2014-12-01T03:47:01 < dongs> my $100 offer got rejected
2014-12-01T03:47:38 < dongs> Sorry, nyctesttech has turned down your offer of US $100.00. Make another offer before the item ends.
2014-12-01T03:49:47 < dongs> i might re-offer for $100.01
2014-12-01T03:49:52 < dongs> did you see what it was?
2014-12-01T03:50:00 < dongs> http://www.ebay.com/itm/271673317985
2014-12-01T03:50:01 < dongs> check i tout
2014-12-01T03:50:25 < dongs> read the description
2014-12-01T03:50:40 < dongs> its missing the actual scope part
2014-12-01T03:50:50 < dongs> < dongs> Note:Since this is missing all the actual "scope" parts, $100 is the best I can offer. Maybe I'll reuse the keyboard matrix and LCD with an arduino to make it some kinda home automation controller.
2014-12-01T03:50:59 < dongs> ^ this is what was in my $100 offer

2014-12-01T03:51:33 < dongs> thats ridiculous
2014-12-01T03:51:58 < zyp> is it even worth $100? :p
2014-12-01T03:52:27 < dongs> nope
2014-12-01T03:54:40 < zyp> stop being so slow
2014-12-01T03:56:37 < dongs> raid1 mabye?
2014-12-01T03:56:41 < dongs> for raid6 y ou need minimum 4drives

2014-12-01T03:57:04 < dongs> yeah
2014-12-01T03:57:34 < dongs> eha
2014-12-01T03:59:39 < dongs> i wanna get chinks to make a dual NGFF > USB3 raid1 enclosure
2014-12-01T03:59:43 < dongs> in size of 2.5" hdd
2014-12-01T03:59:51 < dongs> there exist dual ngff>2.5 sata form shits
2014-12-01T04:00:01 < dongs> this should be trivial to replace with a usb3 raid1 chip
2014-12-01T04:00:06 < dongs> i dont wanna make that shit myself
2014-12-01T04:00:36 < zyp> ngff?
2014-12-01T04:00:39 < zyp> is that same as m.2?
2014-12-01T04:00:39 < dongs> ssd raid in usable form factor
2014-12-01T04:00:43 < dongs> zyp: yea
2014-12-01T04:00:46 < dongs> shorter, generally
2014-12-01T04:00:48 < zyp> ah
2014-12-01T04:00:54 < dongs> but spec allows for some variable lengths
2014-12-01T04:01:35 < zyp> hmm, is that still sata signalling like msata?
2014-12-01T04:01:40 < dongs> yes
2014-12-01T04:02:02 < zyp> why usb3?
2014-12-01T04:02:06 < dongs> portable

2014-12-01T04:02:36 < dongs> basically i want this but with usb3 raid instead of sata
2014-12-01T04:02:45 < dongs> so form factor is definitely possible
2014-12-01T04:03:09 < zyp> buy that and stick it in a usb3 enclosure? :p
2014-12-01T04:03:14 < dongs> too much work
2014-12-01T04:03:28 < dongs> usb3 enclosures are ugly
2014-12-01T04:05:06 < qyx_> buy 2 usb3 keys

2014-12-01T06:58:58 < yan_> anyone know how having a HSE oscillator influences power consumption? datasheet says .5mA when stable, but does that include components, or just the MCU consumption?
2014-12-01T06:59:45 < dongs> yes
2014-12-01T07:00:09 < dongs> obv HSE will use some power to run the oscillator circuit
2014-12-01T07:00:18 < dongs> im guessing 0.5 is for that
2014-12-01T07:00:29 < dongs> what "include components"?
2014-12-01T07:00:54 < yan_> i meant whether or not the 0.5 includes the power required to run the oscillator. in retrospect, not sure what else that could mean

2014-12-01T07:06:28 < yan_> i guess along similar lines, if i'm using a 16mhz oscillator for something like usb, do i need to get another 32.768 crystal if i want accurate RTC?

2014-12-01T07:09:59 < yan_> dongs: but obviously, if LSI is sufficient, i can just use that for RTC and the HSE for USB
2014-12-01T07:10:17 < dongs> sure
2014-12-01T07:10:23 < dongs> datasheet mentions accuracy
2014-12-01T07:10:26 < dongs> if you can deal with that, no problem
2014-12-01T07:11:39 < yan_> dongs: hmm been looking in the datasheet for rtc accuracy of PLL+LSI, but didn't see it
2014-12-01T07:11:53 < yan_> looking at STM32L15xx6 datasheet
2014-12-01T07:12:05 < zyp> PLL shouldn't affect accuracy

2014-12-01T10:55:32 < jpa-> check the schematic?

2014-12-01T13:46:38 < zyp> HS raises the interrupt endpoint limitations, allowing an increase in poll rate from 1000Hz to 8000Hz
2014-12-01T13:46:56 < zyp> and probably larger reports than 64B as well, I don't remember HS limit on interrupt MPS
2014-12-01T13:59:38 < dongs> zyp, is that due to 125us or wahtever frame stuff?
2014-12-01T13:59:45 < zyp> yes
2014-12-01T14:00:08 < dongs> so stm32 cant do  > 1khz polling right?
2014-12-01T14:00:10 < dongs> cuz its 2.0hs
2014-12-01T14:00:11 < zyp> 8 microframes per traditional frame, one transfer per microframe
2014-12-01T14:00:20 < dongs> err, cuz its NOT
2014-12-01T14:00:30 < zyp> correct, FS is limited to 1khz

2014-12-01T14:04:05 < zyp> also, usb2.0 encompasses both LS, FS and HS, so it's not an accurate term for speeds

2014-12-01T14:05:32 < dongs> zyp, right, but which part on stm32 makes it classify as 2.0
2014-12-01T14:05:35 < dongs> as opposed t o1.1
2014-12-01T14:05:51 < zyp> your question doesn't make sense
2014-12-01T14:05:58 < zyp> say HS if that's what you mean
2014-12-01T14:06:03 < dongs> no
2014-12-01T14:06:14 < dongs> on F1 there's no HS
2014-12-01T14:06:34 < zyp> F1 supports FS only
2014-12-01T14:06:37 < dongs> right
2014-12-01T14:06:43 < zyp> i.e. 12 Mb/s
2014-12-01T14:06:47 < dongs> so what makes it 2.0FS as opposed to 1.1
2014-12-01T14:06:57 < dongs> other htan the name
2014-12-01T14:07:03 < zyp> bcdUSB in the device descriptor saying 2.0 and not 1.1

2014-12-01T14:54:37 < rewolff1> So hosts and devices were forced to call themselves "2.0" even when they didn't support 480mbps (hi speed).

2014-12-01T15:31:00 < xata> dongs: well, usually when you connect i2c it includes two lines - clock (scl) and data (sda), but you can't just connect two devices over i2c, you need a resistor to vcc so i2c could be pushed. also there is another way involving 74*07 standart logic. but as it is just a buffer, it is one-directional. and data line is bidirectional unlike clock line. and you can not just connect two inverted buffers - it will
2014-12-01T15:31:06 < xata>  be a loop.
2014-12-01T15:31:28 < dongs> xata: if your goal is level conversion, there are several devices to do this bidirectionally

2014-12-01T16:17:49 < decimad2_> is it sane to assume that every exception will end up in the flash wait states if the vector table is in flash? And onether run of waitstates if the ISR is in flash?
2014-12-01T16:19:06 < karlp> "flash wait states" ?
2014-12-01T16:19:24 < decimad2_> Yeah, the 5 wait states you have when running at 168MHz f.e.
2014-12-01T16:19:32 < karlp> that's nothing to do with exceptions
2014-12-01T16:19:51 < xata> dongs: fxma2102 is a good advice, thanks
2014-12-01T16:20:01 < decimad2_> I'm citing the word "exception" from the cortex-m4 technical manual
2014-12-01T16:21:47 < decimad2_> My understanding is, that means interrupt from the nvic, execution exception from m4 itself and software exceptions like svc?
2014-12-01T16:22:02 < karlp> what are you talking about?
2014-12-01T16:22:27 < karlp> exceptions are just code
2014-12-01T16:23:02 < karlp> if your exception handler is in flash, it' sjust like any other code in flash...
2014-12-01T16:24:33 < decimad2_> The thing I am unsure about is, if the flash controller is caching the vector table and maybe the first few words pointet to by table entries
2014-12-01T16:26:07 < karlp> have you ever read anything even hinting at that?
2014-12-01T16:26:35 < decimad2_> I have read that the flash controller is caching *some* stuff, but I don't know the scheme.

2014-12-01T16:34:07 < decimad2_> And what does the "what are you talking about?" question mean exactly? And what do you mean by "exceptions are just code"? I mean an external interrupt is not "just code" to me. In the end it boils down to reading the vector table, stacking registers, and branching to ISR. At least if I get the terms correctly.

So I cannot get "bounded" interrupt latencies if I have the table or the ISRs in flash. Would that be a correct interpretation of the given informations?

2014-12-01T16:54:28 < Thorn> interrupts are events on IRQ lines that are connected to the NVIC. these (possibly) cause exceptions in the core (i.e. state is pushed onto the stack, control is passed to a handler)

2014-12-01T17:38:32 < decimad2_> gxti: you mean the latency thingy? I guess if timing is critical, you must make worst case considerations. If no upper boundary is specified, then it's unusable (until you contact them to clarify, I guess)
2014-12-01T17:38:34 < gxti> compare interrupt latency of flash vs ram, or even with irq table in ram and code in flash

2014-12-01T18:29:00 < Tekkkz> hello guys
2014-12-01T18:30:18 < brabo> hi Tekkkz
2014-12-01T18:30:27 < Tekkkz> hi, btw all works right now
2014-12-01T18:30:39 < Tekkkz> my linker script was full with mistakes
2014-12-01T18:30:40 < brabo> great!
2014-12-01T18:30:43 < brabo> aha
2014-12-01T18:30:49 < Tekkkz> but i have a problem, let me explain
2014-12-01T18:30:57 < brabo> ye, idk enough about the nitty gritty of that
2014-12-01T18:31:02 < brabo> sure..
2014-12-01T18:31:38 < Tekkkz> i want to get the voltage on an adc pin, so i read it out what works well BUT the calculation from the value to the voltage dont work: my console output:
2014-12-01T18:31:40 < Tekkkz> value:4092    voltage:0.000000
2014-12-01T18:31:45 < Tekkkz> at 3V
2014-12-01T18:31:52 < Tekkkz> uint16_t adc_wert;
2014-12-01T18:31:54 < Tekkkz>   volatile float p;
2014-12-01T18:31:59 < Tekkkz> p=(adc_wert/4096)*3;
2014-12-01T18:32:05 < Tekkkz> why is p=0.000000
2014-12-01T18:32:07 < Tekkkz> ?
2014-12-01T18:32:15 < Tekkkz> and not the right value?
2014-12-01T18:32:22 < gxti> take a guess
2014-12-01T18:32:28 < gxti> and i'll tell you if you're right.
2014-12-01T18:32:30 < Tekkkz> i think
2014-12-01T18:32:38 < Tekkkz> it has something to do with the data types?

2014-12-01T18:32:42 < gxti> yep.
2014-12-01T18:32:46 < Tekkkz> oh well
2014-12-01T18:32:53 < Tekkkz> bt now i must know what excatly :D
2014-12-01T18:32:54 < brabo> ah
2014-12-01T18:33:01 < brabo> i think i may know
2014-12-01T18:33:10 < Tekkkz> yeah?
2014-12-01T18:33:24 < brabo> isnt this 0-5000 mV? and substract 2500 and you have the real value?
2014-12-01T18:33:56 < gxti> no, it's not that
2014-12-01T18:34:00 < Tekkkz> no, reference is 3V, but this is not the mistake, the mistake is at the calculation
2014-12-01T18:34:00 < brabo> ah
2014-12-01T18:34:11 < Tekkkz> i can use a uint16 at this, right?
2014-12-01T18:34:12 < gxti> Tekkkz: think about when the compiler decides to cast to float
2014-12-01T18:34:13 < karlp> .0 all the things!
2014-12-01T18:34:39 < karlp> or "* 1.0" all the things.
2014-12-01T18:35:09 < Tekkkz> karlp i dont know what you mean
2014-12-01T18:35:57 < karlp> try p = ( adc_wert * 1.0 / 4096.0) * 3.0 if you don't want to learn and understand promotion rules.
2014-12-01T18:36:05 < Tekkkz> ahh yes
2014-12-01T18:36:16 < Tekkkz> some times ago i had the same mistake with the same solution
2014-12-01T18:36:19 < Tekkkz> yes
2014-12-01T18:36:21 < Tekkkz> i remeber
2014-12-01T18:36:28 < Tekkkz> but can you explain why it is necessary?
2014-12-01T18:36:35 < karlp> " if you don't want to learn and understand promotion rules.
2014-12-01T18:36:44 < karlp> < gxti> Tekkkz: think about when the compiler decides to cast to float
2014-12-01T18:36:56 < Tekkkz> i dont understand this
2014-12-01T18:37:08 < gxti> Tekkkz: remember order of operations from math class?
2014-12-01T18:37:15 < gxti> it applies to data types too
2014-12-01T18:37:39 < Tekkkz> i dont understand, sorry
2014-12-01T18:37:42 < gxti> compiler looks at innermost stuff first, doesn't care what data type it eventually ends up in, only cares about what it is right now
2014-12-01T18:37:55 < gxti> so first it does 4092/4096, which is 0
2014-12-01T18:38:02 < gxti> then it multiplies by 3, which is still 0
2014-12-01T18:38:11 < gxti> then finally it says "oh i need to put this in a float" and you get 0.0
2014-12-01T18:38:16 < Tekkkz> ah ok
2014-12-01T18:38:19 < Tekkkz> thanks
2014-12-01T18:38:33 < Tekkkz> so with the .0 the compiler do the job right
2014-12-01T18:38:47 < gxti> so if you write adc_wert/4096.0f instead, it has to make it a float before it can divide and everything is ok.
2014-12-01T18:39:11 < Tekkkz> why?
2014-12-01T18:39:30 < gxti> there's no operation for "integer divided by float"
2014-12-01T18:39:45 < karlp> because 4096.0f is a float, 4096 is an int. and 4096.0 is a double :)
2014-12-01T18:39:46 < gxti> so if you divide an integer by a float then it has to make the integer a float first and you get a proper floating point divide
2014-12-01T18:39:47 < karlp> hooray!
2014-12-01T18:40:17 < gxti> floats really aren't needed here but i fear that explaining how to know which integer size to use would probably just make your head hurt more.
2014-12-01T18:40:18 < Tekkkz> so i must only change the 4096 to 4096.0f and the other values not?
2014-12-01T18:40:59 < gxti> technically not, but better to be consistent
2014-12-01T18:41:14 < karlp> or, if you're dumb like me, just put .0 on the end of all literals, and multiple all variables by 1.0 :)
2014-12-01T18:41:15 < Tekkkz> ok
2014-12-01T18:41:23  * gxti lunches
2014-12-01T18:41:31 < karlp> (and then you're not allowed to complain about it's performance)
2014-12-01T18:41:48 < karlp> alternatively: http://www.troll.me/images/angry-samuel-l-jackson/manuals-mother-fucker-do-you-read-them.jpg
2014-12-01T18:42:29 < decimad2_> gosh, I'm still parsing technical manuals, reading up linker script stuff, etc... and he's doing adc stuff already though with problems in c calculations...
2014-12-01T18:43:09 < Tekkkz> i just didnt remembered
2014-12-01T18:43:14 < karlp> decimad2_: there's some arm faqs on interrupt latency, chaing, preemption if this sorts of things are really critical for you.
2014-12-01T18:44:53 < decimad2_> karlp: I found some more roundups from arm about the topic. They all apply to 0 wait state only though for obvious reasons. So unless there is some clarification by STM, I would just copy stuff to sram and be done with it ;)

2014-12-02T00:00:53 < decimad2_> but there are images of the objects they found with it on a linked page!
2014-12-02T00:01:33 < decimad2_> zyp: I feared it :( Was in no position to test it quickly back then, sorry
2014-12-02T00:03:07 < zyp> why would you want to keep them in a separate section anyway?
2014-12-02T00:06:26 < zyp> I guess you could in theory separate them in the linker script
2014-12-02T00:06:46 < decimad2_> well to have isrs in ram but latency unrelevant stuff in flash or some combination and all
2014-12-02T00:07:20 < zyp> when you compile with -ffunction-sections, all functions will be kept in separate sections with the name containing the mangled function name
2014-12-02T00:07:32 < zyp> so you could probably filter the inputs in the linker script on that
2014-12-02T00:07:44 < decimad2_> text.*interrupt* > RAM
2014-12-02T00:07:48 < decimad2_> or something
2014-12-02T00:08:42 < decimad2_> will have a look at this tomorrow
2014-12-02T00:11:52 < zyp> .text._Z9interruptILN9Interrupt9ExceptionE*EEvv and .text._Z9interruptILN9Interrupt3IRQE*EEvv if you're using the same names as me
2014-12-02T00:14:11 < zyp> oh, and I still doubt the practical benefit of that
2014-12-02T00:14:52 < zyp> my guess is that flash latency is irrelevant, because half the working registers have to be stacked on interrupt entry, and that's plenty of time to fetch the ISR from flash
2014-12-02T00:15:28 < zyp> I'd even guess that running from ram would be slower if you need to fetch the ISR from the same memory block that you're stacking to
2014-12-02T00:17:51 < KreAture_Zzz> zyp unless you can fit your app in ram ?
2014-12-02T00:18:25 < zyp> the location of the rest of your application doesn't matter

2014-12-02T00:18:38 < KreAture_Zzz> zyp and load the relevant "mode" whenever you mode-switch
2014-12-02T00:19:00 < zyp> what mode?
2014-12-02T00:19:57 < zyp> the memory space is flat, so there's no «running from flash» and «running from ram» modes
2014-12-02T00:22:57 -!- Hydra_ [~Hydra@5751c98f.skybroadband.com] has joined ##stm32
2014-12-02T00:24:53 < decimad2_> there's still the mode that would map ram or flash at the beginning of the memory map
2014-12-02T00:26:03 < decimad2_> obviously stack could be parked on ccm :D
2014-12-02T00:26:43 < zyp> you still have to cope with bus contention/arbitration
2014-12-02T00:27:31 < decimad2_> Same situation as with flash/ram?
2014-12-02T00:27:46 < zyp> there is a benchmark of stm32f4 that documents that the fastest combination of memory use is to have code in flash and data in plain sram
2014-12-02T00:28:12 < zyp> and that makes sense, for that's how it is designed to be used
2014-12-02T00:28:29 < decimad2_> So what's ccm good for, if not for a second data source?
2014-12-02T00:29:59 < zyp> https://my.st.com/public/STe2ecommunities/mcu/Lists/cortex_mx_stm32/Attachments/22412/2012_STM32%20Technical%20Updates%20-%20Issue%201.pdf <- you'll want to read pages 42-45 in this
2014-12-02T00:31:20 < zyp> CCM is good when you have high speed dma masters active that's competing with the cpu for access to the normal sram
2014-12-02T00:37:26 < decimad2_> they are not comparing vs. flash + sram + ccm... I mean, if you have no other use for ccm, why not use it for stack and stuff? Doesn't seem to hurt at least...
2014-12-02T00:38:10 < decimad2_> that is, if the debugger has means to access ccm through the core...
2014-12-02T00:38:36 < decimad2_> I didn't even check this once -.- *taking notes*
2014-12-02T00:38:46 < zyp> stack in ccm would be similar to config 2
2014-12-02T00:39:00 < zyp> and yes, debugger can access anything the cpu can

2014-12-02T00:40:10 < zyp> the caveat of putting stack in ccm is that you can't allocate DMA buffers from stack, so you'd have to be careful about that

2014-12-02T00:42:37 < zyp> either way, all this is rather application specific optimizations
2014-12-02T00:43:06 < zyp> and therefore best left until you have an actual application to benchmark/profile before optimizing
2014-12-02T00:49:28 < decimad2_> Well, good to have the means around to quickly iterate then... To the topic: I incorrectly remembered that ccm had a dedicated bus... the design now seems overly strict to me coming back to it.

2014-12-02T01:03:09 < zyp> I prefer treating SRAM2 as part of SRAM1, which means stack happens to be in SRAM2 when I place it at the end
2014-12-02T01:04:14 < decimad2_> That's what I meant: The usual stack handling ends up putting stack, or at least the beginning of it, in dedicated memory
2014-12-02T01:04:33 < KreAture_Zzz> zyp I am sure I could do the same as I did on msp430 where I loaded a small section of code into ram and executed, then loaded another section later
2014-12-02T01:04:41 < KreAture_Zzz> zyp the loading is manual
2014-12-02T01:05:11 < zyp> KreAture_Zzz, sort of like banked memory?
2014-12-02T01:05:24 < zyp> that sounds like you insist on making it horrible :p
2014-12-02T01:06:26 < KreAture_Zzz> zyp when you are reprogramming flash you have no other choice in the msp430
2014-12-02T01:06:35 < KreAture_Zzz> it cannot run from flash while programming flash
2014-12-02T01:07:18 < KreAture_Zzz> I was using the flash as storage for data as well as executing code so I pulled "states" off the flash and put into memory and jumped to em
2014-12-02T01:07:26 < decimad2_> Was it your update firmware routine where the customer asked when the reboot happened? :P
2014-12-02T01:07:35 < KreAture_Zzz> yes decimad2_
2014-12-02T01:07:36 < KreAture_Zzz> lol
2014-12-02T01:07:49 < zyp> good thing stm32 can
2014-12-02T01:07:56 < KreAture_Zzz> the routines would then execute and handle the storage of long sequences of data into flash
2014-12-02T01:08:01 < decimad2_> I believe I will hear that story countless times to come ;)
2014-12-02T01:08:05 < KreAture_Zzz> lol
2014-12-02T01:08:17 < KreAture_Zzz> that is one of the strengths of a mcu though
2014-12-02T01:08:22 < KreAture_Zzz> the init can be incredibly fast
2014-12-02T01:08:35 < KreAture_Zzz> I had to help a buddy fix his model plane as it was doing odd jittery flights
2014-12-02T01:08:59 < KreAture_Zzz> turned out the rx was rebooting due to noise and re-acquiring the tx signal
2014-12-02T01:09:05 < KreAture_Zzz> all the time
2014-12-02T01:11:03 < kakeman> how long bypass cap loop length you concider failed?
2014-12-02T01:11:18 < kakeman> I have an inch long loop here
2014-12-02T01:14:14 < qyx_> an inch?
2014-12-02T01:14:16 < decimad2_> that definetely depends on dI/dt
2014-12-02T01:14:41 < kakeman> some high performance chip would go with it
2014-12-02T01:14:46 < decimad2_> and your track inductance!
2014-12-02T01:15:06 < kakeman> do you always do the math?
2014-12-02T01:15:56 < decimad2_> No, maybe I would, but they don't specify the values needed to calculate it anyways... it always looks like black magic to me
2014-12-02T01:16:00 < qyx_> why do you want to have your cap that long?
2014-12-02T01:16:08 < qyx_> place is near the pad and directly to groundplane
2014-12-02T01:16:22 < qyx_> *that far
2014-12-02T01:16:31 < qyx_> *place it
2014-12-02T01:16:33 < zyp> an inch kinda sounds too far to matter
2014-12-02T01:16:57 < kakeman> `loop length not distance
2014-12-02T01:17:47 < zyp> the rule of thumb is one for each supply pin, as close as possible
2014-12-02T01:17:56 < kakeman> tight design
2014-12-02T01:18:07 < zyp> I tend to have multiple bypass caps within an inch of any supply pin
2014-12-02T01:18:25 < zyp> eh, can't be that tight if you don't have any other caps closer
2014-12-02T01:21:24 < decimad2_> my spartan6 ev board has some of them easily as far away...
2014-12-02T01:24:13 < kakeman> I sacrafice some ground plane integry and via placing to get cap directly to supply
2014-12-02T01:26:16 < zyp> eh, do a four layer board if that matters
2014-12-02T01:27:29 < kakeman> those are nice
2014-12-02T01:27:56 < kakeman> wish I had reason use 4layers more often
2014-12-02T01:28:09 < zyp> it gets kinda addictive
2014-12-02T01:28:15 < qyx_> hm, F4 dfu needs just d+/d--, doesn't it?
2014-12-02T01:28:33 < zyp> unsure, it might want vbus too
2014-12-02T01:28:41 < zyp> since the peripheral actually monitors vbus
2014-12-02T01:28:45 < zyp> check AN2606
2014-12-02T01:28:57 < qyx_> they don't list it in the an2606 :S

2014-12-02T01:29:33 < decimad2_> I had three runs already trying to route a 3 phase rectifier with a 2 layer board cleanly and without vias on quick signals... I failed each time. Somewhen next week is the next time...
2014-12-02T01:30:30 < zyp> hmm
2014-12-02T01:30:47 < zyp> true, they don't say how they detect a usb cable
2014-12-02T01:31:41 < kakeman> how important groundplane is under oscillator?
2014-12-02T01:31:51 < zyp> ah
2014-12-02T01:31:53 < zyp> « This internal clock is also used for CAN and DFU (USB FS Device)
2014-12-02T01:31:54 < zyp> but only for the selection phase.»
2014-12-02T01:32:06 < zyp> so they can actually simply look for bus activity
2014-12-02T01:32:20 < zyp> so AN2606 suggests they only need DP/DM
2014-12-02T01:33:16 < qyx_> also i assume that any 1MHz-dividable xtal would work
2014-12-02T01:33:20 < qyx_> at least they say that
2014-12-02T01:34:09 < qyx_> but last time i checked on F407, it didn't work with 16MHz xtal and just d+/d- connected
2014-12-02T01:34:12 < qyx_> or i did something wrong
2014-12-02T01:34:26 < qyx_> and i would like to be sure this time :S
2014-12-02T01:34:29 < zyp> I haven't tested myself, so I can't tell
2014-12-02T01:34:52 < zyp> is there a reason besides lazyness that you're not just rolling your own bootloader?
2014-12-02T01:35:23 < qyx_> you said that
2014-12-02T01:35:41 < qyx_> actually i will have one
2014-12-02T01:36:08 < qyx_> but it will flash images from external spi flash
2014-12-02T01:36:32 < qyx_> i would like to keep the possibility to do differential ota updates (radio)
2014-12-02T01:37:00 < zyp> but that doesn't explain why you'd like to keep the built in bootloader ;)
2014-12-02T01:37:08 < qyx_> i wanted to have something for initial flashing and usb connector is available
2014-12-02T01:37:08 < zyp> s/keep/use/
2014-12-02T01:37:23 < qyx_> so no additional work => i am happy

2014-12-02T05:21:23 < jadew> I just opened the battery compartment on my SA to see what kind of battery it has (it was showing a battery error on boot up)
2014-12-02T05:21:42 < jadew> turns out the previous owner doesn't know that + goes to red and - to black :/
2014-12-02T05:21:49 < jadew> the battery inside was brand new
2014-12-02T05:23:31 < madist> you're saying you got a commercial device with a non-polarised battery connector ?
2014-12-02T05:23:41 < jadew> yes
2014-12-02T05:24:30 < jadew> but the wires are colored
2014-12-02T05:25:17 < jadew> anyway, I'm glad I don't have to buy a new battery hehe
2014-12-02T05:25:39 < jadew> ah and I also saw a really nice trick - should have made a photo
2014-12-02T05:26:08 < jadew> someone smarter than the guy who didn't know how to fit the battery made a battery adapter to fit newer models of batteries in there
2014-12-02T05:26:54 < jadew> the newer batteries are much shorter so he used a screw, two nuts and heat shrink to make something that fits over newer batteries but extends them to the full length the old ones had

2014-12-02T13:08:57 < Fleck> anyone used MAX7219? I don't get it, Iset from datasheet says segment current limit, means what? Individual led? Individual digit or for all leds?
2014-12-02T13:09:21 < dongs> all leds.
2014-12-02T13:09:30 < dongs> so youcant use it to drive ones that are several leds for some segmetns
2014-12-02T13:09:49 < Fleck> yeah and I can't drive 20mA leds :D
2014-12-02T13:10:05 < Fleck> well, I can but, they will be dull
2014-12-02T13:10:07 < dongs> what i mean is its same current limit for all sinks
2014-12-02T13:10:20 < dongs> 20mA or wahtever it is
2014-12-02T13:11:39 < dongs> 320mA minimum sink current for all segments
2014-12-02T13:11:51 < dongs> that surely sounds like you cna drive 40mA leds?
2014-12-02T13:12:29 < dongs> only one digit is on , its 1/8 scan or whatever.
2014-12-02T13:12:35 < Fleck> dunno, I have 8x 20mA leds and can't make them bright no matter what
2014-12-02T13:12:47 < dongs> 'leds' or 7seG?
2014-12-02T13:12:51 < Fleck> leds
2014-12-02T13:13:09 < dongs> and duty cycle is set to max?
2014-12-02T13:13:20 < Fleck> yep
2014-12-02T13:13:34 < jpa-> did you measure the actual current?
2014-12-02T13:13:55 < dongs> table 11 shows what you neend for RSET
2014-12-02T13:14:06 < Fleck> yep, and I did that! :)
2014-12-02T13:14:27 < dongs> its kOhm btw.
2014-12-02T13:14:35 < Fleck> yes, I know! :)
2014-12-02T13:14:48 < Fleck> jpa-: when I connect A metter, leds get even less bright :D
2014-12-02T13:14:48 < dongs> you suck at something then
2014-12-02T13:16:07 < Fleck> right! :D
2014-12-02T13:19:47 < jpa-> Fleck: then switch to a larger current area on your meter
2014-12-02T13:20:25 < Fleck> I did that also, current gets up a bit, but for all 8x LEDs I got ~10mA

2014-12-02T13:37:47 < decimad> Okay guys, scons or not scons? Bad thing is, you need to install python... had they used C/C++, the normal toolchain could have taken care of it... hrmmm
2014-12-02T13:38:47 < zyp> what normal toolchain? which platform are you on that ships with a compiler by default but not python? :p
2014-12-02T13:39:57 < akaWolf> decimad: you can find interesting qmake then
2014-12-02T13:40:19 < akaWolf> qmake & make

2014-12-02T13:52:03 < decimad> zyp: Consider plattform A, which comes with none. Without scons: Install compiler. With scons: Install compiler, install correct python version.
2014-12-02T13:52:45 < decimad> and install Scons, I forgot ;)
2014-12-02T13:52:50 < zyp> so what are you using to build in the first case?
2014-12-02T13:53:14 < decimad> make, which usually comes bundled with the toolchain and is non-intrusive so to speak
2014-12-02T13:53:31 < zyp> you said c/c++, not make
2014-12-02T13:53:53 < decimad> -.-
2014-12-02T13:54:02 < zyp> so I were thinking you were talking about building something scons-ish with gcc

2014-12-02T13:54:36 < zyp> and that argument wouldn't make sense, since the arm cross compiler wouldn't be able to build for the host platform
2014-12-02T13:54:53 < akaWolf> you need a python only on host machine
2014-12-02T13:54:57 < akaWolf> do you know?
2014-12-02T13:54:58 < zyp> so anyway, which platforms do you actually care about?
2014-12-02T13:55:22 < akaWolf> there is no need in python on target machine...
2014-12-02T13:55:49 < decimad> akaWolf: hehe, so much I know ;)
2014-12-02T13:55:51 < zyp> I think several if not most of the common linux distributions are already using python for included utility software
2014-12-02T13:55:58 < akaWolf> I think, overall hosts have properly python versions
2014-12-02T13:56:07 < decimad> Well, I'm caring for the windows platform!
2014-12-02T13:56:15 < Steffann> except when you're using windows akaWolf :P
2014-12-02T13:56:17 < zyp> and os x ships with python by default
2014-12-02T13:56:21 < Steffann> but how hard is it to install python?
2014-12-02T13:56:26 < akaWolf> there is exist all versions of Python for Win
2014-12-02T13:56:30 < zyp> and python is readily available for windows too
2014-12-02T13:56:37 < decimad> Of course it is.
2014-12-02T13:56:41 < zyp> I've used scons on windows, it's painless
2014-12-02T13:56:41 < Steffann> I bet the average developer has it already installed.
2014-12-02T13:56:45 < akaWolf> Steffann: I have latest Python for Windows too...
2014-12-02T13:56:56 < decimad> I'm not questioning the availability or doability ;)
2014-12-02T13:57:13 < decimad> I'm not questioning anything actually ;)
2014-12-02T13:57:19 < Steffann> even dongs has python installed and he hates python.
2014-12-02T13:57:25 < akaWolf> well ok
2014-12-02T13:57:37 < akaWolf> dongs hates almost all
2014-12-02T13:57:42 < zyp> I'm guessing «no, I fucking don't»
2014-12-02T13:58:00 < decimad> It's only that you need like x versions of python seemingly... for scons it must be < 3, is that a problem?
2014-12-02T13:58:08 < zyp> no
2014-12-02T13:58:08 < akaWolf> Python is nice enought for me :P
2014-12-02T13:58:30 < akaWolf> it's not a problem even for Win
2014-12-02T13:58:32 < zyp> python 2 and python 3 are maintained in parallel
2014-12-02T13:58:36 < akaWolf> yeah
2014-12-02T13:58:56 < akaWolf> I have installed both at my Win7 machine
2014-12-02T13:59:04 < zyp> so you'll continue to get maintained python 2 packages for the forseeable future
2014-12-02T14:00:05 < decimad> What about path lookup? Is the version encoded in the binary name?
2014-12-02T14:00:19 < akaWolf> hm
2014-12-02T14:00:21 < zyp> yes
2014-12-02T14:01:02 < akaWolf> I dont think so in Windows
2014-12-02T14:01:21 < akaWolf> python.exe for both: 2 and 3 versions
2014-12-02T14:01:31 < akaWolf> but you can rename/etc
2014-12-02T14:01:39 < akaWolf> change the PATH variable
2014-12-02T14:01:42 < zyp> either way, you'll install scons into the correct version, and when you run scons that version will be used implicitly
2014-12-02T14:02:20 < dongs> zyp, nrf51822 is eol?

2014-12-02T14:03:36 < dongs> NEW ENHANCEMENTS include variants with 32kB RAM for improved application performance, and 128kB flash wafer level chip scale package (WLCSP) options for smaller wearable designs.
2014-12-02T14:03:37 < zyp> nrf site says active for the chip itself
2014-12-02T14:03:40 < dongs> yeah
2014-12-02T14:03:52 < qyx_> pfff wearable designs
2014-12-02T14:03:56 < zyp> 32k ram is nice
2014-12-02T14:04:10 < zyp> 16k was horrible with the stack eating over half of it
2014-12-02T14:04:39 < akaWolf> qyx_: guys thinking, that you are smart enough for install a proper versions ;)
2014-12-02T14:06:45 < dongs> i wonder what happeend to evalboards
2014-12-02T14:09:55 < decimad> since 20 years now we have an environment path variable that encodes all the paths in a huge string and an edit box to change it... there must be a better way...
2014-12-02T14:11:25 < akaWolf> it's available for Win too :)

2014-12-02T14:54:29 < mitrax> what's the recommended way to perform non blocking receives on an UART when the length is not known in advance? (typically when the other side send stuff with a cr lf delimiter). stm32cube's HAL_UART_Receive_IT/DMA() won't complete unless the full length has been received and they don't accept a timeout, issuing a non blocking recv with a single byte at once doesn't sound like a good idea...

2014-12-02T18:26:01 < kakeman> and no need for isolation - common ground
2014-12-02T18:26:17 < decimad2> well, then here you basically need the sensor ic, 1-2 resistors, a capacitator and an ad converter

2014-12-02T18:27:10 < kakeman> opamp

2014-12-02T18:49:15 < qyx_> shunt + rail to rail opamp should be enough
2014-12-02T18:49:52 < dongs> ruby on rais opamp
2014-12-02T18:49:52 < qyx_> you have to choose the type that can go beyond its power supply rails
2014-12-02T18:50:26 < kakeman> I show my ltspice model later
2014-12-02T18:50:27 < qyx_> eg. with mcp6001/2/4 you should be able to do high side sensing, it allows vdd+0.3 common mode voltage
2014-12-02T18:50:41 < kakeman> it's still low side
2014-12-02T18:50:43 < qyx_> and it is like $0.15 or so
2014-12-02T18:50:53 < qyx_> low side is bad
2014-12-02T18:50:57 < qyx_> it shifts your grounds
2014-12-02T18:51:56 < qyx_> also there are current sense amplifiers which can have common mode voltage as high as 60V+
2014-12-02T18:54:50 < qyx_> i will let you know, i am going to try beaky-style solar charger

2014-12-03T13:23:20 < trepidaciousMBR> STM32 AES-GCM really doesn't seem to actually do GCM, it encrypts to the same ciphertext as AES-CTR, whereas other AES-GCM implementations produce different ciphertext. So that's annoying.
2014-12-03T13:25:01 < jpa-> or maybe your config is just wrong somehow?
2014-12-03T13:25:21 < jpa-> it would seem a bit much for even ST to advertise GCM if they don't actually support it at all
2014-12-03T13:27:54 < trepidaciousMBR> Yeah you would think... It may well be something I'm doing, but I'm pretty much exactly replicating the STM crypto library. Unfortunately I can't find any test code with known key/iv/plain/ciphertext
2014-12-03T13:28:17 < trepidaciousMBR> Also they are very specific about wanting a 16 bit IV, whereas everyone else in the world uses 12 bit
2014-12-03T13:28:51 < zyp> bit or byte?
2014-12-03T13:29:24 < trepidaciousMBR> Sorry byte
2014-12-03T13:31:55 < jpa-> STM32 world-class crypto: up to 16 bits security!
2014-12-03T13:32:04 < trepidaciousMBR> heh yeah ;)
2014-12-03T13:33:35 < trepidaciousMBR> I think the problem is probably the IV, because everything I've found online indicates that AES GCM definitely uses CTR for encryption, but uses 12 bytes. The STM32 output matches exactly what I get from a standard crypto library using AES CTR and the same IV
2014-12-03T13:33:43 < decimad2> is that full bit encryption?
2014-12-03T13:33:46 < trepidaciousMBR> so I guess AES GCM mangles the IV

2014-12-03T13:38:29 < trepidaciousMBR> I sometimes really think that cyptographers just deliberately make this stuff obscure, so they can point and laugh when it goes wrong

2014-12-03T16:21:28 < trepidaciousMBR> jpa-: I think it is the IV value, looks like GCM internally uses a counter that consists of 12 bytes of IV, and 4 bytes of counter. I'm really hoping that the "IV" used by STM32 is just the same thing, in which case I should just have to initialise it with the actual IV and the counter set to 1. That doesn't seem to work yet, but you never know ;)

2014-12-03T18:21:57 < brabo> i use rtc with libopencm3
2014-12-03T18:21:59 < brabo> not hard
2014-12-03T18:22:07 < dirty_d> with f3?
2014-12-03T18:22:13 < brabo> no, f1
2014-12-03T18:22:19 < brabo> so mileage may vary
2014-12-03T18:22:23 < dirty_d> right, it has an include for everything but f3
2014-12-03T18:22:37 < dirty_d> but in the documentation, it shows rtc as a module of the f3
2014-12-03T18:22:49 < brabo> f3/rtc.c no good?

2014-12-03T18:25:15 < brabo> f3 might be a subset
2014-12-03T18:26:00 < brabo> so try out the rtc_common_l1f024.h but expect some things not to work.. i think if you are lucky, you have what you need there

2014-12-04T01:35:07 < GargantuaSauce> cmsis only covers the cores' functionality
2014-12-04T01:37:03 < Isvara_> Hmm. I was previously using an NXP MPU, and I downloaded the CMSIS library from there. It had part-specific headers in there, like system_LPC17xx.h. Does ST not do something similar?
2014-12-04T01:37:24 < GargantuaSauce> it does, but that's not part of the cmsis library in any case
2014-12-04T01:37:45 < englishman> they call it the st standard peripheral library and it includes cmsis
2014-12-04T01:38:09 < GargantuaSauce> yeah stdperiphlib, or the newer stm32cube
2014-12-04T01:38:22 < englishman> which one is timecube only? L1?
2014-12-04T01:38:27 < GargantuaSauce> think so
2014-12-04T01:38:51 < GargantuaSauce> stdperiphlib is definitely the preferred one i think if you're using a mcu it supports

2014-12-04T02:15:51 < scummos_> to which banks should this assumption apply? all different banks?
2014-12-04T02:15:52 < dongs> how do you determine this
2014-12-04T02:16:13 < scummos_> I have a pin which is toggled with a certain frequency (10 MHz-ish)

2014-12-04T02:16:32 < scummos_> I sample it like while ( high ) { } and then I write the value to a buffer

2014-12-04T02:16:47 < scummos_> this works when I run just that

2014-12-04T02:18:25 < scummos_> it works
2014-12-04T02:18:27 < scummos_> but it's not very fast

2014-12-04T02:18:46 < scummos_> yes
2014-12-04T02:18:56 < scummos_> I did that, a timer which triggers the DMA single transfer
2014-12-04T02:19:02 < dongs> .. single?
2014-12-04T02:19:02 < dongs> no
2014-12-04T02:19:06 < dongs> of course that wouldnt work
2014-12-04T02:19:14 < dongs> (or be slow)
2014-12-04T02:19:17 < scummos_> ok, what should I do instead?
2014-12-04T02:19:34 < dongs> timer used as a trigger for each transfer for a DMA buffer of XXX bytes that you need to fill
2014-12-04T02:20:24 < scummos_> yeah, but I only need to transfer a single byte each time
2014-12-04T02:20:45 < scummos_> then wait
2014-12-04T02:20:47 < dongs> you want this to be periodic capture right?
2014-12-04T02:20:49 < scummos_> yes
2014-12-04T02:21:00 < dongs> what is the wait condition? period is samea?
2014-12-04T02:21:08 < scummos_> 8 parallel inputs on the GPIO, should be sampled each 0.1us

2014-12-04T02:21:38 < dongs> right, so, timer + DMA from gpio port, on each timer tick (or overflow, whiechever way you can setr it up), it will DMA 8 bits into a buffer and increment.
2014-12-04T02:21:46 < scummos_> tried that
2014-12-04T02:21:48 < scummos_> it's too slow
2014-12-04T02:22:02 < dongs> how can it be slow, onl hardware is involved
2014-12-04T02:22:13 < scummos_> it can do a few MHz, like 7 or so, but not 15
2014-12-04T02:22:23 < dongs> > how can it be slow, only hardware is involved
2014-12-04T02:22:47 < scummos_> I don't know, if I set the timer to overflow after fewer circles from some point it just doesn't get faster any more
2014-12-04T02:22:52 < scummos_> *fewer counts
2014-12-04T02:24:17 < scummos_> oh, additionally, when using linked list DMA, it apperently takes a moment to load the next LLI item after it finished processing the current block
2014-12-04T02:24:32 < scummos_> which is not good, because I want this to run continuously
2014-12-04T02:25:39 < Laurenceb> that was dongs right?
2014-12-04T02:26:02 < scummos_> hm?
2014-12-04T02:28:06 < scummos_> I could eventually live with it not running continuously, but I need at least 4000 values, the 1024 which LLI DMA can do are not enough
2014-12-04T02:28:23 < Laurenceb> dongs:  http://techsmartly.net/freePS3.php
2014-12-04T02:28:27 < scummos_> (after the 1024, it loads the next config item, which introudces a delay)
2014-12-04T02:29:23 < englishman> is your gpio fast enough
2014-12-04T02:29:28 < scummos_> well hopefully
2014-12-04T02:29:34 < scummos_> it runs with the 204 MHz clock
2014-12-04T02:29:41 < scummos_> and I need to sample it at like 12 MHz
2014-12-04T02:29:58 < scummos_> the bottleneck must be either the bus, or the SRAM
2014-12-04T02:32:28 < scummos_> is it possible that e.g. USB and GPIO use a common bus?
2014-12-04T02:33:17 < scummos_> or, more generally asking: where can I find information about this kind of stuff? the user manual doesn't really seem to contain any information about the bus matrix (or I'm looking in the wrong place)
2014-12-04T02:33:25 < dongs> scummos_: no double buffer cpability in DMA controller?
2014-12-04T02:34:13 < dongs> sounds like LPC is just shit all around
2014-12-04T02:34:38 < dongs> better upgrade to Renesas RZ/A1H
2014-12-04T02:35:41 < scummos_> well, unless it's pin-compatible, which it will not be, that'll be an effort ;P
2014-12-04T02:36:08 < scummos_> I wouldn't know it has double buffering
2014-12-04T02:36:13 < scummos_> maybe I could use the SGPIOs?
2014-12-04T02:39:27 < scummos_> yeah, I should try using the SGPIO

2014-12-04T14:38:18 < karlp> heh, I bet it falls over all the time though
2014-12-04T14:38:23 < decimad> So there are various SMD packages for power mosfets and the almighty to-220. I need to place 3 half bridges. TO-220 allows for cooling at the sides of the board, whereas for smd parts cooling from top seems suboptimal. Otoh I can place thermal vias and cool from below the board. But what would I need to isolate and attach the  heatsink?

2014-12-04T16:17:12 < kakeman> they seem to have ton of shiet
2014-12-04T16:17:30 < karlp> qyx_: 8031 is EOL apparently, (was just tyring to find what made it special vs the other micrel ones)
2014-12-04T16:17:56 < qyx_> karlp: yep, they have 8081 or something like that
2014-12-04T16:18:03 < qyx_> pin compatible
2014-12-04T16:18:30 < qyx_> and it is small and cheap and nice

2014-12-04T16:23:02 < decimad> karlp: thanks for notification... I'm waiting eagerly for 4.9 to show up already because they mentioned they'd fix on lto and link order dependency
2014-12-04T16:23:26 < karlp> it seems to be _marginally_ cheaper than the micrel part for small orders on digikey

2014-12-04T20:16:13 < decimad> Hrmm, so I spent some time to calculate switching times... anybody knows about rectifiers? My result is, each mosfet switching cycle spends ~120ns in the power dissipation zone... does this sound bad?
2014-12-04T20:17:05 < decimad> I acknowledge that this is really totally offtopic :(
2014-12-04T20:18:58 < BrainDamage> 120ns per se means nothing
2014-12-04T20:19:10 < BrainDamage> what matters is how much is that relative to the overall period
2014-12-04T20:19:58 < BrainDamage> your mosfets are dissipating Vcc*Iload ( provided the load is largely inductive ) during the quadratic region, and (Iload)^2Rdson in ohmic
2014-12-04T20:20:20 < decimad> BrainDamage: granted, I was just curious if that sounds like reasonable switching times, since my calculations might be totally off
2014-12-04T20:20:32 < BrainDamage> do a weighted average of the dissipation in either area and you'll have the overall power
2014-12-04T20:20:39 < decimad> yes, of course
2014-12-04T20:21:22 < BrainDamage> it's not an absurd number
2014-12-04T20:21:27 < BrainDamage> if that's what you're asking
2014-12-04T20:23:09 < decimad> Yes, that's what I was asking
2014-12-04T20:23:55 < BrainDamage> but according to the switching speed and power dissipation your mos still may or may not blow up anyway
2014-12-04T20:25:07 < decimad> In my modelling it's totally limited by the ~500 mA maximum driver current... for my model I had to model that into an internal driver voltage source resistance, because they're only stating 500 mA @ some gate capacity... I can't to something with that...

2014-12-04T20:58:49 < BrainDamage> 40kHz is 25us period, during which you'll have 2 transitions, worst case is: 30V*10A*2*125ns/25us+RDSon*(10A)^2*(1-(125ns/25us))

2014-12-04T21:30:52 < decimad2_> BrainDamage: I calculated 100% modulation with switches nonetheless... I don't use the rectangular approximation though, but triangular shapes of rising current and falling drain source voltage in their respective phases. Rdson was taken as 1.5mOhm... but it doesn't contribute the large part. I could look out for a smaller fet (way more rdson, less gate charges)
2014-12-04T21:32:53 < englishman> Dirty_d choose connect under reset in your flashing program
2014-12-04T21:32:59 < BrainDamage> during switching time, taking a triangular approximations is wrong if your load is inductive
2014-12-04T21:33:16 < BrainDamage> because it'll conduct the average value
2014-12-04T21:33:25 < BrainDamage> unless it's a dcm system

2014-12-04T21:40:03 < decimad2_> Yes... but which one is correct? :D Obviously this can't be correct either, because you can drop Vdd at the Fet and still drive a current through the load...
2014-12-04T21:40:49 < BrainDamage> what do you mean "which one is correct" ?
2014-12-04T21:41:14 < decimad2_> Well, should I take rectangles where they indicate ramps?
2014-12-04T21:41:34 < BrainDamage> you can take the triangle or the rectangle with half height
2014-12-04T21:41:41 < BrainDamage> both lead to the same result :p
2014-12-04T21:41:53 < decimad2_> Oh, you took half the height?
2014-12-04T21:42:17 < decimad2_> Well either way... the hard part are the times... this can be quickly adjusted
2014-12-04T21:42:47 < decimad2_> I can't understand why I couldn't find an app to calculate the times based on the charges...

