2013-11-01T04:37:35 < efuentes> Hi Everyone!
2013-11-01T04:38:15 < efuentes> having a USB problem and was hoping someone could help me out
2013-11-01T04:38:28 < efuentes> I'm using the f4 discovery board
2013-11-01T04:38:41 < efuentes> and I'm trying to write my own USB stack to figure out how the peripheral works
2013-11-01T04:39:14 < efuentes> I've gotten as far as receiving the setup packet and trying to send the device descriptor
2013-11-01T04:39:33 < efuentes> It doesn't seem like the device descriptor is getting sent out however...
2013-11-01T04:40:14 < efuentes> I connected the board to a linux computer and in the response to that setup packet
2013-11-01T04:40:27 < efuentes> It says that it is a "malformed packet"
2013-11-01T04:41:02 < efuentes> I connected a logic analyzer and it turns out that the USB peripheral is NAKing every IN token
2013-11-01T04:41:45 < prattmic> efuentes: I wrote a USB stack about a year ago, that was an experience
2013-11-01T04:41:55 < efuentes> I've looked at the USB stacks for ChibiOS and the ST peripheral library and I can't seem to find what I'm missing
2013-11-01T04:42:14 < efuentes> prattmic: tell me about it...
2013-11-01T04:42:39 < prattmic> efuentes: I didn't really understand how USB worked when I got started...
2013-11-01T04:42:51 < efuentes> same
2013-11-01T04:42:53 < prattmic> I recall having a similar issue, but can't recall the fix
2013-11-01T04:43:18 < efuentes> do you have a copy that I can look at?
2013-11-01T04:43:27 < efuentes> the ST one is pretty shitty...
2013-11-01T04:43:31 < prattmic> efuentes: https://github.com/prattmic/F4OS/tree/master/arch/armv7m/chip/stm32f40x/dev/hw/usb
2013-11-01T04:43:40 < prattmic> It is pretty bad, though
2013-11-01T04:43:54 < prattmic> Probably some of the ugliest code in my RTOS, to be honest...
2013-11-01T04:44:00 < efuentes> well it's another datapoint
2013-11-01T04:44:08 < prattmic> I finally got it working and didn't really want to touch it :)
2013-11-01T04:44:12 < efuentes> haha
2013-11-01T04:44:18 < efuentes> The chibios one isn't bad
2013-11-01T04:44:28 < efuentes> it's just a really complicated peripheral
2013-11-01T04:46:06 < prattmic> I do some set/clear NAK around here: https://github.com/prattmic/F4OS/blob/master/arch/armv7m/chip/stm32f40x/dev/hw/usb/usbdev_core.c#L90
2013-11-01T04:47:45 < efuentes> int is an int32?
2013-11-01T04:47:59 < prattmic> yes
2013-11-01T04:48:21 < efuentes> okay
2013-11-01T04:51:22 < efuentes> so one difference I'm noticing is that you wait until the endpoint becomes disabled before re enabling it
2013-11-01T04:51:34 < efuentes> I had noticed that something the endpoint is enabled when I try to send something
2013-11-01T04:51:40 < efuentes> but I didn't think much of it
2013-11-01T04:51:45 < efuentes> I'll add that check
2013-11-01T04:52:06 < efuentes> where exactly is it that you are writing to the FIFO
2013-11-01T04:52:11 < efuentes> is it line 65
2013-11-01T04:52:18 < efuentes> ep->tx.buf?
2013-11-01T04:53:37 < prattmic> No, that is my own buffer.  The FIFO is actually written in the TX FIFO empty interrupt, IIRC, which is why 129 enables the interrupt
2013-11-01T04:53:49 < efuentes> okay
2013-11-01T04:54:05 < efuentes> that's the same approach the other two stacks I looked at took as well
2013-11-01T04:54:25 < efuentes> I must say
2013-11-01T04:54:29 < efuentes> it's pretty clean :)
2013-11-01T04:54:34 < efuentes> as ugly as usb is
2013-11-01T04:54:55 < prattmic> I believe that is usbdev_data_in()
2013-11-01T04:56:27 < prattmic> If you really want to see what is going on, you can flash the OS to your discovery board :)

2013-11-01T04:56:55 < prattmic> There are USB debug prints that can be enabled, but it can get unhappy when the UART can't keep up with the printing
2013-11-01T04:57:06 < efuentes> yeah...
2013-11-01T04:57:18 < efuentes> I've connected a small OLED display
2013-11-01T04:57:26 < efuentes> that gets updated in main
2013-11-01T04:57:38 < efuentes> it's been alright so far
2013-11-01T04:57:53 < prattmic> Sounds a bit slow...
2013-11-01T04:58:01 < efuentes> well I'm not printing much :)
2013-11-01T04:58:12 < efuentes> just the value of registers at certain points
2013-11-01T04:58:25 < dongs> < efuentes> I connected the board to a linux computer
2013-11-01T04:58:28 < dongs> i just found your problem
2013-11-01T04:58:37 < prattmic> Good thing we have JTAG, I wouldn't have survived without gdb
2013-11-01T04:59:04 < efuentes> dongs: I use what I can
2013-11-01T04:59:10 < efuentes> developing on a mac
2013-11-01T04:59:22 < efuentes> didn't have much luck getting wireshark up and running on w7
2013-11-01T04:59:26 < dongs> seems to be a common problem.
2013-11-01T04:59:37 < dongs> trying to use all this niche garbage like lunix, mac , etc
2013-11-01T04:59:42 < prattmic> dongs: On the contrary, I wouldn't want to develop in Windows
2013-11-01T04:59:49 < dongs> sorry to hear that.
2013-11-01T04:59:57 < dongs> i guess you like typing mile-long command lines into a black screen
2013-11-01T05:00:04 < efuentes> haha
2013-11-01T05:00:18 < efuentes> I was about to ask what you use for a terminal
2013-11-01T05:00:26 < efuentes> let me guess then dongs
2013-11-01T05:00:30 < efuentes> you use eclipse?
2013-11-01T05:00:41 < dongs> no, i like getting things done
2013-11-01T05:01:25 < efuentes> at least we can agree on that :)
2013-11-01T05:01:31 < prattmic> dongs: I don't mind, though usually it is just `make` or `stm32-gdb`
2013-11-01T05:02:00 < prattmic> I certainly appreciate the power my shell provides

2013-11-01T05:38:02 < efuentes> prattmic that was it
2013-11-01T05:38:13 < efuentes> waiting for the endpoint the be disabled before re enabling
2013-11-01T05:38:17 < efuentes> which now that I think about it
2013-11-01T05:38:20 < efuentes> kinda makes sense

2013-11-01T05:38:30 < prattmic> efuentes: Nice.  Glad you figured it out
2013-11-01T05:43:20 < prattmic> I remember doing the same thing; looking over other implementations trying to figure out what they did that I didn't
2013-11-01T05:50:58 < efuentes> yeah...
2013-11-01T05:51:26 < efuentes> I was getting to the point where I was considering dumping the values of each register and comparing across different stacks
2013-11-01T05:51:38 < efuentes> but... timing matters... alot...
2013-11-01T05:52:29 < prattmic> I actually did that once.  I basically rewrote a peripheral driver at one point, and broke it.  I actually dumped the register values before and after the change to see the difference
2013-11-01T05:52:58 < prattmic> In the end, I think it did end up being some timing/ordering problem, though...

2013-11-01T08:45:12 < emeb_mac> If I had a chance of making that back on these projects I'd consider it.
2013-11-01T08:46:55 < emeb_mac> I dunno - it's sort of comforting.

2013-11-01T11:54:59 < trepidaciousMBR> What's the best way to insert a noop using GCC?
2013-11-01T11:58:06 < DanteA> asm()
2013-11-01T12:00:25 < trepidaciousMBR> Is this ok? asm volatile("mov r0, r0");
2013-11-01T12:00:45 < trepidaciousMBR> There's a page here that is super helpful, but doesn't actual explicitly say that this form is bullet-proof: http://www.ethernut.de/en/documents/arm-inline-asm.html
2013-11-01T12:09:50 < zyp> asm volatile("nop");
2013-11-01T12:10:56 < zyp> also, what are you planning to use it for?
2013-11-01T12:11:15 < zyp> remember that the timing of a nop is not deterministic

2013-11-01T12:11:29 < zyp> so you don't really want to use it for delay loops
2013-11-01T12:11:38 < zyp> use a timer instead if that's your goal
2013-11-01T12:16:27 < trepidaciousMBR> zyp: I was looking at a problem with USB initialisation on the 429, it seems to need a very small delay, and I was wondering how short a delay would work
2013-11-01T12:16:47 < trepidaciousMBR> zyp: I got down past what would make sense for the normal delays, so I was wondering if a few nops would do it

2013-11-01T12:25:23 < zyp> heh
2013-11-01T12:26:20 < zyp> does it really matter whether you have a delay of a microsecond or a millisecond? the practical difference would be pretty irrelevant either way
2013-11-01T12:32:24 < trepidaciousMBR> Yup, I would be fine with a millisecond but it's interesting for working out what is wrong with the driver
2013-11-01T12:32:50 < trepidaciousMBR> I still have no idea - it's in ChibiOS so hopefully Giovanni will work it out :)
2013-11-01T12:44:32 < Steffanx> the y revision of the f429 was the 'good' one not?
2013-11-01T12:44:50 < trepidaciousMBR> Yup
2013-11-01T12:45:00 < Steffanx> Great.
2013-11-01T12:45:48 < trepidaciousMBR> Seems to be what everyone has, hopefully the A never made it outside ST

2013-11-01T18:05:37 < knielsen> Robint91: If you check figure 25/26 in section 9.3.1 in the product specification, you can see that the FSMC is accessible to the DMA controller (just the 64kB internal SRAM is not)
2013-11-01T18:06:17 < knielsen> So it should just be a memory-to-memory dma transfer
2013-11-01T18:07:44 < Robint91> knielsen, yeah, I was thinking that is whould be possible
2013-11-01T18:07:55 < Robint91> but the NAND flash isn't just byte addressable
2013-11-01T18:07:57 < Robint91> so
2013-11-01T18:08:01 < knielsen> The FSMC is rather nice to have I think, I recently made a small board with external SRAM though I didn't really do much with it yet. The price of SRAM is a bit high though, and I did not find any SDRAM in a hobbyist-friendly package...

2013-11-01T18:19:37 < knielsen> I suppose one could try doing the command/address setup with the cpu, and then setup a DMA transfer to do the byte-by-byte read of the page

2013-11-01T18:41:07 < fbs> do i need to reset the DMA address after each dma transfer? I want to spi send a buffer as slave
2013-11-01T18:42:29 < gxti> fbs: afaik the address is never modified, but it's still good practice to assume the worst
2013-11-01T18:44:25 < fbs> for some reason only the first transfer works

2013-11-02T03:48:53 < efuentes> Serial Audio Interface I think
2013-11-02T03:48:57 < Tectu> is that some new 429 shit or did the 407 already have that as well
2013-11-02T03:49:03 < efuentes> pretty sure it's new
2013-11-02T03:49:05 < Tectu> nope, it's some special PLL
2013-11-02T03:49:17 < Tectu> used for the LTDC (LCD TFT Display Controller)
2013-11-02T03:49:18 < dongs> yeah its pll for the SAI shit.
2013-11-02T03:49:29 < Tectu> do you know what SAI is, dongs?
2013-11-02T03:49:31 < fbs> -O0 code is horrible to read, im not even going to try and figure out what i going wrong
2013-11-02T03:50:05 < dongs> gcc sounds like total shit
2013-11-02T03:50:09 < dongs> glad im using a real compiler.
2013-11-02T03:50:16 < fbs> like?
2013-11-02T03:50:20 < dongs> armcc
2013-11-02T03:50:21 < GargantuaSauce_> are you using -Wall and -Wextra? most undefined behaviours that result in fucking stuff up like that result in warnings
2013-11-02T03:51:08 < fbs> GargantuaSauce_: i got a 'set_time()' and 'set_date()' function, if i use those it work, if i call them from 'set_datetime()' it works. but if i copy their bodies into datetime it just fails
2013-11-02T03:51:51 < dongs> sounds like youre fucking shit upo
2013-11-02T03:53:48 < fbs> :p
2013-11-02T03:54:53 < GargantuaSauce_> really though check for warnings. especially things like calling an undeclared function
2013-11-02T03:55:08 < GargantuaSauce_> doesn't have to be that function
2013-11-02T03:55:24 < GargantuaSauce_> could be further up the stack and it could have been asymptomatic until now
2013-11-02T03:55:28 < Tectu> DAFUQ IS PLLSAI
2013-11-02T03:56:09 < GargantuaSauce_> i am going to take a wild guess and say it's for generating the pixel clock
2013-11-02T03:56:21 < Tectu> exactly
2013-11-02T03:56:27 < Tectu> do you know what SAI stands for?
2013-11-02T03:57:28 < GargantuaSauce_> standard asshole interface
2013-11-02T03:58:59 < GargantuaSauce_> yeah according to my googles efuentes is correct, and it just happens to be used for the display controller too?
2013-11-02T04:01:23 < ds2> standard? is that an ISO or ANSI standard?
2013-11-02T04:01:34 < GargantuaSauce_> ieee
2013-11-02T04:02:15 < GargantuaSauce_> they have the largest body of asshole expertise
2013-11-02T04:02:21 < Tectu> lol
2013-11-02T04:04:06 < ds2> shouldn't that be the USAI interface?
2013-11-02T04:04:52 < GargantuaSauce_> that one's deprecated
2013-11-02T04:05:10 < Tectu> thought they made it 3.0
2013-11-02T04:09:14 < fbs> hmm interesting
2013-11-02T04:09:34 < fbs> RTCDS.RTC_Year = (y%100);
2013-11-02T04:10:03 < fbs> if i compile that with -O0 i get 25 as year, but printf("%d", y%100) still gives 13, with -Os its fine
2013-11-02T04:10:42 < GargantuaSauce_> what is the type of y
2013-11-02T04:11:01 < fbs> uint16_t
2013-11-02T04:16:34 < fbs> (gdb) p RTCDS.RTC_Year

2013-11-02T04:49:06 < efuentes> hi chris
2013-11-02T04:49:08 < fbs> its the not setting of 'RTC_WeekDay'
2013-11-02T04:49:16 < efuentes> I have pretty similar code
2013-11-02T04:49:38 < efuentes> what is in USART_SendData?
2013-11-02T04:49:39 < chris1seto> Hey efuentes
2013-11-02T04:49:48 < efuentes> is it just USART1->DR = ch?
2013-11-02T04:49:48 < fbs> if i set rtc_weekday its fine
2013-11-02T04:50:04 < chris1seto> It's actually the stdperiph driver from STM
2013-11-02T04:50:19 < chris1seto> Any function that is not defined in that file directly is from the STM libs
2013-11-02T04:50:31 < efuentes> we don't all use the std libs ;)
2013-11-02T04:50:43 < chris1seto> Hehe, ok hold on, I'll copy it
2013-11-02T04:50:45 < efuentes> let me pull the file up
2013-11-02T04:51:23 < chris1seto>  USARTx->DR = (Data & (uint16_t)0x01FF);
2013-11-02T04:51:36 < chris1seto> That's all that's in it other than some assert statments
2013-11-02T04:51:39 < efuentes> yup
2013-11-02T04:51:52 < chris1seto> line 584 is where the definition starts
2013-11-02T04:52:07 < fbs> Looks like i somehow end up with 255 or similar in the stackspace of WeekDay, with -Os there is 0..7 in that spot so everything is fine
2013-11-02T04:52:45 < efuentes> so is it an initialization issue then?
2013-11-02T04:52:57 < chris1seto> Yep
2013-11-02T04:52:58 < chris1seto> Looks like it
2013-11-02T04:53:14 < chris1seto> After that first char is dropped, everything is A-ok
2013-11-02T04:53:41 < chris1seto> I'm assuming there isa flag that I should wait on, but I tried a delday between init and send, and there was no change
2013-11-02T04:53:58 < fbs> kinda lame, they have a assert but they just continue if its invalid
2013-11-02T04:54:06 < fbs>   assert_param(IS_RTC_WEEKDAY(RTC_DateStruct->RTC_WeekDay));
2013-11-02T04:54:58 < efuentes> fbs, I've learned not to trust their code :)
2013-11-02T04:55:15 < efuentes> most of the peripherals aren't very complicated
2013-11-02T04:55:43 < chris1seto> I sure couldn't find any....
2013-11-02T04:55:43 < chris1seto> Are there actually any docs for the STM libs?
2013-11-02T04:55:53 < efuentes> I don't think so
2013-11-02T04:55:54 < fbs> docs are generated from the sourcecode
2013-11-02T04:56:01 < efuentes> so here are things I would try chris
2013-11-02T04:56:07 < efuentes> I have something similar to what you have
2013-11-02T04:56:16 < fbs> i got some usart send code
2013-11-02T04:56:28 < efuentes> only difference is that I wait before I put the char in the data register
2013-11-02T04:56:39 < chris1seto> What are you using to delay?
2013-11-02T04:56:49 < efuentes> and actually
2013-11-02T04:56:50 < fbs>       while (USART_GetFlagStatus(STDOUT_USART, USART_FLAG_TC) == RESET);
2013-11-02T04:56:51 < fbs>       USART_SendData(STDOUT_USART, (uint8_t) * ptr++);
2013-11-02T04:56:57 < efuentes> Here's what I've got
2013-11-02T04:57:29 < efuentes> while(!(USART->SR & USART_SR_TXE));
2013-11-02T04:57:38 < efuentes> USART->DR = c;
2013-11-02T04:57:41 < efuentes> so
2013-11-02T04:57:50 < efuentes> instead of checking for the transmission complete flag
2013-11-02T04:58:00 < efuentes> try checking for the tx empty flag
2013-11-02T04:58:12 < efuentes> and more the wait to before the call to USART_SendData
2013-11-02T04:58:16 < efuentes> make sense?

2013-11-02T05:12:34 < fbs> lol, stdlib asserts make add 14k
2013-11-02T05:14:19 < dongs> stdlib asserts are pretty useless anyway
2013-11-02T05:14:31 < fbs> anyone got tricks to parse map files (-Wl,-Map=..) files to find big functions?
2013-11-02T05:14:41 < fbs> yea they are
2013-11-02T05:14:41 < dongs> um
2013-11-02T05:14:44 < dongs> just look at them?
2013-11-02T05:14:47 < efuentes> yeah...
2013-11-02T05:14:54 < efuentes> I would say the same thing
2013-11-02T05:14:57 < fbs> this mapfile is 180KB
2013-11-02T05:14:57 < dongs> duno what map shit gcc makes but stuff from armcc is quite readable

2013-11-02T05:15:46 < chris1seto> Anyway, efuentes, your fix worked. Thanks!!
2013-11-02T05:15:47 < efuentes> chris1seto
2013-11-02T05:15:50 < efuentes> cool
2013-11-02T05:16:08 < efuentes> yeah sorry fbs...
2013-11-02T05:16:13 < efuentes> I'm not going to look through that...
2013-11-02T05:16:20 < fbs> :p
2013-11-02T05:16:38 < fbs> guess is should write a simple parser for it
2013-11-02T05:16:45 < chris1seto> So, I'm oretty new with these chips, but if you guys aren't using the STM libs, are you using some kind of abstraction layer or library?
2013-11-02T05:16:58 < chris1seto> Or are you just writting your own register level libs?
2013-11-02T05:17:24 < efuentes> depends
2013-11-02T05:17:32 < efuentes> I write my own libs for work
2013-11-02T05:17:59 < efuentes> I'll use chibios for the more complicated ones
2013-11-02T05:18:03 < efuentes> but they aren't perfect either
2013-11-02T05:18:11 < efuentes> definitely better than the st libs though
2013-11-02T05:18:28 < chris1seto> It's kind of odd that STM doesn't have a really nice, straightforward set of libs
2013-11-02T05:18:47 < efuentes> people who have the money pay for better ones
2013-11-02T05:19:05 < efuentes> but like I said
2013-11-02T05:19:15 < dongs> keil added some newfag abstraction layer/hal stuff in v5
2013-11-02T05:19:16 < efuentes> most of the peripherals are pretty straightforward
2013-11-02T05:19:23 < dongs> i tried it for 30 seconds and went back to st's libs
2013-11-02T05:19:37 < dongs> i've written my own stuff for GPIO
2013-11-02T05:19:41 < dongs> since ST one was supoer bloated
2013-11-02T05:19:46 < efuentes> yeah...
2013-11-02T05:19:52 < efuentes> I just have a header file
2013-11-02T05:19:52 < dongs> but other shit is just meh,,, not worth the effort to rewrite
2013-11-02T05:20:13 < efuentes> I've written almost everything but the Ethernet
2013-11-02T05:20:15 < efuentes> and DCMI

2013-11-02T09:42:42 < GargantuaSauce_> just a couple days ago
2013-11-02T09:43:38 < madist> is that the exact string you're getting ?
2013-11-02T09:44:21 < madist> as in, is it a repeating pattern ?
2013-11-02T09:53:16 < GargantuaSauce_> yeah, though some other sanity checks are failing so i'm quite sure i'm just doing something stupid
2013-11-02T10:11:15 < GargantuaSauce_> .....i replaced the nordic module and it works now

2013-11-02T11:39:14 < ouah> is there is really no way to disable the jtag by HW (except with the readout level 2)?
2013-11-02T11:39:28 < ouah> This somewhat dooms five pins in the MCU.
2013-11-02T11:47:46 < dongs> ?
2013-11-02T11:47:56 < dongs> which cortex?
2013-11-02T11:48:04 < dongs> you can jsut use them as GPIO by changing their function.
2013-11-02T11:49:30 < ouah> dongs: this is by SW
2013-11-02T11:49:46 < dongs> ? i dont understand waht youre trying to do then
2013-11-02T11:50:10 < jpa-> only a problem during boot.. but i wonder if the pins are actually floating if you don't mess with JTMS
2013-11-02T11:50:10 < ouah> dongs: by HW means to startup with no JTAG and that it is to startup with JTAGS pins as floating inputs
2013-11-02T11:50:27 < jpa-> *all* GPIO starts as floating inputs anyway..
2013-11-02T11:50:31 < dongs> well, dont use htem for anything important
2013-11-02T11:50:34 < jpa-> ah
2013-11-02T11:50:39 < ouah> jpa-: not the GPIO pins on the JTAG connector
2013-11-02T11:50:47 < jpa-> yeah, misread your line
2013-11-02T11:50:59 < dongs> for example im using SWO as regular gpio trash for a buzzer or something
2013-11-02T11:51:07 < dongs> havent had any issues
2013-11-02T11:51:22 < dongs> swo is jtms i think?
2013-11-02T11:51:32 < ouah> they could have come with a fuse which disable the JTAG pins but still keep the SWD pins enabled
2013-11-02T11:51:44 < dongs> ouah: they have it in software....
2013-11-02T11:52:18 < ouah> dongs: which is nearly irrelevant if it is only in software
2013-11-02T11:52:26 < jpa-> JTDI should be floating, NJTRST also, any sane person has atleast SWD connected to debugger anyway.. only JTDO is a bit disconvenient
2013-11-02T11:52:31 < ouah> dongs: you have some pull-up enabled for some time
2013-11-02T11:52:42 < dongs> ouah: put disable code in reset vector then
2013-11-02T11:52:47 < dongs> its like 3 instructions to disable jtag
2013-11-02T11:53:40 < jpa-> there is going to be some capacitive glitches on IO pins at boot anyway - a few microseconds of >50kohm pull-up shouldn't be much different
2013-11-02T11:54:03 < jpa-> but who cares about 5 GPIO anyway when you usually have atleast 30 and just pick a bigger one if you need more
2013-11-02T11:54:04 < dongs> ^
2013-11-02T11:54:31 < ouah> GPIO is money
2013-11-02T11:54:37 < jpa-> and like dongs says, perfectly usable for functions that are not critical at boot
2013-11-02T11:55:12 < dongs> i doubt you have *all* IO used to the point where retasking one of htem into something off jtag that can be ignored until reset and then configured there
2013-11-02T11:55:19 < dongs> is impossible
2013-11-02T11:55:19 < ouah> jpa-: yes, but still they could have come up with a disable fuse. AVR xmega does that for example.
2013-11-02T11:55:33 < dongs> the difference is nobody uses avr xmegta.
2013-11-02T11:55:35 < jpa-> ouah: that would enable bricking the device
2013-11-02T11:55:52 < dongs> atmel is good at bricking devices
2013-11-02T11:56:09 < dongs> configure their trash for ext xtal mode and don't provide a clock = fucked

2013-11-02T19:02:40 < PaulFertser> jpa-: well, he developes for megas and xmegas and targets arduino boards, so he's using the boards at least while developing; also, why would someone write such complicated code for arduino, do you think he's doing that just for profit?
2013-11-02T19:18:31 < Laurenceb__> is that on xmega or regular avr?
2013-11-02T19:18:34 < Laurenceb__> seems very fast
2013-11-02T19:19:25 < PaulFertser> He says he implemented the driver for both, using some "xmem" interface on xmega and gpio bitbanging on regular mega.
2013-11-02T19:19:35 < Laurenceb__> bet the video is xmega
2013-11-02T19:21:36 < Steffan-> No, xmem is regular AVR (atmega128+ or so )
2013-11-02T19:21:39 < Laurenceb__> stm32plus looks interesting
2013-11-02T19:21:42 < Laurenceb__> ah
2013-11-02T19:21:50 < Laurenceb__> but ... why??
2013-11-02T19:22:10 < Laurenceb__> all the features can be done with other code

2013-11-02T19:23:03 < PaulFertser> c++ can generate efficient purpose-specific code thanks to metaprogramming, I guess that's why he wants using it.

2013-11-02T19:41:33 < efuentes> what's the difference between lwip and uip?
2013-11-02T19:42:30 < Laurenceb__> lol stm32plus is fatfs with c++ wrappers
2013-11-02T19:42:39 < Laurenceb__>  - for the fat32
2013-11-02T19:43:03 < PaulFertser> efuentes: for me the killer difference was that uip needs ack for every tcp segment before it sends the next, so talking to windows it takes 200ms for each single packet (as windows persists on deferring acks).
2013-11-02T19:43:52 < PaulFertser> efuentes: also, uip is not developed anymore, all the code was absorbed by contikios or something like that.
2013-11-02T19:44:21 < efuentes> Oh I read about contiki a few months back
2013-11-02T19:44:36 < efuentes> I took a quick look at it...
2013-11-02T19:44:49 < efuentes> I don't think I'm a fan of protothreading
2013-11-02T19:44:53 < efuentes> or whatever it was called
2013-11-02T19:44:59 < Laurenceb__> hah that
2013-11-02T19:45:07 < Laurenceb__> haxored "multitasking"
2013-11-02T19:45:19 < PaulFertser> uip is really minimalistic in its design, it works in a way to be useable on some old megas and such. lwIP has more features and faster but requires more RAM/ROM.
2013-11-02T19:45:23 < Laurenceb__> multitasking via goto
2013-11-02T19:46:29 < efuentes> hmm
2013-11-02T19:47:23 < Steffan-> "lol stm32plus is fatfs with c++ wrappers" ...  proof of that Laurenceb__?
2013-11-02T19:47:39 < Laurenceb__> look in the github repo
2013-11-02T19:48:00 < Steffan-> yes .. https://github.com/andysworkshop/stm32plus/tree/master/lib/src/filesystem/fat ?
2013-11-02T19:49:05 < Laurenceb__> hmm maybe not
2013-11-02T19:49:14 < Laurenceb__> i found some example stuff but it was old
2013-11-02T19:49:29 < Laurenceb__> maybe an older version was using fatfs

2013-11-02T19:55:12 < efuentes> fbs if you really need to use floats and you want to print them
2013-11-02T19:55:24 < efuentes> you can do something like
2013-11-02T19:55:34 < efuentes> (uint32_t)(floatVal * 1000)
2013-11-02T19:55:36 < fbs> (int) (float * 100)
2013-11-02T19:55:38 < fbs> lol yea
2013-11-02T19:56:14 < efuentes> you cut out 40kb?
2013-11-02T19:56:34 < fbs> sprintf is almost 10k

2013-11-02T19:59:38 < efuentes> well you've got the space
2013-11-02T20:01:33 < Robint91> when is there a lowpower F4
2013-11-02T20:01:48 < jpa-> fbs: what are you using floats for?
2013-11-02T20:02:26 < fbs> pretty printing temperature sensor data
2013-11-02T20:02:47 < jpa-> can't see why you would need floats for that
2013-11-02T20:02:51 < jpa-> just use fixed point
2013-11-02T20:03:28 < fbs> stepsize is 0.0625, just doing ((float) temp)*0.065 is way easier for initial testing
2013-11-02T20:03:46 < fbs> now that most of it seems to work its time to clean up
2013-11-02T20:04:20 < jpa-> pretty much as simple:   int microcelcius = temp * 62500;
2013-11-02T20:05:32 < fbs> getting 19.25c printed would require more work tho
2013-11-02T20:05:40 < fbs> anyway thats what im doing now

2013-11-03T01:50:23 < Luggi09> allready tought about doing that, but I came to the conclusions such supercaps are far too expensive and store little energy
2013-11-03T01:50:52 < Luggi09> those 5ah usb chargers are available real cheap too
2013-11-03T01:54:10 < qyx_> some li-po's also have 10C charging rate, which would give full charge in about 6 minutes
2013-11-03T01:55:35 < zyp> I'd rather charge it slower and have it last longer
2013-11-03T01:56:28 < GargantuaSauce_> and have a smaller chance of burning your house down
2013-11-03T01:56:34 < Luggi09> 10C sounds very optimistic, proabably that's the typical chinese rating :)
2013-11-03T01:56:35 < qyx_> yep but it is good for cases when you have power available only for limited time
2013-11-03T01:56:54 < qyx_> eg. in the supercap use-case
2013-11-03T01:56:56 < Luggi09> afaik 5C is realistic on those a123 lifepo4 batteries
2013-11-03T01:59:15 < qyx_> or better.. use a phone which is able to work more than one day without charging :S
2013-11-03T02:02:43 < zyp> why do it have to be about phones? what about laptops?

2013-11-03T02:09:03 < zyp> though, I don't think being able to recharge my laptop faster would help much
2013-11-03T02:11:28 < BJfreeman> I believe a123 went bankrupt. best you can get from a  lifepo4 is 3c continous discharge
2013-11-03T02:13:19 < BJfreeman> depends on laptop. Have one that is good for 2hrs and a netbook that is good for 6hrs

2013-11-03T02:15:30 < zyp> that sounds pretty useless
2013-11-03T02:16:36 < BJfreeman> the 2hr one has a lot of bells and whistles that consume power
2013-11-03T02:16:59 < BJfreeman> net book is more conservitive.
2013-11-03T02:17:10 < zyp> and the 6hr one is too underpowered to do much useful

2013-11-03T02:20:42 < zyp> anyway, to put things in perspective; my laptop is a couple of years old, and has a sandy bridge i5, which means it's decently powerful for a laptop
2013-11-03T02:21:12 < zyp> and it has something like 5-8 hours of battery usage, depending on load
2013-11-03T02:21:41 < zyp> probably more if it's idle with brightness turned down so far that it's hard to read :p
2013-11-03T02:21:49 < BJfreeman> so you do Grapics computations or 3d transforms, other wise is it wasted
2013-11-03T02:22:25 < zyp> wasted how?
2013-11-03T02:23:08 < zyp> the HD3000 GPU in sandy brige is pretty weak
2013-11-03T02:23:28 < zyp> probably useless for fancy 3D games
2013-11-03T02:24:00 < BJfreeman> usually the Graphic display has it own gpu so does not use the main CPU
2013-11-03T02:24:27 < zyp> huh?
2013-11-03T02:24:53 < zyp> my laptop doesn't have any other GPU than the HD3000
2013-11-03T02:26:00 < BJfreeman> so what does your process manager say is the highest CPU usage
2013-11-03T02:26:21 < zyp> when?
2013-11-03T02:26:30 < BJfreeman> average
2013-11-03T02:26:39 < qyx_> firefox of course
2013-11-03T02:26:43 < zyp> dunno, why does that matter?
2013-11-03T02:27:22 < BJfreeman> ah well with that statement I bow out

2013-11-03T02:30:33 < zyp> obviously the cpu consuming task would depend on what the laptop is being used for, which could range from movie-watching to coding and compiling
2013-11-03T02:32:31 < BJfreeman> what I am saying is that most have more power than they use, it is all marketing hype
2013-11-03T02:33:39 < zyp> but that's not what we're discussing
2013-11-03T02:34:02 < BJfreeman> enven with graphics such as utube I only use 50% cpu anbd compiling less
2013-11-03T02:34:41 < zyp> well, compiling is a «best effort» task
2013-11-03T02:34:51 < qyx_> but this doesn't matter if we consider the overall efficiency
2013-11-03T02:34:53 < zyp> the more power you throw at it, the less time it takes

2013-11-03T02:35:14 < BJfreeman> not if your not using it
2013-11-03T02:35:15 < zyp> I also have an atom based netbook
2013-11-03T02:35:35 < qyx_> the most powerful cpu's are usually more efficient for a given task
2013-11-03T02:35:46 < qyx_> even if they are working only 1% of the time
2013-11-03T02:35:51 < zyp> I remember being amazed by how slow stuff compiles on it compared to other computers
2013-11-03T02:36:17 < BJfreeman> any way the bases was power usage on a battery, so more CPU speed translates to less battery time
2013-11-03T02:36:28 < zyp> no, it does not
2013-11-03T02:36:39 < qyx_> but we are in 2013 when cpu's have tons of power management features

2013-11-03T02:37:30 < BJfreeman> have any of you done any CPU design
2013-11-03T02:37:53 < zyp> top cpu speed/performance doesn't correlate with power consumption during idle
2013-11-03T02:38:45 < BJfreeman> zyp I agree but does not change my statement
2013-11-03T02:39:23 < GargantuaSauce_> my i5 ultrabook has about the same power consumption as my 1st-gen atom netbook
2013-11-03T02:39:44 < GargantuaSauce_> and outperforms it by a pretty ridiculous margin
2013-11-03T02:39:48 < zyp> it's completely uninteresting what the battery life would be if the cpu ran at 100% all the time
2013-11-03T02:39:59 < zyp> because that's not how real world usage is
2013-11-03T02:40:42 < zyp> a fast cpu can have just as good or better average power usage than a slow cpu, since they are mostly idle anyway
2013-11-03T02:41:12 < zyp> and since the fast cpu would make me wait less for stuff like compilation jobs, that's what I would prefer
2013-11-03T02:42:06 < BJfreeman> mixing apple and orages so my input is has no value
2013-11-03T02:43:01 < GargantuaSauce_> what are you even arguing
2013-11-03T02:44:00 < BJfreeman> from my view I am just giving knowledge
2013-11-03T02:44:03 < zyp> BJfreeman, I'm only talking about real world usage… of course if I ran my laptop at 100% cpu and you ran your netbook at 100% cpu, my laptop would run out of battery first :)
2013-11-03T02:45:57 < BJfreeman> zyp I am not sure how that fits into battery usage
2013-11-03T02:46:18 < zyp> me neither
2013-11-03T02:47:42 < BJfreeman> battery usage is what I was addressing
2013-11-03T02:48:34 < zyp> what I'm interested in is how long the battery will last when I'm stuck on a 10h flight in a seat without a power outlet and need to pass the time somehow
2013-11-03T02:49:35 < BJfreeman> I carry two extra batteries
2013-11-03T02:50:15 < BJfreeman> just in cas I am stuck on the tarmak for 3 hrs
2013-11-03T02:50:43 < zyp> I bought a 100 Wh external battery last year, for the flight home from japan
2013-11-03T02:51:39 < zyp> I believe I concluded it lasted for seven hours of movie watching, and then the internal battery in the laptop lasted for another five
2013-11-03T02:51:45 < dongs> i see BJfreeman is being an unreasonable blogger again

2013-11-03T02:59:36 < zyp> well, of course, if you're never without a power outlet, laptop battery life is not important

2013-11-03T14:23:05 < fbs> meh whats the problem?
2013-11-03T14:23:13 < fbs> did he ship what he promised?
2013-11-03T14:23:23 < dongs> the fact that its $20 of parts retailing for $200
2013-11-03T14:23:32 < dongs> targeted at audiophools / retards
2013-11-03T14:23:45 < fbs> meh youre just bitching
2013-11-03T14:23:57 < fbs> if people are willing to pay why not?
2013-11-03T14:28:25 < fbs> do you also send hate mails to agilent crying that uni-t sells for $15?
2013-11-03T14:42:36 < mervaka> dongs: found an extensive forum debate about it, the designer a participant. they're apparently using an ESS DAC
2013-11-03T14:42:51 < mervaka> and.. they are going for a fucking mini XLR connector?!

