03:33:38 < Cracki> the most bitching about matlab I hear is from people who have no clue what all these toolboxes can do... they don't even know simulink
2019-01-22T03:34:08 < tpw_rules> jupyter is okay
2019-01-22T03:34:20 < tpw_rules> it's not quite the same as matlab's ide and that's kind of annoying. like there's no variable explorer
2019-01-22T03:34:38 < Cracki> "notebooks" is what matlab, mathematica, ... emacs, ... did for decades
2019-01-22T03:34:49 < tpw_rules> matlab notebooks are crap
2019-01-22T03:35:05 < Cracki> something like matlab, but for python, that'd be nice. variables lying around in a workspace, explorable, ...
2019-01-22T03:35:13 < tpw_rules> but if i could use matlab and keep everything except the matlab language, i might actually pay them the $99 for my own copy
2019-01-22T03:35:39 < specing> wht I really like about matlab's language is that by omitting ; you get the result printed
2019-01-22T03:35:46 < Cracki> people recommended me "spyder". not sure what to make of it.
2019-01-22T03:35:47 < tpw_rules> same in python, actually :P
2019-01-22T03:36:07 < tpw_rules> ooh that looks neat
2019-01-22T03:36:44 < tpw_rules> also to be honest omitting the ; and accidentally printing a 1000x1000 matrix annoys me more than it's useful
2019-01-22T03:37:01 < Cracki> matlab and numpy abbreviate those
2019-01-22T03:37:05 < tpw_rules> eew it's conda
2019-01-22T03:37:24 < Cracki> python doesn't abbreviate its own data structures, but numpy knows it's a feature
2019-01-22T03:37:26 < tpw_rules> numpy does. maybe matlab will for 1000x1000 but i do it by accident often enough to get annoyed
2019-01-22T03:38:00 < Cracki> I don't like conda either. their package pile is shit
2019-01-22T03:38:14 < tpw_rules> yeah
2019-01-22T03:38:16 < Cracki> every dumb fucker can just publish their pozzed shit
2019-01-22T03:39:16 < Cracki> it's even starting in pypi... needed pycryptoplus recently, some dude grabbed the identifier and retargeted it to cryptodome instead of pycrypto... but cryptodome dropped some shit, and he missed that, so it wouldn't build just like that
2019-01-22T03:40:38 < Cracki> appalling, the hoops I have to jump through just to get a script using aes-xts working again
2019-01-22T03:40:49 < tpw_rules> is miniconda not a thing anymore
2019-01-22T03:41:01 < tpw_rules> >ppc64le
2019-01-22T03:41:02 < Cracki> "little shit" doesn't change the flavor
2019-01-22T03:41:12 < tpw_rules> yeah i know but i wanted to give scipy a try
2019-01-22T03:41:18 < tpw_rules> spyder*
2019-01-22T03:41:28 < Cracki> scipy is its own package, no need for any conda
2019-01-22T03:41:34 < Cracki> ah, does it require conda?
2019-01-22T03:41:52 < tpw_rules> yeah there's a big scary warning about trying to install it outside of conda
2019-01-22T03:41:57 < tpw_rules> it sure is encouraging™ that apparently i can't just install conda in a directory
2019-01-22T03:42:05 < Cracki> spyder is on pypi so it shouldn't need it
2019-01-22T03:42:07 < tpw_rules> anything that requires an installer scares me
2019-01-22T03:42:34 < Cracki> smells like Continuum is developing that... and they want to push their shit
2019-01-22T03:42:55 < Cracki> just like intel is in the process of fucking up opencv to suit their needs and theirs alone
2019-01-22T03:43:18 < Cracki> they recently removed some quite (old but) fundamental algorithms because nobody at intel gives a shit
2019-01-22T03:44:00 < tpw_rules> excellent
2019-01-22T03:44:32 < Cracki> kek spyder has notebooks too
2019-01-22T03:44:50 < Cracki> nvm, they're not, they're just html output
2019-01-22T03:45:29 < Cracki> ... and qwebengine hosting a jupyter
2019-01-22T03:45:58 < tpw_rules> welp it installed just fine with pip
2019-01-22T03:46:58 < tpw_rules> there's a static code analysis button and it gave my code a score of -10/10

2019-01-22T05:05:49 < Cracki> wow
2019-01-22T05:16:38 < aandrew> Cracki: sounds plausible
2019-01-22T05:16:42 < aandrew> it's 8 minutes to the sun
2019-01-22T05:17:10 < Cracki> earth-sun is pretty stable, but earth-mars is wild because we're both on orbits around the sun
2019-01-22T05:17:14 < aandrew> yep
2019-01-22T05:17:17 < rajkosto> actually, it woudl be better if i used something like a ad5259 but WITHOUT the eeprom
2019-01-22T05:17:21 < aandrew> which is why the estimate is so wide
2019-01-22T05:17:34 < rajkosto> as i will be setting the value via stm32 with its own eeprom/battery backup anyway
2019-01-22T05:17:44 < Cracki> this always trips me up... sometimes a roundtrip being 40+ minutes, sometimes way less
2019-01-22T05:17:51 < aandrew> hm, I was hoping I could set the FTDI modes without their fucking library
2019-01-22T05:17:58 < rajkosto> nop
2019-01-22T05:18:00 < aandrew> they're just vendor requests, I shouldn't have to use that idiotic library
2019-01-22T05:18:01 < Cracki> decompile library
2019-01-22T05:18:08 < rajkosto> aandrew, you need the nda'd datasheet
2019-01-22T05:18:08 < Cracki> sniff usb?
2019-01-22T05:18:15 < aandrew> yeah I could just sniff it
2019-01-22T05:18:21 < aandrew> just surprisd it's not already online
2019-01-22T05:18:32 < rajkosto> i have the nda'd datasheet for 2232h and it let me just use WinUSB
2019-01-22T05:18:45 < aandrew> what's the filename?
2019-01-22T05:18:47 < rajkosto> there's some of it reverse engineered in libftdi or whatever, that goes over libusbk
2019-01-22T05:18:49 < aandrew> I'll see if I can find it online
2019-01-22T05:19:14 < rajkosto> i have no idea, ftdi sent it to me
2019-01-22T05:19:47 < aandrew> actually maybe I don't need to, I bet openocd already does it
2019-01-22T05:19:59 < rajkosto> if youre asking about mpsse
2019-01-22T05:20:00 < rajkosto> its already in that mode
2019-01-22T05:20:17 < rajkosto> you only need stuff to get it into the fast fifo and 8-bit modes
2019-01-22T05:20:24 < rajkosto> and UART is an eeprom setting
2019-01-22T05:20:28 < aandrew> well my board is just defaulted
2019-01-22T05:20:41 < aandrew> need JTAG on ADBUS and UART on BDBUS
2019-01-22T05:20:43 < rajkosto> so as long as its not in UART mode on that channel, you can use mpsse right away (just perform the reset and synchronisation)
2019-01-22T05:20:48 < rajkosto> then you need an eeprom
2019-01-22T05:20:53 < rajkosto> the 16 byte one will do
2019-01-22T05:21:05 < aandrew> I have one, but FTDI said I didn't need it, I could just issue the command to set teh mode 
2019-01-22T05:21:07 < rajkosto> use the ftdiprog thing to set B to uart
2019-01-22T05:21:15 < aandrew> yeah
2019-01-22T05:21:15 < rajkosto> nah, UART switches the driver used.
2019-01-22T05:21:22 < aandrew> oh right
2019-01-22T05:21:25 < aandrew> that was the trick
2019-01-22T05:21:43 < rajkosto> if youre got an eeprom attached just program it
2019-01-22T05:22:53 < aandrew> yeah
2019-01-22T05:23:03 < rajkosto> for openocd you have to manually install libusbk driver for channel A anyway
2019-01-22T05:23:09 < rajkosto> or libftdi cant find it
2019-01-22T05:23:19 < rajkosto> (on windows, on linux its automatic libusb anyway)
2019-01-22T05:25:38 < rajkosto> PeterM, ok for my ACTUAL feedback resistor, i need value from 19.624k to 245.308k and i want to control it via stm32 if possible, what use
2019-01-22T05:28:18 < tpw_rules> continuous servo and 10 turn pot
2019-01-22T05:28:53 < Cracki> so you need to emulate a resistor... how is the resistor electrically "used"?
2019-01-22T05:29:02 < Cracki> this either means creating voltage, or creating current
2019-01-22T05:30:07 < Cracki> first is a dac, that's simple. second... requires knowing some electrical engineering to pick a standard current source that's adjustable in a way you can adjust it
2019-01-22T05:30:25 < rajkosto> https://images.sshnuke.net/2019-01-22_04-30-24_EEKUQ3HTX.png
2019-01-22T05:30:28 < rajkosto> used like this
2019-01-22T05:30:40 < Cracki> what does that do

2019-01-22T05:30:54 < rajkosto> controls current
2019-01-22T05:30:58 < rajkosto> in a linear fashion
2019-01-22T05:30:58 < Cracki> what does the thing with its corner visible do with it
2019-01-22T05:31:02 < Cracki> gief name, gief shiet
2019-01-22T05:31:08 < rajkosto> http://www.ti.com/lit/ds/symlink/tps61196.pdf
2019-01-22T05:32:01 < Cracki> I see V_ISET nominall 1.229 volts...
2019-01-22T05:32:08 < Cracki> is that doing a current mirror or what
2019-01-22T05:32:14 < rajkosto> no idea
2019-01-22T05:32:21 < Cracki> ah it does
2019-01-22T05:32:23 < rajkosto> 1.229v is always on that pin
2019-01-22T05:32:24 < Cracki> K_ISET
2019-01-22T05:32:28 < Cracki> I_IFB / I_ISET
2019-01-22T05:32:40 < Cracki> K_ISET is 3992
2019-01-22T05:33:12 < Cracki> so... you get to be a current sink
2019-01-22T05:33:29 < Cracki> yeah, servo and ten turn pot
2019-01-22T05:33:53 < Cracki> very simple :P maybe some electrical engineer knows how to make a programmable current sink
2019-01-22T05:34:06 < rajkosto> you never heard of a digital potentiometer ?
2019-01-22T05:34:07 < rajkosto> https://www.analog.com/media/en/technical-documentation/data-sheets/ad5259.pdf
2019-01-22T05:34:13 < rajkosto> wouldnt that work
2019-01-22T05:34:22 < Cracki> dunno, does it give the range you need
2019-01-22T05:35:33 < Cracki> now you need to calculate the current you need, and the current required at ISET, and see if your digital pot has the right resistance for that I and V
2019-01-22T05:36:23 < rajkosto> why would that matter
2019-01-22T05:36:44 < rajkosto> if i can find 200k digital potentiometer, i add 20k in series
2019-01-22T05:36:46 < rajkosto> god enough
2019-01-22T05:37:13 < Cracki> just saying, you can figure out the limits, and whether the limits are acceptable to you, before you buy a part
2019-01-22T05:37:47 < aandrew> rajkosto: do you put it in CPU FIFO or F232 FIFO mode for MPSSE/JTAG?
2019-01-22T05:37:59 < rajkosto> neither
2019-01-22T05:38:05 < aandrew> I have only four options
2019-01-22T05:38:13 < rajkosto> mpsse has its own initialization mode
2019-01-22T05:38:21 < rajkosto> use f232 fifo then
2019-01-22T05:38:37 < aandrew> I have "RS232 UART" "245 FIFO" "CPU FIFO" and "OPTO Isolate"
2019-01-22T05:38:44 < Cracki> as for the resistance at ISET... it fucks off to infinity if you want the current to go down... so you will have a minimum current before "off"
2019-01-22T05:40:30 < Cracki> (assuming that digital pot can be switched to high impedance/disconnect)

2019-01-22T05:41:55 < rajkosto> aandrew, i think the 2 fifo modes only have a different at what the pins initially are set up, pulldown/pullup wise
2019-01-22T05:42:03 < rajkosto> mpsse mode works in either
2019-01-22T05:42:19 < rajkosto> and you reconfigure the port pins as you wish then
2019-01-22T05:42:23 < aandrew> right
2019-01-22T05:42:34 < rajkosto> Cracki, cant find 200k digital pot
2019-01-22T05:42:51 < aandrew> if I understand, the biggest thing is to set it so it asks for the FTDI driver not VCP
2019-01-22T05:43:02 < rajkosto> thats just uart vs everything else
2019-01-22T05:43:05 < rajkosto> also "Load VCP driver" checkbox
2019-01-22T05:43:14 < Cracki> you said 19.624-245.308k... can you narrow that down
2019-01-22T05:43:18 < aandrew> yes but that's what prevents the VCP from grabbing it
2019-01-22T05:43:21 < rajkosto> Cracki, i can do 20k to 220k
2019-01-22T05:43:27 < rajkosto> so 20k static + 200k digital
2019-01-22T05:43:31 < Cracki> good
2019-01-22T05:43:34 < Cracki> otherwise two in series
2019-01-22T05:45:58 < Cracki> or... google "current sink circuit" and see what suits you
2019-01-22T05:46:18 < Cracki> can be had as an IC too
2019-01-22T05:46:44 < Cracki> then you have an actual proportional relationship, not inversely proportional

2019-01-22T05:49:04 < englishman> raj idk i'm not a datasheet
2019-01-22T05:49:27 < rajkosto> https://www.analog.com/media/en/technical-documentation/data-sheets/ad5243_5248.pdf the AD5248 here has ONLY wiper and B, no A terminal
2019-01-22T05:49:58 < rajkosto> so maybe better as i dont need voltage divider, instead just variable resistor
2019-01-22T05:50:07 < Cracki> they're the same
2019-01-22T05:50:12 < Cracki> for the first, you'd leave one pin disconnected
2019-01-22T05:50:17 < rajkosto> https://images.sshnuke.net/2019-01-22_04-50-15_oCtDoq2Gy.png
2019-01-22T05:50:26 < rajkosto> calls one "WIPER" vs "RDAC"
2019-01-22T05:50:33 < Cracki> you mustn't run it as a divider anyway because that first chip needs resistance, not voltage
2019-01-22T05:50:47 < rajkosto> i know but most of these are designed to be dividers
2019-01-22T05:50:53 < Cracki> because it's an RDAC
2019-01-22T05:51:08 < englishman> cool, 200kW charging stations going in
2019-01-22T05:52:02 < Cracki> read up on the construction of these things. they're probably a bunch of switches defining the current path through a bunch of resistors, such that it is equivalent to a wiper
2019-01-22T05:52:32 < rajkosto> Cracki, well i know that some other design using the same TI chip... has a bunch of transistors shorting resistors on the board, with GPIO bins going to their bases
2019-01-22T05:52:49 < Cracki> the single ended ones don't need to set up the "second leg" so that's simpler, or leaves more resolution I guess
2019-01-22T05:52:59 < Cracki> sounds plausible
2019-01-22T05:53:39 < Cracki> that's a simple structure then, combining one end _and_ the switching into gpio
2019-01-22T05:53:57 < rajkosto> yeah but i dont have that many gpio pins free
2019-01-22T05:54:07 < rajkosto> i2c digital potentiometer should work better and use less space
2019-01-22T05:54:10 < Cracki> your chip wants one end to ground anyway
2019-01-22T05:54:15 < Cracki> ya use it then
2019-01-22T05:54:30 < Cracki> or, if you want to play with opamps: https://www.analog.com/en/design-center/reference-designs/circuit-collections/lt1001-precision-current-sink.html#cc-overview
2019-01-22T05:54:36 < rajkosto> really dont
2019-01-22T05:54:52 < rajkosto> so just short B1 to W2 and the 2 channels will be in series ?
2019-01-22T05:55:27 < Cracki> uh sounds possible, but do check the sheet for any limitations
2019-01-22T05:56:43 < Cracki> heh, fig 38, equivalent circuit. very interesting.
2019-01-22T05:59:09 < rajkosto> lcsc ships free if you get pcbs at the same time right ?
2019-01-22T05:59:40 < Cracki> not quite sure if they mean to suggest eight stages, or 256... because if they have eight stages, and more than one switches the "resistor backbone" to the wiper, you get a shortcut between A and B

2019-01-22T06:00:12 < rajkosto> im going to turn the device off, set the resistance, then turn it on
2019-01-22T06:00:16 < rajkosto> any glitches dont matter
2019-01-22T06:00:41 < Cracki> no I mean if this were binary coded like a normal DAC, you'd have any of eight signals on or off at the same time
2019-01-22T06:01:56 < Cracki> looks like it won't produce (noticeable) glitches anyway because I think it uses 256 small resistors in series and that many switches/transistors/mosfets
2019-01-22T06:01:59 < rajkosto> A isnt even on the chip im getting
2019-01-22T06:02:05 < rajkosto> just B and wipe
2019-01-22T06:02:44 < Cracki> the single ended one could have a simpler, exponential, construction
2019-01-22T06:06:13 < rajkosto> Because there is
2019-01-22T06:06:13 < rajkosto> a 160 Ω wiper contact resistance

2019-01-22T06:10:01 < rajkosto> having A and not using B would be cool as then value of 0 in the digital pot means lowest current (highest resistance)
2019-01-22T06:10:09 < rajkosto> but in a stm32 i can just subtract values so its no big deal
2019-01-22T06:10:44 < Cracki> check the tolerances...
2019-01-22T06:10:57 < Cracki> a bit here and there won't matter. these things don't promise much.
2019-01-22T06:11:10 < rajkosto> lcsc doesnt have the one that has A though (AD5243) so gotta go with B
2019-01-22T06:11:20 < Cracki> I've also not found any description of what happens when you program a different value while it's getting voltage to its terminals
2019-01-22T06:11:32 < rajkosto> it updates, supposedly glitchless
2019-01-22T06:12:14 < Cracki> that would involve disconnecting the wiper, or moving by increments between old and new value
2019-01-22T06:12:27 < rajkosto> no wait this one has glitches https://images.sshnuke.net/2019-01-22_05-12-23_Eo3TbKWGA.png
2019-01-22T06:12:34 < rajkosto> the other one didnt
2019-01-22T06:12:38 < Cracki> jumping would otherwise short the distance
2019-01-22T06:12:51 < Cracki> the AB should glitch, the single-ended one should not
2019-01-22T06:13:02 < rajkosto> well they put the same datasheet for both
2019-01-22T06:13:11 < Cracki> the single ended one can be made with 1,2,4,8,...128xR array
2019-01-22T06:13:13 < rajkosto> they dont make a difference between them anywhere other than the pinouts
2019-01-22T06:13:15 < Cracki> they're asses
2019-01-22T06:13:37 < Cracki> that's a specialty part and nobody bitches at them to make the shiet better
2019-01-22T06:13:43 < rajkosto> if you measure these with a multimeter, it would measure exactly like a normal resistor would, no ?
2019-01-22T06:13:48 < rajkosto> its not that special
2019-01-22T06:13:49 < Cracki> yep
2019-01-22T06:14:01 < rajkosto> theres similar things made by microchip etc, used for digital volume control
2019-01-22T06:14:17 < Cracki> it's special. the thickness of the datasheet says so.
2019-01-22T06:14:59 < Cracki> nvm, they actually do use the word "glitch" once

2019-01-22T07:18:13 < rajkosto> that hair is growing a few cultures for sure
2019-01-22T07:18:16 < con3> she looks nice
2019-01-22T07:27:25 < Cracki> don't touch that without a good delousing
2019-01-22T07:30:19 < rajkosto> Cracki, that resistor doesnt say if AD0/1 pins have internal pullups or pulldowns or nada
2019-01-22T07:30:38 < Cracki> uh
2019-01-22T07:30:43 < Cracki> then maybe it has none of that
2019-01-22T07:30:58 < rajkosto> the AD5243 is fixed to to 1,1 
2019-01-22T07:30:59 < Cracki> I'd go with the equivalent circuit
2019-01-22T07:31:00 < rajkosto> so i assume it has pull ups
2019-01-22T07:34:08 < rajkosto> i wired it like this https://images.sshnuke.net/2019-01-22_06-34-06_kUYdXyOhe.png
2019-01-22T07:35:01 < rajkosto> its actually slightly larger than the smd potentiometers https://images.sshnuke.net/2019-01-22_06-34-51_kgc6dVkcd.png

2019-01-22T07:36:52 < rajkosto> just address selection bits
2019-01-22T07:36:53 < rajkosto> for i2c
2019-01-22T07:36:57 < Cracki> oh, fuck that then
2019-01-22T07:37:10 < Cracki> you can skip the Rs if you want
2019-01-22T07:37:18 < Cracki> but no backsies then
2019-01-22T07:37:18 < rajkosto> yeah but i like to wire them so that its the opposite of what they are without anything connected
2019-01-22T07:37:25 < rajkosto> then i can DNP the resistors if i want it the other way 
2019-01-22T07:37:33 < Cracki> makes sense
2019-01-22T07:38:33 < rajkosto> does it matter if it goes SIG->W1->B1->W2->B2->GND or GND->W1->B1->W2->B2->SIG

2019-01-22T07:59:58 < rajkosto> makes routing easier, doesnt break up the board as much
2019-01-22T08:08:56 < Cracki> solder bridge
2019-01-22T08:09:07 < rajkosto> nah, forced gnd
2019-01-22T08:09:12 < rajkosto> way nicer routing with no vias needed for i2c
2019-01-22T08:09:26 < Cracki> it's like a resistor but you don't feel it when you inhale it
2019-01-22T08:09:38 < rajkosto> ive never inhaled resistors, not even 0201
2019-01-22T08:09:42 < rajkosto> they are too heavy for that
2019-01-22T08:09:47 < Cracki> orly
2019-01-22T08:10:00 < Cracki> you can sniff them

2019-01-22T12:46:13 < zyp> charges while you drive, so you never have to plug it in, etc…
2019-01-22T12:46:15 < Haohmaru> haven't seen them.. they're not very popular here
2019-01-22T12:46:57 < Haohmaru> we still mostly drive EU's "thrown away" cars
2019-01-22T12:47:29 < zyp> I'm not sure those commercials are run elsewhere
2019-01-22T12:48:24 < zyp> in norway, EVs have a fairly large market share
2019-01-22T12:48:51 < Haohmaru> i know, my cousin lives there and he bought an electric car a few years ago coz it woz cheap0r
2019-01-22T12:49:05 < zyp> I guess counting both plain EVs and plug-in hybrids, they've had over half the market for a while

2019-01-22T12:49:26 < zyp> so toyota is marketing shit as «it's electric, but you don't have to plug it in!»
2019-01-22T12:49:56 < zyp> which is pretty dumb
2019-01-22T12:50:02 < karlp> toyota is in trouble here for their ads for their hybrids.
2019-01-22T12:50:09 < Haohmaru> i thought they all would have a generator thing.. or generative breaks or something
2019-01-22T12:50:12 < Haohmaru> dynamo shizzle
2019-01-22T12:50:21 < karlp> they cooked some figures to get 50% more range and 50% electric shit, 
2019-01-22T12:50:33 < karlp> and people were like, uh, no. stahp
2019-01-22T12:50:51 < zyp> they are essentially saying «you can't plug it in», which is a pretty dumb thing to market when electricity is like one fifth of the price of gasoline per km driven
2019-01-22T12:50:52 < karlp> and they've currently just kept the same campagain with a tiny star at the bottom saying, "according to our blah methods"

2019-01-22T12:51:59 < Haohmaru> "* according to our highly biased, hand-twisting, pseudo-accurate lab tests"
2019-01-22T12:55:13 < jpa-> i don't really understand why non-plugggable hybrids even exist
2019-01-22T12:55:45 < jpa-> even a crappy small battery with crappy slow charger could handle many people's daily work commute
2019-01-22T12:55:59 < Haohmaru> they only way to charge those is to pour fuel in them?
2019-01-22T12:56:26 < specing> its to balance for the horrible ICE engines
2019-01-22T12:57:00 < specing> the packs in most hybrids are really small though < 1kWh effective energy
2019-01-22T12:59:54 < zyp> jpa-, efficiency
2019-01-22T13:00:22 < jpa-> zyp: well yeah, better than fuel-only, but why not just put a plug on it?
2019-01-22T13:01:07 < zyp> even non-pluggable hybrids have a little efficiency gain, by regenerative braking and keeping the engine either off or in an efficient power band
2019-01-22T13:01:39 < specing> I don't understand why it is not yet mandated by law for all cars to be hybrids or better
2019-01-22T13:01:59 < zyp> in the prius solution, the entire transmission is electric
2019-01-22T13:02:04 < specing> jpa-: because those packs are constantly topped off by the built-in charger

2019-01-22T13:02:33 < jpa-> specing: hm, true, not much to charge from grid
2019-01-22T13:02:40 < specing> There would be no gain if you would charge already charged packs
2019-01-22T13:02:46 < zyp> engine->generator->inverter->motor->wheels, the entire variable transmission thing is performed by the inverter, there's no changing gears
2019-01-22T13:03:21 < zyp> (that's simplifying, there's also a mechanical connection and some differentials, and stuff)
2019-01-22T13:04:47 < specing> and in small EVs the motor, inverter and generator cost more than the battery

2019-01-22T13:05:24 < specing> I looked at the DIY EV market and the inverters and motors start north of $3k each
2019-01-22T13:05:40 < zyp> specing, I don't think regulating technologies are that useful, regulating results makes more sense
2019-01-22T13:05:50 < zyp> i.e. emissions
2019-01-22T13:06:09 < specing> most people seem to build DIY EVs from used forklift DC motors that can be had for <$300
2019-01-22T13:06:19 < zyp> if hybrid is the way to go to limit emissions, everybody will be pushed there anyway
2019-01-22T13:06:30 < specing> zyp: that works if the tests (1) aren't flawed (2) limits are ambitious
2019-01-22T13:06:37 < zyp> yeah
2019-01-22T13:06:37 < specing> they are neither (1) nor (2)
2019-01-22T13:06:48 < zyp> idk, isn't WLTP fairly decent?
2019-01-22T13:07:01 < specing> and "all cars have to be at least hybrids" is much easier to test for
2019-01-22T13:07:15 < specing> zyp: yes but see (2)
2019-01-22T13:07:24 < zyp> nah, then you have to define what is a hybrid, and makers will do the minimum to qualify
2019-01-22T13:07:39 < specing> China is on the right track with the 8% electric rule
2019-01-22T13:07:58 < zyp> ha, 8% electric :)
2019-01-22T13:08:23 < specing> yeah no idea how they'll do it, but I heard western exporters to China got into panic
2019-01-22T13:09:04 < specing> zyp: isn't it 10% this year already?
2019-01-22T13:09:13 < specing> zyp: its a rule that increases % each year or some such
2019-01-22T13:09:36 < zyp> % of what? new car sales?
2019-01-22T13:09:39 < PeterM> specing really? iirc stuff like front cuts of nissan leafs are pretty cheap
2019-01-22T13:09:44 < specing> zyp: y
2019-01-22T13:09:58 < specing> PeterM: "front cuts"???
2019-01-22T13:10:04 < zyp> 8% is cute
2019-01-22T13:10:27 < zyp> people are saying that norway might hit 50% this year
2019-01-22T13:10:51 < PeterM> front cut - the car is cut in half infront of the b pilar, and you get the front half of the car, ie the important bits, often used for wrecks or imported vehicles
2019-01-22T13:11:01 < specing> yeah but (1) GDP per capita in norway is like 10x of that in China  (2) China is damn huge
2019-01-22T13:11:04 < zyp> I think we're approaching 8% of all cars being electric, not just new cars
2019-01-22T13:11:43 < zyp> and yeah yeah, absolute numbers vs relative numbers, I know :)
2019-01-22T13:12:18 < specing> but this is interesting as it puts pressure off governemnt (to subsidize EVs) and onto automakers
2019-01-22T13:12:43 < zyp> I'm wondering how long the norwegian subsides will last
2019-01-22T13:12:49 < specing> so the latter will be forced to make cheap EVs that people will actually buy, or they wont be able to sell ICEs
2019-01-22T13:13:31 < specing> there are no direct subsidies in Norway, just waivers on VAT and others and 100+% tax on ICEs
2019-01-22T13:14:01 < specing> they aren't buying EVs because they'd be cheaper than ICEs, they are buying EVs because the ICEs are taxed to the sky
2019-01-22T13:14:39 < zyp> the end result is what matters, not how you massage the numbers to get there
2019-01-22T13:14:46 < specing> yes
2019-01-22T13:15:20 < zyp> VAT and car taxes were a thing before they wanted to make people buy EVs, so an exempt is a subside
2019-01-22T13:15:45 < zyp> also free parking, free ferries, free road tolls, etc…
2019-01-22T13:15:52 < zyp> those are starting to go away however
2019-01-22T13:16:20 < specing> yes, but it is not a direct subsidy
2019-01-22T13:16:30 < zyp> haven't claimed so either :)

2019-01-22T13:19:47 < zyp> EV benefits have probably saved me on the order of 8-10k EUR so far, including the VAT and stuff
2019-01-22T13:19:56 < PeterM> yeah, new stuff is pricey, but the same applies to ICE new stuff.
2019-01-22T13:20:11 < specing> the single highest road block to having your own DIY EV is that you can't get it registered
2019-01-22T13:20:15 < zyp> the simple fact that electricity is cheaper than gasoline have probably saved me 5-6k EUR
2019-01-22T13:20:40 < PeterM> also, inverters aren't that pricey, iirc there are a few decent opensource ones good to 300kw that are like $2k
2019-01-22T13:21:01 < zyp> by the time the car is five years old, not having to buy gasoline should have saved me more than anything else combined

2019-01-22T13:23:00 < zyp> last I heard it was varying in the 14-17 NOK range
2019-01-22T13:25:22 < specing> How much is that in euros?
2019-01-22T13:25:49 < zyp> move the dot over one digit, roughly
2019-01-22T13:26:05 < specing> thats not that expensive then
2019-01-22T13:26:14 < specing> it is 1.3 eur here
2019-01-22T13:26:35 < zyp> how much is electricity per kwh?
2019-01-22T13:27:12 < specing> 0.04 - 0.07 raw,  0.14 - 0.17 with taxes if you monthly use is cca 300kWh
2019-01-22T13:29:03 < zyp> heh
2019-01-22T13:29:17 < zyp> last year I didn't use less than 1000 kWh any single month :p
2019-01-22T13:30:40 < zyp> seems electricity is around 0.13 here now, including taxes
2019-01-22T13:30:57 < zyp> but I've seen it at 0.07 too
2019-01-22T13:31:14 < zyp> it's generally more expensive in the winter, naturally
2019-01-22T13:35:26 < specing> zyp: did you factor in static costs?
2019-01-22T13:36:48 < zyp> no, just marginal costs per kWh

2019-01-22T13:37:48 < specing> at 1MWh monthly probably not
2019-01-22T13:38:08 < specing> but at 300kWh it is 20-30% of the bill
2019-01-22T13:38:29 < zyp> if we start comparing that, we also have to factor in what you pay to have your gas line, that I save since I only have electricity, electric heating, electric cooking and so on
2019-01-22T13:38:56 < specing> true, even more static costs there

2019-01-22T14:06:01 < PeterM> RH is usually absolute humidity + some temperature math right? maybe its temp sensor is off?
2019-01-22T14:06:32 < Lux> no rh comes directly from the sensor
2019-01-22T14:06:56 < Lux> dew point and abs humidity needs some calc

2019-01-22T14:09:59 < qyx> giving false results
2019-01-22T14:10:28 < qyx> Si7021 has a heater inside to get rid of the condensed water apparently
2019-01-22T14:23:32 < Cracki> 111% sounds like oversaturation, i.e. condensed :D

2019-01-22T17:15:05 < dongs> some jap in comments complained about slow speeds too
2019-01-22T17:15:42 < PeterM> yeah that is true dongs, but at the same time i feel like they could have shitloads of garbage pcs to run skidmark on
2019-01-22T17:15:58 < dongs> get one of those buttcoin miner boards
2019-01-22T17:16:00 < dongs> with 20 pcie slots
2019-01-22T17:16:04 < dongs> then you can buttmark 20 at a time
2019-01-22T17:16:17 < rajkosto> you cant, buttmark is fullscreen only
2019-01-22T17:16:29 < rajkosto> 1x pcie is also oof

2019-01-22T18:41:52 < rajkosto> anything makefile based has a really hard time with spaces in paths
2019-01-22T18:41:57 < PaulFertser> dongs: but is it true? OpenOCD uses autoconf and I think it builds just fine from a directory with spaces.
2019-01-22T18:41:59 < rajkosto> because they use space as the "list delimiter" in string comprehension
2019-01-22T18:42:17 < rajkosto> it only works if no absolute paths are used in the makefile
2019-01-22T18:43:25 < PaulFertser> rajkosto: but why one would use absolute paths there?
2019-01-22T18:43:30 < rajkosto> sometimes you gotta
2019-01-22T18:43:39 < rajkosto> you generate an absolute path in the makefile then use it
2019-01-22T18:43:43 < rajkosto> instead of trying to be relative all the time

2019-01-22T18:59:13 < dongs> and take the .step model
2019-01-22T18:59:17 < dongs> you dont need that text etched on it
2019-01-22T18:59:20 < rajkosto> it doesnt have cool ST marking

2019-01-22T19:00:39 < rajkosto> most users upload step as well
2019-01-22T19:00:52 < dongs> even 3dcucktentcentral offers automatic online converter

2019-01-22T19:10:07 < dongs> how did you do that
2019-01-22T19:10:08 < rajkosto> it always aligns to some vertex

2019-01-22T19:11:02 < zyp> PaulFertser, does it also run correctly from a directory with spaces? :)
2019-01-22T19:11:34 < zyp> dongs, just the standard alignment tools
2019-01-22T19:12:05 < zyp> first click a face that's level with the board surface, then click a point and match it up with a point in the footprint

2019-01-22T19:16:14 < dongs> why wouldnt it
2019-01-22T19:16:15 < zyp> depends on the part
2019-01-22T19:16:16 < dongs> 12, 25 also works
2019-01-22T19:16:20 < rajkosto> doesnt it have a bootloader that only works when its 8

2019-01-22T19:17:16 < dongs> it runs off hsi
2019-01-22T19:17:31 < zyp> IIRC HSE range is 4-26, and either way you divide it down to 1 MHz before feeding it to the PLL
2019-01-22T19:17:45 < zyp> so it doesn't really matter
2019-01-22T19:17:56 < dongs> only F3/F4 use external xtal for USB DFU shit
2019-01-22T19:18:13 < zyp> other parts with the simpler PLL block without the input divider might be more picky
2019-01-22T19:18:29 < zyp> so if you're doing F0/F1/F3 double check the clock tree

2019-01-22T19:18:56 < dongs> The external oscillator frequency ranges from:
2019-01-22T19:18:56 < dongs> ● 4 to 16 MHz on STM32F101xx, STM32F102xx and STM32F103xx devices
2019-01-22T19:18:56 < dongs> ● 4 to 24 MHz for STM32F100xx value line devices
2019-01-22T19:18:57 < dongs> ● 3 to 25 MHz on connectivity line devices
2019-01-22T19:19:06 < dongs> looks like 12 max for you
2019-01-22T19:19:16 < dongs> or 16

2019-01-22T19:28:51 < dongs> 5K? 8K?
2019-01-22T19:28:56 < rajkosto> why you need more than 1440p at 24"
2019-01-22T19:28:57 < rajkosto> eagle eyes
2019-01-22T19:29:03 < rajkosto> retina burning display
2019-01-22T19:29:05 < dongs> rajkosto: my 13" laptop is 4K
2019-01-22T19:29:07 < dongs> kthx
2019-01-22T19:29:19 < dongs> i need all those pixels to see shitty code im writing
2019-01-22T19:29:28 < PaulFertser> dongs: I've created an issue instead: https://github.com/msteveb/autosetup/issues/43
2019-01-22T19:29:30 < qyx> my is 1366x768 \o/
2019-01-22T19:29:42 < zyp> idk, I just figure I don't really see a point in replacing my current monitor yet
2019-01-22T19:30:01 < dongs> PaulFertser: in what? autoconf?
2019-01-22T19:30:16 < zyp> and considering resolutions have just been increasing so far, why would they stop at 4k?
2019-01-22T19:30:19 < PaulFertser> dongs: no, the bug is in autosetup (some alternative to autoconf)
2019-01-22T19:30:30 < dongs> ah i see
2019-01-22T19:30:40 < dongs> god damn opensores.
2019-01-22T19:30:50 < zyp> haha
2019-01-22T19:30:51 < dongs> why the fuck is tehre more than one "autoconf"
2019-01-22T19:30:58 < dongs> why not fix the bugs in existing one???
2019-01-22T19:31:04 < dongs> instead of making a new one with MORE bugs
2019-01-22T19:31:08 < dongs> this shit never makes sense
2019-01-22T19:31:15 < aandrew> PaulFertser: ftdi_layout_signal foo -ndata 0x0600 means that when openocd wants to set foo 1, it will clear CBUS5 and CBUS6? 
2019-01-22T19:31:21 < PaulFertser> dongs: because different tools have different usecases, different tradeoffs.
2019-01-22T19:31:29 < dongs> yeah they all ahve tradeoffs
2019-01-22T19:31:31 < dongs> they run on lunix
2019-01-22T19:31:49 < PaulFertser> aandrew: yes, it looks like that
2019-01-22T19:32:36 < aandrew> ok, I thought I understood but but staring at it I start to doubt myself
2019-01-22T19:33:16 < PaulFertser> aandrew: hm, I'm not so sure actually, I usually open ft232h datasheet when I look at those values.
2019-01-22T19:34:09 < PaulFertser> aandrew: so no, 0x0600 means ACBUS1 + ACBUS2
2019-01-22T19:34:57 < PaulFertser> dongs: what's your favourite build system?
2019-01-22T19:35:26 < dongs> PaulFertser: visualstudio.exe
2019-01-22T19:35:43 < PaulFertser> dongs: building firmware projects with it?
2019-01-22T19:36:22 < aandrew> PaulFertser: hm. 0x6000 is what i want I guess
2019-01-22T19:36:25 < dongs> i could be if i wanted to, with visualdgb or wahetver. for that i use keil
2019-01-22T19:36:39 < rajkosto> use GNU ARM Eclipse ;)
2019-01-22T19:36:46 < aandrew> oh fuck I wrote 0x6000 in the config file 0x0600 here
2019-01-22T19:36:48 < aandrew> hah
2019-01-22T19:36:53 < PaulFertser> aandrew: not for 5 and 6, no :) 0x3000
2019-01-22T19:36:59 < aandrew> what?
2019-01-22T19:37:08 < aandrew> H5 and H6 are C5 and C6
2019-01-22T19:37:11 < PaulFertser> Oh sorry, I can't count
2019-01-22T19:37:20 < aandrew> oh good, I thought it was me
2019-01-22T19:37:41 < aandrew> ACBUS seems to map directly to GPIOH, and DBUS high bits are low 4 bits
2019-01-22T19:37:42 < PaulFertser> I got confused by presence of CBUS8 and 9.
2019-01-22T19:37:54 < aandrew> right there is no 8 and 9 on 2232
2019-01-22T19:37:58 < zyp> dongs, alternatively «that tool is shit, let's make a non-shit alternative», and then you end up with another shitty tool
2019-01-22T19:37:59 < aandrew> ok good
2019-01-22T19:38:11 < dongs> zyp, well yeah
2019-01-22T19:38:19 < dongs> cue in cmake
2019-01-22T19:38:21 < dongs> and similar garbage

2019-01-22T19:38:31 < dongs> its like

2019-01-22T19:48:31 < dongs> peopel pay for FPGA tools too
2019-01-22T19:48:36 < dongs> and it uses tcl

2019-01-22T20:56:23 < rajkosto> do i need to do something to TAMPER-RTC if i want the RTC to work
2019-01-22T20:56:37 < zyp> no
2019-01-22T20:56:54 < zyp> the tamper input is meant for when you have a tamper switch in your enclosure
2019-01-22T20:57:13 < zyp> if you do, the RTC can detect and store when the enclosure was opened
2019-01-22T20:57:28 < zyp> even when the rest of the system is sleeping

2019-01-22T23:46:13 < rajkosto> boot0 is useful cuz uart bootloader
2019-01-22T23:48:26 < englishman> ArrowOL
2019-01-22T23:48:31 < rajkosto> what even is "Embedded SRAM"
2019-01-22T23:48:42 < englishman> sram that is embedded
2019-01-22T23:49:18 < rajkosto> isnt there only 4K of that
2019-01-22T23:49:38 < malinus> rajkosto: embedded into the die?
2019-01-22T23:49:42 < englishman> without any context to that question, no, trillions of kilobytes are produced every year
2019-01-22T23:50:09 < specing> billions of megabytes
2019-01-22T23:50:15 < malinus> embedded SRAM = SRAM inside a IC
2019-01-22T23:50:16 < rajkosto> on a common stm32, when boot1 and boot0 are 1
2019-01-22T23:52:47 < rajkosto> 0, X is normal flash, 1, 0 is ROM bootloader, 1, 1 is for what
2019-01-22T23:52:54 < qyx> then it boots from the embedded sram
2019-01-22T23:53:33 < rajkosto> is it for something like FX2 reenumeration with USB-uploaded firmware ?
2019-01-22T23:54:35 < qyx> I don't use this mode, but idk how are you reasoning
2019-01-22T23:54:40 < qyx> you just place anything in the sram
2019-01-22T23:54:57 < qyx> and then I assume it boots from 0x20000000 after reset
2019-01-22T23:55:11 < qyx> at least thats how I understand it
2019-01-22T23:55:18 < rajkosto> yeah but you could only place code into the sram with code running on the stm32
2019-01-22T23:55:26 < qyx> why so
2019-01-22T23:55:37 < qyx> you have swd
2019-01-22T23:56:01 < rajkosto> cant swd reboot it from any address anyway
2019-01-22T23:56:09 < rajkosto> dont need external pin
2019-01-22T23:56:54 < qyx> I did never need this mode, maybe the guys at ST had some usecase for it

2019-01-23T00:25:34 < englishman> sounds correct
2019-01-23T00:26:22 < rajkosto> (ofc you can always just not have the bjt there but then you cant reenumerate usb from firmware)
2019-01-23T00:27:07 < englishman> also there is no usb bootloader unless you write your own
2019-01-23T00:29:06 < rajkosto> isnt there an additional thing needed for usb wake from standby

2019-01-23T01:14:40 < aandrew> there's no marker?
2019-01-23T01:15:16 < rajkosto> the top protrusions is what prevent wrongful insertion
2019-01-23T01:17:34 < karlp> (you can also just set the d+ line to gpio and toggle high/low yourself...)
2019-01-23T01:17:42 < karlp> (it's ... kinda hacky, but works pretty well)
2019-01-23T01:18:01 < rajkosto> that lets you renumerate properly ?