2014-12-04T23:20:47 < scummos_> and you need to tell the linker where it can find it

2014-12-05T02:21:07 < upgrdman> tempted to get some fet drivers. will need some way to convert 3.3v to 10-20V for the driver. what boost converters do you guys like?
2014-12-05T02:22:23 < upgrdman> or even better, a gate driver with built in boost
2014-12-05T02:23:00 < dongs> sup pross
2014-12-05T02:23:18 < dongs> upgrdman: there's some t hat can run off external voltage
2014-12-05T02:23:23 < dongs> but limited to around 20V or so
2014-12-05T02:23:26 < upgrdman> ya
2014-12-05T02:23:36 < upgrdman> but i have no external voltage >10V
2014-12-05T02:23:38 < dongs> whats hte voltage youre switching?
2014-12-05T02:23:41 < upgrdman> irs2103 is what im looking at atm
2014-12-05T02:24:10 < dongs> irs2301 is whaT I used i think
2014-12-05T02:24:10 < upgrdman> dongs: maybe 5-9v supply for the load
2014-12-05T02:24:13 < dongs> oh
2014-12-05T02:24:20 < upgrdman> but irs2103 seems to have 10v min lockout
2014-12-05T02:24:23 < dongs> thats a bit low I guess.
2014-12-05T02:24:24 < dongs> right
2014-12-05T02:25:00 < dongs> why dont you run your load off 12V
2014-12-05T02:25:19 < upgrdman> i plan to use a 2S LiPo
2014-12-05T02:25:32 < upgrdman> so 8.4v peak, 7.4v nom 6v min
2014-12-05T02:25:49 < dongs> anywho, since gate drive stuff doesnt need a lot of current for boot voltage you can use a cheap voltage doubler/booster with switched capacitors

2014-12-05T02:26:41 < dongs> just google switched capacitor boost, ti/max/etc make a whoel shitload of them
2014-12-05T02:26:54 < upgrdman> k
2014-12-05T02:27:26 < dongs> i only did this stuff at 3S and above lipo, i dont know what happens at 2S
2014-12-05T02:27:48 < dongs> you can double your lipo voltage but then it'll be even higher than the load voltage, i dunno if that workrs or what
2014-12-05T02:28:14 < dongs> (for gate driver boot vcc)
2014-12-05T02:28:38 < upgrdman> im also have a do-it-all smps converter. seems like i want something that isn't made :( like 1-15V in, 2-20v out ... a sort of "fuck it, one chip for all my psu needs"
2014-12-05T02:28:52 < upgrdman> s/have/after

2014-12-05T02:29:21 < dongs> Simon--: hes on 2S, he can just do it directly from battery voltage
2014-12-05T02:29:33 < dongs> but then the 'boost' will be above main voltage.

2014-12-05T02:30:55 < dongs> or 2101s or something similar
2014-12-05T02:31:07 < upgrdman> oh fuck yes.
2014-12-05T02:31:11 < upgrdman> 2301 will work
2014-12-05T02:31:30 < Simon--> upgrdman: ir2103 is actually max postive going threshold 9.8V, typ 8.9V, min 8V and cut-off is min 7.4V, typ 8.2V, max 9V, .. so lots of cheapo escs just do 7805->doubler->ir2101
2014-12-05T02:31:40 < upgrdman> i wonder why this esc uses 2103 and two smps chips...
2014-12-05T02:32:51 < Simon--> yeah. with 2S, may as well just ir2301, I guess
2014-12-05T02:33:41 < Simon--> just check that your fets won't blow up due to Rds.on at the min cut-off of 3V Vgs

2014-12-05T07:52:03 < dongs> that one even has low battery output
2014-12-05T07:52:12 < dongs> why need a gauge if you can jus turn on led hwen battery is getting low
2014-12-05T07:52:21 < dongs> (and make it evne lower)
2014-12-05T07:57:57 < upgrdman> nice

2014-12-05T10:31:19 < zyp> dongs, so, about the wires
2014-12-05T10:32:35 < dongs> zyp, yeah
2014-12-05T10:33:24 < zyp> I need a male-female extension for XH, 30cm, wires on the plug should be in the order yellow, white, red, black, and reversed on the socket
2014-12-05T10:33:55 < dongs> drawe all that shit in mspain and email it
2014-12-05T10:34:02 < dongs> i got a new place that should be cheaper than my old scamplace
2014-12-05T10:34:22 < dongs> is that all? you dont need the spade plug shits again?
2014-12-05T10:34:26 < zyp> and then I need male-male XH-ZH cables, also 30cm, wires on XH should be yellow, none, red, black, wires on ZH should be black, yellow, red
2014-12-05T10:35:13 < zyp> i.e. pin 1 on XH plug should in both cases be yellow, and pin 1 on ZH should be black
2014-12-05T10:35:23 < dongs> could you mspaint that real quick with pics of connector ends and shit?
2014-12-05T10:35:36 < dongs> these guys arent gonna understand unless its on the level of simple english wikipedia
2014-12-05T10:37:23 < zyp> ok, I'll try drawing some shit
2014-12-05T10:39:41 < dongs> but should be doable.
2014-12-05T10:39:46 < dongs> any specific request for wire gauge?
2014-12-05T10:39:51 < dongs> this stuff sounds very thin, no?
2014-12-05T10:40:00 < dongs> ZH is like 1.25mm pitch connector?
2014-12-05T10:40:03 < dongs> or even less
2014-12-05T10:40:39 < dongs> 1.5mm
2014-12-05T10:40:44 < dongs> more than i thought
2014-12-05T10:40:50 < dongs> seems AWG26 is recommended for it
2014-12-05T10:46:38 < akaWolf> ohoho
2014-12-05T10:54:56 < zyp> http://bin.jvnv.net/f/ypwsn.png
2014-12-05T10:55:30 < zyp> wire gauge for the XH-XH can probably be same as the blade ones, whatever that was
2014-12-05T10:55:39 < zyp> wire gauge for XH-ZH can probably be thinner
2014-12-05T10:58:32 < zyp> I guess 100 of each is good for now
2014-12-05T10:58:49 < dongs> ok so youre gonna make me copy all this chat log and email, instead of mailing me all teh instrucitons? k

2014-12-05T13:21:06 < trepidaciousMBR> There's no problem padding out a valid binary image for MCU flash is there?

2014-12-05T14:24:58 < zyp> dongs, and if you don't mind, some vreg fitting the footprint and a rs485 transceiver too
2014-12-05T14:25:36 < zyp> hmm, I think I still have usb connectors left
2014-12-05T14:28:28 < dongs> find the parts and email

2014-12-05T14:32:14 < jpa-> MAX485? DS751?  both are quite power-hungry, though
2014-12-05T14:33:07 < dongs> is that the sot23 thing with standard pinout?

2014-12-05T14:35:11 < akaWolf> a white list*
2014-12-05T14:35:29 < zyp> jpa-, quite power hungry being 500µA?

2014-12-05T14:37:03 < jpa-> zyp: ah, remembered wrong, only DS751 is power hungry

2014-12-05T14:39:03 < dongs> Yep
2014-12-05T14:39:50 < zyp> ordering that few parts from digikey or mouser would be kinda silly, shipping would cost more than the parts

2014-12-05T15:00:35 < Claude> -20dBm ?
2014-12-05T15:00:43 < Laurenceb_> what frequency?
2014-12-05T15:00:55 < Claude> 2.4ghz i guess
2014-12-05T15:01:00 < Laurenceb_> boring
2014-12-05T15:01:12 < Claude> yeah :)
2014-12-05T15:03:03 < Claude> yeah because they have a DC/DC build in , btw the 3.7mA figure is with "an ideal DC/DC converter" according to their datasheet
2014-12-05T15:03:39 < Claude> still quite nice for the RX

2014-12-05T15:12:34 < karlp> that's a full single unit load though, if it matters for your application, but it's the cheapest we found,
2014-12-05T15:12:40 < karlp> I think dongs ended up using it too
2014-12-05T15:13:35 < karlp> that's the slew rate limited version, aka "easy mode"
2014-12-05T15:16:02 < karlp> anyone know how to get this to work? http://stackoverflow.com/questions/19403233/compile-time-struct-size-check-error-out-if-odd
2014-12-05T15:16:23 < karlp> I can declar an array of size 0 and g-a-e just warns me about the unused variable, not a compile time error
2014-12-05T15:16:42 < dongs> heh
2014-12-05T15:17:12 < dongs> karlp: i did this for sizeof(struct>2048)
2014-12-05T15:17:34 < zyp> karlp, that's 3.3V though
2014-12-05T15:17:50 < dongs> karlp: https://github.com/multiwii/baseflight/blob/master/src/config.c#L35
2014-12-05T15:17:53 < zyp> I've got the board wired for a 5V supply
2014-12-05T15:18:07 < karlp> zyp: oh, missed that, intersil has others, I'm sure.
2014-12-05T15:18:23 < karlp> the pinouts are all the same for all the so8 transceivers we tried anyway
2014-12-05T15:18:25 < dongs> and ct_assert is https://github.com/multiwii/baseflight/blob/master/src/config.c#L12
2014-12-05T15:18:38 < dongs> so i think you can do sizeof(foo) % 2 or somesthig? as assert

2014-12-05T15:20:11 < karlp> but those are _gross_ error messages :)
2014-12-05T15:20:19 < karlp> at least it stops the compile with that one.
2014-12-05T15:20:29 < dongs> hm
2014-12-05T15:20:41 < dongs> well, blame gcc.
2014-12-05T15:20:51 < dongs> it works flawlessly here with keilPRO
2014-12-05T15:20:51 < karlp> yeah, it works at least :)
2014-12-05T15:20:58 < karlp> what message do you get when it's wrong?

2014-12-05T15:34:53 < karlp> stupid c11 using _ for all the shit
2014-12-05T15:35:14 < zyp> it's supposed to be wrapped by a macro in assert.h

2014-12-05T15:36:30 < karlp> well, now it's working with c11, so that's actually much sexier, except netbeans doesn't understand the _Static_assert and underlines it in red.
2014-12-05T15:36:33 < karlp> minor price
2014-12-05T15:36:44 < zyp> so wrap it with a macro?

2014-12-05T16:27:05 < GargantuaSauce> so i can happily procrastinate on one by working on another

2014-12-05T16:38:58 < dongs> no
2014-12-05T16:39:08 < dongs> if it is, probably slow as shit
2014-12-05T16:40:52 < Steffanx> Yes Taxman. I think openocd supports it
2014-12-05T16:41:11 < dongs> but only if you build it from sores using FTDI lib
2014-12-05T16:41:19 < dongs> cuz opensores one is too slow lolololol and they cant prebuild for closed-sores one
2014-12-05T16:41:50 < Taxman> well...
2014-12-05T16:41:58 < dongs> did you know? There's dual-link HDMI
2014-12-05T16:42:10 < Taxman> you mean build it from source?
2014-12-05T16:42:23 < zyp> dongs, what?
2014-12-05T16:42:30 < dongs> yep
2014-12-05T16:42:32 < dongs> 28pin connector
2014-12-05T16:42:34 < dongs> defined in 1.4 spec
2014-12-05T16:42:35 < dongs> heh
2014-12-05T16:42:41 < zyp> wtf
2014-12-05T16:42:41 < Steffanx> Taxman they probably know more about it in #openocd or otherwise just try some recent version of openocd :)
2014-12-05T16:42:44 < dongs> its like dua-link dvi, has 5 tdms pairs
2014-12-05T16:42:50 < zyp> 6 you mean?
2014-12-05T16:42:52 < dongs> im sure: nobody uses it
2014-12-05T16:42:55 < dongs> 6 with clock yeah
2014-12-05T16:43:02 < dongs> err, 0..5
2014-12-05T16:43:04 < dongs> + clcok
2014-12-05T16:43:06 < zyp> no, dvi is 6+clock
2014-12-05T16:43:13 < dongs> rite
2014-12-05T16:43:27 < zyp> obviously, since normal is 3+clock
2014-12-05T16:44:09 < dongs> http://www.elitelex.com/HDMI-BIF.jpg
2014-12-05T16:44:15 < dongs> it is type B connector
2014-12-05T16:44:27 < dongs> (type A is normal, C is mini D is micro)
2014-12-05T16:44:39 < dongs> i wonder if there's a single hardware device with such shit on it
2014-12-05T16:44:45 < dongs> or it just lives in the spec
2014-12-05T16:47:01 < trepidaciousMBR> The important thing is to start ever single connector with a really big design, then suddenly realise that people like small connectors, and make it smaller by increments to make sure nothing is compatible
2014-12-05T16:47:09 < dongs> yep
2014-12-05T16:47:30 < dongs> this type-b hdmi might be about as useful as mini-dvi that apple used for like a year
2014-12-05T16:48:19 < trepidaciousMBR> I think I remember that. I'm still just really glad my macbook has an actual HDMI connector on it.
2014-12-05T16:48:34 < trepidaciousMBR> Even if I keep trying to plug USB stuff into it
2014-12-05T16:49:59 < dongs> Insertion and withdrawal speed :
2014-12-05T16:49:59 < dongs> 25mm/minute.
2014-12-05T16:50:02 < dongs> this is in hdmi spec
2014-12-05T16:50:17 < zyp> what
2014-12-05T16:50:34 < dongs> under connection mechanical performance
2014-12-05T16:50:36 < zyp> so less than 0.5mm/second?
2014-12-05T16:50:38 < dongs> er connector
2014-12-05T16:50:48 < dongs> guess so
2014-12-05T16:50:52 < zyp> I don't get it
2014-12-05T16:50:54 < dongs> so you shouldnt be yanking on it
2014-12-05T16:51:13 < dongs> Insertion force 44.1N {4.5kgf} maximum
2014-12-05T16:51:16 < zyp> sure, but at that rate you'd spend half a minute inserting a hdmi plug
2014-12-05T16:52:04 < dongs> Drop onto a horizontal concrete surface

2014-12-05T20:28:02 < qyx_> in summary there is 0.4dB insertion loss, which i interpret that signal will be lower by 0.4dB
2014-12-05T20:28:13 < qyx_> and later in graphs it is specified with negative values
2014-12-05T20:28:35 < qyx_> now i don't know if actual loss is 0.4 or -0.4

2014-12-05T21:30:33 < Laurenceb_> this is something that has confused me for a long time
2014-12-05T21:30:38 < ds2> the ADC drivers suck. My advice - write your own driver.
2014-12-05T21:30:46 < Steffanx> No butane solder iron, wires, and a spare board you can flash the bmp fw on zyp?
2014-12-05T21:31:20 < Laurenceb_> what is the process between adding a device to cape manager and it appearing in /dev  ?
2014-12-05T21:31:22 < ds2> Just so you don't think I am blowing smoke - i am still using a 3.2 kernel w/o device tree. had to write a driver for the ADC to do audio in

2014-12-05T21:32:27 < ds2> that will "create" the device from the DT point of view. A driver is then expected to be matched up and attached to it.

2014-12-05T21:38:26 < ds2> why are you modifying that?
2014-12-05T21:38:30 < ds2> do you have an odd ball pinmux?
2014-12-05T21:39:39 < ds2> all that fragment does is set the pinmux
2014-12-05T21:39:46 < Laurenceb_> i only want to use USART4 TX
2014-12-05T21:40:00 < Laurenceb_> for some reason it wont load reliably now
2014-12-05T21:40:03 < Laurenceb_> i loaded it once

2014-12-05T22:52:43 < karlp> dongs, mr paypal, is there anyway to just pay someone using paypal, without having to make an account?
2014-12-05T22:53:05 < karlp> the standard eshopping payment processor protal thing used to have an option of "just paying" but it seems to be gone (at least on this vendor)
2014-12-05T22:53:09 < karlp> fucking paypal
2014-12-05T22:56:22 < jpa-> should be available, but who knows
2014-12-05T22:56:51 < jpa-> just use my account, you'll probably guess the password
2014-12-05T22:57:51 < karlp> oh, I _have_ an account, skype offered zero alternatives, but I refuse to use it if at all humanly possible
2014-12-05T22:58:32 < jpa-> because?
2014-12-05T22:58:52 < karlp> because they're cunts and I don't like their business model of holding people's money
2014-12-05T22:59:09 < karlp> I want shops to use payment processors, not get lulled into handing over massive cuts to paypal
2014-12-05T22:59:15 < zyp> so you don't like banks either?
2014-12-05T22:59:26 < zyp> heh
2014-12-05T22:59:34 < karlp> banks have much more regulation than paypal does
2014-12-05T22:59:49 < karlp> look at dongs, he can't even get his money out of paypal, has to use it as a slush fund
2014-12-05T23:00:04 < zyp> I've done comparisons, paypal fees are not significantly worse than payment processors tend to be
2014-12-05T23:00:06 < karlp> they have repeatedly decided to hold funds "just because"
2014-12-05T23:00:15 < jpa-> isn't the whole payment card industry a massive fraud?
2014-12-05T23:00:18 < zyp> stripe for instance has around the same fee level as paypal
2014-12-05T23:00:19 < karlp> sure,
2014-12-05T23:00:29 < karlp> but I'd rather not have visa/mastercard -and_ paypal involved
2014-12-05T23:00:32 < jpa-> like it really costs 1-2% to pass around 100 bytes of data
2014-12-05T23:00:41 < zyp> and I like the convenience of paying with paypal
2014-12-05T23:01:00 < karlp> well, good for you guys :)
2014-12-05T23:01:08 < zyp> enter password -> done
2014-12-05T23:01:23 < zyp> instead of entering a bunch of card data that can be abused to draw more money from my card
2014-12-05T23:01:33 < zyp> not that I'm concerned about abuse, but I'm lazy
2014-12-05T23:01:55 < jpa-> same for me
2014-12-05T23:02:06 < karlp> my cards have been skimmed, but it wasn't from online forms
2014-12-05T23:02:19 < zyp> and as a buyer, it's not my money that gets frozen
2014-12-05T23:02:28 < karlp> yeah, well, I dont' want to support how they treat sellers
2014-12-05T23:02:40 < jpa-> ebay is pretty harsh to sellers also
2014-12-05T23:02:40 < zyp> though, I've had $2500 sitting without being significantly concerned about that either
2014-12-05T23:02:44 < karlp> theyv'e got too many horror stories for me to desire to encourage them
2014-12-05T23:03:15 < karlp> jpa-: indeed
2014-12-05T23:03:17 < jpa-> karlp: why not let the sellers decide for themselves? it's not like they cannot offer paypal *and* some other option?
2014-12-05T23:03:53 < zyp> I'll let you know when my account gets frozen so you can laugh at me :p
2014-12-05T23:04:26 < karlp> jpa-: seller can decide, sure, but in the past, they could choose to use paypal for their purposes, but it didn't force me to get a paypal account

2014-12-06T04:16:14 < dongs> rk[1]: define "alternatives", tehre's a bunch of chinese chips that do ~similar things
2014-12-06T04:16:15 < emeb_mac> plus whatever blanking is in there no doubt
2014-12-06T04:16:48 < dongs> Often PLLs need to translate (or convert) between noninteger
2014-12-06T04:16:48 < dongs> related frequencies as in the case of a timing generator that needs to synchronize to an NTSC HSYNC rate
2014-12-06T04:16:51 < dongs> and generate an HD-SDI sample clock for an SDI serializer (e.g., locking to 15.75/1.001 kHz to generate 74.25/
2014-12-06T04:16:54 < dongs> 1.001 MHz requires a multiplication ratio of 4719000/1001 or 4.71428571428571).

2014-12-06T04:18:58 < rk[1]> the reason i need PWM is for brightness control, because i am driving a bunch of RGB leds, and the only way to get the color spectrum is through varying degrees of brightness per pin

2014-12-06T04:19:56 < dongs> anyway all those are designed for cascading
2014-12-06T04:20:19 < dongs> or you can just use WS2812/etc leds.

2014-12-06T04:21:36 < rk[1]> thanks:)
2014-12-06T04:21:54 < rk[1]> that is one trouble i often have when trying to build circuits, is know what chips i need to use to get what i want done
2014-12-06T04:22:19 < rk[1]> so you can daisychain the MY9221?
2014-12-06T04:22:25 < dongs> yes, just like tlc
2014-12-06T04:22:54 < dongs> but it uses some weird DDR data input, so you won't be able to use SPI (without hax) to drive it
2014-12-06T04:23:29 < rk[1]> hmm.
2014-12-06T04:23:37 < rk[1]> what MCU are you using to drive the MY9221?
2014-12-06T04:23:44 < dongs> just bitbang on stm32.
2014-12-06T04:24:04 < dongs> also tlc59282 is dirt cheap but you will need to do your own pwm for brigthness
2014-12-06T04:24:11 < dongs> (and probably need cpld/fpga for timing that stuff.
2014-12-06T04:24:12 < rk[1]> right on. currently i am just using an atmega328
2014-12-06T04:24:41 < rk[1]> as my program itself is simple; though i will probably end up using something a little more capable as time progresses
2014-12-06T04:25:37 < rk[1]> yeah, that is my only issue with the 5940 is the chip is $6 and i need a lot of them.
2014-12-06T04:26:07 < dongs> you might be able to do 1/x scan and remove some chips. but stuff might flicker
2014-12-06T04:26:13 < rk[1]> but i am also just curious about alternatives, as it always seems worth it to try different chips for this and that
2014-12-06T04:26:29 < rk[1]> yeah, i was trying to think if i could come up with something clever
2014-12-06T04:27:06 < rk[1]> i need more experience to be clever, so i think ima just order a bunch of the TLC5940s at some point here. or maybe try the MY9221
2014-12-06T04:27:14 < dongs> ws2811 (standalone driver ic) is very cheap even if you need one per led.
2014-12-06T04:27:40 < dongs> or was it ws2801? something liek that
2014-12-06T04:27:45 < dongs> there's also SPI version of that.
2014-12-06T04:27:59 < rk[1]> ah interesting 3 channel constant current
2014-12-06T04:28:11 < dongs> WS2801
2014-12-06T04:28:16 < dongs> thats the SPI one
2014-12-06T04:28:18 < dongs> cascade them
2014-12-06T04:28:24 < dongs> htey're like .15c/ea from china
2014-12-06T04:28:32 < dongs> or less probly now
2014-12-06T04:28:44 < rk[1]> the nice thing for me about the TLC5940, was that it only needs 4 PWM pins for input which the atmega328 has and then i can drive essentially infinite amount of leds from that
2014-12-06T04:29:01 < rk[1]> as OK, so you can cascade that one just like the TI chip
2014-12-06T04:29:04 < dongs> pwm? i thought it was just SPI
2014-12-06T04:29:06 < rk[1]> neat, i should definitely look in to that.
2014-12-06T04:29:09 < dongs> so clk+data+latch
2014-12-06T04:30:04 < rk[1]> ah yeah, i htink your right
2014-12-06T04:30:14 < rk[1]> still 4 input pins, gives me all the PWM output pins i need
2014-12-06T04:32:26 < rk[1]> what kinda physical limits are there on chaining those WS2801 s?
2014-12-06T04:32:57 < dongs> none that you would hit
2014-12-06T04:33:09 < dongs> i've made strings of 1k of them
2014-12-06T04:33:14 < dongs> on outdoor signs
2014-12-06T04:33:19 < rk[1]> 1k... seriously awesome!
2014-12-06T04:33:28 < rk[1]> my personal end goal is
2014-12-06T04:34:00 < rk[1]> https://www.youtube.com/watch?v=f1YNyQqbiF0
2014-12-06T04:34:11 < rk[1]> 32k...
2014-12-06T04:34:29 < dongs> it might be cheaper to just buy it from them
2014-12-06T04:46:47 < rk[1]> sure as i said, that would be an "end" goal. as in maybe down the line i have enough experience to come up with a better way to do that.
2014-12-06T04:47:03 < rk[1]> anyhow, there are several products where i want to drive a bunch of leds.
2014-12-06T04:47:13 < rk[1]> that WS2801 chip seems probably exactly what i am looking for thanks!
2014-12-06T04:47:33 < rk[1]> only sad thing is it isn't exact a breadboard chip, which i like for playing around
2014-12-06T04:47:45 < rk[1]> thanks again!!
2014-12-06T04:47:58 < dongs> eh

2014-12-06T04:49:44 < GargantuaSauce> cheaper elsewhere probably, i just took first google result
2014-12-06T04:49:46 < dongs> you can get like 20 of those for $2 from ebay

2014-12-06T09:13:23 < dongs> and accuracy seems on par wiht peak stuff and replaces both with a single tool, so im happy.

2014-12-06T14:17:48 < bezoka> Is hard to write in asm for stm32?
2014-12-06T14:18:04 < dongs> hello beaky
2014-12-06T14:18:10 < kakeman> nope
2014-12-06T14:18:15 < dongs> STM32 doesn't have ASM. its standard thumb2 asm.
2014-12-06T14:21:16 < bezoka> What's differents?
2014-12-06T14:22:03 < dongs> nothing
2014-12-06T14:28:26 < kakeman> it has instruction set of arm core used
2014-12-06T14:29:43 < qyx_> karlp: worked?
2014-12-06T14:29:51 < kakeman> I believe in most cases it's ARMv7
2014-12-06T14:30:04 < qyx_> although theres nothing that should prevent it from wroking
2014-12-06T14:32:08 < qyx_> *would maybe
2014-12-06T14:36:23 < bezoka> is good idea to write for stm32 in asm, or compilers are so good for write in asm?
2014-12-06T14:40:16 < dongs> no
2014-12-06T14:40:19 < dongs> its fucking retarded
2014-12-06T14:40:25 < dongs> infact, real compilers dont even let you mix asm/C
2014-12-06T14:40:37 < mitrax_> bezoka: nowadays compilers usually generate very optimized code, there's no point in writing in asm
2014-12-06T14:40:39 < dongs> because chances of you writing better code than compiler are very low
2014-12-06T14:40:50 < bezoka> mitrax_: thanks a lot

2014-12-06T14:43:04 < dongs> see my comment.
2014-12-06T14:43:14 < bezoka> yea, I know
2014-12-06T14:43:50 < mitrax_> bezoka: even for small project that would be a giant waste of time anyway, like digging a hole with a spoon
2014-12-06T14:44:08 < kakeman> when you use debugger you see how tight asm compiler makes
2014-12-06T14:44:13 < dongs> or installing lunix on desktop
2014-12-06T14:44:53 < kakeman> there is no way you could compete with it
2014-12-06T14:44:53 < bezoka> linux on desktop? why not? :D
2014-12-06T14:45:57 < bezoka> I will write in c
2014-12-06T14:50:13 < dongs> lunix on desktop = why yes, thre's no reason.

2014-12-06T16:48:16 < decimad2> hrmmm, so I tested setting a variable pin output using bsrr atomically and odr read-modify-write, they both end up taking 4 instructions with a total of 12 byte (+ shared register setup). Is there any point in using odr? :D
2014-12-06T16:49:45 < jpa-> not for setting a single pin
2014-12-06T16:50:01 < jpa-> but if you want to e.g. stream data out of GPIO port as a whole, ODR is nice
2014-12-06T16:50:26 < jpa-> dunno why your bsrr set would take so many instructions

2014-12-06T17:27:26 < zyp> travelling with a pal, he got held up for a few minutes because linux wouldn't fucking wait
2014-12-06T17:27:57 < zyp> so we missed the airport train departure we should have got on, and arrived at the airport too late

2014-12-06T17:38:15 < Steffanx> had the print the ticket or something?
2014-12-06T17:38:28 < zyp> no
2014-12-06T17:38:33 < zyp> we don't fly ryanair :p
2014-12-06T17:39:04 < jpa-> did he manage to print it in just a few minutes?
2014-12-06T17:39:16 < zyp> just a few minutes too many
2014-12-06T17:39:27 < jpa-> so 93 minutes total
2014-12-06T17:39:30 < jpa-> sounds about right
2014-12-06T17:39:44 < zyp> what?
2014-12-06T17:39:49 < Steffanx> cups on os x tends to work pretty well though.
2014-12-06T17:39:51 < BrainDamage> i'm impressed cups worked at all
2014-12-06T17:39:57 < zyp> Steffanx, yeah
2014-12-06T17:40:01 < BrainDamage> cups is partially funded by apple
2014-12-06T17:40:27 < Steffanx> The last time it didnt work for me was with some lunix based network printer.
2014-12-06T17:41:38 < Steffanx> Anyway, now you have to reschedule the flight or .. new ticket?
2014-12-06T17:42:50 < zyp> new ticket, departure in an hour
2014-12-06T17:43:51 < zyp> and luckily the return ticket didn't get invalidated
2014-12-06T17:45:04 < qyx_> heh cups

2014-12-06T19:59:55 < TheSeven> I'm wondering if that's a software USB implementation (doesn't seem so) or (much more likely) a chip that has undocumented features

2014-12-06T20:06:44 < TheSeven> mitrax_: no, the USB connector is connected to pins 32/33 (on 48pin package, that's PA11/PA12, where USB is on F103) through 27R resistors
2014-12-06T20:06:55 < TheSeven> I'm talking about an STlink clone btw

2014-12-07T01:10:17 < TheSeven> is there an open source tool that can flash st-links? (i.e. update firmware)
2014-12-07T01:10:36 < TheSeven> I mean through their builtin DFU mode, not through SWD of the STM32 used in the ST-link
2014-12-07T01:11:06 < zyp> dfu-util will do that
2014-12-07T01:21:09 < TheSeven> despite that crypto crap?
2014-12-07T01:21:36 < TheSeven> I read something that the upload has to be encrypted with a device specific key
2014-12-07T01:22:02 < zyp> what?
2014-12-07T01:22:15 < zyp> is this a crypto-capable stm32 variant?
2014-12-07T01:22:26 < zyp> the normal stm32 variants at least don't have any such requirements
2014-12-07T01:22:43 < zyp> you just write a plain binary directly to a given flash addr
2014-12-07T01:23:17 < TheSeven> IIUC this is not the STM32 ROM bootloader DFU mode but some on-flash crypto DFU bootloader used in there
2014-12-07T01:23:50 < zyp> well, you asked about the builtin DFU mode
2014-12-07T01:24:04 < TheSeven> of the ST link, not STM32 inside it ;)
2014-12-07T01:24:10 < zyp> oh
2014-12-07T01:24:12 < zyp> right
2014-12-07T01:24:23 < zyp> sorry, I misread your question
2014-12-07T01:24:37  * TheSeven needs to fix the firmware of a bad stlink clone :P
2014-12-07T01:37:39 < Steffanx> iirc there was someone working on it, but never finished it TheSeven
2014-12-07T01:38:17 < Steffanx> probably because it turned out to be easier to use the uart bootloader
2014-12-07T01:39:09 < Steffanx> or easier to reprogram using another programmer
2014-12-07T01:52:28 < aadamson> anyone know if stm32cubemx shows you if a pin is 5v tolerant or not? and how?
2014-12-07T01:53:17 < aadamson> hmm... doesn't appear obvious
2014-12-07T01:54:14 < upgrdman> fuck. meant to power a usb device (wireless keyboard dongle) with +5V. learned that my analog discovery's psu tool supplies +/-5V by default. the dongle did not appreciate 10V :( burned smell
2014-12-07T01:54:30 < englishman> aadamson: just the datasheet i think
2014-12-07T01:54:39 < englishman> but on qfp48 its just the PCx pins
2014-12-07T01:55:26 < aadamson> I don't think that's true
2014-12-07T01:55:33 < aadamson> PB0 wasn't 5v on the l1
2014-12-07T01:55:38 < aadamson> for example
2014-12-07T01:56:02 < englishman> hmh didnt know that
2014-12-07T01:57:12 < aadamson> actually lots of the PA and PB pins are not
2014-12-07T01:57:15 < aadamson> on the L1
2014-12-07T01:57:30 < aadamson> pretty sure same on the F3 (but those are the only two I'm messing with at the moment)
2014-12-07T01:58:04 < aadamson> PA3,4,5  for example are not
2014-12-07T01:58:07 < aadamson> (3v3 only)
2014-12-07T01:58:15 < englishman> hmm yeah
2014-12-07T01:59:00 < aadamson> and if you are pulling a fet up on the pin side with a 5v buss, ya kinda need a pin that is 5v tolerant :0
2014-12-07T01:59:07 < englishman> nope just looks like datasheet table
2014-12-07T01:59:38 < aadamson> yeah I go by that only the FT's are 5v
2014-12-07T01:59:41 < englishman> oh yeah so i went to an st seminar on thursday about L0
2014-12-07T01:59:46 < englishman> it was pretty cool but
2014-12-07T02:00:00 < aadamson> *pregnant pause*....
2014-12-07T02:00:11 < englishman> nobody at st uses timecube apparently.
2014-12-07T02:00:26 < aadamson> hehe does that surprise anyone, it's a POS
2014-12-07T02:00:38 < englishman> and the marketing guy was like "yeah we are trying to get updates out quarterly"
2014-12-07T02:00:40 < aadamson> I only use it for PIN assignments
2014-12-07T02:00:47 < englishman> "but until then it's quite difficult"
2014-12-07T02:00:51 < englishman> or something
2014-12-07T02:00:56 < englishman> yeah like microxplorer
2014-12-07T02:01:32 < aadamson> yeah, I pretty much don't use that anymore, just timecube for the same, now that it will do power consumption for the l0/l1
2014-12-07T02:01:47 < englishman> L0 has some cool stuff i gotta say
2014-12-07T02:01:53 < aadamson> yeah
2014-12-07T02:02:03 < aadamson> just not enough flash/ram for me just yet
2014-12-07T02:02:11 < aadamson> but they have some new ones coming... and I want to see the L4
2014-12-07T02:03:13 < englishman> they didnt mention L4 at all, wasnt in their roadmap, just F7
2014-12-07T02:03:32 < aadamson> yeah I heard it from a friend in EU... L version of M4
2014-12-07T02:03:37 < englishman> cool
2014-12-07T02:03:44 < aadamson> or should I say ULP version of M4
2014-12-07T02:04:21 < englishman> 64k not enough for a HAB?
2014-12-07T02:05:02 < aadamson> well, depends, when you are doing ISS predict, and all the float tables for lat/lon geofence... NO
2014-12-07T02:05:09 < aadamson> I can fit just the code in about 24K :)
2014-12-07T02:05:16 < aadamson> without the above
2014-12-07T02:05:26 < aadamson> but those are HUGE when you want them
2014-12-07T02:05:36 < englishman> flash chips are mega cheap for those kind of static tables tho?
2014-12-07T02:05:49 < aadamson> yeah I know...
2014-12-07T02:06:14 < aadamson> but I'm already at 8mhz and < 1mA on the process
2014-12-07T02:06:26 < englishman> i just looked up this morning 32Mb 60c in singles
2014-12-07T02:06:26 < aadamson> and it's not the processor that's the power pig so really no need for the L0
2014-12-07T02:06:47 < aadamson> what's that a 4k byte part?
2014-12-07T02:06:55 < englishman> 32Mb...
2014-12-07T02:07:04 < aadamson> oh missed that above...

2014-12-07T07:49:11 < emeb_mac> hmmm...
2014-12-07T07:49:37 < emeb_mac> generally good, but the -80dBc/Hz @ 10kHz seems a bit high
2014-12-07T07:50:33 < emeb_mac> not bad for the price though - $1500 is pretty good
2014-12-07T07:51:55 < emeb_mac> yeah
2014-12-07T07:52:03 < emeb_mac> that's useful
2014-12-07T07:52:10 < emeb_mac> and the phase noise is a lot better
2014-12-07T07:52:28 < emeb_mac> right
2014-12-07T07:52:49 < emeb_mac> not too different from my agilent E4402
2014-12-07T07:52:57 < emeb_mac> with better RBW
2014-12-07T07:53:25 < emeb_mac> 1st one is good for price but might be a bit noisy and low freq
2014-12-07T07:53:57 < emeb_mac> really depends on what you *need*
2014-12-07T07:54:20 < emeb_mac> if you can get by with 1.5GHz then #1 would probably be OK
2014-12-07T07:54:53 < emeb_mac> then #1 should be fine
2014-12-07T07:55:04 < emeb_mac> ya
2014-12-07T07:55:23 < emeb_mac> I prefer Agilent over Tek

2014-12-07T07:56:59 < emeb_mac> I bet you could get one on ebay etc for better price
2014-12-07T07:57:35 < emeb_mac> hard to say - depends on condition
2014-12-07T07:59:32 < emeb_mac> well, buying new you have better chance at meeting specs and return if it's bad

2014-12-07T08:13:09 < emeb_mac> eh - probably works fine with USB2
2014-12-07T08:13:23 < upgrdman> good
2014-12-07T08:13:45 < emeb_mac> N connector for inpu
2014-12-07T08:13:56 < emeb_mac> "high quality" :)
2014-12-07T08:14:15 < upgrdman> R2COM: TSPB noticed some annoying spurs but the device was well within spec. watch the TSPB video before buying
2014-12-07T08:14:38 < emeb_mac> downside - what if they stop updating the software & MS OS keeps advancing
2014-12-07T08:15:00 < emeb_mac> my Agilient E4402 works on its own
2014-12-07T08:15:03 < upgrdman> its an hour long, but very good:  https://www.youtube.com/watch?v=GDcuRTOCj_s&list=UUKxRARSpahF1Mt-2vbPug-g
2014-12-07T08:15:15 < emeb_mac> but the interface software only works on Win XP
2014-12-07T08:15:49 < upgrdman> emeb_mac: VMs are a thing. but ya, a valid point.
2014-12-07T08:15:53 < emeb_mac> but if you've got a box that needs a PC to work then it's always dependent on OS
2014-12-07T08:16:28 < emeb_mac> dunno how well Tek keeps up with MS
2014-12-07T08:17:12 < upgrdman> that tek spec an just came out, so i doubt tek will drop new os support within the next couple years
2014-12-07T08:17:50  * emeb_mac is old
2014-12-07T08:18:01 < emeb_mac> I've only had the E4402 for about 8yrs
2014-12-07T08:18:14 < emeb_mac> but the SW is already out of date
2014-12-07T08:18:31 < emeb_mac> had to write my own app to do screengrabs
2014-12-07T08:18:39 < emeb_mac> to run on Win 7
2014-12-07T08:18:52 < upgrdman> in 25 years we'll all be buying some awesome DC to THz spec ans
2014-12-07T08:19:05 < emeb_mac> upgrdman: you wish :)
2014-12-07T08:19:12 < upgrdman> i do
2014-12-07T08:20:54 < englishman> this is a great thread http://www.reddit.com/r/ECE/comments/2ohizw/are_maxim_still_shitlisted_for_lead_times/
2014-12-07T08:22:44 < englishman> cool part
2014-12-07T08:27:30 < emeb_mac> that would be handy
2014-12-07T08:27:47 < emeb_mac> I use a sweeper and SA that are totally asynch
2014-12-07T08:27:58 < emeb_mac> just put it on max hold and let it run a while
2014-12-07T08:28:10 < emeb_mac> eventually it hits all the freqs
2014-12-07T08:28:59 < emeb_mac> instek is reasonably good - know a lot of folks who have their scopes
2014-12-07T08:33:09 < emeb_mac> I've always gotten by w/o tracking or any kind of sync
2014-12-07T08:33:48 < emeb_mac> SA and sig gen will always intersect "somewhere" and max hold will grab it
2014-12-07T08:35:38 < emeb_mac> theoretically TG freq sweep is in sync with SA sweep
2014-12-07T08:35:48 < emeb_mac> so you get full results in one sweep
2014-12-07T08:36:07 < emeb_mac> my way (asynch) requires many sweeps to fill in the blanks
2014-12-07T08:36:15 < emeb_mac> yep
2014-12-07T08:36:31 < emeb_mac> just time
2014-12-07T08:36:55 < emeb_mac> yeah
2014-12-07T08:37:26 < emeb_mac> I've always been able to put up with it.
2014-12-07T08:37:45 < emeb_mac> but then I'm not doing production testing with constraints
2014-12-07T08:37:48 < emeb_mac> (on time)
2014-12-07T08:40:37 < emeb_mac> hah
2014-12-07T08:40:53 < emeb_mac> amazon = lolwhut
2014-12-07T08:44:57 < emeb_mac> crappy RBW
2014-12-07T08:45:04 < emeb_mac> 30kHz isn't great
2014-12-07T08:45:33 < emeb_mac> my E4402 is 1kHz RBW and that's sometimes a PITA
2014-12-07T08:46:21 < emeb_mac> you want RBW to go as small as possible
2014-12-07T08:46:28 < emeb_mac> 100Hz is not bad

2014-12-07T10:17:01 < jadew> apparently they're making use of an ASIC specifically made for the job, which is why they're cheaper

2014-12-07T10:24:02 < jadew> yeah
2014-12-07T10:30:06 < dymk> interesting, so these chips have X timers, but each timer has Y channels

2014-12-07T11:31:13 < jpa-> yeah, pretty normal and also smart
2014-12-07T11:31:26 < jpa-> because often you have multiple events (say, motor drive pulses) that you want to synchronize
2014-12-07T11:31:50 < dongs> R2COM: ya it works good if you dont need button sense on mcu and just want on/off

2014-12-07T11:33:34 < dongs> err page 4
2014-12-07T11:36:47 < dongs> so its lineaR?
2014-12-07T11:38:09 < dongs> no the skyworks charger
2014-12-07T11:38:53 < dongs> theres linear and switching charger
2014-12-07T11:39:54 < dongs> ah that thing is like wat, 150mA max charge?
2014-12-07T11:39:58 < dongs> o wait sais 500
2014-12-07T11:39:58 < dongs> k
2014-12-07T11:42:01 < qyx_> its 95% linear if theres no inductor
2014-12-07T11:43:04 < dongs> yes, switching ones will have inductor
2014-12-07T11:43:05 < qyx_> 8tfsoj? wtf

2014-12-07T11:45:45 < dongs> qyx, nice
2014-12-07T11:46:00 < dongs> but theres only like 2 choices for switching ones
2014-12-07T11:46:06 < dongs> i have to ask chinagirl tomrorw which ones are availble
2014-12-07T11:46:17 < dongs> ill need to charge like 10-20Wh battery at > 1A
2014-12-07T11:46:21 < dongs> and most linear chargers will suck at that

2014-12-07T18:33:26 < Tekkkz> hello
2014-12-07T18:33:38 < Tekkkz> i have a question:
2014-12-07T18:33:40 < zyp> dongs, my guess: more than practically possible
2014-12-07T18:33:58 < Tekkkz> im programming my st32f4 disco in c, and hvae following problem:
2014-12-07T18:34:03 < dongs> zyp, really?
2014-12-07T18:34:07 < kakeman> are those glass :o
2014-12-07T18:34:16 < kakeman> I think so too
2014-12-07T18:35:38 < dongs> im taking apart old hitachi drive that died in my raid
2014-12-07T18:35:44 < dongs> those should be using glass platters
2014-12-07T18:37:22 < decimad> dongs: since the bits are magnetic and magnets attract each other, it obviously depends on the amount of bits stored!

2014-12-07T18:39:03 < Tekkkz> this is my curciut: http://i.imgur.com/ZZDo2OZ.png ; im using this lib to get the state of the button: http://mikrocontroller.bplaced.net/wordpress/?page_id=456 ; im using the UB_Button_OnPressed at my main loop but and increment a value with ++; but it reaches instant the maximum of an 16 bit integer, why?
2014-12-07T18:39:56 < dongs> im guessing bouncve
2014-12-07T18:40:12 < zyp> I'm guessing shitty code
2014-12-07T18:40:19 < dongs> that too
2014-12-07T18:40:20 < Tekkkz> ?
2014-12-07T18:40:23 < zyp> you shouldn't get 64k bounces in an instant
2014-12-07T18:40:29 < decimad> The button toggles between high and high?
2014-12-07T18:40:35 < Tekkkz> the lib should unbounce it i thing
2014-12-07T18:41:17 < Tekkkz> no, pull down is activated so shouldnt it toggle between down and high?
2014-12-07T18:41:27 < decimad> The image says pull up
2014-12-07T18:41:37 < zyp> actually, my guess is that you're using the function wrong
2014-12-07T18:41:53 < zyp> like if(pressed) { cnt++; }
2014-12-07T18:41:59 < Tekkkz> sorry im using DOWN; yes^^
2014-12-07T18:42:02 < Tekkkz> is it wrong?
2014-12-07T18:42:16 < decimad> pull down is okay
2014-12-07T18:42:24 < jpa-> dongs: to explode a glass disc, the outer rim would have to go at around 1km/s; so for e.g. 8cm diameter disc, around 200 000 RPM
2014-12-07T18:42:24 < Tekkkz> i mean with if
2014-12-07T18:42:41 < Tekkkz> zyp: why is it wrong?
2014-12-07T18:42:43 < zyp> Tekkkz, you're counting continously as long as the button is pressed

2014-12-07T18:43:22 < Tekkkz> ahh hm... how can i solve this?
2014-12-07T18:43:48 < decimad> With the help of brain
2014-12-07T18:43:48 < zyp> only count it if it was not pressed last time you checked
2014-12-07T18:44:05 < Tekkkz> ah nono it should count up the long i press
2014-12-07T18:44:12 < Tekkkz> nut not instant to the "end"
2014-12-07T18:44:24 < dongs> jpa-: ,fuck
2014-12-07T18:44:37 < dongs> jpa-: i think the esc will shit out at ~60k rpm
2014-12-07T18:44:42 < zyp> Tekkkz, so you actually want to count the length of a press?
2014-12-07T18:45:14 < zyp> not the number of presses?
2014-12-07T18:45:59 < dongs> heh when i needed button press shit i tried copypasting other peoples stuff
2014-12-07T18:46:01 < dongs> and it al lsucked
2014-12-07T18:46:05 < dongs> so i ended up writing my own shitty stuff
2014-12-07T18:46:16 < Tekkkz> yes zyp
2014-12-07T18:46:29 < madist> own shit always smells better than other's shit.
2014-12-07T18:46:43 < zyp> Tekkkz, well
2014-12-07T18:47:02 < zyp> what you're doing now is counting how many times you've checked and it was pressed
2014-12-07T18:47:09 < jpa-> dongs: the more modern aluminum discs would explode at 110 kRPM; a plastic disc of same size would be at 50 kRPM
2014-12-07T18:47:10 < decimad> 16 Bit = 65536 cycles max... STM32F4 = 168000000 per second
2014-12-07T18:47:19 < zyp> and checking 64k times takes a fraction of a second
2014-12-07T18:47:38 < englishman> dongs: that chip from r2com will let you do longpress stuff if you hook it up right
2014-12-07T18:47:41 < zyp> and doing this with a counter at all is dumb
2014-12-07T18:47:54 < dongs> englishman: you can try  innovating with it and see.
2014-12-07T18:48:01 < dongs> ill stick with my working solution with cheap passives
2014-12-07T18:48:08 < englishman> oh nvm then
2014-12-07T18:48:13 < englishman> if you got something that works
2014-12-07T18:48:24 < zyp> what you should do is detect only when the button is pressed and when it's released, and store the timestamp for each, then subtract to get the difference
2014-12-07T18:48:36 < dongs> yes i got something that works very well
2014-12-07T18:48:49 < englishman> cool
2014-12-07T18:48:54 < Tekkkz> oh shit i dont know what i should do^^

2014-12-07T19:16:28 < madist> how does supply voltage variation affect the working of an MCU ? e.g. if I run a 3.3V MCU at 2.x volts what can I expect to work differently ?
2014-12-07T19:18:19 < englishman> what does the datasheet say?
2014-12-07T19:18:19 < bvernoux> madist: GPIO will be slower
2014-12-07T19:18:22 < zyp> first of all, check the supply range specified
2014-12-07T19:18:27 < bvernoux> madist: and CPU will consume less current
2014-12-07T19:18:36 < bvernoux> madist: also max freq will be lower
2014-12-07T19:19:10 < madist> englishman: do datasheets specify anythig other than limits for voltage ?
2014-12-07T19:19:23 < emeb> re Maxim - I've heard the same thing from a guy who used to do field apps for them.
2014-12-07T19:19:27 < bvernoux> madist: also at 2V it's possible you cannot flash internal MCU flash memory ...
2014-12-07T19:19:47 < madist> bvernoux: assume 2.x is over the minimum specified voltage.
2014-12-07T19:19:50 < englishman> L0 runs to 1.65V, pretty sure flash would work fine at 2V
2014-12-07T19:20:01 < bvernoux> I was not speaking about L0
2014-12-07T19:20:06 < zyp> l0 has a low power flash
2014-12-07T19:20:08 < bvernoux> as L0 is for low power
2014-12-07T19:20:13 < englishman> you didn't qualify what you were speaking about at all
2014-12-07T19:20:20 < bvernoux> but more about other family like F1 to F4
2014-12-07T19:20:28 < bvernoux> which are commonly 3.3V
2014-12-07T19:20:36 < zyp> the F4 flash manual specifies different flashing methods for various voltage ranges
2014-12-07T19:20:42 < kakeman> do you know any long life OTP memmory devices that are widely available?
2014-12-07T19:21:11 < jpa-> what is long life?
2014-12-07T19:21:13 < madist> OTP memories are always long life.
2014-12-07T19:21:14 < zyp> you need to have over a given supply voltage to be able to do 32-bit writes on f4
2014-12-07T19:21:18 < dongs> kakeman: yes, http://i.stack.imgur.com/dPIzd.jpg
2014-12-07T19:21:26 < zyp> at lower voltages you need to resort to 16- or 8-bit writes
2014-12-07T19:21:36 < madist> that's interesting.
2014-12-07T19:21:40 < bvernoux> life of OTP is 1 time ;)
2014-12-07T19:21:48 < madist> I think he meant retention.
2014-12-07T19:21:51 < zyp> (and for real fast production line flashing, there's a separate vprog supply that'll allow 64-bit writes)
2014-12-07T19:22:00 < bvernoux> retention is often > 10years
2014-12-07T19:22:05 < bvernoux> even 30 years
2014-12-07T19:22:11 < bvernoux> but it's simulated ;)
2014-12-07T19:22:18 < kakeman> jpa-: talking about minimum of 20-30 guaranteed retention
2014-12-07T19:22:21 < madist> yeah that's what I answered to. retention is never an issue in OTP.
2014-12-07T19:22:25 < kakeman> 20-30a
2014-12-07T19:23:00 < dongs> kakeman: make a ROM with dip switches
2014-12-07T19:23:01 < bvernoux> anyway don't rely on 20 or 30 years ;)
2014-12-07T19:23:09 < bvernoux> and replace after 10 years is a good advice
2014-12-07T19:23:22 < kakeman> make it replaceable hey
2014-12-07T19:23:27 < kakeman> it's better idea
2014-12-07T19:23:41 < kakeman> use just eeprom
2014-12-07T19:23:45 < jpa-> kakeman: many SPI eeprom chips promise hundreds of years
2014-12-07T19:23:47 < bvernoux> yes or replace the whole board it's even better ;)

