2015-07-01T04:22:13 < kakimir_> now its sensational documents for the masses

2015-07-01T04:23:01 < dongs> so kukman, waht stm32 projects have you done lately
2015-07-01T04:23:06 < dongs> other than trolling this channel
2015-07-01T04:24:34 < kakimir_> not many

2015-07-01T04:39:17 < dongs> looks like diodes and caps
2015-07-01T04:39:26 < dongs> what are those fucking vertical plates
2015-07-01T04:39:41 < upgrdman> resistors
2015-07-01T04:39:53 < upgrdman> voltage divider for feedback
2015-07-01T04:41:23 < upgrdman> R2COM, found this at work today: http://www.farrellf.com/temp/voltage_multiplier.jpg
2015-07-01T04:53:44 < kakimir_> how many volt diodes it has?
2015-07-01T04:55:36 < upgrdman> i couldnt find the paperwork for it, but it's about the right size to match some of our 400kV systems
2015-07-01T04:56:07 < kakimir_> our?
2015-07-01T04:57:03 < dongs> whats a nigga gona do with 400kV
2015-07-01T04:57:33 < kakimir_> yes. what?
2015-07-01T04:57:35 < dongs> https://www.youtube.com/watch?v=bv_P-54lzDc maybe you can make a new version of this
2015-07-01T04:59:05 < Roklobsta> it could bootstrap another device somehow.  400kV seems a bit much though - I can't imagine what.
2015-07-01T04:59:26 < upgrdman> kakimir_, dongs: x-ray generators
2015-07-01T04:59:54 < kakimir_> samsung did me right in my ass with their new phone
2015-07-01T04:59:57 < dongs> pretty sure my xray is something like 30kV
2015-07-01T05:00:03 < upgrdman> dongs, lol
2015-07-01T05:00:13 < dongs> i'd have to look at hte shit and im too lazy
2015-07-01T05:00:15 < upgrdman> dongs, medical is often 50 - 120kV
2015-07-01T05:00:15 < kakimir_> no more samsuck
2015-07-01T05:00:17 < upgrdman> BUT
2015-07-01T05:00:49 < upgrdman> xraying a shipping container? fuck that. 300 - 750kV is common
2015-07-01T05:00:57 < kakimir_> https://drive.google.com/folderview?id=0B2GcdpJiNGfKUEF5QVhzcFZsTFE&usp=sharing i have never fired it up
2015-07-01T05:01:04 < upgrdman> better penetration (that's what she said)

2015-07-01T05:08:34 < Roklobsta> dongs: the strips could be some kind of overvoltage flashover protection.
2015-07-01T05:09:55 < Roklobsta> it'd possibly be copper fingers - one side on the primary and one side on ground seperated by a few mm - enough to arc if there was too much voltage in a stage.
2015-07-01T05:09:59 < upgrdman> <upgrdman> voltage divider for feedback
2015-07-01T05:10:19 < Roklobsta> ah
2015-07-01T05:10:49 < Roklobsta> i have seen that arcing fingers protection in power supplies
2015-07-01T05:11:20 < Roklobsta> upgrdman: just some 0603's on phenolic paper.
2015-07-01T05:11:21 < kakimir_> voltae divider?
2015-07-01T05:11:35 < upgrdman> yes
2015-07-01T05:11:39 < upgrdman> for feedback
2015-07-01T05:11:50 < upgrdman> because you want to know the fucking voltage
2015-07-01T05:12:06 < Roklobsta> aren't those ladders open ended with no feedback generally?
2015-07-01T05:12:11 < kakimir_> multiplier isns't it?
2015-07-01T05:12:18 < kakimir_> isn't
2015-07-01T05:12:28 < upgrdman> kakimir_, yes but losses are not costant
2015-07-01T05:12:49 < upgrdman> Roklobsta, can be. but not for xray usage. you want control over it.
2015-07-01T05:14:16 < Roklobsta> pah, you can make xrays just peeling sticky tape.
2015-07-01T05:14:58 < upgrdman> but if you want to make systems that big corps and govs will buy, you need fine control over your xray generation
2015-07-01T05:15:16 < upgrdman> NDT, security screening, medical...
2015-07-01T05:15:23 < Roklobsta> just sell a lot of sticky tape at inflated prices to the military.
2015-07-01T05:15:35 < kakimir_> https://www.youtube.com/watch?v=J_8mdH20qTQ hah :)
2015-07-01T05:15:38 < upgrdman> and a chinaman to peel it
2015-07-01T05:16:56 < upgrdman> kakimir_, why havnt you fired up your crotchcraft-walton multiplier?
2015-07-01T05:17:52 < Roklobsta> huh huh you said crotch huh
2015-07-01T05:18:14 < upgrdman> im so naughty
2015-07-01T05:18:43 < kakimir_> upgrdman: I'm lazy, busy and tired
2015-07-01T05:18:52 < kakimir_> and I don't have use for it atm.
2015-07-01T05:18:54 < upgrdman> understandable
2015-07-01T05:21:12 < upgrdman> just stick it in one of those usb power banks, and offer it to someone that needs to charge their phone
2015-07-01T05:22:02 < Roklobsta> it might be good for an electric fence
2015-07-01T05:22:18 < Roklobsta> just stick a big resistor on the output
2015-07-01T05:24:04 < kakimir_> talking of usb I was sittin in toilet havin dump and took photo of this
2015-07-01T05:24:46 < upgrdman> WHY DOES SOMEBODY NOT KNOW HOW TO FLUSH THE TOILET AFTER THEY'VE HAD A SHIT??!!?!?!?! DISGUSTING!!!!
2015-07-01T05:24:59 < upgrdman> that video. much lol. very wow.

2015-07-01T06:05:48 < upgrdman> why they prohibit stm

2015-07-01T11:19:58 < pointertonullval> Hey guys, I'm working on a project that involves the STM32F407 micro (Discovery board at the moment). But I'm having a problem with USB Host: basically if I plug and unplug quickly and repeatedly the USB pen, after not so much it stops to mount the usb. I'm using the USB_Host_Library from STMicroelectronics. Has anyone of you an idea of why? Thanks in advance
2015-07-01T11:20:43 < zyp> sounds like a race condition or something
2015-07-01T11:20:53 < dongs> failcondition in shtity ST code
2015-07-01T11:20:58 < zyp> or maybe the host just finds the device unreliable and gives up
2015-07-01T11:21:14 < zyp> you're not supposed to unplug shit rapidly
2015-07-01T11:21:22 < scrts2> shtit code!
2015-07-01T11:21:38 < scrts2> it's shit and tit together

2015-07-01T11:27:33 < zyp> no, I don't mean a deadlock, I mean a race having unintended consequences in the code
2015-07-01T11:27:59 < zyp> like reenabling an interrupt before it's disabled, leaving it disabled forever afterwards
2015-07-01T11:28:07 < zyp> or something like that

2015-07-01T13:00:26 < dongs> With Zano due to be shipping this month (July), I'm finding it rather concerning that we are still yet to see the following:
2015-07-01T13:00:29 < dongs> - Collision Detection during real flight (not the tennis demo...they had to move their hands to avoid a collision). - Autonomous Flight (circling around target, follow me at specified angle, 'Return to Home'. - Onboard Video Footage (raw, not stabilised nor passed through HPC as I won't be using that facility anyway).
2015-07-01T13:00:35 < dongs> haha
2015-07-01T13:00:39 < dongs> At this time, I'm considering requesting a refund in the next few weeks, I would assume that others will too UNLESS Zano break this silence and start being honest, transparent and open with their loyal consumers, the consumers that have made this project possible. There is no excuse, it takes minutes to post a Facebook Status or Kickstarter Update to simply let us know what is going on.
2015-07-01T13:00:45 < dongs> its slowly beginning
2015-07-01T13:02:01 < jpa-> it would be interesting to see the backers only update

2015-07-01T15:31:45 < dongs> I made my own investigations, and have had my own dialogue through the process of backing this project. So I am very assured on my own behalf that I will get a nano drone that I am very happy with - in fact I have been so convinced of that, that I backed for four Zanos.

However, let's all take into account, once we have shipped ZANO to our 15,000 (approx.) pre-orders and backers (Starting July-end), there will be content created from ZANO from all 4 corners of the globe, available online! What an amazing thought?

2015-07-01T15:39:02 < Laurenceb_> I can find the name of the library from the parts, but how can i find the file path?
2015-07-01T15:39:09 < dongs> How about an invite up to your HQ (I am just over the bridge in Bristol), let me play with a Zano, film the experience and post the video (following your approval) myself? If I'm unimpressed, we part ways with a refund and I say no more.

In less time then it took you to write this response you could have posted a raw clip with no editing so people can assess the quality of the camera.

2015-07-01T16:06:00 < dongs>  I have seen other posts indicating we would be "flooded" with photos and videos. Before I get flamed for this, I want to reiterate how highly I hold the Torquing team, and that this has been the best project I have participated in. But still very disappointed that they haven't lived up to the expectations that they have set with us.

2015-07-01T22:18:02 < upgrdman_> a TVD diode is basically a zener diode that can handle short periods of extreme overload, right?
2015-07-01T22:18:28 < upgrdman_> is there a benefit to used a zener to ground, versus a diode to ground and a giode to VDD?

2015-07-01T22:42:50 < jon1012_> someone managed to get the new stm32f7 discovery board working on linux ?
2015-07-01T22:50:24 < Fleck> hmm, whats the problem jon1012?
2015-07-01T23:04:28 < jon1012_> Fleck, no problem, just want to know if there are some examples out there
2015-07-01T23:04:38 < jon1012_> Fleck, I have no official IDE, so no system files and such
2015-07-01T23:04:47 < Fleck> you need template?
2015-07-01T23:04:50 < Fleck> for gcc?
2015-07-01T23:07:31 < jon1012_> yeah
2015-07-01T23:07:44 < jon1012_> I have one that works on stm32f4
2015-07-01T23:07:57 < jon1012_> (stm32f407)
2015-07-01T23:08:13 < jon1012_> but haven't had any luck making it work on stm32f417, so haven't even tried for stm32f7 yet

2015-07-02T03:17:42 < dongs> emeb: err
2015-07-02T03:17:48 < dongs> i thought encoder increments by 2
2015-07-02T03:17:55 < dongs> thats the point
2015-07-02T03:17:59 < dongs> half-click is 1, full click is 2
2015-07-02T03:18:10 < dongs> thats what all the ones I used did
2015-07-02T03:19:14 < emeb> dongs: right - 2 is normal, but sometimes it goes by 1. contact bounce or something. unreliable.
2015-07-02T03:19:33 < dongs> was there TIF/something for the input filter?
2015-07-02T03:19:38 < dongs> i seem to recall
2015-07-02T03:19:43 < dongs> duno if its applicable to encoder mode
2015-07-02T03:20:05 < emeb> Filters should work in encoder mode - I've got input filters set up. Doesn't seem to help.

2015-07-02T10:35:20 < Roklobsta> anyone got some good ideas on making gcc use more registers?
2015-07-02T10:35:52 < dongs> yes dont use gcc
2015-07-02T10:36:25 < Roklobsta> pah
2015-07-02T10:36:27 < Roklobsta> ok
2015-07-02T10:36:38 < Roklobsta> are the commercial ones any better, really?
2015-07-02T10:36:58 < specing> dongs recommends zanocc (tm)
2015-07-02T10:37:07 < dongs> by far
2015-07-02T10:37:15 < dongs> try the 32k limited armcc
2015-07-02T10:37:20 < Roklobsta> ok thanks
2015-07-02T10:37:23 < dongs> compare its output to gcc
2015-07-02T10:37:26 < Roklobsta> yep
2015-07-02T10:37:29 < dongs> you'll be amazed
2015-07-02T10:37:37 < scummos> note though that dongs hates anything which doesn't cost money so he might be a bit biased
2015-07-02T10:37:42 < specing> armcc probably has one very big flaw
2015-07-02T10:37:49 < specing> doesen't support Ada/SPARK
2015-07-02T10:37:58 < dongs> doesnt support shit/thatdoesntamtter
2015-07-02T10:38:11 < Roklobsta> specing: are you going down the Ada rabbit hole?
2015-07-02T10:38:16 < specing> Roklobsta: oh yes
2015-07-02T10:38:42 < Roklobsta> worth the effort? i did do ada at uni in the early 90's until everyone dropped it in favour of java/c++
2015-07-02T10:39:05 < specing> I don't know, I am kind of dissapointed at c/c++
2015-07-02T10:39:14 < specing> and java is simply a no-go on embedded
2015-07-02T10:39:52 < Roklobsta> i have some simple code and gcc even at O2 has really done a messy job
2015-07-02T10:44:12 < specing> *shrug*
2015-07-02T10:45:46 < Roklobsta> specing: how complex an Ada application have you made on the stm32?
2015-07-02T10:46:19 < specing> haven't made any because I was setting up toolchain when real life caught on me
2015-07-02T10:47:03 < specing> AdaCore has a proven tetris demo for stm32 though
2015-07-02T10:54:53 < Roklobsta> specing: aha.  Real Life.  I know what you mean.

2015-07-02T11:22:39 < ehsanv> i need to build a gui (on a 7" lcd + resistive touch), i tried to code it all but changes made through project will cost alot of time to edit code. is emWin good? and is it support custom lcd's? (interface, change ports for lcd interface, etc )
2015-07-02T11:23:36 < ehsanv> if there's another free alternate for emWin that's good
2015-07-02T11:26:06 < dongs> emwin wokrs pretty good
2015-07-02T11:26:10 < dongs> also uc/GUI
2015-07-02T11:26:19 < dongs> you can pirate both from chinese stm32  board vendors.
2015-07-02T11:27:08 < ehsanv> dongs: lol, but st release emwin library binaries freely for stm users?!
2015-07-02T11:27:16 < dongs> oh, that works
2015-07-02T11:27:17 < dongs> tehn use it
2015-07-02T11:28:34 < ehsanv> dongs: and can i write my own functions for accessing lcd/touch? i don't want to spend time on reading and working with it and then i find out i can't use it with my hardware
2015-07-02T11:28:48 < dongs> of course you can, its not hardware specific
2015-07-02T11:28:55 < dongs> as far as I remember you just give it a framebuffer
2015-07-02T11:28:56 < ehsanv> dongs: thanks man ;)
2015-07-02T11:29:02 < dongs> and then have your own way to dump it to lcd
2015-07-02T11:29:06 < dongs> i tihnk i used emwin with a SPI color lCD
2015-07-02T11:29:10 < dongs> been a few years
2015-07-02T11:29:40 < ehsanv> dongs: i'm using lcd in just a year and half
2015-07-02T11:29:52 < ehsanv> dongs: newbie in arm actually
2015-07-02T11:29:53 < ehsanv> lol
2015-07-02T11:30:57 < Fleck> ehsanv: also check ugfx.org
2015-07-02T11:32:49 < dongs> rerr no
2015-07-02T11:33:21 < dongs> that shit is not even FREE
2015-07-02T11:35:37 < ehsanv> Fleck, thanks but it's not free for commercial products,
2015-07-02T11:38:07 < Fleck> seggers emWin is?
2015-07-02T11:38:22 < ehsanv> Fleck: it's released by st
2015-07-02T11:38:38 < ehsanv> Fleck: only library binaries
2015-07-02T11:39:00 < Fleck> ohh, that lib
2015-07-02T11:39:19 < ehsanv> yeah ;)
2015-07-02T11:39:45 < ehsanv> but thanks, i take a deeper look at both,

2015-07-02T16:40:58 < jadew> they always find something to fix so the nvidia drivers stop working
2015-07-02T16:41:25 < Laurenceb> whats the size of that jpg ?
2015-07-02T16:42:00 < jadew> 5312 × 2988 pixels
2015-07-02T16:42:06 < Laurenceb> ah no wonder
2015-07-02T16:42:07 < qyx_> 5,312px × 2,988px (scaled to 1,280px × 720px)
2015-07-02T16:42:15 < Laurenceb> large jpegs cause issues
2015-07-02T16:42:18 < qyx_> medium sized image
2015-07-02T16:42:37 < Laurenceb> probably some memory allocation fail
2015-07-02T16:44:03 < jadew> Laurenceb, what browser?
2015-07-02T16:44:43 < Laurenceb> firefox
2015-07-02T16:44:54 < jadew> does it happen with chrome too?
2015-07-02T16:45:00 < Laurenceb> lol risky
2015-07-02T16:45:05 < jadew> heh
2015-07-02T16:45:28 < Laurenceb> yeah works fine
2015-07-02T16:45:43 < Laurenceb> whyy
2015-07-02T16:45:52 < jadew> well, it shouldn't happen at all
2015-07-02T16:45:58 < Laurenceb> theres about 100 times more pixels than the resolution
2015-07-02T16:46:01 < Laurenceb> of the lens
2015-07-02T16:46:18 < jadew> but at least now you know that something in FF calls some API or talks to some driver that screwes up really bad
2015-07-02T16:46:31 < Laurenceb> yeah
2015-07-02T16:47:54 < _Sync_> well
2015-07-02T16:47:56 < _Sync_> > 2015
2015-07-02T16:47:58 < _Sync_> > using firefox
2015-07-02T16:48:13 < jadew> what else?
2015-07-02T16:48:47 < jadew> it started
2015-07-02T16:50:00 < jadew> I'd use chrome if the tabs worked
2015-07-02T16:50:26 < _Sync_> they work for me
2015-07-02T16:50:49 < jadew> yeah, I tend to open more than 4 tabs
2015-07-02T16:51:04 < _Sync_> I currently have around 200 tabs open in chromium

2015-07-02T16:53:25 < jadew> pointertonullval, that's unrelated to ram
2015-07-02T16:54:02 < jadew> I really wonder why they don't fix it
2015-07-02T16:54:11 < jadew> people have been crying about it for years
2015-07-02T16:54:18 < pointertonullval> _Sync_, jadew I didn't read what the bug was
2015-07-02T16:54:25 < jadew> it's not like they don't have a good example on how it can be done
2015-07-02T16:54:41 < jadew> pointertonullval, it's in the caption bar :P
2015-07-02T16:54:52 < _Sync_> I don't like the firefox way either

2015-07-02T16:55:14 < jadew> it's much better than infinitely shrinking tabs
2015-07-02T16:55:30 < pointertonullval> jadew, yeah I hate chrome tab management too
2015-07-02T16:55:31 < _Sync_> but the reason I use chromium is that it doesn't get sluggish when running forever with shitloads of tabs
2015-07-02T16:55:51 < jadew> _Sync_, it's why it pisses me off so bad
2015-07-02T16:55:55 < jadew> I want to use Chrome/chromium too
2015-07-02T16:56:04 < jadew> it does a lot of things better than chrome
2015-07-02T16:56:10 < jadew> *better than FF
2015-07-02T16:56:32 < jadew> but I'm used to opening hundreds of tabs and that just doesn't go well with chrome
2015-07-02T16:56:44 < _Sync_> I'm used to small icons
2015-07-02T16:56:55 < jadew> what if it's the same icon?
2015-07-02T16:56:56 < _Sync_> I usually just open a new window when they get too small
2015-07-02T16:57:11 < _Sync_> I can usually remember which one I want
2015-07-02T16:57:15 < jadew> I can't even imagine watching porn like that
2015-07-02T16:58:21 < pointertonullval> Guys does anyone of you use OSX for stm32 firmware development? I need to use OSX for iOS development and I would like to use the same OS for the stm32.. Thansk!
2015-07-02T16:58:53 < jadew> some people here might
2015-07-02T16:59:03 < _Sync_> but thank god ram is not an issue anymore, before that it was really annpying to browse
2015-07-02T16:59:15 < jadew> _Sync_, yeah
2015-07-02T16:59:36 < jadew> luckly web developers have become more lazy and more stupid and they're catching up
2015-07-02T16:59:54 < _Sync_> well
2015-07-02T17:00:04 < _Sync_> they still are limited by their shitty ultrabooks housing 8G
2015-07-02T17:00:10 < jadew> thanks to all jQuery & co, the shitty browsing experience is brought back into our homes!
2015-07-02T17:00:25 < _Sync_> so I got some time to spare with 64G in the machine currently

2015-07-02T17:01:19 < _Sync_> depends on what I do
2015-07-02T17:01:30 < _Sync_> when I'm compiling it can go up to around 40G
2015-07-02T17:01:45 < jadew> wth are you compiling?
2015-07-02T17:01:54 < jadew> windows?
2015-07-02T17:01:55 < _Sync_> lots of threads with template shit
2015-07-02T17:02:06 < jadew> ah, yeah
2015-07-02T17:02:13 < dongs> C++ and gaycc
2015-07-02T17:02:24 < jadew> speaking of g++
2015-07-02T17:02:34 < jadew> remember how I made that wxWidgets program?
2015-07-02T17:02:38 < _Sync_> msDUMcc is not better
2015-07-02T17:02:49 < jadew> g++ generates a 6 Mb executable after stripping
2015-07-02T17:02:58 < jadew> VC, generates a 3 Mb one
2015-07-02T17:03:05 < dongs> lunix
2015-07-02T17:03:06 < jadew> and does it A LOT faster
2015-07-02T17:03:26 < jadew> the difference is like... 40 seconds vs 3
2015-07-02T17:03:37 < _Sync_> wat
2015-07-02T17:03:42 < _Sync_> something is wrong then
2015-07-02T17:03:55 < jadew> I switched from codelite to VS just because of that, every time I was starting debugging I had to wait for the linker
2015-07-02T17:04:11 < _Sync_> or slowass machine
2015-07-02T17:04:16 < jadew> _Sync_, same machine

2015-07-02T17:04:25 < _Sync_> strange
2015-07-02T17:04:26 < dongs> do you have 32gb ram
2015-07-02T17:04:31 < jadew> 16 Gb of ram
2015-07-02T17:04:33 < dongs> or like 4

2015-07-02T17:04:41 < jadew> should be enough
2015-07-02T17:04:48 < englishman> lunix doesnt need more than 512k memory
2015-07-02T17:04:53 < englishman> everything more than that is bloat
2015-07-02T17:04:58 < jadew> lol

2015-07-02T17:09:04 < jadew> pointertonullval, why is your OS in italian?
2015-07-02T17:09:29 < pointertonullval> jadew, because is the work pc
2015-07-02T17:09:36 < Rickta59> there are some people using that stm32duino port using osx

2015-07-02T17:10:41 < jadew> pointertonullval, why don't you use a real OS tho?
2015-07-02T17:10:42 < pointertonullval> superbia, nope I need it for iOS development
2015-07-02T17:10:50 < jadew> oh

2015-07-02T17:10:55 < dongs> er wat

2015-07-02T17:11:37 < jadew> where did you get that from?
2015-07-02T17:12:05 < dongs> that was a question
2015-07-02T17:12:16 < jadew> the italian remark was about his task manager screenshot
2015-07-02T17:12:30 < pointertonullval> Yeah basically you can't compile or actually deploy iOS apps from others operating system
2015-07-02T17:12:51 < jadew> yeah, I have a mac too, just for that
2015-07-02T17:12:55 < pointertonullval> Oh yes the task manager is on windows
2015-07-02T17:12:55 < jadew> never used it
2015-07-02T17:13:06 < jadew> it's a mac mini
2015-07-02T17:13:44 < jadew> had it for 4-5 years already
2015-07-02T17:13:58 < pointertonullval> jadew, still fine
2015-07-02T17:14:34 < jadew> yeah, I'm considering wiping out the OS and making it a SVN server
2015-07-02T17:14:46 < dongs> you mean shithub server
2015-07-02T17:14:51 < dongs> who the fuck uses svn in 2015
2015-07-02T17:15:03 < jadew> I still do
2015-07-02T17:15:33 < pointertonullval> svn? blahh
2015-07-02T17:16:03 < pointertonullval> go for git

2015-07-02T17:17:02 < jadew> I wonder what's going to be next
2015-07-02T17:19:04 < pointertonullval> I guess git will be here for a lot
2015-07-02T17:19:52 < jadew> that's what I used to think about CVS, then SVN came around

2015-07-02T18:07:22 < Tectu> just received an STM32F7 discovery board. Pretty neat board. 1000 times better than what they did with the STM32F429i-Discovery
2015-07-02T18:07:33 < jadew> fuck you all!
2015-07-02T18:07:40 < _Sync_> why the fuck did they buy an old tek scope

2015-07-02T18:08:16 < Tectu> Laurenceb, will be working on it tonight.
2015-07-02T18:08:21 < Laurenceb> cool
2015-07-02T18:08:28 < Tectu> Laurenceb, DMA2D will be there within the next few weeks too

2015-07-02T18:08:49 < Tectu> Laurenceb, DMA2D and ChromART are now on top of the agenda beside the ugfx-studio beta release that should take place next week
2015-07-02T18:08:52 < Laurenceb> all internal memory right?
2015-07-02T18:09:04 < Laurenceb> as F7discovery has a ton of external

2015-07-02T18:09:29 < Tectu> Laurenceb, yeah man. itś a fucking awesome board. I am sure this is going to be a very popular board. Hence I want to get ugfx support out ASAP

2015-07-02T18:09:55 < jadew> _Sync_, where?
2015-07-02T18:09:55 < Tectu> Laurenceb, I guess ugfx will run on the board within a few hours. Just no DMA2D yet
2015-07-02T18:09:59 < Tectu> Laurenceb, sure
2015-07-02T18:10:09 < Tectu> Laurenceb, ugfx never ever required any form of frame buffer.

2015-07-02T18:10:49 < Laurenceb> it has capacitive touch?

2015-07-02T18:11:20 < _Sync_> yeah probably
2015-07-02T18:11:24 < Laurenceb> dongs: its blink synced

2015-07-02T18:11:33 < Tectu> Laurenceb, okay, I am starting on ugfx support now. cu
2015-07-02T18:11:42 < Laurenceb> he is blinking
2015-07-02T18:12:05 < Tectu> Laurenceb, but tons of RAM on that board, really

2015-07-02T18:13:49 < _Sync_> the fuck
2015-07-02T18:13:54 < _Sync_> why is certification taking that long

2015-07-02T18:14:04 < _Sync_> yeah jadew

2015-07-02T18:14:16 < _Sync_> and the knob looked similar
2015-07-02T18:14:29 < jadew> _Sync_, are they not related in some way?

2015-07-02T18:14:55 < Tectu> dongs, yes, that does not make it closed sores.

2015-07-02T18:16:41 < jadew> 10 mA current resolution? :(
2015-07-02T18:16:51 < dongs> even this riglol shit is better?

2015-07-02T18:17:27 < jadew> even the Korad has 1 mA resolution
2015-07-02T18:17:43 < jadew> don't know about the Rigol

2015-07-02T18:18:35 < _Sync_> the riglol is actually not that bad
2015-07-02T18:18:49 < _Sync_> I'm amazed how shitty the current regulation on my agilent is
2015-07-02T18:18:59 < jadew> which agilent?
2015-07-02T18:19:08 < dongs> yeah riglol is great, i was actually using all 3 voltage outputs on it for some work stuff the other day!
2015-07-02T18:19:08 < jadew> and current regulation is usually shit
2015-07-02T18:19:20 < dongs> pfft
2015-07-02T18:19:26 < dongs> i only regulate leds
2015-07-02T18:19:28 < dongs> and that works

2015-07-02T18:19:43 < jadew> yeah, I only use it so I don't blow stuff up

2015-07-02T18:20:42 < _Sync_> not motervated to go there now
2015-07-02T18:20:47 < dongs> it has current limit, as in, if you draw > that, it will keep CC, and drop voltage

2015-07-02T18:21:49 < _Sync_> for critical stuff I use the laser power supply
2015-07-02T18:22:02 < _Sync_> as it does not overshoot in voltage when switching from CC to CV
2015-07-02T18:22:06 < jadew> I wish they made a shorter tripple power supply

2015-07-02T18:23:03 < _Sync_> it is about as long as every other lab instrument
2015-07-02T18:23:09 < jadew> or maybe they just use a beefy cap?

2015-07-02T18:24:24 < jadew> which part?
2015-07-02T18:25:23 < _Sync_> using a large cap
2015-07-02T18:25:29 < jadew> some power supplies do have beefy caps, even if they're supposed to provide CC mode too
2015-07-02T18:25:45 < jadew> it's the shitty shortcut to "good ripple"
2015-07-02T18:25:57 < jadew> also, the current regulation could be done after the cap
2015-07-02T18:26:26 < dongs> prety sure riglol stuff is linear, or whatever, go look at eevbeg teardown of that shit
2015-07-02T18:26:42 < jadew> and only the CC release curve to be smoother
2015-07-02T18:27:13 < _Sync_> most laser supplies use very fast current loops with super low output capcitance
2015-07-02T18:27:23 < _Sync_> in the nf range, because otherwise the diodes will be killed

2015-07-02T18:30:18 < jadew> interesting, I guess there aren't many that go higher in voltage?
2015-07-02T18:30:20 < dongs> cool
2015-07-02T18:30:59 < _Sync_> there is no need
2015-07-02T18:31:05 < dongs> http://www.ebay.com/itm/181755288378 is this useful?

2015-07-02T21:34:32 < Tectu> pwned
2015-07-02T21:34:42 < Getty> its about the specific taste of red bull
2015-07-02T21:34:50 < Tectu> Steffanx, why so much rage about the zano thingy? (seriously now(
2015-07-02T21:34:50 < Getty> and the others taste like garbage
2015-07-02T21:35:03 < Tectu> Getty, red bull is nearly liquid gold here
2015-07-02T21:35:06 < Tectu> can´t afford it
2015-07-02T21:35:18 < Tectu> 250cl can is like 4eur

2015-07-02T21:38:21 < Getty> we actually knew and still forced greece into the euro zone
2015-07-02T21:38:30 < Tectu> let me know when you need some money. still got your gold in my basement

2015-07-02T21:39:03 < Getty> most economist in germany knew it already upfront ;)
2015-07-02T21:39:06 < Getty> but politicans
2015-07-02T21:39:20 < Getty> "we want that greece language on the euro, we dont want that "added up later", let greece in"
2015-07-02T21:39:41 < Getty> all other european countries: "if you say so, big master germany" (at that point 33% of the Euro zone)
2015-07-02T21:40:49 < Getty> the best part on all this, in my eyes, is still the fact that not all government departments in greece are using computer

2015-07-02T21:45:19 < Steffanx> and all small thing takes weeks or months to complete.. so it aint better
2015-07-02T21:45:38 < Steffanx> *things take
2015-07-02T21:46:46 < Tectu> here everything takes at least four years
2015-07-02T21:47:04 < Tectu> because 85% of our politicians are 50% full time workers
2015-07-02T21:47:08 < Tectu> and 50% politicians
2015-07-02T21:47:29 < Fleck> imo that's good
2015-07-02T21:48:37 < Tectu> it indeed is. This way their decisions are not only based on their actual real-life experience but they also affect themselves.
2015-07-02T21:48:46 < Tectu> the only downside I know is that everything happens a bit slower
2015-07-02T21:49:45 < trepidaciousMBR2> UK politicians are nearly all wastrels who've never worked a day in their lives, went to fancy "exclusive" schools, etc.