2019-01-23T01:18:37 < karlp> works good.
2019-01-23T01:19:00 < rajkosto> great, saves space
2019-01-23T01:19:12 < rajkosto> so only hardcoded 1.5k resistor needed on D+ to 3.3v
2019-01-23T01:19:23 < karlp> you may wish to experiment if it meets _your_ desires, but yeah, works well.
2019-01-23T01:19:47 < karlp> just bear in mind that you will then _always_ be detected instantly, you just have the option to force re-enum
2019-01-23T01:19:56 < rajkosto> is the flash boot/reset time long enough to trigger a false unknown device ?

2019-01-23T01:25:11 < Rickta59> any nucleo board is a better pick * aside from the nucelo-f103
2019-01-23T01:25:15 < rajkosto> bluepills are only supposed to be used on breadboards
2019-01-23T01:25:21 < mawk> that's not the same form factor nor price

2019-01-23T01:26:46 < karlp> nucleo32 exists mawk, just for starters
2019-01-23T01:26:58 < karlp> the continued swarm of people buying bluepills is why they keep gettting fucking made.

2019-01-23T01:29:23 < rajkosto> i use them in full jtag mode, all the pins are there
2019-01-23T01:29:27 < mawk> but nucleo is expensive and big
2019-01-23T01:29:33 < mawk> the smallest nucleo may be fine
2019-01-23T01:29:34 < karlp> you really think having a spiderweb of wires is a "nice" experience?
2019-01-23T01:29:37 < Rickta59> expensive ?
2019-01-23T01:29:42 < karlp> mawk I said nucleo32 and no, it' snot expensive
2019-01-23T01:29:50 < karlp> if you're using blue pills as products, you're on your own
2019-01-23T01:29:58 < karlp> if you're not, nucleo32s are perfectly cheap enoughh
2019-01-23T01:30:25 < mawk> 10€ vs 1.7€ is expensive
2019-01-23T01:30:37 < Rickta59> how many are you going to buy mawk ?
2019-01-23T01:30:43 < rajkosto> for 10e get a bluepill and your own custom pcb for it
2019-01-23T01:30:47 < mawk> I'm not buying them, I'm just wondering
2019-01-23T01:30:57 < rajkosto> then transplant all the components over ;)
2019-01-23T01:30:58 < Rickta59> well if you aren't buying thousands who cares
2019-01-23T01:31:34 < mawk> I have some nucleos but it was expensive yes
2019-01-23T01:31:36 < mawk> I'm not rich
2019-01-23T01:31:41 < mawk> maybe you don't care
2019-01-23T01:32:00 < Rickta59> electronics is a rich persons game
2019-01-23T01:32:02 < mawk> I'm sure that's partly why people keep buying the blue pill thing
2019-01-23T01:32:25 < mawk> I bought my scope on the french craiglist from an university laboratory
2019-01-23T01:32:36 < rajkosto> its cuz you search for stm32 on ebay or aliexpress and get bluepills
2019-01-23T01:32:42 < mawk> lol
2019-01-23T01:32:49 < mawk> no I got a nucleo before anything
2019-01-23T01:32:55 < Rickta59> which one?
2019-01-23T01:33:02 < mawk> like, the evening after my first stm32 class at school I thought it was so cool that I had to buy one
2019-01-23T01:33:03 < mawk> stm32L1
2019-01-23T01:33:12 < mawk> L152RE, nucleo 64
2019-01-23T01:35:33 < Rickta59> aside from the speed that seems reasonable
2019-01-23T01:35:43 < mawk> it was almost the cheapest
2019-01-23T01:35:47 < mawk> also low power sounded nice to try
2019-01-23T01:36:39 < specing> > some nucleos but it was expensive 
2019-01-23T01:37:03 < specing> stm32 disco/nucleo kits are probably the cheapest way to start embedded development
2019-01-23T01:37:11 < karlp> it's hhow people got into stm32s.
2019-01-23T01:37:16 < karlp> certainly how I did.
2019-01-23T01:37:29 < Rickta59> i got a bunch of free discovery boards back 5 years ago
2019-01-23T01:37:37 < Rickta59> they were just sending them to anyone who asked
2019-01-23T01:38:24 < Rickta59> you don't need more than 2 boards
2019-01-23T01:38:43 < Rickta59> otherwise you get distracted

2019-01-23T01:42:27 < emeb> Rickta59: well, I've been doing stm32 dev for nigh on 10 yrs now, so I've got months on some of them and at least a few hours on most.
2019-01-23T01:42:52 < emeb> but there are a few that have only been used once.
2019-01-23T01:43:07 < Rickta59> but admit it ... mostly they sit in a box under your desk feeling like a childhood teddy bear

2019-01-23T01:43:36 < aandrew> lol
2019-01-23T01:43:44 < emeb> Mostly I just use the st-link on one of them.
2019-01-23T01:44:39 < emeb> but given that most of them cost about $10 and I've spent at least an hour with them I'd consider that money well spent.
2019-01-23T01:44:42 < Rickta59> i wish i had focused on the stm32 stuff when i started .. i was mucking with all different processors for a couple of years before I decided to focus on the stm32
2019-01-23T01:44:58 < Rickta59> wasted a lot of time on ti crap
2019-01-23T01:45:04 < Rickta59> then nxp
2019-01-23T01:45:13 < emeb> same
2019-01-23T01:45:31 < emeb> did some actual paying work on dsPIC, but that petered out.
2019-01-23T01:45:57 < Rickta59> but to be honest the stm32 6 years ago when i first got one wasn't sorted on linux .. * I was focused on the m0 then
2019-01-23T01:46:09 < Rickta59> so swd wasn't really ready in openocd
2019-01-23T01:46:42 < emeb> openocd + st-link 2.1 + nucleo is pretty much bullet-proof now.
2019-01-23T01:47:01 < Rickta59> and ST kind of screwed them selves back then with thier goofy license on their headers
2019-01-23T01:47:01 < emeb> I used to use black magic probe more because it was more reliable than OOCD
2019-01-23T01:47:31 < Rickta59> yeah same here
2019-01-23T01:47:37 < Rickta59> but yes now there is no reason
2019-01-23T01:47:41 < emeb> but lately BMP seems to lag on new silicon
2019-01-23T01:48:10 < Rickta59> seems to work well with stm32f1 :)
2019-01-23T01:48:13 < emeb> I was doing some heavy F7 dev about 1.5 yrs ago and BMP didn't support it yet, so OOCD was the only way.

2019-01-23T01:49:03 < Rickta59> but honestly the best advice i can say is just get a nucleo board, with say an L4 on it and just focus on that, it will keep you learning for a long time 
2019-01-23T01:49:07 < aandrew> I haven't used bmp yet, just jlink for everything
2019-01-23T01:49:13 < mawk> I don't understand this graphic, I'm supposed to release CE when talking to the MRF24J40 ?

2019-01-23T02:07:37 < emeb> englishman: I've been using Zynq parts for the last 1+ year, so technically I guess the answer is yes.
2019-01-23T02:07:57 < emeb> but I haven't really studied the resources in the I/O very closely.
2019-01-23T02:07:59 < emeb> why?
2019-01-23T02:08:12 < englishman> lvds
2019-01-23T02:08:27 < emeb> Yeah, used that some.
2019-01-23T02:10:36 < englishman> cool
2019-01-23T02:11:01 < emeb> basic differential stuff w/ some on-chip termination options.
2019-01-23T02:11:15 < englishman> yeah seems handy. and a lot of them
2019-01-23T02:14:25 < emeb> I did a huge Virtex 5 board with 2 95T parts that had a giant LVDS bus between them running @ 125MHz. Worked fine.
2019-01-23T02:15:55 < emeb> Same system had some 250MHz ADCs w/ LVDS outputs driving one of the V5 parts. Never had any issues w/ signal integrity. Did have to fiddle a bit with clock / data timing to get reliable data, but once I had it figured out it was fine thereafter.
2019-01-23T02:16:45 < emeb> That wasn't SelectIO, but V5 equivalent - not a whole lot of difference.

2019-01-23T02:24:08 < englishman> cool, doing both tx and rx
2019-01-23T02:26:18 < emeb> yeah. fun thing about that is if you control both ends then routing options open up - you can reverse polarity on one end to help routing if you know it and then invert the signal inside the FPGA.
2019-01-23T02:26:57 < emeb> That's a big help when you're running hundreds of pairs across a 10L board.
2019-01-23T02:27:18 < englishman> no kidding. with zero clock skew
2019-01-23T02:27:28 < englishman> sony is pushing this SLVS-EC thing hard and I can totally see why

2019-01-23T11:06:41 < kakimir> bottom gnd
2019-01-23T11:06:44 < kakimir> then signal?
2019-01-23T11:07:00 < kakimir> then vcc and then top signal / components layer?
2019-01-23T11:07:48 < kakimir> top layer won't have copper fill
2019-01-23T11:07:51 < kakimir> maybe
2019-01-23T11:10:15 < Haohmaru> i recently found some nice pdf that suggests a few things with explanations
2019-01-23T11:12:29 < Haohmaru> kakimir this: https://docs.toradex.com/102492-layout-design-guide.pdf
2019-01-23T11:12:59 < Haohmaru> oh wait, are you doing 2-layer?
2019-01-23T11:14:03 < kakimir> 4
2019-01-23T11:16:16 < Haohmaru> okay, you might find useful things in that document (i do, coz i'm a n00b)
2019-01-23T11:17:41 < Haohmaru> from what i read, a typical organization of the layers is, top-to-bottom: fast signals | gnd | power rails | slower signals
2019-01-23T11:23:06 < Haohmaru> it also gives examples of wrong and less-wrong things, and talks about why that is so
2019-01-23T11:42:09 < kakimir> I'm going to do my way

2019-01-23T11:49:38 < Haohmaru> no worries, he gon' innovate
2019-01-23T11:52:33 < karlp> not really sure where in that doc you're seeing "wrong" layer stacks
2019-01-23T11:53:37 < Haohmaru> no, there are examples of bad/gud track routing, component arangement, feng-shui, etc..
2019-01-23T11:54:13 < karlp> thought kaks was only looking at layer stackups.
2019-01-23T11:54:26 < karlp> you can't advise him on anything else, he'll just ignore you and add SMAs anyway
2019-01-23T11:54:30 < Haohmaru> karlp as long as the information in that document isn't wrong, then it is very useful to me, since i'm not even an engineer
2019-01-23T11:54:45 < Haohmaru> what's this SMA thing?
2019-01-23T11:54:55 < Haohmaru> is it wifi antenas?
2019-01-23T11:55:10 < Haohmaru> or SMA diodes
2019-01-23T11:58:07 < Haohmaru> anyway, after briefly reading thru that document, i realized that perhaps when i copy/paste an example schematic from a datasheet or demoboard, some of the passive components in it are maybe there due to the PCB layout, so i shouldn't just copy them in the schematic and place them anywhere.. but this is typically not explained in the documents
2019-01-23T11:59:12 < Haohmaru> like, it says that you should have stuff like "stitching capacitors"
2019-01-23T11:59:49 < Haohmaru> i didn't know about this at all before, and i guess some of the weird 10nF caps i've previously copy-pasted might have been exactly that
2019-01-23T12:00:02 < Haohmaru> i don't even know where i've placed them on the boards x_x
2019-01-23T12:01:06 < Haohmaru> probably in some dumb corner *shrug*
2019-01-23T12:05:23 < Haohmaru> altho, some of the more "complex" boards have been 4-layer ones, where i've used 2-layer for my version, so things change anywayz
2019-01-23T12:06:11 < Haohmaru> still, for a nub guy like me, this document is useful, i thought someone else might also find it useful
2019-01-23T12:06:54 < Haohmaru> i just recently began working on my first 4-layer project, but it's currently frozen

2019-01-23T12:37:00 < zyp> kakimir, simple 4L designs are signal on outer, gnd/power on inner, it doesn't matter too much which is ground and which is power for simple stuff
2019-01-23T12:37:51 < zyp> when you start doing transmission line calculations on signals, you want a ground directly adjacent to them
2019-01-23T12:39:44 < zyp> when I do semi-complex 4L stuff, I tend to do fanout on top and routing on bottom, in which case it'd make sense to put the ground on the inner bottom layer since that's what the signal will travel adjacent to for the most part
2019-01-23T12:40:46 < Haohmaru> i keep forgetting what this "fanout" thing means
2019-01-23T12:41:21 < zyp> signals "fanning out" from chip pin to vias
2019-01-23T12:41:31 < zyp> chip pads to vias*
2019-01-23T12:42:44 < Haohmaru> that's when you don't run tracks on that same layer but immediately send the signal from the pin to a different layer? or is it also called that way in general when switching to another layer?

2019-01-23T12:45:28 < zyp> Haohmaru, I think the term is generally used for larger chips in more complex designs, where it's not possible to route everything in one layer anyway :)
2019-01-23T12:46:13 < zyp> BGA chips, you generally can't route out in only one layer
2019-01-23T12:46:50 -!- R2COM [~R2COM@ip68-3-184-221.ph.ph.cox.net] has quit []
2019-01-23T12:47:00 < Haohmaru> i guess you mean that thing.. i've seen it on some boards, where (for example) the top layer mostly has only horizontal tracks, while the bottom layer mostly only vertical ones
2019-01-23T12:47:30 < Haohmaru> or maybe not
2019-01-23T12:48:08 < zyp> nah, that sounds dumb
2019-01-23T12:48:19 < Haohmaru> oh, i think i know.. it's when you put smd components on the top, and then try to leave the bottom layer free so you can have just tracks there
2019-01-23T12:48:57 < zyp> that's unrelated to fanning out, but that's a reasonable design strategy
2019-01-23T12:49:36 < Haohmaru> no was talking about your previous sentence about "when i do semi-complex 4-layer stuff"
2019-01-23T12:49:43 < zyp> yeah
2019-01-23T12:49:50 < zyp> https://bin.jvnv.net/file/ScDxl.png <- here's an example
2019-01-23T12:50:21 < Haohmaru> yeah, no blue cmponentz
2019-01-23T12:50:33 < zyp> it's not super dense, but you see how all the long traces run on the bottom
2019-01-23T12:51:06 < Ecco> Haohmaru: hopefully :-D
2019-01-23T12:52:45 < karlp> vertical on one, horizontal on another was somethign I was advised years and years ago as a routing approach, it's not for any science though.
2019-01-23T12:53:19 < zyp> vertical on one, horizontal on another sounds old and outdated to me
2019-01-23T12:53:30 < Ecco> really? I'd say it's a great start
2019-01-23T12:54:05 < Haohmaru> maybe it's a simple naive rule for noobs who have absolutely no idea how to start routing?
2019-01-23T12:54:29 < Haohmaru> in the beginning, i had no idea wtf i'm doing and i was often getting stuck very soon in the layout
2019-01-23T12:54:33 < zyp> yeah, and it probably made more sense before everything became so integrated
2019-01-23T12:55:12 < zyp> today you typicall have a central chip that like 90% of your signals goes to/from
2019-01-23T12:55:32 < Haohmaru> i know a one or two old folks who have routed PCBs with tape on a huge table.. x_x
2019-01-23T12:56:30 < zyp> https://bin.jvnv.net/file/Jvtp0.png <- here's another design I did once
2019-01-23T12:56:42 < zyp> bit denser than the previous
2019-01-23T12:56:43 < karlp> yeah, this was in mostly throughhole designs
2019-01-23T12:56:54 < karlp> and with much fatter minimum traces
2019-01-23T12:57:27 < karlp> it's completley bogus for anything that' slike an stm32 with things on it, as it's all on one side in one node, like zyp said
2019-01-23T12:57:53 < zyp> you also wanna avoid vias
2019-01-23T12:58:27 < Haohmaru> yeah
2019-01-23T12:58:33 < zyp> my rule of thumb when routing is that a signal should at most have two vias; one to get from the source part to the routing layer and one to get from the routing layer to the target part
2019-01-23T12:59:06 < zyp> it's not always possible (or even desireable), but it gets you a pretty good starting point
2019-01-23T12:59:07 < Haohmaru> that document i'm reading says the same thing too
2019-01-23T12:59:51 < zyp> and then you have some signals that are not just point to point, they might naturally have more vias

2019-01-23T13:00:26 < Haohmaru> when i started, i knew that the number of vias should be kept as small as possible, but i didn't know why.. i thought that maybe they affect the PCB fab price
2019-01-23T13:00:44 < zyp> well, there's two reasons
2019-01-23T13:00:52 < zyp> one is that they affect signal integrity
2019-01-23T13:01:07 < zyp> and the other is that they are simply big, they consume a bunch of area on all layers
2019-01-23T13:08:53 < karlp> vias are just 90degree bends,
2019-01-23T13:08:57 < karlp> they're not the devil
2019-01-23T13:11:21 < Haohmaru> https://i.imgur.com/bLDocds.png
2019-01-23T13:16:30 < zyp> they are also impedance incontinuities since they depart from the reference layer
2019-01-23T13:16:54 < zyp> not that it matters much for normal stuff
2019-01-23T13:18:01 < zyp> Haohmaru, you should also consider DFM
2019-01-23T13:18:14 < Haohmaru> dee-eff-wat
2019-01-23T13:18:45 < zyp> only having parts on top means PTH parts can be cheaply wave soldered
2019-01-23T13:19:01 < Haohmaru> design for.. manufacturing?
2019-01-23T13:19:03 < zyp> if you have SMT parts on bottom, they need special considerations
2019-01-23T13:19:14 < zyp> manufacturability
2019-01-23T13:19:55 < zyp> in this context, design it so it's cheap to solder
2019-01-23T13:20:14 < Haohmaru> i solder these myself still
2019-01-23T13:20:22 < Haohmaru> with le iron
2019-01-23T13:21:16 < Haohmaru> but yeah i wasn't gonna manage to make it small if i had to put parts only on certain sides
2019-01-23T13:21:26 < Haohmaru> and it was important for it to be small
2019-01-23T13:21:43 < zyp> yeah, but the way is short, one day you might find out other people would be interested in your shit too, enough to make a 100-batch of stuff, and then you've got the ball rolling
2019-01-23T13:21:46 < zyp> been there, done that
2019-01-23T13:21:59 < Haohmaru> now, my next project is reinventing this same module, with a cortex mcu, and 4-Layers
2019-01-23T13:22:14 < Haohmaru> and i have to make it smaller, or at least not bigger than the old one
2019-01-23T13:23:28 < Haohmaru> i don't even wanna think about that, luckily it's frozen at the moment
2019-01-23T13:23:44 < zyp> is this the ethernet thing?
2019-01-23T13:23:50 < Haohmaru> yez
2019-01-23T13:24:07 < zyp> IIRC you have plenty of area :p
2019-01-23T13:24:23 < zyp> what was the board dimensions again?
2019-01-23T13:24:35 < Haohmaru> 70x40mm, on that picture
2019-01-23T13:25:18 < karlp> fucking kill those hc49 crystals for a start
2019-01-23T13:25:23 < karlp> free realestate
2019-01-23T13:25:30 < karlp> and should be a bom price drop too
2019-01-23T13:26:02 < zyp> that 3x10 header thing looks pretty crazy
2019-01-23T13:26:14 < Haohmaru> yes, i switched to.. SMD 4pin crystals on the new project
2019-01-23T13:26:22 < zyp> at first I thought this was some RC servo thing
2019-01-23T13:26:23 < karlp> what's the second big qfp? or the first, I take it one of these is your xmega lovechild?
2019-01-23T13:26:32 < zyp> phy, I guess?
2019-01-23T13:27:01 < Haohmaru> the big one is the xmega, the smol one is teh wiznet w5000
2019-01-23T13:27:16 < Haohmaru> muh love
2019-01-23T13:27:17 < Haohmaru> ;P~
2019-01-23T13:27:55 < zyp> but still, 40x70 is huge
2019-01-23T13:28:24 < Haohmaru> well, the cortex is huge too
2019-01-23T13:29:06 < zyp> https://bin.jvnv.net/file/ScDxl.png <- IIRC this is 60x60-ish, and if you cut away the wire terminals, all the mess in the top left and move the vreg to the bottom left, it'd be plenty smaller than 40x70
2019-01-23T13:30:29 < Haohmaru> what footprint is that cortex?
2019-01-23T13:30:48 < zyp> qfp100
2019-01-23T13:31:06 < zyp> f407v IIRC
2019-01-23T13:32:01 < zyp> https://bin.jvnv.net/file/X0LvB.png <- here's another I did, I think this is about 40mm wide, probably longer than 70mm but you can cut off the stuff in the top and bottom that's not relevant to you
2019-01-23T13:33:07 < Haohmaru> i know it's probably pretty possible, but i got also some other things to deal with, and most importantly - i'm not a magician ;P~
2019-01-23T13:34:30 < Haohmaru> i might be allowed to make <whatever> board first (read, big) just for prototyping/testing while i develop the actual firmware, and then adjust the layout to make it smol
2019-01-23T13:35:26 < zyp> oh, btw, if you're making some sort of ethernet module, I advise throwing on some sort of serial flash on it, couple of megabytes or so :)
2019-01-23T13:35:28 < Haohmaru> at least this is one of the very few projects which has a fixed functionality
2019-01-23T13:35:41 < Haohmaru> what for?
2019-01-23T13:36:20 < zyp> it doesn't cost much area, and you'd wish you had when people later figure out they wanna serve up some files or shit over http
2019-01-23T13:36:33 < zyp> or receive firmware images or whatever
2019-01-23T13:37:02 < Haohmaru> people? who are them people?
2019-01-23T13:37:22 < zyp> whoever is gonna use this hardware in a project
2019-01-23T13:37:23 < Haohmaru> i'm the only "dev" guy here :/
2019-01-23T13:37:32 < Haohmaru> <---
2019-01-23T13:37:36 < Haohmaru> x_x
2019-01-23T13:37:42 < zyp> well, point still stands
2019-01-23T13:38:24 < Haohmaru> i've never poked my nose into anything bigger than 64KB eeprom, aren't these flash chips kinda huge
2019-01-23T13:38:45 < Haohmaru> like 10x10mm-ish
2019-01-23T13:39:02 < zyp> if people later come ask you for a fancy http ui, you can just make a javascript app that runs all in the browser and stuff it into that flash, and then just make a simple API for it to call
2019-01-23T13:39:12 < zyp> no need to do dynamic pages on the server side
2019-01-23T13:39:20 < Haohmaru> oh, i'm also allowed to use BGA for this, but i try to avoid it as much as possible
2019-01-23T13:39:45 < zyp> even if you don't have any plans for it now, keep in mind you're making a reusable module
2019-01-23T13:39:49 < karlp> what?! no, they're just so8 normally.
2019-01-23T13:39:56 < zyp> also, what karlp said
2019-01-23T13:40:08 < Haohmaru> i don't speak Java and i got no clue about webdev stuff
2019-01-23T13:40:11 < karlp> and that's if you want the big ones, you can get them in much smaller.
2019-01-23T13:40:30 < Haohmaru> hm
2019-01-23T13:40:57 < zyp> my point is, think about future needs, not current needs
2019-01-23T13:41:15 < Haohmaru> i can't
2019-01-23T13:41:20 < zyp> you don't want to redo the board design every time somebody asks for a new feature
2019-01-23T13:41:28 < Haohmaru> the boss decides
2019-01-23T13:41:55 < zyp> adding software to support new features is simple, adding hardware is not
2019-01-23T13:42:29 < Haohmaru> well, if it's a matter of inserting a SOIC8 chip with a few passives around it - i could just reserve an SPI? module on the brain chip and some area for the flash chip
2019-01-23T13:43:12 < zyp> as long as you're working with low volumes, trimming the hardware to the bare minimum does not make sense, that's what you do when you want to ship some thousands of units so that the cost optimization will pay for itself
2019-01-23T13:44:06 < Haohmaru> the boss makes those kinds of decisions
2019-01-23T13:44:36 < zyp> if you're already reserving space, just put down the footprint, and if boss doesn't let you buy the part for it, just leave it unpopulated :p
2019-01-23T13:44:56 < zyp> at least you don't have to refab the pcb when the need arrives
2019-01-23T13:46:02 < Haohmaru> well as i mentioned, it's quite likely that i will be allowed to make a bigger prototype board first
2019-01-23T13:47:03 < Haohmaru> i already have an SPI eeprom (altho, not in a SOIC8 footprint) for the ethernet mac address, so.. there will be time to decide what to do about such minor details
2019-01-23T13:47:47 < zyp> let me tell you from experience, when you don't get the features you might need into the design, you get to sit there and solder them into the design by hand later instead: https://bin.jvnv.net/file/6n9NM.jpg
2019-01-23T13:49:57 < Haohmaru> if you can see some of the PCBs behind my chair here, this on your picture is nothing
2019-01-23T13:50:01 < Haohmaru> ;P~
2019-01-23T13:50:15 < zyp> my point still stands :p
2019-01-23T13:50:19 < Haohmaru> i know
2019-01-23T13:50:46 < karlp> I'll also add that "leaving this spaces for things in the hardware" is ideal, but very hard to get right :)
2019-01-23T13:50:57 < Haohmaru> i try to explain the situation and options to the boss as much as i can, then he decides
2019-01-23T13:53:37 < zyp> karlp, yeah, one thing is trying to predict what you might need, another is actually guessing right
2019-01-23T13:54:26 < zyp> but I'm speaking from experience when I suggest that extra storage is useful for ethernet modules :)
2019-01-23T13:57:28 < karlp> indeed, as soon as you have ethernet it instantly becomes, "where's the webserver?"

2019-01-23T15:39:49 < kristoiv> Hello. Is there a way of software reseting the entire uC (including ALL registers for peripherals and arm cores).
2019-01-23T15:41:01 < kristoiv> Would, for example, a watchdog reset definitively reset everything?
2019-01-23T15:41:42 < zyp> SYSRESETREQ
2019-01-23T15:42:16 < zyp> a watchdog reset would also work, but is more roundabout
2019-01-23T15:42:23 < zyp> SYSRESETREQ is straight to the point
2019-01-23T15:43:52 < zyp> no global resets would however reset the backup domain, as the purpose of the backup domain is to survive system shutdown/restarts
2019-01-23T15:43:57 < jpa-> (even it will only reset stuff that NRST pin resets, i.e. it won't reset debug unit or RTC)
2019-01-23T15:44:32 < kristoiv> zyp, thanks for answering, isn't this just reseting the ARM core itself, or does it also reset peripherals?
2019-01-23T15:45:02 < zyp> it resets everything except backup domain

2019-01-23T15:45:32 < kristoiv> Any documentation on what the backup domain entails?

2019-01-23T15:45:50 < zyp> backup domain is mostly the RTC
2019-01-23T15:45:59 < zyp> also IWDG, I guess
2019-01-23T15:46:00 < kristoiv> zyp, okay.
2019-01-23T15:46:14 < zyp> and some parts have BACKUPSRAM
2019-01-23T15:46:34 < kristoiv> Our primary problem seen is random data in SPI buffers
2019-01-23T15:46:44 < kristoiv> On startup after reset
2019-01-23T15:47:05 < jpa-> i think sysresetreq resets IWDG unless it is enabled by option bytes
2019-01-23T15:47:41 < zyp> jpa-, might be, I haven't checked in detail
2019-01-23T15:47:51 < jpa-> me neither :)
2019-01-23T15:48:29 < zyp> kristoiv, random how and in which buffers?
2019-01-23T15:48:56 < zyp> does DR actually have a defined initial value?
2019-01-23T15:49:20 < zyp> or are we talking about ram buffers here? (for DMA or whatever)
2019-01-23T15:49:29 < kristoiv> zyp, We have a selfwritten bootloader (to upgrade over spi), after finishing and resetting the device it sends/receives invalid bytes (sometimes) that are left in the SPI peripheral buffers
2019-01-23T15:49:43 < jpa-> or perhaps you are changing SPI configuration when SPE bit is 1
2019-01-23T15:49:58 < jpa-> it causes STM32 SPI to go silly and do strange stuff like 13-bit transfers
2019-01-23T15:50:32 < zyp> are you sure you're seeing full bytes, not just random garbage that happens when the spi lines are released upon a reset?
2019-01-23T15:51:19 < zyp> are you doing SPI without a chip select?
2019-01-23T15:51:53 < kristoiv> Yes to chip select. No to changing configs while SPE
2019-01-23T15:51:54 < zyp> normally you'd want a chip select even in a situation with just a single slave, to handle synchronization and signal valid data
2019-01-23T15:52:26 < zyp> otherwise you risk every noise on the lines being processed as a valid clock

2019-01-23T19:21:41 < BrainDamage> and the space that gets cut doesn't go wasted
2019-01-23T19:21:57 < BrainDamage> typically you put there test circuits

2019-01-23T19:22:27 < karlp> test patterns I can see, but test circuits?

2019-01-23T19:24:17 < BrainDamage> you route outside some test pads and connect temporary contacts

2019-01-23T20:14:36 < rajkosto> does the RTC and SRAM still work ? i assume it does because there should be an internal switch that uses VDD for those instead of VBAT whenever VDD is present (to not waste battery power when VDD is on)
2019-01-23T20:32:54 < zygron_> rajkosto: iirc there is indeed an internal switch (at least on F4XX), and it's recommended to put a diode between the battery and VBAT so no current is injected into the battery when the cpu is powered on

2019-01-23T23:01:48 < specing> IBM begs to differ
2019-01-23T23:01:59 < Cracki> I do wonder... do y'all just point the hot air at the pins, or do you help it along by heating from below? don't mean big rework station... hotplate or heating element helps already
2019-01-23T23:02:36 < specing> I fixed my nvidia by heating it from above
2019-01-23T23:02:46 < Steffanx> "fixed"
2019-01-23T23:03:19 < specing> Steffanx: did so 20-30 times before giving up and buying a new used computer
2019-01-23T23:03:38 < Steffanx> Hah, see.
2019-01-23T23:03:53 < specing> it was NVidia on life support
2019-01-23T23:04:32 < specing> what was interesting is that the life time between reflows fell logarithmically until it settled at cca 1 week
2019-01-23T23:04:49 < Cracki> bake at 230 celsius for 10 minutes
2019-01-23T23:04:49 < rajkosto> didnt reflow good enouigh
2019-01-23T23:04:53 < rajkosto> should have added tons of flux
2019-01-23T23:05:11 < Cracki> porn studios order their "flux" by the barrel
2019-01-23T23:05:17 < specing> I wasn't reflowing at all, just heating it up
2019-01-23T23:05:30 < specing> the problem was iirc in the interposer, not pcb connection
2019-01-23T23:05:57 < Cracki> 9000-layer boards must be masters at conducting heat away from any spot
2019-01-23T23:09:30 < antto> dumb question: say i need to feed a circuit with 0.5A at 5V.. now if i use a regulator to generate those 5V, and the regulator itself runs on 10V - it will draw 0.25A from 10V?
2019-01-23T23:09:56 < rajkosto> what regulator
2019-01-23T23:10:38 < antto> one of those that doesn't just turn the excess voltage into boiling water
2019-01-23T23:11:01 < rajkosto> which one
2019-01-23T23:11:02 < rajkosto> chip
2019-01-23T23:11:16 < antto> well, i'm thinking of mc33063 maybe
2019-01-23T23:12:01 < rajkosto> 0.3125A from 10V
2019-01-23T23:12:09 < rajkosto> at 80% efficiency since its a buck/boost
2019-01-23T23:12:56 < antto> right, i was oversimplifying it as if efficiency == eggcelent

2019-01-23T23:23:43 < aandrew> mostly I just blast it from the top and be patient

2019-01-23T23:24:55 < Cracki> ic ic
2019-01-23T23:25:10 < aandrew> antto: if your load draws 0.5A at 5V that's 2.5W. The regulator itself will not be 100% efficient so you derate that by the efficiency at that load and recompute for your 10V incoming power
2019-01-23T23:25:35 < aandrew> Cracki: yes, I use it to reflow ICs. :-)
2019-01-23T23:26:25 < aandrew> antto: so 80% efficiency (taking rajkosto's number) would be 2.5W / 0.8 = 3.125W now that you're including the losses in the regulator
2019-01-23T23:26:37 < aandrew> 3.125W / 10V = 0.3125A from a 10V source
2019-01-23T23:27:31 < antto> i was thinking 0.5A * 5V/10V == 0.25A, 0.25A/0.8
2019-01-23T23:27:38 < antto> but i guess, same sh*t?
2019-01-23T23:27:59 < Cracki> maths the same but one has the power term explicitly
2019-01-23T23:28:05 < karlp> now you get to have fun calculating the heat rise
2019-01-23T23:28:43 < aandrew> heh
2019-01-23T23:28:57 < Cracki> mass, specific heat (right term?), time, ...
2019-01-23T23:28:58 < aandrew> I always struggle with theta-jc vs theta-ja
2019-01-23T23:29:34 < aandrew> so I think I figured out why my 125MHz clock isn't showing up
2019-01-23T23:30:45 < aandrew> the fet drivers (just using them because they're beefy) have no hope in hell of switching 125MHz
2019-01-23T23:30:49 < aandrew> 10MHz they are doing great

2019-01-23T23:31:30 < Cracki> so you want mosfets to toggle at 125 MHz... why?
2019-01-23T23:31:52 < Cracki> I think with beefier drivers, you might get further :>
2019-01-23T23:32:21 < aandrew> I don't
2019-01-23T23:32:23 < aandrew> at all
2019-01-23T23:32:29 < aandrew> I'm not driving mosfets with these
2019-01-23T23:32:36 < aandrew> I'm just driving MCX ports
2019-01-23T23:32:39 < Cracki> *headscratch*
2019-01-23T23:32:53 < Cracki> so the clock doesn't show up... but it isn't supposed to anyway?
2019-01-23T23:33:05 < aandrew> but I like using fet drivers for driving cables because they're also very capacitive and the fet drivers are robust
2019-01-23T23:33:06 < Cracki> ah!
2019-01-23T23:33:15 < Cracki> the drivers are just meant to drive mcx ports...
2019-01-23T23:33:19 < aandrew> yep
2019-01-23T23:33:35 < Cracki> ic, used as "line" driver
2019-01-23T23:33:44 < aandrew> I have differential clock --> DS90C402 (diff-to-se) --> MIC4126 --> MCX
2019-01-23T23:34:17 < aandrew> the DS90C402 is just "tapping" the LVDS line (the clock is really going to the ADC, where it's actually terminated)
2019-01-23T23:35:14 < Cracki> so what's different about mosfet drivers compared to other line drivers that makes them not output that clock...
2019-01-23T23:35:27 < aandrew> well this mosfet driver is jst too slow
2019-01-23T23:35:36 < aandrew> it's not meant to transmit sucha  fast signal
2019-01-23T23:35:53 < Cracki> hm! but it's meant to charge a gate quickly
2019-01-23T23:36:08 < Cracki> but not too often?
2019-01-23T23:36:32 < Cracki> could these things have lowpassed inputs maybe?
2019-01-23T23:36:48 < Cracki> MIC4126 you say
2019-01-23T23:36:51 < aandrew> they could be slewed yes
2019-01-23T23:36:56 < aandrew> yeah it's a nice strong driver
2019-01-23T23:36:59 < Cracki> now I'm curious
2019-01-23T23:37:13 < Cracki> zero mentions of "hz" in that sheet
2019-01-23T23:37:18 < aandrew> I do actually use them as fet drivers as well but this was more of a "hey I need to drive a capacitive load, I'm already using these!"
2019-01-23T23:37:29 < aandrew> correct, I just checked that beore starting this conversation too
2019-01-23T23:37:32 < Cracki> single mention of "slew" in relation to input characteristics
2019-01-23T23:37:43 < aandrew> there's rise/fall times
2019-01-23T23:37:54 < aandrew> but I suspect that's more about driving capacitors
2019-01-23T23:37:56 < Cracki> 20 ns, that would (not) do it
2019-01-23T23:38:20 < aandrew> for 125mhz? nope
2019-01-23T23:38:33 < aandrew> that's 8ns
2019-01-23T23:38:35 < rajkosto> is it ok if i route nRST through another chip pin
2019-01-23T23:38:35 < Cracki> yeh, that's almost 3 periods
2019-01-23T23:38:50 < aandrew> rajkosto: what do you mean
2019-01-23T23:39:03 < rajkosto> ill also assign it to another gpio just so i can route it out
2019-01-23T23:39:08 < Cracki> alternate function for reset?
2019-01-23T23:39:22 < rajkosto> so there will be 2 pins on stm32 routed to nRST
2019-01-23T23:39:26 < Cracki> oh
2019-01-23T23:39:30 < aandrew> rajkosto: no, it's a dedicated input
2019-01-23T23:39:34 < aandrew> you can route it externally though
2019-01-23T23:39:42 < Cracki> how can two pins be mapped to nrst at the same time?
2019-01-23T23:39:45 < aandrew> i.e. have a GPIO pin on the STM32 drive a n-fet which pulls RST down
2019-01-23T23:39:49 < aandrew> but it'll look glitchy
2019-01-23T23:39:59 < aandrew> you really want to either drive a RST pin on a supervisory IC or use a monostable
2019-01-23T23:40:03 < rajkosto> i have to route it through another unused gpio pin to escape
2019-01-23T23:40:12 < rajkosto> i dont plan on ever setting that gpio
2019-01-23T23:40:13 < aandrew> rajkosto: fix your routing
2019-01-23T23:40:14 < Cracki> routing on pcb you mean?
2019-01-23T23:40:26 < rajkosto> aandrew, not possible to do better
2019-01-23T23:40:29 < Cracki> is there enough space to route between legs?