2014-12-07T19:24:29 < bvernoux> anyway it depends on peaks too
2014-12-07T19:24:39 < BrainDamage> you can get few k years from those http://www.newscientist.com/data/images/ns/cms/dn17405/dn17405-1_300.jpg
2014-12-07T19:24:43 < bvernoux> in environnement if they have bad regulated power supply they could quickly die
2014-12-07T19:24:54 < madist> not in an acidic environment.
2014-12-07T19:24:54 < Taxman> why is this eeprom so expensive?
2014-12-07T19:24:57 < bvernoux> 10 to 30years is with perfect conditions
2014-12-07T19:25:04 < madist> or anywhere in the middle east.
2014-12-07T19:25:23 < jpa-> Taxman: because it is 3000 pieces, i was lazy and didn't click the "1 piece" link
2014-12-07T19:25:56 < Taxman> no i mean the piece price
2014-12-07T19:26:09 < jpa-> 0.40 USD is expensive? ok
2014-12-07T19:26:11 < Taxman> 31¢ per device

2014-12-07T19:27:13 < englishman> they all cost about the same... 32Mb is like 60c

2014-12-08T00:23:31 < bvernoux> upgrdman: yes I would like to debug the FPGA nb9 ;)
2014-12-08T00:23:57 < bvernoux> it's probably chained JTAG ;)
2014-12-08T00:24:01 < bvernoux> what a mess ;)
2014-12-08T00:25:28 < upgrdman> :)
2014-12-08T00:25:54 < upgrdman> also nice pcb:  http://imagizer.imageshack.us/a/img13/9519/kpo5.jpg
2014-12-08T00:25:54 < bvernoux> I imagine it's the same bitstream in each FPGA ;)
2014-12-08T00:26:13 < bvernoux> ha yes nice about 32layers ;)
2014-12-08T00:27:16 < englishman> is that the next arduino
2014-12-08T00:29:08 < upgrdman> yes
2014-12-08T00:30:54 < bvernoux> Arduino Alpha ;)
2014-12-08T00:41:49 < bvernoux> and now Arduino Gamma
2014-12-08T00:41:49 < bvernoux> http://www.engblaze.com/wp/wp-content/uploads/gallery5.jpg
2014-12-08T00:42:08 < bvernoux> it's to learn wrapping ;)
2014-12-08T00:42:14 < bvernoux> for beginner
2014-12-08T00:47:31 < upgrdman> interfacing with a ps2 keyboard is trivial. anyone interfaced with a usb keyboard? are they easy, or is a big usb stack needed?
2014-12-08T00:48:00 < upgrdman> bvernoux: i have an urge to drag a razor blade along that nest of wires...
2014-12-08T00:48:09 < zyp> upgrdman, should be easy
2014-12-08T00:48:26 < bvernoux> upgrdman: you can always use an FTDI stuff
2014-12-08T00:48:51 < upgrdman> bvernoux: i actually want to write a verilog module for it... for fun.
2014-12-08T00:48:55 < zyp> bvernoux, usb keyboards have a simplified «boot protocol» to allow stuff like bios to have a full hid parser and stuff
2014-12-08T00:49:02 < upgrdman> but if i need a big ass state machine... fuck it
2014-12-08T00:49:17 < zyp> upgrdman*
2014-12-08T00:49:19 < upgrdman> cool
2014-12-08T00:49:26 < upgrdman> will google
2014-12-08T00:49:59 < zyp> you would still need to have a device/config descriptor parser though
2014-12-08T00:50:08 < englishman> afaik stm32 can do hid host, its in timecube
2014-12-08T00:50:12 < englishman> depends on hardware
2014-12-08T00:50:27 < zyp> yes, but only fxx5/7/9
2014-12-08T00:50:37 < englishman> yes
2014-12-08T00:50:38 < zyp> i.e. f107, f2 or f4
2014-12-08T00:50:51 < englishman> fpga tho, dont see why not
2014-12-08T00:51:22 < bvernoux> englishman: doing all from scratch in FPGA is possible check daisho github
2014-12-08T00:51:41 < bvernoux> englishman: about 6months of work for USB2.0 & USB3.0 device stack
2014-12-08T00:52:01 < bvernoux> englishman: and it's fully open source
2014-12-08T00:52:02 < englishman> wouldnt the vendor supply some stuff
2014-12-08T00:52:10 < englishman> i dono im a fpga noob
2014-12-08T00:52:19 < englishman> but that sounds like duplicating efforts if you have to write your own
2014-12-08T00:52:22 < englishman> something the vendor could do better
2014-12-08T00:52:35 < bvernoux> vendor will sell you it ;)
2014-12-08T00:52:49 < bvernoux> it's the problem in FPGA world they are very far from what we have in CPU/MCU
2014-12-08T00:53:28 < zyp> you'd probably want to run some sort of softcpu if you're doing usb on a fpga
2014-12-08T00:53:52 < zyp> most layers of usb is better performed by software than hardware
2014-12-08T00:54:08 < bvernoux> zyp: check daisho project all is Verilog ;)
2014-12-08T00:54:51 < bvernoux> even just to reuse the package is a hard work
2014-12-08T00:57:55 < zyp> bvernoux, as far as I can see, it's device side only
2014-12-08T00:58:17 < zyp> «Planned functionality includes device (not host) operation»
2014-12-08T00:59:03 < bvernoux> yes
2014-12-08T00:59:28 < bvernoux> who need to do host ?
2014-12-08T00:59:42 < bvernoux> interesting stuff are mainly USB device
2014-12-08T00:59:45 < zyp> uh, that's what upgrdman asked for.
2014-12-08T00:59:49 < bvernoux> especially for USB 3.0
2014-12-08T01:00:18 < zyp> upgrdman asked for a way to interface with a usb keybard
2014-12-08T01:00:30 < zyp> since keyboards are devices, you need to be host to interface with them
2014-12-08T01:00:41 < bvernoux> yes it's not for him ;)
2014-12-08T01:00:41 < zyp> so a device only core is rather useless
2014-12-08T01:00:51 < bvernoux> anyway I doubt he want to do all like that
2014-12-08T01:00:52 < upgrdman> :)
2014-12-08T01:00:57 < bvernoux> even if it was host ;)
2014-12-08T01:01:08 < zyp> also true
2014-12-08T01:01:27 < zyp> I mean, I already said it
2014-12-08T01:01:32 < zyp> 23:53:51 < zyp> most layers of usb is better performed by software than hardware
2014-12-08T01:05:24 < bvernoux> of course usb is more sw than hw

2014-12-08T01:05:59 < bvernoux> but using an fpga as softcore is a bad idea ;)
2014-12-08T01:06:11 < bvernoux> MCU are better for that task and less expensive
2014-12-08T01:06:24 < bvernoux> except if you need special glue logic in addition ...
2014-12-08T01:08:07 < zyp> well, sure
2014-12-08T01:09:07 < zyp> I only said that if you're for some reason doing usb on an fpga in the first place, then you probably want a softcpu to handle the upper layers

2014-12-08T05:26:51 < upgrdman> nice portrait. "here's me, bananas for scale"
2014-12-08T05:31:25 < brabo> has anyone have an opinion on these red pitaya's?
2014-12-08T05:32:00 < brabo> they seem awesome, but i am just a beginner in electronics.. adn they are costly enough to regret a bad buy :p
2014-12-08T05:32:52 < upgrdman> whats a pitaya
2014-12-08T05:33:02 < brabo> http://redpitaya.com/
2014-12-08T05:33:20 < brabo> it is a board with a lot of measurement options and stuff
2014-12-08T05:33:29 < englishman> another usb scope cool
2014-12-08T05:33:30 < upgrdman> looks kinda like an alternative to my $100 anal disco
2014-12-08T05:33:56 < englishman> this? http://www.digilentinc.com/Products/Detail.cfm?NavPath=2,842,1018&Prod=ANALOG-DISCOVERY
2014-12-08T05:33:57 < upgrdman> brabo: i have this and love it   http://www.digilentinc.com/Products/Detail.cfm?NavPath=2,842,1018&Prod=ANALOG-DISCOVERY&CFID=6924955&CFTOKEN=db35fa7dadfb130c-8F3CE6EF-5056-0201-02AF5850B09ADF00
2014-12-08T05:34:01 < englishman> how is it better
2014-12-08T05:34:42 < upgrdman> how is the red pitaya better?
2014-12-08T05:34:51 < upgrdman> the anal disco is much cheaper
2014-12-08T05:34:51 < englishman> yea
2014-12-08T05:35:01 < brabo> idk, hence my question
2014-12-08T05:35:01 < upgrdman> and well, probably better in many respects
2014-12-08T05:35:33 < brabo> i am new to electronics, but would like to have something that is good, and i see alot mentions of this red ptiaya atm
2014-12-08T05:35:36 < upgrdman> where are the RP specs
2014-12-08T05:36:45 < upgrdman> hmm the RP does seem to have some nicer qualities, but damn... that is priced way more than i would pay for it
2014-12-08T05:36:51 < englishman> cool its all done thru a web interface
2014-12-08T05:37:08 < Getty> yeah well, lets ask different: if you would have the money, is it at least worth the investment?
2014-12-08T05:37:40 < Getty> i think some dollar over price is fair, for being so community open, i admire that
2014-12-08T05:38:48 < upgrdman> is there a case for it?
2014-12-08T05:38:55 < upgrdman> seems like most open project neglect that.
2014-12-08T05:40:09 < upgrdman> and why the fuck is there no spec sheet
2014-12-08T05:43:30 < Getty> i just feel extremly motivated by the fact that the trustworthy (trust-depending) electronic dealers are "pushing" it massivly
2014-12-08T05:43:58 < Getty> thats like such a weightful motivation, but i must also admit, i already felt for the "power" of the raspberry... i might should rearrange my concepts ;)
2014-12-08T05:44:35 < Getty> what is for sure relevant for us is the ability to "get in" todo with the device as we please and not being stocked to the applicatoins they use, at least thats a dream where we like to invest
2014-12-08T05:45:01 < Getty> but if the stuff is really totally not worth it, then it might be just stupid to "nitpick" on that
2014-12-08T05:47:26 < upgrdman> so the RP is "open" right? where the schematic and board layout?
2014-12-08T05:47:38 < upgrdman> i see code in clithub, but that's it
2014-12-08T05:47:51 < Getty> i didnt checked up for the details yet if that all is true as the vision is, but that was the point why we came in here and dropped the question bomb
2014-12-08T05:48:10 < Getty> clithub hehe.... then i must be a clit commander ;)
2014-12-08T05:48:42 < englishman> i dont think anyone ever said the rpi would be open
2014-12-08T05:48:54 < englishman> they cant even release broadcom datasheetz
2014-12-08T05:49:00 < englishman> or something
2014-12-08T05:49:08 < Getty> wait wait
2014-12-08T05:49:13 < Getty> we talked about Red Pitaya
2014-12-08T05:49:28 < Getty> i just mentioned RPi in the context of buying wrong products ;)
2014-12-08T05:49:28 < englishman> oh he said RP lol my mistake
2014-12-08T05:49:33 < Getty> yeah
2014-12-08T05:49:49 < upgrdman> i meant rp as in red pitaya
2014-12-08T05:49:54 < Getty> but seriously, that we hvae the code of the device itself, is something unique for messurement devices, or?
2014-12-08T05:50:10 < upgrdman> and wtf is a pitaya? is that a word is some language?
2014-12-08T05:50:14 < Getty> hehehehhe
2014-12-08T05:50:29 < GargantuaSauce> dragon fruit
2014-12-08T05:50:35 < upgrdman> maybe it means "red anus" is some language
2014-12-08T05:50:40 < GargantuaSauce> tastes like ass but looks cool
2014-12-08T05:50:41 < upgrdman> GargantuaSauce: really?
2014-12-08T05:50:45 < GargantuaSauce> ya
2014-12-08T05:50:46 < upgrdman> cool
2014-12-08T05:51:21 < Getty> now we are more wise
2014-12-08T05:51:32 < Getty> we found out how the product name tastes ;)
2014-12-08T05:51:36 < Getty> its... progress
2014-12-08T05:52:53 < upgrdman> any verilogers here? "input  [16-1: 2] adc_dat_a_i" 16-1 just means 15 right, or is that some special syntax?
2014-12-08T06:02:41 < upgrdman> i have a vinyl cutter and a MBP. tempted to do this:  http://imgur.com/gwV3SlD
2014-12-08T06:06:14 < GargantuaSauce> should be goatse instead
2014-12-08T06:09:45 < upgrdman> i dont think i could use my laptop on campus if i went the goatse route.
2014-12-08T06:10:03 < upgrdman> well i could, but would get more "wtf" than "lol"s
2014-12-08T06:11:16 < GargantuaSauce> and this is a problem?
2014-12-08T06:12:01 < madist> what is this: http://i.imgur.com/dYuv8nG.jpg ? (showed up as "related" to upgrdman's picture)
2014-12-08T06:12:12 < upgrdman> lol
2014-12-08T06:12:17 < upgrdman> it wasnt my pic
2014-12-08T06:12:24 < upgrdman> and that's another pic from r/wtf.

2014-12-08T06:14:19 < madist> the comments on that thread are worse than the picture

2014-12-08T06:19:46 < madist> resistor ladder ?
2014-12-08T06:19:46 < upgrdman> ya, just for fun, not because i need an awesome adc
2014-12-08T06:19:59 < madist> the 0.1% resistors alone will cost more than your FPGA
2014-12-08T06:20:09 < upgrdman> madist: no. using LVDS input as a delta-sigma stage. one sec.
2014-12-08T06:20:50 < upgrdman> R2COM: it should be a simple, fun learning experience for me. we can't all be pro trolls :)

2014-12-08T08:14:26 < upgrdman> reading reviews of a fan on amazon...
2014-12-08T08:14:28 < upgrdman> "how cold is the air it blows out?
2014-12-08T08:14:29 < upgrdman> A:  Exactly the same temperature as the air that it sucks in..."

2014-12-08T08:16:59 < emeb_mac> outgoing air might be a bit warmer actually
2014-12-08T08:17:02 < upgrdman> was that idiot dropped on his head
2014-12-08T08:17:22 < GargantuaSauce> yes it would definitely be slightly warmer
2014-12-08T08:17:35 < GargantuaSauce> unless it's a magic 100% efficient motor
2014-12-08T08:17:36 < upgrdman> emeb_mac: no shit. my 2yr old column fan's motor gets hot: http://www.farrellf.com/temp/thermal_image_fan.jpg
2014-12-08T08:18:29 < emeb_mac> even if the motor was 100% and didn't get hot the friction of air against fan blade would warm it.

2014-12-09T03:24:04 < emeb> eclipse users don't have a sec - spending too much time tying to figure out their perspectives.
2014-12-09T03:29:58 < gxti> chip or module wouldn't make a difference, you still have to get the finished product certified in order to sell it. but maybe it helps smooth that process.
2014-12-09T03:30:38 < emeb> makes sense
2014-12-09T03:31:10 < ds2> *yawn*
2014-12-09T03:34:13 < emeb> yo ds2 - long time.
2014-12-09T03:36:02 < ds2> hey emeb...
2014-12-09T03:36:58 < emeb> ds2: things have been really slow here project-wise.
2014-12-09T03:37:25 < emeb> a couple things on extreme back burner but nothing in immediate operation.
2014-12-09T03:37:43 < ds2> emeb: been buried in other stuff myself
2014-12-09T03:37:56 < emeb> got that beaglebone ads-b board prototype built but not really happy with the performance so I didn't want to drag you into it.
2014-12-09T03:38:07 < ds2> think you mentioned that before
2014-12-09T03:38:20 < emeb> prolly - it's been months since I messed with it.
2014-12-09T03:38:45 < ds2> RF stuff never seems to go according to plan
2014-12-09T03:39:19 < emeb> true. this one seems to be very sensitive to radiated crud from the BBB
2014-12-09T03:39:53 < ds2> didn't think the BBB is that dirty. it is apparently clean enough for certs
2014-12-09T03:40:13 < emeb> not surprising considering the architecture - uses a broadband logamp that picks up everything from 10MHz to 4GHz.
2014-12-09T03:40:55 < ds2> why not put a band pass in front of it?
2014-12-09T03:41:21 < emeb> ds2: there are two narrowband BPF SAWs in front of it, but the signal still goes to a broadband detector
2014-12-09T03:41:58 < emeb> and since it's a logamp with like 90dB of dynamic range it picks up stuff that leaks in after the filters.
2014-12-09T03:42:21 < ds2> weren't you going to try the cans?
2014-12-09T03:42:28 < emeb> Cans are on
2014-12-09T03:42:39 < ds2> Oh
2014-12-09T03:42:49 < ds2> time to wheel out the gaskets and other exotics?
2014-12-09T03:42:51 < emeb> Going to try locating the RF board a little ways from the BBB
2014-12-09T03:43:05 < emeb> communication is SPI and I2C so only a few wires needed.
2014-12-09T03:43:36 < emeb> but ultimately I've got an STM32F42x board I'm doing with BBB formfactor that can also drive it.
2014-12-09T03:43:46 < emeb> will see if the MCU is quieter than the BBB
2014-12-09T03:44:01 < ds2> what about put the RF board inside one of those metal enclosures and provide an optically isolted output for the SPI/I2C?
2014-12-09T03:44:17 < ds2> (using a battery inside the enclosure)
2014-12-09T03:44:20 < emeb> ds2: there's an idea - seems like overkill but might help.
2014-12-09T03:44:25 < emeb> last resort.
2014-12-09T03:44:29 < ds2> it'd be for debugging
2014-12-09T03:45:00 < ds2> from the tear down of things like spec an, it can probally be pared down a lot from that
2014-12-09T03:45:26 < emeb> yep
2014-12-09T03:45:45 < ds2> on a different thing - do you think a SPI bus at 25MHz running over wires about 6-8 inches away will just work w/o any special treatment?
2014-12-09T03:46:07 < emeb> 6-8 in should be fine.
2014-12-09T03:46:49 < ds2> no series resistors, etc?
2014-12-09T03:47:06 < emeb> that's < 1ns prop delay so it shouldn't be too sensitive.
2014-12-09T03:47:21 < emeb> might radiate some noise, but otherwise not an issue.
2014-12-09T03:47:39 < emeb> run a gnd wire along with it, bundled close and you should be OK.
2014-12-09T03:47:43 < ds2> was more worried about reflections messing up the clock
2014-12-09T03:48:07 < ds2> would it hurt if I wrap the entire wire bundle in grounded copper foil (one end only)?
2014-12-09T03:48:07 < upgrdman> my latest innovation:  https://www.youtube.com/watch?v=mh_3MXEvuL8&list=UU_vO52hFzjMd2bPQA5AaHhg
2014-12-09T03:48:41 < emeb> 25MHz is 40ns, so round trip prop delay on the wires is about 1/100th of the total cycle.
2014-12-09T03:49:09 < emeb> You might get some funky edges, but that's all - if the setup/hold time is good then data integrity should be fine.
2014-12-09T03:49:39 < ds2> 'k
2014-12-09T03:49:41 < emeb> ds2: copper shield is not a bad idea
2014-12-09T03:49:58 < emeb> make sure that there's a good gnd connection on both ends though.
2014-12-09T03:50:13 < ds2> BOTH?
2014-12-09T03:50:13 < emeb> needs a return path for the switching currents.
2014-12-09T03:50:30 < emeb> not the shield but a wire along with the rest.
2014-12-09T03:50:32 < ds2> thought the rule was ground only one end of the shield
2014-12-09T03:50:34 < ds2> oh
2014-12-09T03:51:34 < emeb> the two ends do have common power / gnd, no?
2014-12-09T03:52:00 < ds2> ground, yes.
2014-12-09T03:52:03 < ds2> power maybe
2014-12-09T03:52:11 < emeb> ok - at least gnd.
2014-12-09T03:52:25 < ds2> one side is 3.0. Otherside is 3.3V. haven't decided on the shifting or powering yet
2014-12-09T03:52:28 < varesa> I guess I'll go back to keil then, though I hate the editor
2014-12-09T03:52:32 < ds2> trying to hook up a thermal camera :D
2014-12-09T03:52:38 < emeb> aha!
2014-12-09T03:52:58 < emeb> one of those slow SPI ones from that outfit in Hillboro OR?
2014-12-09T03:53:32 < ds2> no. it is a complete module for something like 80x60 res.
2014-12-09T03:53:44 < ds2> Hillboro?
2014-12-09T03:53:48 < emeb> upgrdman: what's going on there - simple counter in a Lattice FPGA?
2014-12-09T03:53:56 < emeb> ds2: Hillsboro?
2014-12-09T03:54:03 < upgrdman> ya. my first test.
2014-12-09T03:54:04 < ds2> donno of any sources in OR
2014-12-09T03:54:23 < emeb> ds2: what's the mfg name?
2014-12-09T03:54:36 < emeb> I forgot the name of the one I saw earlier...
2014-12-09T03:54:51 < ds2> emeb: FLIR
2014-12-09T03:55:00 < emeb> yeah - that's it.
2014-12-09T03:55:07 < ds2> upgrdman: what kind of transistors in in the induction heater?
2014-12-09T03:55:12 < ds2> they are located up there?!
2014-12-09T03:55:22 < upgrdman> "there"?
2014-12-09T03:55:28 < ds2> sorry
2014-12-09T03:55:37 < ds2> emeb: they are located in Hillsboro OR?
2014-12-09T03:55:47 < upgrdman> ds2: i dont recall exact number. some shitty FETs that are most likely out of production. >15 yr old stock
2014-12-09T03:56:10 < emeb> ds2: guess not - FLIR is in NC
2014-12-09T03:56:31 < upgrdman> iirc they're roughly 60v 40a 8mOhm
2014-12-09T03:56:43 < ds2> upgrdman: nice work on the heater
2014-12-09T03:56:46 < upgrdman> thanks
2014-12-09T03:56:53 < ds2> oh... beefy stuff
2014-12-09T03:57:22 < emeb> ds2: oh wait - FLIR corp is in *Wilsonville* OR, not Hillsboro. Only about 20mi apart. :)
2014-12-09T03:57:35 < upgrdman> ds2: bought some of these for my newer projects:  http://www.ti.com/lit/ds/symlink/csd19536kcs.pdf
2014-12-09T03:57:37 < emeb> You working with one of their Lepton modules?
2014-12-09T03:57:56 < ds2> emeb: yeah
2014-12-09T03:58:14 < emeb> ds2: mranostay over on the BBB chl did one of those too.
2014-12-09T03:58:29 < ds2> Ohhhh I see
2014-12-09T03:58:35 < emeb> I think he's got a kernel driver for BBB already.
2014-12-09T03:58:57 < ds2> upgrdman: that is a beefy fet
2014-12-09T03:59:08 < ds2> emeb: oh nice... but it is probally for DT
2014-12-09T03:59:10 < upgrdman> :)
2014-12-09T03:59:18 < emeb> ds2: ya probably
2014-12-09T03:59:23 < ds2> going to get my image processing code working before I do the HW
2014-12-09T03:59:37 < emeb> kewl
2014-12-09T03:59:51 < emeb> upgrdman: 100V @ 150A - honking!
2014-12-09T03:59:56 < ds2> it is going into a head mounted unit
2014-12-09T04:00:35 < emeb> ds2: those FLIR modules are pretty cool - too bad that they're statutorily limited in resolution / framerate.
2014-12-09T04:00:41 < upgrdman> ya no shit :) i picked them as a sort of "fuck it. these will do anything i need" ... highish voltage, high current, FAST, low Rds-on, etc.
2014-12-09T04:00:50 < emeb> I guess Uncle Sam doesn't want the terrists to have good night vision.
2014-12-09T04:00:59 < ds2> emeb: not really in resolution. there is another USB one that does like 320x200ish
2014-12-09T04:01:18 < ds2> upgrdman: how are you powering it? straight off the mains?
2014-12-09T04:01:27 < upgrdman> no

2014-12-09T04:01:53 < ds2> emeb: problem is most folks just want the images. I want to do something with the data
2014-12-09T04:02:08 < ds2> 32V@30A will melt aluminum?!
2014-12-09T04:02:15 < ds2> hmmm a desktop caster
2014-12-09T04:02:25 < emeb> that'd be handy
2014-12-09T04:03:12 < emeb> combine with a centrifuge and go nuts!
2014-12-09T04:03:30 < ds2> maybe not... melted aluminum is like 1200+
2014-12-09T04:03:44 < upgrdman> ds2: easily.
2014-12-09T04:03:51 < upgrdman> i was only at 14V 28A
2014-12-09T04:04:01 < upgrdman> of course, i cant melt big ass ingots...
2014-12-09T04:04:14 < ds2> upgrdman: can you melt a thumb sized crucible of alum?
2014-12-09T04:04:24 < upgrdman> but im doing this on a shitty ikea desk, so i probably shouldn't setup a foundry on it
2014-12-09T04:04:31 < ds2> hahaha
2014-12-09T04:04:32 < upgrdman> maybe with a lot of time
2014-12-09T04:04:36 < emeb> :)
2014-12-09T04:04:47 < upgrdman> i was using these: http://pdf.datasheetcatalog.com/datasheet/toshiba/2986.pdf
2014-12-09T04:04:52 < ds2> personal desktop foundries
2014-12-09T04:05:09 < upgrdman> the humble beginnings of my induction heater: http://www.farrellf.com/temp/induction_heater_revA.jpg
2014-12-09T04:05:38 < emeb> wonder if you could use molten Al instead of plastic in a 3D printer. :)
2014-12-09T04:06:39 < emeb> I'm guessing Al doesn't have enough viscosity for that, and the oxide would prevent good adhesion of layers...
2014-12-09T04:06:46 < ds2> what frequency is it running at?
2014-12-09T04:07:12 < ds2> emeb: run it in an inert enviroment. maybe a 55 gallon drop with CO2?
2014-12-09T04:07:43 < upgrdman> ds2: 60ish kHz
2014-12-09T04:08:10 < varesa> upgrdman: next fpga project for you :) https://www.youtube.com/watch?v=r6Gq1VcuaCo
2014-12-09T04:08:18 < ds2> sinewaves?
2014-12-09T04:08:38 < upgrdman> ds2: i also have to watercool the capacitors. they get hot :)  http://www.farrellf.com/temp/burned_mlcc_capacitor_taiyo_yuden_UMK325C7106MM-T_50V_10uF.jpg
2014-12-09T04:09:32 < upgrdman> varesa: nice. why unlisted?
2014-12-09T04:09:45 < upgrdman> the first project i had to do for an fpga class was BCD -> 7seg
2014-12-09T04:09:57 < upgrdman> in schematic capture!
2014-12-09T04:09:59 < varesa> just the defaults, took the video few minutes ago on my phone
2014-12-09T04:10:11 < upgrdman> prof hated HDL
2014-12-09T04:10:38 < ds2> MLCCs get hot? wow
2014-12-09T04:10:45 < ds2> wonder if there is a better dielectric
2014-12-09T04:11:06 < varesa> that was basically my first fpga project, counter -> split to bcd -> bcd to 7 seg -> multiplex
2014-12-09T04:12:42 < upgrdman> ds2: i bought some super-low-esr mlcc's after that. rated for SMPSs. they're much better but still get hot when they get 400W going through them
2014-12-09T04:13:42 < upgrdman> varesa: i should get a bigger quad like you. mine is small: http://www.farrellf.com/temp/quadcopter.jpg
2014-12-09T04:15:29 < varesa> upgrdman: here is some gps testing: https://www.youtube.com/watch?v=gnARuavayzE :)
2014-12-09T04:16:44 < upgrdman> flew away or intentional?
2014-12-09T04:16:52 < upgrdman> (waypoints?)
2014-12-09T04:16:58 < varesa> intentional, waypoints
2014-12-09T04:17:02 < ds2> upgrdman: sounds like you need to submerge the entire thing in oil
2014-12-09T04:17:23 < upgrdman> ds2: could. i have the caps and FET heatsinks in a water bath
2014-12-09T04:17:33 < upgrdman> isnt water more thermally conductive than most oils?
2014-12-09T04:19:26 < ds2> water is also electrically conductive there is any impurities
2014-12-09T04:19:30 < emeb> that
2014-12-09T04:19:53 < upgrdman> ya
2014-12-09T04:20:11 < upgrdman> but i didnt notice any problems (no signif bubbling)
2014-12-09T04:31:02  * emeb has big fun driving WS2812 RGB LEDs from an STM32F100
2014-12-09T04:35:19 < ds2> emeb: how many of them have you driven at once?
2014-12-09T04:35:40 < emeb> ds2: the board I'm doing now just has 4 - no big thing.
2014-12-09T04:35:51 < emeb> I've got an adafruit board with 40 in a 5x8 grid tho
2014-12-09T04:36:58 < upgrdman> what do you plan to do with the LEDs
2014-12-09T04:37:38 < emeb> upgrdman: this is a display board that goes along with an analog shift register module for electronic music synthesis.
2014-12-09T04:37:56 < emeb> uses LED colors to indicate voltages in the shift register...

2014-12-09T07:31:02 < GargantuaSauce> just depends on what you want out of the board i guess
2014-12-09T07:31:16 < upgrdman> of course not
2014-12-09T07:31:36 < upgrdman> im just learning about fpgas. figured it would be good to try different stuff

2014-12-09T08:06:12 < emeb_mac> you said it has a tracking gen on it right?
2014-12-09T08:06:20 < emeb_mac> pretty nice if so.
2014-12-09T08:06:54 < emeb_mac> if you can do S11 and S21 then it's almost a network analyzer
2014-12-09T08:07:03 < emeb_mac> even if you can't do them simultaneously
2014-12-09T08:09:16 < emeb_mac> that's a pretty nice deal
2014-12-09T08:09:38 < emeb_mac> It's probably just a directional coupler

2014-12-09T08:10:01 < emeb_mac> you could fake one up yourself for less $$ if you wanted.
2014-12-09T08:10:15 < emeb_mac> just buy a generic coupler somewhere...

2014-12-09T08:49:04 < emeb_mac> R2COM: PMODs are all different because they're intended to hook to FPGAs
2014-12-09T08:49:13 < emeb_mac> FPGAs can assign pins as needed.
2014-12-09T08:53:46 < upgrdman> the digilent board use some high speed connectors, but only for shitloads of pins
2014-12-09T08:53:55 < upgrdman> like a hirose fx2 with 100 pins
2014-12-09T08:54:19 < upgrdman> they use 0.1" for pmods so people can nig rig their own stuff easily.
2014-12-09T09:00:04 < emeb_mac> yes that
2014-12-09T09:01:02 < emeb_mac> xilinx & altera also have "mezzanine" connectors for really fast stuff

2014-12-09T16:04:06 < dirty_d> yea, it goes to the usb user data -
2014-12-09T16:04:13 < dirty_d> but its not connected to anything
2014-12-09T16:04:57 < dirty_d> just goest to the usb connector through a 22ohm resistor

2014-12-09T16:09:16 < Laurenceb_> no 22ohm required iirc

2014-12-09T16:13:29 < dirty_d> i think it must be my code
2014-12-09T16:13:42 < dirty_d> it did the same thing on GPIOE

2014-12-09T22:25:43 < kakeman> one design has ref clock from oscillator directly
2014-12-09T22:26:18 < kakeman> but there is 25mhz_out pin in phy that says reference clock
2014-12-09T22:26:43 < scrts> I've used Micrel, but it's more or less the same I think
2014-12-09T22:26:45 < scrts> this is 10/100?
2014-12-09T22:27:42 -!- enomado [~enomado@195.78.246.136] has quit [Remote host closed the connection]
2014-12-09T22:27:51 < scrts> oh yes, it is
2014-12-09T22:27:52 < kakeman> I just read about rmii so it lists pin used in this mode
2014-12-09T22:28:02 < kakeman> X1 is pin used
2014-12-09T22:28:17 < scrts> hm, I used MII with it
2014-12-09T22:28:27 < kakeman> sorry mates I don't read pdf throughly
2014-12-09T22:29:03 < scrts> ref clk in rmii mode should be the one you need
2014-12-09T22:30:53 < PaulFertser> kakeman: 25mhz_out is likely just an aux clock based on RMII input clock, it might be out of phase with the RMII clock, you likely do not need it for anything.
2014-12-09T22:31:39 < kakeman> that's what I thought
2014-12-09T22:33:04 < scrts> but input clock is the oscillator?
2014-12-09T22:33:06 < PaulFertser> kakeman: you can generate 25MHz with stm32 without any additional oscillators, using internal PLLs and MCO.
2014-12-09T22:33:26 < scrts> he need 50MHz I think for RMII
2014-12-09T22:33:37 < kakeman> yes

2014-12-09T22:33:49 < scrts> but anyway, you must check if the stability and jitter of PLL is in the required range
2014-12-09T22:33:50 < kakeman> oscillator 50Mhz
2014-12-09T22:33:55 < scrts> otherwise you could get errors
2014-12-09T22:34:12 < kakeman> it is not for ethernet I think?
2014-12-09T22:34:13 < scrts> e.g. for Gbit you can't use PLL output
2014-12-09T22:34:22 < PaulFertser> Right, 50MHz

2014-12-10T01:19:26 < Steffanx> swo is useable kakeman, which is a subset of the full trace port stuff
2014-12-10T01:20:39 < kakeman> is using those trace pins like legacy stuff compared to swo?

2014-12-10T08:43:40 < emeb_mac> ya
2014-12-10T08:43:40 < ds2> that's where the 6MHz part comes from
2014-12-10T08:43:56 < ds2> all I need it to do is sum a DC voltage to it

2014-12-10T08:46:44 < dongs> ds2: run your input video through that first
2014-12-10T08:46:49 < dongs> to remove any possible ac bias
2014-12-10T08:46:58 < dongs> then just pull it to ntsc_white / ntsc_black
2014-12-10T08:47:17 < ds2> hmmm? that won't get me transparency
2014-12-10T08:47:22 < dongs> yes it will
2014-12-10T08:47:33 < dongs> oh, i see wat you mean
2014-12-10T08:47:37 < ds2> what do you mean by "pull it"?

2014-12-10T08:48:13 < ds2> that won't do transparency either
2014-12-10T08:48:27 < ds2> only way to do it is to sum a DC voltage to alter the luma
2014-12-10T08:48:50 < emeb_mac> ds2: diode drop

2014-12-10T08:50:41 < dongs> yep
2014-12-10T08:50:54 < ds2> emeb_mac: not much granularity given that NTSC video is about 0.3V to 1.0 (useful range)
2014-12-10T08:51:20 < emeb_mac> yeah. use a schottky
2014-12-10T08:51:31 < ds2> actually that won't work at all
2014-12-10T08:52:00 < ds2> cuz for a dim video signal where the active region is ~0.3-0.6V, this would screw up sync
2014-12-10T08:52:43 < emeb_mac> for brighter you can use a mirror structure with more diodes on the other side
2014-12-10T08:53:23 < ds2> mirror? it seems like I am not following you... I thought you were suggesting running the video through a schottky to subtract ~0.3V from it
2014-12-10T08:54:10 < emeb_mac> or you can have a diode to a pullup to give a 0.3V rise.
2014-12-10T08:54:45 < zyp> dongs, well, I'm certainly not opposed to that price, so just mail me the invoice to pay when you've got one
2014-12-10T08:54:51 < dongs> right lol
2014-12-10T08:55:01 < ds2> hmmmm think I need to dig up my old EE text

2014-12-10T09:32:33 < jpa-> fix your own broken one
2014-12-10T09:32:57 < dongs> madist: swap spi flash from your current dead pcb, put new board in, read data off drive
2014-12-10T09:33:16 < madist> dongs: does that actually work ? like you did it yourself not heard someone claim they did it ?
2014-12-10T09:33:31 < dongs> it works
2014-12-10T09:33:36 < madist> afaik there is data on the platters in addition to the spi due to which it shouldn't work.
2014-12-10T09:33:45 < dongs> ...
2014-12-10T09:33:48 < dongs> yes, you keep your platters
2014-12-10T09:33:50 < dongs> and keep SPI
2014-12-10T09:33:55 < dongs> and replace driver board only.
2014-12-10T09:34:06 < dongs> all device-unique shit is in SPI
2014-12-10T09:34:11 < ReadError> most drive failures are the board
2014-12-10T09:34:17 < jpa-> lol sherlock
2014-12-10T09:34:22 < madist> I meant calibration and config data on the platters ;)
2014-12-10T09:34:44 < jpa-> you keep the hardware, you keep the platters, why wouldn't the old calibration data work?
2014-12-10T09:34:44 < dongs> r u dum, you have a drive with dead controller board
2014-12-10T09:34:47 < dongs> but working platters/motors
2014-12-10T09:35:06 < dongs> you replace board, keeping spi flash from old dead controlelr board.
2014-12-10T09:35:11 < madist> jpa-: no idea. maybe some checksums or something ?
2014-12-10T09:35:27 < jpa-> well it does work, as long as you get the model & version correct
2014-12-10T09:35:33 < madist> because I know someone who tried it and it didn't work. That's why I'm asking dongs if he actually did it himself or just heard the story on the grapevine.
2014-12-10T09:35:47 < dongs> madist: what did they "do"
2014-12-10T09:35:48 < PaulFertser> madist: actually, many people can swap boards the way dongs describes, but they also can recalibrate when needed, swap platters etc.
2014-12-10T09:36:10 < PaulFertser> madist: I know local professionals doing that for data recovery routinely.
2014-12-10T09:36:17 < madist> dongs: 2 identical drives, one dead. swapped the winbond chip on the boards and then swapped the boards.
2014-12-10T09:36:22 < jpa-> madist: yeah, it is hit-or-miss; sometimes the fault is not on the board, sometimes there are subtle version differences etc.
2014-12-10T09:37:55 < PaulFertser> One guy told me he swaps high-density platters in a bathroom (where the humidity level helps combat the dust) and it works just fine to recover the data.

2014-12-10T12:15:51 < dongs> USB-ARM-JTAG Or so
2014-12-10T12:15:58 < dongs> what version of openocd does he need to get swd on it
2014-12-10T12:16:08 < dongs> he updated to latest hotdogredhat and theres still nothing
2014-12-10T12:16:29 < jpa-> which article?
2014-12-10T12:16:44 < PaulFertser> dongs: he needs to grab from git as it wasn't part of 0.8.0, so I'd recommend git HEAD. He'd also need an SWD adapter or use the resistor hack.
2014-12-10T12:17:11 < dongs> PaulFertser: he linked to some swd adapter thing, it had a shitton of components.
2014-12-10T12:17:14 < dongs> that one?
2014-12-10T12:17:54 < dongs> he's poor and opensource, so he'll probly choose resistor hack
2014-12-10T12:17:56 < dongs> got a link?
2014-12-10T12:17:58 < PaulFertser> dongs: probably. Does he have it already? if not, I'd recommend the resistor hack.
2014-12-10T12:18:05 < dongs> no, he dosnt

2014-12-10T12:19:27 < dongs> OK, retweeted
2014-12-10T12:19:42 < dongs> duno why he insists on opensoresing, cuz he even has a 401 nucelo and shit
2014-12-10T12:19:50 < dongs> which has at least proper closed-source debug probe
2014-12-10T12:20:21 < PaulFertser> You can't use stlink to unlock a Tiva C or a Kinetis part.
2014-12-10T12:21:42 < PaulFertser> Also, you can't use stlink for random jtag work (be it a chained microcontroller config or some CPLD or what's not).
2014-12-10T12:22:43 < Taxman> hi
2014-12-10T12:23:42 < Taxman> PaulFertser: Are you the one that told me that the FT2232D can do SWD the same speed as jtag?
2014-12-10T12:23:51 < PaulFertser> Taxman: probably
2014-12-10T12:24:24 < Taxman> ok
2014-12-10T12:24:48 < Taxman> the problem are this drivers at the output that can't do bidirectional hehe
2014-12-10T12:26:45 < PaulFertser> Taxman: yes, kinda, but works reasonably nice with a resistor hack.
2014-12-10T12:27:20 < Taxman> ahh
2014-12-10T12:27:25 < Taxman> so only a resistor hack?
2014-12-10T12:27:58 < Taxman> i can't see there a signal for controlling the direction of a bidirectional driver
2014-12-10T12:28:29 < PaulFertser> Taxman: if you buy an SWD adapter, you should better use it instead of the hack.
2014-12-10T12:28:52 < Taxman> :)
2014-12-10T12:29:22 < Taxman> i thought about if there is a way to get adapters like turtelizer 2 be able to do SWD

2014-12-10T12:39:47 < PaulFertser> And I agree, probably jlink clone is now a better bargain by all means.
2014-12-10T12:40:08 < PaulFertser> As it costs just about 10$.
2014-12-10T12:40:19 < dongs> or a legit jlink-edu

2014-12-10T16:48:08 < jadew> two habits of mine paid out today
2014-12-10T16:48:21 < jadew> 1) wearing protective glasses while soldering.
2014-12-10T16:49:15 < jadew> 2) buying more than I need - fried OCXO in my external freq. standard
2014-12-10T16:52:08 < zyp> protective glasses while soldering? people do that?
2014-12-10T16:52:56 < jadew> yeah, most people think it's silly, but I had stuff flying from the soldering point too many times to risk it
2014-12-10T16:53:10 < jadew> both solder and flux
2014-12-10T16:53:22 < zyp> I've never even thought about it
2014-12-10T16:55:32 < Steffanx> i "trust" my normal glasses to protect my eyes while solderen

2014-12-10T16:56:37 < jadew> the biggest danger is when you're soldering/desoldering wires
2014-12-10T16:56:56 < jadew> they can throw solder anywhere

2014-12-10T21:59:30 < zyp> according to amlogic, the S805 doesn't have a gigabit mac
2014-12-10T22:01:38 < emeb> heh - minor detail.
2014-12-10T22:01:52 < emeb> maybe they figured it's good enough to put on a gigE phy

2014-12-10T22:03:22 < zyp> http://www.amlogic.com/product05.htm <- ok, I was looking here
2014-12-10T22:03:55 < zyp> you'd think that amlogic.com has correct specs for their chips :p
2014-12-10T22:04:50 < emeb> "a foolish consistency is the hobgoblin of little minds"
2014-12-10T22:06:06 < Steffanx> it depends on which S805 you are looking for on their website zyp
2014-12-10T22:06:19 < Steffanx> "IP/OTT STB SoC" shows the one WITH 1000M
2014-12-10T22:06:37 < zyp> what, are there more than one S805 too?
2014-12-10T22:07:31 < Steffanx> Probably the same but..
2014-12-10T22:08:58 < emeb> too bad no SATA - could make a little NAS with it otherwise.

2014-12-11T03:32:50 < dongs> With ESS patented 32-bit Hyperstream. DAC architecture and Time Domain Jitter Eliminator, the SABRE32 Reference Stereo DAC delivers an unprecedented DNR of up to 135dB and THD+N of -120dB, the industry.s highest performance level that will satisfy the most demanding audio enthusiasts.
2014-12-11T03:33:27 < GargantuaSauce> 32 bit samples??
2014-12-11T03:33:36 < GargantuaSauce> so you can have like 18 bits of noise?
2014-12-11T03:33:40 < dongs> yes
2014-12-11T03:33:46 < GargantuaSauce> awesome
2014-12-11T03:34:07 < GargantuaSauce> i bet the soundstage is really broad.
2014-12-11T03:34:35 < dongs> Listening through a pair of Beyerdynamic DT 770 Pro headphones, Neil Young's Heart of Gold (yep, there was plenty of Neil Young on board), sounded spacious and detailed, with Young's voice crackling with emotion and a real sense of texture to every strum of the guitar.
2014-12-11T03:34:40 < dongs> The trademark harmonica rasped loud and clear without sounding harsh, the PonoPlayer maintaining composure even at high volume.
2014-12-11T03:34:44 < dongs> Switching to something more up-tempo - and produced within an inch of its life - in the form of Daft Punk's Random Access Memories, the PonoPlayer had no problem keeping time, sounding punchy and powerful with solid bass notes.
2014-12-11T03:37:09 < englishman> mcdonalds uses the same language to sell hamburgers
2014-12-11T03:37:58 < dongs> do tehy
2014-12-11T03:38:09 < dongs> do hamburgers feel punchy
2014-12-11T03:38:51 < englishman> powerful (b)ass notes
2014-12-11T03:39:01 < dongs> does 192khz even have effect on BASS
2014-12-11T03:39:10 < dongs> i thought that shit was like in low hz
2014-12-11T03:39:20 < dongs> srs question here.
2014-12-11T03:39:34 < englishman> 192khz is sample rate
2014-12-11T03:39:53 < englishman> not range
2014-12-11T03:40:53 < dongs> I just wanna know if it will help me to achieve lower lows
2014-12-11T03:40:55 < dongs> vs 44khz.
2014-12-11T03:41:40 < englishman> well 192k@32bit is higher sample rate than 44khz@8bit
2014-12-11T03:42:27 < GargantuaSauce> http://en.wikipedia.org/wiki/Nyquist%E2%80%93Shannon_sampling_theorem
2014-12-11T03:42:27 < englishman> but i think the quality of the recording studio and mixer has more of an effect on that

2014-12-11T13:07:56 < scrts_w> what service for version control is good besides github?
2014-12-11T13:08:12 < GargantuaSauce> i use bitbucket
2014-12-11T13:08:53 < GargantuaSauce> think google code is ok too
2014-12-11T13:09:00 < Thorn> bitbucket gives you private repos for free
2014-12-11T13:09:08 < Thorn> but github has suicide.txt
2014-12-11T13:09:20 < zyp> I just stick the repos on a private server
2014-12-11T13:13:07 < Thorn> the builtin bugtracker on bitbucket is pretty horrible. it's how they market jira or something
2014-12-11T13:16:24 < GargantuaSauce> havent actually used it, just jira
2014-12-11T13:16:38 < GargantuaSauce> but that is not very surprising
2014-12-11T13:17:16 < GargantuaSauce> the real question is whether "horrible" means better or worse than trac
2014-12-11T13:17:53 < GargantuaSauce> which seems to be the guiding light of all bad integrated source control + bugtrackers
2014-12-11T13:20:56 < karlp> it was better than svn+nothing which was the defacto when it came out

2014-12-11T15:51:26 < englishman> thing is with cars like that, if they are collectible and have some current value they are worth $ for the serial numbers alone
2014-12-11T15:51:53 < englishman> and sometimes, the original manufacturer will take the forms out of the warehouse and make you new parts

2014-12-11T15:54:04 < karlp> dongs: fair point :)
2014-12-11T15:54:10 < englishman> if you have the original serial number, and build a new car arond it, it's worth way more than a "replica" without an original serial number
2014-12-11T15:54:23 < Laurenceb_> $5000 amazeDAC with $5 chip ?
2014-12-11T15:54:27 < karlp> reminds me of some post I read about modding old cars,
2014-12-11T15:54:27 < dongs> did they evne have VIN back then

2014-12-11T15:54:57 < karlp> yeah, I guess you're right englishman, was reading about a bently modder, who had like, one axel left of the original, but it qualified as a bentley in some snob club,

2014-12-11T17:55:53 < decimad2> C++ is inferiour because it needs two additional chars...
2014-12-11T17:57:29 < decimad2> In the beginning they took C++, stripped it from all the fuss and called the result 'C'. And they saw it was good.
2014-12-11T17:57:39 < zyp> :)
2014-12-11T18:02:51 < decimad2> So I have a qeustion regarding the linking again... I understood why you need to link in libc before nano stuff and all, what I don't get how I never have problems linking my compilation units althouth I never cared to specify a link order
2014-12-11T18:04:17 < zyp> I think all object files are indexed before any linking happens, but not libraries

2014-12-11T18:06:16 < zyp> or rather, it's probably loading one library at a time, trying to satisfy it's dependencies, and then doing all the objects at last

2014-12-11T18:08:48 < madist> its always good to put things in the right order rather than expect the linker to resolve your shit for you.

2014-12-11T18:59:17 < karlp> this board doesn't have pullups on the rx uart line, the other board did.
2014-12-11T18:59:28 < karlp> works much more reliably now that i've just enabled the internal ones :)
2014-12-11T18:59:38 < emeb> chatter on the input?
2014-12-11T19:00:11 < karlp> seemed to be seeing it's own output, (this is rs485) even though the tx-enable/_rx-enable is meant to be mutually exclusive
2014-12-11T19:00:52 < karlp> it was making every second modbus request work, or anything that waited long enough between requests to let it inter-byte-timeout the garbage trailer stuff
2014-12-11T19:00:59 < karlp> anyway, it's nice when a single line fix is all that's needed
2014-12-11T19:01:53 < karlp> and on the bright side, I've got swo working a little better with openocd, so that's aplus

2014-12-12T17:48:34 < BrainDamage> when it's almost closed, it becomes super hard
2014-12-12T17:49:24 < karlp> what am I looking at there?
2014-12-12T17:49:32 < BrainDamage> a rocket spin system
2014-12-12T17:49:55 < BrainDamage> you make the rocket spun on it's axis prior to launch to stabilize the trajectory
2014-12-12T17:49:59 < Laurenceb_> yeah
2014-12-12T17:50:05 < Laurenceb_> it spins at ~20krpm
2014-12-12T17:50:22 < BrainDamage> i assume the plastic attachments will be melted by the exaust
2014-12-12T17:50:27 < Laurenceb_> shrug
2014-12-12T17:50:36 < Laurenceb_> probably
2014-12-12T17:50:59 < Laurenceb_> the hard bit is getting it spinning on its principle axis
2014-12-12T17:51:05 < Laurenceb_> that was a major headache

2014-12-13T00:31:01 < kakeman> guys I need to isolate ADC and DAC reference and supply pins
2014-12-13T00:31:16 < kakeman> does isolation in this case mean using ferrite beads?
2014-12-13T00:31:55 < kakeman> and maybe a low pass filter?
2014-12-13T00:32:40 < kakeman> it says to isolate both avcc and avss
2014-12-13T00:33:56 < kakeman> I would have left any negative pin tied straight to ground but
2014-12-13T00:36:21 < kakeman> analog ground should be seperate thru all the system then
2014-12-13T00:38:58 < kakeman> I see that evalution boards connect negative analog pins straight to ground and positive pins are supplied thru ferrite
2014-12-13T00:39:15 < kakeman> just how I have used to do
2014-12-13T00:42:40 < kakeman> when doing serious analog stuff it's a different story I think
2014-12-13T00:43:16 < kakeman> and external converters
2014-12-13T00:44:12 < Laurenceb__> it depends how good you want the performance to be

2014-12-13T05:40:03 < madist> during the california gold rush, the people who got rich were the store owner, the bar owners and the hookers.
2014-12-13T05:40:33 < madist> something similar probably will happen with internet startups.
2014-12-13T05:41:09 < dongs> Crowdfunding campaigns offer a great opportunity for validation if you are aiming at the mass audience. They are especially useful for physical products and innovations. You don.t have to create the product itself, just remember to present your prototype or idea well. Check Kickstarter, Indiegogo or RocketHub for great  MVP examples.

