2013-09-01T00:20:42 < Posterdati> hi
2013-09-01T00:21:45 < Posterdati> please how can I correctly set USART3 pin to use the serial port? I did TX = PORTD 8 AF_PP, RX = PORTD 9 AF_OD, ...
2013-09-01T00:22:37 < Posterdati> SR register shows TC = 1 and TXE =1 and no errors during transmitting, but TX pin is always = 0V
2013-09-01T00:24:11 < qyx_> rx should be set as input
2013-09-01T00:24:20 < qyx_> tx af output push-pull
2013-09-01T00:24:29 < qyx_> which mcu?
2013-09-01T00:24:31 < Posterdati> not AF?

2013-09-01T00:28:33 < qyx_> i was finding datasheet
2013-09-01T00:28:52 < qyx_> if you see the table 5: pin definitions
2013-09-01T00:29:10 < qyx_> portd8/portd9 are listed under remap column
2013-09-01T00:29:32 < qyx_> it means that you have to use remap capability for these ports to assign them to usart3

2013-09-01T01:56:29 < Laurenceb_> ooh nice
2013-09-01T01:56:40 < Laurenceb_> i wondered how to do that - its easy on avr
2013-09-01T01:57:55 < Laurenceb_> wait wut
2013-09-01T01:58:01 < Laurenceb_> that was too easy
2013-09-01T01:59:34 < Posterdati> yes on avr is easy
2013-09-01T02:00:50 < Posterdati> I do not know how to do that on newlib
2013-09-01T02:03:50 < Laurenceb_> do you have this working?
2013-09-01T02:05:23 < Posterdati> no
2013-09-01T02:05:37 < Laurenceb_> ah, was going to ask about binary size
2013-09-01T02:05:47 < Posterdati> what?
2013-09-01T02:05:49 < Laurenceb_> im using rfprintf from pascal stang
2013-09-01T02:05:56 < Laurenceb_> its about 1KB
2013-09-01T02:07:17 < qyx_> Laurenceb_: its already done in chibios for example, you just need to define some #define and then define some another #define with serial driver you want to use
2013-09-01T02:07:38 < Laurenceb_> actually yeah i have that working already
2013-09-01T02:07:42 < Laurenceb_> on one of my projects
2013-09-01T02:09:30 < Posterdati> qyx_: I can't use chibios, I'm on my own rtos
2013-09-01T02:09:46 < qyx_> Posterdati: but you can copy it
2013-09-01T02:09:47 < qyx_> erm
2013-09-01T02:10:01 < qyx_> you can inspire yourself

2013-09-01T03:31:10 < upgrdman> my accelerometer readings are like 20% off on my new pcb. same firmware with old pcb, and the readings were great. can accelerometers "partially" fail? im tempted to hot air swap it.
2013-09-01T03:32:58 < qyx_> there is usually a notice about accuracy/offset changes after reflowing in the datasheet
2013-09-01T03:34:37 < upgrdman> ya
2013-09-01T03:35:10 < upgrdman> but i think this is way past that. i know that "reflow stresses" can cause an offset in mems
2013-09-01T03:35:18 < upgrdman> 20% seems way off?
2013-09-01T03:35:37 < qyx_> hm, i never got that much
2013-09-01T03:36:08 < upgrdman> ya in my breakout board, and earlier pcb, the readers were very good. prolly <1% error
2013-09-01T03:36:46 < upgrdman> well it wont hurt to hot air it and let it cool down and try again
2013-09-01T03:37:12 < qyx_> you can always multiply it with some calibration matrix to get proper readings
2013-09-01T03:37:36 < upgrdman> ya but with that much error, im not sure if working around is the best idea
2013-09-01T03:37:53 < upgrdman> not that my item is critical, but still
2013-09-01T03:37:53 < qyx_> is that absolute error?
2013-09-01T03:38:15 < upgrdman> ? with the board flat, what should be 1g is like .8g
2013-09-01T03:38:20 < qyx_> or is it 20% noise when sensor is standing still?
2013-09-01T03:38:32 < upgrdman> not noise. just offset
2013-09-01T03:38:48 < upgrdman> i forgot to check with it flipped over. wonder if that'll read 1.2g
2013-09-01T03:38:48 < qyx_> and when you rotate it upside down?
2013-09-01T03:38:57 < qyx_> yep, try that
2013-09-01T03:39:01 < upgrdman> brb
2013-09-01T03:39:24 < qyx_> if it is offset or just the values are scaled down

2013-09-01T18:44:09 < emeb_mac> the main issue: I used a lot of large lookup tables that pushed the binary size over the threshold.

2013-09-01T18:44:41 < Laurenceb_> just use gnu arm embedded?
2013-09-01T18:44:48 < emeb_mac> so - try to replace the LUTs with realtime calcs, or move them into RAM and fill the tables @ boot time.

2013-09-01T23:23:05 < Ademan> Is it possible to build for the STM32F3DISCOVERY using the ubuntu package arm-linux-gnueabi-gcc ? Were I to guess, I'd assume it can't build "raw" executables suitable for flashing with stlink, but since it's packaged and I can receive updates, I'd rather use that than build the toolchain by hand
2013-09-01T23:26:38 < zyp> don't.
2013-09-01T23:26:41 < zyp> use this PPA: https://launchpad.net/~terry.guo/+archive/gcc-arm-embedded
2013-09-01T23:27:20 < zyp> https://launchpad.net/gcc-arm-embedded/ <- or just use the pre-built ones from here like everybody else

2013-09-02T00:19:36 < Posterdati> zyp: for using otg fs on stm32f107
2013-09-02T00:19:56 < zyp> are you planning on using only the usb part, or entire laks?
2013-09-02T00:20:01 -!- MrMobius [~Joey@194.176.111.172] has quit [Ping timeout: 246 seconds]
2013-09-02T00:20:07 < Posterdati> onlyy usb
2013-09-02T00:21:06 < zyp> http://cgit.jvnv.net/laks_demo/tree/?h=usb_cdc_acm <- then you might look at the F4 part of this
2013-09-02T00:21:58 < zyp> there is no F107 support in laks yet, but the usb core is the same as for F4
2013-09-02T00:22:27 < Posterdati> ok
2013-09-02T00:22:41 < Posterdati> will it work?
2013-09-02T00:23:07 < zyp> so if you're not using my code for GPIO and clocks, the main part you'll have to change is the peripheral instanciation that happens here: http://cgit.jvnv.net/laks/tree/usb/usb.h
2013-09-02T00:23:45 < zyp> the STM32F1 ifdef is for F103, so it won't work for F107, you need to instance DWC_OTG_t just like the F4 block
2013-09-02T00:24:19 < zyp> the usb block should be the same, so if you do everything right, it should work
2013-09-02T00:24:31 < Posterdati> in usb.h?
2013-09-02T00:24:53 < zyp> hmm?
2013-09-02T00:25:08 < Posterdati> I have to define STM32F4
2013-09-02T00:25:35 < zyp> or just change usb.h
2013-09-02T00:25:53 < zyp> #include "dwc_otg.h"
2013-09-02T00:25:53 < zyp> static DWC_OTG_t OTG_FS(0x50000000);
2013-09-02T00:26:00 < zyp> that's the two lines you need
2013-09-02T00:28:11 < Posterdati> ok

2013-09-02T01:47:19 < Xata> i am trying to compile demo dac code, but there is 'TIM6_DAC_IRQn' undeclared (first use in this function) error. i am using coocox with gcc-arm
2013-09-02T01:47:51 < Xata> oh. the question is how do i fix this?

2013-09-02T01:52:30 < upgrdman> i have done dac stuff, but it sounds like you need to define (or find) the void TIM6_DAC_IRQn(void){} isr
2013-09-02T01:53:13 < upgrdman> search the demo code for "TIM6_DAC_IRQn"
2013-09-02T01:54:35 < Xata> well, looks like i fixd dat. maybe in new version of gcc/ide it is TIM6_IRQn instead of TIM6_DAC_IRQn and TIM6_IRQHandler instead of TIM6_DAC_IRQHandler
2013-09-02T01:55:18 < Xata> replaced, now compiles and works. blinking leds are magnificient.

2013-09-02T02:01:43 < zyp> Posterdati, nowhere, it's just passed into a buffer that can be extracted afterwards

2013-09-02T02:02:07 < zyp> http://cgit.jvnv.net/laks/tree/gdb_plugins/rblog.py is used to extract it
2013-09-02T02:04:35 < Posterdati> ah
2013-09-02T02:19:36 < Xata> why sources and headers for HD (512k) stm32's has another word for TIM6?
2013-09-02T02:19:45 < Xata> *have
2013-09-02T02:22:23 < Xata> And what is a difference between HD and HD_VL?
2013-09-02T02:22:43 < upgrdman> vl == value line, iirc
2013-09-02T02:23:02 < upgrdman> so cheaper and presumably fewer periphs or other goodies
2013-09-02T02:24:02 < Xata> Than why VL has TIM6_DAC_IRQn and non-VL has TIM6_IRQn
2013-09-02T02:25:36 < upgrdman> maybe the non vl has separate isrs?
2013-09-02T02:26:18 < Xata> nevermind. i thought this is a problem, but looks like not. Studying stm32 is even harder than avr. but funnier.

2013-09-02T02:56:17 < Xata> Why can i have a high-freq sound on dac output? no matter what discretization freq i use? i mean - it is i.e. 1hz of actual frequency, but it is like it has very high-freq fm
2013-09-02T02:57:13 < Xata> no oscilloscope, so only i can say - led lights up/down like it should, but when i connect headphones i hear that shit
2013-09-02T02:57:28 < Xata> Also not FM, but AM. Mistyped
2013-09-02T02:59:18 < Xata> can be this because i was stupid enough to connect headphones without preamplifying?

2013-09-02T07:39:03 < emeb_mac> while the code was running free
2013-09-02T07:39:06 < dongs> right

2013-09-02T07:50:03 < dongs> mhm
2013-09-02T07:50:07 < dongs> also no surprise there
2013-09-02T07:50:18 < dongs> gcc continues to suck, news@11
2013-09-02T07:51:02 < dongs> infact, I switched to keil printf() in my shittyflyingthingproj, and it started overrunning uart buffer
2013-09-02T07:51:05 < dongs> cuz it was printing too fast.
2013-09-02T07:51:12 < dongs> before i was using some hacked up gnu printf.
2013-09-02T07:53:09 < emeb_mac> hilarious
2013-09-02T07:54:05 < emeb_mac> well, I'm not gonna stop using gcc - price is right and it runs everywhere. But it's interesting to see how keil works.
2013-09-02T07:54:18 < dongs> right.
2013-09-02T07:54:29 < emeb_mac> If I had a big project with lots riding on it I'd fork out for the pro tool.
2013-09-02T07:55:03 < dongs> i wonder if its possible to build some .obj w/keil for stuff that gcc really makes ugly
2013-09-02T07:55:09 < dongs> and link with gcc
2013-09-02T07:55:48 < emeb_mac> dunno - don't think keil speaks elf
2013-09-02T07:56:07 < dongs> sure it does?
2013-09-02T07:56:10 < dongs> axf = elf
2013-09-02T07:56:19 < emeb_mac> orly? news to me

2013-09-02T07:56:47 < emeb_mac> interesting

2013-09-02T07:58:35 < dongs> me neither thats why i dont use gcc

2013-09-02T07:59:57 < dongs> apparently with enough options keil compiler will even accepte some gcc-idiotisms
2013-09-02T08:00:24 < emeb_mac> ya - it threw a lot of warnings / errors on my gcc code when I first imported it.

2013-09-02T10:07:26 < GargantuaSauce_> Ademan: you're following me on bitbucket right...take a look at the hexapod folder
2013-09-02T10:07:39 < dongs> hexapawd
2013-09-02T10:07:53 < GargantuaSauce_> it's f4-tailored but has a pretty minimal build environment and dependencies
2013-09-02T10:08:37 < GargantuaSauce_> except ignore my newlib because it's fucked
2013-09-02T10:10:13 < GargantuaSauce_> so basically you just need system.h/c and startup.s and then headers from the csmis folder in stdperiph
2013-09-02T10:13:09 < GargantuaSauce_> (and if you want to subject yourself to the actual stdperiph library that's an option too, you just need to add c files from that to the makefile)
2013-09-02T10:14:31 < Ademan> GargantuaSauce_: hrm, think so. I'll check it out. I have stdperiph from here: http://www.st.com/web/en/catalog/tools/PF258154 sound right?
2013-09-02T10:15:28 < GargantuaSauce_> ya

2013-09-02T13:17:02 < qyx_> any idea which is the most low-end stm32 allowing both usb and can at the same time?
2013-09-02T13:17:16 < karlp> isn't the common rant, "none of them"
2013-09-02T13:18:28 < zyp> no, it's "not very low-end"
2013-09-02T13:18:33 < zyp> f107 probably
2013-09-02T13:19:06 < qyx_> hm, f107 would be ok, ill check it
2013-09-02T13:19:28 < zyp> you should be fine with either of the chips containing OTG cores
2013-09-02T13:19:34 < zyp> i.e. f107, f2 and f4
2013-09-02T13:20:01 < zyp> maybe f105 too
2013-09-02T13:20:41 < qyx_> 105/107, 1.25kbytes of dedicated sram, that looks good
2013-09-02T13:21:02 < qyx_> and 2x can with 512B of dedicated sram
2013-09-02T13:21:30 < zyp> sounds just like f4
2013-09-02T13:21:46 < zyp> (except f4 has another usb core with another 4k dedicated)

2013-09-02T17:41:23 < dongs> dont think you can
2013-09-02T17:41:25 < dongs> why would you want to?
2013-09-02T17:42:29 < dongs> its channel->CNDTR register but i duno if you can change it whlie channel is enabled
2013-09-02T17:42:42 < dongs> check RM?
2013-09-02T17:44:43 < Xata> dongs: i need this because i have a discretization frequensy and frequency of output changes by changing number of samples per waveform cycle
2013-09-02T17:45:23 < dongs> Xata: well, i told you. go see if CNDTR can be changed while DMA is running
2013-09-02T17:45:35 < Xata> that means that i.e. 440hz has 117 samples ant thus 117 is a length of buffer, and 220hz is 234 samples
2013-09-02T17:47:04 < Xata> dongs: where i can see that?
2013-09-02T17:47:45 < Xata> experimenting?
2013-09-02T17:47:49 < dongs> ? RM0090 assuming its F1
2013-09-02T17:48:06 < dongs> i mean its in reference manual
2013-09-02T17:48:11 < Wipster> Do I have the process right here in my stm32f4, set the reset bit of mac, set either RMII or MII, clear the reset bit, then enable mac tx and rx clocks?
2013-09-02T17:48:13 < dongs> for whatever chip you're on

2013-09-02T22:09:38 < Posterdati> please, I've got problem with class objects placed in global scope, their constructors are not called
2013-09-02T22:17:39 < karlp> that's probably a problem with your startup code then.

2013-09-03T02:28:59 < R2COM> I'm not quite sure why enabling EXTI interrupt inside body of another EXTI interrupt doesnt really enable it
2013-09-03T02:29:04 < R2COM> I have a piece of code:
2013-09-03T02:29:29 < R2COM> // External interrupt from pin PE4 (EXT1_IN3)
2013-09-03T02:29:30 < R2COM> SYSCFG->EXTICR[1] |= SYSCFG_EXTICR2_EXTI4_PE; //
2013-09-03T02:29:30 < R2COM> EXTI->IMR |= (1 << 4); // Mask PE4
2013-09-03T02:29:30 < R2COM> EXTI->RTSR |= (1 << 4); // Rising Edge detection
2013-09-03T02:29:30 < R2COM> NVIC_SetPriority(EXTI4_IRQn, 0x3);
2013-09-03T02:29:30 < R2COM> NVIC_EnableIRQ(EXTI4_IRQn);
2013-09-03T02:30:06 < R2COM> when that piece of code is inside EXTI2 interrupt body, EXTI4 does not get enabled (because toggling appropriate pin HIGH doesnt activate it)
2013-09-03T02:30:16 < R2COM> but when the above code is inside main body of program, it all works
2013-09-03T02:30:26 < zyp> are you sure EXTI2 gets triggered?
2013-09-03T02:30:32 < R2COM> yes I am
2013-09-03T02:31:25 < R2COM> for now I mitigated temporarily this problem in a following way: I simply created global variable, and inside EXTI2 I just set that variable to specific value, then after EXTI2 is done and program back to main body, there i check that global variable, and if its appropriate value I execute code I pasted above
2013-09-03T02:32:02 < R2COM> and then when I toggle specific pin HIGH, EXTI4 does its job
2013-09-03T02:32:16 < R2COM> which means of course that EXTI2 works properly (and I check it in debugger too)
2013-09-03T02:32:26 < zyp> ok, fair enough
2013-09-03T02:32:47 < R2COM> but should I move that piece of code from main body of program inside EXTI2, EXTI4 doesnt get enabled (because toggling that same specific pin related to EXTI4 doesnt activate it)
2013-09-03T02:33:13 < zyp> I understand what you mean
2013-09-03T02:33:14 < R2COM> EXTI2 is enabled right away when program starts in similar way as code above (just different mask, and priority 0x1)
2013-09-03T02:33:26 < R2COM> and of course SYSCFG clock is enabled right at once too
2013-09-03T02:34:00 < R2COM> stm32f407vgt6
2013-09-03T02:34:01 < zyp> so, in the case EXTI4 doesn't get enabled, does everything else keep on working?
2013-09-03T02:34:10 < R2COM> yes everything works
2013-09-03T02:34:16 < zyp> you're not triggering a crash leading to a hang?
2013-09-03T02:34:42 < R2COM> well I dont think so since I can pause and continue program after that
2013-09-03T02:35:23 < R2COM> at the beginning I thought its priority issue
2013-09-03T02:35:36 < R2COM> (like interrupt of one priority cant activate interrupt of another priority)
2013-09-03T02:35:41 < R2COM> but I checked it, its not the case
2013-09-03T02:37:46 < zyp> hmm, interesting
2013-09-03T02:38:25 < R2COM> and after that happens (failure of EXTI4 to do the job) I continue running last infinite loop
2013-09-03T02:38:31 < R2COM> and debugger does not spit out anything nasty
2013-09-03T02:38:36 < R2COM> just as always continue running
2013-09-03T02:38:42 < zyp> and other irqs are still handled?
2013-09-03T02:38:44 < R2COM> can stop then continue again
2013-09-03T02:39:37 < R2COM> yes
2013-09-03T02:40:41 < R2COM> I gone through docs, didnt find any mentioning about when its allowed to turn on/off interrupts from inside of another interrupts
2013-09-03T02:40:50 < zyp> hmm, according to the CMSIS documentation, SetPriority expects the priority argument to be left aligned
2013-09-03T02:41:08 < R2COM> left aligned?
2013-09-03T02:41:10 < R2COM> well
2013-09-03T02:41:18 < zyp> stm32 only implements four bits (the upper four), so a priority of 0x03 will be equal to 0x00
2013-09-03T02:42:02 < R2COM> I think that function I use is top wrapper
2013-09-03T02:42:11 < R2COM> it does the alignment already itself
2013-09-03T02:42:15 < R2COM> that NVIC stuff
2013-09-03T02:42:21 < R2COM> NVIC_SetPriority(EXTI4_IRQn, 0x3);
2013-09-03T02:42:33 < zyp> if so, that's not compliant with the CMSIS
2013-09-03T02:42:57 < R2COM> ok I can real quick check with 0x1 and 0x2
2013-09-03T02:43:03 < R2COM> EXTI2 will be 0x1
2013-09-03T02:43:07 < R2COM> EXTI4 will be 0x2
2013-09-03T02:43:11 < zyp> but anyway, it should not be a priority issue anyway
2013-09-03T02:43:48 < R2COM> I think so because I tried flipping their priorities already
2013-09-03T02:45:54 < emeb> when you return from interrupt, the previous state of IRQ enables isn't restored is it?
2013-09-03T02:46:26 < zyp> no, it's not saved anywhere
2013-09-03T02:46:36 < zyp> you can't restore anything you haven't saved
2013-09-03T02:46:40 < emeb> ya
2013-09-03T02:47:18 < Posterdati> zyp: linker complains about entry :) /opt/gcc-arm-none-eabi-4_7-2013q1/bin/../lib/gcc/arm-none-eabi/4.7.3/../../../../arm-none-eabi/bin/ld: warning: cannot find entry symbol entry; defaulting to 08000150
2013-09-03T02:47:20 < R2COM> when I put that code inside body of EXTI2 I even checked for IMR and RTSR right after setting them, to make sure they have proper mask (that mask is actually set) it was right
2013-09-03T02:47:35 < Posterdati> zyp: that is strangely correct
2013-09-03T02:47:36 < zyp> Posterdati, then you're doing something wrong
2013-09-03T02:47:40 < R2COM> and then after that two NVIC functions
2013-09-03T02:48:10 < emeb> so presumably the RTI is somehow blowing away the settings you made?
2013-09-03T02:48:18 < R2COM> RTI?
2013-09-03T02:48:22 < R2COM> whats that
2013-09-03T02:48:25 < emeb> return from interrupt
2013-09-03T02:48:49 < zyp> no reason it should
2013-09-03T02:48:52 < emeb> just shorthand - don't think there's actually an instruction called that.
2013-09-03T02:48:57 < emeb> and yet...
2013-09-03T02:49:09 < zyp> I think there is something missing here
2013-09-03T02:49:22 < zyp> something happening that we're not aware of
2013-09-03T02:50:17 < zyp> I would try reproducing it here, but I don't have time for it now
2013-09-03T02:50:30 < emeb> how very Fermat of you. :)
2013-09-03T02:52:40 < zyp> debugging a live local case of a problem is much easier than having people doing the debugging and relaying the information leaving out important clues ;)
2013-09-03T02:54:17 < R2COM> also I was wondering if accessing SYSCFG and EXTI registers might not be always acceptable maybe in some cases from inside interrupts
2013-09-03T02:54:39 < zyp> no reason that should be a problem
2013-09-03T02:55:05 < zyp> SYSCFG and EXTI registers are just peripherals, external to the CPU core, they don't know anything about the processor state

2013-09-03T04:18:58 < ShiftPlusOne> So... since VDD is 3V, max on the 5v tolerant pins is actually 7V, which seems quite generous. Should've consulted the datasheet first, sorry.
2013-09-03T04:21:33 < Posterdati> ShiftPlusOne: anyway str912 is 5V tollerant too, but it act strangely when certain pins were connected to 5V

2013-09-03T05:17:41 < xata> Hello again. Is there any way to measure cpu load without hardware debugger? I have no debugger, and i have a suspition, that doing sin and double math in 44100realtime is a bit too much for f103
2013-09-03T05:18:27 < talsit> there's a register which is a hardware cycle counter
2013-09-03T05:18:41 < talsit> you can get the difference of before/after your code
2013-09-03T05:18:45 < R2COM> maybe setting the outputs in a fast way with BSSR and looking at scope? just to ecaluate delays..
2013-09-03T05:18:45 < talsit> and find out
2013-09-03T05:20:39 < xata> R2COM, if only i had a scope.
2013-09-03T05:21:13 < talsit> 10,000,000 iterations and a stopwatch?
2013-09-03T05:25:14 < xata> talsit, that rwgister, i can find out amount of cycles for math by substraxting pre-math amount from post-math, right?
2013-09-03T05:25:24 < talsit> yep
2013-09-03T05:26:54 < talsit> i think it's called DWT_CYCCNT on the f1's
2013-09-03T05:26:59 < talsit> but check
2013-09-03T05:29:13 < xata> Only thing is how do i see the result. I hope it will be less than 16bit, so i can drive it to port and set the leds on it. Or maybe i'll use hd47780. Well, thanks - i have to find that register now.
2013-09-03T05:31:17 < talsit> if it's more than 16bit, you can divide by 1000, for example, to get you in the range
2013-09-03T05:31:49 < talsit> and i would iterate a few times over your algorithm, in case you're getting denormals and stuff in specific areas
2013-09-03T05:35:12 < xata> Well, i had it silent instead of glitchy or slow sound.
2013-09-03T05:38:02 < xata> Last question before i fall asleep - more about C maybe. If i make a, for example 10kb array and start it on device with 8kb of memory it will not work. But i just need to read that array. So if i declare it const - will whole array load to memory?
2013-09-03T05:38:44 < talsit> are you talking about storing it in flash instead of sram?
2013-09-03T05:39:35 < xata> Yes. Stupid question maybe, but i am amateur
2013-09-03T05:40:16 < talsit> try it, declare a 10k array as const, then, if it links, find out it goes
2013-09-03T05:40:54 < talsit> you can use a command like "arm-none-eabi-objdump -t <elf>.elf | gsort -k5"
2013-09-03T05:41:02 < talsit> to find out sizes of stuff
2013-09-03T05:41:08 < talsit> or just look at your .map
2013-09-03T05:46:47 < xata> talsit, i see. Thank you for your help

2013-09-03T08:09:39 < emeb_mac> cool
2013-09-03T08:09:56 < R2COM> reason I need lots of connectors is lots of smaller boards

2013-09-03T08:12:05 < emeb_mac> then I want to design a little front-end board for it - amps, tuners, mixers, etc.
2013-09-03T08:12:29 < R2COM> why 20MHz bw?
2013-09-03T08:12:42 < emeb_mac> the ADC is 40MSPS max. :)
2013-09-03T08:13:05 < emeb_mac> wanted to start out with a cheap & available ADC
2013-09-03T08:13:07 < R2COM> whats its bandwidth?
2013-09-03T08:13:30 < emeb_mac> front end BW for subsampling is good out to 170MHz I think
2013-09-03T08:14:04 < emeb_mac> not great as such things go.

2013-09-03T08:15:55 < R2COM> then why to do this?
2013-09-03T08:16:10 < emeb_mac> but you can undersample a narrow BW signal whose frequency > sample rate.

2013-09-03T08:27:24 < emeb_mac> or was that just different marker freqs?
2013-09-03T08:27:43 < R2COM> no. at those markers response before was much worse
2013-09-03T08:27:48 < R2COM> reflection was -7dB
2013-09-03T08:28:01 < R2COM> (at passband of interest - between markers)
2013-09-03T08:28:17 < R2COM> now it starts for each filter at -10dB and goes down
2013-09-03T08:29:06 < emeb_mac> was that the 2L or 4L process?
2013-09-03T08:29:11 < R2COM> 4l
2013-09-03T08:29:36 < emeb_mac> what was the char impedance of the traces you used?
2013-09-03T08:29:43 < R2COM> 50
2013-09-03T08:29:47 < emeb_mac> huh

2013-09-03T08:30:14 < emeb_mac> seems like those traces are narrower than I would have thought for the layer spacing in the 4L process.
2013-09-03T08:30:35 < R2COM> they will be. that had to be that way. but in general connecting lines are a bit bigger
2013-09-03T08:30:42 < R2COM> 2 mil bigger
2013-09-03T08:32:28 < R2COM> filters are usable anyhow. its just I expected better results
2013-09-03T08:32:39 < emeb_mac> *nod*
2013-09-03T08:33:13 < emeb_mac> was talking to an RF guy the other day - he said he tried to get firm layer specs from OSHpark but they wouldn't give 'em
2013-09-03T08:33:32 < emeb_mac> so he gets his close tolerance stuff from someone else.
2013-09-03T08:33:35 < R2COM> no they wont, because I guess they dont know too they use different fabs I guess
2013-09-03T08:33:44 < emeb_mac> could be
2013-09-03T08:34:32 < R2COM> amplitude response wasnt much importnat  for me, since I can do almost brick filter in digital domain
2013-09-03T08:35:12 < emeb_mac> aha. you were more interested in low insertion loss?
2013-09-03T08:35:32 -!- alexn [~alexn@93.104.205.194] has joined ##stm32
2013-09-03T08:35:59 < R2COM> well yes, actually in amplitude response too, but amplitude response just had to be good enough to prevent subsequent to filter component from spurs
2013-09-03T08:36:04 < R2COM> and this response is ok for that
2013-09-03T08:36:45 < R2COM> for precise filtering I would use digital one anyhow
2013-09-03T08:36:56 < emeb_mac> ya
2013-09-03T08:37:11 < R2COM> also theres like 8dB loss in passband, according to my simulations it had to be like 4 or so
2013-09-03T08:37:57 < R2COM> but I can arrange the channel in such a way that I wont need attenuator in another place, so its not a big deal
2013-09-03T08:38:17 < emeb_mac> just got done doing a design for a VHF comms digital frontend - 50MSPS that decimates to 48kHz w/ very selective filters.
2013-09-03T08:42:09 < R2COM> so, I will need maybe to find another fab for some other things
2013-09-03T08:42:21 < R2COM> for prototyping
2013-09-03T08:42:49 < emeb_mac> ya
2013-09-03T08:43:14 < emeb_mac> wonder who's good for tight tolerance RF work, but reasonably priced?
2013-09-03T08:43:39 < R2COM> noone.
2013-09-03T08:43:57 < emeb_mac> heh
2013-09-03T08:44:04 < emeb_mac> bring $$$
2013-09-03T08:44:46 < R2COM> or know how to get stuff done/tweaked on cheap process
2013-09-03T08:45:02 < emeb_mac> there's that.
2013-09-03T08:45:16 < emeb_mac> man - Mini-Circuits website sucks so hard.
2013-09-03T08:45:32 < emeb_mac> looks like it was designed in 1994
2013-09-03T08:45:34 < R2COM> why
2013-09-03T08:45:50 < R2COM> I'm used to it already its kinda ok
2013-09-03T08:46:26 < R2COM> use hittite website if you dont like it ;)
2013-09-03T08:48:14 < emeb_mac> they make some cute stuff
2013-09-03T08:48:21 < R2COM> also
2013-09-03T08:48:32 < R2COM> there are plenty companies which do some specific custom stuff
2013-09-03T08:48:35 < R2COM> if its that badly needed
2013-09-03T08:48:42 < R2COM> filter with needed freq/type etc
2013-09-03T08:48:48 < R2COM> but again they will charge a lot
2013-09-03T08:49:30 < emeb_mac> yep
2013-09-03T08:49:45 < emeb_mac> I remember buy custom cut xtals in the past
2013-09-03T08:50:01 < emeb_mac> was actually rather reasonable considering.
2013-09-03T08:52:07 < R2COM> found some better deal
2013-09-03T08:52:10 < R2COM> for rf sma
2013-09-03T08:52:13 < R2COM> 1.4$ each
2013-09-03T08:52:23 < R2COM> 35$ for 25 pcs
2013-09-03T08:52:27 < emeb_mac> size / spacing correct for your app?
2013-09-03T08:52:43 < emeb_mac> those Johnson parts looked iffy
2013-09-03T08:52:44 < R2COM> well I think all through hole connectors should be same
2013-09-03T08:52:51 < R2COM> why iffy?
2013-09-03T08:52:59 < R2COM> they just looked kinda circled....
2013-09-03T08:53:00 < emeb_mac> Oh - you wanted th, not edge
2013-09-03T08:53:09 < R2COM> I would buy edge too
2013-09-03T08:53:14 < R2COM> but now thru
2013-09-03T08:53:24 < R2COM> what I am saying is those johnson looked cirlced
2013-09-03T08:53:31 < emeb_mac> ya
2013-09-03T08:53:45 < R2COM> but I guess as far as pitch between 4 legs and center one is same as in squared...it shouldnt be problem
2013-09-03T08:53:47 < R2COM> I assume..
2013-09-03T08:54:16 < R2COM> oh wait... "used"
2013-09-03T08:54:19 < R2COM> hmmm
2013-09-03T08:54:30 < emeb_mac> wtf?
2013-09-03T08:54:39 < R2COM> they looked new though dont see any solder on legs
2013-09-03T08:54:52 < emeb_mac> maybe just NOS?
2013-09-03T08:54:56 < R2COM> NOS=?
2013-09-03T08:55:02 < emeb_mac> new old stock
2013-09-03T08:55:14 < emeb_mac> ie bought, inventoried & resold unused.
2013-09-03T08:57:20 < R2COM> sent a question already
2013-09-03T09:02:28 < emeb_mac> whoa - Serena Williams on Letterman tonite. She looks like she could crush him like a bug.
2013-09-03T09:03:22 < R2COM> what??

2013-09-03T10:20:49 < R2COM> As the federal ministry of economics and technology granted 2 million € as a
2013-09-03T10:20:49 < R2COM> subsidy of the project-related costs, e-volo is working together with a research
2013-09-03T10:20:49 < R2COM> and industry syndicate to build the VC200, the first Volocopter in the world to
2013-09-03T10:20:49 < R2COM> carry two people.
2013-09-03T10:21:11 < R2COM> useless shit
2013-09-03T10:21:27 < R2COM> 2M euros...
2013-09-03T10:21:30 < R2COM> cool.
2013-09-03T10:21:47 < emeb_mac> 18-copter!
2013-09-03T10:22:27 < R2COM> maybe price
2013-09-03T10:22:38 < R2COM> maybe it will be way cheaper than conventional average 2-seted heli
2013-09-03T10:23:12 < emeb_mac> all I can afford is a beanie w/ propeller
2013-09-03T10:23:26 < jpa-> maybe.. or maybe less fuel usage or less noise?
2013-09-03T10:23:32 < R2COM> I wonder if 2M euros were spent to research a better/safer engines used for jetPack, and have two of those attached to same cabin... would possibly maybe to achieve same result but without that huge construction around

2013-09-03T12:00:43 < zyp> no, that's not the problem, that's perfectly valid
2013-09-03T12:00:50 < Posterdati> ok
2013-09-03T12:01:12 < Posterdati> ctors table starts at 0x0800150
2013-09-03T12:01:19 < Posterdati> ctors table starts at 0x08000150
2013-09-03T12:01:24 < zyp> "blx <label>" is not valid on cortex-m, "blx <register>" is fine
2013-09-03T12:01:36 < zyp> and your "blx r3" is the latter kind
2013-09-03T12:02:46 < Posterdati> r3 = 0x80001dc
2013-09-03T12:02:55 < Posterdati> that it is valid
2013-09-03T12:03:11 < zyp> that's not valid
2013-09-03T12:03:30 < Posterdati> should be 0x80001dd?
2013-09-03T12:03:38 < Posterdati> to stay in thumb mode?
2013-09-03T12:03:45 < zyp> yep
2013-09-03T12:03:53 < Posterdati> why it is 1dc?
2013-09-03T12:04:06 < zyp> because you're doing something wrong
2013-09-03T12:04:19 < Posterdati> I used your ld script
2013-09-03T12:04:32 < zyp> either you've messed up the linker script, or you are not compiling with the correct flags
2013-09-03T12:04:39 < zyp> probably the latter
2013-09-03T12:04:44 < Posterdati> ok
2013-09-03T12:04:51 < Posterdati> which are the correct flags?
2013-09-03T12:05:33 < zyp> http://cgit.jvnv.net/laks/tree/build_rules <- lines 24-27
2013-09-03T12:09:33 < Posterdati> ok
2013-09-03T12:09:41 < Posterdati> I misplaced -nostartfiles
2013-09-03T12:09:49 < Posterdati> and no -ffunction-sections
2013-09-03T12:09:58 < zyp> not sure those matters
2013-09-03T12:10:27 < zyp> important part is that both compile and link commands need -mcpu and -mthumb
2013-09-03T12:11:00 < Posterdati> r3 = 0x800b471
2013-09-03T12:11:34 < zyp> that sounds better
2013-09-03T12:11:56 < Posterdati> I'm now in __static_initializaztion_and_destruction_0
2013-09-03T12:12:03 < zyp> sure
2013-09-03T12:12:17 < Posterdati> the table of ctors seems to work
2013-09-03T12:12:24 < Posterdati> now
2013-09-03T12:12:53 < zyp> good
2013-09-03T12:12:55 < Posterdati> to add interrupts have I to use set_handler function?
2013-09-03T12:13:09 < zyp> no
2013-09-03T12:13:45 < Posterdati> or just interrupt<IRQ:XXXXX>() { }
2013-09-03T12:14:28 < Posterdati> they are all weak so a new definition wil suupersede the entry in the vectors array
2013-09-03T12:14:37 < Posterdati> is it correct?

2013-09-03T12:20:18 < Posterdati> nice
2013-09-03T12:25:05 < Posterdati> zyp: thanks
2013-09-03T12:25:05 < zyp> Posterdati, yes, that is correct, the set_handler stuff is unrelated
2013-09-03T12:25:45 < Posterdati> zyp: the toolchain you suggested to me is perfect
2013-09-03T12:26:06 < Posterdati> zyp: I'm very happy of that
2013-09-03T12:26:14 < Posterdati> zyp: codesourcery was a mess
2013-09-03T12:26:18 < zyp> dongs, what resolution is that
2013-09-03T12:29:50 < Posterdati> zyp: didn't work! after executing usb constructors it jams :(
2013-09-03T12:30:16 < zyp> then you're still doing something wrong
2013-09-03T12:31:32 < Posterdati> f107 has got only OTG_FS
2013-09-03T12:31:56 < Posterdati> I removed static DWC_OTG_t OTG_HS(0x40040000);
2013-09-03T12:32:10 < zyp> that's fine
2013-09-03T12:33:45 < dongs> zyp: just 1080piss 13". but its a paidproj so i dont care
2013-09-03T12:33:53 < dongs> 4x dp-> power/control
2013-09-03T12:34:00 < zyp> ah
2013-09-03T12:34:09 < zyp> yeah, saw the board had four ports
2013-09-03T12:34:34 < dongs> also uses that allegro current sensor
2013-09-03T12:34:39 < dongs> to see if BL is on on panel or not
2013-09-03T12:34:52 < dongs> the one with weird footprint
2013-09-03T12:35:05 < zyp> what weird footprint?
2013-09-03T12:35:43 < dongs> acs711
2013-09-03T12:35:49 < qyx_> it is soic8, isnt it?
2013-09-03T12:35:55 < qyx_> 758 is weird
2013-09-03T12:35:55 < dongs> http://www.allegromicro.com/~/media/Images/Products/0711/ACS711-Product-Image-2.ashx
2013-09-03T12:35:59 < dongs> no
2013-09-03T12:36:09 < zyp> oh, wow
2013-09-03T12:36:23 < qyx_> wut, i used the same in soic
2013-09-03T12:36:27 < zyp> weirdest qfn I've seen so far
2013-09-03T12:36:31 < dongs> oddly it was cheapest of hte bunch
2013-09-03T12:36:37 < dongs> so i went for it
2013-09-03T12:37:29 < Posterdati> zyp: it hangs during a std::pair initializzation
2013-09-03T12:38:11 < zyp> huh, I'm not using std::pair anywhere
2013-09-03T12:38:31 < Posterdati> no my code
2013-09-03T12:39:03 < dongs> the fuck are you using STL
2013-09-03T12:39:06 < dongs> on embedded?!?#!!@$
2013-09-03T12:48:57 < jpa-> it's not that bad
2013-09-03T12:49:05 < jpa-> a bit bloat but works fine
2013-09-03T12:49:26 < jpa-> when one has 1 MB of flash, who cares

2013-09-03T13:56:02 < Posterdati> shall I clear SysTick IRQ flag or it is automatic?

2013-09-03T13:56:07 < dongs> automatic
2013-09-03T13:56:12 < dongs> and i still seeno issues
2013-09-03T13:56:13 < zyp> so, which one were more power consuming? black?
2013-09-03T13:56:18 < dongs> white
2013-09-03T13:56:39 < dongs> maximizing IE makes more power
2013-09-03T13:56:44 < dongs> maximizing black chat window, less
2013-09-03T13:56:44 < Posterdati> then why it jumps suddenly to systick handler after executing it?

2013-09-03T14:01:49 < dongs> oh, asus
2013-09-03T14:02:31 < dongs> i need to finish hid firmware
2013-09-03T14:02:35 < dongs> so i can control brightness remotely
2013-09-03T14:02:44 < dongs> or maybe ill just hookup debugger or something
2013-09-03T14:02:50 < dongs> at least this one has bulit in driver, and just needs pwm to change it
2013-09-03T14:02:59 < zyp> nice

2013-09-03T14:03:24 < zyp> what's all the stuff on the board for then? just individual regs for each panel?

2013-09-03T14:03:49 < dongs> 3.3V for mcu

2013-09-03T14:04:17 < dongs> this is some bullshit industrial crap so the guy wanted to be able to remotely check if shit is running

2013-09-03T17:26:54 < dongs> i didnt write any of the asm, i just copypasted it.
2013-09-03T17:26:54 < dongs> like a pro.
2013-09-03T17:27:01 < Posterdati> lol
2013-09-03T17:28:01 < Posterdati> stm32f is a very good platform, very cost effective
2013-09-03T17:28:23 < Posterdati> at first I was scared just because I came from str912 experience
2013-09-03T17:28:25 < dongs> but it cant run lunix
2013-09-03T17:28:27 < dongs> so its usleess.
2013-09-03T17:28:52 < dongs> tho i guess nuttx will get you pretty close to lunix
2013-09-03T17:29:25 < Posterdati> I love linux to develop, so amazing

2013-09-03T18:03:53 < karlp> my new laptop boots stupid fast, loving the SSD
2013-09-03T18:03:57 < trepidaciousMBR> I can show random text in a serial console that looks a bit like Linux in 1msec!
2013-09-03T18:04:19 < trepidaciousMBR> Interesting though, I didn't know anyone was bothering with linux on STM32
2013-09-03T18:04:57 < karlp> ds2 was wasn't he? stm have uclinux example code, and embedded artists sell a BSP don't they?
2013-09-03T18:05:24 < karlp> or was it emcraft? ;)
2013-09-03T18:06:11 < trepidaciousMBR> emcraft for that video
2013-09-03T18:06:26 < trepidaciousMBR> They make some kind of module
2013-09-03T18:07:08 <+Steffanx> Still i wouldn't use a stm32f4 for that.

2013-09-03T18:09:42 <+Steffanx> some random company..
2013-09-03T18:10:11 < Laurenceb_> if you could run from internal memory its veyr low power
2013-09-03T18:10:29 < Laurenceb_> but then you have limited ram - apparently its hard to get busybox to run
2013-09-03T18:11:09 <+Steffanx> stm32f4x9 to the rescue
2013-09-03T18:11:10 <@Tectu> new F4 do have SDRAM
2013-09-03T18:11:14 <@Tectu> could be interesting
2013-09-03T18:11:18 <@Tectu> (for that)
2013-09-03T18:11:31 <+Steffanx> Just as interesting as the raspberrypi? :P

2013-09-03T18:15:16 < trepidaciousMBR> Laurenceb: Power hungry?
2013-09-03T18:15:37 < trepidaciousMBR> I'd really like SDRAM rather than PSRAM - for example, the part they have on that module is EOL
2013-09-03T18:15:38 <+Steffanx> > 1µW :)
2013-09-03T18:15:41 < trepidaciousMBR> :)
2013-09-03T18:16:49 <+Steffanx> I wonder why it took so long from ST to come with an SDRAM controller. Even the (now) old 8-bit xmega has it. And some other 8-bit probably before that.

2013-09-03T18:18:13 < trepidaciousMBR> Presumably it's not THAT much extra cost to add an SDRAM controller?
2013-09-03T18:19:33 < trepidaciousMBR> I've not really looked for suitable SDRAM for a 4x9, any ideas?
2013-09-03T18:20:13 < Posterdati> zyp: now, how can I use the cdc as serial input output? Have you got any example? Thanks for the help

2013-09-03T21:09:12 <+Steffanx> or is someone uploading crappy data?
2013-09-03T21:09:20 < Laurenceb_> its because it some of the positions were logged onboard
2013-09-03T21:09:26 < Laurenceb_> when it went out of range
2013-09-03T21:09:40 < Laurenceb_> and uploading them later screwed up the server

2013-09-03T23:33:58 < emeb> my DSP code seems to run slightly slower on Keil than it does on gcc

2013-09-04T03:11:53 < Lt_Lemming> sooo amusing one I just discovered...
2013-09-04T03:12:19 < Lt_Lemming> TI's Cheapest Cortex based µC... is $2 more than STM's highest end one on digikey
2013-09-04T03:12:33 < Lt_Lemming> and it has 1/2 the flash and 1/3 the RAM
2013-09-04T03:12:54 < emeb> But TI is so much better!
2013-09-04T03:13:00 < emeb> </irony>
2013-09-04T03:13:01 < Lt_Lemming> yeah
2013-09-04T03:13:09 < Lt_Lemming> someone was bending my ear about that last night
2013-09-04T03:13:20 < Lt_Lemming> going on about how the TI chips have a built in PHY...
2013-09-04T03:13:27 < Lt_Lemming> that's a damned expensive PHY!

2013-09-04T03:18:41 < dongs> thats ok tho only 67 hours left
2013-09-04T03:18:46 < dongs> they will die a fiery death
2013-09-04T03:18:49 < emeb> not holding my bref
2013-09-04T03:21:10 < qyx_> lol
2013-09-04T03:22:53 < Alexer> dongs, I'm not familiar with the project, but out of curiosity, why should it die a fiery death?
2013-09-04T03:23:03 < dongs> Alexer: its a waste of people's money.
2013-09-04T03:23:10 < dongs> stm32discovery is $9.90
2013-09-04T03:23:12 < dongs> and does more
2013-09-04T03:23:14 < dongs> and has more IO
2013-09-04T03:23:21 < dongs> AND has a built in debugger
2013-09-04T03:23:30 < dongs> this trash is just a stm32f103c8/cb breakout
2013-09-04T03:23:40 < dongs> without even debug broken out
2013-09-04T03:23:52 < dongs> their "salespoint" is some usb mass storage bootloader for flashing
2013-09-04T03:23:56 < dongs> i.e. shit they stole from mbed
2013-09-04T03:24:59 < Alexer> doesn't the discovery license forbid you to use it for anything commercial or something?
2013-09-04T03:25:14 < dongs> who the fuck would use that shit for anything commercial
2013-09-04T03:25:23 < dongs> its a development boardf.
2013-09-04T03:25:41 < emeb> well, a lot of n00bs with big ideas are afraid of SMT
2013-09-04T03:26:05 < emeb> so they'd rather buy 0.1" PTH breakouts for their big commercial success.
2013-09-04T03:26:19 < emeb> not saying that's sane
2013-09-04T03:27:18 < dongs> fuck off.
2013-09-04T03:28:04 < Alexer> dongs, there are more than 7 billion people on this planet, I bet there are a few :P
2013-09-04T03:30:16 < Alexer> I mean, people use arduinos inside commercial projects
2013-09-04T03:40:42 < Alexer> but yeah, not something I'd buy
2013-09-04T03:41:45 < dongs> pretty sure not something anyone in THIS channel would buy
2013-09-04T03:43:35 < emeb> and if they did we'd point & laugh

2013-09-04T04:52:47 < dongs> oh, i got a hilarity
2013-09-04T04:52:55 < dongs> this one guy emails me almost daily about a lot of irrelevant shit

2013-09-04T04:53:21 < emeb_mac> and he still keeps on
2013-09-04T04:53:25 < dongs> so yesterday he emails me and like oh i hope im not disturbing but I checked out your linkedin and it says you're in israel now, i hope youre not affected by SYRIA stuff.

2013-09-04T04:55:07 < dongs> why teh shit does it have 2 giant linear regulators

2013-09-04T04:55:51 < emeb_mac> blargh
2013-09-04T04:55:57 < emeb_mac> has on-board 5V reg
2013-09-04T04:55:59 < emeb_mac> useless
2013-09-04T04:57:19 < dongs> does prop fucking run off 5V
2013-09-04T05:00:22 < emeb_mac> no - it's 3.3V. text seems to suggest 5V reg is for peripherals (LCD, servo, etc)
2013-09-04T05:00:45 < dongs> whatever. still garbage
2013-09-04T05:07:12 < emeb_mac> it's an interesting idea. trouble is that it's so different from most MCUs that it's hard to use. Plus, no basic peripherals like SPI, I2C, etc - everything must be done by programming the "cogs"
2013-09-04T05:07:27 < dongs> right

2013-09-04T07:41:48 < R2COM> just wonder why it was doing this
2013-09-04T07:42:14 < R2COM> I might change it to another similar one
2013-09-04T07:42:29 < R2COM> or. in a worst case just remove it. and give it 3.3V from any other available source

2013-09-04T07:58:45 < R2COM> yes
2013-09-04T07:59:13 < R2COM> its also one of the types of regs which can be parallelized. but then you have to implement precise resistance control with traces
2013-09-04T07:59:17 < R2COM> but it wasnt needed in my case
2013-09-04T07:59:23 < R2COM> since I had one of it
2013-09-04T07:59:52 < R2COM> I didnt have to use this reg on this board at all I just was curious to try since I needed some 3.3v real purpose of board is just act as adapter
2013-09-04T08:00:02 < R2COM> removed it already, gave separate 3.3v to buffers
2013-09-04T08:02:06 < emeb_mac> R2COM: do you have a load on that regulator?
2013-09-04T08:02:21 < R2COM> very small load
2013-09-04T08:02:46 < emeb_mac> check the data sheet - some LDOs fall out of regulation with very low currents.
2013-09-04T08:03:05 < R2COM> this one isnt
2013-09-04T08:03:12 < R2COM> I even simulated its model
2013-09-04T08:03:36 < R2COM> with like 1uA
2013-09-04T08:03:39 < R2COM> load

2013-09-04T08:07:46 < dongs> praise the load
2013-09-04T08:08:49 < dongs> of all the dumb shit you coulda selected to get 3.3V
2013-09-04T08:08:52 < dongs> like say a LM1117
2013-09-04T08:08:57 < dongs> you chose that dumb lnear part
2013-09-04T08:09:43 < dongs> i mean i realize spacex has a bunch of cash thanks to my paypal account but does that mean you ahve to waste it
2013-09-04T08:09:45 < R2COM> I was about to complete board, then noticed that reg and kinda randomly put it in
2013-09-04T08:10:22 < R2COM> 3.3v wasnt priority on that board at all
2013-09-04T08:10:28 < R2COM> its one off board
2013-09-04T08:10:53 < R2COM> so waste of extra 3$ or so
2013-09-04T08:11:18 < GargantuaSauce_> now that is an expensive ldo
2013-09-04T08:11:22 < dongs> ya lm1117 is like $0.30
2013-09-04T08:11:25 < R2COM> senators waste thousands on hookers, how come I not waste 3$ on toying around with LDO?
2013-09-04T08:11:26 < dongs> and works.
2013-09-04T08:11:33 < R2COM> go complain in another place ;)
2013-09-04T08:11:39 < R2COM> about your cash
2013-09-04T08:12:05 < dongs> senators getting aids doesn't affect me because I hate america anyway
2013-09-04T08:12:16 < dongs> spacex spending my paypal fees on useless shit does :)
2013-09-04T08:13:49 < R2COM> compared to amount of money I saved on different projects with right decision this is nothing
2013-09-04T08:13:57 < R2COM> so stop bitching :)
2013-09-04T08:14:45 < GargantuaSauce_> giving you a hard time was worth your $3 for me
2013-09-04T08:15:04 < R2COM> for sure
2013-09-04T08:18:06 < R2COM> a satan is looking at my board now
2013-09-04T08:18:13 < R2COM> one pin broke right in a middle
2013-09-04T08:18:17 < R2COM> that header pin
2013-09-04T08:18:26 < R2COM> got broken in the middle
2013-09-04T08:18:28 < R2COM> lol
2013-09-04T08:18:59 < dongs> trolling R2COM never gets old
2013-09-04T08:19:08 < R2COM> no I am serious
2013-09-04T08:19:22 < dongs> sometimes i even run trolling simulations to see what R2COM would reply
2013-09-04T08:28:52 < zippe> dongs, did you ever rip open the DJI ACE?
2013-09-04T08:29:08 < zippe> Or the A2? I'm curious what their platform is.

2013-09-04T08:29:37 < dongs> zippe, ACEONE? that was some old atmel samXX shit
2013-09-04T08:29:43 < dongs> A2M is too new I think
2013-09-04T08:29:49 < dongs> they just "announced": it
2013-09-04T08:29:51 < dongs> like last week.
2013-09-04T08:29:57 < dongs> apparently something like $1200 or someshit
2013-09-04T08:29:59 < R2COM> so..all the buffers and everything works fine now
2013-09-04T08:30:15 < dongs> and theres gonna be no stopping of fucktards who'll buy it in droves
2013-09-04T08:30:16 < dongs> lol
2013-09-04T08:30:35 < R2COM> what is that?
2013-09-04T08:30:36 < R2COM> A2M?
2013-09-04T08:30:38 < dongs> zippe: they seem to change procesors for every thing
2013-09-04T08:30:53 < dongs> sam -> lpc -> no idea whats in a2m
2013-09-04T08:30:56 < zippe> dongs: interesting… any recollection which SAM?
2013-09-04T08:31:04 < zippe> What was the lpc one?
2013-09-04T08:31:09 < dongs> R2COM: http://www.aerialtechnology.com/dji-a2m-multirotor-flight-controller/
2013-09-04T08:31:32 < dongs> lpc176x
2013-09-04T08:32:13 < dongs> uC/OS-II Idle
2013-09-04T08:32:21 < dongs> also they used pirated uC/OS
2013-09-04T08:32:37 < dongs> zippe: my notes seem to imply sam3u but im not so sure, and im too lazy to open the ida database
2013-09-04T08:32:42 < zippe> No surprises there. Which product was that?
2013-09-04T08:32:46 < zippe> Ah, heh. 8)
2013-09-04T08:32:46 < dongs> i had it matched w/memoery maps to some atmel sam
2013-09-04T08:33:31 < dongs> i think that *was* aceone, because therre was a bunch of servo/heli trelated garbage in fw
2013-09-04T08:33:48 < dongs> and with every new product using differnt hw/cpu i doubt they're sharing much
2013-09-04T08:33:53 < zippe> Ya
2013-09-04T08:34:08 < zippe> Mostly wondering if any of the platforms are interesting enough to hack open for a firmware transplant
2013-09-04T08:34:12 < dongs> nope
2013-09-04T08:34:20 < dongs> plus you can't get to anything useful on them
2013-09-04T08:34:26 < dongs> jtag/etc is disabled, not easily accessible etc.
2013-09-04T08:34:40 < zippe> Ah, and encrypted firmware I guess. Lamers.
2013-09-04T08:34:43 < dongs> yep
2013-09-04T08:35:20 < zippe> Anyone else building a not-suck controller with a decent inertial damper?
2013-09-04T08:35:33 < dongs> nope
2013-09-04T08:35:48 < dongs> also, there's some weird fpga thing in the imu on wookdong (and others)
2013-09-04T08:35:53 < dongs> i think its actel smartfusion or similar shite
2013-09-04T08:36:14 < dongs> no idea why the fuck its there, its not doing anything revolutionary
2013-09-04T08:36:43 < zippe> Lots of fast ADCs on the smartfusion
2013-09-04T08:37:08 < dongs> that could be a reason, but how much faster are we talking here?
2013-09-04T08:37:11 < zippe> You could build a pretty nice setup with some analog sensors and one of those
2013-09-04T08:37:16 < dongs> hokay.
2013-09-04T08:37:24 < dongs> well, thats what wookong cube is, its all analog
2013-09-04T08:37:38 < zippe> Well, it's not just the ADCs, you'd build a set of filter blocks behind it and it would just poop out nice clean vectors
2013-09-04T08:38:07 < zippe> Your FPGA design guy would leave at 3pm every day and go get shitfaced at the bar down the street, but you could make it work.
2013-09-04T08:38:44 < R2COM> heh
2013-09-04T08:38:54 < zippe> (I say this having had a bunch of RTL folks walk out of a meeting at 4 today and not even go back to their cubes before heading out drinking…0
2013-09-04T08:39:25 < dongs> fucking assholes know tehy can't be replaced.
2013-09-04T08:39:28 < dongs> so they do whatever they want
2013-09-04T08:39:52 < zippe> Apart from the cute Japanese engineer, who I heard on the phone telling her boyfriend to go home and get naked. 8)
2013-09-04T08:40:16 < dongs> zippe, whats with ST sensors on latest pixdong. did ST give you a deal if you use all-their solution?
2013-09-04T08:40:44 < zippe> dongs: Lorenz and his army of undergrads did a bunch of tests; the ST sensors sucked the least out of what we could get
2013-09-04T08:40:52 < dongs> cool
2013-09-04T08:41:16 < dongs> the new industrial invensense shit looks interesting but it'll be years before one could buy it.
2013-09-04T08:41:17 < zippe> It's murder getting the BoM down to the point where you can retail a thing like that for $200, as I'm sure you know.
2013-09-04T08:41:22 < R2COM> if the stuff is so slow maybe there is not much benefit in bringing fpga to this business
2013-09-04T08:41:39 < zippe> There's a ton of pack-ins, plus the case, stickers, etc. etc. etc.
2013-09-04T08:41:56 < zippe> Alan @ 3DR actually did a really nice job on the case.
2013-09-04T08:42:26 < zippe> I snuck a couple of goodies in
2013-09-04T08:42:32 < R2COM> so what was the point
2013-09-04T08:42:48 < R2COM> quality analog sensors + ADC + good filters implemented on fpga?
2013-09-04T08:42:53 < dongs> case is prety cool
2013-09-04T08:43:07 < zippe> There's an LTC piezo motor driver for the speaker… it'll drive 30V into 500nF so you should be able to play Ride of the Valkyries loud enough to get everyone's attention
2013-09-04T08:43:28 < zippe> R2COM: plus DMA sequencing, plus sensor compensation, that'd be my guess
2013-09-04T08:44:08 < dongs> < zippe> Lamers.
2013-09-04T08:44:08 < zippe> Sadly, the Osram RGB LED I spec'ed is being trouble to source.
2013-09-04T08:44:15 < dongs> zippy shows his age, noone in teh last decade says "lamers" :(
2013-09-04T08:44:30 < zippe> It was bright enough that you could see it through the body of an EasyStar in direct sunlight.
2013-09-04T08:44:39 < dongs> nice
2013-09-04T08:44:44 < dongs> through the case?
2013-09-04T08:44:51 < dongs> or was that one of the leds that was in the opening
2013-09-04T08:45:02 < zippe> There's a hole in the case, and a clear patch in the sticker over the hole.
2013-09-04T08:45:10 < zippe> Same for the other LEDs
2013-09-04T08:45:22 < zippe> I never tested with sticker + easystar - still don't have any stickers here.
2013-09-04T08:45:45 < zippe> Basic idea was to have something you could see outside
2013-09-04T08:45:53 < dongs> right.
2013-09-04T08:45:54 < zippe> There's a remote-mounted extension LED as well.
2013-09-04T08:46:28 < dongs> is this new hardware opensores yet? or are you waiting to make sure rctimer doesn't ruin your day
2013-09-04T08:46:42 < zippe> Should be releasing the schematics when they ship
2013-09-04T08:46:43 < R2COM> oh
2013-09-04T08:46:53 < zippe> Have RCT cloned the first one yet?
2013-09-04T08:46:55 < R2COM> remember I talked about header pin broken in half?
2013-09-04T08:47:10 < R2COM> it was actually pushed in
2013-09-04T08:47:14 < R2COM> and looked broken
2013-09-04T08:47:18 < R2COM> lol
2013-09-04T08:47:19 < dongs> no idea i think they only clone shit that actually sells/has a purpose, px4 was too early to be useful
2013-09-04T08:47:19 < zippe> The schematics, at least, should be posted when the boards ship.
2013-09-04T08:47:53 < zippe> Sources are available now in the PX4 repo; apart from some pin map changes and sensor drivers it's basically the same animal though.
2013-09-04T08:48:00 < dongs> right

2013-09-04T09:18:20 < R2COM> that reg needs two caps
2013-09-04T09:18:37 < R2COM> dongs would probably use electrolytic parts with that reg
2013-09-04T09:19:03 < Thorn> how is that thing supposed to dissipate heat?

2013-09-04T09:29:18 < Thorn> rumoured to be ancient.
2013-09-04T09:29:29 < R2COM> you gotta be kidding?
2013-09-04T09:29:38 < R2COM> so ancient that even now it cant be intercepted?
2013-09-04T09:30:08 < dongs> silego shit looks cool but i'd have to think what hte fuck i'd use it for
2013-09-04T09:30:48 < dongs> alkso i think we had a similar discussion like 2 years ago

2013-09-04T09:31:07 < R2COM> what discussion?
2013-09-04T09:31:15 < dongs> about what to use it for
2013-09-04T09:32:36 < R2COM> 10Khz adc
2013-09-04T09:33:04 < R2COM> not sure dude
2013-09-04T09:33:47 < R2COM> seems too specific product
2013-09-04T09:34:32 < R2COM> small amount of luts
2013-09-04T09:34:33 < dongs> probably pays for zippe's retirement
2013-09-04T09:36:45 < R2COM> so its for very specific task in which you needs all its features and nothing else
2013-09-04T09:36:52 < R2COM> then maybe having that shit is justified
2013-09-04T09:36:59 < R2COM> rather than CPLD+uC etc..
2013-09-04T09:39:04 < R2COM> they have some low power RTC

2013-09-04T09:39:19 < R2COM> with 20ppm
2013-09-04T09:39:31 < R2COM> and 2x2mm
2013-09-04T09:39:36 < R2COM> looks attractive!
2013-09-04T09:39:38 < zippe> If I remember my scuttlebutt correctly, the Silego stuff exists to avoid having a bunch of 8-pin Atmel parts in systems
2013-09-04T09:39:48 < zippe> because Atmel were on the shit list (along with microchip) forever
2013-09-04T09:40:10 < R2COM> now that RTC would be a nice thing then!
2013-09-04T09:40:32 < R2COM> this huge trash occupies half of tqfp64 space on PCB for 32KHz RTC
2013-09-04T09:40:34 < R2COM> on board
2013-09-04T09:40:47 < R2COM> silego RTC is only 2x2mm
2013-09-04T09:40:50 < R2COM> and 20ppm
2013-09-04T09:41:34 < R2COM> its just for now I'm not much attracted to parts which are not on digikey, unless I *really* need them..
2013-09-04T09:41:49 < zippe> screw my retirement; I'm saving for this: http://cgi.ebay.com/ebaymotors/1972-Porsche-914-6GT-/190896050523?pt=US_Cars_Trucks&hash=item2c724a915b#ht_500wt_1182

2013-09-04T09:50:39 < dongs> that looks like a shitheap
2013-09-04T09:50:49 < zippe> Which one?
2013-09-04T09:50:53 < dongs> both
2013-09-04T09:50:58 < dongs> :)
2013-09-04T09:51:07 < zippe> Hah, you funny man
2013-09-04T09:51:17 < zippe> The orange one is a 350ci smallblock
2013-09-04T09:51:46 < zippe> It's about as good as those conversions get.

2013-09-04T09:53:08 < zippe> No, that would be a truck.
2013-09-04T09:53:24 < R2COM> truck which can do 0-60MPH in 5 secs?
2013-09-04T09:53:28 < R2COM> sure :)

2013-09-04T09:59:38 < zippe> Nice '06 G55 for $60K
2013-09-04T09:59:51 < zippe> Apartment with parking space that it will fit… $4k/mo
2013-09-04T10:00:04 < R2COM> well
2013-09-04T10:00:10 < R2COM> so?
2013-09-04T10:00:35 < R2COM> I think you are kinda overinflating
2013-09-04T10:00:37 < zippe> Now, I fit three cars, two motorcycles and two bicycles, plus trash and a ton of quadrotors, drones, etc. in my garage and I'm not paying that much.
2013-09-04T10:00:38 < R2COM> why 4$k dude
2013-09-04T10:00:58 < zippe> Because a single-bedroom apartment with no parking in SF is currently over $3k
2013-09-04T10:01:34 < zippe> Average selling price for a single family home in the SF bay area is currently ~US$1M
2013-09-04T10:01:36 < R2COM> I heard it costs a lot in around area. not directly in SF
2013-09-04T10:01:37 < R2COM> ok
2013-09-04T10:01:52 < R2COM> but wages are higher too
2013-09-04T10:02:02 < R2COM> (depends for whom...)
2013-09-04T10:02:17 < R2COM> but in general they are

2013-09-04T13:25:20 < zyp> handle_out is a callback, it will be called by the usb stack whenever new data is available, and you have to call read() inside that callback
2013-09-04T13:25:42 < zyp> then it's up to you what you do with the data afterwards
2013-09-04T13:25:46 < Posterdati> ah ok, shall I test for data read?
2013-09-04T13:25:50 < karlp> zyp: yeah, looking at TI and SMSC/microchip
2013-09-04T13:26:07 < karlp> just trying to work out how much of it I need.
2013-09-04T13:26:27 < Posterdati> zyp: I mean for data ready
2013-09-04T13:27:13 < zyp> Posterdati, line 88 will register that instance as the handler for out endpoint 1

2013-09-04T13:27:43 < Posterdati> zyp: ok
2013-09-04T13:27:47 < zyp> whenever a packet arrives on endpoint 1, your handle_out will be called with ep=1
2013-09-04T13:28:17 < Posterdati> and it automatically bail it out?
2013-09-04T13:28:30 < zyp> and you have to read it inside handle_out, otherwise it will be thrown away to not clog up the RX FIFO
2013-09-04T13:33:58 < dongs> usb_dm.set_af(10);
2013-09-04T13:34:00 < dongs> lol.

2013-09-04T15:13:06 < zyp> guy wants to use hdmi as networking for a rpi cluster
2013-09-04T15:14:47 < zyp> «… the test is to see how much processing power you can have while maintaining a minimum electrical requirement. Mhz per Watt, Raspberry Pis are more cost effective; especially when idle they consume basically 0 power.»
2013-09-04T15:22:09 < Laurenceb_> cant you use the i2c on hdmi?
2013-09-04T15:22:16 < Laurenceb_> or does it even have that
2013-09-04T15:22:55 < Laurenceb_> yeah pins 15-17
2013-09-04T15:23:07 < Laurenceb_> and 13
2013-09-04T15:23:51 < zyp> «Staying optimistic....could all output go through HDMI to a host, and input come in on 100BaseT? Is there a Full-monoplex (lol, not duplex) mode for 100 Mb/s input only? or a 90 Mb/s in, 10 Mb/s out?»