2015-07-02T21:53:28 < Tectu> trepidaciousMBR2, yep. Here it is exactly the other way around. And in my personal opinion that is the right way. Most of those people even run their own companies etc.
2015-07-02T21:54:45 < Tectu> they use the regular public transports like the regular people do
2015-07-02T21:54:51 < Tectu> no fancy private limo driver shit
2015-07-02T21:55:05 < Tectu> they know how real life is so they can judge what impact their decisions will have
2015-07-02T21:55:55 < trepidaciousMBR2> These guys know nothing much about anything except politics, e.g. never admit you're wrong, cover up any mistakes, if in doubt commission some experts to review and then ignore them, if someone takes you out for a nice dinner they must be nice people so you should buy their IT system/plan to frack for gas etc., if people aren't voting for you try to scare the living daylights out of them and offer to "rescue" them from whatever
2015-07-02T21:55:55 < trepidaciousMBR2> threat you've just waved at them
2015-07-02T21:56:09 < Laurenceb_> wait are you talking about zano?
2015-07-02T21:56:15 < trepidaciousMBR2> :)
2015-07-02T21:56:34 < Tectu> trepidaciousMBR2, sounds like a big pain :(
2015-07-02T21:56:40 < trepidaciousMBR2> They don't even go into real jobs when they leave - they go consult for companies, but not on anything factual, just on how to get access to government money/influence
2015-07-02T21:57:02 < Tectu> trepidaciousMBR2, when I am sitting in the train at 06:30 am I often see one of our highest politicians sitting in the same train coach.
2015-07-02T21:57:06 < trepidaciousMBR2> Yup, best thing is to try to ignore them and get on with something worthwhile - it's our own fault, we vote for idiots
2015-07-02T21:57:12 < trepidaciousMBR2> Tectu: Sounds awesome
2015-07-02T21:57:31 < trepidaciousMBR2> If they did that here they'd probably get thrown off the train ;)
2015-07-02T21:57:37 < Tectu> trepidaciousMBR2, try to get the same system in your country :)
2015-07-02T21:58:03 < trepidaciousMBR2> Tectu: I can vote how I want, but I can't do much about the selection of parties or how everyone else votes :(
2015-07-02T21:58:50 < Tectu> trepidaciousMBR2, you should take a look at how Hitler did it. He was a stupid painter who wanted to go to art school and he ended up taking over an entire empire
2015-07-02T21:59:10 < trepidaciousMBR2> Yeah we've got one of those - Nigel Farage ;)
2015-07-02T21:59:11 < Tectu> (not trying to promote that behavior, just saying that it is possible and it happened a few times)
2015-07-02T21:59:17 < Tectu> trepidaciousMBR2, gotta look that up
2015-07-02T21:59:49 < trepidaciousMBR2> Anyone seen this board? https://www.96boards.org/products/ce/dragonboard410c/
2015-07-02T22:02:40 < Tectu> has anybody worked with the new STM32Cube HAL thing here? how can I get the value of the actual systick? HAL_GetTick() returns a value in milliseconds... its value is being incremented every microsecond in the ISR
2015-07-02T22:02:56 < trepidaciousMBR2> They run a 1MHz interrupt?
2015-07-02T22:03:35 < Tectu> trepidaciousMBR2, no idea. I see that my delay is not working properly by using that API and Fleck found out that it is a value that is incremented every ms
2015-07-02T22:04:19 < trepidaciousMBR2> Ah did you mean millisecond not microsecond?
2015-07-02T22:04:33 < Tectu> yep, sorry
2015-07-02T22:04:38 < Tectu> silly me
2015-07-02T22:04:54 < trepidaciousMBR2> I was thinking that would be a bit fast for an interrupt, if you wanted to do anything else :)
2015-07-02T22:05:04 < trepidaciousMBR2> Sorry I can't actually help though ;)
2015-07-02T22:05:14 < trepidaciousMBR2> I've not used cube
2015-07-02T22:05:16 < Tectu> no worries, thanks ;)
2015-07-02T22:05:22 < Tectu> I only use the HAL
2015-07-02T22:05:36 < trepidaciousMBR2> With ChibiOS?
2015-07-02T22:05:51 < Tectu> trepidaciousMBR2, no chibios involved this time
2015-07-02T22:06:12 < trepidaciousMBR2> Ah right
2015-07-02T22:06:21 < Tectu> trepidaciousMBR2, and I have seen thatboard somewhere I think
2015-07-02T22:06:32 < trepidaciousMBR2> It looks pretty nice for $75
2015-07-02T22:06:42 < Tectu> it indeed does
2015-07-02T22:06:49 < trepidaciousMBR2> Can't find too much info though, I was wondering whether schematics were available
2015-07-02T22:07:02 < Tectu> it seems to have WLAN and Bluetooth onboard
2015-07-02T22:07:09 < trepidaciousMBR2> Yup and GPS I think
2015-07-02T22:07:15 < Tectu> wut?
2015-07-02T22:07:22 < Tectu> oh yes
2015-07-02T22:07:24 < Tectu> neis
2015-07-02T22:07:29 < trepidaciousMBR2> Yup pretty unusual
2015-07-02T22:07:36 < Tectu> I should ask them if I can get one or two for free >D
2015-07-02T22:07:38 < trepidaciousMBR2> Plus recent Android
2015-07-02T22:07:41 < trepidaciousMBR2> Heh yeah :)
2015-07-02T22:08:34 < trepidaciousMBR2> Kind of weird that it has no ethernet, but I guess USB would solve that
2015-07-02T22:08:36 < Tectu> but it misses one crucial feature to be successful
2015-07-02T22:08:40 < Tectu> arduino headers
2015-07-02T22:08:52 < Tectu> trepidaciousMBR2, too bulky I guess
2015-07-02T22:08:58 < trepidaciousMBR2> Heh yeah :) Apparently there is an adaptor board though
2015-07-02T22:11:58 < Tectu> quad SPI interface... F4 didnt have that, eh?
2015-07-02T22:12:08 < trepidaciousMBR2> F7 does I think
2015-07-02T22:12:24 < Tectu> yep, just saw that
2015-07-02T22:12:32 < Tectu> it shouldnt
2015-07-02T22:12:33 < Tectu> way too fancy
2015-07-02T22:12:43 < trepidaciousMBR2> Heh
2015-07-02T22:12:59 < trepidaciousMBR2> I guess they just keep finding stuff to add. Would be nice to have support for more modern RAM
2015-07-02T22:13:07 < trepidaciousMBR2> SDRAM seems to be a bit of a pain to find
2015-07-02T22:13:20 < Tectu> trepidaciousMBR2, what would you like? DDR crap?
2015-07-02T22:13:24 < Tectu> afaik Atmel SAM does that
2015-07-02T22:13:38 < Tectu> but DDR is such a bitch when it comes to layouting
2015-07-02T22:13:52 < trepidaciousMBR2> Tectu: Just something you could buy from a number of people, and not worry they will stop making it next year ;)

2015-07-03T02:31:44 < Tectu> Laurenceb_, better save that money for zno
2015-07-03T02:31:46 < Tectu> zano
2015-07-03T02:32:07 < Laurenceb_> heh
2015-07-03T02:32:20 < Laurenceb_> do you have working graphics on F7 discovery?
2015-07-03T02:33:20 < Tectu> Laurenceb_, nope. Currently PaulFertser is trying to help me getting OpenOCD running.
2015-07-03T02:33:30 < Tectu> Laurenceb_, but uGFX itself is running on the board. just no graphics driver yet
2015-07-03T02:33:34 < Laurenceb_> ah
2015-07-03T02:33:48 < Laurenceb_> doesnt it have the standard F103 interface?
2015-07-03T02:34:19 < Tectu> Laurenceb_, F103 interface?
2015-07-03T02:34:24 < Laurenceb_> the st-link
2015-07-03T02:35:03 < Tectu> Laurenceb_, yes. F103CB
2015-07-03T02:35:15 < Laurenceb_> ok, so should be fairly simple?
2015-07-03T02:36:16 < Tectu> Laurenceb_, the problem is not the STLink but that there is currently no M7 support
2015-07-03T02:36:23 < Laurenceb_> yeah i get it

2015-07-03T02:37:02 < Laurenceb_> the SWD interface is basically unchanged?
2015-07-03T02:39:55 < Tectu> Laurenceb_, I dont know how much work it is / was. The patches that PaulFertser is currently hand feeding to me are multiple thousand lines. I dont know how much copy pasting of existing data that is. Ask PaulFertser. I am just a happy user
2015-07-03T02:40:08 < Laurenceb_> wtf
2015-07-03T02:40:10 < Laurenceb_> eeeeekk
2015-07-03T02:40:24 < Laurenceb_> I'd have thought itd just be some ID codes
2015-07-03T02:40:42 < Laurenceb_> obviously I dont have a full understanding of this stuff
2015-07-03T02:40:59 < Tectu> Laurenceb_, I did too. Thats why I took the stm32f4x.cfg file and updated the ID codes according to the RM when I was desperate while PaulFertser was afk
2015-07-03T02:41:15 < Tectu> obviously it didnt work
2015-07-03T02:41:23 < Tectu> cuz me such noob
2015-07-03T02:41:33 < Laurenceb_> hehe thats exactly what I would have tried
2015-07-03T02:42:09 < Tectu> yes, because we´re both insane idiots that dont know shit, right?
2015-07-03T02:42:19 < Laurenceb_> hehe
2015-07-03T02:42:21 < PaulFertser> Laurenceb_: apparently CM7 requires: 1. a little tweak to handle flash breakpoints properly. 2. stm32f7 has a different flash controller (similar to stm32f2x iirc).
2015-07-03T02:42:31 < Laurenceb_> oh of course
2015-07-03T02:42:38 < Laurenceb_> you need the flash bootloader thing
2015-07-03T02:42:40 < Laurenceb_> eww
2015-07-03T02:42:56 < Laurenceb_> still, nice work :D
2015-07-03T02:43:05 < PaulFertser> ST guys wrote it and posted for upstream inclusion.
2015-07-03T02:43:10 < Laurenceb_> ST are so inconsistent :-/
2015-07-03T02:43:43 < Laurenceb_> ST submit openOCD code?
2015-07-03T02:43:59 < PaulFertser> Yes
2015-07-03T02:44:14 < Fleck> nice ;)
2015-07-03T02:44:20 < Laurenceb_> ah cool
2015-07-03T02:44:32 < Tectu> not sure if nice is the right word here, Fleck
2015-07-03T02:44:35 < Laurenceb_> I should get OpenOCD running - I use st-link atm
2015-07-03T02:44:40 < Tectu> all the ST code I saw so far was horrible
2015-07-03T02:44:42 < Laurenceb_> heh
2015-07-03T02:44:43 < Laurenceb_> yeah
2015-07-03T02:44:50 < Fleck> ;p
2015-07-03T02:47:13 < Tectu> Laurenceb_, we should both start working at ST
2015-07-03T02:47:32 < Laurenceb_> no thanks

2015-07-03T02:48:41 < Tectu> maye half a year
2015-07-03T02:48:41 < Laurenceb_> well.. I worked on Galileo contract
2015-07-03T02:48:53 < Tectu> Laurenceb_, sounds nice. Are you still doing medical stuff?
2015-07-03T02:49:09 < Laurenceb_> heh I prefer more fundamental physics stuff with a bit of code
2015-07-03T02:49:21 < Laurenceb_> pure code and stuff bores me
2015-07-03T02:49:46 < Laurenceb_> Galileo was fun - ~100k pages of documentation
2015-07-03T02:50:02 < Tectu> that you wrote?
2015-07-03T02:50:11 < Laurenceb_> no lol
2015-07-03T02:50:22 < Laurenceb_> there was about 60 of us working on it
2015-07-03T02:50:36 < Laurenceb_> but they one the contract, so success I guess
2015-07-03T02:51:09 < Laurenceb_> Galileo is quite funny, its like 50% old soviet junk
2015-07-03T02:51:20 < Laurenceb_>  "junk"
2015-07-03T02:51:49 < Laurenceb_> lots of reconditioned recycled "uprated" stuff
2015-07-03T02:52:00 < Tectu> when it flies it works, right?
2015-07-03T02:52:05 < Laurenceb_> I guess
2015-07-03T02:52:05 < Tectu> should be motto of zano
2015-07-03T02:52:09 < Laurenceb_> its pretty simple
2015-07-03T02:52:24 < Laurenceb_> basically an FPGA and a bunch of soviet radio kit
2015-07-03T02:53:13 < Tectu> can you do h.264 and video streaming fullhd with stabilization at 30 fps?
2015-07-03T02:53:38 < Laurenceb_> hahaha lol
2015-07-03T02:53:44 < Laurenceb_> no even Galileo cant do that
2015-07-03T02:54:08 < Laurenceb_> just signal generation at a few Mbps
2015-07-03T02:54:33 < Tectu> so gotta replace all galileo satelites by low gravity zano in the next decade?

2015-07-03T04:34:47 < dongs> As some may have read in the comments of the latest Shipment update from June 25, i urgently need the Zano for a unique travelling opportunity in the US from end of July to mid September. It's kind of a sabbatical, together with my family, a once-in-a-lifetime thing.
2015-07-03T04:34:51 < dongs> As i am in the latter half of the backers queue, i lost hope to receive my two Zanos (black and white) in time for this vacation. It seems that maybe the first 1000 backers have a chance to receive their Zano in July. I am currently exploring any option to get a hold of a Zano during my vacation.
2015-07-03T04:34:56 < dongs> i should offer this guy a zano at 3x the price

2015-07-03T05:25:28 < dongs> hmm
2015-07-03T05:25:39 < dongs> in boost converter, inductor  peak to peak current increases as vin increaseA?
2015-07-03T05:26:38 < dongs> IPP = 1 / ( 33uH * ( ( 1 / ( 55V - 12V ) ) + (1 / 12V ) ) * 370kHz ) = 770mA vs
2015-07-03T05:26:42 < dongs> IPP = 1 / ( 33uH * ( ( 1 / ( 55V - 24V ) ) + (1 / 24V ) ) * 370kHz ) = 1.2A
2015-07-03T05:28:43 < emeb_mac> where'd you get that equation?
2015-07-03T05:29:12 < zyp> I'd expect it do decrease
2015-07-03T05:29:26 < emeb_mac> that's what I was thinking

2015-07-03T05:29:49 < dongs> unles i fucked up transcribing it
2015-07-03T05:30:34 < dongs> but wolframdongs seems to draw it same as here
2015-07-03T05:30:55 < dongs> http://www.wolframalpha.com/input/?i=1+%2F+%28+33uH+*+%28+%28+1+%2F+%28+55V+-+24V+%29+%29+%2B+%281+%2F+24V+%29+%29+*+370kHz+%29
2015-07-03T05:32:45 < emeb_mac> trying to think of how that equation relates to circuit...
2015-07-03T05:33:33 < dongs> http://i.imgur.com/QZdYd9g.png
2015-07-03T05:33:40 < dongs> rest of stuff
2015-07-03T05:33:53 < dongs> not using that part, but im calculating inductor for something else
2015-07-03T05:34:04 < dongs> and they had a wnice writeup
2015-07-03T05:34:28 < emeb_mac> oh - i see
2015-07-03T05:34:42 < emeb_mac> the ripple current is how much the current varies across the cycle
2015-07-03T05:35:06 < emeb_mac> with higher input voltage the switcher spends less time on, so ripple is higher
2015-07-03T05:35:16 < zyp> ah, of course
2015-07-03T05:35:22 < zyp> I were thinking average
2015-07-03T05:35:22 < emeb_mac> but ripple isn't peak current
2015-07-03T05:35:34 < zyp> or peak
2015-07-03T05:36:31 < emeb_mac> peak current thru the inductor is given below - Ip = Idc + Ipp/2
2015-07-03T05:37:49 < emeb_mac> so if you're trying to size the inductor you'll have to get the dc and ripple both
2015-07-03T05:39:32 < emeb_mac> lol - listening to a french internet radio. playing song where the only lyrics are "Japanese Electronics" over and over...
2015-07-03T05:50:40 < dongs> emeb_mac: right
2015-07-03T05:50:53 < dongs> i just meant that this peak-to-peak current thing increasing.
2015-07-03T05:50:59 < dongs> and you answered w/the ;'less on part'
2015-07-03T05:53:53 < zyp> why is ripple current interesting anyway? magnetic noise?
2015-07-03T05:56:14 < dongs> hm wtf
2015-07-03T05:56:50 < dongs> zyp, not sure, other than its part of the final equation to find out max inductor curent
2015-07-03T05:57:03 < emeb_mac> that
2015-07-03T05:57:29 < emeb_mac> also relates to how much filtering you'll need on the output.

2015-07-03T08:21:28 < jadew> nice try
2015-07-03T08:21:36 < jadew> you were drawing cocks.
2015-07-03T08:21:41 < dongs> yeah i was gonna say
2015-07-03T08:21:51 < dongs> the boobs/pussies shit was jsut added so that we don't think you're gay
2015-07-03T08:21:53 < dongs> wrong
2015-07-03T08:24:44 < dongs> suuure
2015-07-03T08:26:06 < jadew> I was drawing naked chicks too
2015-07-03T08:26:21 < jadew> but I was only able to draw them in only one position
2015-07-03T08:26:23 < jadew> standing
2015-07-03T08:26:33 < jadew> so it got boring fast

2015-07-03T08:50:28 < jadew> I used to know a gay dude, fairly normal if you ignored the occasional lipstick and gay sex stories
2015-07-03T08:51:09 < jadew> had a weird bunch of friends back then
2015-07-03T08:52:01 < jadew> not really, he was the friend of a friend
2015-07-03T08:52:17 < jadew> she stopped talking to me after I got a girlfriend tho
2015-07-03T08:52:24 < jadew> the first friend
2015-07-03T08:52:43 < jadew> the first friend was a girl
2015-07-03T08:52:59 < jadew> so girl, had a gay friend (and a whore friend, but that's another story)
2015-07-03T08:53:07 < jadew> and I was friends with the girl
2015-07-03T08:53:11 < jadew> really good friends actually
2015-07-03T08:53:36 < jadew> the whore was really hot
2015-07-03T08:54:03 < jadew> you don't, it sounds gay
2015-07-03T08:54:34 < jadew> I say "you're hot, let's bang!"
2015-07-03T08:55:08 < jadew> but that might not work so well on women I'm not married with :P
2015-07-03T08:56:50 < jadew> you might say "you're beautiful", if you're on the... first date or something
2015-07-03T08:57:03 < jadew> esti frumoasa

2015-07-03T08:59:13 < jadew> and he asked me what something means
2015-07-03T08:59:19 < jadew> it meant wanker
2015-07-03T08:59:33 < jadew> apparently a romanian waitress said that to him with a smile on her face :P
2015-07-03T08:59:44 < jadew> he thought it was something nice

2015-07-03T10:49:22 < dongs> Hi guys, I think that Zano doesn't work as well as expected by the creator, otherwise, we have already see pictures and video taken by the Zano, at least from the prototypes. It's not a disaster, but I'm sure that Zano will not be sent before the end of summer. I hope I'm wrong.

2015-07-03T14:08:45 < dongs> to send that garbage back!
2015-07-03T14:12:52 < karlp> when you're measuring picoamps and femtoamps with that meter laurence linked, like http://www.keysight.com/en/pc-2444652/b2980a-series-femto-picoammeter-and-electrometer-high-resistance-meter?&cc=GB&lc=eng, how is it wired up? what sort of connections will that use?
2015-07-03T14:13:22 < dongs> i would imagine very expensive
2015-07-03T14:14:32 < dongs> i wonder what the bandwidth on that is

2015-07-04T02:39:06 < Laurenceb_> my driver turned into a mess, but the original idea was to configure "transaction descriptors" with data input and output buffer pointers and callback function pointers
2015-07-04T02:39:13 < Laurenceb_> imo thatd be the ideal i2c driver
2015-07-04T02:39:25 < Laurenceb_> then add a transaction queue with priorities
2015-07-04T02:39:51 < Laurenceb_> also making it thread safe, so multiple threads can use the same bus
2015-07-04T02:39:56 < TheSeven> the descriptors are similar here

2015-07-04T02:43:20 < Laurenceb_> thats another idea i had - totally generic i2c datalogger
2015-07-04T02:43:41 < Laurenceb_> thats USB mass storage with xml file or something to define all the bus config
2015-07-04T02:43:47 < TheSeven> heh yeah, the driver is completely event/IRQ driven internally
2015-07-04T02:43:54 < TheSeven> just blocking on a "while (busy) idle();" construct ;)
2015-07-04T02:44:04 < TheSeven> so reworking that is trivial :)
2015-07-04T02:44:33 < Laurenceb_> itd make a nice kickstarter... maybe
2015-07-04T02:44:40 < Laurenceb_> universal i2c datalogger
2015-07-04T02:44:54 < TheSeven> my data logging so far has been mostly temperature sensors on 1wire bus
2015-07-04T02:45:17 < TheSeven> focusing on cutting costs down and optimizing battery life
2015-07-04T02:45:34  * Laurenceb_ was looking at vehicle vibration
2015-07-04T02:45:39 < TheSeven> so that's a completely different approach I guess
2015-07-04T02:45:40 < Laurenceb_> hmm actually
2015-07-04T02:45:48 < Laurenceb_> F4 DMA is actually decent
2015-07-04T02:45:58 < Laurenceb_> surely I2C via DMA is the sensible way
2015-07-04T02:46:56 < TheSeven> heh in my case I'm slapping tons of data logger boards into dozens of rooms to collect information about workplace air condition
2015-07-04T02:47:29 < TheSeven> so yeah, they should run for months on 2x AA batteries, and cost <10€ a piece (in parts)

2015-07-04T02:48:01 < TheSeven> hm, not sure if DMA would really have much benefit there - aren't most I2C transfers rather tiny?
2015-07-04T02:48:09 < Laurenceb_> true
2015-07-04T02:48:19 < TheSeven> guess you can't offload all the start/stop/repeatstart/addressing stuff to it
2015-07-04T02:48:27 < Laurenceb_> hmm looks like F2/4 I2C is basically F1 I2c with some sanity fixes
2015-07-04T02:48:35 < TheSeven> so just chewing descriptors in IRQ handlers seems somewhat sane
2015-07-04T02:48:43 < Laurenceb_> so you can shut down master tx much more simply
2015-07-04T02:48:48 < Laurenceb_> yeah
2015-07-04T02:49:01 < Laurenceb_> figure 243 is the RM
2015-07-04T02:49:03 < Laurenceb_> *in the
2015-07-04T02:49:15 < TheSeven> hm, which rm?
2015-07-04T02:49:26 < TheSeven> 0090?
2015-07-04T02:49:45 < Laurenceb_> yeah
2015-07-04T02:50:07 < Laurenceb_> looks like F1 code with some of the annoyingly complex cases stripped out should work fine
2015-07-04T02:50:43 < TheSeven> I'm doing it the other way - I implemented this based on F2/F4 RMs, and I guess it mostly works on F1 as well
2015-07-04T02:50:57 < TheSeven> with maybe a bunch of ifdefs... not sure if I've ever attempted to run it on F1
2015-07-04T02:51:06 < TheSeven> guess it might run unmodified on F0
2015-07-04T02:51:40  * TheSeven basically hates F1 chips for having all those weird quirks, being "almost compatible" with the newer ones ;)
2015-07-04T02:51:42 < Laurenceb_> F1 I2C is a bit nasty
2015-07-04T02:51:49 < Laurenceb_> heh
2015-07-04T02:51:58 < Laurenceb_> I like the simple RTC on F1
2015-07-04T02:52:10 < Laurenceb_> hate F2/4 etc RTC big time
2015-07-04T02:52:42 < Laurenceb_> someone need to write some conversion function to make it look like a generic timer
2015-07-04T02:53:05 < TheSeven> tbh what annoys me most on F1 (but that might be biased by what I actually had to deal with) is that pinmux disaster, the USB OTG on F105/107 needing that Vbus pin tied high, and the not very flexible clock tree - along with bugs, lots of bugs
2015-07-04T02:53:35 < TheSeven> no idea what the RTCs look like - only worked with that on F0 so far
2015-07-04T02:54:03 < Laurenceb_> I've never used OTG
2015-07-04T02:54:17 < TheSeven> well not really using OTG here, just using the OTG peripheral as device
2015-07-04T02:54:29 < TheSeven> (in contrast to the other core on F103 or whatever)
2015-07-04T02:55:00 < Laurenceb_> ah
2015-07-04T02:55:12 < Laurenceb_> I've just used F103 device
2015-07-04T02:55:21 < TheSeven> this means that the DFU bootloader will only work with PA9 tied high
2015-07-04T02:55:27 < Laurenceb_> ah
2015-07-04T02:55:34 < TheSeven> and that pin is muxed with some crucial pins for ethernet IIRC
2015-07-04T02:55:36 < TheSeven> rather nasty
2015-07-04T02:56:29  * TheSeven was kinda surprised to see F030F4P6 chips only actually have 16K flash and 4K RAM
2015-07-04T02:56:58 < TheSeven> given that there's a 32K model available (but only in a different package)
2015-07-04T02:57:24 < Laurenceb_> http://i.imgur.com/gNQoGUc.jpg
2015-07-04T02:57:32 < Laurenceb_> F103 work project prototype
2015-07-04T02:57:47 < TheSeven> that reminds me, I should re-check china STM32 prices, let's see if these super-cheap suspicious F205 chips are still available ;)
2015-07-04T02:58:16 < Laurenceb_> I dont get the point of F2
2015-07-04T02:58:40 < TheSeven> well, basically F4 with M3 instead of M4 core and cheaper?
2015-07-04T02:58:56 < Laurenceb_> yeah
2015-07-04T02:59:08 < TheSeven> F205 is the perfect match for my STM32 ethernet devboard
2015-07-04T02:59:52 < TheSeven> heh yeah, still up: http://www.aliexpress.com/item/STM32F205RBT6-QFP/32365299266.html
2015-07-04T02:59:53 < kakimir_> what is that pumpin?
2015-07-04T03:00:00 < TheSeven> apparently air
2015-07-04T03:00:28 < Laurenceb_> yeah, air
2015-07-04T03:01:02 < kakimir_> to what?
2015-07-04T03:01:38 < TheSeven> 80 cents shipped @100pcs seems insanely cheap for that chip - can't quite believe that this offer is legit
2015-07-04T03:01:50 < kakimir_> is this some baloon stuff?
2015-07-04T03:01:51 < Laurenceb_> blood pressure cuffs
2015-07-04T03:01:55 < kakimir_> oo
2015-07-04T03:01:57 < kakimir_> okay
2015-07-04T03:02:02 < Laurenceb_> no, experimental medical thing
2015-07-04T03:02:53 < kakimir_> anal pressure stuff
2015-07-04T03:03:00 < Laurenceb_> does ECG and stuff, but also has I2C breakout for MEMS sensors - I use the same boxes for lots of projects, have had loads of them made
2015-07-04T03:03:01 < Laurenceb_> lol
2015-07-04T03:03:23 < TheSeven> hm... will the F205RBT6 have ethernet? ;)
2015-07-04T03:03:45 < TheSeven> I know the larger F205 ones do
2015-07-04T03:04:19 < TheSeven> but there's no B size of the F207, so who knows if that particular one might be a similar special case as with the F030F4P6
2015-07-04T03:04:42 < TheSeven> could well be that it is in fact an F207xGT6 die though
2015-07-04T03:10:17 < TheSeven> guess I should also order a bunch of stm32f072c8t6 for my next project - that's a really nice low-end chip, with lots of features
2015-07-04T03:10:35 < TheSeven> $1.73 a pop in china @50pcs - kinda insane that this costs more than twice than F205 :P
2015-07-04T03:11:00 < TheSeven> s/twice than/twice as much as that/

2015-07-04T14:32:33 < dongs> the part number doenst look liek something common
2015-07-04T14:32:42 < dongs> i mean, i alread picked sc70 and sorted down by rating, cut tape, in stock
2015-07-04T14:32:48 < dongs> so i've looked at all of those
2015-07-04T14:32:54 < jpa-> yea
2015-07-04T14:33:13 < dongs> but.. i see lotsa hits on that part
2015-07-04T14:33:15 < dongs> so maybe its not so bad
2015-07-04T14:33:29 < jpa-> i always just use BSH105 in sot23
2015-07-04T14:33:40 < Tectu> me too

2015-07-04T14:34:12 < dongs> i think that diodes thing will work
2015-07-04T14:34:16 < dongs> china probly has it too

2015-07-04T15:45:14 < Tectu> isnt there some kickstarter rule that says that you get your money back when they dont succeed?
2015-07-04T15:46:54 -!- bvsh_ is now known as bvsh
2015-07-04T15:47:05 < jpa-> no
2015-07-04T15:47:06 < ReadError> they dont get funds unless they hit the goal
2015-07-04T15:47:13 < jpa-> well yeah that
2015-07-04T15:47:31 < jpa-> but if they fail to deliver, you can try getting back through credit card company
2015-07-04T15:47:42 < ReadError> prob is thats only 6mo
2015-07-04T15:47:51 < ReadError> which is in 4 days for zano
2015-07-04T15:48:08 < ReadError> depending when they backed it
2015-07-04T15:50:06 < Steffanx> Tectu, that would be weird anyway. Get your investment back when they fail to deliver
2015-07-04T15:50:40 < Steffanx> one can fail for dozens of reasons  with all money spend.
2015-07-04T15:50:58 < Steffanx> whos going to pay the backers back when all the money is gone?

2015-07-04T15:51:32 < dongs> but designers arent that much brighter
2015-07-04T15:51:50 < ReadError> they should have an escrow or trust system

2015-07-04T15:54:56 < jpa-> ReadError: or do you suggest that kickstarter projects should do 100% of work themselves free, no contractors allowed?
2015-07-04T15:55:16 < dongs> pretty sure zano scrambled to hire some shitty coders
2015-07-04T15:55:19 < dongs> in the last week
2015-07-04T15:55:26 < dongs> but they still won't be able to get anything done
2015-07-04T15:55:34 < ReadError> I thought the idea of kickstarter was to get a product launched
2015-07-04T15:55:43 < ReadError> then you make the real money after
2015-07-04T15:55:50 < ReadError> to buy tooling, equipment etc
2015-07-04T15:56:30 < ReadError> but yea i guess salary
2015-07-04T15:56:47 < jpa-> very rarely does a single person / team have all the knowledge required to develop a product

2015-07-04T15:57:34 < jpa-> zano made that pie chart their logo
2015-07-04T15:58:04 < ReadError> also the product should be fuckin developed before it hits kickstarter
2015-07-04T15:58:29 < Tectu> jpa-, pie chart?
2015-07-04T15:58:33 < jpa-> so, you suggest a more limited kickstarter

2015-07-04T15:59:25 < Tectu> jpa-, in what way more?
2015-07-04T15:59:28 < Steffanx> isn't indiegogo more about total freedom?
2015-07-04T15:59:30 < jpa-> ReadError: zano explicitly said in campaign "The profits made from the Kickstarter campaign will allow us to hire additional engineers, software developers, app developers, product developers, etc."
2015-07-04T15:59:45 < jpa-> yes, indiegogo is like "allow all the crazy shit that kickstarter does not"

2015-07-04T16:12:53 < jpa-> because it *relies* on the mechanics to be crappy enough to take the jerks
2015-07-04T16:12:55 < ReadError> backlash compensation etc
2015-07-04T16:13:04 < dongs> laff
2015-07-04T16:13:07 < dongs> whats better then
2015-07-04T16:13:09 < jpa-> backlash compensation? whut?

2015-07-04T16:13:15 < englishman> lunixcnc seems pretty legit the more I dick with it
2015-07-04T16:13:27 < ReadError> or a MESA card
2015-07-04T16:13:29 < dongs> good luck
2015-07-04T16:13:30 < ReadError> (FPGA)
2015-07-04T16:13:33 < englishman> and the j1800 I got seems to be good
2015-07-04T16:13:51 < jpa-> IMO best would be beaglebone + machinekit
2015-07-04T16:13:57 < jpa-> maybe the cramps board
2015-07-04T16:14:01 < dongs> err,
2015-07-04T16:14:05 < dongs> thats already rlunix
2015-07-04T16:14:09 < dongs> on beagleboner
2015-07-04T16:14:13 < dongs> so thats a non-starter right there
2015-07-04T16:14:18 < ReadError> linuxcnc has a bunch of advanced features tho
2015-07-04T16:14:19 < englishman> isn't it lunixcnc fork
2015-07-04T16:14:22 < jpa-> well the really realtime part is on the realtime processors
2015-07-04T16:14:28 < jpa-> but yes, linuxcnc
2015-07-04T16:14:36 < ReadError> its headless i think
2015-07-04T16:14:53 < jpa-> ? you can run linuxcnc headless or with gui or whatever you want

2015-07-04T16:15:34 < englishman> I'm already set up with j1800+monitor+kb etc

2015-07-04T16:16:10 < ReadError> all the touchoff thing is, switch
2015-07-04T16:16:16 < ReadError> that goes to one of the db25 pins
2015-07-04T16:16:21 < englishman> ya but there's level shifter or something
2015-07-04T16:16:31 < ReadError> ah maybe
2015-07-04T16:16:36 < englishman> theres optos for the switches
2015-07-04T16:16:46 < englishman> but I can boop those
2015-07-04T16:17:07 < ReadError> then when you setup the controller you just tell it which pin
2015-07-04T16:17:12 < ReadError> since you gotta do that anyways
2015-07-04T16:17:15 < englishman> ya been doing that
2015-07-04T16:17:25 < jpa-> englishman: you could also use some program that shows parallel port pin states to test
2015-07-04T16:17:26 < englishman> got xyza but not other stuff
2015-07-04T16:17:58 < englishman> yes good idea
2015-07-04T16:18:08 < englishman> with hand on killswitch
2015-07-04T16:18:40 < jpa-> not like it will puff up in smoke... well actually maybe it could :)
2015-07-04T16:19:09 < jpa-> funny that it has usb, though

2015-07-04T17:40:10 < dongs> i *really* hate reworking designs
2015-07-04T17:40:17 < dongs> especially 4layer shit
2015-07-04T17:40:33  * scummos too
2015-07-04T17:40:41 < Steffanx> redo it instead
2015-07-04T17:40:44 < dongs> end up wanting to reroute like half the shit even if it doesnt need to be
2015-07-04T17:40:45 < dongs> right
2015-07-04T17:40:48 < dongs> redoing is almost faster
2015-07-04T17:41:05 < scummos> push+shove makes it bearable though
2015-07-04T17:41:22 < dongs> sure but it just looks ike ass
2015-07-04T17:41:35 < Steffanx> client cares about that?
2015-07-04T17:41:46 < scummos> do it on the inner layer, nobody will see it then
2015-07-04T17:44:17 < dongs> heh
2015-07-04T17:50:06 < Tectu> dongs, put it on KS, get money, pay somebody else to do it for ya

2015-07-04T18:02:39 < Laurenceb_> link?
2015-07-04T18:02:41 < englishman> i went in there once

2015-07-04T18:07:32 < Laurenceb_> wtf
2015-07-04T18:07:34 < Laurenceb_> u
2015-07-04T18:07:40 < Tectu> dongs, uGFX runs out of the box on FreeRTOS, ChibiOS, eCOS and all the other crap
2015-07-04T18:07:40 < dongs> Tectu: cmsis-os is STANDARD API that your (shitty os can use)
2015-07-04T18:07:41 < Laurenceb_> made your own OS now?

2015-07-04T18:09:39 < Laurenceb_> I thought there was an open CMSIS-RTOS  ?
2015-07-04T18:09:44 < dongs> Laurenceb_: there is
2015-07-04T18:09:51 < dongs> which uses the cmsis-os API
2015-07-04T18:10:08 < dongs> but you don't have to "use" the rtos, you can just write your own shit but use same function signatures/etc

2015-07-04T18:10:58 < Laurenceb_> no kernel there
2015-07-04T18:11:04 < dongs> Laurenceb_: ...
2015-07-04T18:11:14 < dongs> its api/naming convention
2015-07-04T18:11:19 < Laurenceb_> http://www.keil.com/pr/article/1253.htm
2015-07-04T18:11:20 < dongs> for "roll your own shit"
2015-07-04T18:11:23 < dongs> OR
2015-07-04T18:11:25 < dongs> you can use RTX
2015-07-04T18:11:30 < dongs> which is free/opensauce/BSD licensed
2015-07-04T18:11:37 < dongs> and follows that cmsis-os api

2015-07-04T18:11:46 < Laurenceb_> foudn it
2015-07-04T18:11:56 < dongs> yes, that
2015-07-04T18:11:57 < Laurenceb_> wonder why nobody uses it
2015-07-04T18:11:59 < dongs> i do
2015-07-04T18:12:05 < Laurenceb_> nobody on irc :P
2015-07-04T18:12:06 < dongs> i made some stuff on F3 few weeks ago
2015-07-04T18:12:08 < Laurenceb_> ah
2015-07-04T18:12:11 < dongs> took liek 5 mins to bring it up
2015-07-04T18:12:19 < dongs> and have threads running + talking+ stuff
2015-07-04T18:12:27 < Laurenceb_> yeah it looks easy to use
2015-07-04T18:12:27 < dongs> waiting on stuff, snding messages etc.
2015-07-04T18:12:32 < Laurenceb_> but so in Chibios
2015-07-04T18:12:35 < Laurenceb_> *is
2015-07-04T18:15:43 < dongs> how is servomotor more leet
2015-07-04T18:15:49 < dongs> isnt it just a motor geared down?
2015-07-04T18:16:04 < Laurenceb_> its a brushless motor, yeah
2015-07-04T18:16:11 < dongs> right, so whats so amazing about it
2015-07-04T18:16:17 < Laurenceb_> but they usually have very high quality encoders on the end
2015-07-04T18:16:18 < dongs> how is it beter htan sttper
2015-07-04T18:16:27 < dongs> well, yes
2015-07-04T18:16:30 < Laurenceb_> and with a proper controller you can get crazy precision
2015-07-04T18:16:44 < Laurenceb_> but all the kit is very expensive
2015-07-04T18:16:54 < dongs> sounds like time for a dickstarter

2015-07-04T19:06:24 < Rickta59> i just spent some time looking at the cubemx stuff .. and wow .. I used to thing the legacy standard peripheral stuff was fat ..
2015-07-04T19:06:32 < dongs> yeah man.
2015-07-04T19:06:35 < dongs> just say no
2015-07-04T19:06:44 < Rickta59> who is going to actually use that?
2015-07-04T19:06:47 < dongs> stick with stdperiph, or wrap registers into simple stuff
2015-07-04T19:06:51 < dongs> and done
2015-07-04T19:07:10 < Rickta59> and I see that mbed is using that underneath .. like a bacon wrapped stuffed pizza that is
2015-07-04T19:07:14 < MrMobius> ya just use it for initialization
2015-07-04T19:07:31 < dongs> haha wat
2015-07-04T19:07:36 < dongs> Rickta59: mbed uses cube hal shit now?
2015-07-04T19:07:39 < dongs> on stm32
2015-07-04T19:07:42 < Rickta59> yeah
2015-07-04T19:07:53 < dongs> i guess its probly not much worse than NXP C++ aids that it originally did so
2015-07-04T19:09:04 < Rickta59> i was checking out the openstm32 thing .. another half done only works on windows thing .. the integration with the cubemx for that is just broken in so many ways
2015-07-04T19:09:34 < Rickta59> and i used to think the TI stuff was lame .. st is making TI look good
2015-07-04T19:10:10 < MrMobius> Rickta59, cube integration is laughable
2015-07-04T19:10:19 < MrMobius> "here are 13 stepsto go through to get it to import"
2015-07-04T19:10:37 < Rickta59> at least the ti puts their high level api in rom so it is at least zero wait state
2015-07-04T19:10:41 < MrMobius> but otherwise openstm32 is decent dont you think?
2015-07-04T19:10:56 < Rickta59> it is just eclipse with vendor stuff messing it up
2015-07-04T19:11:33 < Rickta59> seems like the winning combination * for linux anyways * is eclipse + the gnu arm plugin
2015-07-04T19:11:47 < Rickta59> winning combination for free stuff
2015-07-04T19:12:02 < MrMobius> i was doing that myself but good luck every using the VCP
2015-07-04T19:12:14 < Rickta59> did you not get that going?
2015-07-04T19:12:16 < MrMobius> there are no examples of that that work with that combination
2015-07-04T19:12:29 < MrMobius> nope, just got cubes nonsense going with openstm32

2015-07-04T19:14:48 < emeb> stdperiph works fine, they still seem to be supporting it and there are plenty of working examples.
2015-07-04T19:15:05 < dongs> hal just adds like 2-3 levels of indirection

2015-07-04T20:47:32 < jpa-> one more reason to use L0
2015-07-04T20:48:37 < englishman> you mean, not to use?
2015-07-04T20:48:49 < jpa-> no
2015-07-04T20:49:10 < jpa-> one less crappy library lurking around
2015-07-04T20:49:54 < emeb> everyone should just use direct register access & code from scratch
2015-07-04T20:50:32 < jpa-> for example yeah, or something sane like libopencm3 or chibios
2015-07-04T20:50:33 < emeb> "It's the only way to be sure"
2015-07-04T20:50:41 < jpa-> nah, its nowhere near sure
2015-07-04T20:50:49 < jpa-> stm32 has enough errata
2015-07-04T20:51:10 < emeb> because libopencm3 and chibios always keep up with the new silicon releases.
2015-07-04T20:51:19 < jpa-> ; speaking of errata, ran into a fun issue on F4 - had to increase flash wait states or got random crashes a few times a year
2015-07-04T20:51:31 < emeb> nifty!
2015-07-04T20:52:07 < jpa-> fortunately they were somewhat repeatable on the affected devices & firmware versions.. some specific order of flash reads triggered it
2015-07-04T20:52:42 < emeb> very odd.
2015-07-04T20:52:59 < emeb> but I've gathered that the flash cache on the F4 is ... interesting.
2015-07-04T20:53:25 < jpa-> not really that odd, similar to what happens when the wait states is too low.. so the spec is just not accurate
2015-07-04T20:53:33 < jpa-> or my circuit has something that worsens it
2015-07-04T20:53:50 < emeb> what's the application?
2015-07-04T20:54:06 < jpa-> signal processing & gui
2015-07-04T20:54:28 < emeb> which f4 part?
2015-07-04T20:54:33 < jpa-> interestingly it usually crashed in the font routine.. nuttx's font stuff has a lot of nested functions so i guess it was happily evicting cache
2015-07-04T20:54:58 < jpa-> STM32F407VGsomething
2015-07-04T20:55:07 < emeb> older part.
2015-07-04T20:55:45 < emeb> what's the board layout like? 4layer, lots of close in bypass on all the supplies?
2015-07-04T20:56:18 < emeb> (ie - solid gnd / power planes?)