2013-11-03T14:43:37 < dongs> that makes it do 384k sampling rate

2013-11-03T14:44:02 < mervaka> CD audio is 44.1 16 bit. you can't get around that.
2013-11-03T14:44:07 < dongs> right.
2013-11-03T14:44:38 < mervaka> best case, you have zero jitter and 96dB dynamic range
2013-11-03T14:44:40 < dongs> im sure hte type of dudes this is targeted to rip CDs to .wav, then reencode to flac and play back at 384khz/24bit

2013-11-03T15:34:28 < PaulFertser> Laurenceb__: n900 has a nice hardware kb, there's plenty of spare parts available cheap from ebay
2013-11-03T15:34:34 < Laurenceb__> yeah
2013-11-03T15:34:48 < Laurenceb__> but that seems ambitious for 25000 euros
2013-11-03T15:34:52 < dongs> 3.5" TFT, 800x480, resistive
2013-11-03T15:35:33 < PaulFertser> dongs: this is meant as an upgrade to n900 users who just can't switch to modern devices because they like maemo and apps for maemo, and can't like android.
2013-11-03T15:35:47 < dongs> maemo? isnt that some dead lunix
2013-11-03T15:35:51 < dongs> there are apps for it?
2013-11-03T15:36:08 < PaulFertser> dongs: yes, and an established community around it, still alive.
2013-11-03T15:36:42 < dongs> probably as alive as N900
2013-11-03T15:36:56 < PaulFertser> Laurenceb__: the key here is that all the mechanical parts are already available thanks to n900 popularity, and all the core functionality of the replacement MB is already tested in gta04 project.

2013-11-03T15:48:12 < dongs> lol really
2013-11-03T15:48:16 < dongs> and waht are they connecting the modem with
2013-11-03T15:48:19 < dongs> UART??
2013-11-03T15:48:25 < dongs> i doubt lunix supports mipi-hsi
2013-11-03T15:49:48 < zyp> of course it does
2013-11-03T15:49:58 < dongs> how would you know, troll
2013-11-03T15:50:07 < dongs> <zyp> cuz i wrote drivers for it lolol
2013-11-03T15:50:23 < zyp> because android is based on linux, and plenty of android devices are using hsi
2013-11-03T15:50:59 < Laurenceb__> seems the processor they plan to use supports it
2013-11-03T15:51:15 < dongs> well wahtever
2013-11-03T15:51:24 < dongs> im sure they'll go ahead and hook it up with UART anyway.

2013-11-03T16:09:13 < zyp> PaulFertser, it does
2013-11-03T16:09:21 < dongs> barely
2013-11-03T16:09:45 < zyp> most modern phones seem to be using HSIC, which is HS USB with a cheaper PHY layer

2013-11-03T16:15:13 < zyp> umm, LTE?
2013-11-03T16:15:37 < zyp> they mention the GTM601 module, which is apparently based on qualcomm MDM6200
2013-11-03T16:15:49 < zyp> which «Only supports HSPA+ with data rates of up to 14.4 Mbit/s»
2013-11-03T16:16:42 < dongs> Multiple options planned!

2013-11-03T16:16:42 < dongs> LTE 100/50 Mbps
2013-11-03T16:17:16 < zyp> ok, I just looked at the schematic which states GTM601
2013-11-03T16:17:28 < PaulFertser> dongs: n900 folks are not your typical unsuspecting "dickstarter regulars", they know what this upgrade actually means and what it doesn't.

2013-11-03T16:18:02 < PaulFertser> zyp: they're going to use a bit more advanced Option module for neo900 than the one used on gta04.

2013-11-03T16:18:43 < zyp> as far as I can see, n900 was based on omap3, how is stuffing a new omap3 into it an upgrade?

2013-11-04T01:26:21 < zyp> why?
2013-11-04T01:33:50 < Tectu> zyp, have you read read the RM of the STM32F42x ?
2013-11-04T01:34:18 < Tectu> they have the new FMC interface to interface SDRAM and such
2013-11-04T01:34:22 < Tectu> but they still have the old FSMC
2013-11-04T01:34:32 < Tectu> and the FMC chapter says taht you can also interface SRAM with it
2013-11-04T01:34:34 < Tectu> and PC Cards
2013-11-04T01:34:40 < Tectu> so why should I want to use the FSMC at all?
2013-11-04T01:34:55 < Tectu> --> to me it look slike the FMC can handle everything the FSMC can do as well

2013-11-04T01:46:17 < zyp> there is no FSMC in f429
2013-11-04T01:46:42 < zyp> the RM covers all F4s, they either have FSMC or FMC, not both
2013-11-04T01:47:28 < Tectu> aah
2013-11-04T01:47:30 < Tectu> where did I miss that?
2013-11-04T01:47:33 < zyp> see the «This section applies to …» in each of the chapters
2013-11-04T01:47:45 < Tectu> meh... thanks!
2013-11-04T01:47:53 < Tectu> This section applies to the whole STM32F40x/41x family only.
2013-11-04T01:48:40 < zyp> anyway, I think the FSMC and FMC is pretty much the same thing, FMC is probably just a superset of FSMC with more register to account for the additional features

2013-11-04T03:00:46 < efuentes> i guess it doesn't matter
2013-11-04T03:01:01 < efuentes> the boot load seems fine
2013-11-04T03:01:13 < efuentes> as long as you're linking your application at to the right address
2013-11-04T03:01:28 < gxti> well it sort of works, which rules out loading the wrong address
2013-11-04T03:01:41 < gxti> it just hangs immediately due to an issue with an OS stack

2013-11-04T03:11:06 < dongs> you have that properly set at 80003000 or wahtever?

2013-11-04T03:26:45 < dongs> for trash assembly places y ou generally have to provide
2013-11-04T03:26:52 < dongs> proper places will have all the common stuff on hand and loaded
2013-11-04T03:27:06 < efuentes> right
2013-11-04T03:27:18 < efuentes> I just had our assembler source the components
2013-11-04T03:27:22 < dongs> thats how one of my projects got assembled in taiwan
2013-11-04T03:27:25 < efuentes> and I picked up completed units
2013-11-04T03:27:29 < dongs> i only had to provide ~5-6 uncommon parts
2013-11-04T03:27:38 < dongs> like stm32 and some oddball diode and shit i was using
2013-11-04T03:27:48 < dongs> everything else, all passives/leds/etc they had on hand

2013-11-04T03:30:06 < dongs> they had boards since almost a month ago

2013-11-04T03:31:07 < dongs> they showed pcb panels on 18th

2013-11-04T04:14:04 < efuentes> does your application work without the bootloader?
2013-11-04T04:14:51 < gxti> yes.
2013-11-04T04:14:55 < dongs> do you reset vtor in your applicataion
2013-11-04T04:15:01 < dongs> i.e. if youre using stdperiphlib startup shit
2013-11-04T04:15:02 < gxti> yes.
2013-11-04T04:15:05 < dongs> it'll reset vtor
2013-11-04T04:15:09 < gxti> no stdperiph
2013-11-04T04:15:12 < dongs> SystemInit shit.

2013-11-04T04:16:02 < dongs> lol.
2013-11-04T04:16:10 < gxti> without bootloader (when it works) i'm still using the same VTOR, just with a dummy vtor at 0 that jumps to the offset one
2013-11-04T04:16:32 < gxti> so vtor is the same either way...

2013-11-04T07:41:41 < emeb_mac> for a function generator?
2013-11-04T07:41:45 < dongs> yes?
2013-11-04T07:41:54 < emeb_mac> with the on-chip DACs?
2013-11-04T07:42:14 < dongs> 16bit wide gpio and r2r
2013-11-04T07:42:22 < emeb_mac> yech!
2013-11-04T07:42:39 < dongs> pfft
2013-11-04T07:42:45 < dongs> it'll be better than 2 decades old shit from ebay
2013-11-04T07:43:31 < emeb_mac> ancient HP fngen would kick your ass for signal quality, drive, spurs, etc.
2013-11-04T07:43:53 < emeb_mac> 16-bit r2r driven directly from GPIO would be some nasty-ass shit
2013-11-04T07:44:09 < emeb_mac> supply & clock feedthru. total trash.
2013-11-04T07:45:16 < emeb_mac> but I don't want to seem negative. :)
2013-11-04T07:45:59 < dongs> http://www.scienceprog.com/avr-dds-signal-generator-v20/ shit even avr can do 8mhz and looks perfectly fine, look at scope screenshots
2013-11-04T07:46:05 < dongs> are you telling me STM32 cant?
2013-11-04T07:46:25 < dongs> http://www.scienceprog.com/wp-content/uploads/2008i/DDS2/.thumbs/.AVR_DDS_triangle.JPG http://www.scienceprog.com/wp-content/uploads/2008i/DDS2/.thumbs/.AVR_DDS_sine.JPG
2013-11-04T07:47:02 < emeb_mac> did you look at the glitches in that sine?
2013-11-04T07:47:12 < dongs> yes, those are probably cuz avr sucks :)O
2013-11-04T07:47:36 < emeb_mac> I shudder to think what that would look like on a spectrum anayzer - spurs are probably down like 10dB.
2013-11-04T07:48:22 < emeb_mac> You could do hobby-grade fngen w/ STM32F4
2013-11-04T07:48:49 < dongs> emeb_mac: that guy etches his single-sided pcbs at home
2013-11-04T07:48:58 < emeb_mac> lol
2013-11-04T07:48:59 < dongs> i'm pretty sure a "hobby-grade" shit will be more tha nenough for him.
2013-11-04T07:49:33 < emeb_mac> upgrdman asked for 30MHz - dunno how well an F4 could run GPIO to do that.
2013-11-04T07:49:47 < dongs> you can DMA at GPIO speed right?
2013-11-04T07:50:03 < emeb_mac> maybe. never tried.
2013-11-04T07:50:30 < dongs> i wonder how many cycles it take sto toggle gpio w/dma
2013-11-04T07:50:41 < GargantuaSauce_> even without dma it's stupid fast
2013-11-04T07:50:55 < dongs> not nearly as fast as AVR
2013-11-04T07:51:08 < emeb_mac> haha
2013-11-04T07:52:34 < emeb_mac> the latest project: https://dl.dropboxusercontent.com/u/17017364/2013-11-03%2021.19.31.jpg
2013-11-04T07:52:50 < emeb_mac> beaglebone talking to a Spartan6
2013-11-04T07:53:22 < dongs> nice resistor network in top left
2013-11-04T07:53:26 < dongs> is half of it unused?
2013-11-04T07:53:39 < emeb_mac> 5 used, 3 unused.
2013-11-04T07:53:42 < emeb_mac> for the LEDs
2013-11-04T07:53:45 < dongs> heh
2013-11-04T07:53:58 < emeb_mac> stenciled that one
2013-11-04T07:54:12 < emeb_mac> that kapton stencil worked OK.
2013-11-04T07:54:28 < emeb_mac> only used it for the UDFN10 and that resistor array tho
2013-11-04T07:55:09 < emeb_mac> would have been cheaper to go with separate resistors instead of that array.
2013-11-04T07:55:35 < emeb_mac> but the guy who's going to build these says it costs him $0.10/part for picknplace.
2013-11-04T07:55:45 < emeb_mac> so that means the array is cheaper to build.

2013-11-04T09:17:12 < emeb_mac> yep
2013-11-04T09:17:22 < emeb_mac> just found the schematic
2013-11-04T09:17:31 < emeb_mac> man - who drew that POS
2013-11-04T09:18:41 < emeb_mac> reasonably priced - only ~$8 single from DK
2013-11-04T09:24:52 < dongs> im sure it was made in eagle
2013-11-04T09:26:17 < emeb_mac> really?
2013-11-04T09:26:37 < emeb_mac> those yellow filled IC symbols look more like altium.
2013-11-04T09:30:50 < jpa-> yeah, it looks a lot like altium
2013-11-04T09:31:20 < jpa-> and IMO it's not that bad.. but i'm not sure if that tells more about my schematics skills than it tells about the schematic ;)

2013-11-04T12:29:41 < zyp> I kinda forgot about them too, until people came asking me for status now

2013-11-04T12:31:48 < dongs> yeah but pics looked usable, tho they were too "high"
2013-11-04T12:31:57 < dongs> which means probably from bottom entry it wouldnt reach all the way to full contact

2013-11-04T15:55:33 < Laurenceb> yup lolz
2013-11-04T15:55:46 < dongie> i think he needs proof of "fraud"
2013-11-04T15:56:14 < Laurenceb> that the photos are showing cheap lenses with white LED behind them
2013-11-04T15:56:17 < Laurenceb> not a projector
2013-11-04T15:56:37 < dongie> yeah i dont really see how they're fitting any kinda "projector" in that space
2013-11-04T15:56:45 < Laurenceb> cuz projectors that small dont exist
2013-11-04T15:56:49 < Laurenceb> apart from from ST
2013-11-04T15:56:54 < Laurenceb> their mems laser thing
2013-11-04T15:56:56 < dongie> but tehy gonna develop it with 600k right???
2013-11-04T15:57:01 < dongie> jeri wil lsave all

2013-11-04T15:57:16 < dongie> oh, hypeberry has hdmi
2013-11-04T15:57:19 < dongie> did they have any issues with it?
2013-11-04T15:57:23 < Laurenceb> a sane person would get ST involved
2013-11-04T15:57:27 < dongie> ill steal thier reference schematic
2013-11-04T15:57:30 < Laurenceb> they have all the driver ICs and stuff
2013-11-04T15:58:10 < Laurenceb> aiui there are issues with hdmi backpowering the device or something on rpi
2013-11-04T15:58:15 < dongie> haha
2013-11-04T15:58:32 < dongie> what the hell...
2013-11-04T15:58:38 < dongie> they're routing hpd through some weird shit
2013-11-04T15:58:44 < dongie> lol nice ESD protection
2013-11-04T15:58:46 < Laurenceb> at least on first version before sony guys fixed it for them
2013-11-04T15:59:00 < dongie> LETS USE 3 BAV99'S
2013-11-04T15:59:05 < dongie> instead of SOT23-6 TVS
2013-11-04T15:59:10 < dongie> makes total sense

2013-11-04T16:00:08 < dongie> oo
2013-11-04T16:00:13 < dongie> i guess shitberry hdmi is not 5V tolerant
2013-11-04T16:00:17 < dongie> so tehy have to run it through soem ghetto buffer
2013-11-04T16:00:30 < dongie> hm no.. I2C/SCL is
2013-11-04T16:00:47 < dongie> but not HPD. such fail
2013-11-04T16:00:55 < dongie> BCM sucks
2013-11-04T16:01:26 < dongie> they do haev a diode
2013-11-04T16:01:29 < dongie> on 5V_HDMI
2013-11-04T16:01:42 < dongie> but they're a source, not listener
2013-11-04T16:01:46 < dongie> listener takes 5V
2013-11-04T16:01:51 < dongie> source should provide it
2013-11-04T16:01:59 < dongie> looks OK on that schema, i duno what rev0 looked like

2013-11-04T16:35:01 < gxti> at least it's failing differently
2013-11-04T16:37:37 < gxti> no crash, it's just not running any threads
2013-11-04T16:37:52 < gxti> must have broken some irq handler
2013-11-04T16:41:39 < gxti> nevermind, i know why. it's still inside my soft irq handler, so the pendsv crap never gets priority. rofl.
2013-11-04T16:41:59 < gxti> ok so how the hell do i switch to MSP
2013-11-04T16:44:20 < zyp> why do you switch to PSP in the first place?
2013-11-04T16:45:33 < gxti> what do you mean? i'm initiating the jump from a thread, hence psp
2013-11-04T16:45:36 < zyp> the trick is to put the bootloader/normal mode check as early as possible, before you do lots of initialization that you have to undo before jumping to application
2013-11-04T16:46:19 < zyp> if you want to use threads and shit in the bootloader, do that stuff after you've decided that you don't want to jump to application
2013-11-04T16:46:42 < gxti> that's true. however, right now my 'ok check' involves comparing the current firmware so i'd need to wire up something so it can compare, set a flag, and reset. which might be best anyway.
2013-11-04T16:47:42 < zyp> yeah
2013-11-04T16:47:46 < gxti> but just for the sake of knowledge and stuff, how the hell do i switch to MSP? mangle LR?
2013-11-04T16:48:35 < zyp> hmm
2013-11-04T16:49:17 < gxti> i think i could 1) disable all irq, enable some arbitrary soft irq like tamper 2) fire tamper 3) tamper mangles lr so it returns to msp 4) return and original func is now msp, do jump
2013-11-04T16:49:21 < gxti> seems kind of icky
2013-11-04T16:49:41 < gxti> but it would probably be the same thing that rtos that use msp for at least one thread (like chibios, i'm guessing) are doing
2013-11-04T16:50:00 < zyp> I believe you could also modify the register containing the msp/psp flag
2013-11-04T16:50:08 < zyp> but I don't remember which
2013-11-04T16:50:27 < zyp> I believe that's how you usually switch from msp to psp in the first place
2013-11-04T16:50:33 < gxti> i was looking at the manual this morning, it only occurred to me as i was trying to fall asleep that i was having problems because i was using the wrong stack
2013-11-04T16:50:49 < gxti> i remember seeing something about how only irqs can switch to msp but i might have misread

2013-11-04T16:51:28 < zyp> there is some privileged/unprivileged stuff as well
2013-11-04T16:51:54 < zyp> the idea is that unprivileged threads shouldn't be able to touch msp, and thereby not be able to mess up the entire system
2013-11-04T16:51:56 < gxti> yeah none of that in my case
2013-11-04T16:52:13 < zyp> but I'm not sure that also applies to privileged threads
2013-11-04T16:52:53 < gxti> i do think branching before rtos happens is smarter though, maybe i'll use the BMP trick where it sets an unused gpio then does a core-only reset
2013-11-04T16:53:21 < zyp> just use a memory location, memory isn't cleared on reset
2013-11-04T16:54:08 < zyp> in my bootloader I'm using the first word of ccm (f303) for this
2013-11-04T16:54:56 < gxti> is memory never cleared, or only core reset doesn't?
2013-11-04T16:55:13 < zyp> memory is never cleared
2013-11-04T16:55:27 < zyp> that's why uninitialized memory contains garbage
2013-11-04T16:55:38 < zyp> .bss is cleared by the startup code though
2013-11-04T16:56:20 < gxti> i never looked very closely at what uninitialized memory does, because i guess i never have any
2013-11-04T16:57:05 < zyp> stack/heap is usually uninitialized
2013-11-04T16:57:41 < zyp> so it's not guaranteed to contain zero the first time you use a location after powerup
2013-11-04T16:58:09 < gxti> mine's always in bss, if for no other reason than that i'm declaring them as ordinary static vars
2013-11-04T17:00:41 < zyp> http://cgit.jvnv.net/arcin/tree/bootloader.cpp#n274 <- in my bootloader I turn on GPIO before deciding, but I wait until after deciding before I turn on HSE, PLL and systick

2013-11-04T17:43:29 < gxti> can't really debug why the hex file fails though because it's out of sync with the stuff in my tree and i'm at work so i can't write a new hex file. oh well, good enough for now. should do some actual work now.

2013-11-04T17:52:15 < zyp> yep
2013-11-04T17:52:22 < dongie> that looks too expensive

2013-11-04T17:52:50 < zyp> dunno
2013-11-04T17:52:54 < dongie> im gonna put 4 lanes of DSI on a separate daughterboard w/power + FPC/whatever specific to panel

2013-11-04T17:58:06 < qyx_> hm, where should be the 22R resistors placed on usb d+ and d-?
2013-11-04T17:58:15 < qyx_> near the stm or near the connector?
2013-11-04T17:58:15 < dongie> 'wehre'?
2013-11-04T17:58:17 < dongie> oh
2013-11-04T17:58:27 < gxti> near stm, if possible
2013-11-04T17:58:35 < qyx_> i suppose they are used as a trermination
2013-11-04T17:58:36 < qyx_> ah, ok
2013-11-04T17:58:45 < gxti> the connector is passive so there's no reason you would need to place it near there
2013-11-04T17:59:00 < karlp> more importantly, does it matter at all?
2013-11-04T17:59:12 < gxti> probably only a tiny bit, if at all
2013-11-04T17:59:21 < karlp> probably at all for LS/FS?
2013-11-04T17:59:23 < dongie> nxt question, where should 1.5K pullup be :)
2013-11-04T17:59:26 < dongie> before or after 22R
2013-11-04T18:00:03 < gxti> after but 1500 ohms vs 1522... not much difference
2013-11-04T18:00:11 < zyp> what is after?
2013-11-04T18:00:32 < zyp> is stm first or last? :p
2013-11-04T18:00:36 < qyx_> i can't see it on F4 discovery schematic, is it internal?
2013-11-04T18:00:37 < gxti> connector side
2013-11-04T18:00:52 < dongie> F3 doesnt need 22R
2013-11-04T18:00:57 < dongie> i think OTG has built in 1.5K
2013-11-04T18:00:59 < dongie> OTG side
2013-11-04T18:00:59 < gxti> but again, it's only 22 extra ohms so you could do either if it helped layout

2013-11-05T00:28:13 < gxti> sure, seems like something that would be handy to have anyway
2013-11-05T00:34:11 < Laurenceb__> you can use "Brasso" or other metal cleaners to polish up the plastic

2013-11-05T00:48:46 < gxti> not really pleased with the overall rigidity of 2mm acrylic, if i did it again i would use 3mm at minimum but really metal is what i want
2013-11-05T00:49:30 < gxti> after i fix the microsd slot i'll send a quote to hammond and see if their customization prices are reasonable
2013-11-05T00:50:01 < Laurenceb__> not very aiui
2013-11-05T00:50:11 < Laurenceb__> luckily i have access to a CNC mill
2013-11-05T00:50:18 < gxti> i heard something good about it once but i'm assuming the worst
2013-11-05T00:50:21 < Laurenceb__> to make custom milled hammon enclosures
2013-11-05T00:50:30 < Laurenceb__> its in the $k range
2013-11-05T00:50:37 < gxti> oic.
2013-11-05T00:50:49 < Laurenceb__> depending on what you want
2013-11-05T00:50:56 < Laurenceb__> that quote was for milled stuff
2013-11-05T00:50:56 < ds2> 0.096 stuff is pretty flimsy
2013-11-05T00:51:03 < Laurenceb__> custom molds is going to be more
2013-11-05T00:51:19 < gxti> it's just flat alum end plates
2013-11-05T00:51:25 < gxti> for an extruded alum enclosure
2013-11-05T00:52:34 < Laurenceb__> ah so milling would work
2013-11-05T00:52:37 < gxti> basic stuff: http://partiallystapled.com/~gxti/circuits/2013/10/13-rev6_solid.png other than the countersink which i can live without. but the hammond stock plates are already countersunk. so in theory it's possible, but unlikely, that the price is ok.
2013-11-05T00:52:39 < Laurenceb__> might not be too expensive
2013-11-05T00:52:56 < gxti> don't even really care about engraving/sink
2013-11-05T00:53:00 < gxti> silk*
2013-11-05T00:53:11 < Laurenceb__> you can DIY it easily
2013-11-05T00:53:34 < Laurenceb__> if hammond are too expensive, local machine shop should do it
2013-11-05T00:53:36 < gxti> i have zero machine tools or access thereto :p

2013-11-05T00:57:24 < Laurenceb__> theres go to be somewhere near you?
2013-11-05T00:58:31 < gxti> no hackerspace type craps around afaik, used to be techshop which was expensive but apparently not enough profit and they closed
2013-11-05T00:58:45 < Laurenceb__> ur doing it wrong
2013-11-05T00:58:49 < Laurenceb__> go somewhere pro
2013-11-05T00:58:54 < gxti> yeah, i just have no idea where they are.
2013-11-05T00:59:14 < Laurenceb__> http://www.jcb.com/  <- pro, not a hackspace
2013-11-05T00:59:33 < Laurenceb__> tho of course they wont do stuff to order usually
2013-11-05T00:59:47 < Laurenceb__> i just know the right people, but if you make friends with someone...
2013-11-05T01:01:01 < Laurenceb__> where do you live?
2013-11-05T01:02:24 < gxti> i do actually have a lead on someone who might be able to help, he cloned the enclosure i'm using and was going to send a sample but i think he got busy and forgot

2013-11-05T01:05:47 < Laurenceb__> hah
2013-11-05T01:05:54 < Laurenceb__> a bit heavy
2013-11-05T01:06:04 < Laurenceb__> maybe for an RF sniffer flight
2013-11-05T01:06:10 < Laurenceb__> something ive been wanting to try
2013-11-05T01:06:13 < gxti> gotta have somewhere to put that 4k 120fps
2013-11-05T01:06:35 < Laurenceb__> i was thinking ultrawideband raw RF
2013-11-05T01:06:48 < Laurenceb__> then see what you can find in the data later
2013-11-05T01:06:59 < Laurenceb__> hmmmm
2013-11-05T01:07:00 < gxti> oh, and 3d of course
2013-11-05T01:07:03 < Robint91> what UWB?
2013-11-05T01:07:05 < gxti> not that you can tell
2013-11-05T01:07:11 < Laurenceb__> or use that GSM crack
2013-11-05T01:07:35 < Laurenceb__> for massive scale airborne phone hacking
2013-11-05T01:08:01 < Steffan-> Why it has to be airborn.. you can also just drive around in your car :)
2013-11-05T01:08:05 < Laurenceb__> "NSA-HAB"
2013-11-05T01:08:07 < Laurenceb__> yes
2013-11-05T01:08:26 < Laurenceb__> but from the air with a phased array you could listen to many base stations
2013-11-05T01:08:28 < Steffan-> ( if you have your drivers license )
2013-11-05T01:08:41 < Laurenceb__> hard to track someone
2013-11-05T01:08:54 < Laurenceb__> in a car
2013-11-05T01:09:30 < Laurenceb__> as you can't easily break it in real time
2013-11-05T01:09:33 < Laurenceb__> hence the HDD
2013-11-05T01:11:07  * Laurenceb__ maniacal laughter
2013-11-05T01:11:40 < Steffan-> i wonder when MI6 comes to say hi to you.
2013-11-05T01:12:33 < Steffan-> Or whatever weird agencies you have over there
2013-11-05T01:12:41 < Laurenceb__> heh
2013-11-05T01:12:56 < Laurenceb__> actually it might suffer from bottleneck
2013-11-05T01:13:14 < Laurenceb__> there would be lots of data going into the HDD from a phased array
2013-11-05T01:13:16 < Steffan-> you're rpi won't be fast enough?

2013-11-05T01:13:56 < Laurenceb__> would have to be FPGA
2013-11-05T01:13:59 < Laurenceb__> ds2 yes
2013-11-05T01:14:19 < Laurenceb__> they have a huge machine shop full of 5 axis mills
2013-11-05T01:14:21  * Robint91 has a problem because a  3GSPS ADC
2013-11-05T01:14:32 < Laurenceb__> like hundreds of them XD
2013-11-05T01:14:33 < Robint91> like 8Bits
2013-11-05T01:14:50 < Robint91> Interfacing that thing to a fpga is HORROR
2013-11-05T01:14:51 < ds2> "huge" is that like saying boeing's factorys are a wee bit large?
2013-11-05T01:14:59 < Laurenceb__> heh
2013-11-05T01:15:13 < Robint91> * two of those
2013-11-05T01:15:18 < Laurenceb__> but yeah i know someone who will let me have time on a 5 axis mill XD
2013-11-05T01:15:21 < Robint91> one for the I and Q path
2013-11-05T01:15:51 < Steffan-> It's always nice to have the right contacts Laurenceb__ :)
2013-11-05T01:16:18 < Laurenceb__> Robint91: the clk is 3GHz?!

2013-11-05T01:16:33 < Laurenceb__> uh oh
2013-11-05T01:16:46 < Robint91> Laurenceb__, two ADCs each doing 3GSPS
2013-11-05T01:16:56 < Laurenceb__> ds2: too much time to fit in at end of shift :P
2013-11-05T01:17:00 < Robint91> we can push to 6GSPS but it gets tricky

2013-11-05T01:27:24 < qyx_> uhm, so if you wanted to record single receiving antenna on common ssd's you would need at least 10-15 of them

2013-11-05T01:42:00 < kuldeepdhaka> fall in using gdb and st-util
2013-11-05T01:50:05 < Steffan-> Why you use the stm32f4-discovery(?) when it comes with "a built-in debug interface for flash programming and run-control"?

2013-11-05T08:25:15 < gxti> had a silly issue, objcopy does not bother aligning its ihex output and i had a bug handling that
2013-11-05T08:28:30 < emeb_mac> oops
2013-11-05T08:30:39 < emeb_mac> what's special about this bootloader (that you can't get from others)?
2013-11-05T08:31:50 < gxti> loads from SD (not special), permissively licensed, uses a two-part linker scheme where the code lives at the end of flash and only takes the first flash block
2013-11-05T08:32:11 < emeb_mac> cool
2013-11-05T08:32:31 < emeb_mac> what processor does it target?
2013-11-05T08:33:09 < gxti> f1 but things are vaguely modular, not as much as chibios though. mostly fixing the dma would be the sucky part.
2013-11-05T08:33:31 < emeb_mac> what uses dma? SD SPI?
2013-11-05T08:34:08 < gxti> yeah
2013-11-05T08:34:46 < emeb_mac> does the SD use a FAT filesys, or just raw blocks?
2013-11-05T08:35:11 < gxti> fat, and the firmware is ihex. although i might look at an elf loader at some point.
2013-11-05T08:35:48 < emeb_mac> why not just raw binary w/ fixed load addr?
2013-11-05T08:35:58 < gxti> idiot-proof
2013-11-05T08:36:17 < emeb_mac> whenever you idiot-proof something, the world invents better idiots...
2013-11-05T08:36:31 < gxti> better to use file formats where mangling the newlines doesn't hurt
2013-11-05T08:36:44 < emeb_mac> heh.
2013-11-05T08:36:48 < gxti> it really mattered when i was doing a tftp network loader, because it defaults to 'text' mode (i.e. mangle your newlines)
2013-11-05T08:36:56 < emeb_mac> how big is the bootloader?
2013-11-05T08:38:10 < gxti> just under 16k, not the tiniest
2013-11-05T08:38:47 < emeb_mac> not bad considering what it does tho.
2013-11-05T08:39:22 < emeb_mac> does it look for a fixed file name on SD at boot time?
2013-11-05T08:39:46 < gxti> yep, and always tries to load it (compares each block before erasing of course)
2013-11-05T08:40:38 < emeb_mac> that would be a nice thing about using non-binary - having error checking in the file format.
2013-11-05T08:41:45 < emeb_mac> anyway, I've got so many questions because I was thinking about something along this line a while back.
2013-11-05T08:42:10 < emeb_mac> I think I've convinced myself just to use the USB DFU bootloader that's built-in tho.

2013-11-05T18:00:27 < karlp> zeropointo: regexs are not the solution: http://stackoverflow.com/a/1732454/600217
2013-11-05T18:00:42 < karlp> what are you doing that you feel regexs _are_ a solution that you're running on a stm32?
2013-11-05T18:02:40 < emeb> Obligatory: 'Some people, when confronted with a problem, think "I know, I'll use regular expressions." Now they have two problems.'
2013-11-05T18:04:58 < zeropointo> regex are great for validating input.
2013-11-05T18:05:20 < BrainDamage> regex are state machines in unreadble format
2013-11-05T18:06:28 < emeb> just write the damned state machine.

2013-11-06T02:45:46 < dongs> just thinking something that small isnt going to hold together very well

2013-11-06T23:40:41 < Laurenceb__> ok im confused now
2013-11-06T23:40:43 < Laurenceb__> __Stack_Init = _estack  - __Stack_Size ;
2013-11-06T23:41:00 < Laurenceb__> in RAISONANCE code
2013-11-06T23:41:09 < Laurenceb__> how does that make any sense?

2013-11-06T23:57:03 < gxti> the name doesn't make any sense but the math does. stacks grow down.
2013-11-06T23:57:36 < gxti> _estack is what goes in the vector
2013-11-06T23:58:11 < gxti> which is a common name for it. __Stack_Init not so much, especially since it's not the value that you initialize the stack to...
2013-11-06T23:58:32 < gxti> i vastly prefer declaring the stack as a regular C variable
2013-11-06T23:59:33 < gxti> with the minimum possible linker script, vector table init and stack in C, no assembler at all aside from whatever inline crap is absolutely necessary

2013-11-07T00:09:47 < Laurenceb__> http://www.eventhelix.com/realtimemantra/basics/images/stack_heap.gif
2013-11-07T00:09:54 < Laurenceb__> "stacks grow up"
2013-11-07T00:10:06 < fbs> not in cortex
2013-11-07T00:10:22 < fbs> you set the stack to end of ram and it grows down
2013-11-07T00:10:26 < zyp> heap grows upwards, stack grows downwards
2013-11-07T00:10:37 < Laurenceb__> oh lol
2013-11-07T00:11:24 < fbs> The processor uses a full descending stack. This means the stack pointer holds the address of the last stacked item in memory. When the processor pushes a new item onto the stack, it decrements the stack pointer and then writes the item to the new memory location
2013-11-07T00:12:28 < Laurenceb__> i see
2013-11-07T00:12:52 < Laurenceb__> so how do i use the RAM LENGTH in the linker to set the location?
2013-11-07T00:13:07 < fbs> _estack = ORIGIN(RAM)+LENGTH(RAM); is what i got
2013-11-07T00:13:13 < fbs> for a f0
2013-11-07T00:13:20 < karlp> gxti: what asm have you needed at all for startup?
2013-11-07T00:13:25 < Laurenceb__> aha
2013-11-07T00:13:27 < Laurenceb__> simple
2013-11-07T00:14:00 < fbs>   ldr r0, =_estack
2013-11-07T00:14:02 < fbs>   mov sp, r0
2013-11-07T00:14:05 < fbs> is the asm im using for it
2013-11-07T00:21:48 < zyp> that's pretty pointless
2013-11-07T00:21:48 < zyp> hardware is grabbing the initial sp value from vector 0 when entering the reset handler
2013-11-07T00:21:48 < fbs> its actually the startupfile supplied by st :p
2013-11-07T00:21:48 < zyp> so provided you are setting up your vectors correctly, what you are doing is completely pointless :p
2013-11-07T00:21:48 < Laurenceb__> thats what im using
2013-11-07T00:21:48 < Laurenceb__> cleaning up some linker scripts and ive broken it :P
2013-11-07T00:21:48 < zyp> maybe you should clean up your startup code as well
2013-11-07T00:21:48 < fbs> maybe one day, thansk for the tip anyway

2013-11-07T00:40:05 < gxti> i guess none of the asm in my crt0.c is necessary. it's just loading msp, and disabling interrupts, both of which i wrote under the assumption that the bootloader would make those necessary. but now that i actually wrote the bootloader i see they are not.
2013-11-07T00:42:01 < gxti> i don't quite get why msp is in the vector table anyway, seems simpler to just always make startup code do it

2013-11-07T12:49:43 < Laurenceb__> what symbols does GAE malloc require to work?
2013-11-07T12:49:53 < Laurenceb__> needs some kind of heap initialisation??