2013-09-04T16:36:46 < Laurenceb_> i usually get a few a day atm
2013-09-04T16:37:49 < Laurenceb_> maybe i could change the cable
2013-09-04T16:38:11 < Laurenceb_> belden microphone cable is annoying - all the parts can slip against one another
2013-09-04T16:38:27 < Laurenceb_> so i glue the outer jacket, and the wires are ripped off the pcb instead
2013-09-04T16:40:29 < Laurenceb_> i guess potting everything in epoxy might work

2013-09-05T01:37:31 < Posterdati> hi
2013-09-05T01:37:53 < Posterdati> I'm facing a nasty problem on f107: enabling SPI1 disables SYSTICK interrupt :(
2013-09-05T01:39:23 < zyp> no, it does not, you're just doing something weird
2013-09-05T01:40:35 < Posterdati> ...
2013-09-05T01:40:37 < Posterdati> mmh no
2013-09-05T01:40:52 < Posterdati> it happens only with SPI1
2013-09-05T01:48:06 < Posterdati> damned volatile :)
2013-09-05T01:49:34 < emeb> d'oh!
2013-09-05T01:52:58 < Posterdati> no way
2013-09-05T01:53:04 < Posterdati> it wasn't that
2013-09-05T02:05:52 < dongs> oh hey look
2013-09-05T02:05:59 < dongs> fagboxarm got funded at the last minute.
2013-09-05T02:06:06 < dongs> now my domain investment is even more funny.
2013-09-05T02:06:59 < Laurenceb_> http://goatkcd.com/strips_sfw/1229.jpg
2013-09-05T02:07:06 < Laurenceb_> that domain?
2013-09-05T02:07:31 < dongs> haha that shit never gets odl
2013-09-05T02:07:33 < dongs> old
2013-09-05T02:07:44 < dongs> http://www.kickstarter.com/profile/magicaltux isnt this the buttcoin faggot?
2013-09-05T02:11:13 < Laurenceb_> omfg its an arm on a breakout board
2013-09-05T02:11:15 < Laurenceb_> amazing
2013-09-05T02:12:05 < dongs> but it has msc bootloader
2013-09-05T02:12:07 < dongs> !!1111
2013-09-05T02:12:10 < dongs> and 64k flash F103
2013-09-05T02:12:35 < englishman> from Japan? magicaltux=dongs????? conspiracy
2013-09-05T02:13:07 < Laurenceb_> wait wut
2013-09-05T02:13:18 < Laurenceb_> msc with no external memory?
2013-09-05T02:13:24 < Laurenceb_> ok thats fairly smart
2013-09-05T02:13:35 < dongs> except mbed did it like 9000 days ago
2013-09-05T02:13:42 < Laurenceb_> so anything you copy onto the device is written to flash
2013-09-05T02:13:45 < dongs> yeah.
2013-09-05T02:13:49 < Laurenceb_> what could possibly go wrong
2013-09-05T02:13:53 < dongs> of course.
2013-09-05T02:14:01 < Laurenceb_> not sure if my n00b users could handle this
2013-09-05T02:14:13 < Laurenceb_> might go back to copy onto sd card approach
2013-09-05T02:14:22 < Laurenceb_> then it can checksum the file and things first

2013-09-05T02:32:29 < emeb> interesting "SwiftNAP" FPGA design
2013-09-05T02:33:43 < emeb> wonder how that Maxim front-end chip compares to the SiGe/Skyworks one.
2013-09-05T02:34:18 < dongs> it seems it just clocks out bits.
2013-09-05T02:34:25 < dongs> i dont think there can be that much different?
2013-09-05T02:34:32 < emeb> probably no

2013-09-05T03:14:55 < emeb> you'll remember when it's least convenient

2013-09-05T03:17:42 < dongs> no.
2013-09-05T03:17:44 < dongs> i linked you to 30A.
2013-09-05T03:17:49 < dongs> you were asking about 12 or 20 or someshit.
2013-09-05T03:17:55 < talsit> yeah, 20A
2013-09-05T03:18:00 < dongs> right, 20A is there too.
2013-09-05T03:18:06 < dongs> in same category.
2013-09-05T03:18:09 < talsit> cool, yeah, i know about the HK ones, i just wanted something local/quicker
2013-09-05T03:18:12 < talsit> but thanks
2013-09-05T03:19:56 < Posterdati> strange
2013-09-05T03:20:53 < Posterdati> I created __enable_irq and __disable_irq as naked, that's trashed my stack only with SPI, because I call these functions inside rea a write to spi :)
2013-09-05T03:21:14 < Posterdati> read and write in spi device
2013-09-05T03:21:15 < Posterdati> :)
2013-09-05T03:21:17 < Posterdati> lol funny
2013-09-05T03:29:58 < talsit> dongs, got a quote from p-ban, doesn't seem that bad
2013-09-05T03:36:04 < talsit> also, dongs, do you know of a supplier of brush-on conformal in japan?
2013-09-05T03:45:43 < dongs> no, i'd probably order that shit from china/ebay if i needed it
2013-09-05T03:46:42 < Posterdati> zyp: seems that your usb stack works flawlessy
2013-09-05T03:47:06 < Posterdati> please is there anyone using an adxl345 in spi mode?
2013-09-05T03:47:13 < talsit> that was my suspicion

2013-09-05T09:07:50 < emeb_mac> looks like they've got their lowspeed USB running for a bootloader.

2013-09-05T09:09:20 < emeb_mac> cause the kids just love it!
2013-09-05T09:09:51  * emeb_mac makes KMFDM reference. no one gets it.
2013-09-05T09:10:01 < dongs> yeah sorry, rock music sucks.
2013-09-05T09:10:13 < dongs> emeb_mac: youre I2S pro right
2013-09-05T09:10:24 < emeb_mac> dongs: I do a lot of I2S
2013-09-05T09:10:28 < dongs> is it self-clocking, i mean, can i recover its clock without knowing it ahead of time?
2013-09-05T09:10:29 < R2COM> another tiny amateur board?
2013-09-05T09:10:34 < R2COM> great
2013-09-05T09:10:41 < dongs> or do i need ot know what its running at
2013-09-05T09:10:41 < R2COM> dongs buy 100 of them and use in your projects
2013-09-05T09:10:54 < emeb_mac> dongs: I2S has a bit clock in it.
2013-09-05T09:10:58 < emeb_mac> and a frame clock
2013-09-05T09:11:05 < dongs> like if I have I2S on some random board can I just patch into the wires and take it?
2013-09-05T09:11:14 < emeb_mac> ya
2013-09-05T09:11:22 < emeb_mac> some DACs can autoconfigure
2013-09-05T09:11:33 < emeb_mac> CS4344 does ferinstance
2013-09-05T09:12:13 < dongs> is tehre any single-chip shit to do I2S->SPDIF?
2013-09-05T09:12:29 < emeb_mac> should be - lemme check...
2013-09-05T09:13:11 < emeb_mac> http://www.cirrus.com/en/products/interfaces_and_sample_rate_converters.html
2013-09-05T09:13:25 < emeb_mac> various I2S / SPDIF there
2013-09-05T09:13:48 < dongs> it doesnt mention i2S so i presume they all have it?
2013-09-05T09:14:04 < emeb_mac> pretty much
2013-09-05T09:14:12 < dongs> OK
2013-09-05T09:14:25 < dongs> but I still need some minimal configuration on this shit looks like
2013-09-05T09:14:31 < dongs> via i2c/spi like junk
2013-09-05T09:14:35 < dongs> but thats ok
2013-09-05T09:14:35 < emeb_mac> right
2013-09-05T09:14:46 < dongs> and spdif i dont need any kinda driver or anything for it?
2013-09-05T09:14:57 < dongs> just hookup one of those socket shits w/led inside?
2013-09-05T09:15:18 < emeb_mac> that should work
2013-09-05T09:15:33 < emeb_mac> if you use the RCA-style SPDIF then you might need a line driver.
2013-09-05T09:16:09 < dongs> no, just optical
2013-09-05T09:16:27 < emeb_mac> should be fine.
2013-09-05T09:16:39 < emeb_mac> but looks like the 8406 has the SPDIF line driver in it.
2013-09-05T09:17:13 < dongs> 5V digital I/O
2013-09-05T09:17:20 < dongs> can be used with tarduino, perfect.
2013-09-05T09:17:38 < dongs> shit's even on digikey
2013-09-05T09:18:06 < dongs> jebus their "evaluation boards" on digikey are fucking rich
2013-09-05T09:18:17 < emeb_mac> $$ - typical
2013-09-05T09:18:24 < dongs> i thought maybe to save the waste of making a board and just get a cheap evalboard w/some random mcu and reporuse it
2013-09-05T09:18:29 < dongs> http://media.digikey.com/photos/Cirrus%20Logic%20Photos/CDB42L51.JPG
2013-09-05T09:18:33 < dongs> http://www.digikey.com/product-detail/en/CDB42L51/598-1005-ND/923125
2013-09-05T09:18:54 < emeb_mac> those parts have been around for ages
2013-09-05T09:19:07 < dongs> ya, i can tell by the ancient soic package.
2013-09-05T09:19:08 < emeb_mac> so the eval boards prolly use chips you can't get any more

2013-09-05T09:35:24 < dongs> soemtimes I dont want that if I want to start stepping the code right away for example
2013-09-05T09:35:24 < emeb_mac> kthx - will check
2013-09-05T09:35:46 < dongs> also there's a 'run to main()' option that might or might not be useful
2013-09-05T09:35:52 < dongs> otherwise debug starts from reset vector asm.
2013-09-05T09:35:54 < emeb_mac> ah - if you want to jump right into the debugger
2013-09-05T09:35:59 < dongs> ya
2013-09-05T09:36:21 < dongs> well, shit, im excited
2013-09-05T09:36:24 < dongs> this dongle works again
2013-09-05T09:36:29 < dongs> i should find the one that got trashed by update
2013-09-05T09:36:36 < dongs> i wonder where hte fuck i tossed it

2013-09-05T13:04:59 < dongs> yea
2013-09-05T13:05:55 < dongs> in SPI mode only tho
2013-09-05T13:10:46 < zyp> I've used it with I2C
2013-09-05T13:10:47 < Posterdati> dongs: how can I reset it?
2013-09-05T13:11:18 < Posterdati> zyp: the cdc part works well, now I have to send data over the hid out endpoint
2013-09-05T13:12:14 < dongs> Posterdati: you don't? i've never had to reset it.
2013-09-05T13:12:16 < Posterdati> zyp: I was able to hook a minicom to /dev/ttyACM0 and send a and b characters, with a it starts the adxl345 in measure mode, with b it stops the adxl345
2013-09-05T13:12:24 < zyp> http://cgit.jvnv.net/arcin/tree/main.cpp <- here's some HID stuff
2013-09-05T13:14:19 < Posterdati> dongs: when I'm using external interrupt, if the buffer overrun, the interrupt stops and I have to flush the adxl345 cache to restart DATAREADY interrupt, is there another way to clear the FIFO?
2013-09-05T13:15:04 < dongs> ive used fifo on it. just read it all out and done?
2013-09-05T13:15:11 < zyp> Posterdati, you can just put the hid interface along with the cdc interfaces in the same configuration descriptor, you just have to make sure you change the interface and endpoint numbers so they don't collide
2013-09-05T13:15:24 < dongs> i think theres also a mode to make it overwite on full
2013-09-05T13:15:38 < Posterdati> zyp: I did so
2013-09-05T13:15:49 < Posterdati> endpoint 2
2013-09-05T13:16:29 < Posterdati> now, adxl345 data is collected in two 512 bytes buffers
2013-09-05T13:16:56 < Posterdati> when a buffer is full, the other is collecting ata and I have to send the full buffer over usb hid

2013-09-05T13:26:39 < zyp> of course, it's required to use HID
2013-09-05T13:26:53 < zyp> what are you going to use HID for?
2013-09-05T13:27:25 < Posterdati> send out 4 16 bits data
2013-09-05T13:27:49 < zyp> but why HID?
2013-09-05T13:27:59 < Posterdati> 3 axys adxl345 readings + adc
2013-09-05T13:28:17 < Posterdati> zyp: what use then?
2013-09-05T13:28:33 < zyp> do you need to use anything in particular?
2013-09-05T13:28:51 < Posterdati> I'd like to have a serial connection as command console
2013-09-05T13:28:59 < Posterdati> and another channel to send out data
2013-09-05T13:29:41 < zyp> which OS are you using?
2013-09-05T13:30:27 < Posterdati> I have to work with linux/mac os and windows
2013-09-05T13:31:36 < zyp> in my quadrotor project I'm just using a pair of bulk endpoints as a command/response interface, and then I'm using an isochronous interface for streaming data
2013-09-05T13:31:39 < zyp> http://cgit.jvnv.net/suzumebachi/tree/main.cpp#n80
2013-09-05T13:32:10 < zyp> and then I use libusb to access it on the host
2013-09-05T13:32:28 < Posterdati> yes
2013-09-05T13:32:37 < Posterdati> libusb is easy
2013-09-05T13:32:48 < zyp> except on windows

2013-09-05T13:33:11 < zyp> anyway, HID sounds like a bad idea
2013-09-05T13:33:25 < zyp> how many packets per second are you hoping to send?
2013-09-05T13:34:00 < zyp> and what are your requirements for latency and jitter?
2013-09-05T13:35:04 < Posterdati> zyp: adxl345 is sending out data at 3200 Hz, I'm using its interrupt to get data out from its FIFO and store in the buffers
2013-09-05T13:36:35 < zyp> you can simply forget about sending 3200 packets per second
2013-09-05T13:36:51 < zyp> whatever you do, you're gonna have to combine multiple samples into each packet
2013-09-05T13:36:58 < Posterdati> exactly
2013-09-05T13:37:17 < Posterdati> that's why there are two buffers of 512 bytes each
2013-09-05T13:37:37 < Posterdati> one collecting, the other if full is flushed over usb
2013-09-05T13:38:32 < zyp> ok, fair enough, though, you'd better look at it as 16 buffers of 64 bytes
2013-09-05T13:38:47 < zyp> because max packet size for a bulk endpoint is 64 byte

2013-09-05T13:41:05 < Posterdati> yes
2013-09-05T13:41:35 < Posterdati> but 16 buffers are filled fair in small time
2013-09-05T13:42:13 < zyp> I'd just do it as a ringbuffer, and send every time there is enough data for a full packet
2013-09-05T13:42:34 < zyp> but that's the same really, just a different way of doing it
2013-09-05T13:43:19 < Posterdati> well using this kind of buffer I can flush the whole full buffer in one time, with ring buffer I have to pop every element for pushing
2013-09-05T13:43:25 < Posterdati> in usb buffer
2013-09-05T13:43:52 < zyp> no.
2013-09-05T13:44:18 < Posterdati> why no?
2013-09-05T13:44:53 < zyp> do you even know what a ringbuffer is?
2013-09-05T13:44:57 < Posterdati> yes
2013-09-05T13:45:05 < zyp> what is it?
2013-09-05T13:45:11 < dongs> its a buffer that rings
2013-09-05T13:45:14 < dongs> bananaphone
2013-09-05T13:45:17 < zyp> :D
2013-09-05T13:45:21 < Posterdati> I use a single buffer of fixed length
2013-09-05T13:45:26 < Posterdati> with two indices
2013-09-05T13:45:36 < Posterdati> one for back and one for front
2013-09-05T13:45:46 < Posterdati> inserting data in the front
2013-09-05T13:45:55 < Posterdati> and popping data from back
2013-09-05T13:45:58 < dongs> data in, aids out

2013-09-05T13:46:29 < zyp> Posterdati, so what is the problem you're talking about? what prevents you from reading 64 bytes at a time?
2013-09-05T13:46:30 < Posterdati> the two pointers increment until they are equal

2013-09-05T13:47:20 < Posterdati> zyp: the buffer you have to send haven't to be across the physical buffer end/start, I mean
2013-09-05T13:47:24 < dongs> great

2013-09-05T13:47:37 < dongs> who's paying for the fun?
2013-09-05T13:47:44 < zyp> Posterdati, I still don't see what the problem is
2013-09-05T13:47:59 < bairdy> The motorcycle I didn't buy because of being kicked out of Sydney..
2013-09-05T13:48:37 < bairdy> Using the money I'd saved up for the 3rd bike to pay for things.. Should last until about the end of the year.
2013-09-05T13:49:20 < dongs> cool
2013-09-05T13:49:23 < Posterdati> zyp: mmmh, do you mean you're sending the memory between end and start when start < end?
2013-09-05T13:49:27 < zyp> Posterdati, you always read 64 bytes at a time, so you make the buffer size 64*n, that way you will never have to wrap a read around the end of the buffer
2013-09-05T13:49:51 < Posterdati> ok
2013-09-05T13:50:12 < Posterdati> and write memory out only when you have end - start = 64 ???
2013-09-05T13:50:17 < zyp> yep
2013-09-05T13:50:26 < Posterdati> ah ok
2013-09-05T13:50:54 < Posterdati> so after that, start = start + 64 as if you really popped the data from ring buffer
2013-09-05T13:51:08 < zyp> yep
2013-09-05T13:51:39 < Posterdati> in that case did the wrap around end/start occur?
2013-09-05T13:52:00 < Posterdati> ah ok
2013-09-05T13:52:07 < Posterdati> that's no a problem
2013-09-05T13:52:09 < zyp> I'm doing the opposite in my audio code, there I put 192 bytes into the buffer at a time, while DMA reads out four bytes at a time
2013-09-05T13:52:13 < Posterdati> buffer if 64 * n
2013-09-05T13:53:07 < zyp> hmm
2013-09-05T13:53:08 < zyp> http://cgit.jvnv.net/laks_demo/tree/main.cpp?h=usb_audio#n211
2013-09-05T13:53:20 < Posterdati> zyp: please help me with report_desc
2013-09-05T13:53:28 < zyp> actually, in the audio code I'm handling wrap properly, because it might not always be 192 bytes
2013-09-05T13:53:46 < Posterdati> ah
2013-09-05T13:54:02 < zyp> you don't need report_desc if you're not doing HID
2013-09-05T13:54:08 < zyp> and doing HID for what you want to do is dumb
2013-09-05T13:54:28 < Posterdati> but it is simplier
2013-09-05T13:54:44 < Posterdati> and  I can use libusb :)
2013-09-05T13:55:08 < dongs> ...
2013-09-05T13:55:14 < dongs> libusb for hid???
2013-09-05T13:55:17 < Posterdati> ...
2013-09-05T13:55:26 < dongs> remind me to never buy your products
2013-09-05T13:55:34 < Posterdati> good
2013-09-05T13:55:42 <+dekar> dongs, libusb used to officially support HID
2013-09-05T13:55:43 < Posterdati> I spare a box
2013-09-05T13:56:04 < dongs> dekar: i dont give the slightest fuck what usb supports
2013-09-05T13:56:09 < dongs> libusb
2013-09-05T13:56:12 < dongs> its shit
2013-09-05T13:56:33 < dongs> and the only os that matters has  hid api
2013-09-05T13:56:44 < zyp> using HID and libusb sounds like a pointless combination
2013-09-05T13:57:01 < Posterdati> zyp: and what then?
2013-09-05T13:57:10 < dongs> if youre using trashusb just have a bulk endpoint
2013-09-05T13:57:12 < zyp> usually people that use HID for dumb stuff use that because they don't want to use libusb
2013-09-05T13:57:26 < Posterdati> ok
2013-09-05T13:57:47 < dongs> im using hid foor my 4 dp thing
2013-09-05T13:57:49 <+dekar> zyp, it used to wrap around the windows HID driver, so you were able to use libusb with HID devices without installing their driver.
2013-09-05T13:58:31 < zyp> dekar, and on OS X it's impossible to use libusb for HID at all
2013-09-05T13:58:46 <+dekar> zyp, it works, I've done it. Was ugly though :P
2013-09-05T13:58:51 < Posterdati> zyp: what do you suggest?
2013-09-05T13:59:00 <+dekar> Posterdati, hidapi
2013-09-05T13:59:13 < Posterdati> macos and linux too?
2013-09-05T13:59:21 <+dekar> zyp, I had to use a dummy kext matching my VID/PID
2013-09-05T13:59:23 < zyp> Posterdati, a plain vendor specific bulk endpoint
2013-09-05T13:59:36 < Posterdati> vendor specific?
2013-09-05T13:59:58 < zyp> yes, it means «no standard class»
2013-09-05T14:00:02 < dongs> fuck man.
2013-09-05T14:00:06 < dongs> read a book.
2013-09-05T14:00:09 < dongs> on usb
2013-09-05T14:00:11 < zyp> which means you can send what the fuck you want over it
2013-09-05T14:00:13 < dongs> go.
2013-09-05T14:00:23 < Posterdati> zyp: ok ...
2013-09-05T14:00:48 <+dekar> Posterdati, if you want to stay "driverless" on Windows, keep HID and use hidapi. That works without any hassle on OSX/Windows. For Linux you need to tweak permissions/udev in any case.
2013-09-05T14:01:07 < zyp> well, if you were using HID, you'd have to make a report descriptor saying you have a report with a bunch of vendor specific bytes, same shit
2013-09-05T14:01:25 < zyp> except more work and pointless hassle
2013-09-05T14:01:45 < zyp> also, HID is based on an interrupt endpoint
2013-09-05T14:01:54 < Posterdati> zyp: I don't know how to program a bulk endpoint
2013-09-05T14:01:55 < zyp> you really don't want to use that for high data rates
2013-09-05T14:02:19 <+dekar> If installing drivers on customer systems isn't an option, HID is pretty much the only option.
2013-09-05T14:02:31 < zyp> uh, the CDC ACM stuff is based on bulk endpoints, just with some fancy descriptors
2013-09-05T14:02:43 < Posterdati> ok
2013-09-05T14:03:12 < Posterdati> zyp: please how can I use report_desc stuffs?

2013-09-05T14:30:51 < Posterdati> zyp: how can I execute handle_out just to write in the endpoint?
2013-09-05T14:31:08 < zyp> handle_out has nothing to do with write, only read
2013-09-05T14:31:13 < zyp> you can write whenever you want to
2013-09-05T14:31:27 < zyp> (as long as the endpoint is ready to handle a write)
2013-09-05T14:33:03 < Posterdati> ok, so ep_ready test and then write()
2013-09-05T14:51:14 < Posterdati> zyp: I could use software interrupt triggered when one of the buffer is full and then flush it via usb

2013-09-05T15:24:07 < Posterdati> I'm trying to assemble swi r0
2013-09-05T15:24:16 < zyp> there's no swi instruction
2013-09-05T15:24:31 < zyp> you probably want svc
2013-09-05T15:24:42 < zyp> and it doesn't take any register arguments, only an 8-bit immediate
2013-09-05T15:24:45 < Posterdati> it assembled swi
2013-09-05T15:25:00 < Posterdati> swi is a thumb instruction
2013-09-05T15:25:14 < Posterdati> it should trigger a SVCall
2013-09-05T15:25:24 < zyp> swi is not a valid ARMv7 instruction, it's named svc now
2013-09-05T15:25:42 < Posterdati> svc immediate?
2013-09-05T15:26:16 < zyp> yep
2013-09-05T15:26:48 < zyp> http://cgit.jvnv.net/laks/tree/os/thread.h#n58 <- like my yield()
2013-09-05T15:27:09 < zyp> it will trigger the SVCall handler, which does a context switch
2013-09-05T15:27:15 < Posterdati> ah
2013-09-05T15:27:25 < Posterdati> I'm using SYSTICK and PendSV for that
2013-09-05T15:27:43 < zyp> I'm also planning to, I just haven't had time to rewrite it
2013-09-05T15:27:55 < Posterdati> anyway
2013-09-05T15:28:15 < zyp> either way, svc doesn't take any register arguments

2013-09-05T15:29:24 < Posterdati> I need to know wich event triggered the SVCall

2013-09-05T15:33:33 < zyp> I wouldn't bother using it at all
2013-09-05T15:33:49 < zyp> I'd just stuff the function number into r0 before calling svc
2013-09-05T15:34:09 < Posterdati> to look into stack it's a bit tricky and error prone
2013-09-05T15:34:24 < zyp> not stack, program code.
2013-09-05T15:34:40 < Posterdati> ...
2013-09-05T15:35:03 < Posterdati> it's better to store something in r0 and then execute swi

2013-09-05T17:05:35 < Wipster> afternoon all, of the top of peoples head the reference manual of the stm32f4 for clocking, the VCO input freq needs to be between 1-2Mhz with preference for 2 for jitter reduction, also that the output of the PLL must be between 192-432Mhz, however seems to inply that PLLN is only valid from 192 to 432, does the datasheet assume a 1Mhz input? or does the system not like a lower value in the reg
2013-09-05T17:06:53 < zyp> no, it implies that PLLN is valid from 96 to 432

2013-09-05T18:42:13 < ddrown> Wipster: no problem
2013-09-05T18:44:09 < Wipster> I had read that the PLL in the F4 suffers from a fair bit of jitter and as such you cant run a PHY in RMII using it for a refclk, well you can but errors abound and odd behaviour
2013-09-05T18:44:27 < ddrown> Wipster: I too have heard that
2013-09-05T18:45:00 < ddrown> not sure what the tolerance level of jitter is for RMII
2013-09-05T18:46:01 < zyp> that's ok, just put a dedicated oscillator next to the phy, then run refclk back from that

2013-09-05T22:49:40 < zyp> no
2013-09-05T22:49:57 < Posterdati> ok
2013-09-05T22:50:12 < zyp> svc is typically used as a gateway between thread mode and supervisor mode
2013-09-05T22:50:14 < Posterdati> so why it goes in HardFault
2013-09-05T22:50:20 < Posterdati> ?
2013-09-05T22:50:28 < zyp> because you're doing something wrong, as usual
2013-09-05T22:50:48 < Posterdati> it is not suffice to place svc 0 ?
2013-09-05T22:51:54 < zyp> sure, assuming that you've got a proper handler

2013-09-05T22:52:07 < Posterdati> yes, the handler is there
2013-09-05T22:52:18 < Posterdati> SVCall
2013-09-05T22:52:30 < zyp> that's what you believe
2013-09-05T22:52:32 < zyp> but is it really?
2013-09-05T22:52:38 < Posterdati> yes
2013-09-05T22:52:46 < Posterdati> I looked in the disassembly
2013-09-05T22:53:55 < zyp> also, note that if you do a svc from another interrupt handler, it will hardfault if the svc handler can't preempt the current handler
2013-09-05T22:54:32 < Posterdati> ah that's is
2013-09-05T22:55:30 < Posterdati> even an EXTI interrupt handler?

2013-09-05T22:57:10 < gxti> speaking of threads n shit, are there any stm32-friendly rtos out there that have a better answer for event handling than 'make a thread for everything'? it's annoying needing a full thread in chibios just to handle flinging small amounts of data around
2013-09-05T22:57:30 < gxti> like if i want to poll 2 uarts and a bunch of TCP sockets at the same time, chibios has no answer for that
2013-09-05T22:58:54 < gxti> it doesn't even seem to be possible using just the core to wait on multiple semaphores, if i'm reading it correctly, so i'd have to structure things so that all the interesting events go into the same queue on the sender side

2013-09-05T23:13:41 < Posterdati> zyp: even if I call svc from a task?

2013-09-05T23:14:55 < gxti> that was my first guess
2013-09-05T23:16:09 < BrainDamage> I read that as underground lab
2013-09-05T23:16:12 < Laurenceb_> http://www.youtube.com/watch?v=kIR55jqGcZI
2013-09-05T23:16:15 < Laurenceb_> seriously...
2013-09-05T23:16:16 < BrainDamage> which is probaby true too
2013-09-05T23:16:22 < zyp> gxti, I've been thinking about making a framework for something like that
2013-09-05T23:16:26 < Laurenceb_> yes it is underground
2013-09-05T23:19:54 < Posterdati> zyp: I understand now
2013-09-05T23:20:48 < Posterdati> zyp: SVCall have to be not preempted as you said, so I gave it Priority = 0x00 and set SYSTICK Priority to 0x01 and PendSV = 0x0f
2013-09-05T23:20:54 < Posterdati> ah you said
2013-09-05T23:20:58 < Posterdati> as you said
2013-09-05T23:21:23 < zyp> uh, you're missing the point
2013-09-05T23:21:29 < Posterdati> ?
2013-09-05T23:21:55 < zyp> you can't call svc from a handler of the same or higher priority group as SVCall
2013-09-05T23:22:03 < Posterdati> aah
2013-09-05T23:22:07 < zyp> all the other stuff doesn't matter.
2013-09-05T23:22:13 < Posterdati> ok
2013-09-05T23:22:40 < gxti> zyp: maybe it could be built using chibios primitives, but then maybe i'd be better off starting over from a permissively-licensed core like coos
2013-09-05T23:23:03 < Posterdati> so if SYSTICK Priority = 0 and SVCall Priority  = 0 result is an HardFault
2013-09-05T23:23:04 < gxti> it's not that i have a hard-onl for events over threads, it's just that threads are really expensive to do trivial shit when you only have 64k ram
2013-09-05T23:23:21 < zyp> don't let me tell you what to do, I'm only interested in my own stuff, which is probably not appropriate for your purpose anyway :)
2013-09-05T23:23:30 < gxti> just thinking out loud
2013-09-05T23:23:43 < gxti> i kind of wanted to get off chibios anyway due to license

2013-09-06T03:12:35 < dongs> the one i was blogging about before
2013-09-06T03:12:41 < dongs> spi junk
2013-09-06T03:12:45 < dongs> for video leevls
2013-09-06T03:17:36 < emeb> righty
2013-09-06T03:18:01 < emeb> lookout world - programmable overlay grayscale coming up
2013-09-06T03:24:37 < dongs> you wish
2013-09-06T03:24:44 < dongs> its on same bus as pixel out
2013-09-06T03:25:18 < dongs> at best I can do vertical gradations :)
2013-09-06T03:25:23 < emeb> so set once @ powerup & then you're stuck with it
2013-09-06T03:25:38 < dongs> well, if its same cpol/cpha i *could* clock out different brightness per line.
2013-09-06T03:25:50 < dongs> just for lulz.
2013-09-06T03:25:52 < emeb> right - reprogram during H retrace
2013-09-06T03:26:37 < emeb> wonder if you could do inverse video?
2013-09-06T03:26:44 < emeb> for highlighted lines of text
2013-09-06T03:26:59 < dongs> how? i can't invert the actual video signal, i can only switch it
2013-09-06T03:27:42 < emeb> yeah - only two states - external video or your overlay
2013-09-06T03:27:53 < emeb> I suppose you could do white vs black overlay
2013-09-06T03:28:19 < dongs> i ahve 4 switch inputs
2013-09-06T03:28:30 < dongs> so i have original/white/black/vid2
2013-09-06T03:28:58 < emeb> can you select any of the 4 per-pixel?
2013-09-06T03:29:23 < dongs> yes
2013-09-06T03:29:42 < emeb> you have 2 spi channels synchronized?
2013-09-06T03:29:45 < dongs> yeah
2013-09-06T03:29:49 < emeb> kewl
2013-09-06T03:30:01 < dongs> spi slave off a timer
2013-09-06T03:30:09 < dongs> clocking out w/miso
2013-09-06T03:30:13 < dongs> super hax.
2013-09-06T03:30:41 < emeb> abuse to amuse
2013-09-06T03:31:14 < dongs> but hey
2013-09-06T03:31:36 < dongs> the vid2 input i might end up not using
2013-09-06T03:31:43 < dongs> i wonder if i can use it to dosome weird effects
2013-09-06T03:31:53 < dongs> like original video + ??? = input #4
2013-09-06T03:32:09 < dongs> can i easily invert video?
2013-09-06T03:32:20 < emeb> sure
2013-09-06T03:32:24 < dongs> is it just matter of inverting voltage/ or does it get trickier than that
2013-09-06T03:32:52 < emeb> might need some kind of offset, but could be as simple as running it through a common emitter transistor.
2013-09-06T03:33:02 < dongs> thing is when its on input #4 i can't have overlay
2013-09-06T03:33:15 < dongs> well, unless this "inverted" video "is" the overlay.
2013-09-06T03:33:36 < emeb> got any spare timer pins?
2013-09-06T03:33:42 < dongs> sure
2013-09-06T03:34:11 < emeb> run timer through a little RC network, scale to video levels & use for vid4
2013-09-06T03:34:20 < emeb> makes interesting patterns as you change timer freq
2013-09-06T03:35:12 < emeb> or, could do PWM to set a third gray level
2013-09-06T03:35:27 < dongs> oOOooOOOoOooOOOoOOooo
2013-09-06T03:35:58 < emeb> for that matter could use PWM for all the gray levels...
2013-09-06T03:36:09 < emeb> forget spidac
2013-09-06T03:37:29 < dongs> hmm.
2013-09-06T03:37:36 < dongs> just need rc right
2013-09-06T03:37:41 < emeb> ya
2013-09-06T03:38:15 < dongs> thats certainly cheaper than dac.
2013-09-06T03:38:21 < emeb> what's input impedance of the video switch?
2013-09-06T03:38:29 < dongs> ADG804, lets see
2013-09-06T03:38:53 < dongs> doesnt say?
2013-09-06T03:39:15 < emeb> it's a pure switch so depends on input impedance of what it's driving...
2013-09-06T03:40:23 < emeb> that will determine your RC values.
2013-09-06T03:40:37 < emeb> spidac might be easier since it's got buffered output.
2013-09-06T03:41:10 < dongs> we'll see. i can certainly tap some PWM-capable channels (since I put 2 leds on pwm) and route it to input#4 for testing
2013-09-06T03:41:20 < dongs> on tv tuner shit I used rc for AGC signal
2013-09-06T03:41:34 < dongs> demod is pwm, tuner takes analog voltage for agc
2013-09-06T03:41:43 < emeb> ya
2013-09-06T03:41:55 < dongs> there it was just 10k/0.1uf type shit
2013-09-06T03:42:14 < dongs> pwm was in some khz range or someshit, i dint check
2013-09-06T03:42:37 < emeb> right
2013-09-06T03:42:53 < emeb> 10k/0.1uf has corner freq @ 160Hz

2013-09-06T03:44:15 < emeb> so 1kHz PWM is ~2 octaves up, will be attenuated ~12dB.

2013-09-06T03:45:21 < emeb> you'd probably want more attenuation than that - bigger cap, higher PWM freq.
2013-09-06T03:45:42 < dongs> what difference does it make?
2013-09-06T03:46:02 < emeb> you'd see variations in gray level @ PWM freq.

2013-09-06T03:46:43 < dongs> PayPal account required
2013-09-06T03:46:55 < dongs> i wonder if anyone would actually pay for that with paypal
2013-09-06T03:46:59 < emeb> Elon Musk's paypal acct.
2013-09-06T03:47:03 < dongs> Ya.
2013-09-06T03:47:49 < dongs> hokay. gonna go get shit done before the stuff shows up at noon.
2013-09-06T03:47:52 < dongs> bbl

2013-09-06T08:29:28 < dongs> oh man what the FUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUCK
2013-09-06T08:29:30 < dongs> just got digikey order
2013-09-06T08:29:37 < dongs> and they fucking put like 20 displayport connectors
2013-09-06T08:29:40 < dongs> into a bag
2013-09-06T08:29:45 < dongs> no tray nothing just loose in fucking bag
2013-09-06T08:29:54 < dongs> and of course half of them have the fucking connector pins bent
2013-09-06T08:30:02 < emeb_mac> that's not like them
2013-09-06T08:30:02 < dongs> this is like the third time they fucked it up
2013-09-06T08:30:10 < dongs> they even sent me replacements for the first 2!
2013-09-06T08:30:25 < dongs> ya crystal is the only shit that was reflowed
2013-09-06T08:30:46 < dongs> http://i.imgur.com/T6i8No8.jpg second shit looked like this
2013-09-06T08:30:49 < dongs> digikey
2013-09-06T08:30:57 < dongs> this one they didnt evn bother with plastic
2013-09-06T08:31:00 < dongs> or foam or wahtever
2013-09-06T08:31:02 < dongs> just threw the shit in a bag
2013-09-06T08:31:05 < dongs> god damn wtf
2013-09-06T08:31:33 < emeb_mac> jeeze - what's up with all the rubber bands
2013-09-06T08:31:42 < dongs> yeah. it was supposed to keep the shit lined up
2013-09-06T08:31:46 < dongs> didnt work very well
2013-09-06T08:31:46 < emeb_mac> dumb
2013-09-06T08:32:09 < emeb_mac> should have used 2 layers of foam with connectors sandwiched between
2013-09-06T08:33:25 < emeb_mac> but with those screw flanges on the front it's hard to figure out how to package those connectors
2013-09-06T08:33:43 < dongs> my 1st order tehy just cut out a tray piece w/them in it
2013-09-06T08:33:46 < dongs> thats hwo ive been storing them
2013-09-06T08:33:50 < dongs> I got like 25
2013-09-06T08:33:59 < dongs> but this time i got 23, i dont see why they couldnt do same tray trick
2013-09-06T08:34:06 < emeb_mac> ya - leave em in the trays
2013-09-06T08:34:40 < dongs> at least 10 of these are gonna be trash
2013-09-06T08:34:46 < dongs> and those connectors are impossible to bend back
2013-09-06T08:34:49 < dongs> they're springy
2013-09-06T08:34:53 < dongs> once you bend them they're fucking ruined
2013-09-06T08:34:59 < emeb_mac> time for the live chats
2013-09-06T08:35:12 < dongs> ill just email same chick who i sent pics to before of the first 2 fail orders

2013-09-06T12:05:26 < zyp> if I'm gonna do a new batch, I'll revise the design a bit first to fix a couple of fuckups, but I don't think I will make any changes that would affect assembly cost

2013-09-06T14:46:30 < Laurenceb> oh yeah the info is int here
2013-09-06T14:46:36 < Laurenceb> *in
2013-09-06T14:47:40 <+Steffanx> lol
2013-09-06T15:01:23 < dongs> fgt.
2013-09-06T15:03:33 < Laurenceb> has anyone run libjpeg on smt32?
2013-09-06T15:06:08 < jpa-> i think i saw someone run nanojpeg
2013-09-06T15:07:23 < jpa-> a slightly silly license though, allowing commercial usage as long as you don't charge for it ;)
2013-09-06T15:08:14 < Laurenceb> i wanted encode
2013-09-06T15:09:28 < jpa-> jpegant seems promising, though gpl
2013-09-06T15:09:52 < Laurenceb> cool, thanks
2013-09-06T15:10:07 < dongs> Laurenceb: are you trying to replace shitberryspie with stm32
2013-09-06T15:10:27 < Laurenceb> yes lolz
2013-09-06T15:10:39 < dongs> you will fale
2013-09-06T15:10:40 < Laurenceb> only issue is lack of ram
2013-09-06T15:10:45 < dongs> right.
2013-09-06T15:10:48 < dongs> just add psram
2013-09-06T15:10:51 < dongs> to fsmc
2013-09-06T15:10:52 < dongs> done.
2013-09-06T15:10:59 < dongs> instant 8niggabytes
2013-09-06T15:11:03 < Laurenceb> or reduce the resolution...
2013-09-06T15:11:20 < Laurenceb> they are sending crap res anyway
2013-09-06T15:12:26 < Laurenceb> but theres no L1 with camera interface
2013-09-06T15:12:28 < Laurenceb> annoying
2013-09-06T15:12:43 < Laurenceb> wonder if you could DMA from a GPIO
2013-09-06T15:13:20 < jpa-> yes
2013-09-06T15:13:32 < jpa-> only trouble is triggering it at proper times
2013-09-06T15:13:32 < Laurenceb> ill have to play around
2013-09-06T15:13:41 < Laurenceb> i have some omnivision modules
2013-09-06T15:13:53 < Laurenceb> yeah
2013-09-06T15:26:41 < dongs> sure you can
2013-09-06T15:26:50 < dongs> just trigger from pixel clock or something
2013-09-06T15:26:54 < dongs> thouh its problygonna be too fast
2013-09-06T15:26:55 < dongs> to be useful
2013-09-06T15:33:30 < Laurenceb> GIF would work
2013-09-06T15:33:44 < Laurenceb> with line based encoding
2013-09-06T15:34:57 < Laurenceb> or 16bit 128 × 96 from an omnivision sensor
2013-09-06T15:35:00 < dongs> hm spi is locking up waiting for dicks
2013-09-06T15:35:23 < jpa-> Laurenceb: you only need to keep 8 lines in RAM anyway if you encode JPEG fast enough
2013-09-06T15:35:31 < Laurenceb> if
2013-09-06T15:35:46 < Laurenceb> i guess it might just work if the omnivision is clocked down
2013-09-06T15:35:47 < jpa-> make it fast enough.. give up on some accuracy in the DCTs
2013-09-06T15:41:12 < Laurenceb> looks like 500Khz PCLK is possible
2013-09-06T15:41:40 < dongs> hm RXNE on SPI never becomes set.
2013-09-06T15:41:42 < dongs> why?
2013-09-06T15:42:10 < Laurenceb> so with stm32l1 at 32mhz, 128 cycles/pixel
2013-09-06T15:42:19 < dongs> why oyu have to use L
2013-09-06T15:42:23 < dongs> just use f4discovery
2013-09-06T15:42:31 < Laurenceb> for low power
2013-09-06T15:42:35 < jpa-> dongs: did you transmit anything? :)
2013-09-06T15:42:35 < dongs> who cares
2013-09-06T15:42:39 < dongs> you flew a fucking hypeberry
2013-09-06T15:42:40 < dongs> jpa-: yeah
2013-09-06T15:42:41 < Laurenceb> and 1.8v operation
2013-09-06T15:42:52 < Laurenceb> i didnt
2013-09-06T15:42:54 < dongs> Laurenceb: 98% efficient DC/DC stuff is cheap
2013-09-06T15:42:59 < Laurenceb> im thinking of doing it properly
2013-09-06T15:43:07 < dongs> jpa-: same code works on another shit.
2013-09-06T15:43:13 < dongs> all clocks are on etc.
2013-09-06T15:43:15 < dongs> hm
2013-09-06T15:43:25 < Laurenceb> http://leobodnar.com/balloons/B-12/Pages/3.html
2013-09-06T15:43:27 < jpa-> Laurenceb: running a STM32F4 for a small amount of time may be more efficient than running STM32L1 all the time
2013-09-06T15:43:28 < Laurenceb> with a camera
2013-09-06T15:43:46 < Laurenceb> i ideally need eeprom
2013-09-06T15:43:49 < Laurenceb> and opamps
2013-09-06T15:43:59 < karlp> how much eeprom?
2013-09-06T15:44:03 < dongs> -> F3
2013-09-06T15:44:04 < jpa-> the opamps are a lie
2013-09-06T15:44:05 < Laurenceb> 4KB
2013-09-06T15:44:12 < karlp> I mean, that's why we're using an L1, not for any low pwoer
2013-09-06T15:44:29 < jpa-> i'm using L1 because it is lovely :)
2013-09-06T15:44:55 < dongs> wtf.
2013-09-06T15:45:24 < jpa-> Laurenceb: i wonder how many clocks per pixel doing integer 8x8 DCT on a STM32L1 would take
2013-09-06T15:45:34 < Laurenceb> im trying to work it out
2013-09-06T15:45:42 < Laurenceb> http://e2e.ti.com/support/microcontrollers/stellaris_arm/f/471/t/119230.aspx
2013-09-06T15:46:46 < zyp> dongs, you're doing F3 now?
2013-09-06T15:46:56 < zyp> probably same FIFO bullshit issues I ran into
2013-09-06T15:47:41 < zyp> I think it defaults to only set RXNE when you have two bytes in fifo, so after sending only one it won't be set
2013-09-06T15:49:09 < jpa-> Laurenceb: you could also take some shortcuts, like instead of doing the full transform at once, only calculate the terms until they drop below the quantization limit.. that way constant-colored blocks would be skipped quickly
2013-09-06T15:49:17 < dongs> zyp, the QF shit?
2013-09-06T15:49:27 < dongs> SPI_RxFIFOThresholdConfig(SPI1, SPI_RxFIFOThreshold_QF); i ahve this.
2013-09-06T15:49:34 < zyp> hmm, probably
2013-09-06T15:49:56 < zyp> I don't remember what it was called, but I had to set some flag in CR2, I assume it's the same
2013-09-06T15:50:10 < Laurenceb> hmm benchmarks are about 2K cycles/pixel on M3
2013-09-06T15:50:24 < Laurenceb> and 750/pixel on A8
2013-09-06T15:50:31 < Laurenceb> this is not good
2013-09-06T15:50:58 < jpa-> Laurenceb: but it seems you are ready to sacrifice some image quality, right?
2013-09-06T15:51:05 < Laurenceb> yes
2013-09-06T15:51:25 < jpa-> i bet you can get it much faster than a "full" jpeg encoder then
2013-09-06T15:51:30 < dongs> SPIx->CR2 &= (uint16_t)~((uint16_t)SPI_CR2_FRXTH);
2013-09-06T15:51:31 < Laurenceb> hmm yeah
2013-09-06T15:51:32 < dongs> this
2013-09-06T15:51:36 < dongs> SPIx->CR2 |= SPI_RxFIFOThreshold;
2013-09-06T15:51:53 < zyp> ah, FRXTH yes
2013-09-06T15:52:00 < dongs> hmpf
2013-09-06T15:52:08 < dongs> nothing goes over the bus either.
2013-09-06T15:52:14 < dongs> AF is corect.
2013-09-06T15:52:18 < zyp> it doesn't start sending?
2013-09-06T15:52:20 < jpa-> even just doing one horizontal 8-item transform and one vertical 8-item transform might give sufficient results.. it throws away a bunch of data, but atleast preserves the location of edges
2013-09-06T15:52:21 < dongs> yeah
2013-09-06T15:52:48 < zyp> did you enable software slave control and force it to always master?
2013-09-06T15:52:54 < dongs> ya.
2013-09-06T15:53:05 < zyp> strange
2013-09-06T15:53:12 < dongs> http://bcas.tv/paste/results/ZRX4fn36.html
2013-09-06T15:53:22 < dongs> im sure i missed somethin mega dum.
2013-09-06T15:53:27 < zyp> esp. since you said it works on other stuff, since FRXTH is the main change on F3
2013-09-06T15:53:38 < dongs> it even works on ANOTHER f3.
2013-09-06T15:53:44 < dongs> which is why im kinda puzled.
2013-09-06T15:53:54 < zyp> umm
2013-09-06T15:53:54 < dongs> unless my  AF is fucked or something
2013-09-06T15:54:05 < zyp> RCC_APB2PeriphResetCmd(RCC_APB2Periph_SPI1, ENABLE); <- does this also clear the reset bit?
2013-09-06T15:54:24 < dongs> doesnt matter, it didnt work owithout it there either
2013-09-06T15:54:28 < dongs> i think reset autoclears
2013-09-06T15:55:00 < dongs> working code has that line too.

2013-09-06T15:55:45 < dongs> my spiTransfer() are using SPI2.
2013-09-06T15:55:49 < dongs> the shit that checks.

2013-09-06T15:58:10 < dongs> well, SPI dac doesnt like that
2013-09-06T15:59:26 < Laurenceb> hmm looks like using optimised code and the omnivision clocked down to give 500khz pclk it might just work
2013-09-06T16:00:08 < Laurenceb> blackfin is 90clks/pixel
2013-09-06T16:00:38 < Laurenceb> using nanojpeg lib
2013-09-06T16:01:44 < dongs> data goes in.
2013-09-06T16:03:27 < dongs> should be configured with its CPOL bit as a zero and its CPHA bit as a one.
2013-09-06T16:03:40 < dongs> MOSI output to be valid on the falling edge of SCLK
2013-09-06T16:04:34 < jpa-> Laurenceb: libjpeg on x64 seems to take 117 instructions per pixel (using the "fast integer dct" algorithm)
2013-09-06T16:05:01 < Laurenceb> interesting, thanks for the info
2013-09-06T16:05:16 < Laurenceb> this would be for SSDV over HAM radio
2013-09-06T16:05:26 < Laurenceb> so only the DCT is needed
2013-09-06T16:05:47 < Laurenceb> well - theres some upper level stuff but that can be done later
2013-09-06T16:06:14 < Laurenceb> image sensor -> dma buffer -> line based DCM and some compression stuff.. -> buffer
2013-09-06T16:06:38 < Laurenceb> then the buffer is much smaller and is rebroadcast with FEC and stuff later
2013-09-06T16:06:51 < Laurenceb> only the DCM and compression needs to be fast
2013-09-06T16:07:34 < jpa-> i guess libjpeg would actually fit and work pretty well on STM32.. less than 50kB if you compile in only one algorithm
2013-09-06T16:07:46 < Laurenceb> apparently is very inefficient
2013-09-06T16:07:48 < dongs> hm chipselects arent working
2013-09-06T16:08:01 < Laurenceb> blockfin guy says he got 3x speedup very easily
2013-09-06T16:08:06 < Laurenceb> *blackfin
2013-09-06T16:08:23 < jpa-> sure.. as soon as you start optimizing for specific processor there are bound to be speedups
2013-09-06T16:08:24 < Laurenceb> hes benchmarking 90clk/pixel for full encode

2013-09-06T16:31:56 < dongs> huh no
2013-09-06T16:31:58 < dongs> this is dac output.
2013-09-06T16:32:11 < dongs> im just trying to do a 0..255 curve
2013-09-06T16:32:13 < zyp> supposed to be a linear ramp?
2013-09-06T16:32:15 < zyp> right
2013-09-06T16:32:16 < dongs> yeah
2013-09-06T16:32:30 < dongs> it looks like bits are off or soemthign
2013-09-06T16:32:38 < dongs> pattern looks like failed binary
2013-09-06T16:32:41 < jpa-> maybe you have MSB and LSB wrong way around or something?
2013-09-06T16:32:42 < zyp> yeah
2013-09-06T16:33:03 < dongs> the shit in comment is the msb/lsb
2013-09-06T16:33:05 < dongs> D7..D0
2013-09-06T16:33:10 < dongs> should be correct, no?
2013-09-06T16:33:34 < jpa-> if the comment is accurate and that on the wire you actually put them out in the order that the chip expects
2013-09-06T16:35:27 < dongs> if the order was wrong
2013-09-06T16:35:30 < dongs> i wouldnt even be getting output
2013-09-06T16:35:37 < dongs> since first couple bits define which dac + power mode
2013-09-06T16:35:55 < jpa-> if you count 0..255, you'll eventually hit the right bits :P
2013-09-06T16:36:08 < dongs> not with a graph like that
2013-09-06T16:36:41 < jpa-> well if the bytes were swapped, you'd be going through the combinations every 16 cycles, which could explain the noise
2013-09-06T16:36:53 < jpa-> but yeah, it is just one possibility
2013-09-06T16:37:44 < dongs> swapping nibbles results in worse stuff.

2013-09-06T16:41:13 < dongs> The data format is straight binary (MSB first, LSB last), with all 0's corresponding to an output of 0V and all 1's
2013-09-06T16:41:16 < dongs> corresponding to a full-scale output of VREFIN - 1 LSB

2013-09-06T16:42:45 < dongs> fuck this makes no sense
2013-09-06T16:43:09 < dongs> addressing is correct. 2nd DAC is 0V. only 1st one is changing.
2013-09-06T16:43:17 < dongs> so its the data order...
2013-09-06T16:43:40 < jpa-> dongs: scope the data lines together with DAC output?
2013-09-06T16:44:21 < dongs> why? spi data is correct.
2013-09-06T16:44:27 < dongs> i got spi flash on tehre and I can send it jedec ID command
2013-09-06T16:44:34 < dongs> and it replies

2013-09-06T16:44:47 < zyp> which dac is that?

2013-09-06T16:49:22 < dongs> and SPI flash doesnt like cpol_low.
2013-09-06T16:49:23 < dongs> LAME.
2013-09-06T16:49:51 < zyp> right, so you just messed up cpol/cpha
2013-09-06T16:49:59 < dongs> not "messed up"
2013-09-06T16:50:03 < dongs> the shit needs it non-standard.
2013-09-06T16:50:06 < dongs> :(
2013-09-06T16:50:08 < zyp> set it wrong = messed up
2013-09-06T16:50:20 < zyp> «non-standard»
2013-09-06T16:50:42 < zyp> the problem with SPI is that there is no fixed standard, so people do all sorts of different stuff
2013-09-06T16:51:01 < jpa-> the great thing about standards etc.
2013-09-06T16:51:37 < zyp> so far the dumbest I've seen is the TI NFC chips, that use a different CPHA setting for sending and receiving
2013-09-06T16:53:54 < dongs> is cpol hardto change?
2013-09-06T16:53:58 < dongs> d oi need to reset spi peripheral for it?

2013-09-06T16:56:31 < jpa-> ended up doing a dummy transfer after the change
2013-09-06T16:56:43 < jpa-> dongs: that is not linear ramp! :(
2013-09-06T16:56:58 < dongs> no shit. after i confirmed linear I changed it to this

2013-09-06T16:57:21 < dongs> wazzat?
2013-09-06T16:57:43 < zyp> that's what happens when you change CPHA without disabling
2013-09-06T16:57:56 < dongs> that glitch?
2013-09-06T16:57:58 < dongs> on mosi?

2013-09-06T16:58:23 < dongs> ok, so nothing bad happens.
2013-09-06T16:58:24 < dongs> great.
2013-09-06T16:58:31 < zyp> no, the extra bits
2013-09-06T16:58:32 < dongs> looks like i could still do per-line grayscale then :D
2013-09-06T16:58:45 < dongs> ? what extra bits
2013-09-06T16:58:50 < dongs> thats just logic being dumb, no?
2013-09-06T16:59:35 < zyp> that was supposed to be a two byte transfer, hardware decides to throw in four extra bits somewhere
2013-09-06T17:00:13 < zyp> likely the middle four
2013-09-06T17:01:01 < jpa-> for me it was in the beginning
2013-09-06T17:01:08 < zyp> ah, that might be
2013-09-06T17:01:14 < zyp> first four bytes
2013-09-06T17:01:16 < zyp> bits*
2013-09-06T17:01:38 < zyp> because it didn't happen on the first transfer after reset, only following ones
2013-09-06T17:01:44 < jpa-> but i think i actually had missing bits
2013-09-06T17:01:53 < jpa-> 2013-02.log:2013-02-22T17:15:06 < jpa-> wtf is going on with my spi.. after changing the clock speed, the first transfer contains 11 bit instead of 2x8 bits
2013-09-06T17:02:03 < dongs> uh huh
2013-09-06T17:02:12 < dongs> is this awaiting me, too ?:)

2013-09-06T17:47:22 < dongs> Prior to changing the CPOL/CPHA bits the SPI must be disabled by resetting the SPE bit.
2013-09-06T17:47:25 < dongs> FUCK Y OU.
2013-09-06T17:47:35 < jpa-> just like zyp said
2013-09-06T17:47:44 < zyp> exactly my point
2013-09-06T17:47:47 < jpa-> but it is just a bit, don't make such a big deal about it
2013-09-06T17:47:52 < dongs> um
2013-09-06T17:48:01 < dongs> disabling means, i have to reinit peripheral again
2013-09-06T17:48:02 < zyp> that's what I didn't do which caused it to fuck up
2013-09-06T17:48:04 < dongs> not just flip one bit
2013-09-06T17:48:06 < jpa-> dongs: nope
2013-09-06T17:48:09 < zyp> nah
2013-09-06T17:48:11 < dongs> nope?
2013-09-06T17:48:13 < jpa-> dongs: the peripheral forgets nothing
2013-09-06T17:48:21 < jpa-> it is just disabled for a while
2013-09-06T17:48:25 < zyp> you just clear the SPE bit in CR1, change CPOL/CPHA, then set SPE bit again

2013-09-06T20:46:50 < jpa-> hmm.. just installed jenkins, seems pretty nice
2013-09-06T20:47:15 < jpa-> even though i'm mostly using it as a glorified cron
2013-09-06T20:47:36 < karlp> jenkins is pretty nice :)
2013-09-06T20:48:13 < karlp> cron doesn't give you any of the long term graphing of status that jenkins will do for free
2013-09-06T20:48:20 < jpa-> yep
2013-09-06T20:48:35 < karlp> I've got it running "check" unit tests on c code too, which is nice,
2013-09-06T20:48:52 < karlp> haven't got code coverage for C yet though, need more people to write tests first
2013-09-06T20:50:00 < emeb> at least they didn't call it Jeeves.
2013-09-06T20:50:07 < jpa-> hmm yeah.. graphing code coverage over builds would be cool
2013-09-06T20:50:35 < karlp> yeah, we get that for our python code, and I used to get it for java at an old job, but for now I just get unit test volume and results for C
2013-09-06T20:51:26 < jpa-> i already have a makefile rule that nicely gives code coverage, so should be pretty easy to do
2013-09-06T20:51:29 < karlp> oh yeah, we have it running "busted" on lua code for tests too.
2013-09-06T20:51:30 < BrainDamage> so it's like buildbot on steroids?
2013-09-06T20:51:44 < karlp> or buildbot without all the nonsense
2013-09-06T20:52:57 < gxti> buildbot has rather a lot of nonsense

2013-09-07T11:32:47 < Alexer> turns out, my arbitrarily chosen TRDT value was wrong
2013-09-07T11:33:42 < Alexer> anybody have any idea how you're supposed to calculate it? the docs are less than clear in that regard...
2013-09-07T11:34:44 < Alexer> they say something like "TRDT = 4x AHB clock + 1 PHY clock"

2013-09-07T11:36:35 < Alexer> but I don't understand what are those relative to
2013-09-07T11:37:55 -!- zippe [~Adium@173.11.99.161] has quit [Quit: Leaving.]
2013-09-07T11:38:07 < Alexer> there are a few examples:
2013-09-07T11:38:08 < Alexer> 1. if AHB clock = 72 MHz (PHY Clock is 48), the TRDT is set to 9.
2013-09-07T11:38:08 < Alexer> 2. if AHB clock = 48 MHz (PHY Clock is 48), the TRDT is set to 5.
2013-09-07T11:39:33 < Alexer> and from looking at that, I assumed it's calculated relative to PHY clock (rounding up)
2013-09-07T11:40:41 < Alexer> so 72/48=1.5 is rounded to 2 and the equation becomes TRDT = 4*2+1 = 9, which would agree with the examples
2013-09-07T11:42:12 < Alexer> so I assumed when AHB clock is slower than PHY clock, you just round it up to 1, giving TRDT=5, which obviously wasn't a good idea
2013-09-07T11:44:42 < Alexer> so... my next idea would be relative to the slower clock, like if AHB=16 and PHY=48 => TRDT=4*1+1*3=7, but that doesn't work either
2013-09-07T11:44:55 < Alexer> TRDT=9 seems to work, but I have no idea why
2013-09-07T11:46:09 < Alexer> so... if anyone knows anything about calculating TRDT, I'm all ears :P

2013-09-07T13:21:37 < zyp> hang on, let me look it up
2013-09-07T13:25:43 < zyp> http://tom-itx.dyndns.org:81/~tom-itx/irc/logs/%23%23stm32/2013-03-14.html#15:19:16
2013-09-07T13:25:43 < dongs> http://www.segger.com/bitmap-converter.html yesss
2013-09-07T13:27:53 < zyp> Alexer, as I understand it, setting TRDT too low will fuck up transmission because you get a race condition, transmitting before all the data arrives
2013-09-07T13:29:04 < zyp> setting TRDT higher is fine from a device perspective, but you may risk that the reply from your device arrives too late at the host to be in spec if there are lots of hubs and long cables in between

2013-09-07T13:59:21 < Posterdati> zyp: I created this device --> http://pastebin.com/8q2wzujX
2013-09-07T13:59:44 < dongs> lunix device
2013-09-07T14:06:04 < zyp> Posterdati, you got the direction on the HID endpoint wrong
2013-09-07T14:06:22 < Posterdati> ah
2013-09-07T14:06:34 < Posterdati> it is an output
2013-09-07T14:06:50 < zyp> also, note that you've already used 0x82 in the control interface, so you can't use that for HID too
2013-09-07T14:07:05 < Posterdati> 0x82 = 0x02?
2013-09-07T14:07:09 < zyp> no
2013-09-07T14:07:21 < zyp> 0x02 is OUT 2, and 0x82 is IN 2
2013-09-07T14:07:35 < zyp> having both is fine, but you can only have one of each
2013-09-07T14:07:59 < zyp> and you want an IN interface for your HID device
2013-09-07T14:08:04 < Posterdati> no
2013-09-07T14:08:07 < Posterdati> an out interface
2013-09-07T14:08:24 < Posterdati> data should come out from that endpoint
2013-09-07T14:08:44 < zyp> all HID interfaces are required by spec to have an IN endpoint
2013-09-07T14:08:57 < Posterdati> ah
2013-09-07T14:09:05 < Posterdati> so I need to add an in too?
2013-09-07T14:09:09 < zyp> yes
2013-09-07T14:09:23 < Posterdati> but it will be unused
2013-09-07T14:09:41 < zyp> OUT is optional, if you don't have an OUT interface, OUT reports will be sent via the SET_REPORT control request instead

2013-09-07T14:10:03 < zyp> also, are you really sure that you understand IN and OUT correctly?
2013-09-07T14:10:12 < Posterdati> mmmmh
2013-09-07T14:10:29 < Posterdati> out = coming from usb to pc
2013-09-07T14:10:37 < zyp> no, that's wrong
2013-09-07T14:10:40 < zyp> that's IN
2013-09-07T14:10:56 < Posterdati> even from micro point of view?
2013-09-07T14:11:11 < zyp> yes, IN and OUT are always seen from the host perspective
2013-09-07T14:11:28 < Posterdati> ah my micro is a device
2013-09-07T14:11:33 < Posterdati> not an host
2013-09-07T14:11:35 < zyp> so IN always means «in to the host»
2013-09-07T14:12:01 < zyp> so for data you want to send from your device, IN is correct
2013-09-07T14:12:51 < Posterdati> ok
2013-09-07T14:13:08 < zyp> just change 0x02 to 0x83 and you'll get what you want
2013-09-07T14:13:19 < zyp> also, you have the type wrong
2013-09-07T14:13:26 < Posterdati> ah
2013-09-07T14:13:27 < zyp> it has to be an interrupt endpoint, not bulk
2013-09-07T14:13:35 < Posterdati> so IN enpoints has got >= 0x81
2013-09-07T14:13:44 < zyp> so the second parameter should be 0x03
2013-09-07T14:14:02 < Posterdati> endpoint_desc(0x83, 0x03, 64, 0)
2013-09-07T14:14:03 < zyp> yes, the upper bit (0x80) sets direction
2013-09-07T14:14:25 < zyp> hmm, the last parameter is the poll interval, it should be nonzero for interrupt endpoints
2013-09-07T14:14:31 < zyp> you probably want it to be 1
2013-09-07T14:14:39 < Posterdati> ok
2013-09-07T14:14:42 < zyp> which means «poll every frame»
2013-09-07T14:14:55 < zyp> i.e. as often as possible
2013-09-07T14:15:09 < Posterdati> this end point will be activated on buffer full
2013-09-07T14:15:28 < Posterdati> data will be pushed from buffer to endpoint using usb.write
2013-09-07T14:15:54 < Posterdati> is that correct?
2013-09-07T14:18:02 < zyp> yep
2013-09-07T14:18:18 < Posterdati> ok thanks
2013-09-07T14:20:47 < Posterdati> are cdcs bulk
2013-09-07T14:21:53 < zyp> ACM data is bulk, ACM control is interrupt
2013-09-07T14:22:21 < Posterdati> ok
2013-09-07T14:23:19 < Posterdati> what is the configurartion number?
2013-09-07T14:24:25 < Posterdati> for cdc data is 1
2013-09-07T14:24:27 < Posterdati> ?
2013-09-07T14:34:39 < Alexer> zyp, ah, thanks! so basically, the examples are wrong, and the comment saying that on higher frequencies the TRDT can be smaller is true
2013-09-07T14:35:10 < zyp> yep
2013-09-07T14:35:33 < Alexer> though I still don't get how the correct value for TRDT is calculated (except by trial and error :P)
2013-09-07T14:36:47 < Alexer> I mean, you said that even TRDT=1 worked with 168MHz, right?
2013-09-07T14:37:19 < zyp> even if it works in a limited test, it doesn't mean it's correct
2013-09-07T14:37:22 < zyp> :p
2013-09-07T14:37:46 < karlp> zyp: you have a usb hub with individual switches right? is it one from dx or something you picked up in jp?
2013-09-07T14:37:46 < Alexer> ah, that's true too :P
2013-09-07T14:38:07 < zyp> karlp, the latter
2013-09-07T14:38:20 < karlp> looking through dx now, there's .....lots.

2013-09-07T14:38:32 < zyp> I think I have six of them now
2013-09-07T14:39:31 < zyp> bought the wrong kind (bus powered) last time I were in jp, so I got a friend that went there this summer to pick up a few more of the right kind

2013-09-07T21:28:31 < Thorn> A small crowd stood behind the vet who conducted an hour-long procedure
2013-09-07T21:28:31 < Thorn> on a full-grown, anesthetized gray- and-white female cat in a clean,
2013-09-07T21:28:31 < Thorn> brightly lit animal hospital. The TSD chief audio engineer, seeing the fi rst
2013-09-07T21:28:31 < Thorn> incision and a trace of blood, asked to sit down. No other complications
2013-09-07T21:28:31 < Thorn> arose, and after the cat awakened, she was put into a recovery area for further
2013-09-07T21:28:31 < Thorn> testing. Technically the audio system worked, generating a viable audio
2013-09-07T21:28:32 < Thorn> signal.
2013-09-07T21:29:06 < Thorn> However, control of the cat’s movements, despite earlier training, proved so inconsistent that the operational utility became questionable.
2013-09-07T21:29:06 < Thorn> Over the next few weeks, Acoustic kitty was exercised against various operational scenarios, but the results failed to improve.

2013-09-08T02:26:33 < zyp> well, if you try doing something that the host doesn't understand, it will usually reset you
2013-09-08T02:26:49 < zyp> are you really using high speed with external phy?
2013-09-08T02:27:24 < Posterdati> I exchanged in with out on host side
2013-09-08T02:27:27 < zyp> if so, you should be aware that the rules for high speed are different, and my code assumes full speed in a lot of places

2013-09-08T02:30:12 < Posterdati> so if buffer 0 is full: yeld(0)
2013-09-08T02:30:20 < Posterdati> or yeld(1) for other buffer
2013-09-08T02:30:53 < Posterdati> after the svc is served buffer full is empty resetting pointer
2013-09-08T02:31:04 < Posterdati> to front and buffer state
2013-09-08T02:33:37 < Posterdati> in the same time other buffer is filling with precious sensor data

2013-09-08T14:18:52 < dongs> only works if I bridge video_2 to video_in
2013-09-08T14:18:54 < dongs> which means its hitting S 4
2013-09-08T14:18:56 < dongs> but how?
2013-09-08T14:18:59 < dongs> the lines are correct
2013-09-08T14:20:19 <+Steffanx> you're actually using this _s and Xs stuff...