2019-01-23T23:40:33 < rajkosto> of course not.
2019-01-23T23:40:36 < aandrew> you can set the pin to ADC input and disable the digital buffer but you're just asking for trouble
2019-01-23T23:40:36 < Cracki> or drop to other layer?
2019-01-23T23:40:44 < aandrew> rajkosto: I'm sure it is
2019-01-23T23:40:46 < aandrew> show us the layout
2019-01-23T23:40:49 < cnt> Where’s my fav blxtr
2019-01-23T23:40:50 < Cracki> so that pin will just be unused? sure, why not
2019-01-23T23:41:01 < aandrew> Cracki: because you can't guarantee you'll ever be sure to reset
2019-01-23T23:41:19 < aandrew> if the pin is just a gpio input with pullup enabled (default on blank part) you should be ok
2019-01-23T23:41:27 < aandrew> but what if your errant program ends up driving that pin?
2019-01-23T23:41:29 < Cracki> hmm cut the pin that's "in the way" physically so it doesn't even touch the board
2019-01-23T23:41:33 < rajkosto> i can always break off the tqfp pin
2019-01-23T23:41:35 < rajkosto> before soldering
2019-01-23T23:41:37 < aandrew> drive low = insta-reset which isn't (really) bad but what if it drives it high?
2019-01-23T23:41:40 < rajkosto> but thats not cool
2019-01-23T23:41:47 < aandrew> like I said, fix your layout
2019-01-23T23:41:54 < rajkosto> im just asking, stm32 shouldnt ever glitch anything on PORTB low ?
2019-01-23T23:41:56 < aandrew> I do not believe that it's impossible to escape, especially on tqfp
2019-01-23T23:41:59 < rajkosto> if i dont explicitly tell it to
2019-01-23T23:42:04 < aandrew> it may be UGLY but it should be doable
2019-01-23T23:42:14 < bitmask> heated hoodie is a success, now to slim it down and make it comfortable
2019-01-23T23:42:31 < aandrew> rajkosto: so you're going to guarantee that it's impossible to inadvertendly have that pin become an output?
2019-01-23T23:42:40 < aandrew> bitmask: that's cool
2019-01-23T23:42:41 < aandrew> well warm
2019-01-23T23:42:46 < bitmask> :)
2019-01-23T23:42:57 < Cracki> wow 27h idle
2019-01-23T23:42:57 < aandrew> you put that in some slim girlie hoodie and I will buy one from you for my wife
2019-01-23T23:43:13 < aandrew> she only likes full zippered though (not pullover type)
2019-01-23T23:43:32 < Cracki> CE logo on it :3
2019-01-23T23:44:42 < aandrew> damn, the fastest fet driver I can find on digikey in the same footprint (not sure on pinning) is 5ns
2019-01-23T23:44:55 < bitmask> I ordered some 1mm silicone sheeting to try and make slimmer panels by sandwiching the heater between that instead of in this huge 5-6mm mold.  If that is still too thick then I'll just sew it into fabric and deal with hotspots
2019-01-23T23:45:02 < aandrew> ISL6700
2019-01-23T23:45:27 < aandrew> incompatible pinning
2019-01-23T23:46:29 < aandrew> oh there I have some options if I go to 8ns
2019-01-23T23:48:15 < bitmask> is there any flexible heat shrink tubing? I want to strengthen my wires by using some cover to hold multiple wires together but heat shrink is too stiff, I'm using this wire loom stuff for other parts but something like a more flexible heatshrink would be better
2019-01-23T23:48:33 < bitmask> vs buying multicore wire
2019-01-23T23:48:49 < aandrew> UCC2752x is pin compatible and 6-7ns typical
2019-01-23T23:49:17 < aandrew> 15ns minimum guaranteed input pulse width though

2019-01-24T00:03:15 < jadew> yeah, so I can work on it

2019-01-24T00:04:02 < jadew> or any other material that doesn't melt @ soldering temperatures?
2019-01-24T00:04:35 < Rickta59> so i guess my answer to the question I asked you Cracki was an stm32 board
2019-01-24T00:04:37 < jadew> I need a mill, that's what I need
2019-01-24T00:04:58 < zyp> just grab some bare scrap pcbs and align them around it and tape them down
2019-01-24T00:04:58 < Cracki> bitmask, not heatshrink but there's webbing, and there are helically cut apart plastic tubes you can wrap around
2019-01-24T00:05:14 < jadew> zyp, that's a great idea
2019-01-24T00:05:15 < zyp> so that you get a square slot in the middle that it fits in

2019-01-24T00:34:00 < Rickta59> did anyone see the jeeh code?
2019-01-24T00:34:27 < Rickta59> https://github.com/jeelabs/jeeh/
2019-01-24T00:37:27 < aandrew> nice I found some drivers that will work
2019-01-24T00:38:14 < aandrew> Infineon 2EDN7524 has compatible pinout and minimum pulse of 6-10ns (6 typical)
2019-01-24T01:00:08 < aandrew> englishman: you know that little metal "tape" that they use to stick two pieces of reel strips together? it's got the same hole pattern as the strip itself and allows you to attach a leader to an existing reel?
2019-01-24T01:07:55 < karlp> Rickta59: fuck me, he's off the deepend now.
2019-01-24T01:08:24 < Rickta59> you think? he does seem to go to extremes
2019-01-24T01:08:40 < Rickta59> last i noticed he was deep into forth
2019-01-24T01:08:59 < karlp> I admire his prolific...ness? prolificity? over the years, but somettimes I think he digs massive piles before he decides it might be a bit weird and too far off in one direction
2019-01-24T01:09:09 < Rickta59> now he eschews all defines
2019-01-24T01:10:27 < karlp> nothing wrong with thatt, consts are good too.
2019-01-24T01:10:30 < karlp> fuck the preprocessor
2019-01-24T01:10:39 < Rickta59> he was radio silent for a yaer and this is what he popped up with
2019-01-24T01:10:41 < karlp> and he's using c++. lots of "nice" ways of doing it.
2019-01-24T01:11:57 < Rickta59> i kind of like it... if he used defines it would be perfect
2019-01-24T01:12:13 < karlp> so... why would you need defines then?
2019-01-24T01:12:17 < karlp> yo ulike it already?
2019-01-24T01:12:21 < karlp> I'm missing something
2019-01-24T01:12:33 < Rickta59> defines for the peripheral addresses
2019-01-24T01:12:46 < Rickta59> instead of hard coding them
2019-01-24T01:13:12 < Rickta59> include the stm32fx device include
2019-01-24T01:14:15 < Rickta59> i guess i like the fact that someone is making a thin layer that isn't tarduino or HAL or LL
2019-01-24T01:15:39 < karlp> what?
2019-01-24T01:15:47 < karlp> how is a define not hardcoded?
2019-01-24T01:16:02 < karlp> you just include the right file, like he's doing, and like you'd do with definess?
2019-01-24T01:16:17 < karlp> have you tried mbed?
2019-01-24T01:16:24 < Rickta59> bloated 
2019-01-24T01:16:27 < Rickta59> i have
2019-01-24T01:16:41 < Rickta59> and they lay it on top of hal .. or at least they did the last time i loked

2019-01-24T02:36:28 < englishman> actually i called digikey and asked them once
2019-01-24T02:36:32 < englishman> and they gave me like 3 places
2019-01-24T02:36:37 < englishman> cuz they buy the stuff but dont sell it
2019-01-24T02:36:48 < englishman> digikey is super friendly and helpful all the time it's kind of annoying

2019-01-24T02:37:01 < aandrew> "splice" was the magic word
2019-01-24T02:37:03 < englishman> and open for several hours still
2019-01-24T02:37:17 < aandrew> yep I asked them for the details on their identification system and it's actually some standard
2019-01-24T02:37:25 < aandrew> yep I have an order going in to them

2019-01-24T03:33:02 < englishman> whyd you start routing with less than all the parts placed

2019-01-24T03:34:51 < rajkosto> maybe i wont even use the eeprom and rely just on battery, thus it can remain DNP on the back

2019-01-24T03:46:53 < ColdKeyboard> Thorn: Okay
2019-01-24T03:46:57 < aandrew> and yeah when it gets too tight I just drop designators for anything but things I might want to fuck with (resistor straps, buttons/leds, etc.)
2019-01-24T03:47:08 < ColdKeyboard> I just got two boards and want to test some ping-pong to gauge the range on these babies :)
2019-01-24T03:47:31 < aandrew> rajkosto: routing before placing is pretty much a recipe for shit routing and problems like wanting to run RST# through another GPIO
2019-01-24T03:47:40 < rajkosto> aandrew, sorted that
2019-01-24T03:47:45 < rajkosto> and no, i get that the other way around
2019-01-24T03:47:49 < rajkosto> found out i placed everything too tight
2019-01-24T03:48:20 < aandrew> I spent probably 60-75% of my layout time on placement

2019-01-24T03:49:26 < aandrew> it's hard to see for sure but it looks like you're not adopting a north/south for one layer and east-west for another strategy

2019-01-24T03:50:39 < aandrew> how big are those vias?
2019-01-24T03:50:40 < englishman> bump to 4L it'll be better and doesnt cost much more
2019-01-24T03:50:45 < rajkosto> 0.3mm/0.6mm
2019-01-24T03:50:51 < rajkosto> englishman, costs 72$ vs 10$
2019-01-24T03:50:52 < aandrew> not bad
2019-01-24T03:50:52 < rajkosto> "much more"
2019-01-24T03:50:58 < englishman> pff
2019-01-24T03:51:13 < englishman> where are you getting that, shitstudio
2019-01-24T03:51:22 < rajkosto> anywhere.
2019-01-24T03:51:34 < rajkosto> cheapest "prototype" rate is 6/6, 0.3mm holes, 0.15 annular
2019-01-24T03:51:52 < rajkosto> make any of those better and the price goes way higher
2019-01-24T03:51:54 < englishman> if you are prototyping then why does size matter
2019-01-24T03:52:04 < rajkosto> im gonna stick this into a device
2019-01-24T03:52:14 < rajkosto> im not going to sell these.
2019-01-24T03:53:10 < englishman> then why does price matter
2019-01-24T03:53:26 < rajkosto> because i dont want to pay 72$ for something with like 3$ of components on it ?

2019-01-24T04:08:56 < mawk> if I use DMA with the spi peripheral in slave mode that means it'll register everything I receive inside some address, incrementing the pointer each time ?
2019-01-24T04:09:01 < mawk> and trigger an interrupt
2019-01-24T04:09:25 < rajkosto> if that is how you set it up

2019-01-24T10:14:35 < kakimir> but if it works it's okay
2019-01-24T10:15:19 < rajkosto> i have to add tons of polygon pour cutouts to make mine pretty
2019-01-24T10:16:39 < kakimir> oh
2019-01-24T10:17:21 < kakimir> like car manufs hide their design in arbitrary patterns you hide your ugli board in similar pattern?

2019-01-24T10:27:56 < rajkosto> they follow NO laws
2019-01-24T10:28:17 < Ecco> Hi :)
2019-01-24T10:28:22 < kakimir> they are a wild bunch
2019-01-24T10:28:37 < Ecco> Quick question regarding the HSE crystal: how do you pick its value?
2019-01-24T10:28:51 < kakimir> what value?
2019-01-24T10:28:55 < Ecco> The crystal's
2019-01-24T10:28:57 < rajkosto> what stm
2019-01-24T10:29:09 < Ecco> F4 or F7
2019-01-24T10:29:16 < rajkosto> they can yeet up to 24MHz
2019-01-24T10:29:32 < rajkosto> so just pick integer number like that
2019-01-24T10:29:39 < Ecco> What would be the difference between, say, a 4 MHz crystal with a 4 PLLM and a 25 MHz with a 25 PLLM
2019-01-24T10:29:48 < rajkosto> lower ppm is better, and the capacitance should be pretty low, they recommend like 7pf or something
2019-01-24T10:30:18 < Ecco> rajkosto: how would that translate in terms of crystal frequency?
2019-01-24T10:30:31 < rajkosto> frequency is irrelevant since you divide it to 1MHz anyway ?
2019-01-24T10:30:36 -!- sterna [~Adium@h-90-120.A137.corp.bahnhof.se] has joined ##stm32
2019-01-24T10:31:23 < Ecco> So it has like 0 impact at all?
2019-01-24T10:31:27 < jpa-> Ecco: higher frequency crystals may be easier to find in smaller packages
2019-01-24T10:31:34 < rajkosto> different divider to set in code ?
2019-01-24T10:31:37 < Ecco> jpa-: Interesting :)
2019-01-24T10:31:46 < jpa-> lower frequency crystals may use slightly less power if you are running CPU at low freq also
2019-01-24T10:31:48 < Ecco> No, I was talking about the kind of things jpa said :)
2019-01-24T10:31:55 < jpa-> but for actual operation it doesn't matter too much
2019-01-24T10:32:46 < Ecco> allright
2019-01-24T10:32:51 < jpa-> i guess there might be some effect to phase jitter; I think the less you have to multiply by PLL the less the phase jitter grows, but it might be that the inherent noise in the PLL is higher than that effect anyway
2019-01-24T10:32:51 < Ecco> I have an example where it does matter
2019-01-24T10:33:16 < Ecco> Internal USB-DFU bootloader auto-detects the crystal frequency
2019-01-24T10:33:24 < Ecco> by comparing it to its internal HSI
2019-01-24T10:33:36 < qyx> yes, but on some MCUs not all freq are supported
2019-01-24T10:33:40 < Ecco> yes
2019-01-24T10:33:57 < Ecco> Usually it's "whatever that's an integer number of Mhz between 4 and 25"
2019-01-24T10:34:37 < Ecco> But then, the higher the frequency, the smaller the difference (relatively, 25 and 24 MHz are a lot more similar than 4 and 5)
2019-01-24T10:34:47 -!- benishor [~benny@79.116.208.40] has joined ##stm32
2019-01-24T10:34:49 < Ecco> so the DFU bootloader is more prone to bad auto-detection
2019-01-24T10:34:53 < Ecco> (I've had this happen…)
2019-01-24T10:37:50 < jpa-> how do you know that it was what happened?
2019-01-24T10:38:08 < jpa-> seems quite difficult to debug

2019-01-24T10:40:01 < Ecco> It was really hard to debug
2019-01-24T10:40:22 < Ecco> 1/ Swapping MCUs between falty board and working one had the issue following the MCU
2019-01-24T10:40:24 -!- davor_ is now known as davor
2019-01-24T10:40:33 < Ecco> 2/ Device got enumerated but flashing failed quickly
2019-01-24T10:41:06 < Ecco> (so gave an idea about clock drift)
2019-01-24T10:41:22 < Ecco> 3/ Attached a debugger, peeked the PLL registers, found that auto-detection was off by 1 MHz
2019-01-24T10:41:41 < Ecco> 4/ Measured HSI with MCO pin, sure enough, it was off by 4%
2019-01-24T10:41:41 < jpa-> nice
2019-01-24T10:44:33 < Ecco> So as a safety measure, I'm considering using a smaller freq crystal
2019-01-24T10:44:47 < Ecco> Something like 25 MHz down to 16 or 8
2019-01-24T10:44:51 < Ecco> Maybe even 4?
2019-01-24T10:44:57 < Ecco> We're using a 3225 package
2019-01-24T10:45:03 < Ecco> would you guys have any recommendation?
2019-01-24T10:45:46 < jpa-> I've always just used 8MHz everywhere because that seems most common
2019-01-24T10:46:04 < qyx> I am using 3225 16MHz everywhere
2019-01-24T10:48:30 < Haohmaru> i think i also picked the 3225 SMD package
2019-01-24T10:49:44 < zyp> Ecco, what do you mean by safety measure?
2019-01-24T10:49:58 < zyp> oh, for auto detection
2019-01-24T10:50:42 < zyp> I've never worried about that, I'm always doing my own bootloader which knows the actual crystal value
2019-01-24T10:51:26 < Haohmaru> uh, shouldn't the bootloader use some internal clock source?
2019-01-24T10:51:37 < Haohmaru> if it's a generic one i mean
2019-01-24T10:51:40 < zyp> HSI isn't accurate enough for USB
2019-01-24T10:51:48 < Haohmaru> oh
2019-01-24T10:51:51 < Haohmaru> meeeh
2019-01-24T10:52:05 < zyp> except the new parts with HSI48/CRS, you need HSE for USB
2019-01-24T10:52:06 < Haohmaru> then ya gotta recompile teh bootloader i guess
2019-01-24T10:53:12 < zyp> personally I've always just went with 8 MHz out of habit, except one board where I had a 25 MHz crystal for the ethernet phy, so I used the same part for the mcu to save a BOM line
2019-01-24T10:53:13 < Haohmaru> my xmega bootloader (sorry) uses internal clock, doesn't matter if the frequency is quite off even
2019-01-24T10:53:38 < zyp> for usb?
2019-01-24T10:54:03 < Haohmaru> nah, for my devices (no USB there, just ethernetz)
2019-01-24T10:54:12 < zyp> uh
2019-01-24T10:54:26 < zyp> I don't assume you're doing ethernet without a crystal :p
2019-01-24T10:54:42 < Haohmaru> the w5500 deals with the ethernetz
2019-01-24T10:55:02 < Haohmaru> all communications before that are synchronous, so their crystals don't matter too much
2019-01-24T10:57:50 < jpa-> Haohmaru: stm32 bootloader also supports serial, spi etc. with internal oscillator, it's just USB that it needs HSE for
2019-01-24T10:59:27 < Haohmaru> i guess you can "try" to switch to an external crystal, and if it happens that there isn't one - you could detect that and switch to an internal clock?

2019-01-24T11:03:13 < jpa-> Haohmaru: nah, on stm32 you can enable the external oscillator without switching over to it
2019-01-24T11:04:18 < Haohmaru> yes, but i mean.. there's a way to figure out if it's "usable" (what if it's not populated at all) without crashing or freezing the program..
2019-01-24T11:04:23 < Haohmaru> right?
2019-01-24T11:04:57 < qyx> yes, you just enable it a check if it is enabled
2019-01-24T11:05:08 < Haohmaru> right
2019-01-24T11:05:19 < qyx> there is a HSEON and HSERDY or such
2019-01-24T11:05:40 < Haohmaru> but i guess, you maybe can't know it's frequency
2019-01-24T11:05:56 < qyx> there is also a clock recovery system for that purpose
2019-01-24T11:06:01 < qyx> and you can
2019-01-24T11:06:05 < Haohmaru> altho, even if you do, hardcoded stuff won't automagically update itself
2019-01-24T11:06:12 < qyx> because usually you have HSI16 or MSI or whatever
2019-01-24T11:06:23 < qyx> you can measure its freq using another osc
2019-01-24T11:06:30 < Haohmaru> nice
2019-01-24T11:06:40 < qyx> or with LSE

2019-01-24T17:37:17 < Thorn> you have function flip(int k, int[] array) which reverses the first k elements of array, e.g. flip(3, [1,2,3,4,5]) -> [3,2,1,4,5]. write an array sort function using only flip() to mutate the array.
2019-01-24T17:37:59 < Haohmaru> wut is dis? homework?!
2019-01-24T17:38:40 < Thorn> lol no
2019-01-24T17:38:57 < Cracki> bubble sort is based on adjacent-element flips
2019-01-24T17:39:10 < Cracki> and if you aren't allowed to use slices, you're fucked anyway
2019-01-24T17:39:23 < Cracki> quicksort and mergesort are based on "slices" (in general)
2019-01-24T17:39:48 < Cracki> oh, still, this works too...
2019-01-24T17:39:53 < Cracki> it feels like towers of hanoi
2019-01-24T17:40:16 < Haohmaru> this is gonna be an inefficient sort
2019-01-24T17:40:26 < Cracki> you have the flipper, with which you can pick up the "last" element and pull it down into first position
2019-01-24T17:41:53 < Cracki> one iteration: for w = n downto 2: if x[0] > x[w-1] then flip(w, array)
2019-01-24T17:42:24 < Cracki> can't do it upwards because the middle section gets flipped all the time
2019-01-24T17:45:01 < Steffanx> Lol sorry Haohmaru, cat on keyboard talk.
2019-01-24T17:45:53 < Haohmaru> <excuses.txt>
2019-01-24T17:46:07 < Steffanx> A valid one.
2019-01-24T17:46:17 < Cracki> that flip() can be understood to flip x[0] and x[w-1], to hell with anything in between. there you have bubblesort now. just make sure the loop counting direction is ok
2019-01-24T17:46:26 < Thorn> next time the cat will learn how to /ban

2019-01-24T18:52:43 < zyp> one of the things that's convenient about ikea is that I have a warehouse like 40 km away, so it's easy to head over and pick up shit I need whenever
2019-01-24T18:53:29 < zyp> but for some reason, they don't stock the kitchen bases in black
2019-01-24T18:54:50 < zyp> shit they don't stock can be ordered for pickup for free though, so I ordered three tall bases a couple of weeks ago
2019-01-24T18:55:20 < zyp> originally they were supposed to arrive on the 17th, then I got a message saying they were delayed until 25th, then 29th, then 11th of february
2019-01-24T18:56:08 < zyp> apparently that shit is almost not in stock at any warehouses in norway either
2019-01-24T18:56:19 < zyp> turns out in denmark it is
2019-01-24T18:56:50 < zyp> so now I've rented a van for tomorrow, bought ferry tickets, and are going to head over to denmark to pick them up
2019-01-24T18:57:16 < zyp> also turns out that they are cheaper enough in denmark that the rental van and the ferry tickets pays for itself by doing that
2019-01-24T18:59:32 < Cracki> lol
2019-01-24T18:59:43 < Cracki> did you call ahead to reserve what you want?

2019-01-24T19:39:41 < zyp> some of the parts I need are cheaper in norway, so I'll naturally not buy them in .dk
2019-01-24T19:39:49 < Cracki> so... 240 saved on the wares, and free to spend on transportation
2019-01-24T19:39:56 < zyp> yeah
2019-01-24T19:40:24 < zyp> I think I paid around 140 for the van and ferry tickets
2019-01-24T19:40:30 < Cracki> I wonder how they arrive at these price differences
2019-01-24T19:40:46 < zyp> and I'd needed to rent a van to pick up the stuff either way
2019-01-24T19:40:53 < Cracki> it's not like materials and production costs any more or less
2019-01-24T19:40:58 < zyp> true
2019-01-24T19:41:05 < zyp> just varying margins, I assume
2019-01-24T19:41:43 < bitmask> silicone sheet comes tomorrow, hopefully its thin enough to make a comfortable heating panel
2019-01-24T19:42:30 < zyp> one of the products almost seems to be wrongly priced in norway, it's 27€ in .dk and 87€ in .no
2019-01-24T19:44:41 < Cracki> maybe they switched particle board for card board
2019-01-24T19:44:58 < Cracki> or... new models, and old are on sale ¯\_(ツ)_/¯
2019-01-24T19:45:14 < zyp> no, exactly same product

2019-01-24T19:47:04 < englishman> no sense driving an empty van
2019-01-24T19:48:51 < emeb> So here's a funny story: trying to build a little F042 project to do USB->SPI (to stand in for an FT2232 in an FPGA application)
2019-01-24T19:49:16 < emeb> built up my own little C project for that using HAL + USB Device stuff supplied by ST
2019-01-24T19:49:33 < zyp> englishman, haha, didn't even think about that
2019-01-24T19:49:39 < emeb> Got it all compiling last night and when hooked to a host the descriptor is all mangled.
2019-01-24T19:49:56 < zyp> englishman, by the way, I hear we have a bigger moose than you
2019-01-24T19:50:11 < englishman> I've also been hearing about that nonstop
2019-01-24T19:50:16 < emeb> after much banging on it discovered that it was the GCC optimization level of -O3 that was causing problem.
2019-01-24T19:50:24 < englishman> yours is also the t1000 model apparently
2019-01-24T19:50:57 < emeb> -O0 thru -O2 works fine though so *shrug*
2019-01-24T19:51:52 < zyp> emeb, then it's one out of two
2019-01-24T19:52:01 < zyp> either there's a bug in one of the optimizer steps
2019-01-24T19:52:03 < englishman> does it work in keil -03
2019-01-24T19:52:37 < emeb> don't have keil
2019-01-24T19:52:38 < zyp> or you're making assumptions about some undefined behavior that one of the optimizer steps throws out
2019-01-24T19:52:53 < emeb> zyp: this is all ST codes. None of mine
2019-01-24T19:53:01 < zyp> optimization dependant bugs are usually the latter
2019-01-24T19:53:02 < emeb> (all auto generated from CubeMX)
2019-01-24T19:53:06 < zyp> well
2019-01-24T19:53:12 < zyp> that doesn't mean it's bug-free :)
2019-01-24T19:53:25 < emeb> So I assume ST has some undefined expectations in their stuff.

2019-01-24T23:07:41 < Cracki> Rajko, must have something to do with parasitic properties. a while ago I saw some info on stuff like this, where they have >2pin footprints for L and C too

2019-01-24T23:10:44 < Cracki> so... 2p is just crystal and needs circuitry around it, 4p might generate a nice square wave all on its own

2019-01-24T23:12:41 < zyp> Cracki, what are you talking about? are you mixing up crystals and crystal oscillators?
2019-01-24T23:13:06 < Cracki> _he_ is talking about something, what it is or could be is the question
2019-01-24T23:13:46 < zyp> plain crystals come in both 2 and 4-pin packages, the latter seems more common
2019-01-24T23:14:07 < Cracki> so my first comment is probably wrong, but I wouldn't be surprised by crystals with 4p
2019-01-24T23:14:14 < zyp> the 4-pin ones have two unused pins that you normally either ground or leave floting
2019-01-24T23:14:44 < Cracki> what's the point
2019-01-24T23:14:47 < zyp> and then you have crystal oscillators, which come in similar packages to the 4-pin crystals, and as you say do output a square wave on their own
2019-01-24T23:15:02 < zyp> point of the 4-pin ones? probably mechanical stability
2019-01-24T23:15:32 < zyp> one pad in each corner attaches better than just one on each end
2019-01-24T23:17:06 < Rajko> Cracki, those are explicitly called oscillators
2019-01-24T23:17:16 < Rajko> and are way larger/more expensive
2019-01-24T23:17:28 < Cracki> then it's simple
2019-01-24T23:18:13 < Rajko> its still that some 3225-4P have metal case (and its connected to the 2 other pins) but some have black case and the 2 other pins are unconnected

2019-01-24T23:43:02 < jadew> I'll look for a video
2019-01-24T23:43:06 < jadew> maybe it can do what I want
2019-01-24T23:43:25 < qyx> cad like drawing?

2019-01-24T23:44:08 < jadew> qyx, yeah, I'm using inkscape, but I don't know how to to tell it that I want an arrow to be exactly the same distance from the edge as the arrow on the other side
2019-01-24T23:44:29 < qyx> did you try "align" toolbar?

2019-01-24T23:47:00 < jadew> eventually, I'd like the ability to enter that distance manually
2019-01-24T23:47:31 < jadew> BrainDamage, yep, youtube says it's not
2019-01-24T23:47:33 < jadew> it looks nice
2019-01-24T23:47:34 < jadew> thanks
2019-01-24T23:47:56 < qyx> I'll just do some group&center
2019-01-24T23:48:12 < qyx> but I don't know how to apply that to page borders actually
2019-01-24T23:48:19 < jadew> qyx, that would work too, thanks for the tip
2019-01-24T23:49:08 < jadew> it worked
2019-01-24T23:49:35 < jadew> but now I want text to be the same distance from the objects :P

2019-01-24T23:51:16 < jadew> BrainDamage, I take it you know about it because of the LaTeX capability?
2019-01-24T23:51:25 < BrainDamage> yup

2019-01-25T05:42:39 < ds2> mouser has a slightly different selection...very useful
2019-01-25T05:42:51 < ds2> like parts of Oki/Metcal irons
2019-01-25T05:43:08 < rajkosto> probably shouldnt trust the dimensions on this weird model, huh ? https://grabcad.com/library/oled-tft-0-96-inch-64x128-monochrome-i2c-1

2019-01-25T05:44:30 < englishman> wtf
2019-01-25T05:44:48 < englishman> who the shit is going to buy that on mouser

2019-01-25T05:47:28 < rajkosto> i need the "folded flex cable" dimensions to know exactly where to place the pads so it doesnt stick up or fall short
2019-01-25T05:51:33 < aandrew> short of buying one I wouldn't trust a random drawing
2019-01-25T05:51:37 < rajkosto> i have one

2019-01-25T05:52:36 < rajkosto> probably best to just copy their pcb
2019-01-25T05:52:40 < rajkosto> incl slot

2019-01-25T07:26:29 < Cracki> ok so I managed to trim the PCB off that solidworks file... but now it's inventor and I don't know if that helps you at all
2019-01-25T07:27:34 < rajkosto> yes some tools let you import step and solidworks but not as a "part" but as a generic 3d model
2019-01-25T07:27:41 < rajkosto> which then cant be used as step/solidworks

2019-01-25T10:13:55 < kakimir> the thing with board was that copper needed to reach as close as possible to pcb edge because of electrical contact in the edge

2019-01-25T10:14:55 < kakimir> I think after talking a while about it with customer service I got it down to 0.1mm or so

2019-01-25T10:27:35 < kakimir> iirc. some low output voltage variations need minimum load to be stabile or so
2019-01-25T10:28:05 < kakimir> example circuits using load resistor to archive minimum current

2019-01-25T10:29:45 < Haohmaru> the negative rail is -17VDC and the max consumption is like less than 100mA

2019-01-25T10:36:13 < ds2> check with a scope to see if there is any oscillation
2019-01-25T10:36:19 < Haohmaru> i've put a trimpot with the mc33063 so i can adjust the actual voltage a bit
2019-01-25T10:36:21 < kakimir> I follow that rule always
2019-01-25T10:36:30 < ds2> some switchers can't reduce the duty cycle sufficiently for low output
2019-01-25T10:36:51 < Haohmaru> don't have a scope at home :/
2019-01-25T10:38:24 < ds2> what are you starting with ?
2019-01-25T10:38:27 < ds2> +17V?
2019-01-25T10:39:32 < Haohmaru> +21VDC (it comes from a transformer > fullwave rectifier > reservoir caps)
2019-01-25T10:39:53 < kakimir> what is maximum operating voltage of that regu?
2019-01-25T10:39:55 < ds2> why not get -17V from the transformer?
2019-01-25T10:40:13 < Haohmaru> mm
2019-01-25T10:40:27 < ds2> or you out of space for caps? :D
2019-01-25T10:40:28 < Haohmaru> not sure how
2019-01-25T10:40:50 < qyx> so -21V -> -17V -> -15V
2019-01-25T10:41:03 < qyx> why is there a smps even
2019-01-25T10:41:05 < ds2> what kind of full wave rectifier? bridge? also what kind of xformer?
2019-01-25T10:41:32 < ds2> if you have a center tap, then it is easy
2019-01-25T10:41:34 < Haohmaru> the device actually needs +15 and -15 to work, it has LM7815 and LM7915 (iirc) and also 5V, so i need to feed enough voltage so those work
2019-01-25T10:41:58 < ds2> otherwise, you could have 2 diodes - one for + and one for -...make the other end of the xformer gnd
2019-01-25T10:42:10 < ds2> just sucks for power factor stuff and cap sizing
2019-01-25T10:42:16 < Haohmaru> thus i feed the unregulated 21V directly to the 7815, while i use a mc33063 to generate -17V for the 7915, which should be enough
2019-01-25T10:42:26 < ds2> if you have a center tap, then a bridge can give you +/- if you use the CT as reference
2019-01-25T10:42:57 < Haohmaru> rectifier is 4 diodes
2019-01-25T10:43:10 < Haohmaru> transformer is not center tap
2019-01-25T10:43:14 < ds2> bridge I assume
2019-01-25T10:43:36 < Haohmaru> i get 26VDC with absolutely no load, it falls to 21VDC when the device is running
2019-01-25T10:43:58 < Haohmaru> the positive power rail is more loaded because the device makes its 5V from it
2019-01-25T10:46:31 < Haohmaru> oh and yes.. there is a nifty online calculator for this regulator
2019-01-25T10:47:51 < Haohmaru> i'll check what's going on with the actual -15VDC while the problem is present, and i'm gonna try putting a resistor to load it a bit more
2019-01-25T10:48:21 < Haohmaru> i do have LEDs on each power rail, but they are drawing less than 1mA

2019-01-25T15:09:18 < Ecco> (I know this one's an IDe connector specifically, but what's the general name?)
2019-01-25T15:09:27 < karlp> elecrow takes nice pictures of your pcbs when they are ready to go
2019-01-25T15:09:38 < Haohmaru> that's a flat cable
2019-01-25T15:09:40 < karlp> Ecco: IDC cable (insulation displacement)
2019-01-25T15:09:42 < Haohmaru> IDC
2019-01-25T15:11:14 < Ecco> thanks!
2019-01-25T15:11:26 < Ecco> does that always mean a 2.54mm pitch?
2019-01-25T15:11:33 < Haohmaru> no
2019-01-25T15:11:48 < Ecco> ok :)
2019-01-25T15:12:02 < Haohmaru> but 2.54 and 1.27mm pitch are two very common ones
2019-01-25T15:12:29 < Ecco> Looks like the RPi header is *exactly* an IDE one
2019-01-25T15:12:36 < Ecco> Have you guys ever tried?
2019-01-25T15:13:01 < Haohmaru> well IDE cables fit on your usual header pins
2019-01-25T15:13:19 < Haohmaru> ehm i meant IDC cables
2019-01-25T15:13:46 < Haohmaru> also, the actual connector is easy to put onto the cable with almost bare hands

2019-01-25T15:53:17 < Thorn> jlcpcb canceled chinese new year? https://support.jlcpcb.com/article/73-jlcpcb-spring-festival-holiday-schedule
2019-01-25T15:57:59 < kakimir> Standard Prototype PCB Orders(HASL, Green Solder Mask) will be proceeded with production. Multi-layer PCB orders, Stencil, small-batch orders won't be put into production until Feb 12th.
2019-01-25T15:58:20 < kakimir> multilayer, small-batch etc.
2019-01-25T15:58:38 < karlp> Ecco: original rpi header was designed to fit 40pin ide cables yes, but aren't the new ones longer?
2019-01-25T15:58:49 < Haohmaru> do i see Comic Sans in that table?!
2019-01-25T15:58:55 < Thorn> but they initially decided to start holidays on the 27th
2019-01-25T15:59:21 < Ecco> karlp: I don't think they changed. Did they?
2019-01-25T16:00:48 < rajkosto> Haohmaru, actually just uploading the AOI images of your board to the website as its finished should be perfect, for seeing defects before you get the boards, if slow shipping
2019-01-25T16:01:15 < Ecco> Which hole size / pad size would you use for 2.54mm-pitched headers?
2019-01-25T16:01:25 < Ecco> I picked 1mm hole, 1.5mm pad diam
2019-01-25T16:01:44 < Haohmaru> rajkosto that would be useful indeed
2019-01-25T16:01:55 < rajkosto> Ecco, i use 1 mm hole 1.75 mm pad
2019-01-25T16:02:21 < Haohmaru> Ecco don't you have some sort of library with these very common components?
2019-01-25T16:02:29 < Ecco> Haohmaru: well, no
2019-01-25T16:02:34 < Haohmaru> how come?!
2019-01-25T16:02:40 < Haohmaru> wut EDA you're using
2019-01-25T16:02:44 < Ecco> Altium
2019-01-25T16:02:58 < rajkosto> use the wizard ?
2019-01-25T16:02:59 < Haohmaru> i thought you might be MSPaint'ing gerbers
2019-01-25T16:03:15 < Haohmaru> doesn't that thing have libraries, dafuq
2019-01-25T16:03:30 < karlp> heh, intel killed edison, now they're killing quark :)
2019-01-25T16:03:39 < rajkosto> Haohmaru, it doesnt really come wiht anything useful no
2019-01-25T16:03:49 < rajkosto> there are a few community libraries but just make your own footprints
2019-01-25T16:03:51 < rajkosto> for the basic stuff
2019-01-25T16:03:57 < rajkosto> usually using the wizard
2019-01-25T16:04:03 < Haohmaru> huh
2019-01-25T16:04:13 < rajkosto> for proper chips you'd be using the "Altium Vault"
2019-01-25T16:04:25 < PeterM> for pretty much any 0.1" header i ahve seen the mfgs suggest 0.8mm holes
2019-01-25T16:04:34 < Haohmaru> well then, you should check the datasheet of yer header pins and they should typically have a suggested footprint
2019-01-25T16:04:43 < rajkosto> arent the pins 0.8mm square
2019-01-25T16:04:48 < rajkosto> so 1.0mm round needed
2019-01-25T16:04:56 < rajkosto> for tolerance wankery
2019-01-25T16:05:52 < Haohmaru> i measure more like 0.7-ish
2019-01-25T16:06:08 < Haohmaru> iirc in kicad the drills are like 1.016mm or some such
2019-01-25T16:06:15 < rajkosto> wurth footprint has 1.1mm holes iirc
2019-01-25T16:06:43 < karlp> Ecco: yeah, otherway round, first rpis had 26 pin headers, new ones were designed for ide, with 40 pin
2019-01-25T16:07:06 < rajkosto> do they have GND in the same 6 places as the IDE cable does too ?
2019-01-25T16:07:11 < PeterM> sorry, yep 1.016mm is correct,  0.8 is for 0.05inch stuff
2019-01-25T16:08:31 < Haohmaru> one datasheet says 0.64mm
2019-01-25T16:08:56 < Haohmaru> or 0.025"
2019-01-25T16:09:53 < rajkosto> Ecco, https://www.we-online.com/web/en/electronic_components/produkte_pb/bauteilebibliotheken/altium/altium.php Altium_WR-PHD_PIN_HEADER (rev18b).IntLib (Rev. 18b)
2019-01-25T16:10:20 < rajkosto> totally unnecessary and likely has the pins numbered wrong
2019-01-25T16:10:24 < rajkosto> just make your own
2019-01-25T16:11:04 < Haohmaru> wowz, i feel lucky i went with kicad
2019-01-25T16:11:16 < rajkosto> the wurth footprint uses 1.1mm hole 1.6mm pad
2019-01-25T16:11:28 < rajkosto> Haohmaru, it has a wizard for easily generating these as you need them
2019-01-25T16:11:37 < Haohmaru> sure but..
2019-01-25T16:11:46 < rajkosto> generate exactly pin count you need
2019-01-25T16:12:00 < rajkosto> or use these weird EU manuf provided ones
2019-01-25T16:12:10 < Haohmaru> i don't like reading datasheets even for the most bloody common passive components
2019-01-25T16:12:45 < Haohmaru> it'd suck if i get everything right except the pitch of a stupid header
2019-01-25T16:12:54 < PeterM> Haohmaru i am going to guess you probably dont respect votlage ratings on smd resistors either
2019-01-25T16:12:55 < Haohmaru> or the drill diameter
2019-01-25T16:12:59 < rajkosto> no guarantee that is right with the crappy eagle makershit libs either

2019-01-25T16:13:27 < Haohmaru> PeterM define "respect"
2019-01-25T16:14:11 < qyx> like using 0603 resistors for 230V
2019-01-25T16:14:30 < PeterM> "its ok because its 1meg ohm, thats like no current, its fine"
2019-01-25T16:14:32 < rajkosto> 1206 1uF capacitors that are "high voltage 100V" are expensive
2019-01-25T16:15:06 < Haohmaru> well, i wouldn't put 0603 there, it's too tiny and a smol lightning bolt could just jump over its legs
2019-01-25T16:15:38 < Haohmaru> i'd probably put a THT resistor
2019-01-25T16:16:18 < Haohmaru> but i've not done any such circuits (it smells like one of those inductorless psu designs)
2019-01-25T16:17:10 < qyx> even in unductorful you will usually need some to bootstrap-power the switcher
2019-01-25T16:17:40 < Haohmaru> i am kinda scared of electricity, so i naturally am worried about any exposed metal that might have lots of voltage on it
2019-01-25T16:17:50 < rajkosto> how much is lots
2019-01-25T16:17:55 < karlp> stupid microchip ref design uses _seven_ series resistors for the mains incomers :)
2019-01-25T16:18:03 < karlp> AD only uses 2 :)
2019-01-25T16:18:12 < PeterM> standard 1/4 watt th resistors arent good for mains either...
2019-01-25T16:18:48 < Haohmaru> i don't know PeterM, i've only read some microsh*t document about inductorless psu crap, out of curiousity
2019-01-25T16:19:12 < Haohmaru> i have eggzactly one board so far with 230VAC on it, and it goes to a transformer
2019-01-25T16:20:47 < karlp> (didyou read the datasheet for the transformer? ;)
2019-01-25T16:21:00 < Haohmaru> yes?
2019-01-25T16:21:45 < rajkosto> do you have the fuse, ceramic cap, and ntc before the transformer ?
2019-01-25T16:22:08 < Haohmaru> no NTC
2019-01-25T16:22:16 < PeterM> usually 1/4w tht resistors are rated to maximum working voltage of 350v, mains with a peak >350v is still within spec for lots of countries
2019-01-25T16:23:20 < Haohmaru> i was thinking about NTC but couldn't decide what, so i went "meh"
2019-01-25T16:23:28 < PeterM> just sayin, its worth while reading spec sheets on passives too, or atleast knowing them.
2019-01-25T16:23:40 < Haohmaru> certainly
2019-01-25T16:24:30 < Haohmaru> but some components are so common and sorta no-brainer level that it's dumb if you have to draw your own footprints
2019-01-25T16:25:01 < Haohmaru> some datasheets even don't show a suggested footprint, they just tell you what kind of package or footprint it is and that's all
2019-01-25T16:25:31 < PeterM> and then you go to the mfg website, go to their package spec page and downlaod the pdf for that package

2019-01-25T16:27:03 < PeterM> ^
2019-01-25T16:27:10 < PeterM> plus, you only need to make the footprint once
2019-01-25T16:27:10 < Haohmaru> why tho?
2019-01-25T16:27:22 < Haohmaru> it's right there in the list
2019-01-25T16:27:28 < PeterM> because you will always need to make footprints
2019-01-25T16:27:40 < PeterM> what if it isnt "right there on the list"?
2019-01-25T16:27:42 < Haohmaru> i've been making footprints since the beginning
2019-01-25T16:27:55 < Haohmaru> just not for the common/boring parts since the library has them
2019-01-25T16:28:14 < rajkosto> well altium comes with "FPGA 32-bit components" whatever that is
2019-01-25T16:28:43 < rajkosto> youre supposed to get the rest from the internet, the vault, or build up your own library as you go
2019-01-25T16:29:15 < rajkosto> https://images.sshnuke.net/2019-01-25_15-29-13_FU4ilQp35.png comes with these
2019-01-25T16:29:17 < PeterM> if you want to use someone else footprint library like you are doing with kicad, you can do that with altium too
2019-01-25T16:29:21 < Haohmaru> i got my own library of symbols and footprints since the beginning, but it only has some exotic or obscure stuff
2019-01-25T16:29:50 < Haohmaru> ah, then why is mr Ecco not using it?