2013-11-07T14:04:21 < zyp> when you are placing two i2c devices on a bus, there are two other devices on the bus, and the devices lets you pick from nine different addrs, how the fuck do you manage to pick one of the addrs that are already in use?

2013-11-07T17:08:42 < fbs> gxti: yes, stuck
2013-11-07T17:08:48 < dongs> its just i have all the stuff already in dicktrace and it would take time to migrate it all.
2013-11-07T17:08:50 < fbs> not going to redo list and crap
2013-11-07T17:09:01 < fbs> and unlearn all the shortcuts
2013-11-07T17:09:11 < dongs> thats another thing dicktrace lacks in
2013-11-07T17:09:27 < dongs> shortcut stuff is really limited, AND they actually removeod a wholebunch of menu hotkeys in recent release
2013-11-07T17:09:37 < fbs> finally feel like im somewhat efficient with it
2013-11-07T17:09:40 < dongs> i bitched about it on bugtracker for a while, they didn't even realize they "removed" it as they had no idea people sued that shit
2013-11-07T17:09:55 < dongs> stuff like alt-a-b-c
2013-11-07T17:10:01 < dongs> to select menu options
2013-11-07T17:10:11 < dongs> or rightclick+letter for menu.

2013-11-07T17:10:27 < fbs>  p t
2013-11-07T17:10:29 < dongs> and then its all hotkey'd from tehre so you can quickly press a couple letters to get shit done
2013-11-07T17:10:33 < gxti> mostly right. there's still some obnoxious shit.
2013-11-07T17:10:46 < fbs> there are some wristbreakers
2013-11-07T17:10:49 < dongs> im sure not nearly as obnoxious as some limittaions of dicktrace.
2013-11-07T17:11:43 < dongs> my biggest beef with altium is layers
2013-11-07T17:11:53 < dongs> you cannot quickly just switch between stuff
2013-11-07T17:12:06 < Steffan-> whoa, diptrace website is too fancy now
2013-11-07T17:12:35 < gxti> dongs: example?

2013-11-07T17:13:00 < fbs> ah
2013-11-07T17:13:20 < gxti> +-* work well enough but it might be nice to hotkey individual layers

2013-11-07T17:16:37 < fbs> got to press L and go the the 3th tab

2013-11-07T17:19:59 < dongs> tho i guess thats just getting used to the shit.
2013-11-07T17:20:03 < fbs> nfi, i usually have silk off
2013-11-07T17:20:05 < dongs> can always flip with vb
2013-11-07T17:20:42 < dongs> but still
2013-11-07T17:20:46 < dongs> in transparent mode its ALL transparent
2013-11-07T17:20:47 < fbs> i use the schematic editor to select & place parts, and do the silk in the last step
2013-11-07T17:20:54 < dongs> can it highlight *current* layer more?

2013-11-07T21:51:14 < jpa-> it's somewhat annoying that the CPU stops for 4 milliseconds when writing EEPROM on stm32l151

2013-11-07T22:01:38 < emeb> that blows. Doesn't even let you go off and do other things? Or do you have background processes that try to access the EEPROM during the write?
2013-11-07T22:02:45 < zyp> eeprom is probably just a part of the flash stuff
2013-11-07T22:03:03 < zyp> so I guess writing eeprom blocks entire flash
2013-11-07T22:03:21 < emeb> oh - so they're driving them with the same control logic, just with different memory cells that have more endurance?
2013-11-07T22:03:47 < zyp> I suspect so
2013-11-07T22:03:56 < jpa-> yeah.. i guess flash and eeprom have the same AHB interface so when eeprom is busy the flash cannot be accessed
2013-11-07T22:05:20 < jpa-> well, i guess i'll just keep everything in ram and dump it back just when very idle
2013-11-07T22:05:48 < zyp> it's only 4ms though :)
2013-11-07T22:13:23 < jpa-> enough to ruin all timing :)
2013-11-07T22:14:15 < Steffan-> so use some external eeprom
2013-11-07T22:14:21 < zyp> what are you doing that is that timing critical? :p
2013-11-07T22:15:37 < gxti> you can fly to the moon on 4ms
2013-11-07T22:15:43 < gxti> whatever that means
2013-11-07T22:17:25 < Steffan-> this is time by your ntp thingy gxti?
2013-11-07T22:17:32 < Steffan-> *timed
2013-11-07T22:17:55 < gxti> sure. i use an external eeprom anyway, and it's only read on startup :P
2013-11-07T22:18:16 < gxti> and just ip address crap
2013-11-07T22:18:39 < Steffan-> i was more questioning the accuracy of it :P
2013-11-07T22:19:22 < gxti> 4ms is quite a lot, i think even an arduino can handle it

2013-11-08T20:01:51 < emeb> Anyone interested in doing some coding for $$?
2013-11-08T20:02:28 < emeb> Some outfit contacted me out of the blue and needs help writing a routine to flash load an F100 part via the JTAG/SWD pins.
2013-11-08T20:04:11 < PaulFertser> emeb: wait, what? Isn't it implemented already in BMP and openocd etc?
2013-11-08T20:04:39 < emeb> PaulFertser: Yeah - I pointed them at that code. I guess it looked too hard for them.
2013-11-08T20:04:51 < PaulFertser> :)
2013-11-08T20:05:09 < PaulFertser> emeb: but what do they actually want and what do they offer?
2013-11-08T20:05:29 < emeb> PaulFertser: pretty vague on both points.
2013-11-08T20:06:12 < emeb> Basically they've got a production test rig based on an F100 and they want to use it to flash load firmware into boards based on F100.
2013-11-08T20:07:58 < PaulFertser> Hm, sounds doable...
2013-11-08T20:08:22 < emeb> I could PM you contact info
2013-11-08T20:10:42 < Steffan-> A few days ago I used openocd again ( was a very long time ago i tried it ).. and a discovery board. I was kind of surprised by how well it worked :P
2013-11-08T20:10:44 < PaulFertser> emeb: if it's unclear how much they offer I'm probably out. Somebody else here can certainly be interested too.
2013-11-08T20:11:34 < emeb> PaulFertser: It's not that they're being cagey - they didn't say and I haven't asked.
2013-11-08T20:11:57 < emeb> Doesn't hurt to email them and see if they've got a firm offer.

2013-11-08T20:13:06 < PaulFertser> emeb: btw, their f100 is most probably just bitbanging lines, so it wouldn't be that easy actually, one would need to write an appropriate "jtag buffering" firmware for it...
2013-11-08T20:14:38 < emeb> PaulFertser: yes - it is bitbanging. I'm pretty sure that the BMP firmware handles that part, but buffering up the firmware load (either in RAM from a host or from a const array in flash) would likely be required.
2013-11-08T20:16:07 < PaulFertser> emeb: it's possible BMP wouldn't fit their f100 at all, and so would need to be run on host sending some higher-level commands (like jtag scan dr M move to state N)
2013-11-08T20:17:24 < Steffan-> but.. it's not that one needs all functionality from the bmp ..
2013-11-08T20:17:49 < emeb> PaulFertser: aye - the full BMP might not fit (the original is for an F102 / F103). But they don't need the full GDB interface and multi-proccessor support. Just the SWD/JTAG comm routines + F100 flash loader.
2013-11-08T20:17:52 < Steffan-> but gpl and crap doesn't make everyone happy.
2013-11-08T20:18:32 < PaulFertser> Steffan-: (gpl) thought about that but does it really prevent somebody from doing a derived work and sharing the result with the customer under GPL?
2013-11-08T20:18:41 < emeb> Steffan-: doubt that gpl & crap matters - sounds like the code they want isn't for end products. just a single production tester.
2013-11-08T20:18:42 < PaulFertser> I do not see how it can interfere here.
2013-11-08T20:18:49 < PaulFertser> Yes
2013-11-08T20:19:04 < PaulFertser> emeb: agreed

2013-11-08T20:21:59 < emeb> Sounds like a hardware upgrade is part of the issue - it's already designed and they don't want to change it.

2013-11-08T20:29:49 < PaulFertser> I think sometimes discussing solutions for imaginary projects might still be helpful thanks to some side-effect :)
2013-11-08T20:30:23 < Steffan-> side-effects like what?

2013-11-08T20:33:06 < emeb> who's "starting with solutions"?
2013-11-08T20:33:34 < emeb> I'm describing the problem space as I understand it from limited communication with this person.
2013-11-08T20:33:52 < emeb> since they didn't provide a "good project description".
2013-11-08T20:35:35 < emeb> Actually, in my experience doing contract work, a good project description is one of the hardest things to come by.
2013-11-08T20:35:48 < emeb> usually the customer doesn't actually know what they need.
2013-11-08T20:36:32 < emeb> they've got a vague idea of the end goal, but how to get there... *nada*.
2013-11-08T20:37:12 < jpa-> it's worse when they think they know what they need, and are wrong

2013-11-08T20:37:55 < Steffan-> Nah, perhaps "starting" wasn't the right word, but still .. still solutions for a totally vague problem :)
2013-11-08T20:38:02 < Steffan-> ( with no inside info )
2013-11-08T20:38:18 < jpa-> normal
2013-11-08T20:38:39 < Steffan-> Most of the time you do have some inside info about what they have and what they want.
2013-11-08T20:39:32 < jpa-> wasn't that clear, they have F100, want to load F100 :)
2013-11-08T20:40:08 < Steffan-> but i guess they do have some "system" that talks to the F100 loader stuff.
2013-11-08T20:40:09 < jpa-> but it is always fun when people get the hardware first and then start thinking about software
2013-11-08T20:40:51 < Steffan-> but this is all speculation and speculating sucks :P

2013-11-08T20:42:47 < Steffan-> ?
2013-11-08T20:44:08 < Steffan-> but F100 doesn't evne come with usb, does it?
2013-11-08T20:44:09 < emeb> Steffan-: AIUI this is a new product line with a new production tester
2013-11-08T20:44:31 < emeb> the engineer in charge designed the production tester w/o knowing the software issues.
2013-11-08T20:45:05 < emeb> He's been trying to get help from ST to do his flash loader, but apparently ST prefers to toss programming business to their distributors.
2013-11-08T20:45:15 < emeb> ie - they want him to buy pre-programmed devices.

2013-11-09T01:35:10 < ashfaq> Hi, I use the stm32 discovery board, and am now planning to design my own pcb for it. im looking out for any pointers i can get.
2013-11-09T01:35:45 < ashfaq> also, it would be good to know about progaming the stm using jtag on a self made board
2013-11-09T01:38:22 < dongs> there;s a appnote by ST
2013-11-09T01:38:27 < dongs> scchematic checklist.
2013-11-09T01:39:25 < ashfaq> oh dint know about that. Thanks will look it up
2013-11-09T01:40:20 < ashfaq> do you have the link for it?
2013-11-09T01:40:36 < dongs> looking. ive seen it before because it talks about pin compatibility between f1/f2/f4 series and shit like that
2013-11-09T01:40:45 < dongs> crystal calcultion, where to put vcap shit and bla
2013-11-09T01:42:24 < dongs> god damn google is worthless now
2013-11-09T01:42:35 < dongs> probably cuz st's site is worthless.
2013-11-09T01:43:05 < gxti> speaking of worthless, it's time to buy some more gps modules (just kidding they're awesome)
2013-11-09T01:43:08 < ashfaq> found it for stm32f0 and f3 series
2013-11-09T01:43:22 < dongs> http://www.st.com/st-web-ui/static/active/en/resource/technical/document/application_note/CD00164185.pdf
2013-11-09T01:43:24 < ashfaq> but nothing for stm32f4 yet
2013-11-09T01:43:25 < dongs> F1
2013-11-09T01:43:34 < dongs> 'getting started with..." design guide
2013-11-09T01:43:44 < dongs> go to the part# you need off st.com and check 'design resources' tab
2013-11-09T01:44:30 < dongs> 90% of the stuff from the F1 doc will apply there
2013-11-09T01:44:36 < dongs> and then lookup one of the hardware migration shtis
2013-11-09T01:44:38 < dongs> shits
2013-11-09T01:44:42 < dongs> that talks about pin compatible and bla
2013-11-09T01:44:45 < dongs> should be all there
2013-11-09T01:45:03 < ashfaq> all the app notes for f4 are here
2013-11-09T01:45:04 < ashfaq> http://www.st.com/stonline/stappl/resourceSelector/app?page=fullResourceSelector&doctype=application_note&SeriesID=1577
2013-11-09T01:45:11 < ashfaq> thanks I shall do that
2013-11-09T01:45:38 < dongs> no thats not all of them
2013-11-09T01:45:44 < dongs> there's a lot more if you look up from individual chip part#
2013-11-09T01:46:37 < ashfaq> yes, these are the topics for all diff parts
2013-11-09T01:47:37 < dongs> i dont see the F1 hardware design guide i just pasted
2013-11-09T01:47:37 < dongs> so no

2013-11-09T16:21:27 < karlp> don't you have srst or something to make it come alive?
2013-11-09T16:21:53 < karlp> oocd should be able to do hit srst and then do a couple of memory writes to turn power on?

2013-11-09T16:30:22 < jpa-> karlp: nope, never really had much use for the discovery boards; i prefer to do my own boards even for protos
2013-11-09T16:31:51 < karlp> fair enough
2013-11-09T16:32:23 < karlp> probably explains why most of your stuff actually gets done eventually too,
2013-11-09T16:39:38 < jpa-> also explains why some of my stuff ends up hardware complete but no software to run it
2013-11-09T16:40:11 < jpa-> hmm, looks like i can get decent resolution from the stm32l151 temperature sensor by oversampling (without oversampling it would only be about 1°C resolution)   http://kapsi.fi/~jpa/stuff/pix/temperature.png
2013-11-09T16:48:39 < Steffan-> but how correct is it?
2013-11-09T16:48:52 < jpa-> not very

2013-11-09T16:49:16 < jpa-> but i'm mostly interested about gradients
2013-11-09T16:53:42 < karlp> I thought factory calibration was missing anyway?

2013-11-09T17:03:16 < ashfaq_> hello everyone, can someone tell me which controller, STM32F1 or STM32F4 is better documented. I am starting to use the STM for my project this year and not able to decide between the two

2013-11-09T17:04:22 < zyp> I'd say they are equally well documented, and that's a silly point to use for deciding
2013-11-09T17:04:32 -!- BrainDamage [~BrainDama@dynamic-adsl-78-12-228-250.clienti.tiscali.it] has joined ##stm32
2013-11-09T17:05:11 < zyp> why are you choosing between F1 and F4? why aren't you considering other options like F3?

2013-11-09T17:06:30 < zyp> what are you making? how much performance do you need? will you perform calculations on floating point numbers? how much do you care about price? what kind of connectivity do you need?
2013-11-09T17:07:55 < ashfaq_> working on making a distributed node controller for an automotive application, performance mainly intererms of sampling various sensors at different rates. Floating point will not be used
2013-11-09T17:08:01 < ashfaq_> I want CAN mainly
2013-11-09T17:08:13 < ashfaq_> price is least priority
2013-11-09T17:08:30 < zyp> ok
2013-11-09T17:08:37 < zyp> will you use usb?
2013-11-09T17:09:13 < ashfaq_> only for debugging initially, but i plan to develop my own pcb and use it with stlink
2013-11-09T17:10:18 < zyp> I'm asking because certain families can't use both can and usb at the same time
2013-11-09T17:10:33 < zyp> because they share some internals
2013-11-09T17:10:53 < ashfaq_> yes, i did notice that. this problem exists in F1
2013-11-09T17:11:04 < zyp> yes, and also F3 I believe
2013-11-09T17:11:15 < zyp> F2 and F4 has fully independent usb and can
2013-11-09T17:11:30 < zyp> so you'd likely want to go with either of those
2013-11-09T17:12:11 < zyp> F4 is just a faster F2 with FPU, you can probably pick either depending on availability and price
2013-11-09T17:12:24 < zyp> since you're not concerned about price, I'd suggest just going with F4
2013-11-09T17:13:45 < zyp> I saw you were asking yesterday about what you needed to do to design a board for F4
2013-11-09T17:14:11 < ashfaq_> hmmm yes, i too was thinkin abt the F4, im jst a bit skeptical about development time. the one with more documentation is preferred
2013-11-09T17:14:19 < ashfaq_> yes, i was
2013-11-09T17:14:37 < zyp> I don't believe there is a significant difference in amount of documentation
2013-11-09T17:14:52 < fbs> you can also use the disco board schematic as reference
2013-11-09T17:15:10 < zyp> how much experience do you have with pcb design/digital circuits?
2013-11-09T17:15:55 < ashfaq_> I have decided to go for the F4 but it is an over kill for my application, so need to give a satisfactory explanation to my team regarding it. Since its a disttributed node architecture there is no need to add extra computational power in each node
2013-11-09T17:16:21 < fbs> then use the f2?
2013-11-09T17:16:45 < ashfaq_> i have quite some experience with designing boards, I have made about 10 different boards with the Arduino platform
2013-11-09T17:17:10 < ashfaq_> yes i will look into F2 now. Documentation was my only concern, well i think all are equally documented
2013-11-09T17:17:14 < zyp> overkill is no disadvantage, as long as you have enough power, having extra doesn't hurt
2013-11-09T17:17:41 < fbs> might be possible to go from f4 to f2, i think most of the peripherals are the same
2013-11-09T17:18:01 < zyp> F2 and F4 is pretty much the same chip, the only difference is max speed and floating point
2013-11-09T17:18:04 < ashfaq_> yep. thats something people in electronics know. when you need to explain it to a not so tech person its a problem
2013-11-09T17:18:27 < ashfaq_> hmm i hadnt looked at the f2 will look at it now
2013-11-09T17:19:35 < ashfaq_> Is there a development board for f2?
2013-11-09T17:19:41 < zyp> no
2013-11-09T17:20:18 < zyp> but I believe all code for f2 should run unmodified on f4
2013-11-09T17:20:30 < ashfaq_> yes seems so.

2013-11-09T17:20:38 < zyp> so if you're going to pick either of those, you can prototype on f4 discovery

2013-11-09T22:37:33 < jpa-> hmm, strange problem with stm32l1 adc and chibios driver.. it never triggers the DMA complete interrupt, even though the DMA channel is enabled and CNDTR has gone to 0
2013-11-09T22:38:34 < trepidaciousMBR> And DMA interrupt is enabled?
2013-11-09T22:43:43 < jpa-> hmm, have to check when i get that crash again.. i also get another kind of crash and i'm debugging both in parallel :P
2013-11-09T22:44:20 < jpa-> seems to be somehow related to running at low clock freq (1MHz)
2013-11-09T22:47:43 < trepidaciousMBR> That's pretty low :)

2013-11-09T23:36:08 < prattmic> Does anyone know of a way to atomically read multiple timer counters in an F4?
2013-11-09T23:36:51 < prattmic> I have a slave timer incrementing on the update event of the master, and would like to read the combined value of both timers?
2013-11-09T23:37:14 < prattmic> The only thing I can think of is stopping the master timer, but then it misses ticks, of course
2013-11-09T23:38:40 < jpa-> if one timer increments fast and other increments slow, you can always do the dual-read trick
2013-11-09T23:39:52 < jpa-> (as long as you can assume that the slower timer doesn't increment twice during your reading)
2013-11-09T23:40:28 < jpa-> http://stackoverflow.com/a/17629917/914716  like this
2013-11-09T23:41:24 < gxti> and here's mine, although my upper 'timer' is a software variable so it's a bit different: https://github.com/mtharp/laureline-firmware/blob/master/src/ppscapture.c#L82
2013-11-09T23:42:14 < gxti> same general concept though
2013-11-09T23:42:53 < gxti> samples the low timer twice, if it went backwards then try again
2013-11-09T23:43:23 < prattmic> jpa-: gxti: Yeah, that will work, thanks

2013-11-10T00:01:38 < jpa-> http://paste.dy.fi/weI/plain   this looks quite weird to me
2013-11-10T00:06:28 < zyp> what am I looking at?
2013-11-10T00:06:54 < gxti> a computer monitor, probably
2013-11-10T00:07:01 < zyp> ah, I missed the first line :p
2013-11-10T00:08:23 < jpa-> unfortunately i can only get it happen when i have a bunch of other tasks running, so they fill up the chibios trace buffer etc. pretty quick
2013-11-10T00:09:07 < zyp> looks like a scheduler bug
2013-11-10T00:09:22 < jpa-> very much, but i would be very surprised to find a scheduler bug in chibios
2013-11-10T00:09:45 < zyp> why?
2013-11-10T00:10:27 < jpa-> it seems pretty well tested and widely enough used.. and the core is so small that it would be surprising for a bug to be there
2013-11-10T00:10:39 < jpa-> whereas the HAL surely contains bugs.. but i don't think any of them could cause this
2013-11-10T00:12:20 < zyp> well, either it's a scheduler bug, or something is abusing some scheduler API, perhaps calling it from a context it's not supposed to be called from, causing a race condition or re-entering of non-reentrant code or something like that
2013-11-10T00:13:05 < jpa-> yeah.. could be abuse, could be something writing to random memory locations, could be some other crazy stuff
2013-11-10T00:20:33 < jpa-> hmm.. i wonder if i maybe have messed up interrupt priorities somehow..
2013-11-10T00:22:07 < jpa-> chibios uses BASEPRI to implement system lock zones.. if i somehow have an interrupt higher priority than that, it would ignore system lock and could mess stuff

2013-11-10T00:25:13 < gxti> i think when i first started i set something TOO high priority and it was treated specially and screwed up hard
2013-11-10T00:25:54 < jpa-> though chibios seems to #error against that..
2013-11-10T00:28:23 < gxti> i think it was CORTEX_PRIORITY_SVCALL
2013-11-10T00:29:12 < gxti> BASEPRI being related. i never looked too closely into using them, i just know it bit me
2013-11-10T00:37:28 < jpa-> http://paste.dy.fi/GZE/plain   can somebody double-check me.. it appears that all interrupts are at priority 0?!?
2013-11-10T00:40:16 < zyp> try 0xe000e400
2013-11-10T00:41:02 < zyp> according to my code that's where IPR0 is
2013-11-10T00:42:21 < jpa-> aha, yeah, that shows correct values
2013-11-10T00:43:31 < jpa-> got confused by the manual:  "The base address of the main NVIC register block is 0xE000E100."    but the offset for IPR is not counted from the main register block but from 0xe000e000 :P
2013-11-10T00:44:17 < zyp> that's because the SCB is part of the NVIC block and sits below 0x100 :p

2013-11-10T11:08:15 < dongs> redo your board

2013-11-10T16:02:42 < dongs> Each ALARMclock is hand assembled with love. Including labor and materials for the enclosure each clock costs nearly $100 to produce. The screen consists of four resourcefully interconnected 8x8 LED display units and a stock Raspberry Pi processor. With your help, sourcing a higher-bandwidth 8x32 display module and a more specialized processor would create efficiencies that would help us lower total cost of each clock to under $50.

2013-11-10T17:10:53 < dongs> i think once wdg is started you only stop it by resetting
2013-11-10T17:12:03 < gxti> it's not disabling the watchdog, just pausing it when debugger is attached. in your real pro tools it's probably just a checkbox.

2013-11-10T17:43:32 < gxti> the iwdg register is, the lock register that i may or may not actually have to use is listed under ETM. now i'm curious.
2013-11-10T17:43:51 < zyp> not under DBGMCU?
2013-11-10T17:44:12 < gxti> the iwdg register is DBGMCU_CR
2013-11-10T17:44:26 < zyp> ah, right
2013-11-10T17:46:12 < gxti> looks like the lock reg crap is unnecessary after all
2013-11-10T17:46:57 < gxti> crap, and NOW I notice that DBGMCU is in stm32f10x.h too. shouldn't write code before noon.
2013-11-10T17:47:32 < gxti> for some reason i was really fixated on that ETM thing and looked for it first then decided that i couldn't do what i needed to with the headers.
2013-11-10T17:47:39 < gxti> forgot to look for DBGMCU.

2013-11-10T22:00:31 < fbs> hmm
2013-11-10T22:01:06 < fbs> so i had a 4 relays driven by a i2c io expander, all powered + signal through a 1meter utp cable
2013-11-10T22:01:43 < fbs> every time the relay switched the flatcable between my board and the raspberry pi got mad
2013-11-10T22:02:37 < fbs> and just starts receiving bogus data, if i send 2 bytes it receives 2 bytes (dma & no spi errors) but the data would be totally different

2013-11-11T00:13:27 < fbs> with seprate controller or is there some magic trick?

2013-11-11T00:15:57 < Steffan-> but i dont see why one would add a programmer to their board instead of just a connector ( unless it's some fancy dev board )
2013-11-11T00:16:19 < Steffan-> ask Tectu ;)
2013-11-11T00:18:07 < fbs> so i can remote debug lol
2013-11-11T00:19:08 < fbs> maybe i should just find a good bootloader
2013-11-11T00:19:23 < Tectu> how does one exactly debug using a bootloader?

2013-11-11T00:26:51 < Steffan-> you can always solder osme wires to the correct pads/pins :P
2013-11-11T00:26:57 < zyp> Tectu, how would you do initial programming then?
2013-11-11T00:27:04 < zyp> :p
2013-11-11T00:27:44 < zyp> I'm pretty happy with tag connect for that
2013-11-11T00:27:58 < Tectu> zyp, what monies does one use for tag connect?
2013-11-11T00:28:03 < Tectu> need*
2013-11-11T00:28:09 < fbs> 32
2013-11-11T00:28:34 < zyp> dunno, I was annoyed by expensive shipping
2013-11-11T00:28:57 < fbs> digikey has them
2013-11-11T00:29:07 < zyp> not the cortex one
2013-11-11T00:29:13 < zyp> at least not when I got mine
2013-11-11T00:30:31 < fbs> tagconnect is just cable right?
2013-11-11T00:30:47 < gxti> a fancy one
2013-11-11T00:31:09 < zyp> fbs, yes, but they come in different editions with different connectors on the other end
2013-11-11T00:31:30 < fbs> figured i could just make an adapterboard
2013-11-11T00:31:44 < zyp> I figured I didn't want to make an adapter board

2013-11-11T00:35:10 < fbs> loooool
2013-11-11T00:36:09 < Steffan-> on ebay they are pretty cheap not?
2013-11-11T00:36:17 < zyp> but I think it has more or less paid for itself already, judging by the price of the connectors I'd buy otherwise: http://www.digikey.com/product-detail/en/20021521-00010T1LF/609-4054-ND/2414951
2013-11-11T00:37:27 < fbs> why not throughole?

2013-11-11T00:38:02 < Tectu> throughhole? lol?
2013-11-11T00:38:08 < Tectu> what's that? something to eat?

2013-11-11T00:40:31 < zyp> that might be, but I don't want to waste my time soldering shit by hand when I can just reflow the pth connector
2013-11-11T00:41:02 < zyp> I'm pretty sure my time is expensive enough to make up for that difference in price :p

2013-11-11T00:43:01 < Laurenceb_> are tagconnect connectors available?

2013-11-11T00:43:37 < zyp> you mean just the connector, without the cable?
2013-11-11T00:43:50 < zyp> I believe they are just sold as complete cables
2013-11-11T00:45:14 < Laurenceb_> ok, where?
2013-11-11T00:45:38 < Laurenceb_> just from tag-connect.com?

2013-11-11T00:45:56 < Laurenceb_> oh digikey has them, cool

2013-11-11T00:46:29 < Laurenceb_> omfg the price
2013-11-11T00:46:30 < zyp> except they don't have the TC2030-CTX
2013-11-11T00:48:24 < fbs> mcp got the weird rj47 connector right?
2013-11-11T00:48:59 < zyp> yep
2013-11-11T00:49:09 < zyp> http://www.tag-connect.com/TC2030-CTX-NL <- this is the one I got
2013-11-11T00:49:31 < Laurenceb_> ah, without the big holes
2013-11-11T00:49:38 < zyp> and I think I figured that none of the distributors would be cheaper for me, so I just ordered directly
2013-11-11T00:49:44 < gxti> did you get the clip as well?
2013-11-11T00:49:48 < zyp> yep
2013-11-11T00:49:52 < gxti> how well does that work?
2013-11-11T00:50:08 < zyp> only used the clip once, seems to work fine
2013-11-11T00:50:37 < Laurenceb_> they have all the adaptors
2013-11-11T00:50:39 < Laurenceb_> looks good
2013-11-11T00:52:03 < zyp> I'm mostly using it for flashing bootloaders, so I have a single gdb alias to do swd scan, attach, flash and detach, so I just hold it down, press a button, and let it go again after a second or two
2013-11-11T00:53:30 < zyp> http://paste.jvnv.net/view/ghbGF <- flashing a batch of boards looks like this
2013-11-11T00:59:53 < fbs> which bootloader do you use?
2013-11-11T01:00:20 < zyp> I wrote my own
2013-11-11T01:00:28 < fbs> still looking for a way to let my rpi flash my f0
2013-11-11T01:00:45 < zyp> http://cgit.jvnv.net/arcin/tree/bootloader.cpp <- it's HID based, pretty simple stuff
2013-11-11T01:01:02 < fbs> ah
2013-11-11T01:01:40 < zyp> 68-138 is the flashing stuff, 140-179 is the HID frontend
2013-11-11T01:02:24 < zyp> http://cgit.jvnv.net/arcin/tree/bootloader.cpp?id=9a09653 <- I wrote a DFU frontend first, which also works
2013-11-11T01:03:39 < zyp> but I ended up not using it, to avoid having windows complaining about missing driver for the DFU interface
2013-11-11T01:03:49 < zyp> the whole point of using HID is to keep it driverless

2013-11-11T11:09:35 < dongs> thats a lot of screws
2013-11-11T11:10:06 < dongs> better use i2c gpio expander shield
2013-11-11T11:10:09 < GargantuaSauce> yeah it was....kind of tedious to assemble
2013-11-11T11:10:10 < GargantuaSauce> heh
2013-11-11T11:11:00 < GargantuaSauce> i think i'll stick with shift registers!
2013-11-11T11:14:25 < dongs> not pro enough
2013-11-11T11:14:50 < dongs> you need raspberrypi and I2C GPIO shield
2013-11-11T11:22:13 < GargantuaSauce> how about a compromise
2013-11-11T11:22:18 < GargantuaSauce> bluetooth interface for each leg?
2013-11-11T11:23:21 < Thorn> ardweeeeno for each leg
2013-11-11T11:23:41 < Thorn> that would be "in"
2013-11-11T11:24:11 < Thorn> with bitbanged pwm for the servos (if they're pwm controlled)
2013-11-11T11:25:32 < GargantuaSauce> oh they are
2013-11-11T11:25:49 < GargantuaSauce> standard 1-2ms bullshit (well 0.5-2.5)
2013-11-11T11:26:10 < GargantuaSauce> really wish a more sane interface with position feedback was available at that sort of pricepoint
2013-11-11T11:26:34 < GargantuaSauce> but adding openservo or something would triple the price
2013-11-11T11:27:39 < Thorn> how much did those 24 servos cost you btw?

2013-11-11T14:17:51 < zyp> problem: stop bit set too late, resulting in an extra byte being read, that'll stay left over and get read as the first byte of the next transaction
2013-11-11T14:18:03 < zyp> so all my i2c reads got one byte skewed

2013-11-11T14:41:17 < dongs> is this in laks?

2013-11-11T14:50:39 < Robint91> AES or RSA or ...
2013-11-11T14:50:43 < Robint91> mhh
2013-11-11T14:50:48 < Robint91> I think AES
2013-11-11T14:50:51 < fbs> aes and rsa are different things
2013-11-11T14:50:55 < Robint91> RSA is public ....
2013-11-11T14:51:11 < fbs> and aes is sym
2013-11-11T14:51:19 < dongs> some STM32s have aes crypto block
2013-11-11T14:51:20 < Robint91> indeed something sym is better
2013-11-11T14:51:32 < dongs> if  you dont really care you can always use TEA
2013-11-11T14:51:41 < fbs> built in aes is indeed fast and minimal code size
2013-11-11T14:53:00 < dongs> just depends how secret you want it to be .
2013-11-11T14:59:49 < zyp> I hear rot13 is pretty fast
2013-11-11T15:11:44 < zyp> dongs, any news on amtek?
2013-11-11T15:12:34 < dongs> can probably buy ~100pcs as samples, but MOQ is 1k for production and they've got not distibutors/etc. probably better to find a replacement.
2013-11-11T15:13:20 < dongs> also, realmoney
2013-11-11T15:13:32 < dongs> see if you can find some compatible part #s from various manufacturers and I'll run them by china again

2013-11-11T15:14:28 < dongs> wat
2013-11-11T15:16:20 < Steffan-> BBC censored the photo .. there is actually a video where you see him with the nail. Not sure if i really wanted to see that though.
2013-11-11T15:18:07 < zyp> 12:06:48 < zyp> apparently other options are "Cen Link TPF0-24050-0111" or "Grad Conn BB02-CQ502-K08-000000", but I haven't seen them in stock anywhere
2013-11-11T15:18:16 < dongs> yeah i had htem try those.
2013-11-11T15:18:16 < zyp> dongs, so those would be compatible

2013-11-11T15:19:51 < zyp> dongs, so neither those two nor the Harwin ones on digikey are available?
2013-11-11T15:21:19 < dongs> yeah
2013-11-11T15:21:35 < dongs> how many would you need of amtek?
2013-11-11T15:21:53 < dongs> like i said, it could be a one-time buy of some sample-ish qty but it probably wont happen again and it would have to be real money
2013-11-11T15:22:26 < dongs> i have price somewehre um.. sec
2013-11-11T15:22:29 < zyp> currently I need enough for the ~30 boards I'm interested in, can probably do 100 if they are cheap enough
2013-11-11T15:22:31 < dongs> i think it was something liek 14twd
2013-11-11T15:23:21 < dongs> PS3BM20-225GBOOT-U..1.27, SMT, H=2.0MM, 2X25P, ., .., .CAP, .., ROHS + NYLON 6TPCS14.5MOQ:1K
2013-11-11T15:23:43 < dongs> 14.5
2013-11-11T15:23:56 < zyp> so like $.5 each
2013-11-11T15:23:59 < dongs> +-.
2013-11-11T15:25:01 < dongs> it would look mega silly to do real money transfer for that shitty amount tho
2013-11-11T15:25:26 < dongs> and taiwanscam doesn't do scampal etc. i can probly ask some favors but it'd be last time, next time you'd be buying 1k :)
2013-11-11T15:28:53 < zyp> well, considering that the price for 1k there gets me 60-70 of the ones from digikey I don't think that's horrible :p

2013-11-11T15:30:25 < dongs> OK.
2013-11-11T15:30:44 < dongs> i had quote from them since like 5 days ago
2013-11-11T15:33:29 < zyp> yeah, 100 now would be fine at that price
2013-11-11T15:34:51 < dongs> k, i'll retweet the request again. not sure what they're gonna want for paying tho. we'll see.
2013-11-11T15:34:56 < dongs> will let you know

2013-11-11T23:18:16 < Laurenceb_> my code is - https://github.com/Laurenceb/STM32-Logger/blob/master/jtag/stm32loader.py
2013-11-11T23:18:51 < Laurenceb_> basically it needs to set a GPIO on the RN-42 to keep the power supply enabled
2013-11-11T23:19:15 < Laurenceb_> any idea why there is a "Go" command?
2013-11-11T23:19:19 < Laurenceb_> why not just reset?