2013-09-08T14:45:13 < Posterdati> dongs: did you ever used adxl345?
2013-09-08T14:45:24 < dongs> you asked me that be fore. no i dont know how to reset it.
2013-09-08T14:45:27 < dongs> i never had porblems with its fifo
2013-09-08T14:45:34 < Posterdati> yes
2013-09-08T14:45:36 < dongs> i would read it out when I had like ~7 samples in there.
2013-09-08T14:45:36 < Posterdati> I know
2013-09-08T14:45:58 < Posterdati> but I'm exeriencing that: if fifo overrun interrupt stay high
2013-09-08T14:46:11 < dongs> i didnt let it overrun
2013-09-08T14:46:39 < Posterdati> ok
2013-09-08T14:46:42 < Posterdati> thanks
2013-09-08T15:02:47 < dongs> crap.
2013-09-08T15:02:51 < dongs> i dont think these DMAs are running concurrently
2013-09-08T15:03:35 < jpa-> in what way concurrently? the memory bus can only make one transfer at a time, i think
2013-09-08T15:03:51 < jpa-> so the multiple channels get interleaved
2013-09-08T15:04:20 < dongs> yeah, eaxctly in that way

2013-09-08T15:36:17 < dongs> http://i.imgur.com/0W3VGSu.png
2013-09-08T15:36:19 < dongs> timing is exact.
2013-09-08T15:36:23 <+Steffanx> it's too precise
2013-09-08T15:36:31 < dongs> thats a possibility but i dont think so
2013-09-08T15:36:42 < dongs> um, hm.
2013-09-08T15:36:56 < dongs> i wonder if thats whats happening.
2013-09-08T15:38:04 < jpa-> or maybe you have other fails!
2013-09-08T15:39:12 < dongs> im gonna put black on cpol_high or something.
2013-09-08T15:39:16 < dongs> so its out of phase.
2013-09-08T15:40:32 < dongs> too much out of phase.
2013-09-08T15:47:54 < dongs> hm 1 pixel clock is like 460ns
2013-09-08T15:48:02 < dongs> this shit does break before make for 20ns
2013-09-08T15:53:38 < dongs> hm
2013-09-08T15:53:42 < dongs> i think thats t he problem
2013-09-08T15:53:51 < dongs> i cant have black pixel next to white - it siwtches at same time
2013-09-08T15:56:49 < dongs> yep.. reduced black mask by never having same pixel and now black works
2013-09-08T16:03:23 < dongs> http://i.imgur.com/wO6dhMd.jpg
2013-09-08T16:11:13 <+Steffanx> i wonder what will happen when i call you
2013-09-08T16:13:20 < dongs> i'll probably see you on caller ID and ignore the call.
2013-09-08T16:13:46 <+Steffanx> you dont like being called from +31 ?
2013-09-08T16:14:01 < jpa-> call me instead
2013-09-08T16:14:31 < dongs> fuck. i wonder if I should try looking for a different analog switch
2013-09-08T16:14:36 <+Steffanx> oh, you prefer +972
2013-09-08T16:14:53 < jpa-> dongs: so what exactly goes wrong?
2013-09-08T16:15:08 < dongs> jpa-: this http://i.imgur.com/0W3VGSu.png
2013-09-08T16:15:22 < jpa-> saw tat
2013-09-08T16:15:36 < jpa-> but don't understand the problem
2013-09-08T16:15:37 < dongs> http://bcas.tv/paste/results/ojYWky12.html
2013-09-08T16:15:40 < dongs> the problem is this
2013-09-08T16:16:01 < dongs> when I have white pixel followed immediately by black
2013-09-08T16:16:23 < dongs> A0 is on, A1 is off (white) then it switches to A0 off, A1 on (black)
2013-09-08T16:16:33 < dongs> but in the transition, which is precisely on same edge
2013-09-08T16:16:50 < dongs> the analog switch thinks its hitting A1+A0 = 1 (S4) mode.
2013-09-08T16:17:16 < dongs> i think i might give up secondary input and just tie S4 to S1
2013-09-08T16:17:21 < dongs> then it will work as expected.
2013-09-08T16:17:41 < jpa-> if you would have S2 = video_2 and white and black on S3 and S4, it would probably work?
2013-09-08T16:17:49 < jpa-> because then only 1 bit would be changing there
2013-09-08T16:18:08 < dongs> overlay is normally transparent.
2013-09-08T16:18:13 < dongs> i.e. A0/A1 off.
2013-09-08T16:18:14 < jpa-> ah
2013-09-08T16:18:21 < dongs> so thats like 95% of the screen.
2013-09-08T16:18:36 < jpa-> so what does the glitch cause? it's pretty short anyway
2013-09-08T16:18:46 < dongs> it causes switch to S4
2013-09-08T16:18:48 < dongs> which isnt hooked up
2013-09-08T16:18:55 < jpa-> just for a tiny instant, right?
2013-09-08T16:19:01 < dongs> so it sends 0V (or wahtever, floating?) into output.
2013-09-08T16:19:06 < dongs> yes, but that fucks output sync.
2013-09-08T16:19:10 < jpa-> ah
2013-09-08T16:19:16 < dongs> "instant" is more like 20+ns
2013-09-08T16:19:20 < dongs> so its enough to fuck shit up
2013-09-08T16:19:23 < dongs> pixel clock is 450ns
2013-09-08T16:19:37 < dongs> because switch has 25ns switch delay
2013-09-08T16:19:39 < dongs> according todatasheet
2013-09-08T16:19:47 < jpa-> large value resistor so that video_2 floats close to video_in, so it won't mess up sync?
2013-09-08T16:20:18 < dongs> if I bridge video_in to video_2 it works.
2013-09-08T16:21:31 < dongs> shit
2013-09-08T16:21:35 < dongs> maxim switch is way faster.
2013-09-08T16:21:38 < dongs> http://datasheets.maximintegrated.com/en/ds/MAX4634.pdf
2013-09-08T16:21:43 < dongs> 8ns break before make
2013-09-08T16:21:49 < dongs> and 14/6ns turn on/off time
2013-09-08T16:23:13 < jpa-> annoying problem, indeed

2013-09-08T16:25:56 < dongs> uh, thats gonna totally off stuff
2013-09-08T16:26:04 < dongs> when EN is low, outputs are highz or something
2013-09-08T16:26:16 < jpa-> yeah, would probably need a buffer and maybe a small capacitor on the output

2013-09-08T17:44:13 < Laurenceb_> oh of course
2013-09-08T17:44:15 < Laurenceb_> simple
2013-09-08T17:46:26 < dongs> it syncs too good

2013-09-08T17:50:32 < Laurenceb_> oh, glitches?
2013-09-08T17:51:07 < Laurenceb_> there are selectable delay lines on the internal timer signals
2013-09-08T17:51:12 < Laurenceb_> dunno if thats useful
2013-09-08T17:51:40 < Laurenceb_> cant you just format the graphics correctly?
2013-09-08T17:51:58 < Laurenceb_> so the white or black level starts and finishes one pixel before or after the mask
2013-09-08T17:53:59 < dongs> thats what I did.
2013-09-08T17:54:16 < Laurenceb_> lol
2013-09-08T17:54:42 < dongs> i can offset black pixels by 20ns
2013-09-08T17:54:59 < dongs> then i can have adjacent white>black but will need to have black>space>white
2013-09-08T17:55:09 < dongs> also not a big deal.
2013-09-08T17:55:17 < dongs> since black is jsut shadow
2013-09-08T17:55:29 < dongs> 99% of the time its just gonna be white|black>transparent

2013-09-09T01:28:13 < talsit> ah... 16mhz
2013-09-09T01:29:04 < dongs> i'd expect it to be 25-ish
2013-09-09T01:29:10 < dongs> but maybe thats F2.
2013-09-09T01:29:15 < talsit> now i just need a reasonable TCXO at that range
2013-09-09T01:29:21 < dongs> ive successfully used 8/12mhz.
2013-09-09T01:29:25 < talsit> datasheet says: "4-to-16 MHz crystal oscillator"

2013-09-09T01:29:43 < dongs> hokay.
2013-09-09T01:34:06 < talsit> do they not make 12MHz tcxos in decent frequency stability??

2013-09-09T05:44:01 < talsit> cool
2013-09-09T05:44:12 < talsit> but i can use practically any, right
2013-09-09T05:44:34 < talsit> just cut off the key pin
2013-09-09T05:44:42 < dongs> doesnt matter on key pin.
2013-09-09T05:44:52 < dongs> i mean you can use whatever the fuck you want, but standard connector makes sense?
2013-09-09T05:45:07 < dongs> https://www.olimex.com/Products/ARM/JTAG/ARM-JTAG-20-10/ especially when y ou have stuff like this
2013-09-09T05:45:13 < dongs> to interface w/old 20pin giant connector
2013-09-09T05:45:48 < talsit> mouser doesn't stop samtec, by the looks of it
2013-09-09T05:46:08 < dongs> there are tons of compatible 1.27mm pitch shit
2013-09-09T05:46:20 < talsit> yep, exactly
2013-09-09T05:46:33 < dongs> im buying S9012E-05-ND
2013-09-09T05:47:15 < talsit> yeah, looks the same as the one i chose
2013-09-09T05:47:16 < talsit> cool
2013-09-09T05:49:51 < gxti> dongs: so have you actually used coos? thinking about starting something new
2013-09-09T05:49:56 < dongs> yea man
2013-09-09T05:49:59 < dongs> on F1 and F3
2013-09-09T05:50:01 < dongs> works real nice.
2013-09-09T05:50:31 < gxti> i want to be able to wait on a bunch of stuff (queues/semaphores/whatever) in a single thread and chibios not so good at that
2013-09-09T05:50:56 < gxti> unless i make a new thing, and then i need to reimplement the peripherals to use that thing, and then why bother with chibios
2013-09-09T05:52:31 < dongs> it has waiting stuff, prety sure you can wait on single/multiple flags/events
2013-09-09T05:52:40 < dongs> not used its queues but seems to exist
2013-09-09T05:57:32 < dongs> if you want mypatches to use it on F3w/fpu you can haz
2013-09-09T05:57:36 < dongs> on F1 it works as-is
2013-09-09T05:57:58 < gxti> stil just in f1 happy fun land
2013-09-09T05:59:08 < dongs> i like it that it just does OS stuff and stays out of hte way, instead of forcing whole hardware / driver layer shit on you
2013-09-09T05:59:14 < dongs> oh and that it builds w/keil out of the box
2013-09-09T05:59:42 < dongs> feertos would probly wokr too but its so uselessly bloatesd
2013-09-09T05:59:54 < gxti> it also has a crap license
2013-09-09T06:00:03 < gxti> coos was the only permissively licensed one that looked useful
2013-09-09T06:00:06 < dongs> free as in aids?
2013-09-09T06:00:06 < dongs> ahj
2013-09-09T06:00:25 < dongs> you could just be like all chinese and pirate uc/OS or something

2013-09-09T11:20:02 < PaulFertser> Wipster: ah, ok, I don't know any details about MII.

2013-09-09T11:22:26 < Wipster> t1memob, barly any configuration nessesary, some pin strapping but MII mode is default. I give it the refclk it gives me the tx and rx clks. For some reason anything I tx at 100Mb never makes it to my computer, however the board can recieve. I have run out of ideas on whats wrong with it :(

2013-09-09T11:52:40 < PaulFertser> Wipster: are MII registers properly configured?
2013-09-09T11:52:50 < PaulFertser> I mean those on the phy
2013-09-09T11:57:38 < Wipster> PaulFertser, the phy doesn't have MII/RMII selection registers thats done via hardware strapping which I have confirmed. The device in question is a KSZ8041NL.
2013-09-09T12:00:09 < PaulFertser> Wipster: i mean phy configuration registers
2013-09-09T12:00:31 < PaulFertser> Where you can set loopback mode, speed, autoneg etc
2013-09-09T12:02:12 < Wipster> PaulFertser, oh sorry, I believe so I have been in contact with micrel and sent them register dumps and they could not spot anything obvious at their end. I force the speed to test as 10Mb Full/Half duplex works, only 100Mb fails on the transmitting, autonegotiation settles at 100Mb Full. So something works on the line
2013-09-09T12:03:58 < Wipster> and I have used a few link partners, my computer, this netgear Gb switch, another 100M switch

2013-09-09T12:08:14 < PaulFertser> Wipster: probably some issue with transformator connection?
2013-09-09T12:09:39 < Wipster> PaulFertser, possible... I am using a magjack so its intergrated and I have tried with a few other components from farnell just incase I had fakes but no dice
2013-09-09T12:14:47 < Wipster> Unfortunatly I dont have a scope which can decode the line to make sure things are appearing correctly, however I have a trace with persistance which show some activity aside from the usual sync chatter, but not sure if its usefull
2013-09-09T12:23:01 < PaulFertser> Wipster: I assume you've cross-checked with the reference schematics already... Then unfortunately I have no ideas where to look.
2013-09-09T12:24:57 < Wipster> PaulFertser, yeh I have, is pretty much a circuit design I used on an stm32f1 board which worked, might have been a fluke though. Well thanks for suggesting some things :)
2013-09-09T12:24:58 < PaulFertser> Someone was saying here stm32f4's PLL are too jittery for ethernet, but I do not know any details.
2013-09-09T12:25:37 < Wipster> Yeh I am using the system HSE, avoiding any PLL potential issues.

2013-09-09T18:36:21 < Posterdati> zyp: shall I register 0x83 as in handler?
2013-09-09T18:36:56 < zyp> do you have a class driver class for it?
2013-09-09T18:37:33 < zyp> you need a handle_set_configuration() that does hw_conf_ep(0x83, …)
2013-09-09T18:38:17 < Posterdati> virtual void handle_set_configuration(uint8_t configuration)

2013-09-09T18:38:35 < zyp> that should do it
2013-09-09T18:39:05 < Posterdati> mmmh never get ep_ready
2013-09-09T18:39:37 < zyp> you're calling ep_ready(3)?
2013-09-09T18:40:31 < Posterdati> no ep_read(0x83)
2013-09-09T18:40:39 < zyp> that's wrong
2013-09-09T18:40:44 < Posterdati> uh
2013-09-09T18:40:56 < zyp> ep_ready already assumes you have an in endpoint
2013-09-09T18:41:12 < zyp> so ep_ready(3) will check the state of IN 3
2013-09-09T18:41:24 < Posterdati> good

2013-09-10T01:29:20 < Posterdati> hi
2013-09-10T01:29:50 < Posterdati> zyp: please help, calling usb.write trigger a BusFault exceptions
2013-09-10T01:30:36 < zyp> how do you call it?
2013-09-10T01:31:00 < Posterdati> wait I'll paste the class
2013-09-10T01:31:53 < Posterdati> http://pastebin.com/ssgx5j6q
2013-09-10T01:31:55 < Posterdati> ok
2013-09-10T01:32:02 < Posterdati> look at handle_in
2013-09-10T01:32:36 < zyp> did you add handle_in?
2013-09-10T01:32:42 < Posterdati> yes
2013-09-10T01:33:43 < zyp> so, how are you calling handle_in?
2013-09-10T01:34:48 < Posterdati> http://pastebin.com/nKEtwUun
2013-09-10T01:36:38 < Posterdati> even if I try to send out a fixed buffer of 16 uint32_t
2013-09-10T01:36:58 < zyp> unrelated comment: that code is outright dumb
2013-09-10T01:37:08 < zyp> the error stuff
2013-09-10T01:37:29 < Posterdati> ?
2013-09-10T01:39:25 < Posterdati> so?
2013-09-10T01:48:32 < zyp> well, the flow control part
2013-09-10T01:49:03 < zyp> after writing one packet, the next attempt will immediately fail, since endpoint is busy
2013-09-10T01:49:10 < zyp> so you'll have it failing all the time
2013-09-10T01:49:33 < Posterdati> even if I place it in a while loop
2013-09-10T01:49:34 < Posterdati> ?
2013-09-10T01:49:36 < zyp> also, your pointer arithmetics looks wrong
2013-09-10T01:49:52 < zyp> «pData + 16 * i»
2013-09-10T01:50:06 < Posterdati> yes I've got a 2k byte buffer
2013-09-10T01:50:37 < Posterdati> 512 word / 16 word = 32
2013-09-10T01:50:50 < zyp> ok, fair enough
2013-09-10T01:50:57 < zyp> so you intend to send 64 bytes per packet?
2013-09-10T01:51:03 < zyp> because the last argument is in bytes.
2013-09-10T01:51:13 < Posterdati> is not word count???
2013-09-10T01:51:35 < Posterdati> then 16 is wrong
2013-09-10T01:51:39 < zyp> of course not, there is no rule that says that packets have to be word sized
2013-09-10T01:52:03 < Posterdati> then 16 to 64
2013-09-10T01:52:06 < zyp> and yes, it's dumb that the buffer pointer is a word pointer
2013-09-10T01:52:08 < zyp> :p
2013-09-10T01:52:21 < zyp> I just wrote it like that in the first place, and never got around to changing it
2013-09-10T01:53:03 < Posterdati> ok
2013-09-10T01:53:05 < zyp> and now I have plans for a major overhaul to the USB API, so I won't bother changing it until then either
2013-09-10T01:53:08 < Posterdati> so byte based arithmetic
2013-09-10T01:53:17 < zyp> yep
2013-09-10T01:54:22 < Posterdati> may I send more than 64 bytes?
2013-09-10T01:54:52 < zyp> if your endpoint is configured for more
2013-09-10T01:55:05 < Posterdati> what is the maximum?
2013-09-10T01:55:56 < zyp> you set the max packet size in the endpoint descriptor, and should also use the same size in hw_conf_ep
2013-09-10T01:56:30 < zyp> as for what is allowable, that depends on which speed you're running and what kind of endpoint it is
2013-09-10T01:56:40 < zyp> for bulk on FS, 64 is maximum
2013-09-10T01:56:48 < Posterdati> ok
2013-09-10T01:56:57 < zyp> I don't remember what it is for interrupt, it may be more
2013-09-10T01:57:45 < Posterdati> I'll use 64
2013-09-10T01:58:05 < Posterdati> I changed the is with a timeout while :)
2013-09-10T01:58:08 < Posterdati> so
2013-09-10T01:58:16 < Posterdati> is handle_in returns -1 it will retry
2013-09-10T01:58:39 < zyp> I looked it up in the spec; it's 64 for interrupt too
2013-09-10T01:58:43 < zyp> (and also control)
2013-09-10T01:58:55 < Posterdati> ok
2013-09-10T01:59:09 < zyp> 1023 for isochronous
2013-09-10T01:59:40 < Posterdati> BusFault :(
2013-09-10T01:59:51 < zyp> well, what's causing the fault?
2013-09-10T02:00:05 < zyp> check BFAR
2013-09-10T02:00:15 < Posterdati> SCB?
2013-09-10T02:00:22 < zyp> yes, SCB_BFAR
2013-09-10T02:01:03 < Posterdati> pointer to scb is screwed, strange

2013-09-10T02:01:43 < zyp> no wonder you get a busfault if you have corrupt pointers :p
2013-09-10T02:01:52 < Posterdati> yes
2013-09-10T02:01:58 < Posterdati> is the pointer arithmetics then
2013-09-10T02:02:05 < zyp> you probably have a buffer overflow somewhere earlier in the code
2013-09-10T02:02:23 < Posterdati> (sUSB_HID.handle_in(3, (uint32_t *) (pData + 64 * i), 64)
2013-09-10T02:02:37 < zyp> that's wrong.
2013-09-10T02:02:44 < Posterdati> ?
2013-09-10T02:02:47 < Posterdati> why?
2013-09-10T02:02:49 < zyp> ah, no
2013-09-10T02:02:51 < zyp> my bad
2013-09-10T02:02:55 < zyp> read too fast
2013-09-10T02:02:56 < zyp> :)

2013-09-10T02:03:18 < zyp> well
2013-09-10T02:03:32 < zyp> as I said, you probably have a buffer overflow somewhere earlier in the code
2013-09-10T02:03:58 < zyp> which overwrite some pointer the usb code attepts to use with a bad value
2013-09-10T02:04:11 < zyp> then when the usb code tries to access something through that pointer, it fails
2013-09-10T02:04:20 < Posterdati> BFAR?
2013-09-10T02:04:49 < zyp> BFAR is not interesting if the real reason is that the pointer were corrupt
2013-09-10T02:05:50 < zyp> check the backtrace instead to find out which pointer it's trying to access, then set a watchpoint on the address of that pointer, then rerun the code to see who is overwriting that pointer
2013-09-10T02:05:51 < Posterdati> BFAR = 0xe000edf8
2013-09-10T02:08:23 < Posterdati> I added a watchpoint to the SCB pointer and now the program is going!!!
2013-09-10T02:10:15 < Posterdati> no way

2013-09-10T02:16:54 < dongs> maybe
2013-09-10T02:16:58 < dongs> is it?
2013-09-10T02:19:15 < Laurenceb_> theres separate signals mapped from each timer
2013-09-10T02:19:27 < Laurenceb_> one per channel, then update and trig and stuff
2013-09-10T02:19:50 < Laurenceb_> using the advanced timers on F4 you can do it with DMA2

2013-09-10T12:57:55 < karlp> should I be afraid of people planning to do all the testing and calibration of devices in labview?
2013-09-10T12:58:38 < karlp> I guess as long as no-one expects me to set it up...
2013-09-10T13:07:24 < Laurenceb> heh
2013-09-10T13:07:52 < karlp> I don't think this has been fully thought through,
2013-09-10T13:08:06 < karlp> if the assembly guys are going to do it, it's going to cost a fortune
2013-09-10T13:08:31 < karlp> yet somehow we're meant to magically "create the PC software" to run on whatever the assembly house has.

2013-09-10T13:08:53  * Laurenceb is contemplating trying to make PLL2 on F4 fractional -N
2013-09-10T13:12:13 < jpa-> karlp: well.. if anything, labview is most suitable to that kind of thing
2013-09-10T13:12:56 < jpa-> i have seen people build whole applications in labview.. it's horrible :)
2013-09-10T13:13:09 < karlp> yeah, I'm just afraid of it getting out of hand
2013-09-10T13:13:31 < karlp> I guess I appreciate the "we dont' have time for our few developers to go building custom testing software" argument
2013-09-10T13:13:56 < karlp> but it sounds like choosing to go and spend more money down the road when it's "labview or gtfo" for anything else
2013-09-10T13:14:07 < jpa-> the worst problem is mostly just the vendor lock-in.. so one has to realize that if for any reason labview is no longer suitable, you'll have to rebuild it all
2013-09-10T13:14:48 < karlp> I was planning on something more python + usb + gtk/qt
2013-09-10T13:15:12 < karlp> hrm, will have to keep an eye on this.
2013-09-10T13:15:37 < Laurenceb> they use labview for everything here
2013-09-10T13:15:41 < Laurenceb> its quite sad
2013-09-10T13:18:06 < Laurenceb> if i just DMA into the PLLI2S N register...
2013-09-10T13:18:14 < Laurenceb> i can do fractional-N  ?
2013-09-10T13:18:40 < Laurenceb> thatd be a haxored sigma-delta pll setup?

2013-09-10T13:22:56 < jpa-> i wonder if that causes a new relock cycle every time.. and a bunch of lost cycles
2013-09-10T13:31:36 < Laurenceb> its how fractional-n is done
2013-09-10T13:31:52 < Laurenceb> aiui changing n by 1 doesnt cuase huge issues
2013-09-10T13:32:09 < Laurenceb> you get large spurs but theres way to optimise it to reduce spurs

2013-09-10T16:20:21 < dongs> their x/y (approx) and what object it is.
2013-09-10T16:20:35 < dongs> both object and surface can have <some kinda> sensor in them.
2013-09-10T16:20:50 < dongs> passive would be nice.
2013-09-10T16:20:58 < qyx_> ultrasonic beacons + 2 receivers?
2013-09-10T16:21:09 < qyx_> ok, thats not so passive
2013-09-10T16:21:17 < dongs> passive  in teh objects I mean.
2013-09-10T16:21:17 < zyp> only x/y, not orientation?
2013-09-10T16:21:20 < dongs> desk can be active.

2013-09-10T16:21:51 < zyp> camera/cv is unfeasible?
2013-09-10T16:22:00 < dongs> yeah, has to be in teh desk

2013-09-10T16:22:55 < zyp> rfid would give type, but I'm not sure how to handle position
2013-09-10T16:23:11 <+Steffanx> Make it very short range + lots of receivers i guess?
2013-09-10T16:23:27 < dongs> zyp: what if theres several blocks on teh desk.
2013-09-10T16:23:59 < karlp> how does the wavetable/surface thingy do it?
2013-09-10T16:24:10 < karlp> camera underneath plus what else?
2013-09-10T16:24:12 < qyx_> maybe you could do x/y antenna grid for it
2013-09-10T16:24:46 < dongs> shit like wacom tablet, what does that use? can that only handle a single pressure point?
2013-09-10T16:24:48 < karlp> my thesis used a bunch LDRs and a translucent board, but it knew where the pieces started, and what were legal moves, so it didn't have to identify them

2013-09-10T16:26:44 < dongs> i must be searching for some wrong shit
2013-09-10T16:26:49 < dongs> hasnt this been done like many times
2013-09-10T16:26:56 <+Steffanx> probably

2013-09-10T16:27:33 < gxti> with wacom the pen has some of the smarts
2013-09-10T16:27:47 < karlp> only one object too
2013-09-10T16:28:08 < dongs> smarts in the blocks is OK
2013-09-10T16:28:18 < dongs> preferably passive tho
2013-09-10T16:28:19 < qyx_> there are IR lcd digitizers used on large scale kiosk lcds
2013-09-10T16:28:25 < dongs> or some sorta inductive charging type shit would be ok too
2013-09-10T16:28:37 < dongs> IR digitizer can only deal wiht one object tho
2013-09-10T16:28:49 < karlp> put QR codes on the bottom of the blocks ;)
2013-09-10T16:28:51 < qyx_> i have one with pseudo-multitouch support
2013-09-10T16:29:02 < qyx_> pseudo = it works sometimes
2013-09-10T16:29:16 < zyp> dongs, I'm a bit curious about how the panasonic chargepad works
2013-09-10T16:29:28 < dongs> zyp, good fucking question.
2013-09-10T16:29:29 < zyp> I mean, how it locates the receiver coil
2013-09-10T16:29:33 < dongs> yeah
2013-09-10T16:29:38 < dongs> but thats still just one object
2013-09-10T16:30:23 < zyp> been tempted to pick one apart and check how it looks inside

2013-09-10T16:34:20 < dongs> how do you think it knows you put phone on it?
2013-09-10T16:34:55 < zyp> I suspect that there's multiple coils
2013-09-10T16:35:23 < dongs> it has a butotn
2013-09-10T16:35:29 < dongs> what is it for?
2013-09-10T16:35:39 < dongs> oh
2013-09-10T16:35:42 < dongs> bvutton puts it in center
2013-09-10T16:35:44 < dongs> always
2013-09-10T16:35:46 < dongs> and turns on
2013-09-10T16:35:49 < zyp> so something forms an antenna that can measure the position of the receiver coil
2013-09-10T16:36:00 < zyp> and then there's a charging coil on some x/y mechanism
2013-09-10T16:36:03 < dongs> my pal says something about "mutual inductance"
2013-09-10T16:36:32 < zyp> unless the charging coil itself can measure the relative position

2013-09-10T16:38:22 < emeb_mac> apparently cheap
2013-09-10T16:38:22 < zyp> people have been talking about using one in a work project
2013-09-10T16:38:43 < zyp> apparently my company is affiliated with a company affiliated with AMS or something
2013-09-10T16:38:47 < qyx_> bldc/ac sync motors use motor winding saturation / inductance change to measure starting position

2013-09-10T16:40:58 < qyx_> theres also other way probably, you can use the tag system from shopping malls

2013-09-10T16:42:33 < qyx_> this way you should be able to track different objects and maybe measure position somehow using triangulation

2013-09-10T19:43:08 < zyp> «And after telling you all of this, I’ll let you cry in tears and desperately wating to know what to do by saying goodbye !» <- was looking for a summary, found this
2013-09-10T19:43:21 < zyp> because I'm not gonna read all that just for a laugh :p
2013-09-10T19:43:38 < jpa-> in a way, that article is totally right.. but it still is quite miserable :)
2013-09-10T19:44:44 < jpa-> zyp: btw, i've been learning scons this week; it's very nice, only that my build code is growing to be quite long :)
2013-09-10T19:44:58 < zyp> :)
2013-09-10T19:45:27 < zyp> I find it to be shorter than the equivalent makefile :p
2013-09-10T19:45:34 < jpa-> sure
2013-09-10T19:45:45 < jpa-> just that i wouldn't be doing all that crazy stuff in a makefile :P
2013-09-10T19:45:48 < zyp> what are you doing with it that makes it long?
2013-09-10T19:46:13 < zyp> something even more elaborate than my SelectMCU() stuff?
2013-09-10T19:46:20 < jpa-> mostly defining the builders for calling protoc, my generator script, running the tests, checking results etc.
2013-09-10T19:46:45 < zyp> ah
2013-09-10T19:46:53 < jpa-> a lot of things that are mostly just 1 line in makefile, because everything has been hardcoded so far :P
2013-09-10T19:47:25 < zyp> I've been thinking about writing a linker script generator
2013-09-10T19:47:46 < jpa-> https://code.google.com/p/nanopb/source/browse/tests/site_scons/site_init.py?name=dev_tests_using_scons  quite a mess already, even though it is only 100 lines
2013-09-10T19:48:07 < jpa-> maybe one day i'll make those builders into real "tools"
2013-09-10T19:48:24 < emeb> talsit: I noticed that the F4 parts were more $$ the other day too.
2013-09-10T19:48:36 < emeb> still pretty cheap at Verical though if you want qty.
2013-09-10T19:49:07 < zyp> because while writing a linker script for each chip family is rather doable, it doesn't accord for stuff like bootloaders and other special configurations

2013-09-10T20:41:18 < gxti> i don't see too much utility in fully generating linker scripts, so far the most complex thing i've done is write a python thingy that relocates the start-of-flash to accomodate a bootloader

2013-09-10T20:43:44 < zyp> not interested
2013-09-10T20:44:56 < gxti> i'm just getting started building the coos stack for my stm32f107 thing and all the chip-specific crap that chibios was doing for me is irritating

2013-09-11T05:43:25 < emeb_mac> dongs: another 400km?
2013-09-11T05:45:29 < dongs> yeah fucking done
2013-09-11T05:49:25 < dongs> so did apple release anything useful
2013-09-11T05:49:43 < emeb_mac> ya - NSA fingerprint collector
2013-09-11T05:51:09 < dongs> ya just saw that
2013-09-11T05:51:12 < dongs> also, wat  1136-by-640-pixel resolution at 326 ppi
2013-09-11T05:51:15 < dongs> fail?
2013-09-11T05:52:05 < dongs> Support for display of multiple languages and characters simultaneously
2013-09-11T05:52:06 < dongs> wow, thanks apple
2013-09-11T05:52:11 < dongs> innovation at its finest
2013-09-11T05:52:59 < emeb_mac> plus, 64-bit iOS
2013-09-11T05:53:19 < dongs> i'm sure total number of people who care about this is very close to zero
2013-09-11T05:53:39 < dongs> cuz like whats the point of a 64bit OS when you have like 1gb ram???
2013-09-11T05:53:45 < dongs> having problems wiht memoryaddressing???
2013-09-11T05:53:47 < emeb_mac> I'm sure total number of people who care about this far exceeds the number of people who understand what it means.

2013-09-11T11:30:12 < jpa-> Robint91: hmm, i can't figure out a way, because it would need a PLL1 VCO of 480 MHz to get both 160 MHz and 48 MHz out, but 432 MHz is the maximum specified for VCO
2013-09-11T11:30:26 < jpa-> but i'm not the best person at figuring these out, i've failed before
2013-09-11T11:30:53 < Robint91> jpa-, I have found out
2013-09-11T11:31:08 < Robint91> jpa-, I need a timer period of 31.25ns
2013-09-11T11:31:14 < Robint91> 32MHz
2013-09-11T11:31:57 < jpa-> i think 128 MHz core clock could work

2013-09-11T14:06:12 < zyp> I think I once worked out that sysclk have to be divisable by 24MHz to be able to use usb
2013-09-11T14:06:56 < jpa-> that is sufficient but not always necessary i think
2013-09-11T14:08:19 < jpa-> ah.. actually 128MHz wouldn't work because P cannot be 3
2013-09-11T14:10:20 < jpa-> Robint91: maybe you should use the PLLI2S to generate a 32MHz clock and take it out of MCO1 and loop it back to timer clock input :)
2013-09-11T14:12:21 < zyp> 96MHz should work

2013-09-11T14:39:12 < jpa-> and it is difficult to get a clock that is divisible by both 48MHz and by 32MHz

2013-09-11T14:42:20 < Robint91> jpa-, damm
2013-09-11T14:43:11 < jpa-> i guess your options are: 1) use 96MHz   2) loop back from MCO1 to timer pin  3) violate the VCO max freq spec  
2013-09-11T14:45:17 < Robint91> jpa-, usb needs 48MHz
2013-09-11T14:45:19 < Robint91> ?
2013-09-11T14:48:13 < dongs> jpa-: timers have arbitrary divisors, and you can adjust final freq by period
2013-09-11T14:48:20 < dongs> cant you arrive at 32mhz w/that?
2013-09-11T14:52:32 < Robint91> dongs, jpa- I want to use a 32bit timer have its lower 16 bit align with a specift amount of time that is divisible by a specific amount of time
2013-09-11T14:53:07 < Robint91> jpa-, the 16bit need to overflow in like 2.048 ms
2013-09-11T14:56:28 < jpa-> dongs: the divisor must be integer, no way to divide e.g. 168 MHz to 32 MHz
2013-09-11T14:58:26 < jpa-> Robint91: what is the purpose?

2013-09-11T15:01:07 < jpa-> do you need all the 16 bits of fractional precision?
2013-09-11T15:01:08 < Robint91> I want to divide X amount in time into different timeslots
2013-09-11T15:01:24 < jpa-> 14 bits would be easy
2013-09-11T15:01:30 < Robint91> but those need to be synchronised very well
2013-09-11T15:02:04 < Robint91> to get the resolution I need to have a maximum sample time of 300ns
2013-09-11T15:03:26 < jpa-> so just run the timer at 8 MHz and you are fine?

2013-09-11T16:29:56 < Robint91> Laurenceb, DAC + filter?
2013-09-11T16:30:15 < Robint91> but driving 50 Ohm should be possible

2013-09-11T23:34:10 < Buizel> I'm trying to set up SPI with an STM32F303. I have it set up as a master, and configured for 8-bit data lengths. When I initiate a transfer, it clocks out the correct 8 bits from the data register, but also performs a full 16 clocks on the CLK pin. Is this expected behavior?
2013-09-11T23:34:20 < Buizel> I would have expected it to only perform 8 clocks per transfer when configured for 8-bit data lengths, but perhaps I'm missing something there.

2013-09-12T00:08:09 < gxti> Buizel: either you sent two bytes, or you didn't actually set 8 bit mode, perhaps because the SPI was already enabled when you tried to do so
2013-09-12T00:13:07 < Buizel> The SPI hardware, at reset values, defaults to 8-bit mode. I've also ensured the SPI hardware itself remains disabled while setting it's configuration registers. Every other aspect of the SPI works, it's just this one little thing that's causing me headaches.
2013-09-12T00:13:51 < Buizel> I see on the myST forums that others have experianced this problem as well. Of course, nobody posts their solution to how they solved it :P

2013-09-12T00:47:22 < karlp> Buizel: no, it doesn't default to 8 bit mode at reset. it defaults to 0, and if you try and write an invalid value, it gets forced to 0111 (8bit)
2013-09-12T00:47:31 < karlp> f3 has a totally different size thing thatn the rest
2013-09-12T00:48:31 < qyx_> i didn't have this problem on f303 with l3g4200
2013-09-12T00:48:37 < qyx_> at least not with chibios
2013-09-12T00:51:32 < gxti> hmmm... making small changes to my code results in hard faults happening or not happening at random places
2013-09-12T00:51:53 < gxti> but busfault/usagefault/memmanage is apparently not being hit, either that or it fails getting there
2013-09-12T00:51:53 < qyx_> do you have enough stack space?
2013-09-12T00:52:12 < qyx_> hm
2013-09-12T00:53:35 < gxti> i embiggened the idle stack, all stacks are now at least 100 words which is more than enough considering i barely have any code right now
2013-09-12T00:54:52 < gxti> msp and psp both in bounds by the time hardfault trips
2013-09-12T00:56:14 < zyp> Buizel, I ran into the same problem as you, it's a weird new feature in F3
2013-09-12T00:57:05 < gxti> oh, and HFSR = FORCED which means something is wrong with my bus/usage/mem handlers and/or vector table.
2013-09-12T00:57:31 < gxti> because they just read out CFSR and then spin forever, but when i attach gdb it's always in hardfault.
2013-09-12T00:57:47 < zyp> Buizel, it checks the register access width (of DR), and if you do a larger write than 8 bits, when it's configured to 8 bits or less, it assumes you want to write two words, and queues both
2013-09-12T00:57:59 < zyp> it's a new feature since it got the FIFO stuff
2013-09-12T00:58:25 < zyp> older chips didn't have a FIFO on SPI

2013-09-12T01:01:34 < karlp> yuck :|
2013-09-12T01:01:42 < karlp> you can't set the fifo to off or single deep or something?
2013-09-12T01:01:54 < zyp> no
2013-09-12T01:03:01 <+dekar> I wonder why the STM32F4s flash is organized in sectors of varying sizes.
2013-09-12T01:03:55 < zyp> probably to strike a balance between complexity and granularity
2013-09-12T01:05:11 <+dekar> It surely makes it harder to just iterate over it as you need. :/
2013-09-12T01:08:35 < zyp> isn't sectors just for locking? unless you're messing with that you shouldn't need to touch it
2013-09-12T01:09:16 <+dekar> It's also for erasing.
2013-09-12T01:09:39 < zyp> are you sure? I thought erase had a smaller granularity
2013-09-12T01:09:39 < gxti> CFSR is set to 'imprecise' which is helpful
2013-09-12T01:10:03 < gxti> still guessing i buggered the linker script.
2013-09-12T01:10:35 <+dekar> At least the periph lib lacks FLASH_ErasePage() for the F4, it just has FLASH_EraseSector().
2013-09-12T01:12:04 < gxti> is it not possible to access SFRs from gdb, or is that a misconfiguration? i always get 'Cannot access memory'
2013-09-12T01:19:41 < zyp> set memory inaccessible-by-default off
2013-09-12T01:20:10 < gxti> oh, busfault etc are disabled by default. that explains why it's going straight to hardfault, at least.

2013-09-12T04:44:56 < dongs> how does it affect "code size"?/
2013-09-12T04:45:04 < dongs> are you looking at outputted elf, or elf-size thing

2013-09-12T06:34:44 < DLPeterson> dongs, I read those, it didn't help me understand very well
2013-09-12T06:35:00 < DLPeterson> dongs, I was just looking at the file size of the elf
2013-09-12T06:35:11 < DLPeterson> dongs, maybe i should be looking at the size of the bin/hex file instead?
2013-09-12T06:35:37 < dongs> uh
2013-09-12T06:35:44 < dongs> you should be looking at whatever arm-none-wahtever-size gives you
2013-09-12T06:35:49 < dongs> for sections
2013-09-12T06:35:55 < dongs> elf size = shitton of debug info
2013-09-12T06:36:50 < gxti> bin file will be about right, too
2013-09-12T06:37:21 < gxti> it might have holes in it if you have multiple flash sections? not sure
2013-09-12T06:40:39 < DLPeterson> oops, my bad. It was a link option that was making the difference
2013-09-12T06:42:00 < DLPeterson> this makes the difference:  -Wl,-u,vfprintf
2013-09-12T06:44:44 < dongs> i heard  gnu printf is fuicking HUGE
2013-09-12T06:47:51 < DLPeterson> i'm working on a project that has a Makefile that was clearly cobbled together without knowing half of what anything did and I'm pretty sure they don't need that linker command
2013-09-12T06:47:59 < DLPeterson> it compiles without it
2013-09-12T06:48:18 < DLPeterson> but changes the code size
2013-09-12T06:48:31 < gxti> if you look up what -u does you'll understand why
2013-09-12T06:49:13 < dongs> heh
2013-09-12T06:49:16 < dongs> http://ftp.gnu.org/pub/old-gnu/Manuals/ld-2.9.1/html_node/ld_3.html
2013-09-12T06:50:24 < GargantuaSauce_> sounds like a pretty typical makefile to me
2013-09-12T06:50:44 < DLPeterson> yeah, I read man ld and saw that... so basically it is like adding the text for a function that isn't actually needed, correct?
2013-09-12T06:50:51 < gxti> DLPeterson: yes
2013-09-12T06:51:04 < DLPeterson> when would you ever want to do that?
2013-09-12T06:51:08 < DLPeterson> seems odd
2013-09-12T06:51:33 < dongs> i can see why

2013-09-12T06:51:37 < dongs> you're using gcc
2013-09-12T06:51:39 < gxti> sometimes for embedded stuff you need to prevent certain symbols from being garbage collected, but you usually do that with the linker script
2013-09-12T06:51:39 < dongs> oyu have no idea what youre doing

2013-09-12T06:52:06 < dongs> you start undefining symbols, beause gnu linker is too fucking dumb to clean out unused symbols by itself
2013-09-12T06:52:25 < dongs> gxti: uh doenst -u do the opposite
2013-09-12T06:52:32 < DLPeterson> dongs, thats really not helpful, why don't you try a different approach.

2013-09-12T06:53:13 < DLPeterson> i'm trying to clean up an existing project; I can't change the toolchain.
2013-09-12T06:53:16 < gxti> dongs: in this context, 'force it to be undefined' means 'make the linker solve it'
2013-09-12T06:53:20 < gxti> in other words, require it
2013-09-12T06:54:52 < gxti> same as any symbol referenced in one .c file that isn't defined there
2013-09-12T06:56:44 < DLPeterson> gxti, isn't it true though that if that function was needed, but the library to which it belongs wasn't being linked to explicitly, I would get a linker error?
2013-09-12T06:57:47 < gxti> vfprintf is part of libc so it's implicitly linked unless you have -nostdlib or something
2013-09-12T06:58:04 < gxti> but if it was -u butts then yeah, it would fail unless butts was available for linking
2013-09-12T06:59:06 < DLPeterson> gxti, it is explained here: http://www.nongnu.org/avr-libc/user-manual/group__avr__stdio.html#gaa3b98c0d17b35642c0f3e4649092b9f1
2013-09-12T06:59:16 < DLPeterson> sorry to post AVR stuff on STM32 channel
2013-09-12T06:59:24 < gxti> yes i know what vfprintf is
2013-09-12T07:00:04 < DLPeterson> well, they discuss the reason for needing to do -Wl,-u,vfprintf in that link,
2013-09-12T07:00:29 < DLPeterson> I guess it is an implementation detail of the avr-libc
2013-09-12T07:00:29 < dongs> you know whats hilarious
2013-09-12T07:00:36 < dongs> keil printf does floats, etc
2013-09-12T07:00:39 < dongs> and its SMALLER
2013-09-12T07:00:49 < dongs> than gnu printf that only does integers (and some limited subset of formatting)
2013-09-12T07:00:50 < DLPeterson> dongs, I really don't care.
2013-09-12T07:00:52 < dongs> I do
2013-09-12T07:01:03 < dongs> just sayin man.
2013-09-12T07:01:16 < gxti> gnu printf isn't really meant for microcontrollers
2013-09-12T07:01:17 < DLPeterson> what would you suggest I do with that information?
2013-09-12T07:01:41 < DLPeterson> avr-libc is specifically designed for AVR chips; I think it specifically is meant for microcontrollers.
2013-09-12T07:03:11 < DLPeterson> dongs, full floating point formatting for avr-libc costs about 3k as compared to not having it.
2013-09-12T07:03:11 < gxti> ok have fun, i'm going to keep working on i2c stuff.
2013-09-12T07:03:18 < DLPeterson> gxti, thanks for the help.
2013-09-12T07:03:19 < gxti> instead of watching you feed the troll
2013-09-12T07:03:25 < gxti> which, while amusing, is unproductive

2013-09-12T11:04:42 < dongs> also thats dc/dc so i still need a rectifier
2013-09-12T11:04:46 < qyx_> actually beyond the limit
2013-09-12T11:04:52 < qyx_> if you rectify ac

2013-09-12T11:06:24 < dongs> is rectified shit gonna be like +25% or something?
2013-09-12T11:06:59 < dongs> or wait
2013-09-12T11:07:13 < dongs> according to interbutt, 100V AC will be like 64V DC rectified

2013-09-12T13:26:16 < zyp> one of my coworkers were looking for something like that, so I were suggesting it, but didn't remember what it was called
2013-09-12T13:26:22 < karlp> it's not an bad concept, just marketting it as an arduino is an odd concept
2013-09-12T13:26:33 < karlp> zyp: "gainstrong" oolite is another one,

2013-09-12T13:33:26 < karlp> not even looking for one, just using it with openwrt
2013-09-12T13:34:06 < Laurenceb> are there open drivers for the wifi?
2013-09-12T13:35:14 < karlp> sure, this is atheros not broadcom

2013-09-12T14:07:03 <+Steffanx> the Atlantic ocean that is.
2013-09-12T14:07:06 < Laurenceb> yes
2013-09-12T14:07:50 < Laurenceb> if there is brown rain i will know he arrived in uk

2013-09-12T14:53:51 < dongs> im curious about mat[2][1] there
2013-09-12T14:53:56 < Laurenceb> something i wrote for you dongs
2013-09-12T14:53:57 < Laurenceb> http://ukhas.org.uk/code:7_state_ekf_with_bias
2013-09-12T14:54:01 < dongs> my code is (sinzcosx * siny) - (coszsinx)
2013-09-12T14:54:23 < dongs> needs less spaces Laurenceb
2013-09-12T14:54:52 < jpa-> it all depends on how you define the angles
2013-09-12T14:55:08 < dongs> alpha = X, beta = Y, gamma =Z
2013-09-12T14:55:16 <+Steffanx> dont even look dongs.. really dont open his link
2013-09-12T14:55:20 < dongs> in my case
2013-09-12T14:55:21 < jpa-> you use euler angles or SORA?
2013-09-12T14:56:37 < dongs> jpa-: input to matrix is rpy so i dunno
2013-09-12T14:57:27 < Laurenceb> dump to pc and try in octave
2013-09-12T14:57:38 < jpa-> rpy?
2013-09-12T14:57:39 < dongs> it works
2013-09-12T14:57:42 <+Steffanx> or pro madlab?
2013-09-12T14:57:44 < dongs> the rest of matrix matches
2013-09-12T14:57:53 < Laurenceb> lol madlab
2013-09-12T14:57:55 < dongs> im curious if that [2][1] is equivalent
2013-09-12T14:58:01 < dongs> in C i don't think it is because signs are different
2013-09-12T14:58:25 < zyp> remember that cos(x) = -cos(x)
2013-09-12T14:58:35 < Laurenceb> wtf
2013-09-12T14:58:45 < Laurenceb>  cos(x) = cos(-x)
2013-09-12T14:58:56 < zyp> ah, right
2013-09-12T14:59:10 < zyp> that's what I meant
2013-09-12T14:59:11 < zyp> :p
2013-09-12T14:59:41 < zyp> also, which is [2][1]? do you count rows,cols or cols,rows, and starting from 0 or 1?
2013-09-12T15:00:41 < dongs> right side 1 down
2013-09-12T15:00:50 < dongs> -cosYsinA+cosAsinBsinY
2013-09-12T15:00:51 < dongs> that one
2013-09-12T15:01:15 < jpa-> lol, cols,rows and 0-based.. the craziest way :)
2013-09-12T15:02:14 < zyp> yep, it's eqivalent
2013-09-12T15:02:30 < jpa-> dongs: open sores to the rescue http://paste.dy.fi/ee3/plain
2013-09-12T15:02:34 < zyp> if you swap the order it becomes cosAsinBsinY-cosYsinA
2013-09-12T15:02:44 < zyp> then swap the variables, and you have the same as your
2013-09-12T15:02:54 < dongs> ok
2013-09-12T15:03:02 < zyp> cosx siny sinz - sinx cosz
2013-09-12T15:03:49 < dongs> OK
2013-09-12T15:03:56 < dongs> so matrix is correct
2013-09-12T15:05:54 < jpa-> as long as you are happy with your small angle approximations :)
2013-09-12T15:06:17 < jpa-> (or the input data is really euler angles in that particular configuration..)
2013-09-12T15:08:18 < dongs> jpa-: hm?
2013-09-12T15:09:14 < jpa-> rotations are complex
2013-09-12T15:09:58 < dongs> input is gyro delta
2013-09-12T15:10:10 < dongs> whatever the fuck that is
2013-09-12T15:10:10 < dongs> dps*scale
2013-09-12T15:10:14 < jpa-> yeah, probably small enough that nothing matters
2013-09-12T15:10:37 < dongs> yes but where is approximation in this case then?
2013-09-12T15:10:59 < jpa-> in that the gyro data is really more close to simultaneous rotation angles than to euler angles
2013-09-12T15:11:14 < jpa-> it doesn't rotate "X first, then Y, then Z" like in that matrix
2013-09-12T15:11:33 < jpa-> so if the rotation was really large and in two directions simultaneously, your results would be wrong
2013-09-12T15:13:10 < jpa-> you could probably replace every single cos() in that matrix with 1 and it would still work just as well for you :P
2013-09-12T15:13:29 < dongs> thats what it was originally.
2013-09-12T15:14:14 < dongs> entire matrix was optimized into small angle approximation just swapping signs on stuff
2013-09-12T15:15:01 < zyp> a gyro sample is a rotation speed vector
2013-09-12T15:15:32 < zyp> meaning that the length of the vector corresponds to the rotation speed, and the direction indicates the axis you rotate around
2013-09-12T15:15:58 < dongs> yeah.
2013-09-12T15:16:17 < jpa-> and that matrix does not do that thing :)
2013-09-12T15:16:30 < zyp> no, euler angles is a completely different thing
2013-09-12T15:18:11 <+Steffanx> Laurenceb, don't post my links in #highaltitude without permission..
2013-09-12T15:18:24 < Laurenceb> sorry dearest master
2013-09-12T15:18:35 < Laurenceb> i will promise not to disobey you
2013-09-12T15:18:42 < zyp> the reason quaternions is nice for this kind of thing is that a quaternion is not very different from a rotation vector
2013-09-12T15:21:38 < jpa-> yeah, and you don't need all those sines and cosines either
2013-09-12T15:23:00 < Laurenceb> http://ukhas.org.uk/code:7_state_ekf_with_bias
2013-09-12T15:23:17 < Laurenceb> ^bindone
2013-09-12T15:23:29 < zyp> for a vector v = {x, y, z}, you have a = abs(v) and u = v/a, then the quaternion will be q = {cos(a), sin(a) u}/2
2013-09-12T15:24:00 < zyp> and with small angle approximations, cos(a) turns into 1 and sin(a) turns into a
2013-09-12T15:25:11 < zyp> hmm, I put the /2 at the wrong place, it's cos(a/2) and sin(a/2)
2013-09-12T15:25:30 < zyp> anyway, the end result is q = {1, v/2}

2013-09-12T16:19:34 < zyp> made some modifications yesterday, adding another connector and pads for SPI for possible future expansion
2013-09-12T16:19:50 < dongs> sure
2013-09-12T16:19:54 < zyp> and fixed the xh footprint fuckup, of course :p
2013-09-12T16:21:02 < zyp> should be more or less done, I just need a bit more time to think over it, and I'll be away for the weekend, so I'll probably finish it up next week

2013-09-12T16:23:07 < dongs> like ICs/QFN/etc.
2013-09-12T16:23:34 < jpa-> zyp's making 100 arcade controllers?
2013-09-12T16:23:57 < zyp> I think the stm32 is the only part that needs to be oriented, and can fit in multiple orientations :p
2013-09-12T16:24:12 < zyp> jpa-, just usb adapters
2013-09-12T16:24:38 < Laurenceb> dongs spotted irl http://i.imgur.com/xGxhok1.jpg
2013-09-12T16:25:23 < dongs> this maxima shit looks neat
2013-09-12T16:25:28 < dongs> and looks like they have windows version
2013-09-12T16:25:34 < dongs> probably full of gnu/aids but as long as its in a single dir its ok
2013-09-12T16:25:45 < jpa-> it's spread and eat all your windows
2013-09-12T16:25:52 < jpa-> and replace it with lunix
2013-09-12T16:25:52 < dongs> http://sourceforge.net/projects/maxima/files/ haha
2013-09-12T16:25:55 < dongs> you can see what people are downloading
2013-09-12T16:26:00 < dongs> check the 'downloads' graph
2013-09-12T16:26:08 < dongs> sores/luunix/mactrash are flatlined
2013-09-12T16:26:11 < dongs> windows is a proper graph
2013-09-12T16:26:21 < jpa-> dongs: yeah, because on linux you don't download random files from internet, you just install from package manager
2013-09-12T16:26:30 < Laurenceb> owned
2013-09-12T16:26:43 < zyp> «GPL CAS based on DOE-MACSYMA»
2013-09-12T16:26:49 < zyp> too high acronym density
2013-09-12T16:26:51 < dongs> lol package manager
2013-09-12T16:27:33 < jpa-> windows 8 has windows store bukkage manager also, but only accepts thrash in there
2013-09-12T16:27:47 < zyp> hmm
2013-09-12T16:28:12 < zyp> dongs, should the xh connectors be in the x/y file, or only smt parts?
2013-09-12T16:28:30 < jpa-> my bet: doesn't matter
2013-09-12T16:28:53 < zyp> that's what I would also guess
2013-09-12T16:28:59 < dongs> zyp, how are tehy coming
2013-09-12T16:29:00 < dongs> tape?
2013-09-12T16:29:10 < dongs> if they're on tape, they'll be dicknplaced
2013-09-12T16:29:11 < dongs> if they're in a bag they'll be hand-placed lol
2013-09-12T16:29:18 < zyp> the one I got just came in a bag
2013-09-12T16:29:21 < zyp> ones*
2013-09-12T16:29:23 < dongs> hm
2013-09-12T16:29:31 < dongs> that sucx.
2013-09-12T16:29:31 < dongs> oh, wait, they're dips anyway
2013-09-12T16:29:34 < zyp> bag of 150 or so, what was I got
2013-09-12T16:29:34 < dongs> nvm
2013-09-12T16:29:35 < zyp> yes
2013-09-12T16:29:51 < dongs> yeah doesnt matter then
2013-09-12T16:30:17 < dongs> most generic passives can be picked up locally
2013-09-12T16:30:22 < dongs> unless you wanna ship everything
2013-09-12T16:30:39 < dongs> can also probably source 303's if you want unless you llready have them
2013-09-12T16:31:22 < zyp> I don't have anything, everything is available from digikey
2013-09-12T16:32:01 < zyp> hmm, I think digikey only have 303RCs, smaller would be fine
2013-09-12T16:32:03 < Robint91> does someone know 10 or 12 bit DACs with daisy chain output?
2013-09-12T16:34:59 < jpa-> what is daisy chain output? spi?
2013-09-12T16:36:03 < Robint91> yeah
2013-09-12T16:36:06 < Robint91> SPI like
2013-09-12T16:36:20 < Robint91> some dacs have like a CS daisy chaining
2013-09-12T16:36:44 < dongs> fsidwhat does that achieve

2013-09-12T17:20:55 < gxti> is it normal for f1 i2c to come out of reset with BUSY already set?
2013-09-12T17:21:25 < jpa-> gxti: maybe your pull-ups are not working and it thinks that the bus is busy?
2013-09-12T17:22:00 < gxti> the hardware works fine, i'm just switching from chibios which did everything for me to a custom driver
2013-09-12T17:24:58 < gxti> hmm, toggling RCC reset might do the trick

2013-09-12T17:29:03 < dongs> it was way worse when it did that
2013-09-12T17:29:28 < gxti> after rcc reset now at least the status flags are working. not getting ACK from device but i probably pissed it off...
2013-09-12T17:29:43 < dongs> gxti: are you clocking out i2c bus before starting up hardware i2c

2013-09-12T19:48:20 < emeb> needs MMU
2013-09-12T19:49:52 < gxti> hmm, so i have a modified version of jpa-'s hardfault handler, and while "info reg" shows that it is setting msp=psp, the backtrace still shows the main stack
2013-09-12T19:50:56 < gxti> also reading out PSP+20 shows the address of the function where the fault is, so psp is definitely the right stack

2013-09-12T20:27:53 <+Steffanx> So, conclusion: it's safe to let jpa- fly your copter.
2013-09-12T20:27:59 < Tectu> public tectu needs help with his homeworks (english):   "Even if you're a fast reader, it can take a .... amount of time to finish a novel, for example." And now there should match one of these four words into that gap:   plentiful, borad, considerable, lasting    I picked 'considerable', does that seem to be right to you too?
2013-09-12T20:29:01 <+Steffanx> Yes.
2013-09-12T20:29:31 < Tectu> I hope public steffanx is not trolling
2013-09-12T20:29:43 < gxti> don't listen to the dutchman, 'borad' is obviously the best choice even though it is not a word
2013-09-12T20:29:59 < Tectu> broad*
2013-09-12T20:30:03 < gxti> but yes, considerable is best
2013-09-12T20:30:16 <+Steffanx> Tectu, Tectu .. i never troll you in public.
2013-09-12T20:30:52 < jpa-> yeah, considering that Steffanx is not trolling, considerable seems the most considerable consideration here
2013-09-12T20:31:20 < gxti> considerably.
2013-09-12T20:31:27 <+Steffanx> Are you tall jpa-?
2013-09-12T20:31:39 <+Steffanx> if so, then you are that Borad.
2013-09-12T20:31:40 < Tectu> if you consider 1700mm to be tall ;)
2013-09-12T20:32:26 < jpa-> i'm 1820mm IIRC
2013-09-12T20:37:07 < Tectu> and the other dimension?

2013-09-12T20:38:49 < gxti> it's a risk you have to consider
2013-09-12T20:38:56 < jpa-> it's lasting considerably so far
2013-09-12T20:39:11 <+Steffanx> Just think about your ex-gfx Tectu

2013-09-12T20:39:43 < gxti> it's a nice distraction from Laurenceb's c ode

2013-09-12T20:45:55 < Tectu> dafuq.... Did github screw up the code viewer again? it's all like without newlines and shit

2013-09-12T21:03:34 < jpa-> ah, there is youtube anyway
2013-09-12T21:04:09 < zyp> doesn't open here either, it's probably overloaded

2013-09-12T21:04:51 <+Steffanx> not completely, but.. probably too unrealistic:P
2013-09-12T21:04:51 < jpa-> it's borderline possible, but every block would end up costing so much more that it is not worth it
2013-09-12T21:05:14 <+Steffanx> people pay $600 for an iphone as well.
2013-09-12T21:05:22 <+Steffanx> or a random android phone
2013-09-12T21:05:23 <+Steffanx> or ..
2013-09-12T21:05:36 < zyp> I see the main problem as IO between the blocks
2013-09-12T21:06:18 < jpa-> RAM and CPU would have to be on the same block.. otherwise not so critical, USB could work for example
2013-09-12T21:06:35 <+Steffanx> but the camera...
2013-09-12T21:06:40 < jpa-> usb webcams..
2013-09-12T21:06:41 <+Steffanx> for video.
2013-09-12T21:06:53 < zyp> jpa-, which USB? HS, SS or SS+?
2013-09-12T21:06:58 < jpa-> HS
2013-09-12T21:07:36 < zyp> will be a bottleneck in the not so far future
2013-09-12T21:07:59 < jpa-> probably yeah
2013-09-12T21:08:03 < zyp> modern SoC devboards already come with SS
2013-09-12T21:08:18 < jpa-> and the only reason to buy new phones isn't really just to upgrade one part :)
2013-09-12T21:08:37 < zyp> nah, there's improvements happening all over
2013-09-12T21:08:37 <+Steffanx> No it's because people want the most fanciest phone..
2013-09-12T21:08:50 < jpa-> yep

2013-09-13T00:30:43 < emeb> Very strange - the I2S port on the F303 gets its framing mis-aligned for some reason.
2013-09-13T00:31:25 < emeb> MSB of one sample becomes the LSB of the previous sample, gain changes and signals overflow. very icky.
2013-09-13T00:32:23 < emeb> Can solve by fiddling with the sample rate, or changing the codec initialization sequencing, but can't hit the higher sample rates.

2013-09-13T01:32:08 < emeb> zyp: no, I think its internal clocking.
2013-09-13T01:32:33 < emeb> I did the development for this on my little f303 breakout which has an 8MHz xtal.
2013-09-13T01:33:08 < zyp> ok
2013-09-13T01:33:13 < emeb> the client didn't want an xtal, so we're using the HSI. Unfortuantely, the 8MHz HSI gets divided by 2 into the PLL, so the max freq with the HSI is 64MHz
2013-09-13T01:33:20 < zyp> I had issues with the fifo on F3 SPI at least
2013-09-13T01:33:29 < emeb> interesting
2013-09-13T01:33:46 < zyp> well, before I reworked my code to accord for it
2013-09-13T01:33:50 < emeb> Anyway, I think that my clocks are all messed up due to that extra /2.
2013-09-13T01:34:42 < emeb> so the I2S port main clock input isn't running as fast as it could and the internal timing may get b0rked.

2013-09-13T02:30:33 < gxti> got i2c working well enough for my needs, no repeated start or 10 bit addresses but whatever
2013-09-13T02:31:10 < gxti> i wanted to do repeated start from "userspace" without queueing up multiple operations but apparently the timing of the start is critical
2013-09-13T02:31:45 < zyp> F3 or older?
2013-09-13T02:31:51 < gxti> f1
2013-09-13T02:32:00 < zyp> right
2013-09-13T02:32:35 < zyp> it's not that it's critical, but it's pipelined
2013-09-13T02:32:55 < zyp> you have the same problem with stop
2013-09-13T02:33:05 < zyp> a repeat start is just a start that is sent instead of stop
2013-09-13T02:34:14 < zyp> my code does either a read, a write or a write followed by a read with a repeat start in between
2013-09-13T02:34:53 < gxti> ya, all i have now is 1 master and 1 eeprom and the eeprom doesn't seem to mind a delay between write and read so this is sufficient
2013-09-13T02:34:59 < zyp> http://cgit.jvnv.net/laks/tree/i2c/i2c.cpp <- and the code to support the repeat start is on line 65
2013-09-13T02:36:07 < gxti> neither you nor Laurenceb seem to like using preprocessor macros
2013-09-13T02:36:32 < zyp> for what?
2013-09-13T02:36:45 < gxti> "reg.CR1 |= 0x400; // Set ACK."
2013-09-13T02:37:01 < zyp> if anything I would use an enum, not a macro
2013-09-13T02:37:06 < gxti> vs "reg.CR1 |= I2C_CR1_ACK;"
2013-09-13T02:37:08 < gxti> either way
2013-09-13T02:39:05 < gxti> actually i could made repeated start work just by leaving it hanging *after* the start, not before, but this works well enough
2013-09-13T02:39:25 < zyp> enums for register bits are too low on the list of priorities
2013-09-13T02:39:33 < zyp> and not very useful
2013-09-13T02:41:01 < gxti> and it's improbable that i could disabuse you of that notion so i won't attempt it
2013-09-13T02:42:05 < zyp> I find that time is better spent writing working code behind a nice api, than spending lots of time on the look of that code
2013-09-13T02:42:41 < gxti> well st already wrote the header file full of macros
2013-09-13T02:42:57 < gxti> so that's 90% of the way there...
2013-09-13T02:43:02 < zyp> doesn't help when I'm not using it :p

2013-09-13T08:33:37 < emeb_mac> I got one of those a few months ago
2013-09-13T08:33:40 < emeb_mac> just for giggles
2013-09-13T08:33:55 < GargantuaSauce_> it was certainly a good way to test out my isp / toolchain
2013-09-13T08:34:25 < emeb_mac> mine has a dead pixel

2013-09-13T08:47:01 < R2COM> or define your statement of "seem ok" ?

2013-09-13T08:48:06 < R2COM> who knows whats with next..
2013-09-13T08:48:08 < emeb_mac> There's that

2013-09-13T08:49:26 < emeb_mac> so what did you end up getting?
2013-09-13T08:49:52 < R2COM> I got one batch of cables 3"
2013-09-13T08:50:00 < R2COM> like 50 or so

2013-09-13T08:50:33 < R2COM> but its defined what type of cable it is
2013-09-13T08:50:40 < emeb_mac> indeed
2013-09-13T08:50:43 < emeb_mac> why 90deg?
2013-09-13T08:51:00 < R2COM> thats what I found I didnt find same deal for straight ones
2013-09-13T08:51:07 < emeb_mac> ya
2013-09-13T08:51:10 < R2COM> but for me its ok, since those cables are soft, and can be easily bent
2013-09-13T08:51:13 < emeb_mac> straight is a lot easier to use
2013-09-13T08:51:47 < R2COM> since most of boards I do are either small or designed so that sma is at edge, its not problem
2013-09-13T08:51:57 < R2COM> if both boards have it on top, I just put it above
2013-09-13T08:52:00 < R2COM> if at edge I bent it
2013-09-13T08:52:19 < R2COM> so each comes down to 0.6$
2013-09-13T08:52:31 < emeb_mac> that's reasonable
2013-09-13T08:53:12 < R2COM> I have bunch of hard-bend cables too, straight ones
2013-09-13T08:53:20 < R2COM> those were expencive, 13$ from digikey each
2013-09-13T08:53:38 < emeb_mac> DK RF stuff is not cheap
2013-09-13T08:54:30 < R2COM> and I'm not sure that buying used vna would make sense
2013-09-13T08:54:47 < emeb_mac> depends on how much you'd use it
2013-09-13T08:55:02 < R2COM> I mean..one can buy used and certified one, or sold by reputable used equipment sellers, but then its not cheap anyhow
2013-09-13T08:55:12 < emeb_mac> I've got an ancient HP sweeper and an Agilent spectrum analyzer.

2013-09-13T09:08:26 < emeb_mac> (in bands)
2013-09-13T09:09:26 < R2COM> teflon is hard to produce or..
2013-09-13T09:09:27 < R2COM> hmm
2013-09-13T09:12:20 < R2COM> so its mainly process engineers and chemical people who know how to get that thing done in a shape needed
2013-09-13T09:12:42 < R2COM> but technology is developed anyhow... I guess its just a matter of buying equipment for making teflon PCBs for those companies who sell it
2013-09-13T09:12:54 < R2COM> but once they do it they charge cosmic prices for that
2013-09-13T09:12:58 < emeb_mac> ya
2013-09-13T09:13:16 < R2COM> actually in general it doesnt matter what the material is...
2013-09-13T09:13:17 < R2COM> heh..
2013-09-13T09:13:18 < emeb_mac> I think the place I worked they did their own duroid boards
2013-09-13T09:13:45 < R2COM> well I guess the main thing here is: making sure that er and loss ar constant over high frequency range
2013-09-13T09:14:26 < R2COM> so if someone comes up with some material "X" which has er=2:10, and small loss up to 20GHz then its ok...
2013-09-13T09:14:36 < GargantuaSauce_> i wonder what adhesive they use for the copper on teflon PCBs
2013-09-13T09:14:43 < R2COM> its just I am thinking now... that there are probably not so many materials available with such properties
2013-09-13T09:14:59 < R2COM> and + being able to realize small design rules and make pcb out of it :)
2013-09-13T09:15:18 < emeb_mac> GargantuaSauce_: ya - and the copper doesn't stick well to the teflon.
2013-09-13T09:15:39 < GargantuaSauce_> yeah definitely can't see that being easy to do
2013-09-13T09:15:50 < emeb_mac> I was working with some GHz power amps a while back where someone had banged a bias pot and peeled it right off.