2014-12-13T07:12:41 < louloulou> Man I am going crazzy -- can anyone help me with GCC on an STM32f0?
2014-12-13T07:13:55 < louloulou> hello??
2014-12-13T07:14:13 < louloulou> Please?
2014-12-13T07:15:28 < upgrdman> q?
2014-12-13T07:16:07 < qyx_> you shouldnt ask if you can ask, just write you question
2014-12-13T07:16:07 < upgrdman> pro tip: just ask your question. if someone can/wants to help, they will.
2014-12-13T07:18:08 < louloulou> Ok - is a bear.. And stupid.. I am trying to  use GCC on a STM32F072 - and I have the simplest of stupid ass programs I have written.
2014-12-13T07:18:32 < louloulou> I have used 3 or 4 diferent linker scripts..
2014-12-13T07:18:51 < louloulou> I have used two diferent versions of GNU-ARM.
2014-12-13T07:19:02 < louloulou> I have used two diferent computers..
2014-12-13T07:19:38 < louloulou> but every time I try to compile a sprintf("Some stupid text %d",x);
2014-12-13T07:19:56 < louloulou> the linker barfs on me and says that sections overlap..
2014-12-13T07:20:14 < qyx_> which F072?
2014-12-13T07:20:19 < qyx_> which gcc?
2014-12-13T07:20:32 < louloulou> BUT - If i do a sprintf without attempting to print a var - it compiles!
2014-12-13T07:20:52 < upgrdman> where did you get your gcc? gae?
2014-12-13T07:21:01 < louloulou> STM32f072 ?? -- the one on the discovery board - 64 pin booger
2014-12-13T07:21:03 < dongs> your sprintf() syntax is wrong
2014-12-13T07:21:04 < qyx_> how much flash your f072 has?
2014-12-13T07:21:18 < qyx_> yes, besides what dongs says
2014-12-13T07:21:32 < louloulou> GCC came from ARM's web site and from a git link (tried 2 dferent vres)
2014-12-13T07:21:33 < qyx_> sprintf requires about 20-25KB of flash space
2014-12-13T07:21:44 < dongs> furashu space
2014-12-13T07:21:50 < louloulou> I got 128K - lots free
2014-12-13T07:21:58 < qyx_> ok, so thats probably not the issue
2014-12-13T07:22:11 < louloulou> The linker output map file is totally within spec
2014-12-13T07:22:24 < louloulou> I can send you the files if u want/
2014-12-13T07:22:24 < qyx_> i would recommend to begin with some known working demo
2014-12-13T07:22:31 < louloulou> I did/.
2014-12-13T07:22:43 < qyx_> you should pastebin your linker script & main()
2014-12-13T07:22:53 < qyx_> also your linker script should match you startu
2014-12-13T07:23:00 < louloulou> I just add sprintf and i can wrek the demo. I tried two diferent templates
2014-12-13T07:23:21 < louloulou> ok stand by I will pastebin it all/./.
2014-12-13T07:23:25 < qyx_> how does the line look like?
2014-12-13T07:23:30 < qyx_> k
2014-12-13T07:23:36 < dongs> are you using gcc-arm-embedded

2014-12-13T07:24:20 < dongs> "windoze" is great
2014-12-13T07:24:25 < dongs> you should also look into proper IDEs on windows
2014-12-13T07:24:31 < dongs> like crossworks or keil
2014-12-13T07:24:53 < louloulou> IDE's hide too many details :(   - but I am drowning in them now..

2014-12-13T07:50:12 < qyx_> why
2014-12-13T07:50:15 < dongs> especially considering how ST is furiosuly deprecating stdlib for everything

2014-12-13T07:57:45 < louloulou> ok - i get it - I sort of work the opposite - I want to see the entire build envronmemt -
2014-12-13T07:58:11 < dongs> I have a STM32F429I-Discovery_FW_V1.0.1\Projects\Template i presume F0 has similar.
2014-12-13T07:58:12 < louloulou> what am I missing with the make files ?
2014-12-13T07:58:50 < louloulou> what did I do stupid?
2014-12-13T07:59:09 < louloulou> dir make*.* /s
2014-12-13T07:59:11 < madist> who you calling stupid ?
2014-12-13T07:59:21 < louloulou> reveals nothing
2014-12-13T07:59:28 < louloulou> what did I do stupidly
2014-12-13T07:59:44 < louloulou> english not my first language
2014-12-13T08:00:19 < louloulou> no offense
2014-12-13T08:02:24 < louloulou> I found ld files for true studio..
2014-12-13T08:02:38 < madist> does ST do linux ?
2014-12-13T08:02:39 < louloulou> no make

2014-12-13T09:53:27 < zyp> where's the funny?
2014-12-13T09:54:28 < dongs> perhaps the bottom statistic
2014-12-13T09:54:32 < dongs> also your stm32 shit shipped
2014-12-13T09:54:33 < dongs> + max
2014-12-13T09:54:53 < zyp> cool, got a tracking number?
2014-12-13T09:55:32 < dongs> not yet, cuz its on the way to me first. pcbs are here as well as vregs and usb shit
2014-12-13T09:56:04 < zyp> ah, right, I though you meant shipped from you
2014-12-13T09:58:08 < dongs> ya sorry not yet
2014-12-13T10:03:21 < zyp> no big deal, I won't have it before christmas anyway
2014-12-13T10:04:06 < zyp> just want the tracking number so I can send somebody to pick it up for me when it arrives
2014-12-13T10:04:15 < dongs> ok, ill tweet you asap

2014-12-13T10:32:24 < upgrdman> have a GFCI outlet in my bathroom. pushed the test button to test it, and not it wont reset.
2014-12-13T10:32:31 < upgrdman> is this a common failure mode?
2014-12-13T10:39:16 < ReadError> i think theres something you can plug in to reset them too..
2014-12-13T10:39:27 < dongs> that'd be a nice trick
2014-12-13T10:40:52 < qyx_> wut, europe gfci (rcd) have normal switch on them like overcurrent protectors
2014-12-13T10:41:01 < ReadError> hmm maybe im thinking of something else

2014-12-13T10:42:41 < ReadError> upgrdman ive had them get stuck
2014-12-13T10:42:56 < ReadError> i just kept pressing both buttons and eventually it fixed itself
2014-12-13T10:43:04 < upgrdman> hmm will try :)
2014-12-13T10:43:32 < PaulFertser> upgrdman: so, it's a power outlet with integrated RCD?
2014-12-13T10:44:35 < PaulFertser> upgrdman: you can try plugging a, say, random through-hole 4.7k resistor between the phase and ground there to test it.
2014-12-13T10:44:42 < PaulFertser> The button should be doing the same actually.
2014-12-13T10:45:08 < ReadError> AC scares the shit out of me
2014-12-13T10:45:10 < PaulFertser> upgrdman: is it possible it's incorrectly connected, i.e. the phase and neutral are switched?
2014-12-13T10:45:14 < ReadError> mess up DC, waste money
2014-12-13T10:45:19 < ReadError> mess up AC, hurts
2014-12-13T10:45:35 < PaulFertser> Duh, your headphones work on AC ;)
2014-12-13T10:45:58 < ReadError> well, 120v ac..
2014-12-13T10:46:08 < ReadError> dont wanna burn down the house
2014-12-13T10:46:16 < PaulFertser> 220V here, heh
2014-12-13T10:46:48 -!- barthess [~barthess@185.6.25.6] has joined ##stm32
2014-12-13T10:47:05 < PaulFertser> BTW, less voltage obviously means more current, so you actually have more chances of burning something down I guess.
2014-12-13T10:47:56 < ReadError> I think most of the breakers will flip at 20 or 30A in my panel
2014-12-13T10:48:44 < qyx_> uh, much current
2014-12-13T10:49:13 < PaulFertser> Likely. But all new installments in Europe have mandatory RCDs which save you not only from short-circuit and overcurrent, but also from accidental flow via ground, that's what saves lives.
2014-12-13T10:50:28 < PaulFertser> And, talking about current, imagine you have a sub-par AC power cable which is using wires too thin. With 220V you'd be pumping twice less amps than with 110V, so it'll heat up way less.
2014-12-13T10:52:56 < PaulFertser> upgrdman: if you do not have a phase indicator, you can take some lamp or whatever, and connect it between the ground and either of the two contacts. If it activates the protection, it means you found the phase (and it's improperly connected), if it just lights up, it means the RCD is broken.
2014-12-13T10:54:25 < qyx_> connection between PE and N could also trip it
2014-12-13T10:54:40 < qyx_> if they are at slightly different potential what is usually the case
2014-12-13T10:54:49 < qyx_> as N carries current
2014-12-13T10:55:11 < upgrdman> PaulFertser: outlet work and tested fine for years.
2014-12-13T10:55:33 < upgrdman> today one of my circuits started to "flicker" occassionally. has me worried.
2014-12-13T10:55:47 < upgrdman> so i went out and decided to try testing the gfcis.
2014-12-13T10:55:59 < upgrdman> all test and reset fine except for the one that will not reset
2014-12-13T10:56:12 < upgrdman> and nothing is plugged into it. and other gfci's on same circuit work fine.
2014-12-13T10:56:20 < PaulFertser> qyx_: might be, yes. We have N and PE tied together just a few meters away from every apartment, I was judging based on that.
2014-12-13T10:57:19 < qyx_> nah, TN-S obligatory here
2014-12-13T10:57:46 < PaulFertser> upgrdman: so it first provided bad connection and now after triggering the RCD it's permanently disconnected?
2014-12-13T10:58:04 < upgrdman> the outlet hasn't had anything plugged into it for >1 year
2014-12-13T10:58:11 < upgrdman> but the circuit it's on... flickers now
2014-12-13T10:58:24 < qyx_> more like TN-C-S, but PEN is usually split in the main electrical box
2014-12-13T10:58:45 < upgrdman> will buy a new GFCI in the morning. and check all outlet's wiring for loose wire or other problems
2014-12-13T10:59:02 < qyx_> do you use copper wiring?
2014-12-13T10:59:08 < upgrdman> yes, copper. not al
2014-12-13T10:59:25 < qyx_> Al likes to do such things
2014-12-13T11:01:32 < PaulFertser> Especially when screwed together with copper :)
2014-12-13T11:03:55 < upgrdman> hmmm http://dangerousprototypes.com/2014/12/12/an-fpga-sprite-graphics-accelerator-with-a-180mhz-stm32f429-controller-and-640-x-360-lcd/
2014-12-13T11:21:11 < ReadError> aluminum wiring??
2014-12-13T11:22:45 < upgrdman> no
2014-12-13T11:23:40 < ReadError> wow i didnt even know that existed
2014-12-13T11:23:49 < PaulFertser> Lucky you :/
2014-12-13T11:23:53 < madist> overhead power lines are all aluminium.
2014-12-13T11:23:58 < madist> steel cored aluminium.
2014-12-13T11:24:15 < upgrdman> all of the wiring in my home is copper
2014-12-13T11:24:38 < upgrdman> the huge fucking wires going into my main breaker panel, the wires for each circuit, and the wires between outlets. all copper.
2014-12-13T11:25:14 < madist> there will be aluminium there somewhere. you just haven't seen it that's all.
2014-12-13T11:26:29 < madist> the underground cable that comes to your building will possibly be aluminium.
2014-12-13T11:26:56 < upgrdman> may be
2014-12-13T11:27:15 < upgrdman> but in my wires, it all appears to be copper
2014-12-13T11:27:21 < upgrdman> s/wires/walls
2014-12-13T11:27:30 < madist> inside the house its all copper.
2014-12-13T11:27:48 < madist> but the heavy distribution lines often use al. saves a lot of money.
2014-12-13T11:27:59 < upgrdman> and for the last hour, the one circuit that was flickering stopped flickering.
2014-12-13T11:28:22 < upgrdman> wonder if this stuck GFCI had anything to do with it. maybe a loose wire or someshit
2014-12-13T11:28:37 < madist> is it stuck or is it tripping immediately ?
2014-12-13T11:28:46 < madist> if its stuck its just broken buy a new one.
2014-12-13T11:29:02 < upgrdman> i pushed the test button, and it tripped, and ever since it will not reset
2014-12-13T11:29:10 < upgrdman> yes, will buy one in the morning
2014-12-13T11:29:16 < upgrdman> its 1:30 am here :)
2014-12-13T11:29:35 < madist> awesome! that means you don't have to spend any money!
2014-12-13T11:29:44 < madist> :p
2014-12-13T11:29:56 < madist> unless your neighbor is awake too.

2014-12-13T13:53:27 < jpa-> decimad2: huh, looks silly indeed
2014-12-13T13:53:43 < jpa-> apparently to avoid undefined behaviour, but c++ is full of it anyway
2014-12-13T13:53:54 < decimad2> it sucks so bad I cannot put it in words
2014-12-13T13:54:36 < jpa-> especially silly as it works without constexpr
2014-12-13T14:03:51 < dongs> https://pbs.twimg.com/media/B4um8wHCcAAxUtV.jpg:large
2014-12-13T14:05:19 < dongs> https://www.kickstarter.com/projects/1181257820/impossible-0 lol
2014-12-13T14:08:27 < jpa-> price seems unrealistic
2014-12-13T14:08:43 < dongs> oh just price?
2014-12-13T14:09:15 < jpa-> well at 10x the price and a few years more, it could probably be done
2014-12-13T14:09:34 < jpa-> and missing the estimated date is just normal for kickstarter
2014-12-13T14:09:43 < decimad2> jpa-: non-constexpr needs out of class initialization and ends up in the initialization list of the startup code...
2014-12-13T14:09:59 < decimad2> jpa-: i consider this a language defect.
2014-12-13T14:10:38 < jpa-> decimad2: well depends, some expressions like (int*)0x1234 gcc will happily make const data for, but will not allow constexpr
2014-12-13T14:10:47 < jpa-> and yeah, i would consider it a language defect also
2014-12-13T14:13:45 < decimad2> well, let's stick to gcc 4.8 until the arm guys suggest a workaround ;)
2014-12-13T14:14:14 < jpa-> arm is using c++ and constexpr now?
2014-12-13T14:14:35 < decimad2> well, they are providing the gcc port, so they must know
2014-12-13T14:14:53 < jpa-> eh
2014-12-13T14:15:08 < jpa-> why would they care if C++ as a language is not perfect?
2014-12-13T14:15:14 < jpa-> it's not like anyone ever believed it was
2014-12-13T14:16:04 < jpa-> the stackexchange-suggested intptr_t is probably the best portable workaround there is
2014-12-13T14:16:17 < decimad2> link?
2014-12-13T14:16:32 < jpa-> http://stackoverflow.com/a/10376574/914716
2014-12-13T14:17:52 < decimad2> ahh, I saw that yes, that is out of question... I can stick with macros then as welll..
2014-12-13T14:18:29 < jpa-> maybe do like zyp does and pass the base address into the constructor?
2014-12-13T14:18:40 < jpa-> then you have a pointer upon which you can build all the other pointers
2014-12-13T14:19:32 < decimad2> I only want to do that if there are multiple peripherals of the same type (and even then I tend to use an index instead of a base pointer)
2014-12-13T14:20:03 < jpa-> well then your wants are causing a problem
2014-12-13T14:20:20 < jpa-> and of what peripheral can you be sure that there is only ever one instance?
2014-12-13T14:20:34 < decimad2> Like for example a core register
2014-12-13T14:21:26 < jpa-> what about dual-core processors? (i don't know how they work anyway..)
2014-12-13T14:22:38 < decimad2> Well, CMSIS defines those registers as "constants" too, all I want to do is this, only in C++ without macros... and obviously I'm asking for pain with this.
2014-12-13T14:22:52 < dongs> ur a macro pain
2014-12-13T14:23:09 < jpa-> IMO rewriting something that works just fine is useless
2014-12-13T14:23:14 -!- ntfreak [~ntfreak@unaffiliated/ntfreak] has quit [Remote host closed the connection]
2014-12-13T14:23:26 < jpa-> like if you want to just "do it exactly like macros, but no macros because someone said macros baaaad"
2014-12-13T14:23:54 < jpa-> whereas providing nice abstraction using c++ makes sense
2014-12-13T14:23:55 < decimad2> Obviously the rest of C++ enables things one cannot do with the macros
2014-12-13T14:24:10 < decimad2> but this is core
2014-12-13T14:25:12 < decimad2> I don't see why one should not try and experiment how it could be if one would not use the way "everybody is used to"
2014-12-13T14:25:48 < jpa-> oh well, that is a fine thing to do
2014-12-13T14:26:07 < jpa-> i just assumed you wanted to get something done instead of playing out with the best way to access a register :)
2014-12-13T14:27:57 < decimad2> jpa-: If I wanted to get shit done quickly, I'd use the copy&paste style coding people seems to do often ;)
2014-12-13T14:28:19 < jpa-> it is not really as effective as one might believe
2014-12-13T14:28:44 < decimad2> anyways, I'm having fun my way and I learn everything about the system, so it's win-win for me ;)
2014-12-13T14:29:03 < decimad2> well obviously this language defect is not so fun
2014-12-13T14:29:22 < jpa-> submit a request for review
2014-12-13T14:31:18 < jpa-> looks like it's been done and rejected   http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_closed.html   1384.
2014-12-13T14:42:36 < decimad2> I don't think there are any chances... they'd reject it with a smart response...
2014-12-13T14:44:15 < decimad2> Yeah, that item seems to relate to this although the request reason is not well stated...

2014-12-13T17:59:21 < Getty> ok, can it be that we cant have nice things cause of not having mmap and munmap?
2014-12-13T18:07:38 < jpa-> more like code written for unix is very rarely useful on a microcontroller
2014-12-13T18:08:38 < jpa-> so far i know of exactly 0 libraries that are in wide use on PC that would be a good fit for a microcontroller
2014-12-13T18:08:49 < jpa-> and only a few that can be made to work at all out-of-the-box
2014-12-13T18:09:36 < Getty> the lib we try to port actually smells totally like microcontroller :( it just sadly using mmap
2014-12-13T18:10:00 < jpa-> so, does not smell like microcontroller at all
2014-12-13T18:10:34 < decimad2> maybe you can get it to work with boost
2014-12-13T18:10:41 < jpa-> luls :)
2014-12-13T18:10:45 < Getty> yeah well, see for yourself: http://www.corpit.ru/mjt/tinycdb/tinycdb-0.78.tar.gz
2014-12-13T18:11:12 < jpa-> i also thought that ustl totally smelled like microcontroller, but apparently not
2014-12-13T18:11:35 < qyx_> so remove the mmap thing
2014-12-13T18:11:35 < emeb> seen this? http://www.st.com/web/en/catalog/mmc/FM141/SC1169/SS1858/PF260794?icmp=pf260  794_pron_pr-stm32f7_sep2014&sc=stm32f756-pr
2014-12-13T18:11:46 < qyx_> also, you prpobably don't have filesystem on your microcontroller
2014-12-13T18:11:54 < qyx_> so mmap is the minor problem here
2014-12-13T18:12:25 < jpa-> so replace cdb_init() and it should work?
2014-12-13T18:12:36 < jpa-> so that it points to a static memory buffer instead
2014-12-13T18:12:38 < qyx_> don't know, never seen the library
2014-12-13T18:12:59 < jpa-> i have, i took a 5 second look at it just now and seems easy to do what qyx_ suggested
2014-12-13T18:13:14 < Getty> cdb_init is actually a part we do need
2014-12-13T18:13:32 < jpa-> huh?
2014-12-13T18:13:33 < decimad2> who is we btw?
2014-12-13T18:13:35 < Getty> so we just remove mmap calls and do.. "something similar ourself"?
2014-12-13T18:13:40 < jpa-> yes, replace it
2014-12-13T18:13:46 < jpa-> it just sets a few pointers
2014-12-13T18:13:46 < Getty> brabo and me
2014-12-13T18:14:10 < Getty> ok, yeah, i was just a bit confused that such a function is just not available, i mean i get it now, still it was awkward
2014-12-13T18:15:41 < brabo> what is the difference between mmap and malloc?
2014-12-13T18:15:54 < brabo> are they very similar or totally not?
2014-12-13T18:16:04 < qyx_> huh?
2014-12-13T18:16:13 < qyx_> they do different things
2014-12-13T18:16:21 < qyx_> see http://en.wikipedia.org/wiki/Mmap
2014-12-13T18:16:43 < Getty> ah... i see
2014-12-13T18:23:27 < brabo> mmm seems non trivial to make that functionality myself
2014-12-13T18:23:56 < qyx_> again, you probably have no files at all on your microcontroller
2014-12-13T18:24:08 < qyx_> but you can simply link your cdb binary to .elf

2014-12-13T18:25:18 < Getty> we use it on a FatFs, and what you mean with binary?
2014-12-13T18:25:21 < qyx_> ok, so it probably wont work as you want
2014-12-13T18:25:26 < Getty> we dont wanna use the binary, we wanna use it as lib inside our code
2014-12-13T18:25:28 < qyx_> binary = cdb file

2014-12-13T18:25:50 < Getty> oh that you mean
2014-12-13T18:25:52 < Getty> and what is now the point?
2014-12-13T18:26:05 < Getty> cdb works with files as storage, "a file" to be specific
2014-12-13T18:26:09 < qyx_> the point is that the library is made to work with memory, not wiles
2014-12-13T18:26:16 < qyx_> *files
2014-12-13T18:26:23 < qyx_> and it uses mmap to map files to memory
2014-12-13T18:27:19 < Getty> on generation
2014-12-13T18:29:07 < qyx_> hm, why have you chosen tinycdb?
2014-12-13T18:29:31 < Getty> lets say, till the mmap it was 100% perfect fitting in all matters, i mean like, what it can do, how much resources it needs, and everything
2014-12-13T18:30:03 < Getty> hey i would love to take an alternative, a key-value storage that uses files on the FatFs
2014-12-13T18:30:21 < Getty> the alternative alternative is.... yeah.... making some own definition about how store all this on the files and blabla
2014-12-13T18:30:38 < Getty> i just REALLY want to avoid this, if all i need is a bunch of key values (which might include complete files)
2014-12-13T18:31:31 < Getty> also i must always think double, as i need the same code also in the perl simulator and the build toolchain to prepare images, which also fits nicely in CDB
2014-12-13T18:31:39 < qyx_> cdb_init uses mmap
2014-12-13T18:31:42 < Getty> technical i have already the CDB files we need to read and everything, this side was easy
2014-12-13T18:31:57 < Getty> yes, that is what we talked about all the time now, why you say it again?
2014-12-13T18:33:15 < qyx_> because you said it uses mmap on generation only
2014-12-13T18:33:30 < Getty> isnt it?
2014-12-13T18:33:42 < qyx_> no, because you need cdb_init to actually access the database
2014-12-13T18:34:09 < qyx_> and you pass it a file descriptor opened for reading
2014-12-13T18:34:30 < Getty> oh ok yeah then we are bigger fucked ;) but whatever the base problem was so or so there as we NEED the generation ;)
2014-12-13T18:35:31 < qyx_> http://zserge.com/jsmn.html
2014-12-13T18:35:32 < qyx_> see
2014-12-13T18:35:34 < qyx_> for example
2014-12-13T18:35:42 < qyx_> generating json is very straightforward
2014-12-13T18:35:42 < Getty> yeah but we cant store anything in the JSON
2014-12-13T18:35:45 < Getty> i know this
2014-12-13T18:35:45 < Getty> yes
2014-12-13T18:35:47 < Getty> all on the scpe
2014-12-13T18:36:09 < qyx_> what can't you store in a json?
2014-12-13T18:36:10 < Getty> but how does jsmn react to a 1MB JSON file? it would have to read it all through
2014-12-13T18:36:18 < qyx_> cdb also
2014-12-13T18:36:23 < qyx_> actually cdb uses mmap for tat
2014-12-13T18:36:44 < Getty> well then all the benchmarks are lieing ;) it is called to be using low memory
2014-12-13T18:37:21 < qyx_> how did you come to a conclusion it needs to read the whole json?
2014-12-13T18:37:47 < Getty> yeah well, validity, it needs to be at least doing a lot of parsing in the process to get to a deeper point
2014-12-13T18:37:54 < Getty> we could try it out how it works out
2014-12-13T18:38:24 < qyx_> but yes, it wants pointer to char *
2014-12-13T18:38:28 < Getty> i can switch to a json file on the generation and then see
2014-12-13T18:38:30 < qyx_> so two options here
2014-12-13T18:38:35 < qyx_> you can either read the whole file
2014-12-13T18:38:37 < qyx_> or use mmap
2014-12-13T18:38:41 < qyx_> and you are here again
2014-12-13T18:39:10 < qyx_> also fatfs doesn't have posix interface for accessing files
2014-12-13T18:39:25 < qyx_> so probably all libraries you can find will not work out of box
2014-12-13T18:39:31 < qyx_> even if they are not using mmap
2014-12-13T18:40:27 < Getty> ok another good point ;) so in the end we come to the "own system" solution, meh
2014-12-13T18:40:35 < Getty> just annoying
2014-12-13T18:41:17 < qyx_> also i wish you luck if you need to randomly search/seek in 1MB file using fatfs :P
2014-12-13T18:41:21 < qyx_> without cache
2014-12-13T18:41:32 < qyx_> and without ordered keys
2014-12-13T18:41:38 < qyx_> or indes or whatever

2014-12-13T20:31:04 < bvernoux> work perfectly on GCC ARM 4.7

2014-12-13T21:03:14 < bvernoux> ha ok it's the 1st 4.9 release too ;)
2014-12-13T21:10:08 < upgrdman> Taxman: i sample as high as possible so i can average and get decent ENOB
2014-12-13T21:10:35 < upgrdman> but 25Hz seems like a reasonable lower limit if you don't need resolution
2014-12-13T21:11:26 < Taxman> my rtp is very high impedance

2014-12-13T21:12:52 < bvernoux> Laurenceb_: check your isr handler ;)
2014-12-13T21:12:57 < upgrdman> seems like a bad idea to use caps
2014-12-13T21:13:03 < bvernoux> Laurenceb_: for me they are all removed .... even if declared
2014-12-13T21:13:06 < upgrdman> you don't want to average in the non-tounched state
2014-12-13T21:13:24 < Laurenceb__> bvernoux: probably some issue with your project setup?
2014-12-13T21:13:27 < Laurenceb__> all works fine for me
2014-12-13T21:13:28 < upgrdman> you want to take many samples and see if many of them are in ~same place
2014-12-13T21:13:44 < Taxman> upgrdman: So no caps on the port pins?
2014-12-13T21:13:47 < Laurenceb__> smaller code and slightly faster
2014-12-13T21:13:51 < upgrdman> Taxman: correct
2014-12-13T21:13:53 < bvernoux> Laurenceb_: all isr handler are defined in a table with weak attribute and that work fine with GCC 4.7
2014-12-13T21:14:01 < Laurenceb__> hmmm
2014-12-13T21:14:17 < bvernoux> maybe they have changed something in GCC 4.9 ...
2014-12-13T21:14:29 < Laurenceb__> old (non commercial) version of my project is on github
2014-12-13T21:14:41 < bvernoux> my handler are defined in C code too not like example in an asm file for the table

2014-12-13T21:15:51 < Laurenceb__> yeah
2014-12-13T21:16:02 < bvernoux> i have never seen this attribute
2014-12-13T21:16:20 < Laurenceb__> yeah its needed to stop them being optimised out
2014-12-13T21:16:34 < bvernoux> hmm maybe it's the solution ;)
2014-12-13T21:17:28 < Laurenceb__> well that project def compiles well with 4.9 compared to 4.7
2014-12-13T21:18:02 < bvernoux> I was using
2014-12-13T21:18:02 < Laurenceb__> ~50k as opposed to ~56
2014-12-13T21:18:03 < Laurenceb__> and a few % faster
2014-12-13T21:18:04 < bvernoux> __attribute__((naked))
2014-12-13T21:18:15 < jpa-> yeah, you need externally_visible
2014-12-13T21:18:28 < jpa-> why would you use "naked" attribute?
2014-12-13T21:18:40 < jpa-> unless your interrupt is written in assembler

2014-12-14T02:28:42 < decimad2> So it took me a while but as it seems STM is actually only instancing what ARM provides as HDL (thought that would only be the core)... I was curious about how the AHB<->APB bridge works, found http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0479b/BABFADAI.html . So if I interpret this correctly then there can be exactly one read and one write at any time, but those two run concurrrently? Does the Core halt until
2014-12-14T02:28:42 < decimad2> the transactions are done or is the data buffered for delivery?
2014-12-14T02:40:30 < dongs> yeah STM is just using existing IP
2014-12-14T02:40:36 < dongs> if the arm docs say, then thats what it does

2014-12-14T04:35:46 < GargantuaSauce_> i wonder how many enums there are for logic 0/1 in total
2014-12-14T04:37:10 < varesa> Checked once again, it goes to the init_board() and then loops in the while(1)
2014-12-14T04:37:16 < GargantuaSauce_> huh.
2014-12-14T04:41:46 < GargantuaSauce_> well lets rule out stdperiphlib stupidity. RCC->AHBENR |= RCC_AHBENR_GPIOBEN; GPIOB->MODER |= 1; GPIOB->BSRR=1;

2014-12-14T04:53:49 < GargantuaSauce_> on the plus side if you ever want to enable dma1 and have wonderfully obfuscated code, that's a great way to do it

2014-12-14T04:58:09 < karlp> emeb_mac: somehow everything was going to be original, because that was important for sound, but not these pot sliders, they were too expesive
2014-12-14T04:58:42 < emeb_mac> karlp: I've seen those arp2600 kits/plans out there. It's pretty crazy stuff.
2014-12-14T04:59:18 < emeb_mac> I like the sound of that synth, but not for the kind of trouble/hassle that is needed to build these new replicas
2014-12-14T04:59:34 < karlp> I actually had someone talk to me about "bright" vs "dull" sound from different versions of some oscillator
2014-12-14T04:59:51 < karlp> that is buried in some footnote of some version of it

2014-12-14T05:00:35 < emeb_mac> I suppose that's possible - but anyone who uses the oscillator w/o other processing is doing it wrong.
2014-12-14T05:00:56 < emeb_mac> if it's too bright, run it through a filter or waveshaper.
2014-12-14T05:01:00 < GargantuaSauce_> yeah if the harmonics are different just adjust the filter...
2014-12-14T05:01:13 < GargantuaSauce_> or perhaps add a little bit of overdrive/distortion before the filter
2014-12-14T05:02:00 < emeb_mac> The synth world is full of superstitious beliefs - folks who think that thru-hole / DIP parts color the sound.

2014-12-14T05:02:55 < GargantuaSauce_> wellll the socketed opamps makes a little bit of sense, because different ones do behave differenty and then you can experiment a bit
2014-12-14T05:03:27 < emeb_mac> that's valid
2014-12-14T05:03:51 < emeb_mac> although gigging with socketed equipment is problematic
2014-12-14T05:04:18 < GargantuaSauce_> is a dip really going to fall out of a socket in transport??
2014-12-14T05:04:33 < emeb_mac> It's pretty common actually.
2014-12-14T05:04:36 < GargantuaSauce_> huh.
2014-12-14T05:04:42 < GargantuaSauce_> well there's always hotglue

2014-12-14T05:05:25 < emeb_mac> MemoryMoogs are notorious because they use IDC cables in DIP sockets
2014-12-14T05:05:36 < emeb_mac> and the cables are always falling out
2014-12-14T05:05:52 < GargantuaSauce_> yeah cables i can see that happening to, cause they actually have some inertia and can flop around
2014-12-14T05:10:22 < dongs> timecube way of initializing RCC is fool-proof
2014-12-14T05:10:28 < dongs>     __SPI1_CLK_ENABLE();
2014-12-14T05:10:28 < dongs>     __GPIOA_CLK_ENABLE();
2014-12-14T05:10:32 < dongs> cuz now you can't mix htem
2014-12-14T05:10:43 < dongs> so if you wanna turn on ilek 10 peripherls, youre gonna have 10 lines of shit t here
2014-12-14T05:11:22 < emeb_mac> and a function call for each one, unless they're inlined.
2014-12-14T05:11:36 < dongs> #define __SPI1_CLK_ENABLE()     (RCC->APB2ENR |= (RCC_APB2ENR_SPI1EN))
2014-12-14T05:11:50 < varesa> oh, I though the cube only generated code that uses those stdperiphlib functions
2014-12-14T05:11:59 < dongs> it does.
2014-12-14T05:12:02 < englishman> does it still compile to 1 line
2014-12-14T05:12:04 < dongs> thats what it generates
2014-12-14T05:12:17 < dongs> englishman: i doubt compiler will be able to combine
2014-12-14T05:12:20 < dongs> ie if youre doing
2014-12-14T05:12:26 < dongs> #define __USART1_CLK_ENABLE()   (RCC->APB2ENR |= (RCC_APB2ENR_USART1EN))
2014-12-14T05:12:28 < dongs> and SPI1
2014-12-14T05:12:31 < dongs> and th ey're both on apb2enr
2014-12-14T05:12:43 < emeb_mac> compiler shouldn't combine - it must assume you meant to do the ops in that order
2014-12-14T05:12:52 < englishman> right
2014-12-14T05:12:55 < dongs> well then.
2014-12-14T05:13:31 < varesa> though aren't compilers able to reorder some stuff if/when optimizing?
2014-12-14T05:13:54 < varesa> or is writing into registers like those an exception?
2014-12-14T05:14:06 < dongs> they're all volatile
2014-12-14T05:14:15 < dongs> so that's probly why it wont combine/reorder
2014-12-14T05:14:30 < varesa> propably yeah
2014-12-14T05:15:50 < varesa> I just remember reading a long issue thread on github about the compiler deciding to reorder a few instructions regarding RTOS and some locks/mutexes, e.g. swap an action and taking a lock for that action or somtehing

2014-12-14T06:03:41 < GargantuaSauce_> the onboard ldo might end up fighting with the external source

2014-12-14T06:04:00 < GargantuaSauce_> might be pertinent to desolder it or cut the trace
2014-12-14T06:05:16 < englishman> what's the purpose of feeding 3v to the board while usb is in? just leaving something connected?
2014-12-14T06:05:49 < yan_> one of the ic's i'm using is 3.3v max. i am providing 3v from a power supply, but i still want to debug via usb
2014-12-14T06:06:37 < englishman> there's probably a solderjumper, or maybe that Idd jumper
2014-12-14T06:06:50 < yan_> that Idd jumper cuts off power from everything
2014-12-14T06:06:52 < yan_> i tried that first
2014-12-14T06:07:19 < englishman> user manual has a schematic btw
2014-12-14T06:08:41 < GargantuaSauce_> think there are a few 0 ohm resistors along the power supply also
2014-12-14T06:11:54 < yan_>  hm i can use the st-link portion as an external application and just wire it below via jumpers
2014-12-14T06:12:12 < GargantuaSauce_> and you can probably pull like 80-100mA from the discovery's 3v rail for the external thing
2014-12-14T06:12:38 < yan_> i'm not intending to pull a lot of amperage, i just don't want logic to exceed 3v
2014-12-14T06:12:56 < upgrdman> or just rig up a nice big regulator like this: http://www.farrellf.com/temp/stlink_chopped_pcb.jpg  (without chopping up your board)
2014-12-14T06:16:32 < GargantuaSauce_> stick a 1k resistor or something across the 3v pin on the discovery to ground and measure its voltage
2014-12-14T06:16:43 < GargantuaSauce_> there's a diode there which should drop it to 3V from 3.3
2014-12-14T06:16:53 < GargantuaSauce_> oh you're worried about the io, duh
2014-12-14T06:17:39 < GargantuaSauce_> actually everything is powered through that diode

2014-12-14T06:40:47 < GargantuaSauce_> yes, unless you don't tie the external stuff to the 3v pin of the discovery at all
2014-12-14T06:41:31 < yan_> unless what?
2014-12-14T06:42:02 < GargantuaSauce_> don't supply 3V to the discovery
2014-12-14T06:42:41 < GargantuaSauce_> or alternatively, let the discovery power your external stuff
2014-12-14T06:44:53 < yan_> GargantuaSauce_: that was the problem, if discovery powers my stuff, it'll get 5. if i supply 3v to the EXT_3V pin, debugging seems to be working and logic and is providing +3v to i2c .. unless i2c is being pulled up by the external sensor (which is getting Vcc from external power as well) and discovery is just pulling it down
2014-12-14T06:45:02 < GargantuaSauce_> what?
2014-12-14T06:45:12 < GargantuaSauce_> why will it get 5V
2014-12-14T06:45:24 < yan_> USB provides 5v to discovery
2014-12-14T06:46:41 < GargantuaSauce_> .........
2014-12-14T06:46:45 < yan_> let me step back. when using discovery from usb, logic+vcc is at 5v. i want logic to be at 3v.
2014-12-14T06:46:54 < dongs> uhhhhhhhhhhhhh
2014-12-14T06:46:56 < GargantuaSauce_> no logic is running at 5V

2014-12-14T06:47:47 < englishman> or maybe the stm32 datasheet
2014-12-14T06:48:08 < yan_> oooooh fuck me. i was tying EXT_5V to Vcc of the external sensor, which is by definition 5v
2014-12-14T06:48:15 < yan_> and then forgot that i did that
2014-12-14T06:48:20 < yan_> then it was pulling up i2c to 5v
2014-12-14T06:49:20 < GargantuaSauce_> the mcu will be fine with that. if you need another i2c at 3V then you just need to use a second i2c perpheral
2014-12-14T06:49:58 < yan_> actually this specific peripheral is fine at 5v, but i am using another SPI one that isnt'
2014-12-14T06:50:06 < yan_> anyway, major oversight on my part
2014-12-14T06:50:21 < GargantuaSauce_> yeah so use the discovery board's 3V rail to power that and don't bother with an external supply at all
2014-12-14T06:50:57 < yan_> that's what i'm doing now
2014-12-14T06:50:59 < GargantuaSauce_> k
2014-12-14T06:56:25 < qyx_> meh that omnivision sensor
2014-12-14T06:56:49 < qyx_> why are all implementation writing to reserved bytes and where did they get any documentation of them
2014-12-14T06:56:52 < qyx_> *s

2014-12-14T08:44:27 < yan_> Outside of peripheral clocks and GPIO alternate function, do i need to enable anything else for SPI to work? (stm32l1x)
2014-12-14T08:48:00 < yan_> trying this at the moment: https://gist.github.com/anonymous/cee3bf80f6217b0fd0ee (i also asked this in #libopencm3)
2014-12-14T08:49:45 < dongs> yan, loks ok
2014-12-14T08:50:00 < yan_> dongs: i have my scope on SCK and NSS and they both stay low
2014-12-14T08:50:18 < dongs> i didnt think nss mattered with spi unless slave
2014-12-14T08:50:22 < dongs> you just use any random gpio for it
2014-12-14T08:50:31 < dongs> anyway, clk should be moving at least.
2014-12-14T08:52:08 < yan_> dongs: even if i have a disconnected IC (i don't, but for sake of argument), it should still at least provide a clock, right?
2014-12-14T09:09:59 < dongs> sure
2014-12-14T09:10:00 < dongs> if its master
2014-12-14T09:11:16 < yan_> hm. i just tried a different SPI device, and that's working
2014-12-14T09:11:52 < dongs> oh
2014-12-14T09:11:59 < dongs> the other shit could be pulling the stuff low?
2014-12-14T09:12:03 < dongs> -> so clk doent move etc.
2014-12-14T09:17:33 < yan_> could be, need to go deeper into the specsheet.. was just trying to confirm connectivity first

2014-12-14T10:31:57 < jpa-> of course
2014-12-14T10:32:42 < jpa-> though on F1 peripherals reserve all the pins that you have enabled, so even if you don't need NSS on spi or similar, it will take it
2014-12-14T10:33:01 < jpa-> (away from other peripherals, not away from gpio though)
2014-12-14T10:33:20 < yan_> hm weird. i havea an i2c peripheral on a few pins and a spi peripheral on other pins (both GPIOB).. the spi peripheral does not work if i2c is enabled/configured
2014-12-14T10:33:42 < jpa-> how do you configure the GPIOB AFIO registers?
2014-12-14T10:34:07 < jpa-> each pin has its own configuration, take care not to mess the spi pins when you configure i2c
2014-12-14T10:34:08 < yan_> jpa-: gpio_set_af(GPIOB, GPIO_AFX, PIN_MASK)
2014-12-14T10:34:18 < yan_> er, sorry, i do it via libopencm3
2014-12-14T10:34:33 < jpa-> what is PIN_MASK?
2014-12-14T10:34:47 < yan_> GPIO5 | GPIO6 , etc
2014-12-14T10:35:51 < jpa-> check the GPIO registers in debugger after the config and compare with reference manual

2014-12-14T15:02:05 < dongs> With the drive removed, we see the entire logic board for the first time. The height of 1988 technology! Note the single custom QFN package ASIC. That was a pretty big deal at a time when everything was still DIPs, and sometimes even still socketed (as we can see here). Most older Apple IIs were all socketed DIPs, so the IIc represents a shift toward modern manufacturing as well.

2014-12-14T15:11:02 < scummos> it's even worse with those apostrophes in German, because there it is almost always (99%+ of cases) wrong to use one and still people use it like everywhere
2014-12-14T15:11:10 < scummos> in English there are at least a lot of legitimate cases

2014-12-14T17:54:18 < jpa-> Getty: so how can you make it work without replacing the function and still not needing mmap?
2014-12-14T17:55:00 < Getty> jpa: because its an optional interface
2014-12-14T17:55:08 < Getty> jpa: the author told us the ones we should use, that all dont use mmap
2014-12-14T17:55:32 < Getty> jpa: there are in the lib actually 3 read interfaces and 2 create interfaces, and only one of every is needing mmap
2014-12-14T17:55:40 < Getty> so you can do all functionality of cdb without touching one mmap
2014-12-14T17:55:50 < Getty> (its just slightly slower of course)
2014-12-14T17:56:27 < jpa-> umm.. why of course? why is it slower?
2014-12-14T17:56:46 < jpa-> and which is this other interface?
2014-12-14T18:00:20 < jpa-> i don't see why it would be slower, accessing data already in ram should be only faster than mmap
2014-12-14T18:06:31 < qyx_> how can be dma location in the circular buffer restarted?
2014-12-14T18:06:54 < qyx_> do i need to disable it and reenable it?
2014-12-14T18:07:03 < jpa-> i would assume so
2014-12-14T18:07:04 < qyx_> mhm, seems logical
2014-12-14T18:07:15 < jpa-> i think ref man says you cannot write to the regs when channel is enabled
2014-12-14T18:07:34 < Getty> jpa: its slower in the way that it needs to "reread" the TOC for every query, while in other case, it has it stored in memory and so can access it more directly
2014-12-14T18:07:45 < Getty> why you talk about "data in ram"?
2014-12-14T18:07:54 < Getty> we have 32k ram and the file we tlak about is like 1MB< or so
2014-12-14T18:07:56 < Getty> we cant read the file in the ram, ever
2014-12-14T18:08:02 < jpa-> ok
2014-12-14T18:08:16 < Getty> if we could put all data in RAM i think i wouldnt be sitting here talking about problems ;-))))
2014-12-14T18:08:30 < qyx_> still the question is how you would use this file if the library expects different api
2014-12-14T18:08:39 < jpa-> apparently it doesn't
2014-12-14T18:08:41 < Getty> hu? "different api"
2014-12-14T18:08:47 < Getty> we talk about different interfaces
2014-12-14T18:08:48 < jpa-> the library apparently provides several access modes
2014-12-14T18:08:54 < Getty> to the same base structure of CDB files
2014-12-14T18:08:56 < Getty> yes
2014-12-14T18:09:10 < jpa-> though i didn't see the other interfaces in the total 10 seconds i have so far spent looking at it
2014-12-14T18:09:14 < Getty> its actually explained in the manpage of the libcdb ;) but ... who reads that? hahaha
2014-12-14T18:09:27 < qyx_> i  mean different api for accessing files
2014-12-14T18:09:28 < Getty> yeah we spent more time looking at it, we should have just started reading the DOC of the lib itself
2014-12-14T18:10:30 < jpa-> http://man.devl.cz/man/3/cdb   query mode 1 vs. 2, i must admit it is not obvious from the function naming that they are separate interfaces
2014-12-14T18:16:04 < qyx_> wtf, chibios DMAStreamDisable is not the reverse of DMAStreamEnable
2014-12-14T18:16:13 < qyx_> if you disable it, you cannot enable it again
2014-12-14T18:16:43 < jpa-> chibios statemachines are sometimes quite confusing
2014-12-14T18:17:05 < qyx_> theres nothing about state machines, it simply sets other registers and disables interrupts
2014-12-14T18:17:13 < qyx_> but enable doesn't enable them again
2014-12-14T18:18:49 < jpa-> hmm, for stm32f1xx (first that i checked) it only seems to clear the interrupt, not disable it
2014-12-14T18:19:27 < qyx_> it also clears HTIE, TCIE and such
2014-12-14T18:19:36 < qyx_> and then EN
2014-12-14T18:19:45 < jpa-> which stm32?
2014-12-14T18:19:48 < qyx_> F4
2014-12-14T18:20:23 < qyx_> for F1 it does the same
2014-12-14T18:21:15 < jpa-> funny, it does indeed in latest dev version
2014-12-14T18:21:20 < jpa-> in docs it doesn't  http://chibios.sourceforge.net/docs/hal_stm32f4xx_rm/group___s_t_m32_f4xx___d_m_a.html#ga9c635c5c2baaf634036e4a0d71f92a53

2014-12-15T02:40:50 < upgrdman> i bought a real model m on ebay for $60 or $70 a little while back
2014-12-15T02:41:00 < gxti> modern mechanical keyboards are not buckling springs, however if you really want a model m, unicomp sells modernized ones
2014-12-15T02:41:17 < gxti> if you want something with cherry switches there are dozens of chocies. rosewill has a decent one that looks like a plain keyboard.
2014-12-15T02:41:29 < upgrdman> cherry != buckling?
2014-12-15T02:42:25 < gxti> i thought not. i could be wrong.
2014-12-15T02:42:44 < upgrdman> the cherry i felt in store felt and sounds just like a model m
2014-12-15T02:42:45 < gxti> they come in half a dozen different varieties, some of which are neither tactile nor noisy, which would be challenging to do with the same tech as a model m
2014-12-15T02:42:46 < PeterM> unicomp want $100 shipping ona $80 keyboard, fuck that
2014-12-15T02:42:58 < upgrdman> super clicky, lovely tactile response, etc.
2014-12-15T02:43:31 < upgrdman> if you live near a frys or microcenter, you can cop a fell in store
2014-12-15T02:44:44 < PeterM> yeah, i dont see that heppning, i live in the middle of nowhere australia

2014-12-15T02:49:56 < upgrdman> TIL digikey sells keyboards
2014-12-15T02:52:48 < gxti> cherry makes the key switches that the vast majority of mechanical keyboards use, but i don't think many individuals actually buy key*boards* from them
2014-12-15T02:54:14 < gxti> ugh, newegg gets worse to use every time i go there

2014-12-15T02:58:22 < gxti> classy.
2014-12-15T02:59:32 < gxti> anyway, i don't know what newegg charges to ship to the outback, but here's the highest rated mechanical keyboards on newegg: http://www.newegg.com/Product/ProductList.aspx?Submit=Property&N=100052167%20600486769%20600470467%20600470469%20600470471%20600470468%20600516162%208000&IsNodeId=1&name=Newegg
2014-12-15T02:59:37 < gxti> many < $100 USD
2014-12-15T03:04:02 < PeterM> this may seem like an odd request but does someone make them in anything other than black or dark dark grey?