2015-07-04T20:57:06 < jpa-> yeah
2015-07-04T20:57:27 < jpa-> http://koti.kapsi.fi/jpa/stuff/pix/vm_pcb.jpg  4 layer, solid gnd and sectioned vcc on the middle layers
2015-07-04T20:58:52 < jpa-> (and yes, the LDOs are compatible with ceramic caps and vcc looks fine also :)
2015-07-04T20:59:38 < emeb> Seems like the ckt should be fine then.
2015-07-04T21:00:17 < jpa-> so it seems to me; pretty much a puzzle why it doesn't meet the spec
2015-07-04T21:01:04 < jpa-> though the fact that it often occurs in font routine makes me think that maybe driving the FSMC bus temporarily takes enough current to disturb the flash
2015-07-04T21:01:26 < emeb> LCD is on the FSMC?
2015-07-04T21:01:30 < jpa-> yea
2015-07-04T21:01:46 < emeb> hmm...
2015-07-04T21:02:06 < emeb> does the extra wait state cause you any heartburn?
2015-07-04T21:02:11 < emeb> (lower throughput, etc)
2015-07-04T21:02:16 < emeb> or can you live with it?
2015-07-04T21:02:27 < jpa-> not really, so it is "problem solved" from business point of view
2015-07-04T21:02:33 < Laurenceb_> is the nuttx graphics any good?
2015-07-04T21:03:00 < jpa-> Laurenceb_: well... it works; it is not terrible; it is not great
2015-07-04T21:03:06 < Laurenceb_> heh
2015-07-04T21:03:10 < Laurenceb_> better than uGFX?
2015-07-04T21:03:19 < jpa-> i haven't tried the gui stuff in ugfx
2015-07-04T21:03:19 < emeb> would be interesting to see if cacheing the LCD data to RAM first, then spewing it out en-masse would help or hurt.
2015-07-04T21:03:38 < jpa-> the drawing primitives lose to ugfx now
2015-07-04T21:03:57 < Laurenceb_> ok
2015-07-04T21:04:09 < jpa-> emeb: maybe, but not nearly enough ram for that
2015-07-04T21:04:28 -!- KreAture_Zzz is now known as KreAture_
2015-07-04T21:04:53 < emeb> jpa-: ya. perhaps not a whole screen buffer, just a temp update buffer.
2015-07-04T21:05:05 < jpa-> yeah, well nuttx does that already
2015-07-04T21:05:25 < jpa-> which basically means that while it is drawing text, it is also spewing the previous temp buffer to fsmc
2015-07-04T21:05:36 < emeb> via dma
2015-07-04T21:05:40 < jpa-> yes
2015-07-04T21:05:49 < Laurenceb_> does it support dma2d?
2015-07-04T21:06:01 < jpa-> no idea, f407 doesn't have that
2015-07-04T21:06:24 < emeb> ah - could try putting a lock on so new buffer doesn't draw while old buffer is updating.
2015-07-04T21:06:24 < jpa-> it would probably be within the LCD driver anyway
2015-07-04T21:06:48 < jpa-> yeah, though IMO increasing wait states is a preferrable solution
2015-07-04T21:06:54 < jpa-> for testing one could just disable the FSMC
2015-07-04T21:06:58 < emeb> right - slower than wait
2015-07-04T21:07:22 < emeb> well, whipping a dead horse.
2015-07-04T21:07:49 < jpa-> goes down to the book of unsolved stm32 mysteries :)

2015-07-04T21:08:28 < jpa-> and some software also

2015-07-04T23:36:33 < upgrdman> i gave an stm32f4 around 7V for about 20 seconds before i realized it. still works to this day
2015-07-04T23:37:27 < TheSeven> ok, I only did that with 5V (but longer times)
2015-07-04T23:37:30 < upgrdman> only reason why i even noticed was the lcd i also had on the "3.3V" rail has the contrast way high at that votlage
2015-07-04T23:37:31 < TheSeven> 12V definitely kills it though
2015-07-04T23:41:28 < Laurenceb_> I've put -5V into an F4
2015-07-04T23:41:32 < Laurenceb_> blew the top off

2015-07-05T00:41:53 < Laurenceb_> yes
2015-07-05T00:42:10 < Laurenceb_> but I set the GPIO and ran NVIC_SystemReset
2015-07-05T00:42:48 < Blok> Thats what I am doing now, but I want to run it from SW
2015-07-05T00:45:01 < Blok> This is what I am doing: http://pastebin.com/p389KmPn
2015-07-05T00:46:11 < Blok> I initiate the bootloader by writing the magic number to backup reg 5 followed by reset.
2015-07-05T00:47:10 < Laurenceb_> yeah i see
2015-07-05T00:47:19 < Laurenceb_> you might need to set stack pointer and stuff
2015-07-05T00:47:29 < Laurenceb_> can you break after line 11?
2015-07-05T00:48:18 < Blok> I have no debugger at hand right now :(
2015-07-05T00:48:19 < Laurenceb_> also I find entering bootloader with usb connector fails
2015-07-05T00:48:26 < Laurenceb_> you are screwed then

2015-07-05T00:53:01 < Blok> What should my stack address be? When I set it to what I belive it should be it does not even work in the "working case".
2015-07-05T00:56:39 < Laurenceb_> I dunno...
2015-07-05T00:56:57 < Laurenceb_> maybe BL expects it to be all zeros

2015-07-05T07:54:13 < jadew> I wonder if seek is constrainted in how they can process the images, because the images the original application generates are really bad compared to what the sensor is capable of
2015-07-05T07:54:42 < jadew> apparently they even had to cripple the sensor because of a lawsuit from Flir

2015-07-05T08:39:51 < zyp> I like the idea of super small fpgas
2015-07-05T08:40:07 < zyp> why buy a fixed function chip when you can just throw a small fpga at it?
2015-07-05T08:40:16 < zyp> just a shame the toolchain is still shit
2015-07-05T08:41:04 < dongs> whats with the lattice freetard toolchain?
2015-07-05T08:41:08 < emeb_mac> be nice if they came in more reasonable pkgs
2015-07-05T08:41:09 < dongs> is it official?
2015-07-05T08:41:20 < dongs> or some gcc  hax
2015-07-05T08:41:34 < emeb_mac> one qfn in that family - all the rest is bga or csp
2015-07-05T08:41:42 < zyp> I mean fpga toolchain
2015-07-05T08:41:54 < dongs> right
2015-07-05T08:42:00 < dongs> the hackaday shit implied there was some "opensores" toolchian
2015-07-05T08:42:08 < dongs> or maybe it was jsut  free
2015-07-05T08:42:10 < zyp> hmm, I think I bought that icestick or whatever devboard for it
2015-07-05T08:42:22 < dongs> i still have a bunch of actel dev shit
2015-07-05T08:42:25 < zyp> but I never got around to actually doing anything with it

2015-07-05T08:43:18 < dongs> they just need to be GOOD

2015-07-05T08:44:12 < emeb_mac> I have my doubts
2015-07-05T08:44:26 < dongs> yeah?
2015-07-05T08:44:27 < zyp> also portability and shit
2015-07-05T08:44:28 < dongs> well zyp
2015-07-05T08:44:32 < dongs> how long has lunix been "open"?
2015-07-05T08:44:37 < dongs> like 20=-30 years?
2015-07-05T08:44:39 < dongs> and its still shit

2015-07-05T08:45:09 < emeb_mac> portability is not possible at the macro level - all FPGA IP is very different.
2015-07-05T08:45:24 < emeb_mac> best hope is to code in generic HDL and hope the tools are good at inferrence
2015-07-05T08:45:26 < zyp> emeb_mac, I mean host portability, not target portability
2015-07-05T08:45:43 < dongs> all teh pros use windows
2015-07-05T08:45:45 < dongs> it is fact
2015-07-05T08:45:49 < emeb_mac> well, tools run on win and linux. what else do you want?
2015-07-05T08:45:49 < PeterM> why does host portability matter?
2015-07-05T08:45:54 < dongs> it does not
2015-07-05T08:46:08 < zyp> emeb_mac, IIRC the ice tools are windows only
2015-07-05T08:46:15 < emeb_mac> al
2015-07-05T08:46:18 < emeb_mac> aha
2015-07-05T08:46:23 < dongs> cross-platform: shit on all supported platforms
2015-07-05T08:46:46 < emeb_mac> zyp: Wine! :P
2015-07-05T08:46:57 < dongs> you cant be se rious
2015-07-05T08:47:03 < zyp> heh
2015-07-05T08:47:04 < emeb_mac> diptrace sorta runs under wine. sorta.
2015-07-05T08:47:06 < dongs> hm now they're just playing a bunch of 4K timelapses
2015-07-05T08:47:10 < emeb_mac> dongs: I'm not.
2015-07-05T08:47:24 < dongs> emeb_mac: err, mac version of dicktarce IS wine
2015-07-05T08:47:36 < dongs> it usew whinelib or hwatever
2015-07-05T08:47:51 < emeb_mac> yep
2015-07-05T08:48:02 < emeb_mac> and it works on linux too. sorta. :)

2015-07-05T09:15:28 < dongs> I don't think that Instagram video of the black Zano is filled by another Zano.
2015-07-05T09:15:29 < dongs> The depth of field is very shallow....I wouldn't imagine Zano would be able achieve that effect (would need to control aperture and have a zoom lens to maximise blurring effect such as this)

2015-07-05T09:21:47 < dongs> this is the video in question
2015-07-05T09:22:07 < jadew> wait, they say another zano took that?
2015-07-05T09:22:44 < emeb_mac> bullshit
2015-07-05T09:22:50 < jadew> of course
2015-07-05T09:22:56 < dongs> 100% bullshit, of course
2015-07-05T09:23:42 < jadew> what lens does it have?
2015-07-05T09:23:49 < dongs> the one in that picture
2015-07-05T09:23:55 < dongs> on the black zaNO
2015-07-05T09:24:06 < jadew> I think my lumia 920 can achieve shallow DOF for upclose shots
2015-07-05T09:24:19 < jadew> give me a sec to test this
2015-07-05T09:24:51 < jadew> no
2015-07-05T09:26:26 < jadew> would have been more interesting to see the zano taking that video, in a videa
2015-07-05T09:26:28 < jadew> *video
2015-07-05T09:27:00 < dongs> http://i.imgur.com/UAvwQAP.jpg my S6 can sorta do it
2015-07-05T09:27:32 < jadew> what if it's a bit farther away?
2015-07-05T09:27:36 < jadew> like 20 cm?

2015-07-05T09:27:47 < dongs> then no of course

2015-07-05T09:28:10 < dongs> no
2015-07-05T09:29:43 < jadew> well, then I guess there is a possibility that the video is for real, however slim
2015-07-05T09:29:56 < dongs> no way.
2015-07-05T09:30:18 < dongs> the only time that effect works on ym cam is if its like 2cm away from the front object
2015-07-05T09:30:42 < jadew> I just looked again at that video and it's pretty close
2015-07-05T09:30:52 < jadew> maybe less than 10 cm away
2015-07-05T09:31:10 < dongs> wind would have been blowing everywehre

2015-07-05T09:31:20 < jadew> good point
2015-07-05T09:31:30 < dongs> and theres no way to get a small quad to that kinda precise control

2015-07-05T10:11:26 < jpa-> yeah, and usually they only have a few steps

2015-07-05T10:37:55 < dongs> its never time for a macbook
2015-07-05T10:38:18 < Steffanx> Hi goodmorning dongs
2015-07-05T10:38:32 < jpa-> fortunately asus copied the fan placement from macbook
2015-07-05T10:39:02 < Steffanx> Also the silent fans and speed control?
2015-07-05T10:39:04 < jpa-> it's funny how it's very loud when listening at one angle (close to horizontal) but silent everywhere else
2015-07-05T10:39:10 < jpa-> seems so
2015-07-05T10:41:58 < jadew> I miss the days when CPUs only had a heatsink
2015-07-05T10:42:12 < jpa-> you can still buy such cpus
2015-07-05T10:42:21 < jpa-> they aren't even that slow anymore
2015-07-05T10:42:39 < jadew> I can't even imagine my room without the noise
2015-07-05T10:43:19 < jpa-> for me, ambient noise is a lot louder than the "silent" fan
2015-07-05T10:43:39 < jpa-> only when it spins up the hdd for some reason i can hear noise from computer
2015-07-05T10:43:56 < jadew> why is it so loud in there?
2015-07-05T10:44:08 < jadew> *so noisy
2015-07-05T10:44:18 < dongs> er r wat
2015-07-05T10:44:20 < jpa-> window is open and somewhat windy outside
2015-07-05T10:44:24 < dongs> my compouter is silent
2015-07-05T10:44:41 < dongs> intel stock fan is barely audible
2015-07-05T10:44:48 < dongs> i dont have anything else spinning in there
2015-07-05T10:45:31 < jadew> I have 3 big fans for the case
2015-07-05T10:45:42 < jadew> two medium ones for the heatsink
2015-07-05T10:46:07 < jadew> then there are at least 2 test instruments on my bench that have the PSU always on
2015-07-05T10:46:15 < jadew> and they have fans too
2015-07-05T10:46:27 < jadew> then there's the air purifier
2015-07-05T10:46:36 < jpa-> why are they always on?
2015-07-05T10:46:48 < jadew> to keep the OCXO ready
2015-07-05T10:47:10 < jadew> I don't care about it, but I got tired of always turning off the power strip

2015-07-05T14:06:18 < karlp> that marvel patent for aligning ip payloads sounds bogus, I could swear we were doing that at cisco in 2000 and before.

2015-07-05T16:07:56 < Roklobsta> i did some optimisation messing with gcc the other day.  doing X = (uint16_t)someuint32 generates a single opcode (extract halfword from word) instead of messing about with shifts and so on.
2015-07-05T16:12:03 < Roklobsta> decimad: what happens if you just do X = A * B where all are just uint32? even though the result is 64 bit you might get the upper 32 anyway, i think this maybe the case.
2015-07-05T16:13:14 < decimad> no, I don't think so
2015-07-05T16:13:34 < decimad> you would get 0 for values fitting into 32 bit
2015-07-05T16:16:16 < Roklobsta> i am sure making all types 32bit will do what you want.
2015-07-05T16:16:33 < Roklobsta> to get a 64 bit result you need to promide a and b to 64 bit first
2015-07-05T16:16:43 < Roklobsta> promote
2015-07-05T16:17:07 < decimad> yes, but uint32 * uint32 -> uint32 will result in the lower 32 bits, I bet
2015-07-05T16:17:13 < Roklobsta> nah
2015-07-05T16:17:24 < Roklobsta> that'd just be silly
2015-07-05T16:17:25 < decimad> So 8 * 8 would be 0?

2015-07-05T19:04:10 < zyp> what do you mean by logical errors?
2015-07-05T19:05:13 < decimad> well, errors that show op on every optimization level...
2015-07-05T19:05:54 < decimad> or rather: errors that don't depend on hardware specifics ;)
2015-07-05T19:06:27 < zyp> oh, like any errors that's not happening because you rely on undefined behavior

2015-07-05T19:09:49 < jpa-> slightly easier to debug, and not that much difference between optimization levels anyway

2015-07-05T19:11:06 < decimad> a friend of mine is programming everything in asm and keeps telling me what he can achieve with it and what I couldn't ;)
2015-07-05T19:11:32 < decimad> although he uses ethernet-to-serial ics and whatnot...
2015-07-05T19:11:37 < zyp> wasting lots of time?
2015-07-05T19:11:52 < decimad> he would argue that he's faster than me
2015-07-05T19:12:00 < decimad> there's no winning in these discussions
2015-07-05T19:12:14 < zyp> I would argue he's probably not
2015-07-05T19:13:21 < jpa-> he might actually be, but just because he doesn't do complex features
2015-07-05T19:14:07 < decimad> well, he didn't assume I was writing interrupt driven stuff just because I happen to program in C... so... many prejudices there
2015-07-05T19:15:12 < decimad> but then where he does have a point is the points where we need inline assembler... and I don't know if the compiler sometimes can't do register call optimizations for calling convention reasons... I wouldn't know
2015-07-05T19:15:36 < jpa-> what points would those be?
2015-07-05T19:15:53 < decimad> well, saturating arithmetics and stuff
2015-07-05T19:16:02 < jpa-> intrinsics work
2015-07-05T19:16:13 < jpa-> but yeah, those are often inline asm anyway
2015-07-05T19:16:24 < zyp> consider this: the assembler can't inline calls, the compiler can
2015-07-05T19:16:35 < decimad> but he's smarter than any compiler
2015-07-05T19:16:43 < decimad> he inlines it in his head
2015-07-05T19:17:35 < zyp> and I'd imagine that register allocation happens after call inlining, so you can get more efficient register usage from a compiler than by assembly
2015-07-05T19:17:39 < decimad> and since he doesn't need refactoring because his software is well written to begin with...
2015-07-05T19:18:22 < jpa-> i assume he doesn't have clients either?
2015-07-05T19:18:27 < jpa-> because clients always change requirements

2015-07-05T19:21:50 < jpa-> their custom arctan() really makes stuff fly!
2015-07-05T19:22:27 < decimad> so you couldnt write a custom arctan in c?

2015-07-06T02:56:37 < dongs> shruggin
2015-07-06T02:57:10 < dongs> how do these onetimepad things work that show a number when you turn them on
2015-07-06T02:57:20 < dongs> do they just have a PRNG with a known seed and some cryptohash on top of that?
2015-07-06T02:58:43 < BrainDamage> yes
2015-07-06T02:59:37 < BrainDamage> altough generally it's rather the date being fed to an asymmetric cypher
2015-07-06T03:00:00 < dongs> the number changes every press tho, so i doubt its d ate
2015-07-06T03:00:09 < BrainDamage> in that case there's a counter indeeed
2015-07-06T03:00:13 < dongs> and its unlikely any cheap rtc will be accurate enough for ~5 years lifetime of these things
2015-07-06T03:00:17 < BrainDamage> some are time based tough
2015-07-06T03:00:20 < BrainDamage> actually you can
2015-07-06T03:00:28 < BrainDamage> the rsa tokens are time based
2015-07-06T03:00:36 < BrainDamage> they generate a new id every 30s
2015-07-06T03:00:55 < dongs> so 30s is maybe within drift of a cheap rtc
2015-07-06T03:01:04 < BrainDamage> yep
2015-07-06T03:02:03 < BrainDamage> the one with a counter instead will accept all the sequence, and the n+1th will invalidate the nth
2015-07-06T03:02:17 < BrainDamage> to be more clear, if your token can generate the sequence 1 2 3 4
2015-07-06T03:02:26 < BrainDamage> the server will accept any of them
2015-07-06T03:02:31 < BrainDamage> but if you send say, 3
2015-07-06T03:02:40 < BrainDamage> then the tokens 1 and 2 will be considered spent
2015-07-06T03:03:32 < BrainDamage> this because the server has no way to know how many times you press the button and fail to submit a sequence
2015-07-06T03:03:46 < dongs> yeah if its prng or counter or wahtever maybe the server will know the "next" counter to expect, and if dumb user pressed button too many times, it will check the number entereed against current, current+1, current+n until it hits it
2015-07-06T03:03:56 < dongs> wonder how long it will "fast forward" before giving up tho
2015-07-06T03:08:20 < dongs> the shit i have changed number every press
2015-07-06T03:08:30 < dongs> doesnt matter how fast
2015-07-06T03:08:46 < dongs> hmm no wait

2015-07-06T03:08:54 < dongs> it changes and then if i keep bashing it wont
2015-07-06T03:09:09 < dongs> hah.
2015-07-06T03:09:15 < dongs> maybe this shit is rtc, too
2015-07-06T03:12:03 < BrainDamage> the counter based are typically a counter being fed to a symmetric cypher, oh and ofc, to make them stronger against cryptanalysis, both the rtc and the counter version get padded with random data
2015-07-06T03:12:35 < BrainDamage> if you have a "counter" type, and someone manages to steal one of the counters, the best thing to do is just generate a new one asap and send it
2015-07-06T03:12:41 < BrainDamage> since it'd invalidate the old one

2015-07-06T04:34:44 < upgrdman> anyone else seen circuits where optoisolaters were used just for level conversion (NOT isolation... same ground on both sides) ?
2015-07-06T04:44:05 < dongs> why not?
2015-07-06T04:44:12 < dongs> thats how i used them :)
2015-07-06T04:44:32 < dongs> optocouplers but yeah
2015-07-06T04:52:47 < upgrdman> just seemed weird. wouldn't purpose made level shifters be cheaper and faster?
2015-07-06T04:53:55 < upgrdman> well in my case, it kinda of makes sense because they use some for isolation, so using them in areas that just need level shifting would keep the BOM cleaner

2015-07-06T05:49:03 < dongs> upgrdman: i duno, where i used htem I had like 24-60V input signal
2015-07-06T05:49:08 < dongs> that I needed into logic level
2015-07-06T05:49:15 < upgrdman> oh
2015-07-06T05:49:27 < dongs> so i dont really see how i'd use a levelshifter for that shit
2015-07-06T05:56:08 < dongs> so i finally got my 5x 5TB toshiba shits here
2015-07-06T05:56:12 < dongs> in USB3 enclosures
2015-07-06T05:56:16 < dongs> need to figure ouw how to open the shit

2015-07-06T05:56:31 < dongs> this
2015-07-06T05:57:10 < dongs> So, to get a real feel for these, I pried them out of their cases and tested them out. (Prying open the case is a fairly simple matter. Start from the bottom and use about 3-4 gift cards to shim the cover and loosen the latches. Then, pull it apart with your bare hands, and the case should still be pretty much intact.
2015-07-06T05:59:03 < dongs> hmm nope
2015-07-06T06:04:13 < upgrdman> wat? no ethernet? fail.
2015-07-06T06:04:22 < dongs> wut
2015-07-06T06:04:28 < dongs> i bought them on sale for like $120
2015-07-06T06:04:33 < dongs> to pull drives out

2015-07-06T16:19:33 < dongs> I'm getting married in the UK on 14th August and was REALLY hoping to have some (unique) aerial footage and photos of my wedding; assuming certification is achieved can I ask you give your best estimate will I receive delivery in time ? (I'm backer #645 - SUPER EARLY BIRD FIRST EDITION BLACK ZANO). Anything that TG can do to enable delivery in time would be GREATLY appreciated :o).

2015-07-06T16:24:46 < decimad> I came to like  constexpr uint32 val = to_fixed<uint32, -28>(5.32423); too :)
2015-07-06T16:27:44 < decimad> Although that -28 isn't very intuitive... but "uint32 4.28" seems strange too... I could deduce the base type from 4.28 too, but then i'd have to say signed_fixed<4,28>/unsigned_fixed<4,28>.... hrmm

2015-07-07T00:19:36 < ambro718> yes I just figured this out :)
2015-07-07T00:19:38 < rkreis> i think the real solution involves changing the compiler/linker flags, i don't remember, the problem just disappeared for me
2015-07-07T00:19:56 < rkreis> -lopencm3_stm32l0 -lsupc++_nano -lstdc++_nano is what i use
2015-07-07T00:19:56 < ambro718> it only adds like ~20 bytes to RAM usage so I don't care
2015-07-07T00:20:37 < rkreis> i guess you could write an extern "C" void __dso_handle(); too :)\
2015-07-07T00:21:20 < ambro718> huh? it's supposed to be a void* not a function, I think
2015-07-07T00:22:09 < ambro718> I have:  -nostartfiles -Wl,--gc-sections --specs=nano.specs   with a platform-specific linker script
2015-07-07T00:23:37 < rkreis> i don't know, i wouldn't expect it to be used at all, so by that logic it doesn't matter and making it a function could save some ram :D
2015-07-07T00:24:13 < ambro718> I think it gets passed to some internal function in the libc that ends up calling all the functions for static initialization (constructor calls)
2015-07-07T00:24:18 < rkreis> also, interesting, i use nosys.specs instead of nano.specs (and various other flags scattered over my once-readable makefile)
2015-07-07T00:25:00 < rkreis> ah, i thought it's only used for dynamic linking
2015-07-07T00:25:19 < ambro718> it probably is but the static init stuff seems to be passing it around for some reason
2015-07-07T00:25:34 < ambro718> so the least it should be dereferencable ;)
2015-07-07T00:25:59 < rkreis> Lux, probably you're missing an extern "C"" and your handler is basically ignored
2015-07-07T00:26:45 < ambro718> or not - it should fail to link then
2015-07-07T00:26:49 < rkreis> hm, objdump doesn't find anything at all, maybe there's no static initialization, or the optimizer killed it :)
2015-07-07T00:27:16 < ambro718> rkreis:   struct Foo { Foo(){} }; Foo foo;

2015-07-07T00:27:38 < ambro718> it must result in some static init code in the object/asm. If not add a printf into the constructor.
2015-07-07T00:28:01 < rkreis> well, i don't remember if i'm using that feature, let's see
2015-07-07T00:31:08 < rkreis> ambro718, still no luck
2015-07-07T00:31:38 < rkreis> even with -O0 and a struct that should definitely be initialized
2015-07-07T00:32:28 < rkreis> something made my __dso_handler issues magically disappear :)

2015-07-07T05:38:48 < dongs> maybe even better than 3/4
2015-07-07T05:55:36 < zyp> nice
2015-07-07T05:58:26 < aandrew> dongs: that's your driver?
2015-07-07T05:58:37 < dongs> yeah
2015-07-07T05:58:41 < aandrew> nice
2015-07-07T05:59:02 < aandrew> so you're just passing the DP signals over, what's the IC in the upper right (on the actual board driving the display)
2015-07-07T05:59:23 < dongs> er its stm32 doing the job of attiny23
2015-07-07T05:59:30 < aandrew> lol
2015-07-07T06:00:09 < dongs> its another fucking vertical panel tho 1536x2048, so intel trash gfx will probly not w ork wiht it either
2015-07-07T06:00:16 < dongs> just like the 7.9" mini one
2015-07-07T06:00:47 < aandrew> what, intel gfx won't rotate?
2015-07-07T06:01:17 < dongs> not rotate
2015-07-07T06:01:21 < dongs> it trips the driver
2015-07-07T06:01:25 < dongs> like wont even enable it
2015-07-07T06:01:42 < dongs> probably front/back porch stuff is out of spec
2015-07-07T06:06:03 < aandrew> hm
2015-07-07T06:06:26 < aandrew> DP is unidirectional though isn't it? doesn't it figureo out what the display wants with something equivalent to EDID?
2015-07-07T06:07:07 < dongs> its bidirectional, wiht dpaux stuff.
2015-07-07T06:07:12 < dongs> it knows what the panel wants
2015-07-07T06:07:13 < aandrew> hm, shitty
2015-07-07T06:07:16 < dongs> it just doesnt wanna display it.
2015-07-07T06:07:30 < dongs> might be possible to figure out what the issue is wiht a lunix intel driver
2015-07-07T06:07:34 < dongs> to see waht eactly it doedsdns like

2015-07-07T08:13:14 < dongs> The displays on previous generations of iPad used three separate components. iPad Air 2 changes all that, combining those three layers into just one. This eliminates gaps between layers, along with the internal re.ectance caused by those gaps. The result? Colors are richer, contrast is greater, and images are sharper and more vivid.

2015-07-07T11:12:15 < dongs> That photo doesn't look bad considering it's taken inside in bad light. Any chance of uploading the full JPEG? I'd like to put it through Lightroom and see what can be done with it.

2015-07-07T11:22:44 < dongs> Doing some speed tests, we can restart Zano from the app, install an entirely fresh build of the operating system and have Zano up and running again ready for video and flight within 6.5 seconds. All you see is a fast flickering of landing lights to show a new OS is being installed and literally seconds later, its up and running with the latest OS.
2015-07-07T11:22:51 < scrts_w> seems like interpolated minimum 4 times
2015-07-07T11:22:59 < dongs> completely useful statistic
2015-07-07T11:31:46 < decimad> is their firmware so bad they optimize updating it?
2015-07-07T11:32:46 < jpa-> fw upgrade is the only thing that works
2015-07-07T11:36:24 < decimad> So I have this vector oriented control handy, but now I need to inspect the vectors for the bit that flips and distribute to the timer comparators accordingly... why would the stm32 timers not be able to have configurable u8/16/u32 outputs? :(

2015-07-07T11:38:42 < dongs> we begged dell&co for some free shit
2015-07-07T11:38:45 < dongs> and installed jewbunto on it

2015-07-07T11:38:58 < dongs> with out shit on it
2015-07-07T11:39:09 < dongs> so the first thing users will do is format and install windows 2012 server
2015-07-07T11:39:29 < dongs> also yeah, who the fuck uses ubunto on anything serious

2015-07-07T12:55:57 < dongs> Regarding the photo I uploaded. It is actually a 960*720 frame from the video feed to the app so the compression is much higher than you will get from the photo mode. I have a bug in the photo mode that is causing only the first 40kb of the photo to be sent so rather than waiting until I fixed that bug (on my list today) I thought I would post a video frame instead.

2015-07-07T13:05:45 < dongs> but the quality is garbage
2015-07-07T13:06:00 < dongs> and they're windowing the sensor for 960x720 instead of using full 5mp and letting ISP do the scaling
2015-07-07T13:06:08 < dongs> so the quality will continue being pure shit
2015-07-07T13:06:57 < dongs> original image was 29k, he said "reuploading to forum recompressed it"

2015-07-07T14:16:48 < dongs> probably the best zano could possibly hope to have is around that.

2015-07-07T14:21:31 < decimad> the motor cases and rotors need painting too!
2015-07-07T14:22:11 < decimad> also it would have to be painted blue from below... or maybe multiple weather casings...
2015-07-07T14:22:46 < decimad> the edges need to be sharp as well ;)

2015-07-07T15:48:14 < jpa-> decimad: yeah, well, using free stuff for commercial products, not surprising there are a few restrictions
2015-07-07T15:48:25 < decimad> how do you opensource your stuff without gpl3 now?
2015-07-07T15:48:46 < jpa-> 12:55:57 < dongs> Regarding the photo I uploaded. It is actually a 960*720 frame from the  video feed to the app so the compression is much higher than you will get  from the photo mode. I have a bug in the photo mode that is causing only  the first 40kb of the photo to be sent so rather than waiting until I  fixed that bug (on my list today) I thought I would post a video frame  instead.
2015-07-07T15:48:50 < Laurenceb> is it necessary to disable a usart before reconfiguring it?

2015-07-07T15:49:53 < jpa-> decimad: by just including chibios, chibios being gplv3, your code something more permissive, everything becomes gplv3 when linked?
2015-07-07T15:50:23 < decimad> that would be my understanding... correct me if I'm wrong
2015-07-07T15:50:43 < jpa-> but yeah, ok, it can suck if you need gplv2 libraries etc.
2015-07-07T15:52:02 < decimad> so in the end, it was free beta testing from folks until chibi 3.0 hehe
2015-07-07T15:53:17 < jpa-> i wouldn't call it that, it's still fully available with gpl license anyway
2015-07-07T15:53:40 < jpa-> not like they went to full-retard license like some projects
2015-07-07T15:54:06 < decimad> but there's the commercial license that profits from a large testing audience, which is larger if you can use it for closed source stuff

2015-07-07T15:54:38 < decimad> or for more permissive stuff really
2015-07-07T15:54:58 < jpa-> but if you have some use case that is not met by chibios licensing, perhaps contact them and try to work it out?
2015-07-07T15:55:19 < decimad> my use case it to not put my stuff to gpl3, but apache or something
2015-07-07T15:55:25 < decimad> *is
2015-07-07T15:55:55 < jpa-> so you'd like an exception that linking with "open source code under any OSI-approved license" is allowed?
2015-07-07T15:55:59 < jpa-> maybe they'd do that
2015-07-07T15:56:35 < decimad> but maybe I'm wrong with my understanding, in the end I'll ask I guess
2015-07-07T15:57:24 < decimad> callback mechanism across threads sucks... hrmmmm
2015-07-07T16:00:35 < Laurenceb> is it necessary to disable a usart before reconfiguring it?
2015-07-07T16:01:08 < decimad> I wouldn't know, but I guess it would be cleaner anyways
2015-07-07T16:01:52 < decimad> consider input buffers being filled with scrap while non-atomically reconfiguring

2015-07-07T20:10:03 < zyp> you're doing something strange
2015-07-07T20:10:17 < ambro718> Broken like, simple code may work, but the whole application may crash or behave unexpectedly.
2015-07-07T20:10:30 < ambro718> zyp: No way!
2015-07-07T20:10:44 < zyp> impossible to guess
2015-07-07T20:11:43 < zyp> if you have a reproducible case, trap the bug in a debugger and trace it back to which instructions are causing it, then figure out why the compiler produces said instructions
2015-07-07T20:13:01 < ambro718> yes I'll probably try that, though it doesn't crash one the one platform where I have debug capability, only behaves wrong :S

2015-07-07T21:47:29 < PaulFertser> aandrew: semihosting is the same, no matter if you use JTAG or SWD, it's done with a software breakpoint and debugger on host handles that.
2015-07-07T21:48:01 < aandrew> ok. So you're saying that directly spewing data out SWO can be nonblocking?
2015-07-07T21:48:10 < PaulFertser> aandrew: ITM is going via TPIU which is attached to a trace port, and if you're using trace port of width 1 bit it's called SWO. So it's a dedicated channel.
2015-07-07T21:48:11 < aandrew> i.e. not within the semihosting environment
2015-07-07T21:48:24 < aandrew> right, right. I was reading a bit about this
2015-07-07T21:48:52 < aandrew> how you can emit arbitrary data that is essentially "free" from a CPU time perspective
2015-07-07T21:49:17 < PaulFertser> It's not free, but you can do it without blocking.