2013-09-13T09:18:35 < R2COM> which ...lots of them can be done on a way cheaper materials too ;)
2013-09-13T09:19:00 < emeb_mac> right - any high volume / cost sensitive applications get designed on more common materials
2013-09-13T09:19:42 < emeb_mac> throw enough power at it and you can use cheap PCBs
2013-09-13T09:20:00 < emeb_mac> or just live with crappy performance
2013-09-13T09:20:07 < R2COM> cheap PCBs wont handle big power too...
2013-09-13T09:21:29 < R2COM> I'm trying to think if its doable to make something like that at "home" conditions
2013-09-13T09:21:58 < R2COM> I mean...find some material which is easy to make at least simple PCB of
2013-09-13T09:22:11 < R2COM> which has constant dielectric and low loss on big range...
2013-09-13T09:23:17 < R2COM> or just buy those from chinese ;)

2013-09-13T09:24:28 < R2COM> lol
2013-09-13T09:24:33 < emeb_mac> wonder what they charge
2013-09-13T09:24:40 < emeb_mac> seems like a fairly small amount
2013-09-13T09:25:10 < R2COM> yeah I guess
2013-09-13T09:25:48 < R2COM> I mean from a technological point of view making materials like that is not big deal
2013-09-13T09:26:05 < R2COM> its just US suppliers of this stuff make big shit out of it by putting F16 pics on their websites
2013-09-13T09:26:09 < R2COM> and charge $$$
2013-09-13T09:26:20 < emeb_mac> probably is a big deal if you want highly controlled RF specs
2013-09-13T09:26:52 < R2COM> not that big of a deal
2013-09-13T09:27:03 < R2COM> I mean come on, its not a rocket engine or stuff like that
2013-09-13T09:27:41 < emeb_mac> even small things can be hard to make.
2013-09-13T09:27:52 < emeb_mac> make well at least
2013-09-13T09:28:19 < R2COM> I'm saying that technologically its not something extra high tech

2013-09-13T09:39:37 < R2COM> the bigger challenge I guess is to make own custom device working on higher frequencies on pcb
2013-09-13T09:40:03 < R2COM> even with rf transistors with high ft the parasitics add up so much

2013-09-13T09:45:41 < R2COM> before doing that one needs to do it himself and test device

2013-09-13T19:06:21 < Laurenceb> lens is now mounted 1cm inside their hand...
2013-09-13T19:07:03 < Laurenceb> luckily i dont have to fill out health and safety stuff
2013-09-13T19:07:54 < Laurenceb> theres still blood over the floor :-/

2013-09-14T03:36:51 < emeb> not bad.
2013-09-14T03:37:09 < R2COM> not sure, I expected less reflection at higher frequencies from rg223
2013-09-14T03:37:14 < emeb> OK out to 16GHz
2013-09-14T03:37:23 < R2COM> if I am correct they should be good for about to 20GHz
2013-09-14T03:38:09 < emeb> about 6dB ripples out at 17-20
2013-09-14T03:41:15 < englishman> what was the cost? ~3-4?
2013-09-14T03:41:51 < R2COM> 29$ for pack of 50

2013-09-14T03:45:06 < R2COM> when I get time I need to research better launch design for thru headers for RF connector
2013-09-14T03:45:20 < R2COM> because those are cheap
2013-09-14T03:45:40 < emeb> yeah - when you're working up at those freqs, doesn't take much.
2013-09-14T03:45:58 < R2COM> actually current stuff I work is <3GHz
2013-09-14T03:46:07 < emeb> little impedance discontinuity and *boom*
2013-09-14T03:46:19 < R2COM> yeah, for high freq
2013-09-14T03:46:25 < emeb> right - you're fine at 3.
2013-09-14T03:47:02 < R2COM> the thing is, with 6.7mils prepreg, er=3.66 I get 12mil trace.. and kinda more room under thru thru. SMA to do stuff in a right way
2013-09-14T03:47:12 < R2COM> what I mean is trace is thin enough
2013-09-14T03:47:57 < R2COM> I am assuming one of the problems is the fact that, for example if I route just on top layer, right after SMA connector, theres that SMA pin stub going all the way down
2013-09-14T03:48:07 < R2COM> and I assume it degrades things
2013-09-14T03:48:24 < R2COM> but.. one needs it since it has to be soldered from backside of pcb
2013-09-14T03:49:10 < R2COM> and that stub, is.. like via but at the same time not via too..
2013-09-14T03:50:09 < R2COM> I guess it needs some detailed 3D simulation with different reference plane arrangements, and basically figure out what is the best way to compensate for that by appropriately arranging reference planec around it
2013-09-14T03:50:23 < R2COM> its just a bit tedious work

2013-09-14T05:16:40 < gxti> the trick is to DC-connect them without passing data, so it can still see the resistors that say it's ok to use max current

2013-09-15T00:31:29 < Laurenceb_> truly epic lulz
2013-09-15T00:33:04 < emeb> STM32F405-based audio effects I did some work on: http://www.analoguehaven.com/audiodamage/
2013-09-15T00:34:08 < gxti> emeb: what's the sample rate and bit depth?
2013-09-15T00:34:23 < emeb> gxti: 48kHz 16-bit
2013-09-15T00:34:56 < emeb> it could go to 96/24, but that's not very useful for this market.
2013-09-15T00:35:24 < gxti> yeah, was thinking about doing mixing in software but even if the cpu could handle it there's still the matter of getting all the streams in to begin with
2013-09-15T00:35:25 < Robint91> emeb, did you wrote your own DSP functions or used ARMs
2013-09-15T00:35:44 < Robint91> mhh
2013-09-15T00:35:47 < emeb> fwiw - I just did the board design. these guys are FX pros and do all their own dsp
2013-09-15T00:35:48 < gxti> will probably end up doing it analog, or maybe fpga if i'm bored
2013-09-15T00:36:10 < Robint91> digital mixing requires dithering
2013-09-15T00:36:17 < Robint91> emeb, oh
2013-09-15T00:36:21 < emeb> I showed 'em how to get the MCU started up, get the codec running and then they took it from there.
2013-09-15T00:37:21 < emeb> Robint91: I do DSP software for other folks though. I've used some of the routines in CMSIS, but usually write my own.
2013-09-15T00:37:37 < Robint91> emeb, ASM or just normal C
2013-09-15T00:37:39 < Laurenceb_> but its not analogue
2013-09-15T00:38:12 < emeb> Robint91: Usually normal C code. GCC is great for optimizing performance for speed and I haven't been able to beat it with assy.
2013-09-15T00:38:44 < Robint91> I don't know if GCC even uses the DSP instructions (if you are working with fixed point arth)
2013-09-15T00:38:51 < Robint91> but for float gcc is good
2013-09-15T00:39:21 < emeb> Robint91: latest GCC is aware of the M4 DSP instructions. Not sure how well it uses them tho.
2013-09-15T00:39:30 < emeb> It can use the saturation instr though.

2013-09-15T01:10:58 < gxti> because f4 is known for its microamp consumption
2013-09-15T01:11:17 < emeb> har
2013-09-15T01:11:28 < ds2> emeb: all good ARM projects should be battery powered :D
2013-09-15T01:11:48 < emeb> Sadness - these must not be good ARM projects.
2013-09-15T01:12:13 < emeb> they pull about +12V / 60ma and -12V / 5ma
2013-09-15T01:12:28 < emeb> which is not out of line for this type of product.
2013-09-15T01:12:49 < ds2> is that for the F4 or the analog audio stuff?
2013-09-15T01:13:42 < emeb> These are Modular Synthesizer modules. They go in a 19" rack with +/-12V supplies already provided.

2013-09-15T01:14:14 < emeb> The signal I/O levels are typically in the +/-10V range, so the 12V supply is mainly to power the analog I/O buffers
2013-09-15T01:14:34 < emeb> the STM32 is running off an LDO that drops 12V down to 3.3V.

2013-09-15T01:17:08 < emeb> Yeah - not what I would have done ideally.
2013-09-15T01:20:56 < Laurenceb_> you know that the stm32 core runs at 1.2v ...
2013-09-15T01:21:02 < Laurenceb_> well on F4 it does
2013-09-15T01:21:11 < emeb> yes, I do.
2013-09-15T01:21:25 < Laurenceb_> 10% XD
2013-09-15T01:22:01 < emeb> excluding I/O and the codec that runs at 3.3V, so 10% + epsilon.

2013-09-15T05:34:15 < zyp> gxti, did you try newlib-nano?
2013-09-15T05:34:28 < zyp> you have to select it explicitly with --specs=nano.specs
2013-09-15T05:35:06 < zyp> also, -O3 is not supposed to be small, -O2 is usually smaller
2013-09-15T05:35:20 < zyp> (and -Os even more so)
2013-09-15T05:36:01 < gxti> i have plenty of room, just trying to figure out where 30% more crap came from even with the same options
2013-09-15T05:37:37 < zyp> more inlining, loop unrolling, etc

2013-09-15T05:37:47 < dongs> he said "same options"
2013-09-15T05:37:48 < zyp> i.e. duplicating code to avoid branches
2013-09-15T05:37:51 < zyp> ah
2013-09-15T05:38:10 < gxti> i've always used -O3 for this project because it makes a noticeable improvement to latency

2013-09-15T05:50:02 < gxti> zyp: nano.specs is nice, just as small as chprintf (crappy chibios implementation i had before)
2013-09-15T05:50:38 < zyp> nano also strips float support by default
2013-09-15T05:50:47 < zyp> readme says how you add it back in if you need it
2013-09-15T05:50:58 < zyp> just so you're aware of it
2013-09-15T05:51:23 < gxti> uh, i use soft float and it seems to still be working
2013-09-15T05:54:48 < zyp> I mean float formatting in printf
2013-09-15T05:55:06 < gxti> ah yeah, i can live without that. i don't think it was working anyway.
2013-09-15T05:55:18 < zyp> with TNT?
2013-09-15T05:55:25 < gxti> that was TNT yes, didn't think to try GAE
2013-09-15T05:55:29 < zyp> if so, that might be what was adding the extra code
2013-09-15T05:55:46 < gxti> because of a format string? how would that even work?
2013-09-15T05:55:48 < zyp> because in GAE it should be working perfectly
2013-09-15T05:55:56 < zyp> huh?
2013-09-15T05:56:37 < zyp> printf doesn't know at compile time what kind of format characters you're using, so it has to include the code for anything you might happen to throw at it
2013-09-15T05:57:06 < zyp> even if you're not printing floats, you might, and therefore they have to be handled
2013-09-15T05:57:12 < gxti> right
2013-09-15T05:57:19 < zyp> unless the code is modified to not do it, as nano-specs does
2013-09-15T05:57:30 < gxti> so is TNT using nano, just with the float suport then?
2013-09-15T05:58:19 < zyp> dunno
2013-09-15T05:58:48 < zyp> I tend to not care much about newlib, I'm not really using libc in my own stuff :p
2013-09-15T05:59:12 < zyp> the only part of libc I'm using currently is stdint.h, and that's just type definitions :p
2013-09-15T05:59:19 < gxti> printf is nice though
2013-09-15T05:59:26 < gxti> especially since this has a uart cmdline
2013-09-15T05:59:33 < gxti> plus eventually will do syslog
2013-09-15T05:59:36 < zyp> sure
2013-09-15T05:59:45 < zyp> I just do rblog
2013-09-15T05:59:56 < zyp> has taken care of all my printing needs so far
2013-09-15T06:03:07 < gxti> looks like with this latest implementation, the latency change from Os to O3 is less than 5uS
2013-09-15T06:03:52 < gxti> i probably made that determination when i was first getting this project running, and forgot i had left chibios' debug shit all turned on
2013-09-15T06:04:22 < zyp> so, to summarize, GAE with newlib-nano gives you the best numbers you've measured so far?
2013-09-15T06:04:35 < gxti> couldn't figure out why i was getting so much worse pings than qyx_ who had the same hardware setup, that was why
2013-09-15T06:05:48 < gxti> zyp: for this implementation GAE+nano has the smallest code. the old implementation not using libc is smaller when built with TNT.
2013-09-15T06:06:06 < gxti> so if i can get the nano libc into tnt that should be better still
2013-09-15T06:06:54 < zyp> hmm, is the latter true for all optimization levels? and how does that effect the actual performance?
2013-09-15T06:07:25 < zyp> again, a newer compiler providing larger code sounds like more aggressive optimization to me
2013-09-15T06:07:49 < gxti> it's not the same code, tnt has a different libc
2013-09-15T06:07:53 < zyp> especially since you're testing at -O3
2013-09-15T06:08:19 < gxti> and performance is not libc-related at all, it's just one call per second or so
2013-09-15T06:08:20 < zyp> you were talking about some old implementation not using libc
2013-09-15T06:08:34 < zyp> performance is optimization related :p
2013-09-15T06:09:49 < gxti> there's no measurable performance difference between GAE and TNT with the same -O level. each is a few microseconds faster at -O3 than at -Os, much less than was the case when i originally chose to use -O3.
2013-09-15T06:10:03 < gxti> i will probably switch to -Os
2013-09-15T06:12:24 < gxti> and TNT has considerably better code size at all optimization levels after libc is removed from the equation
2013-09-15T06:12:55 < zyp> hmm, that's interesting
2013-09-15T06:13:11 < gxti> the TNT changelog shows that less than a month after i built my TNT chain it switched from newlib to newlib-nano
2013-09-15T06:13:11 < zyp> what gcc version is your TNT based on?
2013-09-15T06:13:25 < GargantuaSauce_> supposedly arm gcc 4.7 has a better libc
2013-09-15T06:13:27 < gxti> so i'll go rebuild it and probably everything will be fantastic afterwards
2013-09-15T06:14:14 < gxti> GAE is 4.7.3, TNT is 4.7.2. both built around the same time as well.
2013-09-15T06:14:52 < GargantuaSauce_> maybe it was 4.8 or maybe i'm full of shit

2013-09-15T09:00:37 < GargantuaSauce_> i am banging together a shitty serial<->nrf24l01 bridge with an atmega8
2013-09-15T09:00:53 < emeb_mac> ewww... AVR
2013-09-15T09:00:58 < GargantuaSauce_> yeah
2013-09-15T09:01:07 < gxti> latest TNT built with NANO=true, down to 52160. it comes with a nano.specs but when i try to use it i get "cannot find -lc_s", probably not necessary
2013-09-15T09:02:09 < emeb_mac> so, debugging some GPIO on F303. I set the pin type/direction/etc and drive it low/high. later when I try to toggle the pin it doesn't change state. Any idea why?
2013-09-15T09:02:36 < GargantuaSauce_> bus clock enabled?
2013-09-15T09:02:52 < emeb_mac> well, clocks were enabled for the initial setup & state.
2013-09-15T09:03:05 < emeb_mac> looking thru the code I don't see the clocks disabled after that.

2013-09-15T20:35:15 < Laurenceb_> and is CE approved
2013-09-15T20:35:15 < dongs> By copying the same time.txt file into multiple loggers and pressing the button on all loggers at exactly the same time the loggers can be synchronized. The only synchronization error is due to the difference in time of the button presses.
2013-09-15T20:35:24 < Laurenceb_> wait...

2013-09-15T21:56:49 < gxti> Tectu: lwip works great, it's the binding between lwip and the hardware that needs improvement and that has nothing to do with lwip
2013-09-15T21:57:22 < jpa-> it's funny how on F4, most people are moving towards the "copy to DMA buffer" approach, in order to be able to make use of CCM
2013-09-15T21:57:27 < gxti> lwip has pbufs which let you chain together hunks of memory, so i could for example have a big pool some of which is assigned to DMA for inbound packets
2013-09-15T21:57:43 < gxti> when a packet comes in, instead of copying i just give it directly to lwip
2013-09-15T21:58:29 < gxti> that's the theory anyway, actually implementing it will be a bit of work and i understand why the chibios bindings do not do that

2013-09-15T23:06:37 < zyp> but it doesn't do much yet
2013-09-15T23:07:16 < mtbg> so the ethernet peripheral is that simple?
2013-09-15T23:07:38 < zyp> sure
2013-09-15T23:07:41 < jpa-> only when zyp does it

2013-09-15T23:10:36 < mtbg> btw zyp, I have finally managed to configure the usb hs to use internal dma, but I'm quite disappointed about the reference manual, it sometimes is contrary with the st usb library and also you have to use the peripheral in somewhat different way that it states to get it working
2013-09-15T23:11:06 < zyp> ok
2013-09-15T23:11:13 < zyp> I haven't done DMA
2013-09-15T23:11:20 < jpa-> "On Februare 15, 2014, the Cassiope Mishap Investigation Board released a Phase I report, detailing the suspected issues involving lack of adequate separator characters in computer instructions causing the complete loss of the spacecraft."
2013-09-15T23:11:52 < qyx_> report from the future?
2013-09-15T23:12:04 < jpa-> i can see it coming
2013-09-15T23:13:04 < mtbg> zyp: it is worth using, you get over 34MB/s (M as in 10^6) with zero cpu load and you can configure a transfer of the size bigger than the fifo available space and that dma engine will still handle it properly
2013-09-15T23:13:09 < zyp> I might add DMA support to my USB code after I'm done with the API cleanup
2013-09-15T23:14:11 < mtbg> maximum is 4096 bytes for a single dma transfer since you can't have more than 8 packets configured in D{O,I}EPTSIZn
2013-09-15T23:14:32 < zyp> currently my stack doesn't operate with transactions, only packets, so that's what I'm planning to add

2013-09-15T23:52:54 < mtbg> it does from ~300 up to 1100nm afair
2013-09-15T23:52:58 < emeb_mac> useful for astronomy?

2013-09-16T00:47:58 <@Tectu> dongs, are you there?
2013-09-16T00:48:22 < emeb_mac> likely dongs is in dreamland
2013-09-16T00:48:43 <@Tectu> I really wonder what dongs dreams about
2013-09-16T00:49:17 <+Steffanx> No, he wants you to believe he is human.. so he says he goes to bed
2013-09-16T00:49:36 < talsit> Tectu: it's not even 7am yet in japan
2013-09-16T00:49:53 <+Steffanx> He is obviously just a robot with limited response capabilities
2013-09-16T00:50:02 <+Steffanx> When it gets too difficult he just does not reply.
2013-09-16T00:50:06 <@Tectu> talsit, indeed, I didn't think of that but "weird people" are used to be up on weird times
2013-09-16T00:50:56 <+Steffanx> and my Tectu is still awake?
2013-09-16T00:51:09 <@Tectu> yes, watching a movie
2013-09-16T00:51:22 <@Tectu> 30 more minutes, then public and private tectu is in dream land too
2013-09-16T00:51:26 <+Steffanx> which one?
2013-09-16T00:51:53 <@Tectu> Franklyn (2008)
2013-09-16T00:52:02 <+Steffanx> heh, me too!
2013-09-16T00:52:14 <@Tectu> hum? seriously?
2013-09-16T00:53:21 <+Steffanx> im always seriouos
2013-09-16T00:53:29 < emeb_mac> you guys are scary
2013-09-16T00:54:13 <@Tectu> Steffanx, what's the hair color of the main character=
2013-09-16T00:54:49 <+Steffanx> Im not sure who the main character is. The current 'main character' wears a mask-ish thing.
2013-09-16T00:55:15 <@Tectu> you're really watching the same movie o.O
2013-09-16T00:56:04 < zyp> same channel? :p
2013-09-16T00:56:09 <+Steffanx> You are here for a reason not emeb_mac?
2013-09-16T00:56:18 <+Steffanx> We don't share TV channels..
2013-09-16T00:56:27 <+Steffanx> except for bbc and some german crap maybe
2013-09-16T00:56:28 <@Tectu> also I'm watching it off my HDD
2013-09-16T00:56:35 <@Tectu> I don't even own a TV
2013-09-16T00:56:42 < zyp> heh
2013-09-16T00:59:42 < emeb_mac> what is a tv these days anyway?
2013-09-16T00:59:54 < emeb_mac> just a big-ass monitor with a demod as one input option.
2013-09-16T01:00:12 <+Steffanx> A commercial box.
2013-09-16T01:00:35 <+Steffanx> Who should get paid to watch it.
2013-09-16T01:00:38 < emeb_mac> a pc w/ internet and no adblock is too.
2013-09-16T01:01:37 <@Tectu> emeb_mac, aren't you in the age-range of TV-people?
2013-09-16T01:01:59 <+Steffanx> He is probably still into black and white TV
2013-09-16T01:02:21 < emeb_mac> define the age-range of tv people
2013-09-16T01:02:26 <+Steffanx> without a remote
2013-09-16T01:02:27 <@Tectu> not sure if licenses are good for colors, eh?
2013-09-16T01:03:34 <@Tectu> emeb_mac, well, you grew up without TV, and then you got one, and then you stick to it and everything new is just faggotry?
2013-09-16T01:04:07 < emeb_mac> eh. not quite that old
2013-09-16T01:04:12 < mtbg> zyp: what is the laks btw, just a set of functions for hardware abstraction or an OS?
2013-09-16T01:04:24 <@Tectu> emeb_mac, but >40, no? :x
2013-09-16T01:05:08 < zyp> mtbg, depends on where you draw the line
2013-09-16T01:05:30 <@Tectu> ^ typical answer of a smart person
2013-09-16T01:05:34 < emeb_mac> Tectu: a bit.
2013-09-16T01:05:35 < mtbg> does it do context switching?
2013-09-16T01:05:38 < zyp> yes
2013-09-16T01:05:46 <@Tectu> emeb_mac, I hope you don't mind...
2013-09-16T01:06:27 < emeb_mac> Tectu: you don't get this old w/o picking up a sense of humor along the way. :)
2013-09-16T01:06:32 <+Steffanx> " everything new is just faggotry" he has a mac and uses stm32 .. Tectu
2013-09-16T01:06:44 < zyp> currently it only does cooperative multitasking in a round-robin fashion, without any notion of threads being ready to run or not
2013-09-16T01:06:49 <@Tectu> emeb_mac, good :)
2013-09-16T01:06:56 <@Tectu> Steffanx, doesn't mean he likes it ;)
2013-09-16T01:07:09 < zyp> but I have some improvements to that in the works, that would make it look more like a little OS
2013-09-16T01:07:13 < emeb_mac> Steffanx: but no smartphone yet. Just a sammy android tablet.
2013-09-16T01:07:18 < mtbg> ok
2013-09-16T01:07:19 < mtbg> btw
2013-09-16T01:07:32 <+Steffanx> but im not into smart phones either emeb_mac, does that make me old?
2013-09-16T01:07:39 < emeb_mac> probably.
2013-09-16T01:07:39 < zyp> and then I might make the entire multithreading optional, since I'm doing a bunch of projects that doesn't have more than one thread anyway
2013-09-16T01:07:41 <@Tectu> no, just sane
2013-09-16T01:07:49 <@Tectu> and potentially associal
2013-09-16T01:07:53 <@Tectu> asocial*
2013-09-16T01:07:55 <+Steffanx> i dont care at all :P
2013-09-16T01:07:57 < emeb_mac> flipside - my parents have smartphones.
2013-09-16T01:08:13 <@Tectu> then probably also a bit rebelic
2013-09-16T01:08:13 < emeb_mac> does that make them not-old?
2013-09-16T01:08:26 <+Steffanx> To my standards smart phones make yo more asocial.
2013-09-16T01:08:27 < zyp> emeb_mac, you're so old that they probably went full circle and became young again? :p
2013-09-16T01:08:41 <@Tectu> yes emeb_mac, you crossed the line, you passed the serenity: your parents are younger than you :P
2013-09-16T01:08:43 < emeb_mac> it's like two's-complement overflow.

2013-09-16T01:10:19 <@Tectu> "reached the singularity", I wanted to say

2013-09-16T01:25:24 < Laurenceb_> whats the file format?
2013-09-16T01:25:59 < gxti> elf
2013-09-16T01:26:52 < gxti> sort of like it just poops the program back out, but with runtime data (and usually not the text since it assumes you already have it)
2013-09-16T01:27:11 < Laurenceb_> ah
2013-09-16T01:27:18 < Laurenceb_> hmm sounds a little complex
2013-09-16T01:27:27 < Laurenceb_> has anyone written a nice library for this?
2013-09-16T01:27:34 < gxti> not for microcontrollers
2013-09-16T01:27:39 < gxti> at least i doubt it
2013-09-16T01:28:00 < mtbg> isn
2013-09-16T01:28:16 < mtbg> isn't gdb able to do such a dump via a debug interface?
2013-09-16T01:28:31 < gxti> depends on the adapter but yeah
2013-09-16T01:28:56 < gxti> i'm thinking about something that would run in the field though, not sure how practical it is
2013-09-16T01:29:17 < gxti> autonomously detect a fault condition, dump core to sd, reset
2013-09-16T01:30:03 < mtbg> you could just dump the whole ram and the registers to a file in arbitrary format
2013-09-16T01:30:32 < mtbg> and then possibly generate a core file out of it on pc
2013-09-16T01:30:43 < gxti> sure, the file format isn't the interesting part. although now it's got me thinking about an elf bootloader.
2013-09-16T01:31:36 < gxti> i was thinking something nutty with relocations, but probably simpler to just move my bootloader to the end of flash and then i don't need it :p
2013-09-16T01:35:37 < emeb> oh here's a good one: I've got one of those cheap saelae logic analyzers hooked up to my f303 project to debug some gpio stuff.
2013-09-16T01:36:25 < emeb> it keeps the SWD from programming correctly if you don't start the windows software first.
2013-09-16T01:37:01 < emeb> default pin configuration of the cypress usb chip must load the inputs down or something
2013-09-16T01:37:04 < gxti> those use the cypress usb thingies that always load code from the host right?
2013-09-16T01:37:11 < emeb> yeah
2013-09-16T01:37:18 < GargantuaSauce_> a LA that drives its inputs
2013-09-16T01:37:20 < GargantuaSauce_> oh joy
2013-09-16T01:37:20 < gxti> maybe there are some buffers that aren't being pulled safely during reset

2013-09-16T06:20:22 < R2COM1> hey one question here, if I buy a Tablet that runs Win8, does it mean that all the Desktop applications I developed with Visual Studio for Win will run there too?
2013-09-16T06:22:02 < GargantuaSauce_> no
2013-09-16T06:22:20 < GargantuaSauce_> well, .net ones perhaps i am not 100% sure
2013-09-16T06:22:51 < GargantuaSauce_> but (assuming you're talking about an arm tablet) not native ones
2013-09-16T06:23:27 < R2COM1> i aksed this question already on csharp now
2013-09-16T06:23:31 < R2COM1> actually
2013-09-16T06:23:35 < R2COM1> it wont run on Win8 RT
2013-09-16T06:23:37 < R2COM1> the arm ones
2013-09-16T06:24:13 < R2COM1> so if tablet runs Win8 legit one, like x86 or x86_64
2013-09-16T06:24:15 < R2COM1> it should work
2013-09-16T06:24:29 < GargantuaSauce_> yes
2013-09-16T06:24:34 < R2COM1> I noticed those tablets with WIn8 are like 800$ for one with 64 bit, and ~400$ for 32bit processors
2013-09-16T06:24:45 < GargantuaSauce_> wtf do the 32 bit ones have
2013-09-16T06:24:47 < GargantuaSauce_> 1st-gen atoms??
2013-09-16T06:25:00 < GargantuaSauce_> everything since that has 64 bit support i think?
2013-09-16T06:25:35 < R2COM1> http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=7352778&CatId=6845
2013-09-16T06:26:05 < R2COM1> not sure if it makes sense to buy those for 500$ ? or add 300$ and buy x64 version for 800$
2013-09-16T06:27:17 < R2COM1> http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=4977883&CatId=6845
2013-09-16T06:27:52 < R2COM1> I am thinking to get one later
2013-09-16T06:28:10 < R2COM1> convenient to work in a field with custom hardware, and run my application which talks to it
2013-09-16T06:28:17 < R2COM1> since it seems less than average laptop
2013-09-16T06:28:52 < GargantuaSauce_> i cant believe intel made another line of 32 bit atoms
2013-09-16T06:29:05 < GargantuaSauce_> it's probably a piece of shit, find something with an i3 or i5
2013-09-16T06:29:29 < R2COM1> i5?
2013-09-16T06:29:31 < R2COM1> 32bit?
2013-09-16T06:29:40 < GargantuaSauce_> uh 64
2013-09-16T06:30:05 < R2COM1> here http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=2259113&CatId=6838
2013-09-16T06:30:11 < R2COM1> but this shit is just another laptop now!
2013-09-16T06:30:17 < R2COM1> big! and with keayboard
2013-09-16T06:30:44 < R2COM1> oh
2013-09-16T06:30:45 < R2COM1> here

2013-09-16T06:30:48 < R2COM1> 1300$
2013-09-16T06:31:00 < R2COM1> i5
2013-09-16T06:31:07 < GargantuaSauce_> that is probably what i would go for
2013-09-16T06:31:10 < GargantuaSauce_> your money though dude
2013-09-16T06:32:25 < R2COM1> 4GB ddr3
2013-09-16T06:32:29 < R2COM1> and 64GB SSD
2013-09-16T06:32:48 < GargantuaSauce_> i can't imagine using a machine with less than 4 gigs of ram these days
2013-09-16T06:32:55 < GargantuaSauce_> nothing i own has less than 8
2013-09-16T06:33:10 < R2COM1> it doesnt say how many cores it has
2013-09-16T06:33:13 < R2COM1> i5?
2013-09-16T06:33:16 < R2COM1> 4 cores?
2013-09-16T06:33:35 < GargantuaSauce_> 2 with ht
2013-09-16T06:33:43 < R2COM1> ht = ?
2013-09-16T06:33:53 < GargantuaSauce_> hyperthreading
2013-09-16T06:34:47 < R2COM1> that tablet looks hot
2013-09-16T06:34:56 < R2COM1> heh I got my Desktop for that price
2013-09-16T06:35:03 < R2COM1> with ADM though..
2013-09-16T06:35:06 < R2COM1> AMD
2013-09-16T06:35:25 < R2COM1> heh its processors on that tablet is 1.33GHz...
2013-09-16T06:35:27 < R2COM1> hmmm
2013-09-16T06:36:04 < R2COM1> doesnt sound like a lot...
2013-09-16T06:39:04 < GargantuaSauce_> well I guarantee that sandy bridge i5 at 1.3 outperforms the atom at 1.5

2013-09-16T08:46:48 < dongs> im awesome liek that
2013-09-16T08:47:20 < emeb_mac> so kawaii
2013-09-16T08:49:34 < R2COM> best moment to take of pcb, - "taking it out of drivers window"
2013-09-16T08:49:47 < R2COM> to take picture of pcb I mean
2013-09-16T08:51:20 < dongs> yes.
2013-09-16T08:52:29 < R2COM> but its ok I did worse things while driving
2013-09-16T08:54:19 < emeb_mac> texting
2013-09-16T08:55:56 < R2COM> nah.
2013-09-16T08:56:46 < emeb_mac> pcb layout while driving
2013-09-16T08:58:08 < R2COM> no
2013-09-16T08:59:36 < dongs> you do that on your jewpad retina
2013-09-16T09:00:11 < R2COM> not sure what two last words mean
2013-09-16T09:01:40 < dongs> http://images.anandtech.com/doci/5663/lepixel2.jpg
2013-09-16T09:03:09 < R2COM> strange, I am looking at one crystal oscillator from Velpay, which used on analog devices ADC board, its powered with 3.3V but generates -4:+4v sinusoid
2013-09-16T09:03:23 < R2COM> not sure if amplitude is supposed to be that way
2013-09-16T09:03:25 < dongs> flux capacitor
2013-09-16T09:03:35 < R2COM> what?
2013-09-16T09:04:39 < R2COM> at the beginning I was like, wtf, ADC clock input might get fucked
2013-09-16T09:05:06 < R2COM> but then I constructed front end of ADC board in simulator, and runned transient analysis, with added equivalent circuit from ADC datasheet
2013-09-16T09:05:16 < R2COM> and pin voltage was within allowable max value
2013-09-16T09:05:38 < R2COM> but still strange why crystal oscillator would give that amplitude
2013-09-16T09:06:05 < R2COM> usually its supposed to be less, because once you add scope probe (cable + scope capacitance) you load it, it should degrade
2013-09-16T09:06:17 < R2COM> and that datasheet of crystal oscillator was not much descriptive
2013-09-16T09:06:25 < R2COM> actually that part is obsolete too
2013-09-16T09:06:55 < R2COM> fucking faggots always use weird components
2013-09-16T09:08:52 < emeb_mac> does it have some sort of resonant LC tank on the output?
2013-09-16T09:09:07 < R2COM> no, just cap for ac coupling on output
2013-09-16T09:09:14 < emeb_mac> maybe internal?
2013-09-16T09:09:59 < R2COM> output goes to 0.1uF cap, then another 0.1uF cap in series (because they used same PCB line for possible SMA connection for clock as well as this crystal osc)
2013-09-16T09:10:17 < R2COM> and after that it goes to input of transformer etc etc
2013-09-16T09:10:38 < emeb_mac> which ADI converter is it?
2013-09-16T09:10:45 < R2COM> ad9253
2013-09-16T09:11:10 < R2COM> they shared PCB line for both SMA jack and Crystal_OSC
2013-09-16T09:12:01 < R2COM> I usually dont like to do these kinds of things
2013-09-16T09:12:56 < emeb_mac> kinda ugly
2013-09-16T09:12:57 < R2COM> although, it might be not *that* bad, because if user wants to use SMA,  then between SMA and series 0.1uF cap, another 0.1uF cap's end going to output of crystal oscillator...not GND... so its not much of parasitics
2013-09-16T09:13:31 < R2COM> they even wrote in recomendation, that if one wants use SMA for clocking, remove that cap coming from Crystal OSC.
2013-09-16T09:13:48 < R2COM> but real question is, why -4 to 4V output measured at that point
2013-09-16T09:14:11 < R2COM> because now I havent removeed any capacitor, and I just used SMA jack for clock input to measure clock output of Crystal OSC
2013-09-16T09:14:19 < R2COM> just for curiosity
2013-09-16T09:16:22 < R2COM> so: SMA---->Node A,    and one 0.1uF cap connected between Node A and output of Crystal_OSC, another 0.1uF cap connected between Node A and 0Ohm resistor and goes in the frontend (XFRMR etc)
2013-09-16T09:16:58 < R2COM> I will remove cap going from Crystal_OSC before using the SMA for clocking, but for now, I havent done that, I used Crystal_OSC< but I used SMA to monitor its signal
2013-09-16T09:17:29 < dongs> welp im out of expensive paste
2013-09-16T09:17:41 < dongs> next dilemma is buy it again in syringe for $$$ or jar for $
2013-09-16T09:17:46 < dongs> talsit: how the fuck do y ou put unused trash back into jar
2013-09-16T09:17:49 < dongs> wihtout aidsing it up
2013-09-16T09:18:36 < talsit> i don't
2013-09-16T09:18:40 < R2COM> I do
2013-09-16T09:18:48 < R2COM> its very simple
2013-09-16T09:18:52 < R2COM> you just puttingit back
2013-09-16T09:21:17 < emeb_mac> used paste = aids?
2013-09-16T09:21:57 < R2COM> no.
2013-09-16T09:22:10 < R2COM> anyhow
2013-09-16T09:22:20 < R2COM> I'v worked with bunch of oscillators of that sort
2013-09-16T09:22:34 < R2COM> and their output is kinda closer to what they are powered with
2013-09-16T09:22:49 < R2COM> it gets degraded though when you load it with scope probes
2013-09-16T09:23:01 < R2COM> but here... it gives -4V to +4V sinusoid
2013-09-16T09:23:09 < R2COM> while powered with 3.3V
2013-09-16T09:23:34 < dongs> R2COM: do you have a spice model for tek P6139a probes
2013-09-16T09:23:53 < R2COM> no
2013-09-16T09:24:01 < R2COM> why
2013-09-16T09:24:25 < dongs> how do  y ou model scope loading a crystal then
2013-09-16T09:24:42 < R2COM> did I say that I modeled scope loading?
2013-09-16T09:25:12 < dongs>         no im asking in general if you had to
2013-09-16T09:25:27 < R2COM> I would have to think about it
2013-09-16T09:25:59 < talsit> solder paste is cheap anyway
2013-09-16T09:26:11 < R2COM> for starters: read its capacitance if stated, its impedance, what type of cable it is, then go see what are parameters for transmission line for that type of cable, and just model T-line + passives
2013-09-16T09:26:19 < R2COM> but its first crude approach just out of my head
2013-09-16T09:28:09 < R2COM> then I would go and download this: http://circuitslab.case.edu/manuals/Probe_Fundamentals-_Tektronix.pdf
2013-09-16T09:28:24 < R2COM> then look at page 7. Figure 1-4A
2013-09-16T09:29:19 < dongs> cool

2013-09-16T10:22:40 < jpa-> yes
2013-09-16T10:23:33 < jpa-> though i wonder if they are in permanent orbit or fall down in a few years
2013-09-16T10:24:33 < Thorn> I sure hope it's no more than a few months
2013-09-16T10:25:06 < jpa-> it's in the faq yeah
2013-09-16T10:25:17 < jpa-> a few months in worst case, probably less
2013-09-16T10:26:40 < Thorn> hopefully nobody would actually agree to launch this thing otherwise
2013-09-16T10:27:11 < Thorn> I wonder why nobody is seeking funds for an amateur radio relay satellite
2013-09-16T10:27:19 < jpa-> china blows up satellites just for fun, what is a hundred small pcb's in a small bunch compared to that?
2013-09-16T10:27:57 < jpa-> haven't there been a few amateur radio satellites already?
2013-09-16T10:28:50 < Thorn> I think they're mostly dead
2013-09-16T10:29:04 < jpa-> according to wikipedia, they are building a new one
2013-09-16T10:29:22 < Thorn> everybody's using classified military sats now

2013-09-16T10:43:12 < dongs> looks like a fucking atmega and a solar cell
2013-09-16T10:43:28 < Thorn> of course it's not, it's a msp430
2013-09-16T10:43:42 < jpa-> it's for a quite low orbit.. and transmitting some crap over radio, who cares if it reboots a few times
2013-09-16T10:43:44 < dongs> oh is that waht it is?
2013-09-16T10:43:59 < jpa-> cc430 to be exact

2013-09-16T10:44:26 < R2COM> there are private aerospace companies who launch that kind of trash on almost monthly basis
2013-09-16T10:44:33 < R2COM> I fail to see anything special about this project
2013-09-16T10:44:53 < R2COM> any company, or even individual can launch his trash up
2013-09-16T10:45:05 < dongs> R2COM: they havent evne launched yet
2013-09-16T10:45:10 < dongs> and they were funded 2 years ago
2013-09-16T10:45:13 < dongs> sounds like they're failing.
2013-09-16T10:45:27 < R2COM> funded by how much?
2013-09-16T10:45:27 < jpa-> dongs: they are cheap solar panels made of the excess pieces that are left when they make rectangular panels
2013-09-16T10:45:36 < dongs> $74,586
2013-09-16T10:45:37 < dongs> pledged of $30,000 goal
2013-09-16T10:45:45 < R2COM> heh thats more than enough to launch
2013-09-16T10:45:52 < dongs> jpa-: you be trollen
2013-09-16T10:45:55 < R2COM> give me half of that and I organize launch
2013-09-16T10:46:06 < R2COM> and let you put your trash onboard
2013-09-16T10:46:12 < jpa-> dongs: http://www.spectrolab.com/DataSheets/PV/PV_NM_TASC_ITJ.pdf
2013-09-16T10:46:29 < dongs> ha
2013-09-16T10:46:53 < dongs> hax
2013-09-16T10:46:55 < Thorn> why are there resistors trying to crawl onto those panels
2013-09-16T10:47:00 < R2COM> anyhow
2013-09-16T10:47:02 < R2COM> so
2013-09-16T10:47:11 < R2COM> what is the mechanism there? 74$k received?
2013-09-16T10:47:16 < R2COM> is he responsible for this money?
2013-09-16T10:47:18 < dongs> Thorn: looks like vcc/gnd "jumpers"?
2013-09-16T10:47:18 < R2COM> or what?
2013-09-16T10:47:21 < dongs> R2COM: yes
2013-09-16T10:47:24 < dongs> asked for 30k
2013-09-16T10:47:26 < dongs> received 72k
2013-09-16T10:47:29 < R2COM> so?
2013-09-16T10:47:34 < R2COM> and if he didnt do the job then what?
2013-09-16T10:47:38 < dongs> that sit
2013-09-16T10:47:43 < dongs> just troll updates section
2013-09-16T10:47:49 < dongs> sorry, our launch vehicle exploded
2013-09-16T10:47:50 < dongs> bai
2013-09-16T10:47:57 < jpa-> yeah, the crawling resistors are marked 000.. i guess easier to solder than wires
2013-09-16T10:48:07 < R2COM> oh screw that shit
2013-09-16T10:48:16 < R2COM> thats why I'd never put a dime on thing like kickstart
2013-09-16T10:48:51 < R2COM> bunch of scammers
2013-09-16T10:49:13 < dongs> http://www.kickstarter.com/projects/microduino/microduino-arduino-in-your-pocket-small-stackable this is fucking terrible
2013-09-16T10:49:27 < dongs> this is basically some chink company that's already been selling their shit in china for most of 2013

2013-09-16T10:49:36 < dongs> just has a nice looking ebay listing on dickstarter
2013-09-16T10:49:53 < R2COM> 28$k for that?
2013-09-16T10:49:56 < R2COM> I dont get it
2013-09-16T10:50:03 < R2COM> maybe I am not a clever man
2013-09-16T10:50:04 < dongs> it still has 33 days to go
2013-09-16T10:50:08 < dongs> it'll likely go over 200k easy
2013-09-16T10:50:46 < dongs> oh. they've been at it since 2012.
2013-09-16T10:50:56 < R2COM> so do some arduino breakout and make project
2013-09-16T10:50:56 < jpa-> it's for starting mass production, according to the page
2013-09-16T10:50:58 < R2COM> make 100$k
2013-09-16T10:51:41 < dongs> basically.
2013-09-16T10:51:46 < dongs> jpa-: they're all chinese.
2013-09-16T10:51:57 < dongs> all the board pics on there look like they were made by seeedstudio
2013-09-16T10:52:07 < dongs> all the parts on there cost basically nothing.
2013-09-16T10:52:19 < jpa-> yeah, massive profit on the price
2013-09-16T10:52:21 < dongs> when they order pcba of that shit in 10k units qty, they're gonna pay almost nothing for it.
2013-09-16T10:52:24 < dongs> right.
2013-09-16T10:52:39 < jpa-> only reason they can sell it is because regular arduino is even more expensive :)
2013-09-16T10:52:52 < R2COM> ok
2013-09-16T10:52:53 < dongs> R2COM: reading http://www.forbes.com/sites/markgibbs/2012/08/20/the-truth-about-kickstarter-and-zioneyez/
2013-09-16T10:52:56 < R2COM> but what is big deal about it?
2013-09-16T10:53:00 < R2COM> microduiuno?
2013-09-16T10:53:00 < dongs> no deal
2013-09-16T10:53:04 < dongs> its failmega328
2013-09-16T10:53:05 < R2COM> so its small so fucking what
2013-09-16T10:53:06 < dongs> on a square pcb.
2013-09-16T10:53:09 < dongs> thats all.
2013-09-16T10:53:12 < dongs> and its "arduino compatible"
2013-09-16T10:53:16 < R2COM> lol
2013-09-16T10:53:23 < dongs> not joking.
2013-09-16T10:53:24 < jpa-> because arduino-dudes can't fit their regular arduinos in their ass
2013-09-16T10:53:31 < jpa-> so they need microduino for their dildos
2013-09-16T10:54:14 < dongs> basically, keywords for any dickstarter instant success
2013-09-16T10:54:18 < dongs> 1) arduino-comaptible
2013-09-16T10:54:20 < dongs> 2) raspberri pi
2013-09-16T10:54:22 < dongs> 3) iphone
2013-09-16T10:54:37 < dongs> so anything that uses any (preferably all) of those = instant millions.
2013-09-16T10:54:46 < R2COM> why dont you do it then/
2013-09-16T10:54:48 < R2COM> ?
2013-09-16T10:54:55 < R2COM> I mean create some project which uses all 3?
2013-09-16T10:55:00 < dongs> i duno, i can't think of anything so dumb taht only iphone users would want it
2013-09-16T10:55:07 < R2COM> heh
2013-09-16T10:55:08 < Thorn> and promise to launch it in space
2013-09-16T10:55:11 < dongs> a pal suggested
2013-09-16T10:55:17 < dongs> i just put up shit i currently sell
2013-09-16T10:55:21 < Thorn> there're phonesat projects out there
2013-09-16T10:55:23 < dongs> at higher price on dickstarter.
2013-09-16T10:55:35 < dongs> no reason, just copypaste same shit exactly as im currently making.
2013-09-16T10:55:42 < dongs> worst case scenario: I sell stuff.
2013-09-16T10:56:21 < dongs> http://www.able-hd.com/order.html
2013-09-16T10:56:36 < dongs> http://i.imgur.com/4T9IK66.jpg got this from china shipped for $27
2013-09-16T10:56:44 < dongs> that kickstarter idiot is sellin same trash for $51
2013-09-16T10:56:46 < dongs> WITH shipping.
2013-09-16T10:57:12 < R2COM> so whats about that board

2013-09-16T10:57:38 < MrMobius> do many people get sued for making kickstarters from already patented things?

2013-09-16T10:58:23 < Thorn> why that huge resistor (R107)
2013-09-16T10:59:08 < Thorn> is it Chinese for "switch mode converter"?
2013-09-16T11:00:07 < R2COM> if product gets developed do backers get something back?
2013-09-16T11:01:06 < Thorn> the sidebar on the right says what you get depending on the amount you throw at them
2013-09-16T11:02:56 < R2COM> meh
2013-09-16T11:03:31 < R2COM> so in other words, or in general its something like: give me money, I will try, if I fail, I am sorry but you wont get anything then.
2013-09-16T11:03:32 < R2COM> right?
2013-09-16T11:04:01 < dongs> yes
2013-09-16T11:04:41 < dongs> its a perfectly legal scam.
2013-09-16T11:05:22 < R2COM> something like government funded projects in educational environment?
2013-09-16T11:05:36 < R2COM> (in US at least...)
2013-09-16T11:06:08 < R2COM> when theres proposa, followed by funding, followed by fail, and followed by nice report like "we failed but we learned a lot, thank you"

2013-09-16T11:21:51 < dongs> of course it is
2013-09-16T11:22:14 < jon1012> at least they are not making a kickstarter for the usb condom (http://hothardware.com/News/Wrap-That-Rascal-With-A-USB-Condom/ )
2013-09-16T11:22:47 < dongs> The trouble is that big ultra-bright white SMT LED's are really expensive compared to ultra-bright red SMT LED's. That is unless you order a lot of them at once. We have managed to find them at a good price but we would need to buy 100,000 LED's at once.
2013-09-16T11:22:52 < dongs> the fuck
2013-09-16T11:23:03 < dongs> i paid something like 40bucks for a reel of 4k 0805 leds

2013-09-16T11:24:18 < capacitor> these guys are really switched on!

2013-09-16T11:25:13 < dongs> which is pretty unlikely
2013-09-16T11:25:20 < dongs> so 25 reels * 40 bucks = $1k?

2013-09-16T11:38:17 < jon1012> mmh, I backed two projects that I think differ from what you said :

2013-09-16T11:39:10 < R2COM> project #1, no big deal
2013-09-16T11:39:23 < R2COM> there are if I am correct *freely* available algorithms for that shit in MATLAB
2013-09-16T11:39:24 < jon1012> the pixy is mainly engineering works toward making computer vision simple, sure you can do it yourself, but when you don't have time to, seems a nice way to go
2013-09-16T11:39:30 < R2COM> anyone can implement it on *any* platform
2013-09-16T11:39:39 < R2COM> so what big deal in it?
2013-09-16T11:39:41 < R2COM> nothing
2013-09-16T11:39:46 < R2COM> nothing big/special
2013-09-16T11:39:49 < R2COM> nothing new
2013-09-16T11:40:00 < jon1012> it's not a big deal, just a nice sensor to have on hand
2013-09-16T11:40:00 < jpa-> it's easy to use for people who are not able to do it themselves

2013-09-16T12:58:13 < Luggi09> dongs: I just changed baro stuff so it uses groundTemperature
2013-09-16T12:59:04 < Luggi09> the baro shows 30° C whereas my room is 21.6°C that isn't reliable for sure
2013-09-16T13:01:00 < dongs> so is that good or bad
2013-09-16T13:01:28 < Luggi09> bad, because you want the air temperature at the start
2013-09-16T13:01:53 < Luggi09> it could also be because my board has been running for 10mins and it heated up a bit
2013-09-16T13:08:08 < jon1012> mmhh

2013-09-16T13:14:17 < jpa-> hmm.. now that i google it again, looks like it is because of WFI
2013-09-16T13:14:27 < jpa-> strange that texane stlink is just fine with it
2013-09-16T13:16:15 < PaulFertser> Probably texane enables some "debug while asleep" it on its own.

2013-09-16T13:19:02 < jpa-> yeah, could be
2013-09-16T13:19:12 < jpa-> might be sensible for openocd to do it also
2013-09-16T13:19:51 < jon1012> btw, someone knows what is this chrom art stuff and how I can use it (with gcc) ?
2013-09-16T13:21:30 < jpa-> it's pretty similar to DMA, but supports things like "blend values from source A and source B together"
2013-09-16T13:21:51 < jpa-> i expect you should be able to use it much like DMA, i.e. write some values to registers and tell it to start doing its thing
2013-09-16T13:27:40 < jon1012> ok
2013-09-16T13:27:50 < jon1012> I have to try that
2013-09-16T13:28:58 < jon1012> btw, I'm currently doing bitbang at high speed on 6*6 data channels with just one clock, would there be any nice way to do that with dma ?
2013-09-16T13:29:34 < trepidaciousMBR> Do you think ST might ever release the STLink V2 firmware source? Would be great to make a serial + SWD dongle
2013-09-16T13:29:34 < jon1012> (last time I checkec I though there was none, but as I'm a beginner with dma I may be wrong)
2013-09-16T13:29:49 < karlp> trepidaciousMBR: you mean, just like the BMP?
2013-09-16T13:29:54 < zyp> trepidaciousMBR, there are already more decent options for that
2013-09-16T13:29:57 < zyp> like BMP
2013-09-16T13:30:22 < karlp> difference would be being able to select "stlink" in some of the $tools
2013-09-16T13:30:29 < jpa-> jon1012: sure, bitbang using DMA has always been possible
2013-09-16T13:31:28 < jpa-> jon1012: see for example this file that does bitbang to GPIOB->BSRR using DMA: https://github.com/PetteriAimonen/QuadPawn/blob/master/Runtime/fpga.c
2013-09-16T13:31:53 < jon1012> thanks
2013-09-16T13:32:35 < jpa-> jon1012: it gets a bit more involved if you need to synchronize writes to multiple ports
2013-09-16T13:33:12 < jon1012> ok
2013-09-16T13:33:19 < jon1012> yeah that's what I need :(
2013-09-16T13:33:26 < jpa-> it's not impossible
2013-09-16T13:33:45 < jpa-> just use multiple DMA channels, either triggered from the same timer or from multiple synchronized timers
2013-09-16T13:33:53 < PaulFertser> stlink supports SWO out of the box, with BMP it's still not really there.
2013-09-16T13:33:53 < jpa-> the writes will not happen on the same clock cycle
2013-09-16T13:34:05 < jon1012> ok
2013-09-16T13:34:07 < jpa-> but they don't happen on the same cycle either when you do it by software so..
2013-09-16T13:34:32 < jpa-> using dma priorities, you can control which port gets toggled first
2013-09-16T13:36:07 < jon1012> you used a lot of notions I don't fully understand yet, but I'll try to learn, thanks for the explanation
2013-09-16T13:38:23 < jon1012> (like dma priorities, never touched that yet)
2013-09-16T13:39:20 < Posterdati> hi
2013-09-16T13:39:42 < Posterdati> zyp: please, have you got any example on how transfer > 64 bytes data via usb hid? tx
2013-09-16T13:40:03 < zyp> that's not possible
2013-09-16T13:42:15 < Posterdati> yes
2013-09-16T13:42:17 < Posterdati> I mean
2013-09-16T13:42:30 < Posterdati> how can you transfer > 64 bytes using usb?
2013-09-16T13:42:44 < Posterdati> you have to call several time usb write
2013-09-16T13:43:04 < zyp> depends on what transport type you are using
2013-09-16T13:43:18 < Posterdati> ?
2013-09-16T13:43:19 < Posterdati> hid
2013-09-16T13:43:43 < zyp> HID is based on interrupt transport, and interrupt transport only does single packet transfers, and on FS the interrupt packet size can't be larger than 64 bytes
2013-09-16T13:43:55 < zyp> so it's simply impossible to have larger HID transfers than 64 bytes
2013-09-16T13:44:01 < Posterdati> ok
2013-09-16T13:44:16 < Posterdati> so I called several times usb.write
2013-09-16T13:44:52 < Posterdati> advancing data pointer of 64 bytes at the time
2013-09-16T13:44:55 < zyp> I believe I've told you multiple times that HID is not the right choice for what you want to do, so it's your own fault :p
2013-09-16T13:45:17 < Posterdati> and what I suppose to use?
2013-09-16T13:46:46 < Posterdati> bulk transfer?
2013-09-16T13:46:57 < karlp> for transferring.... bulk stuff... yes. perhaps
2013-09-16T13:47:13 < zyp> yes, bulk would be the appropriate transfer
2013-09-16T13:47:27 < zyp> transport*

2013-09-17T01:17:39 < Posterdati> don't know
2013-09-17T01:17:48 < Posterdati> I saw it is variable
2013-09-17T01:17:55 < zyp> see, that's my point :)
2013-09-17T01:17:59 < Posterdati> yes
2013-09-17T01:18:17 < zyp> don't dick with timeouts until you actually have a time reference in place
2013-09-17T01:18:24 < zyp> if you do have a time reference in place, use it
2013-09-17T01:18:35 < Posterdati> but how prevent that function to block if using only while?
2013-09-17T01:19:20 < Posterdati> anyway
2013-09-17T01:19:28 < Posterdati> I changed to a circular buffer
2013-09-17T01:19:39 < Posterdati> and pushed out data every 64 bytes
2013-09-17T01:21:52 < Posterdati> or it is convenient not to write 64 bytes at the time in the IN endpoint

2013-09-17T05:33:41 < R2COM> what I said seems to be limit of ADI.
2013-09-17T05:36:40 < emeb_mac> SiLabs stuff seems to poop out at about 250fs
2013-09-17T05:36:51 < R2COM> yeah thats what their parts are around
2013-09-17T05:37:44 < R2COM> and most manufacturers characterize 10kHz:20MHz range... which for most adc clocking applications is useless to me actually
2013-09-17T05:38:00 < emeb_mac> ya
2013-09-17T05:38:11 < emeb_mac> TI's idea of low jitter is < 500fs

2013-09-17T05:38:32 < emeb_mac> yup
2013-09-17T05:39:05 < R2COM> sometimes I know ADI uses some sort of custom crystals with very low jitter to characterize adc
2013-09-17T05:39:09 < R2COM> but they are expencive
2013-09-17T05:39:44 < emeb_mac> no doubt
2013-09-17T05:40:00 < emeb_mac> what you doing that needs such tight specs?
2013-09-17T05:40:24 < R2COM> just thinking of squeezing max snr from adc
2013-09-17T05:41:08 < emeb_mac> must have some high slew rates on the input signal to warrant that kind of clock jitter.
2013-09-17T05:42:29 < R2COM> or provide it with higher amplitude or frequency (given that frequency divided later back to proper one)
2013-09-17T05:42:33 < R2COM> but then it complicates things
2013-09-17T05:42:57 < R2COM> I could use adc's internal clock divider, but theres not much said about how much that internal divider would add jitter
2013-09-17T05:43:25 < R2COM> I see some parts now from adi, with 100fs parameter anyhow..
2013-09-17T05:43:33 < emeb_mac> aha
2013-09-17T05:43:48 < R2COM> was just wondering if some company managed to make a better , cleaner part, for same money, or at least for something not very expencive
2013-09-17T05:46:08 < GargantuaSauce_> 100 femtoseconds?!
2013-09-17T05:46:26 < emeb_mac> tight, no?
2013-09-17T05:47:20 < GargantuaSauce_> isnt that completely irrelevant if two paths in the clock tree differ in length by....30 microns?!
2013-09-17T05:47:37 < R2COM> yes.
2013-09-17T05:48:30 < R2COM> I mean no.
2013-09-17T05:50:53 < R2COM> what you described has more to do with clock skew.

2013-09-17T06:29:21 < gxti> i can't really come up with a GOOD reason for a bootloader that can do relocations, but it would be neat
2013-09-17T06:30:02 < gxti> a more practical solution is to just make the bootloader at the end of flash except for the first page, then always compile stuff to start at the second page.
2013-09-17T06:31:13 < GargantuaSauce_> support for loading code to sram for a quicker development process maybe?
2013-09-17T06:32:02 < gxti> well for development you can just recompile
2013-09-17T06:32:16 < gxti> plus if you load at 0 instead of 08000000 then it works both ways

2013-09-17T07:09:25 < R0b0t1> you'd only need to relocate a few instructions at the start and could fit your own code in wherever convenient

2013-09-17T07:54:07 < dongs> haha
2013-09-17T07:57:13 < R2COM> start reviewing some mor kickstarter projects, just for the fun of it
2013-09-17T07:57:38 < R2COM> find some million dollar funded arduino compatible device
2013-09-17T07:58:47 < GargantuaSauce_> make a kickstarter to buy into a bunch of kickstarters and produce naza-unboxing style videos
2013-09-17T07:59:33 < GargantuaSauce_> you can send people the fragments as perks
2013-09-17T08:00:26 < dongs> not a terrible idea
2013-09-17T08:00:34 < dongs> i wonder how did that indiegogo to buy out dickstarter went
2013-09-17T08:01:20 < dongs> http://www.kickstarter.com/projects/540550394/parashoot-20-multi-use-wearable-smart-hd-camera
2013-09-17T08:01:23 < dongs> hmm
2013-09-17T08:01:26 < dongs> suspended?
2013-09-17T08:02:15 < R2COM> w117$k wtf
2013-09-17T08:02:21 < R2COM> for hanging camera ?
2013-09-17T08:02:24 < R2COM> I dont get it
2013-09-17T08:02:42 < R2COM> or didi he develop some new better type of image sensor chip
2013-09-17T08:02:58 < dongs> i think someone sniffed out that it was just repackaged chinese shit
2013-09-17T08:03:42 < dongs> If you want this camera, you can get it on ebay. Just search for "Unieye". You can get it for $104 including a waterproof case, bike clip and belt clip. Looking at the camera specs, it matches exactly with the one offered here on the Kickstarter.
2013-09-17T08:03:46 < R2COM> board pcb design (propriatary) wow... how scary, as its some sort of pcb from top end military image sensor board. lol

2013-09-17T08:05:49 < R2COM> is camera on kickstarter website compatible to those 3 things you mentioned?
2013-09-17T08:06:01 < R2COM> if no, then how did he get 117$k
2013-09-17T08:06:01 < R2COM> ?

2013-09-17T08:07:58 < englishman> nice pcb antenna
2013-09-17T08:08:03 < dongs> when I pasted it last time it was some shitty NuVoTon CPU
2013-09-17T08:08:23 < R2COM> maybe thats why their project got suspended?
2013-09-17T08:08:28 < dongs> well yes
2013-09-17T08:08:35 < dongs> they're basiclaly reseling those $95 ebay cams

2013-09-17T08:08:46 < dongs> for... $269
2013-09-17T08:08:48 < R2COM> how stupid they had to be to do that
2013-09-17T08:09:03 < dongs> R2COM: apparnetly stupid enough to get $120

2013-09-17T08:09:36 < dongs> that shouldn't be hard since you aren't employed right?
2013-09-17T08:09:38 < dongs> so anything > 0
2013-09-17T08:09:51 < englishman> i think i .... no.... yeah
2013-09-17T08:10:06 < englishman> or, -1000 or so
2013-09-17T08:10:23 < R2COM> so. there has to be some sort of a shitlist for those people
2013-09-17T08:10:28 < R2COM> in all possible projects
2013-09-17T08:10:31 < R2COM> and job positions

2013-09-17T08:12:08 < R2COM> maybe its not, who knows
2013-09-17T08:12:15 < dongs> that shit was just bought straight from china
2013-09-17T08:12:21 < dongs> but good timing and noone noticed
2013-09-17T08:12:44 < R2COM> in reality those might be completely different people
2013-09-17T08:12:58 < englishman> maybe you can report the square arduino and get it suspended too

2013-09-17T08:16:12 < R2COM> heres a question
2013-09-17T08:16:15 < dongs> haha
2013-09-17T08:16:41 < R2COM> for example, goal was 100$k, lets say you won it, then what next? you have to use all that money to build devices, and them give them all out or what?
2013-09-17T08:16:53 < dongs> no
2013-09-17T08:16:56 < dongs> lol
2013-09-17T08:17:02 < englishman> 8% to kickstarter
2013-09-17T08:17:03 < dongs> you ship exactly what faggots asked for
2013-09-17T08:17:05 < dongs> yeah
2013-09-17T08:17:07 < dongs> minus fees / etc
2013-09-17T08:17:10 < dongs> then you keep the rest
2013-09-17T08:17:16 < englishman> 92% private contract between you and company
2013-09-17T08:17:26 < dongs> so if you say it'll cost you 20k for components but you buy clones in china for 2k instead,  youcan pocket the rest.
2013-09-17T08:17:31 < englishman> pay self, company closes = you suck
2013-09-17T08:18:06 < dongs> check out that fcc link
2013-09-17T08:18:38 < englishman> diff pcb?
2013-09-17T08:19:07 < englishman> yeah the fcc link has ambarella
2013-09-17T08:19:22 < dongs> right, that cam isnt so bad for $95 actually
2013-09-17T08:19:27 < dongs> but not for $269 lolol
2013-09-17T08:19:42 < R2COM> but if i spend say 20$k on components (or 2k doenst matter for now), and I promised that once I get all uints built I will sell each for say... 100$ whereas each module costed me 20$ to build, then its all I must do to fullfill my objectives for pledgers? (and plus give out 8% to kickstarter)
2013-09-17T08:19:43 < englishman> compare https://s3.amazonaws.com/ksr/assets/000/907/835/5b70594a63fffb6a7f2580a822cc46dc_large.jpg?1378839072
2013-09-17T08:19:56 < dongs> R2COM: yes
2013-09-17T08:20:00 < englishman> what do you think?
2013-09-17T08:20:03 < dongs> of course youre not obligated to make not a single unit more
2013-09-17T08:20:05 < englishman> they are not shareholders
2013-09-17T08:20:13 < dongs> englishman: that amazon link is some SD trash
2013-09-17T08:20:21 < dongs> they just pulled that out of thier ass.
2013-09-17T08:20:26 < englishman> oh i thought it was from the kickstarter
2013-09-17T08:20:30 < dongs> it is
2013-09-17T08:20:32 < dongs> but what i mean is
2013-09-17T08:20:36 < dongs> its not insides of the cam.
2013-09-17T08:20:39 < englishman> hahah
2013-09-17T08:20:42 < dongs> just some random trollcam pcb
2013-09-17T08:20:50 < dongs> probably something $5 from delayextreme
2013-09-17T08:21:38 < R2COM> but see it wasnt arduino or other thing compatible
2013-09-17T08:21:42 < R2COM> and he got 117$k
2013-09-17T08:21:51 < R2COM> you said only those 3 key things lead to success there
2013-09-17T08:22:02 < dongs> it got cancelled
2013-09-17T08:22:03 < dongs> for scam
2013-09-17T08:22:10 < dongs> thats not  success.
2013-09-17T08:22:12 < R2COM> thats different thing
2013-09-17T08:22:23 < R2COM> but point is he made it to 117k before got cancelleed\
2013-09-17T08:22:33 < R2COM> means that if it were not a scam, it would not have been cancelled
2013-09-17T08:22:33 < englishman> it has a panda
2013-09-17T08:22:34 < dongs> yes
2013-09-17T08:22:35 < R2COM> or am I wrong
2013-09-17T08:22:39 < dongs> correct
2013-09-17T08:22:47 < englishman> panda = female dollars
2013-09-17T08:23:02 < R2COM> well... turns out that not only arduino/rb.pi/iphone5 projects have chance on kickstarter then
2013-09-17T08:23:31 < dongs> well, those that arent scam, would require actual work
2013-09-17T08:23:46 < dongs> tarduino/rapepi/iphone5 you are guaranteed success without work
2013-09-17T08:23:53 < R2COM> okay
2013-09-17T08:24:19 < R2COM> I'm just wondering now how come those 3 things get sponsored so hard. and why.
2013-09-17T08:24:28 < R2COM> does it mean that majhority of people just like lame trash...
2013-09-17T08:24:39 < dongs> yes
2013-09-17T08:24:44 < dongs> why the fuck do you think arduino is popular
2013-09-17T08:24:49 < dongs> its not amazing or anything by any means
2013-09-17T08:24:50 < dongs> its just trash
2013-09-17T08:26:58 < R2COM> maybe those who sell those arduinos know it too, and laugh at majority of people
2013-09-17T08:27:31 < R2COM> anyhow
2013-09-17T08:27:32 < R2COM> yeah
2013-09-17T08:27:36 < R2COM> serious shit requires work
2013-09-17T08:27:45 < R2COM> time consuming and super tedious work
2013-09-17T08:27:55 < R2COM> and high failure rate...
2013-09-17T08:28:10 < R2COM> but then...that project looks kinda weird...and less people would want to pledge on it..I assume.
2013-09-17T08:28:11 < PaulFertser> There's a large niche of people who want to create something based on simple building blocks. I know a lawyer who implemented means for remote house equipment control just by combining a soho wifi router with OpenWrt with a GSM usb dongle with an arduino board with a "shield" having several relays. He created a system without any deep understanding of programming or electronics. And yet the system is custom and does what he needs.
2013-09-17T08:29:05 < dongs> around here, we call that kinda shit "ghetto"
2013-09-17T08:29:34 < R2COM> big fun would be if his house sets on fire one day due to some improperly connected shit
2013-09-17T08:29:35 < PaulFertser> You do not expect kids to do welding for their constructions, and instead you give them some simple blocks to assemble what they want.
2013-09-17T08:30:07 < PaulFertser> Arduino and shit like that allows more people to do interesting things.
2013-09-17T08:30:23 < R2COM> i would not call them interesting
2013-09-17T08:30:27 < PaulFertser> Interesting for them.
2013-09-17T08:31:05 < R2COM> you can go ahead buy lego, and use its parts to make a replacement in your car or something. also interesting
2013-09-17T08:31:14 < R2COM> or you can: learn how to do it properly
2013-09-17T08:31:17 < R2COM> or: let someone do it
2013-09-17T08:31:19 < emeb_mac> there - I fixed it!
2013-09-17T08:31:47 < PaulFertser> I've seen enough shit repair work by "professional mechanics". They usually do not have a clue either.
2013-09-17T08:31:58 < emeb_mac> http://www.youtube.com/watch?v=W8fdXNN0irI
2013-09-17T08:32:13 < PaulFertser> Also, sometimes you need at least some solution to get to the place where you can fix it properly.
2013-09-17T08:33:11 < R2COM> anyhow
2013-09-17T08:33:19 < R2COM> that is why..hobbyists of today are *lame* :)
2013-09-17T08:33:27 < PaulFertser> IMHO it's much better that there're people who at least try to think and create something instead of consuming all that shit designed and produced by professionals.
2013-09-17T08:34:03 < R2COM> if you want to think...go spend some little time learning on how do *design* shit
2013-09-17T08:34:12 < R2COM> not do things by "copy paste" method
2013-09-17T08:34:18 < R2COM> and then get excited that shit works
2013-09-17T08:34:25 < R2COM> since that is not a *real* thinking
2013-09-17T08:34:36 < R2COM> thinking - solving problems
2013-09-17T08:35:07 < R2COM> but if problem is too abstract, with those high level toys which doesnt take much to think
2013-09-17T08:35:10 < R2COM> then theres no benefit
2013-09-17T08:35:13 < dongs> ha ha
2013-09-17T08:35:15 < PaulFertser> I know. But it's still better then not trying to do anything at all.
2013-09-17T08:35:17 < R2COM> he didnt actually learn anything
2013-09-17T08:35:19 < dongs> asking tarduino dudes to "design" without "copypaste"
2013-09-17T08:35:22 < R2COM> just "cheated"
2013-09-17T08:35:36 < dongs> thats like asking water  to be dry or something.
2013-09-17T08:35:47 < dongs> 99.999% of tarduino shit is just copypasted aids
2013-09-17T08:35:49 < R2COM> again you stuck at this "its still better" thing...
2013-09-17T08:35:52 < PaulFertser> Most proprietary code I saw was "designed" by copypasting and cheating.
2013-09-17T08:35:54 < dongs> without any understanding of programming language or concepts or whatever
2013-09-17T08:36:00 < dongs> fuck, the IDE basically encourages writing shit code
2013-09-17T08:36:05 < dongs> because it has no syntax highlight or indnetation or whatever
2013-09-17T08:36:11 < PaulFertser> lol, really?
2013-09-17T08:36:26 < dongs> yea arduino IDE editor is fucking HORRIBLE
2013-09-17T08:36:38 < R2COM> guess what
2013-09-17T08:36:45 < R2COM> if someone wants to learn bsic circuits
2013-09-17T08:36:54 < R2COM> its one book, and its like 2-3 months time to read and go through it
2013-09-17T08:36:59 < MrMobius> "well if i just want to blink a few LEDs..."
2013-09-17T08:37:00 < R2COM> similar amount for some programming language
2013-09-17T08:37:10 < R2COM> and then do things in  a *right* way
2013-09-17T08:37:11 < MrMobius> i dont know who these people are who go around blinking leds all day
2013-09-17T08:37:20 < R2COM> and that means person *learned* something
2013-09-17T08:37:47 < R2COM> not buy some trash, then browse tard forums, then look at online "connect red to black" type of manuals, and then get excited as hell that your shit worked
2013-09-17T08:37:50 < PaulFertser> btw, talking about programming languages. There's apparently a working Haskell compiler and library for stm32s, have anyone tried it?
2013-09-17T08:38:33 < dongs> i thought you were talking about programming languages, since when does haskell classify as one?
2013-09-17T08:38:52 < PaulFertser> Since it was introduced, of course.
2013-09-17T08:39:55 < dongs> sounds like another write-only language like python
2013-09-17T08:40:23 < GargantuaSauce_> i've been meaning to try doing some functional stuff
2013-09-17T08:40:31 < GargantuaSauce_> i don't think I'll do it embedded though <_<
2013-09-17T08:40:41 < PaulFertser> Regarding those arduino cheaters, well, I try to avoid judging people, I personally prefer to learn properly but I also see that some programmers or electronic engineers or other folks prefer to do some shitty work. But I also can see how that shitty work can end up beneficial for the society or some particular business. So I think it's up to them to do what they want if they're not evil.
2013-09-17T08:40:42 < R2COM> I'm now reading C#
2013-09-17T08:41:00 < dongs> write once read never
2013-09-17T08:41:17 < R2COM> I wrote already couple apps
2013-09-17T08:41:26 < R2COM> now need to make GUI version of them
2013-09-17T08:41:50 < PaulFertser> dongs: I've read some Xmonad-contrib source code and modified it, can't say it's harder than usual. Haskell is supposed to be expressive and clean, and it seems to be the case mostly.
2013-09-17T08:42:39 < PaulFertser> btw, even microsoft introduced a functional programming language F# (it's similar to OCaml) as a standard part of their studio.
2013-09-17T08:42:45 < R2COM> so its something like, defining shit with formula expressiuons?
2013-09-17T08:42:48 < GargantuaSauce_> F# is a monstrosity
2013-09-17T08:42:51 < dongs> R2COM: wtf why would you use C# for GUI. use PyGTKOcamlQtXML instead, then  you can ship a 100 meg runtime of opensores libs with your apps but it'll surely work on lunix/mac/windows (notice how iwndows at hte end o the list)
2013-09-17T08:43:04 < R2COM> dongs: wat
2013-09-17T08:43:24 < R2COM> why do I have to ship opensores libs?
2013-09-17T08:43:29 < PaulFertser> dongs: you need to ship .NET runtime for C# anyway.
2013-09-17T08:43:35 < R2COM> I dont even want to deal with all that trash are you kidding
2013-09-17T08:43:42 < dongs> PaulFertser: "ship"? hello its fucking 2013.
2013-09-17T08:43:52 < dongs> PaulFertser: i'd be surprised if there's more than 1% of MODERN PCS without .NET runtime already on them
2013-09-17T08:43:59 < R2COM> everyone got .NET runtime installed
2013-09-17T08:44:01 < dongs> shit, vista/7 fucking included some .net runtim already
2013-09-17T08:44:03 < R2COM> is this a joke PaulFertser?
2013-09-17T08:44:26 < PaulFertser> dongs: and take a look on the history of GUI development offerings from MS over the time: plain WinAPI, MFC, ATL, WinForms, new WinForms, XAML etc... I can't say they're consistent.
2013-09-17T08:44:49 < dongs> only the last 3 require some "runtime"
2013-09-17T08:45:02 < dongs> and xaml was dead before it was even alive
2013-09-17T08:45:11 < PaulFertser> R2COM: I see some people around still using windows xp and they do not have .net runtime installed, or it's some older version that doesn't support the new gui fad from ms.
2013-09-17T08:45:39 < R2COM> PaulFertser: those are probably some ghetto people without internet
2013-09-17T08:45:42 < PaulFertser> dongs: vscrt shared library is runtime too
2013-09-17T08:45:43 < R2COM> and dont have updates turned on
2013-09-17T08:45:51 < dongs> PaulFertser: and?
2013-09-17T08:45:52 < PaulFertser> R2COM: probably so
2013-09-17T08:45:59 < dongs> PaulFertser: if  you build  your app correctly, its not needed
2013-09-17T08:46:01 < PaulFertser> dongs: MFC required that runtime iirc
2013-09-17T08:46:12 < dongs> there's like20 versions of mfc shipped with every windows install
2013-09-17T08:46:13 < PaulFertser> If you think static linking is good, well, ok.
2013-09-17T08:46:15 < dongs> no, its note required.
2013-09-17T08:46:35 < R2COM> I have don C++ GUI Apps long long time ago for some people/places, that shit still works I know it.. and they changed systems already
2013-09-17T08:46:49 < R2COM> and the development environment and doc. support is nice from MSDN
2013-09-17T08:46:55 < PaulFertser> With MFC?
2013-09-17T08:46:58 < R2COM> clean nice conditions to develop anything
2013-09-17T08:47:07 < R2COM> I dont remember what it was cant say now.
2013-09-17T08:47:22 < R2COM> I think yes
2013-09-17T08:47:46 < PaulFertser> I know microsoft devs themselves were so unhappy with MFC that they designed ATL/WTL on their spare time.
2013-09-17T08:48:26 < R2COM> not sure... but I know one thing: If I decide to do that GUI shit on linux, I will be more unhappy.