2014-12-15T07:38:20 < GargantuaSauce_> might be because it's a turnkey solution or whatever too

2014-12-15T08:00:41 < GargantuaSauce_> the main issue past basic stability is collision avoidance i think
2014-12-15T08:00:46 < GargantuaSauce_> and that is 100% human
2014-12-15T08:01:33 < GargantuaSauce_> yes and it's dangerous as fuck
2014-12-15T08:02:10 < GargantuaSauce_> because with a turnkey solution like that, knowing what you're doing stops being the limiting factor
2014-12-15T08:02:25 < GargantuaSauce_> you buy it and fly it without any requirement of basic competence
2014-12-15T08:03:06 < GargantuaSauce_> ive been on the fence about this for a long time but i am beginning to think regulation/licensing is necessary
2014-12-15T08:03:21 < GargantuaSauce_> as long as it's accessible
2014-12-15T08:04:14 < GargantuaSauce_> yeah or getting a special permit to do otherwise after having your gear and skills vetted, perhaps

2014-12-15T08:07:20 < upgrdman> would planters set up in front of wall help?
2014-12-15T08:07:22 < emeb_mac> their parents insurance paid to have the wall repaired
2014-12-15T08:07:42 < GargantuaSauce_> liability insurance being a requirement for flying might be good also
2014-12-15T08:07:49 < emeb_mac> upgrdman: I thought about installing concrete bollards
2014-12-15T08:07:53 < upgrdman> like the kind of planters used to keep suicide bomber trucks away :)
2014-12-15T08:07:56 < emeb_mac> but that would probably lead to lawsuits
2014-12-15T08:08:03 < upgrdman> mmm
2014-12-15T08:08:04 < upgrdman> :(
2014-12-15T08:08:26 < emeb_mac> "My baby crashed into your nasty bollard - you owe me!"
2014-12-15T08:08:51 < GargantuaSauce_> i think you underestimate the litigation culture R2COM
2014-12-15T08:08:51 < upgrdman> lol
2014-12-15T08:09:00 < emeb_mac> R2COM: maybe so, but this is 'murica and you can sue for any reason.
2014-12-15T08:09:44 < emeb_mac> If it looks like I did anything special to protect myself then they'd be more likely to blame me.
2014-12-15T08:10:05 < jpa-> so plant a few trees? or too little spacE?
2014-12-15T08:10:23 < emeb_mac> jpa-: I have trees outside the wall - they wen through them like butter
2014-12-15T08:10:40 < emeb_mac> and paid to replace them too. :)
2014-12-15T08:11:03 < emeb_mac> It's "fun"
2014-12-15T08:11:15 < emeb_mac> We had the same mason repair the wall both times
2014-12-15T08:11:19 < emeb_mac> he laughed
2014-12-15T08:11:22 < jpa-> huh, they were going fast then :)
2014-12-15T08:11:24 < emeb_mac> the second time
2014-12-15T08:11:48 < jpa-> maybe build the wall to a different angle so it deflects the cars :P
2014-12-15T08:11:51 < emeb_mac> jpa-: probably going about 20MPH when they hit
2014-12-15T08:12:13 < emeb_mac> one almost made it across the yard to the house
2014-12-15T08:12:25 < emeb_mac> R2COM: I called the police
2014-12-15T08:12:33 < emeb_mac> who came and cited them.
2014-12-15T08:12:45 < emeb_mac> I asked if they were OK - they were, but dazed.
2014-12-15T08:12:55 < jpa-> 20mph isn't that fast.. you need bigger trees :)
2014-12-15T08:13:16 < emeb_mac> R2COM: just dumb kids. No need to get nasty.
2014-12-15T08:14:11 < emeb_mac> I believe it
2014-12-15T08:14:46 < emeb_mac> pretty soon - statistics on people killed by falling drones. :)

2014-12-15T08:17:51 < emeb_mac> so cynical
2014-12-15T08:17:54 < emeb_mac> so right
2014-12-15T08:20:30 < emeb_mac> R2COM: doubt there's any of those in gov't

2014-12-16T02:27:17 < ds2> the test probe
2014-12-16T02:27:30 < ds2> the red one is falling apart right in front of me
2014-12-16T02:27:34 < ds2> in more then one place
2014-12-16T02:27:37 < dongs> oh.
2014-12-16T02:27:40 < dongs> like plastic?
2014-12-16T02:27:48 < dongs> like its 30 years old
2014-12-16T02:27:48 < ds2> like potato crisps :(
2014-12-16T02:27:55 < ds2> except it is about 1 year old
2014-12-16T02:27:56 < dongs> this new office im cleaning up
2014-12-16T02:28:03 < dongs> hasnt had anyone there since 2000
2014-12-16T02:28:08 < dongs> there was a TV antenna plug
2014-12-16T02:28:17 < dongs> i touched it and the plastic just disintegrated
2014-12-16T02:28:41 < dongs> shattered into small pieces almost completely
2014-12-16T02:28:45 < ds2> you guys have working OTA in JP?
2014-12-16T02:29:03 < dongs> heh yeah, they turned off analog few years ago. havce some shitty local digital channels everwehre
2014-12-16T02:29:20 < ds2> what standard you guys use?
2014-12-16T02:29:28 < dongs> japtv, of course
2014-12-16T02:29:31 < dongs> ISDB-T
2014-12-16T02:29:39 < ds2> is that different from DVB-T?
2014-12-16T02:29:46 < dongs> their own trashy standard that they try to push on poor third world countries
2014-12-16T02:29:48 < dongs> of course.
2014-12-16T02:29:51 < dongs> completely different modulation
2014-12-16T02:29:59 < ds2> and nothing like ATSC either?
2014-12-16T02:30:00 < dongs> mpegts layer is ~similar
2014-12-16T02:30:02 < dongs> nope
2014-12-16T02:30:09 < ds2> sigh
2014-12-16T02:30:13 < dongs> well, it is ~similar to dvb in that its OFDM
2014-12-16T02:30:32 < dongs> but ISDB is band-segmented ofdm, some extra crap and y ou can mix ofdm + qpsk in same channel
2014-12-16T02:30:48 < dongs> but totally different from atsc/8vsb stuff
2014-12-16T02:31:11 < ds2> wonder if anyone makes a universal digital tuner anymore
2014-12-16T02:31:25 < dongs> yes but you dont need it
2014-12-16T02:31:44 < ds2> ?
2014-12-16T02:31:54 < dongs> http://www.dektec.com/Products/PCIe/DTA-2131/index.asp
2014-12-16T02:31:56 < dongs> its just SDR
2014-12-16T02:32:00 < dongs> and they have software decode for * mods
2014-12-16T02:32:03 < ds2> oh
2014-12-16T02:36:16 < dongs> anyway, theres generally no reason to have multi-standard receiver
2014-12-16T02:36:19 < dongs> there's also the uh
2014-12-16T02:36:30 < dongs> Dibcom/Parrot dib10000 stuff
2014-12-16T02:36:45 < dongs> which is just single chip sdr-esque thing where you load firmware/dsp to decode whatever
2014-12-16T02:36:51 < dongs> that one is acutally used in  consumer shit
2014-12-16T02:36:54 < dongs> also Siano-MS has something
2014-12-16T02:37:21 < dongs> but generally itsslightly more expensive than single-purpose stuff so wht would manufacturer choose that for more cost and little benefit
2014-12-16T02:37:48 < ds2> no point if it is SDR based
2014-12-16T02:38:13 < upgrdman> this is like the cheapest stm32, right? http://www.mouser.com/ProductDetail/STMicroelectronics/STM32F030F4P6/?qs=sGAEpiMZZMvmogu7fABzFrSMzDNNd1sa
2014-12-16T02:38:51 < dongs> ds2: mean?
2014-12-16T02:39:30 < dongs> ds2: sdr is still more power consumption than dedicated demodulation silicon
2014-12-16T02:39:47 < dongs> so you get no visible benefit to users but your shit uses more power
2014-12-16T02:39:49 < ds2> yes.
2014-12-16T02:40:02 < ds2> only makes sense if someone made a hard core that did all the standards
2014-12-16T02:40:05 < dongs> and it generalyl costs more (i.e. from my experience with both dibcom and siano stuff)
2014-12-16T02:41:58 < emeb> only advantage would be multi-markets w/ same board design, and at high volume there's no incentive for that.
2014-12-16T02:42:25 < dongs> right
2014-12-16T02:42:32 < dongs> dicks here actually did a 'multi-market' board
2014-12-16T02:42:34 < emeb> esp considering that the RF frequencies are likely different.
2014-12-16T02:42:37 < dongs> but we just used like 3 different demod chips
2014-12-16T02:42:38 < dongs> lolz.
2014-12-16T02:43:00 < emeb> haha
2014-12-16T02:43:01 < dongs> seriosuly that was cheaper than something reconfigurable
2014-12-16T02:43:13 < emeb> Just loaded different parts of the board?
2014-12-16T02:43:18 < dongs> nope, loaded all of them
2014-12-16T02:43:38 < emeb> and turn on the ones you want for any given situation...
2014-12-16T02:43:41 < dongs> yeah
2014-12-16T02:43:56 < emeb> probably cost about the same as a multi-std chip
2014-12-16T02:44:10 < dongs> it had some chiense thing for DTMB/CMMB, panasonic chip for dvb-t/c/t2, another panasonic thing for atsc
2014-12-16T02:45:26 < emeb> those folks making realtek DVB-T USB dongles probably never suspected they'd be so popular in the US now that all the SDR geeks are buying them.
2014-12-16T02:45:33 < dongs> heh yeah
2014-12-16T02:45:53 < dongs> which remidns me i have a tray of uncommon realtek thing, it has sdr + dvb-t + serial ts input
2014-12-16T02:46:02 < emeb> nifty
2014-12-16T02:46:10 < dongs> (RTL8193P or someshit, the -common one is -U suffix
2014-12-16T02:46:17 < dongs> been meaning to m ake something with it
2014-12-16T02:46:53 < emeb> so it has ts output instead of usb?
2014-12-16T02:46:59 < dongs> input
2014-12-16T02:47:04 < dongs> so it can get ts from somewehre else also
2014-12-16T02:47:14 < emeb> ah - also ts input. what for output?
2014-12-16T02:47:20 < dongs> usb, as usual
2014-12-16T02:47:24 < emeb> kk
2014-12-16T02:47:40 < emeb> wonder what that would be good for...
2014-12-16T02:47:52 < emeb> alternate demod or something...
2014-12-16T02:47:56 < dongs> yes
2014-12-16T02:48:06 < dongs> or in my case would be japtv + SDR
2014-12-16T02:48:13 < emeb> ya
2014-12-16T02:48:15 < dongs> (and dvbt, but nobody needs that)
2014-12-16T02:48:28 < emeb> is that used in china too or just europe?
2014-12-16T02:48:34 < dongs> eruope
2014-12-16T02:48:39 < dongs> chian is DTMB or whatever
2014-12-16T02:48:44 < emeb> naturally
2014-12-16T02:48:48 < dongs> did you know china actually made their own h264-like video encoding
2014-12-16T02:48:54 < emeb> "mine do it mine self"
2014-12-16T02:49:05 < emeb> haha - get around the patents
2014-12-16T02:49:48 < dongs> forgot waht ethe fuck the naem was
2014-12-16T02:49:55 < dongs> i had to look it up few weeks ago because apparently its acutally in use
2014-12-16T02:49:59 < dongs> and someone needed
2014-12-16T02:50:18 < emeb> they make codec chips?
2014-12-16T02:50:26 < dongs> of course
2014-12-16T02:50:44 < dongs> and they have reference encoder/decoder sores etc.
2014-12-16T02:50:53 < emeb> for PCs
2014-12-16T02:51:07 < emeb> what's the license like?
2014-12-16T02:51:28 < dongs> lemme just find the shit and then you can check it yourself
2014-12-16T02:51:36 < dongs> trying to remmber which workdick asked about this
2014-12-16T02:52:15 < dongs> 'AVS'

2014-12-16T02:53:40 < dongs> loll'ing
2014-12-16T02:54:00 < dongs> i think they had sores on either shithub or soundrofgge or somethign
2014-12-16T02:54:08 < emeb> royalty: $0.10/unit
2014-12-16T02:54:11 < dongs> anyway, i stopped caring shortly after the conversation so thats all I can find
2014-12-16T02:54:21 < upgrdman> anyone here bought from Future Electronics?
2014-12-16T02:54:48 < emeb> "the future is here, it's just unevenly distributed"
2014-12-16T02:55:29 < emeb> upgrdman: cute little tssop STM32. Not much there though.
2014-12-16T02:55:46 < emeb> probably "PIC Killer"
2014-12-16T02:55:51 < emeb> but not cheap enough
2014-12-16T02:56:22 < upgrdman> emeb: ya. tempted to get them for those little jobs that don't really require a uc. (in place of junk like 555's, 74-series logic, etc)
2014-12-16T02:56:36 < emeb> that'd work
2014-12-16T02:57:05 < upgrdman> one of my coworkered wants to commission what amounts to an LED blinker, but with a customer pattern..
2014-12-16T02:57:24 < emeb> give him an arduino :)
2014-12-16T02:57:27 < upgrdman> and i don't feel like learning a 8bit uc
2014-12-16T02:57:35 < ds2> MSP430
2014-12-16T02:57:39 < upgrdman> emeb: he's dumb. and he wants 20+ of them
2014-12-16T02:57:56 < upgrdman> ds2: what that be much cheaper than $0.57 each?
2014-12-16T02:58:43 < dongs> what exactly is the target use?>
2014-12-16T02:59:35 < ds2> upgrdman: they claim yes
2014-12-16T03:00:06 < upgrdman> dongs: he wants some blinken lights for his rc planes. but he wants a specific pattern.
2014-12-16T03:00:19 < upgrdman> and he's willing to pay for something custom.
2014-12-16T03:00:27 < upgrdman> more money than brains, etc :)
2014-12-16T03:01:29 < dongs> upgrdman: stm8 is a possiblity, b ut price-wise it wont be much different than that f0/whatever.
2014-12-16T03:01:44 < upgrdman> k. i'll stick with the $0.57 stm32f0 then.
2014-12-16T03:02:01 < upgrdman> just wanted to make sure i wasn't overlooking some $0.10 part or whatever
2014-12-16T03:02:55 < emeb> upgrdman: where you getting those for 57c?
2014-12-16T03:03:11 < upgrdman> err 0.58 actually
2014-12-16T03:03:12 < upgrdman> http://www.futureelectronics.com/en/technologies/semiconductors/microcontrollers/32-bit/Pages/3038310-STM32F030F4P6.aspx?IM=0
2014-12-16T03:03:42 < dongs> great
2014-12-16T03:03:51 < upgrdman> ?
2014-12-16T03:03:51 < emeb> interesting that they're so much cheaper that Mouser
2014-12-16T03:04:08 < upgrdman> ya. it's like mouser qty 10k price
2014-12-16T03:04:18 < upgrdman> but with a min order of 20 on FE
2014-12-16T03:07:03 < GargantuaSauce_> i dont think a vendor being cheaper than mouser is that big a deal
2014-12-16T03:07:13 < GargantuaSauce_> bar is pretty low there
2014-12-16T03:07:36 < upgrdman> ya
2014-12-16T03:07:53 < upgrdman> and would it be worth it to chinese to clone a $0.60 uc?
2014-12-16T03:08:07 < upgrdman> (e.g. FE selling fakes?)
2014-12-16T03:08:17 < dongs> lol plz dude
2014-12-16T03:09:04 < upgrdman> any idea why this SMD cap is so big?  http://www.futureelectronics.com/en/technologies/passives/capacitors/ceramic-capacitors/multilayer-ceramic-capacitors/Pages/2129807-CC1812KKX7R9BB474.aspx?IM=0
2014-12-16T03:09:20 < dongs> 1) 50V
2014-12-16T03:09:20 < emeb> 50V
2014-12-16T03:09:23 < upgrdman> dongs: ? it's worth faking?
2014-12-16T03:09:35 < dongs> upgrdman: no of course not, and thats normal-ish price for that shit
2014-12-16T03:09:41 < upgrdman> i have some 1210 50V 2.2uF mlcc's
2014-12-16T03:09:43 < dongs> we're paying something like 20c for stm8 in that tssop
2014-12-16T03:09:52 < upgrdman> o ok
2014-12-16T03:09:56 < dongs> upgrdman: 2) X7R
2014-12-16T03:10:12 < emeb> which is a better dielectric
2014-12-16T03:10:26 < emeb> more temp stable, less cap sag w/ voltage
2014-12-16T03:10:29 < upgrdman> isnt x7r one of the cheap/shit dielectics? i think c0g etc were the good ones?
2014-12-16T03:10:38 < emeb> x7r is good
2014-12-16T03:10:40 < dongs> you arent gonna get 0.47uF in C0G
2014-12-16T03:10:41 < upgrdman> o ok
2014-12-16T03:10:49 < gxti> x7r is the best you can get for values that large. c0g/np0 is only for tiny values (< 1nF)
2014-12-16T03:10:49 < emeb> y5* is worse
2014-12-16T03:11:02 < dongs> there'es X5, Y5 i think?
2014-12-16T03:11:10 < ds2> who makes a C0G 0.47uF?!
2014-12-16T03:11:21 < gxti> it would be the size of an xbox.
2014-12-16T03:11:25 < emeb> haha
2014-12-16T03:11:26 < dongs> kemet does
2014-12-16T03:11:30 < emeb> XBOXR
2014-12-16T03:11:31 < dongs> C2220C474J5GACTU
2014-12-16T03:11:37 < dongs> its like $5/ea
2014-12-16T03:11:38 < dongs> lulz
2014-12-16T03:11:54 < gxti> i'm surprised it even exists
2014-12-16T03:12:01 < dongs> Capacitor Case Style: 2220 [5650 Metric]
2014-12-16T03:12:03 < gxti> although really 470n isn't that big
2014-12-16T03:12:04 < dongs> also xbox huge
2014-12-16T03:12:06 < ds2> that is handy to know incase I need long time intervals
2014-12-16T03:12:06 < emeb> maybe used by crazy RF dudes
2014-12-16T03:12:17 < dongs> emeb, what aboute traces leading to that
2014-12-16T03:12:19 < gxti> 47u c0g would be impressive
2014-12-16T03:12:55 < emeb> dongs: ya - huge traces suggest not in the RF path
2014-12-16T03:13:13 < gxti> anyway, c0g > x7 > x5 > y5
2014-12-16T03:13:13 < emeb> high-power amp transistor bypass though?
2014-12-16T03:13:32 < emeb> for high voltage, wide temp
2014-12-16T03:13:47 < gxti> and for anything other than c0g there's a huge derating with applied voltage, sometimes -80% especially for the Y ones
2014-12-16T03:13:55 < emeb> yep
2014-12-16T03:14:08 < gxti> you often have to go digging for spec sheets, it's not in the datasheet
2014-12-16T03:14:37 < gxti> if you can find it. i won't buy caps where i can't find a derating chart in cases where it matters...
2014-12-16T03:15:21 < ds2> the derating is for net DC only, isn't it?
2014-12-16T03:15:44 < gxti> i believe so yes
2014-12-16T03:15:58 < emeb> I have a board where I spec'd some MLCCs for an LDO bypass and they dropped too low
2014-12-16T03:16:05 < emeb> LDO started oscillating
2014-12-16T03:16:24 < emeb> Put in an electrolytic of same value - fine.
2014-12-16T03:16:26 < ds2> use LDOs that are unconditionally stable ;)
2014-12-16T03:16:39 < ds2> then hide from purchasing
2014-12-16T03:16:46 < gxti> it's more likely that it didn't like low ESR caps than anything in particular about the value
2014-12-16T03:17:33 < emeb> maybe. haven't looked at it in a while
2014-12-16T03:17:47 < gxti> could be both of course
2014-12-16T03:17:56 < emeb> by that logic I could put a resistor in series to see...
2014-12-16T03:19:04 < emeb> going to try some 50V rated MLCC before redoing the layout though
2014-12-16T03:19:33 < upgrdman> why could too low of an ESR cause instability?
2014-12-16T03:20:20 < emeb> depends on the way the control loop is designed
2014-12-16T03:20:35 < emeb> "Poles on the right side of the plane"
2014-12-16T03:20:52 < gxti> i know practically nothing about stability theory so i'd suggest googling it
2014-12-16T03:21:01 < gxti> https://www.google.com/search?q=ldo+low+esr
2014-12-16T03:21:06 < gxti> some of those look relevant
2014-12-16T03:21:29 < ds2> LDOs are picky about every little thing
2014-12-16T03:21:42 < ds2> too much esr, too little, too much cap, too little cap
2014-12-16T03:22:17 < GargantuaSauce_> think it's because of parasitic inductance
2014-12-16T03:22:31 < GargantuaSauce_> the resistance damps what would otherwise be a nice LC tank
2014-12-16T03:44:01 < upgrdman> did not expect this on a .edu domain: http://art.yale.edu/image_columns/0006/6307/1398947035114.jpg
2014-12-16T03:44:36 < emeb> it's art!

2014-12-16T04:26:51 < kakeman> let's push that 10cm 10cm form to it's limits once again
2014-12-16T04:27:34 < decimad> So hrmm, I don't quite understand how to talk to the phy registers. Is a write with address and everything to MACMIIAR an order for the mac to do whatever I wrote?
2014-12-16T04:27:47 < zyp> yes
2014-12-16T04:29:02 < decimad> Okay thank you... they didn't write it anywhere (or it's my eyes...) so...
2014-12-16T04:31:51 < zyp> http://cgit.jvnv.net/laks_demo/tree/main.cpp?h=ethernet#n63 <- here's what I wrote for talking to phy registers some time
2014-12-16T04:32:25 < gxti> reminds me, i need to come up with something that doesn't just spin until it finishes
2014-12-16T04:32:54 < gxti> there are no interrupts for that unfortunately
2014-12-16T04:33:09 < gxti> but i don't really care how long it takes, as long as it doesn't just spin there and block everything else... so just check it from systick or something
2014-12-16T04:49:30 < kakeman> how gladly texas send samples?
2014-12-16T04:50:50 < qyx_> lets generate 24.576MHz clock
2014-12-16T04:51:22 < kakeman> why :|
2014-12-16T04:51:45 < qyx_> just for fun
2014-12-16T04:52:08 < kakeman> mad
2014-12-16T04:52:08 < qyx_> F401 in a 48pin package doesn't have MCLK available for i2s
2014-12-16T04:52:49 < kakeman> what you doing qyx_?
2014-12-16T04:53:04 < qyx_> science stuff
2014-12-16T04:55:40 < kakeman> cool stuff?
2014-12-16T05:09:16 < qyx_> maybe, hf sdr
2014-12-16T05:09:27 < qyx_> hm, i will run it from MCO at 24MHz
2014-12-16T05:09:51 < qyx_> which gives me 187.5kHz sampling rate

2014-12-16T07:19:32 < gnomad> Hmm, "really uncomforatble dildo" seems like a description that could apply to anything that isn't specifically a dildo...
2014-12-16T07:19:49 < gnomad> also, I just like saying the word "dildo"

2014-12-16T07:34:52 < qyx_> ok, i need to get VDDA from 5V usb
2014-12-16T07:35:16 < qyx_> fb + cap + fb + cap + inductor + cap might be usable?
2014-12-16T07:35:48 < qyx_> or it may insert some instability to other things?
2014-12-16T07:36:25 < qyx_> i mean multipole pi lowpass filter
2014-12-16T07:37:22 < qyx_> or i could be totally wrong, whats better in that case
2014-12-16T07:37:47 < dongs> usb is already gonna be <= 5V
2014-12-16T07:37:55 < dongs> adding 2fb and inductor will drop it to like 4.5V

2014-12-16T07:56:03 < qyx_> stolen idea
2014-12-16T07:56:12 < emeb_mac> qyx_: did you see this? http://ebrombaugh.studionebula.com/radio/hfrx/index.html
2014-12-16T07:56:32 < qyx_> wut, no
2014-12-16T07:56:41 < qyx_> another one to steal
2014-12-16T07:57:20 < emeb_mac> driving the differential I/Q right into the 16-bit SDADC on an F373
2014-12-16T07:57:35 < qyx_> did it work?
2014-12-16T07:57:38 < emeb_mac> yes
2014-12-16T07:57:41 < qyx_> i  mean the whole thing
2014-12-16T07:57:41 < emeb_mac> works great
2014-12-16T07:57:45 < emeb_mac> yep
2014-12-16T07:58:23 < emeb_mac> only one problem - QSM has strong images at multiples of the sample freq.
2014-12-16T07:58:34 < qyx_> hm, different topology though
2014-12-16T07:58:39 < qyx_> you are using 1:4 mixers
2014-12-16T07:59:55 < emeb_mac> it's not that different
2014-12-16T08:00:25 < qyx_> was single stage amp enough?
2014-12-16T08:00:39 < qyx_> ir did you insert something in front of F3x
2014-12-16T08:00:40 < emeb_mac> yes - it's got a lot of gain.
2014-12-16T08:00:54 < emeb_mac> the SDADCs have a PGA in the path too
2014-12-16T08:01:11 < qyx_> ah, you have gain of 100 here
2014-12-16T08:01:59 < qyx_> i will see how it works with 24bit audio adc
2014-12-16T08:02:31 < emeb_mac> cool
2014-12-16T08:02:42 < qyx_> although i am expecting problem at sampling freq in the middele
2014-12-16T08:02:51 < qyx_> because of hpf in the audio adcs
2014-12-16T08:02:52 < emeb_mac> advice - get yourself some lowpass or bandpass filters out in front of the QSM
2014-12-16T08:03:22 < qyx_> did you ac couple it to sdadcs?
2014-12-16T08:03:26 < emeb_mac> I was picking up FM stations @ 80-100MHz
2014-12-16T08:03:35 < emeb_mac> when tuning in the AM band
2014-12-16T08:03:49 < emeb_mac> I DC coupled into the SDADC
2014-12-16T08:04:28 < qyx_> i will probably need to offset the LO a bit and sample only single sideband :S
2014-12-16T08:04:51 < qyx_> to go outside the highpass
2014-12-16T08:05:06 < emeb_mac> ya - my DSP has that capability
2014-12-16T08:05:13 < emeb_mac> just BFO
2014-12-16T08:05:42 < qyx_> ok, at least someone verified it can really work \o/
2014-12-16T08:06:35 < emeb_mac> nothing magic about it - softrock has been doing this for years
2014-12-16T08:07:09 < qyx_> how did your nalog mux behave on higher freqs?
2014-12-16T08:07:29 < qyx_> is it possible to go at ~40MHz?
2014-12-16T08:07:42 < qyx_> with 160MHz from the sixxx synth
2014-12-16T08:07:51 < emeb_mac> I've run it up that high, but there's not a lot of content there to receive.
2014-12-16T08:08:00 < emeb_mac> so it's hard to say.
2014-12-16T08:08:18 < qyx_> there should be something around 40 and 27 (cb)
2014-12-16T08:08:19 < qyx_> will try
2014-12-16T08:08:21 < emeb_mac> should test with a signal generator
2014-12-16T08:08:33 < qyx_> this cdce part can go to 210MHz
2014-12-16T08:10:44 < emeb_mac> looks nice
2014-12-16T08:10:54 < emeb_mac> just don't turn on the SSC. :)
2014-12-16T08:11:14 < qyx_> spread spectrum thing?
2014-12-16T08:11:28 < emeb_mac> yeah
2014-12-16T08:11:29 < qyx_> yep, i noticed it
2014-12-16T08:13:32 < qyx_> anyway, thanks
2014-12-16T08:15:56 < emeb_mac> sure - good luck.

2014-12-16T11:55:05 < varesa> but yeah, I found that out
2014-12-16T11:55:22 < zyp> itm is using swo as an uart, while semihosting triggers a breakpoint which passes control to the debugger
2014-12-16T11:55:50 < zyp> actually, itm shouldn't affect interrupt latency, since it doesn't preempt interrupts
2014-12-16T11:55:58 < varesa> yeah I figured it does something with the debugger that stops "normal" operation since it blocks/delays interrupts
2014-12-16T11:56:04 < zyp> but semihosting does, since it halts the cpu entirely
2014-12-16T11:57:24 < varesa> do all three of those work through SWO?

2014-12-16T15:20:52 < Laurenceb> so SPAD goes off/on when a photon hits, so they could number of triggered SPADs in the array versus time

2014-12-16T15:43:25 < dongs> and like 2 out of 1000 will get ROP locked (if I notice)
2014-12-16T15:43:39 < trepidaciousMBR> hm, weird
2014-12-16T15:45:24 < dongs> anyway. i duno whihc tool does it over swd. I'd imagine st visual programmer will do it.

2014-12-16T15:45:47 < dongs> 'stvp' on ST's site.
2014-12-16T15:47:13 < rewolff1> Eagle has "multiple sheets" if you buy it. Not sure if that "counts" as hierarchical.
2014-12-16T15:47:28 < dongs> heh
2014-12-16T15:47:29 < dongs> not at all.
2014-12-16T15:47:50 < dongs> shit like duplicating a schematic block
2014-12-16T15:48:39 < rewolff1> Well if you "reference" a "subschematic" block, what should happen with the board if you change the subschematic.
2014-12-16T15:49:17 < rewolff1> To prevent that, eagle makes lots-of-copies of everything, so a library component is more or less "imported into the schematic-and-board" at the moment you load it from the library.
2014-12-16T15:49:27 < rewolff1> It's a way-of-working, which you may or may not like.
2014-12-16T15:49:34 < rewolff1> Looks like you don't like it. Fine.

AHB1 is fast enough, I set the divider to the 168MHz version. Phy address seems to be 1 by hardware. What else is there to check?
2014-12-16T17:41:39 < decimad> I'd like to see the clock on the scope, but the line is not routed to the headers :(

2014-12-16T17:54:43 < scrts_w> it's tqfp afaik :)
2014-12-16T17:54:45 < decimad> now that I set the busy bit, I do get a transfer on the mac side... it's just 1's though...
2014-12-16T17:55:06 < scrts_w> also, this PHY works without any settings on MDIO bus
2014-12-16T17:55:19 < scrts_w> it should work straight away after you plug in the cable

2014-12-16T17:55:52 < scrts_w> you should read the phy only to check what speed it negotiated to
2014-12-16T17:55:58 < scrts_w> if that's interested at all
2014-12-16T17:56:18 < kakeman> what kind of stuff happens in MDIO?
2014-12-16T17:56:22 < scrts_w> also the read should only occour on interrupt, that's why that pin is there
2014-12-16T17:56:41 < decimad> scrts_w: this board does not connect the interrupt line.
2014-12-16T17:56:51 < scrts_w> you can read what speed link the PHY is negotiated to, some status bits, etc
2014-12-16T17:56:58 < scrts_w> you can also write to it forcing link speed, etc
2014-12-16T17:57:06 < scrts_w> that's bad
2014-12-16T17:57:08 < decimad> yes, currently I'm trying to read the vendor id ;)
2014-12-16T17:57:20 < scrts_w> you'll have to poll the status of the link then...
2014-12-16T17:57:25 < decimad> of course
2014-12-16T17:57:39 < scrts_w> otherwise you will send the data when the cable is not connected :))) or try to receive the data
2014-12-16T17:57:52 < scrts_w> interrupt is a must from ethernet phy :)
2014-12-16T17:57:55 < decimad> But first I need to get MDIO working ;) MDIO has Pullup, so if I only get 1's the phy didnt respond

2014-12-16T20:33:31 < zyp> do you have any debug freeze settings set?
2014-12-16T20:33:43 < zyp> if not, the DMA should continue to fill even if the cpu is halted
2014-12-16T20:35:06 < mitrax> zyp: hmm i haven't set any particular settings, i'm using openocd btw
2014-12-16T20:35:54 < zyp> what DMA mode are you running?
2014-12-16T20:39:12 < mitrax> i'm using stm32cube's HAL_UART_Receive_DMA(), in normal mode (i.e non circular for now)
2014-12-16T20:39:56 < mitrax> not sure if that's the 'mode' you were refering to
2014-12-16T20:42:16 < zyp> you know what dongs would say?

2014-12-16T21:11:15 < PaulFertser> Isn't it a real issue that most microcontroller programmers aren't really sane or professional, and hence vendors just have to prepare libraries to appeal to them, thus inevitably producing shitty results?
2014-12-16T21:11:56 < BrainDamage> isn't the same argument extended to the myriad of programming languages and libraries for desktops and servers?
2014-12-16T21:12:02 < BrainDamage> eg php
2014-12-16T21:12:50 < PaulFertser> No vendor's going to prepare two distinct libraries, one for your average embedded programmer, and one for "pros".
2014-12-16T21:15:46 < Steffanx> some vendors do admit their lib was a rush job :P

2014-12-16T23:46:11 < pulsar> varesa: in that case you have release and debug build configuration
2014-12-16T23:46:27 < pulsar> varesa: chances are your debugging profile uses a different build configuration than your project is set to.
2014-12-16T23:47:54 < pulsar> varesa:  and apocalypse is what i call ecplise. same as with scarepoint instead of sharepoint. sorry ;)
2014-12-16T23:48:12 < varesa> oh ;)
2014-12-16T23:49:14 < pulsar> debug configurations -> main -> Build configuration vs. project tree -> right click -> build configuration
2014-12-16T23:49:26 < pulsar> they shoudl either match or debug configuration should be set to "use workspace settings"
2014-12-16T23:51:52 < varesa> pulsar: both are set to Debug
2014-12-16T23:52:30 < pulsar> no idea then. we talked already about the debug plugins being buggy themselves and requiring an update?

2014-12-16T23:55:39 < varesa> decimad: atleast the Zylin CDT and GNU ARM eclipse
2014-12-16T23:56:04 < varesa> + I think GDB hardware debugging or something along those lines
2014-12-16T23:57:19 < pulsar> varesa: let me know when you find out. i have run into that issue with being stuck in the debugger without any means to continue the execution a couple of times. solved by updating the gnu arm eclipse plugins usually and/or reinstalling apocalypse.
2014-12-16T23:57:55 < pulsar> varesa: i have also got the debugger to work with netbeans. not as mature (featurewise) as eclipse, but perhaps it is the difference between "works" and "does not work" for you.

2014-12-17T00:24:26 < mitrax> zyp: remember my dma stream interrupt problem from earlier? turns out that if i break the program, then send data to the UART while execution is frozen, then resume, only the stream M0AR register (base address where data will be read) gets updated, the DMA_LISR / DMA_HISR signal no event, and new data after resume don't trigger the interrupt either
2014-12-17T00:25:07 < mitrax> could it be openocd messing things up?
2014-12-17T00:28:29 < mitrax> err actually no i didn't check HISR/LISR yet hold on
2014-12-17T00:37:41 < mitrax> yeah ... HISR/LISR are 0 when resuming and they stay that way although new data are sent on the uart rx line

2014-12-17T04:10:05 < dongs> or just use wolframalpha???

2014-12-17T05:45:40 < upgrdman> reading up on digital filters and control theory. lots of related stuff, none of which i know. transforms (fourier, laplace, z), fir/iir, etc. is this kind of stuff usually taught in a class? what would it be called. need to find some video lectures or textbooks.
2014-12-17T05:49:50 < emeb_mac> of course it's taught in classes

2014-12-17T05:53:24 < emeb_mac> starts out with the basics & covers a lot, including "tricks" that pros use to simplify stuff.
2014-12-17T05:53:39 < dongs> hardcover
2014-12-17T05:53:42 < dongs> more like hardcore
2014-12-17T05:54:02 < emeb_mac> you can probably find it on scribd or something equiv
2014-12-17T05:54:11 < upgrdman> i love hardcovers
2014-12-17T05:55:49 < dongs> kindle DRM + "you dont actually own it" edition is still 76 bucks

2014-12-17T07:06:22 < englishman> pretty much the same except the microstrip is made into a ring with 360 degrees electrical length at resonant frequency
2014-12-17T07:06:35 < englishman> then coupled with another microstrip to load
2014-12-17T07:07:46 < decimad> we're not talking about dong's microstrip
2014-12-17T07:08:39 < englishman> R2COM what are you working on these days

2014-12-17T07:09:51 < englishman> rf is pretty fun
2014-12-17T07:10:28 < englishman> lots of maths
2014-12-17T07:10:44 < decimad> the only problem with rf is, the people developing it don't need it, because they spend their time in dark rooms
2014-12-17T07:11:05 < englishman> this was textbook for this course http://libgen.org/book/index.php?md5=53b65fb687d04417aa2d723da607b411

2014-12-17T07:19:09 < PaulFertser> karlp: what's wrong with the current license? I thought it's LGPL so should be fine for everybody?
2014-12-17T07:19:35 < PaulFertser> Well, LGPL is tricky for embedded, you need to allow the end user to relink against a new version...
2014-12-17T07:20:57 < dongs> PaulFertser: openocd docs sucks. my friend spent hours trying to figure out how to make stm32l0 flash/debug with it
2014-12-17T07:21:04 < dongs> apaprently sample .cfgs are shit too
2014-12-17T07:21:17 < dongs> something about them trying to enable jtag for m0 stuff which only has swd etc.
2014-12-17T07:21:41 < PaulFertser> dongs: no, sample cfgs are fine, also, the doc is big, no arguing here, but it doesn't suck as in it explains everything properly.
2014-12-17T07:21:50 < dongs> k hes just dumb then
2014-12-17T07:22:02 < PaulFertser> dongs: what specific issue did he have? Can you get him to report it so it can get fixed upstream please?
2014-12-17T07:22:12 < decimad> so if I ever use LGPL in a closed source thing, I'd basically need to integrate a programmer somehow?

2014-12-17T07:23:27 < PaulFertser> decimad: afaict, basically, you need to allow the end user to use another version of the same library, by whatever means.
2014-12-17T07:23:29 < decimad> or 'loader' whatever... or do reachable swd pins suffice?

2014-12-17T07:24:42 < PaulFertser> dongs: l0 config was contributed by the ST guys and was undertested, apparently, so it ended up a bit broken (not for the usual stlink+l0 case, but for some other cases). It's getting fixed now.
2014-12-17T07:29:04 < PaulFertser> decimad: reachable swd pins + object files to faciliate linking. Provided the headers contents from the library are non-copyrightable (i.e. do not contain any non-trivial or important code).

2014-12-17T07:55:34 < emeb_mac> why HeNe - wouldn't semiconductor laser work?
2014-12-17T07:56:03 < GargantuaSauce_> needs the beam to come out both ends
2014-12-17T07:56:16 < GargantuaSauce_> maybe a dpss laser would work
2014-12-17T07:56:20 < emeb_mac> so you'd have to modify the tube
2014-12-17T07:56:38 < GargantuaSauce_> it'd just be one of my many fuckin' around projects to learn stuff

2014-12-17T08:01:16 < qyx_> huh 5mW is 14" long?
2014-12-17T08:01:52 < GargantuaSauce_> yeah they are not particularly miniaturizable
2014-12-17T08:01:58 < emeb_mac> voltage depends on length
2014-12-17T08:02:06 < upgrdman> how many mW is a typical pocket laser pointer?

2014-12-17T08:02:58 < qyx_> i would say laser cutters if they were few kW
2014-12-17T08:03:09 < emeb_mac> not such high power
2014-12-17T08:03:09 < GargantuaSauce_> probably lab equipment and educational uses

2014-12-17T12:23:31 < ReadError> dumb question (start of many..)
2014-12-17T12:24:07 < ReadError> EXTI basically maps an interrupt to a GPIO and NVIC handles the actual interrupt on the uC ?

2014-12-17T12:34:09 < trepidaciousMBR> I'm sure someone can answer better, but I think that's right. NVIC handles all interrupts, including those from EXTI. EXTI gives you interrupts on GPIO "events".
2014-12-17T12:34:51 < ReadError> ok so i was on the right train of thought

2014-12-17T16:30:23 < PeterM> Laurenceb: rewolff1: much inductor so henries such railsamaze.
2014-12-17T16:31:35 < PeterM> i count 8
2014-12-17T16:32:00 < rewolff1> Yes, New raspberry has like three, this one has quite a lot more.
2014-12-17T16:32:56 < rewolff1> (my first count had 5, but I've found two more (one less than PeterM) on second count....)
2014-12-17T16:33:27 < PeterM> up near the 3,5mm(?) connector
2014-12-17T16:34:03 < rewolff1> Nope the second one on the bottom near the DDR.
2014-12-17T16:34:09 < PeterM> ahh
2014-12-17T16:34:18 < PeterM> thats a shedload of inductors
2014-12-17T16:35:48 < rewolff1> Hey. Is there  a mic between TV out and Audio out?
2014-12-17T16:38:01 < PeterM> it is possible, i cant imagine what else it would be, but "j8" isnt really helping
2014-12-17T16:40:06 < rewolff1> Where I bought it, the "spec sheet" says: Sound Input:Mic
2014-12-17T16:40:06 < rewolff1> so I'd say it's a mic.
2014-12-17T16:41:04 < PeterM> mm...

2014-12-17T16:43:19 < rewolff1> There are two. One CSI one DSI flex connectors.
2014-12-17T16:43:28 < PeterM> yeah, camera and lcd
2014-12-17T16:44:01 < rewolff1> They copied a few things they shouldn't have copied from the 'pi: mostly the big yellow video out connector.
2014-12-17T16:44:19 < PeterM> oh... thats an sd card slot? i thought it was a retarded shielding can
2014-12-17T16:44:25 < PeterM> what a shit place to put it

2014-12-17T20:57:14 < emeryth> why the hell would an stm32 output pin die from driving a rs485 transceiver? happend to me for a second time
2014-12-17T20:57:50 < emeryth> now the pin outputs at 100mV instead of 3.3V
2014-12-17T21:02:51 < emeryth> too much current sourced by the pin?
2014-12-17T21:03:38 < zyp> sounds unlikely
2014-12-17T21:03:48 < Taxman> so the lower mosfet is all low impedance now?
2014-12-17T21:07:53 < emeryth> the pin is still switching as intended, but at 100mV peak to peak
2014-12-17T21:08:41 < karlp> this is the tx pin?!
2014-12-17T21:09:01 < karlp> I've blown up 485 transcievers, but not th epin on the stm32

2014-12-17T21:18:14 < Taxman> does to current consumption increase when the pin is set high?
2014-12-17T21:20:13 < emeryth> when I connected that input to high with a multimeter it shows 25mA, that doesn't seem right
2014-12-17T21:27:32 < emeryth> yeah, looks like the transceiver is damaged, it's got a pretty low resistance to ground and vcc

2014-12-17T21:40:29 < 7JTABSOAK> zyp: I was just about to implement isr handling in your spirit, but I'm having an issue. How to place isr-pointers in the table without instancing the default implementation again and again?
2014-12-17T21:40:33 -!- 7JTABSOAK is now known as decimad
2014-12-17T21:44:52 < zyp> default implementation?
2014-12-17T21:45:30 < decimad> zyp: template< isr_ids id > void handler() { for(;;); } or something
2014-12-17T21:45:42 < zyp> don't do that
2014-12-17T21:45:54 < zyp> it'll defeat the purpose
2014-12-17T21:46:24 < zyp> the unspecialized template function should be left undefined on purpose
2014-12-17T21:46:45 < zyp> make a separate symbol for the default handler
2014-12-17T21:46:57 < decimad> Then what to put into the vector table?
2014-12-17T21:47:08 < zyp> preferably without C++ mangling, since you need to use it as a weakref alias
2014-12-17T21:47:37 < decimad> If I put  &handler<SomeInterrupt> in there it will be undefined reference for almost everything i suppose?
2014-12-17T21:47:52 < zyp> http://cgit.jvnv.net/laks/tree/interrupt/interrupt.cpp <- look at lines 21-88
2014-12-17T21:48:14 < decimad> oh, one still needs extensions
2014-12-17T21:48:17 < zyp> it'll provide weak symbols for all handlers, which are aliases for unused_interrupt
2014-12-17T21:48:54 < decimad> I remembered it being so elegant that one doensn't need compiler extensions^^
2014-12-17T21:49:10 < zyp> yeah, it's pretty much exactly the same as you'd do in plain C, the only purpose of the templates is to add error checking of the names
2014-12-17T21:50:14 < decimad> zyp: you can't specify the weak alias on the template itself, right?
2014-12-17T21:50:38 < zyp> no, you have to make a specialization

2014-12-17T21:50:50 < decimad> damn, that had saved the hassle
2014-12-17T21:50:55 < gxti> interesting
2014-12-17T21:51:55 < zyp> most of this stuff is stuff that the linker deals with, and you can't really do much about it without attributes
2014-12-17T21:53:58 < decimad> zyp: well, if it weren't for the unused stuff it would work out of the box... but a gazillion of loop functions obviously it out of question. The next best thing would be if one could specify the weak attribute on the unimplemented template...

2014-12-17T21:54:54 < gxti> unimplemented templates don't exist, so they can't have attributes :p
2014-12-17T21:55:08 < zyp> yeah
2014-12-17T21:55:38 < gxti> it's the same pattern as the C version, in that you define all the interrupt handlers but weakly so any other definition wins. it just happens to use templates.
2014-12-17T21:56:37 < gxti> there isn't really any more concise way to do it.
2014-12-17T21:58:50 < zyp> apart from putting the interrupt table in ram and populating it during runtime
2014-12-17T21:59:23 < zyp> (with a fixed four-entry table for stack, reset, nmi and hardfault vectors)
2014-12-17T22:03:20 < decimad> The compiler at least doesn't complain about
2014-12-17T22:03:21 < decimad> template< interrupts::isr_ids id >
2014-12-17T22:03:21 < decimad> void interrupt_handler() __attribute__ ((weak, alias ("unused_interrupt")));
2014-12-17T22:06:41 < zyp> no, but I don't think you can get away with that
2014-12-17T22:07:14 < zyp> the trick is how we're exploiting the name mangling, and I think specialized template functions are mangled differently
2014-12-17T22:08:02 < gxti> i can make hypotheses about how that works but it would be pointless because i don't actually use c++
2014-12-17T22:08:11 < gxti> i would assume it would have to be, though
2014-12-17T22:15:55 < decimad> it links well too
2014-12-17T22:19:55 < decimad> zyp try it, it seems to work... can remove the whole list of instanciations
2014-12-17T22:19:59 < zyp> but does the weakrefs override right?
2014-12-17T22:20:10 < decimad> oh, let's try!

2014-12-17T22:22:47 < decimad> hrmmm, I better learn it now... how can I inspect the table at the command line?
2014-12-17T22:22:55 < decimad> I mean inside the image
2014-12-17T22:23:09 < zyp> that didn't work at all
2014-12-17T22:23:34 < decimad> bad link?
2014-12-17T22:24:09 < zyp> no, it compiled/linked just fine, but the table is useless
2014-12-17T22:24:12 < zyp> ref. http://paste.jvnv.net/view/Skirh
2014-12-17T22:25:27 < zyp> actually, it's sane except that unused vectors for some reason point to 0 instead of the default handler
2014-12-17T22:26:12 < decimad> I would consider this a compiler error then?
2014-12-17T22:27:45 < zyp> might be
2014-12-17T22:28:07 < decimad> I mean if they allow it to compile with weak ref at template declaration level (they needn't to obviously), then it must work... strange
2014-12-17T22:29:22 < zyp> this shouldn't even have anything to do with the weak part, just the alias part
2014-12-17T22:30:49 < decimad> unsed_interrupt is extern "C"? I don't know how to look at the table inside my image :( Cannot test with the normal interrupts, since I let them be the way ChibiOS and the startup code likes them
2014-12-17T22:31:29 < zyp> use objdump
2014-12-17T22:31:41 < zyp> objdump -d -j .vectors foo.elf
2014-12-17T22:31:52 < decimad> thank you a bunch
2014-12-17T22:31:59 < zyp> if you have a .vectors-section in your linker script like I do
2014-12-17T22:33:25 < decimad> Yes, there is one in the chibios-port linker script
2014-12-17T22:33:45 < decimad> that's how the table is placed there as well
2014-12-17T22:34:58 < decimad> zyp: btw, can I copy the enum with credits?
2014-12-17T22:36:03 < zyp> credits? for that?
2014-12-17T22:36:19 < decimad> zyp: well, it was work.
2014-12-17T22:36:24 < zyp> it's a list of interrupt names as listed in the F1 RM
2014-12-17T22:36:38 < zyp> I even think I cut&pasted it from there
2014-12-17T22:36:39 < decimad> I take copying seriously ;)
2014-12-17T22:37:55 < gxti> as a rule of thumb, anything where if you had to rewrite it it would come out exactly the same, there's no point in giving credit
2014-12-17T22:38:22 < zyp> yeah

2014-12-17T22:39:35 < zyp> well, to answer your question, the code is bsd-licensed
2014-12-17T22:54:53 < decimad> I consider this a bug. If you leave out the weak stuff it mentions unresolved externals, if you add it it links but contains garbage...

2014-12-18T05:38:09 < emeb_mac> sounds complicated

2014-12-18T06:47:03 < englishman> i was lookin at rigol DSA1030-PA-TG3
2014-12-18T06:47:09 < englishman> 3GHz with tracking gen for $4k
2014-12-18T06:48:14 < englishman> ya maybe it was that one
2014-12-18T06:48:23 < englishman> o ya
2014-12-18T06:48:45 < englishman> the "A" model only difference is 10Hz RBW eh, i didnt see any other differences?
2014-12-18T06:49:08 < englishman> ~$1k option
2014-12-18T06:50:07 < englishman> isnt 100Hz rbw already pretty good
2014-12-18T06:50:17 < englishman> could it be software feature anyway?
2014-12-18T06:51:31 < englishman> at $5500 could start looking at 6G stuff
2014-12-18T06:52:10 < englishman> isnt that getting into agilent fieldfox territory
2014-12-18T06:53:30 < englishman> anything decent in 6G?
2014-12-18T06:54:00 < englishman> anywhere near that price anyway
2014-12-18T06:54:02 < englishman> ya
2014-12-18T06:54:23 < englishman> depends on how innovative im feeling

2014-12-18T07:00:02 < englishman> whats in the $600 measurement and demodulation option, i dont see a description anywhere
2014-12-18T07:01:28 < englishman> am/fm demod and some bandwidth cursors
2014-12-18T07:03:50 < emeb_mac> demods seem fun but are rarely used
2014-12-18T07:04:24 < englishman> hmm 815 has vswr addon for $500, software only
2014-12-18T07:04:55 < englishman> doesnt include $650 coupler

2014-12-18T09:16:27 < ReadError> you can also setup OpenVPN server on the synology
2014-12-18T09:16:44 < ReadError> and it would be the same as connecting from inside the network
2014-12-18T09:17:40 < qyx_> also like they say on the forum, good luck with public samba access
2014-12-18T09:18:58 < qyx_> if the synology has ssh server, you can use scp/sftp
2014-12-18T09:19:06 < qyx_> aha
2014-12-18T09:19:34 < qyx_> if you are using win, you have two options if nothing changed - samba and webdav
2014-12-18T09:19:40 < qyx_> one is worse than the other

2014-12-18T18:51:34 < trepidaciousMBR> Anyone know what's meant to happen when I enabled readout protection by setting RDP in OPTCR? It seems to have a tendency to just hang the processor, until I power cycle. The protection still gets activated, but I'd really like to do it without having to power cycle, so I can check it's worked afterwards.
2014-12-18T18:53:48 < karlp> huh, that jeelabs dudes earliest demos are things like fading the led attached to the power supply of his lpc810 by modulating the power consumption.
2014-12-18T18:53:54 < karlp> how... obvious
2014-12-18T18:54:12 < englishman> from RM... Note: If the read protection is set while the debugger is still connected through JTAG/SWD, apply

2014-12-19T00:37:48 < karlp> emeb: any recommended synth software for linux? just want to be able to use a midi keyboard and get plinky plonks, doesn't need to be for serious musics, just more than "amidi -d -p HW:2,0,0" and pressing buttons
2014-12-19T00:38:51 < zyp> I think I've heard the name rosegarden
2014-12-19T00:39:08 < karlp> hehe, qsynth got it to work

2014-12-19T00:44:25 < emeb> I think rosegarden is a notation app...
2014-12-19T00:45:13 < zyp> might be, I just know it's a midi app, not exactly what role it has
2014-12-19T00:45:39 < ds2> what do people still use MIDI for thesedays?
2014-12-19T00:46:22 < mitrax> when using DMA to receive data from one of the uart you're still supposed to watch for noise/frame/overrun errors right?
2014-12-19T00:47:41 < emeb> ds2: MIDI is still very heavily used in music production.
2014-12-19T00:47:44 < karlp> I got rosegarden to record keytaps from this f4 disco "keyboard" but I can't get it to play back.  but I'm happy this code works at least :)
2014-12-19T00:48:25 < emeb> karlp: making a USB MIDI controller?