2015-07-08T16:52:56 < Getty> ARGHL.............. since the reordering of the network startup the webserver gives back "connection refused" and this kicks of all the timeout

2015-07-08T16:59:23 < Getty> uh, thats really sexy
2015-07-08T16:59:52 < Getty> but how someone can actually make those? you cant 3d print it i would it, and painting those things is still a challenge, or?
2015-07-08T17:00:00 < karlp> just buy enough
2015-07-08T17:00:15 < Getty> hehe no i mean, if you want to add this info on your own hardware for your own stuff
2015-07-08T17:00:17 < karlp> I'm sure samtec et all will print for you if you ask.
2015-07-08T17:00:21 < Getty> and dont have a big factory to produce those ;)

2015-07-08T17:31:24 < Taxman> my code works with -O0, but with -M2 it calls WWDG_IRQHandler
2015-07-08T17:31:50 < Taxman> has anyone experienced this problem, too?
2015-07-08T17:31:54 < Rickta59> maybe put a pragma around your interrupt code and the code that calls it
2015-07-08T17:32:07 < Rickta59> the pragma to disable optimization for things that aren't working
2015-07-08T17:32:48 < Rickta59> http://stackoverflow.com/questions/2219829/how-to-prevent-gcc-optimizing-some-statements-in-c
2015-07-08T17:33:38 < PaulFertser> That'd be usually a wrong way to fix it.
2015-07-08T17:33:53 < Rickta59> agreeded
2015-07-08T17:34:03 < PaulFertser> Better way imho is to work with -O2 or -Os right from the beginning.
2015-07-08T17:34:24 < Rickta59> that is what i do
2015-07-08T17:34:32 < Taxman> well the problem seems to be caused by SysTick_Handler()
2015-07-08T17:34:47 < Rickta59> are you using a global that isn't marked volatile?
2015-07-08T17:35:26 < Taxman> you mean a global used in the isr?

2015-07-08T17:37:04 < Taxman> SysTick_Handler() is using some local variables declared as static
2015-07-08T17:38:42 < Rickta59> if you increment a varible in the systick and it isn't marked volatile .. then the optimizer will probably get rid of it
2015-07-08T17:38:54 < Rickta59> you should generate the code and then dump it using objdump
2015-07-08T17:39:02 < Rickta59> and look at what it actually generates

2015-07-08T17:40:15 < Taxman> Rickta59: You mean a global variable
2015-07-08T17:40:18 < Taxman> right?
2015-07-08T17:40:27 < Rickta59> or a file local global

2015-07-08T17:51:28 < Getty> so the question is now, if you have the heatwave now we had, or if you have the upcoming heatwave we will get next weekend
2015-07-08T17:51:37 < Getty> 8-)
2015-07-08T17:54:37 < Taxman> now my systick handler ISR just contains a return: SysTick_Handler() { return; }
2015-07-08T17:55:18 < Taxman> and the WWDG_IRQHandler is called again, if SysTick_Config(SYSTEMCORECLOCK / 1000);
2015-07-08T17:55:33 < Taxman> if not enabled // SysTick_Config(SYSTEMCORECLOCK / 1000);
2015-07-08T17:55:51 < Taxman> then no WWDG_IRQHandler is called
2015-07-08T17:56:09 < Rickta59> are you running out of flash?
2015-07-08T17:56:18 < Rickta59> if not maybe you should just leave it unoptimized
2015-07-08T17:56:42 < Taxman> maybe later, -O2 is much faster
2015-07-08T17:56:50 < Taxman> i expect that -O2 works
2015-07-08T17:57:24 < Rickta59> things go fast when there is no code

2015-07-08T20:13:28 < ambro718> What "TRACECLKIN_freq" should I specify in openocd's "tpiu config"? I'm using the F4-Discovery.
2015-07-08T20:14:16 < jpa-> it's most likely the same as your cpu core clock
2015-07-08T20:14:32 < jpa-> so 168MHz typically for F4, though your code might configure something else
2015-07-08T20:14:54 < ambro718> yes I use 168, because I need USB
2015-07-08T20:18:10 < ambro718> what do I need to specify in the tpiu command? It has this sync/manchester/uart stuff that I don't know what to do with.
2015-07-08T20:18:28 < ambro718> tpiu config (disable | ((external | internal <filename>) (sync <port width> |               ((manchester | uart) <formatter enable>)) <TRACECLKIN freq>               [<trace freq>]))
2015-07-08T20:19:13 < jpa-> what are you capturing the trace with?
2015-07-08T20:19:27 < ambro718> the integrating st-link2 chip
2015-07-08T20:19:33 < ambro718> *integrated
2015-07-08T20:19:33 < jpa-> it's uart then

2015-07-08T22:19:59 < Rickta59> you have to make a configuration file or alternatively provide the right stuff on the command line

2015-07-08T22:35:16 < synic> yikes
2015-07-08T22:38:51 < owl-v-> I received a SIGTRAP message from my board. Is this same as 'halt'?
2015-07-08T22:44:08 < owl-v-> when is the right time to jump from m4 to m7 ?
2015-07-08T22:44:38 < Tectu> so many questions, so little answers
2015-07-08T22:45:21 < Tectu> the right time is when your m4 does not get the job done. But then upgrading to an m7 would probably only yell very little performance improvements
2015-07-08T22:46:36 < karlp> ambro718: you don't want to print it to stdout, because you have 32 channels of it, and no-one said it had to be character data either.
2015-07-08T22:47:01 < karlp> Tectu: stop making assumptions and telling people, stlink works just fine with other chips.
2015-07-08T22:47:34 < ambro718> karlp: all I need is debug output from printf, I currently have no use for other kind of data
2015-07-08T22:48:11 < karlp> good fo ryou :) don't spam mystdout with binary data just because you like it like that :)
2015-07-08T22:48:41 < Tectu> karlp, I mentioned that I have no idea.
2015-07-08T22:49:04 < karlp> the way I reocmmend is tail -f swodump.bin | swodec --filter-inst <itm stimulus number> --dump-inst
2015-07-08T22:49:14 < karlp> Tectu: then you said but you thought it had checks.
2015-07-08T22:49:37 < owl-v-> eh? -> in procedure 'ocd_bouncer'
2015-07-08T22:50:05 < Tectu> karlp,   s/"am pretty sure"/assume    can you stop crying now and move on?
2015-07-08T22:50:58 < ambro718> karlp:  I improved my code to send multiple bytes in a packet, and now I think there's a bit less of dropped data. I also used https://git.zapb.de/swodec.git/ to decode the stream.
2015-07-08T22:51:34 < karlp> that or the itmdump, as you got from #openocd
2015-07-08T22:51:53 < karlp> it's worth remembering that it's a multi channel stream :)
2015-07-08T22:52:02 < karlp> you can use it as much more than just another printf console :)
2015-07-08T22:52:23 < ambro718> I'll keep that in mind :)
2015-07-08T22:54:56 < karlp> you can get exception tracing, a stream with just the value you wanted to pritnf, including timestamping, all sorts of things without calling printf
2015-07-08T22:56:32 < karlp> I feel that your checking of both ITM_TCR -and_ ITM_TER is excessive, if TCR is disallowed, the writes have no effect, I just do the check on TER outside the while loop too, I don't really see a lot of need for potentially being able to turn on trace in the middle of a write() call.
2015-07-08T22:57:32 < karlp> hrm, I lied, I thought I did that :)
2015-07-08T22:57:37 < ambro718> ah okay. I really had no idea what the code was doing, I just saw it on some random site :)
2015-07-08T22:57:46 < karlp> https://pastee.org/fgcdb
2015-07-08T22:58:28 < karlp> if you don't do the while check on the fifo ready, you can have much lower impact on your code, or, more predictable impacts at least
2015-07-08T22:58:41 < karlp> you will see "overflow" in the decoded otuput if you lose data anyway
2015-07-08T22:58:54 < karlp> (if you lost it in the core, if your debugger loses some, that's just gone)
2015-07-08T22:59:10 < ambro718> you mean, I can just delete the entire check?
2015-07-08T22:59:17 < ambro718> if ((ITM->TCR & ITM_TCR_ITMENA_Msk) == 0 || (ITM->TER & ((uint32_t)1 << ITM_STIMULUS_PORT)) == 0) {
2015-07-08T22:59:18 < karlp> for TCR? yeah, toss it
2015-07-08T22:59:35 < karlp> the TER is checking wheter the stimulus port is enabled
2015-07-08T22:59:43 < karlp> TCR is checking whether you have permissions to write to it
2015-07-08T22:59:57 < ambro718> TER check is still needed then?
2015-07-08T23:03:24 < karlp> if you do the while() on the port being ready, you need to check it
2015-07-08T23:03:31 < karlp> if you just try the write, you don't need to care.
2015-07-08T23:03:39 < karlp> if it's disabled, the while() will never finish
2015-07-08T23:05:32 < karlp> http://paste.fedoraproject.org/241595/43638586/ will give you a "dwt_pc_sampling" command in openocd too, which swodec can decode to addresses, and a bit of arm-none-eabi-addr2line can turn back into code coverage hints with a bit of fiddling.

2015-07-09T02:10:59 < Tectu> zyp, I know what cache is. Trying to figure out what SCB stands for
2015-07-09T02:11:11 < zyp> system control block, it's one of the cortex-m core peripherals
2015-07-09T02:11:28 < zyp> it's documented in the m7 RM, not the stm32 RM
2015-07-09T02:11:30 < Tectu> zyp, thank you sir. So nothing I will find in the RM
2015-07-09T02:11:38 < Tectu> zyp, thank you.
2015-07-09T02:11:40 < Laurenceb_> yeah ST RM doesnt cover the core
2015-07-09T02:11:44 < zyp> you'll just need to read the right RM ;)
2015-07-09T02:12:01 < Tectu> zyp, I asume enabled vs. disabled CPU cache is just a question of performance - the program will run the same? Or does this affect other things too?
2015-07-09T02:12:07 < Tectu> zyp, hehe

2015-07-09T02:13:47 < zyp> depends
2015-07-09T02:15:02 < zyp> I'm not too familiar with working with cache, so I can't really talk about specifics
2015-07-09T02:15:46 -!- perillamint [~perillami@61.72.142.236] has joined ##stm32
2015-07-09T02:16:26 < zyp> usually you want cache for performance reasons, but it need to be managed right
2015-07-09T02:18:24 < zyp> on a single cpu system it's probably not so hard, but on a multicpu system there's a lot of shit involved to make sure that when one cpu edits a memory area, no other cpu has an old copy of that area cached
2015-07-09T02:18:38 < zyp> hmm, this of course also applies to a single cpu system and dma
2015-07-09T02:19:49 < zyp> so yeah, one good argument for turning off cache is to rule out that whatever bug you are tracing down is not caused by cache incoherency
2015-07-09T02:20:36 < zyp> read up on https://en.wikipedia.org/wiki/Cache_coherence if you're not familiar with cache coherency

2015-07-09T16:37:31 < Laurenceb> apparently thats what spacex use
2015-07-09T16:38:03 < decimad> So how would I calculate (a1 + 10^9*b1) / (a2+10^9 * b2) in fixed point? grml
2015-07-09T16:38:12 < karlp> Laurenceb: what price?
2015-07-09T16:38:20 < Laurenceb> $395
2015-07-09T16:38:58 < decimad> 10^-9 i mean ;)

2015-07-10T01:00:24 < decimad> gnarf, this raspberry packet timestamping can be off by +-50us in spikes...
2015-07-10T01:01:02 < decimad> do you know a simple outlier filter?
2015-07-10T01:21:37 < Laurenceb_> raspberry pi?
2015-07-10T01:21:55 < Laurenceb_> I should know a filter....
2015-07-10T01:22:09 < Laurenceb_> you could do a rolling comparison of three samples
2015-07-10T01:23:57 < decimad> yes raspberyy pi, hrmmm, I don't think 3 samples are enough for this... anyways, I'll be doing a rolling 8 sample average... though still it would be nice not to disturb it with spikes...
2015-07-10T01:24:19 < Laurenceb_> this is on ethernet?
2015-07-10T01:24:25 < decimad> yes
2015-07-10T01:24:28 < Laurenceb_> wtf
2015-07-10T01:24:36 < Laurenceb_> how does it work so well :P
2015-07-10T01:24:44 < Laurenceb_> its usb ethernet
2015-07-10T01:25:41 < decimad> well, it's hardware timestamping on one side... and raspberry software timestamping on the other
2015-07-10T01:25:50 < Laurenceb_> ok
2015-07-10T01:25:55 < decimad> that's why it's so bad :(
2015-07-10T01:26:33 < Laurenceb_> so good :P
2015-07-10T01:26:39 < Laurenceb_> considering how lame it is
2015-07-10T01:26:42 < decimad> but I had this raspberry flying around... I should really buy another stm32f4 board...
2015-07-10T01:28:05 < decimad> hehe, the clocks diverged by -3 ms in half an hour... how lame are these crystals...
2015-07-10T01:28:24 < Laurenceb_> wut
2015-07-10T01:28:44 < Laurenceb_> thats very good
2015-07-10T01:28:51 < Laurenceb_> 1.6ppm
2015-07-10T01:29:08 < decimad> well, it's already adjusted for a few ppb in software
2015-07-10T01:29:25 < decimad> the 3 ms is what came on top of it... the control loop is not yet closed
2015-07-10T01:29:40 < Laurenceb_> interesting
2015-07-10T01:29:48 < Laurenceb_> how do you do software correction?
2015-07-10T01:30:02 < Laurenceb_> is this the linux utc time tracking stuff?
2015-07-10T01:30:17 < Laurenceb_> iirc I run that on my servers
2015-07-10T01:30:34 < decimad> I don't really... I control the stm32f4 ptp hardware clock... basically just two counters...
2015-07-10T01:30:44 < Laurenceb_> im confused
2015-07-10T01:30:54 < Laurenceb_> Rpi <-> stm32f4   ?
2015-07-10T01:30:57 < decimad> yea
2015-07-10T01:30:58 < Laurenceb_> via ethernet
2015-07-10T01:30:59 < Laurenceb_> ah
2015-07-10T01:31:13 < Laurenceb_> so you are setting the hardware rtc on the stm32?
2015-07-10T01:31:42 < decimad> Not the rtc... the dedicated clock in the ethernet mac
2015-07-10T01:31:52 < Laurenceb_> oh
2015-07-10T01:31:58 < Laurenceb_> I need to RTFM
2015-07-10T01:32:29 < decimad> it's just two counters with overflowing really...
2015-07-10T01:32:46 < decimad> need to setup increments so overflows happen in right intervals
2015-07-10T01:33:26 < decimad> but the good thing is, it can timestamp packets on arrival... no jitter on stm32 side...

2015-07-10T01:34:10 < Laurenceb_> ah
2015-07-10T01:34:34 < Laurenceb_> so yeah, the jitter is likely to be due to the USB timing jitter on the Rpi
2015-07-10T01:35:02 < decimad> yup... don't think I can improve on that... sad... :(
2015-07-10T01:35:41 < decimad> anyways, staying within 10us is well enough for my applications... ;)
2015-07-10T01:36:33 < Laurenceb_> what is your application?
2015-07-10T01:36:40 < Laurenceb_> you work for Spacex?
2015-07-10T01:36:42 < Laurenceb_>  /jk
2015-07-10T01:37:24 < Laurenceb_> apparently they cant work out wtf is going on with their embedded ethernet timing - they are trying to debug their CRS-7 failure
2015-07-10T01:38:30 < decimad> nah, I want to have distributed servo controls... so I can just send like 100ms path buffers from the client to all drives... so they must not diverge in time...
2015-07-10T01:40:54 < decimad> makes for simpler software was my thinking... I don't know how people really tackle this ;)

2015-07-10T07:26:26 < dongs> at least I only paid $105 for it shipped, so hopefully they lost money from me
2015-07-10T07:27:52 < upgrdman> neat
2015-07-10T07:28:07 < upgrdman> i wonder if the sony chip is an ASIC or just a rebranded FPGA
2015-07-10T07:28:40 < dongs> it is probably some sony custom silicon
2015-07-10T07:29:02 < dongs> i also suspect this board can be populated for other functions
2015-07-10T07:29:05 < dongs> its probably from a BD player or so
2015-07-10T07:29:15 < dongs> cuz there's spots for sata connectors, etc
2015-07-10T07:30:11 < dongs> er, i mean, can be used in a bd player

2015-07-10T08:04:03 < dongs> The difference between IBM and INTEL is that when INTEL develops a new technology, they can manufacture with it and make money. When IBM develops a new technology, they get one chip to work. It's a start, but the real trick is to also have good die yield and make money with the right targeted product.

2015-07-10T10:28:03 < zyp> if you can reconstruct from the remaining data, you can drop the data you won't need

2015-07-10T13:15:23 < pointertonullval> jpa-, tried both without any resultr.. There are a lot of hardware informations but not so much for software
2015-07-10T13:15:39 < pointertonullval> also in the ez.analoc.com forum
2015-07-10T13:15:51 < pointertonullval> neither in github
2015-07-10T13:16:31 < jpa-> https://github.com/Xilinx/linux-xlnx/blob/master/drivers/media/i2c/adv7604.c ?
2015-07-10T13:17:48 < dongs> so let me repeat from the official camera module documentation: "supporting multiple output formats".
2015-07-10T13:17:51 < dongs> That means the camera module picks the 1080p raw stream from the sensor, does a some processing that discards some pixels and some frames, that way creating two streams, a 1080p30FPS and another one that is much lighter for WiFi transmission and outputs to Zano those two separate streams.
2015-07-10T13:17:56 < decimad> okay... +- 5 us... mission accomplished
2015-07-10T13:18:12 < dongs> err
2015-07-10T13:18:13 < dongs> pointertonullval: hi
2015-07-10T13:18:21 < dongs> i have 7611 on a bunch of boards.
2015-07-10T13:18:29 < dongs> how it works, is you use TI's tool to create i2c script
2015-07-10T13:18:35 < jpa-> pointertonullval: and the "HDMI Receiver Library API Source Code" from manufacturer also looks like software to me
2015-07-10T13:18:41 < dongs> set up all the stuff in there, and it outputs the register settings for you
2015-07-10T13:18:52 < dongs> pointertonullval: https://ez.analog.com/docs/DOC-9146
2015-07-10T13:18:59 < dongs> jpa-: fuck lunix trash. vendor has proper tools to do it.
2015-07-10T13:19:22 < dongs> pointertonullval: install that, choose adv7611, configure your settings in gui, output i2c config script in your chosen format.
2015-07-10T13:22:47 < DanteA> And fuck with it again and again, if resulting script doesn't working
2015-07-10T13:22:56 < DanteA> Nice tip
2015-07-10T13:23:05 < dongs> there's not much to fuck up
2015-07-10T13:23:22 < dongs> you need to generate EDID, init ~20 registers, and youre done
2015-07-10T13:23:30 < dongs> watch for interrupt for HPD and shit, but thats optional
2015-07-10T13:24:31 < DanteA> There is always exists what to fuck up in any black box, if something isn't working properly.
2015-07-10T13:24:53 < dongs> would believe if the chip didn't have a comprehensive reference manual for all registers
2015-07-10T13:25:32 < dongs> i mean,  wiht the RM you can basically write your own init script because it tells you wat to do
2015-07-10T13:25:44 < dongs> but if you don't want to fuckup/waste time, aves3 will just output it ready to copypaste.
2015-07-10T13:25:47 < dongs> everyone wins
2015-07-10T13:26:03 < dongs> and there's another analog tool that will generate all sorts of EDID stuff
2015-07-10T13:26:31 < dongs> https://ez.analog.com/docs/DOC-2143 this
2015-07-10T13:27:03 < DanteA> Spending a time, if black box didn't working...
2015-07-10T13:27:04 < dongs> those 2 things and adv7611 is super easy
2015-07-10T13:27:30 < dongs> DanteA, listen. I'm quite disgusted by your non-apology and fakery. I have removed you from all my social contacts. Your naivete is not worth my time. There are a lot of better tech experts out there, experts that surely pay more attention about diversity than YOU DO.
2015-07-10T13:27:54 < dongs> pointertonullval: what are you doing with adv7611 anyway.

2015-07-10T13:32:13 < dongs> pointertonullval: its doable with horizontal split. how are you planning to do vertical?
2015-07-10T13:32:19 < dongs> Tectu: definitely

2015-07-10T13:32:52 < dongs> pointertonullval: also, with 7611, you probably won't be able to split anytrhing bigger than 1920x1080 since its limited to 165mhz pixel clock
2015-07-10T13:32:59 < scrts_w> dongs: and the interface to the panel is... eDP?
2015-07-10T13:33:11 < dongs> scrts_w: lvds on that particular board
2015-07-10T13:33:37 < dongs> but i made it modular so it can actually be edp or wahtever.
2015-07-10T13:33:43 < scrts_w> so the PC sees a single monitor with 2x horizontal resolution?
2015-07-10T13:33:46 < dongs> yes
2015-07-10T13:33:52 < scrts_w> cool:)
2015-07-10T13:34:18 < dongs> the vertical noise was my awful powersuply decoupling which I already fixed in v2, this is an ancient pic
2015-07-10T13:34:29 < dongs> those lines are like harmonics off 1.2mhz switching reg
2015-07-10T13:34:30 < dongs> huhuh
2015-07-10T13:34:34 < Tectu> dongs u sell those?
2015-07-10T13:34:40 < dongs> nah, its a customer proj
2015-07-10T13:34:56 < dongs> i might make a 4k splitting one tho
2015-07-10T13:34:58 < Tectu> no affro branding then?
2015-07-10T13:35:01 < scrts_w> so the input is HDMI or DP?
2015-07-10T13:35:06 < dongs> 3840x1080 -> 2x screens

2015-07-10T13:35:29 < dongs> Tectu: just kawaii annimeay figures
2015-07-10T13:35:48 < dongs> i duno of anything that';ll do vertical split like that tho.
2015-07-10T13:35:51 < dongs> horizontal is easy
2015-07-10T13:35:57 < scrts_w> a bit annoying thing is that when you maximize window, it would do across all screens :)
2015-07-10T13:36:02 < dongs> heh
2015-07-10T13:36:48 < Tectu> scrts_w, you can go fullscreen on just one screen buy dragging it at the outermost edge. windows makes it take up 50% horizontal and 100% vertical space then
2015-07-10T13:36:49 < decimad> hehe, measuring temperature by drift seems to work okay ;)
2015-07-10T13:37:03 < dongs> Tectu: first thing i disable on win8.x install
2015-07-10T13:37:16 < dongs> absolutely rage inducing
2015-07-10T13:38:14  * scrts_w is still on Win7 on all PCs
2015-07-10T13:38:40 < dongs> sorry to hear that
2015-07-10T13:38:47 < scrts_w> works fine
2015-07-10T13:38:54 < scrts_w> dunno why to change it
2015-07-10T13:39:12 < Tectu> dongs, wouldnt even know where to disable it. i never did it accidentially
2015-07-10T13:39:30 < dongs> tectu, it *always* triggers for me and its very annoying.
2015-07-10T13:39:42 < dongs> its the whole "make my mouse easier to use" thing in assistance control panel
2015-07-10T13:39:51 < dongs> the worst one is
2015-07-10T13:39:56 < dongs> you click on title bar
2015-07-10T13:39:58 < dongs> and shake that window
2015-07-10T13:40:01 < dongs> try it :)
2015-07-10T13:40:04 < dongs> click = click+hold
2015-07-10T13:40:54 < dongs> that one is 100000x more rage inducing than winkey-d because if you accidentally hit win-d you can undo by hitting it again as long as y ou didnt fuck with other windows
2015-07-10T13:41:04 < dongs> but the shake effect fucks all the z-order for all open windows and you can't undo
2015-07-10T13:41:05 < Tectu> dongs, oooh no I wont do that one. That one rages me whenever it happens too
2015-07-10T13:41:11 < Tectu> dongs, but it only happens once a month or so
2015-07-10T13:41:24 < Tectu> but the rage lasts for around three weeks
2015-07-10T13:41:29 < dongs> yep.
2015-07-10T13:41:36 < dongs> its disabled in same place where auto-arrange shit happens.
2015-07-10T13:41:38 < dongs> same setting.
2015-07-10T13:41:45 < Tectu> dongs, checking that out now.
2015-07-10T13:41:52 < Tectu> dongs, I never bothered configuring crap
2015-07-10T13:42:27 < jpa-> it sucks that you cannot disable them separately
2015-07-10T13:42:41 < dongs> no worries, theres nothing of value in those
2015-07-10T13:42:43 < jpa-> snap to edge is somewhat useful (while winkey+arrows is easier)
2015-07-10T13:43:22 < dongs> oh fuck off.
2015-07-10T13:43:32 < dongs> turned it on to check what that does
2015-07-10T13:43:36 < dongs> no thanks :)
2015-07-10T13:43:49 < Tectu> dongs, there is also  ¨Make it easier to see mouse¨
2015-07-10T13:44:03 < jpa-> and "simulate malfunctioning keyboard"
2015-07-10T13:44:11 < dongs> no the one you want is 'prevent windows from being automatically arranged when moved to the edge of screen"
2015-07-10T13:44:26 < dongs> under make the mouse easier to use.
2015-07-10T13:44:34 < dongs> that disables all those auto-arrange/shake/etc shits
2015-07-10T13:44:36 < dongs> and winkey=arrows
2015-07-10T13:44:43 < Tectu> dongs, is that in the crappy new win8 settings menu only or also in the control panel?
2015-07-10T13:44:54 < dongs> win-r-control

2015-07-10T13:59:16 < dongs> 4 streams of 24bit rgb = 24bits+pixclk+hsync+vsync+de = 28bits * 4 = 112 and your chip only has 64 i/o pins
2015-07-10T14:00:23 < scrts_w> pointertonullval: go for max10
2015-07-10T14:00:24 < dongs> (and thats not considering the input 28bits from hdmi receiver.

2015-07-10T14:48:08 < zyp> what's that supposed to be?
2015-07-10T14:48:14 < dongs> err what
2015-07-10T14:48:18 < dongs> youre going to use a shift register?
2015-07-10T14:48:46 < dongs> 800x480 @60p is 26mhz pixclk
2015-07-10T14:49:17 < dongs> so your serial clockout would need to be orders of magnitude higher
2015-07-10T14:49:42 < zyp> I don't see shift registers
2015-07-10T14:49:45 < zyp> only level shifter
2015-07-10T14:49:49 < Laurenceb> So I told the police my pet goat had just given birth and i needed to comb the babies
2015-07-10T14:50:01 < zyp> no, buffer
2015-07-10T14:50:18 < dongs> err oh, i assumed it was without looking too much cuz fpga had SHIFT/ENC stuff

2015-07-10T15:22:39 < pointertonullval> Can you explain me the why please? :)
2015-07-10T15:22:54 < dongs> you will need to feed 24bit rgb into FPGA, at 2:1 horizontal split you can get away with buffering only 2 scanlines, at 4-way split I think you will need to buffer entire frame
2015-07-10T15:23:03 < dongs> pointertonullval: because pixelclocks, because panel timings, etc
2015-07-10T15:23:38 < dongs> 800x480 panel has liek 26mhz pixclk, what is it going to do wiht pixels that are coming in at 135mhz from hdmi rx?
2015-07-10T15:24:32 < dongs> you will also need to re-generate or create from scratch sync + data enable signals
2015-07-10T15:26:10 < dongs> looks like that panel has no hsync/vsync.
2015-07-10T15:26:11 < dongs> just de + clk
2015-07-10T15:26:18 < dongs> so still
2015-07-10T15:26:30 < dongs> you make DE, and clock out pixels until its full but
2015-07-10T15:26:37 < dongs> panel expects that clock to be at 33mhz
2015-07-10T15:26:49 < dongs> your 1600x original is coming in at 100mhz
2015-07-10T15:28:42 < dongs> infact i think you have to buffer entire frame anyway.
2015-07-10T15:29:11 < dongs> then you can clockout simultaneously to all 4 panels
2015-07-10T15:29:54 < dongs> grab a frame, setup 4 pointers, run your DCLK at 33mhz or whatever for output, and while youre doing that, buffer next incoming frame in antoher buffer, then swap buffers.
2015-07-10T15:29:55 < ReadError> rockout with the clockout
2015-07-10T15:34:16 < dongs> pointertonullval: anyway, it wontwork.
2015-07-10T15:38:43 < pointertonullval> Thanks dongs, I'll forward your consideration to my friend hardware designer, if you have any other consideration would be grate! :)

2015-07-10T15:56:36 < pointertonullval> dongs, so if I'll use displays with lvds interface would be simplest to split?
2015-07-10T15:58:30 < dongs> nope,  you still have the problem of actually splitting it.
2015-07-10T15:58:53 < dongs> output interface is the least of your worries

2015-07-10T23:06:57 < Steffanx> oops
2015-07-10T23:20:49 < KreAture_> Steffanx The dma config where a peripheral is set by the selection of the dma channel and the peripheral device base address is what caued the issue.  They did this simply for saving a register vs using a enum or such for selecting peripheral. My kockup was using the base address wrong so it dereffed.  Forgot the & :)

2015-07-11T01:25:51 < kakimir_> let me sip from your fountain of innovations
2015-07-11T01:27:53 < kakimir_> hmm I need to create kind of right athmosperic working room
2015-07-11T01:28:33 < kakimir_> not just crap piled on top of dust
2015-07-11T01:29:17 < kakimir_> not just an office but studioish kind of...
2015-07-11T01:37:58 < Steffanx> vacuum cleaner?
2015-07-11T01:38:50 < KreAture_> Steffanx neato robotics makes the coolest robotic vacs
2015-07-11T01:38:56 < KreAture_> They use lidar
2015-07-11T01:39:14 < KreAture_> But the old xv-21 series has some issues making the screen die
2015-07-11T01:39:31 < KreAture_> since the machine itself is almost not used, it deserves a fix
2015-07-11T01:40:00 < KreAture_> since the fix isn't enough for my geekdom I am adding some extra fun
2015-07-11T01:40:01 < KreAture_> hehe
2015-07-11T01:40:02 < Tectu> kakimir_, something like this?   https://i.imgur.com/tduvIOF.jpg
2015-07-11T01:40:11 < Tectu> kakimir_, quite old picture, got way more fancier equipment now
2015-07-11T01:42:18 < kakimir_> my friend wanted to protect his shoes when he came in
2015-07-11T01:42:40 < KreAture_> kakimir_ welcome to my world
2015-07-11T01:42:50 < KreAture_> I just finished excavating under the hobbyroom workbench
2015-07-11T01:44:00 < kakimir_> Tectu: sweet
2015-07-11T01:45:04 < kakimir_> is that reflow gun ok?
2015-07-11T01:45:40 < Tectu> for how often I use it yes
2015-07-11T01:45:50 < Tectu> I have access to real reflow equipment so I barely use it
2015-07-11T01:45:59 < Tectu> 80% I use it for heatshrink tubing
2015-07-11T01:46:20 < kakimir_> I have 3kw heatun for reflow. hoe does that compare?

2015-07-11T01:46:51 < Tectu> obviously not at all.
2015-07-11T01:47:20 < kakimir_> so 3kw heatun is the winner
2015-07-11T01:48:01 < Tectu> I didnt know that you had the need to make this become a competition
2015-07-11T01:48:11 < Tectu> but either way: Go have a cookie now
2015-07-11T01:48:37 < kakimir_> but seriously
2015-07-11T01:49:55 < kakimir_> if I want to have less brutal option that heater does just as well?
2015-07-11T01:50:35 < kakimir_> it melts my face and table and hands actually operate that gun
2015-07-11T01:51:07 < Tectu> kakimir_, it works for me. It is obviously a very cheap solution
2015-07-11T01:51:21 < Tectu> kakimir_, I reflow quite a few QFN packages with it. never had issues

2015-07-11T12:58:41 < __rob2> anyone know if I can program and debug an stm32 with an altera usb blaster ?
2015-07-11T12:59:02 < __rob2> with jtag
2015-07-11T12:59:55 < dongs> with openocd, probably
2015-07-11T13:00:04 < dongs> but why would you want to force yourself to such garbagei  dunno
2015-07-11T13:00:14 < dongs> when stlinkv2 is ~free on any disco board
2015-07-11T13:00:32 < __rob2> well so I can program the fpga aswell, with a single header
2015-07-11T13:00:52 < dongs> o i c
2015-07-11T13:00:56 < dongs> i got a better idea 4 u
2015-07-11T13:01:00 < dongs> program fpga with stm32
2015-07-11T13:01:24 < __rob2> yea, that was the other option
2015-07-11T13:01:32 < dongs> it works
2015-07-11T13:01:42 < __rob2> but, I want to be able to use bits like signal tap
2015-07-11T13:01:59 < __rob2> which will require a connection to the fpga through the jtag interface I think
2015-07-11T13:02:01 < dongs> anyway, i duno if STM supporst proper chained jtag
2015-07-11T13:02:03 < dongs> it probably does
2015-07-11T13:02:07 < dongs> as long as you dont mind wasting pins
2015-07-11T13:02:19 < dongs> so youc an stick stm tdo -> tdi on altera
2015-07-11T13:02:33 < dongs> you'llprobly need to config the skip bits stuff in the chain if y ou want to talk directl to altera

2015-07-11T23:54:24 < kakimir_> Tectu: can you toggle another 64MB manually somehow?
2015-07-11T23:55:24 < Tectu> kakimir_, I dont know, but this hangs on the FMC interface so I am pretty sure no
2015-07-11T23:55:54 < Tectu> I dont think that they would connect the highest addresspin to a GPIO because they had no addrespin on the MCU left..
2015-07-11T23:56:06 < Tectu> but before karlp gets ragemode: it is just a fucking personal assumption.
2015-07-11T23:58:16 < kakimir_> how do you use manually toggled ram with memmory controller?

2015-07-12T05:47:55 < dongs> i had a good  run wiht quality japanese ones (JAE) for a while, teh nstock ran outand they only had TE
2015-07-12T05:48:11 < dongs> which were worst, then i got these new i think foxconn or something, they're also almost as nice as jae

2015-07-12T07:59:10 < upgrdman> zyp, would that solder defect be due to a dropped connector before mounting, or something else? (excessive heat?)
2015-07-12T08:01:59 < GargantuaSauce> dongs is there a defect in your pic?
2015-07-12T08:24:22 < ehsanv> Steffanx: yeah, i'm from iran. there was a time that only cracked windows were available.
2015-07-12T08:25:03 < ehsanv> Steffanx: but now licensed products, mostly licensed windows on laptops
2015-07-12T08:26:17 < ehsanv> Steffanx: and bunch of cheap licenses you can buy for anti-virus products and other softwares cheaply, sell in numbers.
2015-07-12T08:26:35 < ehsanv> actually i don't know how it's possible and where they get these!