2013-09-17T08:50:28 < R2COM> C# is just best language I guess to do anything GUI related on windows platform
2013-09-17T08:50:53 < R2COM> plus..it can also call unmanaged code or something like that, or another .dll's if needed, written in another language
2013-09-17T08:51:19 < PaulFertser> Hobby amateurs designed https://en.wikipedia.org/wiki/AO-7 which is still operational in space after 39 years.
2013-09-17T08:51:41 < PaulFertser> GargantuaSauce_: talking about wx, well, it's sort of MFC clone :)

2013-09-17T09:27:02 < R2COM> its not big deal shit
2013-09-17T09:27:07 < R2COM> people do this shit everytime
2013-09-17T09:27:10 < jpa-> because so many people wanted to buy it at the price?
2013-09-17T09:27:28 < R2COM> arent there arleady even cheaper boards madeinchina?
2013-09-17T09:27:54 < jpa-> sure, if you know and bother to shop around
2013-09-17T09:29:01 < R2COM> one more question
2013-09-17T09:29:23 < R2COM> if project on kickstarter is uncussessfull, and before deadline some amount was pledged, does that amount burn?
2013-09-17T09:29:26 < R2COM> or you still get it?
2013-09-17T09:29:39 < jpa-> on kickstarter, the backers get their money back
2013-09-17T09:29:54 < R2COM> yeah makes sense
2013-09-17T09:30:10 < jpa-> on indiegogo, if you have "flexible funding", the project still gets the money but they also need to provide the same results.. so they have to choose if the smaller amount is enough
2013-09-17T09:30:45 < R2COM> indiegogo is just copy of kickstarter?
2013-09-17T09:30:55 < jpa-> mostly
2013-09-17T09:31:09 < jpa-> i think kickstarter is US-only for projects
2013-09-17T09:31:41 < R2COM> so kickstarter only serves those who are in US?
2013-09-17T09:32:21 < jpa-> the backers can be from anywhere i think but the project needs some kind of address in US, i think.. i haven't checked the rules lately

2013-09-17T10:06:46 < R2COM> sooo... toying around trying to make high fidelity thing out of cheap stuff is tedious.

2013-09-17T12:52:38 < zyp> oh, and I would like one board without the connectors assembled
2013-09-17T12:53:09 < zyp> that way I can just solder some sort of female headers to the connector pads, then shove it into the other boards to run a test
2013-09-17T12:53:54 < dongs> yeah sure
2013-09-17T12:54:01 < dongs> there will probably be a couple extras anyway
2013-09-17T12:54:17 < dongs> as well as plenty of blank ones.
2013-09-17T12:54:24 < dongs> as pcb will usually give 1-2 extra panels

2013-09-17T13:41:15 < Laurenceb_> dma sucks less than interrupts
2013-09-17T13:41:24 < Laurenceb_> if you have the dma channels spare
2013-09-17T13:41:29 < Laurenceb_> but F1 dma is fail
2013-09-17T13:41:29 < dongs> o yeah, they're using DMA
2013-09-17T13:41:30 < dongs> i see.
2013-09-17T13:41:47 < jpa-> nice that they also have tests for that
2013-09-17T13:42:13 < jpa-> it's annoying how few embedded systems have proper test cases

2013-09-17T19:21:52 < Robint91> hi all
2013-09-17T19:21:58 < Robint91> my fatfs works
2013-09-17T19:22:06 <+Steffanx> :)
2013-09-17T19:22:45 < Robint91> I had somewhere a typo in my interrupt handler
2013-09-17T19:23:03 < talsit> Laurenceb_ which camera is that?
2013-09-17T19:23:12 < Robint91> but it is stupid that you can't use the sdcard and the i2s dac at the same time on the discovery
2013-09-17T19:23:34 < emeb> Robint91: how did you do fatfs?
2013-09-17T19:23:41 < Robint91> emeb, SDIO
2013-09-17T19:23:56 < emeb> kewl
2013-09-17T19:24:09 < emeb> what did you do for actually handling the filesystem?
2013-09-17T19:24:16 < Robint91> I haven't benchmakred it correctly
2013-09-17T19:24:21 < Robint91> but it is quite fast
2013-09-17T19:24:57 < Robint91> emeb, compile the right files, fatfs is reasonable to port
2013-09-17T19:25:04 < Laurenceb_> talsit: the one dongs linked
2013-09-17T19:25:07 < Robint91> but the SDIO drivers are horrible

2013-09-17T19:25:18 < emeb> did you write the fat layer yourself or did you grab existing code like ff9a?
2013-09-17T19:25:30 < talsit> dongs links like 15 things per minute
2013-09-17T19:25:42 < Robint91> emeb, http://elm-chan.org/fsw/ff/00index_e.html fatfs
2013-09-17T19:25:49 <+Steffanx> No, now are you wrong talsit. That is Laurenceb_
2013-09-17T19:26:00 < emeb> Robint91: yeah - that's the one I used too.
2013-09-17T19:26:10 < Robint91> emeb, that thing is defacto the standard
2013-09-17T19:26:18 < emeb> aye.
2013-09-17T19:26:22 < Robint91> to implement fat on embedded systems
2013-09-17T19:27:31 < emeb> works fine w/ spi on my f373 & f303 boards.

2013-09-18T12:50:14 < Thorn> lol. Vdd_CAN limits in the LPC11C2x datasheet are 2.8...5.5V. revision 3.1 adds a note that says "VDD_CAN must be equal to the VDD of the microcontroller" (which is 1.8...3.6V)
2013-09-18T12:52:24 < Thorn> at least one (Olimex) board has 5V on VDD_CAN
2013-09-18T12:55:09  * PaulFertser wonders if it leaks those 5V to the VDD as the result :)
2013-09-18T12:55:36 < jpa-> i wonder if it is supposed to be "greater or equal to" or something
2013-09-18T12:57:41 < PaulFertser> Sounds likely indeed.
2013-09-18T12:59:30 < Thorn> it also means you can't power the core from <2.5V
2013-09-18T12:59:40 < Thorn> or even <2.8V

2013-09-18T17:29:30 <+Steffanx> You should add a windows server to it, install a vnc client on that and a vnc server on the linux pc
2013-09-18T17:29:42 < dongs> vnc fucking sucks

2013-09-18T17:30:20 < gxti> i mean better than not having it, but shitty compared to rdp
2013-09-18T17:30:45 < gxti> irrelevant though because only idiots need pointy clicky to get work done amirite

2013-09-18T17:32:56 < dongs> So what’s all this complexity I keep referring to? Take a look at this diagram I finger-scribbled on my iPad - it’s how the old IDE worked:

2013-09-18T17:37:32 <+Steffanx> that guy sounds like that guy from photonvidzzz Laurenceb
2013-09-18T17:37:39 < gxti> if i want to do something like "transfer up to  100 bytes from uart", is there a clever way to do that? i was thinking just setting a timer that would trigger after 100 bytes should have been transferred, and if DMA isn't complete by then then just stop DMA
2013-09-18T17:38:41 < Laurenceb> http://www.youtube.com/watch?v=CArIva4neMs&feature=player_detailpage#t=149
2013-09-18T17:38:43 < Laurenceb> ^rofl

2013-09-18T17:39:17 <+Steffanx> ^^ troll
2013-09-18T17:40:10 <+Steffanx> Wouldn't DMA transfer everything no matter what.. or give an error gxti?
2013-09-18T17:40:49 < gxti> it will just sit there until 100 bytes have been transferred, even if it takes 10 minutes. i want it to time out if there isn't 100 with no delay.
2013-09-18T17:41:18 < dongs> oh is that how it worksr?
2013-09-18T17:41:27 < dongs> i guess character receive will trigger one dma copy?
2013-09-18T17:41:34 < gxti> yes
2013-09-18T17:41:56 < gxti> dma is wired to each peripheral so the peripheral notifies DMA when stuff is there and DMA notifies peripheral once it's grabbed it, just like an interrupt would do
2013-09-18T17:42:53 < gxti> anyway i'm pretty sure this will work, just wondering if anyone had tried before
2013-09-18T17:43:23 < dongs> if you have timers free, you can just register a callback on a timer complete, start the timer in dma receive begin, then callback will stop DMA after xx timeout?
2013-09-18T17:43:29 < gxti> RTFMing now since i've never done DMA myself before, just chibios doing it for me
2013-09-18T17:43:41 < gxti> yep
2013-09-18T17:43:55 < dongs> timer complete =  like output compare or somethin.

2013-09-18T17:50:25 <+Steffanx> You want to to tx timeouts not gxti?
2013-09-18T17:50:29 <+Steffanx> or also rx?
2013-09-18T17:50:44 < gxti> Steffanx: just rx, because i don't know how many bytes will be sent. it's packets of crap from gps receiver.
2013-09-18T17:50:52 < gxti> tx is easy because i know how many bytes i'm sending.
2013-09-18T17:51:18 <+Steffanx> You did see the document about a DMA fifo thing + rx timeout?
2013-09-18T17:51:51 < dongs> gxti: you have tasks right...
2013-09-18T17:51:55 < dongs> why are you worried about timeouts?
2013-09-18T17:52:09 < dongs> gpstask() { while (serialavailable()) { readsomebytes+parse }
2013-09-18T17:52:14 <+Steffanx> :P
2013-09-18T17:52:16 < dongs> your serial driver fills in a fifo w/gps trash
2013-09-18T17:52:34 < dongs> well, while(1) around that.
2013-09-18T17:52:36 < dongs> bu you get the idea
2013-09-18T17:52:38 < gxti> yeah i'm just seeing if i can use DMA to make the cpu not have to do all that crap
2013-09-18T17:52:52 < dongs> you dont need to
2013-09-18T17:52:59 < dongs> serial puts stuff in buffer wiht dma
2013-09-18T17:53:06 < gxti> that's a lot of time wasted doing context switching just to receive 1 byte
2013-09-18T17:53:11 < dongs> not one byte
2013-09-18T17:53:29 < dongs> while you're parsing shit more junk w ill be in fifo
2013-09-18T17:54:38 < gxti> it doesn't really make a difference whether it's driven by a timeout or by a thread, both work and it's pretty much the same shit
2013-09-18T17:54:50 < dongs> hokay. just sayin.
2013-09-18T17:56:41 < Laurenceb> i used dma for this

2013-09-18T18:38:47 < karlp> so why try and get rx dma to work?
2013-09-18T18:39:01 < gxti> because i can, and because the DMA doesn't have anything better to do while the CPU does

2013-09-19T05:31:51 < gxti> just the part number, naturally
2013-09-19T05:32:52 < gxti> i also like how all the comments A) didn't notice it's not 3600mAh and B) are all using it for vaporizers
2013-09-19T05:35:01 < dongs> vaporizer = stoner shit?
2013-09-19T05:35:12 < dongs> so wehre's the surprise they didnt notice

2013-09-19T15:34:56 < dongie> Posterdati: it would be, but analog sensors have bandwidth limits too
2013-09-19T15:35:30 < Posterdati> dongie: yes, but higher bandwidth
2013-09-19T15:35:46 < dongie> depends on device.
2013-09-19T15:35:51 < Posterdati> yes
2013-09-19T15:39:39 < Robint91> Posterdati, I do like the ST device stack

2013-09-19T16:25:38 < zyp> jpa-, I checked the specs, the reason ACM isn't supported on LS is because LS can't have bulk endpoints
2013-09-19T16:26:07 < zyp> LS is interrupt and control only
2013-09-19T16:28:34 < zyp> and CDC data class interfaces (which ACM builds on) can be either bulk or isochronous
2013-09-19T16:30:41 < zyp> http://www.recursion.jp/avrcdc/ <- this works by having the host violate spec and do bulk on LS
2013-09-19T16:31:09 < zyp> otherwise I guess you could violate CDC spec and use interrupt endpoints
2013-09-19T16:31:46 < Robint91> zyp, doesn't V-USB violate the usb specs
2013-09-19T16:31:49 < Robint91> in any case
2013-09-19T16:32:05 < zyp> either way it won't work with standard hosts, and thus lack the "out of the box"-advantage of ACM in the first place
2013-09-19T16:32:14 < zyp> Robint91, dunno, does it?
2013-09-19T16:32:36 < Robint91> zyp, I thougth it does by default
2013-09-19T16:33:19 < zyp> it claims to be compliant except for error handling and electrical specifications
2013-09-19T16:35:26 < Robint91> zyp, that thing is out dated because there are everywhere usb mcu's
2013-09-19T16:35:45 < zyp> Robint91, that's beside the point
2013-09-19T16:36:25 < Robint91> zyp, the only thing you can do is HID with that thing, CDC is trail and error
2013-09-19T16:37:05 < Robint91> zyp, I haven't seen a  usb device certified with that lib
2013-09-19T16:37:30 < zyp> I'm not sure what point you're trying to make, I have no plans about using v-usb
2013-09-19T16:37:43 < zyp> we were just discussing why ACM can't be used on LS devices
2013-09-19T16:37:56 < Robint91> zyp, one should use that lib
2013-09-19T16:38:25 < Robint91> no *
2013-09-19T16:38:36 < zyp> ok
2013-09-19T16:38:44 < zyp> then don't.
2013-09-19T16:38:57 < Robint91> but on the LS part
2013-09-19T16:39:18 < Robint91> does that work on everyhost and every OS?
2013-09-19T16:39:43 < zyp> no, ACM on LS is not possible according to specs
2013-09-19T16:39:52 < zyp> 15:26:06 < zyp> LS is interrupt and control only
2013-09-19T16:39:52 < zyp> 15:28:34 < zyp> and CDC data class interfaces (which ACM builds on) can be either bulk or isochronous
2013-09-19T16:40:10 < Robint91> I think it is a driver limitation, instead of hardware
2013-09-19T16:40:52 < zyp> it's a spec limitation
2013-09-19T16:41:24 < zyp> how much of it is a hardware limitation depends on the hardware implementation
2013-09-19T16:44:48 < jpa-> yeah, you can of course make a CDC-like interface yourself and make a custom driver for it, but it won't be CDC anymore

2013-09-19T17:42:50 < emeb_mac> Ah

2013-09-19T17:44:00 < emeb_mac> Mathworks has a lot of backends to convert to various languages - C/C++, Verilog, VHDL, etc
2013-09-19T17:44:19 < emeb_mac> don't think I've ever heard anyone say good things about the results.
2013-09-19T17:44:41 < emeb_mac> it's mainly for situations where you're in a hurry and don't care about bloat
2013-09-19T17:45:07 < emeb_mac> (ie can afford high-end hardware that can run the output)

2013-09-19T19:34:17 < ouah> zyp: ST lib has a function defined with __attribute__((section(".data")))
2013-09-19T19:34:27 < ouah> in /stm32l1xx_flash_ramfunc.c
2013-09-19T19:34:54 < ouah> the idea for them is to have the function executed in RAM
2013-09-19T19:35:01 < zyp> and you're simply trying to build it, or reuse it?
2013-09-19T19:35:24 < ouah> zyp: I'm building it, no change
2013-09-19T19:35:43 < zyp> because what I would do is rather make a .text_ram section, but that would require the addition of more stuff to handle it
2013-09-19T19:36:18 < ouah> I would prefer not to modify their library actually
2013-09-19T19:37:08 < zyp> but, that's just a warning, not an error?
2013-09-19T19:37:41 < ouah> yes but I do not tolerate warnings;)
2013-09-19T19:38:41 < zyp> then you should not use shitty libs ;)
2013-09-19T19:38:53 < zyp> so, anyway
2013-09-19T19:39:06 < zyp> how do you expect to solve it without modifying the code?
2013-09-19T19:39:49 < zyp> because stuffing executable code into a nonexecutable section sounds like a good reason for a warning to me :p
2013-09-19T19:40:13 < ouah> zyp: my linker script marks .data as executable
2013-09-19T19:40:42 < zyp> sure, but that's only for the .data that the linker outputs
2013-09-19T19:41:31 < ouah> I know but in that case it's not a good reason for the compiler to yell
2013-09-19T19:42:36 < zyp> why not? the compiler creates a section .data that it's going to use for variables, and then you suddenly stuff executable code into it
2013-09-19T19:44:19 < ouah> I'm looking for an option to pass to the compiler for either take a look at the linker script or silence the warning
2013-09-19T19:45:50 < zyp> which gcc version are you using?
2013-09-19T19:46:22 < ouah> 4.7.3 from GNU Tools
2013-09-19T19:46:27 < zyp> ok, good
2013-09-19T19:46:59 < ouah> ST should not put their code into a library if I need to modify the lib to fix their warning
2013-09-19T19:47:17 < ouah> I may redefine the function to get rid of the warning
2013-09-19T19:55:22 < GargantuaSauce> is it possible that .data is actually the default section for code and that's why it's being ignored?
2013-09-19T19:57:36 < ouah> I think the default section for code is .text, i.e., executes from flash
2013-09-19T19:58:34 < karlp> it's not a librayr, it's a bunch of source you're meant to drop into your project
2013-09-19T19:58:38 < karlp> apparently that's how pros work

2013-09-20T02:10:41 < zyp> if whatever gdbserver you're using supports the threading stuff you're using, you can do stuff like «info threads» and «thread 5»
2013-09-20T02:11:28 < gxti> apparently it does not, not a big surprise.

2013-09-20T07:14:29 < dongs> needs more knobs
2013-09-20T07:14:49 < ds2> are those pots or quad encoders?
2013-09-20T07:14:52 < emeb_mac> it's got lots of knobs.
2013-09-20T07:15:12 < emeb_mac> the one in the lower left is an encoder. all the others are pots
2013-09-20T07:16:30 < ds2> how does the f303 sees the pots?
2013-09-20T07:17:22 < emeb_mac> the pots sum via op-amps with voltages that come in from the jacks on the right side. The sums go to the F303 ADC inputs.
2013-09-20T07:17:35 < emeb_mac> 8 total ADC inputs.
2013-09-20T07:17:41 < emeb_mac> 2 from each row
2013-09-20T07:19:48 < emeb_mac> F303 uses the 2 ADC inputs to generate an audio waveform (frequency, waveshape).
2013-09-20T07:20:14 < emeb_mac> four waves go out 2x stereo I2S DACs to four jacks on far right.
2013-09-20T07:20:26 < ds2> emeb_mac: what does the f303 do?
2013-09-20T07:21:04 < emeb_mac> ds2: reads the 8 ADC inputs, does DSP to generate the four channel audio outputs.
2013-09-20T07:21:28 < dongs> emeb_mac: quickly, implement dolby NR on F303 now that dolby guy is dead
2013-09-20T07:22:08 < emeb_mac> har
2013-09-20T07:22:30 < emeb_mac> could probably do it for the original dolby B/C tape noise reduction.
2013-09-20T07:22:41 < emeb_mac> that was just compression and equalization.
2013-09-20T07:23:41 < emeb_mac> the newer multichannel 3D audio stuff is probably to complex for the F303 though
2013-09-20T07:25:42 < dongs> is that a SPI lcd there

2013-09-20T07:27:55 < dongs> add dip sockets for opamps on the back then
2013-09-20T07:28:09 < emeb_mac> that'll make it so much better.
2013-09-20T07:28:35 < emeb_mac> don't laugh though - there are audiophools who believe that DIP vs SMT makes a difference in the sound.

2013-09-20T07:35:37 < ds2> probally based on that malaxis sensor
2013-09-20T07:36:31 < jef79m> estimated delivery may 2013. update 6 days ago: starting on the software part that actually does the thermal image.
2013-09-20T07:36:50 < emeb_mac> success because iPhone
2013-09-20T07:37:05 < ds2> what they didn't quote is how wide of a field of view
2013-09-20T07:37:17 < emeb_mac> looks pretty narrow
2013-09-20T07:37:29 < ds2> narrow is good
2013-09-20T07:37:37 < ds2> wide is easy to do
2013-09-20T07:38:27 < ds2> wonder if they actually have a FIR lens
2013-09-20T07:41:30 < emeb_mac> yeah - not much detail.

2013-09-20T14:40:36 < dongs> apparently M0 doesnt
2013-09-20T14:40:36 < dongs> i was surprised too

2013-09-20T14:44:00 < jpa-> yeah, probably open sores ruined it
2013-09-20T14:45:02 < talsit> crap
2013-09-20T14:45:15 < jon1012> ?
2013-09-20T14:45:21 < talsit> how do i get the number of clock cycles on a 051?
2013-09-20T14:45:31 < jpa-> talsit: set up a timer to count them?
2013-09-20T14:45:55 < talsit> there's no native support for that?!
2013-09-20T14:46:01 < talsit> boooooo
2013-09-20T14:46:02 < jpa-> native?
2013-09-20T14:46:06 < talsit> register
2013-09-20T14:46:12 < jpa-> sure, the timers have registers..
2013-09-20T14:46:24 < talsit> as in, something *like* the DWT_CYCCNT register
2013-09-20T14:46:34 < jpa-> TIMx->CNT?
2013-09-20T14:46:44 < talsit> without setting up a timer
2013-09-20T14:46:51 < jpa-> you have to set up the DWT anyway
2013-09-20T14:47:09 < jpa-> so what's the difference if you set up DWT or a timer?
2013-09-20T14:47:22 < jpa-> only downside is that you have to spend one timer on that crap
2013-09-20T14:48:44 < talsit> hmmm... ok, i'll do that
2013-09-20T14:49:04 < jpa-> i hope that 051 has 32 bit timers or you only need 16 bits :P
2013-09-20T14:50:09 < talsit> tim2 & 3 are 16/32, by the looks of it
2013-09-20T14:50:16 < talsit> TIM2 is 32
2013-09-20T14:51:20 < talsit> now i just have to remember how the hell to do this
2013-09-20T14:51:37 < jpa-> TIMx->CR1 |= TIM_CR1_CEN;   done
2013-09-20T14:51:53 < jpa-> ok ok.. APB clocks and all that shit

2013-09-20T14:53:53 < dongs> DWT stops when youre stepping
2013-09-20T14:53:53 < dongs> and its the CYCLE counter
2013-09-20T14:54:29 < jpa-> yeah, and on faster processors DWT may run at higher clock rate and DWT also does a lot more than cycle counting etc.
2013-09-20T14:55:00 < jpa-> but i mean, he will need to setup something, so just setup a timer because that's quite much all that F0 has :P

2013-09-20T15:07:00 < talsit> you know how to enable RXM-RAW, RXM-SFRB msg in the ublox6?
2013-09-20T15:07:25 < dongie> wouldnt this be public info?
2013-09-20T15:07:43 < talsit> on, on the non-timer modules
2013-09-20T15:07:45 < talsit> so lea-6h
2013-09-20T15:07:50 < talsit> not lea-6t
2013-09-20T15:08:01 < dongie> why not just get 6T insetad?
2013-09-20T15:08:31 < talsit> 1) a lot more expensive; 2) i have a bunch of 6H already
2013-09-20T15:08:43 < dongie> have you considered that its firmware limitation, which is in mask rom?
2013-09-20T15:09:32 < talsit> i have considered that, but i have also read that it can be enabled, according to this site: http://wiki.openstreetmap.org/wiki/RTKLIB#Inofficially_supported_hardware
2013-09-20T15:10:14 < talsit> anyway, dinner time
2013-09-20T15:10:16 < dongie> yes. 6M which is flash based.
2013-09-20T15:10:20 < dongie> H = mask rom
2013-09-20T15:10:25 < dongie> you can probably flash some hax0r firmware into 6M
2013-09-20T15:10:34 < talsit> H is flash
2013-09-20T15:12:13 < dongie> hokay.

2013-09-20T20:24:59 < jpa-> i.e. does it have your config listed there
2013-09-20T20:26:55 < kuldeepdhaka> http://pastebin.ca/2455569      im using -mfloat-abi=hard -mfpu=fpv4-sp-d16   (looks like it does contain)
2013-09-20T20:28:28 < jpa-> kuldeepdhaka: hmm.. do you remember to pass the same flags to the linker also?

2013-09-20T20:30:35 < jpa-> uh.. why -lnosys?

2013-09-20T20:30:52 < jpa-> forget
2013-09-20T20:30:59 < jpa-> of course -lnosys :)
2013-09-20T20:31:17 < jpa-> but why are you puttin the toolchain dirs using -L manually?
2013-09-20T20:32:13 < jpa-> that kind of bypasses multilib and causes gcc to use the wrong version of libc
2013-09-20T20:33:10 < kuldeepdhaka> jpa-, yes, you are right.
2013-09-20T20:33:26 < kuldeepdhaka> i removed the  -L$(TOOLCHAIN_DIR)/lib/stm32/f4   -L$(TOOLCHAIN_DIR)/lib \ part and it worked
2013-09-20T20:33:52 < kuldeepdhaka> i borrowed CFLAGS and LDFLAGS from one of the libopencm3 example

2013-09-20T20:36:17 < jpa-> now i just wish Steffanx would save my night :P
2013-09-20T20:37:11 < Thorn> the path, /usr/bin/../arm-none-eabi/lib/libc.a, didn't look right (should contain lib/armv7e-m/fpu or something like that with multilib iinm)

2013-09-20T23:45:53 < gxti> dongs: dongie: it's pretty trivial, see page 3: http://hg.partiallystapled.com/circuits/laureline/raw-file/b16d2a51a3cd/hw/out/production.PDF
2013-09-20T23:46:35 < gxti> most of it is for powering the external antenna, you can remove all that shit if your antenna is unpowered
2013-09-20T23:49:54 < upgrdman> why would an antenna needs power? pre-amp?
2013-09-20T23:50:01 < gxti> yep
2013-09-20T23:50:32 < gxti> anytime you have more than a few inches of cable you need it
2013-09-20T23:50:57 < upgrdman> o ok
2013-09-20T23:51:19 < gxti> it's to compensate for cable loss, not to boost the received signal per se
2013-09-20T23:51:24 < upgrdman> are pre-amps usually selective, or amp everything?
2013-09-20T23:51:28 < upgrdman> ya
2013-09-20T23:52:04 < gxti> depends on the antenna, most are just L1 "band", expensive ones are multi-band

2013-09-21T03:16:13 < dongs> Vias under ICs are deprecated, but I've certainly done my share of PCB layouts with them.

2013-09-21T05:49:39 < R2COM> I think I know this guy
2013-09-21T05:49:48 < R2COM> he hangs out on another channel
2013-09-21T05:50:10 < dongs> lol
2013-09-21T05:50:20 < dongs> gym channel?
2013-09-21T05:50:29 < R2COM> nah, fpga and oshpark
2013-09-21T05:50:31 < emeb> spacex channel
2013-09-21T05:50:43 < emeb> lol oshpark has a channel
2013-09-21T05:50:58 < dongs> right so he knows nothing about either PCB manufacture or FPGA
2013-09-21T05:51:02 < emeb> everyone chants "we love the purple"
2013-09-21T05:51:47 < R2COM> actually, he is good at fpga related design as far as I remember
2013-09-21T05:52:44 < R2COM> i personally hang out there mainly to keep in touch with guy who runs batches

2013-09-21T06:01:19 < R2COM> looking
2013-09-21T06:02:04 < R2COM> I done imager on IC level once, although it never got fabbed. just simulated it.
2013-09-21T06:02:31 < R2COM> ok
2013-09-21T06:02:37 < R2COM> so he basically builds thermal imager
2013-09-21T06:02:45 < R2COM> and he claims that his 300$ shit is better than industrial one
2013-09-21T06:02:54 < R2COM> there are very good ones, if I am correct from Fluke

2013-09-21T06:03:44 < R2COM> choice
2013-09-21T06:04:15 < dongie> wow those fluke things are aroudn 500-600bucks on ebay

2013-09-21T06:05:33 < R2COM> so again I am not sure how did he get 282$k
2013-09-21T06:05:38 < R2COM> because of Iphone?
2013-09-21T06:05:41 < R2COM> and open sores?
2013-09-21T06:05:52 < dongs> yes
2013-09-21T06:05:55 < dongs> but thats not the best pa rt
2013-09-21T06:06:01 < dongs> the entier campaign is a troll
2013-09-21T06:06:07 < dongs> he has nothing to show working
2013-09-21T06:06:08 < dongs> at all
2013-09-21T06:06:15 < gxti> eevblog has a nice thread on it
2013-09-21T06:06:18 < dongs> right
2013-09-21T06:06:22 < gxti> in the "crowd funding" section
2013-09-21T06:06:32 < dongs> its like the 1st hit when doing muoptics scam on google
2013-09-21T06:06:36 < dongs> (eevblag threaD)
2013-09-21T06:07:48 < R2COM> nice

2013-09-21T06:11:34 < R2COM> they apply for patent
2013-09-21T06:11:35 < R2COM> hehe
2013-09-21T06:11:44 < R2COM> applying patent today in US is all about money
2013-09-21T06:11:45 < dongs> patent on trolling
2013-09-21T06:11:58 < R2COM> its not like long time ago, when you had to show real working thing
2013-09-21T06:12:09 < dongs> R2COM: whats the thermal imager rez on that fluke
2013-09-21T06:12:10 < R2COM> today you can just patent idea, with some brief description
2013-09-21T06:12:15 < dongs> sounds like the sensor about the size of IR-BLUE
2013-09-21T06:12:18 < dongs> i.e. 64dots or somethign
2013-09-21T06:12:47 < R2COM> not sure
2013-09-21T06:13:18 < dongs> hmm
2013-09-21T06:13:54 < R2COM> its key parameters as meas. range and accuracy listed though
2013-09-21T06:13:58 < R2COM> and field of view
2013-09-21T06:14:41 < R2COM> http://www.newark.com/jsp/search/productdetail.jsp?SKU=57T9458&CMP=KNC-GPLA&mckv=|pcrid|27090000261|plid|
2013-09-21T06:14:45 < R2COM> 2200$
2013-09-21T06:14:50 < R2COM> 160x120 resolution
2013-09-21T06:15:02 < R2COM> but sensitivity is reall good, 0.2C
2013-09-21T06:15:08 < R2COM> whcih is why I guess its more expencive
2013-09-21T06:15:35 < dongs> thats beacuse that one is a microbolometer
2013-09-21T06:15:51 < dongs> i wanna more info on this Uncooled Hyperthin Pyroelectric Ceramic shit
2013-09-21T06:15:54 < dongs> which is in the cheap fluke
2013-09-21T06:16:25 < R2COM> uncolled sensors usually used in thermal part of seeker in missiles nowadays.
2013-09-21T06:16:57 < dongs> um, pretty much anything modern is uncooled
2013-09-21T06:16:59 < dongs> tahts not the question

2013-09-21T07:44:29 < emeb_mac> wtf?
2013-09-21T07:45:06 < dongs> hm explorer 16 is microchip trash
2013-09-21T07:45:10 < dongs> so they're using fucking dspic for that
2013-09-21T07:45:12 < dongs> fucking aidssssssssssss
2013-09-21T07:45:28 < R2COM> world changing starting from today
2013-09-21T07:45:35 < R2COM> lets start stackup trash one on top of another
2013-09-21T07:45:46 < ds2> is the dspic the MIPS thing?
2013-09-21T07:45:48 < emeb_mac> it's trash all the way down
2013-09-21T07:46:03 < emeb_mac> ds2 PIC32 is MIPS
2013-09-21T07:46:09 < ds2> ah right
2013-09-21T07:46:13 < dongs> no dspic is just 16bit trash
2013-09-21T07:46:15 < emeb_mac> dsPIC and PIC24 are their own thing

2013-09-21T07:46:45 < R2COM> killer engineering team
2013-09-21T07:46:49 < emeb_mac> dsPIC is a pretty nice architecture from an assembly standpoint.
2013-09-21T07:46:55 < emeb_mac> I used it for years happily
2013-09-21T07:46:55 < ds2> why do people still waste their time with microchip crap thesedays?
2013-09-21T07:47:08 < emeb_mac> cause it's cheap
2013-09-21T07:47:09 < dongs> who knows
2013-09-21T07:47:12 < dongs> its not
2013-09-21T07:47:13 < emeb_mac> and it's legacy
2013-09-21T07:47:16 < dongs> development time isn't cheap
2013-09-21T07:47:17 < emeb_mac> been around for ages
2013-09-21T07:47:49 < emeb_mac> MCHP has relationships with a lot of consumer electronics outfits that go back for decades
2013-09-21T07:47:54 < ds2> aren't there cheaper options?
2013-09-21T07:48:02 < emeb_mac> probably
2013-09-21T07:48:03 < ds2> like all those 8051s around
2013-09-21T07:48:05 < ds2> or the m0's
2013-09-21T07:48:18 < emeb_mac> but MCHP customizes their stuff for specific markets like no other company

2013-09-21T07:48:23 < dongs> wtfaka
2013-09-21T07:48:29 < R2COM> first of all
2013-09-21T07:48:33 < R2COM> microchip is american trash
2013-09-21T07:48:38 < ds2> OooooooH
2013-09-21T07:48:53 < R2COM> and some maybe defense contractors would feel more comfortable putting it in their shit rather than that french italian stuff
2013-09-21T07:48:55 < R2COM> from st
2013-09-21T07:49:06 < R2COM> and not only defense
2013-09-21T07:49:08 < dongs> ha ha
2013-09-21T07:49:11 < dongs> you mean
2013-09-21T07:49:11 < R2COM> thats one of the reasons
2013-09-21T07:49:15 < dongs> microchip has all the NSA backdoors
2013-09-21T07:49:20 < dongs> so they feel right at home
2013-09-21T07:49:26 < R2COM> not sure about all
2013-09-21T07:49:30 < R2COM> but they have some probably
2013-09-21T07:49:33 < emeb_mac> I'd be _really_ surprised to see MCHP in any defense / hi-rel apps that require NOFORN
2013-09-21T07:49:49 < emeb_mac> it's just not built to that standard.
2013-09-21T07:49:57 < dongs> what do the nigs use then
2013-09-21T07:50:01 < R2COM> i did not say to use it in space or something
2013-09-21T07:50:12 < R2COM> there are different requirements for different stuff related with defense
2013-09-21T07:50:14 < emeb_mac> I see it mostly in cheap white goods (toasters, light switches, blood-pressure meters, etc)
2013-09-21T07:50:21 < dongs> http://www.kickstarter.com/projects/wildhelp/wildhelp-app?ref=category  FAIL
2013-09-21T07:50:26 < R2COM> yes industry too
2013-09-21T07:51:42 < ds2> there are all the TI crap
2013-09-21T07:51:51 < emeb_mac> anyway, dsPIC was great for DSP about 6-7 years ago. Kinda behind the curve now.
2013-09-21T07:52:17 < emeb_mac> ds2: I know a lot of OMAP stuff gets used in defense work.
2013-09-21T07:52:27 < R2COM> holland stuff?
2013-09-21T07:52:36 < R2COM> nederland
2013-09-21T07:52:36 < R2COM> ?
2013-09-21T07:52:39 < ds2> emeb_mac: the 430's might be a better comparism
2013-09-21T07:52:47 < R2COM> isnt OMAP from that country or?
2013-09-21T07:53:02 < emeb_mac> TI OMAP - straight from Dallas.
2013-09-21T07:53:17 < ds2> but that has IP from the brits
2013-09-21T07:53:36 < emeb_mac> OMAP has IP from all over - probably half of it is from India these days.
2013-09-21T07:53:55 < dongs> lol indian IP
2013-09-21T07:54:08 < R2COM> so
2013-09-21T07:54:08 < ds2> is it really indian IP or just indian TI folks doing the IP?
2013-09-21T07:54:13 < R2COM> indian stuff in US defense?
2013-09-21T07:54:16 < emeb_mac> ds2: that
2013-09-21T07:54:33 < ds2> but the UK IP is really from UK not TI
2013-09-21T07:54:39 < R2COM> ?
2013-09-21T07:54:44 < emeb_mac> ds2: you mean the ARM IP
2013-09-21T07:54:57 < ds2> yes, the acorn stuff
2013-09-21T07:55:08 < emeb_mac> probably doesn't matter who owns the rights as long as it's made by a US company.
2013-09-21T07:55:16 < R2COM> haha
2013-09-21T07:55:32 < R2COM> it matters when something happens you know ;)
2013-09-21T07:55:41 < R2COM> on the long run
2013-09-21T07:56:20 < ds2> that acorn stuff is (AFAIK) not provided in a clear manner to the chip makers
2013-09-21T07:56:45 < emeb_mac> ds2: there are different levels of licensing

2013-09-21T07:57:06 < emeb_mac> when I worked at Intel they had a very broad license due to the XScale stuff.
2013-09-21T07:57:07 < ds2> hmmm
2013-09-21T07:57:24 < emeb_mac> they had access to source code & could tweak the guts of the ARM parts if they wanted to.
2013-09-21T07:57:36 < dongs> yeah, it depends what level you're at
2013-09-21T07:57:38 < emeb_mac> not just hard macros plopped down on silicon.
2013-09-21T07:57:41 < dongs> you can get hdl sores or just binary etc.
2013-09-21T07:57:46 < ds2> yes Xscale is different
2013-09-21T07:57:52 < dongs> apple for example
2013-09-21T07:58:03 < ds2> xscale is strongarm fucked up
2013-09-21T07:58:14 < dongs> they have sores license, so tehy haxed together whatever that dual core A8 or A15 or whatever trash in A7
2013-09-21T07:58:20 < emeb_mac> and now Marvell owns it.
2013-09-21T07:58:40 < emeb_mac> Intel has declared ARM the enemy and will only do Atom stuff for embedded.

2013-09-21T08:36:20 < dongs> i think
2013-09-21T08:36:57 < emeb_mac> dongs: that's a proto for something that's already destined for production.
2013-09-21T08:37:15 < dongs> doesnt stop you from dickstarting it
2013-09-21T08:37:23 < dongs> then when you reach goal, manufacturer comes and says you stole their design
2013-09-21T08:37:26 < dongs> then you just pocket money
2013-09-21T08:37:27 < dongs> done
2013-09-21T08:37:47 < emeb_mac> he'd probably do a ks before I would
2013-09-21T08:43:56 < ds2> anyone here actually milled PCBs before?
2013-09-21T08:44:20 < dongs> prety sure most people don't waste time like that

2013-09-21T08:45:47 < dongs> ds2: and yuou get a board w/mask and working vias
2013-09-21T08:45:49 < dongs> not worth it.
2013-09-21T08:46:00 < dongs> can't imagine anything that needs to be testable in 3 hours that you cant wait at least a day for.
2013-09-21T08:46:20 < emeb_mac> probably even faster to do a 2-sided home-etch.
2013-09-21T08:46:35 < ds2> really?. you get get stuck with ``we need this demo thing by the end of the week'' jobs?
2013-09-21T08:46:52 < emeb_mac> but on the plus side, an LPKF makes a lot of noise and dust!
2013-09-21T08:47:12 < ds2> I don't think I have seen a home etch for for stuff finer then 0.050"
2013-09-21T08:47:41 < emeb_mac> ds2: dong's favorite guy in the world - DJ Delorie - does it all the time.
2013-09-21T08:48:06 < ds2> emeb_mac: for the finer pitch stuff?
2013-09-21T08:48:49 < emeb_mac> ds2: pretty sure I've seen him post pix of home-made boards good for .5mm pitch
2013-09-21T08:49:07 < ds2> I see
2013-09-21T08:49:19 < emeb_mac> granted - not everyone is set up for that. I wouldn't try it.
2013-09-21T08:49:27 < emeb_mac> Plus, no vias is a pain.
2013-09-21T08:50:07 < dongs> i can get professionally fabbed 2-6 layer shit in 24 hours if I  was really stuck with "we ned this demo by weekend" shit.
2013-09-21T08:50:19 < dongs> but chances are, if its that tight, you're probably fucked already anyway.
2013-09-21T08:50:26 < emeb_mac> that
2013-09-21T08:50:29 < dongs> and no home milling is gonna save you
2013-09-21T08:51:06 < dongs> home wmilling will work if your demo is a tarduino shield.
2013-09-21T08:52:25 < dongs> lol just noticed dj delorie dig
2013-09-21T08:52:28 < dongs> that guy is a nutcase
2013-09-21T08:59:14 < dongs> meh
2013-09-21T08:59:17 < dongs> R2COM: your fluke thing is trash
2013-09-21T08:59:17 < dongs> Whilst this is not a thermal imaging camera, the VT02 does feature a 15 x 15 pixel thermal detector. This feature enables you to view a digital image of the object and shows up any hotspots. With a standard infrared thermometer, you would need to take multiple measurements to get a good reading. The benefit of the VT02 means you can see instantly where the hotspots are and investigate further.
2013-09-21T09:02:06 < R2COM> well
2013-09-21T09:02:11 < R2COM> look up next more expencive model then

2013-09-21T13:26:43 <+Steffanx> nervouseness?!
2013-09-21T13:26:56 <+Steffanx> I really just don't give a shit about what you don't see.
2013-09-21T13:27:19 < R2COM> so?
2013-09-21T13:27:24 <+Steffanx> You want to say that the few technical things you say make your bullshit 'legal'?
2013-09-21T13:27:27 < R2COM> doesnt change anything.
2013-09-21T13:27:43 <+Steffanx> I didn't see any rule about that when i joined this channel.
2013-09-21T13:28:35 < R2COM> nope. I'm saying that person who has so much against bs posted by other people maybe should post himself something worth interesting looking at rather than complaining
2013-09-21T13:28:45 < R2COM> and if he doesnt
2013-09-21T13:28:56 < R2COM> he should just maybe not start this talk

2013-09-21T14:25:16 < Thorn> with openocd you may be able to write a tcl script
2013-09-21T14:28:03 < Thorn> or hack the  bmp and add a monitor commanf to display the id

2013-09-21T14:57:53 <+Steffanx> The stuff you get when you instll the stlink utility.
2013-09-21T14:58:13 < dongs> i dont think that has anything gdb related.
2013-09-21T14:58:18 < dongs> at least it didnt 2-3 years ago when i alst tried
2013-09-21T14:58:20 <+Steffanx> That includes a gdb server iirc.

2013-09-21T15:00:25 <+Steffanx> hmm, so what gdb server did use on windows once. Im sure it was not texane
2013-09-21T15:00:43 < dongs> atollic has one
2013-09-21T15:01:00 <+Steffanx> i guess that was the one.

2013-09-21T15:36:09 < dongs> also now you have no way to tell if streetview is avilable in a certain area or not
2013-09-21T15:36:35 < dongs> before you drop the little dude on a map and it overlayed areas w/view
2013-09-21T15:36:35 < dongs> now its just ???
2013-09-21T15:36:35 < dongs> you click and if youre lucky it'll show stretview button.

2013-09-21T15:38:17 <@Tectu> what is that gay 3D view when you zoom in?
2013-09-21T15:38:23 <@Tectu> how do I turn that off?
2013-09-21T15:38:45 < jpa-> it's the new google gaydar
2013-09-21T15:38:56 < jpa-> it's only enabled if google has detected a gay person using the computer

2013-09-21T15:45:10 < dongs> so i guess you cant link to streetview shit directly now?

2013-09-21T15:46:14 < dongs> you dont see the printer im pointing to tho.
2013-09-21T15:46:30 < dongs> ifnact its not even anywhere near the printer.
2013-09-21T15:46:39 < dongs> ithink its just generic start point for that map.

2013-09-21T15:47:16 <+Steffanx> what is that?

2013-09-21T16:26:48 < Laurenceb__> yup
2013-09-21T16:26:51 < Laurenceb__> unfortunatly
2013-09-21T16:26:57 < Laurenceb__> but it gets the job done
2013-09-21T16:27:01 <+Steffanx> its bit slower, but is it that bad?

2013-09-21T17:07:11 < dongs> horrible.
2013-09-21T17:07:31 <+Steffanx> kinda.
2013-09-21T17:09:51 < emeb_mac> don't use Octave much. Mostly Matlab. Octave is OK for small stuff.
2013-09-21T17:10:21 < Thorn> scilab.
2013-09-21T17:11:44 < emeb_mac> Matlab plot windows are a lot nicer - zoom, pan, marking points, printing/saving.
2013-09-21T17:12:59 < emeb_mac> I've got a license for Simulink & a couple of toolboxes but I rarely use it now.
2013-09-21T17:12:59 < dongs> exporting to PDF
2013-09-21T17:14:29 < emeb_mac> Matlab is funny - now and then I'll do something dumb and it tries to create a matrix larger than memory. Fun trying to recover from that.
2013-09-21T17:14:38 < dongs> tor> As of 2003, it was estimated that 1 billion units are manufactured every year.
2013-09-21T17:14:41 < dongs> ^ 555 timers
2013-09-21T17:15:00 < emeb_mac> that was 10yrs ago - wonder what it is now.
2013-09-21T17:25:45 < zyp> way less
2013-09-21T17:26:18 < emeb_mac> likely
2013-09-21T17:27:30 < emeb_mac> so here's something cute: one of my "competitors" in the audio/synth world has a module out that uses an F303...
2013-09-21T17:28:05 < emeb_mac> it can update its firmware by playing an audio file into it - apparently uses FSK or something.
2013-09-21T17:28:24 < emeb_mac> firmware updates distributed as sound file...
2013-09-21T17:29:06 < zyp> I think we talked about doing that once
2013-09-21T17:31:13 < Robint91> what sane peeps do stuff like that
2013-09-21T17:31:14 < emeb_mac> aaand it's open source: https://github.com/pichenettes/eurorack/blob/master/braids/bootloader/bootloader.cc
2013-09-21T17:31:23 < emeb_mac> not an F303 - F10x
2013-09-21T17:32:00 < Robint91> they should be hung
2013-09-21T17:33:46 <+Steffanx> Why you can update the firmware by playing some music.
2013-09-21T17:33:59 < Robint91> emeb_mac, is this a example of "good" code?
2013-09-21T17:34:08 < emeb_mac> Robint91: no idea.
2013-09-21T17:34:09 <+Steffanx> It sounds nice to me..
2013-09-21T17:34:40 < emeb_mac> apparently it works. what more do you want?
2013-09-21T17:34:46 < Robint91> what is the problem with DFU?
2013-09-21T17:34:56 <+Steffanx> USB?
2013-09-21T17:34:59 < Robint91> yep
2013-09-21T17:35:03 < emeb_mac> well, it's an F10x so no DFU
2013-09-21T17:35:13 <+Steffanx> ( not sure how those devices are used )
2013-09-21T17:35:23 < Robint91> emeb_mac, custom usb bootloader
2013-09-21T17:35:23 < zyp> emeb_mac, nothing stops you from doing your own DFU
2013-09-21T17:35:28 < Robint91> ^  this
2013-09-21T17:35:29 < emeb_mac> true
2013-09-21T17:35:49 <+Steffanx> It does come with a usb connection?
2013-09-21T17:35:54 <+Steffanx> *connector
2013-09-21T17:35:57 < emeb_mac> no
2013-09-21T17:36:02 <+Steffanx> There you go.
2013-09-21T17:36:04 < zyp> Robint91, anyway, the main problem with DFU would be the lack of usable universal DFU software on windows
2013-09-21T17:36:19 < emeb_mac> these devices are very simple - front panel + boards bolted on. Reside in a rack.
2013-09-21T17:36:30 < emeb_mac> no access to board w/o undoing screws
2013-09-21T17:36:33 < Robint91> zyp, there are other means to do firmware uploads without doing much drivery problems in windows
2013-09-21T17:36:37 <+Steffanx> Yeah, so I like the idea of using 'sound' to do fw upgrades. :)
2013-09-21T17:36:49 < Robint91> a usb connecter isn't the cost normall
2013-09-21T17:36:50 < emeb_mac> It's a cute idea.
2013-09-21T17:36:52 < Robint91> *normally
2013-09-21T17:37:20 < zyp> Robint91, yes, but you were asking about what the problem with DFU is in particular.

2013-09-21T19:38:39 <+Steffanx> No, seems to be pretty open. As in they give is all the register info etc.
2013-09-21T19:39:15 < emeb_mac> is that the one where they provide firmware stacks for various protocols and have strange hardware methods to partition the processor load?
2013-09-21T19:39:39 < emeb_mac> so they can guarantee their code is correct even if the stuff you write to use it screws up?

2013-09-21T23:22:31 < Fornaxian> same propane tank in both pictures.

2013-09-21T23:22:47 < Fornaxian> prelim
2013-09-21T23:23:18 < Fornaxian> there is/was a heated storage room in the corner near the big tank..
2013-09-21T23:23:27 < Fornaxian> and the propane line went into the building there.
2013-09-21T23:23:59 < qyx_> at least the tank survived
2013-09-21T23:24:08 < bsdfox> your house exploded and you're sitting on IRC?
2013-09-21T23:24:10 < Fornaxian> only fire was a burning propane line and one stick of wood laying across the burning line.
2013-09-21T23:24:13 < Fornaxian> not my house.
2013-09-21T23:24:21 < Fornaxian> my house is in the background of that first picture.
2013-09-21T23:24:33 < Fornaxian> the crop production services chemical and fertilizer company exploded.

2013-09-21T23:24:58 < Fornaxian> clock in the building stopped at 4:49

2013-09-21T23:25:19 < Fornaxian> not really.
2013-09-21T23:25:25 < Fornaxian> only one ruptured container.
2013-09-21T23:25:32 < Fornaxian> we were real lucky.
2013-09-21T23:25:36 < Fornaxian> it could have been much worse.
2013-09-21T23:25:47 < Fornaxian> there were 4 full tanks of anhydrous ammonia outside the building.

2013-09-22T02:07:09 < gxti> measured the difference between dma and irq for serial transmit, 0.09% more cpu time. but the dma also has silly bugs, like whenever there's a character received, one whole transmit operation disappears. so that's out the window for now.

2013-09-22T02:08:11 < gxti> oh and ignoring that, i have to wait for TXE before starting the next operation, otherwise it stalls. which is odd, because chibios doesn't seem to have that.
2013-09-22T02:09:00 < gxti> then again, i haven't really used chibios' uart driver (which uses dma), just serial (which does not), so maybe it has the same bug. seems unlikely though.
2013-09-22T02:09:42 < zyp> the results are pointless without knowing the test case
2013-09-22T02:09:54 < qyx_> wut?
2013-09-22T02:09:57 < zyp> how many bytes per write did you do to get those results?
2013-09-22T02:09:59 < qyx_> serial uses dma, uart dont
2013-09-22T02:10:02 < qyx_> or?
2013-09-22T02:10:36 < gxti> qyx_: nope
2013-09-22T02:11:03 < gxti> zyp: pretty simple once-per-second status report type thing, dma is really overkill anyway
2013-09-22T02:11:18 < qyx_> ah
2013-09-22T02:12:59 < zyp> at short writes, dma won't have much advantage over just using the uart directly, the advantage only becomes apparent for long writes, since the cpu overhead for dma is constant with regards to the write length
2013-09-22T02:14:34 < gxti> sure. if i knew why it was being so buggy i would probably keep it anyway, because even if the raw throughput is negligible it's still a lot of needless context switches.

2013-09-22T02:18:15 < gxti> actually i guess the context switches are because i'm using a ring buffer for the irq approach, vs transmitting directly from the client buffer using dma. could transmit from client buffer using irq and then it wouldn't involve any context switches.

2013-09-22T02:18:52 < gxti> otherwise if there's more stuff to transmit than fits in the buffer, the client has to wake up every time a byte is transmitted to put another one in the buffer

2013-09-22T19:00:48 < emeb_mac> good question
2013-09-22T19:00:56 < gxti> doesn't look like it recurses
2013-09-22T19:00:59 < emeb_mac> depends on how many spheres it hits
2013-09-22T19:01:48 < gxti> ah yes it does. but you can probably unroll it.
2013-09-22T19:02:08 < gxti> or just stop recursing when you run out of stack :P
2013-09-22T19:02:48 < emeb_mac> that's what I was thinking - put a limit on the number of recursions.
2013-09-22T19:03:30 < gxti> with that scene you can barely tell if there's more than one bounce

2013-09-22T20:04:56 < Fornaxian> umm.
2013-09-22T20:05:06 < Fornaxian> people actually would pay that for a usb cable?
2013-09-22T20:05:28 < gxti> oh not this crap again
2013-09-22T20:05:36 < Fornaxian> hehe
2013-09-22T20:05:43 < Fornaxian> humor, attempt at, one each.
2013-09-22T20:05:48 < emeb_mac> there's a sucker born every minute and 2 to skin him.

2013-09-22T20:21:32 < Laurenceb__> haha
2013-09-22T20:21:35 < emeb_mac> Laurenceb__: how is it that you were mistaken for an illegal the other day?
2013-09-22T20:21:36 < Thorn> the level of activity in the openvizsla github does not seem encouraging
2013-09-22T20:21:45 < Laurenceb__> emeb_mac: got raided at work
2013-09-22T20:21:53 < emeb_mac> ya saw that.
2013-09-22T20:22:06 < emeb_mac> question is why?
2013-09-22T20:22:15 < Laurenceb__> they were checking everyone in the building, i was about the only person
2013-09-22T20:22:29 < Laurenceb__> cuz it was on uni science park, and they had been hiring illegally
2013-09-22T20:22:32 < Laurenceb__> the uni
2013-09-22T20:22:56 < emeb_mac> didn't have the right paperwork on you or what?
2013-09-22T20:22:57 <+Steffanx> Laurenceb__ got trolled in rl?
2013-09-22T20:23:20 < Laurenceb__> yeah i had to prove i was entitled to be in the country

2013-09-22T20:24:02 < emeb_mac> so how did you convince them?
2013-09-22T20:24:09 < emeb_mac> "Here, call my mom."
2013-09-22T20:24:32 < Laurenceb__> found some bank papers and got them to ring my bank
2013-09-22T20:25:24 < emeb_mac> Oh what a world we live in.
2013-09-22T20:25:32 < emeb_mac> "Papers please"
2013-09-22T20:26:29 < emeb_mac> Time to start carrying a valid passport everywhere.
2013-09-22T20:26:45 <+Steffanx> Here in dutchland we are kind of forced to have one anyway.
2013-09-22T20:26:57 < emeb_mac> Oh?
2013-09-22T20:27:04 <+Steffanx> but im not sure if people like that are allowed to ask without a 'good' reason.
2013-09-22T20:27:11 < gxti> if that happened to me i'd show them my driver's license and if that wasn't good enough tell them to go fuck themselves
2013-09-22T20:27:50 < gxti> was annoying enough having to give a copy of my birth certificate when i was hired (also for employment eligivility reasons)
2013-09-22T20:27:56 < emeb_mac> gxti: yeah - I think a DL is considered sufficient proof of right to be in the country in the US
2013-09-22T20:28:43 < emeb_mac> which is why the feds want the states to beef up the security on the DL processing.
2013-09-22T20:28:44 < gxti> err, not birth cerificate, it was ss card
2013-09-22T20:29:02 < gxti> i ar bad at typing
2013-09-22T20:29:22 < emeb_mac> which is totally stupid as that's just a piece of paper with a name/number
2013-09-22T20:29:37 < gxti> a number i already gave them :p
2013-09-22T20:29:41 < emeb_mac> right
2013-09-22T20:29:58 <+Steffanx> We have fancy card like .. http://www.hulpdienstenonline.nl/files/images/NL%20ID%20kaart.jpg we are kind of forced to have it with us wherever we go :(
2013-09-22T20:30:09 <+Steffanx> RFID with fingerprints included ..
2013-09-22T20:30:11 < gxti> i think technically all US employers, no matter how small, are required to do that. but obviously some are less thorough about it than others.
2013-09-22T20:30:31 < emeb_mac> Steffanx: interesting.
2013-09-22T20:30:50 < emeb_mac> Every now and again someone here in the US tries to push something like that through
2013-09-22T20:31:08 < emeb_mac> gets all the right winger/libertarian folks riled up and it dies.
2013-09-22T20:31:53 < Laurenceb__>  < fairly libertarian
2013-09-22T20:31:59 < Laurenceb__> id never carry an id card
2013-09-22T20:32:15 <+Steffanx> Because of some recent change 'privacy blablabla' the finger prints aren't necessary anymore
2013-09-22T20:32:27 < emeb_mac> I got pulled over by a cop a while back for running a stop sign on my bike
2013-09-22T20:32:46 < emeb_mac> while writing the ticket he asked for my ID - I don't carry it while riding.
2013-09-22T20:32:55 < emeb_mac> No problem - just took my word for it.
2013-09-22T20:33:01 <+Steffanx> Laurenceb__, if the cops find a reason here to ask you for it and you cannot show it you'll get a fine ~50e or something.
2013-09-22T20:33:23 < Laurenceb__> eeek
2013-09-22T20:33:32 < Laurenceb__> i wont be coming to your country then
2013-09-22T20:33:51 <+Steffanx> They do need a reason to ask for it, but i bet they can kind of come up with whatever they want.
2013-09-22T20:33:56 < emeb_mac> Laurenceb__: but they have weeeed
2013-09-22T20:34:02 < gxti> emeb_mac: so do we
2013-09-22T20:34:14 < emeb_mac> gxti: you in CO / WA?
2013-09-22T20:34:16 <+Steffanx> Like you don't have that in the UK

2013-09-22T20:34:35 < emeb_mac> har. Nice delusion there.
2013-09-22T20:35:12 < gxti> well from a practical standpoint now that two states have semi-legalized it, it's going to accelerate the cause faster
2013-09-22T20:35:22 < gxti> although i don't really care that much about weed
2013-09-22T20:35:42 <+Steffanx> No no.. you are a weed head now. Just like me
2013-09-22T20:35:46 < emeb_mac> not a big part of my life. but happy to see law enforcement focus on real problems.
2013-09-22T20:35:53 < gxti> yeah that's the main thing
2013-09-22T20:36:14 <+Steffanx> The problem is emeb_mac.. who decides if something is a real problem?

2013-09-22T21:25:37 < gxti> front panel express is too expensive... looks like my only options are going to hammond for customizations (don't know the cost or minimums), or using acrylic from ponoko or similar :(
2013-09-22T21:26:34 < emeb_mac> FPE isn't cheap
2013-09-22T21:26:42 < emeb_mac> Cheaper if you don't get lettering tho
2013-09-22T21:26:53 < gxti> i haven't even put the lettering on yet, just the holes.
2013-09-22T21:27:12 < emeb_mac> don't know if they still charge by the stroke
2013-09-22T21:27:30 < emeb_mac> there used to be optimizers out there that would remove redundant strokes and reduce the cost.
2013-09-22T21:27:47 < gxti> the best i can get it is $14.66 and that's with no countersink and with large radii on the cutouts
2013-09-22T21:27:48 < Laurenceb__> cant you just print the panel?
2013-09-22T21:27:49 < gxti> and that's one end
2013-09-22T21:28:08 < gxti> with no letters.
2013-09-22T21:28:24 < Laurenceb__> wtf

2013-09-22T21:28:34 < Laurenceb__> $162...
2013-09-22T21:28:40 < Laurenceb__> id pay like $6
2013-09-22T21:28:50 < emeb_mac> where would you pay that?