2013-11-11T23:21:41 < bsdfox> I'd just use a p-channel fet or something to toggle power to the bluetooth device and add it to your startup routine
2013-11-11T23:22:00 < Laurenceb_> yeah i do that already
2013-11-11T23:22:03 < Laurenceb_> its really weird
2013-11-11T23:22:23 < Laurenceb_> ive removed line 490
2013-11-11T23:22:24 < Laurenceb_> https://github.com/Laurenceb/STM32-Logger/blob/master/jtag/stm32loader.py#L490
2013-11-11T23:22:24 < bsdfox> the stm32 is working fine but the bluetooth isn't?
2013-11-11T23:22:28 < Laurenceb_> yes
2013-11-11T23:22:31 < Laurenceb_> heh
2013-11-11T23:22:38 < Laurenceb_> its more of a bluetooth issue :P
2013-11-11T23:22:38 < bsdfox> I wonder if it's powering by the TX line
2013-11-11T23:22:44 < Laurenceb_> yes, me too
2013-11-11T23:22:53 < Laurenceb_> if i power cycle the board it works fine once
2013-11-11T23:23:08 < bsdfox> maybe set all pins to input and pause a sec while you toggle power
2013-11-11T23:23:12 < Laurenceb_> im wondering if its leaching power somewhere
2013-11-11T23:23:40 < Laurenceb_> yeah
2013-11-11T23:24:10 < Laurenceb_> the second time i run the loader on a powered board, it cant get into CMD mode on the bluetooth a second time
2013-11-11T23:24:15 < bsdfox> are RX/TX the only gpio connected to the bluetooth?
2013-11-11T23:24:17 < Laurenceb_> very odd - it works once
2013-11-11T23:24:28 < Laurenceb_> no, there GPIO onto the BOOT and reset pins
2013-11-11T23:24:37 < Laurenceb_> so it can reflash the stm32
2013-11-11T23:25:02 < bsdfox> those are inputs on the stm32 though
2013-11-11T23:25:31 < bsdfox> if you manually toggle power does the bluetooth reset properly? I bet it's powering off the TX line
2013-11-11T23:25:41 < bsdfox> probably goes into some fucked up brownout state

2013-11-11T23:25:52 < Laurenceb_> yeah
2013-11-11T23:26:02 < Laurenceb_> its a battery powered datalogger
2013-11-11T23:26:13 < Laurenceb_> so the stm32 is powered all the time off an LDO
2013-11-11T23:26:24 < Laurenceb_> everything else is powered down in sleep mode
2013-11-11T23:26:30 < Laurenceb_> so what happens is:
2013-11-11T23:26:49 < Laurenceb_> 1) plug battery in, connect to bluetooth and run flashing code
2013-11-11T23:26:59 < Laurenceb_> 2) it flashes ok and powers down
2013-11-11T23:27:13 < Laurenceb_> 3) i turn it on it powers and powers down ok
2013-11-11T23:27:40 < Laurenceb_> 4) try flashing again, bluetooth can connect and enter CMD mode, flash the stm32 ok
2013-11-11T23:27:54 < Laurenceb_> 5) when it tries to exit, bluetooth wont enter command mode
2013-11-11T23:27:58 < Laurenceb_> its really weird
2013-11-11T23:28:23 < Laurenceb_> https://github.com/Laurenceb/STM32-Logger/blob/master/jtag/stm32loader.py#L80
2013-11-11T23:28:43 < Laurenceb_> "$$$" is not acknowledged
2013-11-11T23:28:58 < Laurenceb_> power cycling fixes the problem
2013-11-11T23:30:02 < bsdfox> and your stm32 code cycles power after boot?
2013-11-11T23:30:10 < Laurenceb_> yeah
2013-11-11T23:30:20 < Laurenceb_> it cycles bluetooth power
2013-11-11T23:31:02 < bsdfox> I'd try to make sure TX was disabled/set as input and maybe add a longer delay?
2013-11-11T23:31:26 < bsdfox> sounds like the bluetooth doesn't reset properly.. maybe your fet isn't working as expected also/
2013-11-11T23:35:22 < Laurenceb_> yeah :-S
2013-11-11T23:35:32 < Laurenceb_> its not a fet - im using the EN pin on a vreg
2013-11-11T23:35:59 < bsdfox> stick a scope on it and see what actually happens :)
2013-11-11T23:37:58 < Laurenceb_> interestingly if verify is removed it works
2013-11-11T23:43:19 < bsdfox> seems like a neat project
2013-11-11T23:44:01 < Laurenceb_> if it can be made to work :P
2013-11-11T23:45:07 < bsdfox> well it seems that power cycling fixes the problem.. it might not be the most elegant solution but it's certainly something that can be implemented
2013-11-11T23:46:30 < bsdfox> I wonder if you're resetting the bluetooth twice after programming (once when the stm32 resets.. en pin goes to input, once on purpose in code) and it gets caught in a weird state
2013-11-11T23:46:41 < Laurenceb_> part of the problem is probably that the bluetooth kills itself
2013-11-11T23:46:52 < Laurenceb_> when it sets its GPIO low
2013-11-11T23:49:08 < bsdfox> yeah that sounds like a problem
2013-11-11T23:50:17 < Laurenceb_> so it receives command to set GPIO and then loses power as soon as it sets it low
2013-11-11T23:52:07 < Laurenceb_> https://github.com/Laurenceb/STM32-Logger/blob/master/jtag/stm32loader.py#L150
2013-11-11T23:52:17 < Laurenceb_> so it gets an error there the first time it runs
2013-11-11T23:52:23 < Laurenceb_> later times it never gets that far
2013-11-11T23:54:11 < bsdfox> Laurenceb_, does it crash if gpio3 isn't connected to anything?
2013-11-11T23:54:44 < Laurenceb_> what do you mean crash?
2013-11-11T23:55:09 < Laurenceb_> when the stm32 is in bootloader mode, without gpio3 the whole board will power down
2013-11-11T23:55:10 < bsdfox> you say the bluetooth 'kills itself' when GPIO3 is set low

2013-11-11T23:55:21 < Laurenceb_> so gpio keeps the pmu enabled
2013-11-11T23:55:52 < bsdfox> oh so your ldo is shared on the stm32 and the bluetooth?
2013-11-11T23:56:14 < Laurenceb_> yes
2013-11-11T23:56:19 < Laurenceb_> its a 3.3v ldo
2013-11-11T23:56:27 < Laurenceb_> there is a 3v supply for just the stm32
2013-11-11T23:56:35 < Laurenceb_> that kicks in when the 3.3v is lost
2013-11-11T23:56:50 < Laurenceb_> its for standby/long duration logging use
2013-11-11T23:57:15 < bsdfox> hmm I'd have to see a schematic of the power setup to understand I think
2013-11-11T23:57:29 < bsdfox> GPIO3 goes to reset on STM32?
2013-11-11T23:57:39 < Laurenceb_> its messy
2013-11-11T23:57:41 < Laurenceb_> no
2013-11-11T23:57:48 < bsdfox> and then when EN isn't driven high the ldo shuts off?
2013-11-11T23:58:45 < Laurenceb_> http://i.imgur.com/a6hxswc.png
2013-11-11T23:58:49 < Laurenceb_> yes
2013-11-11T23:58:53 < Laurenceb_> but i have an idea now
2013-11-11T23:59:02 < Laurenceb_> i can force the LDO EN low
2013-11-11T23:59:06 < Laurenceb_> using the stm32 gpio
2013-11-11T23:59:19 < Laurenceb_> it does mean the board can be bricked tho...
--- Day changed Tue Nov 12 2013
2013-11-12T00:00:09 < Laurenceb_> R41 is 220ohm, so i can force the power en low on boot, and use the "Go Command" after verify
2013-11-12T00:03:30 < bsdfox> I guess I'm not sure why your bluetooth module has to disable power instead of just toggle nRST
2013-11-12T00:03:50 < bsdfox> but I didn't fully comprehend the schematic
2013-11-12T00:04:06 < Laurenceb_> heh yeah its a mess
2013-11-12T00:04:35 < Laurenceb_> bluetooth has t enable power, or the power will be disabled when the stm32 enters reset
2013-11-12T00:04:53 < bsdfox> wouldn't a pullup resistor on EN fix that?
2013-11-12T00:05:09 < Laurenceb_> i want it to default to off, for safety
2013-11-12T00:05:16 < Laurenceb_> i think i might have a solution
2013-11-12T00:05:25 < bsdfox> cool. let me know how it works
2013-11-12T00:05:31 < Laurenceb_> the STM32 forces PWREN low for a few ms on boot
2013-11-12T00:05:41 < Laurenceb_> that will force a bluetooth reset each boot
2013-11-12T00:06:30 < Laurenceb_> atm the bluetooth can get into the weird mode when GPIO3 is always high and bluetooth command mode is unresponsive after one programming cycle following a battery in/out power cycle

2013-11-12T00:36:28 < zyp> by the way, did you mean 0x20010000 or 0x20001000 ?
2013-11-12T00:36:35 < zyp> (both are wrong)
2013-11-12T00:36:49 < johannes___> 0x20010000
2013-11-12T00:36:59 < zyp> ok, then try 0x20010001
2013-11-12T00:37:52 < johannes___> odd? Ok I'll try...
2013-11-12T00:38:19 < zyp> yes, that bit is used to indicate mode, arm or thumb
2013-11-12T00:38:22 < zyp> and 1 is thumb
2013-11-12T00:38:34 < zyp> 0 will fault since the cpu doesn's support arm mode
2013-11-12T00:39:32 < johannes___> ok that solves it
2013-11-12T00:40:15 < johannes___> and  I understand this arm/thumb fuzz a bit better
2013-11-12T00:40:18 < johannes___> great!
2013-11-12T00:41:17 < johannes___> spend already half a day on it...

2013-11-12T04:32:17 < upgrdman> iirc there's software that works with some wifi cards and lets you get a crude spectrum analyzer for the 2.4g band. what's it called?

2013-11-12T05:02:41 < dongs> which is a good thing
2013-11-12T05:10:58 < PaulFertser> upgrdman: ath9k devices support that, just search for "ath9k spectrum analizer" or something like that.
2013-11-12T05:11:12 < upgrdman> ok thanks
2013-11-12T05:11:26 < upgrdman> i wonder what chipset MBP's use

2013-11-12T13:55:02 < baird> After a bit of walking about and seeing a few motorcycle dealers, I found a guy who offered to collect Postie with his Ute, and drive me across town to the 'AusPost contracter', and then let me fix the bike in his shop's shed.. Didn't have to reciprocate with oral sex, wither.
2013-11-12T13:56:24 < GargantuaSauce> so was it just the chain that broke
2013-11-12T13:57:40 < BrainDamage> can it stop insects and squirels yet?
2013-11-12T13:57:41 < baird> The tensioner-- what holds the rear axle in position. When that failed, the movement flicked the chain off the rear sprocket
2013-11-12T13:58:40 < Steffan-> How fast that bike goes baird?
2013-11-12T13:59:33 < baird> 65km/h, usual touring speed. Can get up to 85 in rare situations. :)

2013-11-12T14:00:06 < baird> I can reach down and get the bottle while riding.
2013-11-12T14:00:15 < karlp> you drove up the stuart from adelaide all the way?
2013-11-12T14:01:04 < baird> Nope. Newcastle -> Adelaide -> Nullarbour plain -> Geraldton (WA coast) -> Broome (sucked ass) -> Darwin.

2013-11-12T17:10:47 < talsit> stupid sanity-checking question, if a datasheet says "When !OE is 1", what actual voltage is at the pin, GND or V+?

2013-11-12T17:13:00 < jpa-> does it actually have ! there, or something else?
2013-11-12T17:13:21 < jpa-> but i would guess V+, even though it can be either depending on the quality of drugs ingested by the writer
2013-11-12T17:13:21 < talsit> a bar above the OE
2013-11-12T17:13:39 < talsit> quality or quantity?
2013-11-12T17:16:01 < zyp> !OE would be the name of the pin, so 1 would still be V+
2013-11-12T17:16:23 < jpa-> yeah, that's the logic i would find intuitive also
2013-11-12T17:16:29 < talsit> i've got an 8bit LED driver, with shift register, TLC5916, and i can just not get it to change to config mode

2013-11-12T19:25:10 < Laurenceb> i see debugging symbols

2013-11-12T19:28:16 < fbs> only if using gdb

2013-11-12T19:29:55 < fbs> DEBUG ?= 1, sets DEBUG to 1 only if DEBUG isnt defined yet. So you can do 'make DEBUG=0'

2013-11-12T19:43:14 < karlp> anyone know something like the mcp2210, usb to spi master? I thought ftdi had something like that too?
2013-11-12T19:43:38 < fbs> ft2232h should do usb to spi/jtag and other crap

2013-11-12T19:47:23 < karlp> was hoping for something that wasn't a qfp48, and cheaper,
2013-11-12T19:47:27 < karlp> just spi,
2013-11-12T19:47:40 < karlp> yeah, the 232h would work though.
2013-11-12T19:49:27 < zyp> stm32f1 too big/expensive?

2013-11-13T01:24:07 < Laurenceb_> is the DAC good enough for audio?
2013-11-13T01:24:15 < Laurenceb_> iirc someone got it playing failstep
2013-11-13T01:24:20 < Laurenceb_> ?
2013-11-13T01:24:59 < fbs> if it can do 20ksps its good enough
2013-11-13T01:25:39 < Steffan-> Laurenceb_, are you a audiophile?
2013-11-13T01:25:47 < Steffan-> No, then it's good enough.. ;)
2013-11-13T01:26:08 < fbs> even if you are, just use silver plugs
2013-11-13T01:26:18 < Steffan-> but i think emeb knows all about it.
2013-11-13T01:27:50 < Laurenceb_> i have a new invention
2013-11-13T01:28:07 < Laurenceb_> swearbox
2013-11-13T01:28:11 < Laurenceb_> you punch it
2013-11-13T01:28:49 < Steffan-> a dongsbox is more fancy.
2013-11-13T01:30:53 < Steffan-> Laurenceb_, this also uses the DAC https://www.youtube.com/watch?v=0ETyFmAMFjY ..
2013-11-13T01:31:16 < emeb> Laurenceb_: the 12-bit DAC on the STM32 parts is almost good enough for audio - depending on what you want to do with it.
2013-11-13T01:32:25 < emeb> 12-bits data will theoretically give you ~70dB SNR which is better than FM radio quality. The DAC isn't quite up to that, but it comes close.
2013-11-13T01:32:44 < Laurenceb_> ok
2013-11-13T01:32:46 < Laurenceb_> cool
2013-11-13T01:32:49 < emeb> The slew rate is rather low, so sampling at > 200kHz is not recommended.
2013-11-13T01:32:53 < Laurenceb_> yeah
2013-11-13T01:33:07 < emeb> but for audio rates (20kHz - 100kHz) it's fine.
2013-11-13T01:33:17 < Laurenceb_> i guess some logger type code
2013-11-13T01:33:33 < Laurenceb_> with wav or flac on a micro SD card
2013-11-13T01:33:39 < Laurenceb_> then you punch a button
2013-11-13T01:33:49 < Laurenceb_> and it shouts random insults
2013-11-13T01:33:56 < emeb> It would be perfect for that.
2013-11-13T01:34:12 < Steffan-> mp3 is easy enough Laurenceb_..
2013-11-13T01:35:01 < Laurenceb_> maybe
2013-11-13T01:35:07 < Steffan-> ST gives you the libs for it.
2013-11-13T01:35:11 < Laurenceb_> oh
2013-11-13T01:35:12 < Laurenceb_> lolz
2013-11-13T01:35:20 < Laurenceb_> thats helpful
2013-11-13T01:35:48 < Steffan-> They used some open source mp3 encoder/decoder i can't remember the name of

2013-11-13T08:29:01 < PaulFertser> dekar: the st eeprom emulation lib is almost ok, i have two things to say about it though.
2013-11-13T08:29:29 < emeb_mac> apparently "coolstoryb.ro is taken"
2013-11-13T08:29:35 < PaulFertser> dekar: first is that apparently those who wrote an application note for it were considerably less intellegent than those who developed most of the library.
2013-11-13T08:30:26 < PaulFertser> dekar: the way the eeprom variables declared is retarded. I can share my slightly modified version of the code if you're interested.
2013-11-13T08:31:25 < PaulFertser> Another is that they do not account for the failure scenario when device reboots repeatedely during "eeprom" page copy, that makes both pages full and no way to recover from it short of reflashing via jtag (but that must be a very very rare condition).

2013-11-13T09:39:55 < talsit> and the scope is not showing anything decent
2013-11-13T09:40:03 < talsit> replace the crystal?
2013-11-13T09:40:19 < PaulFertser> I'd replace the crystal itself then if you're sure the stm32 legs are soldered properly.
2013-11-13T09:40:39 < talsit> continuity is good
2013-11-13T09:47:14 < talsit> nope

2013-11-13T10:24:23 < dongs> PaulFertser: i thought the 4pin crystals can't be mismatched
2013-11-13T10:24:37 < talsit1> this crystal just doesn't work
2013-11-13T10:24:40 < talsit1> it may be the stm
2013-11-13T10:24:42 < dongs> i mean, pin1/pin3 is xtal, 2/4 is gnd/nc, so you can mount it either straight or 180
2013-11-13T10:24:49 < talsit1> but... i'll see
2013-11-13T10:25:09 < PaulFertser> dongs: it has a big nice visible dot on one side, and that side is NC, the crystal pins are on the opposite.
2013-11-13T10:25:49 < dongs> PaulFertser: in a 3225 4pin package?
2013-11-13T10:25:51 < dongs> or is this som weird shit
2013-11-13T10:26:20 < PaulFertser> -+----o-+-    <-- here it has 4 pins (2 up, 2 down), those pins near o are just NC

2013-11-13T10:39:01 < Guest83010> or should the LSE osc hardware be oscing without code interaction? in that case, it's dead meat
2013-11-13T10:39:29 < talsit1> well, the LSE is just not working
2013-11-13T10:39:39 < talsit1> so, i don't see how i'm going to keep an RTC

2013-11-13T11:40:48 < ABLomas> chinese sells > 20$ boards with similar touchscreen, even smaller - works OK, but no ethernet too :/
2013-11-13T11:40:54 < ABLomas> that's only one problem so far
2013-11-13T11:42:31 < zyp> «some arm development board»
2013-11-13T11:42:35 < zyp> that's very unspecific
2013-11-13T11:42:53 < talsit> ah... ethernet
2013-11-13T11:44:33 < zyp> ABLomas, there's a whole lot of difference between cortex-m and cortex-a, and you don't care about that?
2013-11-13T11:56:05 < ABLomas> probably no
2013-11-13T11:56:21 < ABLomas> CPU speed/features aren't really needed
2013-11-13T11:56:54 < ABLomas> my friend wants to do simple "visual monitoring" system
2013-11-13T11:57:44 < ABLomas> input data from ethernet (very low bitrate), simple parsing (text data, again, very low volume), display this on scren color (green/red), silence alarm by touching screen
2013-11-13T11:58:10 < ABLomas> that's all (at least now), so other features, CPU speed, etc isn't so important
2013-11-13T11:58:49 < zyp> it's not about speed, but the entire development environment
2013-11-13T11:59:04 < zyp> writing for a microcontroller is different from writing for linux
2013-11-13T11:59:34 < zyp> anyway, I believe there should be a bunch of stm32f107 boards around that would fit your requirements
2013-11-13T12:01:10 < zyp> http://www.ebay.com/itm/321103107516 <- like this
2013-11-13T12:01:41 < ABLomas> about IDE - no preference, friend will do everything from scratch, he was coding for PC, wants to try something new, so...
2013-11-13T12:03:23 < ABLomas> thanks for link, looks good, huge - but has everything needed
2013-11-13T12:03:29 < Guest83010> ebay has tons of good looking chinise board 40-100$
2013-11-13T12:04:21 < Guest83010> like zyp pasted ;)
2013-11-13T12:06:39 < ABLomas> yes, but "hey look, i used XXX and it's great, tried YYY and this sucks" can help choose right products ;-)

2013-11-13T13:07:36 < Steffan-> Should check the openocd developments more often
2013-11-13T13:08:16 < karlp> yeah, it's added to openocd, and I'd seen it in the notes, so was going to use it.

2013-11-13T13:30:09 < karlp> but it wasn't showing up in dmesg as inserting/removing a device
2013-11-13T13:30:21 < karlp> unplugged the hub and plugged it in again, and it's working ok now though

2013-11-13T13:30:39 < zyp> keep in mind that it probably only turns off vbus, so self-powered devices that doesn't turn off the d+ pullup on vbus loss will probably still show up as connected

2013-11-13T23:04:34 < Laurenceb_> why can't i say
2013-11-13T23:04:42 < Laurenceb_> uint8_t *a;
2013-11-13T23:04:51 < Laurenceb_> *a="test";
2013-11-13T23:04:54 < Laurenceb_> ?
2013-11-13T23:05:19 < Laurenceb_> oh of course
2013-11-13T23:05:21 < fbs> because a points to an int, you cant put a string in an int
2013-11-13T23:05:22 < Laurenceb_> ignore me
2013-11-13T23:05:25 < Laurenceb_> doh
2013-11-13T23:05:37 < gxti> you can, you just have to use a bigger hammer
2013-11-13T23:05:48 < Laurenceb_> the left had side is a pointer
2013-11-13T23:05:52 < Laurenceb_> *hand
2013-11-13T23:06:05 < Laurenceb_> *a=&("test");
2013-11-13T23:06:08 < Laurenceb_> would that work?
2013-11-13T23:06:13 < Laurenceb_> arg
2013-11-13T23:06:18 < gxti> let's try it this way
2013-11-13T23:06:18 < Laurenceb_> *a=*("test");
2013-11-13T23:06:21 < gxti> what do you THINK that would do?
2013-11-13T23:06:35 < fbs> a="test"
2013-11-13T23:06:48 < fbs> *a  is the thing pointed to by a
2013-11-13T23:06:55 < Laurenceb_> but will it know how many bytes to move?
2013-11-13T23:07:04 < fbs> move?
2013-11-13T23:07:06 < gxti> answer my question first
2013-11-13T23:07:14 < fbs> = is assignment, not a string copy
2013-11-13T23:07:31 < Laurenceb_> i dont know what it will do :P
2013-11-13T23:07:41 < Laurenceb_> i was wondering how to avoid strcpy
2013-11-13T23:07:49 < fbs> ...
2013-11-13T23:07:50 < gxti> *a is not a pointer, *a is an integer
2013-11-13T23:07:55 < gxti> a is a pointer
2013-11-13T23:08:01 < gxti> *a is the thing being pointed at
2013-11-13T23:08:12 < fbs> if you could do a string copy using '=' they wouldnt write a stringcopy function
2013-11-13T23:08:31 < Laurenceb_> fbs: but its from something declared at compile time
2013-11-13T23:08:41 < Laurenceb_> "test" is known
2013-11-13T23:08:49 < Laurenceb_> gxti: i see now
2013-11-13T23:08:55 < Laurenceb_> so only a single byte long
2013-11-13T23:08:55 < gxti> "test" is also a pointer, to a location in memory that happens to contain the word test and a null terminator.
2013-11-13T23:09:08 < Laurenceb_> yeah
2013-11-13T23:09:18 < Laurenceb_> so i can say
2013-11-13T23:09:25 < Laurenceb_> uint8_t a[]="test";

2013-11-13T23:09:55 < fbs> its a constant string
2013-11-13T23:10:00 < Laurenceb_> yeah
2013-11-13T23:10:03 < fbs> err not in that case
2013-11-13T23:10:54 < gxti> man why did i copy your i2c code if you don't know how pointers work :|
2013-11-13T23:11:01 < Laurenceb_> heh
2013-11-13T23:11:07 < gxti> at least i rewrote it so i know the only bugs are in the logic
2013-11-13T23:11:17 < Laurenceb_> im just confused by strings :P
2013-11-13T23:11:30 < fbs> a[] = "test";  a[1] = 'b'; is valid
2013-11-13T23:11:36 < Laurenceb_> sure
2013-11-13T23:12:00 < fbs> *a="test"; a[0] = 'b'; is invalid
2013-11-13T23:12:08 < Laurenceb_> yeah i get it
2013-11-13T23:12:30 < gxti> *a is a single character in a particular place (the place being defined by a)
2013-11-13T23:12:33 < Laurenceb_> thanks
2013-11-13T23:12:37 < gxti> *a = 'z' is valid
2013-11-13T23:13:21 < fbs> not if you define a as 'char * a = "test"'
2013-11-13T23:13:34 < Laurenceb_> why not?
2013-11-13T23:13:40 < Laurenceb_> wont it set first byte?
2013-11-13T23:13:47 < gxti> and where does that first byte live in RAM?
2013-11-13T23:13:53 < gxti> hint: trick question
2013-11-13T23:14:08 < Laurenceb_> well arm cortex has bytewise addressing...
2013-11-13T23:14:32 < Laurenceb_> oh nvm
2013-11-13T23:14:36 < Laurenceb_> '' versus ""
2013-11-13T23:14:41 < fbs> no
2013-11-13T23:14:53 < gxti> when you say "test" where do you think the letters t e s t go?
2013-11-13T23:15:08 < Laurenceb_> gxti: depends on the architecture?
2013-11-13T23:15:12 < fbs> no
2013-11-13T23:15:25 < gxti> not substiantially
2013-11-13T23:15:36 < Laurenceb_> so consecutive addresses?
2013-11-13T23:15:42 < fbs> RAM or ROM
2013-11-13T23:15:52 < Laurenceb_> depends if its const
2013-11-13T23:15:56 < fbs> no
2013-11-13T23:16:00 < gxti> "test" is always const.
2013-11-13T23:16:12 < gxti> it is a string constant, like 42 is an integer constant. you can't change 42.
2013-11-13T23:16:26 < Laurenceb_> sure, i was lazy reading the question
2013-11-13T23:17:01 < gxti> when you do "int x = 42", the 42 is in your program text and can't be mutated. same goes for "test".
2013-11-13T23:17:25 < gxti> now in the 42 case, once it's assigned to x you can change x because it's just a value. but for the string you're only storing a pointer (to a location you can't change)
2013-11-13T23:17:51 < gxti> you can change the value of the pointer but you can't change the bytes
2013-11-13T23:17:56 < Laurenceb_> ah
2013-11-13T23:18:14 < Laurenceb_> yeah that makes sense now
2013-11-13T23:18:19 < gxti> so you have to copy it to something that you CAN write
2013-11-13T23:18:54 < gxti> which is what strcpy does.
2013-11-13T23:22:43 < Steffan-> Laurenceb_, you should start to write and use arrays like this: int x[5]; 4[x] = 3; printf("%d", x[4]);
2013-11-13T23:23:15 < Laurenceb_>  4[x] = 3;
2013-11-13T23:23:17 < Laurenceb_> lulwut
2013-11-13T23:23:23 < fbs> small typo
2013-11-13T23:23:27 < Steffan-> nono :P

2013-11-14T01:41:02 <+dekar_> Whether or not you can write to string literals actually depends on the architecture/compiler. I remember casting away the const and manipulating a string literal on x86.
2013-11-14T01:43:09 < gxti> recently?
2013-11-14T01:44:07 < gxti> rodata is supposed to, and certainly can be, write-protected on any x86. but it's up to the libc whether it actually happens.
2013-11-14T01:44:49 < zippe> gxti: not libc, that'd be the dynamic linker
2013-11-14T01:45:03 < qyx_> hm, if you have different power and signal ground going in different cables between parts of the device
2013-11-14T01:45:06 < gxti> yes, you're right
2013-11-14T01:45:08 < qyx_> how do you eliminate ground loops?
2013-11-14T01:45:17 < qyx_> or what's the recommended way of handling this?
2013-11-14T01:45:38 < zippe> qyx: there should only be a single ground path from any point back to the power supply
2013-11-14T01:46:20 < zippe> qyx: if you need a shield ground, only connect it at one end of the cable
2013-11-14T01:46:28 < gxti> qyx_: you could use a big capacitor to couple ground from a signal wire into your pcb ground
2013-11-14T01:46:42 < gxti> you absoulutely need a return path for signals, but it only has to be AC
2013-11-14T01:46:43 < zippe> If you are concerned about common-mode noise, use balanced signals
2013-11-14T01:48:03 < qyx_> i just need to connect cpu board to power board with mosfet's using SPI

2013-11-14T01:48:42 < qyx_> however the cpu board ground is connected together with power ground in power supply
2013-11-14T01:49:33 < qyx_> so i can omit ground in SPI cable OR connect it directly OR connect using capacitor
2013-11-14T01:49:40 < zippe> I would just omit it
2013-11-14T01:49:47 < qyx_> none of these possibilities seem ok to me
2013-11-14T01:49:58 < gxti> what's the bandwidth of the signal?
2013-11-14T01:50:26 < qyx_> not too much, SPI IO expanders can go up to 10MHz
2013-11-14T01:51:11 < zippe> Unless the power ground is really dodgy, I wouldn't worry about it.
2013-11-14T01:51:18 < gxti> use a 100n cap if you're worried.
2013-11-14T01:52:58 < qyx_> ok, i will connect it at one end and leave unpopulated 0603 at the other
2013-11-14T01:57:31 <+dekar_> gxti, has been quite some time ago, I think it was Windows XP using GCC3, not sure though. Another weird thing I have tried is writing to the first string of argv, that actually changes the application name shown by "ps". :D
2013-11-14T01:57:55 < gxti> dekar_: yes, that's not rodata though
2013-11-14T01:58:11 < gxti> many daemons use it to show helpful status info
2013-11-14T01:58:31 < gxti> and if there's not enough room to put it all there (because you can't grow the buffer...) you use the space where environ was :p
2013-11-14T01:59:17 <+dekar_> I feel like that probably isn't defined behaviour :)
2013-11-14T02:00:36 < gxti> undefined but predictable and almost portable, close enough :P

2013-11-14T02:02:23 <+dekar_> I guess whatever my setup was back then (maybe cygwin?) resulted in the literal not ending up in rodata.
2013-11-14T02:02:40 <+dekar_> I just remember being confused that it worked.
2013-11-14T02:03:30 < gxti> it's not guaranteed by the language that it *won't* be writable
2013-11-14T02:03:38 < gxti> it's only type checking :-)

2013-11-14T09:38:35 < PaulFertser> laper: what linker script are you using and where did you get it from?
2013-11-14T09:43:36 < laper> PaulFertser: I use the default setting ( STM32F10x StdPeriph Lib v3.5 Project)
2013-11-14T09:45:41 < laper> I have installed the gnuarmeclipse software.
2013-11-14T09:49:04 < laper> and I choose the STM32F10x Medium Density( Flash size 128, RAM size 20). Some code work well in that, but not this one.

2013-11-14T09:57:56 < PaulFertser> laper: if you compile it as C then you shouldn't have anything in exidx section as it's dedicated to exception handling.
2013-11-14T09:58:28 < PaulFertser> laper: I do not like the ST's library, why do not you start with libopencm3 instead?
2013-11-14T09:58:46 < laper> The difference is this one include "stm32f10x.h", maybe this is the error comes from.
2013-11-14T10:01:18 < laper> PaulFertser: Thanks, if libopencm3 is better, I will turn to the libopencm3

2013-11-14T15:01:38 < zyp> who the fuck thinks writing drivers for on-chip peripherals that depends on drivers for off-chip stuff is a good idea?
2013-11-14T15:02:39 < zyp> this code has all the dependencies in the wrong order
2013-11-14T15:04:37 < Steffan-> but they have you now. ;)
2013-11-14T15:05:00 < karlp> it's all the same board right?
2013-11-14T15:05:01 < zyp> I don't want to fix it, I want to use it
2013-11-14T15:05:04 < karlp> it's called sensor fusion :)
2013-11-14T15:05:04 < zyp> karlp, no
2013-11-14T15:05:18 < karlp> ah well, ok then, that just sounds illy
2013-11-14T15:05:45 < karlp> Laurenceb: hardly fail, pretty fast way of getting a hardcopy
2013-11-14T15:05:53 < karlp> otherwise, setting up printers... joy
2013-11-14T15:06:17 < zyp> the driver in question is an uart driver, which depends on code for controlling a rs485 transceiver sitting on an extension board, this driver is in turn used by a modbus driver, which in turn is used by a driver for a modbus device
2013-11-14T15:06:55 < zyp> and I want to use the latter, through a different rs485 transceiver hardware
2013-11-14T15:07:02 < karlp> yeah, well, that's going to happen, unless you rewrite all the things that take a uart driver to also take a 485 driver
2013-11-14T15:07:06 < zyp> the uart is still the same
2013-11-14T15:07:24 < zyp> but the extension board with the transceiver is not there
2013-11-14T15:08:14 < karlp> the "driver" for the 485 transceiver isn't just a gpio toggling? that does nothing if the boards' not there?