2015-07-12T08:59:41 < dongs> upgrdman: the connector pins are staggered in height on that TE thing for some insane reason, and it neesd to be pushed down very hard for both heights to make contact
2015-07-12T08:59:48 < dongs> dicknplace didnt push it that much

2015-07-12T13:14:18 < Tectu> so I got that visa for Russia. They decided to write my name in that strange russian font. Looks silly :)
2015-07-12T13:17:31 < __rob2> anyone tell me what the fastest way I can get data from an fpga into an stm32f4 is?
2015-07-12T13:17:59 < jpa-> __rob2: FSMC probably
2015-07-12T13:18:01 < jpa-> with dma
2015-07-12T13:19:04 < __rob2> right, so I'll have to implement the host in the fpga
2015-07-12T13:19:33 < jpa-> that will transfer up to some HCLK/6 16-bit words per second
2015-07-12T13:19:50 < __rob2> was also looking at the camera interface
2015-07-12T13:19:51 < jpa-> host? just a simple parallel bus, with read & write signals
2015-07-12T13:20:32 < jpa-> yeah, may be worth a look, i haven't figured out maximum speed for that; probably limited by dma anyway
2015-07-12T13:20:34 < __rob2> yea, just had a look, that seems an easy way
2015-07-12T13:21:01 < __rob2> really what I want to do is take advantage of the stm32's ethernet
2015-07-12T13:21:12 < __rob2> and pretty much pipe data in and back out
2015-07-12T13:21:35 < __rob2> the rest of the stm32's job is all low freq stuff
2015-07-12T13:22:20 < Tectu> zyp, ping
2015-07-12T13:22:21 < __rob2> all very expensive when you start getting arm hps on the fpga, or get an ethernet core for the fpga
2015-07-12T13:23:55 < Tectu> __rob2, what are you trying to do? I did some project(s) with STM32F4 + FPGA before and now I work with an ARM Cortex-A + FPGA in the same package
2015-07-12T13:24:18 < jpa-> __rob2: hmm, was STM32's ethernet max 10mbit or does it do 100mbit?
2015-07-12T13:24:40 < Tectu> jpa-, it does 100mbit
2015-07-12T13:25:26 < jpa-> yeah, FSMC is still plenty fast for that also
2015-07-12T13:25:34 < Tectu> indeed
2015-07-12T13:25:43 < Tectu> and very easy to use
2015-07-12T13:25:48 < Tectu> and easy to implement on the FPGA too

2015-07-12T13:29:08 < __rob2> jpa- : you mean I should be able to saturate the 100mbit ?
2015-07-12T13:29:22 < jpa-> as far as the FSMC goes, yes
2015-07-12T13:29:48 < jpa-> will of course depend on what else is running on cpu and also on the speed of the network software you are going to use
2015-07-12T13:30:00 < __rob2> i've used lwip before
2015-07-12T13:30:07 < __rob2> not for anything performat tho
2015-07-12T13:30:12 < Tectu> __rob2, personally I found that my prevous STM32F4 + FPGA combination was neary the same price as an FPGA + HPS in one package.
2015-07-12T13:30:27 < __rob2> performant*
2015-07-12T13:30:41 < __rob2> really, what was the device you used ?
2015-07-12T13:30:53 < __rob2> been looking at the lower end cyclone V's
2015-07-12T13:30:59 < Tectu> __rob2, the only thing that might ruin you day is that most HPS+FPGA things (that I know) come with Cortex-A processors and those call for external DDR3 RAM
2015-07-12T13:31:02 < __rob2> without any transcievers
2015-07-12T13:31:13 < Tectu> __rob2, jep, I used some cyclone V
2015-07-12T13:32:33 < Tectu> __rob2, but the issue comes with the handling of the chip. While there are some cyclone V in a non-bga package I think the ones with HPS always just come in BGA
2015-07-12T13:32:43 < Tectu> the lowest pin count package is 484 FPGA when I remember correctly
2015-07-12T13:32:58 < Tectu> and the big issue really is the DDR3 when it comes to layouting / PCB design
2015-07-12T13:33:37 < Tectu> __rob2, when this is just a one-off prototype to show something or to learn you might want to just stick one of these on your board: https://www.terasic.com.tw/cgi-bin/page/archive.pl?Language=English&No=941
2015-07-12T13:34:18 < __rob2> yes, I've actually bought one of those yesterday
2015-07-12T13:35:39 < __rob2> but theres alot of custom bits on the same pcb, so would rather just layout the whole thing
2015-07-12T13:36:30 < __rob2> so did you use the ethernet on your hps design ?
2015-07-12T13:37:31 < __rob2> problem with a raw fpga solution is the cost of the ethernet cores. which is what I am trying to avoid
2015-07-12T13:38:07 < Tectu> __rob2, I have a DE1-SoC and I use(d) the ethernet there, yes
2015-07-12T13:38:23 < Tectu> __rob2, but the ethernet is directly connected to the HPS, just throw in some PHY and it works. No FPGA magic invovled
2015-07-12T13:38:39 < __rob2> so you used lwip or something ?
2015-07-12T13:39:10 < Tectu> __rob2, I am sure that you can find some semi decent open sorez / public domain IP core. The question I am not sure about is how easy they are to use without a soft CPU (I don´t know networking so well)
2015-07-12T13:39:28 < Tectu> __rob2, no, I run linux on that HPS, just the built-in networking crap worked for me
2015-07-12T13:39:41 < Tectu> __rob2, Only thing I did was giving it a static IP :D
2015-07-12T13:39:43 < Tectu> the rest just works
2015-07-12T13:39:50 < __rob2> well from my experience in s/w I can see tcp on an fpga being hard :P
2015-07-12T13:40:01 < __rob2> but there is almost no barrier for getting it up and running in software
2015-07-12T13:40:15 < Tectu> __rob2, I thought so. Afaik you would really need a soft CPU for that but other people here might have more experienced/professional ideas to throw in
2015-07-12T13:40:40 < Tectu> __rob2, the cheapest cyclone V features a single core A8 with 800 MHz when I remember correctly
2015-07-12T13:40:49 < Tectu> in an FBGA 484 package
2015-07-12T13:41:01 < Tectu> the thing I fear most is the DDR3. I have not done my custom design yet.
2015-07-12T13:41:35 < Tectu> The DE0-nano-soc came out just a few weeks ago. it didn´t exist whe I started with the cyclone V. I guess I will just go for that board and make a custom motherboard for it. will save a lot of time, pain and money
2015-07-12T13:41:47 < Tectu> but that is just for something I make 5 devices so...
2015-07-12T13:41:53 < Tectu> not a problem :)
2015-07-12T13:43:48 < Tectu> __rob2, depending on what you are doing: There are a few companies that sell modules such as this one:  http://www.enclustra.com/en/products/system-on-chip-modules/mars-ma3/
2015-07-12T13:44:19 < Tectu> __rob2, I got some quotes and at least for me it is way to expensive. The one I just linked comes in at 480$ a single piece. the dev board is at 280$
2015-07-12T13:44:34 < Tectu> and prices dont really go down until you are going for >=100 pcs

2015-07-12T17:08:07 < Tectu> dongs, nede to get those headers-to-4mm adapter cables
2015-07-12T17:08:14 < Tectu> dongs, I don-t know what to do with out them. Use them nearly daily.

2015-07-12T17:12:06 < dongs> jpa hax looks nice
2015-07-12T17:12:12 < dongs> yes, i need to pick up some super sharp multimeter probes.
2015-07-12T17:12:26 < dongs> got sharp scope probes, but they're not usable as quick poking into things/continuity testing stuff.

2015-07-12T17:14:20 < Tectu> they got some rediculously sharp gold tip probes
2015-07-12T17:14:43 < dongs> my fluke takes those standard 'test leads' things that are like angled banana plugs
2015-07-12T17:14:50 < Tectu> dongs, http://www.probemaster.com/product_info.php?cPath=2_12&products_id=198
2015-07-12T17:14:59 < dongs> yeah, that looks good
2015-07-12T17:15:14 < Tectu> dongs, they are pretty decent. and last time I checked not expensive at all
2015-07-12T17:15:15 < dongs> price is win too
2015-07-12T17:15:18 < dongs> bookmarking and ordering
2015-07-12T17:15:26 < Tectu> jeah, they are nice. love them
2015-07-12T17:17:48 < Steffanx> Only $16 :S
2015-07-12T17:23:54 < Steffanx> And skyhigh shippingcosts nice
2015-07-12T17:24:34 < dongs> does qty 1 buy yuou a pair
2015-07-12T17:24:37 < dongs> or one probe
2015-07-12T17:25:30 < Steffanx> I would guess a pair because i see no colour option
2015-07-12T17:25:34 < dongs> right
2015-07-12T17:25:56 < Tectu> dongs, experience says one pair
2015-07-12T17:28:15 < dongs> ordered and shipped to use for $6.25
2015-07-12T17:28:22 < dongs> Steffanx: shipping was only ridiculous for sending to jp
2015-07-12T17:28:24 < PeterM> dongs does wifecop have sewing needles, i find the thick ones pretty good as improv probes

2015-07-12T17:29:18 < dongs> and i'd still need to get them clipped to the multimeter probes
2015-07-12T17:29:23 < Tectu> are there dongsoffsprings too?
2015-07-12T17:29:25 < dongs> might as well get this done rihgt
2015-07-12T17:29:28 < Steffanx> Yes skyhigh dongs ;)
2015-07-12T17:29:48 < PeterM> dongs also, ive bought from probemaster before, maybe 10 sets pof probes, shipping was cheap but had to email them for correct shipping cost
2015-07-12T17:29:55 < Tectu> dongs, I am sure you have one other tiny thing suitable to be used as an SMD probe...
2015-07-12T17:30:41 < dongs> PeterM: o rite, i saw something about mmailing a dude for USPS rates
2015-07-12T17:30:52 < dongs> o well, i have a box coming from alaska to here next week anywayt
2015-07-12T17:30:55 < PeterM> 9 sets of probes was $50 shipping to middleofnewhere australia
2015-07-12T17:31:18 < dongs> sounds like usps

2015-07-12T20:32:37 < Steffanx> that's a weird kind of incest and inbred
2015-07-12T20:34:37 < decimad> hrmm, should one enforce correct integer arithmetic usage... as in, don't allow a sum if it is not guaranteed both numbers have a spare bit f.e.?
2015-07-12T20:35:48 < decimad> that one is stronger than the actual precondition... otoh it's hard to check the precondition given you can't access the overflow bit
2015-07-12T20:36:28 < decimad> I wonder if the stronger checks render it unusable...
2015-07-12T20:36:48 < decimad> Wasting precision everywhere then...
2015-07-12T20:42:50 < aandrew> https://www.youtube.com/watch?v=4R0oXjIzOx4
2015-07-12T20:43:19 < rkreis_> decimad, interesting, ideally, you could prove at or before compile time that no overflows occur
2015-07-12T20:44:04 < rkreis_> if you go through the effort of detecting things like that at random, what would you do if an overflow does actually occur? abort()?
2015-07-12T20:44:19 < rkreis_> *at runtime
2015-07-12T20:46:04 < decimad> rkreis_ yes, well, it's just hard to generally prove the correct way... so just using the bits involved is easier ... but wastes bits
2015-07-12T20:48:48 < decimad> so if you happen to gurantee that some numbers are a : 15.4 and b : 13.4 (integer.fractional), then obviously a + b always fits into 16.4 ... but other cases with stronger preconditions would fit too
2015-07-12T20:56:26 < Taxman> re
2015-07-12T21:11:27 < rkreis_> decimad, are you overdoing it?
2015-07-12T21:11:52 < Tectu> gotta need that precision to flash some LEDs mate!
2015-07-12T21:12:12 < decimad> rkreis_ no, I was just thinking... i leave this to the programmer ;)
2015-07-12T21:12:31 < rkreis_> are you implying that you're writing a fixed point math lib?
2015-07-12T21:14:01 < decimad> I don't know if you can say someone is implying if he didnt actively try to do so
2015-07-12T21:14:31 < decimad> implying or not, i'm doing it
2015-07-12T21:15:12 < Laurenceb> Tectu: I thought F7 backlight was i2c controlled?
2015-07-12T21:15:30 < rkreis_> and the main problem is that C doesn't tell you if there was an overflow when doing int maths?
2015-07-12T21:16:23 < Tectu> Laurenceb, no, who says such things?
2015-07-12T21:16:40 < decimad> rkreis_ i don't really have a problem. I just had the thought that my lib could warn about 16.16 + 16.16 but allow 15.16+15.16
2015-07-12T21:17:06 < decimad> rkreis_ it could also silently calculate 17.15
2015-07-12T21:17:24 < rkreis_> i'd consider giving each number an allowed value range (and maybe enforce it or maybe not), that's more precise than just working in bits
2015-07-12T21:17:25 < decimad> but either way will only be strange
2015-07-12T21:17:27 < Tectu> Laurenceb, they have the enable pin of some regulator chip hoooked up to GPIO like any sane person. but they picked a GPIO with absoutely no AF beside normal GPIO and LTDC...
2015-07-12T21:19:33 < rkreis_> well, those are mostly design issues - i can make guesses what advantages/disadvantages certain decisions will lead to, and if one decision makes sense together with another one, but i suspect you can do that just as well :)
2015-07-12T21:19:44 < Tectu> decimad, what lib?
2015-07-12T21:20:39 < decimad> rkreis_ i'd like that too... but it's hard to keep hold of reals in templates.. which sucks... don't want to start with rationals... so I'll just keep this task to the programmer... the lib helps enough already ;)
2015-07-12T21:20:40 < Laurenceb> surely you dont want to PWM the EN pin
2015-07-12T21:21:35 < Laurenceb> oh thats LCD I2C
2015-07-12T21:21:54 < rkreis_> decimad, if std:: can use rationals, so can you - especially with those shiny new user defined literals
2015-07-12T21:22:20 < Tectu> Laurenceb, the EN pin of the regulator for the backlight
2015-07-12T21:22:27 < Tectu> Laurenceb, LCD I2C is the touchscreen controller magic
2015-07-12T21:22:30 < Laurenceb> yeah
2015-07-12T21:22:40 < Laurenceb> annoying
2015-07-12T21:22:47 < decimad> rkreis_ it's not something about what I can do or not, I just don't want to clutter the source with rational reps of real numbers.
2015-07-12T21:23:16 < rkreis_> alright
2015-07-12T21:23:40 < rkreis_> if there's any halfway ready code or project page, i'd love to hear about it
2015-07-12T21:26:15 < Tectu> <Tectu> decimad, what lib?
2015-07-12T21:26:38 < decimad> Tectu the small lib i'm currently writing
2015-07-12T21:27:06 < Tectu> decimad, yes... library for what? about what?
2015-07-12T21:27:33 < decimad> Tectu well... fixed point? :)
2015-07-12T21:27:51 < Tectu> ok :)
2015-07-12T21:28:28 < decimad> I guess rkreis_ expects trigonometric functions and whatnot ;)
2015-07-12T21:29:04 < rkreis_> well, not all of them :)

2015-07-12T22:15:31 < krakapwa> Laurenceb: howdy
2015-07-12T22:15:42 < krakapwa> i'm still strugglign with fatfs
2015-07-12T22:15:45 < Laurenceb> ok
2015-07-12T22:15:54 < Laurenceb> did you read my code?
2015-07-12T22:15:57 < krakapwa> did u have to fiddle around with dma interrupts?
2015-07-12T22:16:06 < krakapwa> yeah it helped quite a bit
2015-07-12T22:16:12 < krakapwa> thanks btw
2015-07-12T22:16:32 < krakapwa> while ((DMAEndOfTransfer == 0x00) && (TransferEnd == 0) && (TransferError == SD_OK) && (timeout > 0))
2015-07-12T22:16:35 < krakapwa>   {
2015-07-12T22:16:38 < krakapwa>     timeout--;
2015-07-12T22:16:39 < krakapwa> my code is hanging here
2015-07-12T22:16:41 < krakapwa>   }
2015-07-12T22:16:52 < krakapwa> one of DMAendoftransfer and tranferend is changed
2015-07-12T22:17:07 < krakapwa> and my code is redirected in some kind of hidden function
2015-07-12T22:17:54 < krakapwa> i'm basically experiencing the same issue as this guy: http://www.iwasz.pl/electronics/stm32f407-sdio-tests/
2015-07-12T22:18:02 < Laurenceb> did you enable the DMA?
2015-07-12T22:18:17 < Laurenceb> I managed to reuse code for USB too
2015-07-12T22:18:51 < krakapwa> i believe so
2015-07-12T22:18:52 < Laurenceb> https://github.com/Laurenceb/STM32-Logger/blob/master/Util/fat_fs/src/sd_spi_stm32.c
2015-07-12T22:19:26 < Laurenceb> iirc all my code is in there
2015-07-12T22:20:26 < Laurenceb> https://github.com/Laurenceb/STM32-Logger/blob/master/gpio.c
2015-07-12T22:20:27 < krakapwa> im actually using sdio
2015-07-12T22:20:35 < Laurenceb> line 36+, the config is important
2015-07-12T22:20:36 < Laurenceb> oh
2015-07-12T22:20:45 < Laurenceb> I've never used SDIO, so i dont know
2015-07-12T22:21:30 < krakapwa> damn
2015-07-12T22:21:50 < Laurenceb> heh
2015-07-12T22:22:08 < Laurenceb> DMAEndOfTransfer == 0x00
2015-07-12T22:22:21 < Laurenceb> wait you use interrupt to detect end of transfer/
2015-07-12T22:22:27 < krakapwa> anyways i notice that my code hangs in some infinite loop that i cannot find
2015-07-12T22:22:40 < krakapwa> yes
2015-07-12T22:23:05 < Tectu> WWDG_IRQHandler wtf
2015-07-12T22:23:05 < krakapwa>  #define SD_SDIO_DMA_IRQHANDLER        DMA2_Stream3_IRQHandle
2015-07-12T22:23:14 < krakapwa> i am implementing that function
2015-07-12T22:23:53 < Steffanx> Tectu that is just the name of the unhandled exception handler
2015-07-12T22:23:57 < Laurenceb> try putting a breakpoint in your interrupt
2015-07-12T22:24:03 < Laurenceb> what Steffanx said
2015-07-12T22:24:08 < Laurenceb> info registers
2015-07-12T22:24:18 < Laurenceb> ^ Tectu
2015-07-12T22:24:25 < krakapwa> there are breakpoints but the handler is never called
2015-07-12T22:24:43 < krakapwa> u think it calls WWDG_IRQHandler ?
2015-07-12T22:25:08 < Steffanx> no its probably some other irq you do not handle
2015-07-12T22:25:12 < Steffanx> like hardfault or something
2015-07-12T22:25:13 < Tectu> yeah. i am trying to track down some HardFault that was caused by INVSTAT and there it tells me to look at the PC because it will point me at the line that fucked things up. Now I did some stuff in the hardfault handler as recommended by google to save those registers so I can read them with the debugger. now I get WWDG_IRQHandler crap
2015-07-12T22:25:16 < Tectu> Laurenceb ^
2015-07-12T22:25:48 < Laurenceb> what
2015-07-12T22:25:50 < Laurenceb> backtrace?
2015-07-12T22:25:55 < Tectu> does not fork
2015-07-12T22:26:04 < Tectu> getting corrupt stack, cant get back
2015-07-12T22:26:07 < Laurenceb> what does "backtrace" say
2015-07-12T22:26:08 < Laurenceb> oh
2015-07-12T22:26:16 < Laurenceb> hmm maybe your debug session broke
2015-07-12T22:26:22 < Steffanx> you can also grep the gdb script somewhere in Laurenceb's git repo Tectu
2015-07-12T22:26:22 < Laurenceb> you might need to try again :-/
2015-07-12T22:26:29 < Steffanx> that will help you debugging hardfaults
2015-07-12T22:26:31 < Steffanx> or other faults
2015-07-12T22:26:33 < Laurenceb> indeed
2015-07-12T22:26:46 < Laurenceb> but sometimes your session might be too bjorked :-/
2015-07-12T22:26:46 < Tectu> Steffanx, u telling me that Laurenceb can be helpful?
2015-07-12T22:26:50 < Steffanx> https://github.com/Laurenceb/STM32-Logger/blob/master/jtag/armv7m-macros.gdb
2015-07-12T22:26:58 < Steffanx> nah its not his, but i know it's somewhere there
2015-07-12T22:27:16 < Tectu> ah jpa- showed it once. I thought he said that Laurenceb ripped-it-off somewhere else :p
2015-07-12T22:27:26 < Steffanx> it might also be in the zyp snips but im not sure
2015-07-12T22:27:45 < Tectu> anyway, why would I get WWDG_IRQ
2015-07-12T22:28:01 < Laurenceb> bacause its the first name defined at that address
2015-07-12T22:28:08 < Laurenceb> that address being the default handler
2015-07-12T22:28:20 < Steffanx> not the last name Laurenceb?
2015-07-12T22:28:31 < Tectu> no, WWDG_IRQ is the first IRQ in STM32
2015-07-12T22:28:34 < Tectu> (after the cortex ones)
2015-07-12T22:28:48 < Steffanx> i thought it was some alphabetically thing, but that could be right too
2015-07-12T22:29:43 < Tectu> Laurenceb, I understand. ST people use default handler for some other handler and that is just an infinite loop. hence WWD starts bitching I guess?
2015-07-12T22:30:23 < Tectu> Steffanx, http://paste.ugfx.org/show/b6006dd61e
2015-07-12T22:30:40 < Tectu> Steffanx, line 1 to 14 are cortex IRQs
2015-07-12T22:31:48 < Steffanx> yes yes, it's a better explanation why gdb says wwdg_irq
2015-07-12T22:32:39 < Tectu> Laurenceb, I try to do this:  http://www.freertos.org/Debugging-Hard-Faults-On-Cortex-M-Microcontrollers.html
2015-07-12T22:33:06 < Tectu> Laurenceb, right now I end up in HardFault_Handler which is just an infinite loop. hence PC gets fucked up (probably)
2015-07-12T22:33:07 < Steffanx> y u no try script? Easy much
2015-07-12T22:33:12 < krakapwa> Tectu: How do u know i'm getting a harfault?
2015-07-12T22:33:54 < Tectu> Steffanx, which scripty
2015-07-12T22:34:15 < Tectu> krakapwa, not you, me ^^
2015-07-12T22:35:05 < Tectu> Steffanx, got it
2015-07-12T22:35:11 < krakapwa> ok. can u point me to a solution?
2015-07-12T22:35:26 < krakapwa> my code idles somewhere and im trying to know where
2015-07-12T22:35:50 < krakapwa> i guess some interrupt is called but dunno which one
2015-07-12T22:36:04 < Tectu> Laurenceb, anyway,  when I get a hardfault and ARM RM tells me to look at PC because it holds the value to the instruction that caused the hardfault, then I put a breakpoint BEFORE the loop in the hardfault handler but the PC value seems fucked up
2015-07-12T22:36:18 < Laurenceb> Tectu: set a breakpoint at the "WWDG"
2015-07-12T22:36:31 < Laurenceb> hmm
2015-07-12T22:37:06 < Laurenceb> cant you add a hardfault handler?
2015-07-12T22:37:15 < Tectu> Laurenceb, I dont get any WWDG anymore, I removed the freeRTOS code. now back to my hardfault handler
2015-07-12T22:37:20 < Tectu> Laurenceb, I have one.
2015-07-12T22:37:23 < Laurenceb> ok cool
2015-07-12T22:37:25 < Tectu> Laurenceb, it is just an empty while(1);
2015-07-12T22:37:39 < Tectu> Laurenceb, then I look at registers and PC is  0x800E2F0
2015-07-12T22:37:43 < Laurenceb> so "break <name of handler function>"
2015-07-12T22:37:45 < Laurenceb> ok
2015-07-12T22:37:48 < Tectu> Laurenceb, did that
2015-07-12T22:37:55 < Laurenceb> when it break, "backtrace"
2015-07-12T22:37:59 < Laurenceb> *breaks
2015-07-12T22:38:19 < Tectu> Laurenceb, http://paste.ugfx.org/show/14fd4b1a03
2015-07-12T22:38:28 < Tectu> Laurenceb, as I said, not helpful.
2015-07-12T22:38:36 < Laurenceb> hmm
2015-07-12T22:38:41 < Laurenceb> it might just be correct :P
2015-07-12T22:38:48 < Tectu> Laurenceb, but when ARM manual tells me to look at PC value which I do using info reg, and PC = 0x800E2F0, shouldnt I find that in the objdump -d file?
2015-07-12T22:38:57 < Laurenceb> could you have called null ?
2015-07-12T22:39:09 < Tectu> Laurenceb, likely, but I dont know where.
2015-07-12T22:39:12 < Laurenceb> hmm
2015-07-12T22:39:21 < Laurenceb> sure you built with debugging?
2015-07-12T22:39:47 < Tectu> Laurenceb, yes,   -ggdb -O0 -std=c99 -g3
2015-07-12T22:39:50 < Laurenceb> i guess it knows where HardFault hander is, but your makefile might still be screwy
2015-07-12T22:39:54 < Laurenceb> ok
2015-07-12T22:40:04 < Laurenceb>  -O0 is glitchy in my experience
2015-07-12T22:40:10 < Laurenceb> I never use it
2015-07-12T22:40:20 < Tectu> Laurenceb, some background information: the same code runs on an M4 w/o any issues.
2015-07-12T22:40:27 < Laurenceb> right
2015-07-12T22:40:29 < Tectu> Laurenceb, remember that this is M7 magicxxx
2015-07-12T22:40:33 < Laurenceb> yes
2015-07-12T22:40:37 < decimad> Would you like your lib to bark "error C2338: No bits left, dude!" ?
2015-07-12T22:41:06 < Laurenceb> this is maybe a bit odd :-/
2015-07-12T22:41:06 < Tectu> Laurenceb, any fancy ideas?
2015-07-12T22:41:21 < Tectu> decimad, depends. does it support in-app purchases? ;)
2015-07-12T22:41:21 < Laurenceb> well I've had issues with hardfaults on M4
2015-07-12T22:41:33 < Laurenceb> but never seen something quite like that
2015-07-12T22:41:33 < Tectu> Laurenceb, who hasn`t ;P
2015-07-12T22:41:36 < Tectu> Laurenceb, same here
2015-07-12T22:41:42 < Tectu> Laurenceb, what do I do?
2015-07-12T22:41:50 < Laurenceb> why 0x000000000x00000000
2015-07-12T22:41:52 < Laurenceb> 64 bits?
2015-07-12T22:42:03 < Tectu> Laurenceb, yes, M7 has 64 bit instruction bus width
2015-07-12T22:42:09 < Tectu> Laurenceb, one of the main new features over M4
2015-07-12T22:42:58 < Laurenceb> hmm
2015-07-12T22:43:04 < Tectu> Laurenceb, note that ´Normal´code works well. this crap happens as soon as I enable the setjmp/longjmp scheduller magic (which works fine on F1, F2 and F4 (so most likely F3 too as that is M4))
2015-07-12T22:43:05 < Laurenceb> cant you just dump the stack?
2015-07-12T22:43:16 < Laurenceb> and link register... i forget how it all works lol
2015-07-12T22:43:18 < Tectu> Laurenceb, how?  (sorry, I am not that experienced with debugging)
2015-07-12T22:43:26 < Tectu> Laurenceb, sure, I have all the info reg here
2015-07-12T22:43:36 < Laurenceb> simple then
2015-07-12T22:44:25 < Tectu> Laurenceb, http://screencast.com/t/uWGYJkAhpBCv
2015-07-12T22:44:30 < Laurenceb> oh god
2015-07-12T22:44:39 < decimad> well, maybe m7 introduced new rules for operation target addresses, just like the 0x1 in m4?
2015-07-12T22:45:03 < Laurenceb> 0x2004ff70 is stack
2015-07-12T22:45:06 < Tectu> decimad, I am sadly not that much of a core guy (although I wish I would be) so no idea
2015-07-12T22:45:07 < Tectu> Laurenceb, yep
2015-07-12T22:45:33 < Laurenceb> is this gdb?
2015-07-12T22:45:41 < Tectu> Laurenceb, this is GDB with OpenOCD
2015-07-12T22:45:50 < Taxman> Tectu: I had those WWDG_handlcer crashed, too, you remember? But with ugfx and F4
2015-07-12T22:45:54 < Tectu> Laurenceb, just a facny plugin, but I verified, I get same results when doing it DIY in GDB terminal
2015-07-12T22:46:11 < Tectu> Taxman, yes, blame uGFX ;P
2015-07-12T22:46:32 < Taxman> i do not know who to blame at the moment
2015-07-12T22:46:57 < Tectu> Laurenceb,
2015-07-12T22:46:57 < Tectu> FLASH (rx)      : ORIGIN = 0x08000000, LENGTH = 1024K
2015-07-12T22:46:58 < Tectu> RAM (xrw)      : ORIGIN = 0x20000000, LENGTH = 320K
2015-07-12T22:47:14 < Ecco> 320K? Tectu: what device?
2015-07-12T22:47:23 < Tectu> Ecco, STM32F746NGH
2015-07-12T22:47:28 < Ecco> Oh it's out already?
2015-07-12T22:47:43 < Tectu> Ecco, jup, since quite a few weeks nwo
2015-07-12T22:47:44 < Tectu> now*
2015-07-12T22:47:49 < Ecco> Where can I buy one?
2015-07-12T22:47:54 < Tectu> Ecco, but dont get too excited, nobody supports it yet
2015-07-12T22:47:58 < Ecco> Google yields only one (non-relevant) now
2015-07-12T22:48:09 < Tectu> Ecco, had to do some manual patching of OpenOCD and even some real by had edits to get OpenOCD working
2015-07-12T22:48:16 < Ecco> Oh, really?
2015-07-12T22:48:27 < Ecco> Weird though, I thought it'd use STLink like the previous ones
2015-07-12T22:48:38 < Tectu> Ecco, I wish people would not ask me to get my crap running on that board ASAP. I didnt do much beside trying getting this M7 crap up and running this week
2015-07-12T22:48:48 < Laurenceb> http://www.delorie.com/gnu/docs/gdb/gdb_56.html
2015-07-12T22:48:49 < Tectu> Ecco, it does, but M7 is different than M4
2015-07-12T22:48:50  * aandrew sighs
2015-07-12T22:49:02 < Tectu> Laurenceb, what am I going to examine?
2015-07-12T22:49:13 < aandrew> I should get off my ass and try to get this stm32f4 demo board running lwip/ppp
2015-07-12T22:49:40 < Tectu> aandrew, in case of: ChibiOS/RT has some LwIP demos that work out of the box on a few F4 boards
2015-07-12T22:49:52 < Ecco> Tectu: I guess you're using the F7 disco board?
2015-07-12T22:49:59 < aandrew> interesting, thanks Tectu
2015-07-12T22:50:05 < Tectu> Ecco, yes, my F7 eval board is still on its way
2015-07-12T22:50:14 < Tectu> aandrew, no problem :)
2015-07-12T22:50:18 < Laurenceb>  p *0x2004ff70
2015-07-12T22:50:24 < Laurenceb> etc
2015-07-12T22:50:32 < Tectu> Laurenceb,   1    ....
2015-07-12T22:50:34 < Ecco> Tectu: So how can you try openocd then?
2015-07-12T22:50:47 < Tectu> <Tectu> Ecco, had to do some manual patching of OpenOCD and even some real by had edits to get OpenOCD working
2015-07-12T22:51:00 < Ecco> I don't understand :)
2015-07-12T22:51:08 < Laurenceb> then reduce the address
2015-07-12T22:51:21 < Ecco> You said "my F7 board is on its way" which implies you don't have it now
2015-07-12T22:51:28 < Tectu> Laurenceb, beginners question: stack on cortex M goes up or down?
2015-07-12T22:51:31 < Ecco> so what are you using openocd with?
2015-07-12T22:51:37 < Ecco> down
2015-07-12T22:51:43 < Laurenceb> down
2015-07-12T22:51:51 < Tectu> Ecco, you asked whether I am using the F7 disco and I replied with yes.
2015-07-12T22:52:00 < Laurenceb> Tectu: looks like you called 0xFFF etc
2015-07-12T22:52:02 < Ecco> ok, but then you said "it's on its way"
2015-07-12T22:52:05 < Tectu> Ecco, it is here on my table waiting for Laurenceb to finally be useful ;P
2015-07-12T22:52:08 < Laurenceb> thats why you cant backtrace
2015-07-12T22:52:10 < Ecco> ooooooooh
2015-07-12T22:52:11 < Ecco> ok
2015-07-12T22:52:14 < Laurenceb> no code at 0xFF