2013-09-22T21:29:30 < emeb_mac> but lovely D-sub punchouts!
2013-09-22T21:29:42 < Laurenceb__> use a file
2013-09-22T21:29:55 < emeb_mac> and how many hours of your life would that take?
2013-09-22T21:30:08 < gxti> more than $6 worth, no question
2013-09-22T21:30:12 < Laurenceb__> 15minutes or so
2013-09-22T21:30:18 < gxti> rofl, no
2013-09-22T21:30:24 < Laurenceb__> or if you want to be fancy, a slot cutter
2013-09-22T21:30:42 < qyx_> $15 for just one end?
2013-09-22T21:30:54 < qyx_> cutouts only?
2013-09-22T21:31:03 < Laurenceb__> the prices are mad
2013-09-22T21:31:05 < gxti> yep. bare minimum. no tool changes.
2013-09-22T21:31:14 < gxti> 2/3 is "preparing/finishing" charge
2013-09-22T21:31:33 < qyx_> mine were considerably cheaper
2013-09-22T21:33:11 < Laurenceb__> if you are going to spend that much, get some proper membrane button materials from 3M

2013-09-22T21:37:50 < gxti> anyway, i remember someone on irc had used hammond before but i don't remember who... might have to get a quote

2013-09-23T02:51:48 < gxti> arduino retina
2013-09-23T02:52:26 < gxti> so here's the idea i had for linker script for a bootloaded app: https://github.com/mtharp/laureline-firmware/commit/a50c3313c0ff583b6f6243d2cad9181b185cdd0d
2013-09-23T02:52:41 < dongs> attn Laurenceb http://islamqa.com/en/ref/103871
2013-09-23T02:52:54 < gxti> everything starts at 2K (flash page #2), with a little stub at zero so you can load it without the bootloader
2013-09-23T02:53:31 < dongs> what does bootloader stub do?
2013-09-23T02:53:33 < dongs> jumps to 2k?
2013-09-23T02:53:36 < zyp> gxti, fun, but does it really have an advantage over just flashing the bootloader once?
2013-09-23T02:54:09 < gxti> dongs: sort of, it just has a mini vector table pointing to the same reset handler
2013-09-23T02:54:39 < dongs> whats the difference tho
2013-09-23T02:54:46 < dongs> are you implementing "bootloader" in your app? or what
2013-09-23T02:55:01 < dongs> isnt whole point of separating bootloaer + app is so you can erase flash knowing where shit is
2013-09-23T02:55:14 < dongs> how you gonna guarantee your bl code isn't gonna get erased by itself
2013-09-23T02:55:17 < dongs> in your situation
2013-09-23T02:55:20 < gxti> right, the stub isn't a bootloader it's a dummy for when you're debugging
2013-09-23T02:55:31 < gxti> the bootloader itself occupies first 2k + end of flash
2013-09-23T02:55:31 < zyp> I just wrote a bootloader for my own stuff
2013-09-23T02:55:36 < dongs> i have no problem debugging bootloaded stuff ?_?
2013-09-23T02:55:44 < zyp> managed to get DFU mode working a few hours ago
2013-09-23T02:55:48 < dongs> even if it starts at 80003000 or whatever
2013-09-23T02:55:53 < zyp> also, debugging bootloaded stuff is no problem
2013-09-23T02:55:57 < dongs> yeah..
2013-09-23T02:56:09 < dongs> no change in keil at least, I'm sure you need another mile of command lines for gdb
2013-09-23T02:56:11 < zyp> I can flash from gdb, and it will just skip over the bootloader and leave it alone
2013-09-23T02:56:13 < gxti> normally it's not, i've had issues before though because my bootloader is networked and has to read eeproma nd shit
2013-09-23T02:56:51 < zyp> my bootloader does as little as possible before deciding whether to bootload or boot normally
2013-09-23T02:57:00 < gxti> and yes for the most part gdb can step over it, it's just one little thing i'd rather not dick with. not saying this is a crowning accomplishment or anything, just kinda nifty
2013-09-23T02:57:25 < zyp> sure, except the fact that you will now always overwrite the bootloader .p
2013-09-23T02:57:28 < zyp> :p
2013-09-23T02:58:56 < gxti> that's been less of an issue than the opposite so far, but it's still trivial to strip out the stub section
2013-09-23T02:59:35 < gxti> anyway time to port the actual bootloader
2013-09-23T02:59:57 < gxti> i like this fixed 2k page offset much more than having to reserve the entire 24k space, and then being stuck with that offset forever
2013-09-23T03:00:15 < zyp> offset?
2013-09-23T03:00:40 < gxti> rom where the actual application begins
2013-09-23T03:01:03 < gxti> bootloader only takes up the first page, plus however much it needs from the end
2013-09-23T03:01:10 < zyp> http://paste.jvnv.net/view/f8U6I <- here's the stuff I just wrote
2013-09-23T03:01:27 < zyp> oh, that's neat
2013-09-23T03:01:59 < gxti> then it can get as fat or thin as i want without having to recompile the app (and breaking compatibility with existing released bins)
2013-09-23T03:02:24 < zyp> can you get the linker to calculate where to place it at the end automatically, or do you have to adjust it?
2013-09-23T03:03:13 < gxti> hmm, that part might suck. although i can automate it by doing a test link and rewriting the script with the actual size.
2013-09-23T03:04:10 < zyp> also means that the bootloader have to be tailored for each flash size, if you want to be able to use all the flash in the future
2013-09-23T03:04:44 < gxti> yeah but that seems like a fine tradeoff
2013-09-23T03:05:46 < zyp> at least if you expect to fuck around more with the bootloader later
2013-09-23T03:06:03 < zyp> I don't
2013-09-23T03:06:35 < zyp> well, I reserved 8k for mine, currently using 5k or so
2013-09-23T03:06:36 < gxti> *i* might, but the important part is someone who needs the bootloader to begin with won't and can't
2013-09-23T03:08:07 < zyp> it's not like I can't afford to reserve 8k for the bootloader, even though it would strictly fit in 6k :p
2013-09-23T03:08:29 < zyp> the main application is still less than 8k, and I have a full 128k or 256k to spend :p
2013-09-23T03:08:51 < gxti> it gets worse when you need ethernet though, because the 24k i reserved is fine but limits future features and makes it hard to debug because if i take off -Os it doesn't fit anymore
2013-09-23T03:09:04 < gxti> it will probably shrink from that once i stop chatting and start ditching chibios
2013-09-23T03:09:19 < zyp> fair enough
2013-09-23T03:10:01 < zyp> how much flash do you have?
2013-09-23T03:10:04 < gxti> i also have a FAT version but haven't decided whether to commit to having a sd slot on the hardware
2013-09-23T03:10:13 < gxti> 128k, using less than half for the app right now
2013-09-23T03:11:00 < zyp> hmm, there are that small chips with ethernet? F107xB?
2013-09-23T03:12:14 < gxti> yeah, actually 107rc which is 256k, but i started with 107rb
2013-09-23T03:12:40 < gxti> got 30 count 107rc from verical for half the price of digikey, a nice upgrade
2013-09-23T03:12:41 < zyp> wait, r? there are 64-pin chips with ethernet?!
2013-09-23T03:13:10 < zyp> hmm, RMII is not that many pins after all
2013-09-23T03:13:19 < qyx_> even mii
2013-09-23T03:14:17 < gxti> mii on this part would be ridiculous, it craps on enough peripherals' pins already
2013-09-23T03:14:31 < zyp> :p
2013-09-23T03:14:45 < qyx_> i should move to rmii
2013-09-23T03:15:00 < gxti> rmii PHYs are also the cheapest, which is all the motivation i need
2013-09-23T03:15:11 < qyx_> but i don't like the idea of using mlf package for phy
2013-09-23T03:15:25 < qyx_> or qfn or whatever is that
2013-09-23T03:15:31 < gxti> so far it's given me remarkably little trouble
2013-09-23T03:16:18 < zyp> which ones are you using?
2013-09-23T03:16:25 < zyp> I tend to see dp83848 everywhere
2013-09-23T03:16:39 < gxti> ksz8031RNL
2013-09-23T03:16:40 < qyx_> currently ksz8051mll
2013-09-23T03:16:48 < qyx_> but considering the one gxti uses
2013-09-23T03:17:19 < gxti> they're all the same to me, i buy whatever's cheapest as long as it's unlikely to get obsoleted with no replacement

2013-09-23T03:36:59 < zyp> hmm, hsync and vsync
2013-09-23T03:37:10 < zyp> wonder if it could do vga
2013-09-23T03:37:11 < gxti> i'm not even sure if i want to keep using the network bootloader. SD might be smarter, because i also have another unsolved problem: the only way to configure a static IP is through a logic-level uart debug header. so SD offers an option to solve that by putting a config file on it.
2013-09-23T03:37:13 < dongs> does it have separate memory for framebuffer?
2013-09-23T03:37:56 < Thorn> that would be at least 1.5Meg
2013-09-23T03:38:10 < zyp> there is another 64k memory block in the chip
2013-09-23T03:38:25 < dongs> whats the fucking point of having 800x600 LCD controller if you cant doublebuffer it?
2013-09-23T03:38:25 < zyp> after the 112k+16k that the old F4 has
2013-09-23T03:38:36 < Thorn> I guess that's what SDRAM is for
2013-09-23T03:38:39 < zyp> but then there's the sdram controller
2013-09-23T03:38:39 < dongs> heh
2013-09-23T03:38:56 < zyp> f429-discovery comes with 8MB SDRAM
2013-09-23T03:39:02 < dongs> cool
2013-09-23T03:39:07 < dongs> just SDR?
2013-09-23T03:39:11 < dongs> not DDR/DDR2/3?
2013-09-23T03:39:17 < zyp> probably
2013-09-23T03:39:23 < Thorn> they don't say anything about double buffering but maybe you can reprogram the buffer address register after each frame
2013-09-23T03:39:24 < zyp> hmm, I'll check

2013-09-23T03:44:53 < Thorn> it's in fig. 2
2013-09-23T03:44:58 < Thorn> right
2013-09-23T03:47:04 < zyp> hmm, looks like the lcd controller is flexible enough to do vga
2013-09-23T03:47:22 < zyp> just need some sort of DAC on the signals
2013-09-23T03:47:39 < Thorn> so the question is, if you have a 800x600 framebuffer in sdram, how much bus time (both fmc and the internal) remains to draw pretty pictures in the framebuffer
2013-09-23T03:47:56 < zyp> it says it does 16 word bursts
2013-09-23T03:48:15 < zyp> which should do nicely with sdrams since sdrams are usually also read in bursts
2013-09-23T03:49:14 < qyx_> hm, supports color tables
2013-09-23T03:50:34 < Thorn> do I understand the bus matrix correctly? e.g. can instruction fetch from flash and dma to ram happen at the same time without arbitration?
2013-09-23T03:50:41 < zyp> if you're gonna do 16bpp 30fps, you're looking at a data rate of 28.8 Mb/s
2013-09-23T03:50:45 < zyp> Thorn, of course
2013-09-23T03:50:51 < Thorn> nice
2013-09-23T03:51:56 < zyp> hmm, 7.2 MHz if you have a 32-bit wide SDRAM
2013-09-23T03:52:10 < Thorn> what package will you need
2013-09-23T03:52:20 < zyp> if it can run the memory at 100 MHz or so, you'll probably have plenty
2013-09-23T03:52:28 < Thorn> a crapload of pins for the lcd and another crapload for sdram
2013-09-23T03:52:44 < zyp> lcd is 28 pins at most
2013-09-23T03:53:03 < Thorn> hopefully they don't overlap
2013-09-23T03:53:03 < zyp> sdram is 50 or so
2013-09-23T03:53:48 < zyp> even with a 16-bit wide sdram, you'll probably have plenty
2013-09-23T03:55:52 < Thorn> well, the discovery has both lcd and sdram (probably not 32 bit wide though) and a 144 pin package
2013-09-23T03:56:58 < zyp> the one on the discovery board is 16-bit wide
2013-09-23T03:57:26 < Thorn> yes, dq0...dq15

2013-09-23T03:59:00 < zyp> rule of thumb is one per power pins, and it has ~13 power pins
2013-09-23T04:01:45 < zyp> oh
2013-09-23T04:02:02 < Thorn> The STM32F429ZIT6 MCU reads and writes data at 80 MHz.
2013-09-23T04:02:19 < zyp> ST apparently have some addon board planned
2013-09-23T04:02:19 < Thorn> (sdram)
2013-09-23T04:02:49 < zyp> the weird connector-thing in the upper right corner is an angled female header with i2c and one gpio
2013-09-23T04:03:08 < zyp> it's labeled «ACP/RF E2P Connector»
2013-09-23T04:03:21 < zyp> the gpio is named «ACP_RST»
2013-09-23T04:03:22 < Thorn> I wonder if rmii pins are still available in that package
2013-09-23T04:03:29 < zyp> any idea what this can be?
2013-09-23T04:03:42 < dongs> maybe its for NFC
2013-09-23T04:04:09 < zyp> yeah, except ST NFC chips doesn't do I2C
2013-09-23T04:06:06 < zyp> the lcd they put on it is 18bpp
2013-09-23T04:06:10 < zyp> i.e. RGB666
2013-09-23T04:07:37 < zyp> and is hooked up to some I2C touchscreen controller
2013-09-23T04:13:06 < Thorn> it supports AC97?
2013-09-23T04:13:42 < Thorn> Peripheral with large configurability and flexibility allowing to target as example the following audio protocol: I2S, LSB or MSB-justified, PCM/DSP, TDM, AC’97
2013-09-23T04:14:08 < zyp> sure

2013-09-23T04:14:50 < dongs> what hte fuck is this
2013-09-23T04:17:35 < zyp> looks like bullshit
2013-09-23T04:21:32 < dongs> aparently its on this 28" 3840x2160 panel
2013-09-23T04:30:07 < Thorn> why do they call dynamic ram "ram"
2013-09-23T04:30:15 < Thorn> it's hardly random access
2013-09-23T04:31:40 < dongs> random rape
2013-09-23T04:40:01 < Thorn> SDRAM clock can be HCLK/2 or HCLK/3

2013-09-23T04:41:30 < R2COM> bought bunch of pressure sensors for altimeter related stuff
2013-09-23T04:41:40 < R2COM> but ordered gage ones... that was stupid.
2013-09-23T04:42:29 < talsit> which did you get?
2013-09-23T04:42:43 < R2COM> by the way, I notice that this stuff costs around 40$ in general, something what measures 0-15PSI, and has digital output with SPI
2013-09-23T04:43:05 < R2COM> I will order another honeywell sensor
2013-09-23T04:43:16 < R2COM> but those are 45$ or so
2013-09-23T04:43:36 < R2COM> I mean its ok, but I was just curious if there are ones for a cheap price
2013-09-23T04:45:52 < Fornaxian> not so accurate but usable for some things,,,pvc bits-n-pieces, piece of rubber, and a linear slide pot along with some connecting bits to tie the pot to the rubber.
2013-09-23T04:46:45 < Fornaxian> pressurize tube with rubber stretched over the end and the linear pot connected to it with a pivot that can be moved for sensitivity adjustment.
2013-09-23T04:47:34 < R2COM> what the fuck was that
2013-09-23T04:48:18 < Fornaxian> I made one with a switch instead of a linear pot to control water pressure on a portable camping rig.
2013-09-23T04:48:46 < R2COM> why the fuck would i loose time on that, i order professionally made part and use it
2013-09-23T04:49:00 < Fornaxian> that works too.

2013-09-23T04:52:47 < R2COM> cuz theres single and burst reads/writes depending on whats required
2013-09-23T04:52:53 < R2COM> as far as I remember...
2013-09-23T04:54:53 < Thorn> the bus supports that?
2013-09-23T04:55:13 < Thorn> "The DMA attempts to execute fixed-length burst transfers on the AHB master interface"
2013-09-23T04:55:57 < Thorn> interesting
2013-09-23T04:56:21 < Thorn> When the AHB Interface is configured for fixed-length burst, then it transfers data using the best combination of INCR4, INCR8, INCR16 and SINGLE transactions.
2013-09-23T05:00:53 < dongs> they should make a PHB bus

2013-09-23T09:20:08 < ds2> isn't a perl script easier?
2013-09-23T09:20:42 < R2COM> why perl I dont need it here
2013-09-23T09:21:07 < R2COM> I'm using matlab, and I wish they provided a nice routines for handling these kinds of things
2013-09-23T09:21:24 < R2COM> becuase from time to time its more handy to manipulate it with binary files for some data etc right there
2013-09-23T09:21:31 < R2COM> rather than loading another c program for it
2013-09-23T09:28:32 < emeb_mac> I suppose you could write a MEX file for it, but that's hardly better than coding C externally.

2013-09-23T09:44:28 < R2COM> i.e. it shows 0 PSI now, because no pressure is applied
2013-09-23T09:44:39 < dongs> right, so its differential
2013-09-23T09:44:47 < R2COM> no its not fucking differential
2013-09-23T09:44:48 < dongs> zero when nothing, and if you suck in/out it'll change
2013-09-23T09:44:51 < R2COM> differential is differential

2013-09-23T09:45:13 < dongs> how does it know "now" is zero

2013-09-23T09:45:18 < dongs> does it calibrate at power up/
2013-09-23T09:45:23 < dongs> to 'current' pressure>
2013-09-23T09:45:56 < R2COM> it depends on architecture, most just have another measurement input for current pressure

2013-09-23T12:13:02 < karlp> thanks ST.
2013-09-23T12:15:23 < karlp> jon1012: f4 is contiguous though, so shouldn't matter there.

2013-09-23T12:54:57 < karlp> yeah, rereading the l1 ref manual (I'd originally written this for the f100) and it's offsets 0, 4 and 0x14, instead of 0, 4, 8 like the f0,f1,f3,f4 :|
2013-09-23T12:55:18 < karlp> andnow they seem to be unique again...

2013-09-23T13:09:27 < dongs> no, must be something else
2013-09-23T13:15:16 < karlp> the 3x32bit unique id registers are contiguous on f0,f1,f2,f3,f4 (offsets 0,4,8) but are broken on L1 (0,4,0x14)
2013-09-23T13:15:33 < Robint91> karlp, who f*cked that up
2013-09-23T13:16:00 < karlp> well, I fucked up reading the ref manual, and just updated the base address,
2013-09-23T13:16:12 < karlp> but st fucked up putting them like that :|
2013-09-23T13:16:20 < Robint91> :)
2013-09-23T13:16:23 < dongs> oh
2013-09-23T13:16:27 < dongs> what the hell
2013-09-23T13:16:48 < dongs> i wonder why would they do that
2013-09-23T13:16:55 < dongs> whats between 0x4 and 0x14 on L?
2013-09-23T13:17:00 < dongs> some other crap? or just empty
2013-09-23T13:17:27 < karlp> well, all of them had the same at offset 8, which is how this came up, my "unique id" wasn't unique
2013-09-23T13:17:45 < karlp> haven't looked at the rest, but I can if you like, and I suppose I might as well dump it all
2013-09-23T13:22:05 < karlp> looks like the other stuff is "other crap" that is always the same
2013-09-23T13:24:41 < trepidaciousMBR_> The actual unique id's also seem to share a lot of bits between different devices
2013-09-23T13:24:50 < trepidaciousMBR_> although hopefully not all of them :)
2013-09-23T13:25:17 < Robint91> trepidaciousMBR_, they include things like fab num, lot num, wafer num, wafer loc
2013-09-23T13:25:39 < Robint91> trepidaciousMBR_, to get a more randon numer
2013-09-23T13:25:51 < karlp> http://paste.fedoraproject.org/41485/79931939/
2013-09-23T13:26:26 < trepidaciousMBR_> I wanted to generate "local" MAC addresses from the device id, and I needed to be pretty careful to use all the bits as a seed to generate a pseudo random number, my first attempt generated the same MAC for the first two devices I tried :)
2013-09-23T13:26:46 < karlp> yeah, you have to use _all_ of it.

2013-09-23T15:28:45 < talsit> hey, strange question, with a STM32F051, I have an xtal of 26MHz, and I had set the PREDIV to 4, and PLLMUL to 7, to get 45.5MHz, why would that give me any issues?
2013-09-23T15:28:54 < talsit> does the final clock have to be a whole number?
2013-09-23T15:29:21 < talsit> (i have now changed it to PREDIV of 13 and PLLMUL of 16 to get 32MHz, which is good enough
2013-09-23T15:29:21 < zyp> not unless your peripherals require it
2013-09-23T15:29:28 < gxti> no. i also have a 26mhz oscillator.
2013-09-23T15:29:41 < gxti> which i'm using at 69.333333MHz.
2013-09-23T15:29:45 < talsit> well, it was running fine for about 5-6 seconds, then it would fuck up
2013-09-23T15:29:49 < zyp> are you sure F051 is rated to work with that fast clocks?
2013-09-23T15:29:51 < Thorn> I have a "thermocouple for a multimeter" (that's all I know about it). It generates 7.5mV when heated with a 280°C soldering iron. does this look like type K? the tables show 11.3mV
2013-09-23T15:30:04 < talsit> the 051 is up to 32MHz xtal
2013-09-23T15:30:18 < Thorn> do all DMMs use type K?
2013-09-23T15:30:25 < talsit> according to datasheet
2013-09-23T15:30:28 < Robint91> Thorn, compensated your cold junction?
2013-09-23T15:30:38 < gxti> Thorn: it is probable but not guaranteed
2013-09-23T15:30:48 < talsit> 4-32MHz crystal oscillator
2013-09-23T15:31:31 < Thorn> cold junction is at ~25°C, so 10.3mV
2013-09-23T15:31:40 < Thorn> still not 7.5
2013-09-23T15:32:51 < Thorn> can this be because of the input resistance of the DMM?
2013-09-23T15:33:14 < Robint91> Thorn, does you multimeter have a temp range?
2013-09-23T15:33:38 < Thorn> no it doesn't
2013-09-23T15:34:59 < zyp> talsit, have you configured the wait states in the flash interface correctly for the speed you're running?
2013-09-23T15:35:27 < talsit> zyp: probably not
2013-09-23T15:35:39 < zyp> then there's your issue
2013-09-23T15:36:03 < zyp> if you try reading the flash too fast, it'll fuck up and then you get invalid instructions
2013-09-23T15:37:56 < talsit> now to find if i'm doing that or not

2013-09-23T15:51:04 < Laurenceb> no
2013-09-23T15:51:09 < Laurenceb> its secret
2013-09-23T15:51:45 <+Steffanx> Did you sign an NDA?
2013-09-23T15:55:59 < PaulFertser> TikZ actually provides decent and maintainable results, unlike msword's "vector graphics".
2013-09-23T15:56:42 < Laurenceb> maybe i could use inkscape
2013-09-23T15:58:54 < Laurenceb> ah yeah this works :P

2013-09-23T17:28:58 < zyp> you know what a literal is?
2013-09-23T17:29:52 < zyp> in this context, a literal is a piece of data that is stored in the flash, along with the code
2013-09-23T17:29:57 < Thorn> part of an instruction containing a value?
2013-09-23T17:30:26 < zyp> the compiler usually emits a literal pool after each function containing data that the function will load
2013-09-23T17:30:32 < Thorn> oh it is connected to the DCODE bus. but why also SRAM1
2013-09-23T17:31:47 < zyp> http://paste.jvnv.net/view/QXXFV <- consider this, the last three lines there is a literal pool

2013-09-23T17:34:27 < zyp> hmm
2013-09-23T17:34:45 < Thorn> so why not say "data load from flash". to me, a literal is that value 88 for example (which is fetched through the I-bus with the rest of the instruction)
2013-09-23T17:35:33 < zyp> dongs, this 100-board batch, how long does stuff like that take? when can I expect to have them here?

2013-09-23T18:20:33 < trepidaciousMBR_> It just recognises a coil screwed onto the pen, you could presumably attach the coil to anything
2013-09-23T18:21:13 < trepidaciousMBR_> IMHO it's still not that much use, I've used similar systems and it's just a pain. What you need is a decent digitiser in the screen, like a Surface or one of the Samsung tablets

2013-09-24T01:20:03 < talsit> anyone used stm32flash on windows?
2013-09-24T01:21:32 < talsit> just trying to read info on the device gives me a "COM16: no error"
2013-09-24T01:21:49 < 17SADE90V> Thorn: I'm not sure how to use the pieces of code you showed me.  Any more concrete example?
2013-09-24T01:22:04 < Thorn> talsit: \\.\COM16 or something?
2013-09-24T01:22:18 < talsit> really?
2013-09-24T01:22:21 < talsit> ok, lets try
2013-09-24T01:22:28 < Thorn> (no idea about stm32flash itself)
2013-09-24T01:22:39 < talsit> yep, that's getting me somewhere
2013-09-24T01:24:11 < 17SADE90V> Thorn: where do I put all the 4 lines you wrote? In my main.c file?
2013-09-24T01:24:12 < Thorn> 17SADE90V: the first two lines you add to your linker script (if you're using some example skeleton they may already be there), the 3rd one is how you put a variable into a specififc section (in this case, CCM)
2013-09-24T01:25:54 < talsit> i dunno if my stm32flash supports my f051
2013-09-24T01:27:32 < 17SADE90V> Thorn: If I define "a_variable" of type int in CCM, do I do it like this?  int a __attribute__((section(".ccm"))) a_variable;
2013-09-24T01:28:07 < Thorn> int a a_variable; is not correct C
2013-09-24T01:28:23 < Thorn> remove the a
2013-09-24T01:29:03 < Thorn> also the __attribute__ may need to be at the end of the statement, not sure
2013-09-24T01:29:46 < 17SADE90V> Then: int my_variable a __attribute__((section(".ccm")));
2013-09-24T01:29:52 < 17SADE90V> Would that be correct?
2013-09-24T01:30:10 < Thorn> remove the a
2013-09-24T01:30:54 < 17SADE90V> I see. I guess a is your variable already
2013-09-24T01:32:10 < 17SADE90V> Thorn: What does the define line do?
2013-09-24T01:33:04 < gxti> try thinking about it for a minute or two
2013-09-24T01:33:32 < Thorn> defines a macro
2013-09-24T01:34:26 < Thorn> which you can use instead of __attribute__(((((((((()))))))))
2013-09-24T01:34:47 < 17SADE90V> Haha
2013-09-24T01:34:54 < 17SADE90V> Thanks Thorn
2013-09-24T01:41:19 < dongs> Thorn: thats olimexi trash.
2013-09-24T01:41:46 < dongs> that was their mistake to pick such a dumb lcd.
2013-09-24T01:42:16 < Thorn> it seems to be widely available
2013-09-24T01:42:55 < dongs> sure, but thats a LOT of extra support garbage.
2013-09-24T01:43:11 < dongs> plus how much is a cheap 800x480 lcd really anyway. like 20 bucks tops?
2013-09-24T01:43:25 < Thorn> having 3 voltages isn't as horrible as the need to sequence them (and I don't recall any sequencing in their schematics)
2013-09-24T01:43:25 < dongs> pick one that doesnt need idiotic sequencing
2013-09-24T01:43:26 < dongs> done.
2013-09-24T01:43:53 < dongs> k today is assemble stuff day
2013-09-24T01:43:56 < dongs> instead of argue about stuff day.
2013-09-24T01:43:57 < Thorn> I found a factory ("We're a factory since 2003!") http://www.buy-display.com/
2013-09-24T01:44:09 < Thorn> they sell on aliexpress

2013-09-24T05:23:05 < dongs> those wires.
2013-09-24T05:23:25 < R2COM> thats an LDO chip, just needs input, output, reference and bias wires.
2013-09-24T05:23:27 < R2COM> well and ground.
2013-09-24T05:23:33 < dongs> wtf
2013-09-24T05:23:38 < dongs> why teh fuck are you making LDO asic

2013-09-24T05:24:24 < R2COM> it is just to test-drive the technology. and check some specific ldo architecture
2013-09-24T05:25:27 < R2COM> any big SoC or other type of complex chip has some ldo, usually people design and test those separately before integrating into the system. but in this case it was just quick test.

2013-09-24T05:42:41 < dongs> i soldered F103's on the board that needed 303.
2013-09-24T05:46:14 < dongs> 303 flash algorithm works on 103 tho.
2013-09-24T05:49:16 < R2COM> so my honeywell sensors temp. output works pretty nicely too
2013-09-24T05:52:36 < dongs> hmm
2013-09-24T05:52:41 < dongs> this MAX switch is way better quality
2013-09-24T05:52:46 < dongs> than ADG804
2013-09-24T05:52:52 < dongs> the break before make time is shorter

2013-09-24T06:11:46 < R2COM1> what else
2013-09-24T06:11:52 < dongs> generally the point of it is that you don't clean it off pcb
2013-09-24T06:12:07 < talsit> you want to remove conformal from PCB?
2013-09-24T06:12:13 < R2COM1> how easy is it to lets say do some rework on some pins/small component when its on?
2013-09-24T06:12:17 < talsit> if it's acrylic, then pretty easy
2013-09-24T06:12:37 < talsit> acrylic and silicone conformal is usually workable, as in, you can solder through it
2013-09-24T06:12:53 < talsit> polyurethene, i believe you need a solvent first
2013-09-24T06:12:58 < talsit> and epoxy is permanent

2013-09-24T07:48:08 < R2COM> which functions for square root is commonly used
2013-09-24T07:48:09 < R2COM> arm_sqrt_f32 ?
2013-09-24T07:50:19 < dongs> well m4 has hardware sqrt instruction
2013-09-24T07:50:34 < dongs> i guess if youre using the dsp lib it'll probly #ifdef based on arch
2013-09-24T07:51:58 < R2COM> I dont use it
2013-09-24T07:52:05 < R2COM> I just added arm_corecm4
2013-09-24T07:52:08 < dongs>  < R2COM> arm_sqrt_f32 ?
2013-09-24T07:52:11 < dongs> thats dsplib
2013-09-24T07:52:20 < R2COM> its in arm_math.h
2013-09-24T07:52:29 < dongs> hokay. well then use it
2013-09-24T07:54:08 < R2COM> ok it worked
2013-09-24T07:54:13 < R2COM> I am retarded
2013-09-24T07:54:30 < R2COM> I did y = arm_sqrt_f32(x, &y);   and then wonder why y=0
2013-09-24T07:57:05 < dongs> gg
2013-09-24T07:59:52 < R2COM> ok, the rest of the work goes tomorrow
2013-09-24T08:00:24 < R2COM> now shower, and just relaxed readon about radar processing, then sleep
2013-09-24T08:07:38 < R2COM> that green connector for power I showed above on one of my boards is shitty
2013-09-24T08:07:52 < R2COM> over the time it gets loose, no matter how firm the soldering is
2013-09-24T08:08:06 < R2COM> in fact...the bad thing about it is, it does not depend much on soldering quality
2013-09-24T08:08:19 < R2COM> even if solder is firmly attaching pins, it gets loose around the pins
2013-09-24T08:08:22 < R2COM> so fuck that shit.
2013-09-24T08:08:25 < R2COM> not gona use anymore
2013-09-24T08:09:31 < R2COM> anyhow.
2013-09-24T08:09:47 < R2COM> also, someone before showed here that grey cables with matching connectors for BMP probe
2013-09-24T08:09:56 < R2COM> anyone knows link to it?
2013-09-24T08:10:06 < R2COM> I want to buy cable which comes in a package when you get BMP probe

2013-09-24T08:36:19 < emeb_mac> dongs linked me that a while back - got some, they work fine with my BMP and BMP2
2013-09-24T08:36:24 < dongs> ah yes
2013-09-24T08:36:28 < dongs> i still have a few left in a bag
2013-09-24T08:36:33 < dongs> will buy more next time im in america
2013-09-24T08:36:38 < dongs> those are good
2013-09-24T08:36:44 < emeb_mac> and CHEEP
2013-09-24T08:36:51 < dongs> right
2013-09-24T08:36:54 < R2COM> you only buy it if you in america?
2013-09-24T08:36:55 < dongs> same shit @ digieky is 12bucks each
2013-09-24T08:37:11 < dongs> well im sure they'll ship to soviet russia for a price
2013-09-24T08:37:34 < emeb_mac> postage probably makes DK look like a good deal
2013-09-24T08:37:49 < dongs> heh, their usps to alaska was cheap

2013-09-24T10:14:20 < emeb_mac> stop shouting please, I'm trying to sleep
2013-09-24T10:14:46 < R2COM> so
2013-09-24T10:15:00 < R2COM> very low power uC's with analog blocks nowadays considered PsOC?
2013-09-24T10:15:24 < emeb_mac> as long as they're from Cypress
2013-09-24T10:15:58 < R2COM> sure from whom else they could be
2013-09-24T10:17:07 < emeb_mac> doesn't Lattice have something like that?
2013-09-24T10:17:23 < emeb_mac> maybe not low power and maybe FPGA instead of uC
2013-09-24T10:18:10 < R2COM> so
2013-09-24T10:18:15 < R2COM> im looking at datasheet of psoc3
2013-09-24T10:18:20 < R2COM> it has opamp
2013-09-24T10:18:22 < R2COM> comparator
2013-09-24T10:18:28 < R2COM> pgas
2013-09-24T10:18:29 < R2COM> dac
2013-09-24T10:18:30 < R2COM> adc
2013-09-24T10:18:37 < dongs> dongs
2013-09-24T10:18:39 < R2COM> and even a mixer capable to 1MHz frequencies
2013-09-24T10:19:09 < R2COM> was curious for a second...so technically one can build a low freq. radio transmitter on it then
2013-09-24T10:19:10 < R2COM> or
2013-09-24T10:19:11 < R2COM> hmm
2013-09-24T10:19:41 < R2COM> soo look like that
2013-09-24T10:19:56 < jpa-> one can build low-freq transmitter on pretty much anything
2013-09-24T10:20:07 < R2COM> well
2013-09-24T10:20:09 < jpa-> but what use is it? you still need a huge antenna for such freqs
2013-09-24T10:20:12 < R2COM> this thing is also very low power
2013-09-24T10:20:23 < R2COM> its sleep is 1uA
2013-09-24T10:20:48 < R2COM> huge antenna yes. but... but but :)
2013-09-24T10:21:25 < R2COM> anyhow.
2013-09-24T10:21:42 < R2COM> advantage of this would be the ability (I guess for now..) to freely interconnect all those blocks
2013-09-24T10:21:52 < jpa-> sounds about the same sleep current as CC430
2013-09-24T10:21:52 < R2COM> in case if for example I need to sense something, and then transmit it
2013-09-24T10:22:04 < R2COM> you can arrange there amplifiers in a way you want
2013-09-24T10:22:14 < R2COM> before feeding to adc I assume
2013-09-24T10:22:31 < R2COM> so... I dont think you can do that on "anything"
2013-09-24T10:22:50 < R2COM> by "anything" I mean something what would let you do it within a single chip
2013-09-24T10:23:16 < jpa-> yeah; it all just depends if anyone even wants to do it in the first place :)

2013-09-24T12:18:09 < jpa-> you have to add some crazy switches and openocd will do it
2013-09-24T12:18:15 < Thorn> (and texane stlink which seems quite buggy)

2013-09-24T12:19:14 < ouah> jpa-: texane stlink is also openocd?

2013-09-24T12:28:42 < karlp> texane stlink can be used as a gdbserver or as just a command line flash tool too
2013-09-24T12:30:00 < zyp> true
2013-09-24T12:30:09 < ouah> ok will take a look at both, thanks

2013-09-24T12:32:39 < ouah> I don't to want to avoid it but I would prefer a standalone tool because I'm looking for a small, simple and fast tool ;)
2013-09-24T12:34:33 < zyp> well, the smallest and simplest would be the st-flash utility included with texane st-link
2013-09-24T12:34:41 < zyp> the question is just whether it works properly :p

2013-09-24T12:40:21 < jpa-> it works properly most of the time :)
2013-09-24T12:40:38 < ouah> ok, so this is a no-go for texane st-link ;)
2013-09-24T12:40:44 < ouah> for me at least
2013-09-24T12:40:47 < jpa-> but you can use openocd from command line just fine also, the problem is only that you need to figure out the bunch of switches you need to give to it
2013-09-24T12:41:02 < jpa-> ouah: why? openocd doesn't work properly 100% of time either
2013-09-24T12:41:31 < ouah> ... that smells not good
2013-09-24T12:41:38 < jpa-> for example, if your cpu goes to sleep too early, you need to give a separate set of crazy switches to bring it back; and yet another if you are using WFI
2013-09-24T12:42:33 < jpa-> but it works most of the time, just like everything else in this world
2013-09-24T12:44:06 < karlp> the libopencm3-examples makefiles hve the command line switches for programming via openocd
2013-09-24T12:44:45 < karlp> jpa-: just saw an errata on the L series about modifying your wfe calls to have an extra nop int hem if you don't want to lose the debug connection
2013-09-24T12:44:47 < jpa-> (in fact, i'm yet to find a tool that would work as reliably as the st's own flash utility does on windows; but it is probably just a matter of figuring the proper set of switches for openocd)
2013-09-24T12:45:36 < jpa-> karlp: i was confused for many weeks because openocd doesn't automatically set the DBGMCU stuff to work for WFI, like texane does :)
2013-09-24T12:45:46 < jpa-> (i assume that texane does)
2013-09-24T12:45:49 < jpa-> (because it works :)

2013-09-24T13:41:04 < jpa-> indeed :)
2013-09-24T13:41:06 < Laurenceb> http://d24w6bsrhbeh9d.cloudfront.net/photo/5642372_700b.jpg
2013-09-24T13:41:07 < PaulFertser> Same about every other kind of sleep
2013-09-24T13:41:23 < PaulFertser> jpa-: i mean this set of switches is not crazy and it should universally work :)
2013-09-24T13:41:24 < jpa-> PaulFertser: and a bit more if i also want to debug with wfi
2013-09-24T13:41:51 < jpa-> it is totally crazy; it isn't even documented anywhere that is easy to find
2013-09-24T13:42:01 < PaulFertser> jpa-: I think you can debug with wfi if you add some register write to your main() in the firmware itself.
2013-09-24T13:42:08 < jpa-> yes
2013-09-24T13:42:26 < jpa-> though then you cannot easily debug "release" binaries
2013-09-24T13:42:31 < PaulFertser> reset_config seems to be properly documented in the official Info manual, same about "program" that is a little helper for flashing.
2013-09-24T13:42:57 < PaulFertser> Yes, true, then you can issue that write with "mww" in the beginning of the debugging session.
2013-09-24T13:43:10 < jpa-> sure, the commands are documented, but the whole set.. compared with the trivial   "st-flash firmware.bin" or even more trivial "push the button" of the windows app
2013-09-24T13:43:40 < jpa-> more flexibility, sure, but it's still no reason why these couldn't be defaults
2013-09-24T13:43:44 < PaulFertser> Should be obvious :)
2013-09-24T13:44:01 < jpa-> lol, not to me, but i'm a newbie anyway :)
2013-09-24T13:44:56 < jpa-> (ok ok, there was some silly reasons like someone didn't like his processor getting reset etc.)
2013-09-24T13:45:21 < PaulFertser> If connect_assert_srst would be made default, it would upset some boards where there're more than one device on the jtag chain.
2013-09-24T13:45:56 < jpa-> yeah.. i guess documenting this crap would be the better approach
2013-09-24T13:46:16 < PaulFertser> And yes, connecting to a target without changing its current state might help if your target mostly works but then every once in a while hangs.

2013-09-24T13:46:38 < jpa-> but sadly there isn't a good stm32 wiki even now
2013-09-24T13:48:26 < Thorn> openocd, like a lot of open* software, seems to be engineered to make sense to its developers rather than users
2013-09-24T13:49:05 < jpa-> and weight on "its".. if it made sense to developers generally, it would be fine :)
2013-09-24T13:49:39 < jpa-> i guess the fundamental problem is that people aren't really all that excited about flashing their processors, they just want to get it done :)
2013-09-24T13:49:43 < Thorn> well its users are supposed to be developers, like "compiler users"
2013-09-24T13:49:49 < jpa-> yep
2013-09-24T13:52:11 < PaulFertser> Thorn: openocd has a nice info manual, I'm not sure why the users complain, what's wrong with it, what does it miss?
2013-09-24T13:53:17 < PaulFertser> btw, when I sent reworked README* for review, _none_ of the users said anything, I got zero feedback from them.
2013-09-24T13:53:24 < jpa-> because it is 100 pages to read just to do the most basic thing, program your stm32
2013-09-24T13:55:14 < Thorn> I remember reading it, it was a "generally" interesting read, but without a whole lot of relevance to practical problems
2013-09-24T13:55:53 < dongs> lol, openocd is fucking insane
2013-09-24T13:55:54 < Thorn> e.g. commands and switches are documented in such a way that you think "I probably won'd need this" and forget about them
2013-09-24T13:56:04 < dongs> insanity starts off with some bullshit scripting language it uses
2013-09-24T13:56:15 < dongs> and the fact taht none of bundled config files work or make sense
2013-09-24T13:56:23 < dongs> i remember trying to "use" openocd on sam7
2013-09-24T13:56:27 < dongs> it was a fucking mess
2013-09-24T13:56:38 < Thorn> well, most logic design software uses tcl
2013-09-24T13:57:02 < Thorn> it's certainly not the biggest problem
2013-09-24T13:57:02 < dongs> who cares what "mosT" does
2013-09-24T13:57:07 < dongs> sure it is
2013-09-24T13:57:11 < dongs> noone in 2013 uses tcl
2013-09-24T13:57:16 < dongs> hell, noone in 1993 did
2013-09-24T13:57:16 < PaulFertser> It has structure, and so you can just go "info openocd Flash\ Programming"
2013-09-24T13:57:30 < zyp> dongs, I wish that was the case
2013-09-24T13:57:45 < jpa-> actually tcl is probably the part of openocd that i have least problems with :)
2013-09-24T13:57:51 < PaulFertser> dongs: your favourite xilinx ise does
2013-09-24T13:57:56 < zyp> dongs, ever used the xilinx stuff? it's full of tcl
2013-09-24T13:58:12 < dongs> nice try, but I never had to deal with tcl in xilinx ide.
2013-09-24T13:58:16 < PaulFertser> tcl is ok, and scriptability is nice.
2013-09-24T13:58:16 < dongs> maybe im just doing dumb stuff in it.
2013-09-24T13:58:38 < jpa-> 90% of real-world stuff is dumb stuff
2013-09-24T13:58:45 < jpa-> it's great if the dumb stuff can be done easily
2013-09-24T13:58:56 < PaulFertser> dongs: also, current board configs work for me on the boards I tried. And stm32s are properly supported.
2013-09-24T13:59:28 < dongs> well, im not gonna touch openocd, so that doesn't matter. like i said last time i had experience with it was back in sam7 days.
2013-09-24T13:59:37 < PaulFertser> dongs: what was the alternative to Tcl back then when it was very popular?
2013-09-24T13:59:47 < jpa-> lisp!
2013-09-24T13:59:56 < dongs> no idea, but whatever it is, its better htan tcl
2013-09-24T14:00:02 < PaulFertser> Lisp didn't allow one to create small GUI apps easily.
2013-09-24T14:00:12 < dongs> lol.
2013-09-24T14:00:15 < dongs> please, are you talkign about tcltk
2013-09-24T14:00:23 < PaulFertser> Tcl/Tk really kicked ass in those pre-python days.
2013-09-24T14:00:25 < dongs> the aids of GUI toolkits
2013-09-24T14:00:33 < dongs> i suppose if you are comparing it to python, yes.
2013-09-24T14:00:37 < PaulFertser> dongs: what was the alternative?
2013-09-24T14:00:40 < dongs> it's pretty hard to be WORSE than python
2013-09-24T14:00:45 < dongs> tcl fits there perfectly.
2013-09-24T14:01:44 < Thorn> worse than python, contender #1: javascript
2013-09-24T14:01:53 < Thorn> anyway, irrelevant.
2013-09-24T14:03:34 < PaulFertser> Patrice Bellard wrote a simple PC emulator in javascript and said the language is not so bad.
2013-09-24T14:03:49 < Thorn> millions say php is ok
2013-09-24T14:03:51 < Thorn> anyway, irrelevant.
2013-09-24T14:04:26 < PaulFertser> Thorn: have you heard of any real programmer who says php is ok?
2013-09-24T14:04:27 < zyp> my favorite language is better than your favorite language
2013-09-24T14:04:40 < PaulFertser> Fabrice Bellard
2013-09-24T14:04:42 < zyp> all real programmers prefer my favorite language
2013-09-24T14:04:45 < zyp> etc
2013-09-24T14:04:55 < PaulFertser> zyp: no, I do not mean it like that.
2013-09-24T14:05:17 < PaulFertser> It's dongs who tried to start language war blaming Tcl for no reason.
2013-09-24T14:05:25 < zyp> then don't pull the "real programmer" card
2013-09-24T14:05:45 < PaulFertser> http://bellard.org/jslinux/
2013-09-24T14:06:13 < PaulFertser> He is well-known and established in the field, so I guess his opinion matters more than some random php programmer's.
2013-09-24T14:06:18 < karlp> openocd's manual is like make's manual,
2013-09-24T14:06:24 < zyp> PaulFertser, to who?
2013-09-24T14:06:32 < karlp> massive and comprehensive and completley lacking in "start here to do useful shit you actual want to do"
2013-09-24T14:06:36 < zyp> because the only opinion that matters to me is my own.
2013-09-24T14:07:29 < jpa-> i agree, zyp's opinion is what matters
2013-09-24T14:08:50 < PaulFertser> zyp: ok. I do not know how else to do a fast comparison of relative programming language usefullness other than to read what the others have written about it (the slow way would be to use them myself extensively).
2013-09-24T14:09:23 < jpa-> karlp: when i moved from make to scons, it was kind of silly how the age-old difficult thing in make (get dependencies correct) was trivial, whereas the trivial thing in make (define a command to generate .foo from .bar) required reading (only slightly more difficult, though)
2013-09-24T14:10:21 < zyp> :)
2013-09-24T14:10:23 < PaulFertser> I feel comfortable with the make manual. It seems to be structured well and not lacking.
2013-09-24T14:10:37 < karlp> now that you know how make works and you are looking for specifics
2013-09-24T14:10:46 < karlp> same with openocd now that I know how to use it
2013-09-24T14:10:53 < jpa-> yeah, i've been fine with make manual also, but it wouldn't have been as helpful when i was beginning with makefiles
2013-09-24T14:11:04 < karlp> but worse than terrible when I didn't know what I was doing yet.
2013-09-24T14:11:13 < Thorn> http://www.gnu.org/software/make/manual/make.html#Prerequisite-Types took me months to figure out literally lol
2013-09-24T14:11:16 < karlp> same with gdb
2013-09-24T14:11:35 < Thorn> i.e. why make recompiles half of source files that aren't changed every time
2013-09-24T14:12:52 < Thorn> because you wouldn't go searching for 'order-only prerequisites' in that case, would you? (although I'm sure RMS might)

2013-09-24T20:12:29 < mtbg> it detects 8192kB of flash instead of 1024kB and is unable to unlock the flash sectors for write
2013-09-24T20:12:58 < mtbg> setting the bank size manually helps, i.e. there are correct sector sizes and numbers
2013-09-24T20:13:12 < mtbg> but writing still doesn't work
2013-09-24T20:17:03 < Thorn> what's the revision code on the stm32?
2013-09-24T20:17:20 < Thorn> is it some new revision?
2013-09-24T20:19:02 < mtbg> probably
2013-09-24T20:19:20 < mtbg> I can't find in the datasheet which part of the number is the revision number
2013-09-24T20:19:55 < mtbg> STM32F4xx - Rev: Z
2013-09-24T20:20:06 < mtbg> that is what oocd says about it
2013-09-24T20:24:43 < Thorn> should be the rightmost character in the second line
2013-09-24T20:27:45 < mtbg> Z, the same as the one which works
2013-09-24T20:28:03 < Thorn> I've got A there (mb997b)
2013-09-24T20:28:10 < Thorn> does that chip work with st-link?
2013-09-24T20:28:23 < Thorn> i.e. are you sure it's not a faulty chip?
2013-09-24T20:29:37 < mtbg> it's brand new discovery board, there is no reason for it to be faulty, especially as it does respond for other commands
2013-09-24T20:29:47 < mtbg> https://forum.sparkfun.com/viewtopic.php?f=18&t=36085
2013-09-24T20:29:54 < mtbg> I found something similar
2013-09-24T20:30:15 < mtbg> where can I get the software that is mentioned there (ST-Utility)?
2013-09-24T20:30:39 < Thorn> that's what I've been talking about
2013-09-24T20:30:49 < Thorn> it's somewhere on st.com
2013-09-24T20:31:48 < Thorn> http://www.st.com/web/catalog/tools/FM146/CL1984/SC724/SS1677/PF251168 has links to driver and utility

2013-09-24T22:04:11 < rlc> anyone used sram to extend their memory?
2013-09-24T22:04:39 < ABLomas> own memory?
2013-09-24T22:05:09 < Thorn> do want
2013-09-24T22:05:22 < rlc> external sram
2013-09-24T22:05:26 < Thorn> how do I find out what interface I have
2013-09-24T22:06:28 < rlc> I'm not sure how I would choose the appropriate sram to match the stm32f4 series
2013-09-24T22:06:45 < rlc> Size I need would be 4mbit
2013-09-24T22:07:31 < zyp> just choose one?
2013-09-24T22:08:02 < Thorn> data bus width would be about the only variable
2013-09-24T22:08:05 < rlc> what speed should I choose for example?
2013-09-24T22:08:25 < rlc> there are 70 ns, 50 ns, etc
2013-09-24T22:08:26 < zyp> I believe that the memory controller is flexible enough to work with pretty much anything
2013-09-24T22:09:32 < rlc> I am pretty much a noob with ram chips
2013-09-24T22:10:10 < zyp> it's not exactly rocket science
2013-09-24T22:11:15 < zyp> but of course, the slower chip you get, the worse performance you'll have
2013-09-24T22:11:49 < mtbg> the sram devices are awfully expesive
2013-09-24T22:12:08 < mtbg> the biggest I found, 4MB, was 40 euro in mouser
2013-09-24T22:12:17 < mtbg> and it was the cheapest of that size
2013-09-24T22:12:33 < mtbg> PSRAM are a bit cheaper and fsmc can do them too
2013-09-24T22:12:38 < rlc> Not so much as I can see on Digikey
2013-09-24T22:13:29 < rlc> As an example, 4M is only $4
2013-09-24T22:13:34 < rlc> http://www.digikey.ca/product-detail/en/AS6C4008-55STIN/1450-1029-ND/4234588
2013-09-24T22:14:25 < Thorn> that one is pretty slow (55ns)
2013-09-24T22:17:33 < Thorn> http://www.digikey.ca/product-detail/en/IS61WV25616BLL-10TLI/706-1106-ND/1831299 - 16 bit wide, 10ns
2013-09-24T22:18:28 < Thorn> http://www.digikey.ca/product-detail/en/IS61WV5128EDBLL-10TLI/706-1147-ND/2799145 - same thing, 8 bits
2013-09-24T22:19:44 < rlc> What whould be the advantage of using 8 bit wide vs 16 bit wide?
2013-09-24T22:20:02 < jpa-> 8 bit is less wires, 16 bit is faster
2013-09-24T22:20:04 < Thorn> 16 bits is twice as fast, 8 more pins / traces
2013-09-24T22:21:43 < rlc> Then I shall choose 16 bit
2013-09-24T22:21:45 < mtbg> there are stm32 devices supporting dynamic memories
2013-09-24T22:21:54 < mtbg> where 64MB costs 2 usd
2013-09-24T22:22:04 < rlc> Are they out yet?
2013-09-24T22:22:55 < rlc> I mean on Digikey

2013-09-25T02:08:42 < GargantuaSauce> that is a lot...perhaps they just had the room on the die and had to do something with it

2013-09-25T02:49:55 < dongs> on that thing
2013-09-25T02:51:17 < gxti> it's amusing that not only can you not use a 6.3V cap at 5v, but if you do it has a nontrivial chance of failing explosively, and yet they can still get away with rating it that way
2013-09-25T02:52:49 < gxti> or that using a high-value ceramic near its rating can kill 80% of its capacitance

2013-09-25T04:31:29 < GargantuaSauce> vdpau actually rules, i get better video decode performance in the sauce than in windows
2013-09-25T04:31:54 < dongs> lol.
2013-09-25T04:32:02 < dongs> ya on all 2 supported cards.
2013-09-25T04:32:15 < dongs> meanwhile dxva works on windows *EVERYWHERE*
2013-09-25T04:33:04 < dongs> and by "supported" i mean "evil binary blobs" from dirty manufactureres who refuse to give out their trade secrets to filthy opensorcererrs.
2013-09-25T04:33:19 < GargantuaSauce> :)
2013-09-25T04:38:50 < dongs> any shithub experts?
2013-09-25T04:38:57 < dongs> i have a local repo w/change history etc (never been online).
2013-09-25T04:39:01 < dongs> how do I push it all to shithub?
2013-09-25T04:39:43 < gxti> after you create the repo it will give you instructions
2013-09-25T04:40:02 < dongs> i already created it
2013-09-25T04:40:07 < GargantuaSauce> git remote add
2013-09-25T04:40:28 < gxti> in github, after you create the repo. it should show you what to do after.
2013-09-25T04:40:32 < dongs> oh
2013-09-25T04:40:33 < dongs> ok lemme try
2013-09-25T04:40:47 < GargantuaSauce> i am pleased to hear you're branching out from svn!
2013-09-25T04:40:50 < GargantuaSauce> ...so to speak
2013-09-25T04:40:53 < gxti> but yeah, git remote add origin shithub.com then git push
2013-09-25T04:40:58 < gxti> essentially.
2013-09-25T04:41:06 < dongs> i use a gui
2013-09-25T04:41:07 < dongs> im not a faggot
2013-09-25T04:41:26 < gxti> then click on shit until it works
2013-09-25T04:41:57 < gxti> i'm surprised there isn't a "post on github cuz i'm a moron" button already
2013-09-25T04:44:08 < ds2> click on shit til it works?
2013-09-25T04:44:15 < gxti> that's how guis usually work
2013-09-25T04:44:17 < ds2> }:-)

2013-09-25T05:41:06 < dongs> resistor network?
2013-09-25T05:41:09 < dongs> they look giant tho
2013-09-25T05:41:26 < R2COM> those are connector header places
2013-09-25T05:41:34 < dongs> wat
2013-09-25T05:41:39 < dongs> no im talkin about shit all over the CPLD
2013-09-25T05:41:46 < R2COM> yes resistors
2013-09-25T05:42:24 < dongs> why u no use 0804

2013-09-25T05:45:08 < dongs> finally got pcba quote

2013-09-25T05:47:12 < dongs> 0804 RN is like 0201 or something x 4
2013-09-25T05:47:17 < dongs> or 0402x4 i dont remember

2013-09-25T05:48:06 < R2COM> ah
2013-09-25T05:48:23 < R2COM> well yes 2x1
2013-09-25T05:48:39 < R2COM> wonder how wolderable that is
2013-09-25T05:48:45 < dongs> im using them on my shit.
2013-09-25T05:48:48 < dongs> machine-placed tho
2013-09-25T05:48:56 < dongs> it just picks them up as 0805 resistor
2013-09-25T05:49:09 < R2COM> I think 0805 is reasonably small
2013-09-25T05:49:45 < dongs> 1206 RN is even more "hand" solderable
2013-09-25T05:49:59 < dongs> but yours looks even bigger than that

2013-09-25T05:50:23 < dongs> 2012 lolol
2013-09-25T05:50:24 < dongs> that is HUGE
2013-09-25T05:51:19 < R2COM> I think I used it cuz of power handling
2013-09-25T05:52:06 < dongs> yeah im sure you need high power handling out of CPLD GPIO
2013-09-25T05:52:11 < R2COM> if one has long cable which loads line with capacitance + high rate, it draws more power

2013-09-25T05:56:20 < R2COM1> cpld has IO output curves, with vout versus current
2013-09-25T05:56:38 < R2COM1> and that specific one can do up to 70mA at lower than 3.3v voltages
2013-09-25T05:56:44 < dongs> per pin?
2013-09-25T05:57:07 < R2COM1> i said IO output curve...per fucking what else it could be

2013-09-25T05:58:49 < R2COM1> its still might be a bit of overdesign, 125mW handling of power, but thats what I found at that time, all others were too small
2013-09-25T05:58:53 < R2COM1> which is why i chosen it
2013-09-25T05:59:32 < R2COM1> for specific designs in which i know i use only short cable or trace with low capacitance, I'd choose lower power rating resistor
2013-09-25T06:01:00 < R2COM1> anyhow... for most parts I'll use that 0805 shit
2013-09-25T06:01:52 < dongs> > anyway im mainly just exadurating because its funny to watch timecop rage on avrduino

2013-09-25T06:05:47 < R2COM1> that shit will be easy target for very old air defence missiles
2013-09-25T06:06:13 < R2COM1> and price for each of those ancient missiles is 10000x less than this toying project
2013-09-25T06:06:15 < dongs> well, apparently it can maneuver at 9Gs to avoid missiles, so like, better htan a pilot can
2013-09-25T06:06:31 < GargantuaSauce> its not automated
2013-09-25T06:06:35 < GargantuaSauce> it's remotely piloted
2013-09-25T06:06:38 < R2COM1> first of all... its not going to avoid anything.
2013-09-25T06:06:41 < R2COM1> to start with.
2013-09-25T06:06:45 < dongs> says who
2013-09-25T06:06:53 < R2COM1> statistics says that.
2013-09-25T06:08:28 < R2COM1> most aa missiles of todays are much smaller and maneur with much more g's, theres now way this huge aircraft tricks them out with its 9g maneur capability.
2013-09-25T06:09:09 < R2COM1> looks like a dead project to me.
2013-09-25T06:09:35 < dongs> they could just remotely fly them into new WTC
2013-09-25T06:09:42 < dongs> and start brand new war on terror
2013-09-25T06:10:21 < R2COM1> cost of reviving it + cost of modernizing it is more than some small speciallized uav
2013-09-25T06:10:31 < R2COM1> and that thing can be easily shot
2013-09-25T06:10:38 < R2COM1> with very old systems
2013-09-25T06:10:45 < R2COM1> so i dont see a point

2013-09-25T08:17:20 < dongs> mkay time to plop down bga and oven
2013-09-25T08:24:21 < emeb_mac> burn baby burn
2013-09-25T08:24:51 < emeb_mac> so who's got the best STM32F3xx I2C code?
2013-09-25T08:25:15 < emeb_mac> need some basic read/write code to talk to an EEPROM
2013-09-25T08:25:40 < dongs> i've got the best bitbanged one
2013-09-25T08:25:44 < dongs> which is all youll ever need for eeprom
2013-09-25T08:26:03 < dongs> https://code.google.com/p/afrodevices/source/browse/trunk/baseflight/src/drv_i2c_soft.c
2013-09-25T08:26:13 < emeb_mac> thanks!
2013-09-25T08:26:24 < emeb_mac> is bitbang better than using the I2C hardware?
2013-09-25T08:26:42 < dongs> if you want shit ot just work, sure
2013-09-25T08:26:51 < dongs> or you can spend forever dicking
2013-09-25T08:27:04 < dongs> plus that one works on f103/303/40x/wahtever
2013-09-25T08:27:12 < dongs> while each one of those has some different bullshit hardware quirks
2013-09-25T08:27:21 < dongs> in i2c
2013-09-25T08:27:37 < emeb_mac> so I've heard

2013-09-25T08:37:28 < dongs> i guess i should try powering it up.
2013-09-25T08:37:59 < emeb_mac> the moment of truth
2013-09-25T08:39:41 < dongs> no smoke and nothing how
2013-09-25T08:39:42 < dongs> hot
2013-09-25T08:39:43 < dongs> so maybe ok ;d
2013-09-25T08:41:01 < emeb_mac> good start.
2013-09-25T08:41:16 < emeb_mac> supply voltages nominal? clocks running?
2013-09-25T08:41:36 < dongs> ya i need to solder header and try it wiht xilinx shit in a minute
2013-09-25T08:41:43 < dongs> http://i.imgur.com/nPuuIlc.jpg
2013-09-25T08:43:48 < emeb_mac> nice
2013-09-25T08:43:56 < emeb_mac> but no STM32 - wtf?
2013-09-25T08:44:05 < dongs> i kno rite.
2013-09-25T08:44:29 < emeb_mac> what's that cypress part?
2013-09-25T08:44:41 < emeb_mac> some sort of asi mac?
2013-09-25T08:46:01 < dongs> ASI rx
2013-09-25T08:46:17 < dongs> or SDI or whatever
2013-09-25T08:46:28 < dongs> basically a fancy expensive 8/10b deserializer
2013-09-25T08:47:19 < emeb_mac> right
2013-09-25T08:48:00 < emeb_mac> and the little chip between it and the board-edge connector is the input buffer?
2013-09-25T08:48:40 < dongs> yeah thats 'cable equalizer'
2013-09-25T08:48:42 < dongs> also ripoff shit
2013-09-25T08:49:35 < emeb_mac> oh right - some kind of crazy analog eq.
2013-09-25T08:49:40 < dongs> k time to hook it up to impact and see if it works
2013-09-25T08:49:58 < emeb_mac> ya
2013-09-25T08:50:11 < emeb_mac> simple just to probe and see if it spots it on the bus

2013-09-25T08:53:36 < dongs> cant start impact withoput making new project??
2013-09-25T08:53:37 < dongs> trash
2013-09-25T08:54:35 < emeb_mac> impact is very crufty
2013-09-25T08:54:44 < emeb_mac> been around for _ages_
2013-09-25T08:54:55 < emeb_mac> crashes a lot too...
2013-09-25T08:54:55 < dongs> yeah ive used it in like 2001
2013-09-25T08:54:58 < dongs> with some parallel port adapter
2013-09-25T08:56:20 < dongs> ugh wtfak
2013-09-25T08:56:32 < dongs> im not making a fucking project WITH sores
2013-09-25T08:56:33 < dongs> to test this shit
2013-09-25T08:57:33 < emeb_mac> shouldn't need that
2013-09-25T08:57:39 < dongs> i do
2013-09-25T08:57:40 < dongs> its ok
2013-09-25T08:57:42 < dongs> added a buffer
2013-09-25T08:57:44 < dongs> into schematic entry.
2013-09-25T08:57:45 < dongs> and 2 pins.
2013-09-25T08:57:48 < dongs> haha.
2013-09-25T08:57:49 < emeb_mac> wtf?
2013-09-25T08:58:06 < emeb_mac> never had to do that before
2013-09-25T08:58:17 < dongs> No iMPACT project file exists. Click OK to open iMPACT. You will then need to define a configuration chain, designate which device in that chain is the target device, and then save the iMPACT project file. Once this step is completed, subsequent runs of the 'Configure Target Device' process can program the target device without needing to open the iMPACT GUI.
2013-09-25T08:58:22 < dongs> lool
2013-09-25T08:58:55 < emeb_mac> yeah, that. but don't need an ISE project or source/etc.

2013-09-25T08:59:31 < dongs> yeah but I dont have impact shit in start menu or anywhere
2013-09-25T08:59:37 < dongs> i can only go ise tools->impact
2013-09-25T08:59:41 < emeb_mac> ya
2013-09-25T08:59:42 < dongs> and that needs a fully buildable project
2013-09-25T08:59:48 < dongs> at least in wahtever latest garbage i downloaded
2013-09-25T08:59:53 < emeb_mac> meh
2013-09-25T09:00:14 < emeb_mac> should be able to get to it from the windows start menu->Xilinx->mumblemumble
2013-09-25T09:00:44 < emeb_mac> or browse the filesystem w/ explorer
2013-09-25T09:00:52 < emeb_mac> finde impact.exe & run.
2013-09-25T09:01:10 < dongs> haha, its not that easy.
2013-09-25T09:01:19 < dongs> latest ise uses some bullshit batch files and loader .exe
2013-09-25T09:01:21 < dongs> to start all shit
2013-09-25T09:01:39 < emeb_mac> fuck that
2013-09-25T09:01:49 < emeb_mac> what version is this?
2013-09-25T09:01:59 < dongs> P.68d
2013-09-25T09:02:10 < dongs> and ISE uh..14.6?
2013-09-25T09:02:25 < emeb_mac> Ok - I'm still on 13.1 or something.
2013-09-25T09:02:32 < emeb_mac> glad I haven't updated for a while
2013-09-25T09:02:44 < dongs> erase succeeded
2013-09-25T09:02:51 < dongs> DONE led is on
2013-09-25T09:02:53 < dongs> i guess i didnt fail too badly
2013-09-25T09:03:02 < emeb_mac> huh?
2013-09-25T09:03:04 < dongs> ill try to poke through some HDL to make the rest of the stuff work later.
2013-09-25T09:03:19 < emeb_mac> Done LED on? did you load a valid config?
2013-09-25T09:03:24 < dongs> no, i erased all
2013-09-25T09:03:32 < emeb_mac> bizarre
2013-09-25T09:03:57 < emeb_mac> I've only ever seen DONE when there's a valid bitstream loaded.
2013-09-25T09:04:17 < emeb_mac> Oh - you've got a 3AN, right>
2013-09-25T09:04:40 < dongs> ya
2013-09-25T09:04:47 < emeb_mac> that needs to install a bitstream to talk to the integrated flash
2013-09-25T09:04:53 < emeb_mac> makes sense now
2013-09-25T09:04:58 < dongs> yeah
2013-09-25T09:04:59 < dongs> i saw it doing that
2013-09-25T09:05:02 < dongs> loading some SPI core
2013-09-25T09:05:03 < dongs> or someshit
2013-09-25T09:05:06 < emeb_mac> yep
2013-09-25T09:06:18 < emeb_mac> what did you do for the supplies on the FPGA? Looks like you've got some dual switcher over on the right side.
2013-09-25T09:06:24 < dongs> yeah
2013-09-25T09:06:26 < dongs> just 1.2V
2013-09-25T09:06:30 < dongs> like 600mA or whatever max on that.
2013-09-25T09:06:33 < dongs> and 3.3V for IO.
2013-09-25T09:06:38 < dongs> im not planning to run anything crazy on it. it should be fine
2013-09-25T09:07:03 < emeb_mac> shouldn't need that much on the 1.2V unless you're running real fast and have most of the fabric used.
2013-09-25T09:07:36 < emeb_mac> what's the switcher part? Looking for something myself.
2013-09-25T09:07:42 < dongs> NCP1532 i think
2013-09-25T09:07:53 < ds2> maybe he has a lot of ring oscillators defined ;)
2013-09-25T09:08:00 < dongs> ya that. i've been using them in a few projects
2013-09-25T09:08:13 < dongs> useful part, and shares common R1/R2 with single NCP switcher I use
2013-09-25T09:08:21 < emeb_mac> cool. thx
2013-09-25T09:09:32 < jpa-> lols @ arduinos catching fire
2013-09-25T09:10:45 < dongs> hm, i should be able to view the cypress chip with imapct too right?
2013-09-25T09:10:48 < dongs> at least get ID or something?
2013-09-25T09:12:24 < emeb_mac> maybe
2013-09-25T09:12:34 < dongs> there's a bsdl file for it
2013-09-25T09:12:37 < dongs> seems impact can use that
2013-09-25T09:13:17 < emeb_mac> never messed with bsdl files & non-xilinx parts in the chain.
2013-09-25T09:13:38 < dongs> nah its not in chain
2013-09-25T09:13:42 < dongs> i made separate jtag header for it
2013-09-25T09:13:48 < dongs> fully expecting it not to work :)
2013-09-25T09:14:01 < dongs> i just wanna see if I can read ID or something.
2013-09-25T09:14:11 < emeb_mac> easy to try
2013-09-25T09:15:05 < dongs> dumb.
2013-09-25T09:15:16 < dongs> it wouldnt accept .bsdl file but showerd some cryptic error msg

2013-09-25T13:05:29 < Laurenceb> so the guy who said it was smart to use undocumented binary protocols for talking to dataloggers has now left
2013-09-25T13:05:42 < Laurenceb> leaving the protocol undocumented...

2013-09-25T13:07:55 < zyp> 04:45:08 < dongs> finally got pcba quote
2013-09-25T13:07:57 < dongs> ya
2013-09-25T13:07:58 < zyp> that for my stuff?
2013-09-25T13:08:00 < dongs> right
2013-09-25T13:08:02 < dongs> and some parts quotes
2013-09-25T13:08:06 < dongs> though onl stm32 is interesting
2013-09-25T13:08:10 < dongs> rest is fairly fail
2013-09-25T13:08:18 < dongs> i thought they could get a good deal on dip sockets
2013-09-25T13:08:24 < dongs> but looks like digikey w/some trolling should do better
2013-09-25T13:08:46 < dongs> and I doubt y ou want china version of that 1A reg
2013-09-25T13:08:49 < dongs> but its only $0.10!
2013-09-25T13:09:33 < zyp> why? doesn't it work?
2013-09-25T13:09:34 < dongs> there's 2 quotes, pcb in production panel and as 'sample'
2013-09-25T13:09:38 < dongs> sure it does
2013-09-25T13:09:50 < dongs> with sample you get ~100ish exactly, wiht production you get like 120 or so
2013-09-25T13:09:55 < dongs> but cheaper
2013-09-25T13:10:09 < dongs> so we can just toss the extras or send you blanks or something.
2013-09-25T13:11:04 < zyp> or just assemble all, 100 is just a number I picked
2013-09-25T13:11:38 < dongs> lemme forward you their fail
2013-09-25T13:11:44 < zyp> sure
2013-09-25T13:11:50 < dongs> i had to fucking bitch like 5 times today to get it done
2013-09-25T13:11:55 < dongs> first they sent quote white pcb/black silk
2013-09-25T13:11:58 < dongs> then fucked up stencil count
2013-09-25T13:12:02 < dongs> then fucked up qty

2013-09-25T13:25:56 < dongs> zyp: ya, and it's going to be at least few extra on top of that usually.
2013-09-25T13:26:03 < dongs> In this paper, the wind turbine ismodelled after a horizontal-axis wind turbine (HAWT)
2013-09-25T13:26:59 < zyp> dongs, by the way, do they normally keep stencils in case I want to do another batch later?
2013-09-25T13:28:23 < dongs> yeah, its there forever
2013-09-25T13:28:27 < dongs> and can be reused.
2013-09-25T13:28:47 < dongs> you can have it too if you want but its about 1m^2
2013-09-25T13:28:48 < zyp> good to know
2013-09-25T13:28:53 < zyp> heh
2013-09-25T13:29:36 < dongs> anyway STM32 is 4.60
2013-09-25T13:29:48 < dongs> RBT6
2013-09-25T13:30:14 < dongs> 2N7002P is like 3c

2013-09-25T13:30:53 < Robint91> STM32F103RBT?
2013-09-25T13:30:55 < dongs> Robint91: the one hes using.
2013-09-25T13:30:58 < dongs> F303RB
2013-09-25T13:32:20 < dongs> i could try poking the place we got previous tray from but they only take real money so they're a bit annoying to deal with
2013-09-25T13:32:53 < dongs> oo, hmm, they have it for 3.89
2013-09-25T13:33:04 < dongs> but realmoney :(
2013-09-25T13:33:28 < Laurenceb> obvious jew is obvious
2013-09-25T13:35:26 < dongs> actually 4.06 @ 100 so probly not worth the trouble.