2013-11-14T15:09:04 < karlp> you see ugliness in modbus driver code where they try and manage rs485 tx enable pins themselves because the uart code they use doesn't have support for it themselves,
2013-11-14T15:09:28 < zyp> in principle it should be
2013-11-14T15:09:43 < zyp> it's not a gpio, but a pin on a i2c io expander
2013-11-14T15:09:50 < zyp> (IIRC)
2013-11-14T15:10:58 < zyp> anyway, the problem is that I don't want to have to modify a core driver to add support for additional peripheral hardware

2013-11-14T15:28:39 < zyp> Steffan-, yeah, transceiver control has nothing to do with the uart
2013-11-14T15:28:58 < fbs> there are few interesting topic left, most is just the same old shit
2013-11-14T15:30:30 < Steffan-> btw zyp, don't upgrade to os x 10.9 when you dont have to /want to.. it has some annoying issue ( at least here )
2013-11-14T15:30:37 < zyp> oh?
2013-11-14T15:30:44 < trepidaciousMBR> It seems pretty hard to find the maximum current for GPIO on STM32F407, I assume it's on the datasheet somewhere :(
2013-11-14T15:30:55 < zyp> I kinda want to, but I haven't had time yet
2013-11-14T15:31:17 < trepidaciousMBR> Steffan-: I've been holding off myself, Lion completely destroyed my old macbook Air until I reinstalled from scratch
2013-11-14T15:31:32 < zyp> trepidaciousMBR, it's in the datasheet, and it's pretty easy to find

2013-11-14T15:37:26 < Steffan-> trepidaciousMBR, it did not destroy it, but it has some annoying (bugs) :(

2013-11-14T15:38:58 < zyp> Steffan-, care to elaborate?
2013-11-14T15:39:01 < Steffan-> The most annoying one is probably some dual screen issue and the fact that i have the habit to lock my screen when i walk away.
2013-11-14T15:39:18 < zyp> what dual screen issue?
2013-11-14T15:39:27 < Steffan-> when i unlock it some windows will get stick in the top-left of my main screen
2013-11-14T15:39:39 < Steffan-> *get stuck
2013-11-14T15:39:43 < zyp> the main reason I'm looking forward to 10.9 is the improved multi monitor support
2013-11-14T15:39:58 < Steffan-> They get very small, you can move them, but will move back when you release them..
2013-11-14T15:40:06 < zyp> heh
2013-11-14T15:40:46 < Steffan-> A "change" in screen order ( not sure what the correct english term is) fixes it :S
2013-11-14T15:41:19 < Steffan-> i had some more annoying issues, but now i can't remember them :(
2013-11-14T15:41:36 < zyp> can't be that annoying if you don't remember it :p
2013-11-14T15:42:21 < Steffan-> Yes there were annoying. Like a full screen app on screen 2, activating a window of the same app on screen 1, will make the dock disappear :D
2013-11-14T15:43:05 < Steffan-> So imho the wonderful dual-screen support isn't what it  could've been, yet.

2013-11-15T01:30:12 < zyp> that's kinda confusing, because «torsk» in norwegian means cod :p

2013-11-15T01:36:37 < karlp> Steffan-: with the hammer and the hardware store? :)
2013-11-15T01:36:45 < Steffan-> Yeah.
2013-11-15T01:37:27 < zyp> karlp, hmm, I still don't see any relations, which words does it relate to? :p
2013-11-15T01:38:13 < Laurenceb_> i like the µSD card holder
2013-11-15T01:38:30 < karlp> ah, no, just geeking out on a bad icelandic viking/western movie,
2013-11-15T01:38:47 < zyp> karlp, I'm just curious about the word :p
2013-11-15T01:38:49 < karlp> not many lines, one of them is "what is the news from norway"
2013-11-15T01:39:03 < karlp> no clue sorry,
2013-11-15T01:39:15 < zyp> because I can't see any related words in norwegian :p
2013-11-15T01:39:35 < karlp> well, we do pretend they're different languages
2013-11-15T01:39:42 < karlp> needs to be a few things separate :)
2013-11-15T01:39:58 < zyp> Laurenceb_, probably intended for phone stuff, where the rest of the card holder is made up of the phone chassis
2013-11-15T01:40:07 < Laurenceb_> yeah
2013-11-15T01:40:18 < Laurenceb_> i wonder if the card might slide out too easily
2013-11-15T01:42:11 < Laurenceb_> "A fast CPU and small amount of RAM means that a complete garbage collection takes under 4ms"
2013-11-15T01:42:23 < Laurenceb_> which is completely convenient on a microcontroller
2013-11-15T01:45:55 < zyp> Steffan-, isn't dutch and german also kinda similar but not completely understandable?
2013-11-15T01:46:26 < Steffan-> For an outsider, for me german is still pretty difficult.
2013-11-15T01:47:03 < Steffan-> but yeah,.. german and dutch are related.

2013-11-15T02:01:59 < qyx_> micro python on ks?
2013-11-15T02:02:32 < qyx_> there is a python-on-a-chip project available for a longer time
2013-11-15T02:03:05 < zyp> qyx_, it's even mentioned in the FAQ
2013-11-15T02:03:18 < gxti> as a full-time python developer i can think of a lot of better languages to put on a mcu
2013-11-15T02:03:23 < qyx_> hm, okay
2013-11-15T02:03:24 < zyp> rationale for not using that looks sane enough
2013-11-15T02:07:15 < zyp> gxti, dunno, I think I'd prefer using python on a stm32 over using arduino :p
2013-11-15T02:07:28 < Laurenceb_> i dont understand why youd run python on anything without an OS
2013-11-15T02:07:48 < karlp> synapse rf modules are even programmed in python as their "native" language
2013-11-15T02:07:57 < zyp> why does having an OS or not have anything to do with anything?
2013-11-15T02:08:17 < zyp> bunch of gsm modules also ship with python interpreters
2013-11-15T02:08:42 < Steffan-> I wonder when well see the stm32j on kickstarter :)
2013-11-15T02:08:43 < karlp> what's the difference between this an cython?
2013-11-15T02:09:07 < zyp> footprint, limitations, performance, etc
2013-11-15T02:09:18 < karlp> oh, you can drop .py files straight onto the mass storage device bootloader?
2013-11-15T02:09:21 < karlp> that's pretty nifty
2013-11-15T02:09:47 < gxti> cython translates to C, which is ok but you're working in a limited subset of python that can be expressed that way
2013-11-15T02:10:26 < zyp> I would imagine that this could be nice for making projects that are supposed to be user scriptable
2013-11-15T02:10:46 < gxti> i'm not hating on it, it just seems like misplaced effort
2013-11-15T02:11:10 < zyp> where would you place it?
2013-11-15T02:12:29 < qyx_> zyp: i've read the faq, it seems to be reasonable enough
2013-11-15T02:12:33 < gxti> someone here was compiling rust for stm32, that sounds interesting
2013-11-15T02:13:14 < gxti> a language with lower overhead than python that is safer than c and better checked than python
2013-11-15T02:13:41 < gxti> python won't smash your stack (unless you try really really hard) but it will let you typo method names and not find out for 3 years
2013-11-15T02:13:58 < zyp> true
2013-11-15T02:14:48 < gxti> python is strong when hardware resources are abundant and human resources are not -- fast to write code, easy to maintain it

2013-11-15T02:17:45 < Steffan-> printf :)
2013-11-15T02:19:02 < Steffan-> but you have to add -u _printf_float to the linker command if you use nano

2013-11-15T06:47:24 < englishman> nice pics rocketcom
2013-11-15T06:47:55 < talsit> which IMU is it?
2013-11-15T06:49:19 < talsit> in that first pic, what are the 2 chips around the stm32f407?
2013-11-15T06:50:10 < talsit> where are your sensors?
2013-11-15T06:50:43 < talsit> ah, i see the barometer now
2013-11-15T06:50:46 < talsit> the 2 below that?
2013-11-15T06:52:02 < englishman> how much was the rocket
2013-11-15T06:52:18 < englishman> only zeros
2013-11-15T06:54:06 < talsit> next to each connector, there's a chip, transceiver?

2013-11-15T07:01:07 < talsit> where do you get your F4's for $2?
2013-11-15T07:03:26 < talsit> they don't have any that are small, right? they're all bulky like that, right?
2013-11-15T07:04:22 < talsit> i have an interboard distance of 4.3mm, those are taller than that
2013-11-15T07:05:06 < talsit> i'm currently using this cheapo freescale one LGA, which is good enough, but i'm on the lookout for something better

2013-11-15T07:17:55 < talsit> i still have it in my "dubious chips" box

2013-11-15T16:16:39 < Robint91> Steffan-, it has a interrupt output

2013-11-15T16:24:12 < Steffan-> You tell me Robint91, you linked to them.
2013-11-15T16:24:25 < Robint91> Steffan-, these are dual interface ones
2013-11-15T16:24:27 < zyp> saw that earlier today, it's similar to M24LR, except it's using ISO14443A instead of ISO15369
2013-11-15T16:24:36 < Robint91> so RF+eeprom+I2C
2013-11-15T16:24:53 < Robint91> zyp, and it has a nice mechanic to do some dynamic stuff
2013-11-15T16:25:12 < Robint91> zyp, the NFC host can do signaling stuff (the INT pin)
2013-11-15T16:25:26 < Robint91> so that the mcu doesn't need to poll the i2c
2013-11-15T16:25:55 < gxti> i would think any NFC chip would have that, there are no NFC applications where at least one of the devices does not need to conserve power

2013-11-15T16:29:18 < Steffan-> You can talk to your printer, oven, washing machine, whatelse you want? For me it will take at least 5 years before i'll have a phone that does NFC
2013-11-15T16:29:19 < zyp> (in addition to being a normal reader and having p2p capability)
2013-11-15T16:29:43 < Robint91> zyp, it is active
2013-11-15T16:29:58 < zyp> Robint91, but not available from anywhere
2013-11-15T16:30:25 < gxti> if i were going to talk to my printer, oven, washing machine, or other things that are permanently plugged into the wall i'd use wifi
2013-11-15T16:30:41 < Steffan-> Robint91, st has many "active" chips that aren't available for at least a half a year...

2013-11-15T20:40:34 < Laurenceb> i think i found a bug in fatfs
2013-11-15T20:40:59 < Laurenceb> it doesnt like a µSD card thats almost full and badly fragmented
2013-11-15T20:42:06 < emeb> using the latest version?
2013-11-15T20:44:46 < emeb> and, does it barf on read or write?
2013-11-15T20:54:32 < jpa-> and what does it do?
2013-11-15T20:54:48 < jpa-> it is normal for FAT writing to slow down to halt when the disk is full and badly fragmented

2013-11-15T21:31:20 < ouah> hi
2013-11-15T21:32:56 < ouah> if I move the vector table, let's say from 0x0800000 to 0x08002000, and I do a soft reset: will the device restart from 0x0800000 or 0x08002000?
2013-11-15T21:33:29 < gxti> as i understand it the cpu core always resets, so VTOR gets put back to default
2013-11-15T21:34:16 < ouah> this makes sense to me
2013-11-15T21:34:30 < ouah> anybody disagrees?
2013-11-15T21:34:39 < gxti> i was thinking of something like that for a bootloader but ended up using a magic value in uninitialized RAM instead

2013-11-15T21:37:27 < gxti> the bootloader has to do relatively complex stuff so before it jumps to the application it should reset
2013-11-15T21:37:39 < gxti> i was having weird issues with the stack in the main application until i did that
2013-11-15T21:38:07 -!- Netsplit over, joins: fbs
2013-11-15T21:38:59 < ouah> gxti: resetting the stack pointer before jumping into app was not ok?
2013-11-15T21:39:34 < gxti> no, it was because when i jumped i was doing it from a thread in the rtos so it was using the process stack (PSP) not main stack (MSP). but the simplest way to switch to MSP was to just reset and jump before the RTOS.
2013-11-15T21:40:18 < gxti> plus RAM is never reset by hardware, so i could do a full system reset to make sure peripherals didn't remember anything from the bootloader either
2013-11-15T21:42:35 < DanielHolth> does your device have a small amount of backup memory that is made for those things?

2013-11-15T21:44:09 < gxti> it's not necessary, RAM is not reset by hardware. i just had to put one variable in a section that is not initialized by software on startup.
2013-11-15T21:45:39 < DanielHolth> nift
2013-11-15T21:50:13 < gxti> someday i should figure out the stack thing though, my knowledge of arm assembly and core functionality is pretty minimal

2013-11-16T01:09:09 < DLPeterson> can anybody recommend a JTAG debugger/flasher that they've had good experience with under Linux?  I've used the Olimex JTAG ARM USB Tiny-H and have been told the Black Magic probe is also quite good.
2013-11-16T01:10:04 < DLPeterson> I'm primarily targetting STM chips but it is possible that I would need to flash some other devices perhaps TI/Atmel/NXP, all Cortex-M3/M4 though.
2013-11-16T01:10:46 < DLPeterson> I need it to integrate with Eclipse pretty easily because I'm on a team of people who aren't going to use the command line or GDB directly
2013-11-16T01:11:05 < Laurenceb_> welllllll
2013-11-16T01:11:15 < Laurenceb_> i use a discovery board
2013-11-16T01:11:26 < Laurenceb_> but its not the most user friendly thing
2013-11-16T01:11:47 < DLPeterson> that isn't a JTAG debugger/flasher
2013-11-16T01:12:03 < DLPeterson> it has a built on usb - jtag, if i recall correctly
2013-11-16T01:12:14 < Laurenceb_> oh
2013-11-16T01:12:27 < Laurenceb_> when you say JTAG you mean J.T.A.G.   :P
2013-11-16T01:12:47 < Laurenceb_> discovery is SWD
2013-11-16T01:13:42 < DLPeterson> the STM Discovery board is a whole development board.  I already have a board and need to select JTAG/SWD debugger/flasher.
2013-11-16T01:13:52 < mtbg> most of usb jtag interfaces are just slightly modified applications of ft2232
2013-11-16T01:14:14 < DLPeterson> mtbg, which do you use in particular?
2013-11-16T01:14:48 < mtbg> I have a clone of amontec jtag key
2013-11-16T01:14:53 < mtbg> afair
2013-11-16T01:15:05 < DLPeterson> do you use that with openocd, or something else?
2013-11-16T01:15:15 < qyx_> i also used generic ftdi cable
2013-11-16T01:15:26 < mtbg> openocd
2013-11-16T01:15:36 < ds2> can generic ftdi cables do SWD with openocd?
2013-11-16T01:15:54 < DLPeterson> ds2, not sure, anybody else know?
2013-11-16T01:16:03 < DLPeterson> qyx_, which one?
2013-11-16T01:16:17 < qyx_> they should know swd but i never tried

2013-11-16T01:16:24 < ds2> nope, I been trying to find out
2013-11-16T01:16:28 < ds2> opencod can do swd
2013-11-16T01:16:35 < ds2> but will it work w/generic ftd
2013-11-16T01:16:47 -!- kuldeepdhaka [~kuldeepdh@117.254.217.1] has joined ##stm32
2013-11-16T01:17:01 < mtbg> mine is capable to do so by hardware design, it has even swd pins labelled on it, openocd docs says that one can use ftdi-based adapters for swd
2013-11-16T01:17:26 < mtbg> but I haven't tested this feature yet
2013-11-16T01:17:47 < qyx_> but the best you can do is probably to buy discovery board a use its stlink/stlinkv2
2013-11-16T01:17:52 < qyx_> *and
2013-11-16T01:17:59 < ds2> or just get a discovery for free
2013-11-16T01:18:03 < ds2> they seem to be given out like candy
2013-11-16T01:18:08 < mtbg> probably
2013-11-16T01:19:41 < DLPeterson> qyx_, that FTDI cable, you directly connect the appropriate pins of the cable to the jtag/swd pins of your MCU?
2013-11-16T01:19:52 < qyx_> yep
2013-11-16T01:20:19 < qyx_> it works ok for 3.3V targets
2013-11-16T01:20:35 < DLPeterson> qyx_, By "ok" do you mean you aren't super happy with it?
2013-11-16T01:20:53 < ds2> or use the ftdi ones with a level translator
2013-11-16T01:20:56 < DLPeterson> also, are you developing with it under Linux? Or windows/macosx?
2013-11-16T01:21:28 < qyx_> linux
2013-11-16T01:21:44 < DLPeterson> qyx_, thanks.
2013-11-16T01:21:57 < qyx_> not super happy, because openocd sometimes reconnects
2013-11-16T01:22:29 < qyx_> especially if you have longer cables
2013-11-16T01:22:53 < qyx_> probably tere should be some additional pullups/pulldowns
2013-11-16T01:23:01 < qyx_> i've never investigated that
2013-11-16T01:23:06 < DLPeterson> qyx_, ah. Yeah, I've sometimes had annoying OpenOCD issues. This one seems to cut OpenOCD out of the equation: http://sourceforge.net/apps/mediawiki/blackmagicdebug/index.php?title=Main_Page
2013-11-16T01:23:37 < DLPeterson> mtbg, do you have a link to the amontec jtag clone that you use?

2013-11-16T01:28:26 < DLPeterson> zyp, yeah, I remember you mentioned it to me in the past.  When you plug it in do you just fire up gdb and connect?
2013-11-16T01:28:33 < zyp> yes
2013-11-16T01:29:03 < mtbg> without openocd?
2013-11-16T01:29:19 < DLPeterson> mtbg, yeah, I believe so.
2013-11-16T01:29:25 < zyp> of course, bmp has it's own built in gdbserver
2013-11-16T01:29:37 < zyp> so gdb connects directly to the ACM serial port
2013-11-16T01:29:54 < mtbg> magic
2013-11-16T01:30:05 < mtbg> as the name states
2013-11-16T01:30:07 < DLPeterson> mtbg, this might be relevant: https://pixhawk.ethz.ch/px4/dev/jtag/gdb#gdb_init_for_black_magic
2013-11-16T01:30:58 < mtbg> that probably can be actually faster than that low level interfaces
2013-11-16T01:31:32 < DLPeterson> zyp, do you know of any other comparable products to bmp that remove OpenOCD from the picture?
2013-11-16T01:33:03 < zyp> I don't know of any other with the entire gdbserver built in, but there are other options than openocd for a gdbserver running on the host
2013-11-16T01:33:12 < zyp> versaloon, for instance

2013-11-16T01:36:09 < zyp> I'm mostly using SWD mode
2013-11-16T01:36:14 < DLPeterson> ok, good to know
2013-11-16T01:36:24 < DLPeterson> any downsides of SWD in your experience?
2013-11-16T01:36:42 < DLPeterson> also, do you target any chips besides ST ones?
2013-11-16T01:36:54 < zyp> no, it's fewer wires and slightly faster (on BMP) than jtag
2013-11-16T01:37:53 < zyp> in general, I believe you have boundary scan available on JTAG, which you lose with SWD, but I've never played with that
2013-11-16T01:38:34 < zyp> also, LPC4300 (the one with one M4 core and one M0 core in the same chip) only exposes both cores via JTAG, if you use SWD only the M4 shows up
2013-11-16T01:38:58 < zyp> I've been using it for LM4F and LPC4300 apart from stm32
2013-11-16T01:40:14 < zyp> the core is the same in either case, but the flash controllers are vendor specific, so the chip family you are using must be explicitly supported for flashing to work
2013-11-16T01:40:51 < mtbg> zyp: btw did you use high speed usb interface in that LPCs?
2013-11-16T01:40:57 < zyp> on the other hand, since the source is open, adding support for new families is rather easy, I've submitted a few patches for that
2013-11-16T01:41:12 < zyp> I did, but I never got around to playing with it
2013-11-16T01:41:50 < mtbg> with your own usb stack?
2013-11-16T01:42:12 < zyp> no, what I mean is that I hooked up the high speed interface on the board I made
2013-11-16T01:42:20 < zyp> but I never got around to porting my usb stack to it
2013-11-16T01:42:24 < zyp> so I've never tried it
2013-11-16T01:42:30 < mtbg> ok
2013-11-16T01:44:06 < zyp> I remember I got kinda annoyed over the insane gpio pin mapping, and then I found something more interesting to do, or something :p
2013-11-16T01:44:44 < zyp> I've tried high speed on stm32 however
2013-11-16T01:44:50 < zyp> with external phy
2013-11-16T01:45:36 < zyp> it kinda works, but requires more work to be proper
2013-11-16T01:45:56 < mtbg> I have it running too
2013-11-16T01:46:12 < mtbg> tried dma?
2013-11-16T01:46:16 < zyp> you don't know ahead of time whether you'll be connected to a full speed or a high speed host, and you're supposed to be able to talk to either
2013-11-16T01:46:43 < zyp> and each mode requires a different set of descriptors
2013-11-16T01:47:18 < zyp> so I need to put more work into that when I get to the point where I want proper highspeed support
2013-11-16T01:47:22 < mtbg> you can actually have just two descriptors for full speed if you don't want it
2013-11-16T01:47:27 < mtbg> a dummy device descriptor
2013-11-16T01:47:51 < zyp> huh?
2013-11-16T01:47:55 < zyp> that's not what I mean
2013-11-16T01:48:05 < mtbg> and a descriptor for capabilities which would be available if it was enumerated high speed
2013-11-16T01:48:10 < zyp> I'm talking about stuff like endpoint MPS
2013-11-16T01:48:11 < mtbg> (device qualifier?)
2013-11-16T01:48:31 < mtbg> yep, that matters too but your functions should already handle it properly
2013-11-16T01:48:46 < zyp> bulk endpoints have to have an MPS of 64 on FS and 512 on HS
2013-11-16T01:49:15 < mtbg> but anyway you can have just ep0 for fs if the device is meant to be always high speed
2013-11-16T01:49:25 < zyp> yeah, sure
2013-11-16T01:49:44 < zyp> if it's meant to always be high speed you could just refuse to enumerate in full speed :p
2013-11-16T01:49:50 < zyp> which is what I did
2013-11-16T01:50:52 < mtbg> LPC's usb hardware is somewhat better documented btw
2013-11-16T01:51:07 < mtbg> and the host mode in otg is just an EHCI compatible controller
2013-11-16T01:51:30 < zyp> anyway, that's on the list of stuff to address when I get time to rework the usb stack
2013-11-16T01:52:16 < mtbg> both LPC18xx/LPC43xx and stm32f4 do have dedicated dma for usb high speed
2013-11-16T01:52:47 < zyp> I know
2013-11-16T01:53:14 < mtbg> performance benchmark when copying dummy ram buffer to usb as fast as possible and with libusb on the host side gave me up to 33MB/s
2013-11-16T01:53:46 < mtbg> with 168MHz clock
2013-11-16T01:53:59 < zyp> that's not too impressive
2013-11-16T01:54:21 < mtbg> I don't know if it is host or device limited

2013-11-16T01:54:56 < mtbg> I think I'd need a hardware usb analyzer to examine that
2013-11-16T01:55:04 < zyp> I imagine the device would be fast enough to saturate the bus provided the host and software is keeping up
2013-11-16T01:55:07 < zyp> yeah
2013-11-16T01:55:53 < zyp> if the device is the bottleneck, you'll see a bunch of unanswered polls by the host in the trace
2013-11-16T01:57:15 < zyp> http://bin.jvnv.net/f/5pyzn.png <- like this, for instance
2013-11-16T01:58:33 < zyp> the device is fast enough to keep up with FS read, grabbing data from a memory buffer even without doublebuffering
2013-11-16T01:59:12 < zyp> i.e. writing the next packet to the FIFO doesn't happen before the previous one is sent, and still happens fast enough to not keeping the host waiting
2013-11-16T01:59:22 < zyp> without DMA or anything
2013-11-16T01:59:52 < zyp> but every eight packet causes a wait, to read a new 512B byte from the SD card
2013-11-16T01:59:54 < mtbg> full speed is pretty slow
2013-11-16T02:00:11 < mtbg> high is 40 times as fast
2013-11-16T02:00:56 < zyp> of course, I'm just saying that DMA doesn't really matter much when you only do FS :)

2013-11-16T19:22:47 < GargantuaSauce> looks like there is some prior art but yeah it uses undefined behaviour, lovely
2013-11-16T19:23:19 < GargantuaSauce> i guess i could roll my own userspace context switching if i was really into masochism
2013-11-16T19:24:33 < mtbg> you can write a proper context switching  in like 60 lines of code

2013-11-16T19:30:25 < mtbg> you need separate stacks for different threads
2013-11-16T19:30:41 < mtbg> which setjmp/longjmp doesn't provide
2013-11-16T19:32:15 < GargantuaSauce> right, duh
2013-11-16T19:43:25 < zyp> yeah, proper context switching is easy enough
2013-11-16T19:45:16 < jpa-> yeah, it is easier to do without setjmp/longjmp
2013-11-16T19:46:43 < jpa-> static void *stackptr asm("sp");   void switch_thread(void **old, void **new) { *old = stackptr; stackptr = *new; }   
2013-11-16T19:47:29 < jpa-> note: not proper, because it doesn't save registers ;)
2013-11-16T19:48:20 < GargantuaSauce> i'd probably halfass it by making that function use all the registers so the compiler automagically pushes them onto the stack
2013-11-16T19:49:09 < jpa-> lol, yeah.. asm("":::"r1" "r2" "r3" ... )   or something
2013-11-16T19:49:47 < jpa-> good starting point for the Halfassed OS (tm)
2013-11-16T19:49:52 < GargantuaSauce> :)
2013-11-16T19:57:29 < Tectu> what is the proper word for libraries like LwIP or CycloneTCP?   "TCP/IP library"?
2013-11-16T19:57:35 < Tectu> or "socket library"?
2013-11-16T19:58:04 < GargantuaSauce> IP stack library maybe?
2013-11-16T19:58:20 < GargantuaSauce> or just IP stack

2013-11-17T15:43:25 < jpa-> hmm.. STM32L1 discovery is NRND

2013-11-17T15:43:41 < jpa-> yes
2013-11-17T15:43:51 < fbs> anyone using the board in a design?
2013-11-17T15:43:52 < jpa-> not that it matters much, but seems like soon there will not be a cheap dev board for L1 series
2013-11-17T15:44:19 < zyp> isn't there several variants of that?
2013-11-17T15:45:13 < jpa-> i haven't seen

2013-11-17T15:45:49 < zyp> the former is NRND, the latter is active
2013-11-17T15:46:14 < fbs> nrnd = not recommended new design right?
2013-11-17T15:46:18 < zyp> yes

2013-11-17T18:28:20 < dongs> 100
2013-11-17T18:28:28 < BrainDamage> you get half of them

2013-11-17T18:29:55 < dongs> oh well, still LPC w/all the suckage that implies.
2013-11-17T18:30:25 < BrainDamage> more like phaillips
2013-11-17T18:31:05 < zyp> I should do something more with my boards
2013-11-17T18:31:09 < dongs> yeah.
2013-11-17T18:31:29 < dongs> you should also buy my f3 flyingthing.

2013-11-17T19:10:15 < mervaka> yeah, second version
2013-11-17T19:10:28 < mervaka> doing all the ethernet/PoE stuff this time

2013-11-17T19:10:44 < mervaka> and 4 channels out on TDM

2013-11-17T19:12:54 < mervaka> so PoE will supply me about 50v raw. will DC-DC that into +/-12v, +/-6v and then LDO the 6v into 5v/3v3
2013-11-17T19:13:16 < mervaka> might even be able to LDO the 50v into 48v phantom power too
2013-11-17T19:13:37 < mervaka> need to see what the lower allowable voltage for PoE is.

2013-11-18T08:16:28 < emeb_mac> only thing they have going for them is DIP.
2013-11-18T08:16:55 < emeb_mac> and the world is full of people who think that 0.1" through-hole is the only way to go.
2013-11-18T08:17:54 < PaulFertser> LPC has some DIP controllers too iirc.
2013-11-18T08:18:23 < Devilholk> I find that once people try SMT they realize how much nicer it is
2013-11-18T08:18:39 < dongs> dip sucks
2013-11-18T08:18:54 < PaulFertser> qfn is painful though
2013-11-18T08:18:57 < Devilholk> It is easier to replace a 100 pin SMT device than a 8 pin PTH
2013-11-18T08:19:05 < Devilholk> I don't mind qfn

2013-11-18T08:22:44 < PaulFertser> Devilholk: but how do you apply solder (or solder paste)?
2013-11-18T08:23:14 < PaulFertser> dongs: hobbists?
2013-11-18T08:23:16 < Devilholk> Either I apply it to the pads using a regular soldering iron or I use a syringe to dispence solder paste

2013-11-18T08:23:45 < Devilholk> If I do the former I apply extra flux ofcourse
2013-11-18T08:24:58 < PaulFertser> Devilholk: i found it hard to control the amount of solder when applying with an iron...
2013-11-18T08:25:43 < dongs> PaulFertser: no
2013-11-18T08:25:44 < Devilholk> PaulFertser: Well, one can slightly push it downwards and excess solder will flow out around it
2013-11-18T08:25:50 < Devilholk> It can be wicked up with solder wick
2013-11-18T08:26:09 < PaulFertser> Devilholk: heh, i'm afraid of bridges under the package in this case.
2013-11-18T08:26:13 < dongs> PaulFertser: there's a very distinct line between "hobby" and "wasting time"
2013-11-18T08:26:24 < dongs> doing QFN by hand for example goes in the second category
2013-11-18T08:26:36 < Devilholk> PaulFertser: Haven't happened to me yet though

2013-11-18T08:32:50 < emeb_mac> why not just use a stencil?
2013-11-18T08:33:25 < Devilholk> I would love to use a stencil
2013-11-18T08:33:43 < emeb_mac> you can get inexpensive stencils made mail-order
2013-11-18T08:33:51 < Devilholk> But then I need to order one since the laser cutter I have access to doesn't cut with high enough precision
2013-11-18T08:33:54 < emeb_mac> sufficient for hobby quantities.
2013-11-18T08:34:03 < emeb_mac> and fast
2013-11-18T08:34:08 < PaulFertser> For a hobby project one can just order some small boards from seeedstudios (and other such) for 1$ a board. 14$ gives you 10 boards plus delivery. And stencil would cost 70$ extra.
2013-11-18T08:34:18 < Devilholk> emeb_mac: I'm happy to hear suggestions for such places
2013-11-18T08:34:20 < dongs> and?
2013-11-18T08:34:33 < dongs> you can get cheapo kapton stencils but those are trash
2013-11-18T08:34:48 < Devilholk> Steel is the way to go, right?
2013-11-18T08:34:52 < emeb_mac> I got a cheapo kapton stencil from OSHstencils.com for ~$12
2013-11-18T08:35:03 < dongs> yeah, plastic is useless.
2013-11-18T08:35:10 < emeb_mac> worked great for the 3 boards I built from it.
2013-11-18T08:35:24 < Devilholk> 3 boards? I'd just go with the syringe
2013-11-18T08:35:36 < jpa-> PaulFertser: i usually tin the pads both on PCB and the device; just very slightly, and then apply enough flux; and i heat with just a normal iron, have to leave the pads longer for that though, like this    http://koti.kapsi.fi/jpa/stuff/pix/PICT0143.JPG
2013-11-18T08:35:57 < jpa-> though that one was easy because the QFN pads came up to the corner so one can see that it is properly soldered
2013-11-18T08:36:16 < emeb_mac> Devilholk: don't think I'd try a syringe on 0.5mm pads for a UDFN10
2013-11-18T08:36:18 < PaulFertser> jpa-: I see
2013-11-18T08:36:42 < Devilholk> emeb_mac: I admit it is a bit tricky, one has to smear it out =)
2013-11-18T08:36:56 < Devilholk> Because the needle has way to big hole
2013-11-18T08:37:04 < Devilholk> And a smaller hole would make it hard for the solder balls to pass

2013-11-18T08:51:51 < dongs> whats going on roughly, any idea?
2013-11-18T08:51:59 < dongs> im totally missing the point of why dspic neesd to PWM out
2013-11-18T08:52:24 < emeb_mac> the dsPIC is the M divider in the PLL
2013-11-18T08:53:12 < emeb_mac> lm1881 extracts sync. 555 stretches the pulse - the output goes into the phase detector. VCO output drives the dsPIC
2013-11-18T08:53:30 < emeb_mac> dsPIC divides the VCO by M and drives the other leg of the phase detector.

2013-11-18T08:54:54 < emeb_mac> overall the dsPIC clock is then locked to the video sync, so anything the dsPIC does will be stable on screen.

2013-11-18T08:55:27 < dongs> i guess ill just steal the buffer part
2013-11-18T08:57:52 < Devilholk> So the dsPIC displays something on screen
2013-11-18T08:57:53 < emeb_mac> don't quite understand what's going on with that HC125 though.
2013-11-18T08:58:23 < emeb_mac> yes - NTSC video in and dsPIC does an overlay.
2013-11-18T08:58:47 < Devilholk> Too bad nothing today uses composite video
2013-11-18T09:00:33 < emeb_mac> some cheap cameras do.

2013-11-18T14:01:07 < Thorn> I wonder why they're using a 2,000 euro IMU when $20 gyro boards are available on ebay
2013-11-18T14:01:44 < Thorn> (I wasn't able to get a quote for the sonar)
2013-11-18T14:02:00 < Steffanx> because $2000 = academic and ebay is hobby bobby :)
2013-11-18T14:04:50 < Thorn> apparently the only custom hardware is a few analog sensor input boards with CAN, everything else is OTS
2013-11-18T14:08:49 < Steffanx> "Code is stored in private git repository on bitbucket.org." .. is that relevant? :)

2013-11-18T14:38:18 < dongs> i noticed it was doing some dodgy writes to undocumented shit

2013-11-18T14:38:44 < karlp> awesome. I wonder if it's important.
2013-11-18T14:39:00 < karlp> it also does it via a writemem32, instead of the write_debug_reg stlink command.
2013-11-18T14:41:01 < karlp> hrmm, no, my bad, was decoding these commands badly.

2013-11-18T20:43:23 < jpa-> rlc: Tectu has made a board with SRAM IIRC
2013-11-18T20:44:05 < rlc> Cool
2013-11-18T20:44:29 < rlc> One thing I would like to know is if I need to do control impedance design
2013-11-18T20:44:44 < rlc> My SRAM is 10 ns
2013-11-18T20:52:55 < zyp> probably not, you're still only talking 100 MHz

2013-11-18T20:54:08 < jpa-> rlc: have a ground plane and keep the traces sane and you should be fine
2013-11-18T20:54:45 < gxti> a 100mhz square wave has harmonics well above that, of course
2013-11-18T20:57:29 < rlc> jpa: what do you mean by keeping the traces sane?
2013-11-18T20:57:54 < jpa-> rlc: well reasonably well together, i.e. don't go running one address line around the board or anything like that
2013-11-18T20:59:25 < rlc> ok
2013-11-18T20:59:59 < rlc> Can I mix the address lines on an SRAM?
2013-11-18T21:00:10 < jpa-> yeah, you can sort them any way you like
2013-11-18T21:00:31 < jpa-> also data lines, though if you have byte enables and 16-bit bus you'll have to keep D0-D7 and D8-D15 separate
2013-11-18T21:00:33 < rlc> That would sure make routing easier
2013-11-18T21:01:49 < rlc> jpa: can the "byte enables" be disabled?  I'm using a 16 bits data bus
2013-11-18T21:03:47 < zyp> huh?
2013-11-18T21:03:56 < zyp> that's why you need them :p
2013-11-18T21:04:38 < zyp> if you are doing an 8-bit write, you need to have the byte enables so that the other 8 bits in the 16-bit word doesn't get modified
2013-11-18T21:05:05 < jpa-> rlc: hmm, no, doesn't seem like that
2013-11-18T21:05:15 < jpa-> zyp: well theoretically it could do read-modify-write
2013-11-18T21:06:09 < rlc> Ah, so byte enable is for shared address/data bus?
2013-11-18T21:06:13 < jpa-> no
2013-11-18T21:06:14 < zyp> no
2013-11-18T21:06:19 < jpa-> it is for 16-bit data bus
2013-11-18T21:06:41 < zyp> it's for doing writes smaller than the bus width
2013-11-18T21:06:43 < jpa-> if you want to write single bytes to memory with 16-bit data bus, you need byte enable
2013-11-18T21:07:11 < gxti> and you do, because you will when you least realize it and your head  will explode trying to debug it
2013-11-18T21:07:24 < rlc> ah!
2013-11-18T21:08:00 < rlc> That's what UB pin and LB pin for I guess
2013-11-18T21:08:26 < jpa-> indeed
2013-11-18T21:08:26 < zyp> yep
2013-11-18T21:10:52 < jpa-> check that the polarity is right also
2013-11-18T21:11:13 < rlc> Of which pins?