2019-01-25T16:31:16 < Haohmaru> when i'm making a symbol or footprint, i'm always worried that i might make a mistake and f*ck it up, so i do it very carefully and tripple-check stuff
2019-01-25T16:31:53 < Haohmaru> so far i think i only f*cked up the distance between the NPTH holes on a DSUB-25 port
2019-01-25T16:32:17 < Haohmaru> but i could still plug it in by bending the metal mounting legs
2019-01-25T16:32:29 < PeterM> Haohmaru a good sanity check is adding the 3d models that the manufacturer provides
2019-01-25T16:32:36 < Haohmaru> thus i prefer to use the library ones because so far they worked perfectly
2019-01-25T16:32:44 < rajkosto> anyway whole argument is moot since it comes with 2.54" and 1.27" header symbols/footprints
2019-01-25T16:32:44 < PeterM> you should do that anyway so you can check component clearances too
2019-01-25T16:33:17 < rajkosto> its just that nobody who uses altium uses them, forgot they were
2019-01-25T16:33:20 < Haohmaru> haven't had issues so far besides the dsub25

2019-01-25T16:34:35 < rajkosto> the realtime 3d view in altium is supremely handy in checking clearances when component placing, or seeing if you got the footprint right/it properly accomodates the component
2019-01-25T16:34:58 < Haohmaru> i *do* check them a little bit, for example, on some THT diode, i'd check like if the drill hole is big enough for the leg of the thing, but these are quick checks
2019-01-25T16:36:24 < Haohmaru> most components i've used don't have exotic clearance requirements, so the illustration/outline on their Fab layer and the actual Courtyard is simple enough
2019-01-25T16:36:44 < rajkosto> still helps so much to see it all in 3d ocassionally
2019-01-25T16:37:02 < rajkosto> with only 2d and all the layers visible unstacked, you lose sense of scale
2019-01-25T16:37:05 < Haohmaru> i also check the 3D view very often and stare around to see anything fishy
2019-01-25T16:37:30 < Haohmaru> i switch to high-contrast mode and/or hide certain layers
2019-01-25T16:38:00 < Haohmaru> otherwise yeah, the pcb layout editor tends to look like a rainbow vomit
2019-01-25T16:44:54 < Haohmaru> or like chewed-up M&Ms
2019-01-25T17:00:59 < c10ud> dongs, how do you deal with the constant stream of bugs of altium?
2019-01-25T17:01:31 < Haohmaru> he vomits vulgar words?

2019-01-25T17:09:42 < zyp> disadvantage with going to denmark for ikea is that now I've got hours to waste before return ferry leaves

2019-01-25T17:10:03 < c10ud> Haohmaru, idk I'll wait and see if he manages to unfuck it
2019-01-25T17:10:11 < Haohmaru> Ecco the diameter usually is the key
2019-01-25T17:10:30 < Ecco> I assume 5mm?
2019-01-25T17:10:58 < Haohmaru> well there are 3mm ones, 5mm, 8mm, 10mm probably others, and then there are non-round ones too
2019-01-25T17:11:05 < Ecco> Sure :)
2019-01-25T17:11:09 < jpa-> zyp: is it so much cheaper in denmark?
2019-01-25T17:11:31 < zyp> 2400 NOK price difference on the stuff I'm buying
2019-01-25T17:12:04 < zyp> but the main reason is that half the stuff I wanted is not stocked at my local ikea
2019-01-25T17:12:29 < zyp> I originally backordered it on the 7th, delivery on the 17th
2019-01-25T17:12:52 < zyp> then shit got delayed, new estimates was 25th, 29th and then finally feb 11
2019-01-25T17:14:47 < zyp> 2735 DKK here, 5695 NOK for the same products in norway
2019-01-25T17:15:25 < PeterM> Haohmaru i find the models extremely useful if you use things like right angle mounted through hole capacitors, if you go by the bounding box, they're huge, but if you have them as a cylinder, you get about 60-70% of the area underneath them because they have clearence except in the center
2019-01-25T17:15:26 < zyp> 5965*
2019-01-25T17:15:55 < zyp> i.e. like 40% off
2019-01-25T17:16:50 < Haohmaru> sure

2019-01-25T18:35:57 < emeb> what's a good way to do a hardware-based delay within an ISR on an F0 part?
2019-01-25T18:36:31 < emeb> can't use HAL_Delay() because that relies on Systick ISR which will be held off inside an ISR
2019-01-25T18:37:21 < emeb> On F3/F4/F7 parts I'd use zyp's cyclesleep stuff which runs off the cycle counter, but F0 parts don't have that feature
2019-01-25T18:39:12 < Thorn> emeb: probably start a timer in one shot mode and busy wait for it to stop
2019-01-25T18:39:18 < aandrew> why on earth are you delaying in an ISR
2019-01-25T18:39:26 < aandrew> rethink your implementation
2019-01-25T18:40:18 < emeb> Thorn: yeah, could do that.
2019-01-25T18:40:25 < emeb> aandrew: fair point. 
2019-01-25T18:41:26 < emeb> aandrew: this is bitbanging on some external hardware that can't respond instantly. putting the hardware interaction outside the ISR gets really ugly.
2019-01-25T18:41:36 < aandrew> right, I know that for ever "rule" there are exceptions
2019-01-25T18:41:58 < aandrew> but delays in ISRs are pretty bad because you're blocking evyrhting else (forget nested interupts for the moment)
2019-01-25T18:42:08 < aandrew> how long are you delaying?
2019-01-25T18:42:31 < emeb> aandrew: probably not more than a few tens of microseconds.
2019-01-25T18:43:15 < aandrew> you could use the ISR to drive a state machine and then spin in the main loop
2019-01-25T18:43:16 < aandrew> but yeah
2019-01-25T18:43:49 < aandrew> that way you could set up the timer in the pin change ISR and bump the state, timer expriation ISR bumps the state etc
2019-01-25T18:43:56 < aandrew> and main loop is doing the actual bit moves
2019-01-25T18:44:04 < aandrew> not as straightforward
2019-01-25T18:44:06 < aandrew> and maybe overdesign
2019-01-25T18:44:33 < aandrew> all you can do in F0 is develop a nop loop for say a microsecond or tens of microseconds
2019-01-25T18:45:18 < emeb> the trouble is that this ISR is the USB CDC receive. I can't bail out of it until I use the data it gives me, and I can't use the data until I bang the hardware and hand off the data.
2019-01-25T18:45:32 < emeb> ie - exiting fast is not the ideal.
2019-01-25T18:45:50 < jpa-> why can't you bail out of it? some weird stack that has to get the buffer back instantly?
2019-01-25T18:46:01 < jpa-> normally the host will happily wait for the device
2019-01-25T18:46:05 < aandrew> the "correct" way to do it would be to stall until you have data and then the next request works
2019-01-25T18:47:32 < emeb> OK - definitely no expert on how USB tx/rx works, but AIUI the receive ISR is called when there's data in the buffer from the OUT endpoint. I need to use that data before proceeding, otherwise it's overwritten by the next rx.

2019-01-25T18:48:24 < emeb> so stalling in that ISR is how the system handshakes with the host.
2019-01-25T18:48:34 < jpa-> emeb: what usb stack is this?
2019-01-25T18:48:39 < aandrew> looks like you need to default to stall and then only when data comes in from hw, allow the next request to return data
2019-01-25T18:48:47 < emeb> jpa-:  evil ST USBD stack
2019-01-25T18:52:00 < emeb> (the one that CubeMX spits out when you select USB middleware on F0)

2019-01-26T02:11:40 < Cracki> gave up
2019-01-26T02:11:52 < Cracki> I did separate it, but there's nothing of value there
2019-01-26T02:12:01 < Cracki> you can just construct all that from the drawing

2019-01-26T02:25:20 < rajkosto> the through hole footprints dont have M1 and M2 pads
2019-01-26T02:27:08 < englishman> pad is not a port
2019-01-26T02:27:36 < rajkosto> i  have M1 and M2 on the schematic symbol so i can tie them to gnd or shield or leave them floating as i desire
2019-01-26T02:27:52 < rajkosto> but this only applies to the smd footprint, the th footprint doesnt have those
2019-01-26T02:27:57 < rajkosto> so it cant compile the integrated library
2019-01-26T02:30:16 < rajkosto> i tried leaving the box empty in the symbol pad mapping but it doesnt fix it
2019-01-26T02:30:58 < rajkosto> https://images.sshnuke.net/2019-01-26_01-30-56_N72pgcxc7.png
2019-01-26T02:31:34 < englishman> good question
2019-01-26T02:32:28 < englishman> just make another sch symbol
2019-01-26T02:32:30 < englishman> i guess
2019-01-26T02:33:38 < rajkosto> oh lord oh man
2019-01-26T02:46:52 < Cracki> you do that cable by doing a sweep or whatever it calls that. draw the bent profile
2019-01-26T02:47:40 < Cracki> make it from pieces. straight and curved.

2019-01-26T05:19:10 < rajkosto> make a reverse version of the footprint or just swap it in the schematic

2019-01-26T06:35:34 < PeterM> full of aidsfruit tarduino bloggers
2019-01-26T06:36:53 < rajkosto> so the pins for the connector on one of the boards has to be reversed, do i do it in the schematic or do i make a mirrored footprint
2019-01-26T06:37:19 < PeterM> both
2019-01-26T06:37:44 < PeterM> make a new footprint with the pins mirrored and the correct 3d model on the rear of the board
2019-01-26T06:37:55 < PeterM> and make a new sch part for the new footprint

2019-01-26T06:37:58 < rajkosto> but then nothing needs to hapepn in the schematic
2019-01-26T06:38:00 < rajkosto> 1 stays 1
2019-01-26T06:38:36 < rajkosto> unless you care about which side the pins are on in the symbol
2019-01-26T06:39:09 < PeterM> you should use a new sch part with the new footprint, instead of using  the alternate footprint for the same symbol
2019-01-26T06:39:13 < rajkosto> but if thats the case it would be for readability, not actually correspond to the footprint used
2019-01-26T06:39:49 < rajkosto> but its the same part 
2019-01-26T06:39:56 < rajkosto> why would it need 2 symbols 
2019-01-26T06:41:07 < PeterM> you can use one symbol with alternate footprints, but there is risk of accidentally selecting the footprint with the wrong assembly
2019-01-26T06:41:32 < rajkosto> if i do what you said with the footprint, and make it default bottom instead of default top, it would be pretty obvious
2019-01-26T06:41:32 < tjq> cuck grenade 
2019-01-26T06:41:44 < PeterM> like i have two footprints and 2 sch parts for the same caps, but mounted vertically and right angle
2019-01-26T06:42:13 < rajkosto> then whats the point of letting you select more than 1 footprint per symbol
2019-01-26T06:42:31 < PeterM> for different placement densities
2019-01-26T06:43:55 < PeterM> sometimes i have the same footprint but with no silk, i use it for that too
2019-01-26T06:43:55 < rajkosto> thats too pro

2019-01-26T08:54:09 < rajkosto> yes.
2019-01-26T08:54:15 < rajkosto> knocked that shit off in the 80s
2019-01-26T08:54:33 < rajkosto> when the dolla bills started having about 20 zeroes
2019-01-26T08:54:35 < rajkosto> with one more zero every day
2019-01-26T08:54:42 < rajkosto> but i wasnt born then
2019-01-26T08:55:24 < rajkosto> anyway it didnt seem to be military-murderin-civilians socialism
2019-01-26T08:55:29 < rajkosto> but "nobody really works yet they still get paid" socialism
2019-01-26T08:56:18 < Cracki> btw huffpost/buzzfeed fired dozens of hacks because they weren't even worth their shit gender studies degrees anymore
2019-01-26T08:56:26 < Cracki> so... hooray capitalism
2019-01-26T08:56:27 < rajkosto> nah
2019-01-26T08:56:39 < rajkosto> just plausible deniability

2019-01-26T14:19:20 < marble_visions> i can't seem to word my question correctly to google, but is there a standard library or header that includes names of non-character bytes of ascii?
2019-01-26T14:22:16 < BrainDamage> so you want an ascii table?
2019-01-26T14:22:42 < marble_visions> BrainDamage: yes, but specifically the control symbols
2019-01-26T14:22:58 < BrainDamage> get a full one and trim the unwanted stuff
2019-01-26T14:23:38 < specing> marble_visions: ASCII.HT? ASCII.NUL, ...?
2019-01-26T14:23:48 < marble_visions> specing knows.
2019-01-26T14:24:08 < specing> why do you want to trim one?
2019-01-26T14:24:17 < specing> you can use it in ZFP just fine
2019-01-26T14:24:26 < marble_visions> i can always roll my own out, but was wondering if there's already one in a standard place
2019-01-26T14:24:49 < marble_visions> specing: it's a c-only project, so I can't
2019-01-26T14:25:20 < marble_visions> well, i could, but i'll be entering in a world of hurt with a mixed language project
2019-01-26T14:26:39 < specing> my condolences :D
2019-01-26T14:27:21 < specing> you can't use escape codes \n \r?
2019-01-26T14:28:16 < jpa-> marble_visions: i'm not aware of such standard library
2019-01-26T14:28:40 < marble_visions> i would rather work with value representations instead of escape codes. seems cleaner that way. seems like a custom header with ASCII_ defines is the way to go
2019-01-26T14:29:07 < jpa-> who cares about the names anyway?
2019-01-26T14:30:05 < specing> marble_visions: const char nl = '\n';
2019-01-26T14:30:07 < specing> ?
2019-01-26T14:30:25 < jpa-> very few control codes are used for their original uses anymore; #define ASCII_LF 0x0A  #define ASCII_CR 0x0D  will get you far
2019-01-26T14:30:44 < jpa-> though IMO just '\n' and '\r' are clearer
2019-01-26T14:31:11 < marble_visions> jpa-: i'm writing against a spec that uses their original names so i'd rather stick to that
2019-01-26T14:31:14 < specing> marble_visions: oh I just realized this was ##stm32 :)
2019-01-26T14:31:31 < marble_visions> specing: indeed
2019-01-26T14:32:05 < jpa-> marble_visions: ok
2019-01-26T14:32:24 < marble_visions> i liked the idea of getting away from defines, but i got into an issue with the compiler and went back to them
2019-01-26T14:32:41 < marble_visions> specing: ^
2019-01-26T14:33:10 < marble_visions> so #define ASCII_BLAH it is 
2019-01-26T14:34:30 < specing> hmm, could une put type information into define? E.g. #define nl ((char)'\n')
2019-01-26T14:34:49 < specing> not sure if it would help much, given the laissez-faire nature of C
2019-01-26T14:38:56 < jpa-> it will become int as soon as you touch it anyway

2019-01-26T16:25:04 < zyp> you can just use an untyped enum

2019-01-26T17:23:12 < bitmask> only had one heater and one battery pack, set to 130F for an hour, battery went from 12.5V to 11.7V
2019-01-26T17:24:40 < invzim> what could possibly go wrong.. :)
2019-01-26T17:24:51 < bitmask> I could get much warmer :P
2019-01-26T17:32:43 < specing> bitmask: you must make the highest setting be 'fire'
2019-01-26T17:34:49 < bitmask> theres no setting for that, your are just lucky if you happen to attain that setting
2019-01-26T17:35:13 < bitmask> so 1 battery pack with 4 heaters would last about an hour, thats pretty good
2019-01-26T17:35:22 < bitmask> on high setting

2019-01-26T17:38:41 < bitmask> the batteries arent even close to drawing their rated current
2019-01-26T17:39:05 < specing> bitmask: which batteries are these?
2019-01-26T17:39:10 < bitmask> they are 20-30A batteries and drawing a few amps at most

2019-01-26T17:40:47 < specing> LG iirc
2019-01-26T17:40:56 < bitmask> yea those are one of the ones im lookin at
2019-01-26T17:41:03 < bitmask> lg is correct
2019-01-26T17:41:24 < bitmask> $4.50 - $5 a piece if I recall correctly
2019-01-26T17:43:22 < specing> sounds expensive. They shouldn't be more than $3, esp. if you buy 10+ of them
2019-01-26T17:43:44 < bitmask> theres no way they are $3 a piece
2019-01-26T17:43:58 < bitmask> maybe in quantity but I only need 3 or 6
2019-01-26T17:44:40 < specing> ah yes, they are 4 eur in qty 1 from nkon
2019-01-26T17:45:22 < bitmask> I can get 2600 mah low current ones for $3

2019-01-26T18:22:14 < marble_visions> it's safer than c and formal verification is less painful compared to frama-c's rte+wp

2019-01-26T18:25:01 < marble_visions> better syntax (least so for expressing proper constants in base 2, 8, 10 and 16), better type system, more stuff built in the language itself
2019-01-26T18:25:57 < jadew> I'll have to read up on it
2019-01-26T18:26:19 < jadew> I haven't changed languages in quite a long time
2019-01-26T18:26:37 < jadew> (not planning to either, but I guess it's good to know what's available)
2019-01-26T18:28:09 < marble_visions> chances are you won't be mindblown, but ada does some stuff in a different way from the mainstream langs
2019-01-26T18:29:21 < specing> it detects a lot of bugs in the compile phase that C/C++ will never catch and detects a ton more with the extensive run-time checks
2019-01-26T18:30:00 < specing> for example I have a integer print procedure where I checked if input is negative, then negated it and started the division loop
2019-01-26T18:30:57 < specing> with Ada there was a runtime check generated (and a warning printed by compiler) for this input being the lowest possible integer

2019-01-26T18:41:07 < marble_visions> specing: you can do formal in C as well, but it's more difficult initially. however wp allows for function pointers (spark doesn't, although i don't know how they are treated in analysis)
2019-01-26T18:42:26 < specing> Right now my bug-elimination consists of looking at the disassembly for calls to the program-wide exception handler
2019-01-26T18:42:38 < specing> then changing my code until no such calls are generated any more
2019-01-26T18:43:21 < specing> so I'm more or less guaranteed that there will be no array bounds violations, arithmetic overflows, type conversion errors et cetera

2019-01-26T19:21:57 < specing> the final calls can be uniquely matched to the file and line number, so it shoudn't be hard to supress redundant warnings

2019-01-26T19:22:14 < mawk> you can make a PR too
2019-01-26T19:22:21 < specing> but it would require modifications to the compiler, doing an external tool for this would be silly

2019-01-26T22:11:03 < jadew> bitmask, BrainDamage is on to something, a warmed fleshlight could sell
2019-01-26T22:12:02 < bitmask> not a bad idea but since guys cum in like 3 seconds you might as well just soak it in hot water for a few min first :P

2019-01-26T22:12:22 < jadew> good point
2019-01-26T22:12:51 < rajkosto> jadew, these already exist
2019-01-26T22:13:04 < jadew> oh
2019-01-26T22:13:10 < rajkosto> theres also super cheap "onahole warmers" for normal ones
2019-01-26T22:13:28 < jadew> by normal ones you mean live ones?
2019-01-26T22:13:45 < rajkosto> the ones that are just a slab of silicone
2019-01-26T22:13:49 < jadew> ah
2019-01-26T22:13:57 < rajkosto> live ones should already be heated or youre doing something very wrong
2019-01-26T22:13:59 < jadew> thought you mean there are pussy warmers

2019-01-26T22:37:26 < Ecco> Heya
2019-01-26T22:37:36 < Ecco> I'm looking for 3.2 x 2.5 mm crystals
2019-01-26T22:38:08 < Ecco> For some reason, on Farnell, the lowest freq they have at this package is 12 MHz
2019-01-26T22:38:27 < Ecco> I'd rather like 4 or 8 MHz
2019-01-26T22:38:37 < Ecco> should I expect to find any at this size?
2019-01-26T22:39:15 -!- gnom [~aleksande@178.150.7.153] has joined ##stm32
2019-01-26T22:40:05 < Thorn> Ecco: I've been told they exist but I haven't seen any personally
2019-01-26T22:40:17 < Ecco> ok
2019-01-26T22:40:29 < Ecco> What's the most common size for 4 or 8 MHz crystal?
2019-01-26T22:41:38 < rajkosto> the cheapest ones are the metal can types
2019-01-26T22:41:59 < englishman> 5x3.2 iirc
2019-01-26T22:42:07 < englishman> well the smallest common
2019-01-26T22:42:18 < rajkosto> if you want small smd packages use 3225 or 3215
2019-01-26T22:42:18 < englishman> the yuge metal can ones are definitely the cheapest and therefore most common
2019-01-26T22:42:28 < englishman> what's the application
2019-01-26T22:42:31 < Ecco> interesting
2019-01-26T22:42:37 < rajkosto> https://en.wikipedia.org/wiki/Crystal_oscillator says HC-49/S is most common
2019-01-26T22:42:42 < Ecco> the point of the crystal is to be able to do USB
2019-01-26T22:42:53 < englishman> on stm32?
2019-01-26T22:42:55 < Thorn> here is a 8MHz 3225 https://lcsc.com/product-detail/SMD-Crystals_KDS_DSX321G-8MHz_8MHz-12pF-20ppm_C57131.html
2019-01-26T22:42:56 < Ecco> yes
2019-01-26T22:43:07 < englishman> 12, 16, 24mhz wont work for some reason?
2019-01-26T22:43:12 < rajkosto> https://images.sshnuke.net/2019-01-26_21-43-07_1yLQMk6uh.png here is a 3225 and 3215 next to a stm32
2019-01-26T22:43:15 < englishman> if you want a small xtal
2019-01-26T22:43:35 < Ecco> rajkosto: yeah, I know the size of a 3225, but thanks :)
2019-01-26T22:43:38 < Thorn> so they do exist but they're not common afaict
2019-01-26T22:43:39 < englishman> or use a stm32 with xtalless usb
2019-01-26T22:43:43 < rajkosto> the big one would have taken space for both of those and then more
2019-01-26T22:43:51 < Ecco> I have a circuit ready
2019-01-26T22:43:53 < marble_visions> englishman: ++
2019-01-26T22:44:09 < Ecco> in production, we're running into issues with ST's DFU bootloader
2019-01-26T22:44:16 < Ecco> ST's code auto-detects the crystal
2019-01-26T22:44:26 < Ecco> and fails miserably because the HSI is slightly our of spec
2019-01-26T22:44:27 < Thorn> can you even run stm32 from 4MHz HSE btw?
2019-01-26T22:44:35 < Thorn> isn't it 8...25?
2019-01-26T22:44:38 < Ecco> Thorn: yes. At least that's what the spec says
2019-01-26T22:44:45 < rajkosto> 8 or 12 works best
2019-01-26T22:44:50 < Ecco> Maybe it depends on the model
2019-01-26T22:45:01 < Ecco> Specs for the one I'm using says 4-26
2019-01-26T22:45:18 < Ecco> So like I said, we already have the PCB ready
2019-01-26T22:45:29 < englishman> are you using a 1% xtal or putting totally wrong caps or something
2019-01-26T22:45:37 < Ecco> nope
2019-01-26T22:45:44 < Ecco> the HSI is off
2019-01-26T22:45:55 < Ecco> which is what the STM32 uses to auto-detect the crystal
2019-01-26T22:46:01 < englishman> are you testing at -40C
2019-01-26T22:46:04 < Ecco> so it believes there's a 26 MHz crystal attached
2019-01-26T22:46:06 < Ecco> nope
2019-01-26T22:46:07 < Ecco> room temp
2019-01-26T22:46:10 < englishman> maybe time for a chat with st
2019-01-26T22:46:15 < Ecco> HSI is at 15.4 MHz
2019-01-26T22:46:17 < Ecco> Definitely
2019-01-26T22:46:25 < Ecco> we're having a discussion
2019-01-26T22:46:32 < englishman> cool
2019-01-26T22:46:45 < Ecco> in the meantime, I'm trying to find a workaround / make our design more resilient to HSI errors
2019-01-26T22:46:58 < Ecco> so I'm looking at lower freq crystals
2019-01-26T22:47:07 < englishman> switch to the superior atmega328p maybe
2019-01-26T22:47:31 < Ecco> because ST's bootloader looks for crysals that are an integer number of MHz between 4 and 26
2019-01-26T22:47:55 < Ecco> but 1MHz differece at 25 MHz is a 4% error. 1MHz diff at 4MHz is a 25% error.
2019-01-26T22:48:39 < Ecco> What you said regarding crystal price was interesting
2019-01-26T22:49:01 < rajkosto> the big ones are as cheap as pennies
2019-01-26T22:49:09 < Ecco> Do you have any idea of how cheap we'd talk?
2019-01-26T22:49:41 < Ecco> Currently we pay $0.17 for a 3225
2019-01-26T22:49:51 < rajkosto> thats pretty good
2019-01-26T22:49:53 < Ecco> should we expect a much lower price for a HC-49 one?
2019-01-26T22:50:27 < Ecco> Also, stupid question: wouldn't the pick'n'place have a harder time with larger parts?
2019-01-26T22:50:29 < rajkosto> 5 cents for one at 100pcs ?
2019-01-26T22:50:39 < englishman> thats pretty cheap for an xtal
2019-01-26T22:50:55 < Thorn> 150+ $0.0796 https://lcsc.com/product-detail/SMD-Crystals_Yangxing-Tech-X322512MSB4SI_C9002.html
2019-01-26T22:51:22 < rajkosto> metal case too, nice
2019-01-26T22:51:25 < Thorn> I use these to clock ethernet 
2019-01-26T22:51:29 < Thorn> (iirc)
2019-01-26T22:51:31 < Ecco> Damn
2019-01-26T22:51:34 < Ecco> That's nice
2019-01-26T22:51:48 < englishman> Ecco: no
2019-01-26T22:51:55 < Ecco> why?
2019-01-26T22:51:58 < englishman> if your dicknplace has trouble with can xtals, find a new assembler
2019-01-26T22:52:15 < Ecco> oh, you were replying to the picknplace question :)
2019-01-26T22:52:17 < englishman> yes
2019-01-26T22:52:23 < Ecco> ok, I assumed it wouldn't be a problem, just wanted to make sure
2019-01-26T22:52:24 < Thorn> or maybe not these exact ones, these are 12 not 25MHz lol
2019-01-26T22:52:33 < englishman> as long as they still come on tape of course
2019-01-26T22:52:37 < Ecco> BTW, what's this lcsc.com website?
2019-01-26T22:52:40 < Ecco> englishman: sure
2019-01-26T22:52:51 < rajkosto> Ecco, chinese digikey for international users
2019-01-26T22:52:56 < Ecco> ok
2019-01-26T22:53:08 < Ecco> how relevant are their prices?
2019-01-26T22:53:59 < Ecco> I mean, digikey and friends are always much more expensive than dealing with the supplier directly
2019-01-26T22:54:15 < Ecco> they're very uesful if you want small quantities or need some parts shipped very fast
2019-01-26T22:54:28 < Ecco> but they're virtually useless if you want to estimate the final price of your bom, right?
2019-01-26T22:56:08 < marble_visions> Ecco: about your first few messages, the HSE is out of spec, right? "HSI" was a typo?
2019-01-26T22:56:08 < rajkosto> why are you using a 4MHz xtal anyway
2019-01-26T22:56:17 < Ecco> marble_visions: nope
2019-01-26T22:56:39 < rajkosto> using a 8MHz would probably fix your issue
2019-01-26T22:56:51 < rajkosto> or 12, or 16 or 24 (if supported)
2019-01-26T22:56:51 < Ecco> no, the HSI is out of spec, which trips the DFU bootloader when it auto-configures the HSE
2019-01-26T22:57:07 < Ecco> rajkosto: well, 24 vs 25 wouldn't probably change anything
2019-01-26T22:57:16 < rajkosto> what are you using
2019-01-26T22:57:18 < Ecco> 8 MHz would be a great start
2019-01-26T22:57:20 < Ecco> 25 MHz
2019-01-26T22:57:27 < rajkosto> isnt that out of spec
2019-01-26T22:57:37 < Ecco> nope
2019-01-26T22:57:46 < Ecco> spec says 4..26 MHz
2019-01-26T22:58:06 < Ecco> damn
2019-01-26T22:58:21 < Ecco> I'm really glad I got your advice on this guys
2019-01-26T22:58:32 < Ecco> indeed, SMD crystals are a lot more expensive than HC49
2019-01-26T22:58:50 < rajkosto> but hc49 is huge
2019-01-26T22:59:03 < Ecco> it is
2019-01-26T22:59:09 < Ecco> It's not that bad though
2019-01-26T22:59:18 < Ecco> anyway, I can make it fit in my design I think
2019-01-26T22:59:34 < Ecco> while we're on the topic of crystal prices
2019-01-26T22:59:41 < Ecco> what would be the cheapest way to get the RTC running?
2019-01-26T22:59:44 < rajkosto> for the big crystals make sure theres no massive current spikes returning through the ground plane around it
2019-01-26T22:59:54 < rajkosto> Ecco, the 32.768khz can with legs ?
2019-01-26T22:59:57 < Ecco> rajkosto: you lost me
2019-01-26T23:00:05 < Ecco> rajkosto: "the 32.768khz can with legs " -> Maybe?
2019-01-26T23:00:17 < rajkosto> those are so common
2019-01-26T23:00:22 < marble_visions> right, i need to rtfm to see what the stm bootloader does with the clocks.
2019-01-26T23:00:30 < Ecco> Also, how the hell are those pick-n-placed?
2019-01-26T23:00:36 < rajkosto> theyre not
2019-01-26T23:00:45 < Ecco> so… how are they mounted?
2019-01-26T23:00:52 < rajkosto> chiense sweatshop
2019-01-26T23:01:08 < rajkosto> you probably want the SMD black box ones that are similar size to hc49
2019-01-26T23:01:19 < rajkosto> those are next cheapest
2019-01-26T23:01:29 < rajkosto> https://media.rs-online.com/t_large/F6676117-01.jpg
2019-01-26T23:01:34 < Ecco> Yeah, so it's like 3cents for the crystal + 50 cents for assembly
2019-01-26T23:01:40 < Ecco> oh, ok
2019-01-26T23:01:52 < Ecco> lcsc does indeed say 3 cents for a legged crystal
2019-01-26T23:02:01 < Ecco> boy I had my bom completly wrong on crystals
2019-01-26T23:03:11 < rajkosto> the SMD 49 actually takes up more pcb space but can be pick and placed
2019-01-26T23:03:18 < Ecco> indeed
2019-01-26T23:03:55 < Ecco> well, that being said, if you have good flux I think the two-legged one can be soldered in a matter of seconds
2019-01-26T23:04:11 < Ecco> but it still doesn't look like a dream job
2019-01-26T23:04:18 < rajkosto> oh there are 32.768khz ones in smd 49 too
2019-01-26T23:04:43 < Ecco> well I might not be looking in the right place
2019-01-26T23:04:51 < Ecco> lcsc doesn't give me any
2019-01-26T23:05:07 < Ecco> sure they seem to have far fewer parts than digikey and friends
2019-01-26T23:05:12 < Ecco> but actually I'm looking for common parts
2019-01-26T23:05:18 < Ecco> so that's actually a good thing
2019-01-26T23:05:23 < rajkosto> lcsc has the 3215 32.768khz same price as the bigger smd ones, at 15cents
2019-01-26T23:05:33 < Ecco> yeah
2019-01-26T23:05:45 < rajkosto> https://lcsc.com/product-detail/SMD-Crystals_Seiko-Instruments__Seiko-Instruments-SSP-T7-F-32-768kHz-20PPM-12-5p_C108687.html vs https://lcsc.com/product-detail/SMD-Crystals_EPSON_Q13FC1350000400_FC-135-32-768KHz-20ppm-12-5pF_C32346.html
2019-01-26T23:05:45 < Ecco> 5 times more than the cylinder one
2019-01-26T23:06:06 < rajkosto> both are cheap enough/common enough to be used on bluepill/blackpill boards btw
2019-01-26T23:06:40 < rajkosto> so just use them
2019-01-26T23:06:57 < rajkosto> and 3225 for 12MHz, done
2019-01-26T23:07:12 < Ecco> yeah, but HC49 is a lot cheaper
2019-01-26T23:07:37 < Ecco> Completely unrelated question
2019-01-26T23:07:39 < rajkosto> 5c vs 11c
2019-01-26T23:07:52 < Ecco> how the hell can you pick'n'place on both sides of the PCB??
2019-01-26T23:07:55 < rajkosto> worth having a honking can on your pcb ?
2019-01-26T23:08:01 < rajkosto> Ecco, you pay 3x the price for assembly
2019-01-26T23:08:02 < rajkosto> is how
2019-01-26T23:08:19 < rajkosto> absolutely avoid putting anything on the bottom
2019-01-26T23:08:21 < rajkosto> for that reason
2019-01-26T23:08:35 < rajkosto> other than maybe tht connectors
2019-01-26T23:08:38 < Ecco> yeah, I've just seen that on the bluepill 
2019-01-26T23:08:38 < aandrew> wtf
2019-01-26T23:08:46 < aandrew> double sided SMT assembly is not THAT much more expensive
2019-01-26T23:08:53 < Ecco> apparently those are cheap devices
2019-01-26T23:09:01 < rajkosto> Ecco, they are also massive quantity produced
2019-01-26T23:09:02 < Ecco> but price aside, how can it even work?
2019-01-26T23:09:03 < aandrew> it's only another paste+place+reflow cycle
2019-01-26T23:09:08 < aandrew> Ecco: uh
2019-01-26T23:09:10 < rajkosto> at quantity, the cost goes down
2019-01-26T23:09:18 < aandrew> you paste+place+reflow, flip, do it again
2019-01-26T23:09:20 < Ecco> won't parts fall down on the second reflow cycle?
2019-01-26T23:09:28 < rajkosto> no, they are reflowed first
2019-01-26T23:09:29 < aandrew> you don't put heavy components on the bottom side unless you glue them
2019-01-26T23:09:35 < aandrew> surface tension holds them just fine
2019-01-26T23:09:47 < Ecco> oh, fun
2019-01-26T23:09:50 < BrainDamage> surface tension will have a decent holding capability on its own
2019-01-26T23:10:00 < rajkosto> unless you whack the board, components dont fall off the bottom side
2019-01-26T23:10:01 < BrainDamage> you can also use solders with different melting points
2019-01-26T23:10:10 < Ecco> BrainDamage: ha, good point
2019-01-26T23:14:49 < rajkosto> there can also be a glue squirting pass after the paste pass but before pick and place
2019-01-26T23:14:55 < Ecco> rajkosto: what did you mean about current spikes below the crystal?
2019-01-26T23:15:11 < rajkosto> Ecco, dont let the ground plane below the crystal carry significant return currents
2019-01-26T23:15:20 < Ecco> why not?
2019-01-26T23:15:25 < rajkosto> the crystal is very low voltage and is quite noise sensitive
2019-01-26T23:15:32 < Ecco> ok
2019-01-26T23:15:50 < Ecco> would a larger crystal be more sensitive?
2019-01-26T23:15:57 < rajkosto> theres more ground plane below it
2019-01-26T23:15:59 < rajkosto> is why im saying
2019-01-26T23:16:04 < Ecco> oh, ok :)
2019-01-26T23:16:24 < rajkosto> thats why some pcbs have cuts in the ground plane around the big crystal
2019-01-26T23:16:46 < Ecco> oh, interesting
2019-01-26T23:17:10 < Ecco> that's a good question though: how does current flow in a plane that connects two points?
2019-01-26T23:17:24 < rajkosto> low freqnecy == straight line, high frequency == under the signal
2019-01-26T23:17:41 < Ecco> what does "under the signal" mean?
2019-01-26T23:17:49 < rajkosto> ground plane as close to the signal line
2019-01-26T23:17:54 < rajkosto> usually straigth under it
2019-01-26T23:18:29 < Ecco> oh, ok
2019-01-26T23:18:34 < Ecco> got it
2019-01-26T23:18:35 < Ecco> that's fun
2019-01-26T23:19:43 < Ecco> gotta love chinese engrish

2019-01-26T23:19:52 < Ecco> "Hing reliability is achieved by metal cap"
2019-01-26T23:19:56 < Ecco> Hing reliability :-D
2019-01-26T23:19:59 < rajkosto> anyway for big crystals they either do this https://i.stack.imgur.com/KPKN3.png or this https://images.sshnuke.net/2019-01-26_22-19-57_A21yL0VvD.png
2019-01-26T23:20:20 < Ecco> rajkosto: thank you so much for taking your time to explain this
2019-01-26T23:20:21 < rajkosto> both pretty extreme
2019-01-26T23:20:26 < rajkosto> you can yolo it and hope it works with no cuts though
2019-01-26T23:20:30 < rajkosto> usually does
2019-01-26T23:20:31 < Ecco> First one I understood
2019-01-26T23:20:35 < Ecco> second one not so much
2019-01-26T23:20:37 < Ecco> oh wait
2019-01-26T23:20:45 < rajkosto> cut in plane == return current has to avoid it
2019-01-26T23:20:45 < Ecco> that's just an isolated plane, right?
2019-01-26T23:20:59 < Ecco> is it actually connected to gnd somehow?
2019-01-26T23:21:03 < rajkosto> it is