2013-09-25T13:35:42 < dongs> i think thats what we paid last time too.
2013-09-25T13:36:16 < zyp> so, how much am I looking at in total for parts?
2013-09-25T13:36:41 < dongs> well, STM + passives+crap can be picked up locally. passives are gonna be mostly free at these qtys.
2013-09-25T13:36:45 < zyp> I think I counted $12/board for the ones I assembled myself, so I assume this will be a bit less
2013-09-25T13:36:49 < dongs> but connectors... digikey seems to be doing good.
2013-09-25T13:36:51 < dongs> yeah
2013-09-25T13:37:11 < dongs> 4.60 for stm + wahtever for headers, .50? for USB + ??? < $1 for passives
2013-09-25T13:37:22 < zyp> so all in all I'm looking at <$2000 total, that sounds good
2013-09-25T13:38:18 < dongs> yeah, sounds about right
2013-09-25T13:38:25 < dongs> dickstart it after the fact.
2013-09-25T13:38:29 < dongs> just for free advertisement.
2013-09-25T13:38:37 < Laurenceb> what are you making?

2013-09-25T13:38:52 < zyp> usb hid adapters
2013-09-25T13:39:01 < dongs> btw,
2013-09-25T13:39:02 < Laurenceb> wut for?
2013-09-25T13:39:03 < dongs> your parts list
2013-09-25T13:39:06 < dongs> and prototype
2013-09-25T13:39:10 < dongs> parts had 2x 2pin connectors
2013-09-25T13:39:13 < dongs> but prototype only 1?
2013-09-25T13:39:17 < dongs> did you add another one somewehre?
2013-09-25T13:39:20 < dongs> or did i miss it
2013-09-25T13:39:22 < zyp> huh?
2013-09-25T13:39:30 < dongs> parts list for dicknplace
2013-09-25T13:39:33 < dongs> had 2 2 pin connectors
2013-09-25T13:39:34 < zyp> ah, yeah, I added another
2013-09-25T13:39:36 < dongs> for LED shit
2013-09-25T13:39:56 < zyp> http://bin.jvnv.net/f/iCoDD.png vs http://bin.jvnv.net/f/SdoRn.png
2013-09-25T13:40:20 < zyp> difference is mainly that and the spi breakout
2013-09-25T13:40:27 < zyp> and fixing wrong footprints
2013-09-25T13:40:48 < dongs> ok.
2013-09-25T13:41:06 < dongs> how did you end up making hte proto?
2013-09-25T13:41:09 < dongs> snip offthose bottom pins?
2013-09-25T13:41:14 < zyp> yeah
2013-09-25T13:41:29 < dongs> now just add a shitload of rgb leds
2013-09-25T13:41:32 < dongs> you got space
2013-09-25T13:41:35 < dongs> and i've got a reel of htem
2013-09-25T13:42:01 < Laurenceb> what plugs into this thing?
2013-09-25T13:42:18 < zyp> Laurenceb, pushbuttons with leds
2013-09-25T13:42:31 < Laurenceb> oh - this is for arcade?

2013-09-25T13:42:58 < dongs> aidsfruit still hasnt reeleased displayport adapter
2013-09-25T13:42:59 < Thorn> no esd protection
2013-09-25T13:43:00 < dongs> a i d s
2013-09-25T13:43:12 < zyp> Thorn, I know, I considered adding it
2013-09-25T13:43:12 < dongs> ESD? in MY boards? Less likely than you think
2013-09-25T13:43:31 < dongs> Thorn: he probably wont be selling these to furries
2013-09-25T13:43:33 < dongs> so its ok
2013-09-25T13:43:42 < zyp> Thorn, if it turns out to be a problem, I'll fix that in the next revision
2013-09-25T13:43:43 < dongs> rubbin them boards

2013-09-25T13:44:14 < dongs> old?
2013-09-25T13:45:52 < zyp> dongs, anyway, the price sounds acceptable, so just go ahead, if 112 boards is the normal volume per panel, just assemble 112
2013-09-25T13:46:33 < dongs> OK. yeah, they can assemble whatever extras exist w/parts that are available
2013-09-25T13:46:41 < zyp> I'd like one board without the XH connectors, that I can make into a test jig for other boards
2013-09-25T13:47:07 < zyp> (and without fets if that's not too much work, otherwise I'll just pick them off myself with a tweezer iron)
2013-09-25T13:47:56 < dongs> ya that can be arranged
2013-09-25T13:48:13 < dongs> if not to much work can you email that shit back to me, and i'll just fwd to them
2013-09-25T13:48:53 < dongs> i mean specific  assembly instruction + etc
2013-09-25T13:49:03 < Laurenceb> hehe http://www.adafruit.com/products/912

2013-09-25T13:51:48 < dongs> zyp: yeah so i dont have to copypaste shit
2013-09-25T13:51:52 < dongs> and any other instruction to pass on
2013-09-25T13:53:07 < zyp> there
2013-09-25T13:54:08 < dongs> OK
2013-09-25T13:54:53 < dongs> is STM32 price oK? if so, ill pickup everythign else from there
2013-09-25T13:55:05 < dongs> else = passives + shit
2013-09-25T13:55:13 < zyp> yes, $4.2 sounds good

2013-09-25T13:57:49 < zyp> ah, right
2013-09-25T13:57:51 < dongs> but they'll want fedex shipping and bla bla, so it will end up about same if not worse

2013-09-25T13:58:33 < dongs> yeah.
2013-09-25T13:59:25 < dongs> only remaining thing is all those connectors, ill chat up digikey and see if I can get them to give a deal on it
2013-09-25T13:59:38 < dongs> or else you can pick them up and send.
2013-09-25T14:00:05 < dongs> hk price on them sucks.
2013-09-25T14:00:19 < zyp> me doing shit means 25% norwegian import tax on top of whatever price I can get it for :p
2013-09-25T14:02:05 < Laurenceb> better than UK
2013-09-25T14:02:25 < Laurenceb> i seem to end up with like 140% import tax
2013-09-25T14:02:50 < Laurenceb> they compound VAT and numerous import duties ontop of one another
2013-09-25T14:03:09 < Laurenceb> luckily half the time they dont seem to bother taxing at all

2013-09-25T14:04:20 < Thorn> in russia you may need to visit customs like 5 times to get your package released. worse than any tax (which is 30% max iirc)
2013-09-25T14:05:29 < Thorn> oh and private persons apparently can't import oscilloscopes and other lab equipment. (most do get through because customs is fortunately inefficient.)
2013-09-25T14:05:58 < Thorn> new lab equipment that is
2013-09-25T14:07:02 < Thorn> you likely can't import anything with hardware crypto such as stm32f417 etc. too

2013-09-25T14:47:24 <@Tectu> I start worrying...
2013-09-25T14:47:31 <@Tectu> I have some 6V3 tantalum on my 5V rail
2013-09-25T14:48:22 < ohsix> they smell good
2013-09-25T14:48:53 < dongs> oh i know waht i forgot to ask digikey
2013-09-25T14:49:03 < dongs> what is that crimp shit they use to make digireels and if they sell it separately
2013-09-25T14:49:04 < Claude> inrush kills most of the tantals
2013-09-25T14:50:33 <@Tectu> inrush?
2013-09-25T14:52:05 < Claude> yeah current inrush
2013-09-25T14:52:57 < Claude> tantal cap is at 0v , psu at 12V . psu is allready running and you plug in your circuit -> boom :)
2013-09-25T14:53:34 < Claude> there are automotive tantal caps , iirc they have an current limiting resistor allready build in
2013-09-25T14:53:41 < dongs> digikey chatter is on it.
2013-09-25T14:53:59 < dongs> "I have to do some research"
2013-09-25T14:54:13 < Claude> or just use the softstart feature of your dc/dc converter

2013-09-25T14:55:35 < dongs> and why they even used that instead of a bunch of cheap chink aluminum caps

2013-09-25T14:57:00 <@Tectu> congratulations
2013-09-25T14:57:15 < Fornaxian> now to setup the toolchain.
2013-09-25T14:57:21 <@Tectu> good luck
2013-09-25T14:57:21 < Fornaxian> that's tonight's project.

2013-09-25T20:07:20 <@Tectu> no
2013-09-25T20:09:41 < Thorn> max31855 or op amp + stm32f3?
2013-09-25T20:11:35 < emeb> depends on cost, power, area.
2013-09-25T20:11:44 < gxti> microchip makes a nice adc for thermocouples, 18+ bit with 8x gain
2013-09-25T20:12:22 < gxti> cheaper than the max of course, but don't forget you need a cold junction sensor (can just be a thermistor but the positioning is important)
2013-09-25T20:13:36 < Thorn> there's a "zero drift" op amp recommended for thermocouples but it costs the same as the max31855
2013-09-25T20:14:11 < Thorn> ad8551
2013-09-25T20:14:59 < Thorn> and an external adc is probably an overkill, I'd like to use the 16-bit adc in f3
2013-09-25T20:15:30 < gxti> this is from before i started doing stm32 http://hg.partiallystapled.com/circuits/tcdisplay/raw-file/2045cb4d129a/out/tcdisplay/production.PDF
2013-09-25T20:15:31 < Thorn> cold junction sensor could be a ds18b20
2013-09-25T20:16:12 < gxti> it's also the only 5v microcontroller board i've done, just worked out easier that way
2013-09-25T20:16:55 < gxti> not especially proud of it but i still use it (toaster oven reflow ololol)
2013-09-25T20:17:05 < emeb> wonder if you can calibrate the drift out using the on-chip temp sensor in the F3 and use a cheap op-amp.
2013-09-25T20:18:02 < GargantuaSauce> jpa-: how's that temperature graph gonna work without being obscenely slow if you don't have enough memory for a framebuffer?
2013-09-25T20:18:22 < jpa-> GargantuaSauce: it's going to update once a minute anyway
2013-09-25T20:18:37 < GargantuaSauce> hehe guess that works
2013-09-25T20:18:58 < jpa-> (or maybe even longer than that.. i'll have to see power consumption)
2013-09-25T20:19:18 < jpa-> and anyway, it'll only have to add a very short segment of line every time :)
2013-09-25T20:19:30 < karlp> what temp grtaph?
2013-09-25T20:20:14 < jpa-> just this http://www.youtube.com/watch?v=jtGE7zh8YzE
2013-09-25T20:20:42 < jpa-> a bit slow on stm32l1 and ugfx.. due to that ugfx wants to write immediately to display and i have very little memory to buffer the writes
2013-09-25T20:21:59 < Thorn> gain 8 seems small for a thermocouple
2013-09-25T20:24:16 < trepidaciousMBR> jpa-: If I wanted a physically small and cheap STM32 to run chibios with a few KB spare SRAM after ChibiOS, and half-duplex one-wire UART, what would you recommend? Is the L1 any good?
2013-09-25T20:25:06 < jpa-> L1 is nice, i guess you could manage with F0 also
2013-09-25T20:26:51 < karlp> f100 too, why does everyone hate on the f100?
2013-09-25T20:26:56 <+Steffanx> Im kind of surprised you use µGFX jpa- . .. but nice!
2013-09-25T20:27:32 < jpa-> Steffanx: well i'm lazy; that's why :D
2013-09-25T20:27:40 < jpa-> otherwise i would have had to write my own graphics library
2013-09-25T20:27:50 < jpa-> and invent my own totally idiotic license for it
2013-09-25T20:28:09 < jpa-> and pay a lawyer to steal some pants
2013-09-25T20:28:18 < GargantuaSauce> it's actually pretty fun if you ask me
2013-09-25T20:28:25 < trepidaciousMBR> jpa-: ugfx doesn't work on f100? ChibiOS is supported though?
2013-09-25T20:28:35 < emeb> karlp - f100 is fine. I designed a product with it: http://ebrombaugh.studionebula.com/synth/e355/index.html
2013-09-25T20:28:37 < jpa-> trepidaciousMBR: why wouldn't it?
2013-09-25T20:28:42 < GargantuaSauce> extending bresenham's algorithm to rasterize a triangle was one of the most enjoyable bits of coding i've done
2013-09-25T20:28:51 < trepidaciousMBR> jpa-: Ah I was reading the wrong response :)
2013-09-25T20:28:53 < jpa-> karlp: f100 has the stupid gpio :)
2013-09-25T20:29:24 < jpa-> GargantuaSauce: yes, it is pretty fun; but it takes time :)
2013-09-25T20:29:27 < trepidaciousMBR> GargantuaSauce: Stealing adafruit's library for doing that was the most fun I've had for a while ;)
2013-09-25T20:29:40 <+Steffanx> adafruit .. dont mention that here trepidaciousMBR
2013-09-25T20:29:42 < emeb> Bresenham's makes nice circles too
2013-09-25T20:29:42 < karlp> jpa-: no more or less stupid than the f103/107 that people steal talk about all the time
2013-09-25T20:29:50 < jpa-> karlp: true
2013-09-25T20:30:00 < trepidaciousMBR> I just mashed together some bits of adafruit arduino code and someone else's mbed stuff for my screen, but it is only a tiny screen so not much to do
2013-09-25T20:30:08 < jpa-> if someone knows of a nice graphics library that offers "pixels on demand" style rendering, please tell
2013-09-25T20:30:10 < trepidaciousMBR> the hard thing is finding half-decent bitmap fonts
2013-09-25T20:30:18 < jpa-> or line-by-line is fine too
2013-09-25T20:30:35 < jpa-> trepidaciousMBR: https://code.google.com/p/mcufont/  :P
2013-09-25T20:30:37 < trepidaciousMBR> jpa-: So you render as it displays?
2013-09-25T20:30:44 < jpa-> i would want to, yeah
2013-09-25T20:31:05 < jpa-> but haven't found a library that would do the rendering
2013-09-25T20:31:14 < karlp> emeb: you don't go back and update the availability sections down the road? ;)
2013-09-25T20:31:27 < trepidaciousMBR> jpa-: Ah cool thanks - I just ended up retouching a font rendered in java, because I couldn't find any TTF fonts that rendered reasonably at the size I wanted
2013-09-25T20:32:00 < emeb> karlp: sometimes I do. I updated part of that site last night with new stuff (next level up)
2013-09-25T20:32:11 < trepidaciousMBR> jpa-: Your library looks much better, I'll have to try it :)
2013-09-25T20:32:17 < jpa-> trepidaciousMBR: hmm.. must have been a very small size or else you have had hinting turned off
2013-09-25T20:32:55 < emeb> didn't fix that one tho. Here's the disty pg: http://www.analoguehaven.com/synthesistechnology/e355/
2013-09-25T20:33:12 < jpa-> had to write that library because basically nothing supported 130 pixel high fonts.. and they would have taken a lot of flash anyway
2013-09-25T20:33:19 < trepidaciousMBR> jpa-: TBH I think hinting is basically a myth :) I just remember years of fonts never looking right on anything, then the final blessed point where everyone gave up and just started ignoring hints and rendering to subpixels, and now we have high dpi displays where it matters even less, yay :)
2013-09-25T20:33:47 < trepidaciousMBR> jpa-: Mine are just 16px high, on a 128x64 display
2013-09-25T20:33:50 < jpa-> trepidaciousMBR: yeah; but hinting was (and is) important if you don't have subpixel rendering
2013-09-25T20:34:43 < trepidaciousMBR> jpa-: Yup, it just never works for me. I got one that looked okayish, but still not right. It's probably Java messing it up, but I never had much luck with any other system either :) What do you use for rendering fonts, freetype?
2013-09-25T20:35:24 < jpa-> freetype yeah for ttfs.. also bdf is supported directly, X11 comes with some nice public domain bitmap fonts in bdf format
2013-09-25T20:35:54 < trepidaciousMBR> jpa-: I'm ok now anyway, Verdana at 16 points, edited in gimp, looks fine :)
2013-09-25T20:36:05 < jpa-> :)
2013-09-25T20:36:20 < trepidaciousMBR> I'll defn. use yours if I ever need anything else though ;)

2013-09-25T21:44:56 < Thorn> although with small sales it's the only way
2013-09-25T21:48:17 < emeb> Thorn: Cost breakdown is like this: ~40% overhead for the distributor, so $150 for wholesale price
2013-09-25T21:49:51 < emeb> Of that about $60 is PCB, parts & assy. Another $20 for front panel, knobs, packaging. so about $70 margin out of which my client and I get paid.
2013-09-25T21:50:40 <+Steffanx> Oh, i expected the panel to be more expensive than the pcb.
2013-09-25T21:51:23 < emeb> Nah. Panels are Metalphoto - very reasonably priced when you buy 100s

2013-09-25T22:21:40 < gxti> noted
2013-09-25T22:21:48 < gxti> although i doubt i'll ever sell 100 of my crap
2013-09-25T22:24:26 < Laurenceb__> so sell dataloggers
2013-09-25T22:24:35 < Laurenceb__> theres always a need for moar dataloggers
2013-09-25T22:28:20 < gxti> i'd have to increase the price for anyone to take it seriously :P
2013-09-25T22:28:29 < gxti> and pay for boring shit like EMC testing
2013-09-25T22:28:37 < Laurenceb__> yup
2013-09-25T22:28:50 < gxti> and pay someone else to assemble the shit because i have better things to do (not really)
2013-09-25T22:29:05  * Laurenceb__ charges £6k/logger
2013-09-25T22:29:46 < Laurenceb__> i cheated EMC - had the stm32 in sleep almost all the time
2013-09-25T22:29:52 < gxti> honestly i think i could turn it (a gps ntp server) into a legit product but it's a lot of work and i'm lazy
2013-09-25T22:30:27 < Thorn> emeb: I see thanks. looks like it's more profitable to be a distributor than a designer
2013-09-25T22:30:40 < gxti> i don't think EMC would be too hard because it's 4 layers but i have no way of knowing
2013-09-25T22:31:02 < gxti> also using prefab smps module + linear regulator, and it's in a metal box
2013-09-25T22:31:07 < emeb> Thorn: Yeah - that disty is pretty much rolling in it.
2013-09-25T22:31:15 < gxti> so probably i'll have to add some filtering to smps and done? who knows
2013-09-25T22:31:39 < emeb> On the upside - he pays up front before the modules are built so that simplifies the financing for the mfgs.
2013-09-25T22:33:15 < Laurenceb__> http://i.imgur.com/O7tcd50.png
2013-09-25T22:33:39 < Laurenceb__> thats running 100% of the time at 72Mhz
2013-09-25T22:33:49 < Laurenceb__> big spike at third harmonic
2013-09-25T22:34:05 < Laurenceb__> a few dB over the limit for CE
2013-09-25T22:34:12 < gxti> my thing doesn't and can't sleep so i'm sure fixes will be required D:
2013-09-25T22:34:17 < Laurenceb__> but sleeping fixes it
2013-09-25T22:34:30 < Laurenceb__> and its actually legit
2013-09-25T22:34:32 < gxti> although actually i should revisit that
2013-09-25T22:34:44 < gxti> but it has to have a timer running at 70mhz full time so maybe not that helpful
2013-09-25T22:34:45 < Laurenceb__> you are allowed to do certain forms of averaging

2013-09-25T22:35:23 <+Steffanx> lol Laurenceb__ . So sleep to pass CE and it's good to change it afterwards :P
2013-09-25T22:35:35 < Laurenceb__> yup
2013-09-25T22:35:38 < gxti> does your logger have gps or is it just time-correlated against the other receiver? i remember you bitching about that
2013-09-25T22:36:00 < Laurenceb__> theres a bluetooth receiver
2013-09-25T22:36:11 < Laurenceb__> so time sync isnt perfect
2013-09-25T22:36:24 < Laurenceb__> its annoying when the ambulance is accelerating - you get lag
2013-09-25T22:36:36 < Laurenceb__> and it all gets messy with certain forms of analysis
2013-09-25T22:36:37 < gxti> wondering if EMC is any more difficult with a gps receiver, probably not
2013-09-25T22:37:09 < Laurenceb__> i didnt test the gps - if was an off the shelf bluetooth thingy
2013-09-25T22:37:14 < gxti> easier than bluetooth anyway

2013-09-25T22:55:51 < bighead123> Hello
2013-09-25T22:55:55 < bighead123> Trouble connecting 176x220 TFT LCD to STM32F4 Discovery.
2013-09-25T22:56:06 < bighead123> Working already 4days with no result
2013-09-25T22:57:11 < bighead123> Can't understand how 8080 LCD interface works in general
2013-09-25T22:59:21 < bighead123> This two functions are right? https://www.dropbox.com/s/am3wnyladewny6v/code.c
2013-09-25T23:02:33 < emeb> got a link to the LCD datasheet?
2013-09-25T23:03:55 < Thorn> you can test those functions with a multimeter or even a led+resistor if that's all you have
2013-09-25T23:04:03 < Thorn> just call them once and loop
2013-09-25T23:04:48 < Thorn> also they're wrong
2013-09-25T23:05:02 < bighead123> Thorn: Why they are wrong?
2013-09-25T23:05:03 < Thorn> GPIOD->ODR |= (0 << 0);  doesn't change any bits
2013-09-25T23:05:31 < Thorn> definitely doesn't set bit 0 to 0
2013-09-25T23:05:49 < bighead123> Thorn: It would not set 0 in portD pin0?
2013-09-25T23:05:59 < gxti> bighead123: do you know what << means?
2013-09-25T23:06:30 < Thorn> a & 1 = a; a & 0 = 0; a | 1 = 1; a | 0 = a
2013-09-25T23:06:45 < gxti> that's just going to make his head asplode, Thorn
2013-09-25T23:06:59 < Thorn> sorry for the mess
2013-09-25T23:07:25 < gxti> bighead123: << is a left shift operator. it takes the number on the left, and shifts it over by some number of bits (on the right)
2013-09-25T23:07:25 < GargantuaSauce> use BSRRL to set 1s and BSRRH to set 0s
2013-09-25T23:07:31 < GargantuaSauce> no |= &= NECESSARY
2013-09-25T23:07:38 < bighead123> gxti: no, as I know this combination GPIOD->ODR |= (1 << 7);  would set 1 in portDs pin7, it isn't?
2013-09-25T23:07:40 < gxti> bighead123: if you start with 0 and shift it as many times as you like it's still 0
2013-09-25T23:08:21 < bighead123> gxti: and how I can write 0 to portD pin0?
2013-09-25T23:09:01 < gxti> using BSRR like GargantuaSauce said is the easiest way, it lets you set and clear bits without needing |= or &=
2013-09-25T23:09:15 < gxti> but just for educational purposes i will also tell you how to fix the code you have now
2013-09-25T23:09:24 < gxti> the opposite of "foo |= bar" is "foo &= ~bar"
2013-09-25T23:09:51 < gxti> so you could do "GPIOD->ODR &= ~(1 << 7)" to turn 7 off
2013-09-25T23:10:14 < bighead123> gxti: Thank you, I'll try that now
2013-09-25T23:10:40 < gxti> (1<<7) is a number where just the bit corresponding to position 7 is set
2013-09-25T23:10:54 < gxti> when you use it with |= it means keep all the other bits the same, and turn that one bit on
2013-09-25T23:11:07 < gxti> any bit that is zero is unaffected, which is why your way does nothing
2013-09-25T23:11:32 < gxti> also because 0 << 7 is 0
2013-09-25T23:11:36 < gxti> which isn't very helpful...
2013-09-25T23:11:55 < bighead123> gxti: this symbol & would keep other bits unaffected too?
2013-09-25T23:12:21 < GargantuaSauce> we are missing some basic theory here
2013-09-25T23:12:40 < gxti> |= turns on all bits from the number on the right, &= turns OFF all bits that are off on the number on the right. so you're turning 0b100000 into 0b01111111 with the ~, then it can turn off just that one bit (#7)
2013-09-25T23:13:23 < gxti> but yeah, this is basic boolean logic and bitwise arithmetic
2013-09-25T23:13:42 < gxti> you should learn about it.

2013-09-25T23:20:02 < Thorn> The regulator ON/internal reset ON mode is always enabled on LQFP64 and LQFP100 package. On LQFP144 package, this mode is activated by setting PDR_ON to VDD.

2013-09-25T23:26:05 < GargantuaSauce> this code is garbage but works
2013-09-25T23:26:21 < GargantuaSauce> (for ssd1289)
2013-09-25T23:26:31 <+Steffanx> UltraSauce :)
2013-09-25T23:26:48 < Thorn> aren't multiple nops folded together by the core?
2013-09-25T23:27:10 < Thorn> consecutive nops
2013-09-25T23:27:26 < Thorn> so nop;nop;nop isn't a 3-cycle delay
2013-09-25T23:27:36 < GargantuaSauce> no idea, i dont think a single one worked though
2013-09-25T23:27:49 < bighead123> GargantuaSauce: Thank you, I'll rewrite logic from there, except commands. Most likely logic would be the same, this is 16 bit parallel 8080 port right?
2013-09-25T23:27:55 < GargantuaSauce> yes
2013-09-25T23:32:28 < GargantuaSauce> use a real delay instead of nops
2013-09-25T23:33:04 < bighead123> _controlGPIO->BSRRL = PIN_WR; This command sets PIN_WR to 0 or to 1?
2013-09-25T23:33:34 < GargantuaSauce> BSRRL sets 1, BSRRH sets 0
2013-09-25T23:34:49 < bighead123> GargantuaSauce: Here is also #define PIN_WR 0x0004 i.e. BSRRL register would get 0x0004 combination of 0s and 1s?
2013-09-25T23:36:00 < GargantuaSauce> when you write any 1s to BSRRL it sets those pins to 1. when you write any 1s to BSRRH it sets those pins to 0
2013-09-25T23:36:50 < GargantuaSauce> so writing 4 to bsrrl sets the third bit in the gpio to 1 and leaves the others untouched
2013-09-25T23:37:38 < GargantuaSauce> BSRRL = x is equivalent to ODR |= x.   BSRRH = x is equivalent to ODR &= ~x
2013-09-25T23:38:01 < GargantuaSauce> just avoids the extra instructions reading from odr and doing the bitwise or/and
2013-09-25T23:40:14 < GargantuaSauce> (and is atomic and thus less susceptible to fuckups if an interrupt messes with the gpio in the middle)
2013-09-25T23:47:16 < bighead123> GargantuaSauce: for S6D0128 and  ssd1289 commands and register addresses are same?
2013-09-25T23:47:37 < GargantuaSauce> i have no idea
2013-09-25T23:47:43 < GargantuaSauce> probably not but maybe

2013-09-26T00:06:38 < bighead123> and of course write 16 bit data to port at first
2013-09-26T00:06:48 < bighead123> *writing
2013-09-26T00:07:04 < GargantuaSauce> as i said, you need to delay between writing to the data port and setting wr to 0
2013-09-26T00:09:25 < bighead123> GargantuaSauce: added but still not works, everything else is correct?
2013-09-26T00:10:13 < GargantuaSauce> set rd and rs before that new delay also
2013-09-26T00:10:25 < GargantuaSauce> so that everything has settled by the time you strobe the write line
2013-09-26T00:11:38 < GargantuaSauce> and leave rd at 1 always except for when you actually want to read something...
2013-09-26T00:13:27 < qyx_> Thorn: whats bad with it?

2013-09-26T00:32:47 < Thorn> does it even run? blink a led? do you have a scope / logic analyzer to loog at the signals?
2013-09-26T00:33:06 < GargantuaSauce> cmd/data look fine now, it's probably the commands
2013-09-26T00:33:22 < GargantuaSauce> i had a lot of trouble building an initialization sequence from the datasheet and ended up stealing it from somewhere
2013-09-26T00:33:40 < GargantuaSauce> but yes as Thorn says you should probably do some sanity checks
2013-09-26T00:36:15 < bighead123> I have nothing like logic analyzer or oscilloscope. just some parts and demo boards. Screen blinks at start at least for 2 seconds but remains white in end

2013-09-26T02:20:05 < gxti> anyone implemented native SDIO without the SDIO peripheral before?
2013-09-26T02:20:21 < gxti> wondering if it's worth the trouble since i'm starting from scratch anyway

2013-09-26T02:34:50 < gxti> DMA bitbanging :D
2013-09-26T02:35:07 < emeb> sounds... intense
2013-09-26T02:35:08 < gxti> probably not though, i don't need throughput so i might as well do spi since there are lots more examples of it
2013-09-26T02:35:13 < Fornaxian> SDIO is for SD cards?
2013-09-26T02:35:19 < emeb> ya
2013-09-26T02:35:26 < Fornaxian> aahh.
2013-09-26T02:35:26 < emeb> SPI MMC/SD is easy
2013-09-26T02:35:37 < Fornaxian> have done it on AVR but not on ARM yet..
2013-09-26T02:36:04 < gxti> chibios comes with fatfs bindings, it's pretty much plug-and-play. but i dropped chibios, so now i get to write some stuff
2013-09-26T02:36:17 < gxti> keeping fatfs though of course
2013-09-26T02:36:21 < emeb> natch
2013-09-26T02:36:56 < emeb> the main thing that I found to be tricky is some of the startup sequences to test for a valid card.
2013-09-26T02:37:05 < emeb> timing gets a little funky.
2013-09-26T02:38:49 < emeb> but I think fatfs handles most of that now.

2013-09-26T05:53:20 < dongs> yeah, but it doesnt matter its just port name
2013-09-26T05:53:28 < dongs> in code its just assign ts_clk = refclk27;
2013-09-26T05:53:38 < emeb_mac> did you create a .ucf to assign those signals to pins?

2013-09-26T06:20:21 < emeb_mac> do you have to put quotes around the location pad value?
2013-09-26T06:20:40 < emeb_mac> on my vqf100 packages the locations look like LOC = "P8";

2013-09-26T06:25:30 < dongs> which is ok since im not using htem
2013-09-26T06:25:54 < emeb_mac> pretty basic
2013-09-26T06:26:28 < dongs> There are 6 loadless signals in this design. This design will cause Bitgen to issue DRC warnings.
2013-09-26T06:27:14 < dongs> thats the only warnings (well, with some other useless ones).
2013-09-26T06:27:21 < dongs> but nothign that would make it not work anyway.

2013-09-26T10:11:02 < dongs> zyp, i have your invoice for all parts minus connectors
2013-09-26T10:18:49 < zyp> :)
2013-09-26T10:22:54 < zyp> looks good
2013-09-26T10:23:05 < zyp> so, should I just pay this, or what?

2013-09-26T10:42:46 < dongs> ya
2013-09-26T10:43:02 < dongs> oh, and minus usb - but we got 500 of them on hand
2013-09-26T10:43:09 < dongs> will add to pcba inv or something
2013-09-26T10:43:32 < dongs> usb is 0.40/ea
2013-09-26T10:44:52 < dongs> for connectors... you should be able to add htem to cart on u.s. site without logging in, hten complete checkout in USD and set shipping to pcba place address. it'll cost extra 30bucks in shipping but should work.
2013-09-26T10:45:31 < dongs> billing address - yours , shipping address - pcba.
2013-09-26T10:45:52 < dongs> china has 4pin stuff for cheap nbut not enough stock.. like 2c/ea butthey only got like 400

2013-09-26T13:44:25 < zyp> reminds me of altium's footprint wizard
2013-09-26T13:44:45 < zyp> it tends to ask about measurements that's not listed in the datasheet
2013-09-26T13:47:51 < Thorn> ok so this "factory since 2003" makes two almost identical displays, one ("innolux compatible") needs 3 supply voltages, the other 1 (not including baclkight). where is the catch
2013-09-26T13:51:45 < dongs> zyp: does it? it asks all the normal stuff that usually IS in datasheets
2013-09-26T13:51:58 < Thorn> http://www.buy-display.com/download/manual/ER-TFT070-2_Manual.pdf  http://www.buy-display.com/download/manual/ER-TFT070-4_Manual.pdf
2013-09-26T13:52:08 < dongs> so that's the -2 or -4 part
2013-09-26T13:55:44 < zyp> dunno, I've ended up drawing the footprints by hand, because that's just as fast
2013-09-26T13:56:01 < zyp> because of the paste array-function
2013-09-26T13:56:02 < dongs> wizard was ok for simple symmetric stuff
2013-09-26T13:56:11 < dongs> i.e. qfp, qfn, bga, etc.
2013-09-26T13:56:56 < zyp> just draw one pad with correct measurements, copy and paste array with correct pitch, then just place the arrays correctly
2013-09-26T13:57:10 < zyp> then draw up some sensible silk
2013-09-26T14:01:34 < dongs> then draw a dick on silk
2013-09-26T14:01:59 < dongs> Laurenceb probably has a dick under every QFP
2013-09-26T14:03:10 < Thorn> he did but he put them on the wrong side once, now he doesn't
2013-09-26T14:05:03 < Thorn> those displays are different: one is slightly brighter (250 vs. 200), the other has slightly better viewing angles
2013-09-26T14:09:37 < zyp> altium's pinswapping function is pretty neat
2013-09-26T14:10:15 < dongs> yea... i need to really stop using this dicktrace shit
2013-09-26T14:10:56 < karlp> zyp: what does that do?
2013-09-26T14:11:41 < dongs> huh
2013-09-26T14:11:45 < dongs> what does pinswapping do?
2013-09-26T14:13:02 < zyp> karlp, first you make swapgroups directly in pcb view, then it has some nice highlighting of which pins can be swapped
2013-09-26T14:14:32 < zyp> currently pinswapping bga sram lines, so I route the lines over to the sram, then I click the via I want to connect to and the trace I want to connect to that via, and then it gets swapped so that trace can connect to that via
2013-09-26T14:15:06 < dongs> is that some avr32 shit
2013-09-26T14:15:25 < zyp> yep, still same shit
2013-09-26T14:23:20 < dongs> i just acquired latest altium from soviet russia
2013-09-26T14:23:23 < dongs> few days ago
2013-09-26T14:24:23 < karlp> you define swappable pins in the package right? and at layout time you can choose to do some swapping?
2013-09-26T14:24:42 < dongs> from what I understand you can assign that at layout time?
2013-09-26T14:24:48 < dongs> or maybe in symbol?
2013-09-26T14:24:52 < jpa-> it's a bit cumbersome if your have to give them in package/symbol
2013-09-26T14:27:05 < zyp> you can define it at layout time
2013-09-26T14:27:11 < zyp> that's what I did
2013-09-26T14:27:47 < zyp> defined one group for addr pins, one group for upper data lanes and one group for lower data lanes
2013-09-26T14:28:45 < dongs> how come you can swap sram
2013-09-26T14:28:58 < dongs> isnt that usually controller specific
2013-09-26T14:29:00 < dongs> like fsmc
2013-09-26T14:29:21 < jpa-> the sram chip doesn't care in which order the bits are
2013-09-26T14:29:25 < jpa-> it's just data
2013-09-26T14:29:46 < dongs> heh
2013-09-26T14:29:59 < dongs> well, i supose so
2013-09-26T14:30:16 < zyp> yep, only thing that matters are byte groups, because of byte enable lanes
2013-09-26T14:30:59 < zyp> on dram addr lines can't be swapped since they are used for commands, but on sram it doesn't matter
2013-09-26T14:32:16 < jpa-> i guess on psram it would matter, though?
2013-09-26T14:32:40 < dongie> zyp, pcb goes in tomororw, any changes or is 1.1 shit you sent ifnal?
2013-09-26T14:33:07 < zyp> it's final
2013-09-26T14:33:22 < dongie> btw thanks for picking a LDO that wasnt weird shit
2013-09-26T14:33:49 < zyp> I'm not doing that mistake twice :p

2013-09-26T21:52:58 < emeb> they're unlikely to go after small users
2013-09-26T21:53:36 < Thorn> there's prior art in amateur magazines
2013-09-26T21:53:39 < emeb> and there are a number of alternative ways to control LEDs that don't infringe if you care.
2013-09-26T21:53:51 < emeb> Prior art means absolutely zilch these days.
2013-09-26T21:54:31 < emeb> If you get sued for infringement it's a minimum $1M to defend yourself, even if you bring in prior art, expired patents and a note from your mom.
2013-09-26T21:55:21 <+Steffanx> Sounds like emeb has experience...
2013-09-26T21:55:22 < gnomad> IIRC, the patent only applies when the RGB element is used as a "pixel"
2013-09-26T21:55:42  * emeb has his name on a lot of patents.
2013-09-26T21:56:20 < emeb> and has spent a lot of time talking to IP attorneys and folks in the field.
2013-09-26T22:00:32 < Thorn> what are alternative metods to control LEDs?
2013-09-26T22:01:04 < emeb> There are chips out there that control the forward current instead of PWMing.
2013-09-26T22:02:48 < Thorn> that sounds even more likely to be patented
2013-09-26T22:04:16 < emeb> Possibly.
2013-09-26T22:04:56 < emeb> Depending on how the Philips patent claims are written there may be simple ways around it too.
2013-09-26T22:05:33 < emeb> Since it looks like they're mainly using it to beat up on some spinoff company.
2013-09-26T22:07:49 < emeb> eg - http://www.electronicsweekly.com/news/design/embedded-systems/microcontrollers-address-color-kinetics-led-lighting-2013-03/

2013-09-26T22:10:02 < emeb> I've got a patent on a bit-reversed counting approach that achieves the same result as PWM while driving the fundamental frequency higher and making filtering easy. Stuff like that is a good way to work around.
2013-09-26T22:10:46 <+Steffanx> I totally wouldn't care if i used something that turned out to be that :P
2013-09-26T22:12:27 < emeb> It's a risk tradeoff - what do you have to lose if you're sued for infringement and what are the remedies.
2013-09-26T22:12:51 <+Steffanx> What is the chance you figure out i used that same thing for my product?
2013-09-26T22:13:52 < Thorn> A patent has been applied for by Infineon.
2013-09-26T22:18:06 < jpa-> emeb: what? you have patented that? i've been using it since ages :D

2013-09-26T22:18:38 < Thorn> jpa-: you shouldn't have said that
2013-09-26T22:18:39 < jpa-> it is, indeed
2013-09-26T22:18:57 < emeb> I'm surprised that the current holder has kept it paid up.
2013-09-26T22:19:10 < jpa-> Thorn: you think emeb is coming to sue me over my binary clock? ;)
2013-09-26T22:19:12 < emeb> I didn't think it was particularly special when I did it.
2013-09-26T22:19:37 <+Steffanx> And still you patented it ..

2013-09-26T22:19:53 < karlp> he clearly worked somewhere that valued patents
2013-09-26T22:19:59 < emeb> Yeah - the company I worked for was building up the "war chest".
2013-09-26T22:20:32 < jpa-> i have one ridiculous patent application also.. no idea if it will pass
2013-09-26T22:20:50 <+Steffanx> What jpa-? And you complain about this ugfx license?

2013-09-26T22:23:37 < emeb> there's a  much simpler way to do this too - just use an accumulator and bring out the carry bit.

2013-09-26T22:27:26 < Laurenceb__> clever
2013-09-26T22:28:21 < emeb> as I said, you can do the same thing by driving the data into an accumulator and picking off the carry output.
2013-09-26T22:28:55 < emeb> kinda like poor-mans sigma-delta.
2013-09-26T22:29:49 < Thorn> is it monotonic?
2013-09-26T22:29:57 < emeb> yep
2013-09-26T22:30:15 < jpa-> (except if the hardware is non-linear, like slowly rising FET gates)
2013-09-26T22:30:58 < emeb> and the LPF to reconstruct can be simpler since there is less low frequency content.
2013-09-26T22:31:48 < emeb> jpa-: good point! slow switching can mess it up badly if the rise/fall times approach the clock rate.

2013-09-27T00:54:42 < GargantuaSauce> i have a somewhat general software design question
2013-09-27T00:55:56 < GargantuaSauce> say you've designed a nontrivial state machine with state transitions triggered both by other parts of the software and hardware interrupts
2013-09-27T00:56:35 < GargantuaSauce> would the abstraction of that state machine make its way into your software or would you leave it 'on paper' and just implement it in a more direct fashion
2013-09-27T00:57:45 < GargantuaSauce> practical context is i am implementing the link-layer of a radio communication protocol
2013-09-27T00:59:38 < GargantuaSauce> i guess another way to put it is how explicit would the existence of the states and transitions be in your code
2013-09-27T01:02:15 < Thorn> I would expect an explicit state machine to be much easier to maintain (especially if it's nontrivial)
2013-09-27T01:02:28 -!- CRF_Peter [~Peter@81-237-198-30-no92.tbcn.telia.com] has joined ##stm32
2013-09-27T01:02:58 < Thorn> I like to have a separate rtos tasks and a message queue for all external events
2013-09-27T01:03:22 < Thorn> there's an enum for states and a tagged union type for events
2013-09-27T01:06:00 < Thorn> and if you ebd up several state variables, better make the fsm hierarchical if possible
2013-09-27T01:06:17 < Thorn> *end up with several
2013-09-27T01:06:32 < GargantuaSauce> yeah that sounds pretty sane
2013-09-27T01:06:47 < GargantuaSauce> will definitely be doing that for different protocol layers
2013-09-27T01:20:40 < gxti> nano printf or whatever has an interesting idea of %x... trying to debug some SD stuff and it's printing 'i' instead of 'f'
2013-09-27T01:21:28 < Thorn> I had similar paranormal crap with some other printf implementation found on the net
2013-09-27T01:21:38 < gxti> %X seems work normally
2013-09-27T01:21:54 < Thorn> it randomly switched to capital letters
2013-09-27T01:23:23 < gxti> the good news is that stuff is working.
2013-09-27T01:23:29 < Thorn> i instead of f sounds like memory corruption in the last element of the array containing hex digits
2013-09-27T01:24:08 < gxti> lots of stupid mistakes that all took me way too long to track down
2013-09-27T01:26:31 < bighead123> still no result :(

2013-09-27T01:29:16 < qyx_> 4.4e vs 7.3e
2013-09-27T01:29:34 < gxti> qyx_: dk/mouser/farnell all mark it up asstons
2013-09-27T01:29:44 < gxti> qyx_: futureelectronics has them cheap too
2013-09-27T01:29:56 < gxti> or verical if you need dozens
2013-09-27T01:29:57 < qyx_> i'll check
2013-09-27T01:30:10 < gxti> they have good prices but exorbitant handling charges so it's only worthwhile for medium qtys
2013-09-27T01:30:55 < emeb> did someone here have a set of udev rules for the BMP?
2013-09-27T01:31:19 < gxti> emeb: yep
2013-09-27T01:31:26 < gxti> ATTRS{interface}=="Black Magic GDB Server", SYMLINK+="bmp%n"
2013-09-27T01:31:26 < gxti> ATTRS{interface}=="Black Magic UART Port", SYMLINK+="ttyBMP%n"
2013-09-27T01:31:46 < gxti> gives you /dev/bmp0 and /dev/ttyBMP1
2013-09-27T01:32:17 < emeb> thx
2013-09-27T01:34:09 < gxti> unfortunately udev makes it annoying to do something like give unique names by serial number, because there are two devices
2013-09-27T01:34:38 < gxti> you can match attributes in the top-level thing, and you can match attributes in ONE parent in the hierarchy, but not two different parents (e.g. the name of the endpoint, plus the serial number from the device itself)
2013-09-27T01:35:04 < gxti> serial is 2 levels up and endpoint is 1 level up, and the top object has no identifying information :|
2013-09-27T01:36:52 < emeb> yeah udev is still mostly a mystery to me
2013-09-27T01:37:23 < emeb> I'm guessing one needs a newer version of the firmware for this to work - my BMP still rings up as ttyACM0/1
2013-09-27T01:37:39 < gxti> hmm, something is definitely getting corrupted. if i printf at the top of main_thread it still prints ii instead of ff, if i printf before the thread is started i get nothing but the later stuff is corrupted differently
2013-09-27T01:37:52 < emeb> old firmware may not have the "Black Magic xxx" identifiers
2013-09-27T01:38:27 < gxti> emeb: udevadm info --attribute-walk /sys/class/tty/ttyACM0
2013-09-27T01:38:54 < gxti> that should take a lot of the mystery out. you can match anything from the first section, and anything from ONE of the sections below.
2013-09-27T01:40:46 < emeb> ok
2013-09-27T01:41:15 < gxti> gdb compare-sections says ".text MIS-MATCHED!", woo.
2013-09-27T01:41:17 < emeb> had to add a --path= but it dumped a bunch of stuff and there was a "BMP..." attribute in there.
2013-09-27T01:41:47 < gxti> can bmp actually readback flash or just compare?
2013-09-27T01:41:52 < zyp> OS X makes /dev/cu.usbmodemE2C8A901 and /dev/cu.usbmodemE2C8A903 without any special magic
2013-09-27T01:42:02 < zyp> gxti, both
2013-09-27T01:42:36 < zyp> «compare-sections» will have it do the comparison on the BMP itself and just pass the result back
2013-09-27T01:43:07 < zyp> but remember that since the flash is memory mapped, reading back the flash is no different from reading any other kind of memory
2013-09-27T01:43:23 < zyp> so you can of course read it back
2013-09-27T01:43:28 < gxti> sure, but all i know is something in a 10K text section is wrong
2013-09-27T01:43:45 < gxti> would be nice if i could identify the exact location
2013-09-27T01:43:47 < emeb> gxti: is there some extra magic required in the .rules file? looks like they didn't get applied.
2013-09-27T01:44:57 < gxti> emeb: name the file 00-blackmagic.rules (has to end in .rules anyway), run udevadm control --reload, replug device
2013-09-27T01:45:45 < zyp> I recommend putting the usb serial into the symlink name
2013-09-27T01:46:08 < gxti> again, udev makes that annoying due to an arbitrary and obnoxious limitation
2013-09-27T01:46:11 < zyp> http://paste.jvnv.net/view/HCLYH <- then port my script to linux
2013-09-27T01:46:31 < zyp> then you get the nice «target bmp» command
2013-09-27T01:47:18 < gxti> although actually using the serial in the link name might be possible
2013-09-27T01:47:21 < gxti> not sure.
2013-09-27T01:55:10 < bighead123> SO GREAT :))) I found another error, IM0 is connected as 8bit mode, I was at first writing for 8 bit mode and forgot changing.
2013-09-27T01:55:16 < bighead123> Now would resolder
2013-09-27T01:56:01 < emeb> meh

2013-09-27T03:38:47 < bighead123> zyp: amstan: I just want at first to build any video player
2013-09-27T03:39:28 < amstan> bighead123: i recomend this: http://dx.com/p/mini-stm32-stm32f103rbt6-development-board-w-2-8-tft-lcd-touch-screen-157301
2013-09-27T03:39:46 < bighead123> zyp: I have this datasheet but still not got it working
2013-09-27T03:39:53 < amstan> you just need some kind of dac
2013-09-27T03:40:35 < amstan> then you get this guy's code: http://www.youtube.com/watch?v=ObA3Ua0H53U
2013-09-27T03:40:40 < amstan> https://github.com/ornotermes/ministm32_v3
2013-09-27T03:41:16 < zyp> bighead123, how did you set IM0-3?
2013-09-27T03:41:23 < zyp> (the mode pins)
2013-09-27T03:41:59 < zyp> also, your line 24 is obviously wrong
2013-09-27T03:42:01 < zyp> GPIOD->ODR &= (0 << 4);            //RESET = 0
2013-09-27T03:42:17 -!- R0b0t1` [~dev@unaffiliated/r0b0t1] has quit [Ping timeout: 240 seconds]
2013-09-27T03:42:25 < zyp> and please not use ODR like that, use BSRR
2013-09-27T03:42:47 < bighead123> zyp: here is only IM0 output on LCD port and I have connected it to 0
2013-09-27T03:42:51 < bighead123> i.e. GND
2013-09-27T03:43:16 < bighead123> zyp: this could be reason? GPIOD->ODR &= (0 << 4);            //RESET = 0
2013-09-27T03:43:51 < zyp> well, it will not work, at least
2013-09-27T03:43:55 < zyp> but probably not
2013-09-27T03:44:08 < zyp> either way, you'd want to fix it
2013-09-27T03:44:57 < bighead123> zyp: now I'll check if RESET is 1 with multimeter
2013-09-27T03:45:19 < zyp> so anyway, what kind of interface is ID1-3 set for then? I mean, what kind of interface are you trying to use?
2013-09-27T03:45:38 < zyp> because this stuff supports both 68-style and 80-style
2013-09-27T03:45:51 < zyp> and getting that wrong is an obvious reason for it not working
2013-09-27T03:46:17 < bighead123> zyp: did you mean 0x03 register setting?
2013-09-27T03:46:33 < zyp> no, I mean the pins IM0-3 like documented on page 20 in the datasheet
2013-09-27T03:47:02 < zyp> the controller have those pins, so if they are not exposed through your breakout, they are already set to something somewhere
2013-09-27T03:47:20 < zyp> and if you don't know what, it's no wonder you don't get it to work
2013-09-27T03:47:47 < zyp> how many data lines do you have?
2013-09-27T03:48:18 < bighead123> zyp: I am using 16 lines and IM0 connected to GND
2013-09-27T03:48:19 < bighead123> https://www.dropbox.com/s/ou6k6s1y8tb438p/020F.7z
2013-09-27T03:48:26 < zyp> right, then that much is correct
2013-09-27T03:48:29 < bighead123> this is LCD datasheet
2013-09-27T03:48:38 < zyp> supposing that IM2 and IM3 are connected low somewhere
2013-09-27T03:48:47 < zyp> ok, hang on, I'll look
2013-09-27T03:48:47 < bighead123> zyp: there is no IM123 pins on LCD connector
2013-09-27T03:49:08 < zyp> 02:47:02 < zyp> the controller have those pins, so if they are not exposed through your breakout, they are already set to something somewhere
2013-09-27T03:50:32 < zyp> right, your datasheet says 8080 style, so IM1 is wired high and IM2-3 is wired low
2013-09-27T03:55:25 < bighead123> zyp: now checking connections again
2013-09-27T03:55:43 < zyp> hmm, can't see anything obviously wrong besides the RESET stuff
2013-09-27T03:56:00 < zyp> and I don't think the RESET stuff is the problem
2013-09-27T04:01:45 < bighead123> zyp: everything is absolutely correctly with connections
2013-09-27T04:02:46 < bighead123> zyp: the only reason here could be commands in LCD_Initialise
2013-09-27T04:02:49 < zyp> which stm32 variant are you using?
2013-09-27T04:03:07 < bighead123> zyp: STM32F4 Discovery
2013-09-27T04:04:51 < zyp> hmm
2013-09-27T04:05:28 < zyp> your delay function doesn't really make sense
2013-09-27T04:05:41 < zyp> it's certainly not milliseconds, at least :p
2013-09-27T04:06:00 < zyp> have you actually scoped the signals to see whether the timing is sane?
2013-09-27T04:06:41 < zyp> hmm
2013-09-27T04:07:00 < bighead123> zyp: I know, but it makes actually long delay, here it doesn't means how long it would be, right?
2013-09-27T04:07:20 < bighead123> zyp: it just must not be less than specified
2013-09-27T04:07:23 < zyp> true, as long as it doesn't get too short
2013-09-27T04:08:27 < zyp> gpio settings also looks sane, and you didn't forget the rcc enables
2013-09-27T04:08:55 < zyp> so it doesn't appear to be anything wrong there either
2013-09-27T04:09:14 < bighead123> zyp: what did you mean "RCC enables"?
2013-09-27T04:09:26 < zyp> RCC->AHB1ENR |= RCC_AHB1ENR_GPIOEEN;
2013-09-27T04:10:06 < bighead123> zyp: yes I wrote that
2013-09-27T04:11:53 < zyp> anyway, what I'd do is try to read some data back from the display
2013-09-27T04:12:04 < zyp> I'd start by trying to read the device code
2013-09-27T04:12:14 < bighead123> zyp: GREAT IDEA!
2013-09-27T04:12:16 < zyp> as described on page 38 in the datasheet
2013-09-27T04:12:36 < zyp> if that doesn't work, then you're certainly doing something wrong with the interfacing
2013-09-27T04:12:48 < bighead123> right!
2013-09-27T04:13:00 < zyp> and if it works, then I'd try reading back a register before and after changing it, to check that it really changed
2013-09-27T04:13:17 < zyp> if that also works, then it means that both reads and writes are fine, so the problem must be in the commands.
2013-09-27T04:14:05 < bighead123> zyp: Do you know which of LCD registers are necessary to just display color? I want to remove as much commands as possible
2013-09-27T04:14:15 < bighead123> zyp: for example gamma control
2013-09-27T04:14:20 < zyp> no idea, I've never used this display
2013-09-27T04:15:23 < bighead123> zyp: I would now connect 16 leds to any free port and program would out combinations on them when I would press a button, one by one
2013-09-27T04:15:34 < bighead123> right?
2013-09-27T04:15:56 < zyp> oh, by the way, I found out what might be the problem
2013-09-27T04:16:11 < bighead123> zyp: what?
2013-09-27T04:16:27 < zyp> some of the pins you are using are connected to other stuff
2013-09-27T04:16:49 < zyp> PE0 and PE1 are IRQ lines for the accelerometer
2013-09-27T04:17:00 < bighead123> zyp: but I am not using that?
2013-09-27T04:17:25 < zyp> well, did you remove it to the board?
2013-09-27T04:17:27 < zyp> from*
2013-09-27T04:17:40 < bighead123> of course no
2013-09-27T04:18:01 < bighead123> maybe it is setting some pins to always 0?
2013-09-27T04:18:04 < bighead123> or 1?
2013-09-27T04:18:06 < zyp> hang on
2013-09-27T04:19:25 < zyp> yep, they are push-pull
2013-09-27T04:19:46 < zyp> so they will sit at 0
2013-09-27T04:20:10 < zyp> you can actually reconfigure them to open-drain
2013-09-27T04:20:32 < zyp> but that will require writing a register in the accelerometer :p
2013-09-27T04:21:09 < bighead123> zyp: i.e. now some pins are always 0 because of accelerometer?
2013-09-27T04:21:26 < zyp> if you're actually going that route, you'll want to set the bits IHL and PP_OD in CTRL_REG3 in the accelerometer
2013-09-27T04:21:29 < zyp> yep
2013-09-27T04:21:35 < zyp> PE0 and PE1
2013-09-27T04:22:09 < bighead123> zyp: no that is too hard and I'll make tons of new errors, I prefer to resolder all pins to other port
2013-09-27T04:22:42 < zyp> yeah, I'd also do that
2013-09-27T04:22:57 < zyp> you might also want to move PE2 when you're at it
2013-09-27T04:23:29 < zyp> it's also used for something else, but it's only hooked to an input, so it shouldn't affect this signal
2013-09-27T04:23:42 < zyp> but better not be feeding random data to other chip's inputs anyway :p
2013-09-27T04:23:45 < bighead123> zyp: at first I'll set all pins to 1 and check now with multimeter, then to 0 and check again. if they are working then no need for resoldering, Right? or do you think I must resolder all pins?
2013-09-27T04:23:50 < bighead123> *usually
2013-09-27T04:23:55 < zyp> huh?
2013-09-27T04:24:06 < zyp> just move PE0, PE1 and PE2
2013-09-27T04:24:28 < zyp> PE0 and PE1 are driving outputs against outputs, and that's never a good idea
2013-09-27T04:25:01 < bighead123> zyp: how I would write GPIOE->ODR = cmd; after moving them?
2013-09-27T04:25:43 < zyp> well, you'd obviously have to split it in two writes
2013-09-27T04:26:27 < zyp> say you're moving them to PD8-10
2013-09-27T04:26:51 < zyp> hmm
2013-09-27T04:27:22 < zyp> you should really make some wrapper functions for setting pins and pin arrays :p
2013-09-27T04:28:32 < bighead123> zyp: so I need to move all of pins or write some kind of strange function instead of GPIOE->ODR = cmd;
2013-09-27T04:28:32 < bighead123> 1. I would check if all 16 pins are working with multimeter
2013-09-27T04:28:32 < bighead123> 2. add led to any other pin and if LCD responds with correct command it would be turned on
2013-09-27T04:28:32 < bighead123> 3. If this would work, then I have to rewrite commands from beginning.
2013-09-27T04:28:50 < bighead123> zyp: Right plan?
2013-09-27T04:29:05 < bighead123> I would check now and report

2013-09-27T10:00:01 < ohsix> notable? However, for short range applications, the higher frequencies and much higher velocity can prove advantageous. This paper will outline a project which will utilise recent investigations that demonstrate EM wave propagation up to the MHz frequency range is possible in seawater.
2013-09-27T10:00:53 < ohsix> there are a few businesses in there, maybe checking the average range & band they use can give you some idea of what can be done

2013-09-27T10:05:38 < jpa-> it is all a matter of depth
2013-09-27T10:06:14 < ohsix> i'm assuming the depth will be at least as deep as you'd possibly want to communicate

2013-09-27T10:06:51 < ohsix> is there a difference between them?

2013-09-27T10:10:45 < R2COM> I was curious about rf. not ultrasound

2013-09-27T10:12:50 < jpa-> but yeah, i'll just shut up
2013-09-27T10:13:10 < R2COM> you better do
2013-09-27T10:13:32 < R2COM> nothing wrong in discussing something cutting edge sometimes, or asking if someone did anything to do with it
2013-09-27T10:13:34 < ohsix> not impossible, just insanely improbable, you could look into communicating by bullet fragments or something just as plausibly ;D

2013-09-27T13:10:30 < dongs> other parts ship tomorrw
2013-09-27T13:10:43 < dongs> should be all there by like mid next week.
2013-09-27T13:10:47 < dongs> + pcb also
2013-09-27T13:11:51 < zyp> they mailed and asked about what was up with different shipto/billto, so I just explained that I ordered parts to be sent directly to a contract manufacturer
2013-09-27T13:14:11 < zyp> 12:10:17 < dongs> zyp: pcb ordered, you can shitpal minus pcba amount whenever.
2013-09-27T13:14:14 < zyp> how much and where?
2013-09-27T13:15:35 < zyp> karlp, instead of matching devices, can't you just make a catch-all that will make modem manager ignore everything? or does it actually do anything useful for you?
2013-09-27T13:24:05 < karlp> maybe, I didn't look to far,
2013-09-27T13:24:14 < ohsix> udev is generally opt in, not opt out
2013-09-27T13:24:37 < karlp> there's a bunch of cunts that insist that modem-manager is critical for some shit, and they're not interested in acknowledging that not everything with a cdc-acm interface is a modem
2013-09-27T13:24:37 < ohsix> you should be able to short circuit the entire rule file for the modem rules tho
2013-09-27T13:25:01 < karlp> depends how much you want to edit, and how much you want to keep working after an upgrade
2013-09-27T13:25:10 < ohsix> is there a way to verify that they aren't?
2013-09-27T13:25:44 < karlp> read the logs when you plug the device in? I can't remember, but that was the magic I needed to make it leave devices alone,
2013-09-27T13:25:52 < karlp> the bug for it is..... entertaining
2013-09-27T13:26:35 < ohsix> url?
2013-09-27T13:26:46 < karlp> lots of people with totally broken devices because modem-manager opened up CNC machines and started sending AT commands asking for probe info
2013-09-27T13:27:04 < ohsix> the thing about modem manager and stuff like it (like PA for audio devices) is they are the expected interface, unless you tell them to quiesce
2013-09-27T13:27:18 < ohsix> cute haha
2013-09-27T13:27:25 < karlp> ohsix: I might have it at home,
2013-09-27T13:27:48 < karlp> but it was clearly a bug that was NOT going to get fixed anytime in any reasonable time frame, so I don't bother to follow it after I got the workaround
2013-09-27T13:27:53 < ohsix> serial ports are always going to be awful like that
2013-09-27T13:28:36 < karlp> "we must be able to automatically dial into aol without a user having to enter amodem init string!"
2013-09-27T13:28:38 < ohsix> is modemmanager expected to grow to identify devices that aren't modems? or is that supposed to be done elsewhere (i'm gonna look & follow up, i'm presuming they don't want to make things explode)
2013-09-27T13:30:01 < ohsix> hmm, it looks like there should be a trivial way to keep it off serial ports

2013-09-27T13:48:16 < ohsix> karlp: https://bugzilla.gnome.org/show_bug.cgi?id=688213 ?
2013-09-27T13:48:29 < zyp> dongs, minus pcba?
2013-09-27T13:48:33 < zyp> why is that?
2013-09-27T13:48:41 < dongs> well, youc an do all at once if you want
2013-09-27T13:48:49 < ohsix> dongs: it's for 3g cards & basebands in devices D:
2013-09-27T13:48:51 < dongs> im just saying the only part thats in progress now is #1
2013-09-27T13:49:22 < dongs> sam-ba sounds like shit for hacking PS3s
2013-09-27T13:49:35 < dongs> cuz nothing atmel ever made was used for legit things
2013-09-27T13:52:47 <+Steffanx> :P
2013-09-27T13:56:00 < karlp> ohsix: same problem, different bug,
2013-09-27T13:56:11 < karlp> they haven't made the link to the old one yet :)
2013-09-27T13:56:20 < ohsix> karlp: they should be looking at the device properties on the acm shit for sure, any blacklist should be for known bad devices
2013-09-27T13:56:28 < karlp> no, fuck off,
2013-09-27T13:56:33 < karlp> that's what the modem-manager people think
2013-09-27T13:56:49 < karlp> they simply shouldn't start sending characters to devices just in the hope that it might be amodem
2013-09-27T13:56:53 < ohsix> the properties are usb descriptor properties, not anything with the com port
2013-09-27T13:57:18 < ohsix> they don't, really; udev is making a list of all things serial port like, and info is being lost
2013-09-27T13:57:51 < ohsix> udev shouldn't be giving ttyACM* names to stuff
2013-09-27T13:58:23 < ohsix> the blacklist would be for devices that have incorrect descriptors, and they'd be regular usb quirks
2013-09-27T13:58:23 < zyp> why not? it's ACM devices
2013-09-27T13:58:27 < qyx_> why?
2013-09-27T13:58:28 < karlp> like I said earlier, I dont' see any nearterm "fix" to this coming from gnome, so I stopped trying to "solve" it beyond my own use cases.
2013-09-27T13:58:44 < ohsix> right
2013-09-27T13:59:16 < ohsix> it is as it is now because they're not using information they have, and on that bug they say is unreliable (which is true)
2013-09-27T13:59:20 < karlp> I was sharing my udev rule to make modem-manager fuck off because I found that workaround difficult to find at the time
2013-09-27T13:59:30 < ohsix> ah
2013-09-27T13:59:56 < ohsix> since its a property you can set it on all serial devices with one rule
2013-09-27T14:02:57 < ohsix> i wanted to qualify the ttyACM thing when i typed it, oh well
2013-09-27T14:04:08 < ohsix> the whole 'cannot do calls' thing the kernel knows from the descriptor might not even be notable for what MM does
2013-09-27T14:06:14 < karlp> this is probably the bug I had found first, from 2009: https://bugzilla.redhat.com/show_bug.cgi?id=544121
2013-09-27T14:07:33 < karlp> here it is crashing a braille reader: https://bugzilla.gnome.org/show_bug.cgi?id=647556
2013-09-27T14:08:52 < karlp> this is getting some of the way there: https://bugzilla.gnome.org/show_bug.cgi?id=691076
2013-09-27T14:10:23 < ohsix> hm the dude punted on the braille display as something else calling Scan
2013-09-27T14:11:15 < karlp> sure, but same shit
2013-09-27T14:11:52 < ohsix> yea
2013-09-27T14:12:52 < ohsix> the thing about using the kernel information is you can put the ad-hoc list of things in one place, and where you can reasonably ignore or change things in the descriptor
2013-09-27T14:13:03 < ohsix> they're sucking at that
2013-09-27T14:18:29 < ohsix> oof they've agglomerated a lot of stuff that's not really 'modem' management
2013-09-27T14:31:57 < dongs> did you know? lunix still sucks on desktop
2013-09-27T14:32:05 < dongs> lol @ "modem manager"
2013-09-27T14:32:14 < dongs> does anyone seriously use or care about that shit
2013-09-27T14:32:46 < zyp> apparently gnomes do
2013-09-27T14:33:02 < dongs> http://www.kickstarter.com/projects/920064946/oscilloscope-watch pretty sure i tweeted this already.
2013-09-27T14:33:07 < dongs> something about using failmega in 2013
2013-09-27T14:33:09 <+Steffanx> Im very sure.
2013-09-27T14:33:10 < zyp> you did
2013-09-27T14:33:22 < zyp> still looks just as shitty
2013-09-27T14:33:31 < ohsix> dat 3g modem
2013-09-27T14:34:55 < Laurenceb> fail 3d printing
2013-09-27T14:35:21 < Laurenceb> i need to do injection molding for the next version of my datalogger
2013-09-27T14:35:35 < Laurenceb> but hammond cases are better than 3d printing for now
2013-09-27T14:36:01 < Laurenceb> also.. why oscilloscope on a watch
2013-09-27T14:36:03 < Laurenceb> WTF
2013-09-27T14:36:25 < qyx_> why not if theres enough funding and opportunity to grab some money
2013-09-27T14:36:54 < ohsix> missing a comma, as far as 3d printers go that's a pretty ok print
2013-09-27T14:37:16 < qyx_> sometimes i think that kickstarter is nothing more than a way to get money
2013-09-27T14:37:26 < Laurenceb> well durrr
2013-09-27T14:37:57 < ohsix> kickstarter is the hip way to flog your stuff now
2013-09-27T14:39:08 < qyx_> of course if useless things could be called stuff
2013-09-27T14:39:23 < ohsix> sure
2013-09-27T14:39:44 < ohsix> people like stuff that seems neat to them
2013-09-27T14:39:45 < dongs> holy shit
2013-09-27T14:39:50 < dongs> i just saw a google ad for Able-HD
2013-09-27T14:40:44 < ohsix> why don't they just make a smartphone widget if they're going to have a smartphone interface
2013-09-27T14:41:28 < qyx_> dongs: you see, if you have placed your converter on ks you would have 100K now
2013-09-27T14:42:02 <+Steffanx> And have the screwed over like the openviszla guys did? :P
2013-09-27T14:42:03 < ohsix> he doesn't like money
2013-09-27T14:42:03 < dongs> http://i.imgur.com/3Th3jRl.png
2013-09-27T14:42:21 < dongs> seriously tho, why the fuck would they bother buying ads
2013-09-27T14:42:21 < dongs> they already have 100k from retards
2013-09-27T14:42:40 < ohsix> more retards, dude
2013-09-27T14:43:01 < ohsix> the fact that people are giving them money is very conducive to other people doing so
2013-09-27T14:43:23 < ohsix> you can influence the rate at which that is done ...
2013-09-27T14:44:23 < ohsix> karlp: brltty should be using exclusive mode :<
2013-09-27T14:46:26 < ohsix> http://cgit.freedesktop.org/ModemManager/ModemManager/tree/src/mm-port-probe.c#n763 heh
2013-09-27T14:47:23 < ohsix> i'm guessing the serial port status lines are mostly ignored by the usb widgets?
2013-09-27T14:48:27 < ohsix> hm the at probe is conditional
2013-09-27T14:50:22 < ohsix> it seems to really skip the usb devices
2013-09-27T14:51:14 < ohsix> oh well, no time left for that
2013-09-27T14:51:39 < zyp> ohsix, yeah
2013-09-27T14:52:13 < zyp> no need to care about baudrate and flow control if it's a virtual device
2013-09-27T14:53:42 < ohsix> my knowledge of serial ports is so far gone i can't even go down that road
2013-09-27T14:54:55 < ohsix> opening the serial port in exclusive mode for the chip programmers or whatever is kind of out of the question, but it can solve the brltty problem
2013-09-27T14:55:31 < Laurenceb> http://www.portertech.org/test/transformer-laptop.flv
2013-09-27T14:56:42 <+Steffanx> old video is old, but nice :P

2013-09-27T15:51:54 < zyp> patent troll?
2013-09-27T15:53:42 < Thorn> lots of "mosaid sues apple over wifi" links
2013-09-27T15:54:44 < Thorn> how are these lawsuits normally resolved? a settlement and the company continues selling "infringing" products?
2013-09-27T15:55:20 < ohsix> that's the gambit
2013-09-27T15:55:33 < ohsix> licensing is cheaper than invalidating the patent
2013-09-27T15:55:52 < ohsix> everything is super low risk for the troll

2013-09-27T20:13:18 < karlp> emeb: you weren't here earlier: /dev/serial/by-id/* has all the /dev/ttyXXXX devices listed by the serial nbumbers already (might help yoiu with some of your udev stuff)
2013-09-27T20:13:34 < karlp> and if you find the logs, you can find udev snippets to make modem-manager ignore shit
2013-09-27T20:14:29 < emeb> karlp: thanks!
2013-09-27T20:14:53 < emeb> I think that nuking modem-manager was the critical step
2013-09-27T20:15:17 < karlp> well, rm -rf modem-manager does work yes :)
2013-09-27T20:17:11 < emeb> not only did that thing prevent me from accessing the device, but it also confused the BMP, leaving it in an unusable state.
2013-09-27T20:17:50 < karlp> yeah, it sends AT commands trying to prove the capabilities
2013-09-27T20:19:34 < Thorn> I hope there're no linux-controlled weapon systems with serial interfaces and protocols where 'AT' means something
2013-09-27T20:25:55 < gxti> it's annoying in gdb not being able to use the symbols from stm32f10x.h whenever the file i'm currently at, which is usually coos' idle loop, does not have that file included. because they're all macros, not actual symbols, and macros are only usable when the context is a file where those macros are defined.