2014-12-19T00:48:42 < karlp> not me, no :)

2014-12-19T00:49:28 < emeb> could be interesting
2014-12-19T00:49:51 < mitrax> i'm asking because i realize that when debugging if i hit a breakpoint the uart status register signals an overrun when there's incoming data (which seems perfectly normal), but in STM32Cube's shitty uart lib there's nothing that take into account the status register when using DMA, the uart error interrupt is not enabled.... so the overrun error flag is signaled, and the dma transfer complete
2014-12-19T00:49:51 < mitrax> interrupt never triggers
2014-12-19T00:49:53 < emeb> I've been working on a USB MIDI -> control voltage processor for a while
2014-12-19T00:50:19 < emeb> works as either host or device, so you can hook a USB MIDI controller box to it, or hook it to a PC.

2014-12-19T01:51:51 < karlp> that didn't take long :)
2014-12-19T01:52:02 < karlp> what was it, this morning? you decided you needed to make your own?
2014-12-19T01:52:10 < emeb> :)
2014-12-19T01:52:26 < karlp> is that just lan8720 to 0.1" headers for (R)MII?
2014-12-19T01:52:31 < emeb> yep
2014-12-19T01:52:53 < emeb> flywires to an stm32f4 disco for testing
2014-12-19T01:53:02 < karlp> looks pro
2014-12-19T01:53:11 < karlp> I like how you get all the silk pretty :)
2014-12-19T01:53:48 < emeb> got a couple vias punching thru silk - could be prettier
2014-12-19T01:54:12 < karlp> why does everythign start with 3?
2014-12-19T01:54:37 < emeb> cause I copied the ckt from a larger schematic - this part was on pg3
2014-12-19T01:55:01 < emeb> if this works then that proves the other schematic and I'll build it.
2014-12-19T01:55:36 < emeb> I can oshpark & test this for < $20
2014-12-19T01:55:48 < emeb> the other one will be more like $75 to fab
2014-12-19T02:02:24 < zyp> so, why did you end up not buying the waveshare one?
2014-12-19T02:03:01 < zyp> or is this a different phy?
2014-12-19T02:03:09 < emeb> right
2014-12-19T02:03:26 < emeb> waveshare no longer makes the lan8720 one AFAICT
2014-12-19T02:03:44 < zyp> no availability either?
2014-12-19T02:04:05 < zyp> also, why must it be 8720?
2014-12-19T02:04:25 < zyp> isn't RMII RMII?
2014-12-19T02:04:27 < emeb> Doesn't _have_ to be, but that's what I was planning to use on the other board.
2014-12-19T02:04:47 < emeb> so I already had the schematic drawn up
2014-12-19T02:05:25 < emeb> All the ST eval boards us an old NatSemi MII PHY so I didn't want to use that
2014-12-19T02:05:50 < emeb> chews up too much I/O
2014-12-19T02:05:53 < ds2> is MII the same as the old AUI stuff?
2014-12-19T02:05:54 < zyp> iirc the waveshare phy that came with my kit (dp-something) is all ready to use and needs no mdio commands to initialize
2014-12-19T02:05:58 < zyp> no
2014-12-19T02:06:05 < zyp> AUI is 10mbe
2014-12-19T02:06:10 < zyp> MII is 100mbe
2014-12-19T02:06:16 < ds2> oh
2014-12-19T02:06:45 < karlp> hrm, you can use mii in 10meg mode though right?
2014-12-19T02:06:52 < zyp> yes, of course
2014-12-19T02:06:55 < ds2> is there anther name for the AUI stuff?
2014-12-19T02:07:12 < zyp> not that I know
2014-12-19T02:07:17 < zyp> http://en.wikipedia.org/wiki/Attachment_Unit_Interface
2014-12-19T02:07:50 < ds2> so much for wiring up a DB15 to a dev board... :/

2014-12-19T02:08:15 < emeb> where does rmii fit?
2014-12-19T02:08:17 < zyp> no, xgmii
2014-12-19T02:08:22 < zyp> rmii is reduced-mii
2014-12-19T02:08:30 < zyp> there's an rgmii too

2014-12-19T02:09:18 < zyp> mii is four lines at 25 Mb/s, rmii is two at 50
2014-12-19T02:09:18 < ds2> doesn't rgmii just do DDR?
2014-12-19T02:09:27 < ds2> oh rmii not rgmii, n/m
2014-12-19T02:09:29 < zyp> not sure about gmii/rgmii
2014-12-19T02:10:04 < zyp> according to wikipedia you're right, rgmii is ddr
2014-12-19T02:10:26 < zyp> but then again, ddr is a doubling of the data rate, just without doubling the clock rate
2014-12-19T02:11:10 < ds2> different problems for debugging
2014-12-19T02:11:59 < emeb> looks like I was wrong - waveshare still has those lan8720 modules.
2014-12-19T02:12:05 < emeb> http://www.wvshare.com/product/LAN8720-ETH-Board.htm
2014-12-19T02:12:35 < emeb> a lot cheaper than I can build it for too of course
2014-12-19T02:12:37 < zyp> isn't that what you linked to the other day?
2014-12-19T02:12:43 < emeb> yeah
2014-12-19T02:13:01 < emeb> but when I looked for it in the store it didn't show up
2014-12-19T02:13:13 < zyp> isn't that the store?
2014-12-19T02:13:18 < emeb> is now
2014-12-19T02:13:25 < emeb> I was looking at a different pg IIRC
2014-12-19T02:13:35 < zyp> pretty sure you linked exactly that
2014-12-19T02:13:43 < emeb> brainfart then
2014-12-19T02:14:14 < zyp> so that's why I was surprised that you suddenly decided to do your own
2014-12-19T02:14:37 < emeb> brainfarts are always surprising. :)
2014-12-19T02:15:36 < emeb> seems that one needs external clk
2014-12-19T02:15:52 < zyp> I see an oscillator on the bottom
2014-12-19T02:16:05 < zyp> and the other waveshare phy board certainly has it's own clock
2014-12-19T02:16:33 < emeb> ah - back side of board. Yep
2014-12-19T02:16:48 < emeb> wonder if that's an osc or xtal
2014-12-19T02:17:31 < emeb> schematic says osc.
2014-12-19T02:17:43 < emeb> wonder what the advantage of that is vs xtal?
2014-12-19T02:17:55 < emeb> since the chip is supposed to handle xtal.
2014-12-19T02:18:13 < zyp> 50mhz units tend to be full oscillators, no?
2014-12-19T02:18:57 < emeb> generally when you go > 20-30MHz then it needs to be overtone
2014-12-19T02:19:04 < emeb> which is fiddly to do well
2014-12-19T02:19:20 < zyp> yeah, I remembered something like that
2014-12-19T02:21:39 < zyp> maybe the oscillator were cheaper than a crystal appropriate for the chip
2014-12-19T02:22:08 < zyp> or maybe they just went «this is what worked on the other phy board we made»
2014-12-19T02:24:59 < decimad> zyp: activating any of the rx pins as alternate mode ETH (11) makes me run into the unexpected exception handler, even though I have all the faults mapped on special functions.... I'm also having a hard time finding out which interrupt causes this, because nvic register states none as active
2014-12-19T02:25:08 < dongs> alienate mode
2014-12-19T02:29:12 < karlp> hrm, maybe I should get one of those wvshare boards too.
2014-12-19T02:30:09 < dongs> you should
2014-12-19T02:30:10 < dongs> they're great
2014-12-19T02:31:12 < upgrdman> well that was dumb. i just replaced a failed GFCI (RCD) outlet on what i later found out was a live circuit.
2014-12-19T02:31:28 < upgrdman> i distinctly touched each wire (individually) and didn't feel anything. lol.
2014-12-19T02:31:50 < upgrdman> but got a little shock at the very end. must have draped a finger between live and neutral.
2014-12-19T02:31:55 < zyp> decimad, check IPSR
2014-12-19T02:32:12 < zyp> IPSR will indicate current handler
2014-12-19T02:32:57 < emeb> what's the best way to get waveshare? direct from them or thru a distrib?

2014-12-19T02:36:39 < karlp> hrm, do I want the "port" board or the "open" board.
2014-12-19T02:36:48 < karlp> I guess open is better if I plan on getting more waveshare periphs
2014-12-19T02:40:09 < Steffanx> they have an ebay shop too emeb, could save you a few bucks on shipping costs.
2014-12-19T02:40:16 < Steffanx> but china ...
2014-12-19T02:40:55 < dongs> < upgrdman> but got a little shock at the very end. must have derped
2014-12-19T02:40:57 < dongs> ftfy
2014-12-19T02:41:03 < upgrdman> ya
2014-12-19T02:41:40 < upgrdman> wonder why it was just a little shock. felt like the kind of shock you might get when plugging in a usb cable

2014-12-19T03:34:29 < emeb> ok - lan module and F407 disco board purchased.
2014-12-19T03:34:55 < emeb> looks like they hike the prices on the ebay store by ~25% to cover shipping
2014-12-19T03:38:49 < Steffanx> Yeah, but i think it's still lower than directly from their shop, when you only need a signle module

2014-12-19T03:44:35 < karlp> emeb: so you're going with the lan8720 at 50Mhz with fly wires to th an f4 disco, rmii (less wires) instead of the dp8xxx module they have that is 25Mhz but mii so more wires?
2014-12-19T03:45:00 < emeb> karlp: I got the interface board for the f407 disco
2014-12-19T03:45:11 < emeb> has a socket for the ethernet board
2014-12-19T03:46:03 < emeb> but yeah - rmii for fewer wires - gives me more I/O on the application I'm designing
2014-12-19T03:53:09 < upgrdman> delicious  http://i.imgur.com/2dzlN85.gif
2014-12-19T03:53:16 < karlp> damnit, I can't figure out how to get the periodic pc sampling on DWT

2014-12-19T03:56:14 < emeb> well - now to sit back and wait to see how long it takes waveshare to deliver.
2014-12-19T03:56:30 < emeb> still faster than oshpark + building it myself probably.

2014-12-19T05:27:36 < upgrdman> anyone here been shocked by 230/240V?
2014-12-19T05:27:43 < dongs> no, lets try on y ou first
2014-12-19T05:27:54 < upgrdman> maybe i just got lucky, but the 120v shock i got didn't even feel that strong
2014-12-19T05:28:09 < upgrdman> of course, it was just across a finger, not across my chest...
2014-12-19T05:28:42 < upgrdman> i was more corned about the time i shocked myself with a chain of 9V batteries in series :) that hurt.
2014-12-19T05:28:58 < upgrdman> i think it was 10 or 12 9V's in series.
2014-12-19T05:29:45 < qyx_> 230V reminds me
2014-12-19T05:29:58 < qyx_> should i bother doing PFC at ~300W?
2014-12-19T05:29:59 < BrainDamage> i've been shocked multiple times by 230V
2014-12-19T05:30:11 < BrainDamage> the longest time lasted ~10s
2014-12-19T05:30:13 < upgrdman> BrainDamage: did it hurt, or just a strong tingle?
2014-12-19T05:30:31 < BrainDamage> mixed
2014-12-19T05:31:14 < BrainDamage> qyx_: there's actually regulations for that, and iirc that's near the treshold case
2014-12-19T05:31:37 < BrainDamage> so go check
2014-12-19T05:32:16 < qyx_> nah, stupid AC
2014-12-19T05:32:25 < upgrdman> i've never noticed anything about PF in my elec bills. do elec companies get bitchey if your PF gets far from 1.0?
2014-12-19T05:32:59 < BrainDamage> they won't bitch for home users, but if you plan to sell, there's regulations
2014-12-19T05:33:12 < upgrdman> o ok
2014-12-19T05:33:48 < dongs> qyx_: EN61000-3-2
2014-12-19T05:34:48 < upgrdman> does thunderbolt -> usb hub exist?
2014-12-19T05:34:55 < upgrdman> fucking MBPs with only two usb ports :(
2014-12-19T05:34:57 < dongs> probably
2014-12-19T05:35:02 < dongs> its just pcie
2014-12-19T05:35:16 < dongs> you should be able to break it out into a bunch of usb3.0 ports
2014-12-19T05:35:20 < dongs> nice, earthquake
2014-12-19T05:35:26 < upgrdman> big?
2014-12-19T05:35:30 < dongs> nope
2014-12-19T05:35:31 < dongs> something shaked
2014-12-19T05:35:37 < upgrdman> fat person fell?
2014-12-19T05:35:39 < qyx_> ok, i will call it professional equipment
2014-12-19T05:35:45 < qyx_> so doesnt apply
2014-12-19T05:36:32 < qyx_> wait what, it doesnt apply for rated power *greater* than 1kW?
2014-12-19T05:36:34 < dongs> qyx, you can only exclude it if its > 1kw
2014-12-19T05:36:38 < dongs> right
2014-12-19T05:36:45 < upgrdman> anyone know of a usb hub that plugs direct into a usb port? like no cable, but super compact/slim that it just fans out some ports?
2014-12-19T05:37:18 < dongs> http://www.jma.go.jp/en/quake/20141219123628453-191234.html
2014-12-19T05:37:24 < dongs> that shit was so small nobody even cared
2014-12-19T05:38:08 < upgrdman> speaking of .jp, what's a prefecture? it is like a state?
2014-12-19T05:38:33 < dongs> yeah
2014-12-19T05:39:02 < upgrdman> do people take pride in being from their prefecture, or is it just a way to split up the country?
2014-12-19T05:39:29 < upgrdman> i mean, like are some prefectures looked upon like "rednecks" etc.
2014-12-19T05:39:45 < dongs> japs hate everyone, even each other
2014-12-19T05:39:50 < dongs> er, even themselves
2014-12-19T05:39:52 < upgrdman> lol srsly?
2014-12-19T05:39:57 < dongs> so i dont think state lines make any difference

2014-12-19T05:45:37 < dongs> they fucking cancelled that hilarious new movie
2014-12-19T05:45:40 < dongs> that i wanted to watch
2014-12-19T05:46:05 < emeb_mac> they pulled "Team America..." from a few years back too. :D
2014-12-19T05:46:30 < emeb_mac> any movie that makes fun of N.K.
2014-12-19T05:47:10 < emeb_mac> theory is it's a marketing ploy - after a few weeks they'll release it to fanfare...

2014-12-19T07:14:29 < qyx_> is it floor?
2014-12-19T07:18:51 < upgrdman> i think so
2014-12-19T07:22:03 < emeb_mac> just sawdust
2014-12-19T07:23:02 < upgrdman> ya, not conductive, but still dumb
2014-12-19T07:24:53 < qyx_> outlets on the floor are also dumb
2014-12-19T07:25:19 < emeb_mac> no argument there
2014-12-19T07:29:15 < ds2> what's wrong with outlets on the floor?
2014-12-19T07:29:48 < upgrdman> water, dust, etc
2014-12-19T07:29:53 < upgrdman> gravity...
2014-12-19T07:30:16 < ds2> guess it depends on where... not much of a problem in shops
2014-12-19T07:31:06 < ds2> you prefer them on the ceiling?
2014-12-19T07:33:28 < upgrdman> just not mm's from the floor
2014-12-19T07:33:49 < upgrdman> >200mm from the floor is fine, no?
2014-12-19T07:36:09 < qyx_> yep, we have them usually 300-400mm from the floor
2014-12-19T07:36:16 < qyx_> mainly because of water
2014-12-19T07:37:39 < decimad> Hrmmm, shouldn't the mac MMC counters be running without any other traffic, f.e. each time the rx led blinks? I assume that, but maybe it's not so
2014-12-19T07:38:48 < decimad> Also I'm wondering ... http://pastebin.com/s1LyL23d ... they're delaying after each write. But why the read + another write there surrounding the 1ms sleep?

2014-12-20T07:59:14 < gxti> it's a complexity tradeoff
2014-12-20T07:59:50 < gxti> much simpler to use fixed buffers for dma and copy stuff into and out of pbufs
2014-12-20T08:00:17 < gxti> i still don't quite have zero-copy rx working, but it's due to allocator shenanigans

2014-12-20T08:03:26 < decimad2_> gxti: well it works for me so far, I embed custom pbufs in the rx dma descriptors data area and on complete frames I can walk the dma list and chain  the pbufs for handoff... the custom free function adds the pbufs back into the pool of available pbufs for dma descriptors
2014-12-20T08:03:52 < gxti> that works. i was going the opposite approach, and handing regular pbufs to dma

LwIp will "free" the pbufs unconditionally, if it is part of its normal pool, I don't get notified when new pbufs are available. So would have to poll until I get memory. In my approach the free function will be notified and can either resupply a dma descriptor in need instantly or add it back to the pool.
2014-12-20T08:25:28 < gxti> i put all the allocator shenanigans into a housekeeping function that gets called in several places. doing it after a frame is received (or fails due to no free buffer), and after a packet is processed (which is where stuff gets freed anyway), should be sufficient
2014-12-20T08:26:06 < gxti> and if you only have exactly enough buffers to deal with your traffic then you will fall over if something decides to hold onto a buffer
2014-12-20T08:26:43 < decimad2_> that must not happen anyways, right? I mean memory is limited

2014-12-20T08:29:01 < gxti> again, the buffers themselves flow in exactly the same way under both implementations
2014-12-20T08:29:15 < gxti> not sure which is "better"
2014-12-20T08:29:25 < decimad2_> Yes, in the end it's just buffers flying circles
2014-12-20T08:31:10 < decimad2_> But if there's no good reason to use custom buffers, I shouldn't waste the space for function pointers and stuff... I will revisit that decision for usre.
2014-12-20T08:31:40 < decimad2_> not that those 4 bytes will make the difference... but I like sleak stuff
2014-12-20T08:33:17 < decimad2_> If sleak means that I mean to remember it means ;)

2014-12-20T13:23:12 < jpa-> how so?
2014-12-20T13:23:24 < jpa-> pretty much every comment points it out as a fail
2014-12-20T13:23:43 < jpa-> should they have a giant "FAIL!!! REMEMBER TO LAUGH!!" on top of the article just in case the reader is dumb?
2014-12-20T13:24:15 < jpa-> i wonder if the creator of that monster meant it to be a joke on his brother
2014-12-20T13:27:13 < gnomad> that's a pretty expensive joke...
2014-12-20T13:27:34 < _Sync_> ye
2014-12-20T13:27:36 < jpa-> yeah - but some people have money
2014-12-20T13:27:48 < jpa-> it would be way too expensive for the purpose anyway
2014-12-20T13:28:18 < _Sync_> yeah
2014-12-20T13:28:22 < _Sync_> and then it has no storage at all
2014-12-20T13:28:38 < _Sync_> buy 5 6/8T disks and have moar
2014-12-20T13:29:11 < gnomad> even if you run raidz2
2014-12-20T13:30:22 < _Sync_> and you still are cheaper
2014-12-20T13:31:08 < qyx_> buy 350 64KB microsd cards
2014-12-20T13:31:10 < qyx_> *GB
2014-12-20T13:32:18 < GargantuaSauce_> hmm, i bet you can get floppy disks by the ton
2014-12-20T13:33:08 < GargantuaSauce_> stick em all on a shelf and make a big cartesian bot to stick them in drives on demand
2014-12-20T13:34:18 < qyx_> you will need to have some advertisements preloaded to fill the gaps in the movies
2014-12-20T13:37:41 < GargantuaSauce_> hmm, with enough in parallel that shouldn't be an issue

2014-12-21T00:48:08 < Laurenceb__> "This configuration is used only when the device operates in master mode. The NSS signal is driven low when the master starts the communication and is kept low until the SPI is disabled"
2014-12-21T00:48:30 < Laurenceb__> what does that mean?!
2014-12-21T00:48:47 < Laurenceb__> you have to disable/reenable to get NSS high?

2014-12-21T01:21:32 < GargantuaSauce_> uh.
2014-12-21T01:21:57 < GargantuaSauce_> why
2014-12-21T01:22:32 < kakeman> IOs that are scattered and barelly enough of them
2014-12-21T01:22:49 < kakeman> another is that I don't need random access all the time
2014-12-21T01:23:14 < kakeman> basically just roll from address X to address Y with some clock
2014-12-21T01:24:25 < kakeman> I just put aux mcu to application area of board
2014-12-21T01:25:07 < kakeman> I think it's best option and inexpensive
2014-12-21T01:26:23 < kakeman> is there any features is modern mcus to access scattered IOs as a single memmory block in one clock cycle?
2014-12-21T01:26:37 < kakeman> some IO mapping stuff?
2014-12-21T01:27:15 < zyp> no
2014-12-21T01:27:39 < kakeman> that would encourage some bad design styles
2014-12-21T01:28:52 < kakeman> I have one solid 8bit block
2014-12-21T01:29:24 < zyp> I'm not sure exactly what you're talking about, but it sounds dumb
2014-12-21T01:29:33 < kakeman> I am
2014-12-21T01:29:47 < zyp> if you need atomic IO, stm32 has BSRR for pins within a single port

2014-12-21T02:02:46 < kakeman> seems to be a standard in 32bit world
2014-12-21T02:06:59 < zyp> yeah
2014-12-21T02:07:11 < zyp> well, even AVR allows you to do atomic IO within a port
2014-12-21T02:07:48 < kakeman> didn't know that 8|
2014-12-21T02:08:03 < zyp> writing to PINx will toggle the output
2014-12-21T02:08:32 < zyp> which means that you can do PINx = (PORTx & mask) ^ value;
2014-12-21T02:10:04 < kakeman> yes
2014-12-21T02:10:07 < kakeman> but
2014-12-21T02:10:43 < kakeman> there is no hw level stuff ?
2014-12-21T02:11:01 < zyp> the writing of PINx doing a toggle is the hw level stuff
2014-12-21T02:11:39 < zyp> it means that only the bits being 1 will be touched, while the others remain unchanged
2014-12-21T02:12:05 < zyp> if you know the former value of the pins you want to change, you don't even need to read PORTx first
2014-12-21T02:12:12 < zyp> i.e. if you only want to toggle a led
2014-12-21T02:13:39 < zyp> there's actually a couple of registers in stm32 that uses the same toggle pattern
2014-12-21T02:14:26 < zyp> namely the state bits in the usb endpoint registers
2014-12-21T02:15:52 < zyp> http://cgit.jvnv.net/laks/tree/usb/f1_usb.h <- it leads to the same kind of xor pattern, see lines 39 and 47

2014-12-21T10:11:28 < decimad2> I consider it rather inconvenient that the tx dma resets all control bits of descriptors, INCLUDING end of ring ...
2014-12-21T10:29:58 < ReadError> so im brain storming here
2014-12-21T10:30:21 < ReadError> I want to make a simple program that counts h/vsync pulses over a period of time
2014-12-21T10:30:27 < ReadError> i could use timer counter
2014-12-21T10:30:37 < ReadError> or external interrupt+counter
2014-12-21T10:31:07 < ReadError> is there any benefit to doing it one way over the other?
2014-12-21T10:31:54 < qyx_> yes, using timer input capture makes 0% cpu usage
2014-12-21T10:32:42 < decimad2> You may be using 0% of the cpu, but's you're blocking the timer 100%!
2014-12-21T10:32:48 < ReadError> so then when my main timer hits 0, I can just pull the capture count out from each h/vsync timer ?
2014-12-21T10:33:02 < qyx_> yes
2014-12-21T10:33:07 < qyx_> it can count o every capture event
2014-12-21T10:33:24 < qyx_> and you can read it anytime
2014-12-21T10:33:28 < ReadError> problem im worried about is scaling, eventually I will need 10 independant timers
2014-12-21T10:33:39 < ReadError> each counting
2014-12-21T10:35:26 < jpa-> why 10?
2014-12-21T10:35:46 < jpa-> but yeah, if you need 10 channels, EXTI is better
2014-12-21T10:35:58 < jpa-> both should easily handle the speed required for hsync
2014-12-21T10:36:03 < ReadError> jpa- its for an analog video diversity system
2014-12-21T10:36:12 < ReadError> with 5 RX inputs
2014-12-21T10:36:26 < ReadError> im using vsync/hsync over a period of time to determine quality
2014-12-21T10:38:57 < qyx_> you could also do it the other way around
2014-12-21T10:39:10 < qyx_> run a timer at a constant rate
2014-12-21T10:39:21 < qyx_> and use input capture to capture all sync pulses
2014-12-21T10:39:29 < qyx_> and then dma them to memory buffer
2014-12-21T10:39:44 < qyx_> you would even have their exact time
2014-12-21T10:40:02 < qyx_> and few more KB of ram usage :X
2014-12-21T10:40:21 < ReadError> im not worried too much about RAM, thats all the uC will be doing
2014-12-21T10:40:48 < qyx_> this would be 500 lines * 25 fps * 16bit for one second
2014-12-21T10:40:56 < qyx_> thats 25KB
2014-12-21T10:41:00 < qyx_> ok, not usable approach
2014-12-21T10:41:28 < ReadError> Im thinking just counting alone will be sufficient
2014-12-21T10:41:42 < ReadError> more vsync/hsync in a period of time, probably a better signal
2014-12-21T10:41:45 < qyx_> use exti then
2014-12-21T10:41:57 < ReadError> I think exti gets me 16 or something
2014-12-21T10:42:01 < ReadError> which should be plenty
2014-12-21T10:43:19 < ReadError> although im not sure how the shared IRQ handlers will play a part
2014-12-21T10:44:01 < ReadError> when it hits the shared one, can I just query what GPIO pin brought it there?
2014-12-21T10:44:59 < qyx_> if you are fast enough and the signal is long enough
2014-12-21T10:45:53 < ReadError> hmm another road block, all these h/vsync pulses should be firing off at the same time
2014-12-21T10:46:01 < ReadError> since theres only 1 video source

2014-12-21T11:32:04 < dongs> At a price of $799, this is definitely not a budget IPS monitor.but it doesn't have budget specs, either. The PB279Q supports a 100% sRGB color gamut with 10-bit color, where most monitors opt for 8-bit or 6-bit+FRC. 10-bit is usually reserved for monitors aimed at professional photographers and graphic designers, so the panel should look even better than the average IPS display, which are known for color quality and viewing angles above and beyond cheaper TN panels.

2014-12-21T17:49:14 < dongs> http://www.artlebedev.com/everything/reflectius/process/ fuck, i wanna make this
2014-12-21T17:53:19 < ABLomas> ;-)
2014-12-21T17:53:27 < GargantuaSauce_> thats pretty interesting
2014-12-21T17:53:31 < Steffanx> whoa, nice :)
2014-12-21T17:53:47 < dongs> i wonder why they didnt take it past concept, im guessing laser light isnt as visible as it would have to be for this to work
2014-12-21T17:53:49 < GargantuaSauce_> and all you need is a bunch of $2 servos
2014-12-21T17:53:53 < dongs> right
2014-12-21T17:53:56 < GargantuaSauce_> you'd need a smoke generator for sure
2014-12-21T17:53:57 < dongs> http://img.artlebedev.com/everything/reflectius/process/reflectius-014.jpg
2014-12-21T17:55:06 < englishman> a use for those cheapass ebay stepper motors
2014-12-21T17:55:35 < GargantuaSauce_> use a 100~200mW green dpss, one of those water atomizers, and a spinning polygonal mirror to multiplex between the digits
2014-12-21T17:55:52 < dongs> tell me more about this multiplex
2014-12-21T17:56:01 < ABLomas> several lasers would help a lot
2014-12-21T17:56:10 < englishman> mirror with several flat facets that spins?
2014-12-21T17:56:25 < dongs> ABLomas: yes, but that loses the "cool" factor
2014-12-21T17:56:28 < dongs> of a single beam
2014-12-21T17:56:29 < GargantuaSauce_> multiple lasers would get pretty expensive if they arent low power shitty ones
2014-12-21T17:56:42 < GargantuaSauce_> and they kind of need to not be in order to be visible
2014-12-21T17:56:44 < englishman> or that steps between set angles time-multiplexed to distribute lazer faster than eye can resolve
2014-12-21T17:56:55 < ABLomas> laser for each vertical axis (8 in total) + dimmer mirror (electrically controlled) = no moving parts, silent and easy
2014-12-21T17:56:55 < GargantuaSauce_> that would be noisy
2014-12-21T17:57:19 < dongs> servos is definitely boring for this tho
2014-12-21T17:57:41 < dongs> galvo/voicecoil would be way cooler
2014-12-21T17:58:07 < GargantuaSauce_> i havent seen one of those with more than like 15 degrees of rang
2014-12-21T17:58:11 < GargantuaSauce_> e
2014-12-21T17:58:40 < GargantuaSauce_> but yes it would definitely be cooler
2014-12-21T17:58:53 < qyx_> you can do it with a magnet mounted on a mirror
2014-12-21T17:58:56 < qyx_> and 3 coils
2014-12-21T17:59:07 < qyx_> theres practically 0 torque needed
2014-12-21T17:59:16 < qyx_> so it should work without feedback
2014-12-21T17:59:45 < GargantuaSauce_> https://www.youtube.com/watch?v=vAyCl4IHIz8 not entirely relevant but i think you'll dig this upgrdman
2014-12-21T18:00:02 < qyx_> even better if a magnet was actually the mirror
2014-12-21T18:00:04 < GargantuaSauce_> may have already spammed it in here i cant remember

2014-12-21T18:03:23 < dongs> hm
2014-12-21T18:03:51 < dongs> qyx, 3 coils and adjusting current in each to make it rotate to given position?
2014-12-21T18:03:59 < qyx_> yep
2014-12-21T18:04:01 < qyx_> or pwm
2014-12-21T18:04:27 < dongs> wonder if that would be stable enough
2014-12-21T18:04:32 < dongs> for it not to jitter up the laser
2014-12-21T18:04:34 < dongs> once its in position
2014-12-21T18:04:52 < qyx_> probably not much if you shake it
2014-12-21T18:04:57 < GargantuaSauce_> think you'd just need one pulse for it to align with the one coil, and then stop applying current
2014-12-21T18:05:12 < dongs> oh, hm
2014-12-21T18:05:39 < qyx_> thats another possibility
2014-12-21T18:05:39 < GargantuaSauce_> basically a really shitty multipole stepper motor
2014-12-21T18:05:43 < qyx_> make it "bistable"
2014-12-21T18:05:48 < qyx_> or multistable
2014-12-21T18:07:15 < emeb> kinda like those magnetic pixels they use on outdoor signs
2014-12-21T18:07:24 < Steffanx> dongs just take one of your displays and play the flash video on the overview page :P
2014-12-21T18:07:37 < emeb> flip between black and fluorescent green...
2014-12-21T18:07:59 < qyx_> yep, they use it on buses here
2014-12-21T18:08:52 < emeb> I think the biggest problem would be getting a constant source of fog to see the beam in
2014-12-21T18:08:52 < dongs> Steffanx: pfft, wheres hte fun in that
2014-12-21T18:09:11 < dongs> heh the overview video definitely uses "servos"
2014-12-21T18:09:20 < dongs> they rotate slowly.
2014-12-21T18:09:55 < emeb> "Damn - my clock is out of fog juice again..."
2014-12-21T18:10:18 < GargantuaSauce_> just water and one of those ultrasonic atomizers would do
2014-12-21T18:10:25 < GargantuaSauce_> would put water everywhere though
2014-12-21T18:10:34 < emeb> need to use distilled
2014-12-21T18:10:58 < emeb> otherwise minerals in the water accumulate everywhere
2014-12-21T18:11:07 < GargantuaSauce_> ah yeah
2014-12-21T18:11:20 < emeb> "Damn - my clock is out of distilled water again..."
2014-12-21T18:11:27 < GargantuaSauce_> hm. could also angle the beam so it's "dragging" on the backing surface
2014-12-21T18:11:32 < GargantuaSauce_> and reflecting diffusel
2014-12-21T18:11:34 < GargantuaSauce_> y
2014-12-21T18:11:58 < GargantuaSauce_> that would be hard to work out for different path lengths for different digits though
2014-12-21T18:12:25 < emeb> ya - point source beam would "run out"
2014-12-21T18:12:29 < emeb> need line source
2014-12-21T18:12:47 < GargantuaSauce_> well if the angle is shallow enough the line can be quite long
2014-12-21T18:12:50 < emeb> like they use in those chop saws
2014-12-21T18:12:55 < GargantuaSauce_> and there is nonzero divergence
2014-12-21T18:13:06 < GargantuaSauce_> but yeah a cylindrical lens would do the trick also

2014-12-21T18:14:09 < GargantuaSauce_> yeah that guy does some wonky stuff
2014-12-21T18:14:49 < GargantuaSauce_> i wanna do the same thing with galvos but you have to deal with the actual mirror inertia instead of just capacitance
2014-12-21T18:15:06 < emeb> yeah - galvo drivers are ugly
2014-12-21T18:15:15 < emeb> high current, lots of feedback

2014-12-21T18:15:32 < GargantuaSauce_> well i have off the shelf galvo drivers and they work well, but the actual control signals are hard too
2014-12-21T18:15:50 < GargantuaSauce_> cant have sharp edges without waiting for it to catch up, etc

2014-12-21T18:20:48 < ReadError> hello my friend
2014-12-21T18:21:04 < ReadError> Is it possible a breakpoint can interfere with an NVIC priority?
2014-12-21T18:21:21 < zyp> interfere how?
2014-12-21T18:21:38 < ReadError> it seems like if I set my breakpoint on the function that calls to send something over UART, when it gets in the function that sends something is blocking
2014-12-21T18:21:45 < ReadError> if i disable the breakpoint, it works fine ;/
2014-12-21T18:22:19 < zyp> uh, what?
2014-12-21T18:22:38 < GargantuaSauce_> isnt that kind of the point of a breakpoint
2014-12-21T18:23:19 < ReadError> well it occurs after the breakpoint
2014-12-21T18:23:30 < ReadError> let me try moving it I guess
2014-12-21T18:24:13 < zyp> singlestepping will also block interrupt handling
2014-12-21T18:24:20 < ReadError> yea thats what im doing
2014-12-21T18:24:24 < ReadError> probably the issue..
2014-12-21T18:24:28 < dongs> ugh
2014-12-21T18:25:20 < zyp> well, consider what would happen if it didn't
2014-12-21T18:25:23 < ReadError> zyp can I raise the priority on debugging so the serial stuff takes precedence ?
2014-12-21T18:25:28 < zyp> no
2014-12-21T18:26:06 < zyp> debugging stops the cpu, you can't have it do anything in the background while stopped

2014-12-21T18:26:44 < zyp> and if singlestepping would process pending interrupts, you'd likely end up in the systick handler every time you stepped
2014-12-21T18:27:14 < jpa-> i think gdb implements single-stepping by line (not stepi but step) by setting breakpoint on next line
2014-12-21T18:27:29 < jpa-> so then it could (and i think will) process interrupts without anyone knowing
2014-12-21T18:27:32 -!- Smd__ is now known as Smd_
2014-12-21T18:27:43 < zyp> jpa-, not by stepping multiple times?
2014-12-21T18:27:53 < jpa-> not sure
2014-12-21T18:28:12 < jpa-> i have got "could not set breakpoint" errors when i've had already the max number
2014-12-21T18:28:20 < jpa-> but not sure if it was 'n' or 's'
2014-12-21T18:28:31 < jpa-> 'n' would be quite slow if it did single stepping
2014-12-21T18:39:08 < ReadError> zyp that was the problem
2014-12-21T18:39:15 < ReadError> i moved the breakpoint until after it, works fine

2014-12-21T19:51:52 < jpa-> a similar problem karlp had on stm32l1:
2014-12-21T19:52:00 < jpa-> 2013-01-22T13:38:52 < karlp> oh, figured out my ADONS problem yesterday.
2014-12-21T19:52:00 < jpa-> 2013-01-22T13:39:18 < karlp> I hadn't properly switched to full speed, so it was running on the MSI at 4Mhz, while the adc always runs off HSI at 16mhz.
2014-12-21T19:52:00 < jpa-> 2013-01-22T13:39:23 < karlp> and HSI hadn't been turned on.
2014-12-21T19:52:33 < zyp> F3 doesn't have MSI
2014-12-21T19:53:18 < zyp> but yeah, I'm probably missing some RCC settings, reading through the RM right now
2014-12-21T19:54:03 < jpa-> yeah, has a special ADC clock path, though
2014-12-21T19:55:34 < zyp> ah, found it
2014-12-21T19:56:14 < zyp> ADC blocks takes two clocks, one for the registers and one for the core clocking
2014-12-21T19:56:33 < zyp> and the second is not being generated
2014-12-21T19:56:48 < zyp> so that explains why register writes still work

2014-12-22T03:46:06 < kakeman> and a girl
2014-12-22T03:47:06 < upgrdman> and the 90's monitor and speakers.
2014-12-22T03:47:18 < kakeman> they even have glowing aura around them
2014-12-22T03:47:34 < kakeman> heavenly
2014-12-22T03:47:34 < upgrdman> and that one of those 90's apple keyboards? lol.
2014-12-22T03:48:24 < upgrdman> wow, this mouse pad is even bigger  http://www.amazon.com/Extra-Large-Super-Mouse-23-6x11-8x0-11/dp/B00ITL9YN6/ref=sr_1_3?ie=UTF8&qid=1419212598&sr=8-3&keywords=large+mouse+pad
2014-12-22T03:48:59 < upgrdman> i think i might get it. mouse pads work as great table covers. one big ass coaster, easy to wash, quiet when you set things on it, etc.
2014-12-22T03:49:33 < kakeman> have you tried how esd matt works as mousepad?
2014-12-22T03:50:09 < upgrdman> i have not. good?
2014-12-22T03:50:48 < kakeman> when you have boards and chips laying around keyboard and mouse
2014-12-22T03:52:48 < kakeman> and lots of money
2014-12-22T03:54:17 < kakeman> but I think it's too soft and mouse stalls
2014-12-22T03:54:27 < kakeman> and you need mousepad then anyway
2014-12-22T03:57:02 < upgrdman> shit, even bigger: http://www.amazon.com/Perixx-DX-1000XXL-Gaming-Mouse-Pad/dp/B00EG7WB8C/ref=sr_1_8?ie=UTF8&qid=1419212598&sr=8-8&keywords=large+mouse+pad

2014-12-22T13:42:31 < karlp> surprise surprise, "main loop" task checking spends vast majority of it's time checking whether it's time to run a task again! hooray for profiling.

2014-12-22T13:43:17 < decimad2__> karlp: so that's that what you should optimize!
2014-12-22T13:43:47 < karlp> nah, it's all working, this was just doing the profiling of working code to check that things were as expected, and that it was doing the right thing.
2014-12-22T13:44:23 < karlp> the addr2line thingy isn't always the most clear though, it's returning the last line of one file, and the line with the closing } of a function in others,
2014-12-22T13:44:35 < karlp> but it's "close enough" to work out where it's spending time.
2014-12-22T13:44:45 < jpa-> did you try openocd's profiling?
2014-12-22T13:46:30 < karlp> I don' tbelieve it's hooked up to the swo pc sampling I'm getting, but that's the eventualy idea
2014-12-22T13:46:55 < jpa-> yeah, does basically the same but slower
2014-12-22T13:47:27 < jpa-> integrates with gprof & other tools, though, which is somewhat nice
2014-12-22T13:48:10 < karlp> yeah, I just want to make the swo->gprof/ctf/?? converter
2014-12-22T13:48:25 < karlp> addr2line | sort | uniq -c | sort is ok, but not really ideal :)
2014-12-22T13:49:05 < jpa-> yeah :)
2014-12-22T13:49:15 < karlp> this is breaking it repeatedly, I'm not even sure the program still runs properly witht he builtin profiling.
2014-12-22T13:49:35 < jpa-> been there done that, though it is very nice than in linux you can make a shitty profiler in 1 line of bash ;)
2014-12-22T13:51:38 < karlp> heh, the oocd builtin profing gives completely different results
2014-12-22T13:52:07 < karlp> mostly seems tot hink it's in interrupt handlers
2014-12-22T13:52:55 < karlp> presumably a sideaffect of how it interrupts the target to get the pc value and resume again
2014-12-22T13:52:57 < jpa-> probably interrupts become pending while it pauses the cpu, reads PC and continues
2014-12-22T13:53:20 < jpa-> i wonder if stlink allows command queuing
2014-12-22T13:54:46 < karlp> no clue, but why bother when you should just use the swo stream for this sort of sampling anyway?
2014-12-22T13:55:05 < jpa-> because i only have stlinkv1 ;)

2014-12-22T16:28:49 < decimad2__> anybody played chinise whispers with checksums?
2014-12-22T16:29:01 < PaulFertser> What's easier: to implement USB host and CDC ACM and then NCM/WBIM/whatever or to simply hook up a GSM/UMTS module via uart and use ppp?
2014-12-22T16:29:28 < lieron> I would say PPP is easier
2014-12-22T16:29:43 < PaulFertser> Way, way easier. Especially given lwIP already implements everything you need for that.
2014-12-22T16:30:06 < lieron> I'm getting closer. I wasn't seeing replies but think it was because I was debugging. Now I see a PPP message from the module every 3 seconds and lwip replies to it
2014-12-22T16:30:11 < jpa-> though if you need more than GPRS speeds, there are more modules with USB than RS232 
2014-12-22T16:30:17 < karlp> if you have usb, why on earth would you do cdc-acm and then ppp?
2014-12-22T16:30:19 < PaulFertser> IIRC it was fairly straightforward, the only gotcha was using proper AT*99***1# command.
2014-12-22T16:30:23 < lieron> not yet having any data going back and forth, but hopefully soon
2014-12-22T16:30:31 < karlp> there's other clases directly for doing networking you know...
2014-12-22T16:30:40 < PaulFertser> CDC Ethernet, yes
2014-12-22T16:30:53 < PaulFertser> Not all gsm modules implement it, unfortunately.
2014-12-22T16:31:08 < PaulFertser> Also, implementing host side cdc ethernet is not easy either.
2014-12-22T16:32:06 < PaulFertser> karlp: you'll still need cdc acm to send the modem a few commands to activate the channel most likely. Not the case with NCM but I do not think it's less complicated overall.

2014-12-22T17:37:14 < karlp> dongs: are you desparete for the curled over lips on top?
2014-12-22T17:37:44 < dongs> karlp: no im just looking what its called. looks like c-beam, tho on the shit I got they're really curved in
2014-12-22T17:37:50 < abd> jpa-, can DMA runs for ever on specific channel? is  it a problem?
2014-12-22T17:37:55 < dongs> karlp: im just trying to find example of what I used to hookup my dish stuff to a pole
2014-12-22T17:38:18 < jpa-> abd: depends what you are doing - it will go happily overwriting old data you haven't read yet
2014-12-22T17:38:19 < rewolff> jpa: That may give an optimistic value: Suppose some function (at one of deepest levels) does; If (error) printf (...); That would spoil the day (assuming printf uses a lot of stack, which it probably does).
2014-12-22T17:38:50 < jpa-> rewolff: it is true, so have to leave margin and test throughoutly
2014-12-22T17:39:03 < karlp> dongs have you searched for just "wiring channel" ?
2014-12-22T17:39:17 < karlp> that lip is normally there to click the cover plates in isn't it?
2014-12-22T17:39:26 < dongs> karlp: nah this was heavy duty steel shit
2014-12-22T17:39:33 < abd> jpa-, u mean DMA continuously override old byte?
2014-12-22T17:40:35 < karlp> dongs: have a look in the visual catalog on mcmaster carr?
2014-12-22T17:42:02 < dongs> probly be easier to take pics at the office etomrow

2014-12-22T17:42:28 < dongs> almost this, so its probly some jap variation of c-beam

2014-12-22T17:46:06 < karlp> C channel "with return"
2014-12-22T17:47:47 < karlp> or even just "lip channel"
2014-12-22T17:48:09 < decimad2__> holy, "the same" setup would take more .text and way more .bss with freertos and its stm hal usage Oo
2014-12-22T17:48:20 < karlp> http://www.steelmate.co.za/lipchannel.html
2014-12-22T17:48:53 < karlp> looks like local names for that sort of thing though
2014-12-22T17:49:08 < dongs> karlp: lipchannel doens't bend in
2014-12-22T17:49:45 < dongs> that was kinda critical to how the rest of the shit was hooked up because tehre was a pipe mounting bracket that got shoved in tehre and pressed against the C-shaped end
2014-12-22T17:50:30 < dongs> k zzz time
2014-12-22T17:52:01 < PaulFertser> decimad2__: probably LTO will reduce .text considerably. FreeRTOS allocates all of its heap in bss, so no wonder.
2014-12-22T17:52:53 < kakeman> dongs: Lipped C
2014-12-22T17:53:31 < kakeman> lipped c sectionm
2014-12-22T17:54:52 < kakeman> what you innovate dongs?
2014-12-22T17:55:39 < lieron> I'm still stuck with PPP. I get a message "login OK" from the mobile network, but then nothing useful happens after. Any ideas where I can find more info how it should work?
2014-12-22T17:56:04 < jpa-> connect from PC using PPP and see how it works there?
2014-12-22T17:56:31 < lieron> I tried that, just doesn't work at all (Windows)
2014-12-22T18:14:49 < PaulFertser> lieron: try a standard OS, where you can use pppd
2014-12-22T18:17:26 < PaulFertser> lieron: basically, you need +CGDCONT=.., D*99***1#, then wait for CONNECT, then start ppp.
2014-12-22T18:20:17 < lieron> I got that part right (I think).
2014-12-22T18:20:26 < lieron> It's just lwip PPP doesn't seem to connect (or something)
2014-12-22T18:20:39 < lieron> I see a few messages go back and forth and then nothing
2014-12-22T18:42:47 < decimad2__> PaulFertser: Yes, of course I checked both with lto on... though the freertos thing is dysfunctional, i quickly hammered in some lwip calls to get the dependencies... don't think I caught everything

2014-12-22T20:44:01 < jadew> hey
2014-12-22T20:44:10 < Tectu> jadew, this?  https://www.google.ch/search?q=DER-5000&es_sm=122&tbm=isch&tbo=u&source=univ&sa=X&ei=b2aYVI_mHoPsO5H_gMAN&ved=0CCEQsAQ&biw=1920&bih=965
2014-12-22T20:44:15 < Tectu> looks pretty awesome indeed
2014-12-22T20:44:24 < jadew> heh
2014-12-22T20:44:34 < jadew> I guess it's DE-5000
2014-12-22T20:44:42 < jadew> DER EE is the company making them
2014-12-22T20:44:54 < Tectu> interesting, what's the price tag?
2014-12-22T20:45:26 < jadew> I paid $90, delivered with TL-21 - some short leads and TL-something else (kelvin tweezers)
2014-12-22T20:46:31 < jadew> I never used a LCR before, it's amazing the kind of info you get from it is amazing, I wish it had a higher frequency setting tho
2014-12-22T20:46:42 < jadew> pretty good test frequencies btw
2014-12-22T20:47:06 < jadew> 100 Hz, 120 Hz, 1 kHz, 10 kHz and 100 kHz
2014-12-22T20:48:41 < Tectu> DE-6000 Handheld LCR Meter   --->    0.2% Accuracy up to 33% Improvement from discontinued DE-5000
2014-12-22T20:48:50 < Tectu> holy crap, that DE-5000 must have a horrible accuracy
2014-12-22T20:49:46 < jadew> Tectu, up to 33% improvement, means that it had 0.3% accuracy :P
2014-12-22T20:50:01 < jadew> which is not that bad
2014-12-22T20:50:12 < Tectu> I know, was just kidding ;)
2014-12-22T20:50:36 < jadew> seems able to measure resistance down to the milliohm
2014-12-22T20:51:51 < jadew> Tectu, where did you get that info from? the IET site?