2019-01-26T23:21:07 < Ecco> first solution seems easier
2019-01-26T23:21:08 < rajkosto> under the XI/XO wires
2019-01-26T23:21:16 < rajkosto> you can also omit the cut to the very right
2019-01-26T23:21:22 < rajkosto> current will still avoid it
2019-01-26T23:21:30 < Ecco> ok
2019-01-26T23:21:35 < Ecco> second screenshot looks like Altium
2019-01-26T23:21:45 < Ecco> can you define "keep-out" areas for polygon pours?
2019-01-26T23:21:45 < rajkosto> yes its a board i hand etched.
2019-01-26T23:21:54 < rajkosto> its called polygon cutout
2019-01-26T23:21:58 < Ecco> Or do you have to define a funky shape for the polygon pour
2019-01-26T23:22:01 < rajkosto> and its exactly what the dashed line rectangels are
2019-01-26T23:22:02 < Ecco> oh, ok, nice
2019-01-26T23:22:05 < Ecco> great
2019-01-26T23:22:06 < Ecco> thanks!
2019-01-26T23:23:08 < rajkosto> why are you even worrying about xtal prices if you are a beginner
2019-01-26T23:24:24 < Ecco> well, parts tend to be so integrated these days that you can get quite a lot of things working even if you suck at actual EE
2019-01-26T23:24:46 < rajkosto> yeah but 20 vs 10 cents doesnt matter at small quantities for messing around 
2019-01-26T23:25:10 < Ecco> sure, but not if you buy a lot :)
2019-01-26T23:25:45 < Ecco> I mean, the board house doesn't give a shit wether your design is good or not
2019-01-26T23:25:55 < Ecco> and even bad design have a great chance of working most of the time
2019-01-26T23:26:32 < Ecco> apparently there are quite a few details I overlooked, and so far didn't run into any trouble
2019-01-26T23:26:40 < Ecco> e.g. trace length matching on quad-spi
2019-01-26T23:26:50 < Ecco> or in this case, avoiding current below a crystal
2019-01-26T23:27:00 < rajkosto> well you ARE having crystal problems
2019-01-26T23:27:03 < Ecco> maybe we had a few boards fail because of that
2019-01-26T23:27:07 < Ecco> oh no
2019-01-26T23:27:08 < Ecco> we don't
2019-01-26T23:27:09 < rajkosto> value too weird/high though is more likely
2019-01-26T23:27:17 < Ecco> no, we really don't
2019-01-26T23:27:22 < Ecco> the crystals are just right
2019-01-26T23:27:31 < Ecco> it's the STM32's HSI that's off
2019-01-26T23:27:49 < Ecco> so it thinks it's hooked to a 26 MHz crystal when in reality it's hooked to a 25 one
2019-01-26T23:29:28 < Ecco> anyway
2019-01-26T23:29:34 < Ecco> it's true that HC49 are huge
2019-01-26T23:29:57 < Ecco> they didn't look that big on the bluepill picture
2019-01-26T23:30:40 < rajkosto> larger than the chip + pins
2019-01-26T23:30:54 < Ecco> yeah, true

2019-01-27T00:29:07 < jadew> Ecco, you don't need length matching for SPI
2019-01-27T00:29:31 < jadew> unless you're doing really high frequency or your lines are extremely off
2019-01-27T00:29:46 -!- machinehum [~machinehu@ip-142-232-166-215.ptr.bcit.ca] has joined ##stm32
2019-01-27T00:34:06 < jadew> I just did the math on this, with a clock speed of 10 MHz, your traces could be different by as much as 7 meters and it would still work
2019-01-27T00:34:36 < machinehum> For?
2019-01-27T00:34:41 < jadew> for SPI
2019-01-27T00:34:48 < machinehum> At what f
2019-01-27T00:34:55 < jadew> 10 MHz clock speed
2019-01-27T00:35:22 < machinehum> That's just for signal timing?
2019-01-27T00:35:26 < jadew> yeah
2019-01-27T00:35:48 < jadew> this was about how length matching is not necessary
2019-01-27T00:35:48 < machinehum> I mean parasitic inducatace will fuck you before
2019-01-27T00:36:19 < machinehum> Guess I should stop length matching like a pussy
2019-01-27T00:36:42 < rajkosto> spi can go up to 80-100MHz for common serial falsh
2019-01-27T00:36:49 < qyx> how did you get 7m?
2019-01-27T00:36:58 < machinehum> c bro
2019-01-27T00:37:00 < rajkosto> just length match to 10mm and its fine
2019-01-27T00:37:22 < jadew> qyx, c / 10e6 * FR-4 velocity factor
2019-01-27T00:38:24 < qyx> thats about 30m for 100ns not considering velocity factor
2019-01-27T00:38:32 < qyx> but yeah, thats for the whole clock cycle
2019-01-27T00:38:37 < rajkosto> halve it
2019-01-27T00:38:43 < qyx> ok, fair enough
2019-01-27T00:38:46 < BrainDamage> you want 1/10, not 1/2
2019-01-27T00:39:00 < BrainDamage> but even then it'd be 3m
2019-01-27T00:39:16 < jadew> yep and if you divide it, you get the half cycle by when the signal has to be stable
2019-01-27T00:39:23 < machinehum> I've never actually length matched for SPI...
2019-01-27T00:39:31 < jadew> BrainDamage, what do you mean?
2019-01-27T00:39:33 < machinehum> Only for a parallel ram chip
2019-01-27T00:39:45 < jadew> c / 10e6 * vf = 14.4 meters
2019-01-27T00:39:55 < BrainDamage> jadew: a whole wavelength of delay is a 360 deg rotation
2019-01-27T00:39:58 < jadew> divided by 2, for the half cycle, you get 7 m
2019-01-27T00:40:01 < BrainDamage> signal gets fucked already at 1/4 rotation
2019-01-27T00:40:20 < BrainDamage> because it's a 90 deg phase shift
2019-01-27T00:40:42 < BrainDamage> and it's linear with phase, so you want even less than 90 deg
2019-01-27T00:40:51 < BrainDamage> ideally you want say, 20-30 deg rotation max
2019-01-27T00:41:16 < BrainDamage> hence why, 1/4 to get 90 deg, *1/2 to get to 45, and some extra margin gives you 1/10

2019-01-27T00:41:56 < jadew> what fucks it by 1/4?
2019-01-27T00:42:07 < machinehum> Hey has anyone ever designed a 400Mhz antenna that is 4cm long?
2019-01-27T00:42:25 < BrainDamage> jadew: a 90 deg phase shift is a lot
2019-01-27T00:42:39 < jadew> BrainDamage, yeah, but does it have to ruin the signal?
2019-01-27T00:42:58 < BrainDamage> for analog consider it's a completely different orthogonal base
2019-01-27T00:43:09 < jadew> you'd get transmission line effects... so if it's well designed, shouldn't it survive the trip?
2019-01-27T00:43:15 < BrainDamage> there's whole modulations built upon that a 90 deg phase shift is an orthogonal shift
2019-01-27T00:43:40 < BrainDamage> no, more like the sampling crap at the ic won't see a stable signal
2019-01-27T00:44:35 < BrainDamage> machinehum: if you're doing a 4cm antenna it's electrically short, it means your performance will be sub-optimal, but it's doable
2019-01-27T00:44:45 < BrainDamage> machinehum: a "rubber ducky" pattern will work
2019-01-27T00:45:34 < jadew> BrainDamage, can you please elaborate on the previous topic please? what would destroy the signal?
2019-01-27T00:45:51 < BrainDamage> jadew: are you familiar with odd-even signal analysis?
2019-01-27T00:45:58 < machinehum> BrainDamage: Wavelength is like 18cm or something
2019-01-27T00:46:01 < BrainDamage> also called common mode and differential
2019-01-27T00:46:17 < jadew> I am not
2019-01-27T00:46:18 < machinehum> We want like a -3db antenna
2019-01-27T00:46:25 < BrainDamage> machinehum: wavelength is 78cm, 1/4 lambda is 18cm
2019-01-27T00:46:57 < machinehum> So you could get 0db with 18cm and enough gnd
2019-01-27T00:47:18 < BrainDamage> a 18cm antenna is a marconian antenna, which has 6db gain
2019-01-27T00:47:23 < BrainDamage> jadew: it's a direct application of superposition, you can decompose any pair of generators into odd-even pair
2019-01-27T00:47:35 < BrainDamage> jadew: one is a common mode one, another is a differential
2019-01-27T00:48:04 < BrainDamage> this produces symmetries in the circuit, which let you analyse it easier
2019-01-27T00:48:11 < jadew> I'll have to read up on it
2019-01-27T00:48:13 < BrainDamage> eg common mode caps disappear under differential signal, etc
2019-01-27T00:48:24 < BrainDamage> the result is that you get 2 different char impedances
2019-01-27T00:48:44 < BrainDamage> one on common mode, another on differential
2019-01-27T00:49:45 < jadew> is this relevant only for this low frequency and because of the relatively big length of trace we were speaking about?
2019-01-27T00:50:07 < BrainDamage> calculate the reflection coefficient with a gamma that implies a rotation of 90°, and you'll see that very little signal ends up at your pin
2019-01-27T00:50:17 < BrainDamage> no, it can be applied at any freq
2019-01-27T00:50:22 < machinehum> BrainDamage: Is a -3db antenna possible in 4cm? You know RF because I sure don't.
2019-01-27T00:50:49 < BrainDamage> jadew: small or big of circuit is only relative to the wavelength
2019-01-27T00:51:08 < jadew> BrainDamage, is that assuming that the input pin is of a different impedance than the TL?
2019-01-27T00:51:17 < BrainDamage> the output will be
2019-01-27T00:51:22 < BrainDamage> because of the mismatch
2019-01-27T00:52:21 < BrainDamage> machinehum: it miiight be possible
2019-01-27T00:52:31 < BrainDamage> but it's kinda stretching it
2019-01-27T00:52:42 < machinehum> Do you have sim software?
2019-01-27T00:52:51 < machinehum> Because there's bitcoin in it for you.
2019-01-27T00:52:58 < BrainDamage> yes, I have a sim
2019-01-27T00:56:16 < machinehum> But serious how much would you charge for your "best shot"
2019-01-27T00:59:08 < BrainDamage> I'm rather rusty in antenna design, you might want someone else
2019-01-27T00:59:55 < machinehum> Fine I'll go find someone else on a random IRC channel

2019-01-27T01:12:24 < englishman> and, unless you are buying millions of parts, distributors are pretty much how you will be buying stuff
2019-01-27T01:12:50 < englishman> even then, probably distributors
2019-01-27T01:18:07 < BrainDamage> machinehum: https://www.digikey.com/product-detail/en/linx-technologies-inc/ANT-433-HETH/ANT-433-HETH-ND/625468
2019-01-27T01:18:44 < machinehum> Tried it
2019-01-27T01:20:45 < BrainDamage> I would say to crawl digikey, there's plenty of readily made coil ( rubber ducky ) antennas you can slap on your pcb
2019-01-27T01:21:11 < machinehum> The problem is
2019-01-27T01:21:25 < machinehum> The amount of gnd you need on your pcb is massive
2019-01-27T01:21:52 < machinehum> For instance look at this guy
2019-01-27T01:21:54 < machinehum> https://www.digikey.com/product-detail/en/linx-technologies-inc/AEK-433-USP/AEK-433-USP-ND/3830744
2019-01-27T01:22:50 < machinehum> Like yeah you antenna is 12mm long... the PCB that you've done your testing on is 20cm...
2019-01-27T01:22:55 < machinehum> your*
2019-01-27T01:23:03 < BrainDamage> that's why I suggested a coil antenna
2019-01-27T01:23:17 < BrainDamage> you DON'T want ground planes under the antenna
2019-01-27T01:23:45 < BrainDamage> see my link's datashit
2019-01-27T01:23:56 < machinehum> There are no gain plots for that part though
2019-01-27T01:24:08 < machinehum> Yeah I got the link thanks :)
2019-01-27T01:24:27 < BrainDamage> it offers a max gain and a VSWR
2019-01-27T01:24:44 < BrainDamage> if you assume that the losses are constant in freq for your region
2019-01-27T01:24:58 < BrainDamage> then flip the VSWR and you got your gain plot
2019-01-27T01:25:33 < BrainDamage> in particular, you can turn VSWR into gamma ( reflection coefficient )
2019-01-27T01:25:47 < BrainDamage> gamma^2 gives you % of reflected power
2019-01-27T01:26:13 < BrainDamage> is this a tx antenna?
2019-01-27T01:26:17 < machinehum> Yes
2019-01-27T01:26:32 < BrainDamage> typical acceptable vswr for tx'ing is 2:1
2019-01-27T01:26:41 < BrainDamage> which corresponds to about 10% of reflected power
2019-01-27T01:26:55 < BrainDamage> which you can see indicated in the graph
2019-01-27T01:28:03 < machinehum> I mean don't you still need a ton of gnd for these guys? Because it's technically the other side of a dipole?
2019-01-27T01:28:25 < machinehum> Keep in might I don't really know what I'm talking about
2019-01-27T01:29:54 < BrainDamage> yes, but you can reduce the ground size and get just reduced performance
2019-01-27T01:30:35 < BrainDamage> also that ground plane is part of your circuit anyway
2019-01-27T01:30:49 < BrainDamage> what's your pcb size?
2019-01-27T01:30:52 < machinehum> Ideally I want to keep that performance
2019-01-27T01:31:00 < machinehum> < 40cm x 40cm
2019-01-27T01:31:15 < BrainDamage> that's more than enough
2019-01-27T01:31:29 < BrainDamage> lambda/4 ground plane size is sufficient
2019-01-27T01:31:40 < BrainDamage> yours reaches more than lambda/2
2019-01-27T01:31:58 < machinehum> I thought lamdba/4 was 18cm?
2019-01-27T01:32:07 < BrainDamage> yes, and yours is 40
2019-01-27T01:32:11 < BrainDamage> which is more than twice
2019-01-27T01:32:17 < machinehum> Shit sorry.
2019-01-27T01:32:21 < machinehum> 40mm x 40mm
2019-01-27T01:32:30 < machinehum> My bad.
2019-01-27T01:32:59 < BrainDamage> ok, yes, that'll reduce performance considerably
2019-01-27T01:33:16 < BrainDamage> you'll have to sim to know
2019-01-27T01:34:20 < machinehum> Is there any magic? Our BOM target is unlimited
2019-01-27T01:34:31 < machinehum> Like crazy materials
2019-01-27T01:35:11 < BrainDamage> the higher the dielectric and the magnetic constants, the smaller you can make your shit
2019-01-27T01:35:25 < BrainDamage> or you could use two of those
2019-01-27T01:35:37 < BrainDamage> you don't strictly need ground as a counterpoise
2019-01-27T01:35:41 < machinehum> Yeah I found some shit like that ... Really expensive materials which is okay
2019-01-27T01:35:53 < BrainDamage> you can use another and form a helical dipole
2019-01-27T01:36:09 < machinehum> Cool
2019-01-27T01:36:14 < BrainDamage> it won't be as omni as a single one, but it could be acceptable
2019-01-27T01:36:21 < BrainDamage> however, again, you'll need to sim

2019-01-27T03:31:48 < bitmask> can I get some physics help?
2019-01-27T03:32:08 < bitmask> basic electricity stuff
2019-01-27T03:32:53 < bitmask> if I have multistrand carbon fiber and have it connected at both ends to regular wire, does it matter if the strands are touching throughout the path?
2019-01-27T03:33:12 < bitmask> if I split it into say two sets of paths does it change anything?
2019-01-27T03:34:23 < mawk> I don't know the resistance of that wire bitmask 
2019-01-27T03:34:28 < mawk> but I guess it's non negligible
2019-01-27T03:34:37 < bitmask> 9 ohms per meter
2019-01-27T03:34:38 < mawk> it all depends on the current you're planning
2019-01-27T03:34:39 < rajkosto> cant win, if i export to parasolid to try and get copper traces, i get unfolded board, with step i get folded but no copper
2019-01-27T03:35:14 < mawk> if you split the two wires with exactly the same number of strands in them it should be okay bitmask 
2019-01-27T03:35:39 < BrainDamage> bitmask: draw the thing
2019-01-27T03:36:06 < bitmask> but I dont need numbers, just say I have it all together and it draws 2 amps, if I keep it connected at the ends but just pull it apart in the middle to 'draw' two separate paths with it, will it still draw 2 amps and just be in a ratio of however many strands are in each path
2019-01-27T03:36:47 < Cracki> bitmask, consider: wherever they touch, they'd have the same voltage potential there, right?
2019-01-27T03:36:56 < Cracki> (before touching, of course)
2019-01-27T03:37:33 < Cracki> model it as four resistors, two series, two parallel
2019-01-27T03:37:41 < Cracki> nothing will happen
2019-01-27T03:38:25 < Cracki> things would happen if the near-beginning of one strand touched the near-end of the other... then you'd have a very short current path
2019-01-27T03:38:42 < bitmask> I guess I'm more wondering about how electrons flow, is it by cross sectional area or does it mostly travel on the surface so surface area, I guess that doesnt really make sense
2019-01-27T03:39:01 < mawk> the surface thing is for AC
2019-01-27T03:39:01 < Cracki> for hf, "skin effect"
2019-01-27T03:39:06 < bitmask> ahh
2019-01-27T03:39:06 < Cracki> for dc, all through
2019-01-27T03:39:16 < mawk> I computed it in school, but I don't remember
2019-01-27T03:39:24 < bitmask> ok so then its just like having thousands of resistors in parallel so I'm good
2019-01-27T03:40:01 < mawk> splitting in two will double the resistance, no ?
2019-01-27T03:40:08 < mawk> that's another thing you might be concerned about
2019-01-27T03:40:20 < bitmask> its all still connected together at the ends
2019-01-27T03:40:24 < Cracki> 2R but two strands, so again R
2019-01-27T03:40:29 < mawk> yes
2019-01-27T03:40:38 < Cracki> makes no diff how you slice the current carrier
2019-01-27T03:40:39 < mawk> if it's exactly the same strands the current will just halve properly
2019-01-27T03:40:48 < mawk> but if they are not symmetrical something bad could happen no ?
2019-01-27T03:40:50 < bitmask> so each strand has double the resistance but half the current so it totals the same
2019-01-27T03:40:57 < mawk> yes, if they're the same cross section
2019-01-27T03:41:01 < Cracki> only worry should be if strands touch so that the current path is actually shortened
2019-01-27T03:41:07 < bitmask> right
2019-01-27T03:41:09 < bitmask> ok
2019-01-27T03:41:15 < mawk> if they touch it's at the same length from start as you said, it should be fine
2019-01-27T03:42:10 < bitmask> I just want to reduce the hotspots without using more carbon fiber, thus increasing resistance. so I was gonna spread the strands out
2019-01-27T03:42:20 < bitmask> so as long as I dont create shorts I"m good
2019-01-27T03:42:55 < BrainDamage> slather them in silicone
2019-01-27T03:43:00 < Cracki> yeah spread'em
2019-01-27T03:43:04 < bitmask> thats what I'm doing
2019-01-27T03:43:34 < bitmask> 1mm sheet on bottom, spread thin layer of silicone adhesive on top, lay it out, then plot another 1mm on top
2019-01-27T03:43:41 < BrainDamage> more silicone than a washed out 60yo diva
2019-01-27T03:44:10 < BrainDamage> oh btw, make sure you have short circuit protection at the battery
2019-01-27T03:44:28 < BrainDamage> with movement and rubbing around, the insulation of the wires from the batteries might wear out and short
2019-01-27T03:45:14 < bitmask> I do
2019-01-27T03:45:51 < bitmask> short circuit and over current @ 10A and over discharge

2019-01-27T07:06:34 < aandrew> what did you do to reduce the thickness? just different silicone?
2019-01-27T07:11:00 < Cracki> sheets of silicone instead of a mold
2019-01-27T07:11:22 < bitmask> yea I 3d printed a mold I designed and then just filled it with silicone caulk
2019-01-27T07:11:47 < bitmask> this time I just bought 1mm thick sheet of silicone and then used silicone adhesive to sandwich everything together
2019-01-27T07:13:59 < bitmask> also for the mold, one of the reasons I made it thick was to hold magnets in the corners which were 3mm thick (so 3mm + 1mm on each side to hold in place), but that was a stupid idea

2019-01-27T15:05:21 < kakimir> sweet I'm still under the blanket
2019-01-27T15:14:28 < antto> wut'cha doin' there?
2019-01-27T15:15:26 < dongs> zyp, do i need to cast all of them
2019-01-27T15:16:42 < kakimir> I don't know antto, watching repair videos for DC3
2019-01-27T15:17:17 < antto> kakimir so, wut kind of switching regulator would you recommend, since you laughed at the mc33063 sorta
2019-01-27T15:20:35 < kakimir> basically anything else

2019-01-27T15:23:56 < jpa-> mc33063 is quite inefficient and outdated, but is there something else wrong with it?
2019-01-27T15:25:12 < antto> jpa- i had to get familiar with it because my collegue had chosen it (no idea how), so i read about it but more importantly - i found a nifty online calculator for it
2019-01-27T15:25:34 < antto> don't know much about other similar regulators (i'm sure there are thousands)
2019-01-27T15:26:03 < jpa-> there are, and "basically anything else" is not a good rule because there are a lot worse choices
2019-01-27T15:27:19 < jpa-> https://github.com/karlp/zypsnips/blob/master/regs-stepdown.txt
2019-01-27T15:28:16 < antto> mm, the nifty thing about mc33063 is that iirc it supports multiple scenarios - boost, buck, inverting
2019-01-27T15:28:36 < antto> in my case i was using it as inverting
2019-01-27T15:29:00 < jpa-> yeah, does many things and nothing particularly well
2019-01-27T15:29:59 < antto> a gud balance then ;P~

2019-01-27T15:51:11 < kakimir> high Iq
2019-01-27T15:51:23 < kakimir> no thermal protection
2019-01-27T15:53:10 < kakimir> and in 2019 you probs get better chips for same or lower price to do the job in high volume products
2019-01-27T15:53:27 < antto> it's not a high-volume product
2019-01-27T15:57:30 < zyp> dongs, yes
2019-01-27T15:58:02 < zyp> for 32-bit you wouldn't need to, since operations like that automatically gets promoted to 32-bit

2019-01-27T20:03:17 < zyp> kitchen update, got up the section with appliances: https://bin.jvnv.net/file/PoGWT.jpg
2019-01-27T20:04:02 < malinus> the fuck you need two ovens for
2019-01-27T20:04:25 < zyp> top one is microwave
2019-01-27T20:04:45 < BrainDamage> props for the consistent aesthetic
2019-01-27T20:04:59 < malinus> looks expensive
2019-01-27T20:05:56 < zyp> expensive is relative
2019-01-27T20:06:19 < BrainDamage> appliances last you 15-20 years
2019-01-27T20:06:35 < BrainDamage> 100-200 bucks more get amortized over a decade
2019-01-27T20:06:47 < Steffanx>  \o/
2019-01-27T20:07:18 < BrainDamage> might as well get something decent, that will feel better to use and possibly have less failures
2019-01-27T20:07:18 < Steffanx> Where does the excess heat of the ovens go?
2019-01-27T20:07:28 < zyp> I hadn't really planned on picking up those appliances until later, but ikea all of a sudden had 20% off on appliances, so I figured I might as well just pick up everything at once: https://bin.jvnv.net/file/h2h6B.jpg
2019-01-27T20:07:55 < zyp> paid around €2500 in total
2019-01-27T20:08:01 < BrainDamage> is that an horizontal fridge?
2019-01-27T20:08:23 < zyp> on the photo it's horizontal, it's kinda hard to transport standing up :p
2019-01-27T20:08:37 < Steffanx> Its behind the black doors i guess?
2019-01-27T20:08:40 < Steffanx> both
2019-01-27T20:08:49 < zyp> yeah
2019-01-27T20:09:16 < zyp> excess heat from the ovens seems to mostly be vented out the front
2019-01-27T20:09:30 < zyp> but there's also vents in the back of the cabinets, all the way from the bottom to the top
2019-01-27T20:09:51 < malinus> Nah, always get the chepeast stuff. That's the only non-brainlet way to save money. It will still last you years.

2019-01-27T20:12:55 < malinus> zyp: retirement by 40. I want to sail around the worth with wife and kids.
2019-01-27T20:13:18 < englishman> i thought 15-20 years was optimistic but we've had this washer-dryer for 10 years and this microwave for 15 though the microwave set on fire this month, it's time for another
2019-01-27T20:14:02 < englishman> in that case, wouldnt resale value be important for you
2019-01-27T20:14:07 < englishman> when you go in that offloading stage
2019-01-27T20:14:29 < englishman> i have a family member who is leaving on that trip in 2 years and is starting to reduce his inventory of stuff
2019-01-27T20:15:55 < malinus> we don't have anything to offload
2019-01-27T20:17:13 < englishman> when will you leave?
2019-01-27T20:18:13 < englishman> so you are a liveaboard now?
2019-01-27T20:18:37 < malinus> we live in a tiny appartment, and are looking for a (bigger) boat.

2019-01-27T20:24:54 < malinus> massive consumerism culture make you think it's impossible, eh?
2019-01-27T20:25:12 < malinus> funny considering the shitload of money we make
2019-01-27T20:28:36 < Steffanx> idk about your "shit load" :P
2019-01-27T20:29:34 < malinus> * assuming you live in the west and work in IT
2019-01-27T20:31:23 < zyp> it's easy enough to retire early, just grab your savings and move to a third world country
2019-01-27T20:32:03 < zyp> but then again, then you have to live in a third world country
2019-01-27T20:32:19 < malinus> indeed
2019-01-27T20:32:21 < Steffanx> but 25+ years early...
2019-01-27T20:32:32 < Steffanx> assuming it's also 65+ for malinus
2019-01-27T20:33:02 < malinus> 65? It's gonna be 75
2019-01-27T20:33:10 < Steffanx> Yes, probably.
2019-01-27T20:33:19 < Steffanx> makes me wonder what country mr malinus is in
2019-01-27T20:33:19 < emeb> any usb gurus here?
2019-01-27T20:33:25 < zyp> sup?
2019-01-27T20:33:33 < malinus> Steffanx: dk
2019-01-27T20:33:40 < emeb> trying something that's probably silly - 
2019-01-27T20:33:48 < emeb> making a usb -> spi bridge
2019-01-27T20:33:50 < zyp> malinus, oh, you're in .dk? whereabouts?
2019-01-27T20:34:06 < emeb> using F042 in CDC class just to carry raw bytes.
2019-01-27T20:34:29 < zyp> emeb, yeah?
2019-01-27T20:34:56 < emeb> I send data from a host app to CDC endpoint in bundles of 64 bytes but it seems like some extra data is being inserted into stream.
2019-01-27T20:35:31 < zyp> ACM seems a bit inconvenient for SPI since that's just giving you a bytestream
2019-01-27T20:35:48 < emeb> yes, I parse out some header info
2019-01-27T20:36:00 < emeb> start of pkt + 4 bytes length
2019-01-27T20:36:11 < zyp> I'd prefer using framing coupled to chip select control
2019-01-27T20:36:12 < emeb> then ship length bytes to spi

2019-01-27T20:37:11 < zyp> well, the thing is, the host drivers can break up your serial writes into as many usb transfers as it likes
2019-01-27T20:37:24 < emeb> that's OK w/ me
2019-01-27T20:37:36 < emeb> but it seems like extra crap is getting into the stream somehow.
2019-01-27T20:37:47 < zyp> sure, as long as you don't assume anything about where the packet boundaries would be
2019-01-27T20:38:02 < zyp> as for extra crap, idk about that
2019-01-27T20:38:07 < emeb> I don't think I am - I use the incoming sizes, not assuming any fixed size
2019-01-27T20:38:14 < zyp> maybe LF/CRLF translation happening?
2019-01-27T20:38:26 < emeb> but I send eg 71338 bytes and receive 71344
2019-01-27T20:38:34 < emeb> 16 extra
2019-01-27T20:39:02 < emeb> hmm... will look for CR/LF.
2019-01-27T20:39:03 < qyx> 6 you mean
2019-01-27T20:39:10 < emeb> yes
2019-01-27T20:39:55 < zyp> to figure out where the extra bytes come from, start by figuring out what and where the extra bytes are :)
2019-01-27T20:40:07 < emeb> so simple!

2019-01-27T20:40:34 < zyp> as in, log the data you put in and log the data that comes out, and compare it
2019-01-27T20:40:53 < emeb> yes
2019-01-27T20:40:54 < zyp> hmm
2019-01-27T20:41:06 < emeb> logging output is tricky w/ big data and tiny RAM.
2019-01-27T20:41:12 < zyp> I guess it could also be xon/xoff flow control if that's somehow enabled
2019-01-27T20:41:31 < zyp> how about doing loopback?
2019-01-27T20:42:02 < zyp> or even hex-loopback so that the translation doesn't happen in reverse on the return channel
2019-01-27T20:42:20 < zyp> i.e. translate every received byte into ascii hex and send it back
2019-01-27T20:42:24 < emeb> I've been using my digi scope to capture output. Works for start & end of packet where CS edge is nearby. Not so great in the middle.
2019-01-27T20:42:53 < zyp> you might want to get a cheap usb logic analyzer if you don't have one already
2019-01-27T20:43:11 < emeb> I've got one. Just haven't gotten it out yet.
2019-01-27T20:43:50 < emeb> just wanted to find out if there was something dumb I didn't know about re USB inserting crap.
2019-01-27T20:44:37 < zyp> there's nothing like that in ACM itself, it should be a transparent pipe
2019-01-27T20:44:48 < emeb> good - that's what I was assuming.
2019-01-27T20:45:09 < zyp> so it must be either the host doing something weird or a bug somewhere that corrupts something
2019-01-27T20:45:27 < emeb> yeah. will keep banging on it. thx for ideas.

2019-01-27T21:18:27 < zyp> maybe you just need to open the serial port in binary mode on the host
2019-01-27T21:18:40 < emeb> perhaps.
2019-01-27T21:19:00 < emeb> I'm using "open()" and "write()" calls, not fopen/fwrite.
2019-01-27T21:19:17 < emeb> open/write don't seem to support binary mode flags?
2019-01-27T21:22:40 < zyp> maybe you need to do something like stty -F /dev/ttyACM0 -onlcr -onlret
2019-01-27T21:23:32 < Rajko> emeb, O_BINARY ?
2019-01-27T21:25:10 < emeb> Rajko: no such flag for open()
2019-01-27T21:28:12 < fenugrec> emeb, +1 what zyp said about XON/XOFF
2019-01-27T21:28:41 < fenugrec> there's a truckload of O_* flags to disable all the medieval termios crap too
2019-01-27T21:29:14 < emeb> fenugrec: using fopen/fwrite w/ "wb" seems to be helping.
2019-01-27T21:30:15 < emeb> but the termios stuff seems like a good lead to chase down.
2019-01-27T21:30:30 < fenugrec> emeb, if you can, use sigrok's libserialport
2019-01-27T21:30:30 < emeb> any pointers on where in the docs to find those details?

2019-01-27T21:39:36 < zyp> at some point you should just drop ACM entirely and use libusb instead
2019-01-27T21:39:58 < zyp> IMO libusb is easier to deal with than serial ports
2019-01-27T21:40:21 < emeb> zyp: yeah - starting to seem like going down a rathole
2019-01-27T21:40:36 < emeb> these are the lessons we learn when trying to take shortcuts.
2019-01-27T21:40:39 < fenugrec> zyp, I'd like to think so too, but ACM gives you cross-platform without doing a driver circus act on win*
2019-01-27T21:41:41 < zyp> depends
2019-01-27T21:42:33 < zyp> if windows compatibility is desired, HID is probably easier
2019-01-27T21:43:03 < zyp> after all, windows doesn't autobind the usb serial driver to devices it doesn't know about, so you'll have to make .inf files
2019-01-27T21:43:13 < fenugrec> can it ever not be a pain to juggle libusb / usbX / usbK / winusb / usb-win32
2019-01-27T21:43:23 < fenugrec> true, HID is definitely an option
2019-01-27T21:43:28 < zyp> and at that point, you might as well make it bind to winusb instead
2019-01-27T21:43:48 < zyp> I've done plenty of usb on windows too, I find it fairly painless
2019-01-27T21:44:32 < zyp> IIRC half the stuff you listed were obsolete even before I started playing with usb on windows years ago
2019-01-27T21:45:26 < fenugrec> ok, TBH I was discouraged early on by those forks of forks half-working, so my experience is limited to simple garbage that is well served by ACM
2019-01-27T21:45:29 < zyp> if you're doing plain usb on windows, in 99% of cases you want the device bound to winusb, and normal modern libusb would then be able to find and open it just as easy as on other platforms
2019-01-27T21:46:16 < zyp> oh, and starting with win8, you can also do some descriptor magic to make windows bind winusb by default, but I haven't tried doing that myself yet
2019-01-27T21:47:23 < fenugrec> good to know

2019-01-27T23:00:24 < Rajko> zyp, isnt CDC a way to bind the usb serial driver
2019-01-27T23:00:49 < bitmask> steffy
2019-01-27T23:00:52 < bitmask> you see the new panel?
2019-01-27T23:00:54 < Rajko> also, whenever i do anything as a serial port, windows LOVES to attach the Microsoft Intellimouse driver to it and not let me use the COM port normally unless i delet sermouse from starting
2019-01-27T23:01:40 < bitmask> about to make another but this silver glue takes forever to dry
2019-01-27T23:02:32 < zyp> Rajko, CDC is a usb class with a bunch of subclasses, ACM is the serial subclass of it
2019-01-27T23:03:06 < Rajko> neither prolific, cp2102 nor ft232h use CDC ACM tho, always need custom driver
2019-01-27T23:03:15 < Rajko> is there something wrong with ACM
2019-01-27T23:03:52 < zyp> a device declaring itself as a CDC ACM device will be autodetected as a serial device on linux and macos, but not on windows
2019-01-27T23:03:55 < tjq> Steffanx: thankyou
2019-01-27T23:04:17 < tjq> I've been filling the ovens
2019-01-27T23:04:21 < zyp> on windows they need an .inf file to instruct windows to bind the usb serial driver
2019-01-27T23:05:04 < zyp> I assume the reason usb serial bridge chips are not using ACM is because they want to simplify the protocol
2019-01-27T23:05:13 < zyp> ACM requires an interrupt endpoint for out of band signalling
2019-01-27T23:05:21 < zyp> and it has to be there even if you don't need it

2019-01-27T23:40:10 < Steffanx> I like snow. just to witness how crazy dutchland goes. We had like 3-4cm last week and dutchland went all crazy.

2019-01-27T23:57:06 < BrainDamage> what amuses me is that highways here get snow plowed, but in switzerland not
2019-01-27T23:57:16 < zyp> wat
2019-01-27T23:57:29 < BrainDamage> cross the border and you start playing a roller coaster
2019-01-27T23:57:51 < zyp> if it's drivable at all, they can't be getting much snow :p
2019-01-27T23:58:35 < BrainDamage> 20-30 cm is drivable, but still shit to drive in
2019-01-27T23:59:04 < BrainDamage> esp on the highway with the trucks, they tend to dig holes
2019-01-27T23:59:15 < BrainDamage> so you play a roller coaster of bumps

2019-01-28T00:02:19 < BrainDamage> i guess it's not necessary since it's flat
2019-01-28T00:03:21 < zyp> my old car was taller under and not flat, it could do deep snow better

2019-01-28T00:46:16 < englishbot> [Grimstad, Norway] [*Sunday Night*]: Windy. Snow this evening will give way to snow showers overnight. Low -4C. Winds NNE at 30 to 50 km/h. Chance of snow 90%. 3-7cm of snow expected. Winds could occasionally gust over 65 km/h. [*Monday*]: Snow showers before noon. Becoming partly cloudy later. High -2C. Winds N at 25 to 40 km/h. Chance of snow 40%.
2019-01-28T00:46:53 < catphish> bitmask: i believe the parallel cells aren't relevant to the process
2019-01-28T00:47:46 < bitmask> I guess I would need to get balance charge boards and charge through their, I had planned on using a separate charger with balance charge function but that complicates things
2019-01-28T00:47:58 < bitmask> there*
2019-01-28T00:48:30 < catphish> there are various ways to balance cells anyway, but generally one just buys a management board from china and let it do its thing
2019-01-28T00:59:42 -!- catphish [~catphish@unaffiliated/catphish] has quit [Quit: Leaving]
2019-01-28T01:16:16 < zyp> yeah, number of cells in parallel doesn't matter
2019-01-28T01:17:27 < bitmask> what if they are different capacity cells though
2019-01-28T01:17:35 < zyp> a chain of three cells in series are equivalent to a chain of three groups in series, each group consisting of multiple cells in parallel as far as balancing is concerned
2019-01-28T01:17:38 < bitmask> it shouldnt matter right?
2019-01-28T01:18:01 < zyp> no, but that sounds dumb
2019-01-28T01:18:06 < bitmask> ok
2019-01-28T01:18:36 < zyp> cells in parallel will per definition always be at the same voltage
2019-01-28T01:18:47 < bitmask> yea I know
2019-01-28T01:18:59 < bitmask> I get it
2019-01-28T01:19:03 < zyp> and since voltage is coupled to state of charge, that means they will be balanced
2019-01-28T01:21:00 < zyp> two cells will have twice the capacity of one cell, so connecting three cells in parallel will be equivalent to connecting two cells in parallel with one cell :p
2019-01-28T01:21:16 < zyp> so different capacities in itself won't be a problem
2019-01-28T01:22:06 < zyp> but the differences in chemistries that causes the different capacities might give a different I/V/SoC relationship, which is indesireable
2019-01-28T01:26:29 < zyp> karlp, I'm getting closer to revisiting the plan of getting some more energy metering in here, I wanna know where my money is going, and I wonder how to best do it
2019-01-28T01:26:37 < zyp> panel looks like this: https://bin.jvnv.net/file/vUXFc.jpg
2019-01-28T01:27:03 < karlp> Thorn: I liked the totten mechanismums thanks
2019-01-28T01:27:20 < zyp> so your 12-module bars should be a good fit, but I don't need to measure the neutrals
2019-01-28T01:27:56 < zyp> but since your CTs attach together, will it be rigid enough if I skip every other CT?
2019-01-28T01:28:36 < englishman> ooh indicators on breakers
2019-01-28T01:28:50 < zyp> yeah, those indicate residual current
2019-01-28T01:29:10 < englishman> every circuit is RCD protected?
2019-01-28T01:29:24 < englishman> regulation?
2019-01-28T01:29:37 < zyp> you can push the test button and it will give you some pulse sequence that tells you the residual current in mA
2019-01-28T01:30:09 < zyp> and the green apparently will turn yellow and then red as it nears the 30 mA tripping point
2019-01-28T01:30:22 < karlp> zyp: yeah, you can skip as many cts as  you like really.
2019-01-28T01:30:32 < karlp> I've got gaps in mine at home too.
2019-01-28T01:31:05 < karlp> re the cdc-acm discussion earlier, cdc-acm doesn't offer aas much control over the eextra signals and pins as thhe chip vendors wanted, so they mostly all use their own driver
2019-01-28T01:31:25 < zyp> they'll still stay properly connected to the bar even when not being attached to any neighbors?
2019-01-28T01:31:34 < karlp> yeah, no problem
2019-01-28T01:31:37 < zyp> cool
2019-01-28T01:32:24 < karlp> you can just bars, use your own modbus/rtu, get current, or put in bars+gate+mains and get mqtt/http/snmp/modbus-tcp and have powerfactor too.
2019-01-28T01:32:33 < karlp> mix and match at your leisure.
2019-01-28T01:32:46 < zyp> yeah, I remember that from last we talked
2019-01-28T01:33:53 < zyp> I figure I'd start with just the bars to get current, and extend that later to get proper energy metering
2019-01-28T01:34:14 < karlp> yeah, no problem.
2019-01-28T01:34:31 < karlp> modbus rtu is easy, and realyl, current is all most people _actually_ need
2019-01-28T01:34:45 < karlp> they just all got told that they had to have an _energy_ meter
2019-01-28T01:34:59 < zyp> and I still need to see when I can fit it into the budget :)
2019-01-28T01:35:01 < karlp> which is true for billing, not really nearly as relevant for operational monitoring stuff.
2019-01-28T01:35:44 < karlp> I'm working on getting the price of the gate+mains down, new gen stuff, but bars won't change an awful lot short term
2019-01-28T01:38:31 < zyp> well, they are reasonably priced already
2019-01-28T01:39:04 < karlp> the bars are, IMO, yeah.  cheaper is always better.
2019-01-28T01:39:17 < zyp> I would have ordered them right away if not for the fact that I have a ton of other stuff I would also like to order right away :)
2019-01-28T01:39:20 < karlp> but I'd like to get the other stuff down, won't happen on current gen thoughh.
2019-01-28T01:41:59 < zyp> would be nice if the gateway soft could run on an rpi, I could power the entire thing from PoE then
2019-01-28T01:44:13 < zyp> I also figured out some neat uses for the current sensors
2019-01-28T01:45:31 < zyp> I expect that monitoring the current draw of the laundry machine could identify fairly easily what sort of program it's running
2019-01-28T01:45:58 < zyp> i.e. distinguish between only washing and wash+dry
2019-01-28T01:46:34 < zyp> and in the former case, be used to trigger a reminder that there's clean laundry in the machine that needs to be hung to dry