2013-11-19T00:32:28 < Tectu> did anyone of you ever implement a simple cooperative multitasking?

2013-11-19T00:33:07 < qyx_> ?
2013-11-19T00:33:37 < Tectu> yes
2013-11-19T00:33:44 < Tectu> but with a nice addTask() interface etc.
2013-11-19T00:34:50 < qyx_> so add list with function pointers and call them one-by-one
2013-11-19T00:35:04 < Tectu> yep

2013-11-19T00:56:12 < zyp> Tectu, my multitasking is cooperative
2013-11-19T00:56:44 < Tectu> zyp, is it a simple implementation?
2013-11-19T00:56:48 < zyp> real simple stuff, just round robin task switching, no checking whether threads are ready to run or not
2013-11-19T00:56:58 < Tectu> is it available?
2013-11-19T00:57:08 < zyp> of course
2013-11-19T00:57:26 < zyp> http://cgit.jvnv.net/laks/tree/os/thread.h http://cgit.jvnv.net/laks/tree/os/thread.cpp http://cgit.jvnv.net/laks/tree/interrupt/fault.cpp

2013-11-19T00:57:53 < zyp> so, 90 lines or so in total?
2013-11-19T00:58:02 < zyp> doesn't get simpler :p
2013-11-19T00:58:56 < Tectu> well, I need some more portable solution :P
2013-11-19T00:59:20 < zyp> portable to what?
2013-11-19T00:59:45 < Tectu> different architectures
2013-11-19T01:00:04 < zyp> umm
2013-11-19T01:00:16 < Tectu> hmm, the adventage by using longjmp I see is that you can early-release a thread when it does sleep.
2013-11-19T01:00:24 < Tectu> in your case it would just be blocking, no?
2013-11-19T01:00:28 < Tectu> until it returns
2013-11-19T01:00:34 < zyp> of course not
2013-11-19T01:00:48 < zyp> http://cgit.jvnv.net/laks/tree/os/time.h
2013-11-19T01:04:56 < zyp> anyway, you need three things for multithreading; initial stack setup, context switch and scheduling
2013-11-19T01:05:36 < zyp> both stack setup and context switch is architecture dependent and therefore inherently unportable, so you're left with scheduling
2013-11-19T01:05:51 < zyp> Thread::active_thread = Thread::active_thread->next; <- there's my scheduler, it's portable :D
2013-11-19T01:07:23 < zyp> http://cgit.jvnv.net/laks/tree/os/thread.h?h=scheduler_improvements <- oh, I also have this, it might be interesting if you want something a bit better :p

2013-11-19T06:00:13 < emeb_mac> no doubt
2013-11-19T06:00:37  * emeb_mac remembers the hi-G testing lab at the gov't contract outfit he used to work at.

2013-11-19T06:04:59 < englishman> maybe there is some sort of startup routine that expects values in a "sane" range before starting the output.

2013-11-19T06:07:33 < englishman> interesting

2013-11-19T06:16:02 < Thorn> he did it for fun, not to save costs
2013-11-19T06:19:46 < dongs> < R2COM> but... turns out that not quite normal in this specific scenario (turned OFF, immediate launch 0-10 seconds 0-18g,
2013-11-19T06:19:50 < dongs>                then right away turn ON)
2013-11-19T06:20:01 < dongs> i bet they are running self-test at power up, and the mems mass is affected by acceleration
2013-11-19T06:20:04 < dongs> thats why shit dont work
2013-11-19T06:20:07 < dongs> and it fails
2013-11-19T06:20:39 < dongs> if there's some selftest result registers you can probly see the fail reason

2013-11-19T19:30:58 < karlp> stupid writemem32 function, that takes a count in bytes, not in 32bit words
2013-11-19T19:31:17 < jpa-_> i always hate the functions that do the opposite
2013-11-19T19:31:25 < jpa-_> i guess i can blame you for those from now on :)
2013-11-19T19:31:52 < karlp> well, I don't know exactly where the name "writemem32" came from anyway, it's in the texane/stlink/oocd/ headers,
2013-11-19T19:32:21 < jpa-_> will you produce a nice python library for interfacing the stlink?
2013-11-19T19:32:22 < karlp> still doing something wrong with disconnecting cleanly and reconnecting, but that's minor
2013-11-19T19:32:46 < karlp> first and foremost is using this new fancy swo output to actually fix the bug I'm meant to be fixing .)
2013-11-19T19:33:00 < karlp> but yeah, this code I've hacked out would fit quite well into pyOCD,

2013-11-19T19:34:11 < jpa-_> it's always a bad thing if you have to start debugging by building new debugging tools :D
2013-11-19T19:36:26 < karlp> well, oocd got some swo support added, but it's.... not really working very well, but I oculd see that it _should_ work.
2013-11-19T19:37:12 < karlp> and I'd poked a little bit of pyusb before, and all the basic commands are well enough known in texane/oocd/etal that it wasn't _toooo_ hard.
2013-11-19T19:38:02 < trepidaciousMBR> Has anyone run into an approximately 1-byte delay when trying to send bytes over USART after changing USART settings (speed, etc.)?
2013-11-19T19:38:18 < jpa-_> btw, what kind of traces can one get reasonably with stlinkv2? i figure it cannot possibly be fast enough to get full log of instructions executed?
2013-11-19T19:38:33 < karlp> 2 Mhz max
2013-11-19T19:38:50 < karlp> so you can get a _lot_ but no, not full speed of all instructions
2013-11-19T19:39:06 < jpa-_> well my processor runs at 512kHz anyway ;)
2013-11-19T19:39:19 < karlp> but that should still be plenty of dumping capability, and a lot less intrusive than semihosting/uarts
2013-11-19T19:40:02 < karlp> I've only got a basic two channel printf working at the moment, but just having separate channels is nice too.
2013-11-19T19:40:10 < bsdfox> trepidaciousMBR, yes I was having that issue with my 1-wire master code.. 1 sec
2013-11-19T19:40:24 < trepidaciousMBR> bsdfox: Ah, this is also on 1-wire master code, probably yours :)
2013-11-19T19:40:29 < karlp> I had a niggle or two with the pointer I was using to write 8bti data to a 32bit address, as people have had before too,
2013-11-19T19:40:32 < jpa-_> karlp: 2MHz = 2Mbit/s, i assume?
2013-11-19T19:41:06 < karlp> something like that,
2013-11-19T19:41:15 < trepidaciousMBR> bsdfox: This one? http://forum.chibios.org/phpbb/viewtopic.php?f=8&t=713
2013-11-19T19:41:32 < karlp> less in practice I presume, but I can't be arsed counting out what it would be finally.
2013-11-19T19:41:48 < karlp> seems like should be enough for at least 1Mbit though :)
2013-11-19T19:41:49 < jpa-_> yeah, but something like that
2013-11-19T19:41:59 < bsdfox> trepidaciousMBR, nope.. I haven't posted mine anywhere (it works but there's no crc checking and the code needs cleanup)
2013-11-19T19:42:30 < trepidaciousMBR> bsdfox: Ah ok, that one I linked is pretty nice, has crc and rom search, I'm just improving it a bit on the timing
2013-11-19T19:42:42 < bsdfox> trepidaciousMBR, I think this fixed it for me- 	while ((USART2->ISR & USART_ISR_TC) == 0); instead of USART_ISR_TXE
2013-11-19T19:46:43 < trepidaciousMBR> bsdfox: Ah cool, I'll see if that can be done in ChibiOS. TBH I forgot I was in stm32 not chibios channel, doh :(
2013-11-19T19:47:11 < trepidaciousMBR> bsdfox: OTOH the crc code there might still be useful to you :)

2013-11-19T19:58:17 < bsdfox> then I started watching other flags to see if I could eliminate the delays and I was able to
2013-11-19T19:58:37 < bsdfox> I don't know why TXE seems to be set earlier than TC though
2013-11-19T19:58:54 < trepidaciousMBR> bsdfox: Ah great, I'll maybe mention it on the ChibiOS forum to see whether it's a possible fix to the driver. For now I think the delay is ok, since 1-wire is so slow anyway ;)
2013-11-19T19:59:22 < bsdfox> trepidaciousMBR, yeah.. and I'm using blocking code so it's really no different :P

2013-11-19T20:07:26 < gxti> also probably TXE is level-triggered and TC is edge-triggered so that might complicate things

2013-11-19T20:12:38 < gxti> buspirate hardware is pretty boring
2013-11-19T20:12:53 < gxti> the only way to 'stand out' would be to do a good job on the software
2013-11-19T20:13:36 < TitanMKD> in fact buspirate is just base idea
2013-11-19T20:13:48 < TitanMKD> with shell over serial usb
2013-11-19T20:14:26 < TitanMKD> but of course special features like NFC shield with special features like proxmark3 ...
2013-11-19T20:15:05 < TitanMKD> and also main board have microsdcard to be also a logger or even to launch script ...
2013-11-19T20:15:12 < gxti> sounds pretty incoherent to me
2013-11-19T20:15:20 < TitanMKD> with an extremely small size 60*37mm
2013-11-19T20:15:35 < TitanMKD> gxti: it is just a multipurpose board
2013-11-19T20:15:56 < TitanMKD> for hackers, developers or even final users depending on extension board used with full firmware
2013-11-19T20:16:00 < TitanMKD> not just an API to use
2013-11-19T20:17:09 < TitanMKD> it is why it is not really comparable to BusPirate
2013-11-19T20:17:33 < TitanMKD> of course I use a STM32F4 @168Mhz behind ;)
2013-11-19T20:18:19 < gxti> well i've already got a f4 discovery that i hardly use, why should i consider your thing?

2013-11-19T20:19:35 < gxti> if firmware is the product then wouldn't it be smarter to start with f4discovery so you don't have to worry about manufacturing?
2013-11-19T20:20:15 < TitanMKD> discovery is too big
2013-11-19T20:20:21 < TitanMKD> mine is 60x37mm
2013-11-19T20:20:29 < TitanMKD> it is a real embedded and autonomous product
2013-11-19T20:20:42 < TitanMKD> widt dual USB too and full breakout of all pins
2013-11-19T20:21:12 < TitanMKD> of course f4discovery is very nice especially the price which is unbeatable ;)
2013-11-19T20:21:47 < TitanMKD> but it is not ultra portable and not autonomous ... and big and lot of IO are already dedicated to some stuff like accelerometer ...
2013-11-19T20:22:43 < GargantuaSauce> http://xn--d-bga.su/shitcopter.jpg perfectly portable
2013-11-19T20:23:11 < TitanMKD> I just think there is tons of embedded board with a huge fragmentation i just hope this project will do tons of functionality found on different board
2013-11-19T20:23:43 < TitanMKD> GargantuaSauce: yes good for a demo but the size is hmm huge ;)
2013-11-19T20:23:58 < gxti> 60x37 is not tiny
2013-11-19T20:24:08 < gxti> smaller yes, but i don't see it as a big differentiator
2013-11-19T20:24:12 < GargantuaSauce> i'll gladly accept a free f4 board
2013-11-19T20:24:17 < TitanMKD> gxti: I think it is good size for good extension/shields ;)
2013-11-19T20:24:18 < gxti> really the only valid criticism is the IO usage
2013-11-19T20:24:20 < zyp> hmm
2013-11-19T20:24:36 < gxti> but if you want to address 'fragmentation' the solution isn't to make another board
2013-11-19T20:24:48 < zyp> TitanMKD, you were doing some stuff with some TI NFC chip once, right?
2013-11-19T20:24:54 < TitanMKD> zyp: yes
2013-11-19T20:25:03 < TitanMKD> zyp: and i plan such extension board ;)
2013-11-19T20:25:08 < zyp> how did that go?
2013-11-19T20:25:13 < TitanMKD> zyp: a portable NFC hack shield
2013-11-19T20:25:32 < TitanMKD> with realtime sniffer autonomous ;)
2013-11-19T20:25:39 < TitanMKD> using microsdcard ...
2013-11-19T20:26:03 < TitanMKD> the code is ready since years on stm32f4 discovery
2013-11-19T20:26:07 < zyp> http://bin.jvnv.net/f/AV2YQ.JPG <- I were playing with this a couple of months ago, I couldn't get it to pick up mifare cards
2013-11-19T20:26:15 < gxti> oh, so you *did* start by writing firmware. that's good.
2013-11-19T20:26:22 < zyp> works fine with vicinity cards though
2013-11-19T20:26:25 < TitanMKD> now it will don't need any wire just plug the 2 board together and power up ;)
2013-11-19T20:26:48 < zyp> so I'm just wondering, which cards did you get yours working with?
2013-11-19T20:26:54 < TitanMKD> zyp: Mifare ;)
2013-11-19T20:26:55 < gxti> that reminds me, i should start on my isolated BMP
2013-11-19T20:27:06 < TitanMKD> zyp: sniffer for Mifare in fact
2013-11-19T20:27:13 < TitanMKD> zyp: with realtime decrypt planned
2013-11-19T20:28:01 < zyp> ok, so why doesn't my chip pick up mifare cards?
2013-11-19T20:28:04 < TitanMKD> zyp: anyway i use a special mode in trf7970a with special optimized code to filter and decode symbol in realtime (less than 1us)
2013-11-19T20:28:23 < zyp> right, so you're not using the internal stuff at all, just using it as a tuner?
2013-11-19T20:28:34 < zyp> that would explain it
2013-11-19T20:28:40 < TitanMKD> I use internal and AGC ;)
2013-11-19T20:28:49 < TitanMKD> it is a mix of feature i use for sniffer
2013-11-19T20:29:06 < TitanMKD> else for simple UID reader it is ultra easy for Mifare or other card
2013-11-19T20:29:21 < zyp> I'm not interested in sniffing, I'm just interested in something that works
2013-11-19T20:29:23 < TitanMKD> to read data it is harder as you need to implement crypto
2013-11-19T20:29:36 < TitanMKD> and you need to switch to special mode
2013-11-19T20:29:48 < TitanMKD> to avoid for example automatic CRC ...
2013-11-19T20:30:13 < TitanMKD> Mifare are not compliant with 14443A in fact even if they are based on it
2013-11-19T20:30:20 < zyp> I know
2013-11-19T20:30:47 < TitanMKD> anyway TRF79760 suxx
2013-11-19T20:30:50 < TitanMKD> I use TRF7970A
2013-11-19T20:30:56 < TitanMKD> support more modes ;)
2013-11-19T20:31:01 < TitanMKD> better power
2013-11-19T20:31:26 < zyp> sure, but I didn't need p2p mode
2013-11-19T20:31:37 < zyp> but I can agree that it sucks
2013-11-19T20:31:43 < TitanMKD> i can read UID or data on credit card Mifare board at up to 10cm ;)
2013-11-19T20:31:56 < zyp> I'm just not convinced that trf7970a sucks less
2013-11-19T20:32:34 < gxti> sucks differently!
2013-11-19T20:32:44 < TitanMKD> if you are interested i will send you a full kit with my NFC board TRF7970A with the firmware
2013-11-19T20:33:16 < TitanMKD> I have already designed 2 version of it and send them to tons of students/university ...

2013-11-19T20:44:46 < TitanMKD> zyp: which problem exactly ?
2013-11-19T20:45:19 < TitanMKD> I have made a simple tutorial it should work for trf7960 too
2013-11-19T20:45:24 < zyp> I never got a response from any mifare cards
2013-11-19T20:45:26 < TitanMKD> too read UID on Mifare board
2013-11-19T20:45:50 < TitanMKD> I also implemented multi card on firmware
2013-11-19T20:46:21 < TitanMKD> you can read this

2013-11-19T20:46:55 < zyp> I tried both classic, ultralight and desfire, but neither would respond to either REQA or ATQA
2013-11-19T20:47:13 < TitanMKD> maybe you have a hw issue too
2013-11-19T20:47:33 < TitanMKD> anyway I only know trf7970a even if 7960 is same on some part
2013-11-19T20:47:41 < zyp> works fine for ISO15693 cards though

2013-11-19T21:00:18 < TitanMKD> 02 instead of 88
2013-11-19T21:00:27 < TitanMKD> but maybe it is not true for trf7960
2013-11-19T21:00:43 < TitanMKD> oups ;)
2013-11-19T21:00:51 < TitanMKD> i was reading the conf for Vicinity ;)

2013-11-19T21:01:30 < TitanMKD> you should maybe read back register written to check they are configured like expected
2013-11-19T21:01:49 < TitanMKD> also
2013-11-19T21:01:51 < zyp> I tried, they are
2013-11-19T21:01:52 < TitanMKD> 0x00 0x21
2013-11-19T21:02:01 < TitanMKD> i use 0x00 0x20
2013-11-19T21:02:05 < zyp> I tried both
2013-11-19T21:02:19 < TitanMKD> then after you need tons of commands
2013-11-19T21:02:44 < TitanMKD> like again
2013-11-19T21:02:49 < TitanMKD> 0x01 0x88
2013-11-19T21:02:55 < zyp> of course, but I don't need the second command if the first fails :)
2013-11-19T21:02:56 < TitanMKD> and
2013-11-19T21:02:56 < TitanMKD> 0x8F 0x90 0x3D 0x00 0x0F 0x26
2013-11-19T21:05:17 < TitanMKD> you should also check SPI MOSI/MISO with a logic analyzer to be sure you have no noise or wrong data
2013-11-19T21:05:23 < zyp> http://paste.jvnv.net/view/7sasw <- this is what I have for reading vicinity UID, this works
2013-11-19T21:05:26 < zyp> I did
2013-11-19T21:05:30 < TitanMKD> and of course check clock
2013-11-19T21:05:39 < zyp> also done
2013-11-19T21:05:41 < zyp> oh, yeah
2013-11-19T21:05:45 < TitanMKD> and all is good ?
2013-11-19T21:06:04 < zyp> these TI chipsets are fucking stupid, having a different polarity between reads and writes :p
2013-11-19T21:06:22 < TitanMKD> ha for spi ;)
2013-11-19T21:06:28 < TitanMKD> this bug is not present on TRF7970A
2013-11-19T21:07:37 < TitanMKD> also which mode are you using ?
2013-11-19T21:07:43 < TitanMKD> SPI with CS or PArallel ?
2013-11-19T21:07:48 < zyp> SPI with CS
2013-11-19T21:07:53 < TitanMKD> ok
2013-11-19T21:08:34 < TitanMKD> try to add
2013-11-19T21:08:35 < TitanMKD> 0x01 0x88
2013-11-19T21:08:42 < TitanMKD> again before to send 0x8F ....
2013-11-19T21:08:46 < TitanMKD> for REQA
2013-11-19T21:09:03 < zyp> I believe I did
2013-11-19T21:09:16 < TitanMKD> have you checked the SysClk ?
2013-11-19T21:09:30 < TitanMKD> or even connect an scope probe directly on antenna to check the power ?
2013-11-19T21:10:00 < zyp> this is a TI demoboard, I imagine they know what they are doing when they designed it :p
2013-11-19T21:10:22 < zyp> and it works with vicinity cards
2013-11-19T21:10:28 < TitanMKD> but maybe it have some solder bridge or something wrong ...
2013-11-19T21:10:55 < qyx_> don't they have some demo code?
2013-11-19T21:11:03 < TitanMKD> I had build lot of trf7970a and the QFN is ch**** sometime pads was not soldered correctly and Vicinity was working but Mifare was not ...
2013-11-19T21:11:28 < TitanMKD> with tons of random stuff
2013-11-19T21:12:35 < TitanMKD> also my firmware even support TI GUI TRF7970A very good to test each register by hand with a confortable GUI
2013-11-19T21:13:05 < TitanMKD> even if their PC sw is full of bug and hang ... ;)
2013-11-19T21:13:27 < TitanMKD> especially the scan mode with all protocol cycled ;)
2013-11-19T21:14:49 < zyp> anyway, I gave up and got the m24lr-discovery kit for the cr95hf based reader board, and that worked on the first try
2013-11-19T21:14:57 < zyp> and has a much nicer interface

2013-11-19T21:15:23 < TitanMKD> trf are the best chipset ever ;)
2013-11-19T21:15:31 < TitanMKD> not limited in any area with raw mode ;)
2013-11-19T21:15:39 < TitanMKD> you can just do anything on 13.56MHz
2013-11-19T21:16:13 < zyp> except raw mode reduces it to a dumb frontend, and I'm not interested in having to do SDR NFC to get it working
2013-11-19T21:16:17 < TitanMKD> without needing an FPGA ;) thanks to M4 special instruction and raw mode
2013-11-19T21:16:49 < TitanMKD> SDR NFC is really interesting ;)
2013-11-19T21:17:03 < TitanMKD> especially to test some badly implemented stuff like Phone
2013-11-19T21:17:17 < TitanMKD> I crashed my Android Nexus S with custom NFC stuff ;)
2013-11-19T21:18:10 < TitanMKD> there is tons of things to discover and NFC is more and more used everyday
2013-11-19T21:18:12 < zyp> I'm not interested in testing badly implemented stuff, I'm interested in a chip that's able to read tags like it's supposed to
2013-11-19T21:18:20 < zyp> because that's what I'm gonna use it for
2013-11-19T21:18:31 < TitanMKD> of course it is the primary usage ;)
2013-11-19T21:19:03 < TitanMKD> 2nd option is to emulate boards ;)
2013-11-19T21:19:08 < zyp> the nice thing about cr95hf is that it's command driven rather than register driven
2013-11-19T21:19:10 < TitanMKD> to avoid having 50x NFC cards
2013-11-19T21:19:47 < TitanMKD> yes i imagine it is probably less low level as trf7960...
2013-11-19T21:19:47 < zyp> oh, strfnfca which is the next generation after cr95hf has card emulation mode too
2013-11-19T21:19:53 < TitanMKD> like NXP PN532
2013-11-19T21:19:56 < TitanMKD> very high level
2013-11-19T21:19:58 < zyp> probably
2013-11-19T21:20:08 < TitanMKD> I implemented a full firmware on PN532 + PIC32 ;)
2013-11-19T21:20:15 < zyp> PN532 doesn't do vicinity cards which is a requirement for my application
2013-11-19T21:20:15 < TitanMKD> the fastest reader ever
2013-11-19T21:20:34 < TitanMKD> yes anyway PN532 do only Mifare ;)
2013-11-19T21:21:04 < TitanMKD> I have also tested Vicinity Read/Write Sector it work fine on TRF
2013-11-19T21:21:21 < zyp> yes, vicinity works fine
2013-11-19T21:21:24 < TitanMKD> I have a high level API for that
2013-11-19T21:21:40 < zyp> but 14443a support is pretty useless :p
2013-11-19T21:22:35 < TitanMKD> I will make demo of peer to peer mode ;)

2013-11-19T21:24:33 < TitanMKD> the most funny to show how tons of NFC are badly managed is sniff and replay mode ;)

2013-11-19T21:26:18 < zyp> well, sure
2013-11-19T21:26:27 < TitanMKD> I also doubt it support raw mode
2013-11-19T21:26:46 < zyp> a bunch of nfc applications is essentially replacing barcodes
2013-11-19T21:26:52 < TitanMKD> yep
2013-11-19T21:26:59 < zyp> barcodes aren't really secure either
2013-11-19T21:27:12 < TitanMKD> yes but they say NFC is secure ;)
2013-11-19T21:27:12 < zyp> which is not a problem for the kind of stuff barcodes is used for
2013-11-19T21:27:33 < TitanMKD> but for access it is a bad idea to use only ID
2013-11-19T21:27:38 < zyp> of course
2013-11-19T21:28:18 < zyp> about as stupid as using barcodes as ID
2013-11-19T21:28:24 < TitanMKD> yes ;)
2013-11-19T21:29:00 < zyp> that said, the canteen at work is using barcodes as ID for lunch accounts
2013-11-19T21:29:05 < zyp> seems to work fine enough
2013-11-19T21:29:06 < TitanMKD> ha no i was wrong CR95HF support 14443 Type B too
2013-11-19T21:29:38 < zyp> CR95HF supports pretty much everything in reader mode, but lacks P2P mode
2013-11-19T21:29:38 < TitanMKD> anyway they don't care of security for people ;)
2013-11-19T21:29:58 < TitanMKD> as the problem is someone can steal ID of a user and use it
2013-11-19T21:30:06 < zyp> STRFNFCA is pin compatible with CR95HF and adds P2P mode and tag emulation, but isn't available yet
2013-11-19T21:30:29 < TitanMKD> 848KHz mode is interesting too ;)
2013-11-19T21:30:42 < TitanMKD> TRF7970A was the 1st to support it
2013-11-19T21:31:44 < zyp> only useful for tags who support it
2013-11-19T21:31:59 < jpa-> why does every line contain a part number? :D
2013-11-19T21:32:28 < qyx_> your don't

2013-11-19T21:32:50 < TitanMKD> hehe it is just comparison
2013-11-19T21:33:00 < TitanMKD> anyway i don't work for TI
2013-11-19T21:33:08 < TitanMKD> but i like their chipset

2013-11-19T21:34:15 < TitanMKD> yes cheap like all their eval board
2013-11-19T21:34:27 < TitanMKD> the problem is the chipset alone are the price of the board ;)

2013-11-19T21:36:43 < TitanMKD> the antenna part seems very cheap

2013-11-19T21:41:38 < zyp> you're talking abut the red board now?
2013-11-19T21:41:39 < TitanMKD> I imagine not more than 3cm
2013-11-19T21:41:47 < zyp> huh?
2013-11-19T21:41:59 < TitanMKD> yes distance from the reader
2013-11-19T21:42:15 < zyp> are you talking about normal vicinity cards or the m24lr board with lcd and shit?
2013-11-19T21:42:15 < TitanMKD> tag <-> reader
2013-11-19T21:42:21 < TitanMKD> both ;)
2013-11-19T21:42:26 < TitanMKD> just to know the performances
2013-11-19T21:42:33 < zyp> because normal vicinity cards certainly have a longer range
2013-11-19T21:43:19 < zyp> hang on, I'll find the board and test the latter
2013-11-19T21:43:47 < TitanMKD> I imagine it is not more than 5cm
2013-11-19T21:43:55 < TitanMKD> especially when i see the antenna ;)
2013-11-19T21:44:12 < zyp> you just went up 2cm :p
2013-11-19T21:44:27 < TitanMKD> NFC tunning is very hard a bad design and it fail or work only at 0.1cm ;)
2013-11-19T21:44:36 < TitanMKD> or don't work at all ;)
2013-11-19T21:45:42 < TitanMKD> this parameter is very important for passive sniffer mode ;)
2013-11-19T21:46:19 < TitanMKD> very useful to debug transfer in fact not only to hack stuff
2013-11-19T21:48:57 < BrainDamage> ;) ;) ;) ;) ;) ;) ;) ;) ;) ;) ;) ;) ;) ;) ;)
2013-11-19T21:49:35 < Steffan-> hi BrainDamage. How are you today?
2013-11-19T21:49:40 < zyp> hmm, not sure where my ruler went, but eyeballing it, the m24lr board is successfully detected when it comes within 7cm or so
2013-11-19T21:50:35 < zyp> but it needs to be within 3cm or so to get enough power to power the stm8 and lcd
2013-11-19T21:51:40 < TitanMKD> ha ok

2013-11-19T21:59:36 < TitanMKD> not bad for an eval board at that price
2013-11-19T22:02:03 < zyp> anyway, I'm not interested in m24lr, I just wanted the reader :p
2013-11-19T22:02:42 < zyp> so if anyone has any use for the m24lr boards, I have a bunch I don't need
2013-11-19T22:05:58 < TitanMKD> the reader use a stm8 ?
2013-11-19T22:06:21 < zyp> no, stm32
2013-11-19T22:06:28 < TitanMKD> ha ok not bad
2013-11-19T22:06:32 < TitanMKD> i hate the stm8 ;)
2013-11-19T22:07:06 < zyp> yeah, I'm not interested in doing anything with that, that's why the red boards are worthless to me :p

2013-11-19T22:07:57 < NooM> hello
2013-11-19T22:08:13 < TitanMKD> i'm still waiting a dual cortex A7 in lqfp64 without 3D ;)
2013-11-19T22:08:35 < TitanMKD> even just 800MHz will be enough ;)
2013-11-19T22:09:04 < NooM> hey iam wondering, anyone ever used the stlink on the discovery to program another stm32 ?
2013-11-19T22:09:10 < zyp> what good is a cortex-a without external memory?
2013-11-19T22:09:19 < zyp> NooM, yes
2013-11-19T22:09:22 < TitanMKD> wiht lot of internal RAM ;)
2013-11-19T22:09:32 < zyp> NooM, that's what the SWD port is for
2013-11-19T22:09:32 < TitanMKD> external ram waste all cycle and power ;)
2013-11-19T22:09:44 < zyp> TitanMKD, dream on
2013-11-19T22:10:21 < TitanMKD> anyway BGA 256 1mm could be also very good ;)
2013-11-19T22:10:26 < zyp> on the other hand, you can get some A5 chips in LQFP
2013-11-19T22:10:29 < TitanMKD> as yes 4GB DDR could be really useful ;)
2013-11-19T22:10:39 < TitanMKD> LQFP is too big
2013-11-19T22:10:40 < zyp> like freescale vybrid
2013-11-19T22:10:56 < TitanMKD> i want something with max size 15mm ;)
2013-11-19T22:11:02 < TitanMKD> 10mm
2013-11-19T22:11:25 < TitanMKD> BGA FET256 with 1mm ball is a good alternative
2013-11-19T22:11:29 < NooM> zyp coocox tells me i have no connection. i connected pin2 to swc and pin 4 to swd, thats correct right ?
2013-11-19T22:11:35 < zyp> TitanMKD, except that's 16mm
2013-11-19T22:11:42 < TitanMKD> even 16mm is not bad ;)
2013-11-19T22:11:48 < NooM> i power my uC from the discovery, so it is same gnd
2013-11-19T22:12:00 < zyp> TitanMKD, have you seen the size differences on the different lpc4300 chips?
2013-11-19T22:12:10 < TitanMKD> yes
2013-11-19T22:12:20 < zyp> http://bin.jvnv.net/f/kyWMu.JPG
2013-11-19T22:12:30 < TitanMKD> LPC43 are just not fast for what i want to do ;)
2013-11-19T22:12:45 < zyp> doesn't matter, I'm talking package
2013-11-19T22:13:11 < TitanMKD> Yes I have also some BGA256 version here with proto PCB

2013-11-19T22:13:29 < TitanMKD> never tested with SDRAM
2013-11-19T22:13:35 < TitanMKD> does it work fine finally ?
2013-11-19T22:13:43 < zyp> dunno, didn't test either
2013-11-19T22:14:23 < zyp> I got annoyed when I was trying to come up with a sane API for the GPIO/pinmux stuff, and I haven't done anything with it since
2013-11-19T22:14:24 < TitanMKD> i'm afraid your design have not respected len for SDRAM IO
2013-11-19T22:14:32 < TitanMKD> especially > 100MHz
2013-11-19T22:14:52 < zyp> doesn't matter, lpc4300 sdram controller doesn't support speeds > 100 MHz
2013-11-19T22:15:03 < TitanMKD> of course it support

2013-11-19T22:18:51 < TitanMKD> anyway length matching is required in that case
2013-11-19T22:19:42 < zyp> they are matched
2013-11-19T22:19:56 < TitanMKD> ha ok anyway on photo it is hard to see it

2013-11-19T22:22:10 < TitanMKD> the USB 2.0HS does not like multi via
2013-11-19T22:22:32 < TitanMKD> anyway at 480MBPS i doubt that really make any problem
2013-11-19T22:23:29 < zyp> so, 100 MHz is real fast and will pose lots of problems, but 480 MHz is too slow for stuff to really matter? :)
2013-11-19T22:23:57 < fbs> 480MHz is so fast you just should stop caring
2013-11-19T22:24:13 < TitanMKD> USB 2.0HS signal is more robust than what we think ;)
2013-11-19T22:24:34 < TitanMKD> USB 3.0 is harder ... ;)
2013-11-19T22:24:54 < fbs> 4 layers should work
2013-11-19T22:24:54 < bsdfox> looks good zyp :)
2013-11-19T22:25:37 < zyp> bsdfox, sure, I just don't know what I should use it for
2013-11-19T22:25:38 < fbs> which chips are that?
2013-11-19T22:25:49 < zyp> lpc4357
2013-11-19T22:25:53 < fbs> ah
2013-11-19T22:26:39 < zyp> I made the board because I wanted to try designing with and assembling bga, and it went fine, so I kinda reached my goal there
2013-11-19T22:26:59 < zyp> and I don't really have anything useful to do with it, so it's just been sitting around since
2013-11-19T22:27:05 < TitanMKD> yes BGAFET256 1mm ball are not so hard in fact
2013-11-19T22:27:23 < TitanMKD> but BGAFET100 0.8mm are an other challenge ;)
2013-11-19T22:27:48 < TitanMKD> with route smaller than 6mil ...
2013-11-19T22:27:59 < zyp> probably still easier than 0.5mm qfn :p

2013-11-19T22:28:30 < TitanMKD> the hard part is to check BGA solder joint ;)
2013-11-19T22:28:48 < zyp> I did a design with 0.75mm bga for work some weeks ago
2013-11-19T22:29:09 < TitanMKD> and it worked ?
2013-11-19T22:29:31 < zyp> dunno, it's not finished yet, the project is currently on halt
2013-11-19T22:29:59 < TitanMKD> i was wrong FET100 is 0.7mm ;)
2013-11-19T22:30:20 < TitanMKD> it is one of smallest BGA size
2013-11-19T22:30:27 < TitanMKD> IIRC smallest is 0.65mm
2013-11-19T22:30:45 < zyp> you've never seen 0.4?
2013-11-19T22:31:02 < TitanMKD> ha there is 0.4mm balls too ?
2013-11-19T22:31:14 < zyp> sure
2013-11-19T22:31:22 < TitanMKD> haha ok ;)
2013-11-19T22:32:01 < TitanMKD> i imagine to solder that it is mandatory to do it in automatic way
2013-11-19T22:32:11 < TitanMKD> with XRAY checks ;)
2013-11-19T22:32:27 < TitanMKD> with very good quality PCB ENIG ...
2013-11-19T22:32:33 < zyp> the stm32f4 in wlcsp90 is a 0.4mm pitch grid
2013-11-19T22:32:49 < TitanMKD> ha yes the size is amazing
2013-11-19T22:32:57 < TitanMKD> but just impossible to do it by hand ;)
2013-11-19T22:33:01 < Steffan-> i wonder who uses that and for what..
2013-11-19T22:33:20 < TitanMKD> yes for ultra embedded stuff
2013-11-19T22:33:55 < zyp> Steffan-, ever opened a modern phone?
2013-11-19T22:34:07 < Steffan-> yes, but i dont expect to see a f4 in my phone :D
2013-11-19T22:34:18 < zyp> fair enough