2015-07-12T22:52:22 < Ecco> So have you tried the capacitive screen? Is it any good?
2015-07-12T22:52:26 < Laurenceb> stack might help
2015-07-12T22:52:27 < Ecco> (I guess it came with a demo app)
2015-07-12T22:52:53 < Tectu> Ecco, the display module on that F7 discovery is very good. I also have an F439i-EVAL board and they already use the capacitive touchscreen there too. it is pretty awesome
2015-07-12T22:52:55 < Ecco> Wow, it's 45€ :-)
2015-07-12T22:52:56 < Ecco> Nice
2015-07-12T22:53:01 < Tectu> Laurenceb, stack might help?
2015-07-12T22:53:10 < Laurenceb> you should see some addresses in the stack
2015-07-12T22:53:14 < Tectu> Ecco, the board is very nice. really.
2015-07-12T22:53:19 < Steffanx> tried it yet Tectu?
2015-07-12T22:53:20 < Laurenceb> where you were in nested functions before it all went to shit
2015-07-12T22:53:21 < Ecco> Yeah it seems like it is
2015-07-12T22:53:28 < Tectu> Laurenceb, uhm, examining the stack?
2015-07-12T22:53:30 < Laurenceb> yes
2015-07-12T22:53:58 < Tectu> Laurenceb, some stuff like  x/128b 0x2004ff70  ?
2015-07-12T22:54:01 < Laurenceb> hmm maybe backtrace uses the stack?
2015-07-12T22:54:04 < Tectu> Steffanx, jup
2015-07-12T22:54:05 < Laurenceb> im not 100% sure
2015-07-12T22:54:09 < Ecco> Hmm, the chips are awfully expensive though
2015-07-12T22:54:21 < Ecco> (Farnell starts them at 12€ for 50+)
2015-07-12T22:54:22 < Tectu> Ecco, money is no issue. just go to the bank and get some :)))
2015-07-12T22:54:31 < Laurenceb> Tectu or p x *0x2004ff70
2015-07-12T22:54:51 < Ecco> Tectu: The only issue is convincing your customers that money is indeed not an issue
2015-07-12T22:54:52 < Tectu> Laurenceb, that is 0x1 again ;P
2015-07-12T22:55:06 < Laurenceb> go backwards in units of 4 bytes
2015-07-12T22:55:13 < Tectu> Ecco, never had to do that. the companies I work for usually have too much of it anyway.
2015-07-12T22:55:17 < Tectu> Ecco, but I am not a sales man.
2015-07-12T22:55:19 < Ecco> :-)
2015-07-12T22:55:37 < Ecco> It's weird that your code that ran fine on M4 hard faults on M7 though
2015-07-12T22:55:41 < Laurenceb> really you need a script for this
2015-07-12T22:55:44 < Tectu> Ecco, if you can go get an F7 discovery. it really is a nice board. The display is awesome and the rest of the peripherals too.
2015-07-12T22:55:45 < Ecco> I thought it was suppoed to be backward-compatible
2015-07-12T22:55:49 -!- barthess [~barthess@37.44.65.179] has joined ##stm32
2015-07-12T22:55:56 < Ecco> Tectu: I most definitely will
2015-07-12T22:55:56 < Laurenceb> itd help if i knew how "backtrace" works
2015-07-12T22:55:58 < Tectu> Ecco, yes, indeed
2015-07-12T22:55:58 < Laurenceb> in gdb
2015-07-12T22:56:06 < Tectu> Laurenceb, the scrip from your repo will do or some other custom magic?
2015-07-12T22:56:07 < Ecco> but the project I'm working on right now will require a very cheap MCU
2015-07-12T22:56:19 < Laurenceb> i meant a script to dump the stack
2015-07-12T22:56:21 < Ecco> so the STM32F7 I'll undoubtely purchase will be just for fun
2015-07-12T22:56:28 < Tectu> Ecco, they only screwed to things up as far as I can tell:  they put a 128MBit SDRAM there but only 64MBit are addressable
2015-07-12T22:56:36 < Ecco> whaaaaat?
2015-07-12T22:56:38 < Laurenceb> i think there is a macro to do this
2015-07-12T22:56:51 < Tectu> Ecco, and it says 128 MBit on all the specs sheets and even the packaging :D
2015-07-12T22:57:02 < Tectu> Ecco, just when you start using it you realize that some notes tell that...
2015-07-12T22:57:03 < Steffanx> it also says on the package only 64mbit is available
2015-07-12T22:57:06 < Ecco> They forgot to wire the most significant bit on the bus or what?
2015-07-12T22:57:08 < Tectu> Steffanx, not on mine
2015-07-12T22:57:18 < Tectu> Ecco, well, forgot or pin confligt. I have not checked.
2015-07-12T22:57:21 < Steffanx> im sure it did on the photo i saw
2015-07-12T22:57:29 < Ecco> Well, anyway, in general that RAM is just used for the framebuffer
2015-07-12T22:57:42 < Ecco> and 64M is more than enough anyway
2015-07-12T22:57:47 < Ecco> but yeah, that blows :)
2015-07-12T22:57:51 < Tectu> Ecco, the other thing they screwed up is that the hooked up the pin that controlls the LCD brightness to a GPIO that is not internally connected to a timer, so just GPIO bitbanging -> no PWM for you
2015-07-12T22:58:16 -!- barthess [~barthess@37.44.65.179] has quit [Client Quit]
2015-07-12T22:58:17 < Tectu> Ecco, I agree, still more than enought. but not sure why they populate it with 128 Mbit. I am sure they can get 64MBit chips from the same supplier.
2015-07-12T22:58:25 < Ecco> oh, and the brightness expect to be pwm'ed?
2015-07-12T22:58:39 < Ecco> Or you mean there's no controlelr, you just PWM so that, on average, it's more or less bright?
2015-07-12T22:58:44 < Tectu> Ecco, yes, it would.
2015-07-12T22:58:51 < Ecco> ok
2015-07-12T22:59:01 < Ecco> Seems like a solid proto board though
2015-07-12T22:59:02 < Tectu> Ecco, the hardware to do it is there, just the pin that it is hooked up is not suitable for that
2015-07-12T22:59:07 < Ecco> I have the F4 disco, I love it :)
2015-07-12T22:59:12 < Tectu> Ecco, the quality of the board is very good.
2015-07-12T22:59:19 < Ecco> I guess
2015-07-12T22:59:26 < Tectu> Ecco, do you also have an F429i-Discovery? that board was/is a complete disgrace
2015-07-12T22:59:31 < Tectu> Ecco, worst board  ever made ;P
2015-07-12T22:59:31 < Laurenceb> hmm im not sure how to do this :-/
2015-07-12T22:59:35 < Ecco> Really?
2015-07-12T22:59:39 < Ecco> I really like it
2015-07-12T22:59:40 < Tectu> Laurenceb, help :(
2015-07-12T22:59:45 < Ecco> what do you think is so bad?
2015-07-12T22:59:49 < Tectu> Ecco, yes, I got about two dozen of them and gave them back ;P
2015-07-12T22:59:56 < Ecco> Why? Defective?
2015-07-12T23:00:01 < Tectu> no, they work.
2015-07-12T23:00:10 < Tectu> but the pin conflicts on that thing, barely usable for anything
2015-07-12T23:00:14 < Ecco> Oh
2015-07-12T23:00:18 < Tectu> Ecco, and the worst is the display quality. ask Steffanx
2015-07-12T23:00:19 < Ecco> Yeah this I have to agree on
2015-07-12T23:00:30 < Ecco> Yeah allright, the display is pretty bad
2015-07-12T23:00:35 < Ecco> *but* it's very cheap
2015-07-12T23:00:40 < Laurenceb> https://blog.feabhas.com/2013/02/developing-a-generic-hard-fault-handler-for-arm-cortex-m3cortex-m4/
2015-07-12T23:01:20 < Tectu> Ecco, they made their demo use a very specific set of colors so it looks somewhat useful, but whenever you use any other colors than those 5 ones that look good it looks like a fish that swam through diarrhea and was sitting in the sun for three weeks after it died due to AIDS
2015-07-12T23:01:31 < Tectu> Laurenceb, checking that out...
2015-07-12T23:01:37 < decimad> Laurenceb: I used that one for profit too... but makes me wonder why the debuggers cannot backtrack fault handlers if you can do it manually...
2015-07-12T23:01:52 < Laurenceb> https://blog.feabhas.com/wp-content/uploads/2013/01/intEntryStack_small.jpg
2015-07-12T23:02:05 < Tectu> Ecco, the price/performance of the F7 discovery vs. the F429i Discovery is pretty epic. The f7 does not cost that much more and it is by far better
2015-07-12T23:02:18 < Ecco> Tectu: Sure :)
2015-07-12T23:02:19 < Laurenceb> bbl
2015-07-12T23:02:23 < Tectu> Laurenceb, thanks!
2015-07-12T23:02:34 < Ecco> But if you don't need performances, I still think it's a decent board
2015-07-12T23:02:52 < Tectu> Ecco, when you dont buy it for the display, yes. and that is what it is meant for.
2015-07-12T23:02:56 < Ecco> I enjoy using it anyway, even though I have to agree that few pins are available
2015-07-12T23:03:13 < Ecco> Yeah that makes sense
2015-07-12T23:03:32 < Ecco> Do you have any idea who's their supplier for the LCD on the F7?
2015-07-12T23:03:48 < Tectu> Ecco, yes:  http://www.rocktech.com.hk/
2015-07-12T23:04:05 < Ecco> Sweet, thanks
2015-07-12T23:04:11 < Ecco> How did you figure it out?
2015-07-12T23:04:21 < Tectu> Ecco, they listed them as an official supplier.
2015-07-12T23:04:27 < Ecco> Oh ok :)
2015-07-12T23:04:37 < Ecco> Thanks!
2015-07-12T23:04:41 < Tectu> Ecco, and there was a cryptic number on the schematics that google didnt know but their site did
2015-07-12T23:04:49 < Ecco> oh ok :)
2015-07-12T23:05:24 < Taxman> Tectu: Why is the display quality of F729 DISCO bad? narrow viewing angle?
2015-07-12T23:05:58 < Tectu> Taxman, color reproduction too
2015-07-12T23:06:18 < Tectu> Taxman, viewing angles are always bad with these types of displays. The F7 has however quite a decent one in that regard to be honest
2015-07-12T23:06:51 < Steffanx> the colours are also terrible
2015-07-12T23:07:15 < Taxman> has anoyone already found a F746 errata sheet?
2015-07-12T23:07:22 < Steffanx> yes
2015-07-12T23:07:44 < Taxman> how bad is it?
2015-07-12T23:08:08 < Steffanx> http://www.st.com/st-web-ui/static/active/en/resource/technical/document/errata_sheet/DM00145382.pdf just in the list with ducs
2015-07-12T23:09:04 < Tectu> erratas are only bad when you are not man enough to ignore them
2015-07-12T23:09:52 < Tectu> (not being serious, in case of somebody didnt get that?
2015-07-12T23:10:41 < Taxman> there seem to be errors that already are in the F429/439
2015-07-12T23:11:31 < Steffanx> wouldnt be surprised if you can find errors in there that all F's have
2015-07-12T23:11:41 < Steffanx> after F1
2015-07-12T23:11:42 < Tectu> Btw, is that just my feeling or are 85% of STM32 erratas about Ethernet?

2015-07-12T23:18:30 < aandrew> BSP_LED_Toggle(LEDx); JESUS FUCK GOTTA FUCKING ADD A COMMENT STATING WHAT THIS LINE DOES, I AM JUST SO FUCKING CONFUSED
2015-07-12T23:19:29 < aandrew> incidentally why is the functip BSP_LED_Toggle? isn't toggle a GPIO function?
2015-07-12T23:24:05 < aandrew> more opinion based than anything, but I also hate it when people put lower-level functions beneath higher-level functions and then add explicit function declarations above so the compiler is happy
2015-07-12T23:27:51 < Steffanx> you must have a hard life than... im sure that happens a lot
2015-07-12T23:27:52 < Tectu> aandrew, GPIO toggle function requires both port and pin
2015-07-12T23:28:03 < Tectu> aandrew, the LEDx is a macro that they know the port and the pin from.
2015-07-12T23:28:28 < Laurenceb> Tectu: back
2015-07-12T23:28:40 < Tectu> Laurenceb, wb
2015-07-12T23:28:45 < aandrew> Tectu: right, I guess they call it BSP_LED because it's board specifc and there's an LED off there
2015-07-12T23:29:03 < Tectu> aandrew, you might want to check out arduino.cc
2015-07-12T23:29:08 < Tectu> aandrew, much simpler :)
2015-07-12T23:29:15 < Tectu> Laurenceb, got some smart ideas?
2015-07-12T23:30:09 < Laurenceb> did you read that page?
2015-07-12T23:30:19 < aandrew> Tectu: lol
2015-07-12T23:30:37 < aandrew> Tectu: don't confuse getting up to speed on a specific implementation with being a newb.
2015-07-12T23:30:53 < Tectu> Laurenceb, oh, forgot to do that. sorry, thought you came to my place when you wrote   bbl  :/
2015-07-12T23:30:55 < Tectu> Laurenceb, doing that now then
2015-07-12T23:31:16 < Laurenceb> I'd suggest looking at the stack
2015-07-12T23:31:28 < Tectu> aandrew, I am sure there are some pro developers that just have enough of the rage and due to that became arduino people
2015-07-12T23:31:44 < Tectu> Laurenceb, I am sorry, how do I do that? isnt  backtrace  exaclty that?
2015-07-12T23:31:54 < Laurenceb> I'm not quite sure
2015-07-12T23:32:04 < aandrew> actually arduino confuses me more than regular C; I'm used to doing things the "old fashioned" way and the assumptions that these easy languages make causes me trouble
2015-07-12T23:32:11 < Laurenceb> maybe it can get confused
2015-07-12T23:32:25 < Laurenceb> I think ive seen this once, when i called an invalid address
2015-07-12T23:32:51 < Laurenceb> so you must be calling an invalid address somewhere, but I'm not sure how to find out where
2015-07-12T23:33:29 < Tectu> Laurenceb, the thing I dont understand:   The hardfault is caused by INVSTATE. In the documentation it states that in that case PC will hold the address of the instruction that caused this problem. Then I put a breakpoint at HardFault_Handler but the address shown in the PC does not come up in the objdump -d file
2015-07-12T23:33:33 < Laurenceb> it _should_ be somewhere in the stack, but im not sure if the face that stacktrace is broken means that its not there, or just that stacktrace got confused
2015-07-12T23:33:48 < Laurenceb> interesting
2015-07-12T23:34:02 < Tectu> Laurenceb, http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.subset.cortexm.m3/index.html
2015-07-12T23:34:08 < Laurenceb> thats m3
2015-07-12T23:34:08 < Tectu> Laurenceb, INVSTATE at the bottom
2015-07-12T23:34:14 < Tectu> Laurenceb, no, the URL is fucked up
2015-07-12T23:34:17 < Tectu> Laurenceb, look at title
2015-07-12T23:34:17 < Steffanx> Laurenceb how useful is that script in your repo?
2015-07-12T23:34:42 < ReadError> Tectu how is the touch aspect of the f7 ?
2015-07-12T23:34:48 < Tectu> ReadError, very good.
2015-07-12T23:34:50 < ReadError> like feel/responsiveness
2015-07-12T23:34:55 < Tectu> ReadError, the touch controller chip even supports gestures
2015-07-12T23:34:58 < ReadError> similar to a cellphone?
2015-07-12T23:35:00 < Laurenceb> arg that site
2015-07-12T23:35:06 < ReadError> or more like the f4 disco one
2015-07-12T23:35:08 < Tectu> ReadError, well it has no hard glass surface...
2015-07-12T23:35:10 < Laurenceb> where in INVSTATE documented?
2015-07-12T23:35:26 < Tectu> Laurenceb, CFSR  Configurable Fault Status Register

2015-07-12T23:35:45 < Laurenceb> hmm
2015-07-12T23:35:53 < Laurenceb> i only see a very complex tree structure
2015-07-12T23:36:03 < Laurenceb> starting at ARM Cortex-M7
2015-07-12T23:36:21 < Tectu> Laurenceb, i posted the link :(
2015-07-12T23:36:29 < Tectu> Laurenceb, I know that the url is fucked up but that is official M7 doco
2015-07-12T23:36:40 < Tectu> ReadError, on a scale from 0 to 10 where 0 is the feel fo the F429iDiscovery board touchscreen and 10 is the feel of the F7Discovery touchscreen then we are at about a 10
2015-07-12T23:36:51 < Laurenceb> hmm not working for me
2015-07-12T23:37:04 < ReadError> lol Tectu
2015-07-12T23:37:13 < Tectu> Laurenceb, in the search bar, go for   All documents and search for   M7 INVSTATE
2015-07-12T23:37:34 < Tectu> ReadError, nah, the display and touchscreen is very good for the 50$ you pay
2015-07-12T23:37:34 < Laurenceb> aha
2015-07-12T23:37:39 < Tectu> Laurenceb, got it?
2015-07-12T23:38:15 < Tectu> ReadError, the only thing I use my F429i for is to throw it at the children that use(d) to play on the field behind my house.
2015-07-12T23:38:51 < Tectu> ReadError, the tantalum on there used to decouple the SDRAM makes quite a blow :)

2015-07-12T23:39:04 < ReadError> hah
2015-07-12T23:39:27 < Laurenceb> thats odd
2015-07-12T23:39:29 < Tectu> Laurenceb, wrong
2015-07-12T23:39:32 < Tectu> Laurenceb, INVSTATE is

2015-07-12T23:42:50 < Tectu> Laurenceb, what am I looking at_
2015-07-12T23:42:53 < Tectu> ?
2015-07-12T23:43:05 < Laurenceb> search for INVSTATE on there
2015-07-12T23:43:23 < Laurenceb> so either you called an invalid address that happened to contain some data
2015-07-12T23:43:40 < Laurenceb> or your code is screwed by GCC
2015-07-12T23:43:58 < Laurenceb> bbl
2015-07-12T23:44:06 < Tectu> Laurenceb, I guess GCC would complain that it cannot handle m7 when I pass cortex-m7 flag, right?
2015-07-12T23:44:19 < Laurenceb> dunno lol
2015-07-12T23:44:24 < Tectu> Laurenceb, I have latest GNU arm GCC
2015-07-12T23:44:26 < Tectu> Laurenceb, 4.9.x magic
2015-07-12T23:44:37 < Steffanx> so what causes this. your full app or just any app?
2015-07-12T23:44:48 < Tectu> Steffanx, any app that goes threading
2015-07-12T23:45:02 < Tectu> Steffanx, while said apps run fine on any other F4 and F1 crap
2015-07-12T23:45:08 < Tectu> even on windows...
2015-07-12T23:45:12 < Laurenceb> I think you need to grab your stack as a hex file
2015-07-12T23:45:17 < Laurenceb> and pastebin
2015-07-12T23:45:20 < Laurenceb> bbl 4 realz
2015-07-12T23:45:21 < Tectu> Laurenceb, how would I do that?
2015-07-12T23:45:24 < Tectu> Laurenceb, ok, cu
2015-07-12T23:45:25 < Laurenceb> GDB
2015-07-12T23:45:37 < Tectu> Laurenceb, you too :*
2015-07-12T23:46:28 < aandrew> hm, ok, so I un-comment the HAL_UART_MODULE_ENABLED define in hal_conf.h... it builds fine but when linking it can't find HAL_UART_Init()
2015-07-12T23:46:38 < Tectu> Laurenceb, http://paste.ugfx.org/show/8cc69814d7
2015-07-12T23:46:49 < aandrew> what magic is required to build the HAL_Uart crap
2015-07-12T23:47:03 < Tectu> aandrew, be careful, some HAL files come with _ex[.ch]  extensions too...
2015-07-12T23:47:17 < Tectu> aandrew, like rcc_ex.h and crap like that
2015-07-12T23:47:20 < Tectu> aandrew, dont ask me why...
2015-07-12T23:47:40 < aandrew> hm
2015-07-12T23:47:43 < aandrew> what are those for?
2015-07-12T23:47:56 < Tectu> aandrew, they contain stuff you need to use the ones without the _ex
2015-07-12T23:47:58 < aandrew> oh I see it
2015-07-12T23:47:59 < Tectu> aandrew, really, no idea.
2015-07-12T23:48:03 < aandrew> my makefile has to add it
2015-07-12T23:48:15 < Tectu> aandrew, they could have just thrown the _ex into the non _ex
2015-07-12T23:48:29 < Tectu> aandrew, got it working?
2015-07-12T23:49:12 < aandrew> there we go
2015-07-12T23:49:13 < aandrew> yep
2015-07-12T23:49:14 < aandrew> well
2015-07-12T23:49:21 < aandrew> it builds... have to see if it *works* now :-)
2015-07-12T23:49:28 < Tectu> hehe
2015-07-12T23:49:42 < Tectu> getting it built is always harder than getting it to work with STM32...
2015-07-12T23:49:45 < Tectu> at least I got that feeling
2015-07-12T23:49:49 < aandrew> steffen vogel's makefile is awesomesauce
2015-07-12T23:50:06 < Steffanx> Makefiles are never awesome
2015-07-12T23:50:09 < aandrew> well I always hated using these huge libraries, they always seem to do things in goofy ways
2015-07-12T23:50:32 < Steffanx> Yes ever checked ugfx makefiles? ;)
2015-07-12T23:50:49 < aandrew> no, out of fear
2015-07-12T23:51:33 < Tectu> aandrew, this is my makefile for STM32F4 and STM32Cube crap:  http://paste.ugfx.org/show/9b5a6a96e7

2015-07-12T23:52:30 < Tectu> Laurenceb, already did that

2015-07-12T23:52:32 < Tectu> Laurenceb, sec
2015-07-12T23:52:36 < Laurenceb> thats what you pasted
2015-07-12T23:52:38 < Laurenceb> failz
2015-07-12T23:52:58 < Laurenceb> does it hardfault at bootup?
2015-07-12T23:53:32 < Tectu> Laurenceb, nope, only when my delay inside a thread returns.
2015-07-12T23:53:53 < Tectu> Laurenceb, pasting -D now...
2015-07-12T23:54:03 < Laurenceb> you already pasted it
2015-07-12T23:54:08  * Laurenceb facepalm
2015-07-12T23:54:30 < Tectu> Laurenceb, this here is the GDB examine crap:   http://paste.ugfx.org/show/8cc69814d7
2015-07-12T23:54:36 < aandrew> Tectu: that looks very similar to what stv0g did
2015-07-12T23:55:02 < Tectu> aandrew, I created mine from scratch.
2015-07-12T23:55:26 < Tectu> aandrew, after writing 114 makefiles for uGFX you dont need to look at 3rd party makefiles no more ;)
2015-07-12T23:55:48 < Tectu> aandrew, and who on earth is stv0g?
2015-07-12T23:55:50 < Laurenceb> Tectu: you need a gdb macro
2015-07-12T23:56:04 < Tectu> Laurenceb, still pasting -D, 25k lines
2015-07-12T23:56:29 < Laurenceb> lulz
2015-07-12T23:56:34 < Laurenceb> I'm not going to read that
2015-07-12T23:56:41 < Tectu> Laurenceb, you asked for it
2015-07-12T23:56:41 < Laurenceb> you need GDB stack dump
2015-07-12T23:56:46 < Laurenceb> then compare to the asm
2015-07-12T23:56:56 < Laurenceb> so you can cross reference the addresses
2015-07-12T23:57:11 < Tectu> Laurenceb, sounds like a  job for somebody with time
2015-07-12T23:57:18 < Tectu> Laurenceb, somebody who got time because porn is banned in his country
2015-07-12T23:57:18 < Laurenceb> lol
2015-07-12T23:57:23 < Laurenceb> hahaha
2015-07-12T23:58:07 < Laurenceb> you should be able to create a loop in GDB... but surely this feature is built in
2015-07-12T23:58:14 < Laurenceb> I'll head to #gdb
2015-07-12T23:58:17 < aandrew> Tectu: I can absolutely believe it
2015-07-12T23:58:32 < aandrew> Tectu: stv0g is steffan vogel: https://github.com/stv0g/stm32cube-gcc
2015-07-12T23:58:39 < Tectu> aandrew, aah, thanks
2015-07-12T23:58:46 < Tectu> Laurenceb, thanks for your time and patience
2015-07-12T23:58:50 < Laurenceb> asking in #gdb
2015-07-12T23:58:57 < aandrew> hm, it seems like HAL_UART_MspInit() must have a default dummy function.
2015-07-12T23:58:57 < Laurenceb> it should be a common request
2015-07-12T23:59:04 < Laurenceb> stack -> hex dump
2015-07-12T23:59:17 < Tectu> aandrew, this is how your makefiles should look like:   https://bitbucket.org/Tectu/ugfx/src/cce83c62b1f26caaa4c5f196ea82b5784807020b/tools/gmake_scripts/compiler_gcc.mk?at=master
2015-07-12T23:59:36 < Tectu> Laurenceb, that a GDB command?
2015-07-12T23:59:45 < Laurenceb> no lolz

2015-07-13T00:00:58 < Laurenceb> will print the 'num' first elements of 'array[startindex]'.
2015-07-13T00:01:09 < Laurenceb> only you need the reverse
2015-07-13T00:01:33 < Laurenceb> but it should be simple to print the top <x> k bytes of memory

2015-07-13T01:05:54 < Laurenceb> first address i spot is line 37
2015-07-13T01:06:03 < Laurenceb> check for that in the dis asm
2015-07-13T01:06:22 < Laurenceb> no, 24
2015-07-13T01:06:23 < Tectu> Laurenceb, can you please tell me what I am currently looking at and what we are searching for?
2015-07-13T01:06:30 < Laurenceb> thats the stack
2015-07-13T01:06:41 < Laurenceb> we are searching for executable addresses
2015-07-13T01:06:49 < Laurenceb> pushed to the stack as return addresses
2015-07-13T01:07:12 < Tectu> Laurenceb, neither of the two is in the objdump -D
2015-07-13T01:07:30 < Tectu> doing ctrl+f here
2015-07-13T01:07:30 < Laurenceb> line 24 surely is
2015-07-13T01:07:41 < Laurenceb> miss off the last character
2015-07-13T01:08:23 < Tectu> Laurenceb, ctrl+f for   803cb60    no results found

2015-07-13T01:12:27 < Laurenceb> somethings wrong there
2015-07-13T01:12:39 < Laurenceb> unless its a variable

2015-07-13T01:13:13 < Tectu> Laurenceb, some  HAL and CMSIS
2015-07-13T01:13:30 < Steffanx> or jump to it and see if it makes sense?

2015-07-13T01:20:40 < Laurenceb> yes
2015-07-13T01:20:56 < Laurenceb> whatever is happening, its not too peedly nested
2015-07-13T01:21:02 < Laurenceb> or nested at all...
2015-07-13T01:21:27 < Laurenceb> is this FreeRTOS or ChibiOS?
2015-07-13T01:21:50 < Laurenceb> maybe you need some RTOS debug stuff, or maybe its storing stack elsewhere
2015-07-13T01:21:58 < Tectu> Laurenceb, no ChibiOS and no FreeRTOS, just basic setjmp/longjmp
2015-07-13T01:22:03 < Tectu> as mentioned multiple times before
2015-07-13T01:22:06 < Laurenceb> oh
2015-07-13T01:22:10 < Laurenceb> how do those work lol
2015-07-13T01:22:11 < Tectu> it works with ´normal´ programs
2015-07-13T01:22:22 < Tectu> Laurenceb, https://en.wikipedia.org/wiki/Setjmp.h
2015-07-13T01:22:25 < Laurenceb> just a big direct jump ?
2015-07-13T01:22:27 < Laurenceb> reading
2015-07-13T01:22:33 < Tectu> Laurenceb, basically saving context then jmp
2015-07-13T01:22:53 < Laurenceb> can you add debug to your jump then?
2015-07-13T01:23:05 < Laurenceb> so it shoves jump location into an array before jumping
2015-07-13T01:23:15 < Laurenceb> maybe that would catch a jump to nonsense address
2015-07-13T01:23:24 < Laurenceb> i suspect you are jumping somewhere bad at some point
2015-07-13T01:24:37 < Tectu> Laurenceb, just to clearify, works great on M0, M3 and M4
2015-07-13T01:24:59 < Laurenceb> _exact_ same code?
2015-07-13T01:25:04 < Tectu> exact same code
2015-07-13T01:25:06 < Tectu> same compiler
2015-07-13T01:25:14 < Tectu> same flags (beside m7 vs m4 flag)
2015-07-13T01:25:48 < Laurenceb> can you set a breakpoint at longjump?
2015-07-13T01:25:52 < Laurenceb> or is it inlined?
2015-07-13T01:26:14 < Laurenceb> maybe you could make it a function
2015-07-13T01:26:17 < Laurenceb> then break
2015-07-13T01:26:29 < Tectu> Laurenceb, https://bitbucket.org/Tectu/ugfx/src/cce83c62b1f26caaa4c5f196ea82b5784807020b/src/gos/gos_raw32.c?at=master#cl-612
2015-07-13T01:26:30 < Laurenceb> or set a global variable in you code called before it breaks
2015-07-13T01:26:38 < Tectu> Laurenceb, so no issue to break there
2015-07-13T01:26:39 < Laurenceb> then an if condition
2015-07-13T01:26:43 < Laurenceb> and break inside

2015-07-13T01:53:36 < zyp> I just woke up, haven't been following
2015-07-13T01:53:41 < Laurenceb> he cant debug a hardfault
2015-07-13T01:53:46 < zyp> ah
2015-07-13T01:53:52 < Laurenceb> nothing useful in backtrace
2015-07-13T01:54:06 < Laurenceb> we tried dumping the stack, it has no sane flash addresses
2015-07-13T01:54:16 < Laurenceb> cant work out where his code is failing
2015-07-13T01:54:20 < zyp> nothing useful in CFSR? or is this M0?
2015-07-13T01:54:24 < Laurenceb> M7
2015-07-13T01:54:28 < zyp> oh, right
2015-07-13T01:54:32 < Laurenceb> invalid instruction
2015-07-13T01:54:39 < Laurenceb> just a sec, its in backscroll
2015-07-13T01:55:12 < Laurenceb> INVSTATE causes Hardfault handler to be entered
2015-07-13T01:55:19 < Laurenceb> but no useful backtrace/stack
2015-07-13T01:56:12 < Laurenceb> any idea whats wrong?
2015-07-13T01:57:04 < zyp> hmm, INVSTATE is usually caused by trying to execute arm instructions on thumb-only
2015-07-13T01:57:15 < zyp> I assume M7 is still thumb-only?
2015-07-13T01:57:30 < zyp> no, wait, not arm instructions
2015-07-13T01:57:35 < zyp> but jumping to arm mode
2015-07-13T01:58:28 < zyp> then again, if the stack doesn't make sense, maybe that's just a result of a stack corruption
2015-07-13T01:59:41 < zyp> if a function pushes lr, messes up the stack, and then tries to pop it into pc or something, getting a different value than lr, it might be interpreted as an attempted switch to arm mode and cause INVSTATE
2015-07-13T02:00:07 < zyp> and since the stack is messed up, backtrace doesn't make sense
2015-07-13T02:01:49 < zyp> the current pc value should still be sane in that case, and point to the violating instruction, which might be «pop <…, pc>» or similar
2015-07-13T02:02:14 < zyp> or maybe not, I forget if that get rolled back

2015-07-13T02:58:11 < karlp> why wasn't tectu just using the vecstate gdb script like he was told? why did he spend hours dicking around trying to do it all by hand?
2015-07-13T02:59:30 < zyp> idk
2015-07-13T02:59:57 < karlp> holy fyuck tectu, go and copy the "verbose" build stuff form the libopencm3 makefiles instead of your glorious if else cases, where you end up having a different damn compile command in each case if you ever make a mistake
2015-07-13T03:00:16 < zyp> haha
2015-07-13T03:00:44 < zyp> I don't get the desire for quiet builds
2015-07-13T03:01:24 < zyp> either all the shit scrolls past without you caring because everything works, or you want to know what exactly happened
2015-07-13T03:02:18 < zyp> I have to admit the percentage thing in cmake generated stuff is a bit cute though, when you are building huge shit
2015-07-13T03:02:49 < karlp> about the only nice thing about cmake
2015-07-13T03:03:18 < zyp> heh
2015-07-13T03:03:35 < zyp> I thought the nicest thing about cmake is that it isn't autoconf/automake
2015-07-13T03:03:45 < karlp> yeah, tectu's crash is most likely stack blowup, given he's written his own longjmp stjmp stuff and ended up in invstate
2015-07-13T03:03:55 < zyp> oh, right
2015-07-13T03:04:07 < karlp> so he's probably not hitting the first error, but the details are gone by the time he ends up in hardfault
2015-07-13T03:04:16 < zyp> yeah
2015-07-13T03:04:18 < karlp> been there, done that.
2015-07-13T03:04:33 < karlp> still no fucking clue why he didn't just run the vecstate script like he was told...
2015-07-13T03:04:42 < zyp> would it help?
2015-07-13T03:04:52 < karlp> no, but it would have told him invstate way way faster :)
2015-07-13T03:04:57 < zyp> SCB doesn't really tell anything more useful than INVSTATE in that case then?
2015-07-13T03:05:47 < karlp> don't remember, wasn't goign to dig through all of it now :)

2015-07-13T03:30:37 < Laurenceb> ah yeah
2015-07-13T03:30:49 < dongs> it probly fits into reduced-size so8 footprint heh
2015-07-13T03:30:53 < Laurenceb> hmm maybe i could compress somehow
2015-07-13T03:31:00 < Laurenceb> its just temperature data

2015-07-13T03:37:22 < aandrew> dongs: setting up stm32cube shit with freertos with just a makefile (no ide bullshit) was actually not too bad
2015-07-13T03:37:58 < aandrew> dongs: that SPI flash is pretty standard. I have a footprint that accepts DFN-EP or SOIC to get the best of both worlds
2015-07-13T03:38:54 < aandrew> I've used microchip's spi flash in dfn8, second sourced with SST and Marconix
2015-07-13T03:39:32 < dongs> right, thats the big ones
2015-07-13T03:39:35 < dongs> he wanted somethign smaller
2015-07-13T03:39:44 < dongs> looks like that 2x3 thing is standard across at least 3 vendors
2015-07-13T03:41:32 < Laurenceb> thanx for link
2015-07-13T03:41:41 < Laurenceb> hmm maybe i should look at wavelet compression

2015-07-13T03:42:45 < Laurenceb> bet with wavelets i could get it down to 512bytes/hour

2015-07-13T06:36:53 < dongs> i guess now i can talk even more shit about them

2015-07-13T06:41:27 < upgrdman> mmm
2015-07-13T06:41:41 < zyp> hey, I can attest that they've at least got one sale due to that
2015-07-13T06:42:47 < zyp> I'm prtty happy with the F4 board I've got
2015-07-13T06:42:55 < dongs> :D
2015-07-13T06:43:23 < zyp> but I'm not too impressed by the newer bullshit they are doing with separate core and breakout boards
2015-07-13T06:43:31 < zyp> that just seems pointless
2015-07-13T06:43:39 < dongs> saves them cost probly

2015-07-13T06:43:59 < dongs> but then again, all their stuff is 2L, so probably not so
2015-07-13T06:45:28 < zyp> btw, I was talking with karlp earlier about making a board for automated testing of drivers and shit across the stm32 range
2015-07-13T06:46:02 < dongs> drivers?
2015-07-13T06:46:26 < zyp> just slap a bunch of chips on a board along with a debugger with the ability to control power to them, then interconnect all the chips so you can test comms between them

2015-07-13T06:46:42 < zyp> then everything can be scripted for automated testing
2015-07-13T06:47:06 < zyp> shit like my lib, usb stack, whatever, and comparable stuff like libopencm3
2015-07-13T06:47:45 < zyp> it'd be nice to have an automated way of verifying that changes to some code doesn't break functionality on other chips
2015-07-13T06:48:21 < zyp> I've considered writing test cases before that runs on the discovery boards, but you don't really get to test a lot of comms that way
2015-07-13T06:48:32 < zyp> without hooking up a ton of bullshit
2015-07-13T06:48:46 < zyp> so I'm considering making a self-contained test board
2015-07-13T06:53:14 < dongs> what would it achieve as opposed to -discovery
2015-07-13T06:53:20 < dongs> cuz some of hte peripherals are overused on them?