2019-01-28T03:37:04 < rue_shop1> anyone who can help me with an openocd thing?
2019-01-28T03:41:53 < rue_shop1> hahhaa
2019-01-28T03:42:15 < rue_shop1> "7 sings your not in a good state to be coding"
2019-01-28T03:42:18 < rue_shop1> if (flag)  j = 1;   
2019-01-28T03:42:18 < rue_shop1> flag = 0;
2019-01-28T03:42:31 < rue_shop1> "for some reason, flag is always 0!"
2019-01-28T03:42:49 < Cracki> wat
2019-01-28T03:42:59 < Cracki> looks like journalist code
2019-01-28T03:44:44 < rue_shop1> maybe today I should just stick to cleaning the shop?
2019-01-28T03:45:32 < rue_shop1> ouch my head
2019-01-28T03:46:43 < rue_shop1> no I got an error here and I'm not in a state I can see it
2019-01-28T03:48:53 < Cracki> error is "flag = 0"
2019-01-28T03:48:59 < Cracki> obviously
2019-01-28T03:49:05 < Cracki> or did you mean openocd
2019-01-28T03:49:27 < rue_shop1> hard to tell, I'm trying to play while migrane
2019-01-28T03:49:37 < rue_shop1> I have an openocd issue
2019-01-28T03:50:01 < specing> rue_shop1: that would not compile in Ada, as Ada conditionals are strictly structured  if .. then .. else .. end if;
2019-01-28T03:50:02 < rue_shop1> the sequence I have for flasing the stm32 hangs when it tries to do an autoerase
2019-01-28T03:50:57 < rue_shop1> can anyone take a look at the openocd command for programming and see if they can spot an obvious error?
2019-01-28T03:51:38 < Cracki> why do you ask if you aren't even showing it
2019-01-28T03:51:41 < rue_shop1> https://paste.debian.net/1062812/
2019-01-28T03:51:47 < rue_shop1> :) I'm asking to ask :)
2019-01-28T03:54:04 < Cracki> explain to us how you arrived at this sequence of commands
2019-01-28T03:54:37 < rue_shop1> I think specing helped me make it
2019-01-28T03:54:40 < rue_shop1> https://paste.debian.net/1062813/
2019-01-28T03:54:43 < rue_shop1> here is more detail
2019-01-28T03:55:01 < rue_shop1> I think it needs something else before the -c flash command
2019-01-28T03:55:25 < specing> rue_shop1: grep openocd ~/.bash_history
2019-01-28T03:55:32 < Cracki> http://openocd.org/doc/html/General-Commands.html
2019-01-28T03:55:45 < rue_shop1> specing, its run from a makefile
2019-01-28T03:55:53 < specing> darn
2019-01-28T03:55:53 < Cracki> WARNING: target/stm32f1x_stlink.cfg is deprecated, please switch to target/stm32f1x.cfg
2019-01-28T03:56:05 < Cracki> the first thing you should fix, or know why you want it that way
2019-01-28T03:56:10 < rue_shop1> Cracki, knowning the commands is one think, knowing what sequence to program an stm32 is another thing
2019-01-28T03:56:39 < rue_shop1> Cracki, is anyone using openocd to flash stm32s?
2019-01-28T03:56:50 < Cracki> sure
2019-01-28T03:56:52 < rue_shop1> or are they just clicking a button in an IDE?
2019-01-28T03:56:56 < Cracki> yes, that :P
2019-01-28T03:57:01 < rue_shop1> :/
2019-01-28T03:57:09 < Cracki> and that can be openocd, or segger stuff, or a blackmagic probe
2019-01-28T03:57:23 < rue_shop1> so there is 1 person in the world who wrote the ide that knows how to use openocd to flash an stm32
2019-01-28T03:57:41 < Cracki> defeatist thinking
2019-01-28T03:57:53 < rue_shop1> given the history, yes
2019-01-28T03:58:44 < Cracki> again: WARNING: target/stm32f1x_stlink.cfg is deprecated, please switch to target/stm32f1x.cfg
2019-01-28T03:58:53 < Cracki> read it, understand it, try it
2019-01-28T03:59:21 < Cracki> or explain why you ignore it
2019-01-28T03:59:34 < rue_shop1> because I'm pretty sure its not part of the problem
2019-01-28T03:59:45 < Cracki> have you tried it?
2019-01-28T03:59:49 < rue_shop1> I'll do it, then we can move on
2019-01-28T04:00:16 < Cracki> also take a look in those files you specify. there might be interesting stuff in there
2019-01-28T04:01:11 < rue_shop1> ok, it still locks up every 2nd time its run
2019-01-28T04:01:34 < Cracki> good. what's the target, what runs on it
2019-01-28T04:01:45 < rue_shop1> stm32
2019-01-28T04:01:53 < rue_shop1> stm32f103c6t8
2019-01-28T04:01:53 < Cracki> what meaning... is there anything that messes with debug access
2019-01-28T04:02:03 < specing> the classic stm
2019-01-28T04:02:20 < rue_shop1> nothing messing with it that I know of
2019-01-28T04:02:46 < rue_shop1> this looks a lot to me like the flash command is hitting the stm32 when its not in a state its ready to be flashed in
2019-01-28T04:02:56 < rue_shop1> and I have no idea what kinda states there are
2019-01-28T04:03:52 < rue_shop1> I'm kinda thinking this has been done a lot, esp by people in this channel, and someone can say "hey, thats not the right command sequence to flash it! *this* is!..."
2019-01-28T04:04:08 < rue_shop1> aka there shouldn't have to be any "figuring out" going on
2019-01-28T04:04:26 < rue_shop1> just a lookup of the defacto standard answer
2019-01-28T04:04:30 < Cracki> I agree, someone probably did this already, but I'm not the right one for that

2019-01-28T04:08:07 < Cracki> note how that dude uses while true; do... so be careful with his advice

2019-01-28T04:15:29 < Ultrasauce> did you take karlp's advice yet
2019-01-28T04:15:48 < rue_shop1> ah it does init, reset, flash
2019-01-28T04:16:11 < Cracki> "reset halt" specifically
2019-01-28T04:17:43 < rue_shop1> thats it!
2019-01-28T04:17:52 < rue_shop1> :) thankyou
2019-01-28T04:18:42 < rue_shop1> I think
2019-01-28T04:19:06 < rue_shop1> yea, ok, the rest are my coding problems
2019-01-28T04:19:28 < rue_shop1> I think in the state I'm in, I would hit problems at 3 trying to count my fingers
2019-01-28T04:19:38 < Cracki> what was it?
2019-01-28T04:19:59 < rue_shop1> openocd -f $(OPENOCD_SCRIPTS_DIR)/interface/stlink-v2.cfg -f $(OPENOCD_SCRIPTS_DIR)/target/stm32f1x.cfg -c init -c "reset halt" -c "flash write_image erase ./$(BINARY).elf" -c "verify_image ./$(BINARY).elf" -c "reset run" -c shutdown
2019-01-28T04:20:37 < Cracki> so "reset halt" did it?
2019-01-28T04:20:57 < Cracki> oh well
2019-01-28T04:21:14 < rue_shop1> yup
2019-01-28T04:26:40 < rue_shop1> haha 72Mhz is fast
2019-01-28T04:28:54 < rue_shop1> huh, I can see a light flash when its only on for 0.4ms
2019-01-28T04:29:10 < Cracki> your eyes perceive logarithmically
2019-01-28T04:29:48 < Cracki> 0.4ms of a second is "only" -30 dB or something
2019-01-28T04:30:52 < rue_shop1> coool
2019-01-28T04:30:56 < Cracki> if full-on blinds you, that should be a firefly
2019-01-28T04:31:13 < Cracki> glad you got it working
2019-01-28T04:31:50 < rue_shop1> np @ 0.2ms
2019-01-28T04:32:02 < rue_shop1> its a 0.2ms pulse every second too
2019-01-28T04:32:31 < rue_shop1> Cracki, fixing that makes life SO much happier, turn around time and all
2019-01-28T04:32:42 < rue_shop1> nothing like waiting for your programmer to time out every second time you run it
2019-01-28T04:32:52 < Cracki> heh
2019-01-28T04:33:02 < Cracki> I'm sure there's a value to configure timeout :P
2019-01-28T04:33:24 < rue_shop1> I'd like to save the bandaids for other peoples problems
2019-01-28T04:34:20 < rue_shop1> 0.1ms and I can still see it
2019-01-28T04:34:45 < rue_shop1> this is pretty good considering that its flashing it via a 74hc595
2019-01-28T04:34:46 < Cracki> then it's either very faint, or those 0.1ms might not be 0.1ms really
2019-01-28T04:34:56 < rue_shop1> its on the scope
2019-01-28T04:35:04 < Cracki> good, you got the right tools
2019-01-28T04:35:16 < rue_shop1> I'm gonna check the 595 transfer time, I'm curious how narrow I can go
2019-01-28T04:35:35 < Cracki> I would have said duty cycle function on a multimeter, but those might only be 0.1% precise (not talking about accurate)
2019-01-28T04:35:50 < Cracki> 0.1ms is nothing. it should do at least 10 times better
2019-01-28T04:36:20 < Cracki> oh hm, depends on spi too...
2019-01-28T04:36:24 < rue_shop1> yea
2019-01-28T04:36:26 < johntramp> I am using an external gpio interrupt to read accelerometer data. In the ISR I disable the IRQ, clear the IRQ, read the data, and then enable the IRQ. However quite often the interrut has somehow been set during the time it was disabled (and the ISR immediately reenters when it shouldn't).  Is there something I am missing here?
2019-01-28T04:36:30 < rue_shop1> just hooking up the logic ana
2019-01-28T04:37:00 < Cracki> johntramp, don't disable it, but clear the flag at the end of the ISR
2019-01-28T04:37:30 < Cracki> scope/LA on the interrupt line, let your ISR wiggle some other output to see when it's active
2019-01-28T04:37:49 < johntramp>  that is what I am doing re scope, and toggling of LEDs when in the ISR
2019-01-28T04:38:05 < Cracki> clearing the flag right away of course would leave you open to it getting set while you're in the ISR
2019-01-28T04:38:21 < Cracki> anyway... it's an accelerometer
2019-01-28T04:38:40 < Cracki> how long does your handler take? longer than one period between interrupts _should_ take?
2019-01-28T04:39:06 < Cracki> put differently: if that ISR is called again right away, is there new data already?
2019-01-28T04:40:08 < Cracki> rue_shop1, random 595 datasheet says fclock max ~21-36 MHz for 4.5-5.0 volt
2019-01-28T04:40:51 < Cracki> 5 mhz for 2 volts, so that's a lower bound for 3.3

2019-01-28T04:44:40 < rue_shop1> hahah wholy *&%^&^$ it takes 7us to do the transfer
2019-01-28T04:44:57 < johntramp> it has an internal fifo, and running it at 6.5khz I need it to fill the fifo to a certain level before reading it, else there is too much overhead and the fifo overflows
2019-01-28T04:46:39 < rue_shop1> so I'm clocking in at 1.2Mhz
2019-01-28T04:46:59 < rue_shop1> gpio_set_mode(GPIOC, GPIO_MODE_OUTPUT_2_MHZ,  GPIO_CNF_OUTPUT_PUSHPULL, GPIO13);
2019-01-28T04:47:05 < rue_shop1> that kinda makes sense
2019-01-28T04:47:50  * rue_shop1 dials it to 10Mhz
2019-01-28T04:49:17 < rue_shop1> odd, same, and there is only 1 NOP
2019-01-28T04:51:22 < rue_shop1> ok, modulating 32 solinoids with this wont be an issue
2019-01-28T04:52:49 < Cracki> johntramp, so... when is the interrupt triggered
2019-01-28T04:53:14 < Cracki> maybe it's triggering multiple times because you haven't cleared the fifo enough yet
2019-01-28T04:53:44 < Cracki> just speculating... give a part number and data sheet maybe
2019-01-28T05:29:46 < Ultrasauce> use the spi peripheral to drive it and you'll be able to go >20MHz trivially

2019-01-28T05:54:08 < johntramp> Cracki: I am just reading the INT pin state on the start of the ISR, and clearing the interrupt and exiting immediately if the interrupt is not supposed to be triggered - not a pretty solution but it seems to be working fine
2019-01-28T05:54:29 < Cracki> so... help me out here, explain it
2019-01-28T05:54:46 < Cracki> are you implying INT isn't asserted but the handler is STILL triggered a second time?
2019-01-28T05:54:51 < johntramp> yes
2019-01-28T05:54:59 < Cracki> good. that's something we can work with.
2019-01-28T05:55:21 < Cracki> clearing the interrupt does eventually work, or does it keep running the handler?
2019-01-28T05:56:20 < johntramp> so the interrupt is disabled, I clear the interrupt, read the data, and the INT line goes low. then, by the time I get to the end of the ISR, the interrupt has been set again even though it has been disabled
2019-01-28T05:56:33 < Cracki> you'll also want to clear that interrupt several cycles before ending the handler. iirc cortex-m interrupt handler execution would otherwise not notice and schedule another run
2019-01-28T05:56:54 < Cracki> you need to clear the interrupt AFTER the int line goes low
2019-01-28T05:57:06 < johntramp> even though it is disabled?
2019-01-28T05:57:10 < Cracki> disabling the interrupt only disables executing the handler, it does not disable setting the interrupt flag
2019-01-28T05:57:16 < johntramp> ahhh
2019-01-28T05:57:32 < Cracki> :) I think that's solved now :P
2019-01-28T05:58:24 < Cracki> (but please confirm anyway)
2019-01-28T05:59:14 < Cracki> how did you hook up that interrupt line to your stm32? exti I assume?
2019-01-28T06:01:17 < johntramp> I am actually using an silicon labs EFR32 part (cortex m4)
2019-01-28T06:01:18 < Cracki> if you dig in the reference manual, EXTI_PR (pending register) is probably the term you wanna start with
2019-01-28T06:01:22 < Cracki> ic ic
2019-01-28T06:01:43 < johntramp> but fairly similar to stm32f4 from my experiences
2019-01-28T06:02:06 < johntramp> except has a bluetooth module alongside 
2019-01-28T06:02:07 < Cracki> they'll hook that up to the nvic somehow as well
2019-01-28T06:02:12 < Cracki> interesting
2019-01-28T06:03:55 < johntramp> yes that seems to have fixed the issue for me :)   clearing the interrupt after reading out the FIFO data, which is when the INT line would deassert
2019-01-28T06:03:56 < Cracki> they call it "exti"-something too
2019-01-28T06:05:58 < johntramp> I am using the silabs HAL library, it deals with the EXTI* registers
2019-01-28T06:06:25 < johntramp> thanks for your help :)

2019-01-28T09:39:45 < kakimir> interesting
2019-01-28T09:40:31 < kakimir> what FB?
2019-01-28T09:40:43 < kakimir> any circuit you could show me?

2019-01-28T09:41:42 < Haohmaru> football?
2019-01-28T09:41:46 < kakimir> why LDO instead of opamp?
2019-01-28T09:42:03 < Haohmaru> ldo can give loads of current
2019-01-28T09:42:07 < Haohmaru> opamps usually can't
2019-01-28T09:42:21 < qyx> because you don't want to do the regulation in software
2019-01-28T09:42:22 < Haohmaru> just guessing
2019-01-28T09:42:29 < qyx> TI slva861 for example
2019-01-28T09:42:56 < qyx> but idk, pbp + opamp may be doable
2019-01-28T09:43:02 < qyx> I would never try that
2019-01-28T09:43:19 < qyx> because vregs are cheap and confirmed working
2019-01-28T09:43:25 < kakimir> yes
2019-01-28T09:43:37 < Haohmaru> but where's teh innovation in that

2019-01-28T09:43:56 < qyx> or here ^
2019-01-28T09:44:07 < qyx> you could also use PWM output instead of dac
2019-01-28T09:44:10 < qyx> I did that too
2019-01-28T09:44:52 < kakimir> irrelevant
2019-01-28T09:46:37 < kakimir> oh.. and transistor driver needs to be sinking type
2019-01-28T09:47:12 < kakimir> that doesn't work that well with some LDO or does it?
2019-01-28T09:48:48 < kakimir> load will be PNP type
2019-01-28T09:50:20 < qyx> wait what
2019-01-28T09:50:27 < qyx> you want to do a load?
2019-01-28T09:50:47 < kakimir> yes

2019-01-28T09:51:18 < kakimir> yes
2019-01-28T09:51:21 < kakimir> I noticed
2019-01-28T09:51:22 < qyx> I though you wanted to do a DAC controlled CV vreg using a PNP pass transistor

2019-01-28T15:37:43 < qyx> ahy hints how to get a freertos bt of a given thread? (gdb)
2019-01-28T15:41:14 < PaulFertser> qyx: are you using openocd and thread awareness enabled?
2019-01-28T15:41:46 < PaulFertser> qyx: if yes, then you can see the list of threads with "i thr" and switch to the thread you're interested in with "thr N" (N is the thread number) and then bt.
2019-01-28T15:42:19 < qyx> no thread awareness
2019-01-28T15:42:24 < qyx> I am not aware of such thing
2019-01-28T15:43:32 < PaulFertser> qyx: you can add "$_TARGET configure -rtos auto" to the end of your config or invocation line to enable it.
2019-01-28T15:43:54 < PaulFertser> qyx: but with a recent enough freertos version you'll have to add one file to your project, see the OpenOCD manual.
2019-01-28T16:03:55 < karlp> (free rtos thread detection is ~busted since free rtos 8.2 https://github.com/karlp/oocd-rtos-locm3/tree/master/fr-blink
2019-01-28T16:04:23 < karlp> only downside to sticking with freertos 8.2 is you don't get some of the newer "stream buffers" stuff
2019-01-28T16:05:46 < karlp> I've not spent anytime trying to fix it.  10.0.x was broken in freertos side, (they broke a bunch of os aware debuggers) but that only fixes the detection portion.
2019-01-28T16:12:04 < aandrew> Thorn: I've only done RLE, sorry
2019-01-28T16:13:17 < aandrew> qyx: thanks for the tip, looking at heatshrink
2019-01-28T16:13:37  * karlp added compression.txt if anyone wants to chime in with more right now.
2019-01-28T16:14:01 < aandrew> qyx: thread apply all bt
2019-01-28T16:14:21 < aandrew> qyx: have you added that little blurb to put the freertos thread info into the binary?
2019-01-28T16:14:42 < karlp> aandrew: what version of freertos are you using?
2019-01-28T16:14:55 < aandrew> karlp: whatever is in cubemx, it's not new
2019-01-28T16:15:22 < Haohmaru> when an LDO goes out of input voltage (power goes own) - does it sorta "shrug" and leave the output power rail unaffected, or can it sorta start acting weird and eat away the power rail (assuming there are caps there keeping some charge) ?
2019-01-28T16:16:10 < karlp> depends on the LDO, but all sorts of things can happen
2019-01-28T16:16:28 < aandrew> const int __attribute__((used)) uxTopUsedPriority = configMAX_PRIORITIES;
2019-01-28T16:17:05 < aandrew> that with openocd's configure -rtos auto seems to work well for me
2019-01-28T16:21:59 < karlp> hrmm, brand new cube install will use freertos 9.0, which would n't work with openocd for me.
2019-01-28T16:23:12 < Haohmaru> is there something simple i can do to give a few hundred milliseconds of guaranteed "power", the stuff i could think of is slapping a series diode and then a big reservoir cap..
2019-01-28T16:23:27 < Haohmaru> but this introduces a diode voltage drop of course
2019-01-28T16:25:49 < karlp> huh, "nice" cube is gneerating freertos with the cmsis-rtos wrappers

2019-01-28T16:28:51 < karlp> you can also put the caps on the input side of your ldo....
2019-01-28T16:29:34 < Haohmaru> true, but there they will power more things
2019-01-28T16:30:20 < Haohmaru> while i was tring to just give the "brainz" slightly longer time to live so they can detect the power outtage and emit a message
2019-01-28T16:30:36 < BrainDamage> a schottcky diode drop can be as low as 200mV
2019-01-28T16:31:09 < BrainDamage> compensate with larger cap and you can have your brownout detection
2019-01-28T16:32:00 < BrainDamage> alternatively, use a P-mos
2019-01-28T16:32:15 < BrainDamage> and tie the gate to gnd
2019-01-28T16:32:36 < Haohmaru> power-mosfet or p-channel mosfet?
2019-01-28T16:32:43 < BrainDamage> pchannel mosfet
2019-01-28T16:32:52 < Haohmaru> okay, i can slap that in falstad
2019-01-28T16:33:27 < Haohmaru> the mosfet can act as a switch, high-Z or "connected" without a voltage drop, right?
2019-01-28T16:35:15 < BrainDamage> it has a voltage drop due to the internal resistance, but it's lower than a diode
2019-01-28T16:35:23 < BrainDamage> however, thinking more, the mos won't work
2019-01-28T16:35:59 < Haohmaru> it changed the discharge response..
2019-01-28T16:36:01 < BrainDamage> since they are sufficiently symmetrical that if the input is 0 and the output is powered by the cap, you'll get a channel on the source side and it'll conduct backwards
2019-01-28T16:36:05 < BrainDamage> discharging it
2019-01-28T16:36:12 < Haohmaru> i'm not very gud with transistors and FETs :/
2019-01-28T16:37:48 < BrainDamage> a simple solution could be to give a sep ldo for the mcu, and put diode and cap before ldo
2019-01-28T16:38:01 < BrainDamage> provided you have sufficient voltage margin
2019-01-28T16:38:14 < Haohmaru> hm, true
2019-01-28T16:38:44 < Haohmaru> 5V (from a switching regulator), then i use LM1117 for 3.3V
2019-01-28T16:38:55 < Haohmaru> so, a schottky there?
2019-01-28T16:39:05 < BrainDamage> yup, can even use a regular diode
2019-01-28T16:39:12 < Haohmaru> and a big cap between that and the 3.3V reg
2019-01-28T16:39:41 < Haohmaru> regular like.. rectifying diode?
2019-01-28T16:39:58 < BrainDamage> regular, as in, whatever you can get your hands on
2019-01-28T16:40:16 < Haohmaru> k
2019-01-28T16:40:37 < BrainDamage> 5V-Vdiode-Vldo-3.3V is the deltaV that the cap will discharge
2019-01-28T16:41:11 < BrainDamage> how much do you want for it to stay up? and what's the current consumption?
2019-01-28T16:43:03 < Haohmaru> that's a little hard to say right now.. but i know i'll have to figure out the value of the reservoir cap later
2019-01-28T16:45:12 < karlp> I prototyped using the AWD on the raw vin to detect the brownout early, and turn off periphs. worked ok.
2019-01-28T16:46:13 < Haohmaru> i'm measuring the input power (12V) as early (in the circuit) as possible, that is.. before a series diode

2019-01-28T18:59:22 < kakimir> and it should have low power consumption
2019-01-28T19:00:31 < kakimir> all them can be on and off at same time
2019-01-28T19:00:53 < kakimir> so basically one input -> 13fets in different potentials
2019-01-28T19:03:04 < kakimir> is there any cheap gate driver that could handle this potential difference thing

2019-01-28T19:08:33 < aandrew> although I wonder if the filter could be designed so that instead of PCB between the two sides you actually routed a slot
2019-01-28T19:08:35 < kakimir> the distance required is multiplied with like 4x
2019-01-28T19:11:27 < kakimir> all the corners are potential sparking points

2019-01-28T19:46:29 < zyp> maybe you don't need more than 1.2mm if the goal is to isolate N from PE when they are supposed to be at the same level anyway
2019-01-28T19:46:49 < karlp> I'd never heard of galvanically isolated wifi ports anyway
2019-01-28T19:47:03 < zyp> that's not what the article said either
2019-01-28T19:47:09 < karlp> and in a power meter thing like that product is, I would have thought you'd put isolation elsewhere in the system
2019-01-28T19:47:15 < zyp> it said they had digital isolators on the signals below it before
2019-01-28T19:47:28 < zyp> but they removed it to save on BOM and remove some EMI problems

2019-01-29T00:38:20 < englishman> >esp1488
2019-01-29T00:38:26 < englishman> you know its good
2019-01-29T00:43:07 < zyp> hah
2019-01-29T00:44:10 < zyp> what for? charger or general monitoring?
2019-01-29T00:44:58 < englishman> whole house
2019-01-29T00:45:16 < englishman> both the car and evse already log charging, i dont think i need another one
2019-01-29T00:46:11 < zyp> so general monitoring
2019-01-29T00:46:25 < englishman> yeah
2019-01-29T00:46:27 < zyp> how much is it?
2019-01-29T00:46:42 < englishman> 125gbp plus taps
2019-01-29T00:46:57 < englishman> plus vat
2019-01-29T00:47:01 < zyp> huh, that's expensive
2019-01-29T00:47:52 < englishman> a bit yeah
2019-01-29T00:47:59 < zyp> might as well just get karlp's stuff at that point

2019-01-29T00:48:46 < englishman> modular?
2019-01-29T00:50:37 < englishman> wow its UL certed
2019-01-29T00:51:17 < zyp> https://bin.jvnv.net/file/vUXFc.jpg <- this kind

2019-01-29T00:53:19 < zyp> there's some variations, apparently in .is they don't switch N, so each single phase circuit is only a single module breaker
2019-01-29T00:54:06 < zyp> I'm planning to get a pair of those 12-sensor bars, but only mount the ones that would go on L
2019-01-29T00:54:10 < PeterM> kakimir depending on the speed you need the mosfets to switch, (say, if its only 10s of hz) you can use photodiode output optocouplers - they will generate say 10v at 10-100ua
2019-01-29T00:54:45 < PeterM> should be plenty to act as load switches

2019-01-29T01:07:14 < jadew> so here's a question, do you need a ground connection for RCD breakers?
2019-01-29T01:07:42 < jadew> I have a box full of them and I wonder if I can just replace the old ones (it's an old building and I don't think I have a ground connection at the panel)
2019-01-29T01:08:08 < jadew> I guess I could check one out

2019-01-29T01:11:54 < qyx> you always have some kind of PE, which may cause some leakage current to flow from/to L or N
2019-01-29T01:12:10 < jadew> what's PE?
2019-01-29T01:12:17 < Lux> in old houses you only have 2 wires
2019-01-29T01:12:24 < Lux> PE is ground
2019-01-29T01:12:30 < Lux> or earth
2019-01-29T01:12:47 < qyx> in order to make RCD nonfunctional you would have to have an IT system
2019-01-29T01:12:49 < jadew> then I don't understand what qyx means
2019-01-29T01:12:57 < qyx> oe. the PE completely isolated
2019-01-29T01:12:58 < Lux> for a RCD to work you definetly need 3 wires
2019-01-29T01:13:19 < jadew> why does it need the earth connection?
2019-01-29T01:13:34 < Lux> cause in those old installations earth and N are just shorted in the plug
2019-01-29T01:13:55 < Lux> at least from what i've seen so far
2019-01-29T01:13:58 < jadew> ah, I don't think that's the case here
2019-01-29T01:14:10 < qyx> yeah thats TN-C
2019-01-29T01:14:55 < qyx> the RCD would not be able to detect leakage between L and PEN
2019-01-29T01:15:14 < jadew> we have an earth connection for some of the power outlets
2019-01-29T01:15:25 < aandrew> balls.
2019-01-29T01:15:54 < jadew> qyx, I thought it detects that the current is different between L and N
2019-01-29T01:15:55 < aandrew> I connected two FPGA IO banks to 3.3V but they're for LVDS and should have been at 2.5V
2019-01-29T01:16:05 < qyx> however it would work with leakage between L and PEN *before* the RCD
2019-01-29T01:16:12 < aandrew> I am hoping that since it is a receiver-only design that it might still work alright for these prototypes
2019-01-29T01:16:28 < qyx> ie. if you touch L and plumbing or heayers or whatever
2019-01-29T01:16:45 < qyx> jadew: it does
2019-01-29T01:17:16 < jadew> qyx, so why is the earth connection important?
2019-01-29T01:17:20 < englishman> here N is never switched i think it's against code
2019-01-29T01:17:32 < Lux> pretty sure that would just cause random tripping of the rcd
2019-01-29T01:17:49 < Lux> it's too easy to get leakage in those systems
2019-01-29T01:18:19 < qyx> jadew: because if you only have 2 wires, you cannot have different currents in them
2019-01-29T01:18:27 < Lux> i even had a lan cable trip the rcd once
2019-01-29T01:18:36 < qyx> you have to leak some current from L or N
2019-01-29T01:18:52 < qyx> through the ground for example
2019-01-29T01:19:12 < jadew> qyx, uhmm... isn't current normally going through both L and N? like
2019-01-29T01:19:16 < jadew> L => Load => N
2019-01-29T01:19:28 < qyx> yes, thats the point
2019-01-29T01:19:30 < jadew> the only leak here that I'm concerned about is L => earth
2019-01-29T01:19:42 < jadew> why would L => N matter and how would it be detected?
2019-01-29T01:19:45 < englishman> thats what an rcd is for no?
2019-01-29T01:20:31 < qyx> yes but if you make your ground from N *after* the RCD, it cannot be detected
2019-01-29T01:20:37 < englishman> oh i see your question
2019-01-29T01:20:53 < qyx> necause your L-ground leak will go through the N
2019-01-29T01:21:09 < jadew> qyx, ah, I see what you mean, yeah... I'm not planning to do that
2019-01-29T01:21:27 < qyx> thats what Lux is saying
2019-01-29T01:21:30 < catphish> jadew: he said leak FROM L OR N (to earth)
2019-01-29T01:21:35 < englishman> if you have grounds randomly added after the breaker panel, wtf
2019-01-29T01:21:50 < qyx> englishman: thats TN-C
2019-01-29T01:22:00 < qyx> you only have L and PEN
2019-01-29T01:22:14 < qyx> PEN is split in individual sockets
2019-01-29T01:22:18 < jadew> qyx, and there's a way to counterract TN-C leaks too?
2019-01-29T01:22:33 < jadew> how would it know the difference between a leak and a load?
2019-01-29T01:22:36 < zyp> uh
2019-01-29T01:22:39 < englishman> according to wikipedia, you still dont add grounds wherever, there is one ground back at the source
2019-01-29T01:22:44 < zyp> wtf are you guys talking about?
2019-01-29T01:22:53 < zyp> RCDs are not connected to PE at all
2019-01-29T01:22:56 < englishman> ^
2019-01-29T01:23:01 < qyx> they are not
2019-01-29T01:23:09 < catphish> it doesn't matter where the current leaks from, as long as it doesn't return through the rcd it's detectable
2019-01-29T01:23:28 < zyp> RCDs have a sum transformer, i.e. a CT that measures the sum through all the conductors on the circuit
2019-01-29T01:23:32 < qyx> yeah thats the gheneralization of the whole problem
2019-01-29T01:23:36 < catphish> if it leaks into the actual physical soil below you, it's detected as missing return current
2019-01-29T01:23:47 < jadew> that was my impression as well
2019-01-29T01:23:51 < zyp> that is correct
2019-01-29T01:24:12 < catphish> so your incoming L and N (which connect only to load) have their currents compared, simple as that
2019-01-29T01:24:16 < jadew> so I should be able to replace the old breakers with RCDs without having an earth connection at the panel?
2019-01-29T01:24:22 < zyp> correct
2019-01-29T01:24:37 < jadew> that's what I wanted to know
2019-01-29T01:24:41 < jadew> thanks
2019-01-29T01:24:44 < catphish> as long as you don't create a ground *after* the RCD, all current leaked is detectable
2019-01-29T01:24:49 < qyx> wat, no
2019-01-29T01:24:53 < jadew> obviously...

2019-01-29T01:25:01 < catphish> jadew: yes you can
2019-01-29T01:25:09 < qyx> you ncannot break PEN in a TN-C
2019-01-29T01:25:13 < jadew> but is there a way to even detect that scenario?
2019-01-29T01:25:14 < catphish> as long as there's no earth created *after* the panel (inside)
2019-01-29T01:25:29 < qyx> how are you going to connect it?
2019-01-29T01:25:47 < catphish> you have a ground from somewhere, right?
2019-01-29T01:25:55 < zyp> is TN-C actually used for anything but the main supply anywhere?
2019-01-29T01:26:05 < catphish> and that ground is eventually connected to N outside the property if not at the panel
2019-01-29T01:26:10 < qyx> yes in old installations
2019-01-29T01:26:15 < qyx> as jadew mentiomed
2019-01-29T01:26:15 < zyp> all TN systems I've seen are TN-C-S
2019-01-29T01:26:38 < jadew> this terminology is new to me
2019-01-29T01:26:43 < jadew> PEN = earth wire
2019-01-29T01:26:50 < zyp> where it's TN-C from the grid and into the house, where PEN gets split into PE and N
2019-01-29T01:26:51 < jadew> TN-C = N connected to PEN?
2019-01-29T01:26:52 < qyx> you cannot simply replace 1-pole breaker with a 2-pole one or a RCD
2019-01-29T01:27:03 < zyp> jadew, C = combined PE and N
2019-01-29T01:27:17 < zyp> S = separate PE and N
2019-01-29T01:27:20 < jadew> got it
2019-01-29T01:27:22 < qyx> here in .sk TN-C is very common
2019-01-29T01:27:24 < Lux> zyp in installations older than 30 years or so
2019-01-29T01:27:29 < zyp> fair
2019-01-29T01:27:35 < zyp> most old stuff here is IT
2019-01-29T01:27:37 < qyx> TN-C-S is mandatory from 2000 or so
2019-01-29T01:27:37 < catphish> but the choice of any of those systems makes no difference to RCD operation
2019-01-29T01:27:44 < Lux> i've got it here in a few non renovated sections in the house
2019-01-29T01:27:59 < zyp> catphish, correct
2019-01-29T01:28:17 < catphish> you still put an RCD on your L/N input after earth is sparated
2019-01-29T01:28:31 < catphish> so it compares current into the legitimate load with current out of it
2019-01-29T01:28:31 < Lux> looks like that: https://preview.ibb.co/me3zAJ/20180617_124518.jpg

2019-01-29T01:29:13 < englishman> safer than a live PE
2019-01-29T01:29:17 < catphish> is that a bypassed rcd running on one pole?
2019-01-29T01:29:32 < qyx> no
2019-01-29T01:29:38 < qyx> it is a tn-c socket
2019-01-29T01:29:39 < catphish> what is it?
2019-01-29T01:29:41 < Lux> that's from an era where no rcd existed
2019-01-29T01:29:43 < zyp> haha
2019-01-29T01:29:48 < zyp> cute
2019-01-29T01:29:55 < qyx> Lux: where are you from?
2019-01-29T01:29:56 < jadew> that looks dangerous
2019-01-29T01:30:08 < catphish> so black is live?
2019-01-29T01:30:12 < catphish> and the other 2 are N and E?
2019-01-29T01:30:15 < Lux> right
2019-01-29T01:30:17 < catphish> oh ok
2019-01-29T01:30:20 < zyp> yes, blue is always N
2019-01-29T01:30:31 < qyx> ntw PEN should be green-yellow, not blue
2019-01-29T01:30:42 < qyx> but otherwise yes, common here
2019-01-29T01:30:49 < Lux> it'd be more dangerous without the bridge
2019-01-29T01:30:49 < catphish> in UK we have 2 colouring systems, in one of them black is neutral
2019-01-29T01:31:02 < catphish> (old system luckily)
2019-01-29T01:31:23 < jadew> Lux, don't know... I've always considered N to be live too
2019-01-29T01:31:24 < zyp> UK electric stuff is all sorts of fucked up though :p
2019-01-29T01:31:32 < zyp> ring circuits and whatnot
2019-01-29T01:31:36 < catphish> i've never seem earth split at a socket like that
2019-01-29T01:31:40 < jadew> and with that arrangement you're basically connecting the chasis to a live wire
2019-01-29T01:31:48 < qyx> ues
2019-01-29T01:32:08 < qyx> if your PEN breaks, you gen L on your metal device
2019-01-29T01:32:23 < qyx> fuk android
2019-01-29T01:32:34 < catphish> zyp: i have no idea why ring circuits are still used
2019-01-29T01:33:03 < catphish> has the benefit of more total current with less wire though
2019-01-29T01:33:16 < PeterM> im still trying to see the issue with putting an RCD on that - it is no LESS safe than without an RCD
2019-01-29T01:33:16 < qyx> Lux: wjats your TN-C land if I may ask?
2019-01-29T01:33:53 < qyx> PeterM: it would break your ground if it trips
2019-01-29T01:34:11 < catphish> PeterM: one obvious problem with putting an rcd on that is that it will detect leaks from the chassis of the appliance and trip when it shouldn't
2019-01-29T01:34:28 < PeterM> catphish that isnt a safety issue though
2019-01-29T01:34:33 < catphish> breaking ground doesn't seem unsafe if there's no live
2019-01-29T01:34:43 < PeterM> qyx you can get single pole rcds tyo only break L
2019-01-29T01:34:47 < catphish> not ideal, but not unsafe
2019-01-29T01:35:04 < Lux> qyx: austria, a house built 1900
2019-01-29T01:35:18 < qyx> yeah, neighbor
2019-01-29T01:35:19 < englishman> like switzerland, only nicer
2019-01-29T01:35:20 < catphish> one benefit of uk, afaik we've *always* had proper earth wiring
2019-01-29T01:35:26 < englishman> like germany, only cheaper
2019-01-29T01:35:40 < Lux> nah germany is cheaper than here
2019-01-29T01:35:53 < englishman> swap switzerland and germany then
2019-01-29T01:36:50 < Lux> but it really depends on the area
2019-01-29T01:37:09 < catphish> would be easier if germany just took over the whole lot
2019-01-29T01:37:11 < Lux> tirol is pretty expensive housing wise, but munich too
2019-01-29T01:38:21 < englishman> so apparently, when stock broking companies take your stock purchase order, they dont have to actually buy the stock
2019-01-29T01:38:29 < englishman> instead, they just keep your money
2019-01-29T01:38:47 < englishman> since most people lose money on the stock market, this is a profitable enterprise
2019-01-29T01:39:31 < jadew> so they're gambling against you
2019-01-29T01:39:34 < Lux> i guess anything with handling other peoples investments is profitable
2019-01-29T01:40:09 < jadew> I wanted to buy some stock too, but it seems it's not easy to buy US stock from europe
2019-01-29T01:40:29 < Lux> hmm how do most people lose money on the stock market if it's only been growing ?
2019-01-29T01:40:45 < jadew> it's not only been growing tho
2019-01-29T01:40:58 < Lux> iirc the longest you have to wait after a crash was 8 years till regaining your capital
2019-01-29T01:41:12 < jadew> it seems there's a bubble - bubble-popping cycle
2019-01-29T01:41:19 < Lux> if you've spread your stocks that is

2019-01-29T07:30:10 < Cracki> planar data just makes you use n-fold more cache lines
2019-01-29T07:30:39 < Cracki> planar is a good idea these days

2019-01-29T07:32:46 < Cracki> it's just three lines instead of one

2019-01-29T07:33:45 < Cracki> not necessarily in that order
2019-01-29T07:34:02 < Cracki> how come you have planar data anyway

2019-01-29T07:34:47 < Cracki> converting wouldn't "trash" the cache". it would involve three lines for reading and one for gathering into
2019-01-29T07:35:34 < upgrdman_> it's my TelemetryViewer thinggy. "y" values are stored in sequence. "x" can be timestamps, which i dont want to duplicate for every dataset, so i want to store it in a seaparate array

2019-01-29T07:36:22 < Cracki> you'd do well not to update the x/t values
2019-01-29T07:36:37 < Cracki> unless that's for the monkey head
2019-01-29T07:37:00 < upgrdman_> but the time needs to be accurate if the user wants time as the domain
2019-01-29T07:37:16 < upgrdman_> and e.g. apple says to interleave if you give a shit about performance  https://developer.apple.com/library/archive/documentation/3DDrawing/Conceptual/OpenGLES_ProgrammingGuide/TechniquesforWorkingwithVertexData/TechniquesforWorkingwithVertexData.html
2019-01-29T07:37:25 < Cracki> ah so your x values are time, not "screen coordinates"

2019-01-29T08:06:16 < jpa-> Cracki: planar vs. interleaved doesn't matter much if the vertex data is read sequentially, but if it is random access and not all is accessed then that "just three cache lines instead of one" becomes 3x slower
2019-01-29T08:06:50 < jpa-> i guess for upgrdman's case he'll be rendering most or all of the vertices; but if it was some game with a huge scene only part of which is visible, it would make a difference
2019-01-29T08:12:13 < upgrdman> oh ya that makes sense
2019-01-29T08:12:57 < upgrdman> hmm well maybe not. vertex shaders can execute in "random" order... it's not like they cleanly march through each vertex in order
2019-01-29T08:13:02 < jpa-> if it all is going to be read into cache anyway (and fits there), it's true that it shouldn't matter whether it is planar or interleaved
2019-01-29T08:13:09 < upgrdman> but i suppose the gpu silicon manages that order to be cache-friendly-ish

2019-01-29T09:57:15 < PeterM> for mains?