2013-11-19T22:43:39 < fbs> just a probe is kinda useless ;)
2013-11-19T22:44:01 < TitanMKD> something like Extech EX330 have a nice Type K probe

2013-11-19T22:44:27 < TitanMKD> often with offset of 40°C ...
2013-11-19T22:44:50 < fbs> or just your own board

2013-11-19T23:52:54 < Laurenceb__> you
2013-11-19T23:52:55 < englishman> i guess i will be too :)
2013-11-19T23:53:03 < GargantuaSauce> my inner ear does a fine job of determining my orientation
2013-11-19T23:53:04 < Laurenceb__> anyone got any LSM330 sensors?
2013-11-19T23:54:43 < Laurenceb__> I'm so screwed
2013-11-19T23:54:58  * Laurenceb__ has a load of PCBs that need LSM330DL
2013-11-19T23:54:58 < GargantuaSauce> time to find a smuggler
2013-11-19T23:55:11 < Laurenceb__> its worth me flying to the US to get some....
2013-11-19T23:55:49 < Laurenceb__> prob cheaper to buy old samsung galaxies on ebay
2013-11-19T23:57:09 < Laurenceb__> guess ill probably have to do that

2013-11-19T23:58:18 < englishman> no biggie :) thanks
2013-11-19T23:58:27 < Laurenceb__> any USians here?
2013-11-19T23:58:46 < Laurenceb__> that could but some sensors for me, ill pay $$$

2013-11-19T23:59:45 < GargantuaSauce> yeah englishman i always just set SSM and SSI and then toggle the nss pin as a normal gpio
--- Day changed Wed Nov 20 2013
2013-11-20T00:00:24 < GargantuaSauce> also if you want full throughput make sure you write to DR twice before waiting on RXNE
2013-11-20T00:04:27 < zyp> NSS is only useful if you're going to use slave mode
2013-11-20T00:05:01 < GargantuaSauce> oh disregard my last message, forgot the f3 has fancy-ass FIFOs
2013-11-20T00:05:30 < zyp> «fancy»
2013-11-20T00:05:38 < zyp> it's a shitty silly implementation
2013-11-20T00:08:23 < gxti> a N-fifo is better than a 1-fifo no matter how silly
2013-11-20T00:08:36 < gxti> not required of course, but still better
2013-11-20T00:09:34 < zyp> how can it be better when it adds no real advantages and comes with disadvantages?
2013-11-20T00:09:54 < gxti> 1 context switch is faster than 4
2013-11-20T00:10:20 < zyp> if you care about SPI performance you would use DMA anyway

2013-11-20T00:15:39 < zyp> I'm mostly annoyed by the fact that you now have to special case on the word size
2013-11-20T00:16:24 < zyp> because if you try writing the full DR when it's configured to a data size <= 8, it'll put two bytes into the fifo
2013-11-20T00:16:33 < zyp> I mean, two words
2013-11-20T00:17:07 < zyp> so you have to have code for doing 8-bit writes for small data sizes, and 16-bit writes for large data

2013-11-20T02:31:30 < dongs> sup trolls
2013-11-20T02:33:39 < gxti> dead board, garbage time
2013-11-20T02:34:07 < dongs> too much debugging
2013-11-20T02:34:31 < gxti> apply power, dead short. looks like it's the gps module which seems to have shifted over half a pad. remove ferrite to gps. still short. 2 ohms across LDO. clip LDO leg. apply power. still short. fuck it garbage time!
2013-11-20T02:34:50 < dongs> ya
2013-11-20T02:34:59 < dongs> LGA sucks
2013-11-20T02:35:18 < gxti> nah that was just the first thing, after removing the ferrite i don't think it can cause the rest of the trouble
2013-11-20T02:35:33 < gxti> probably solder ball under qfn or something
2013-11-20T02:35:41 < dongs> i had a project that used a ~60 pin LGA  that was just pads on bottom of like 0.4mm thin pcb, no balls, and i could never get it to reflow without bridging
2013-11-20T02:35:44 < dongs> fucking useless
2013-11-20T02:36:11 < dongs> that kinda shit needs to be bga to work
2013-11-20T02:36:18 < gxti> this is the first out of 8 where the gps missoldered, annoying but rare enough
2013-11-20T02:36:42 < gxti> i've desoldered one before, will probably do it again
2013-11-20T02:38:08 < gxti> that one was nice, the pcb was faulty. inner layer mask was backwards. everything short.
2013-11-20T02:38:28 < gxti> i got what i paid for...
2013-11-20T02:39:19 < gxti> if i ever stop dicking with this design long enough to get a larger batch made it'll have e-test
2013-11-20T02:39:26 < qyx_> lol
2013-11-20T02:40:13 < qyx_> you can try seeed, quality seem to be good now
2013-11-20T02:41:29 < qyx_> although the chinese post is already celebrating christmas
2013-11-20T02:42:07 < gxti> or maybe even just pay someone else to assemble it, was thinking while putting these last two together that i would probably save money not fucking it up myself
2013-11-20T02:46:06 < englishman> <GargantuaSauce> also if you want full throughput make sure you write to DR twice before waiting on RXNE
2013-11-20T02:46:15 < englishman> what do you mean? even if it's not related to f3
2013-11-20T02:46:16 < GargantuaSauce> that is for the f4, disregard
2013-11-20T02:46:48 < englishman> i'm also having trouble with a DMA http://bcas.tv/paste/results/l0p7Gg18.html
2013-11-20T02:47:03 < englishman> it inits ok, but the data doesn't get copied and the interrupt doesn't fire
2013-11-20T02:47:16 < GargantuaSauce> i mean write DR, loop{ wait on TXE, write DR, wait on RXNE, read DR }, wait on RXNE, read DR
2013-11-20T02:48:21 < GargantuaSauce> havent tackled dma yet personally
2013-11-20T02:48:31 < englishman> ah i see what you mean
2013-11-20T02:50:09 < GargantuaSauce> if you don't write dr twice to start you get http://xn--d-bga.su/spigaps.png which kinda sucks
2013-11-20T02:55:09 < dongs> cool scope
2013-11-20T02:55:31 < GargantuaSauce> i know rite
2013-11-20T02:55:54 < dongs> um
2013-11-20T02:55:55 < dongs> englishman:
2013-11-20T02:56:00 < dongs> you have memory and peripheralinc disable
2013-11-20T02:56:04 < dongs> what hte fuck do you expect to transfer?
2013-11-20T02:56:42 < dongs> also if y ou're DMA'ing to GPIO I *think* you need to slave the actual clocking out from a timer or something
2013-11-20T02:56:49 < dongs> you have nothing to actually "drive" the DMA
2013-11-20T02:56:54 < englishman> it's just for testing, but i wanna transfer one uint16
2013-11-20T02:57:19 < englishman> what do you mean, "slave the actual clocking"
2013-11-20T02:57:35 < dongs> like,, how is it goign to know when to move to next byte?
2013-11-20T02:57:37 < dongs> in your setup
2013-11-20T02:57:38 < englishman> the dma get init'd elsewhere and reinit'd in the interrupt
2013-11-20T02:58:14 < englishman> this, right? DMA_Cmd(DMA1_Channel1, ENABLE);
2013-11-20T02:58:27 < dongs> no
2013-11-20T02:59:57 < dongs> trying to find wehre i had 16 uart code for F1
2013-11-20T02:59:59 < dongs> using gpio+dma
2013-11-20T03:00:26 < englishman> yeah i read that as well
2013-11-20T03:00:32 < englishman> in baseflight
2013-11-20T03:00:35 < dongs> not there.
2013-11-20T03:00:38 < englishman> ok
2013-11-20T03:01:07 < englishman> this is just a lesson for me in DMA, so i figured i'd set it up to write to that register and just step through to see if it actually worked...
2013-11-20T03:02:55 < dongs> http://bcas.tv/paste/results/Hjqfrp31.html
2013-11-20T03:04:13 < englishman> oh, there is more stuff
2013-11-20T03:04:26 < dongs> like
2013-11-20T03:04:42 < dongs> the idea is clocking out section of memory as writes to GPIO->ODR
2013-11-20T03:04:55 < dongs> so to do that, you need to drive DMA from timer
2013-11-20T03:05:17 < englishman> i thought that "enabling dma" would let it run until the copying was done
2013-11-20T03:05:31 < englishman> like this example http://www.embedds.com/using-direct-memory-access-dma-in-stm23-projects/
2013-11-20T03:05:35 < englishman> or is that M2M only?
2013-11-20T03:05:39 < dongs> m2m
2013-11-20T03:05:43 < englishman> hmmmmmmm
2013-11-20T03:06:16 < dongs> you need to figure out why you need DMA first
2013-11-20T03:06:23 < englishman> i just wanted to dick with it
2013-11-20T03:06:30 < dongs> don't dick wiht it wiht GPIO then
2013-11-20T03:06:33 < dongs> do DMA to SPI or something
2013-11-20T03:06:34 < englishman> ok :)
2013-11-20T03:06:41 < englishman> yes i would like to use it with SPI
2013-11-20T03:06:44 < dongs> or write a m2m DMA memset/memzero
2013-11-20T03:06:51 < dongs>  /memcpy
2013-11-20T03:07:05 < dongs> but setup + crap is probably more work unless  ytou're repeateadly clearning large buffers
2013-11-20T03:07:08 < dongs> like I did in OSD
2013-11-20T03:07:21 < englishman> well it's for openLRSngRx-ngng
2013-11-20T03:07:25 < englishman> 32
2013-11-20T03:07:36 < englishman> right now just dicking while i wait for stuff to be made
2013-11-20T03:08:09 < dongs> http://www.ustream.tv/channel/nasa-media-channel
2013-11-20T03:08:13 < dongs> watch another usa rocket explode
2013-11-20T03:08:14 < englishman> so it'd read frames of like 10s of bytes
2013-11-20T03:09:35 < dongs> STEP 79
2013-11-20T03:11:11 < gxti> no explosion, i was lied to
2013-11-20T03:11:20 < qyx_> t-5min?
2013-11-20T03:11:22 < qyx_> or?
2013-11-20T03:11:43 < dongs> y
2013-11-20T03:12:33 < gxti> does using too little solder paste on qfn pad cause issues? from surface tension pulling chip down or something?
2013-11-20T03:13:01 < englishman> is that why R2COM isn't here, we are busy watching him
2013-11-20T03:13:35 < gxti> i don't think they let him near the real stuff
2013-11-20T03:14:09 < qyx_> what are they trying to ignite this time?
2013-11-20T03:15:14 < gxti> fuel probably
2013-11-20T03:15:40 < qyx_> seems so
2013-11-20T03:15:43 < dongs> wow that took off fast
2013-11-20T03:15:46 < qyx_> i can see fire
2013-11-20T03:15:53 < gxti> mission accomplished

2013-11-20T12:20:18 < karlp> but manchester/nrz are _valid_ bits, and parallel is an _invalid_ bit.

2013-11-20T19:14:38 < emeb> right
2013-11-20T19:15:06 < emeb> so the "takeaway" from this is that you need to make tech more like a smartphone in order to draw kids in.
2013-11-20T19:15:27 < GargantuaSauce> yeah the whole "let's make programming more accessible" thing kind of baffles me
2013-11-20T19:15:46 < emeb> if you need to dumb it down then these aren't the kids you're looking for.
2013-11-20T19:16:14 < GargantuaSauce> because fundamentally it's a clusterfuck and the more you shield people from that the further they are from being to come to terms with that
2013-11-20T19:16:56 < emeb> yep
2013-11-20T19:17:04 < madist> but Java!

2013-11-20T19:49:47 < GargantuaSauce> i find the f0 discovery pretty amusing
2013-11-20T19:50:19 < GargantuaSauce> considering that the f1 for the stlinkv2 is more powerful
2013-11-20T19:50:44 < BrainDamage> the F100 discovery is the same and it was the first discovery
2013-11-20T19:50:57 < BrainDamage> the target chip is a f101, the stlink chip is a f103
2013-11-20T19:51:35 < bsdfox> the f0 chip is good :)

2013-11-21T08:49:35 < talsit> if i set it to OUTPUT on startup, my MCU freezes up, but if i set it to INPUT, it's all good
2013-11-21T08:49:48 < emeb_mac> bizarre
2013-11-21T08:50:00 < talsit> well... i'm reading that it's set to JTDI on startup
2013-11-21T08:50:07 < talsit> but i'm access it via SWD
2013-11-21T08:50:16 < talsit> hmmm... how do i turn off JTAG
2013-11-21T08:51:12 < dongs> PA15?
2013-11-21T08:51:20 < dongs> right, reset it as GPIO
2013-11-21T08:51:43 < dongs> AFIO->MAPR |= AFIO_MAPR_SWJ_CFG_NO_JTAG_SW; <some equivalent of this on F4
2013-11-21T08:51:57 < emeb_mac> thats it
2013-11-21T08:53:02 < talsit> isn't that the code for the F103-stype remapping?
2013-11-21T08:53:44 < dongs> "equivalent of that for F4"
2013-11-21T08:53:50 < dongs> fucking look in stdperiphlib and find the function call.
2013-11-21T08:54:04 < dongs> im to lazy to dig out my F4 project wehre i turned off SWD
2013-11-21T08:54:17 < talsit> so, the answer is "yes" ... got it
2013-11-21T08:55:02 < talsit> it looked familiar to what i was doing on my F103, hence me asking

2013-11-21T20:41:11 < karlp> that's interesting.
2013-11-21T20:41:26 < Tectu> I agree, and I'm amazed and impressed by your work
2013-11-21T20:41:33 < Tectu> never the less, what's that music player? :D
2013-11-21T20:45:12 < Steffan-> you're using the st-link for that no karlp?
2013-11-21T20:45:15 < Steffan-> but nice nice :D
2013-11-21T20:45:50 < karlp> yeah, stlinkv2 on a disco board targetting our board
2013-11-21T20:46:35 < Tectu> what's the bandwidth
2013-11-21T20:46:51 < karlp> 2Mhz, but that has to include framing packets,
2013-11-21T20:47:03 < karlp> so it sort of depends what you're writing, and whether you're including timing info or not
2013-11-21T20:48:18 < Steffan-> should still play around with swo and the bmp

2013-11-21T20:50:49 < karlp> theoretically it can go faster, gsmcmullin apparently implemented manchester decoding, but I don't actually know at all what limits his is capable of
2013-11-21T20:50:57 < karlp> also, this doesn't require any hacking on the baords
2013-11-21T20:51:28 < karlp> I'm writing about 5kbytes/sec at the moment, so not an awful lot, but it's non-intrusive
2013-11-21T20:52:37 < gxti> emeb: how much use do you figure the 20-pin jtag on bmp2 gets?
2013-11-21T20:53:07 < emeb> gxti: virtually none I'd guess
2013-11-21T20:53:24 < emeb> I only put it on there for zyp and I'm not sure he uses it.
2013-11-21T20:54:03 < gxti> i'm making an isolated bmp and i've got an extra output, was going to put trst on it but only the 20 pin connector even has trst
2013-11-21T20:54:04 < emeb> I mainly use the 6-pin and 10-pin mini
2013-11-21T20:54:34 < Steffan-> 6 pin is non-standard i guess?
2013-11-21T20:54:59 < emeb> 6-pin is widespread, but only on Discovery boards.
2013-11-21T20:55:17 < Steffan-> oh six in a row :)
2013-11-21T20:55:18 < gxti> i will probably just have those two then
2013-11-21T20:55:37 < gxti> plus a 3 pin header for uart
2013-11-21T20:55:47 < emeb> that uart is handy
2013-11-21T20:55:56 < emeb> esp if you can't be arsed to figure out SWO
2013-11-21T20:56:12 < gxti> i laid things out so there are 3 isolator ICs, and one of them can be unpopulated to leave off uart and save a few bucks
2013-11-21T20:56:26 < gxti> hence the extra output i was going to use for trst
2013-11-21T20:56:28 < Steffan-> why go isolated gxti?

2013-11-21T21:04:22 < emeb> what does tagconnect have on the non-target end? 10-pin mini?
2013-11-21T21:04:51 < gxti> i think so, i  haven't bought one yet. unfortunately digikey does not stock the cortex ones.

2013-11-21T21:05:51 < zyp> emeb, the cortex variant has a mini-10 yes
2013-11-21T21:06:12 < emeb> cool - so it works with the stuff we've already got.
2013-11-21T21:06:24 < zyp> 19:53:24 < emeb> I only put it on there for zyp and I'm not sure he uses it.
2013-11-21T21:06:27 < zyp> used it yesterday
2013-11-21T21:06:29 < zyp> ;)
2013-11-21T21:06:36  * emeb feels validated
2013-11-21T21:06:55 < zyp> so yeah, it's certainly useful
2013-11-21T21:06:56 < gxti> not sure if i even want to make it a 'mini' adapter, or go for the full jlink style enclosure
2013-11-21T21:07:00 < emeb> saw a picture you posted of a BMP2 with no 20-pin soldered on.
2013-11-21T21:07:30 < zyp> I've only soldered it to one of them
2013-11-21T21:07:33 < gxti> having bare pcbs suspended in midair on IDC ables seems suboptimal

2013-11-21T21:08:17 < zyp> gxti, that's why I shrinkwrapped my old original bmp
2013-11-21T21:08:35 < zyp> I should probably do that to the bmp2s too
2013-11-21T21:08:48 < zyp> they are hanging uncomfortably close to metal parts some times
2013-11-21T21:09:04 < emeb> 3D print little cases for them with appropriate cutouts.
2013-11-21T21:09:35 < zyp> I'm still annoyed by the stlink style headers being sharp
2013-11-21T21:09:54 < zyp> I ought to assemble a board with only mini-10 and 20 and shrinkwrap it
2013-11-21T21:11:11 < Steffan-> is there any functional difference between the bmp and bmp2 btw?
2013-11-21T21:11:28 < zyp> no, bmp2 is same circuit as bmpm
2013-11-21T21:12:18 < emeb> except for the UART and SWD aren't hooked together as on the BMPM
2013-11-21T21:12:34 < zyp> ah, true
2013-11-21T21:13:10 < Steffan-> i have the one before the bmpm :)

2013-11-21T23:33:23 < GargantuaSauce> still only works on A

2013-11-22T00:55:08 < zyp> just discovered that the bootloader on the 30+ boards I've shipped seems to have problems enumerating on windows
2013-11-22T00:57:08 < emeb> home-grown bootloader?
2013-11-22T00:57:18 < zyp> yes, HID based
2013-11-22T00:57:30 < emeb> no fun
2013-11-22T00:57:41 < zyp> I think maybe windows doesn't like my report descriptor
2013-11-22T00:57:54 < emeb> stupid winders
2013-11-22T00:58:56 < zyp> main reason I went with hid at all was to have a no-hassle upgrade available on windows :p

2013-11-22T00:59:47 < zyp> «download exe, doubleclick it» is what I was aiming for
2013-11-22T01:00:03 < emeb> laudable
2013-11-22T01:00:26 < zyp> made a precompiled exe that I can just put in the firmware repo and append a firmware to when building it

2013-11-22T01:01:43 < zyp> should be a number of workarounds
2013-11-22T01:02:26 < zyp> either find a computer with a different os, or bind it to winusb and access it through libusb instead or something

2013-11-22T01:09:08 < zyp> then they can flash an upgrader
2013-11-22T01:09:17 < zyp> that would overwrite the bootloader when it runs

2013-11-22T02:40:01 < Steffan-> price wise or .. package wise R0b0t1?
2013-11-22T02:40:14 < zyp> it's not DIP
2013-11-22T02:40:39 < zyp> and there's no built in CAN transciever, like lpc11c :p
2013-11-22T02:40:55 < zyp> the latter is one reason I'd be interested in NXP
2013-11-22T02:42:10 < Steffan-> tssop is ok too :)

2013-11-22T02:46:44 < R0b0t1> I think the shittiest one of those goes for $.30?

2013-11-22T03:13:59 < dongs> 48 tarduinos on a single board.

2013-11-22T05:16:26 < dongs> oo
2013-11-22T05:16:31 < dongs> my chromebook dixel LCD cables arrive today
2013-11-22T05:16:36 < dongs> and i dont even have a board made for it :)
2013-11-22T05:16:38 < dongs> er :(
2013-11-22T05:16:47 < emeb_mac> slow dongs
2013-11-22T05:17:56 < Steffan-> work harder you mean... it's not a good sign when the postal service is faster than you ;)
2013-11-22T05:20:25 < dongs> dixus4 standby for 3 days and like 60% battery left.
2013-11-22T05:20:27 < dongs> of course im not using it at all.
2013-11-22T05:21:09 < dongs> doesnt help that ive been sick all this week.,
2013-11-22T05:27:22 < ds2> anyone layed out a ethernet board before?
2013-11-22T05:27:41 < gxti> maybe
2013-11-22T05:27:43 < emeb_mac> talk to gxti - he does ethernet all the time
2013-11-22T05:27:56 < dongs> nothign special about ethernet, isnt it
2013-11-22T05:28:01 < gxti> not really
2013-11-22T05:28:22 < ds2> do you put ground planes under the magnetics?
2013-11-22T05:28:47 < ds2> nothing special other then that bastard not working :D
2013-11-22T05:28:51 < gxti> functionally it makes no difference that i know of
2013-11-22T05:29:06 < gxti> could matter for clearance / isolation
2013-11-22T05:29:16 < dongs> i dont think ground or not under stuff would make much diff
2013-11-22T05:29:21 < dongs> not to the point of it not working anyway.
2013-11-22T05:29:27 < dongs> 25mhz clock for phy?
2013-11-22T05:29:32 < gxti> i'm using magjacks and at the moment it's filled under
2013-11-22T05:29:34 < ds2> seems there are some app notes that say no ground plane under them
2013-11-22T05:29:49 < ds2> I am forcing it to 10baseT so 2.5MHz
2013-11-22T05:29:52 < dongs> yeah , why didnt you just use magjack
2013-11-22T05:29:57 < dongs> why separate shit
2013-11-22T05:30:02 < ds2> customer issues :D
2013-11-22T05:30:04 < dongs> pft
2013-11-22T05:30:26 < ds2> something is giving me a 3DB drop in signal from the copper side to the phy side
2013-11-22T05:30:34 < ds2> trying to locate what is eatting that signal
2013-11-22T05:31:39 < ds2> only thing that comes to mind is the transformer is coupling it it ground
2013-11-22T05:40:37 < dongs> did you use external transofrmer AND magjack?
2013-11-22T05:40:37 < dongs>  :)
2013-11-22T05:40:46 < ds2> no :P
2013-11-22T05:40:55 < ds2> the "jack" right now is a piece of CAT5
2013-11-22T05:41:06 < ds2> with a rj45 plug crimped onto it
2013-11-22T05:41:42 < dongs> heh
2013-11-22T05:42:59 < ds2> i did noticed most boards don't have a ground plane under the magnetics/jack
2013-11-22T05:43:53 < gxti> and it's due to EMI/isolation reasons, not something that would cripple your transceiver.

2013-11-22T17:54:15 < fbs> dunno about the board, but you cant produce f4 disco for the price st can
2013-11-22T17:54:23 < dongs> yes and?
2013-11-22T17:54:24 < dongs> so why bother.

2013-11-22T17:57:33 < fbs> why?
2013-11-22T17:57:52 < fbs> mathematica is actually nice
2013-11-22T17:58:22 < gxti> so run it on a real computer
2013-11-22T17:58:49 < jpa-> that's why they give it free; rpi is slow enough that it won't compete with real mathematica licenses
2013-11-22T17:59:11 < fbs> also more vendor lockin
2013-11-22T18:00:07 < dongs> wait waht
2013-11-22T18:00:16 < dongs> they have a freetartd version that ONLY runs on shittyberrypi?
2013-11-22T18:00:19 < dongs> fucking cunts.
2013-11-22T18:00:25 < gxti> yeah they know it's useless so no loss
2013-11-22T18:00:35 < Laurenceb> lol
2013-11-22T18:00:36 < gxti> it probably goes faster in a VM on a real PC
2013-11-22T18:00:47 < Lux> I wonder if it'll also work on a beagle bone black
2013-11-22T18:00:54 < Laurenceb> no
2013-11-22T18:00:55 < jpa-> i bet it has some hidden code that will check for rpi hardware
2013-11-22T18:01:02 < Laurenceb> armv7 versus armv6
2013-11-22T18:01:14 < Laurenceb> actually
2013-11-22T18:01:25 < Laurenceb> its probably not thumb?
2013-11-22T18:01:28 < Laurenceb> so might run
2013-11-22T18:02:25 < Laurenceb> you'll have to try it
2013-11-22T18:02:54 < Lux> yeah, but I guess running it on a proper pc is more fun :)
2013-11-22T18:03:01 < Lux> esp if you get a free lic anyway
2013-11-22T18:04:55 < Laurenceb> haha reddit has a pegging subreddit
2013-11-22T18:05:08 < Laurenceb> that tells you a lot about reddit
2013-11-22T18:05:40 < gxti> yes it tells you that they let literally anyone create them
2013-11-22T18:06:24 < Steffan-> is it dr Laurenceb yet btw?
2013-11-22T18:06:37 < Laurenceb> not yet, corrections...
2013-11-22T18:08:22 < fbs> so i cant get pills from you yet?
2013-11-22T18:08:39 < Laurenceb> sure i can get you pills
2013-11-22T18:09:13 < jpa-> he'll make you peg for the pills

2013-11-22T18:14:07 < dongs> Is there a way of getting hold of the codebase that deals with the camera module before getting the actual camera?

2013-11-22T23:43:44 < TitanMKD> for those interested to see the board partially populated
2013-11-22T23:43:45 < TitanMKD> http://bvernoux.free.fr/hw/STM32F4Board_Top_Bottom.jpg
2013-11-22T23:43:55 < TitanMKD> missing main part STM32F4 and some caps ..
2013-11-22T23:45:08 < mtbg> why two usb ports?
2013-11-22T23:45:10 < mtbg> one for host?

2013-11-22T23:50:17 < TitanMKD> for multipurpose ;)
2013-11-22T23:50:55 < TitanMKD> like connecting a powerbank on one and using the 2nd as USB or even usb both 1 Host and 1 Device
2013-11-22T23:51:55 < TitanMKD> USB1 is also used as DFU
2013-11-22T23:52:09 < TitanMKD> as USB2 is OTG so it can act as device or host
2013-11-22T23:54:54 < TitanMKD> also the extension/shield board for it for lowlevel NFC
2013-11-22T23:54:55 < TitanMKD> http://bvernoux.free.fr/hw/NFC_ForSTM32F4.jpg
2013-11-22T23:56:28 < mtbg> some nxp chip for nfc?
2013-11-22T23:56:36 < TitanMKD> no
2013-11-22T23:56:43 < TitanMKD> TRF7970A from TI
2013-11-22T23:57:11 < TitanMKD> support all 13.56Mhz protocol and even more
2013-11-22T23:57:16 < mtbg> the silkscreen is crappy indeed
2013-11-22T23:57:20 < TitanMKD> @ up to 848KHz
2013-11-22T23:57:27 < TitanMKD> yes the silkscreen is ugly
2013-11-22T23:57:42 < TitanMKD> it is the 1st time i receive so bad silkscreen
2013-11-22T23:57:52 < TitanMKD> anyway it is just proto for test
2013-11-22T23:58:15 < mtbg> nice
2013-11-22T23:58:21 < mtbg> it can both act as a reader
2013-11-22T23:58:26 < TitanMKD> of course
2013-11-22T23:58:26 < mtbg> and emulate a transponder
2013-11-22T23:58:30 < TitanMKD> yes ;)
2013-11-22T23:58:34 < TitanMKD> and also sniffer ;)
2013-11-22T23:58:47 < TitanMKD> and also working in autonomous mode
2013-11-22T23:58:59 < TitanMKD> it is why there is some led and buttons
2013-11-22T23:59:06 < zyp> and it's still utter shit if you don't want to do SDR NFC
2013-11-22T23:59:25 < TitanMKD> actual FW already does SDR NFC ;)
2013-11-22T23:59:54 < TitanMKD> sniffinf PCD and PICC and logging it in clear ASCII ;)
--- Day changed Sat Nov 23 2013
2013-11-23T00:00:28 < TitanMKD> in fact we can just do like proxmark3 but all in SW
2013-11-23T00:00:41 < TitanMKD> and about 5 times cheaper
2013-11-23T00:00:48 < TitanMKD> and portable ;)
2013-11-23T00:01:24 < TitanMKD> i will populate the 2 board this week end for test
2013-11-23T00:02:46 < TitanMKD> developers are welcome i will provide free PCB populated for those motivated to participate on FW ...
2013-11-23T00:03:02 < TitanMKD> even if i will provide a fully usable FW

2013-11-24T14:12:56 < dongs> and i look at it in peripheral watch window in debugger and CNTH/L is zeros
2013-11-24T14:13:00 < dongs> um just swd reset
2013-11-24T14:13:07 < dongs> maybe via nrst, i dont really check
2013-11-24T14:13:12 < dongs> it shouldnt matter either way right?

2013-11-24T14:14:38 < dongs> right, the only diff i have is since im to lazy to make new board im using LSI
2013-11-24T14:14:44 < PaulFertser> But can you access its registers before enabling in RCC?

2013-11-24T14:17:52 < jpa-> dongs: how does your RCC->BDCR look after reset?
2013-11-24T14:17:57 < dongs> lets see
2013-11-24T14:18:07 < fbs> wonder if i need diffcode with a rtc battery
2013-11-24T14:18:18 < PaulFertser> I run         RCC_APB1PeriphClockCmd(RCC_APB1Periph_PWR, ENABLE);
2013-11-24T14:18:18 < PaulFertser>         RCC_APB1PeriphClockCmd(RCC_APB1Periph_BKP, ENABLE);
2013-11-24T14:18:24 < PaulFertser> On F1
2013-11-24T14:18:40 < jpa-> yeah.. looks like it's probably the RCC_APB1Periph_BKP  that you are missing
2013-11-24T14:18:50 < dongs> RCC->BDCR
2013-11-24T14:18:50 < dongs> 0x00008200
2013-11-24T14:18:51 < dongs> ?
2013-11-24T14:18:59 < dongs> PaulFertser: ya same
2013-11-24T14:19:15 < dongs> i ripped rtc still from some old stm32 demo code + confirmed similar function with stdperiph sampels
2013-11-24T14:19:53 < jpa-> dongs: hmm, BDCR looks ok
2013-11-24T14:20:22 < dongs> for after reset?
2013-11-24T14:20:41 < jpa-> for either; the BDCR should be unaffected by reset
2013-11-24T14:20:41 < dongs> wehre the fuck is BDCR used?
2013-11-24T14:20:47 < dongs> oh sure.
2013-11-24T14:20:51 < dongs> but its checking RTC->CRL
2013-11-24T14:20:52 < jpa-> it configures the RTC to use LSI
2013-11-24T14:20:53 < dongs> for 0x29
2013-11-24T14:21:42 < dongs> http://i.imgur.com/G0R1DT7.png
2013-11-24T14:21:54 < dongs> left = before reset, right, after i reset to start from beginning
2013-11-24T14:22:04 < dongs> RSF+SECF gets cleared
2013-11-24T14:22:06 < dongs> in CR
2013-11-24T14:22:15 < dongs> and CNTH/L as well
2013-11-24T14:22:20 < dongs> which means it loses whatever current time
2013-11-24T14:22:54 < dongs> (clock stays enabled)
2013-11-24T14:23:25 < dongs> and this is before going to init vector, so no extra crap has run
2013-11-24T14:23:30 < dongs> halt at startupo
2013-11-24T14:24:03 < jpa-> so what *has* run at that point?
2013-11-24T14:24:12 < dongs> nothing at all
2013-11-24T14:24:15 < dongs> reset + halt
2013-11-24T14:24:26 < jpa-> not even the RCC_APB1PeriphClockCmd()?
2013-11-24T14:24:31 < dongs> right
2013-11-24T14:24:37 < dongs> as you see clock stays on
2013-11-24T14:24:52 < dongs> (and i can confirm it in rcc  regs
2013-11-24T14:25:17 < jpa-> uh.. the RCC registers should reset..
2013-11-24T14:25:31 < dongs> not backup power domain?
2013-11-24T14:25:33 < jpa-> i mean, the APB1 clock should reset
2013-11-24T14:25:43 < dongs> well sure, but not the fact that RTC is on?
2013-11-24T14:25:49 < jpa-> BDCR keeps value but APB1ENR does not
2013-11-24T14:25:59 < jpa-> and if the APB1 clock is off, the registers will read crap
2013-11-24T14:26:36 < dongs> RCC_APB1PeriphClockCmd(RCC_APB1Periph_PWR | RCC_APB1Periph_BKP, ENABLE); these?
2013-11-24T14:26:49 < jpa-> yeah
2013-11-24T14:26:57 < dongs> right
2013-11-24T14:26:59 < dongs> but i step tehre
2013-11-24T14:27:02 < dongs> and turn them on
2013-11-24T14:27:08 < dongs> and rtc periph is still same shit
2013-11-24T14:27:30 < PaulFertser> I remember we had to use LSE on F1 board instead of LSI but I do not remember why.
2013-11-24T14:27:36 < dongs> heh
2013-11-24T14:31:24 < PaulFertser> I remember it now: F1 has a dedicated Vbat pin and we needed the RTC to continue ticking when the main power is off, that's why.
2013-11-24T14:31:43 < dongs> ya?
2013-11-24T14:32:11 < PaulFertser> RM0008 7.2.8
2013-11-24T14:32:30 < dongs> right, but how is that a problem if it does have a dedicated vbat?

2013-11-24T14:33:12 < PaulFertser> We connected a Li battery to Vbat and the main supply to Vcc, but needed the clock to work even with main supply off.
2013-11-24T14:33:17 < dongs> oh
2013-11-24T14:33:21 < dongs> only LSE is in backup domain
2013-11-24T14:33:31 < PaulFertser> Yep
2013-11-24T14:33:33 < dongs> i wonder if that why it dies over reset
2013-11-24T14:34:19 < jpa-> pretty strange that it loses time, would make more sense for it just to stop counting while LSE is off
2013-11-24T14:34:42 < dongs> LSE->LSI change is just like 3 lines
2013-11-24T14:34:53 < dongs> anyone wanna try it to see if im not insane? :) hehe

2013-11-24T14:58:01 < Laurenceb__> is this over SDIO?