2013-09-27T21:04:01 < Posterdati> hi
2013-09-27T21:04:42 < zyp> hi
2013-09-27T21:04:48 < jpa-> hi
2013-09-27T21:04:50 < zyp> how's your usb stuff going?
2013-09-27T21:23:39 < Posterdati> zyp: bad,
2013-09-27T21:23:48 < Posterdati> zyp: bad, it's slo
2013-09-27T21:23:49 < Posterdati> zyp: bad, it's slow
2013-09-27T21:24:02 < jpa-> are you typing through it now? :P
2013-09-27T21:24:15 < Posterdati> 3200Hz is too fast for usb
2013-09-27T21:24:41 < jpa-> did you try a isochronous endpoint?
2013-09-27T21:24:45 < Posterdati> no
2013-09-27T21:25:12 < jpa-> it has guaranteed bandwidth.. though if there is crc fail, it won't retransmit
2013-09-27T21:25:18 < zyp> 3200Hz is not too fast for usb, you just have to not be dumb
2013-09-27T21:25:31 < Posterdati> I'm not
2013-09-27T21:25:31 < zyp> remember that usb audio can easily do 48000Hz
2013-09-27T21:25:40 < Posterdati> usb.write waste a lot of time
2013-09-27T21:26:01 < jpa-> zyp: didn't you even have usb audio working perfectly well with laks?
2013-09-27T21:26:08 < zyp> yep
2013-09-27T21:26:18 < Posterdati> in the mean time buffer grows
2013-09-27T21:26:22 < zyp> output though, Posterdati is trying to do input
2013-09-27T21:26:29 < jpa-> true
2013-09-27T21:26:57 < zyp> Posterdati, that means that your host is not requesting data fast enough, that's where the dumbness is
2013-09-27T21:27:44 < Posterdati> and how can I fix that?
2013-09-27T21:27:56 < jpa-> hmm.. does the size of the requests that the host software matter?
2013-09-27T21:28:00 < zyp> well, first of all you can tell me what you are doing on the host side
2013-09-27T21:28:14 < zyp> then I can tell you how it is dumb and how you should fix it
2013-09-27T21:28:15 < Posterdati> I'm bulk reading
2013-09-27T21:28:16 < zyp> jpa-, yes
2013-09-27T21:28:24 < Posterdati> using a thread
2013-09-27T21:28:24 < zyp> Posterdati, with libusb?
2013-09-27T21:28:27 < Posterdati> yes
2013-09-27T21:28:36 < zyp> and you are requesting 64 bytes at a time?
2013-09-27T21:28:41 < Posterdati> yes
2013-09-27T21:28:46 < zyp> ok, that's dumb.
2013-09-27T21:29:02 < Posterdati> ok, what then?
2013-09-27T21:29:25 < zyp> increase that number to some kilobytes or whatever you think would be acceptable latency
2013-09-27T21:29:35 < zyp> larger transfer size = more latency, less overhead
2013-09-27T21:29:36 < Posterdati> on the host side?
2013-09-27T21:29:41 < zyp> yes
2013-09-27T21:29:58 < Posterdati> just in the usb_bulk_read?
2013-09-27T21:30:04 < zyp> yes
2013-09-27T21:30:21 < Posterdati> ok
2013-09-27T21:30:22 < zyp> the transfer size on the host side defines how many packets the host controller/stack will request at a time
2013-09-27T21:30:30 < Posterdati> ok
2013-09-27T21:31:05 < zyp> remember that the host has a lot of overhead passing stuff between the host controller hardware and the userspace software
2013-09-27T21:31:22 < zyp> and if you do that for every single 64B packet, it's no wonder you can't keep up
2013-09-27T21:31:36 < Posterdati> ok, let's see
2013-09-27T21:31:43 < Posterdati> I put 512B at time
2013-09-27T21:31:58 < Posterdati> host bulk read 512B at time
2013-09-27T21:32:29 < zyp> also, are you using the synchronous or async API?
2013-09-27T21:33:07 < zyp> you should be using async, that way you can schedule multiple transfers
2013-09-27T21:33:20 < zyp> so there is always a new one ready to start once the previous is full
2013-09-27T21:33:51 < Posterdati> http://libusb.sourceforge.net/doc/
2013-09-27T21:34:32 < zyp> wat, are you using libusb-0.1?
2013-09-27T21:34:38 < Posterdati> yes
2013-09-27T21:34:48 < zyp> that's also dumb
2013-09-27T21:34:53 < Posterdati> what shall I use?
2013-09-27T21:35:02 < zyp> http://libusb.org/ <- 1.0

2013-09-28T03:05:36 < zyp> I think they sort of merged them
2013-09-28T03:05:40 < dongs> does it still install a filter driver on top of e very windows USB device?
2013-09-28T03:05:52 < zyp> libusb.org now links to libusbx here and there
2013-09-28T03:05:53 < dongs> if it does, its still fucking fail.
2013-09-28T03:06:07 < Thorn> afaik Mr. CareBear calls it a hostile takeover and refuses to accept it
2013-09-28T03:06:35 < zyp> dongs, didn't do it when I used it
2013-09-28T03:07:06 < zyp> I just had to load WinUSB driver for the device I wanted to use, then libusb could access it
2013-09-28T03:07:22 < zyp> so on windows it's more or less a wrapper API over WinUSB
2013-09-28T03:13:37 < dongs> so i'd just use winusb
2013-09-28T03:13:44 < dongs> so i dont have to link with aids.

2013-09-28T03:26:06 < Thorn> night
2013-09-28T03:26:06 < zyp> how so?
2013-09-28T03:26:27 < zyp> a ZLP or short packet should terminate a transfer early, no?
2013-09-28T03:26:47 < Thorn> that's what I'd expect
2013-09-28T03:26:59 < zyp> but that's not what happens?
2013-09-28T03:27:35 < Thorn> I guess the question is, should the app or the library worry about that
2013-09-28T03:27:42 < dongs> wut
2013-09-28T03:27:46 < dongs> what hte fuck is a zero length packet?
2013-09-28T03:27:50 < dongs> control transfer with no data?
2013-09-28T03:28:04 < zyp> no, just a data packet with no data
2013-09-28T03:28:08 < dongs> lenght = 0, and just using index + bla field?
2013-09-28T03:28:11 < dongs> uh.. wat
2013-09-28T03:28:13 < dongs> whats hte point?
2013-09-28T03:28:25 < Thorn> dongs: bulk/interrupt, not control
2013-09-28T03:28:27 < zyp> the point is that transfers can consist of multiple packets
2013-09-28T03:28:32 < zyp> Thorn, control too
2013-09-28T03:29:07 < zyp> if max packet size is 64 bytes, and you want to send a transfer of exactly 128, you have to send 64+64+0
2013-09-28T03:29:23 < dongs> why?
2013-09-28T03:29:26 < zyp> because a packet of max size means that another will follow in the same transfer
2013-09-28T03:29:35 < zyp> while a smaller packet means it's the last in the transfer
2013-09-28T03:29:48 < Thorn> well I mean control is sort of supposed to be handled correctly or nothing else is going to work
2013-09-28T03:29:54 < zyp> because there is no other mechanism to communicate the transfer size
2013-09-28T03:29:55 < dongs> I'm pretty sure i've sent exactly packet boundaries before and had no problems.
2013-09-28T03:29:56 < emeb> ah - just a simple EOF marker.
2013-09-28T03:30:09 < Thorn> EOT
2013-09-28T03:30:11 < dongs> would winusb just work like that?
2013-09-28T03:30:18 < dongs> without extra fuckery.
2013-09-28T03:30:25 < zyp> dongs, it depends on what you are doing
2013-09-28T03:30:28 < emeb> Thorn: yep :)
2013-09-28T03:31:00 < Thorn> dongs: see the SHORT_PACKET_TERMINATE flag (for OUT transfers)
2013-09-28T03:31:11 < zyp> frame oriented protocols that sends frames that might be larger than single packets would normally use this mechansm to distinguish frames
2013-09-28T03:31:25 < zyp> like CDC ethernet and whatnot
2013-09-28T03:31:43 < dongs> Thorn: im talkin winusb, not opensoresusb
2013-09-28T03:31:44 < zyp> for bytestream protocols like CDC ACM it won't matter at all
2013-09-28T03:32:08 < Thorn> dongs: http://msdn.microsoft.com/en-us/library/windows/hardware/ff728833(v=vs.85).aspx
2013-09-28T03:32:23 < dongs> ic ok
2013-09-28T03:32:24 < dongs> cool
2013-09-28T03:33:48 < zyp> Thorn, I've been burned by not terminating a descriptor read with a ZLP when a descriptor is exactly 64 bytes
2013-09-28T03:33:58 < zyp> so the mechanism is certainly used for control in transfers too
2013-09-28T03:34:09 < Thorn> when implementing a host?
2013-09-28T03:34:14 < zyp> device
2013-09-28T03:34:27 < Thorn> okay right
2013-09-28T03:34:48 < zyp> I dicked up some fun stuff tonight
2013-09-28T03:35:25 < zyp> got a nfc card reader, reading an ID from a card, and presents it as a file on a fat file system over mass storage
2013-09-28T03:35:46 < dongs> how's that bitbanged usb doing
2013-09-28T03:36:17 < zyp> you're gonna ask about that until I'm actually bored enough to do it?
2013-09-28T03:37:12 < dongs> probly
2013-09-28T03:37:35 < dongs> it can be done on avrturd, cant be THAT hard on stm.
2013-09-28T03:37:44 < zyp> true
2013-09-28T03:38:03 < dongs> you could then dickstarter it
2013-09-28T03:38:19 < dongs> hm so 32gig microsd def trolled me
2013-09-28T03:38:29 < dongs> most files read back as zeros
2013-09-28T03:38:39 < dongs> not sure if its 4gig or 8gig real
2013-09-28T03:39:05 < zyp> like how? «buy this microcontroller with actual hardware usb support, then run my bitbanged usb on it instead»
2013-09-28T03:39:29 < dongs> yes
2013-09-28T03:39:40 < dongs> "use any pin for usb interface*"
2013-09-28T03:39:49 < zyp> maybe emeb would find use for it, I remember he wired a board with the speed pullup on the wrong signal once
2013-09-28T03:41:08 < zyp> well, bedtime.
2013-09-28T03:41:36 < Thorn> make sure to mention arduino at least 15 times
2013-09-28T03:41:45 < Thorn> will work great
2013-09-28T03:42:25 < Thorn> found a russian dickstarter clone, someone there tried to raise funds for external audio interfaces twice and failed

2013-09-28T03:46:09 < emeb> yeah
2013-09-28T03:46:16 < emeb> I've done something kinda like that.
2013-09-28T03:46:25 < emeb> single-chip USB->Audio
2013-09-28T03:46:34 < emeb> ain't no big thing.
2013-09-28T03:46:35 < Thorn> 3.5mm connectors look like the crappiest kind available
2013-09-28T03:46:58 < emeb> that kind are actually pretty good.

2013-09-28T03:47:39 < emeb> better than the smd crap most low-end asian stuff uses.

2013-09-28T03:48:12 < dongs> lol
2013-09-28T03:48:26 < dongs> v2 got even less cash tho
2013-09-28T03:48:34 < Thorn> well I probably have chinese clones that look the same

2013-09-28T03:50:35 < dongs> burr brown usb audio codec 2704
2013-09-28T03:50:45 < dongs> did he just put thaqt chip on a pcb
2013-09-28T03:50:46 < emeb> hah - thought so
2013-09-28T03:50:56 < emeb> I used something similar.
2013-09-28T03:51:00 < dongs> and it has stanadr drivers etc?
2013-09-28T03:51:05 < dongs> no mcu involved
2013-09-28T03:51:09 < emeb> USB Audio class compliant
2013-09-28T03:51:14 < Thorn> I need to finally finish my audio board

2013-09-28T03:54:52 < Thorn> they tried to raise only ~$4k for 100 units, doesn't look as exorbitant as those kickstarter projects ($80k for a led or what that was)
2013-09-28T03:55:47 < dongs> heh

2013-09-28T06:27:16 < Thorn> In Windows 8.1 Preview, new WinUSB Functions have been added to the API set that allow a desktop app to send data to and receive data from isochronous endpoints.
2013-09-28T06:32:27 < dongs> cool
2013-09-28T06:32:56 < emeb_mac> what's that good for?
2013-09-28T06:33:40 < dongs> nothing raelly, only broken devices use isoch transfers
2013-09-28T06:34:31 < emeb_mac> hah.
2013-09-28T06:35:02 < emeb_mac> IIRC isoch was initially conceived for media type stuff, but none of the normal media classes use it.
2013-09-28T06:36:22 < Thorn> like audio class?
2013-09-28T06:36:32 < emeb_mac> ifinkso
2013-09-28T06:36:44 < Thorn> okay
2013-09-28T06:37:51 < emeb_mac> was digging through my inventory of parts - found 3x STM32F405RG in a box.
2013-09-28T06:38:04 < emeb_mac> now I need to think of something useful to do with them :P
2013-09-28T06:38:55 < Thorn> I'm compiling an order, it's close to $300 now x_x
2013-09-28T06:41:15 < emeb_mac> yeow!
2013-09-28T06:41:20 < emeb_mac> what are you making?
2013-09-28T06:41:31 < GargantuaSauce> i do that whenever i go on mouser
2013-09-28T06:41:42 < GargantuaSauce> i suffer from kid-in-a-candy-store syndrome something fierce
2013-09-28T06:42:03 < emeb_mac> "one of these, and one of these, and one of these...."
2013-09-28T06:42:07 < GargantuaSauce> yeeeup
2013-09-28T06:42:25 < Thorn> one is expensive,10 is usually cheaper x_x
2013-09-28T06:42:34 < GargantuaSauce> yeah it ends up being 10 or 50
2013-09-28T06:42:36 < emeb_mac> cheaper by the dozen!
2013-09-28T06:43:23 < Thorn> as usual I'm preparing several projects so I can order a single panel
2013-09-28T06:43:25 < emeb_mac> when buying parts for a project I usually by 1 more than I need, just in case. I've got a lot of onsies sitting around...
2013-09-28T06:44:52 < Thorn> does that include $17k FPGAs?
2013-09-28T06:45:02 < emeb_mac> heh
2013-09-28T06:45:22 < emeb_mac> Not $17k - just $2500/ea. We bought 4 I think...

2013-09-28T07:15:28 < Thorn> by reading single packet in a loop?

2013-09-28T07:32:33 < dongs> I was just recently asked about exact same type of project idea, but for medical ultrasound imaging. The brilliant idea they have is that most of the cost of medical imaging is in the display, so if they replace the graphical display with an iPad, they could produce it for a fraction of the cost. Just design an ultrasound probe that we could plug into an iPhone or iPad -- it should be easy with an Arduino.

2013-09-28T07:34:35 < Thorn> the reason why medical displays are expensive is that they're special, right? and I think it's not just resolution, but also color depth
2013-09-28T07:35:34 < R0b0t1> I'm really gonna go for markup
2013-09-28T07:35:52 < R0b0t1> I mean medical electronics are tested and fit certain safety criteria
2013-09-28T07:35:53 < R0b0t1> but
2013-09-28T07:35:56 < R0b0t1> it's mostly markup
2013-09-28T07:36:58 < GargantuaSauce> all the more reason to involve apple products and arduinos
2013-09-28T07:38:02 < R0b0t1> lel
2013-09-28T07:38:19 < Thorn> how much data does an ultrasound sensor generate? can you do all the processing in an avr?
2013-09-28T07:38:45 < GargantuaSauce> it's some pretty fancy dsp
2013-09-28T07:39:15 < ohsix> heh why are the displays the expensive part :<
2013-09-28T07:39:31 < ohsix> the ultrasound head, cabling is the expensive part
2013-09-28T07:39:31 < GargantuaSauce> imaging from a phased array after all, sample rate would be a few tens of mhz i imagine
2013-09-28T07:39:49 < ohsix> oh so the display means the big box that does all the work? :p
2013-09-28T07:40:07 < ohsix> an ipad isn't going to be able to be cleared as a medical device either
2013-09-28T07:40:07 < GargantuaSauce> okay let's say we're just talking about the image then
2013-09-28T07:40:54 < ohsix> any hypothetical ultrasound widget for the ipad would have it being a really dumb display, it's not going to be able to do the imaging, it'd be some outbound thing
2013-09-28T07:41:25 < GargantuaSauce> over one of the multitude of accessible and high-bandwidth io ports the ipad ofers
2013-09-28T07:41:37 < R0b0t1> Thorn: Ultrasound is a lot of DSP
2013-09-28T07:41:48 < R0b0t1> the stuff driving the sensors would be more powerful than an AVR
2013-09-28T07:41:56 < ohsix> at least it could have wifi in it, like all the other ossum vestigial ipad projects on kickstarter
2013-09-28T07:41:57 < Thorn> that's what I thought
2013-09-28T07:43:48 < emeb_mac> R0b0t1 is right - the analog & DSP front ends for ultrasound are hairy.
2013-09-28T07:44:21 < emeb_mac> plus, bear in mind that as medical equipment, all that stuff has to be very extensively tested and approved by federal agencies
2013-09-28T07:44:34 < emeb_mac> getting it built is $$$
2013-09-28T07:44:53 < ohsix> you could act like it wasn't for medical applications :]

2013-09-28T07:45:35 < emeb_mac> ohsix: right. and then when a Dr. uses it and gets sued, you end up getting sued too. Covered for that?
2013-09-28T07:45:53 < ohsix> why would you have anything to do with what the doctor is doing
2013-09-28T07:46:45 < emeb_mac> ohsix: has _nothing_ to do with logic. Lawyers in medical cases go after everyone. The doctors, the hospitals, the equipment makers, the guy who sweeps the floors.
2013-09-28T07:47:22 < ohsix> going after kraft cuz the doctor also had some candy the day before
2013-09-28T07:47:32 < emeb_mac> yep - you got it.

2013-09-28T09:34:20 < GargantuaSauce> allow me to interject
2013-09-28T09:34:49 < GargantuaSauce> what you're referring to as PonyOS is in fact GNU/PonyOS, or as I've recently taken to calling it, GNU Plus PonyOS
2013-09-28T09:35:29 < GargantuaSauce> PonyOS is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS

2013-09-28T10:01:00 < Robint91> is it possible to stream MJPEG with the STM32 over wifi

2013-09-28T10:01:59 < Robint91> camera ( that outputs MJPEG) -> (DCMI) STM32 -> WIFI module
2013-09-28T10:02:26 < emeb_mac> all depends on the data rates I guess.
2013-09-28T10:03:01 < emeb_mac> wifi is theoretically capable of 54Mbps, but who knows how much overhead and if your wifi module can go that fast.
2013-09-28T10:03:19 < emeb_mac> and what's the data rate out of your camera?
2013-09-28T10:03:25 < Robint91> emeb_mac, it is 30kB per frame
2013-09-28T10:03:33 < Robint91> and I can go to 30 fps with the camera
2013-09-28T10:03:35 < Robint91> I think
2013-09-28T10:03:48 < emeb_mac> so 900kbps?
2013-09-28T10:03:49 < GargantuaSauce> i am not too familiar with MJPEG. are all the frames exactly the same size?
2013-09-28T10:03:56 < Robint91> 7.2Mbps
2013-09-28T10:04:03 < Robint91> GargantuaSauce, more or less
2013-09-28T10:04:12 < GargantuaSauce> exactly is the key word here
2013-09-28T10:04:29 < Robint91> GargantuaSauce, depends on the huffman encoding
2013-09-28T10:04:34 < GargantuaSauce> so no
2013-09-28T10:04:57 < GargantuaSauce> pretty sure dma with the DCMI interface doesn't work unless you know the exact amount of data coming in
2013-09-28T10:05:24 < Robint91> GargantuaSauce, the DCMI supports JPEG streams
2013-09-28T10:05:44 < qyx_> i suppose this would work
2013-09-28T10:05:55 < qyx_> i was able to get 700KB/s over ethernet
2013-09-28T10:05:58 < qyx_> on f107
2013-09-28T10:07:36 < qyx_> over tcp
2013-09-28T10:09:41 < qyx_> 802.11b wifi won't go beyond ~5-6mbps, 802.11g is capable of about 22-25mbps in good conditions with snr > 20dB
2013-09-28T10:10:06 < Robint91> I can live with 10fps
2013-09-28T10:10:17 < GargantuaSauce> ok looks like the caveat is that you transfer the upper bound of the frame size in, and then you have to figure out how much of the data is padding zeros
2013-09-28T10:10:31 < Robint91> so I only need 2.4Mbps

2013-09-28T14:12:03 < zyp> Thorn, yeah, a six year old document is probably the best source of info

2013-09-28T14:12:45 < zyp> strange
2013-09-28T14:12:50 < Posterdati> I submit the transfer

2013-09-28T14:13:50 < Thorn> they link to it everywhere
2013-09-28T14:13:53 < Thorn> it does
2013-09-28T14:13:58 < Posterdati> zyp: I did a state machine
2013-09-28T14:14:33 < Thorn> like this: "It is a different technology compared to LiIon, but will be discussed as Li-Ion in this application note."
2013-09-28T14:14:40 < zyp> ah, right
2013-09-28T14:14:48 < zyp> just didn't see it listed in the table
2013-09-28T14:16:21 < zyp> so, what's the summary of that document?
2013-09-28T14:18:37 < zyp> heh, I'm reading the conclusion as «li-ion batteries are good, then use our li-ion charger chips» :p
2013-09-28T14:18:45 < Thorn> Li-Ion are good and almost as cheap as Ni*. Use our charge controllers.
2013-09-28T14:18:59 < Thorn> pretty much lol.
2013-09-28T14:19:25 < zyp> well, then it's pretty up to date then
2013-09-28T14:19:47 < Thorn> those chips are still in production
2013-09-28T14:20:04 < zyp> yeah, I think I've used one of those

2013-09-28T14:22:23 < zyp> at the low consumption I had, the battery was pretty much empty when it hit 3.6V

2013-09-28T14:24:03 < Thorn> hm intetesting. so boosting it would be pointless
2013-09-28T14:24:17 < Thorn> that makes things easier
2013-09-28T14:25:11 < zyp> it's probably lower with a higher load, due to internal resistance
2013-09-28T14:25:50 < zyp> this was a 3-400 MAh battery, and the x axis is minutes
2013-09-28T14:26:06 < zyp> mAh*
2013-09-28T14:26:15 < zyp> so I guess around 30-40 mA load
2013-09-28T14:26:35 < Thorn> sounds more or less what I'm going to have

2013-09-28T15:43:42 < Robint91> ohsix, selecting on sysfs path isn't possible
2013-09-28T15:43:56 < Robint91> so you need to look at the tree
2013-09-28T15:44:07 < ohsix> ehh, that wasn't the point; but sure
2013-09-28T15:44:14 < ohsix> there aren't really multiple parents
2013-09-28T15:44:25 < ohsix> it's a flat namespace
2013-09-28T15:45:33 < Robint91> ohsix, I have this
2013-09-28T15:45:33 < Robint91> https://gist.github.com/anonymous/6741729
2013-09-28T15:45:45 < ohsix> it does suck picking out which level to match on, but udevadm info can tell you the whole path; the only thing it can't tell you is where other rules are at that might clobber what you're setting
2013-09-28T15:46:20 < Robint91> ohsix, so SUBSYSTEM=="hidraw", ATTRS{bInterfaceNumber}=="00", ATTRS{idVendor}=="2575", ATTRS{idProduct}=="fa10", MODE="0666" should match
2013-09-28T15:46:50 < Robint91> I use >>> udevadm info --attribute-walk --path=`udevadm info -q path -n /dev/hidraw1`
2013-09-28T15:46:53 < Robint91> to get the udev info
2013-09-28T15:49:03 < ohsix> heh
2013-09-28T15:51:52 < Robint91> ohsix, so strange
2013-09-28T15:52:00 < Robint91> I suspect that it should match
2013-09-28T15:52:40 < ohsix> it won't match hidraw, it doesn't have any of those ATTRS
2013-09-28T15:53:15 < ohsix> isn't there already a rule for uaccess on all hidraw devices, if you need them or something
2013-09-28T15:53:34 < Robint91> ohsix, no
2013-09-28T15:54:05 < Robint91> ohsix, if you look in the gist
2013-09-28T15:54:22 < Robint91> ohsix, you see on line 14     DRIVERS=="usbhid"
2013-09-28T15:54:33 < Robint91> so I can match on     ATTRS{bInterfaceNumber}=="00"
2013-09-28T15:54:50 < Robint91> but how do I match on     ATTRS{idVendor}=="2572"
2013-09-28T15:54:50 < Robint91>  and ...
2013-09-28T16:00:29 < ohsix> the thing is, the hidraw device doesn't have that information
2013-09-28T16:01:35 < ohsix> is there a reason why you're trying to be that specific, instead of just putting uaccess on hidraw?
2013-09-28T16:01:41 < ohsix> or just the mode, really
2013-09-28T16:05:01 < ohsix> just because you can go up the tree on something like hidraw to the device it's actually from, it doesn't mean it's really related to it, aside from it being the parent in sysfs
2013-09-28T16:10:20 < ohsix> you could add an attr higher up the tree on the device that matches, and if there's more than one set of hidraw devices you can mark them all
2013-09-28T16:11:29 < ohsix> or you can cheat and just change the group on all of them, and arrange to be in that group
2013-09-28T16:12:37 < Robint91> ohsix, it is only one part of a device where I need direct hidraw access too
2013-09-28T16:12:51 < Robint91> ohsix, it is a general solution of my device
2013-09-28T16:12:58 < Robint91> so it needs to be clean
2013-09-28T16:13:19 < Robint91> ohsix, making all hidraw 0666 isn't really a clean option
2013-09-28T16:13:42 < ohsix> right, i get what you want to do
2013-09-28T16:14:01 < ohsix> but you're trying to put in a udev rule that it's ok to access one hidraw device while the rest aren't ok
2013-09-28T16:14:59 < ohsix> only one user is implied in what you're doing, but it gives everyone access, uaccess & cooperation is how devices are normally shared based on which user you are
2013-09-28T16:16:32 < Robint91> ohsix, what should I do than?
2013-09-28T16:17:00 < Robint91> my program that most users run needs acces to /dev/hidraw

2013-09-28T16:17:57 < Robint91> which is a cleaner option
2013-09-28T16:18:24 < ohsix> why do they need the hidraw interface?
2013-09-28T16:18:45 < Robint91> ohsix, because I made that it works with default hid reports
2013-09-28T16:18:55 < Robint91> because that is supported everywhere
2013-09-28T16:19:01 < ohsix> oof
2013-09-28T16:19:23 < ohsix> well, if you overspecify access you're going to have people being able to read other peoples keyboards and stuff when you might not want them to
2013-09-28T16:19:44 < Robint91> ohsix, indeed
2013-09-28T16:21:30 < ohsix> http://cgit.freedesktop.org/systemd/systemd/tree/src/login/70-uaccess.rules this is the junk people do when the foreground user has implied access to something, and systemd or consolekit changes acls for you when the foreground user changes
2013-09-28T16:21:59 < ohsix> i don't think you have a n ice way to do this,e ven with uaccess someone can keep the hidraw interface open and sniff passwords
2013-09-28T16:22:55 < ohsix> just do it the dumb way with a huge disclaimer ;D any access you give to the device lets them do it, even if it's sudo or policykit or anything; they have to cooperate to not make it a security problem, at least with sudo they know about it
2013-09-28T16:25:58  * Robint91 just makes hidraw 666
2013-09-28T16:28:51 < Robint91> ohsix, so this is wrong

2013-09-28T16:30:11 < Laurenceb__> devil mode
2013-09-28T16:30:17 < ohsix> one is that it's a README type thing that's already named 99-hid.rules, and the rules in it make no sense

2013-09-28T16:54:40 < karlp> gxti: using -ggdb3 instead of -g to build should let you use alllll macros
2013-09-28T17:01:48 <+dekar__> I think on OSX and Windows one can only open HID devices that don't have a specific (keyboard, mouse) driver loaded. Seems like a decent solution to me.
2013-09-28T17:02:31 < ohsix> on windows if it was a 'hid' device then at least one driver is already loaded and bound to it
2013-09-28T17:02:36 < ohsix> a few, actually
2013-09-28T17:03:20 < ohsix> they don't give you raw access to devices tho, you can't just read the hid reports off random ones; on windows you might be able to install a filter driver that does it but you could just read the keyboard too
2013-09-28T17:03:38 < ohsix> dunno what osx does, probably doesn't let you use anything but an input interface on top
2013-09-28T17:04:21 < ohsix> the real issue is that hidraw gives you all of the information just for the sake of the small bit you need, and that implies reading the keystrokes of any hid device at the same time
2013-09-28T17:05:15 < ohsix> usb is kind of gross, he could unbind the hid driver and do it himself with libusb or something though
2013-09-28T17:06:08 < ohsix> the way those sort of problems are solved is by arbitration, since things need to cooperate, that implies some sort of daemon that _is_ allowed, but known not to read everyones passwords :p and then using that to do what you must
2013-09-28T17:09:20 < ohsix> what was it you needed to do anyways, Robint91?
2013-09-28T17:10:19 < ohsix> aside from having uniform access at that level, like you've already mentioned
2013-09-28T17:15:33 < Robint91> dekar__, yeah you can that on osx and windows
2013-09-28T17:16:06 < Robint91> ohsix, you can read random hid devices
2013-09-28T17:16:21 < Robint91> on windows
2013-09-28T17:16:46 < ohsix> not the one that's on the window station with the unlock screen ...
2013-09-28T17:17:29 < ohsix> you can still have a filter driver that does it, but if you use directinput or whatever you'll lose the driver when the window station changes
2013-09-28T17:17:31 < Robint91> ohsix, the whole point that I use HID is because you have "easy" access to those devices
2013-09-28T17:17:49 < Robint91> ohsix, https://github.com/signal11/hidapi
2013-09-28T17:17:57 < Robint91> ohsix, no directinput needed
2013-09-28T17:18:01 < ohsix> right, but what's wron gwith like, using input/evdev on linux?
2013-09-28T17:18:25 < Robint91> ohsix, bidirectional information?
2013-09-28T17:18:50 < dongs> the fact that nobody fucking uses lunix
2013-09-28T17:18:52 < ohsix> Robint91: you don't get errors when you switch window stations on windows? (lock the screen, basically, but you can fast user switch to the login too)
2013-09-28T17:18:53 < dongs> is the problem.
2013-09-28T17:19:00 < dongs> writing an app that onyl works on lunix = suicide
2013-09-28T17:19:14 < ohsix> because that surely implies that
2013-09-28T17:19:15 < Posterdati> dongs: I use linux, maybe you're not so smart...
2013-09-28T17:19:19 < Robint91> dongs, and what is writing an app that works everywhere?
2013-09-28T17:19:27 < dongs> Robint91: everywehre = windows
2013-09-28T17:19:33 < ohsix> writing a program that lets you read passwords off the login screen only on lunix == great
2013-09-28T17:19:48 < Posterdati> dongs: completely wrong, 90% of interbet servers are unix/linux
2013-09-28T17:19:49 < dongs> yeah, youre gonna get all 10 passwords

2013-09-28T21:17:15 < Robint91> Steffanx, it is a 5 hour drive for me
2013-09-28T21:17:44 <+Steffanx> but i guess you trust you car dekar__

2013-09-28T21:18:11 <+Steffanx> There is always trouble.
2013-09-28T21:18:11 <+dekar__> I don't trust german autobahns not to have traffic jams

2013-09-28T21:25:21 <+Steffanx> I was going to try the fnet port some one made for chibios, but .. dont got the parts to try yet.
2013-09-28T21:26:16 <+dekar__> Steffanx, how much would the train cost to hamburg?
2013-09-28T21:26:22 <+Steffanx> let me see
2013-09-28T21:26:33 < effractur> from where

2013-09-28T21:28:11 <+Steffanx> it seems to be 11 hours :S
2013-09-28T21:28:16 <+dekar__> OMG
2013-09-28T21:28:22 <+dekar__> and 100€? XD
2013-09-28T21:28:32 < effractur> 60 euros
2013-09-28T21:28:39 <+Steffanx> Euronight train ...
2013-09-28T21:28:40 < effractur> from amsterdam
2013-09-28T21:28:46 <+dekar__> so affordable O.o
2013-09-28T21:29:05 < effractur> and 80 if you want a direct train
2013-09-28T21:29:07 <+dekar__> They'd charge me 100€ to take the train.
2013-09-28T21:29:10 <+Steffanx> effractur goes by train?
2013-09-28T21:29:14 <+Steffanx> i guess not.

2013-09-28T21:47:57 < karlp> I don't see any of those lines going close enough to pick me up!
2013-09-28T21:48:13 <+Steffanx> That's why we need this helicopter karlp
2013-09-28T21:48:32 < karlp> with afro devices for stability control
2013-09-28T21:48:40 < karlp> and all rmeotely controlled by zyp in a norwegian bunker?

2013-09-29T00:17:51 < qyx_> yep
2013-09-29T00:19:00 < Thorn> wtf why are dip switches so expensive
2013-09-29T00:19:04 < zyp> I've given up that
2013-09-29T00:19:47 < qyx_> https://i.imgur.com/sCXLowo.png
2013-09-29T00:19:57 < zyp> there is almost no advantage having them on the board in the first place, and even if you manage to squeeze them in, it doesn't really look good
2013-09-29T00:20:50 < qyx_> if you solder the pcb by hand they are yuite useful
2013-09-29T00:20:59 < qyx_> thats only for a prototype
2013-09-29T00:21:25 < zyp> and what is the point of having it on a different place on the board, when you can just print an assembly drawing that you put beside the board when soldering?
2013-09-29T00:21:46 < qyx_> eh
2013-09-29T00:21:55 < qyx_> ok, maybe that's not optimal
2013-09-29T00:22:55 < zyp> http://bin.jvnv.net/f/SdoRn.png <- that's why I prefer using silk for more useful stuff, like labelling connectors
2013-09-29T00:24:10 < zyp> that said, this board is so simple that I didn't even print an assembly drawing, I just assemled them out of memory
2013-09-29T00:24:35 < zyp> there are only three different kinds of resistors and three different kinds of capacitors, and it's pretty obvious what is what :p

2013-09-29T05:00:50 < emeb_mac> dongs: watching...

2013-09-29T05:05:53 < emeb_mac> Interesting.
2013-09-29T05:06:13 < emeb_mac> Hans Zimmer is well known in my business - has a _lot_ of synthesizer equipment.
2013-09-29T05:06:57 < emeb_mac> http://www.synthgear.com/wp-content/uploads/2010/08/hans_zimmer_studio_4.jpg
2013-09-29T05:07:18 < emeb_mac> all that stuff built into the walls in the back...
2013-09-29T05:10:38 < emeb_mac> patent makes it look like it's just a foam-rubber overlay on a pressure sensor. *yawn*
2013-09-29T05:10:48 < upgrdman> is that hans' home?
2013-09-29T05:11:02 < emeb_mac> I think it's part of his studio.
2013-09-29T05:11:17 < emeb_mac> where he entertains music industry guests
2013-09-29T05:11:49 < emeb_mac> you don't get to do big pictures like "Gladiator" without a bit of schmoozing.
2013-09-29T05:13:10 < upgrdman> too many throw pillow on the couch. i never understood people who do that. it's like you have to throw the pillows somewhere else if you want to sit down
2013-09-29T05:14:20 < dongs> they're supposed to be shared between other couches.
2013-09-29T05:14:22 < emeb_mac> heh
2013-09-29T05:14:52 < emeb_mac> that's for pillow fights of course.
2013-09-29T05:15:37 < emeb_mac> dongs: definitely not "pro" if they're using eagle
2013-09-29T05:17:23 < dongs> at least they seem to have dip opamps in there.
2013-09-29T05:17:27 < dongs> semi-pro
2013-09-29T05:17:47 < emeb_mac> dip makes all the difference
2013-09-29T05:18:03 < emeb_mac> soic or tsop would ruin the sound
2013-09-29T05:18:25 < dongs> BGA will  totally demolish it.
2013-09-29T05:18:31 < dongs> shrinking the soundstage until it becomes negative width.
2013-09-29T05:18:37 < emeb_mac> yep DIP or GTFO
2013-09-29T05:18:59 < emeb_mac> (the irony is strong in this one)
2013-09-29T05:21:28 < upgrdman> anyone know of a good general purpose adhesive for bonding random shit to plastic? i always use shoe goo, or contact cement, with great results, but they take a day to fully set.
2013-09-29T05:28:25 < GargantuaSauce> cyanoacrylate?
2013-09-29T05:28:26 < GargantuaSauce> hot glue?
2013-09-29T05:28:28 < emeb_mac> JB Weld or epoxy?
2013-09-29T05:29:01 < emeb_mac> hot glue is pretty easy to peel off shiny surfaces when it cools
2013-09-29T05:32:37 < dongs> emeb_mac: simple but they want $8888.88 for 88key version.

2013-09-29T05:36:59 < emeb_mac> also allows pitchbend, aftertouch, etc.

2013-09-29T19:03:36 < Thorn> so the best thing I could come up with for mosfet short curcuit protection is 0.01 Ohm shunt + op amp + comparator +  NOR gate
2013-09-29T19:03:47 < Thorn> pretty horrible
2013-09-29T19:04:55 < Guesc> Thorn: buy ONSEMI. they make mosfets with integrated short circuit protection
2013-09-29T19:04:56 < Guesc> :p
2013-09-29T19:05:21 < Thorn> $1+
2013-09-29T19:05:39 < Thorn> (although my circuit probably isn't going to be cheaper)
2013-09-29T19:05:43 < Guesc> http://www.onsemi.com/pub/Collateral/TND394-D.PDF
2013-09-29T19:05:47 < Guesc> ^ sweet
2013-09-29T19:06:05 < Thorn> I've been looking at those (and IRF etc.) yesterday
2013-09-29T19:07:58 < Guesc> I've seen bipolars with multiple emitters. one small one for current sense. maybe someone makes a mosfet with the same principle ?
2013-09-29T19:08:36 < Thorn> I've seen symbols for them in diptrace
2013-09-29T19:08:46 < Thorn> that's all lol.
2013-09-29T19:08:56 < Guesc> I think onsemi makes those too.
2013-09-29T19:11:44 < Guesc> odd. google knows no such device.

2013-09-29T19:19:20 < Thorn> how sensitive are drains of power mosfets to ESD anyway?
2013-09-29T19:20:52 < Guesc> the gate is sensitive. SD is protected by a zener
2013-09-29T19:21:51 < Thorn> in all power mosfets?
2013-09-29T19:22:18 < Guesc> I think so. I think the "zener" is intrinsic to the way the mosfet is constructed.
2013-09-29T19:22:29 < Thorn> the body diode?
2013-09-29T19:22:34 < Guesc> yup
2013-09-29T19:22:46  * Guesc pokes BrainDamage 
2013-09-29T19:22:52 < Guesc> it conducts in both directions
2013-09-29T19:23:00 < Thorn> I'd expect it to blow up if the body diode breaks down
2013-09-29T19:23:30 < Thorn> (but maybe not from esd as total energy is small)
2013-09-29T19:23:32 < BrainDamage> yes there's mosfets with current reading capability
2013-09-29T19:23:50 < BrainDamage> with multiple sources or even multiple gates
2013-09-29T19:23:51 < BrainDamage> but they are rare
2013-09-29T19:24:15 < BrainDamage> the body diode is a normal diode, not a zener
2013-09-29T19:24:29 < BrainDamage> and yes it's intrinsec in how it's made of
2013-09-29T19:24:31 < Guesc> so in mosfets like the IRFP240 - the zener is intentionally  constructed ?
2013-09-29T19:24:55 < BrainDamage> yes, in some cases they either put an explicit separate junction
2013-09-29T19:25:15 < BrainDamage> or modify the mosfet so that it behaves like a zener when the diode breaks down
2013-09-29T19:25:27 < BrainDamage> so it can sustain the breakdown withot avalanche effects
2013-09-29T19:25:28 < gxti> "guaranteed to withstand a specified level of energy in the breakdown avalanche mode of operation"
2013-09-29T19:26:11 < BrainDamage> that's for any devices ^, if you stay within x energy, the avalanche won't break it
2013-09-29T19:26:26 < BrainDamage> the difference is that for some, they specify you how much x is
2013-09-29T19:26:55 < gxti> i think all mosfet symbols that show the body diode use the zener symbol just to remind you it has a breakdown voltage
2013-09-29T19:27:39 < emeb_mac> the phrase for today comes from spacex - "Awaiting Vehicle Downlink"
2013-09-29T19:28:05 < gxti> but ultimately zener diodes are just normal diodes with a characterized reverse voltage, not like they're completely different devices

2013-09-29T19:29:27 < gxti> he probably used some 'real pro' software and now it's all fucked
2013-09-29T19:30:24 < BrainDamage> gxti: no, not normal diodes
2013-09-29T19:30:37 < BrainDamage> normal diodes are typically weakly doped, to gain speed
2013-09-29T19:30:45 < gxti> sure, doped differently
2013-09-29T19:31:01 < BrainDamage> zener go the other way, doped so heavily that the electric field makes electron tunnel trough the junction
2013-09-29T19:31:05 < BrainDamage> there's no avalanche
2013-09-29T19:31:27 < BrainDamage> they tunnel trough the energy gap of the bands bent from the E-field
2013-09-29T19:31:57 < gxti> and zeners below 6v and above 6v operate by different mechanisms too
2013-09-29T19:32:26 < BrainDamage> sure - that too
2013-09-29T19:32:32 < gxti> but which of those things does the body diode of a mosfet look most like?

2013-09-29T19:33:47 < BrainDamage> normal diode typically
2013-09-29T19:34:04 < BrainDamage> and in some cases, as I said, they even put an external extra junction
2013-09-29T19:34:13 < BrainDamage> or dope a section of the drain
2013-09-29T19:34:19 < BrainDamage> using a zener profile
2013-09-29T19:34:32 < BrainDamage> if you don't go for the effect, it's a normal avalanche

2013-09-30T03:29:42 < Thorn> does "logic level mosfet" always == "you can directly drive it from a mcu pin"? I mean peak current due to gate capacitance

2013-09-30T03:39:03 < zyp> level = voltage level, i.e. v_gs
2013-09-30T03:39:46 < zyp> in other words, it has a v_gs threshold low enough to be driven by a logic level signal
2013-09-30T03:41:21 < dongs> doesn't mean it'll be good at it tho
2013-09-30T03:41:48 < zyp> true
2013-09-30T03:43:03 < ohsix> being arbitrarily slow is probably something to think of
2013-09-30T03:44:46 < Thorn> you can always add a series resistor to limit current but then you hava a time constant and the mosfet is in linear region for some time -> heat
2013-09-30T03:46:07 < dongs> heh, the problem isnt limiting it
2013-09-30T03:46:31 < dongs> its the reverse, that STM can't  source a lot of current per pin to switch it quickly
2013-09-30T03:46:45 < dongs> i mean if youre just toggling a led at 1Hz it probly doesnt matter
2013-09-30T03:47:16 < Thorn> I'm talking pwm at ~50kHz
2013-09-30T03:47:25 < dongs> forget it
2013-09-30T03:47:29 < Thorn> well maybe a few kHz
2013-09-30T03:47:38 < dongs> use a driver
2013-09-30T03:48:46 < ohsix> what's it for?
2013-09-30T03:53:28 < Thorn> well. 50kHz is way too much, maybe <1kHz. it's for led lighting

2013-09-30T05:45:29 < R2COM> hi
2013-09-30T05:45:34 < R2COM> whats donging?
2013-09-30T05:48:56 < R2COM> 1 point to the one who can find something unusual here
2013-09-30T05:48:58 < R2COM> http://i.imgur.com/xggsf46.jpg
2013-09-30T05:50:04 < ohsix> the bodies of the resistor arrays are touching?
2013-09-30T05:50:16 < R2COM> yes
2013-09-30T05:50:23 < R2COM> thats why I had to put one of them above others
2013-09-30T05:50:26 < R2COM> and solder manully
2013-09-30T05:50:30 < ohsix> nice
2013-09-30T05:50:46 < R2COM> not sure why is that, I made appropriate footprint border, but resistors came bigger
2013-09-30T05:50:51 < R2COM> not a big deal
2013-09-30T05:50:51 < ohsix> i bet i would have missed that too
2013-09-30T05:50:59 < R2COM> although took some time to manually solder like that
2013-09-30T05:51:38 < R2COM> also
2013-09-30T05:51:46 < R2COM> I'm fucking tired of soldering stm32 package in a wrong way
2013-09-30T05:51:50 < R2COM> because of that fucking two dots
2013-09-30T05:51:53 < R2COM> which always confuse me
2013-09-30T05:51:56 < R2COM> did it again now
2013-09-30T05:52:05 < R2COM> had to remove with hot air, and resolder in a right way with iron manually
2013-09-30T05:52:11 < ohsix> pin 1 is the big one right?
2013-09-30T05:52:14 < R2COM> what an idiots
2013-09-30T05:52:14 < dongs> no
2013-09-30T05:52:16 < dongs> small one
2013-09-30T05:52:22 < ohsix> niiice
2013-09-30T05:52:22 < dongs> pin1 is the concave one
2013-09-30T05:52:24 < dongs> the big one is flat
2013-09-30T05:52:29 < dongs> and is something else.
2013-09-30T05:52:31 < ohsix> ohh
2013-09-30T05:52:33 < R2COM> I mean theres Xilkinx chip near it...see has one dot
2013-09-30T05:52:37 < R2COM> why the fuck put two dots
2013-09-30T05:52:39 < R2COM> big small...
2013-09-30T05:52:40 < ohsix> from package registration probably
2013-09-30T05:52:44 < R2COM> then create possibility for error
2013-09-30T05:52:53 < ohsix> they don't put two, they added one :p
2013-09-30T05:53:15 < dongs> prettt sure we've been through this
2013-09-30T05:53:22 < dongs> datasheet covers the hole position + index hole
2013-09-30T05:53:39 < R2COM> I know that
2013-09-30T05:53:39 < dongs> also its bottom left of writing when looking at it correctly
2013-09-30T05:53:46 < R2COM> I am just saying why the fuck to do that
2013-09-30T05:53:48 < dongs> so that one's also pretty obvious
2013-09-30T05:54:06 < R2COM> chip on the right...I never can put it wrong
2013-09-30T05:54:12 < R2COM> even if I'm drunk
2013-09-30T05:54:15 < ohsix> usually the size matters, it's plausible they'd use that to disambiguate it

2013-09-30T09:40:17 < dongs> worse: if I try typing into that GOOGLE SEARCH BOX in teh fucking center of the page, it just jumps right back to address bar
2013-09-30T09:40:26 < R2COM> I have up to date google chrome
2013-09-30T09:40:27 < dongs> so it serves no fucking purpose other than to lag my internet.

2013-09-30T09:43:12 < R2COM> dont see any anomaly
2013-09-30T09:44:11 < R2COM> maybe your pc has some virus
2013-09-30T09:44:14 < dongs> Users who want to restore the previous design should type "chrome://flags" in the omnibox -- minus the quotation marks -- locate the "Enable Instant Extended API" setting in the long list, and change it from "Enable" to "Disable."
2013-09-30T09:44:18 < dongs> ohhh
2013-09-30T09:44:23 < R2COM> or some cool hacker is dicking around with your pc

2013-09-30T09:46:28 < R2COM> with some recently visited pages
2013-09-30T09:46:29 < dongs> thats the problem.
2013-09-30T09:46:30 < R2COM> and search bar
2013-09-30T09:46:32 < dongs> yes.
2013-09-30T09:46:35 < R2COM> but I use top bar as search bar
2013-09-30T09:46:48 < R2COM> why is it problem?
2013-09-30T09:46:53 < R2COM> what do you want to see in the center?
2013-09-30T09:47:11 < dongs> R2COM: it pulls that shit from internet
2013-09-30T09:47:14 < dongs> not local
2013-09-30T09:47:17 < ohsix> THE
2013-09-30T09:47:17 < emeb_mac_> just the frequently visited pages
2013-09-30T09:47:19 < ohsix> INTERNET
2013-09-30T09:47:21 < dongs> so opening new page = it does few kbytes of requests
2013-09-30T09:47:26 < dongs> to check google spam shit
2013-09-30T09:47:27 < dongs> i dont want that
2013-09-30T09:47:31 < ohsix> that's why it says waiting on cache when you open it
2013-09-30T09:47:35 < R2COM> lol
2013-09-30T09:47:47 < R2COM> I forgot that your are at dial up internet..and its a problem for you
2013-09-30T09:47:59 < ohsix> he can't even stay connected to freenode
2013-09-30T09:49:16 < R2COM> ok I removed it too anyhow
2013-09-30T09:50:03 < R2COM> whats google drive shit?
2013-09-30T09:50:08 < R2COM> online storage?
2013-09-30T09:50:17 < R2COM> is it reliable?
2013-09-30T09:50:29 < dongs> i wouldnt store cp in it
2013-09-30T09:50:42 < R2COM> why
2013-09-30T09:50:53 < dongs> because NSA has all the files on it.
2013-09-30T09:51:19 < R2COM> well that makes you more secure
2013-09-30T09:51:50 < R2COM> so 15GB
2013-09-30T09:52:06 < R2COM> I could put all the trash I share here just there maybe instead of imgur every time
2013-09-30T09:52:21 < dongs> 15gb shared with t he rest of your google services.
2013-09-30T09:52:27 < dongs> so if your inbox is 8gigs you get less.
2013-09-30T09:53:27 < R2COM> 100GB 5$ months
2013-09-30T09:54:09 < ohsix> drive is cool
2013-09-30T09:54:21 < R2COM> why
2013-09-30T09:54:27 < ohsix> just handy
2013-09-30T09:54:42 < ohsix> y ou can have acl's for people with google accounts and there's online editing
2013-09-30T09:55:16 < R2COM> google might make a google laptop
2013-09-30T09:55:21 < R2COM> which doesnt have HDD
2013-09-30T09:55:26 < R2COM> just internet connection
2013-09-30T09:55:38 < R2COM> so you buy it, and there you go.. 100GB free for example
2013-09-30T09:55:43 < R2COM> and makes laptop lighter
2013-09-30T09:55:46 < ohsix> might?
2013-09-30T09:55:47 < R2COM> :)
2013-09-30T09:56:12 < R2COM> lol
2013-09-30T09:56:38 < R2COM> oh
2013-09-30T09:56:42 < R2COM> and OS would be online too
2013-09-30T09:56:46 < R2COM> and always loaded!
2013-09-30T09:56:52 < R2COM> hm no wait
2013-09-30T09:57:14 < R2COM> after bootup, laptop immediately gets data from online drive to ram
2013-09-30T09:57:17 < R2COM> and thats it
2013-09-30T09:57:27 < R2COM> or even better

2013-09-30T09:57:39 < R2COM> RAM image of actively running laptop is online too

2013-09-30T09:58:05 < R2COM> which makes boot process super fast
2013-09-30T09:59:10 < R2COM> then some hacker hacks it, and accesses everyones pc
2013-09-30T09:59:11 < R2COM> :)
2013-09-30T09:59:50 < dongs> 15:55 < R2COM> google might make a google laptop

2013-09-30T09:59:51 < dongs> 15:55 < R2COM> just internet connection

2013-09-30T10:00:25 < dongs> the rest is just opening chrome fullscreen
2013-09-30T10:01:13 < dongs> thats y i was gonna buy chromebook dixel
2013-09-30T10:01:20 < dongs> then I read up and saw you cant run anything except chrome on it
2013-09-30T10:01:24 < dongs> so it'd be a hueg waste
2013-09-30T10:01:29 < ohsix> not true
2013-09-30T10:01:32 < dongs> so i bought just the screen instead
2013-09-30T10:01:46 < ohsix> you do have to wipe out the os for it, then you can install loonix
2013-09-30T10:01:54 < dongs> not what i would want to do.
2013-09-30T10:02:01 < R2COM> lol

2013-09-30T10:02:21 < R2COM> so you cant run any app?
2013-09-30T10:02:27 < R2COM> is it laptop for internet browsing only?

2013-09-30T10:02:44 < dongs> store all the crap in cloud
2013-09-30T10:02:51 < dongs> there's no local storage except cache
2013-09-30T10:03:01 < dongs> it is fucking dum
2013-09-30T10:03:08 < R2COM> and cant run office?
2013-09-30T10:03:17 < dongs> chromebook = lunix
2013-09-30T10:03:18 < dongs> so no.

2013-09-30T10:12:04 < R2COM> just for lolz
2013-09-30T10:12:25 < R2COM> I had a feeling people didnt work that hard there
2013-09-30T10:12:39 < R2COM> they had Gym and recreational rooms etc all over inside offices
2013-09-30T10:13:04 < R2COM> I was like ....wtf.. isnt it a work place and during a day people supposed to work
2013-09-30T10:14:30 < ohsix> if you go to the gym and shit already, sure is nice having them at work amirite
2013-09-30T10:14:49 < R2COM> nah
2013-09-30T10:15:12 < R2COM> during day energy of people needs to be concentrated on work
2013-09-30T10:15:59 < jpa-> most people work more efficiently if they can have some breaks and/or exercise during the day
2013-09-30T10:16:28 < ohsix> how long do you think people can spend their useful energy and focus on work?
2013-09-30T10:16:29 < jpa-> sitting 8 hours straight makes you tired and adds to back problems
2013-09-30T10:16:40 < ohsix> makes you shit at what you do, too
2013-09-30T10:20:35 < R2COM> its not straight 8 hours
2013-09-30T10:20:44 < R2COM> 1 hour break inbetween
2013-09-30T10:20:51 < R2COM> 4 + 4 hours
2013-09-30T10:20:55 < R2COM> makes it ok
2013-09-30T10:21:38 < R2COM> 4+4+4 even better
2013-09-30T10:21:49 < jpa-> and during that 1 hour, wouldn't it be great if you could first go to gym for 15 mins, take a shower, go eat for 30 min and then resume work?
2013-09-30T10:22:27 < R2COM> shower for 5 mins then?
2013-09-30T10:22:34 < R2COM> 5 min to change from work clothes to gym clothes
2013-09-30T10:22:37 < R2COM> 15 for gym
2013-09-30T10:22:41 < R2COM> 5 min shower
2013-09-30T10:22:44 < jpa-> yeah, would work
2013-09-30T10:22:44 < R2COM> 5 min to change clothes back
2013-09-30T10:22:49 < R2COM> 25 min eating
2013-09-30T10:22:54 < R2COM> 5 min prepare back for work
2013-09-30T10:23:11 < R2COM> I could do that.
2013-09-30T10:23:12 < R2COM> but
2013-09-30T10:23:27 < R2COM> according to what I saw there...and at the "speed" at which those guys there moved
2013-09-30T10:23:27 < jpa-> though around here you can freely decide the length of the lunch break, as long as it is atleast the minimum 30 minutes
2013-09-30T10:23:29 < R2COM> and did stuff
2013-09-30T10:23:39 < R2COM> I have a high doubt they did all that for the time constraints specified above
2013-09-30T10:23:41 < R2COM> lol
2013-09-30T10:23:51 < jpa-> ah, so you are saying that google is doing so very poorly because their workers are lazy?
2013-09-30T10:24:13 < R2COM> who said that google doing poorly?
2013-09-30T10:24:26 < jpa-> so who cares if they are (or appear) lazy :P
2013-09-30T10:24:45 < R2COM> ceo probably should dunno
2013-09-30T10:24:57 < R2COM> or maybe he doesnt
2013-09-30T10:25:05 < R2COM> maybe they have other people in other locations doing real job
2013-09-30T10:25:21 < R2COM> and those in headquarters are friends/relatives of ceo or something and just have a nice position for free
2013-09-30T10:26:00 < jpa-> maybe they work smart, not hard? ;)
2013-09-30T10:26:23 < R2COM> then I just failed to recognize their smartness
2013-09-30T10:26:33 < R2COM> must have been too smart then
2013-09-30T10:28:16 < ohsix> gotta consider what type of work they're doing, it's mostly creative work
2013-09-30T10:28:28 < R2COM> freejob
2013-09-30T10:29:24 < R2COM> it kinda looked to me it was mostly social like atmosphere there
2013-09-30T10:29:41 < R2COM> some people around in conferences rooms, talks etc etc
2013-09-30T10:29:46 < R2COM> social crap
2013-09-30T10:30:21 < ohsix> heh
2013-09-30T10:30:24 < R2COM> in other words - laying off half of them all, and nothing would hurt a company :)
2013-09-30T10:30:44 < ohsix> i think you misunderstand what type of job people have at google
2013-09-30T10:30:59 < dongs> isnt google jobs = holding dicks
2013-09-30T10:31:29 < R2COM> it mostly is, just some dude here argues

2013-09-30T11:01:25 < R2COM> by sinusoid
2013-09-30T11:01:26 < R2COM> ?

2013-09-30T11:07:46 < R2COM> and with ideal components only?
2013-09-30T11:08:21 < R2COM> or you going to simulate it later on some legit simulator with precise models for each passive?
2013-09-30T11:08:33 < Robint91> R2COM, nope, running simulations with legit models
2013-09-30T11:08:44 < Robint91> R2COM, but the problem is that most models are shit
2013-09-30T11:09:12 < R2COM> hm. they are not.
2013-09-30T11:09:45 < Robint91> R2COM, I would use some GaAs schotty diodes
2013-09-30T11:10:00 < Robint91> but they don't have a good spice model
2013-09-30T11:13:08 < R2COM> so
2013-09-30T11:13:12 < R2COM> what type of schottky you need
2013-09-30T11:13:42 < Robint91> R2COM, some very high speed, low capitace schottky. But I already found some
2013-09-30T11:13:50 < R2COM> with models?
2013-09-30T11:14:07 < R2COM> look at HSMS-286
2013-09-30T11:14:09 < R2COM> from avago
2013-09-30T11:14:16 < R2COM> they have s-parameters and Spice models too

2013-09-30T11:15:02  * Robint91 does more transient simuations
2013-09-30T11:15:15 < Robint91> so I can't do much with s-parameters
2013-09-30T11:16:04 < R2COM> what exactly you are building?
2013-09-30T11:16:29 < Robint91> I need to build a system that distobutes a sync pulse and a steady clock
2013-09-30T11:16:33 < Robint91> at 1GHz
2013-09-30T11:16:57 < Robint91> the problem is that the aligment of the pulse need to be done exactly as possible
2013-09-30T11:17:24 < dongs> youre gonna build a ghz system using 1N1418??
2013-09-30T11:17:27 < Robint91> use two seperate cable gives you run length differences
2013-09-30T11:17:47 < Robint91> dongs, nope, but I'm going to do that with the HSMS-286
2013-09-30T11:18:09 < dongs> that looks slightly more legit
2013-09-30T11:18:30 < Robint91> dongs, first test princple with ltspice, if that works -> move to design frequency with accurate models

2013-09-30T11:20:13 < R2COM> sync pulse can be anywhere within that limit?
2013-09-30T11:20:14 < R2COM> or what
2013-09-30T11:20:53 < R2COM> ah
2013-09-30T11:20:54 < Robint91> I want that the sync pulse as enough BW so that I can send it over 1 periode of the clock

2013-09-30T11:21:54 < Robint91> R2COM, nice short rise and fall times == no setup and hold time problems == happy me
2013-09-30T11:22:24 < R2COM> how about group delay caused by filters
2013-09-30T11:22:54 < R2COM> ?
2013-09-30T11:22:59 < Robint91> that is deterministical -> I don't really care
2013-09-30T11:23:07 < ohsix> how about an easier clock to move around and some plls
2013-09-30T11:23:34 < Robint91> ohsix, phase noise will be come to high
2013-09-30T11:23:41 < Robint91> that 1GHz is driving a PLL also
2013-09-30T11:24:19 < ohsix> it would be easier to control than changing cable lengths ;D
2013-09-30T11:27:28 < R2COM> so
2013-09-30T11:27:44 < R2COM> its part of a system responsible for something like clock distribution
2013-09-30T11:27:49 < R2COM> clock and sync pulse
2013-09-30T11:28:12 < R2COM> hm
2013-09-30T11:28:16 < Robint91> ohsix, you need cable with the exactly electrical lenght
2013-09-30T11:28:36 < Robint91> ^ which is hard to do for "large distances"
2013-09-30T11:28:43 < R2COM> ah
2013-09-30T11:28:45 < R2COM> large distance
2013-09-30T11:28:54 < Robint91> the sync pulse triggers some AD converters
2013-09-30T11:29:10 < R2COM> :)
2013-09-30T11:29:14 < Robint91> with sample at 3GSPS and dump that in some ram
2013-09-30T11:31:00 < R2COM> basically
2013-09-30T11:31:14 < R2COM> the idea here is to have all parts of system fed with precisely aligned clocks?
2013-09-30T11:31:43 < R2COM> and some of parts needs to have carefully shifted clocks with respect to main one
2013-09-30T11:31:44 -!- Nutter` is now known as Nutter
2013-09-30T11:31:49 < R2COM> and you build a distribution system for it
2013-09-30T11:31:51 < R2COM> ?
2013-09-30T11:33:19 < Robint91> R2COM, precise aligned clocks aren't needed
2013-09-30T11:33:43 < Robint91> but all the systems need to be started at the same clock pulse
2013-09-30T11:34:13 < R2COM> so the shit you are designing now going to be better than say something like AD9525 >
2013-09-30T11:34:13 < R2COM> ?
2013-09-30T11:34:13 < Robint91> no matter if the clock pulse and sync need to travel 1ns longer
2013-09-30T11:34:43 < Robint91> because we know all AD converters started at the same time
2013-09-30T11:35:13 < Robint91> and has some offset values that we can remove with some simple calibration
2013-09-30T11:35:23 < R2COM> why not use something like AD9525 ?
2013-09-30T11:35:34 < R2COM> it was designed for exactly stuff you described now
2013-09-30T11:36:30 < Robint91> no, out sync signal is modulated on the clock signal
2013-09-30T11:36:49 < Robint91> so we know that the sync and clock have the same cable delay
2013-09-30T11:37:43 < R2COM> so
2013-09-30T11:37:59 < R2COM> you mean, you want it to be modulated on the clock signal right?
2013-09-30T11:38:21 < Robint91> yep
2013-09-30T11:38:50 < Robint91> I have ideas how to design the modulator
2013-09-30T11:39:49 < R2COM> did you know about that ad9525 i mentioned?
2013-09-30T11:40:02 < R2COM> it has capability to derive sync_out from base reference clock
2013-09-30T11:40:22 < R2COM> and 16bit divider allows you to divide it
2013-09-30T11:40:30 < Robint91> R2COM, yep, it is nothing special, it doens't do the modulating of the clock
2013-09-30T11:42:08  * Robint91 heads back to desiging a 60GHz clock system

2013-09-30T15:48:10 < zyp> ah, right
2013-09-30T15:48:16 < zyp> it's just that estimate said tuesday
2013-09-30T15:48:27 < dongs> oh, those are never right

2013-09-30T15:49:20 < Posterdati> zyp: it seems that reusing transfers is for interrupt mode only
2013-09-30T15:52:09 < dongs> http://i.imgur.com/zZjdfp7.jpg
2013-09-30T15:53:42 < zyp> Posterdati, it doesn't say "only"
2013-09-30T15:53:44 <+Steffanx> Wonderful.
2013-09-30T15:53:54 < zyp> as I read it, resubmission should be fine
2013-09-30T15:54:10 < zyp> but remember that you at least have to allocate two
2013-09-30T15:54:53 < zyp> you can't resubmit it before it completes, so you want to allocate another to submit after the first
2013-09-30T15:57:04 < Posterdati> zyp: I used to allocate 4
2013-09-30T15:57:23 < Posterdati> zyp: then wait until 2 are competed
2013-09-30T15:59:57 < zyp> http://paste.jvnv.net/view/1n7q1 <- here's my stuff, usb code starts on line 143
2013-09-30T16:00:39 < zyp> 167 allocates a transfer, 168 configures it, 169 submits it
2013-09-30T16:01:08 < zyp> this is isochronous, not bulk, but I used the same code for bulk previously
2013-09-30T16:01:30 < zyp> 171 is the callback, which then resubmits the transfer on line 196
2013-09-30T16:01:57 < zyp> and initially two transfers are scheduled by lines 163 and 164
2013-09-30T16:02:30 < Posterdati> so you don't queue transfers, you allways wait for the submitted to complete
2013-09-30T16:02:44 < zyp> no
2013-09-30T16:03:08 < zyp> I initially submit two transfers, that way I always have one queued
2013-09-30T16:03:50 < zyp> once the first completes, the queued one will take over, then when I've finished processing the first, it's resubmitted and queued after the second one
2013-09-30T16:03:50 < Posterdati> ah ok, you always wait for only one to complete
2013-09-30T16:04:18 < Posterdati> at every completion you feed the queue with a new transfer
2013-09-30T16:04:34 < zyp> yes
2013-09-30T16:05:03 < Posterdati> good
2013-09-30T16:05:05 < Posterdati> thanks
2013-09-30T16:05:17 < Posterdati> I submitted 4 and wait for almost two to complete
2013-09-30T16:05:28 < zyp> I'm using isochronous because I have no buffer on the device side, but only a data rate of 400 packets per second
2013-09-30T16:05:49 < zyp> and my code is able to keep up without dropping lots of packets
2013-09-30T16:06:03 < Posterdati> ok
2013-09-30T16:06:13 < Posterdati> but I can't loose packet so I need to buffer them
2013-09-30T16:16:04 < Thorn> https://www.sparkfun.com/products/10256 is there really a market for this
2013-09-30T16:16:55 <+Steffanx> I guess for those few who dont want to use some prototype board stuff