2019-01-29T09:57:44 < kakimir> problem with optocouplers is power consumption
2019-01-29T09:58:08 < qyx> maybe a series cap + diode + parallel cap to ground?
2019-01-29T09:58:13 < PeterM> there is a part ht0440 that is sorta expensive but is ok for power consumption

2019-01-29T10:04:41 < qyx> with optoisolation or any other digital isolation you need additional power to pull the gate up/down
2019-01-29T10:04:54 < qyx> if you AC couple the gate (transformer, cap) you don't need it

2019-01-29T19:50:53 < antto> 100% success
2019-01-29T19:51:03 < zyp> I wrote a flash config storage thing at work today
2019-01-29T19:51:19 < antto> C++?
2019-01-29T19:51:24 < zyp> no, C
2019-01-29T19:51:28 < antto> aww
2019-01-29T19:51:53 < zyp> I've been debating for a while how to go about it
2019-01-29T19:52:25 < zyp> I've got two 16k pages to use
2019-01-29T19:52:46 < antto> bluh, that's a big page
2019-01-29T19:53:06 < zyp> yeah
2019-01-29T19:53:23 < zyp> there's four of them in total, but I wanna use the other two for other stuff
2019-01-29T19:54:35 < zyp> the simple way of storing config in flash is to just make a big struct, and then alternate pages every time I need to write it
2019-01-29T19:54:55 < emeb> karlp: no, that was a stand-alone project since I hate using FTDI chips for USB->SPI bridging.
2019-01-29T19:55:20 < zyp> but that has some drawbacks, you get tied to a layout and you need to have ram enough to hold a copy of the entire thing too
2019-01-29T19:55:46 < qyx> nanopb to the rescue
2019-01-29T19:55:47 < kakimir> alternate pages?
2019-01-29T19:56:09 < qyx> yes, because you do not want to erase the current page if there is no copy of it
2019-01-29T19:56:11 < zyp> yeah, you want to always keep one page intact
2019-01-29T19:56:20 < emeb> Rickta59: I've got a whole lot of different things that I use the FPGA for - I've got some SDR stuff, an FM audio synthesizer, etc.
2019-01-29T19:56:34 < zyp> if you erase and rewrite the same page, you risk bricking the device if the process gets interrupted
2019-01-29T19:56:52 < kakimir> my device will just return to uncalibrated state
2019-01-29T19:57:22 < kakimir> requiring user to calibrate it in order to return the functionality
2019-01-29T19:57:31 < zyp> I'm storing stuff like bus addrs, which the whole system relies on to be able to communicate
2019-01-29T19:57:32 < kakimir> restore
2019-01-29T19:57:42 < kakimir> okay
2019-01-29T19:57:51 < qyx> zyp: internal flash?
2019-01-29T19:57:59 < zyp> yeah, this is TI RM4x
2019-01-29T19:58:29 < zyp> it has one bank for code that can't be rewritten while executing from it and one bank for data
2019-01-29T19:58:34 < zyp> the latter got four 16k pages
2019-01-29T19:59:00 < kakimir> thing with xmc1100 is that 64k flash
2019-01-29T19:59:02 < kakimir> also
2019-01-29T19:59:11 < zyp> I decided to go for a sort of key/value store
2019-01-29T19:59:17 < kakimir> totally new balance of ram and flash
2019-01-29T19:59:38 < zyp> each page has a header with a sequence number and then an array of records
2019-01-29T19:59:50 < zyp> every time I need to write a new value, I just append to the array
2019-01-29T20:00:06 < kakimir> how big is your conf?
2019-01-29T20:00:10 < zyp> when doing lookups, I search from the end so I find the newest value for a key
2019-01-29T20:00:35 < Ecco> let's talk flux
2019-01-29T20:00:37 < emeb> zyp: a buddy of mine uses program flash on STM32F0 for eeprom emulation - he's got a little struct with all his stuff in it and just adds more & more to the flash page sequentially until the page is full, then only erases it once and starts over at the beginning.
2019-01-29T20:00:52 < emeb> when reading he scans thru until he finds the last one and uses that.
2019-01-29T20:00:58 < zyp> yeah, that's similar to what I'm doing
2019-01-29T20:01:06 < qyx> zyp: I did this once but I don't remember what for
2019-01-29T20:01:09 < qyx> https://github.com/iqyx/kvstore
2019-01-29T20:01:11 < zyp> except I'm doing it per value
2019-01-29T20:01:11 < qyx> I have never used it
2019-01-29T20:01:23 < emeb> primitive wear leveling since you don't erase often.
2019-01-29T20:01:42 < Ecco> Let's talk soldering flux. Currently I have two kind of flux: a very liquid one (kinda like water). Works great, but will evaporate as soon as I put the iron nearby. Smells terrible when evaporating, but doesn't leave any residue.
2019-01-29T20:02:01 < zyp> my idea is when one page is full, I'll defragment it by copying the latest values for all the keys over to the other page
2019-01-29T20:02:11 < zyp> but I haven't written the defragmenting yet
2019-01-29T20:02:14 < Ecco> Then I got another one, comes in a syringe. Works even better, doesn't evaporate when soldering, and doesn't smell. Very very useful to use. But leaves a terribly sticky residue on the board.
2019-01-29T20:02:51 < zyp> the flash has ECC per 64 bits, so I made my records 64-bit
2019-01-29T20:03:11 < qyx> Ecco: I am using the latter one and wash the PCB in IPA after soldering
2019-01-29T20:03:12 < zyp> 16-bit key, 16-bit reserved, 32-bit for value
2019-01-29T20:03:22 < qyx> are you hashing your keys?
2019-01-29T20:03:29 < qyx> or you have value->id table?
2019-01-29T20:03:39 < zyp> in what sense?
2019-01-29T20:03:58 < zyp> I'm just doing a linear search for the lookup
2019-01-29T20:03:58 < Ecco> IPA = Isopropyl Alcohol?
2019-01-29T20:03:59 < qyx> 16bit key is small to contain "reasonable_string"
2019-01-29T20:04:15 < qyx> Ecco: yes
2019-01-29T20:04:16 < zyp> ah, all my parameters will have assigned keys
2019-01-29T20:04:21 < zyp> I'll make some enums of that
2019-01-29T20:04:25 < emeb> zyp: ah so you have a tag/value pair and you can update them fine-grained.
2019-01-29T20:04:30 < zyp> yeah
2019-01-29T20:04:42 < Ecco> qyx: interesting. Two questions then: would regular ethanol work as well? How exactly do you wash out the goo?
2019-01-29T20:04:47 < emeb> so when you scan thru you just update all the latest tag/value pairs
2019-01-29T20:05:16 < emeb> seems like defragging would just be a normal pass thru and then write all pairs at once to new page.
2019-01-29T20:05:30 < zyp> I'm not loading entire config at once
2019-01-29T20:05:41 < emeb> ah
2019-01-29T20:05:47 < emeb> search for just one 
2019-01-29T20:05:59 < zyp> I only want to load the config at startup anyway, so each module looks up their own values
2019-01-29T20:06:07 < zyp> and deals with missing values as they see fit

2019-01-29T20:06:59 < zyp> e.g. when I make an ip stack, it'll do something like config_get_u32(CONFIG_IP_ADDRESS, &address);
2019-01-29T20:07:13 < zyp> where CONFIG_IP_ADDRESS comes from some enum
2019-01-29T20:08:37 < emeb> yep
2019-01-29T20:09:25 < emeb> so defragger has to search for every possible tag.
2019-01-29T20:09:26 < Ecco> https://hackaday.com/2011/06/07/cleaning-flux-from-pcbs-the-easy-way/
2019-01-29T20:09:39 < Ecco> "We used to throw assembled boards into one of several off the shelf dishwashers and ran them through a regular wash cycle"
2019-01-29T20:09:42 < Ecco> lolwut?
2019-01-29T20:09:42 < zyp> yeah, defragging will be O(log(n)) I figure
2019-01-29T20:09:59 < emeb> giant hash table or something.
2019-01-29T20:10:30 < emeb> are the values fixed or variable depending on the tag?
2019-01-29T20:10:35 < emeb> (in size)
2019-01-29T20:11:17 < zyp> I figure I'll just loop backwards through every record in the old page, then search new page for the same tag and if not found copy record and append to new page
2019-01-29T20:11:34 < zyp> all records are the same size, so they can be copied easily
2019-01-29T20:11:45 < zyp> but I figure some will be float and some will be u32
2019-01-29T20:11:55 < zyp> and possibly other types
2019-01-29T20:11:56 < emeb> that simplifies it
2019-01-29T20:12:16 < zyp> if larger values are needed, I'll split it across multiple parameters
2019-01-29T20:13:16 < zyp> one benefit of doing it like that is that I have two kinds of nodes
2019-01-29T20:13:35 < zyp> they run different firmwares, but it's built from the same base, so e.g. the networking code is shared
2019-01-29T20:13:50 < qyx> Ecco: ultrasonic cleaner with 1/1 water-IPA or curaprox with IPA
2019-01-29T20:14:39 < zyp> and since doing it like this is flexible, I can now have some tags that only exists on one kind and some that only exists on the other, and some that exists on both
2019-01-29T20:15:12 < zyp> this is running on freertos, so in practice it means they have some tasks in common and some tasks of their own
2019-01-29T20:15:41 < emeb> nice
2019-01-29T20:15:47 < emeb> you like freertos?
2019-01-29T20:15:58 < qyx> I am not zyp but I do
2019-01-29T20:16:06 < zyp> it's not bad
2019-01-29T20:16:16 < emeb> it seems to be quite popular
2019-01-29T20:16:46 < zyp> thing is, I might eventually have to deal with SIL certification and shit, and freertos seems to have a fairly simple migration path to safertos if it comes to that
2019-01-29T20:17:06 < Ecco> I always assumed water would competely destroy a PCB

2019-01-29T20:19:33 < zyp> possibly the worst part of moving is in the end when you're more or less done and tired of dealing with moving, and then you have to go back and clean up the place so it looks nice
2019-01-29T20:19:41 < emeb> yeah
2019-01-29T20:19:49 < emeb> PITA, but it's good to get the deposit back
2019-01-29T20:19:58 < zyp> yeah
2019-01-29T20:20:01 < Ecco> and how about ultrasonic cleansing? Couldn't that damage the PCB?
2019-01-29T20:20:22 < Ecco> Just to give you guys an idea, currently I do plain old ethanol + toothbrush
2019-01-29T20:20:36 < Ecco> works meh
2019-01-29T20:20:44 < emeb> nothing wrong with that.
2019-01-29T20:20:54 < emeb> just don't use the GF's toothbrush
2019-01-29T20:20:54 < zyp> when I moved in 2015 I didn't have to deal with that, place was water damaged and the interior would be torn down to be renovated as soon as I was out :p
2019-01-29T20:21:09 < Ecco> yeah, so far I haven't destroyed any PCB, but the toothbrush tastes funny afterwards
2019-01-29T20:22:00 < emeb> mmm - pine rosin
2019-01-29T20:22:12 < emeb> tastes like Greek retsina!
2019-01-29T20:22:26 < Ecco> :-D
2019-01-29T20:23:01 < Ecco> I could buy an ultrasonic cleansing machine

2019-01-29T20:23:15 < Steffanx> What happens if you dont clean it zyp? Theyll have you pay them doing it?
2019-01-29T20:23:46 < Steffanx> Reviews werent too great last time i checked
2019-01-29T20:23:50 < emeb> ultrasonic machines usually use water w/ weak soap
2019-01-29T20:23:53 < Steffanx> @ thorn
2019-01-29T20:24:41 < Ecco> what if i put ethanol in there?
2019-01-29T20:25:11 < emeb> summons dread Cthulu. don't do it. ;)
2019-01-29T20:25:21 < emeb> (should be fine)
2019-01-29T20:25:33 < BrainDamage> just don't put it near a flame
2019-01-29T20:25:53 < Ecco> I definitely can buy DI water though

2019-01-29T20:52:29 < kakimir> 24V
2019-01-29T20:52:42 < kakimir> I mean 19V is bearable
2019-01-29T20:52:51 < kakimir> 12V is total crap
2019-01-29T20:53:06 < Steffanx> Sounds like a random laptop charger
2019-01-29T20:53:10 < Ecco> Yeah ok
2019-01-29T20:53:12 < kakimir> I bought converter for dell laptop charger
2019-01-29T20:53:19 < Ecco> Would it be better than a Hakko 888D though?
2019-01-29T20:53:24 < kakimir> to 5.5mm / 2.5mm plug
2019-01-29T20:54:00 < kakimir> Ecco: definitelly
2019-01-29T20:54:14 < Ecco> Interesting. How?
2019-01-29T20:54:15 < kakimir> you just need to improvise with accessory parts

2019-01-29T21:04:55 < kakimir> but $50 nah
2019-01-29T21:05:30 < kakimir> good magnifying glass with multi joint arm and mains powered led lights is $50
2019-01-29T21:07:23 < kakimir> I have one but it's still pain to use
2019-01-29T21:07:32 < kakimir> I rather just use my lazer gaze

2019-01-29T23:36:08 < karlp> zyp: yeah, log based storage seems like the "right" way of using big pages if your structs to store are much smaller.
2019-01-29T23:36:14  * karlp just hugs l1 with eeprom...
2019-01-29T23:36:58 < karlp> we did an rolling index thing for eeprom emulation in flash as well, for some things that needed to be written more often.
2019-01-29T23:37:12 < zyp> I haven't really thought much about the page size, I mainly went that way for the flexibility
2019-01-29T23:39:43 < Steffanx> Partial write (due to power down or whatever) are just discarded in your case i assume zyp?

2019-01-29T23:40:11 < zyp> worst case they would have invalid CRC I guess
2019-01-29T23:40:32 < Steffanx> Oh you do crc?
2019-01-29T23:40:40 < zyp> but I would expect line writes to be atomic
2019-01-29T23:40:56 < zyp> flash is 144-bit wide
2019-01-29T23:41:01 < zyp> i.e. 128 bit plus crc
2019-01-29T23:41:15 < zyp> but crc for each 64-bit half is independent
2019-01-29T23:41:33 < zyp> so I made my records 64-bit

2019-01-29T23:44:49 < karlp> we wrote the index counter last, after the data, and that's atomic word, 
2019-01-29T23:44:55 < karlp> so it doesn't count as valid until then..

2019-01-30T00:37:21 < zyp> oh, by the way, regarding freertos
2019-01-30T00:37:41 < zyp> what would be the nicest way to do inter-task RPC?

2019-01-30T00:39:20 < zyp> say I have a service that can be used by other tasks (like the config thing), but all calls have to go through the service task since MPU only lets the service touch some underlying memory
2019-01-30T00:42:56 < zyp> I guess the service should have some sort of queue that the caller pushes a command object to, and the object should probably also contain some information about how to report back completion
2019-01-30T00:43:08 < Getty> I am not sure for your specifics, but MessagePack makes a very good package for MPU communication, low memory usage even on big data
2019-01-30T00:43:26 < zyp> messagepack?
2019-01-30T00:43:28 < Getty> like literally the lowest possible required memory ;-) no package is more effective beside if you design your own
2019-01-30T00:44:16 < Getty> yeah check it up, really sexy shit, i use it for everything on my 64K 107
2019-01-30T00:44:36 < zyp> I'm not really looking for serialization
2019-01-30T00:44:50 < Getty> well it helps making such a thing, so i am not sure what you ask for
2019-01-30T00:44:51 < mitrax> doesn't FreeRTOs have some queues mechanism? xQueueSend() and the like
2019-01-30T00:45:05 < zyp> yeah
2019-01-30T00:45:31 < zyp> probably a queue for commands and an event group for reporting back completion

2019-01-30T00:46:09 < zyp> or maybe even a queue for reporting back, not sure which is lighter
2019-01-30T00:46:11 < mitrax> have the service thread read from a queue, it's blocking when it's empty, then pass around some pointers to the RPC argument and if the call needs to be marshalled wait on a semaphore or something on the calling thread until the message is retrieved and processed
2019-01-30T00:46:17 < englishman> https://i.imgur.com/RQE4paF.gifv
2019-01-30T00:46:38 < mitrax> never messed with freertos but i guess it has all the synchronization primitives to do that
2019-01-30T00:46:55 < zyp> sure, it's just a matter of how to combine them most sensibly
2019-01-30T00:48:02 < mitrax> i'm getting really shitty read speed from a NOR flash, around (0.8MBytes/sec) using SPI at 45Mhz (flash is rated at 6.5MBytes at 50Mhz), it's in polling mode (ST's hal) but even without DMA it shouldn't be that slow should it?
2019-01-30T00:50:25 < zyp> where's the bottleneck?
2019-01-30T00:51:58 < mitrax> i haven't investigated yet, but i only saw a x2 speed increase when going from a /16 prescaler to /2
2019-01-30T00:57:33 < bitmask> arduinos have built in eeprom? how did I not know this?

2019-01-30T01:09:38 < mitrax> zyp: seems to be within the HAL_SPI_Receive() function cause that's all my calling when benchmarking, the transfer loop is pretty straightforward, on RXNE flag read DR, increment dst pointer, there's a timeout check when RXNE is not set, cpu is running at 180Mhz, the interrupt load is pretty low, maybe that's to be expected with polling SPI but 0.8 MBytes/sec that seems pretty slow

2019-01-30T03:36:03 < jadew> SSD Spare Blocks: 0
2019-01-30T03:36:09 < jadew> this means it's fucked, right?
2019-01-30T03:38:01 < mawk> not really
2019-01-30T03:38:14 < mawk> it just means that blocks will start to die and you'll lose capacity
2019-01-30T03:38:20 < mawk> but that ssd is still very good for reading a bunch of files
2019-01-30T03:38:33 < jadew> well, I have 20 Gb free and if I create a new file, it disappears after reboot
2019-01-30T03:38:36 < mawk> don't put caches or swap on it and it's fine
2019-01-30T03:38:38 < mawk> ah
2019-01-30T03:38:43 < mawk> that's a bigger issue
2019-01-30T03:39:02 < jadew> I hope it's still in warranty
2019-01-30T03:39:37 < jadew> so I shouldn't worry about losing everything on it, right?
2019-01-30T03:40:27 < mawk> I don't think so no, just from that statistic
2019-01-30T03:40:43 < mawk> but having no spare blocks left shouldn't prevent writing to it
2019-01-30T03:40:52 < mawk> it just means that once in a while a block will go bad and won't be replaced
2019-01-30T03:41:10 < jadew> I see
2019-01-30T03:41:24 < jadew> well, it's causing lots of crashes (obviously)
2019-01-30T03:41:45 < mawk> it should more or less be transparent to the computer, maybe your disk has bigger problems

2019-01-30T03:59:11 < mawk> how much sales do you expect
2019-01-30T03:59:17 < aandrew> exactly
2019-01-30T03:59:24 < branjb> anywhere from 0 to 20,000+
2019-01-30T03:59:28 < branjb> customer thinks 20,000
2019-01-30T03:59:34 < mawk> you don't have previous data from other products .
2019-01-30T03:59:35 < mawk> ?

2019-01-30T03:59:56 < branjb> it's like a 12 hour job lol

2019-01-30T05:37:07 < dongs> but im sorry for the dude that does
2019-01-30T05:37:21 < dongs> and instead of integrating shit into like eclipse build system or soemthign
2019-01-30T05:37:29 < dongs> you press build it pops up some lunixy makefile-output window

2019-01-30T05:37:39 < mawk> makefile is nice
2019-01-30T05:37:50 < mawk> you can modify it without passing an eclipse Ph.D first
2019-01-30T05:37:52 < dongs> ya well not when it takes 30 seconds

2019-01-30T05:40:26 < mawk> he had too much money on his hands
2019-01-30T05:40:48 < mawk> but I must say it's the first thing I programmed on, maybe without TI I wouldn't be a dev today
2019-01-30T05:48:47 < Cracki> we had ti 83 in high school. that got a bunch of my classmates into (casual) programming... usually because they got some random script from someone, got curious how it works, and saw it's easy

2019-01-30T14:36:16 < Laurenceb> no effect on employment
2019-01-30T14:36:46 < rmaw> well nothings actually happend yet
2019-01-30T14:37:15 < Laurenceb> yeah but there was supposed to be a depression already
2019-01-30T14:37:23 < rmaw> its make differences
2019-01-30T14:37:46 < Laurenceb> citation required
2019-01-30T14:38:39 < jpa-> but how do you know how well you'd be doing without brexit?
2019-01-30T14:38:46 < rmaw> https://snag.gy/hQzAuy.jpg
2019-01-30T14:38:53 < rmaw> 2 months after brexit
2019-01-30T14:38:58 < rmaw> brexit pizza 
2019-01-30T14:39:05 < rmaw> sainsburys made it oval
2019-01-30T14:39:07 < rmaw> for the same money
2019-01-30T14:39:11 < Laurenceb> wut
2019-01-30T14:39:13 < rmaw> that used to be round
2019-01-30T14:39:22 < Laurenceb> muh brexit
2019-01-30T14:39:22 < rmaw> pound dropped
2019-01-30T14:39:28 < rmaw> after the vote, quite alot
2019-01-30T14:39:43 < rmaw> obvious made in poland or something, so thye had to shrink the size or up the price
2019-01-30T14:40:00 < Cracki> yeah well transient spikes
2019-01-30T14:40:05 < Cracki> did it stay down or did it rebound
2019-01-30T14:40:30 < rmaw> still way down from pre brexit
2019-01-30T14:40:32 < rmaw> vote
2019-01-30T14:40:41 < Cracki> ¯\_(ツ)_/¯
2019-01-30T14:40:52 < Cracki> preserving your nation > economy 
2019-01-30T14:40:57 < Laurenceb> looks like 10% versus euro
2019-01-30T14:41:08 < Laurenceb> change due to brexit
2019-01-30T14:41:08 < Cracki> a healthy nation will have a healthy economy somehow
2019-01-30T14:41:30 < Cracki> we have limits on capitalism for a reason: it would kill nations
2019-01-30T14:41:42 < Laurenceb> and 9% change versus dollar
2019-01-30T14:41:46 < Laurenceb> hardly huge
2019-01-30T14:42:10 < rmaw> no
2019-01-30T14:42:15 < rmaw> its more like 20%
2019-01-30T14:42:22 < rmaw> 1.13 now, it was 1.4 before the vote
2019-01-30T14:43:02 < Cracki> oh btw, I'm looking for a way to get power (gnd,12v) onto around 5-10 boards that are in a row. I was thinking there must be some kind of insulation displacement stuff where I can just push the two cables onto it. anyone know such a thing?
2019-01-30T14:43:20 < Cracki> like idc but without the male/female stuff, straight onto the pcb
2019-01-30T14:43:34 < rmaw> still think there is a fair chance it won't happen
2019-01-30T14:43:40 < Laurenceb> rmaw: no ur getting confused by the noise
2019-01-30T14:44:07 < rmaw> how am I confused?
2019-01-30T14:44:28 < rmaw> GBP/EUR was 1.4 before the vote, its not 1.15
2019-01-30T14:44:31 < rmaw> now*
2019-01-30T14:45:07 < Cracki> you're comparing values with YEARS between them
2019-01-30T14:45:24 < Cracki> you think it'd otherwise have stayed flat as a mirror?
2019-01-30T14:45:54 < Laurenceb>  1.27->1.15
2019-01-30T14:46:03 < Cracki> discerning long term effects would be debatable
2019-01-30T14:46:03 < Laurenceb> a 9.5% decrease due to brexit
2019-01-30T14:46:20 < Laurenceb> https://fullfact.org/media/uploads/UK_economic_growth_within_the_G7.png
2019-01-30T14:46:24 < Laurenceb> ^more random noise
2019-01-30T14:46:28 < rmaw> well it has been pretty flat
2019-01-30T14:46:31 < Cracki> kek what happened in 09
2019-01-30T14:46:37 < Cracki> that's some dip there
2019-01-30T14:46:41 < Laurenceb> Cracki: financial crash
2019-01-30T14:46:48 < rmaw> since it dropped
2019-01-30T14:47:09 < Cracki> it's more likely that some shekel sharks fuck the economy again, rather than brexit being to blame for anything
2019-01-30T14:47:20 < Laurenceb> so worst case ~0.5% decrease due to brexit, but its lost in the noise
2019-01-30T14:47:40 < rmaw> https://snag.gy/E9CW6M.jpg
2019-01-30T14:48:00 < rmaw> looks like a big drop, then noise for 2 years
2019-01-30T14:48:11 < rmaw> ranging at a much lower level
2019-01-30T14:48:14 < Cracki> you ignore the trend before that date
2019-01-30T14:48:15 < Laurenceb> yeah a 9.5% drop
2019-01-30T14:48:22 < Laurenceb> worst case
2019-01-30T14:48:23 < mitrax> rmaw: regarding your brexit pizza example, to me that means one thing... maybe it's time for some european countries to regrow an industry instead of importing manufactured shit from all around the world.. be it food or whatever. 
2019-01-30T14:48:27 < Cracki> looks like it's been going down since 2015
2019-01-30T14:48:38 < Cracki> what mitrax said
2019-01-30T14:48:53 < karlp> mitrax: sure, just as long as consumers accept that means that lots of their food will cost more :)
2019-01-30T14:48:55 < Cracki> whatever is most profitable will be done
2019-01-30T14:49:10 < karlp> which is what all the food retailers just said this wek.
2019-01-30T14:50:19 < jpa-> raising prices on imported food just means that people will find even cheaper imported food
2019-01-30T14:50:21 < Laurenceb> https://fullfact.org/media/uploads/bank_of_england_growth_forecasts.png
2019-01-30T14:50:23 < Laurenceb> ^oops
2019-01-30T14:50:48 < karlp> jpa-: wat? you think the incentives might not be pure? ohboi
2019-01-30T14:53:34 < rmaw> Laurenceb, gbp/eur started dropping before the vote, in anticipation
2019-01-30T14:53:40 < rmaw> you can't only attribute the drop post vote
2019-01-30T14:53:55 < Laurenceb> rmaw: doesnt look much like that from the graph
2019-01-30T14:54:04 -!- cnt [uid317556@gateway/web/irccloud.com/x-tiuafdldwpeivinh] has quit [Quit: Connection closed for inactivity]
2019-01-30T14:54:19 < rmaw> preceeding the approach to the vote, it was 1.4 arguable trending up
2019-01-30T14:54:40 < rmaw> when they announced it, started dropping
2019-01-30T14:55:02 < Cracki> that 1.4 is an exchange rate, eh? you're measuring two things at once with that
2019-01-30T14:55:11 < Laurenceb> https://www.explainxkcd.com/wiki/images/f/f6/technical_analysis.png
2019-01-30T14:55:13 < Cracki> namely pounds AND euro
2019-01-30T14:55:35 < rmaw> yes..
2019-01-30T14:55:49 < jpa-> :( msvc doesn't like my macro magic
2019-01-30T14:55:56 < Laurenceb> I wonder if there is a goatkcd of that one...
2019-01-30T14:56:27 < Cracki> "random walk" is a basic assumption in finance
2019-01-30T14:56:55 < Cracki> if the future were predictable, someone would exploit the pattern, thus destroying the pattern
2019-01-30T14:57:20 < Laurenceb> more importantly, why is my car insurance so expensive
2019-01-30T14:57:25 < Laurenceb> inb4 "cuz brexit"
2019-01-30T14:57:38 < Cracki> all the permits and loicenses cost money
2019-01-30T14:57:38 < mitrax> karlp: sure some of the food that can't be produced locally will cost more, but transforming / processing can be done locally and that would create jobs (e.g the pizza thing). And for manufactured goods I'd rather pay 40-50% more on a smartphone, computer, tv screen or whatever and live in a country that still has factories and a real economy (i.e not 90% tertiary jobs)
2019-01-30T14:57:42 < jpa-> Laurenceb: they've taken your babby shaker data and used it to predict your future
2019-01-30T14:57:53 < rmaw> besides that, I have a friend who does some kind of renewable energy brokering, I was in London last weekend and hes got two clients who are holding off
2019-01-30T14:57:54 < Laurenceb> >look at price comparison sites, cheapest £1250
2019-01-30T14:57:58 < rmaw> to see what happens with brexit
2019-01-30T14:58:06 < rmaw> one os German the other some other eu
2019-01-30T14:58:09 < Laurenceb> >ring insurance guy, get it for £235
2019-01-30T14:58:11 < rmaw> it will have an effect
2019-01-30T14:58:21 < Laurenceb> this does not inspire confidence
2019-01-30T14:58:24 < Cracki> you brits drive on the wrong side of the road all the time. of COURSE insurances are worried
2019-01-30T14:58:34 < mitrax> ahaha
2019-01-30T14:58:40 < Laurenceb> who says I cant get it for £100 or something if I ring the right person
2019-01-30T14:58:48 < Laurenceb> wtf is going on
2019-01-30T14:58:57 < Cracki> yes yo uhave to ring persons
2019-01-30T14:59:12 < Laurenceb> price comparison sites seem to be useless for insurance
2019-01-30T14:59:33 < Cracki> also... 1250 wtf that's bullshit or including all the bells and whistles for the worst possible combination of factors
2019-01-30T14:59:45 < Laurenceb> Cracki: no that was basic third party only
2019-01-30T15:00:08 < Cracki> maybe the first page were sponsored results
2019-01-30T15:00:16 < Laurenceb> broker guy goes direct and knows how to fudge the policy details to get the best deal, or at least thats how he explained it
2019-01-30T15:00:18 < Cracki> or it was per year, not month
2019-01-30T15:00:26 < Cracki> also that
2019-01-30T15:00:27 < Laurenceb> he charged my £25, pretty good deal tbh
2019-01-30T15:01:22 < Laurenceb> I have a really weird rule where I can only drive 1k miles in a month, and 8k per year, but they have no way to check lol
2019-01-30T15:02:12 < Laurenceb> guess if I crashed they could check if the dash makes sense
2019-01-30T15:02:19 < rmaw> your mot has it written down
2019-01-30T15:02:27 < Laurenceb> rmaw: only once every year
2019-01-30T15:02:30 < rmaw> so when you crash into a lampost they could check our milage
2019-01-30T15:02:33 < rmaw> your*
2019-01-30T15:02:45 < Laurenceb> yeah
2019-01-30T15:03:00 < rmaw> they wouldn't .. but they could
2019-01-30T15:03:06 < Cracki> 8k/y is ~22/day. I think that's within a lot of people's usage.
2019-01-30T15:03:22 < Laurenceb> Cracki: yeah its normal to have a per year limit
2019-01-30T15:03:30 < Laurenceb> but I have weird per month limit too
2019-01-30T15:03:44 < Cracki> no eurotrip for you
2019-01-30T15:04:36 < Cracki> sooo. any recommendations as to what insulation displacement stuff there is I could solder onto a board and then push wires onto?
2019-01-30T15:05:18 < Cracki> like this, but terminal for pcb, and I'm not particular about the tooling https://commons.wikimedia.org/wiki/File:Schneidklemme-Angelegte_Ader.jpg
2019-01-30T15:05:33 < Cracki> I'm browsing digikey, haven't hit the right category yet
2019-01-30T15:06:23 < Laurenceb> wtf now parliament is discussing muh domestic abuse
2019-01-30T15:06:34 < Laurenceb> no wonder we are gunna get hard brexit
2019-01-30T15:06:47 < Laurenceb> inb4 ban muh toxic masculinity
2019-01-30T15:07:05 < Cracki> do like buttfeed did, but for your govt: fire all the hacks
2019-01-30T15:07:11 < Cracki> not banned already?
2019-01-30T15:07:33 < Cracki> if they do, you can say you're syrian (?), forbidding you would be insensitive to your culture
2019-01-30T15:07:44 < Laurenceb> >Our main aim through this work is to prevent domestic abuse by challenging the acceptability of abuse and addressing the underlying attitudes and norms that perpetuate it
2019-01-30T15:07:46 < Laurenceb> kekking
2019-01-30T15:07:56 < Cracki> pussies
2019-01-30T15:08:48 < Laurenceb> their wordsalads are delaying actual useful discussion when we have time limit
2019-01-30T15:08:52 < Laurenceb> facepalming
2019-01-30T15:08:56 < Cracki> arresting people for wrongthink and facecrime, but not for actual crimes
2019-01-30T15:09:10 < Cracki> I think they speculate on running over the limit
2019-01-30T15:09:31 < Cracki> goal is to prevent anything from being done
2019-01-30T15:09:40 < Laurenceb> hard brexit would be a bit retarded, but so is parliament
2019-01-30T15:10:18 < Cracki> britain is a meme country already, very little to lose now
2019-01-30T15:10:34 < Cracki> (not that germany is better...)
2019-01-30T15:12:27 < Laurenceb> >enable high-risk domestic abuse offenders to be subject to polygraph testing
2019-01-30T15:12:29 < Laurenceb> oh wow
2019-01-30T15:12:30 < Cracki> ze fuk that's pretty much what I want but I found it on a german website as a "novelty" https://cdn.weka-fachmedien.de/thumbs/media_uploads/images/1383042411-16-wirthbild5.jpg.950x534.jpg
2019-01-30T15:12:44 < Cracki> high risk
2019-01-30T15:12:44 < Laurenceb> inb4 >use emdrive to fight domestic abuse
2019-01-30T15:13:06 < Cracki> so if they think you look funny, you're having an inquisition
2019-01-30T15:13:18 < Laurenceb> >use emdrive mounted on a eestor powered zano to fight domestic abuse
2019-01-30T15:13:46 < Laurenceb> >use Alex Jones to fight domestic abuse
2019-01-30T15:14:07 < Cracki> he'd actually fight it
2019-01-30T15:14:36 < Laurenceb> uk parliament are unironically considering compulsory polygraph tests
2019-01-30T15:14:37 < Cracki> how much domestic abuse is committed by women? I'd watch him fight that
2019-01-30T15:14:41 < Laurenceb> my orbital sides
2019-01-30T15:15:04 < Cracki> you people need to police your gene pool. these specimens in your govt aren't viable.
2019-01-30T15:15:12 < Laurenceb> https://www.science20.com/gerhard_adam/pseudoscience_lie_detectors-93551
2019-01-30T15:15:57 < Cracki> I'd really like to play with a polygraph... see what it can read
2019-01-30T15:18:17 < Laurenceb> *insert xkcd technical analysis cartoon here*
2019-01-30T15:22:00 < karlp> Cracki: look at te/harwin/amp et al directly, I've seen some pcb soldered blades that you were meant to just push cable into like you want, but can't remember the vendor
2019-01-30T15:22:57 < Cracki> eh fuck it, I'll use pin strips and skewer the cable on those
2019-01-30T15:24:34 < karlp> what areyou trying to avoid again?
2019-01-30T15:25:13 < Cracki> ooh those look ideal http://www.avx.com/products/connectors/wire-to-board/standard-idc-18-24-awg-00-9176/
2019-01-30T15:25:30 < karlp> yeah, those are like I was remembering
2019-01-30T15:25:50 < karlp> I think I've seen even shorter, like one pair of blades, instead of two, but very similar
2019-01-30T15:26:37 < karlp> is the distance betwen your baords going to be very variable?
2019-01-30T15:28:09 < karlp> and are you hoping to have the wire feed through and do multi tap is it?