2013-11-24T15:01:53 < Laurenceb__> card is always in, so no
2013-11-24T15:01:58 < Laurenceb__> power handing is a pity
2013-11-24T15:02:08 < Laurenceb__> USB cables bounce all over the place
2013-11-24T15:02:40 < dongs> this board had it switchable so i had to try
2013-11-24T15:02:46 < Laurenceb__> and win/linux/osx all do different USB states as they connect

2013-11-24T15:07:15 < Laurenceb__> it seems to be moisture on the board
2013-11-24T15:07:26 < dongs> you need some of talsit's conformal coating
2013-11-24T15:07:29 < Laurenceb__> then gold contacts versus solder/pcb
2013-11-24T15:07:32 < Laurenceb__> yeah
2013-11-24T15:07:38 < dongs> tho i guess that wouldnt do shit to actual pads

2013-11-24T15:08:17 < Laurenceb__> no failures yet, looks like its slow enough for the cards to last ~4 years

2013-11-24T16:25:36 < dongs> So these guys went directly to China to pick and choose leftover parts to build a (small) smartphone to strap onto your wrist. I'm sorry, they lost me at "paradigm shift." If you re-define smartwatch to mean smartphone strapped onto your wrist, then, where's the innovation?
2013-11-24T16:25:40 < dongs> lmfao
2013-11-24T16:26:49 < BrainDamage> apple did the same with tablets and got same praises
2013-11-24T16:27:03 < dongs> apple didnt do shit with tablets
2013-11-24T16:27:16 < dongs> tablet pcs were around way before apple even switched to intel

2013-11-24T16:27:23 < dongs> nothing changed

2013-11-24T16:58:23 < dongs> zyp, does MSC have some limitations on vendor/product IDs lengths?
2013-11-24T16:59:03 < zyp> you mean manufacturer/product strings?
2013-11-24T16:59:30 < zyp> I don't know of any
2013-11-24T16:59:35 < jpa-> USB doesn't, but the SCSI layer does
2013-11-24T16:59:40 < dongs> something keil calls USBD_MSC_INQUIRY_DATA
2013-11-24T16:59:56 < zyp> ah, that's SCSI
2013-11-24T17:00:00 < dongs> zyp no not product id strings
2013-11-24T17:00:02 < jpa-> windows shows the partition table name in explorer, usb ids when you plug it in and scsi ids when you look in hardware manager, IIRC :)
2013-11-24T17:00:11 < dongs> right
2013-11-24T17:01:18 < jpa-> IIRC the limit for manufacturer name in SCSI was 8 character or other ridicuously short

2013-11-24T17:14:41 < dongs> ugh
2013-11-24T17:14:51 < dongs> fucking fatFS typedef'ing BOOL
2013-11-24T17:15:03 < dongs> typedef bool BOOL;
2013-11-24T17:15:06 < dongs> stupid fucking trash

2013-11-24T17:16:25 < TitanMKD> dongs: yes but it is a new revision that i will produce at seeed 100 boards first
2013-11-24T17:16:39 < TitanMKD> now it is time to test micro sd in SDmode 4bits
2013-11-24T17:17:36 < dongs> http://i.imgur.com/h2RkPRj.jpg i was just testing SD on a old f1 board i made last year
2013-11-24T17:17:49 < TitanMKD> ha nice
2013-11-24T17:17:57 < TitanMKD> I'm testing last Class10 SD ;)
2013-11-24T17:18:04 < TitanMKD> I have bought 2 yesterday
2013-11-24T17:19:00 < TitanMKD> especially a Sandisk Ultra 8GB UHS ;)
2013-11-24T17:19:17 < dongs> whats the point of UHS on hardware that doesnt support it?
2013-11-24T17:19:36 < TitanMKD> the point is it is the fastest on SD Mode ;)
2013-11-24T17:19:46 < TitanMKD> 10MB/s Write
2013-11-24T17:20:11 < TitanMKD> anyway UHS1 is compatible with SD mode too
2013-11-24T17:20:53 < dongs> ugh i gotta figure out how the fuck im gonna un fuck this fatfs BOOL thing

2013-11-24T17:28:49 < dongs> ill upgrade once everything works
2013-11-24T17:28:50 < dongs> this is 0.08
2013-11-24T17:29:01 < jpa-> ah, maybe that's why
2013-11-24T17:29:12 < jpa-> what trouble does it cause anyway?
2013-11-24T17:29:20 < dongs> none, it fucks with keil RTL/RL_USB shit
2013-11-24T17:29:24 < dongs> since that ALSO defines a BOOL
2013-11-24T17:29:33 < jpa-> do they typedef a different BOOL?
2013-11-24T17:29:36 < dongs> yea
2013-11-24T17:29:46 < dongs> i just changed the ~8 places in code where it was being used anyway, problem solved
2013-11-24T17:29:53 < dongs> and just using proper <stdbool.h> bool
2013-11-24T17:29:56 < jpa-> yeah, probably easiest
2013-11-24T17:30:02 < dongs> and let RTL #define whatever teh fuck they wanted
2013-11-24T17:30:09 < dongs> i think they made it a unsigned short or something for bool
2013-11-24T17:30:48 < dongs> k i got a msc device in device manager
2013-11-24T17:31:02 < jpa-> IMO the people who make bool be 16 bits on 32 bit platform are the craziest.. i can understand 32bit and 8bit :P
2013-11-24T17:31:03 < dongs> but i didnt implement any disk read/write stuffs yet
2013-11-24T17:31:18 < dongs> i kno rite
2013-11-24T17:31:25 < dongs> acutally no, tehy did make it 32bit
2013-11-24T17:31:29 < dongs> typedef unsigned char   BIT;
2013-11-24T17:31:29 < dongs> typedef unsigned int    BOOL;
2013-11-24T17:31:31 < dongs> thats from RTL

2013-11-25T02:08:36 < dongs> for APB
2013-11-25T02:08:37 < dongs> so..
2013-11-25T02:08:39 < dongs> spi is /2
2013-11-25T02:08:42 < dongs> 18
2013-11-25T02:08:45 < Laurenceb__> ah so fast
2013-11-25T02:09:01 < Laurenceb__> i run at 9
2013-11-25T02:10:06 < Laurenceb__> youll prob only see ~40% speed increase by interleaving the spi and usb
2013-11-25T02:12:15 < Laurenceb__> i couldnt get 18mhz to work on 0.8mm boards
2013-11-25T02:12:22 < Laurenceb__> works fine on 1.6mm

2013-11-25T12:40:56 < Laurenceb> now i cant lock the admin directory

2013-11-26T01:58:28 < upgrdman> the hp 34401a bench meter retails for $1100ish new. what would be a good price for a used one, in good condition, with probes?
2013-11-26T02:03:12 < dongs> you mean y ou found some test equipment that hasnt been obsolete for a decade?

2013-11-26T02:04:20 < upgrdman> dongs: i know the 34401a is obsolete, but i cant afford new...
2013-11-26T02:05:06 < dongs> well its still listed on agilent as in existence
2013-11-26T02:05:11 < gxti> 34461a is a direct replacement
2013-11-26T02:05:11 < dongs> is what i meant
2013-11-26T02:05:22 < dongs> i'd have expected  you to find something a bit more obsolete
2013-11-26T02:05:29 < gxti> it's not really an 'upgrade' though, other than that it's made of less old shit
2013-11-26T02:05:36 < gxti> nothing wrong with the old one
2013-11-26T02:05:37 < dongs> gxti: you want any neo6m's? now that im have neo7 i dont really have any use for them
2013-11-26T02:05:41 < gxti> dongs: sure
2013-11-26T02:06:35 < upgrdman> well ya, its still sold as new
2013-11-26T02:07:06 < upgrdman> i just want to buy one bench dmm that will last me. and i have some spare cash, so i dont mind spending for something beyond my needs, if the price is right
2013-11-26T02:07:24 < gxti> that's pretty weird since 34461a is not only a direct upgrade but it has some of the same weird limitations as 34401a just so that lazy companies don't have to retool their test racks or whatever
2013-11-26T02:07:32 < upgrdman> so use, in good condition, what might be a decent price for a 34401a?
2013-11-26T02:07:38 < dongs> i have no issues wiht my fluke 73
2013-11-26T02:08:23 < dongs> i dont think i ever wanted more than 2 digits accuracy
2013-11-26T02:08:39 < dongs> and ive had that shit since like '96
2013-11-26T02:08:45 < dongs> only needed to replace batteries twice

2013-11-26T11:33:48 < dongs> unless youre using some shit from 1996

2013-11-26T14:47:49 < zyp> just that I had a valid ticket
2013-11-26T14:53:30 < jpa-> in the trains when you cross the border they check the passport only if you look criminal enough
2013-11-26T14:54:43 < dongs> hello bloggers
2013-11-26T14:55:25 < Steffanx> and did you qualify jpa-?
2013-11-26T14:55:31 < jpa-> no :(
2013-11-26T14:55:55 < zyp> last time I was travelling I flew to denmark and took a train to sweden, was no passport control anywhere
2013-11-26T14:58:27 < zyp> of course, that's all within schengen

2013-11-26T17:07:48 < zyp> heh, RS mailed me, asking for me to fill out the export form again
2013-11-26T17:08:52 < karlp> Thorn: they've been third party cores for teh entire pic32 line,
2013-11-26T17:09:19 < karlp> this is just the first one that's microaptive, which is mips newest part, targetting lower down against cortex m
2013-11-26T17:09:37 < karlp> took a 5h domestic flight in oz if we're going to get into that argument

2013-11-26T17:11:36 < Thorn> is that the 'cortex-m killer' core that was discussed here a year ago or so?
2013-11-26T17:11:48 < dongs> i doubt it'll kill anything since its mips
2013-11-26T17:12:02 < BrainDamage> it'll kill itself
2013-11-26T17:12:03 < Thorn> I wonder if they offer any usable and free toolchains.
2013-11-26T17:12:12 < dongs> doubtful
2013-11-26T17:12:18 < Thorn> and if the debug interface is standard
2013-11-26T17:12:25 < dongs> EJTAG and some "4 wire debug"
2013-11-26T17:12:27 < BrainDamage> and if they are cheap
2013-11-26T17:12:27 < dongs> doesnt sound like it
2013-11-26T17:12:34 < dongs> $7 in 10k qty doesnt sound cheap

2013-11-26T17:19:49 < Thorn> they're imitating ARM in everything.
2013-11-26T17:20:14 < trepidaciousMBR> People still seem to use MIPS, I've always wondered why since it seems like a pain in the ass
2013-11-26T17:20:28 < trepidaciousMBR> Maybe just if you are used to them, you will carry on, like with AVR?
2013-11-26T17:27:41 < Thorn> a friend with an imgtec login says that the manuals for the core are 500 Internal Server Error

2013-11-26T19:48:57 < PaulFertser> Laurenceb: it should reset jtag test circuity only but on some devices it messes other parts. No real reason to use it as it's equivalent to doing 5 TCK pulses with TMS low according to the jtag state diagram.
2013-11-26T19:50:37 < Laurenceb> i see
2013-11-26T19:54:40 < trepidaciousMBR> Is there any reason the datasheet for the 42x/43x divides the non-core-coupled SRAM into 3 areas? Can you DMA across the boundaries etc?

2013-11-26T23:54:52 < mattbrejza> hey, anyone know the best way to write like 300 bytes every few seconds to sd card? will opening, writing, closing wear it out?
2013-11-26T23:57:48 < fbs> its the writing that kills it
2013-11-26T23:57:57 < zyp> I would assume that the wear levelling on the card should take care of evening out the wear whatever you do
2013-11-26T23:58:08 < fbs> do all cards have wear leveling?
2013-11-26T23:58:32 < mattbrejza> persumably keeping the file open will make it less worse?
2013-11-26T23:58:44 < fbs> no
2013-11-26T23:59:04 < mattbrejza> not even the bit the file system sits in?
2013-11-26T23:59:09 < zyp> fbs, dunno, there are probably some around without
2013-11-26T23:59:31 < zyp> mattbrejza, the metadata is wear levelled along with everything else
2013-11-26T23:59:33 < fbs> is it overwriting or new data?
2013-11-26T23:59:37 < zyp> wear is wear
2013-11-26T23:59:46 < mattbrejza> new data
--- Day changed Wed Nov 27 2013
2013-11-27T00:00:41 < fbs> guess you could just replace the card every year
2013-11-27T00:00:49 < zyp> mattbrejza, what is your use case? is wear really a concern?
2013-11-27T00:01:17 < mattbrejza> well i was running it for a while last night, and now the sd card is a bit screwed
2013-11-27T00:01:33 < fbs> 300 bytes every 5 second is 3.5kb/minute, 2GB / year
2013-11-27T00:01:48 < zyp> heh, that's nothing
2013-11-27T00:01:49 < mattbrejza> i tried to do a raw dump of the sd card but it failed at the same place after 4MB
2013-11-27T00:01:51 < fbs> that shouldnt kill a card
2013-11-27T00:02:10 < fbs> should have altaest 100 writes
2013-11-27T00:02:22 < mattbrejza> i thought that perhaps rewriting the same file system spot wouild cause errors
2013-11-27T00:02:40 < fbs> if you add new data your arent writing to the same spot
2013-11-27T00:03:16 < zyp> mattbrejza, you shouldn't have to worry about it
2013-11-27T00:03:34 < mattbrejza> well thedata goes to a different spot, but every time you add data the file size has to be updated?
2013-11-27T00:03:42 < zyp> unless you are interfacing directly with raw nand chips, you probably already have a nand controller that does wear levelling for you
2013-11-27T00:03:48 < mattbrejza> but if you say dont worry ill try another card
2013-11-27T00:04:00 < fbs> i think getting a decent card is more important
2013-11-27T00:04:05 < zyp> yes
2013-11-27T00:04:31 < mattbrejza> well this is a sandisk one (in theory) if brand means anything
2013-11-27T00:04:50 < zyp> sure it's not a fake sandisk?
2013-11-27T00:05:09 < zyp> lots of counterfeit memory cards around
2013-11-27T00:05:17 < mattbrejza> yea perhaps
2013-11-27T00:05:21 < mattbrejza> hard to tell i guess
2013-11-27T00:05:29 < fbs> it is

2013-11-27T00:05:56 < mattbrejza> and its only 2GB
2013-11-27T00:06:00 < mattbrejza> although quite old
2013-11-27T00:06:53 < mattbrejza> and is doing a good job of crashing every program that tries to do anyithng with it
2013-11-27T00:07:36 < zyp> fwiw I shot a 6min video clip with my camera earlier today, yielding a 2GB video file on a sandisk memory card
2013-11-27T00:07:51 < zyp> and I'm not concerned by the wear of that at all
2013-11-27T00:08:25 < mattbrejza> yea my concern was with the modifiying the same FAT item every few secs, but if theres wear levelling then i guess it doesnt matter

2013-11-27T02:21:57 < zyp> panels?
2013-11-27T02:22:28 < Thorn> their term for banks I guess
2013-11-27T02:23:15 < zyp> yeah, I guess that means you can still load instructions from one bank while the other bank is erasing/flashing sectors

2013-11-27T18:53:15 < Laurenceb> yet fatfs prints the wrong time
2013-11-27T18:53:26 < Laurenceb> i wonder if its broken rfprintf
2013-11-27T18:53:46 < jpa-> why do you keep using your broken printf :)
2013-11-27T18:54:03 < trepidaciousMBR> printf that prints numbers off by one? That is pretty nasty ;)
2013-11-27T18:56:23 < ouah> I'm looking into my generated hex (from elf through arm-none-eabi-objcopy -O ihex) and I'm very surprised to find a whole block of 0x00 (like hundreds of bytes). Isn't .bss supposed to not be in flash code?
2013-11-27T18:57:12 < fbs> at what address?
2013-11-27T18:57:13 < jpa-> ouah: so check what it belongs to; objdump -D

2013-11-27T18:58:23 < zyp> depends on what it is
2013-11-27T18:58:26 < jpa-> one probable candidate is the unused entries in vector table
2013-11-27T18:58:27 < ouah> jpa-: I mean it shows RAM addresses
2013-11-27T18:58:48 < zyp> a big block of nothing between sections won't show up in disassembly
2013-11-27T18:58:49 < ouah> jpa-: it's is near the end and the vector table is at the beginninng
2013-11-27T18:58:59 < jpa-> zyp: ah, true
2013-11-27T18:59:21 < jpa-> ouah: check the address and then compare to your .map file
2013-11-27T18:59:32 < zyp> ouah, it's ram addrs?
2013-11-27T18:59:40 < ouah> zyp: I think so
2013-11-27T18:59:57 < zyp> then you are picking sections that are going into ram
2013-11-27T19:00:07 < zyp> when generating the hex
2013-11-27T19:00:10 < zyp> don't do that.
2013-11-27T19:00:11 < jpa-> maybe a linker script that programs .bss in ram? i have seen some do that
2013-11-27T19:00:25 < jpa-> pretty silly, of course

2013-11-27T19:01:03 < zyp> that's not what I meant

2013-11-27T19:01:21 < jpa-> ah
2013-11-27T19:01:34 < zyp> ouah, do the opposite approach, only pick the sections you want

2013-11-27T19:14:08 < jpa-> maybe st linker script marks .data as code because they have those funny "ramfuncs" there?

2013-11-27T19:14:37 < jpa-> ah yeah.. silly me.. of course .data is there always anyway
2013-11-27T19:14:46 < Laurenceb> looks like rfprintf is broken
2013-11-27T19:15:07 < Laurenceb> how big is nanolib printf with float?
2013-11-27T19:15:17 < ouah> zyp: I don't think so
2013-11-27T19:15:43 < ouah> zyp: I don't have object that big, it's a concatenation of a lot of objects
2013-11-27T19:15:56 < jpa-> Laurenceb: maybe you just fail in printf format strings ;)
2013-11-27T19:16:01 < zyp> well, I don't know, you won't give me the elf so I can't know :)

2013-11-27T19:16:53 < zyp> no, that has nothing to do with .bss
2013-11-27T19:17:18 < jpa-> ouah: arm-none-eabi-objdump -t foobar.elf | grep ^200 | sort    should give you list of stuff in .data
2013-11-27T19:17:22 < ouah> or zero-initialized objects if you prefer that goes into .data section instead of .bss

2013-11-27T19:17:33 < Laurenceb> nothing about this problem makes sense

2013-11-27T19:43:59 < ouah> zyp: actually I think again about what you said about partly initialized array, and I have usb descriptors in this code, I'm invistigating but it could be well the reasons for the all these extra 0x00 bytes...
2013-11-27T19:44:00 < Laurenceb> unless i'm misinterpretting fat32
2013-11-27T19:48:24 < PaulFertser> Does newlib use DST TZ by default? I'd not expect it to. But it can be made to by setting TZ appropriately and calling tzset(). Anyway 2013-11-27 doesn't belong to DST.
2013-11-27T19:49:36 < Laurenceb> hmf
2013-11-27T19:49:52 < Laurenceb> is fat32 timestamping off by one by default?
2013-11-27T19:50:01 < Laurenceb> windoze seems to be offsetting the time
2013-11-27T19:50:07 < Laurenceb>  what the hell
2013-11-27T19:53:14 < Laurenceb> either windoze or fatf32 has a bug, but windoze is fudging the timestamps according to my linux box
2013-11-27T19:53:27 < Laurenceb> so fat32 needs a fudged timestamp??

2013-11-27T19:58:22 < Laurenceb> or ubuntu has a bug...
2013-11-27T20:01:10 < PaulFertser> Laurenceb: your gdb output says hour 18 and the kernel reports hour 18 for the same file on the same medium, so why do you think a bug is not in your code interpreting that structure you printed?
2013-11-27T20:01:56 < Laurenceb> that was last week
2013-11-27T20:02:01 < Laurenceb> 22nd
2013-11-27T20:02:54 < Laurenceb> its not a printf bug for sure
2013-11-27T20:02:59 < Laurenceb> but other than that...
2013-11-27T20:03:32 < Laurenceb> its weird that times set on my windows machine are offset by an hour
2013-11-27T20:03:38 < Laurenceb> according to ubuntu
2013-11-27T20:03:54 < Laurenceb> thats true with micro SD cards too
2013-11-27T20:04:16 < Laurenceb> on windows everything works correctly
2013-11-27T20:04:51 < Laurenceb> but i look at the timestamps on linux and they are an hour early

2013-11-28T13:18:56 < bighead123> Hello, Bought Chinese LCD FTM320C01Z for 7$ in hope it would work with STM32F4 Discovery, can't find datasheet, pinout description, controller name. nothing found using Google
2013-11-28T13:19:19 < jpa-> great purchase
2013-11-28T13:19:56 < jpa-> can you see the code on the chip that is on the LCD module?
2013-11-28T13:20:43 < bighead123> jpa-: I'll copy now all of info written on lcd
2013-11-28T13:23:33 < bighead123> jpa-: FTM320C01Z-00X    08 10 10       M423A09    MB013     M30112A222    M403A310    FPC-FTM320C01Z-00    2008-05-17   XA0835
2013-11-28T13:24:16 < jpa-> pretty useless, those are specific to the manufacturer of the module and if google gives you nothing, those won't help
2013-11-28T13:24:24 < jpa-> but the controller chip might be a common one
2013-11-28T13:25:00 < bighead123> jpa-: but how to find pinouts?
2013-11-28T13:25:28 < jpa-> did you find which controller chip it is?
2013-11-28T13:26:35 < bighead123> jpa-: I think to remove plastics and most likely there would be something written, controller name
2013-11-28T13:27:01 < jpa-> plastics?
2013-11-28T13:27:22 < jpa-> well, if you find the controller, you can probe to find the pinout of the connector
2013-11-28T13:27:31 < jpa-> but i would just buy a new module with proper specs
2013-11-28T13:28:33 < bighead123> jpa-: delivery from china to here takes 5-6 weeks so I can't wait, this module I bought here in local phone parts store
2013-11-28T13:29:04 < bighead123> jpa-: I bought also another one from china in past and didn't got it working also
2013-11-28T13:29:37 < bighead123> jpa-: so I would now do everything to make any LCD work
2013-11-28T13:29:57 < jpa-> so buy from farnell/mouser/digikey with next day delivery
2013-11-28T13:32:27 < bighead123> jpa-: There are not TFT lcds with integrated framebuffer ram and with resolution at least 240x320, all of them have parallel 16-24bit interface with Vsync/Hsync and without GRAM
2013-11-28T13:32:48 < bighead123> jpa-: have you bought such LCD there?

2013-11-28T13:40:56 < bighead123> jpa-: thank you, Newhavendisplay is great for 16$, heh, 32 € costs entire resign I am making :-D
2013-11-28T13:48:00 < dongs> um
2013-11-28T13:48:07 < dongs> newhavendisplay is a fucking ripoff
2013-11-28T13:48:52 < bighead123> dongs: Why?
2013-11-28T13:51:03 < bighead123> dongs: I had one  482x272 LCD from NHD and it worked great with i.MX53 QSB, also few 2x16 LCDs bought from their "Special offers" and they are still working
2013-11-28T13:51:19 < dongs> well im sure tehy work
2013-11-28T13:51:31 < dongs> but 2x16 CLCD with backlight from chinks is like <$2/ea
2013-11-28T13:51:40 < dongs> and newhaven TFT shit is also overpriced.
2013-11-28T13:52:18 < bighead123> dongs: yes, I know, just bought all of them together because of faster delivery
2013-11-28T13:54:34 < bighead123> dongs: that time 2x16 lcds were in "Special Offers" for 6$ and TFTs for 10$, however that tfts were needed for three 24v/5v/3.3v voltages to be connected.

2013-11-28T14:30:13 < fbs> murderer
2013-11-28T14:30:15 < Laurenceb> turns out it was a 10µF 0603 cap

2013-11-28T14:30:22 < Laurenceb> next to it
2013-11-28T14:30:25 < Steffanx> lol?
2013-11-28T14:30:38 < Laurenceb> the board place had hand soldered it after reflow failed
2013-11-28T14:30:49 < Laurenceb> looks like they damaged one end
2013-11-28T14:31:41 < Laurenceb> looks like large MLCC stuff is easy to break
2013-11-28T14:32:44 < Steffanx> Just curious Laurenceb, iirc you said once you have some money issues. Is all this you do not paid as in a normal salary?
2013-11-28T14:33:03 < Laurenceb> hehe
2013-11-28T14:33:16 < Laurenceb> atm im officially unemployed
2013-11-28T14:33:41 < Steffanx> And still you work so 'hard' on this. You're too good for this world :P
2013-11-28T14:33:46 < Laurenceb> heh
2013-11-28T14:33:57 < Laurenceb> i should be able to organise some grants soon
2013-11-28T14:36:55 < bighead123> Thorn: Thank You, great, until this my only source was Aliexpress/Alibaba. :)
2013-11-28T14:37:27 < Thorn> they're on aliexpress but assortment and prices are lousy
2013-11-28T14:37:37 < Thorn> direct is much better
2013-11-28T14:37:43 < bighead123> Thorn: yes :)
2013-11-28T15:00:45 < karlp> if I feed a constant value into a bandpass filter, (like the armbiquad stuff) I should get 0 out right?
2013-11-28T15:00:52 < karlp> I'm getting -1 constant out, which seems... odd.
2013-11-28T15:01:01  * karlp needs to go run some test value off line
2013-11-28T15:01:08 < Robint91> karlp, fixed point? or float

2013-11-28T21:19:33 < Steffanx> the demo is still a bit disappointing imho
2013-11-28T21:19:47 < TitanMKD> ha yes it is very basic
2013-11-28T21:19:56 < Steffanx> yes, but i mean its slow

2013-11-28T21:20:34 < TitanMKD> 64millions of pixels/s is slow ?
2013-11-28T21:21:15 < TitanMKD> ha maybe the other stuff like image viewer or video player mjpeg ... but all is not optimized at all ...

2013-11-28T21:29:24 < TitanMKD> i saw a demo on a big screen and it is very impressive
2013-11-28T21:36:13 < Thorn> what was that, some expensive demo kit or a custom design?
2013-11-28T21:39:03 < TitanMKD> an expensive demo kit
2013-11-28T21:39:16 < TitanMKD> showing a demo of embedded java
2013-11-28T21:39:24 < Steffanx> stm32j .. yay
2013-11-28T21:39:54 <+dekar> ...nay -.-
2013-11-28T21:40:00 < TitanMKD> anyway with the horse power behind + the DMA feature it is amazing fast
2013-11-28T21:43:38 <+dekar> one can even do pretty PWM using an F4 ;) https://dl.dropboxusercontent.com/u/28467113/pwm.mp4
2013-11-28T21:44:10 < Steffanx> Yeah..
2013-11-28T21:44:19 < Steffanx> inspired by macmini :P
2013-11-28T21:44:45 <+dekar> actually... appletv :P
2013-11-28T21:45:25 < Steffanx> oh :D
2013-11-28T21:46:23 < TitanMKD> hehe an F4 just to drive a PWM it is a bit overkill ;)
2013-11-28T21:46:54 <+dekar> Steffanx, I actually don't even know since I didn't design the case, but I like having the last word in an argument :P

2013-11-28T21:50:14 < TitanMKD> i modified the demo to compute it ;)
2013-11-28T21:50:26 <+dekar> It's just a prototype, it will be brushed aluminium with more even lighting.
2013-11-28T21:50:43 <+dekar> We were EMI testing it last week and actually setting the GPIO speed to 100mhz while driving the LEDs at 600khz made it fail. :/
2013-11-28T21:52:20 <+dekar> But lowering the rise times did the job :)

2013-11-28T21:56:26 < gxti> less drive current = less emitted noise
2013-11-28T21:57:32 < Thorn> to me, low rise time == fast rise time

2013-11-28T22:53:13 < jpa-> work in progress to become a proper fail?

2013-11-28T22:53:35 < Laurenceb_> ah
2013-11-28T22:53:43 < Laurenceb_> is that a hammond enclosure?
2013-11-28T22:53:50 < gxti> polycase
2013-11-28T22:53:54 < TitanMKD> gxti: an STM32F107 ?
2013-11-28T22:54:04 < gxti> f103
2013-11-28T22:54:06 < jpa-> why would someone want to attach BMP with screws? :D
2013-11-28T22:54:18 < gxti> because it's a Real Pro Tool like keil craps
2013-11-28T22:54:35 < gxti> there's a version without the mounting tabs but maybe someone is dumb enough to use this in production
2013-11-28T22:54:56 < TitanMKD> it is a logici analyzer or something similar ?
2013-11-28T22:55:04 < jpa-> black magic probe
2013-11-28T22:55:08 < fbs> isolated
2013-11-28T22:55:16 < gxti> fbs wins the prize
2013-11-28T22:55:17 < Laurenceb_> "polycase" ??
2013-11-28T22:55:22 < Laurenceb_> where from?
2013-11-28T22:55:26 < gxti> polycase.com
2013-11-28T22:55:27 < jpa-> gxti: of course there is a ##stm32 discount, right?
2013-11-28T22:55:39 < fbs> do you use those ad<something> isolators?
2013-11-28T22:56:04 < TitanMKD> it is optoisolation ?
2013-11-28T22:56:10 < gxti> no, they're silicon labs SI864x
2013-11-28T22:56:25 < gxti> TitanMKD: yes, well technically it's not 'opto' so much as 'radio' but they are galvanically isolated
2013-11-28T22:56:33 < gxti> bits go in, bits come out
2013-11-28T22:56:44 < gxti> amps don't go in or out.
2013-11-28T22:56:47 < jpa-> capacitive isolation?
2013-11-28T22:56:56 < gxti> something like that
2013-11-28T22:56:57 < TitanMKD> not bad up to 5KV isolation ;)
2013-11-28T22:57:06 < fbs> got some adums here
2013-11-28T22:57:10 < gxti> wacky dielectric shit
2013-11-28T22:57:16 < gxti> point is they go fast and don't cost much
2013-11-28T22:58:12 < gxti> any comments on the form factor? maybe fullsize usb B instead of mini?
2013-11-28T22:58:26 < fbs> do both

2013-11-28T23:01:06 < gxti> cut a slot in the end so you can plug in your ribbon cable then put the lid back on
2013-11-28T23:01:21 < gxti> or use it without the lid if you just have jumper wires or whatever
2013-11-28T23:02:03 < fbs> cant you use a angled header on the edge?

2013-11-28T23:03:33 < fbs> are you going to sell them, or just a personal board?
2013-11-28T23:03:40 < gxti> sell, eventually
2013-11-28T23:03:55 < gxti> no idea on price yet
2013-11-28T23:04:24 < gxti> probably 30-40USD

2013-11-29T00:28:44 < Thorn> I wonder where R2COM is right now
2013-11-29T00:29:47 < Laurenceb_> use chrome?
2013-11-29T00:29:56 < Laurenceb_> lasts 10s in firefox

2013-11-29T04:34:27 < emeb> something that didn't need to be done: http://hackaday.com/2013/11/27/interview-with-damien-george-creator-of-the-micro-python-project/
2013-11-29T04:36:14 < dongs> worthless
2013-11-29T04:36:33 < GargantuaSauce> but python is the most flexible and human-readable programming language!
2013-11-29T04:36:39 < dongs> http://www.kickstarter.com/projects/1883701526/matchboxarm/comments
2013-11-29T04:36:45 < dongs> python is about as write-only as it gets
2013-11-29T04:36:53 < dongs> maybe close matched by ruby
2013-11-29T04:38:08 < zyp> that's ok, I find that python stuff tends to work on first attempt, so there is no need to read them later anyway
2013-11-29T04:40:01 < dongs> hey zyp
2013-11-29T04:40:04 < dongs> done anything with bladerf yet?
2013-11-29T04:42:00 < emeb> especially like how he completely re-wrote the python interpreter for use on the embedded ARM.
2013-11-29T04:42:13 < dongs> what a waste
2013-11-29T04:42:20 < gxti> as a fulltime python developer i agree
2013-11-29T04:43:04 < emeb> hopefully it's bug-compatible with mainline python
2013-11-29T04:44:00 < dongs> http://www.kickstarter.com/projects/swiftnav/piksi-the-rtk-gps-receiver/posts
2013-11-29T04:44:14 < dongs> stalling with a purpose?
2013-11-29T04:44:20 < dongs> Unfortunately we are still not able to fulfil the developer RTK kits as we are still waiting on the radios and the cable assemblies to connect the radios to the Piksis. Its now looking like the cable assemblies are going to have another two weeks or so lead time.
2013-11-29T04:44:28 < dongs> could it be because RTK doesn't actualyl work!@?#
2013-11-29T04:47:55 < zyp> dongs, I was dicking around with it a couple of days ago
2013-11-29T04:48:18 < zyp> http://bin.jvnv.net/f/E77pJ.png <- picking up wlan and shit
2013-11-29T04:49:20 < dongs> opensauces
2013-11-29T04:49:40 < zyp> and then I tried tuning an analog tv signal
2013-11-29T04:49:49 < dongs> you still have analog tv there?
2013-11-29T04:50:08 < zyp> nah, hooked it up to a vcr actually :p
2013-11-29T04:50:13 < dongs> heh
2013-11-29T04:50:20 < dongs> so like ch3/4 thing?
2013-11-29T04:50:21 < dongs> rf modulator?
2013-11-29T04:50:25 < zyp> yeah
2013-11-29T04:50:40 < zyp> european equivalent of that
2013-11-29T04:51:21 < zyp> managed to demodulate the audio from it, but I still have to figure out how to get the video

2013-11-29T04:51:37 < dongs> wasnt it 40?

2013-11-29T04:52:29 < emeb> yeah - I'd like something that went from 1MHz - 500MHz
2013-11-29T04:53:02 < zyp> I like that it can do 2.4G

2013-11-29T04:55:32 < emeb> 17 cents/each for serial flash in 6k qty?
2013-11-29T04:57:04 < dongs> they just wanna get rid of it, so probly 17c even if its not 6k
2013-11-29T04:57:12 < dongs> only 4mbit thjo
2013-11-29T04:57:20 < dongs> if it was 16 i'd buy some

2013-11-29T04:59:59 < englishman> kha suggested an external flash for the radio shits, is there a reason for that vs writing a page at the end of the st?
2013-11-29T05:00:12 < dongs> none
2013-11-29T05:00:18 < dongs> just the fact that theres a lot more of it for cheap
2013-11-29T05:00:28 < dongs> but i cant imagine how much writing youre gonna do on a rx/tx

2013-11-29T05:00:45 < dongs> gxti: horrible USB socket
2013-11-29T05:00:57 < gxti> considering swapping that out yeah
2013-11-29T05:01:12 < dongs> either go for DIP mini or micro
2013-11-29T05:01:17 < dongs> but full-smt micro = a i d s
2013-11-29T05:02:05 < gxti> using either the pth mini or maybe just a full B because they're less annoying to solder
2013-11-29T05:02:57 < zyp> I'd say pth is more annoying to solder than something you just reflow
2013-11-29T05:03:32 < gxti> that is correct, however pure smt connectors break
2013-11-29T05:03:57 < dongs> the micro im using is dip but its reflowing
2013-11-29T05:04:19 < dongs> zyp has the part# somewehre
2013-11-29T05:04:23 < dongs> some FCI part
2013-11-29T05:04:24 < gxti> could use the half-smt ones but i already have a bag of the pth minis

2013-11-30T20:33:31 < dongs>                quickly??
2013-11-30T20:33:42 < dongs> some guy messaged me asking to build him a 500 asic buttcoin miner
2013-11-30T20:34:21 < dongs> http://bitmine.ch/?page_id=863 check this shit lol
2013-11-30T20:34:25 < dongs> 30A @ 0.65V
2013-11-30T20:40:18 < MrMobius> I have been listening to a podcast called soldersmoke.
2013-11-30T20:40:45 < MrMobius> He said he hooked up his arduino to too much voltage and it didnt work right. one chip got too hot so he desoldered it. now its fixed!
2013-11-30T20:40:56 < dongs> hot
2013-11-30T20:41:47 < MrMobius> hot to the touch. that must have been what was causing problems. so he took that chip off.
2013-11-30T20:42:22 < MrMobius> but you can just tear that random chip off and that will fix it.
2013-11-30T20:47:55 < jpa-> normally i would guess it was an overvoltage protection diode that had shorted out; but an arduino probably wouldn't have any such protection diodes