2014-12-22T22:43:05 < ossifrage> On stm32 cortex-m0s is bkpt without the debugger attached a nop or a hardfault?
2014-12-22T22:44:08 < zyp> not sure about m0, but on m3/m4 it's a fault unless you have bkpt handler embedded, then it's bkpt
2014-12-22T22:44:32 < zyp> I don't remember which bit that controls it and whether that bit exists on m0
2014-12-22T22:45:00 < ossifrage> the arm docs says it is undefined/implementation dependent
2014-12-22T22:45:06 < zyp> bkpt will only be a nop when you have a nop bkpt-handler that's embedded
2014-12-22T22:45:44 < ossifrage> Hmm, I don't think the cortex-m0 has a bkpt handler
2014-12-22T22:48:36 < karlp> Laurenceb: what do you mean about they stole your logger and repackaged it?
2014-12-22T22:48:47 < karlp> that winchiphead is a fairly old company doing solutions like that
2014-12-22T22:50:30 < zyp> «If both halting debug and the monitor are disabled, a breakpoint debug event escalates to a HardFault and the processor ignores the other debug events.»
2014-12-22T22:50:40 < zyp> that's what the architecture TRM says
2014-12-22T22:51:04 < zyp> «the monitor» refers to the handler
2014-12-22T22:51:44 < zyp> which is apparently controlled by the MON_EN bit in DEMCR
2014-12-22T22:52:40 < ossifrage> «The processor might also produce a HardFault or go in to lockup if a debugger is not attached when a BKPT instruction is executed. See Lockup for more information.»
2014-12-22T22:53:02 < ossifrage> I love the word 'might' in a document like this
2014-12-22T22:53:24 < zyp> where does it say that?
2014-12-22T22:53:43 < ossifrage> http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.dui0497a/BABHCHGB.html
2014-12-22T22:54:21 < zyp> well, it's true, it's what happens if MON_EN is not set
2014-12-22T22:59:39 < zyp> okay, cortex-m0 doesn't have that
2014-12-22T22:59:43 < zyp> so it'll hardfault
2014-12-22T23:01:00 < zyp> as per C1.5 in ARMv6-M TRM
2014-12-22T23:07:01 < ossifrage> zyp, thanks

2014-12-23T01:07:37 < TheSeven> hm, how do I know which of several peripherals on F1 that may use a pin will actually get it if both have their clocks on?
2014-12-23T01:07:37 < TheSeven> is there any way to influence that? e.g. the order in which I enable the peripherals?
2014-12-23T01:09:40 < zyp> yes, check out the remap tables in the reference manual
2014-12-23T01:10:27 < zyp> order of enabling shouldn't matter at all
2014-12-23T01:11:40 < TheSeven> zyp: so how do I tell which peripheral will "win" if multiple want to have a pin?
2014-12-23T01:12:01 < TheSeven> i.e. a uart wants to map a CTS line on top of my ethernet pins, but I don't need CTS, I only need TX/RX

2014-12-23T01:12:19 < ds2> the one wth the strongest transistor?
2014-12-23T01:13:05 < zyp> TheSeven, then you might want to use something other than F4 to save you the headache
2014-12-23T01:13:11 < zyp> that's my usual solution
2014-12-23T01:13:44 < TheSeven> you mean "use F4 instead of F1"?

2014-12-23T03:43:07 < kakeman> I'm watching Lexx
2014-12-23T03:45:20 < upgrdman> is 802.11ac really worth the price? i mean, if g sucks in my area, would ac be better?
2014-12-23T03:47:10 < zyp> no
2014-12-23T03:47:55 < GargantuaSauce_> yes
2014-12-23T03:48:04 < upgrdman> :/
2014-12-23T03:50:28 < zyp> as far as I know, ac is just supposed to give you more capacity through more spectrum usage, so if you're already limited by available spectrum, it probably won't help any
2014-12-23T03:51:25 < zyp> hmm, though, I'm thinking compared to n, not compared to g
2014-12-23T03:52:17 < GargantuaSauce_> ya
2014-12-23T03:52:43 < upgrdman> i might be on n
2014-12-23T03:53:04 < upgrdman> i have an old 2.4/5g router... the kinda that is EITHER 2.4 or 5, not at the same time :(
2014-12-23T03:53:52 < upgrdman> but speaking of bandwidth, if you want to transfer 1Gbps, does that mean you need at least 1GHz of bandwidth?
2014-12-23T03:54:02 < upgrdman> cause that doesn't make sense :)
2014-12-23T03:54:04 < GargantuaSauce_> no
2014-12-23T03:54:11 < zyp> hmm, looks like ac also introduces 256-QAM
2014-12-23T03:54:14 < zyp> upgrdman, no
2014-12-23T03:54:32 < zyp> bitrate is bits per symbol multiplied by symbol rate
2014-12-23T03:54:56 < upgrdman> hmm. would it be 1Gbps needs 1GHz if using binary symbols?
2014-12-23T03:55:20 < zyp> symbol rate is limited by spectrum, as per nyquist, bits per symbol is limited by SNR
2014-12-23T03:56:24 < upgrdman> ya
2014-12-23T03:57:02 < upgrdman> but for OOK, you would need 1GHz for 1Gbps, right?
2014-12-23T03:59:00 < zyp> 500 MHz
2014-12-23T03:59:20 < zyp> remember that nyquist frequency is Fs/2
2014-12-23T03:59:58 < upgrdman> k
2014-12-23T04:00:48 < upgrdman> i dont suppose there is some awesome 802.11ac (or other super fast) router these days that everyone seems like love? like the wap54g was in the 00's.
2014-12-23T04:02:49 < KreAture> Steffanx I took a 30 min stab at the stm32f407 issue I had yesterday and cracke dit, haven't worked on it since last time I mentioned it

2014-12-23T04:34:54 < upgrdman> cool. i was actually looking at that model at frys todays.
2014-12-23T04:35:28 < upgrdman> only reason why i didnt buy is because i often get fucked over on impulse buys :)

2014-12-23T05:45:52 < decimad2_> Hehe, so I always only compiled with optimizations to see the size, I never actually executed it... in fact the compiler optimized my vector table away, so I had to attribute it with "used". Now I'm seeing a build error about the undefined symbol "_port_exit_from_isr"
2014-12-23T05:46:04 < decimad2_> It is nowhere define in a C-Way, but there's
2014-12-23T05:46:07 < decimad2_>   asm volatile ("_port_exit_from_isr:" : : : "memory");
2014-12-23T05:46:27 < decimad2_> Which I guess shall instruct the compiler to place an asm-marker there?
2014-12-23T05:47:33 < decimad2_> It seems in -O3 lto builds this gets swallowed... anybody's got an idea how I could prevent that?
2014-12-23T05:51:39 < decimad2_> Obviously I can remove the asm volatile marker and make it a naked separate function, but thereby I'm violating the license...

2014-12-23T09:43:52 < decimad2> okay, now that might be a good alternative
2014-12-23T09:44:09 < decimad2> in the end os switching is only about getting the threads and timers working again ;)
2014-12-23T09:44:16 < dongs> right
2014-12-23T09:44:18 < decimad2> if you don't rely on any HAL that comes with it
2014-12-23T09:44:27 < dongs> there isnt one wiht rtx
2014-12-23T09:44:36 < dongs> its chibidongs that forces shit on you
2014-12-23T09:44:40 < decimad2> no it doesnt
2014-12-23T09:44:47 < decimad2> that's why I wrote my ethernet driver
2014-12-23T09:44:50 < dongs> ok, "gently suggests"
2014-12-23T09:45:34 < decimad2> I think I got the feeling that chibi is "quicker" or more elegant... but mabye that is not so?
2014-12-23T09:45:48 < decimad2> 192 cycles task switch > 0.4µs on chibi
2014-12-23T09:45:54 < akaWolf> jpa-: well, ok, looks like it works, when I added "-C folder" option
2014-12-23T09:46:05 < dongs> isnt chibios GPL?
2014-12-23T09:46:20 < dongs> that makes it instantly useless
2014-12-23T09:46:24 < decimad2> otoh they say they don't block interrupts (RTX) ...
2014-12-23T09:46:44 < akaWolf> jpa-: but where is stored the project options?
2014-12-23T09:46:45 < decimad2> dongs: chibi is LGPL with extra rules in the release builds
2014-12-23T09:47:14 < akaWolf> jpa-: there is no my option in the kdev4 file..
2014-12-23T09:47:53 < jpa-> akaWolf: it makes a .kdev4 folder
2014-12-23T09:47:55 < jpa-> no idea why
2014-12-23T09:48:15 < akaWolf> jpa-: in the ~ ?
2014-12-23T09:48:31 < jpa-> in the project folder
2014-12-23T09:48:40 < akaWolf> ah ok
2014-12-23T09:49:26 < akaWolf> a little strange, yeah..
2014-12-23T09:51:13 < akaWolf> but can be used, at least
2014-12-23T09:53:37 < akaWolf> jpa-: which one debug launcher should I use?
2014-12-23T09:54:14 < jpa-> no idea, i have always liked text mode gdb better so i use it even when working in an IDE
2014-12-23T09:54:36 < akaWolf> awww
2014-12-23T09:56:43 < akaWolf> looks like it's not possible to debug via KDevelop a bare metal systems
2014-12-23T09:58:27 < jpa-> why not?
2014-12-23T09:58:45 < akaWolf> native debug via KDevelop?
2014-12-23T09:58:54 < jpa-> the "compiled binary launcher" seems to allow you to give gdb binary name and gdb init script
2014-12-23T09:58:58 < jpa-> what more do you need to config?
2014-12-23T09:59:18 < akaWolf> arm version of gdb
2014-12-23T09:59:31 < jpa-> yes, type arm-none-eabi-gdb in the "GDB executable" field
2014-12-23T09:59:46 < jpa-> or if you have a script to start openocd etc, type that into the script field..
2014-12-23T10:00:38 < akaWolf> I have no such filed
2014-12-23T10:00:41 < akaWolf> field*
2014-12-23T10:01:11 < akaWolf> and not even "compiled binary launcher", only "Application launcher"
2014-12-23T10:01:37 < jpa-> http://kapsi.fi/~jpa/stuff/pix/kdevelop_launcher.png
2014-12-23T10:01:42 < jpa-> which version are you using
2014-12-23T10:01:46 < akaWolf> maybe I used too old KDevelop..
2014-12-23T10:02:04 < akaWolf> Version 4.5.2
2014-12-23T10:02:26 < jpa-> i'm using 4.7.0
2014-12-23T10:02:44 < akaWolf> well, ok.
2014-12-23T10:03:35 < jpa-> though i remember trying out kdevelop for bare metal debugging back in 2012 - it worked, but debugging optimized code with gdb is such annoyance that gui was totally useless
2014-12-23T10:04:14 < akaWolf> why are you debug an optimized code?
2014-12-23T10:04:35 < akaWolf> why not debug a non-optimized version first?
2014-12-23T10:05:00 < akaWolf> and optimized version then..
2014-12-23T10:05:07 < jpa-> it was a project with lot of DSP stuff going on, simply unusable without optimizations
2014-12-23T10:05:23 < jpa-> (because i can't slow the rest of the system, some of it analog, down)
2014-12-23T10:06:21 < akaWolf> hm ok
2014-12-23T10:06:56 < jpa-> specifying optimization settings per-file would have helped, but it wasn't such a problem
2014-12-23T10:07:07 < akaWolf> I guess, such situations can occure :)
2014-12-23T10:07:18 < jpa-> i got by, bugs got fixed, still like text mode better
2014-12-23T10:07:24 < akaWolf> arise*
2014-12-23T10:07:58 < akaWolf> but not often
2014-12-23T10:09:05 < akaWolf> kind of taste... in QtC exists a FakeVim mode.
2014-12-23T10:10:53 < akaWolf> irssi, as I thought
2014-12-23T10:11:20 < jpa-> in editors, i do prefer graphical and don't like vim
2014-12-23T10:18:36 < akaWolf> jpa-: I prefer a graphical mode in the debug and edit, since I'm always debugging a "debug" version of binary. bebugger do many works by yourself, such as catching the values of variables, memory, expressions at each step of debugging, I guess, it's a more faster, then type "b ...", then for show value, then "r" again, etc.
2014-12-23T10:20:00 < akaWolf> I'm agree, that I need to know, how it works in gdb, but use it all time...
2014-12-23T10:20:10 < akaWolf> it's not for me :)

2014-12-23T10:28:18 < akaWolf> I'm not find it slow with j-link
2014-12-23T10:29:22 < akaWolf> also in the Keil with stlink it's also was not slow

2014-12-23T11:58:59 < zyp> that's normal crosstalk
2014-12-23T11:59:23 < decimad2> One could set the outputs slower or use the IO compensation cell?

2014-12-23T13:42:54 < ReadError> hm is there a register I can verify which clock is being used?
2014-12-23T13:43:17 < ReadError> this nucleo doesnt have HSE
2014-12-23T13:44:31 < decimad> what does "this nucleo doesn't have HSE" have to do with "Is there a register I can verify which clock is being used?" `?
2014-12-23T13:44:58 < ReadError> decimad well I used the f4 stdperiph files
2014-12-23T13:45:19 < ReadError> and it looks like its trying to setup HSE in system_stm32f4xx.c
2014-12-23T13:45:39 < decimad> which is reasonable for f4 stdperiph files
2014-12-23T13:45:45 < decimad> since f4 has HSE
2014-12-23T13:46:01 < decimad> if there is one connected, and you instruct it to do
2014-12-23T13:46:21 < ReadError> yea but nucleo doesnt have one connected
2014-12-23T13:46:35 < ReadError> I have some 12mhz dip xtals I can put in though
2014-12-23T13:46:48 < decimad> then basically the pll will lever lock in I guess
2014-12-23T13:47:16 < ReadError> basically stuff runs, but when I try to use serial the output is jacked up
2014-12-23T13:47:22 < ReadError> so I suspect its a clock issue
2014-12-23T13:47:49 < decimad> there's the status register that holds the clock switch right in front of core
2014-12-23T13:47:55 < decimad> it won't lie
2014-12-23T13:50:50 < ReadError> CR->HSEON is enabled
2014-12-23T13:50:57 < ReadError> i suspect that might be the issue
2014-12-23T13:51:08 < decimad> What does RCC_CFGR say?
2014-12-23T13:51:47 < decimad> in Bits 3:2
2014-12-23T13:51:47 < ReadError> http://i.snag.gy/KZBRK.jpg
2014-12-23T13:52:31 < ReadError> bit3=1, bit2=0
2014-12-23T13:52:35 < decimad> pll is used as system clock (you could read that up in the reference manual btw)
2014-12-23T13:52:47 < decimad> so then you need to see what clock is input to pll ;)
2014-12-23T13:54:37 < decimad> so bit 22 of rcc_pllcfgr
2014-12-23T13:55:10 < decimad> prolly 0
2014-12-23T13:56:57 < decimad> no it's 1
2014-12-23T13:57:19 < decimad> you're using the external clock, I thought there was none?
2014-12-23T13:57:40 < ReadError> there is a 16mhz one apparently
2014-12-23T13:58:45 < decimad> looking at circuit helps ;)
2014-12-23T13:58:46 < ReadError> so RRC->CFGR is 0x00001000 which is 0x08

2014-12-23T13:59:44 < ReadError> oh sorry, yes, there is no external clock
2014-12-23T13:59:51 < decimad> well,  that seems to be code that tries to detect the current configuration maybe to calculate the clock frequency or something
2014-12-23T13:59:58 < ReadError> there is an internal 16mhz clock
2014-12-23T14:00:33 < decimad> if there is no external clock and you're running on HSE, then your mcu should run at 0 Hz
2014-12-23T14:00:59 < decimad> no need to calculate anything, it's the easy case
2014-12-23T14:01:03 < ReadError> yea, I want to force it to HSI
2014-12-23T14:01:15 < decimad> then use HSI as input for pll
2014-12-23T14:03:16 < ReadError> hmm maybe I can just define USE_HSE_BYPASS
2014-12-23T14:03:29 < decimad> why would you wann run on an internal rc oscillator if you have a way better external one btw?

2014-12-23T14:04:34 < decimad> then how the hell does your mcu run currently? If it is set up for HSE and there is no HSE, it cannot run?
2014-12-23T14:05:03 < ReadError> good question, i guess its falling back to HSI ?
2014-12-23T14:05:37 < decimad> then pll input or master switch would show that I guess...
2014-12-23T14:21:06 < decimad> oh
2014-12-23T14:21:30 < decimad> the HSE will probably come from the external mcu (st link debugger)

2014-12-23T14:57:38 < PaulFertser> Is it possible to reenable lower priority interrupts before exiting a higher-priority handler?

2014-12-23T15:13:23 < PaulFertser> I mean I'm pondering an idea of doing something time-critical in timer ISR, then enabling preemtion by lower priority interrupts, then finishing the task (as only starting is critical finishing should be preemptable), then exiting from the handler.
2014-12-23T15:14:13 < PaulFertser> I understand I can get another small FSM handle the non-critical part outside the ISR, but it's a pain to code in C.

2014-12-23T15:18:24 < decimad> couldn't you change the pc in the exception stack frame to point elsewhere and push the old return and pop it in elsewhere again?
2014-12-23T15:21:06 < decimad> hrmmm, but that is probably not compatible to intercepted multicycle ops...

2014-12-23T15:27:26 < PaulFertser> decimad: too nasty of idea for me, can't easily see a nice implementation, also, I'm already using FreeRTOS in this project.
2014-12-23T15:27:31 < decimad> So you could just drop priority and restore it afterwards

2014-12-23T15:29:57 < decimad> but obviousl you could easily start missing interrupts then...
2014-12-23T15:31:30 < PaulFertser> decimad: changing basepri the described way allows to prevent nesting, but I would like to have nesting.
2014-12-23T15:32:16 < decimad> not basepri
2014-12-23T15:32:31 < decimad> just the serviced isr priority i mean
2014-12-23T15:33:07 < PaulFertser> The thread you linked to was talking basepri.

2014-12-23T15:37:53 < decimad> and the few posts beore
2014-12-23T15:37:56 < decimad> before
2014-12-23T15:41:35 < PaulFertser> He says changing priority on the fly should be possible in non-Thread mode and that it won't work in Thread mode. But normal code runs in Thread (not Handler), and it changes NVIC priorities all right, so I do not see how that can be right.
2014-12-23T15:43:19 < decimad> Well obviously changing the priority of an interrupt that is not currently running will not change the priority of the running code
2014-12-23T15:43:51 -!- BrainDamage [~BrainDama@dynamic-adsl-78-12-249-152.clienti.tiscali.it] has joined ##stm32
2014-12-23T15:44:29 < decimad> Changing BASEPRI affects all interrupt (and thereby even thread code) priorities
2014-12-23T15:45:30 < decimad> But I thought you wanted to catch one single interrupt quick and then calm down... so for that you could change that specific priority the moment you thing you can calm down.
2014-12-23T15:46:25 < PaulFertser> But I want to continue the execution of the handler. Yes, if the priority is changeable on-the-fly, in the middle of the handler, that would be it.
2014-12-23T15:46:40 < decimad> Exactly that's what they're saying there
2014-12-23T15:46:52 < decimad> On v7m that is possible
2014-12-23T15:49:14 < decimad> but other code will then be able to prevent further interrupt processing... so I don't think that's ideal
2014-12-23T15:50:43 < decimad> But it can't get better really, since even the low priority part needs to run at the interval pace of the important stuff... they're always tied...
2014-12-23T16:01:15 < PaulFertser> decimad: ok, thank you, will think about it.

2014-12-24T04:51:24 < decimad2_> smps: Yes, indeed ;)
2014-12-24T04:51:49 < smps> probably some way to load immediate value into register
2014-12-24T04:52:04 < decimad2_> But that register is not referenced inside the loop
2014-12-24T04:52:11 < decimad2_> It just gets loaded
2014-12-24T04:52:15 < decimad2_> again and again
2014-12-24T04:53:05 < decimad2_> Also, r3 contains the same value... it's basically a peripherals base address
2014-12-24T04:53:21 < decimad2_> So it could as well say ld r4, r3

2014-12-24T04:59:04 < decimad2_> I was just pointing out that the compiler does an unnecessary load there for a value that it already has in another register

2014-12-24T09:38:02 < ossifrage> Right now gcc is dead striping the function I'm trying to call
2014-12-24T09:39:44 < ossifrage> Adding ___attribute__((used)) to the C function works, but it seems like that shouldn't be needed.

2014-12-24T09:47:59 < decimad2> ossifrage: I could not find a better solution either
2014-12-24T09:48:48 < ossifrage> Looks like you just need to mark the function as read in the asm modifier list thingie
2014-12-24T09:49:11 < ossifrage>  asm volatile("blah" : : "r"(function));
2014-12-24T09:49:47 < ossifrage> decimad, that at least gets it to compile, need a bunch more stuff to test it
2014-12-24T09:50:02 < decimad2> ossifrage: what's blah there?
2014-12-24T09:50:25 < PaulFertser> The asm code
2014-12-24T09:50:33 < ossifrage> ldr r2, =function\nbx r2\n ...
2014-12-24T09:50:35 < decimad2> So basically the bl function ?
2014-12-24T09:50:53 < decimad2> or call or whatever
2014-12-24T09:51:17 < decimad2> This only happens with link time optimization for me betw
2014-12-24T09:51:31 < ossifrage> I'm using -flto with dead stripping
2014-12-24T09:51:42 < decimad2> And I'm not absolutely sure if 4.9 still shows that behaviour
2014-12-24T09:52:08 < ossifrage> I'm using 4.8.4 launchpad
2014-12-24T09:52:17 < decimad2> have you tried 4.9 yet?
2014-12-24T09:52:29 < dongs> t;ldr
2014-12-24T09:52:29 < ossifrage> Not between now and CES :-)
2014-12-24T09:52:33 < decimad2> Let me give it a go, I'll remove one of the attribute used
2014-12-24T09:52:41 < decimad2> back in a second
2014-12-24T09:52:42 < dongs> CES?
2014-12-24T09:52:59 < ossifrage> demo firedrill without any hardware yet, lucky me
2014-12-24T09:54:02 < ossifrage> dongs, consumer electronics clusterfuck show
2014-12-24T09:54:09 < dongs> yes, i know
2014-12-24T09:54:14 < dongs> what junkz are you demoing there
2014-12-24T09:54:49 < ossifrage> I am not sure why they are bothering, CES is a waste, but...
2014-12-24T09:55:30 < dongs> i took my tv shit to a few trade shows, it  didnt really make much difference, but its niche test/engineering use shit
2014-12-24T09:55:42 < decimad2> no, launchpad 4.9 didnt fix this either
2014-12-24T09:55:46 < dongs> will do again in 2015 since im mkaing some new junk

2014-12-24T13:41:24 < decimad2> well it turns out that under real conditions bitbanding is not so great, yes you're saving the volatile read and modify, but you're bying it for a constant read + constant
2014-12-24T13:43:02 < zyp> bitbanding is a waste of time
2014-12-24T13:43:35 < zyp> it's a microoptimalization, and you're still getting a RMW operation on the bus
2014-12-24T13:44:29 < decimad2> zyp: I'm getting it "for free", so the "micro optimization time cost" is not relevant here
2014-12-24T13:44:43 < zyp> it'd be useful if we had a optimization pass in the compiler that could detect RMW operations and rewrite them to bitband operations where they are useful
2014-12-24T13:45:17 < zyp> because, like you say, it's not always beneficial in the generic case
2014-12-24T13:45:39 < decimad2> yeah, it's actually hard to find places where it helps
2014-12-24T13:45:57 < decimad2> many places you're "waiting" on a bit, so no speed relevance there
2014-12-24T13:46:50 < decimad2> Maybe if the compiler had a pass that tries to "combine" constants it would be good
2014-12-24T13:47:02 < zyp> uh, what?

2014-12-24T13:47:39 < decimad2> Well say if it sees 0x0012324124 and 0x0235235132 lying around, that it uses one and offsets in all references of the other
2014-12-24T13:47:59 < zyp> well, it does
2014-12-24T13:48:39 < zyp> assuming the addrs are all known at compile time
2014-12-24T13:48:41 < decimad2> Hrmmmm, it doesn't seem to do here, on a scale larger than function calls... or I'm missing it... that's also related to the suboptimal code that was generated when I didn't put the registers in a struct
2014-12-24T13:50:45 < decimad2> Well, I'll use ^= for bitbanded
2014-12-24T13:50:59 < decimad2> So one can quickly change ;)

2014-12-24T16:22:20 < decimad2> So I'm running into Hard Faults again, it seems to be an escalated Memory Bus excepition, the BFAR value is states as valid and the faulting address is 5555555D, which seems like a good reason to complain... but the exception stack frame only contains garbage... what could I do from here on? I have not the slightest idea what is causing this
2014-12-24T16:23:23 < qyx_> sometimes stacks are prefilled with 0x55
2014-12-24T16:23:36 < qyx_> wat, is that you with emblocks?
2014-12-24T16:24:12 < Steffanx> he uses chibios.. and chibios does the stack filling thing.
2014-12-24T16:24:22 < Steffanx> (if enabled)
2014-12-24T16:25:30 < decimad2> I have CH_DBG_FILL_THREADS defined to TRUE
2014-12-24T16:26:37 < qyx_> so you accidentally your stack
2014-12-24T16:29:00 < decimad2> I accidentally my stack?
2014-12-24T16:30:01 < qyx_> lack of general interwebs knowledge
2014-12-24T16:30:04 < qyx_> but back on topic again
2014-12-24T16:30:15 < qyx_> this can happen if you access uninitialized local pointer for example
2014-12-24T16:31:37 < decimad2> But if that was the case then why does the stack frame only contain garbage?
2014-12-24T16:37:15 < decimad2> although I guess chibios uses thread stack pointer for user threads?
2014-12-24T16:37:28 < decimad2> and I'm seeing the main stack pointer here
2014-12-24T16:43:30 < dongs> BFAR more like FUBAR
2014-12-24T16:56:45 < decimad2> what is funny is that the main stack pointer points to an address where all words above (ie. bigger address) are 555555
2014-12-24T17:07:01 < decimad2> oh

2014-12-25T00:30:58 < upgrdman> wonder what the ENOB is though.

2014-12-25T01:48:24 < kakeman> can I leave some of output banks of clock buffer fanout ic unpowered as those have individual sources?
2014-12-25T01:48:46 < kakeman> Vcco for any output bank should be less than or equal to Vcc (Vcco ≤ Vcc).
2014-12-25T01:58:41 < zyp> sounds like a bad idea, but that's just my intuition
2014-12-25T02:02:51 < kakeman> yes

2014-12-25T14:52:57 < PaulFertser> decimad2__: yeah, STM32 implementing only the 4 higher bits of priority can be surprising. Also, that nasty subgrouping... I can hardly imagine when it might come useful.

2014-12-25T16:16:55 < Lux> usuually you do a pin change interrupt and count up an integer there
2014-12-25T16:17:35 < Lux> or you could increment the timer using the clock input
2014-12-25T16:17:48 < Lux> dunno the details on how that works

2014-12-25T17:16:35 < dongs> is that trash?
2014-12-25T17:16:45 < qyx_> dongs: you should have at least 300 lux

2014-12-25T20:37:14 < ReadError> now its chugging along at 84MHz
2014-12-25T20:39:27 < qyx_> those are the values i wrote earlier :)
2014-12-25T20:39:40 < qyx_> except 12/16 for pll_m
2014-12-25T20:40:03 < ReadError> yea, only thing that needed to be changed was the 25 -> 12
2014-12-25T20:40:13 < ReadError> which makes sense with the 40.3MHz..

2014-12-25T22:24:53 < kakeman> is it wonderful when session times out while you write a novel in forms

2014-12-26T01:14:24 < kakeman> is there any sense to have differential ref clock input capacity in fun gen

2014-12-26T01:37:55 < jadew> have what?
2014-12-26T01:38:29 < jadew> ah differential
2014-12-26T01:38:54 < jadew> of course not
2014-12-26T01:39:56 < jadew> the ref. clock will be so low freq, it won't matter
2014-12-26T01:40:17 < jadew> and all the clocks that really matter, will be generated very close to the modules using them
2014-12-26T01:40:44 < kakeman> yes
2014-12-26T01:40:46 < jadew> if they're not generated close, they'll have clock recovery circuitry where they're needed
2014-12-26T01:41:44 < jadew> at least that's how I suspect high end wave gens do it
2014-12-26T01:42:39 < jadew> such a design tho, will require everything else to be really nice too
2014-12-26T01:42:47 < jadew> otherwise it won't matter
2014-12-26T01:45:53 < jadew> now that I think about it, they might
2014-12-26T01:46:35 < jadew> my wave gen has 1 GSa/s, so somewhere in there, there's a 1 GSa/s clock
2014-12-26T01:47:21 < jadew> I suppose it could use differential pairs for clock, even for short distances
2014-12-26T01:47:32 < jadew> especially since it has to meet a very tight jitter specification

2014-12-26T14:48:52 < kakeman> what is highest spi speed you have used?
2014-12-26T14:49:02 < karlp> and what ref man are you following that says the f42 and f43 have a different periph set?
2014-12-26T14:49:28 < Tectu> karlp, STM32F series only do 8 and 16-bit SPI afaik
2014-12-26T14:49:52 < Tectu> karlp, and somebody told me that new F42 and F43 have a "dynamic" bit length
2014-12-26T14:49:55 < Tectu> word length*
2014-12-26T14:50:00 < Tectu> transaction length*
2014-12-26T14:50:03 < Tectu> package length*
2014-12-26T14:50:05 < Tectu> ^ pick one
2014-12-26T14:50:30 < karlp> so, you're making shit up again.
2014-12-26T14:51:00 < Tectu> karlp, show me the ref taht says taht STM32F can do anything else but 8- and 16-bit SPI
2014-12-26T14:51:08 < Tectu> that*
2014-12-26T14:51:10 < Tectu> double typo, nice.
2014-12-26T14:51:58 < karlp> did I ever say it didn't? I was questioning your claims about f42 and f43 being different.
2014-12-26T14:52:09 < Tectu> karlp> Tectu: what are you talking about spi limitations?
2014-12-26T14:52:46 < karlp> that was just asking what you meant.
2014-12-26T14:53:13 < karlp> still unconvinced that 8/16bit frames matter :)
2014-12-26T14:53:36 < karlp> decimad: as you can see, "better" is in the eye of the beholder :)
2014-12-26T14:54:00 < karlp> there's esoteric features that a re different in the different parts around, but you need to look for what you're really after
2014-12-26T14:54:12 < Tectu> karlp, yep, you're right, not even F42 and F43 have anythinge lse
2014-12-26T14:54:14 < Tectu> "8- or 16-bit transfer frame format selection"
2014-12-26T14:54:23 < Tectu> karlp, there are many many 9-bit SPI slaves
2014-12-26T14:54:44 < Tectu> starting with some nokia displays
2014-12-26T14:55:14 < Tectu> note that you often use SPI although it is not a real SPI slave but has a anything-but-8-or-16-bit serial interface
2014-12-26T14:55:28 < Tectu> in which case you'll be more than thankful if you have a configurable one
2014-12-26T14:55:53 < qyx_> i would say st doesn't care about nokia displays

2014-12-26T22:47:24 < qyx_> 1?
2014-12-26T22:48:16 < jpa-> does your gcc agree?

2014-12-26T22:50:19 < qyx_> regardless of memset
2014-12-26T22:50:28 < jpa-> after undefined behaviour, anything is allowed to occur, even spankings
2014-12-26T22:50:57 < englishman> Maybe ternary is not performing as you think
2014-12-26T22:51:30 < englishman> I am certainly not c guru

2014-12-26T22:52:55 < zyp> reported what? it's perfectly sane behavior
2014-12-26T22:53:09 < karlp> in what world?
2014-12-26T22:53:10 < jpa-> this madness or "sanity" is what C is :)
2014-12-26T22:53:39 < zyp> the memory area for a bool is only allowed to contain 1 or 0, stuffing anything else there leads to undefined behavior
2014-12-26T22:54:02 < Steffanx> undefined behavior is never sane..
2014-12-26T22:54:28 < zyp> and if x can only be 0 or 1, (x ? 1 : 0) is equivalent to x, which means the compiler is allowed to do that optimization
2014-12-26T22:54:39 < englishman> What happens if you change to ? 5 : 6;
2014-12-26T22:54:54 < jpa-> then it happens to work as expected
2014-12-26T22:55:08 < jpa-> but the compiler would be allowed to optimize it to  6 - x   and break
2014-12-26T22:55:09 < zyp> but it could also happen to print 6-123
2014-12-26T22:55:12 < zyp> yeah
2014-12-26T22:55:27 < qyx_> i hate bool
2014-12-26T22:56:26 < jpa-> now i just hope that no nanopb user will ever forget to initialize a variable, as that would lead to very confusing crashes - but of course i trust all the newbie coders in the world, i wouldn't have wanted to do any defensive coding anyway
2014-12-26T22:59:47  * Tectu wonders if jpa- will ever forget about spankings
2014-12-26T23:01:05 < jpa-> nope, they made a lasting impression

2014-12-26T23:09:11 < jpa-> i guess the best way to think about that is that bool has trap values, like float has signalling NaN etc.

2014-12-27T15:42:11 < jpa-> in general, i don't understand hobbyists who do dev boards for anything
2014-12-27T15:42:32 < jpa-> might as well make the final board, or just use jumper wires for prototypes

2014-12-27T15:43:14 < jpa-> mass produced dev boards make a bit more sense, as there the amount of work is reduced not increased
2014-12-27T15:43:31 < jpa-> Steffanx: but you can keep one bit more in the status register carry flag! :)

2014-12-27T17:59:53 < jpa-> just a note, stm32fxxx.h headers do not have all the registers, so do not trust it

2014-12-27T18:01:58 < ReadError> luckily this guy 'clive1' on the st forums is a beast and pretty much comes up in all my googling w/ good examples
2014-12-27T18:02:07 < jpa-> though there is the stdperiph documentation.. somewhere

2014-12-27T18:05:01 < jpa-> i often use chibios hal, which actually makes stuff easier not harder; other times, yeah, i use the registers directly

2014-12-27T18:06:02 < qyx_> although chibios hal has its own drawbacks sometimes
2014-12-27T18:06:14 < ReadError> with chibios
2014-12-27T18:06:41 < jpa-> qyx_: yeah, usually it only allows one way of using the peripheral
2014-12-27T18:06:59 < qyx_> and too much #defines and compile-time configuration
2014-12-27T18:07:15 < ReadError> maybe i should look at that before i get too invested in learning stdperiph
2014-12-27T18:07:28 < jpa-> yeah, compile time config is also a trade-off, ok for most purposes but makes things difficult if you want to reconfig dynamically
2014-12-27T18:08:01 < qyx_> last time i was trying to achieve dynamic clock reconfiguration
2014-12-27T18:08:24 < jpa-> yeah, that is a pain, and chibios makes that pain worse
2014-12-27T18:08:38 < jpa-> though i haven't yet seen a HAL that makes that easier
2014-12-27T18:09:02 < ReadError> hmm it looks like their HAL makes thinks easier
2014-12-27T18:09:10 < ReadError> like pwm looks pretty simple
2014-12-27T18:10:07 < jpa-> pwm is pretty simple even with raw registers
2014-12-27T18:10:32 < jpa-> better indication is to compare i2c or spi or usb or other complex peripheral
2014-12-27T18:11:09 < ReadError> yea the i2c stuff looked pretty easy too
2014-12-27T18:11:58 < ReadError> its supposed to be crazy low resource and fast too isnt it?
2014-12-27T18:12:14 < jpa-> dunno about "crazy"
2014-12-27T18:12:29 < jpa-> i would say typical low resource, non-bloat implementation

2014-12-27T18:49:06 < jadew> I guess I'll have to get some trimmer caps too, but till then, this will have to do
2014-12-27T18:49:43 < jpa-> remember to factor in the capacitance of the pcb traces and wires, it is quite significant at 0.01pF
2014-12-27T18:49:46 < jadew> GargantuaSauce_, good point, I guess I'll see what the results are
2014-12-27T18:49:53 < GargantuaSauce_> you could make a moveable plate air-dielectic capacitor pretty easily
2014-12-27T18:49:59 < GargantuaSauce_> like is in old radios
2014-12-27T18:51:06 < jadew> jpa-, yeah, I know - ideally I guess I'd make this capacitor directly on the pcb
2014-12-27T18:51:26 < GargantuaSauce_> that is actually probably the best bet
2014-12-27T18:51:31 < jpa-> or redesigning the circuit so that you can trim it, if it really needs such accurate values

2014-12-27T20:09:36 < qyx_> The capacitance is a function only of the geometry (including their distance) of the conductors and the permittivity of the dielectric

2014-12-27T20:31:08 < Laurenceb_> I was trying to design a balloon mounted ~10Mhz loop antenna
2014-12-27T20:31:30 < Laurenceb_> with the loop made of foil built into the envelope, so it needed automatic retuning
2014-12-27T20:32:06 < Laurenceb_> the loop developed +-50V, so varicaps got annoying
2014-12-27T20:32:38 < jpa-> i wonder if the techniques used in modern cellphones for automatic antenna tuning are available in any easy-to-use chips
2014-12-27T20:33:11 < Laurenceb_> there is a nice one from ST, but i cant find it anywhere
2014-12-27T20:33:13 < jpa-> though they are probably designed for operation only around 1GHz freqs
2014-12-27T20:33:19 < Laurenceb_> yeah, that too
2014-12-27T20:33:37 < Laurenceb_> the only solution i could get to work in spice was a ton of varicaps
2014-12-27T20:33:39 < Laurenceb_> 20 iirc
2014-12-27T20:34:10 < jpa-> servo and trimmer cap :)

2014-12-27T23:08:10 < Laurenceb_> i think some shipped...
2014-12-27T23:08:21 < Laurenceb_> dunno if they are at all functional tho
2014-12-27T23:08:38 < Laurenceb_> most of the graphics seems to be renderings
2014-12-27T23:08:44 < jadew> they were advertised as functional since the very begning
2014-12-27T23:09:15 < Laurenceb_> erm I mean the shipped semi prototype stuff, not sure if it has all the features
2014-12-27T23:09:21 < Laurenceb_> it was to kickstarter backers only

2014-12-28T01:56:06 < yan_> anyone using the stm32l1-discovery board? is it possible to get a uart link without an external uart connection? i.e. can i printf() over the stlink?
2014-12-28T01:58:58 < zyp> sure
2014-12-28T01:59:55 < zyp> IIRC the stlink is hooked up to one of the uarts and can act as a usb to serial adapter
2014-12-28T02:00:11 < zyp> or maybe I misremember, I'm not 100% sure on that
2014-12-28T02:01:04 < zyp> apart from that you could print through semihosting or swo

2014-12-28T22:00:19 < jpa-> yeah, seems that gcc only has 128 bit integers on 64 bit targets
2014-12-28T22:01:32 < zyp> kakeman, crypto, curve25519 is crypto stuff
2014-12-28T22:01:59 < jpa-> ttmath might be a reasonable implementation
2014-12-28T22:04:52 < kakeman> it has wicked name
2014-12-28T22:05:23 < kakeman> and some wicked math
2014-12-28T22:05:42 < zyp> well, duh, it's crypto
2014-12-28T22:06:13 < Getty> oh yeah... work if debugging is added and dont work if the debugging is out.... you just gotta love C
2014-12-28T22:06:26 < jpa-> i wonder if clang supports int128 on 32-bit targets
2014-12-28T22:06:44 < zyp> Getty, that means you're relying on undefined behavior
2014-12-28T22:06:46 < jpa-> ellcc.org is being slow so will take 20 minutes before i know :)
2014-12-28T22:06:50 < zyp> which is a programmer error ;)
2014-12-28T22:07:09 < Getty> zyp: could be! yeah! i am learning still a bit ;)
2014-12-28T22:07:18 < Getty> zyp: this is the code which i need to add so that it works: https://gist.github.com/Getty/92be61ba5e086abb01f3

2014-12-28T22:07:44 < jpa-> printf() is crazy slow anyway, so probably some timing bug
2014-12-28T22:07:47 < Getty> zyp: and it totally confuses me, cause this code does "nothing", and so far at least someone else said that the rest of my code is right, i mean.... it works if this "block" is in
2014-12-28T22:08:10 < jpa-> try putting a usleep(10000); or something instead
2014-12-28T22:08:22 < Getty> would be crazy, but lets try

2014-12-28T22:09:46 < Steffanx> ( why no switch statement Getty? )
2014-12-28T22:10:01 < Getty> that is actually not my code, that is like taken out of the "working function"
2014-12-28T22:10:08 < Steffanx> yay
2014-12-28T22:10:11 < Getty> beofre i copied only all the code that "actually does something"
2014-12-28T22:10:13 < Getty> which made sense
2014-12-28T22:10:14 < Getty> but it didnt worked

2014-12-28T22:10:18 < Getty> so i added this debugging block too
2014-12-28T22:10:22 < Getty> and BANG, it works 8-)
2014-12-28T22:10:28 < Getty> and now i am sitting here and thinking...... wtf
2014-12-28T22:11:12 < Getty> where i get usleep from?
2014-12-28T22:11:32 < jpa-> use whatever function gives a delay on your platform
2014-12-28T22:11:54 < jpa-> if you have none, some   for (int i = 0; i < 100000; i++) volatile asm("nop");   might work
2014-12-28T22:14:11 < Getty> that actually doesnt work
2014-12-28T22:14:25 < Getty> but i cant see the compile error, i must cleanup the code to get rid of the yet not relevant warnings.... baeh what a mess
2014-12-28T22:14:42 < Getty> i put 10 printf ;)
2014-12-28T22:15:09 < Getty> ok printf alone is not helping

2014-12-28T22:18:43 < jpa-> what does the code do?
2014-12-28T22:19:04 < jpa-> (and especially, what does it do when it does not work?)
2014-12-28T22:19:05 < Getty> i am actually reading a msgpack inside a cdb file
2014-12-28T22:19:25 < Getty> it gives back a wrong value, it seems like that the pointer which actually stores the information i want to access points to something random

2014-12-29T02:26:24 < englishman> rly, i copied from datasheet
2014-12-29T02:26:27 < dongs> not 9.95

2014-12-29T02:26:31 < dongs> datasheet is fucked or something
2014-12-29T02:26:41 < dongs> i was doing altium footprint for it

2014-12-29T02:26:51 < Laurenceb_> yeah this sucks with no 7 day delivery

2014-12-29T02:26:55 < dongs> but wanted to confirm
2014-12-29T02:27:06 < Laurenceb_> i wonder if they do DHL
2014-12-29T02:27:10 < dongs> and i see their 'suggested footprint' for CSTCE or wahtever was 0.9mm pitch
2014-12-29T02:27:21 < dongs> but i measured with my hobbyking pro meter
2014-12-29T02:27:24 < dongs> and it was 1.2mm between pads
2014-12-29T02:27:25 < dongs> so i duno
2014-12-29T02:27:27 < dongs> it still fits
2014-12-29T02:27:29 < dongs> just looks dum
2014-12-29T02:27:39 < englishman> i think there were two, one with 1.2mm and thin pads and one with 0.95 but thicker outer pads
2014-12-29T02:27:41 < englishman> so both work
2014-12-29T02:27:44 < englishman> agree: dumb

2014-12-29T02:42:37 < dongs> whats the point of 1gsps 14bit adc when its 10enob at 10mhz already.

2014-12-29T03:03:37 < dongs> if youre spending $500 on adc, whats another $500 on a virtex 7 or wahtever teh fuck current $$$ shit is
2014-12-29T03:04:49 < upgrdman_> hmmm. 1GSps, 14bits... so 14Gbps + overhead. ya, that should be doable with i2c ;)

2014-12-29T03:09:43 < emeb> a word
2014-12-29T03:09:57 < emeb> plus it's got a couple tuner/decimators in it
2014-12-29T03:10:12 < emeb> so this is clearly aimed at a multi-channel receiver.
2014-12-29T03:10:35 < emeb> probably some sort of SIGINT stuff commisioned by the military/industrial complex
2014-12-29T03:10:35 < dongs> so what does that do?
2014-12-29T03:10:40 < dongs> haha
2014-12-29T03:11:35 < emeb> 1 GSPS with tuner decimator lets you do broadband SDR stuff
2014-12-29T03:12:21 < dongs> yes but who'd need that much bandwidth to analyze
2014-12-29T03:12:44 < emeb> ADI does a lot of high-end research projects for Gov't that they're allowed to put in their catalog when they're done.

2014-12-29T17:11:34 < rewolff> I too would like to know how to get rid of the nucleo "mass storage" behaviour.
2014-12-29T17:12:03 < Steffanx> reprogram the programmer part :P
2014-12-29T17:13:07 < ReadError> ya need alternative firmware for the stlink
2014-12-29T17:14:23 < rewolff> Huh? It's STLINK V2-1, that is NOT an upgrade from STLINK V2 ???? ?
2014-12-29T17:14:57 < rewolff> I thought I could send it "something" that it would revert to STLINK V2 mode.
2014-12-29T17:15:25 < inca> rewolff: look at the boot modes
2014-12-29T17:15:26 < ReadError> well when you go to update the firmware with STLINK app, it has "+Mass storage" at the end of the name
2014-12-29T17:16:05 < rewolff> Boot modes? Of the '103 chip?
2014-12-29T17:16:45 < rewolff> Sure that's a feature, that's neat and all, but I wasn't planning on using it. It is the part before the "+ mass storage" that I thought would still be there.
2014-12-29T17:17:02 < rewolff> I don't have windows, I dont have "stlink app".
2014-12-29T17:18:54 < karlp> rewolff: why does it matter?
2014-12-29T17:19:07 < karlp> oocd just opens it up like normal anyway...
2014-12-29T17:19:17 < rewolff> Oh. I use "st-util".
2014-12-29T17:19:38 < rewolff> Tried switching to openocd once, got stuck when I had to configure things for different processors.
2014-12-29T17:19:49 < ReadError> http://i.snag.gy/z9aRF.jpg
2014-12-29T17:19:52 < ReadError> hmm
2014-12-29T17:19:54 < rewolff> st-util just tells me: You've got a 16k flash, 2k RAM chip attached.
2014-12-29T17:19:59 < ReadError> i wonder if I click yess it will remove that
2014-12-29T17:20:06 < rewolff> Or "youve got a 1M flash, 192k RAM".
2014-12-29T17:21:36 < ReadError> nope didnt ;(
2014-12-29T17:21:49 < rewolff> I've got about ten different STM32F processors on my desk at the moment....
2014-12-29T17:22:15 < rewolff> I would think that the J23 means it's version 23 of the JTAG code,
2014-12-29T17:22:31 < rewolff> and M7 is the mass storage driver Version 7.
2014-12-29T17:29:02 < rewolff> karlp: so you're saying that openocd knows "the way" to trigger the mass storage -> stlink conversion....
2014-12-29T17:30:02 < karlp> sure, just like the DFU-stlink conversion it already does for instance.
2014-12-29T17:30:22 < karlp> if the mounting of it bothers you though, you can use a udev quirk thing just like for the stlinkv1
2014-12-29T17:30:50 < karlp> st-util _should_, but I don't follow that codebase anymore.
2014-12-29T17:31:39 < rewolff> http://fabooh.com/2014/02/25/openocd-meets-a-nucleo-f030r8-board/
2014-12-29T17:32:08 < rewolff> It seems it enumerates as the stlink as well, but under a different PID, so maybe a small patch is required.
2014-12-29T17:32:47 < rewolff> I've enough discovery boards to get by so far, but knowing the problem is solvable is nice-to-know

2014-12-29T17:53:36 < karlp> you could send it commands wrapped up in scsi/sg commands, but most tools moved to just raw libusb very quickly

2014-12-29T19:25:47 < karlp> at least for the stimulus channels.  tracing data accesses not so much
2014-12-29T19:26:14 < karlp> I did some preliminary pc sampling based profiling the other day, but no tools integration
2014-12-29T19:26:50 < karlp> oocd can reconnect to stlinks more reliably now when they lose sync with the targt, that's handy, for general use I can now just start openocd and leave it running even after plugging/unplugging the target
2014-12-29T19:27:13 < karlp> I've heard they've got SWD working on FTDI based dongles, but I'm still only on the stlink really.

2014-12-29T20:35:55 < zyp> I don't remember the specific issues I were having
2014-12-29T20:36:44 < decimad> zyp: So it's not feature set but rather bugs?
2014-12-29T20:37:04 < qyx_> bugset
2014-12-29T20:37:18 < decimad> I was just wondering if there can be a functional difference, given it must be a gdb server...
2014-12-29T20:37:41 < zyp> eh, somewhere in between, I guess
2014-12-29T20:38:21 < zyp> keep in mind the gdbserver is not the main interface for the jlink
2014-12-29T20:38:52 < zyp> but I don't care about the commercial IDEs they also support
2014-12-29T20:39:00 < zyp> or the standalone flasher app

2014-12-30T01:06:02 < qyx_> i was trying to persuade it to build every part of the project as a standalone static library
2014-12-30T01:06:11 < qyx_> and then link the whole thing
2014-12-30T01:06:34 < qyx_> but.. i gave up after spending too much time resolving undefined references
2014-12-30T01:06:41 < zyp> that's pointless
2014-12-30T01:07:16 < qyx_> now i return objects from different sconscripts and link them in the main sconstruct file
2014-12-30T01:07:28 < zyp> a static library is just an archive of object files
2014-12-30T01:07:43 < qyx_> yes but during linking the order matters
2014-12-30T01:08:01 < zyp> and when you're building everything with the same framework, there's no point to collect the object files into archives before linking
2014-12-30T01:09:10 < zyp> actually, as I learned recently, there's a way to get around that

2014-12-30T01:11:09 < zyp> heh
2014-12-30T01:11:10 < qyx_> maybe i will redo it that way later
2014-12-30T01:11:16 < zyp> quoting the manual: «Using this option has a significant performance cost. It is best to use it only when there are unavoidable circular references between two or more archives.»