2019-01-30T23:51:07 < bitmask> essentially, its for a .9" oled so one line at a time
2019-01-30T23:52:43 < bitmask> I want to scroll through the root items, then when you select on the new level shows on the right half of the screen, if you select another then the right half switches to the left and the new level is shown on the right, and if you select a leaf node (variable to change) then it displays the name on the left and the value being changed on the right
2019-01-30T23:53:52 < Ecco> Hi :)
2019-01-30T23:54:01 < Ecco> Do you guys use solder paste stencils?
2019-01-30T23:54:09 < qyx> if you want to inspire yourself https://github.com/iqyx/plumcore/blob/develop/services/cli/system_cli_tree.c
2019-01-30T23:54:18 < qyx> but beware, it is a mess
2019-01-30T23:54:23 < Ecco> How are you even supposed to use them anyway?
2019-01-30T23:54:40 < Ecco> Apply solder paste, place components manually, then put in oven?
2019-01-30T23:54:49 < qyx> I have a library to interpret such tree structured menu and make a CLI from it
2019-01-30T23:55:05 < qyx> the same structure could benused for odisplay menus
2019-01-30T23:56:38 < bitmask> it seems all your leaves have a name and an exec, its the exec for various data types I'm having trouble implementing
2019-01-30T23:57:38 < qyx> there are values, commands and subnodes
2019-01-30T23:57:47 < qyx> values can be of different types
2019-01-30T23:57:53 < qyx> uhm
2019-01-30T23:58:18 < qyx> you mean displaying a proper controp for the specific value type?
2019-01-30T23:58:33 < qyx> *control
2019-01-30T23:58:58 < bitmask> yea, if its switching between a few string options, or increasing/decreasing integer or floating point values
2019-01-30T23:59:01 < bitmask> that kinda thing
2019-01-30T23:59:46 < qyx> just do a enum type + union combination
--- Day changed Thu Jan 31 2019
2019-01-31T00:00:27 < qyx> Ecco: yes
2019-01-31T00:00:43 < Ecco> is it more convenient than hand soldering with an iron?
2019-01-31T00:00:59 < qyx> I mean your procedure is correct
2019-01-31T00:01:05 < qyx> I don't use them
2019-01-31T00:01:14 < Ecco> oh, ok :)
2019-01-31T00:01:39 < Ecco> I mean, I understand why reflowing in an oven is efficient, but that's the placing that takes forever anyway, right?
2019-01-31T00:02:10 < Ecco> also, I wonder how you can manually place components in paste without having them moving around
2019-01-31T00:03:56 < qyx> if you want to speed up hand soldering prototypes, I recommend an array of small boxes (properly marked) with components
2019-01-31T00:04:52 < qyx> then it is just a matter of few seconds to place a single SMD passive
2019-01-31T00:05:52 < Ecco> indeed
2019-01-31T00:05:55 < qyx> like a row of boxes with 0603 resistors ordered by value
2019-01-31T00:05:59 < Ecco> yeah
2019-01-31T00:06:21 < qyx> there are some on ebay
2019-01-31T00:06:29 < qyx> wen-tai marked iirc
2019-01-31T00:06:47 < qyx> they are ~good
2019-01-31T00:08:16 < bitmask> those silicone soldering mats with built in recesses look handy for doing a handful of components at a time

2019-01-31T00:09:06 < bitmask> nope
2019-01-31T00:09:47 < bitmask> that looks like way overkill for a 128x32 oled
2019-01-31T00:10:34 < bitmask> I thought of a way to do what I want, I'll create the standard menu as a linked list and when you reach a value it will call a static function to handle input with a pointer back to the linked list when you are done

2019-01-31T00:19:30 < rajkosto> thats why i switched to 128x64, x32 is too tiny
2019-01-31T00:20:17 < bitmask> its fine for what I'm doing
2019-01-31T00:20:19 < rajkosto> there was a display list library for flickerless refresh but i cant find it now
2019-01-31T00:20:22 < Steffanx> Pebkac for sure rcc
2019-01-31T00:20:24 < bitmask> I actually really like my UI
2019-01-31T00:21:05 < rcc> Steffanx: sort of, it needed the SSD to be on the first SATA port (which it was) and it had to be in AHCI mode
2019-01-31T00:21:11 < bitmask> this was before I decided to add a menu system but the main display is great: https://youtu.be/xMOiasqyowc
2019-01-31T00:21:11 < rcc> couldn't deal with RAID or IDE
2019-01-31T00:21:15 < rcc> (I had it in RAID)
2019-01-31T00:21:18 < rajkosto> rcc, it can deal with raid and ide
2019-01-31T00:21:35 < rajkosto> but dont use raid unless youre actually using raid
2019-01-31T00:21:36 < rcc> I remember I had the same issue in the past and once I switched to AHCI it worked
2019-01-31T00:21:49 < Steffanx> What kind of weird hw do you have?
2019-01-31T00:21:53 < rcc> thing is, the first time I was able to switch back to RAID after installation
2019-01-31T00:22:04 < rcc> but now it stops booting if I do that
2019-01-31T00:22:17 < rajkosto> cool amount of information about your hardware setup you have provided
2019-01-31T00:22:18 < rcc> so my raid 1 has to be relocated on a different controller
2019-01-31T00:22:39 < rcc> rajkosto, 8 HDD, 2 of them in RAID 1
2019-01-31T00:22:48 < rajkosto> what. controller.
2019-01-31T00:22:51 < rcc> two SATA controllers
2019-01-31T00:23:10 < PaulFertser> Real RAID or software?
2019-01-31T00:23:15 < rcc> sw
2019-01-31T00:23:30 < rajkosto> software what
2019-01-31T00:23:37 < PaulFertser> RAID
2019-01-31T00:23:37 < rcc> rajkosto: sw RAID
2019-01-31T00:23:48 < rajkosto> software raid what
2019-01-31T00:23:56 < PaulFertser> rcc has sw raid, not real raid
2019-01-31T00:24:03 < rajkosto> linux software raid ?
2019-01-31T00:24:04 < rajkosto> dmraid ?
2019-01-31T00:24:11 < rajkosto> lvm raid ?
2019-01-31T00:24:13 < PaulFertser> No, windows software raid.
2019-01-31T00:24:16 < rajkosto> dynamic disks ?
2019-01-31T00:24:20 < rcc> problem is that relocating the RAID on the other controller means the disks will be reinitialized, so now I have to back them up
2019-01-31T00:24:28 < rajkosto> PaulFertser, i doubt it.
2019-01-31T00:24:35 < rcc> rajkosto: I was just saying that I'm installing windows :)
2019-01-31T00:24:39 < rcc> why do you doubt that?
2019-01-31T00:24:45 < rajkosto> i doubt he has windows software raid
2019-01-31T00:24:52 < rcc> why?
2019-01-31T00:24:57 < rajkosto> if he did, it'd be controller agnostic.
2019-01-31T00:25:13 < rcc> the controller still initializes the drives tho
2019-01-31T00:25:19 < rajkosto> then its not software aid.
2019-01-31T00:25:21 < rcc> before presenting them as a raid array
2019-01-31T00:25:32 < rcc> rajkosto: it is
2019-01-31T00:25:34 < rajkosto> its either controller defined fakeRAID
2019-01-31T00:25:36 < rajkosto> or dynamic disks
2019-01-31T00:25:38 < rajkosto> please define what you have.
2019-01-31T00:25:46 < rcc> if it's not implemented by the OS, you'll see two HDDs
2019-01-31T00:25:56 < rcc> in fact, you can still access them separately

2019-01-31T00:26:16 < rajkosto> if you werent trolling, you would have said what controller and type of raid it was already
2019-01-31T00:26:23 < rajkosto> so have fun rebuilding it
2019-01-31T00:26:24 < PaulFertser> rajkosto: oh come on, fakeRAID is essentially software RAID just with shitty means of configuring it.
2019-01-31T00:26:44 < rajkosto> PaulFertser, not to windows
2019-01-31T00:26:49 < rajkosto> not to linux
2019-01-31T00:26:53 < rcc> rajkosto: I don't know what controller it is, it's provided by the MOBO
2019-01-31T00:27:00 < rcc> rajkosto: to both
2019-01-31T00:27:01 < rajkosto> then you can say what mobo it is ?
2019-01-31T00:27:07 < rcc> I've been using this setup for years
2019-01-31T00:27:13 < rajkosto> ive been using fakeRAID since 2005
2019-01-31T00:27:30 < rcc> ga 890gpa udh3
2019-01-31T00:27:35 < rcc> why do you care tho?
2019-01-31T00:27:46 < rcc> because you think it's hw raid?
2019-01-31T00:28:01 < rajkosto> its fakeraid, promise controller cuz its AMD SB
2019-01-31T00:28:14 < rajkosto> all you need to do for windows to work is load driver
2019-01-31T00:28:16 < rcc> fakeraid is sw raid, like PaulFertser said
2019-01-31T00:28:21 < rajkosto> its better
2019-01-31T00:28:24 < rajkosto> its bootable and works across OS
2019-01-31T00:28:39 < rajkosto> software raid is either dynamic disks or linux swraid partitions
2019-01-31T00:29:34 < rajkosto> what windows
2019-01-31T00:29:56 < rcc> didn't know that distinction meant that much, to me it was all the same because linux managed to fuck it up because it didn't recognize it (a couple of years back)
2019-01-31T00:30:01 < rcc> and it mounted just one of the disks
2019-01-31T00:30:12 < rcc> that's when I realized it was a soft RAID
2019-01-31T00:30:14 < zyp> no, it's worse, you get tied to a specific controller, unless you fiddle with some shit to make plain software raid mimic the on-disk layout
2019-01-31T00:30:17 < rajkosto> dmraid works automatically with all sorts of fakeRAID
2019-01-31T00:30:33 < rcc> rajkosto: except it didn't
2019-01-31T00:30:37 < rajkosto> zyp, ive been able to go from nForce raid to Intel RST to AMD SB fakeraid without rebuilding anything
2019-01-31T00:30:45 < rajkosto> dmraid is very useful
2019-01-31T00:30:54 < rcc> yeah, works fine now
2019-01-31T00:31:08 < rajkosto> rcc, what windows
2019-01-31T00:31:12 < rcc> 10
2019-01-31T00:31:21 < rajkosto> what bitness
2019-01-31T00:31:26 < rcc> had this thing with w7 too
2019-01-31T00:31:43 < rcc> 64, but why?
2019-01-31T00:32:17 < rajkosto> http://1drv.ms/1HKHD8Z
2019-01-31T00:32:36 < rajkosto> mobo in RAID mode, put that on a usb stick, "Load driver" during windows install, point it to the folder
2019-01-31T00:32:39 < rcc> zyp: so if it was hw RAID, I could have moved the drives between controllers and it would have been fine?
2019-01-31T00:32:55 < zyp> no
2019-01-31T00:33:07 < rcc> ah, that would have been great
2019-01-31T00:33:26 < rajkosto> you can move drives between controllers with the help of dmraid to swap the metadata to a different format over
2019-01-31T00:33:36 < rajkosto> hwraid is way more candid about that
2019-01-31T00:34:03 < zyp> I'm not sure how this conversation started and what the original problem is
2019-01-31T00:34:12 < rcc> rajkosto: problem is when I try to create the new RAID array, it tells me it will erase the data on the disks
2019-01-31T00:34:24 < rajkosto> why are you creating a new raid array ?
2019-01-31T00:34:31 < zyp> but I figure this hwraid vs fakeraid vs swraid dick measuring contest isn't very useful
2019-01-31T00:34:34 < rcc> zyp, I was just saying I spent 6 hours trying to install windows
2019-01-31T00:34:45 < rajkosto> because you didnt know about "Load drivers" button ?
2019-01-31T00:34:49 < zyp> there's a solution to that: don't install windows
2019-01-31T00:34:51 < rajkosto> that shows up on the disk selection page ?
2019-01-31T00:34:52 < zyp> :)
2019-01-31T00:35:04 < rcc> rajkosto, I didn't know what drivers to load
2019-01-31T00:35:07 < rajkosto> win10 should have raid drivers for all the chipsets anyway
2019-01-31T00:35:10 < rajkosto> rcc, the ones i linked you
2019-01-31T00:35:11 < rcc> also, I wouldn't expect that to be a problem in 2019
2019-01-31T00:35:27 < rcc> also, it worked before
2019-01-31T00:35:28 < rajkosto> its from here https://www.win-raid.com/t29f25-Recommended-AHCI-RAID-and-NVMe-Drivers.html
2019-01-31T00:35:32 < rcc> (with a different HDD)
2019-01-31T00:35:40 < rcc> so I assumed it was either the HDD acting up or windows

2019-01-31T00:35:43 < zyp> what sort of raid are you trying to install windows on?
2019-01-31T00:36:02 < zyp> 0? 1? 5? does fakeraid even support 6?
2019-01-31T00:36:02 < rcc> zyp, I'm not trying to install it on a RAID, the RAID was on the same controller
2019-01-31T00:36:06 < zyp> oh
2019-01-31T00:36:13 < rcc> but with the controller in RAID mode, windows won't boot
2019-01-31T00:36:19 < rajkosto> because yhou dont have the driver
2019-01-31T00:36:22 < zyp> then stop using raid mode
2019-01-31T00:36:25 < rcc> so I have to move the RAID disks to a different controller
2019-01-31T00:36:28 < zyp> and do a plain swraid instead
2019-01-31T00:36:30 < rajkosto> he cant because his raid1 will desync 
2019-01-31T00:37:07 < rajkosto> what i would have done is just disconnect the raid disks, install in ahci mode, install the driver, switch to raid mode, reboot verify it still boots, reconnect disks
2019-01-31T00:37:16 < rajkosto> or just load driver during the install 
2019-01-31T00:37:22 < zyp> yeah, that sounds reasonable
2019-01-31T00:37:27 < rcc> that's what I did
2019-01-31T00:37:29 < zyp> dumb but easy
2019-01-31T00:37:30 < rcc> minus the driver
2019-01-31T00:37:38 < rcc> it's the only thing that worked
2019-01-31T00:37:49 < rajkosto> > 2019
2019-01-31T00:37:57 < rajkosto> > not slipstreaming all the updates and drivers you need into the iso before starting the install
2019-01-31T00:38:25 < zyp> haha
2019-01-31T00:38:33 < rajkosto> for windows XP the raid drivers had to be on a FLOPPY
2019-01-31T00:38:42 < rajkosto> if you didnt slipstream
2019-01-31T00:39:18 < rcc> so what are you suggesting? MS removed the drivers from their current ISO?
2019-01-31T00:39:29 < rajkosto> win10 is a mess, it wouldnt surprise me
2019-01-31T00:39:36 < zyp> I haven't done a windows install in years, is it really that ridiculous?
2019-01-31T00:39:44 < rajkosto> the intel RST driver bundled with latest win10 is the post-optane one that doesnt work properly with RAID5, for example
2019-01-31T00:40:26 < zyp> from the way you describe it, it's less hassle to install macos on a hackintosh than it is to install windows
2019-01-31T00:40:31 < rcc> rajkosto, thing about those drivers is that I won't install them unless they come from microsoft.com or from whoever made my mobo
2019-01-31T00:40:36 < rajkosto> anyway, easily remediable by sticking the inf and sys file from that package i linked onto a usb stick and clicking "Load drivers" on the partition selection page
2019-01-31T00:40:54 < zyp> rcc, haha, what
2019-01-31T00:40:55 < rcc> zyp, yeah, it surprised me too
2019-01-31T00:40:55 < rajkosto> rcc, the ones i linked are from AMD and you can verify digital signatures
2019-01-31T00:41:10 < rajkosto> zyp, theres no fakeraid/dmraid support AT ALL on hackintosh
2019-01-31T00:41:23 < zyp> good, fuck that shit
2019-01-31T00:41:33 < rajkosto> theres also no drivers for any pci express cards that exist
2019-01-31T00:41:33 < rajkosto> so
2019-01-31T00:41:36 < rajkosto> no raid 4 u, ever
2019-01-31T00:41:52 < zyp> uh, ok
2019-01-31T00:42:23 < Steffanx> Who needs raid?
2019-01-31T00:42:25 < zyp> nevermind my 16x3TB raid then :)
2019-01-31T00:42:51 < rcc> are you serious?
2019-01-31T00:43:03 < zyp> who serious about what?
2019-01-31T00:43:11 < rcc> about that array
2019-01-31T00:43:13 < Steffanx> Thats your server... Not your hackintosh mac
2019-01-31T00:43:36 < zyp> Steffanx, yeah, but I still got it mounted on the hackintosh :)
2019-01-31T00:43:49 < Steffanx> Nfs or what?
2019-01-31T00:44:00 < zyp> after all, there are macos drivers for the 10G ethernet NIC I put into it
2019-01-31T00:44:12 < zyp> despite it being a pci express card

2019-01-31T00:44:55 < Steffanx> Same here. After i "hacked" special ids into the eeprom of the intel nic :)
2019-01-31T00:45:25 < zyp> ah, you're using the small tree drivers?
2019-01-31T00:45:32 < Steffanx> But i no more hackintosh since it didnt support my gpu
2019-01-31T00:45:32 < zyp> or whatever they were called
2019-01-31T00:45:49 < Steffanx> Yes i think so. Those rebranded intel cards
2019-01-31T00:45:57 < zyp> I remember looking at those
2019-01-31T00:46:17 < zyp> but went with some myri10g stuff instead
2019-01-31T00:46:35 < zyp> they were cheaper and had drivers that just work
2019-01-31T00:46:38 < Steffanx> I just went for what ebay had for me.
2019-01-31T00:46:46 < zyp> same
2019-01-31T00:46:49 < zyp> hmm
2019-01-31T00:47:31 < zyp> I googled, seems like there are macos drivers for the LSI HBA I've got in the server too, should I wish to stick it into the hackintosh
2019-01-31T00:47:59 < zyp> but I don't see why I want 16 noisy drives on my desk when I can have them in the other end of the house instead :p
2019-01-31T00:48:32 < zyp> rcc, does it sound so unreasonable?
2019-01-31T00:48:57 < rcc> zyp: no, it sounds great
2019-01-31T00:49:08 < rcc> I was thinking of doing something similar
2019-01-31T00:49:20 < rcc> sort of disconnect the storage from the work machine
2019-01-31T00:49:47 < zyp> it's technically just 15 drives now, I sent one in for a warranty replacement: https://paste.jvnv.net/view/rZDdX
2019-01-31T00:49:55 < zyp> should have the new one tomorrow
2019-01-31T00:49:58 < rcc> but 16 drives is a lot, that's why I wasn't sure if you're joking or not
2019-01-31T00:50:41 < rajkosto> https://images.sshnuke.net/2019-01-30_23-50-39_KsCnS1pkv.png
2019-01-31T00:50:44 < zyp> well
2019-01-31T00:51:14 < zyp> originally I were replacing a 6x1.5TB raid5 that I was tired of being full
2019-01-31T00:51:24 < rcc> zyp, what are they mounted in?
2019-01-31T00:51:27 < zyp> so I overdid it a bit to make sure I wouldn't run into the same problem again
2019-01-31T00:51:29 < zyp> in 2013
2019-01-31T00:51:37 < zyp> it's still less than half full :)
2019-01-31T00:51:56 < Steffanx> Couldve removed the porn.
2019-01-31T00:52:05 < zyp> some norco cabinet, let me find a pic
2019-01-31T00:52:37 < zyp> https://bin.jvnv.net/file/1Ubni.jpg <- here's it on a shelf in the old apartment
2019-01-31T00:53:08 < rcc> that looks neat
2019-01-31T00:53:11 < zyp> at the moment I just have it lying on the floor, planning to buy a little wheeled rack for it eventually
2019-01-31T00:54:18 < zyp> https://bin.jvnv.net/file/emEVb.JPG <- oh, and here's the NIC, had to saw out the end of the PCI slot since I only had a 4x slot free :)
2019-01-31T00:55:55 < rcc> what's that other board? more SATA ports?
2019-01-31T00:56:06 < zyp> that's the HBA for the drives
2019-01-31T00:56:11 < rcc> (they don't look like sata)
2019-01-31T00:56:17 < rcc> don't know what that is
2019-01-31T00:56:28 < rajkosto> its SAS
2019-01-31T00:56:38 < rajkosto> you can usually break those out into 2 SATA
2019-01-31T00:56:47 < zyp> they are mini-sas connectors, each carry four sas/sata lanes
2019-01-31T00:57:00 < rajkosto> anyway, big $$$ for those
2019-01-31T00:57:06 < rcc> nice
2019-01-31T00:57:14 < zyp> nah, it's fairly affordable
2019-01-31T00:57:40 < rajkosto> unless you get one of those that nobody wants because they are limited to certain motherboards unless you reflash them with hacks
2019-01-31T00:59:08 < zyp> cabinet has a backplane for each row of drives with the same connector on the other end
2019-01-31T00:59:24 < zyp> otherwise you get fanout cables with one of those in one end and four sata ports in the other
2019-01-31T00:59:32 < rcc> so here's a question, if I install the drivers now and I switch the controller back to RAID, will it still boot?
2019-01-31T00:59:40 < rajkosto> do it
2019-01-31T00:59:42 < rajkosto> you got nothing to lose
2019-01-31T00:59:46 < rcc> windows would have to recognize it on the next boot, isn't it?
2019-01-31T00:59:47 < rajkosto> if it doesnt boot just switch back to ahci
2019-01-31T01:00:11 < rajkosto> if it cant boot let it try "startup repair" once
2019-01-31T01:00:27 < rcc> I'm still backing up that RAID, once it's done, I'll give it a try
2019-01-31T01:00:30 < rajkosto> that seems to rejigger active drivers
2019-01-31T01:01:01 < rcc> linux seems to have much lower performance with NTFS than windows
2019-01-31T01:01:14 < rcc> about 5 times lower, but I'm not sure exactly what's the deal there
2019-01-31T01:01:23 < rajkosto> linux is faster for me lol
2019-01-31T01:01:34 < rajkosto> it does more caching stuff with dmraid than the intel RST driver does
2019-01-31T01:01:45 < rajkosto> judicious use of sync required
2019-01-31T01:06:30 < zyp> the fuck would you do ntfs on linux for anyway?
2019-01-31T01:06:44 < rajkosto> i still dont understand why backing up a raid1
2019-01-31T01:06:55 < zyp> because raid is not backup?
2019-01-31T01:07:07 < rajkosto> i meant specifically before "rebuilding" it
2019-01-31T01:07:11 < zyp> although, if a raid1 fails, each drive could just be accessed independently
2019-01-31T01:07:14 < rajkosto> since you can rebuild a raid1 from a single drive 
2019-01-31T01:07:18 < rajkosto> without losing any data
2019-01-31T01:07:24 < zyp> yeah
2019-01-31T01:07:24 < rajkosto> it just copies all the sectors to the 2nd drive
2019-01-31T01:07:38 < rcc> rajkosto, I don't want to risk it
2019-01-31T01:07:53 < zyp> your data, your choice :)
2019-01-31T01:08:37 < rajkosto> uninformed zoomer wastes 6 hours for not knowing how raid works or about the load driver button on the very dialog that he gets the error on
2019-01-31T01:09:03 < rcc> rajkosto: didn't know what driver to look for anyway
2019-01-31T01:09:12 < rajkosto> "amd raid driver"
2019-01-31T01:09:20 < rcc> I never looked too deep into it
2019-01-31T01:09:39 < rcc> yeah, but I assumed the SSD, which wasn't part of the RAID array, wouldn't need that
2019-01-31T01:09:47 < rcc> especially since it was working
2019-01-31T01:10:07 < rcc> the installer successfully wrote to it
2019-01-31T01:10:09 < rajkosto> btw for fakeraid, all that changing the mode from ahci to raid in the firmware setup utility does
2019-01-31T01:10:11 < rajkosto> is change the device id
2019-01-31T01:10:18 < rcc> it was just failing at random points
2019-01-31T01:10:22 < rajkosto> and also maybe enable the option rom to run before boot
2019-01-31T01:10:37 < rajkosto> the different device id lets the different driver be loaded instead of generic AHCI
2019-01-31T01:11:07 < rajkosto> oh you didnt just get no drives to choose from ?
2019-01-31T01:11:20 < rcc> no, it was working and then failing randomly
2019-01-31T01:11:22 < rajkosto> then yeah blame win10 for including unstable driver in latest win10 edition, just like they did for intel RST
2019-01-31T01:11:30 < rcc> and leaving the SSD with an incomplete install
2019-01-31T01:12:04 < rajkosto> if using XHCI and NVMe, use win8.1 instead, otherwise, win7 ;)
2019-01-31T01:14:20 < rajkosto> where do i find actual proper copper multistrand wire 28AWG with 0.8 or 1.0mm OD

2019-01-31T03:19:20 < jadew> and I couldn't find drivers for the second SATA controller (windows didn't recognize the RAID either) so I arrived to the same conclusion as zyp, fakeRAID is worse than pure sw RAID
2019-01-31T03:20:12 < jadew> the bottom line is that I switched everything to AHCI and made a sw RAID
2019-01-31T03:20:17 < jadew> and I'm copying my data back now
2019-01-31T03:24:50 < jadew> I'll have to make something to change the creation time back

2019-01-31T10:31:00 < tjq> that is the most horrid thing to ASM man
2019-01-31T10:31:12 < tjq> it is putrid.
2019-01-31T10:31:18 < zyp> old pic has banked memory, not very suitable to run C
2019-01-31T10:32:02 < dongs> i have to install some python faggotware to program it
2019-01-31T10:32:03 < dongs> wth
2019-01-31T10:32:37 < Haohmaru> i don't even get this banked memory sh*t, all i know is i couldn't make an array bigger than 256 bytes unless i modify some linker script stuff in SDCC according to some fishy alternative medicine forum post 
2019-01-31T10:35:33 < dongs> wow
2019-01-31T10:35:43 < dongs> i donno if i wanna go down the rabbithole of tinyfpga shit
2019-01-31T10:35:48 < dongs> the more i see the more i want to smash tehse boards

2019-01-31T10:36:42 < dongs> oh hahah and pcb made in kikecad, of course
2019-01-31T10:36:48 < Haohmaru> aww
2019-01-31T10:36:49 < dongs> im getting so triggered
2019-01-31T10:37:04 < jpa-> that's my definition of total pro
2019-01-31T10:39:15 < dongs> Here comes the TinyFPGA Programmer. Rather than an FTDI2232 USB interface chip it uses a PIC16F1455 USB microcontroller. While not compatible with the FTDI2232 chip, the PIC micro has a much lower BOM cost allowing the programmer hardware to be cheaper.
2019-01-31T10:39:49 < dongs> uh oh
2019-01-31T10:40:07 < dongs> Paul Stoffregen name drop
2019-01-31T10:40:17 < dongs> aids intensifies
2019-01-31T10:41:15 < jpa-> PIC16F1455 has more capable USB core than STM32: 8 bidirectional endpoints
2019-01-31T10:41:45 < Haohmaru> but is it bett0r than xmega USB
2019-01-31T10:41:59 < dongs> jpa-, but then you'd have to be using PIC

2019-01-31T10:46:28 < Haohmaru> NSFW that sh*t
2019-01-31T10:47:00 < rajkosto> that tiny fpga is too tiny to be useful
2019-01-31T10:47:15 < dongs> rajkosto: of course, its a fucking shitstarter proj
2019-01-31T10:47:22 < dongs> but im not gonna refuse free
2019-01-31T10:47:23 < dongs> however
2019-01-31T10:47:29 < dongs> i will refuse installing pyhton just to program it
2019-01-31T10:47:53 < rajkosto> only good enough to be used as glue chip
2019-01-31T10:48:02 < dongs> https://i.imgur.com/6XUNrgn.png lattice is charging $160 for a cable with this schematic
2019-01-31T10:48:03 < rajkosto> but for that, the greenpak are a better/smaller value
2019-01-31T10:48:20 < rajkosto> dongs, the xilinx platform cable is supposed to be 320$ too
2019-01-31T10:48:32 < rajkosto> clones are like 6.5$ on ebay
2019-01-31T10:48:49 < rajkosto> that has a cpld at least
2019-01-31T10:48:55 < dongs> yeah i have some gook platform cable that im sure was not $320
2019-01-31T10:49:46 < dongs> rajkosto: after getting rid of led stuff my serial2parallel mpegts stuff compiles into half of XC264A
2019-01-31T10:49:54 < dongs> so that lattice stuff would be quite suitable
2019-01-31T10:49:58 < dongs> depends whts cheaepr
2019-01-31T10:50:24 < rajkosto> you can do serial2parallel with a shift register tho
2019-01-31T10:50:30 < dongs> ah, so digikey has finally got gayified
2019-01-31T10:50:39 < dongs> rajkosto: not for specific shit Im doing wiht it
2019-01-31T10:50:47 < dongs> there's other signals taht need to follow
2019-01-31T10:52:31 < dongs> hmm xilinx cpld is more expensive at digikey
2019-01-31T10:52:33 < dongs> rip
2019-01-31T10:52:51 < rajkosto> they dont make cpld right no mor
2019-01-31T10:53:04 < dongs> XC2C64A is still available
2019-01-31T10:53:33 < dongs> ooh. but XC2C32A is even cheaper
2019-01-31T10:53:36 < dongs> lets see if my shit fits into that
2019-01-31T10:54:22 < tjq> the internet taught me
2019-01-31T10:55:53 < dongs> https://imgur.com/a/6qlBnl3 quality chinese assembly
2019-01-31T10:56:15 < Haohmaru> i see a short
2019-01-31T10:56:20 < dongs> yes, tehre's 2 of htem
2019-01-31T10:57:40 < rajkosto> 20 pcs of XC2C32A for 20 bucks
2019-01-31T10:57:50 < rajkosto> tqfp44
2019-01-31T10:57:56 < dongs> right
2019-01-31T10:59:20 < dongs> still trying to find computer-readable version of layout
2019-01-31T10:59:27 < dongs> so i can confirm if those are shorts or wat
2019-01-31T11:00:26 < rajkosto> get dat micropencil out
2019-01-31T11:00:53 < zyp> probably double grounds or something
2019-01-31T11:01:03 < rajkosto> wonder how compatible these are for running in series with a stm32 JTAG
2019-01-31T11:01:03 < zyp> since they are both connected to caps
2019-01-31T11:01:08 < rajkosto> so you can use one jtag port for b oth
2019-01-31T11:01:12 < zyp> fuck that
2019-01-31T11:01:15 < zyp> use swd
2019-01-31T11:01:29 < rajkosto> would need 2 ports for programming the 2 parts then
2019-01-31T11:01:42 < dongs> https://i.imgur.com/T5LpIjv.png i guess they'er intentional

2019-01-31T12:21:02 < Haohmaru> innovation is a successiful improvisation
2019-01-31T12:21:34 < Haohmaru> wut'cha think bout these cortex-M23 and such?
2019-01-31T12:21:53 < Haohmaru> they seem still kinda new
2019-01-31T12:24:01 < zyp> it's like a v8m M0+
2019-01-31T12:24:26 < zyp> IIRC v8m basically adds stack overflow protection and trustzone
2019-01-31T12:26:02 < zyp> stack overflow protection should help trap and debug fuckups, trustzone is probably useful if you're handling sensitive shit like crypto keys, but otherwise not all that interesting on a MCU
2019-01-31T12:27:27 < zyp> in a sense, you both need to have sensitive data and a complex enough firmware that it makes sense to split it into trusted and untrusted code
2019-01-31T12:27:38 < Haohmaru> yeah it's best if you can be conservative with RAM in general
2019-01-31T12:28:08 < zyp> so overall I don't see much of a reason to pick M23 over M0+
2019-01-31T12:28:25 < Haohmaru> i was considering a given cortex-M23 for crypto stuff, but the program size and RAM size was kinda pretty low
2019-01-31T12:28:50 < Haohmaru> so i guess it might work as a crypto-coprocessor only
2019-01-31T12:28:53 < Haohmaru> but.. meh
2019-01-31T12:29:14 < zyp> look at the larger ones then
2019-01-31T12:29:30 < zyp> I guess M33 is the next gen M4
2019-01-31T12:29:45 < zyp> and I see there's also a M35P
2019-01-31T12:29:46 < Haohmaru> yeah, i don't think i saw such when i was looking
2019-01-31T12:31:32 < Haohmaru> damn, there are literally thousands of cortex-M chips x_x
2019-01-31T12:33:02 < zyp> in general it's most useful to define your requirements first, and then pick something that fits those requirements
2019-01-31T12:33:06 < zyp> :)
2019-01-31T12:33:15 < Haohmaru> i know
2019-01-31T12:33:48 < Haohmaru> with foggy or non-existant requirements, there are still hundreds of chips that "might be suitable"
2019-01-31T12:36:59 < zyp> yes
2019-01-31T12:37:12 < zyp> nobody says you have to pick the most suitable one
2019-01-31T12:37:25 < zyp> just find something you like that fits the bill well enough and stick to that
2019-01-31T12:37:50 < Haohmaru> don't like any of them
2019-01-31T12:37:54 < Haohmaru> :~(
2019-01-31T12:38:02 < zyp> stop hating then :p
2019-01-31T12:38:39 < Haohmaru> there are infinitely many points between liking and hating something
2019-01-31T12:46:58 < Steffanx> Haohmaru stop the hate.

2019-01-31T12:47:56 < Haohmaru> maybe i would've liked them a bit more if there weren't so many gotchas in the datasheetz

2019-01-31T14:26:18 < karlp> so, share the file itself then. I gave you a nice file host linke
2019-01-31T14:26:25 < Haohmaru> karlp i can share it when i get home

2019-01-31T14:30:38 < jpa-> eh, this silicon labs sdk has "first stage bootloader", "second stage bootloader" and then also "apploader"
2019-01-31T14:30:54 < Laurenceb> overcomplex much
2019-01-31T14:31:56 < Haohmaru> jpa- that's how you launch into space
2019-01-31T14:32:29 < jpa-> it comes preprogrammed with something, but it isn't compatible with current SDK, so my BGM113 was just in infinite loop around 0x5c8 until i figured out i had to dig out and separately program a bootloader image onto it

2019-01-31T18:58:32 < bitmask> 5W/18V with a cheap 10-20A charge controller is like $30, maybe even a little less
2019-01-31T19:00:33 < emeryth> and how much is a new non-shitty battery?
2019-01-31T19:02:03 < bitmask> well if its parasitic drain then a new battery wont fix it, I am still gonna do testing before I commit to anything
2019-01-31T19:02:15 < kakimir> hmm
2019-01-31T19:02:43 < bitmask> it could be the battery (which I'm gonna have checked when I get my brakes done soon) because the car was sitting for a year outside dead. but I had battery problems before this
2019-01-31T19:03:04 < Steffanx> You have to drive more

2019-01-31T19:05:55 < kakimir> yes
2019-01-31T19:06:10 < kakimir> that also means one cycle for your battery

2019-01-31T19:07:30 < kakimir> in terms of starter battery value every full cycle might be something like 5-10eur
2019-01-31T19:07:40 < bitmask> I googled and found out my car had a problem with the hands free bluetooth unit so I checked before and I was drawing 300mA with the car off.  I unplugged it and it went down to 60
2019-01-31T19:08:16 < bitmask> I did one test after that and the car still died but I may not have fully recharged it
2019-01-31T19:08:42 < bitmask> so thats why more testing is needed first
2019-01-31T19:08:46 < kakimir> or your battery is busted
2019-01-31T19:08:51 < bitmask> could be
2019-01-31T19:09:08 < bitmask> what do places check when you bring it in? internal resistance?

2019-01-31T19:09:59 < kakimir> with color code
2019-01-31T19:10:05 < kakimir> green is good etc.
2019-01-31T19:10:13 < kakimir> also there is battery testers
2019-01-31T19:10:22 < bitmask> right, thats what I'm asking, what does it test
2019-01-31T19:10:39 < bitmask> does it do a charge/discharge cycle or something?
2019-01-31T19:10:53 < kakimir> I think those things give instant report

2019-01-31T19:46:03 < englishman> why would Keil want to support semihosting it supports real debuggers not dumb hacks
2019-01-31T19:46:52 < PaulFertser> jlink's rtt is not entirely unlike semihosting
2019-01-31T19:47:17 < Laurenceb> the absolute state https://twitter.com/meg_wain/status/1089935804099690498
2019-01-31T19:49:19 < PaulFertser> Also, there're many eval boards from manufacturers that embed dumb hacks (ft2232h) as an on-board debugger, it would be kinda silly to not support those.
2019-01-31T19:50:12 < karlp> englishman: I don't really see semihosting as a debugger, just somethign that can be useful
2019-01-31T19:50:22 < karlp> adn it's old and well defined, so yeah, I kinda expected it to work
2019-01-31T19:53:35 < jpa-> semihosting is quite useful for running automated tests on real platform or simulator; other than that, not very useful for anything requiring realtime response
2019-01-31T19:55:02 < aandrew> have any of you done non-isolated PoE supplies? I have a closed network so do not need to adhere to the isolation requirement which can bring cost down a bit

2019-01-31T19:57:58 < bitmask> when I power from 12V everything works great, if I plug usb cable into the nano to flash it then something burns

2019-01-31T20:01:05 < Cracki> bitmask, sounds like ground is fucked
2019-01-31T20:01:11 < Cracki> post a picture
2019-01-31T20:01:21 < bitmask> well its my heated hoodie electronics, so I have the nano soldered to the pcb with a 5v buck  and an oled
2019-01-31T20:01:37 < Cracki> 12v sounds isolated, usb appears not
2019-01-31T20:01:54 < Cracki> uh...
2019-01-31T20:02:03 < Cracki> you use those 12v for load too, eh?
2019-01-31T20:02:30 < bitmask> hmm the 12v plugs into the second board and ground planes are connected, that could be the problem? the 5v would be plugged into a different board
2019-01-31T20:02:31 < Cracki> look at how a nano connects vusb... it might take that as vin...
2019-01-31T20:02:40 < Cracki> and then you have load on usb power...
2019-01-31T20:03:02 < Cracki> exactly what connections are there?
2019-01-31T20:03:09 < Cracki> (to outside)
2019-01-31T20:04:36 < bitmask> there are two pcbs with grounds connected, the 12v battery connects to board A which sends power up to board B through a switch, that powers 5v buck which provides power to nano, oled and outputs 5v which goes back to board A to power thermistors and demux
2019-01-31T20:04:56 < Cracki> lol
2019-01-31T20:05:09 < Cracki> maybe that battery is powering your usb
2019-01-31T20:05:19 < Cracki> schematic perhaps
2019-01-31T20:05:20 < bitmask> the battery wasn't connected
2019-01-31T20:05:25 < Cracki> schematic.
2019-01-31T20:05:29 < Cracki> words are shit to debug.
2019-01-31T20:05:46 < bitmask> thats why I dont see how I can burn something on 5v usb but not on 12v liion :P
2019-01-31T20:05:54 < Cracki> different current paths
2019-01-31T20:06:11 < Laurenceb> https://twitter.com/5Pillarsuk/status/1090362762054774785
2019-01-31T20:06:13 < Cracki> how much current when you supply it 12v?
2019-01-31T20:06:40 < Cracki> maybe the buck doesn't like 5v on its output with nothing on input
2019-01-31T20:06:52 < bitmask> thats what I was thinking
2019-01-31T20:07:12 < bitmask> but the buck seems to be behaving correctly (still outputting 5v) when I reconnect the battery
2019-01-31T20:07:23 < Cracki> so it's not broken from that
2019-01-31T20:07:26 < bitmask> although maybe I'm killing the nano voltage reg
2019-01-31T20:07:27 < Cracki> doesn't mean it's good

2019-01-31T20:15:00 < bitmask> I know thats not a schematic but while I look you might be able to get what you need from that :P
2019-01-31T20:17:15 < Cracki> is the nano soldered in or socketed?
2019-01-31T20:17:29 < Cracki> if socketed, check if it heats out of the socket
2019-01-31T20:17:46 < bitmask> unfortunately its soldered so I cant even remove it
2019-01-31T20:18:10 < bitmask> space is too important to socket it although I should have for testing
2019-01-31T20:19:01 < bitmask> 5v usb goes through the regulator, the 5v powered from battery into buck bypasses it, that could def be it
2019-01-31T20:19:15 < bitmask> yes?

2019-01-31T20:23:58 < Cracki> I would systematically test each component for its behavior, starting with the bucks
2019-01-31T20:24:05 < Cracki> i.e. whether they like power on output
2019-01-31T20:25:40 < bitmask> hmm 3.3 on the nano is reading 3.8 and vin is reading 4.6v when supplying 5v to the 5v pin

2019-01-31T20:27:19 < bitmask> I do think the oled is damaged, I'm gonna have to remove that and test it
2019-01-31T20:27:30 < bitmask> it just flashes a random set of pixels on and off
2019-01-31T20:30:19 < Cracki> 3.3 being 3.8 sounds off...
2019-01-31T20:30:23 < bitmask> yea
2019-01-31T20:30:31 < Cracki> what kinda nano is that anyway, afaik 3.3v nanos run at 8 mhz
2019-01-31T20:30:46 < bitmask> its a 5v nano, not sure why it has a 3.3v pin, maybe for aref
2019-01-31T20:30:48 < Cracki> and the regulator is solely for turning vin (12v) into 5v
2019-01-31T20:31:03 < bitmask> some cheap china clone probably
2019-01-31T20:31:08 < Cracki> 3.3v might come out of the ch340
2019-01-31T20:32:10 < bitmask> which is what I'm thinking is damaged, I think plugging in the usb (in addition to smoking) it stopped detecting
2019-01-31T20:32:36 < Cracki> literally smoking?
2019-01-31T20:32:46 < bitmask> havent seen smoke but I can smell it
2019-01-31T20:33:03 < bitmask> what if I just flash through the icsp or whatever it is
2019-01-31T20:33:15 < Cracki> it's fucked, jim
2019-01-31T20:33:24 < Cracki> yes you can flash through the ISP header
2019-01-31T20:33:34 < Cracki> you can use another arduino for that
2019-01-31T20:34:28 < Cracki> (or get a used avrisp mk2 off ebay for cheap, or try some cheap china dongles that probably work with "avrdude")
2019-01-31T20:34:34 < bitmask> is it a bad idea to still use this arduino? if I dont use the 5v is the ch340 bypassed completely except for supplying the 3.3v?
2019-01-31T20:34:51 < bitmask> I'll just use another arduino
2019-01-31T20:34:56 < bitmask> I have a nano somewhere
2019-01-31T20:35:02 < Cracki> as long as it itself doesn't heat up...
2019-01-31T20:35:16 < bitmask> yea its been on for quite a few min now and I dont notice any heat up
2019-01-31T20:35:32 < bitmask> or smell
2019-01-31T20:35:37 < Cracki> worst that can happen is you catch fire
2019-01-31T20:35:46 < bitmask> it will just keep me warmer
2019-01-31T20:35:53 < bitmask> win win
2019-01-31T20:35:53 < Cracki> whatever heated up is probably toast now
2019-01-31T20:37:11 < Cracki> if something got fucked dead by connecting usb, it's likely the ch340/ftdi... so I'd hope the rest is still good
2019-01-31T20:37:20 < Cracki> but maybe a diode or cap was also affected
2019-01-31T20:38:19 < bitmask> the only other thing acting weird is the oled but that could just be that when I tried to flash it the ch340 was already fucked, only thing I dont get is that the upload is verified and read ok
2019-01-31T20:39:20 < Cracki> upload to arduino? then it should do its duty
2019-01-31T20:39:40 < bitmask> then I'll have to test this oled somewhere else
2019-01-31T20:41:43 < Cracki> gotta love US democrats... if they keep going, they'll legalize post-birth abortion up until the newborn has become an adult

2019-01-31T21:19:26 < aandrew> or fakes allowed for unaligned writes and genuine won't
2019-01-31T21:19:27 < aandrew> something like that

2019-01-31T21:30:33 < Cracki> that's shit
2019-01-31T21:31:48 < Cracki> and their readout poc depends on a bootloader checking crc of flash, and them watching that crc
2019-01-31T21:32:00 < Cracki> not bad, but... I'll read on
2019-01-31T21:38:06 < Cracki> so they search for the option bytes in flash... assuming flash has no wear leveling

2019-01-31T23:36:02 < englishman> powered by 9v barrel jack: can program msp430 but not stm32
2019-01-31T23:39:01 < qyx> I would say it is broken somehow, isn't it?

2019-01-31T23:40:36 < malinus> englishman: you sure that your stm32 dev board is designed to be powered by 9v?
2019-01-31T23:40:48 < malinus> maybe it's 5v (like the imxRT dev boards)
2019-01-31T23:40:51 < englishman> not a devboard and yeah