2015-07-13T06:54:01 < zyp> well, you can't really test uart code on a discovery, because there's nothing hooked up to any
2015-07-13T06:54:23 < zyp> I'm thinking about a board with interconnected uarts, interconnected spi, i2c, etc…
2015-07-13T06:54:30 < dongs> ahh loopback
2015-07-13T06:54:30 < dongs> right
2015-07-13T06:54:42 < zyp> not really loopback, but chip to chip
2015-07-13T06:55:29 < zyp> the idea is to automate everything so this can be ran automatically, CI style
2015-07-13T06:55:37 < zyp> just leave a board hooked up on a shelf somewhere
2015-07-13T06:55:54 < dongs> one mcu doesn't get updated?
2015-07-13T06:56:01 < dongs> just the other one thats being "tested"?
2015-07-13T06:56:34 < zyp> I'm imagining a bunch of builds being done that's testing each other in various combinations
2015-07-13T06:56:53 < zyp> think of it like a sanity check, if any tests fail, something is wrong and then you can look at it manually

2015-07-13T12:57:06 < jpa-> are you using a newish one?
2015-07-13T12:58:14 < Tectu> jpa-, GNU ARM GCC 4.9.3
2015-07-13T12:58:58 < Tectu> jpa-, objdump is  2.24.0.20150304
2015-07-13T13:00:18 < decimad> Tectu: Can you recommend a cheap display I could connect to my STM32F4-Board (not discovery) that works with your library? I'd like graphics support and your library seems to be cool!
2015-07-13T13:00:51 < Tectu> decimad, thanks, glad to hear that :)
2015-07-13T13:00:59 < Tectu> decimad, what F4 board do you have?
2015-07-13T13:01:12 < Tectu> decimad, and what size are you thinking about?
2015-07-13T13:01:42 < decimad> XCore 407i from waveshare
2015-07-13T13:01:59 < Tectu> decimad, do you happen to have the waveshare base board mother board thingy?
2015-07-13T13:02:07 < decimad> No, just the bare board
2015-07-13T13:02:16 < decimad> had to do custom debugger wiring too
2015-07-13T13:02:54 < Tectu> decimad, these ones are quite good for the price:  http://www.ebay.com/itm/3-2-LCD-Module-Display-Touch-PCB-262K-Colors-screen-SSD1289-for-Arduino-/321534318476?pt=LH_DefaultDomain_2&hash=item4adcf0578c
2015-07-13T13:03:10 < Tectu> decimad, also 100% uGFX support on those drivers there (display and touch)
2015-07-13T13:03:31 < decimad> Great, I'll order one of those ;)
2015-07-13T13:03:57 < Tectu> decimad, wait
2015-07-13T13:04:01 < Tectu> decimad, there are others too :)
2015-07-13T13:04:18 < Tectu> decimad, if you want higher resolution / bigger size search for SSD1963 on ebay
2015-07-13T13:04:19 < Tectu> decimad, http://www.ebay.com/itm/4-3-inch-4-3-TFT-LCD-Display-Module-SSD1963-480x272-With-Touch-Panel-SD-Card-/311161631620?pt=LH_DefaultDomain_0&hash=item4872adb384
2015-07-13T13:04:28 < Tectu> decimad, also fully supported :)
2015-07-13T13:05:09 < decimad> even better :)
2015-07-13T13:05:53 < Tectu> decimad, there are SSD1963 modules out there with 640x480 or even 800x480

2015-07-13T13:07:31 < Tectu> decimad, you happen to use FreeRTOS, right?
2015-07-13T13:07:36 < decimad> Tectu I think you need to stay below some 27euros or something to get past the tax?
2015-07-13T13:07:49 < decimad> Tectu no, chibios, but you support that one too, I read ;)
2015-07-13T13:07:57 < Tectu> decimad, that depends on your country, no idea
2015-07-13T13:08:02 < decimad> Tectu germany ;)
2015-07-13T13:08:13 < Tectu> decimad, just order it through greece and you are good to go
2015-07-13T13:08:29 < Tectu> decimad, nah, I have no idea, sorry. Here it is everything sub 50eur is good
2015-07-13T13:08:53 < Tectu> decimad, but those ebay people always ship it as a gift, so no taxes anyway. At least here
2015-07-13T13:09:28 < decimad> Tectu well, I'd find so many gifts suspicious if I where the customs ;)

2015-07-13T16:25:01 < jpa-> isn't that just boost + 3V micro?
2015-07-13T16:25:16 < Laurenceb> yeah

2015-07-13T16:25:26 < Laurenceb> MSP is 0.9v

2015-07-13T16:26:46 < Laurenceb> cuz it needs 1.8v

2015-07-13T16:27:31 < Laurenceb> yeah but lame
2015-07-13T16:28:03 < Taxman> maybe the zinc air cell can not supply enough current for core i7

2015-07-14T01:35:04 < Rickta59> and was wondering if ugfx would do anything with it
2015-07-14T01:35:41 < Tectu> we dont care about the type of display you are using. You just have to implement a very basic interface
2015-07-14T01:35:46 < decimad> rkreis: that would be something along the lines I'm thinking: https://github.com/decimad/microptp/blob/master/util/fixed2test.cpp
2015-07-14T01:35:49 < Tectu> most basicially you just need init() and setPixel()
2015-07-14T01:36:06 < Rickta59> is it an optimized thing .. or something meant to be generic?
2015-07-14T01:36:11 < decimad> rkreis: no trigonometrics ;)
2015-07-14T01:36:17 < Tectu> Rickta59, there are about 30 drivers available including documentation on our wiki page about the different display driver models that exist.
2015-07-14T01:36:46 < Tectu> Rickta59, ugfx is very scalable. it runs from the most basic implementation and allows you to optimize what ever possible. We have interfaces for hardware acceleration etc.
2015-07-14T01:36:54 < Rickta59> k thanks
2015-07-14T01:36:57 < Tectu> Rickta59, Taxman might give some feedback at this point
2015-07-14T01:37:07 < Rickta59> i'll just download it and try it

2015-07-14T01:37:54 < Tectu> Rickta59, what display driver do you have on that display module?
2015-07-14T01:37:57 < Taxman> with a SSD?
2015-07-14T01:38:08 < Rickta59> it is the TI kentec booster
2015-07-14T01:38:09 < Tectu> Taxman, probably just some old harddrive, no SSD yet

2015-07-14T01:38:33 < Tectu> Rickta59, dont have a built-in driver for that yet. But writing your own driver is more or less easy when you know your C.
2015-07-14T01:39:14 < Tectu> Rickta59, as mentioned, there are already many existing driver implementation ranging from small monochromes to full framebuffer drivers. And the wiki article about the display driver model helps
2015-07-14T01:39:23 < Tectu> Rickta59, http://wiki.ugfx.org/index.php?title=Display_Driver_Model
2015-07-14T01:39:27 < Rickta59> https://store.ti.com/boostxl-k350QVG-s1.aspx that one
2015-07-14T01:41:24 < Tectu> Rickta59, that module uses an SSD2119 driver
2015-07-14T01:41:31 < Tectu> Rickta59, we already have a driver for that in the uGFX repository
2015-07-14T01:41:37 < Rickta59> great thanks
2015-07-14T01:41:47 < Tectu> Rickta59, including all the available hardware acceleration on that driver
2015-07-14T01:41:55 < Rickta59> even better
2015-07-14T01:42:11 < Tectu> Rickta59, all you have to do is implement this interface:  https://bitbucket.org/Tectu/ugfx/src/8b60b516231dee99f9e5df6b3398b4279568f6bb/drivers/gdisp/SSD2119/board_SSD2119_template.h?at=master

2015-07-14T01:42:56 < Tectu> Rickta59, that module uses an SPI interface, so providing that you have some ready working examples it should be quite easy. the DMA stuff at the bottom is optionally as you can see
2015-07-14T01:43:17 < Rickta59> that was a link in the template code

2015-07-14T01:48:03 < Tectu> cu folks
2015-07-14T01:49:12 < Tectu> Rickta59, btw, http://studio.ugfx.org
2015-07-14T02:00:57 < decimad> Tectu: what's the native app good for? :)
2015-07-14T02:01:31 < decimad> is this a test wether the generated source compiles?
2015-07-14T02:01:40 < Tectu> decimad, that is a windows/linux/osx application that runs the real uGFX code. this way you get a 1:1 example with 100% accuracy of what the GUI will look like on our microcontroller
2015-07-14T02:01:56 < Tectu> decimad, the generated code is supposed to alway compile ;)
2015-07-14T02:02:08 < decimad> well, it might not in cases ;)
2015-07-14T02:02:36 < Tectu> decimad, the thin is that the drag-n-drop scene is just a close match to the real result. not everything is accurate in pixel counts etc. There are small differences. the live preview gives you the real thing
2015-07-14T02:02:58 < Tectu> decimad, you can obviously use it to verify that it compiles too ;)
2015-07-14T02:03:23 < decimad> I would really prefer if the designer already uses the ugfx primitives and correct coordinates ;)
2015-07-14T02:04:05 < decimad> But I guess you use QT drawing there?
2015-07-14T02:04:29 < Tectu> decimad, correct
2015-07-14T02:04:45 < Tectu> decimad, it is a question of time. The list widget which I added the last is very accurate
2015-07-14T02:04:56 < Tectu> decimad, previously it was important to get this thing up and running
2015-07-14T02:05:14 < Tectu> decimad, sizes etc. are correct, but issues can occur due to float rounding and anti-aliasing
2015-07-14T02:05:28 < decimad> Well okay... I just guess, if you have the tech to do the drawing from the generated source... you could also do it in first place ;)
2015-07-14T02:05:39 < Tectu> decimad, not so easy
2015-07-14T02:05:55 < Tectu> decimad, you would have to port ALL the drawing code to qt etc
2015-07-14T02:06:15 < decimad> There must be a framebuffer-alike thingy in QT?
2015-07-14T02:06:45 < decimad> Then QT would look like a driver to ugfx... maybe
2015-07-14T02:06:50 < Tectu> decimad, well, I started using QGraphicsItem
2015-07-14T02:06:56 < decimad> Just thinking... :)
2015-07-14T02:07:14 < Tectu> decimad, I wrote this thing in one year of my spare time. 25k lines of code. I am pretty happy with how far it got in that time :P
2015-07-14T02:07:38 < Tectu> decimad, I will definitely put more time into having a more accurate result but the renderings are already very accurate, the live preview just gives you the full 100%.
2015-07-14T02:07:58 < decimad> Yes, I'm just nitpicking, of course a visual designer is better than none... I was just thinking about going back and forth between designer and native app
2015-07-14T02:08:49 < Tectu> decimad, I am using QGraphicsScene and QGraphicsView. this includes all the magic to drag QGraphicsItems around etc. context menu and move events, resizing, all done.
2015-07-14T02:09:06 < Tectu> decimad, when I go framebuffer it will be a lot of hacking to have the interactive aspect
2015-07-14T02:10:12 < Tectu> decimad, if you can think of a solution that might work without a lot of hacking I am all ears :)
2015-07-14T02:10:15 < decimad> Ah okay... yeah. Well, I guess one could derive the visual and interactive components from the ugfx components and just let them handle user input, but leave drawing to the ugfx classes which in turn use the ugfx-QT-driver...
2015-07-14T02:10:34 < Tectu> decimad, that would be pretty neat
2015-07-14T02:12:40 < decimad> But it always sounds simpler than it ends up being ;)

2015-07-14T02:12:53 < decimad> that's the lesson I learned... if any
2015-07-14T02:14:22 < decimad> So you're into C++ as well? Did you have a look at the sample code I linked earlier maybe? I wonder if using the compiler for fixed-point-related calcs and type stuff is really as helpful as it feels to me... or if I'm just not good enough at it ;)

2015-07-14T05:57:58 < zyp> that's normal
2015-07-14T06:01:38 < zyp> I mean, even you have to be used to keys with three symbols

2015-07-14T06:02:00 < zyp> and then there's the fourth shift+altgr+press
2015-07-14T06:02:14 < zyp> it's not even unique to mac
2015-07-14T06:02:37 < jadew> what's unique to mac is that they managed to put all the labels on each key

2015-07-14T08:36:15 < dongs> sounds abou right
2015-07-14T08:36:19 < dongs> anyawy, they're all available im sure
2015-07-14T08:36:32 < talsit> what does the neo have the max doesn't?
2015-07-14T08:36:50 < dongs> one of them requires external eep for stuff
2015-07-14T08:36:52 < dongs> forget which one
2015-07-14T08:37:09 < dongs> also i only dicked with 6/7 series, and apparently 8 series is new/current now
2015-07-14T08:37:43 < gxti> i don't know how they compare, i just know neo was the most cost-effective for what i was doing
2015-07-14T08:37:59 < talsit> there's on my NEO8, max is still 7
2015-07-14T08:38:05 < talsit> (from their websites)
2015-07-14T08:40:53 < talsit> right, the NEO series has SPI

2015-07-14T09:46:50 < talsit> wtf? $60/ea for a uBlox MAX7C?!
2015-07-14T09:48:45 < _Sync_> yeah
2015-07-14T09:49:19 < talsit> ublox lists them as $49 on their online shop
2015-07-14T09:50:05 < _Sync_> yeah I don't get why they are so srs expensive after all
2015-07-14T09:50:32 < talsit> that's for single qty, if you want 250+, they're like $10 on their webshop
2015-07-14T09:51:13 < _Sync_> that's more reasonable
2015-07-14T09:52:06 < talsit> but this reseller wants me to pay more than what it would cost me to buy them from ublox direct, and with 4 week lead time
2015-07-14T09:52:26 < _Sync_> I used some other gnss chipset because they were annoying to get for my company for whatever reason

2015-07-14T11:00:42 < decimad> hrmmm, can you somehow tell gcc to align something to 2 bytes, but always on "uneven" addresses... ie. adding  if something is aligned to 4 bytes and contains an array of this, it would add 2 bytes padding before the array? (and obviously the array elements will have to be sized in 4 byte multiples as well
2015-07-14T11:03:53 < specing> I guess it is possible by defining a new section and putting the data there
2015-07-14T11:04:03 < specing> then using some linker magic
2015-07-14T11:04:44 < decimad> hrmmm, I could add the 2 byte padding myself and specify attribute packed

2015-07-14T11:15:29 < jpa-> yeah, or other way is to allocate 2 extra bytes of memory and then do   myptr = memory; if (myptr % 4 == 0) myptr += 2;
2015-07-14T11:20:03 < decimad> but I don't know what happens if I specify packed for a struct but it contains elements that are not specified packed... does the packed overrule nested alignment requirements?
2015-07-14T11:22:30 < GargantuaSauce> i see bus errors in your future
2015-07-14T11:23:00 < decimad> Gnarf... this proves more difficult to tell the compiler... my array elements are basically structs with a std::aligned_storage of buffer size, which can either contain a buffer (any object really) or a next/prev pointer. Obviously I need the next/prev to be aligned, but the buffer needs not to be... So I need to parametrize the elements for the padding as well... which makes element pointers dependent on the padding as well :(
2015-07-14T11:23:40 < GargantuaSauce> why does the buffer have to be unaligned
2015-07-14T11:23:41 < decimad> GargantuaSauce I'm just trying to get ethernet packets aligned to 2 odd, for the ip payload to be aligned to 4 bytes
2015-07-14T11:23:49 < GargantuaSauce> ahh
2015-07-14T11:24:36 < decimad> and i'd like 1x padding instead of n times
2015-07-14T11:25:29 < GargantuaSauce> i think pad & packed is the way to go
2015-07-14T11:25:43 < GargantuaSauce> as long as you use ->/. to access unaligned members it'll be fine
2015-07-14T11:26:11 < GargantuaSauce> but of course *((int*)0x*******2) or dma or whatever will break

2015-07-14T13:24:35 < Tectu> Taxman, this benchmark shows an F407 with an SSD1289 connected over 16-Bit FSMC:  https://www.youtube.com/watch?v=WcNgBEWWnrc

2015-07-14T16:57:42 < stukdev> about bootloder in stm32f4, i try using code for booting from code, but don't work. I read sometime about a special register of cpu, where i can set a bit an read at startup. Somebody can tell me more information about this register'
2015-07-14T16:57:43 < stukdev> ?
2015-07-14T16:58:00 < dongs> you can use a variety of things
2015-07-14T16:58:05 < dongs> BKP ram is one option
2015-07-14T16:58:17 < dongs> also just an arbitrary byte in ram as long as you read it before your bss is cleared
2015-07-14T16:58:36 < stukdev> dongs: ram? is not delete after reset?
2015-07-14T16:58:42 < dongs> nope :)
2015-07-14T16:58:47 < dongs> its clearead by startup code

2015-07-14T16:58:53 < dongs> so..
2015-07-14T16:58:58 < dongs> if you read it before it does that
2015-07-14T16:59:00 < dongs> then it sfine
2015-07-14T16:59:16 < stukdev> otherwise this backup register? its permanent?
2015-07-14T16:59:24 < dongs> permanent as long as it has power sure
2015-07-14T16:59:28 < dongs> look up BKP stuff in RM
2015-07-14T17:00:26 < stukdev> dongs: so its not "permanent" the backup is not really a backup :D
2015-07-14T17:00:40 < dongs> it is powered by VBAT/RTC domain
2015-07-14T17:00:59 < dongs> you asked for a way to store value across reset
2015-07-14T17:01:00 < dongs> i told you
2015-07-14T17:01:40 < Laurenceb> Zano shipped 4 realz?
2015-07-14T17:01:46 < scrts2> yep
2015-07-14T17:01:51 < dongs> Laurenceb: why dont you drive down to their offices
2015-07-14T17:01:52 < dongs> and ask
2015-07-14T17:01:55 < stukdev> dongs: mmm i read "If you will try working with backup SRAM on STM32F401" its true?
2015-07-14T17:02:04 < dongs> ?
2015-07-14T17:02:08 < stukdev> *If you will try working with backup SRAM on STM32F401 or STM32F411 devices, you will get “HardFault” error when you will try to read from backup SRAM register locations.
2015-07-14T17:02:17 < dongs> pretty sure every stm32 has BKP stuff
2015-07-14T17:02:20 < dongs> F`1/F4 does
2015-07-14T17:02:28 < stukdev> These devices don’t have backup SRAM inside so do not try to do that or your device can stuck.
2015-07-14T17:02:28 < stukdev> Also, not available on any STM32F4 Nucleo board.
2015-07-14T17:02:29 < dongs> why dont tyou read the god damn reference manual
2015-07-14T17:02:31 < Laurenceb> but nobody has one yet?

2015-07-14T17:05:52 < stukdev> dongs: i just downloaded
2015-07-14T17:06:44 < stukdev> dongs:  its say 20 backup registers
2015-07-14T17:06:48 < dongs> yep.
2015-07-14T17:06:55 < dongs> you only need to use any of them.

2015-07-14T17:14:09 < karlp> read the doc better.
2015-07-14T17:14:41 < dongs> the time you spent asking dumb questions and googling forums you could have already written the ~3 lines of code needed to turn BKP on, write a byte into them, and another 2 lines needed to read it on reboot
2015-07-14T17:15:39 < stukdev> i don't think so :)

2015-07-14T18:12:19 < decimad> Is input with pull-up activated + push-button with large resistor vs. gnd okay? my electronics suck...
2015-07-14T18:12:53 < Tectu> decimad, usually you have an input with pull-up and just a switch going from the pin to ground
2015-07-14T18:13:34 < decimad> Is the pull-up-resistor enough to limit the current vs. ground?
2015-07-14T18:13:37 < Tectu> decimad, and when doing some crazy stuff you add a small cap (10 to 100nF) parallel to the switch and a 1k to 10k resistor in series to the GPIO line
2015-07-14T18:13:57 < gxti> "limiting" might be understating it
2015-07-14T18:14:07 < gxti> internal pullups are 100k+ so the current with button down is miniscule
2015-07-14T18:14:18 < decimad> oh great! I never saw number stated
2015-07-14T18:14:28 < Tectu> decimad, they are in the chips datasheet
2015-07-14T18:14:30 < byves> karlp: i've been through lots of docs from st.. they actually have a function HAL_RTCEx_GetWakeUpTimer but it returns the Wake-Up Timeout i've previously configured..gee
2015-07-14T18:14:53 < decimad> Great, so push-button vs. gnd without resistor, even better ;)
2015-07-14T18:15:01 < karlp> yeah, you're in the death cube there byves, no help for you

2015-07-14T18:15:58 < gxti> you *can* put a resistor to ground, but not much more than 1k because it's effectively a voltage divider and you won't get a clean 0 signal. i only would if you need extra robustness against emi/esd
2015-07-14T18:16:14 < karlp> oh Tectu, in case you missed it.  You need to learn about VAR ?= default value in makefiles, instead of your sea of ifeq calls
2015-07-14T18:16:33 < gxti> lol...
2015-07-14T18:16:49 < karlp> and look at libopencm3 or openwrt or similar for how to do verbose builds, you'r current system uses completely different compiler command lines, maintained by hand,
2015-07-14T18:17:05 < karlp> so one day you're goign to fuck up and a verbos ebuild will do a different thing to a non verbose build, and you will cry.
2015-07-14T18:17:15 < karlp> it will also make your makefile much much much simpler
2015-07-14T18:18:47 < Tectu> karlp, thanks for the hint. I indeed wish I knew ?= before. I learned about that a couple of weeks ago.
2015-07-14T18:19:27 < Tectu> karlp, I put that on the todo list, thanks. Can you give a short explanation what might go wrong and how others do it?
2015-07-14T18:20:32 < karlp> https://github.com/libopencm3/libopencm3/blob/master/Makefile#L44-L48 and then just the $(Q) prefix on each line...

2015-07-14T18:21:00 < karlp> you have the compiler command line twice, once for each verbose setting, and you'll make a change in only one of them one day
2015-07-14T18:21:02 < Tectu> decimad, thanks. When I told you to remind me I meant next monday, sorry ;P
2015-07-14T18:21:32 < Tectu> karlp, I understand. that is indeed a better solution

2015-07-14T18:55:34 < decimad> Well, maybe not at the targetted frequencies in an affordable way
2015-07-14T18:55:58 < Tectu> decimad, the PSoC crap has configurable OpAmp and stuff
2015-07-14T18:56:05 < Tectu> decimad, one could say it is an analog version of an FPGA...
2015-07-14T18:56:11 < Tectu> but that is just a rough comparasion
2015-07-14T18:56:19 < decimad> But it has only two?
2015-07-14T18:56:44 < decimad> Is there some time multiplexing going on to simulate passive electric components?
2015-07-14T19:00:14 < decimad> What I was thinking was actually an FPGA that can take like 1W of thermal power and is "degraded" to only electronically connect all possible combinations of pins... So you could connect Pins 1,6,256 and the others in some way

2015-07-14T20:04:25 < dongs> wavesahre cp2102 breakouts are pretty cheap for resellers
2015-07-14T20:04:39 < dongs> and they dont look completely fucking awful like the $.99 ebay ones
2015-07-14T20:04:47  * dongs gets a bunch
2015-07-14T20:05:26 < karlp> there's a few different ebay sellers, some of them ar ebetter than others, all cost about the same
2015-07-14T20:05:46 < dongs> ya
2015-07-14T20:05:54 < karlp> I have some that includ eheaders for the rest of the pins, and where the silk is still legible after connecting leads, those are better,
2015-07-14T20:06:07 < karlp> I've got some shitty ones that have silk underneath right angle headers => fail.
2015-07-14T20:06:15 < dongs> heh
2015-07-14T20:08:46 < karlp> nice how waveshare has them with both USB A and with usb mini B though
2015-07-14T20:09:06 < karlp> I ended up having to buy some usb extension cables to deal with all these boards with usb a plugs on them
2015-07-14T20:10:07 < _Sync_> lel
2015-07-14T20:12:13 < _Sync_> karlp: is there a reason why to use waveshare trash instead of ftdi trash?

2015-07-14T20:12:33 < karlp> waveshare sells ftdi, cp210x and pl2303, take your pic
2015-07-14T20:12:40 < karlp> waveshare is jsut a board seller
2015-07-14T20:12:46 < dongs> i'll only stock 2102, ftdi is aids
2015-07-14T20:12:50 < dongs> PL2303 is complete aids
2015-07-14T20:12:58 < karlp> cp210x is often cheaper than ftdi, at least in the past, the new ft230? whatsit are much cheaper
2015-07-14T20:13:03 < karlp> and pl2303 is aids, as mantioned
2015-07-14T20:13:10 < karlp> ch340/ch341 is also pretty aids
2015-07-14T20:13:24 < karlp> pl2303hx is meant to be "sane" again, but they got a bad rep for quite a while
2015-07-14T20:13:28 < dongs> i think 2303 aids-ness is mostly due to some awful knockoffs
2015-07-14T20:13:34 < karlp> yeah, likely
2015-07-14T20:13:47 < _Sync_> I have not had too much issues with ftdi
2015-07-14T20:13:51 < karlp> at one stage they were caling themselves 2303 and using ftdi's vid/pid stuff and all sorts of fail
2015-07-14T20:13:53 < _Sync_> besides them being the cancer as a company
2015-07-14T20:14:09 < karlp> ftdi works, but yeah, the company, and the older ft232rl was kinda pricey
2015-07-14T20:14:26 < dongs> probemaster shipped
2015-07-14T20:17:09 < PeterM> also what is that dumbfuck ftdi qfn with the leadframe partlyu exposed? thats aids too
2015-07-14T20:17:28 < dongs> CP2104 is the future
2015-07-14T20:17:36 < dongs> is there any smaller FTDI?
2015-07-14T20:19:18 < karlp> the new ones are much smaller than the old, and don't need crystals
2015-07-14T20:19:37 < karlp> we actually switched to them for a board at work, the manufacturing dudes could get them cheaper than cp2104
2015-07-14T20:19:42 < karlp> at least in our volumes...
2015-07-14T20:21:19 < karlp> ft230x is in qfn16, vs qfn24 for cp2104?
2015-07-14T20:22:32 < karlp> hrm, both 4x4mm nominal, just bigge rpitch on ft230x
2015-07-14T20:23:18 < dongs> err
2015-07-14T20:23:28 < Steffanx> what did you pay for shipping dongs?
2015-07-14T20:23:52 < dongs> CP2104 is cheaper than FT230XQ-R on digikey

2015-07-14T20:24:42 < dongs> $6.25 or someshit
2015-07-14T20:24:50 < Steffanx> emailed them?
2015-07-14T20:24:51 < karlp> and it doesn't require an extra cap on board and some shitty sw to reprogram the cp2104's rs485 driver mode in OTP

2015-07-15T02:54:09 < upgrdman_> a simple RC low-pass filter is -3dB per decade, right? so if you setup the filter for a 1kHz cut-off frequency, then it would be -3dB at 1kHz, -6dB at 10kHz, -9dB and 10kHz... right?
2015-07-15T02:54:39 < upgrdman_> and does -3dB mean 50% of the voltage or 50% of the power?

2015-07-15T07:12:44 < dongs> CE?
2015-07-15T07:12:47 < jpa-> i don't think there is any central registry for those
2015-07-15T07:12:51 < dongs> huh really
2015-07-15T07:12:56 < dongs> so how do eurofags work then
2015-07-15T07:13:03 < dongs> just sell shit illegally i bet
2015-07-15T07:13:07 < englishman> like UL? you just get listed
2015-07-15T07:13:12 < jpa-> CE mark you can just slap on a device, you only need to have the measurement data when they come asking for it :P
2015-07-15T07:13:50 < dongs> what is zano waiting for hten
2015-07-15T07:13:54 < jpa-> yeah, some companies spend a lot of time trying to follow the requirements, others just slap CE on the device as the sanctions for non-compliance are quite small
2015-07-15T07:15:00 < englishman> so its in their interest to fail a nonexistant cert
2015-07-15T07:15:35 < englishman> jpa-: you can also slap on the extremely similar and copyright-free China Export logo
2015-07-15T07:16:09 < PeterM> no such thing as chia export logo, its just a CE logo that chinese dont give a fuck about
2015-07-15T07:16:14 < jpa-> i don't think copyright has anything to do with that
2015-07-15T07:16:33 < jpa-> and the EU laws that rule on CE also apply to crappily drawn versions of that, according to EU
2015-07-15T07:17:42 < dongs> http://www.boatingbusiness.com/__data/assets/image/0004/522499/varieties/carousel.jpg
2015-07-15T07:18:18 < PeterM> >dont give a fuck about
2015-07-15T07:18:25 < jpa-> but generally the sanctions for slapping CE mark while failing EMC tests are just mandate to fix / ban to market until fixed.. if it is really distruptive, manufacturer recall - and all these only if someone bothers to check
2015-07-15T07:19:49 < jpa-> (EU has laws about what it means to put CE mark on a device; whether you call it 'china export' or not doesn't matter, as EU considers it still a CE mark)

2015-07-15T12:40:31 < trepidacious> I don't really like the idea of psoc - when they get a decent open source toolchain for it I'll definitely give it a go
2015-07-15T12:40:46 < trepidacious> But even then you are more than usually tied into one particular manufacturer
2015-07-15T12:49:26 < dongs> thats pretty much the fact with any configurable logic so what are you crying about
2015-07-15T12:49:42 < dongs> you need to understand that chip vendors make stuff for their usual customers, not opensauce whiners
2015-07-15T12:49:51 < dongs> who wouldn't pay for thier software anyway
2015-07-15T12:50:03 < trepidacious> dongs: Do you not use gcc though?
2015-07-15T12:50:13 < dongs> only if i ahve to
2015-07-15T12:50:21 < dongs> would much rather not, and 95% of my projects arent
2015-07-15T12:50:29 < trepidacious> What do you use instead?
2015-07-15T12:50:35 < dongs> armcc
2015-07-15T12:50:43 < dongs> the onyl gcc project i have are actually still in a commercial IDE
2015-07-15T12:50:44 < trepidacious> fair enough
2015-07-15T12:50:47 < dongs> taht just happens to use gcc as backend
2015-07-15T12:50:50 < dongs> crossworks
2015-07-15T12:50:55 < dongs> project=projects
2015-07-15T12:51:09 < dongs> raw gcc/eclipse shit is just so much aids
2015-07-15T12:51:57 < trepidacious> dongs: I'm fine with it, I really don't like commercial IDEs, I've used a few (e.g. for FPGA) and they tend to be a pain in the arse
2015-07-15T12:52:21 < trepidacious> dongs: I'd be happy with an equivalent of armcc for psoc/fpga type stuff - something that is a bit broader than just one manufacturer
2015-07-15T12:53:08 < trepidacious> dongs: I guess in that sense it could just be a language for using psoc stuff that covers a few different choices of manufacturer, VHDL/Verilog is kind of like that I guess
2015-07-15T12:53:21 < Laurenceb> i dont get the point of PSoC
2015-07-15T12:53:28 < Laurenceb> what does it do thats so special
2015-07-15T12:54:15 < _Sync_> nothing
2015-07-15T12:54:21 < Laurenceb> xactly
2015-07-15T12:54:45 < trepidacious> Fair enough, in that case forget about the tools ;)

2015-07-15T15:26:44 < mtbg> or, maybe fortunately, considering the frustration it induces
2015-07-15T15:26:45 < mtbg> :>
2015-07-15T15:27:01 < zyp> haha, ok
2015-07-15T15:27:10 < zyp> what's the issue?
2015-07-15T15:28:08 < mtbg> we are working on UAC2 card on stm32f407, works perfectly ok under linux and snd-usb-audio
2015-07-15T15:28:27 < mtbg> but windows doesn't support UAC2, only UAC1, in generic usb audio drivers
2015-07-15T15:28:37 < zyp> ah, right
2015-07-15T15:28:38 < mtbg> to run UAC2 you have to use third-party drivers
2015-07-15T15:28:58 < zyp> that sounds pretty annoying, yeah
2015-07-15T15:29:20 < mtbg> and there are none free of charge
2015-07-15T15:29:25 < mtbg> let alone open source
2015-07-15T15:29:40 < _Sync_> trolled
2015-07-15T15:29:42 < mtbg> there are some from thesycon which are paid
2015-07-15T15:30:13 < zyp> what's different between 1 and 2?
2015-07-15T15:30:27 < mtbg> we are currently trying to set them up since there is some demo version, and it almost works
2015-07-15T15:31:20 < karlp> dongs: back to work tomorrow, will check then, it was ft230x we were using, the qfn one,
2015-07-15T15:31:21 < mtbg> but windows claims it is unable to "enable" the audio device and because of this doesn't stream audio to it nor displays controls in volume control
2015-07-15T15:32:26 < mtbg> UAC1 was created in 1998, it has dedicated class specific request for controls (SET_CUR, SET_MIN, SET_MAX, SET RES / GET_CUR, GET_MIN, GET_MAX, GET_RES)
2015-07-15T15:33:22 < mtbg> device can have interrupt endpoint for reporting control changes, but the status you can return only indicates the control which causes an event
2015-07-15T15:33:30 < mtbg> not what the event was
2015-07-15T15:34:38 < mtbg> in UAC2 from 2006 they somewhat fixed it to more elegant protocol, you have SET_CUR, SET_RANGE / GET_CUR, GET RANGE
2015-07-15T15:34:57 < mtbg> and interrupt endpoint returns somewhat more precise status
2015-07-15T15:36:00 < _Sync_> easy, just don't support windows
2015-07-15T15:36:09 < mtbg> where you can tell the exact parameter which have changed
2015-07-15T15:36:36 < mtbg> and, AFAIK UAC1 can't work in HS
2015-07-15T15:37:35 < mtbg> there are also some nice changes in the class-specific descriptor infrasturcture, so that you don't have to have fixed sampling rates
2015-07-15T15:37:55 < mtbg> and let the host choose one of the available
2015-07-15T15:38:26 < mtbg> there are variable or fixed clock sources, clock multipliers and clock selectors instead

2015-07-15T15:40:58 < mtbg> linux also has a bug in UAC1 support in current kernel version, but a very minor one
2015-07-15T15:42:00 < mtbg> the driver doesn't mark it's internally cached control value after an interrupt as invalid
2015-07-15T15:42:29 < mtbg> so the userspace gets the change event, but then reads the cached value from the driver
2015-07-15T15:42:40 < _Sync_> well mtbg it is a problem of the user to get the device running
2015-07-15T15:42:54 < _Sync_> well, that sounds like an easy fix
2015-07-15T15:43:09 < mtbg> yep, one line fix, something like ctl->cached = 0;
2015-07-15T15:43:20 < mtbg> and it works when fixed in that way

2015-07-15T17:58:01 < ReadMobl> Why
2015-07-15T17:58:24 < Ecco> Allright, it's a scam. How about we talk about the other million of them? For instance, hasn't any of you been in touch with a rich Nigerian? :-)
2015-07-15T18:00:16 < englishman> eventually the nigerial will take your money and walk away
2015-07-15T18:00:24 < englishman> this scam is public and doesnt appear to be going anywhere
2015-07-15T18:00:40 < englishman> also its not like anyone in here is doing anything stm32 related
2015-07-15T18:00:58 < dongs> hey im doing a new stm32-related shit for work
2015-07-15T18:01:15 < Ecco> The Zano uses an ST mcu?
2015-07-15T18:01:23 < dongs> of course not
2015-07-15T18:01:27 < Ecco> :-D
2015-07-15T18:01:48 < Ecco> Allright, so let me introduce you to this MP3 player a friend of mine bought in Beijing
2015-07-15T18:01:56 < dongs> does it have a stm32?
2015-07-15T18:01:56 < Ecco> Works just fine
2015-07-15T18:02:01 < Ecco> not either :-D
2015-07-15T18:02:05 < dongs> or one of those VS1003 shits
2015-07-15T18:02:08 < englishman> plz stay on topic
2015-07-15T18:02:18 < Ecco> Works just fine… until you plug it off the power brick
2015-07-15T18:02:31 < Ecco> those bastards put a piece of scrap metal where the battery should have been
2015-07-15T18:02:44 < dongs> lies

2015-07-15T18:03:52 < qyx_> should the player work without the power brick?
2015-07-15T18:04:00 < Ecco> it should
2015-07-15T18:04:03 < Ecco> it was an iPod copycat
2015-07-15T18:04:33 < Ecco> the dude selling them told my friend "yeah, right now it won't work because the battery is dischared, but when you get back home and charge it for a while it'll be ok"
2015-07-15T18:04:49 < Ecco> it won't work *unplugged*
2015-07-15T18:05:04 < Ecco> Because he did give him a demo of the thing, plugged in of course
2015-07-15T18:05:24 < dongs> well wat are you waiting for

2015-07-15T18:05:27 < qyx_> is that bad actually?
2015-07-15T18:05:31 < dongs> just plug in a zano PCM-protected battery

2015-07-15T18:06:15 < englishman> but, who would buy an mp3 player in 2015

2015-07-15T18:07:03 < dongs> in the shape of the battery

2015-07-15T19:07:58 < specing> yeah, and nobody lists chemistry almost everywhere I look
2015-07-15T19:08:09 < specing> (meaning probably lifepoo4)
2015-07-15T19:08:53 < PeterM> there are lots of licoo2
2015-07-15T19:09:05 < PeterM> they seem to be far more common than lifepo4
2015-07-15T19:09:17 < specing> and when I calculate energy density from provided mAh and weight ratings I get that they are better than what has been achived in a lab
2015-07-15T19:09:52 < specing> like... 350Wh/kg
2015-07-15T19:10:14 < qyx_> wat
2015-07-15T19:10:17 < qyx_> 350Wh/kg?

2015-07-15T19:10:21 < qyx_> which one?
2015-07-15T19:10:34 < PeterM> if they dont have one, be careful
2015-07-15T19:10:49 < qyx_> there are 18650 cells on ebay rated at 5000mAh
2015-07-15T19:11:14 < qyx_> probably they hardly reach 2000
2015-07-15T19:11:19 < specing> yeah...
2015-07-15T19:11:36 < specing> I saw a review put an ultrafire 3500 mAh cell at 850 mAh

2015-07-15T19:28:37 < specing> pouch as in li-po (flatpacks)?