2014-12-30T01:24:11 < zyp> you need to be mindful of strings vs path objects
2014-12-30T01:24:40 < zyp> a relative path is relative to the reference directory where the string gets turned into a path object
2014-12-30T01:25:38 < zyp> passing plain strings between sconscripts means they might be turned into paths at the wrong point, so it's better to be explicit about that
2014-12-30T01:26:36 < zyp> http://cgit.jvnv.net/laks/tree/build_rules <- see for instance the three first lines here
2014-12-30T01:27:11 < zyp> by using Dir() and File() I'm ensuring that they are relative to the directory containing the build_rules file, i.e. the root directory of the laks library
2014-12-30T01:28:29 < zyp> those variables are used by the SelectMCU function, and if they were plain strings instead, they would be treated as relative to the file calling the SelectMCU function instead

2014-12-30T02:44:57 < inca> qyx_: why not CMake?
2014-12-30T02:45:17 < inca> e.g. that module approach you were just talking about: http://www.wias-berlin.de/people/fuhrmann/2014-10-30-cmake.html#cmakelists.txt
2014-12-30T02:45:36 < kakeman> is berlin nice place?
2014-12-30T02:48:24 < qyx_> inca: because i don't like the idea of building in two passes
2014-12-30T02:56:34 < inca> I wasn't aware that we still had a choice... pretty sure gcc is an N-pass compiler... and even our basic Makefiles have dependency calculations...
2014-12-30T03:00:40 < inca> qyx_: and if the CMake imperative style isn't your thing, GYP's declarative (lisp-esque) might be more the way to go...
2014-12-30T03:01:26 < inca> Both support Ninja, which is faster than "make" and more make-like in spirit than make these days... except for its lack of fortan support.
2014-12-30T03:06:26 < qyx_> and because i already know python
2014-12-30T03:06:35 < qyx_> i was investigating cmake a bit

2014-12-30T04:01:55 < dongs> cmake is some german filth
2014-12-30T04:01:56 < inca> zyp: I've been using it as a meta-make, somewhat like autoconf but without as much autotools mess. In a few cross compiles, it has been useful as a pseudo package system to help with toolchain builds and the subsequent builds which depend on that toolchain. I'll try to dig up some good examples...
2014-12-30T04:05:37 < zyp> inca, also, why not scons? you seem to insist on not using it
2014-12-30T04:09:42 < inca> zyp: there is a lot of cultural knowledge in the old Makefile systems which CMake inherets and the SCONS folks are relearning. There is some improvement along the way, but my impression is that it is incomplete. Though most are arguably incomplete. Additionally, I am not a fan of Python syntax. But that's really neither here nor there. =)
2014-12-30T04:10:58 < inca> at the end of the day, I am really not satisfied with any of the build systems these days... though I am the least dissatisfied with CMake/Ninja combo or GYP/Ninja
2014-12-30T04:11:48 < zyp> I'm inclined to read cultural knowledge as legacy bullshit
2014-12-30T04:11:57 < inca> here's a cross compile example for CMake which builds a windows toolchain on linux, then a rather large library of support packages with the toolchain, then the MPV executable: https://github.com/lachs0r/mingw-w64-cmake
2014-12-30T04:12:47 < inca> zyp: yeah, it is sometimes best to start fresh and redo everything.
2014-12-30T04:13:46 < inca> the thing I like about CMake/Ninja is that it gets pretty close to the original
2014-12-30T04:13:53 < inca> Makefile intent
2014-12-30T04:14:51 < zyp> I'm obviously biased by already being a python developer
2014-12-30T04:15:15 < inca> CMake handles dependencies, which are not trivial to calculate because only the preprocessor really can know this, and then Ninja makes without thinking about dependencies.
2014-12-30T04:15:26 < inca> it's true... go with what you know
2014-12-30T04:16:11 < inca> and I'll be straight honest with you, I learned perl before python and I tend to prefer it for the syntactic ease and community in general.
2014-12-30T04:16:20 < inca> perl, that is
2014-12-30T04:17:17 < zyp> «syntactic ease»
2014-12-30T04:17:23 < zyp> what part of perl syntax is easy? :p
2014-12-30T04:18:28 < inca> 3 data types, everything is a string... data conversion becomes trivial once we escape strongly typed enforcement
2014-12-30T04:19:18 < zyp> I don't understand how that's supposed to be advantages :)
2014-12-30T04:19:58 < inca> it's kind of a mind set... you learn the simple hammer for 3 kinds of nails and then break everything down into those terms. Since ot
2014-12-30T04:20:22 < zyp> so that's strings, arrays and hashmaps then?
2014-12-30T04:20:24 < inca> since it's data-oriented, it's powerful in a sense, but limited in terms of code-correctness, reusability, etc.
2014-12-30T04:20:32 < inca> basically, yes.
2014-12-30T04:21:20 < inca> everything else is a transform on those basic data types... or representations of the data
2014-12-30T04:21:32 < zyp> I see
2014-12-30T04:23:20 < inca> so python is better for someone to pick up someone else's code and extend it, but a little more painful for being explicit with the types and all that. It's a give-and-take on the flexibility. It's good for the quick hack, but can hurt readability and reusability without a strong community to enforce standards... which perl sometimes has.
2014-12-30T04:23:26 < dongs> uh
2014-12-30T04:23:29 < dongs> are you fucking serious
2014-12-30T04:23:35 < dongs> python is completely unreadable trash
2014-12-30T04:23:39 < dongs> write-once code
2014-12-30T04:23:42 < zyp> so, would you say perl could be a good tool for interfacing with usb devices through libusb?
2014-12-30T04:23:54 < dongs> zyp, no, C is
2014-12-30T04:24:04 < zyp> because that's one of the things I do a lot of in python
2014-12-30T04:24:26 < inca> if it were a one time setup, sure... but if there's throughput at stake, I'd use C

2014-12-30T04:24:38 < zyp> dongs, sure, but that's too tedious
2014-12-30T04:24:55 < zyp> inca, I'm not talking throughput, I'm talking utility scripts
2014-12-30T04:25:08 < inca> for setting up devices and such?
2014-12-30T04:25:52 < zyp> config/test/whatever
2014-12-30T04:26:08 < inca> I don't see anything wrong with that
2014-12-30T04:26:18 < inca> it's fast, flexible...

2014-12-30T04:26:44 < zyp> I'm having problems imagining dealing with binary data in a language without suitable types
2014-12-30T04:27:30 < inca> in the "everything is a string" mindset, it becomes hexadecimal (or whatever you want to visualize it as)
2014-12-30T04:28:18 < zyp> so in practice you get different types of strings
2014-12-30T04:28:33 < zyp> so the typing is just on a higher level
2014-12-30T04:28:47 < inca> basically
2014-12-30T04:29:37 < inca> http://perldoc.perl.org/perlpacktut.html
2014-12-30T04:30:44 < inca> actually found the examples here to mean more to me: http://perldoc.perl.org/functions/pack.html
2014-12-30T04:30:44 < zyp> looks very similar to python's struct module
2014-12-30T04:30:57 < inca> at the end of that link
2014-12-30T04:31:05 < inca> I'd imagine so
2014-12-30T04:31:19 < zyp> https://docs.python.org/2/library/struct.html
2014-12-30T04:31:50 < inca> yep, very similar
2014-12-30T04:41:32 < inca> in any case, hope that CMake example might help you out. I haven't done my own cross compile setup yet in CMake, but the next time I do it'll likely look a bit like lachs0r's
2014-12-30T04:42:00 < inca> (for embedded cross compile)
2014-12-30T04:42:16 < inca> I've been doing tons of linux->win32 cross compile lately
2014-12-30T04:42:40 < zyp> I were thinking more about cross compiling for embedded though
2014-12-30T04:42:56 < inca> it's the same concept, really
2014-12-30T04:43:26 < zyp> and I'm not really looking to replace scons, I've just heard other people claim otherwise about cmake's suitability for embedded
2014-12-30T04:43:51 < inca> build stuff you can't run locally. build more stuff which depends on that stuff. wave magic linker at it. copy, run, pass/fail
2014-12-30T04:44:22 < inca> save for the toolchain, obviously, but you get the idea
2014-12-30T04:44:47 < zyp> http://cgit.jvnv.net/laks/tree/build_rules <- I like the way I can write functions to configure stuff in a language I'm familiar with
2014-12-30T04:45:30 < zyp> http://cgit.jvnv.net/arcin/tree/SConstruct <- which makes it this easy to build a project based on my library
2014-12-30T04:48:42 < dongs> lol scons
2014-12-30T04:49:06 < dongs> < inca> I've been doing tons of linux->win32 cross compile lately
2014-12-30T04:49:09 < dongs> why the fuck
2014-12-30T04:49:13 < dongs> would anyoen bulid windows apps on lunix?
2014-12-30T04:49:32 < dongs> you do realize that msvc compilers (even gimped free ones) are lightyears ahead of gcc in performance of generated code?
2014-12-30T04:51:10 < zyp> but is it really?
2014-12-30T04:51:23 < dongs> yes
2014-12-30T04:51:45 < dongs> do you see microsoft building windows kernerl wiht gcc? no.
2014-12-30T04:52:06 < GargantuaSauce_> lol
2014-12-30T04:52:50 < dongs> just like armcc is >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> gcc for cortex code, same is msvc for windows apps
2014-12-30T04:53:04 < GargantuaSauce_> >implying anyone writes native windows apps
2014-12-30T04:53:49 < zyp> I googled gcc vs msvc comparisons, and from the numbers I see, gcc is faster in most benchmarks
2014-12-30T04:54:02 < dongs> 'faster' to compile?
2014-12-30T04:54:11 < zyp> produces faster code
2014-12-30T04:54:15 < dongs> unlikely
2014-12-30T04:54:22 < dongs> sauce plz
2014-12-30T04:54:48 < zyp> https://www.google.no/search?q=msvc+vs+gcc+performance
2014-12-30T04:55:11 < zyp> I went through multiple of the hits, and the general concencus seems to be that gcc is faster
2014-12-30T04:56:52 < inca> dongs: I doubt vlc cares
2014-12-30T04:57:01 < dongs> vlc surely does not
2014-12-30T04:57:09 < dongs> thier code is so full of gcc garbage it probably wont even compile with a real compiler
2014-12-30T04:58:08 < inca> clang seemed to do okay when I tried
2014-12-30T04:58:36 < inca> but gcc 4.9 was the one I used in the end
2014-12-30T05:00:10 < inca> dongs: to answer your question about why, because it's more controllable, automatable, and cheaper to do on Linux
2014-12-30T05:00:36 < inca> and, if google is to be believed, more perfomant ;)
2014-12-30T05:00:43 < ds2> but it does not create jobs and support the economy
2014-12-30T05:00:47 < dongs> enjoy your aids
2014-12-30T05:01:39 < GargantuaSauce_> what a cop out dongs. come on you can do better than that
2014-12-30T05:02:52 < inca> the Open Sores are catching up... to Property Sores

2014-12-30T09:59:44 < dongs> and I had last GPS coordinates
2014-12-30T09:59:48 < dongs> that would be the FIRST place I'd check
2014-12-30T09:59:56 < dongs> not,,, Nth place on 3rd day
2014-12-30T10:03:05 < englishman> those bitches never drop straight down tho
2014-12-30T10:03:17 < englishman> you can glide a pretty long way from 30k ft
2014-12-30T10:04:51 < dongs> well, apparently this one didnt
2014-12-30T10:09:24 < englishman> iirc it took a week to find that air france flight and they knew right where it went down

2014-12-30T10:10:20 < dongs> like 50meters or even less in that area
2014-12-30T10:10:22 < dongs> not gonna take long
2014-12-30T10:10:32 < englishman> oh
2014-12-30T10:10:46 < englishman> could even see it
2014-12-30T10:10:47 < dongs> or in that whole area in general, teh sea is shitty, just like the countries around it

2014-12-30T12:03:56 < ReadError> oh okay, so busy is set if SDA or SCL is detected as being pulled low, stuff is starting to add up i guess

2014-12-30T12:28:15 < ReadError> i need to double check on SDA, when i power the OLED screen SCL is getting pulled high but SDA stays low after the GPIO_Init

2014-12-30T12:29:06 < ReadError> nothing ive added no

2014-12-30T12:29:22 < qyx_> *opendrain
2014-12-30T12:29:35 < qyx_> you either have to use internal pullups at slower speed or external
2014-12-30T12:30:33 < qyx_> if you configure your SDA as opendrain and OLED is also opendrain, there is nothing that would pull your SDA line up
2014-12-30T12:31:48 < qyx_> changing your PUPD init should be enough
2014-12-30T12:35:40 < ReadError> yea I tried internal pullup as well
2014-12-30T12:35:59 < ReadError> ill keep dicking with it, but yea fairly sure its something related to that

2014-12-30T14:31:40 < ReadError> if I set the pin as input
2014-12-30T14:31:49 < ReadError> and no pull, its being pulled high externally
2014-12-30T14:32:06 < ReadError> its something to do with Mode_AF that is causing it to be pulled low
2014-12-30T14:32:21 < jpa-> remember that i2c pins should be configured as opendrain, not output
2014-12-30T14:32:46 < ReadError> yea, but I just did this to confirm that there is something pulling up externally
2014-12-30T14:34:46 < jpa-> yeah :)
2014-12-30T14:34:51 < qyx_> why are you confirming it?
2014-12-30T14:35:27 < ReadError> to confirm its something to do w/ the Mode_AF that is pulling it now
2014-12-30T14:35:32 < ReadError> now=low
2014-12-30T14:36:21 < qyx_> and why are you assuming it is pulled high if configured as input?
2014-12-30T14:36:25 < qyx_> it may be floating
2014-12-30T14:37:10 < ReadError> well im scoping the GPIO pin
2014-12-30T14:37:28 < ReadError> and if I unplug SDA it goes from high->low
2014-12-30T14:37:50 < qyx_> instead of randomly trying insane things you should start with working configuration and schematics
2014-12-30T14:38:10 < qyx_> there is i2c bus explained in the oled datasheet
2014-12-30T14:38:26 < qyx_> should be, it is in most datasheets of i2c peripherals

2014-12-30T15:53:42 < dongs> that too, or require gcc to compile
2014-12-30T15:54:02 < dongs> requiring gcc and all the files in 10000 directories is pretty much a deal breaker for me

2014-12-30T15:58:44 < PaulFertser> All CAPS is customary for macros, not appropriate for the function names. What's better: to follow the best C programming practicies or some stupid refman when it comes to capitalisation?
2014-12-30T15:59:24 < dongs> I'd say follow the fucking CMSIS
2014-12-30T15:59:29 < dongs> and not rename teh vectors
2014-12-30T15:59:59 < dongs> Its not all caps in CMSIS either

2014-12-30T16:03:53 < karlp> there's a chunk inside locm3 called libopencmsis that provides a few wrappers for some of this, it would be nice to unify it all of course, but it wasn't at the time

2014-12-30T16:07:45 < dongs> now with openAIDScm3, you dont know which vector is standard or which one is vendor
2014-12-30T16:07:55 < dongs> pendsv_isr is it?
2014-12-30T16:08:08 < dongs> seems, according to gogole ^_^
2014-12-30T16:09:07 < karlp> pend_sv_handler, apparently
2014-12-30T16:09:11 < karlp> so _handler and _isr
2014-12-30T16:09:18 < dongs> uh really
2014-12-30T16:09:27 < dongs> i see google doing pendsv_isr
2014-12-30T16:09:35 < dongs> looks like your shit is evne less consistent : )
2014-12-30T16:09:49 < karlp> pendsv_isr isn't in libopencm3 code
2014-12-30T16:09:53 < karlp> but sure, it's in google,
2014-12-30T16:09:57 < karlp> someone used that naming
2014-12-30T16:10:24 < karlp> guess libopencm3 and cmsis are sameish then, _handler/Handler and _isr/IRQHandler

2014-12-30T18:24:14 < karlp> and digikey said, "fuck it" and said, "if you don't pay it, you can't buy from us again"

2014-12-30T20:54:48 < BrainDamage> ups reports package delivery failed when the original ETA would've been passed and you must manually arrange delivery, except if you actually track the package it's still hundreds km away and has yet to reach local dispatch, then they magically mark it delivered the day after, despite the truck didn't pass yet, and finally the day after, after i start complaining, they finally actually deliver it
2014-12-30T20:54:57 < BrainDamage> this happened 2 times in a row
2014-12-30T20:55:42 < Getty> our main german delivery company has a new trend, that the package might be on the "last truck" for like 3 days
2014-12-30T20:55:58 < Getty> so you actually see in the tracking that the package is "on the truck for delivery to customer"
2014-12-30T20:56:16 < Getty> and you wait all day, like a child "are they coming now? are they coming now?" and at some point you realize there is no bone today....
2014-12-30T20:56:25 < Getty> what you think? yeah sure, will come tomorrow... logical, right? right!
2014-12-30T20:56:39 < englishman> sounds efficient
2014-12-30T20:56:45 < Getty> oh trust me... the anger on the evening of the next day when you see you are screwed up again.....
2014-12-30T20:57:06 < Getty> yeah some deliveries are just more important than others ;) whatever, it was frustrating
2014-12-30T20:57:14 < Getty> and thats now a regularity
2014-12-30T21:01:26  * Tectu now knows how jpa- must be feeling.
2014-12-30T21:01:34 < Tectu> was sking with -19°C
2014-12-30T21:01:34 < jpa-> ?
2014-12-30T21:01:48 < jpa-> i'm feeling warm and cozy
2014-12-30T21:02:26 < Tectu> you mentioned some -25°C action
2014-12-30T21:02:29 < BrainDamage> why would you go skiing with such awful air temp
2014-12-30T21:02:42 < Steffanx> no apres ski?
2014-12-30T21:02:48 < Tectu> Steffanx, lots of that as well
2014-12-30T21:02:48 < Getty> why would someone go skiing at all..... ;-)
2014-12-30T21:02:54 < Steffanx> ^^ that
2014-12-30T21:02:55 < Tectu> BrainDamage, because it was a warm day after all LOL
2014-12-30T21:03:23 < BrainDamage> i don't know there but here there's awfully strong and cold gusts
2014-12-30T21:03:24 < Tectu> because one has a fucking girlfriend who wanted to and because one was fucking stupid enough to promise her during nice and warm temperatures that you will go with her
2014-12-30T21:03:27 < Getty> yeah apres ski sounds nice, like going there, sleeping all day, and then go party with the ski people, just putting on the suit ;-)
2014-12-30T21:03:39 < Tectu> a lot of local people there do that
2014-12-30T21:04:13 < BrainDamage> why go skiing? because rush of adrenaline of being directly in control of yourself moving at relatively high speed
2014-12-30T21:04:46 < Tectu> that or because the after-ski-sex
2014-12-30T21:05:51 < BrainDamage> what's why you go to after ski, not why you ski, you could spend the time at the chalet :p
2014-12-30T21:07:40 < Tectu> meh
2014-12-30T21:07:54 < qyx_> mhm, never happened with UPS here
2014-12-30T21:08:23 < qyx_> when the tracking says "delivering" it is always delivered the same day
2014-12-30T21:08:48 < qyx_> i mean delivering to the customer, the "last truck"
2014-12-30T21:08:54 < Tectu> when it says delivered it always takes one or two days to be actually delivered here
2014-12-30T21:09:06 < Tectu> cuz UPS gives it to swiss post office on swiss border
2014-12-30T21:09:14 < Tectu> and they sign that they received it...
2014-12-30T21:09:23 < qyx_> lo
2014-12-30T21:09:25 < qyx_> l
2014-12-30T21:09:45 < Tectu> so tracking really works just outside switzerland :P
2014-12-30T21:10:30 < qyx_> i should make a list of things which are actually better in central/east EU than in the west countries
2014-12-30T21:10:44 < qyx_> although probably it wont be long
2014-12-30T21:10:49 < Tectu> I could contribute at least three dozen points
2014-12-30T21:11:13 < Tectu> qyx_, but afaik your country is still one of the nice east countries, no?
2014-12-30T21:11:26 < qyx_> don't know, could be
2014-12-30T21:13:02 < qyx_> ok, my beaky-style boost converter with F030 doesn't workj as expected
2014-12-30T21:15:25 < BrainDamage> what is a little know but useful feature of beaky?
2014-12-30T21:15:29 < qyx_> i should select n-mosfet with lower total gate charge if i am going to drive it directly
2014-12-30T21:15:59 < qyx_> beaky was a guy making a charger with F42x
2014-12-30T21:17:02 < qyx_> having MCU to control charging  isn't THAT bad idea.. but he started from wrong direction

2014-12-31T04:49:17 < GargantuaSauce_> makes sense i guess. just figure out your max current and then size the resistor to make the drop at that current just less than the difference between the supply voltage and the ldo's dropout
2014-12-31T04:52:02 < upgrdman> k
2014-12-31T04:53:20 < GargantuaSauce_> or just use a switching regulator instead of pretending it's 1985
2014-12-31T04:53:43 < upgrdman> ya... but i have of free LDOs. maybe 200 of them :)

2014-12-31T07:23:13 < englishman> Many ways to send stuff to chip
2014-12-31T07:23:22 < englishman> Dfu, UART boot loader
2014-12-31T07:23:26 < emeb_mac> or get a STM32 with USB bootloader
2014-12-31T07:23:44 < emeb_mac> then put on a USB socket
2014-12-31T07:23:58 < englishman> Even f1 has a dfu lib, dongs has been using that
2014-12-31T07:24:00 < emeb_mac> populate the BOOT0 pin with a jumper
2014-12-31T07:24:05 < englishman> Digikey I guess?
2014-12-31T07:24:22 < emeb_mac> most STM32 F3/F4 with USB have the DFU bootloader
2014-12-31T07:25:46 < englishman> That's one way
2014-12-31T07:25:57 < englishman> You can make something more user friendly
2014-12-31T07:26:04 < englishman> But that'd be the easiest for you
2014-12-31T07:26:50 < englishman> Your own dfu program with big UPGRADE button simply
2014-12-31T07:27:13 < englishman> Can jump to dfu routine in firmware
2014-12-31T07:27:45 < englishman> Dfu over USB yes
2014-12-31T07:28:04 < englishman> Like emeb said f3/f4 most have USB dfu in rom
2014-12-31T07:28:11 < englishman> F1 you have to use own lib
2014-12-31T07:29:07 < englishman> Probably
2014-12-31T07:31:55 < upgrdman> when changing microcontrollers, but staying in the same STM32Fx series, the linker script stays the same except for the FLASH LENGTH and RAM LENGTH, right?
2014-12-31T07:32:41 < upgrdman> cool

2014-12-31T08:06:36 < englishman> Hmm guess not
2014-12-31T08:11:11 < englishman> Cuz its pretty chip specific
2014-12-31T08:11:59 < englishman> You know, those windows that let you view peripheral registers in memory map and have tooltip to remind you what every bit does
2014-12-31T08:13:14 < englishman> There's no reason why not. But I didn't see a screencap of it anywhere.
2014-12-31T08:13:29 < englishman> Free trial tho, will download n try
2014-12-31T08:14:41 < englishman> Of course
2014-12-31T08:14:47 < englishman> Its like $23

2014-12-31T08:23:18 < dongs> you can even make ethernet bootloader yourself
2014-12-31T08:24:02 < dongs> why not? you can do whatever you want
2014-12-31T08:24:12 < dongs> you decide how its used
2014-12-31T08:25:32 < dongs> there isnt one
2014-12-31T08:25:34 < dongs> you just write it
2014-12-31T08:25:50 < dongs> or find something on internets and adapt to your use
2014-12-31T08:26:12 < dongs> USB is probably easiest/smallest
2014-12-31T08:26:21 < dongs> and use ST DFU shit
2014-12-31T08:26:28 < dongs> if you dont care about people stealing your firmware
2014-12-31T08:27:08 < dongs> if you care, then add aes on top of that and write a tool to send it thats ~similar to ST DFU
2014-12-31T08:27:13 < dongs> well you write it in either case
2014-12-31T08:27:20 < dongs> on F1 at least, theres only serial bootloader
2014-12-31T08:27:26 < dongs> on F3/F4, tehre's USB DFU, in ROM
2014-12-31T08:27:33 < dongs> if you use that, you send your firmware in the clear
2014-12-31T08:27:38 < dongs> if you want encrypted, you gotta write your own
2014-12-31T08:28:22 < qyx_> uhm aes
2014-12-31T08:28:30 < qyx_> and wait until someone manage to extract your key
2014-12-31T08:28:47 < dongs> shrugging
2014-12-31T08:29:59 < qyx_> i wouldnt use any kind of symmetric encryption for this purpose
2014-12-31T08:30:14 < qyx_> as it implies giving my key to all
2014-12-31T08:30:14 < dongs> *plenty* of places do and haven't had a problem
2014-12-31T08:30:48 < dongs> well, if key is in bootloader and you have no backdoors, and you're ROP-protected, its prbly fine
2014-12-31T08:30:49 < qyx_> which defeats the one and only purpose of symmetric crypto
2014-12-31T08:31:06 < dongs> we're talking R2COM stuff here

2014-12-31T08:42:30 < qyx_> but if i had to, i would use rsa+aes
2014-12-31T08:42:35 < emeb_mac> that shit will leak through anything

2014-12-31T16:44:44 < PaulFertser> Tectu: hm, so you're going to reimplement some Qt widgets in uGFX? That's a cool idea. Just that or some additional declarative language or gui scripting too? BTW, why are you not using layout managers? I think many embedded programmers might be unfamiliar with the coolness layouts provide, so that might be an additional non-obvious hook for them (e.g. support any screen size, resolution, i18n
2014-12-31T16:44:50 < PaulFertser> without redesigning placements)?

2014-12-31T16:57:01 < Tectu> PaulFertser, I don't reimplement any Qt stuff in uGFX. The uGFX-Studio just uses the Qt framework. The application is completely written from scratch
2014-12-31T16:57:28 < Tectu> PaulFertser, I don't have layouts yet because I didn't have time to do them so far. What you see in the video is the resolut of a couple of weeks of work on the uGFX-Studio. There is a lot left to do.
2014-12-31T16:58:18 < Tectu> PaulFertser, the tool doesn't do much beside what you can see in the video yet. I will do some longer, commented video showing all the current features in a few days
2014-12-31T16:59:21 < PaulFertser> Tectu: oh, I see. I thought you were just going to reuse the classical QtDialog editor and take the description it generates.
2014-12-31T16:59:58 < Tectu> PaulFertser, not at all. I wanted to do that first but I figured that there will be way more tools beside the GUI designer in the uGFX-Studio at the end
2014-12-31T17:00:23 < Tectu> PaulFertser, and this way I have full control over the entire thing. Otherwise I'd rely on some 3rd party codebase that might change
2014-12-31T17:00:48 < PaulFertser> Yeah, and that would also require your target audience to keep in mind specific uGFX limitations when designing.
2014-12-31T17:01:27 < Tectu> yep
2014-12-31T17:01:55 < Tectu> the uGFX-Studio does also parse the library at startup so the studio does only provide the features that the user has in the uGFX library he uses :)
2014-12-31T17:02:09 < Tectu> also gives us the ability to add for example new fonts and colors to the library without changing the studio
2014-12-31T17:02:59 < karlp> yeah, because installing yet another single use code generator is _exactly_ what I want :)
2014-12-31T17:03:38 < Tectu> uGFX-Studio requires no installation ;-)

2014-12-31T20:25:55 < decimad2_> Anybody knows a good roundup on how the priorities of threads isr must be on chibios? The only small section I could find states that ISRs (there considered a type of task) have a priority above all threads (but below or equal the system tick, which I assume to be the "system level priority" refered to on all kind of places). But that would mean BASEPRI is set to 0xFF on all user threads? Any ISR can preempt any running thread?
2014-12-31T20:26:53 < decimad2_> Now I could probably parse the code, but I fear my lack of experience might misinterpret stuff.
2014-12-31T20:30:14 < decimad2_> I would expect that if thread A executes and is the highest priority thread, that not even the system tick will preempt it... but that would mean that BASEPRI is set to the system tick level then or the system tick level is reduced... but I cannot find documentation about all this :(
2014-12-31T20:37:23 < decimad2_> I'm sorry, I didn't know there was a dedicated channel, so please ignore my questions!

2014-12-31T20:40:27 -!- decimad2_ is now known as decimad
2014-12-31T20:44:15 < qyx_> decimad: threads are not isrs
2014-12-31T20:44:18 < Steffanx> that channel is pretty useless decimad
2014-12-31T20:44:39 < qyx_> and the other way around, isrs are not threads
2014-12-31T20:44:43 < qyx_> threads are just threads
2014-12-31T20:44:53 < qyx_> isr can preempt a thread
2014-12-31T20:45:31 < qyx_> and another isr (eg. systick) can preempt an isr depending on priority
2014-12-31T20:45:33 < decimad> qyx_: But that would mean that I need to do urgent stuff directly in ISRs to get a guaranteed priority level?
2014-12-31T20:45:59 < decimad> Where I don't even want to be preempted by short isr handlers?
2014-12-31T20:46:00 < qyx_> it depends what is urgent
2014-12-31T20:46:09 < qyx_> then yes
2014-12-31T20:46:36 < qyx_> but normally you would just save data and signal a semaphore or send a message to your thread (from isr)
2014-12-31T20:47:10 < decimad> qyx_: Would it be totally unreasonable to do threads and ISRs in the same priority scheme, so that BASEPRI is raised to the thread priority level when it is running?
2014-12-31T20:47:10 < qyx_> and the thread will preempt another thread if it has higher priority (if it is ready to run)
2014-12-31T20:47:26 < qyx_> isr priorities != thread priorities
2014-12-31T20:47:39 < decimad> qyx_: Yes, but what _IF_
2014-12-31T20:47:47 < decimad> it's totally doable I mean
2014-12-31T20:48:18 < qyx_> asking me what is reasonable is not a good idea
2014-12-31T20:49:37 < decimad> qyx_: I mean, nothing in ChibiOS-RT threads is realtime when those priority levels are apart :(
2014-12-31T20:50:13 < englishman> Isn't it up to you not to make isrs that take like days to execute.
2014-12-31T20:50:41 < englishman> Or do I misunderstand
2014-12-31T20:50:54 < englishman> Isrs are still the same as non rtos isrs, right
2014-12-31T20:51:24 < decimad> englishman: If I can be preempted by any ISR, short streaks of events or many parallel events will totally wreck my hight priority thread
2014-12-31T20:52:18 < englishman> How is that typically handled, does the isr simply call a new rtos thread with desired priority?
2014-12-31T20:52:20 < decimad> englishman: So I cannot reason about timing constraints in a user thread
2014-12-31T20:53:11 < englishman> Well I dono how that works typically, but its certainly one of those thing they have thought of, and probably have a way of dealing with it.
2014-12-31T20:53:44 < decimad> That may be, but the documentation is lacking and all I can read into stuff says the opposite :(
2014-12-31T20:53:45 < qyx_> wut, your user code can be preempted even if not using rtos
2014-12-31T20:54:19 < qyx_> and if you do not want this, you can mask interrupts
2014-12-31T20:54:22 < decimad> qyx_: Not if I set the BASEPRI on a value that my code is supposed to run on
2014-12-31T20:54:42 < qyx_> ok, lets define what an interrupt is
2014-12-31T20:54:51 < qyx_> as its name suggests, it is meant to interrupt something
2014-12-31T20:55:08 < qyx_> you want to have some god-level user thread priority without interrupting
2014-12-31T20:55:11 < qyx_> so don't use interrupts
2014-12-31T20:55:17 < qyx_> and do things arduino-style
2014-12-31T20:55:48 < decimad> Well, I see it as a hardware supported notification (callback) scheme
2014-12-31T20:56:10 < decimad> Not every notification is more important than the code I'm currently running though
2014-12-31T20:56:35 < decimad> That's my current view on it
2014-12-31T20:56:44 < qyx_> so mask it during execution of that important code
2014-12-31T20:56:49 < qyx_> also
2014-12-31T20:57:12 < qyx_> why are you doing such super-realtime tasks in your code?
2014-12-31T20:57:38 < qyx_> you shouldn't do timing sensitive things in code
2014-12-31T20:57:39 < decimad> qyx_: Well, that's what I thought a REALTIME os would be handling for me. To get the critical jobs done on time. But as it turns out, it doesn't ;)
2014-12-31T20:57:55 < qyx_> you are doing something wrong
2014-12-31T20:58:35 < ReadError> is there an easy way to suspend all interrupts then re-enable?
2014-12-31T20:58:50 < ReadError> w/o doing it completely manual for each
2014-12-31T20:59:42 < decimad> If I need to calculate some involved values within a microsecond (and can prove that the code itself meets those constraints) but can be interrupted by every ethernet packet and spi packet or you name it, I cannot satisfy the timing requirements.
2014-12-31T21:00:23 < decimad> That's what I thought the Realtime OS priority levels would guarantee me... but it doesn't. I have to do it manually ;)
2014-12-31T21:00:46 < decimad> It's an AnyTime OS ;)
2014-12-31T21:00:52 < englishman> Readerror what does it say in the datasheet? :)
2014-12-31T21:01:19 < ReadError> englishman i didnt look, i figured it was more a code thing which the datasheet doesnt cover

2014-12-31T21:01:52 < qyx_> theres an api for "kernel locking"

2014-12-31T21:03:42 < englishman> Cool
2014-12-31T21:03:48 < ReadError> englishman so does this exist or you be trolling me?
2014-12-31T21:03:48 < decimad> qyx_: Well, I can obviously roll my own locking and even lock the kernel and thereby lock all interrupts equal to or below SysTick priority
2014-12-31T21:04:06 < englishman> Theres your explanation, looks like
2014-12-31T21:05:06 < qyx_> wat
2014-12-31T21:05:28 < englishman> S-locked state I think is what ur looking for
2014-12-31T21:05:54 < decimad> qyx_: It's just I assumed thread priority levels would make some kind of strong guarantee, it turns out they only strictly put an order of user thread execution (not even on timing, since ISRs are out of control).
2014-12-31T21:06:10 < ReadError> englishman, but im not using chibios
2014-12-31T21:06:16 < englishman> I kno
2014-12-31T21:06:28 < qyx_> decimad: i pasted you a link which explains how to control interrupts
2014-12-31T21:06:38 < qyx_> in chibios
2014-12-31T21:11:02 < decimad> qyx_: Yes and I'm grateful, if it were not for these APIs I could also do the same by hand (using BASEPRI for example, which I guess is used behind the scene, or masking all interrupts or what not). I'm only thinking that there was sense for a different system, where threads and isrs live in a unified priority land :)
2014-12-31T21:13:20 < decimad> qyx_: But it is already helpful that you turned out my misconception on the system as it works. So thanks, that makes reasoning a lot easier.
2014-12-31T21:15:21 < qyx_> hopefully i haven't misconcepted you more
2014-12-31T21:21:53 < decimad> qyx_: I think the system is as it is because not all platforms even support isr preemption and isr priority levels... and then those that do might not support enough priority levels... other than that I would see no downsides unifying both. on stm32 one could also use the four unused priority bits for thread stuff I imagine ;)

2014-12-31T21:32:08 < PaulFertser> zyp: I do not understand when it might be really useful to have the same preemption priority but different subpriority, i.e. when grouping is useful?
2014-12-31T21:32:44 < PaulFertser> What's the practical usecase for that?
2014-12-31T21:33:16 < zyp> the most obvious that comes to mind is pendsv
2014-12-31T21:34:06 < zyp> hmm, no, wait, that doesn't make sense
2014-12-31T21:34:09 < PaulFertser> Please excuse me but I can't follow yet.
2014-12-31T21:34:19 < zyp> sorry, I was thinking of something different
2014-12-31T21:35:50 < zyp> say, can we reduce your question to «why is interrupt priorities useful if interrupts can't preempt other interrupts?»?
2014-12-31T21:35:54 < PaulFertser> afaict subgrouping affects the order of the isr when several of them are pending at the same time. But they can't preempt each other. When would be this arrangment needed is not something I can understand.
2014-12-31T21:35:58 < PaulFertser> Yes
2014-12-31T21:36:11 < PaulFertser> Well, no :)
2014-12-31T21:36:24 < zyp> why not?
2014-12-31T21:36:28 < PaulFertser> Here you always have a choice. So interrupts can preempt others if you choose to.
2014-12-31T21:36:42 < zyp> yes, unless you group all interrupts
2014-12-31T21:38:04 < zyp> the reason priorities are still useful without preemption is that you can have multiple interrupts go pending while one interrupt are processing, and the priority then determines which gets processed next
2014-12-31T21:38:20 < PaulFertser> Yes, by definition.
2014-12-31T21:38:51 < PaulFertser> But why would anyone choose that over using preemption and proper locking where needed?
2014-12-31T21:38:55 < zyp> and using pendsv for context switches is one of the cases where it's useful in practice
2014-12-31T21:40:58 < zyp> because then you can have multiple ISRs updating the ready-to-run state of threads and setting pendsv, and then pendsv executing last does the actual reschedule and context switch
2014-12-31T21:41:54 < PaulFertser> FreeRTOS manages without that...
2014-12-31T21:42:17 < zyp> sure
2014-12-31T21:43:38 < zyp> then you have stack conservation issues
2014-12-31T21:43:39 < PaulFertser> I mean that facility provides a complicated way to make a mess. Probably in some rare cases it can give a little bit of additional performance (by avoiding additional sw locking).
2014-12-31T21:44:09 < zyp> if you have stack-heavy ISRs, you may have a situation where one ISR is more important than another, but not enough to justify preempting it
2014-12-31T21:44:44 < zyp> preemption also wastes cycles on another set of stacking/unstacking, as opposed to interrupt chaining
2014-12-31T21:45:01 < PaulFertser> Hm, indeed.
2014-12-31T21:45:27 < zyp> and you do realize that many architectures doesn't allow interrupt preemption at all?
2014-12-31T21:45:39 < PaulFertser> Yes.
2014-12-31T21:46:10 < PaulFertser> On x86 that's the default behaviour iirc, apart from NMI or something.
2014-12-31T21:46:16 < zyp> cortex-m gives you a choice, you can have no preemption, full preemption, or a mix
2014-12-31T21:47:41 < zyp> and if you're not interested in a mix, do one or the other, I don't see how that is a problem
2014-12-31T21:48:46 < PaulFertser> It seems harder to estimate latencies when using subpriorities. I understand having a choice is nice, but I wanted to learn more about the topic.
2014-12-31T21:49:00 < PaulFertser> Thank you for the discussion indeed.
2014-12-31T21:49:49 < zyp> I don't see how it's harder at all, having multiple interrupts occurring will always give you variable latency regardless of whether you're having preemption or chaining
2014-12-31T21:50:46 < PaulFertser> All in all, I like FreeRTOS's model. You can have ISRs preempting anything but not calling FreeRTOS functions, you can have normal ISRs that can't preempt the "kernel" and use SendFromISR etc. And you can have collaborative multitasking (with yield) or yielding from a timer ISR regularly. And that's all clean and predictable.
2014-12-31T21:52:06 < zyp> «preempting anything» meaning even each other?
2014-12-31T21:52:21 < PaulFertser> However you want to arrange it.
2014-12-31T21:53:00 < zyp> you'd still be limited by hardware support for that
2014-12-31T21:53:10 < PaulFertser> Indeed
2014-12-31T21:53:54 < zyp> I imagine that on cortex-m there's a priority limit set for what can preempt the kernel or not
2014-12-31T21:54:11 < zyp> and then PRIMASK gets set to that limit when doing kernel stuff
2014-12-31T22:01:25 < PaulFertser> basepri, yes.
2014-12-31T22:02:34 < zyp> ah, right
2014-12-31T22:04:08 < decimad> That sounds cool... do you two have an opinion on the recent discussion?

2014-12-31T22:08:22 -!- emeb [~ericb@174-17-18-165.phnx.qwest.net] has quit [Ping timeout: 240 seconds]
2014-12-31T22:08:59 < zyp> can somebody summarize it for me?
2014-12-31T22:09:49 < zyp> Laurenceb_ once wrote some code with tasks in long-running low-priority ISRs
2014-12-31T22:10:12 < qyx_> thats probably what decimad wants
2014-12-31T22:10:23 < zyp> I'm not sure what the conclusion of that story was, but it sounded like a pretty bad idea to me at the time
2014-12-31T22:11:03 < decimad> zyp: I was just suggesting to have threads and isrs live in the same priority "namespace"
2014-12-31T22:12:14 < zyp> why would you want to have interrupts with lower priority than any threads?
2014-12-31T22:12:31 < qyx_> thats the point of failure
2014-12-31T22:12:53 < qyx_> he wants to run strictly realtime tasks in threads
2014-12-31T22:13:05 < qyx_> without interrupting them by interrupts
2014-12-31T22:13:15 < zyp> though, unifying the priority namespace is easy enough, just set BASEPRI to the current thread level on context switch, then it can only be interrupted by higher level interrupts
2014-12-31T22:13:52 < zyp> I just don't understand which ISRs that can be lower level than any threads :)
2014-12-31T22:14:31 < decimad> communication packet arrival notifications or something
2014-12-31T22:14:46 < zyp> so in practice that'll result in BASEPRI being lower than any treads all the time, which means it doesn't do anything different from being set to FF
2014-12-31T22:16:29 < decimad> I mean I have no current thing in mind, but I was thinking about timing, RT and stuff and then this popped up. Nothing in a Realtime OS is actually realtime if those two priority realms are not unified. If you need to resort to user handling and switching on and off stuff, then the Realtime OS has handled only the non-realtime stuff for you
2014-12-31T22:17:03 < zyp> decimad, I'd say a better approach to that would be to schedule the communication thread to handle it, then temporarily disable the interrupt
2014-12-31T22:17:20 < zyp> then enable it again once the communication thread goes to sleep
2014-12-31T22:17:41 < decimad> zyp: Well, I only set events in my isr routines, still the thread that was running was interrupted and a stackframe was pushed and popped and all
2014-12-31T22:18:29 < zyp> sure
2014-12-31T22:19:17 < decimad> So I see no downsides of unifying the stuff... you can get either way that way
2014-12-31T22:20:40 < zyp> well, what you just describes sounds like you have time for no interrupts at all
2014-12-31T22:21:04 < zyp> which makes the priority itself a moot point
2014-12-31T22:22:06 < zyp> also, you're mixing up the decision factor for which thread to run with the decision factor for what can interrupt a thread
2014-12-31T22:23:22 < zyp> what about code pieces that's like «we don't have to run this thing right now, but when it runs we can't have anything interrupting it»?
2014-12-31T22:23:35 < zyp> like bitbanging some kind of data packet
2014-12-31T22:23:48 < zyp> doesn't matter if you delay the packet a bit, as long as you get the bit timings right

2014-12-31T22:25:02 < decimad> zyp: Well, my current understanding is, you can only do one thing with hard realtime demands (time-aligned stuff counting as one), so if bitbanging a packet is what you want to spend it on
2014-12-31T22:26:23 < decimad> So all my reasoning is on the best effort space that is left after hard realtime stuff. Maybe if you finish this or that earlier, you might improve system efficiency
2014-12-31T22:26:38 < decimad> I thought that's where the OS would help me
2014-12-31T22:27:09 < zyp> then I'd say your current understanding is wrong
2014-12-31T22:28:55 < decimad> ............... wait for it ....... :)
2014-12-31T22:29:43 < decimad> Well, if your hard realtime demands allow the longest non interruptable sequence to finish additionally to your job, then ok ;)

2014-12-31T22:35:33 < zyp> what would be the value of all the realtime stuff if it were only good for running a single task?
2014-12-31T22:35:55 < zyp> if you only had a single real time task to run, you'd just block everything else while running it and be fine
2014-12-31T22:36:57 < zyp> realtime is about bounded latencies and hard realtime is about being able to prove that the bounds are true
2014-12-31T22:37:44 < decimad> zyp: That's what I'm currently questioning, yes. For one, the scheduling on the systems I currently know is done on a time granularity, often time ticks, so that aligns stuff in itself. Which makes those things realtime-able. Howerver ISRs can break that externally. (Think DDoSing for isr blocking or something)
2014-12-31T22:39:09 < zyp> are you sure you're not confusing realtime with low latency?
2014-12-31T22:39:15 < decimad> So you need to resort to "manual" intervention. I thought that might be unified to some part if you'd unify the priorities... which might very well be not the case...
2014-12-31T22:39:21 < zyp> bounded latency and low latency are different things
2014-12-31T22:39:36 < decimad> zyp: Well how do you bound the latency if every isr can block the whole system?
2014-12-31T22:40:44 < zyp> of course the run time of the isr have to be bounded too
2014-12-31T22:40:59 < decimad> Even if it is only doing very tiny work, if the system is hammered with it, you need to resort to manual deactivation
2014-12-31T22:41:01 < zyp> it's part of calculating the proof
2014-12-31T22:42:26 < zyp> also, there's a term for that
2014-12-31T22:42:27 < zyp> http://en.wikipedia.org/wiki/Interrupt_storm
2014-12-31T22:43:12 < decimad> And IF you're doing this prioritizing manually, these interrupts are asynchronous, so it can get complicated to get enabling and disabling correct and stay in synch
2014-12-31T22:43:45 < decimad> thanks for that pointer!
2014-12-31T22:44:54 < PaulFertser> decimad: if your interrupt has lower priority than the timer interrupt that passes control to the scheduler, then you'll still have bounded latencies for your RTOS tasks.
2014-12-31T22:45:30 < decimad> PaulFertser: Well the moment the scheduler scheduled the isrs will be chaine called, no?
2014-12-31T22:45:37 < PaulFertser> Because not evey isr can block the whole system on an architecture that allows interrupt preemption.
2014-12-31T22:46:00 < PaulFertser> decimad: you're supposed to not let that happen by arranging priorities appropriately.
2014-12-31T22:47:46 < decimad> PaulFertser: So there we have it, I need to align my ISR priorities with the OS priorities and then at times I need to manually toggle base priorities within thread code. I was just thinking that unifying would remove one cause of "inhomogenous" code
2014-12-31T22:48:57 < zyp> a real time scheduler doesn't operate with priorities, it operates with deadlines
2014-12-31T22:49:04 < decimad> PaulFertser: Although, still, when the Scheduler interrupt rescheduled, it will leave interrupt mode and then any ISR, no matter how low the priority is, it will be entered
2014-12-31T22:49:23 < zyp> decimad, see http://en.wikipedia.org/wiki/Earliest_deadline_first_scheduling
2014-12-31T22:51:39 < decimad> zyp: I think there are numerous scheduling algorithms, is this the only one applicable to RT? Also it doesn't seem as if ChibiOS-RT would use it. I think it schedules whatever thread with highest priority is ready, and then round-robing for threads of equal priority
2014-12-31T22:51:58 < decimad> robin
2014-12-31T22:52:31 < zyp> yes, but that by itself is not a realtime construct

2014-12-31T22:54:24 < PaulFertser> decimad: probably what you imply is that you'd like and interrupt handler to become a temporary-living RTOS task with the priority you set it?
2014-12-31T22:55:07 < decimad> PaulFertser: Well, I would like to think of interrupts as threads that are idling all the time and waiting for an event that is raised by hardware :)
2014-12-31T22:56:33 < zyp> that's a bad way to think about them
2014-12-31T22:58:21 < zyp> ISRs are functions that starts, runs and ends, before being able to be started again
2014-12-31T22:58:46 < decimad> how is that different from the usual event driven thread loop?
2014-12-31T22:59:31 < zyp> in that threads can be paused and resumed at any point
2014-12-31T22:59:56 < decimad> Well ISR's can be too on a prioritized system
2014-12-31T23:00:50 < PaulFertser> decimad: you can imitate that by having dedicated threads sleeping on a mutex/semaphore/queue, and ISRs producing the events.
2014-12-31T23:00:56 < zyp> in a sanely designed system, you can't sleep() in an ISR and allow other code to run in the mean time
2014-12-31T23:01:37 < decimad> Well, that's just because you happen to "see" them differently
2014-12-31T23:01:59 < zyp> I see them differently because they are different
2014-12-31T23:02:43 < PaulFertser> Well, you can wait in a thread waiting for an event produced by another thread. Why not wait in a thread waiting for a hardware event, how is it different?
2014-12-31T23:04:40 < decimad> There's an event and there's code to be executed once that event happened, the only difference that sets them apart is who generates the event for me. If you're idling in a thread reasoably then the OS will add stack magic, as does the MCU for hardware events
2014-12-31T23:06:25 < zyp> there's a pretty significant difference between being in interrupt context and being in thread context in what your code is allowed to do
2014-12-31T23:06:27 < PaulFertser> BTW, one of the alternative to EDF is https://en.wikipedia.org/wiki/Rate-monotonic_scheduling

2014-12-31T23:07:26 < PaulFertser> You can use RMA and prove some facts regarding ChibiOS or FreeRTOS if you need.
2014-12-31T23:12:07 < ReadError> is there a decent "from noob to beast" guide on ChibiOS or RTOS in general ?
2014-12-31T23:13:48 < PaulFertser> Andrew Tannenbaum's book probably?
2014-12-31T23:13:59 < PaulFertser> For me FreeRTOS docs were sufficient.
2014-12-31T23:15:35 < PaulFertser> Well, I do not have a real clue, never done a RTOS-related proof or used an EDF system.
2014-12-31T23:15:45 < PaulFertser> But I think I can do that if needed.
2014-12-31T23:17:10 < Laurenceb_> someone mentioned me?!
2014-12-31T23:17:37 < Laurenceb_> lol, yeah for like 2 tasks and simple stuff maybe low priority isr is useful imo
2014-12-31T23:18:09 < Laurenceb_> but in fact my solution wasnt very nice, if i did it again id use chibios for the same job, its more flexible
2014-12-31T23:19:45 < decimad> Laurenceb_: Well, I'm not saying that it's super useful everywhere, but where's the harm in aligning those two priority systems and have it for free if you come accross an occasion that might benefit from it
2014-12-31T23:19:45 < PaulFertser> decimad: for many current real-life practical purposes I'd say Xenomai is a fine system. Folks ("LinuxCNC") manage to get decent results with it even on raspberrypi.
2014-12-31T23:21:40 < Laurenceb_> also, many microcontroller problems can be solved with interrupt driven state machines
2014-12-31T23:21:48 < Laurenceb_> more work, but usually runs very fast
2014-12-31T23:22:35 < decimad> PaulFertser: I don't understand this. My dad's running a small handcrafted mill with linuxCnc and there they state they're using RTLinux (which seems abandoned to me)
2014-12-31T23:23:21 < PaulFertser> decimad: they switched to Xenomai I think.
2014-12-31T23:24:14 < decimad> PaulFertser: Then I must have stumbled across outdated documentations, okay. I'm no expert with that. I only know that he had troubles keeping the latency low
2014-12-31T23:26:36 < PaulFertser> decimad: e.g. http://linuxcnc.mah.priv.at/rpi/rpi-rtperf.html
2014-12-31T23:32:12 < decimad> PaulFertser: I somehow find this software driven gpio toggling strange for controlling motors I must admit