2015-07-15T19:29:05 < PeterM> but not as common
2015-07-15T19:31:36 < specing> well the end problem is where to get them
2015-07-15T19:31:46 < specing> judging by their price, they should indeed be NMC

2015-07-15T20:01:42 < jpa-> more useful in what way?
2015-07-15T20:03:24 < Steffanx> android in virtualbox? :P
2015-07-15T20:05:01 < jpa-> google gives plenty of info on how to use them from pc, so i guess "more useful" means something more than just getting the image?
2015-07-15T20:05:52 < ReadError> android battery life is already pretty horrible

2015-07-16T10:19:14 < ReadError> but china fabs have worse specs so would have to change all my vias etc
2015-07-16T10:19:16 < PeterM> i assume not through OSHpark though because of pricing?
2015-07-16T10:19:24 < ReadError> or use china fab specs to begin with
2015-07-16T10:19:33 < ReadError> no ive used them for the 60

2015-07-16T10:20:59 < PeterM> ok
2015-07-16T10:21:41 < PeterM> i dont do many board wit hthem - only small quick test boards to break out a chip

2015-07-16T10:24:53 < PeterM> like i was talkin about some WLCSP buck-boost converters a few months ago - i got a bunch of boards done for them from oshpark, i got 6 made, only 1 was useable because of over etch

2015-07-16T10:33:09 < ReadError> yea but I rarely need 200 boards ;)
2015-07-16T10:33:18 < ReadError> china guy told me about some panelization software he uses
2015-07-16T10:33:48 < dongs> "rarely"
2015-07-16T10:33:58 < dongs> 200 is like your minimum order

2015-07-16T10:47:24 < ReadError> panelization isnt the hard part
2015-07-16T10:47:34 < dongs> er, i just let the pros panelize

2015-07-16T10:47:42 < dongs> i just mspaint how i want it

2015-07-16T10:47:50 < dongs> and the guy makes a beautiful array
2015-07-16T10:48:05 < dongs> too many vcuts = expensive
2015-07-16T10:48:14 < dongs> having proper mix of mousebites/routing is laso important
2015-07-16T10:48:25 < dongs> just newb arraying 500 boards into a single sheet is guarantaeed to end up with fail
2015-07-16T10:49:13 < PeterM> ofcourse, but itrs not hard to panelize small array liek 5x5 you just vscore 1 direction, route other direction
2015-07-16T10:49:33 < PeterM> leave carriers unrouted
2015-07-16T10:50:10 < dongs> the produde uses cam350

2015-07-16T10:50:19 < dongs> to see how its done
2015-07-16T10:50:29 < dongs> probably not something i need to know anyway
2015-07-16T10:51:26 < PeterM> i just do it so i can send shit off to the cheapest bidder and not worry they will fuck up my boards without me being able to yell at them

2015-07-16T13:24:07 < dongs> Currently, Lily does not have any obstacle avoidance capabilities. We have found that most outdoor activities do not need obstacle avoidance because Lily can follow the user's path. But again, there are no guarantees that Lily will not hit anything while it is following you. If Lily is about to hit an object you can press the middle button on the tracking device and Lily will stop, hold its position, and continue to film you.

2015-07-16T18:17:06 < ReadError> just to make working headers w/o a ton of work, if it can do
2015-07-16T18:17:45 < jpa-> headers?
2015-07-16T18:17:58 < jpa-> what headers do you need to make?
2015-07-16T18:19:21 < ReadError> all the config files
2015-07-16T18:19:33 < ReadError> I heard there is some mechanism of generating them
2015-07-16T18:19:39 < ReadError> like the MCU specific stuff
2015-07-16T18:19:54 < jpa-> mcuconf/chconf/halconf? just copy from an example for the processor you want and modify as needed
2015-07-16T18:20:01 < jpa-> it's not like there is much to generate about it
2015-07-16T18:20:08 < ReadError> well this is that f042 20pin deal
2015-07-16T18:20:13 < ReadError> so yea needs some heavy mods
2015-07-16T18:20:37 < jpa-> hum, like what mods?
2015-07-16T18:20:43 < ReadError> i sorta figured out the hal vs hal_lld stuff
2015-07-16T18:20:55 < ReadError> but it seems like there are a lot of duplicate files
2015-07-16T18:21:05 < ReadError> like stuff in \hal then \rt
2015-07-16T18:21:16 < ReadError> like a lot of overlap filename wise, then port
2015-07-16T18:21:52 < jpa-> you know only to include the files for your specific processor, right?
2015-07-16T18:21:57 < ReadError> right
2015-07-16T18:22:09 < jpa-> a bit annoying to do in some IDE instead of using the makefiles
2015-07-16T18:22:23 < ReadError> yea, I can see how make files on this would be a ton easier
2015-07-16T18:22:29 < ReadError> since you just inclue the .mk's
2015-07-16T18:23:40 < englishman> i get the makefile stuff
2015-07-16T18:23:40 < ReadError> maybe has something to do w/ being 3.0
2015-07-16T18:23:49 < englishman> but i just dont like my OS to be my IDE
2015-07-16T18:23:52 < ReadError> seems the directory structure has changed up
2015-07-16T18:23:57 < ReadError> openOCD scurrs me
2015-07-16T18:24:06 < ReadError> i can work the keil one fine
2015-07-16T18:24:24 < jpa-> perhaps it is possible to compile chibios as .a so you can just include it up
2015-07-16T18:25:55 < ReadError> oh i just realized what rvct meant
2015-07-16T18:26:11 < ReadError> thats another fucky thing, all the subdirs for different compilers
2015-07-16T18:26:23 < jpa-> what's fucky about that?
2015-07-16T18:26:34 < jpa-> seems the sanest way to do portability for that lowlevel crap
2015-07-16T18:27:21 < ReadError> jpa-, in your opinion is it best to stay w/ 2.6.8 or is 3.0 stable enough to start with ?
2015-07-16T18:27:28 < jpa-> 3.0 works fine for me
2015-07-16T18:27:53 < jpa-> worked fine already in betas, so yeah, i'd guess the stable is quite stable
2015-07-16T18:28:15 < ReadError> I have the 407disco project compiling so i think it might be easiest to change that up for the f0
2015-07-16T18:28:28 < ReadError> also ya I remembered what I was going to ask
2015-07-16T18:28:37 < ReadError> the project came w/ 2 linker files, vectors.s
2015-07-16T18:28:59 < ReadError> and another one... which I cant remember the name, that doesnt exist anymore I guess
2015-07-16T18:29:48 < jpa-> vectors.s sounds like assembler, not linker?
2015-07-16T18:30:00 < ReadError> ahhh startup file I mean
2015-07-16T18:30:03 < ReadError> im fried
2015-07-16T18:30:27 < jpa-> how about starting with one of the few chibios demos that have keil project files?
2015-07-16T18:30:57 < jpa-> they might be more up to date with the 3.0 files

2015-07-16T23:48:51 < znfgnu> Hello everyone!
2015-07-16T23:49:34 < znfgnu> I've just bought stm32f4 board and I'm trying to run ssd1306 lcd under it
2015-07-16T23:50:31 < znfgnu> Where should I start? I'm newbie with ARM, I've run this lcd under arduino already
2015-07-16T23:51:44 < znfgnu> Whole yesterday I was playing with libraries (I modified LED blink project) but everything I got was only bunch of errors I wasn't able to find solution for
2015-07-16T23:59:28 < znfgnu> arm
--- Day changed Fri Jul 17 2015
2015-07-17T00:02:31 < Taxman> well, the start of a new arch is always hard
2015-07-17T00:03:39 < znfgnu> could You give me some useful information for the beginning?
2015-07-17T00:03:53 < Taxman> what is with the blink project?
2015-07-17T00:04:16 < Taxman> did you successful compile it and execute it?
2015-07-17T00:04:36 < znfgnu> simple blinking with LED diode. Yes, it's blinking already ;)
2015-07-17T00:05:20 < Taxman> with the compiled by you?
2015-07-17T00:05:22 < znfgnu> can I post hyperlinks here?
2015-07-17T00:05:58 < znfgnu> Yes, by me. I cloned project frm github, compiled successfully
2015-07-17T00:06:12 < znfgnu> and after that I started playing with it
2015-07-17T00:06:52 < znfgnu> I'm not new to programming, just new to ARMs ;)
2015-07-17T00:07:33 < Taxman> well.. why not going on from here? when it does not compile anymore you know what you did...
2015-07-17T00:09:26 < znfgnu> I wanted to use example code from library
2015-07-17T00:09:38 < Taxman> what library?
2015-07-17T00:09:47 < znfgnu> can I post hyperlinks here?
2015-07-17T00:10:04 < Taxman> i think so
2015-07-17T00:10:12 < znfgnu> http://stm32f4-discovery.com/2015/05/library-61-ssd1306-oled-i2c-lcd-for-stm32f4xx/ - this one
2015-07-17T00:10:57 < znfgnu> I cloned this repo: https://github.com/rowol/stm32_discovery_arm_gcc
2015-07-17T00:11:11 < znfgnu> And modified sources in "blinky" project
2015-07-17T00:13:34 < znfgnu> I also downloaded every library needed for example code from this ssd1306 lib
2015-07-17T00:13:47 < znfgnu> and put to "blinky" directory
2015-07-17T00:14:13 < znfgnu> (and modified Makefile to compile all .c files inside this dir)
2015-07-17T00:15:54 < znfgnu> There's not much information over the internet about programming arm under linux (or I just can't find it)
2015-07-17T00:19:10 < Taxman> but about programming arm with gcc/eclipse/... maybe you should search for this
2015-07-17T00:20:43 < znfgnu> how did You start, by the way? ;)
2015-07-17T00:20:53 < Taxman> by the very hard way
2015-07-17T00:20:59 < Taxman> no external libs, just cmsis
2015-07-17T00:21:10 < Taxman> compiled gcc from scratch
2015-07-17T00:21:24 < Taxman> and did my own drivers, at register level
2015-07-17T00:21:59 < znfgnu> whoa, respect, really.
2015-07-17T00:22:23 < znfgnu> what is cmsis for?
2015-07-17T00:22:59 < Taxman> just a big header file, register definitions and so on
2015-07-17T00:28:06 < znfgnu> I don't even know what to ask You for. I don't want You to do the whole work for me, but I don't even know what to read after successfully compiled and flashed blink project
2015-07-17T00:29:12 < Taxman> what do you want? a gui on a tft?
2015-07-17T00:29:53 < znfgnu> I made a prototype of "smartwatch" on arduino, it's working fine
2015-07-17T00:30:34 < Taxman> well then just rewrite gpio stuff and have fun?
2015-07-17T00:30:48 < znfgnu> I want to port this to ARM platform, because in the far future I'd like to run external plugins on it
2015-07-17T00:30:53 < Taxman> how is the ssd connected to the stm32?
2015-07-17T00:31:54 < znfgnu> I followed instrucion from this ssd1306 lib site
2015-07-17T00:32:51 < Taxman> i have never worked with the ssd
2015-07-17T00:33:05 < znfgnu> scl -> PA8, sda -> PC9
2015-07-17T00:33:27 < znfgnu> but my problem is that I can't even compile this project
2015-07-17T00:33:44 < Taxman> ok, i2c
2015-07-17T00:34:16 < Taxman> go through the errors and fix them
2015-07-17T00:36:01 < znfgnu> yes, I but yesterday I ended up with "undefined reference to `__end__'"
2015-07-17T00:37:29 < Taxman> never seen this
2015-07-17T00:37:42 < Taxman> maybe others here can tell something
2015-07-17T00:37:54 < Taxman> if they are not enjoying the sweet night
2015-07-17T00:39:22 < znfgnu> would You like to look at sources and makefile? Maybe it's some king of simple thing
2015-07-17T00:40:05 < znfgnu> Usually I try to go through problems by myself but last time I don't have much time for this project
2015-07-17T00:40:07 < Taxman> not this night. i have already dunken too much ;)
2015-07-17T00:41:10 < znfgnu> unfortunately :P

2015-07-17T01:33:42 < scummos^> hmm. I use my controller with USB as a virtual serial device to just transfer some bulk data to a computer running linux (the device is used through some /dev/ttyACMn API). but sometimes, chunks of data go missing
2015-07-17T01:33:46 < scummos^> I wonder how this can happen?
2015-07-17T01:34:05 < scummos^> the microcontroller waits for the endpoint to finish the transmission before transmitting the next packet
2015-07-17T01:34:17 < scummos^> maybe the physical buffer on the host system overflows?
2015-07-17T01:34:36 < scummos^> I'm really kind of clueless where this could go wrong
2015-07-17T01:36:29 -!- znfgnu [~znfgnu@87-207-53-100.dynamic.chello.pl] has joined ##stm32
2015-07-17T01:37:59 < scummos^> inserting a short delay after each packet on the microcontroller seems to fix it
2015-07-17T01:38:03 < scummos^> but I don't want to do that
2015-07-17T01:38:10 < scummos^> it feels bad and I need the bandwidth
2015-07-17T01:40:07 < effractur> running over the transmit buffers?
2015-07-17T01:40:33 < scummos^> but I wait for the transmission to finish before sending the next packet ...
2015-07-17T01:40:39 < effractur> mm
2015-07-17T01:41:12 < scummos^> I checked as good as I could that this actually works as well, using a debugger etc.
2015-07-17T01:41:30 < emeb> you sure that the USB xmit is done? Sometimes ST periphs will say "done" before they're really done and there are other bits you have to watch to be sure.
2015-07-17T01:42:08 < emeb> like on SPI the TE bit goes valid before all the data is out of the chip so you have to watch BUSY to be sure...
2015-07-17T01:42:20 < scummos^> that was also my suspicion, yes ...
2015-07-17T01:42:30 < scummos^> the part is a LPC4333 (cortex m4)
2015-07-17T01:43:13 < scummos^> but I tried a lot of methods for waiting
2015-07-17T01:43:34 < scummos^> the USB subsystem is also huge and hugely complicated :(
2015-07-17T01:44:11 < emeb> ya - no matter whose MCU you use, USB is deep & frustrating.
2015-07-17T01:44:37 < emeb> can you try on another OS?
2015-07-17T01:44:51 < emeb> make sure that it's not the linux USB stack that's losing the data?
2015-07-17T01:45:13 < scummos^> maybe I should do that, yeah
2015-07-17T01:45:29 < scummos^> although it's quite some effort and it does not seem like the most likely cause ...
2015-07-17T01:45:30 < emeb> (if dongs were awake he'd tell you that it's lunix that's causing your problems :) )
2015-07-17T01:45:38 < scummos^> I mean, the linux usb stack is quite well established
2015-07-17T01:45:42 < emeb> ya
2015-07-17T01:46:15 < emeb> only other thing would be to use a USB protocol analyzer. I doubt you have that...
2015-07-17T01:46:46 < scummos^> nope ;)
2015-07-17T01:46:53 < scummos^> but well, there is USB capture software
2015-07-17T01:46:54 < effractur> you can capture usb with wireshark
2015-07-17T01:47:31 < scummos^> but in principle (just to make sure), when the receive buffer on the host is full, I would expect the endpoint to stall, right?
2015-07-17T01:47:51 < scummos^> and not tell me "ready" and when I put more data in there would be an overflow
2015-07-17T01:50:57 < scummos^> maybe I'll indeed try wireshark
2015-07-17T01:51:08 < scummos^> maybe it tells me if the problem is on the host or on the device

2015-07-17T04:33:03 < ReadMobl> Keil MDK-ARM for STM32F0 and STM32L0 provides software developers working with STM32 devices based on the ARM Cortex-M0 and ARM Cortex-M0+ cores with a free-to-use professional tool suite. Keil MDK is the most comprehensive software development system for ARM processor-based microcontroller applications. Keil MDK includes the ARM C/C++ Compiler, the
2015-07-17T04:33:03 < ReadMobl> CMSIS-RTOS RTX Kernel, and the µVision IDE/Debugger. The STM32 peripherals can be configured using STM32 CubeMX and the resulting project exported to MDK.
2015-07-17T04:33:06 < ReadMobl> interesting
2015-07-17T04:33:22 < ReadMobl> btw emeb, got a few boards built, flashed one seems to work great
2015-07-17T04:34:55 < emeb> ReadMobl: cool!
2015-07-17T04:36:03 < emeb> crystal-less USB is pretty neat, and I like that you can flash firmware into it with the bootloader via USB DFU.
2015-07-17T04:36:59 < ReadMobl> now back to trying to get the chibios project setup in keil ;(
2015-07-17T04:40:43 < dongs> lol.
2015-07-17T04:40:55 < dongs> ReadMobl: --gnu --c99 should cover ~99% of chibishit fails
2015-07-17T04:41:11 < ReadMobl> nah its setting up all 20 include directories
2015-07-17T04:41:12 < dongs> butits too many files so its probly just aw aste of time

2015-07-17T04:45:42 < zyp> dongs, I guess it still doesn't enable gcc-style inline asm?
2015-07-17T04:46:14 < zyp> which is a shame
2015-07-17T04:51:22 < dongs> inline asm is for faggots anyway tho
2015-07-17T04:51:28 < dongs> there's like zero reason for it
2015-07-17T04:51:52 < dongs> only people who use gcc like to use inline asm cuz they think they're smarter than teh compiler
2015-07-17T04:54:00 < zyp> or want to write context switch routines and other lowlevel shit
2015-07-17T04:54:14 < zyp> rather than going all asm
2015-07-17T04:54:42 < zyp> the neat part about gcc inline asm is how it integrates with the register allocator
2015-07-17T04:55:30 < zyp> rather than hardcoding registers, you tell the compiler what sort of registers you need with what values, and then the register allocator does it's thing and assigns you an appropriate register
2015-07-17T04:58:21 < ReadMobl> also they took all the keil projects out of 3.0 for some reason
2015-07-17T04:59:44 < dongs> zyp, probaly cuz it s integration of gcc+gas shit
2015-07-17T04:59:52 < dongs> going to be impossible to emulate with a real compiler
2015-07-17T05:00:32 < zyp> no, this happens all before the assembly stage
2015-07-17T05:00:46 < zyp> any compiler does register allocation at some point
2015-07-17T05:12:38 < emeb> Only time I've used inline asm was when I wanted to use the M4 saturation instruction before gcc supported it.
2015-07-17T05:13:19 < emeb> now it'll infer that from your C code, so no need.
2015-07-17T05:16:26 < dongs> oops i missed altidong .13 release
2015-07-17T05:16:34 < dongs> they fixed the annoying shit where you couldnt edit via size during routing sometime
2015-07-17T05:16:46 < dongs> that they fucked up after introducing via templates a couple versions ago

2015-07-17T18:11:42 < Ecco> Guys, I'm doing a back-of-the-enveloppe estimate
2015-07-17T18:11:50 < Ecco> And I think I'm overlooking something
2015-07-17T18:12:23 < Ecco> I'm considering a Cortex M0+ from Atmel paired with a graphic black&white, non-backlight LCD
2015-07-17T18:12:57 < Ecco> If I got things right, the SAML21@10 MHz should eat 0.5 mA @ 3V, and the LCD controller should take 1.2 mA @ 3V.
2015-07-17T18:13:30 < Ecco> That makes a grand total of 1.5 mA @ 3V. Now Energizer says their CR2032 button batteries have a capacity of 240 mAh at 3V
2015-07-17T18:13:58 < Ecco> Would that mean that, *in theory* I could power the LCD + CortexM0+ for like 160 Hours off of a single cell ????
2015-07-17T18:14:06 < Ecco> That seems, well… weird
2015-07-17T18:17:51 < rkreis_> Ecco, not super weird
2015-07-17T18:17:53 < englishman> less than a week?
2015-07-17T18:18:12 < rkreis_> keep in mind the voltage of your CR2032 drops quite a bit, will that stil work with 2V?
2015-07-17T18:18:33 < Ecco> Well, that's a week of full, *continuous* use
2015-07-17T18:18:39 < Laurenceb> so
2015-07-17T18:18:44 < Ecco> I know that's a theoretical calculation
2015-07-17T18:18:46 < Laurenceb> digital watches run for years]
2015-07-17T18:18:49 < Ecco> Indeed :)
2015-07-17T18:18:59 < Ecco> But on the other hand my smartphone can barely make a few hours
2015-07-17T18:19:05 < Ecco> I know those aren't the same devices
2015-07-17T18:19:09 < Laurenceb> i have a calculator from 1984
2015-07-17T18:19:20 < englishman> you could shut off lcd controller when not updating maybe
2015-07-17T18:19:21 < Laurenceb> with original button cell
2015-07-17T18:19:23 < Laurenceb> run fine
2015-07-17T18:19:25 < rkreis_> remember when smartphones had b/w displays? weren't those always-on, too?
2015-07-17T18:19:25 < Ecco> but Cortex M0 + graphic LCD is at least as close to a digital watch than to an iPhone
2015-07-17T18:19:35 < englishman> i dont know any digital watch with ARM
2015-07-17T18:19:42 < Ecco> rkreis_: good point indeed
2015-07-17T18:19:48 < rkreis_> backlights really suck (electricity out of batteries), and so do the very powerful processors they push into smartphones now
2015-07-17T18:19:57 < Ecco> Ok !
2015-07-17T18:20:12 < gxti> meanwhile my shitty digital calipers chew through a button cell in 3 months with very little use
2015-07-17T18:20:14 < englishman> the lcd probably has a low power mode that only uses that kind of power when active and updating the screen
2015-07-17T18:20:23 < rkreis_> cortex m0 are definitely suited for powering things for ages from a CR2032
2015-07-17T18:20:24 < gxti> i measured the current draw, it's the same whether it's on or off
2015-07-17T18:20:30 < englishman> heh
2015-07-17T18:20:51 < Ecco> I haven't looked at Cortex M0 more in depth
2015-07-17T18:20:56 < englishman> Ecco: theres stm32l1 discovery that has onboard current sensor
2015-07-17T18:20:56 < Ecco> How would they compare to a M4?
2015-07-17T18:20:59 < englishman> thats good to like nA
2015-07-17T18:21:13 < englishman> for dicking with low power cell battery powered shit
2015-07-17T18:21:17 < englishman> and it works to 1.8v
2015-07-17T18:21:18 < Ecco> ok :)
2015-07-17T18:21:21 < englishman> or 1.65 or something
2015-07-17T18:21:28 < Ecco> I need 3V for the LCD anyway
2015-07-17T18:21:32 < rkreis_> some missing features, some design differences that give less performance but also minimize power usage
2015-07-17T18:22:06 < Ecco> ok
2015-07-17T18:22:15 < Ecco> But still targetable from clang/gcc for example?
2015-07-17T18:22:19 < rkreis_> absolutely
2015-07-17T18:22:22 < Ecco> nice
2015-07-17T18:22:35 < Ecco> I think I'll need quite  alot of flash though
2015-07-17T18:22:42 < Ecco> I haven't looked at ST yet
2015-07-17T18:22:52 < Ecco> but the largest M0+ Atmel offers comes with 256 Kb
2015-07-17T18:23:00 < Ecco> and 32 Kb of RAM
2015-07-17T18:23:13 < rkreis_> if that's still too little, add an SD card (which will probably be the biggest power issue at that point)
2015-07-17T18:23:36 < Ecco> Good suggestion, but what I like on the M4 that I use now is that the flash is 0 wait state
2015-07-17T18:23:46 < Ecco> I don't know if you can execute code off of the SD card for example
2015-07-17T18:24:14 < rkreis_> it's not trivial, at least
2015-07-17T18:24:18 < Ecco> indeed
2015-07-17T18:24:33 < Ecco> I guess you have to copy to RAM and jump?
2015-07-17T18:24:44 < rkreis_> on the other hand, 256K is a lot for just code

2015-07-17T18:25:32 < Ecco> Depends on what you want to do I guess
2015-07-17T18:25:49 < Ecco> Just a bitmap font will take a few tens of kb already
2015-07-17T18:26:28 < rkreis_> to give some perspective, this project is around 1k lines of code and uses up 6K, so by that logic 256K means 40k lines of code (very rough estimate!)
2015-07-17T18:27:02 < karlp> Ecco: l0, l1 and l4...
2015-07-17T18:27:35 < Ecco> rkreis_: which project?
2015-07-17T18:27:50 < rkreis_> some wireless sensor network toying
2015-07-17T18:28:01 < Ecco> oh sorry, I just re-read and understood what you meant :)
2015-07-17T18:29:31 < Ecco> But anyway, so the estimate of 100+ hours off of a single CR2032 doesn't seem far-fetched
2015-07-17T18:29:34 < Ecco> Interesting!

2015-07-17T19:16:26 < Ecco> PointerToNull: I'm using STM32F429IDisco on OS X just fine
2015-07-17T19:16:28 < Ecco> You'll want :
2015-07-17T19:16:37 < Ecco> -> OpenOCD to send your program and debug it
2015-07-17T19:16:47 < Ecco> -> GCC (or clang) to build binaries from C code
2015-07-17T19:18:14 < PointerToNull> Ecco really? You use just this two tools and you are able to compile, upload and debug your firmware?
2015-07-17T19:19:02 < DanteA> Not only gcc
2015-07-17T19:19:19 < DanteA> You need full toolchain
2015-07-17T19:20:00 < DanteA> Arm none eabi
2015-07-17T19:20:03 < PointerToNull> Ecco, do you have a guide that I can follow to do it? Because I'm still quite new to the paramether I have to send to the compiler to compile for my architecture
2015-07-17T19:20:25 < trepidacious> I'd recommend the ARM GCC toolchain: https://launchpad.net/gcc-arm-embedded
2015-07-17T19:21:04 < trepidacious> An alternative to OpenOCD that might be slightly easier to set up is texane stlink: https://github.com/texane/stlink
2015-07-17T19:21:06 < PointerToNull> DanteA, right, so I need the Arm none eabi on my mac, the compiler (Clang or GCC) and this OpenOCD and thats it?
2015-07-17T19:21:09 < trepidacious> However OpenOCD may well work better
2015-07-17T19:21:39 < DanteA> Toolchain included compiler
2015-07-17T19:22:43 < PointerToNull> Ok great!
2015-07-17T19:22:55 < karlp> in cmake sources, are you meant to list .h files yourself? or just list all the .c files and cmake does the right thing? anyone use cmake much?
2015-07-17T19:25:42 < trepidacious> Is cmake just make?
2015-07-17T19:26:39 < trepidacious> Ah looks like not, in that case I've only used Make. If you want some code to compile, maybe try ChibiOS, they have make files that definitely work on arm gcc
2015-07-17T19:27:02 < trepidacious> Even if you don't flash or use them for anything else you can check your toolchain works and look at how they are set up
2015-07-17T19:32:50 < karlp> thanks.... I guess :)
2015-07-17T19:32:56 < karlp> I've got plenty of makefiles that work just fine :)
2015-07-17T19:34:18 < trepidacious> karlp: That was for PointerToNull :)
2015-07-17T19:34:41 < trepidacious> ah I'm so confused, that was a composite answer to two different questions :(
2015-07-17T19:34:51 < trepidacious> Ignore me ;)
2015-07-17T19:34:52 < karlp> PointerToNull: don't use texane/stlink, you're just setting up more pain down the road
2015-07-17T19:35:17 < karlp> openocd 0.9 is plenty fine, 0.8 is plenty fine too
2015-07-17T19:35:17 < trepidacious> karlp: What problems have you had with it?
2015-07-17T19:35:40 < karlp> trepidacious: it's ok if you get a version that works and don't touch it :)
2015-07-17T19:35:58 < karlp> but it has traditionally been _very_ poor at keeping things working after patches for new targets
2015-07-17T19:36:21 < karlp> it used to provide substantially more functionality than openocd, and was a good option.
2015-07-17T19:36:32 < karlp> I would no longer recommend it for anyone new.
2015-07-17T19:38:17 < karlp> the answer by the way is no, you don't need to list the headers in your cmake sources, it works that for you just fine.
2015-07-17T19:39:30 < trepidacious> karlp: I should really get OpenOCD set up, I've used texane for years now, I guess I'm just used to it
2015-07-17T19:40:54 < karlp> it's much much freer approach to merges means you can get some unusual and neat features that openocd doesn't have, but you'll get less surprises with openocd

2015-07-17T19:42:09 < karlp> things like rkreis_ 's patch https://github.com/texane/stlink/commit/8c26581f5937a9f6603d3fbcf056f8aedeed3101 should never have landed in the first place for instance.
2015-07-17T19:43:56 < karlp> (I still think openocd is kinda gross, it's just consistent gross)
2015-07-17T19:45:27 < PaulFertser> I wonder what texane features does openocd lack?
2015-07-17T19:45:43 < karlp> low voltage 8 bit programming for f4 looks like one of the newest ones :)
2015-07-17T19:45:51 < karlp> it has a "friendly" gui
2015-07-17T19:46:13 < karlp> PaulFertser: it sometimes lands new targets faster, but that's not as common anymore
2015-07-17T19:46:32 < PaulFertser> 8 bit programming? STM8?
2015-07-17T19:46:32 < karlp> it's command line interface is _substantially_ easier to grasp for new players though
2015-07-17T19:46:43 -!- jon1012 [~jon@foresight/developer/jon1012] has quit [Ping timeout: 246 seconds]
2015-07-17T19:46:44 < karlp> no, low voltage programming the flash for f4 via 8bit writes
2015-07-17T19:47:01 < emeb> I'd argue that's mainly because it's not nearly as deep as openocd.
2015-07-17T19:47:16 < karlp> emeb: sure, absoltely
2015-07-17T19:47:40 < karlp> but openocd's infinte flexibility via throwing more tcl at it makes it rather insane for new players.
2015-07-17T19:47:48 < karlp> I don't see any easy way around it though
2015-07-17T19:48:11 < karlp> texane/stlink gets to completely avoid the whole "what sort of debug hardware do you have" question
2015-07-17T19:48:21 < emeb> I'm pretty happy with OOCD 0.9.0 - especially how the flashing process has been simplified so you can do it all from the command line with no setup files.
2015-07-17T19:48:37 < karlp> yeah, 0.9 is pretty nice.
2015-07-17T19:51:16 < emeb> I guess the biggest problem I've run into with current ARM development is that there are so many sites out there telling you "the right way to do it" that really don't. They have a solution that "worked for me" on a particular host, with a particular toolchain and particular target. Often with a lot of cargo-cult and incorrect assumptions that just didn't happen to hurt them.
2015-07-17T19:51:38 < karlp> tell me about it!
2015-07-17T19:51:52 < emeb> Some n00b comes along and none of the assumptions line up for him and it's a ball of fail.
2015-07-17T19:51:57 < karlp> so many out there form 2-3 years ago with old code sourcery toolchains and weird hacks for this and that.
2015-07-17T19:52:03 < Rickta59> doesn't help that stuff is constantly changing
2015-07-17T19:52:32 < karlp> oh, emeb, you were saying you were letting gcc do the saturation maths for you now, how was that being done?  does it recognise some checking for overflow code patterns? or are there special markers for it?
2015-07-17T19:52:56 < Rickta59> and no one goes back and marks their old posts with something like this .. this post is crap now
2015-07-17T19:52:58 < karlp> Rickta59: it's stabilized a lot though, now that the launchpad gcc toolchain is around
2015-07-17T19:53:26 < emeb> karlp: gcc recognizes a particular coding pattern as saturation and infers the saturation instruction.
2015-07-17T19:53:30 < Rickta59> yeah once linaro started shipping binaries it simplified things for most people
2015-07-17T19:54:25 < emeb> karlp: there was a patch a year or two back that had some detail on how it works. Don't have a linky at this point tho.
2015-07-17T19:54:45 < Rickta59> i think BMP makes it dead simple to flash and debug stm32 arm chips
2015-07-17T19:55:04 < Rickta59> no host code other than arm-none-eabi-gdb

2015-07-17T19:58:57 < emeb> Yeah BMP is nice.
2015-07-17T19:59:21 < emeb> I've got several of them laying around. Don't use 'em much lately tho.
2015-07-17T19:59:47 < zyp> I use mine a lot
2015-07-17T20:00:48 < trepidacious> karlp: I don't think I need any fancy features - just stlink v2 SWD flashing and simple gdb stuff
2015-07-17T20:01:09 < trepidacious> karlp: I have to say the setup for OpenOCD put me off a little, but I think I did manage to do both those things
2015-07-17T20:01:33 < emeb> zyp: It's been a long time since I updated the firmware on my BMPs - I imagine things have improved some.
2015-07-17T20:01:33 < Rickta59> are you using a custom board? trepidacious
2015-07-17T20:01:56 < zyp> emeb, mostly chip support
2015-07-17T20:01:57 < Rickta59> most of the st boards have an entry you just use
2015-07-17T20:02:16 < zyp> and a few bugfixes I guess
2015-07-17T20:02:19 < emeb> zyp: did your fix for MacOS 10.6.8 composite devices get put in?
2015-07-17T20:02:36 < emeb> that was the main thing I was worried about losing.
2015-07-17T20:02:58 < zyp> the IAD stuff?
2015-07-17T20:03:04 < zyp> hmm, I forgot how that went again
2015-07-17T20:03:20 < zyp> weren't that 10.5 that had issues actually?
2015-07-17T20:04:05 < emeb> there were some issues with the USB descriptors that kept 10.6.8 from enumerating the two ACM devices.
2015-07-17T20:04:29 < emeb> you gave me a patch that got it working.
2015-07-17T20:04:36 < zyp> oh, right, I'm on 10.8
2015-07-17T20:04:59  * emeb 's Mac is ancient and can't upgrade to 10.8
2015-07-17T20:06:14 < zyp> shouldn't be too much work to reproduce the patch for a newer firmware anyway, IIRC you just have to comment out the IAD descriptors from the config, and change the device class from IAD to interface-selected
2015-07-17T20:08:08 < trepidacious> Rickta59: Yup I've used a few
2015-07-17T20:08:32 < trepidacious> Rickta59: But they shouldn't have any important differences to a dev board with the same MCU I guess
2015-07-17T20:09:14 < trepidacious> I don't really get why OpenOCD doesn't just detect the MCU like texane though - it should be able to find out everything it needs?
2015-07-17T20:09:29 < karlp> mrphf getting cmake to get the git describe output into a templated header file seems really gross.
2015-07-17T20:09:43 < karlp> trepidacious: it could and probably should if you tell it "it's an stm32 of some sort"
2015-07-17T20:09:52 < karlp> but oocd supports _wayyyy_ more than just stm32
2015-07-17T20:10:13 < karlp> so currently you have to tell it which stm32 family
2015-07-17T20:13:57 < trepidacious> karlp: Ah that's fair enough

2015-07-17T20:41:36 < Ecco> Anyway, I do also recommend the toolchain from launchpad.net
2015-07-17T20:41:57 < Ecco> You only need openocd (just "brew install openocd")
2015-07-17T20:42:22 < Ecco> Now it's pretty much just a matter of 1/ Building a binary uing the launchpad.net toolchain
2015-07-17T20:42:34 < Ecco> 2/ Sending it over to the board w/ GDB and then stepping through it
2015-07-17T20:42:45 < Ecco> When you run OpenOCD it acts as a GDB server
2015-07-17T20:43:13 < Ecco> so you run openocd in the background and your command-line gdb will connect to openocd for the binary transfer and the actual debugging

2015-07-17T20:44:27 < Ecco> with the battery being user-replaçable

2015-07-18T12:32:18 < ReadError> whats odd is, with it commented out it runs fine, I can see it trying to enumerate my usb, if I uncomment it, it still tries to enumerate but then hits an unhandled exception ;x
2015-07-18T12:32:27 < ReadError> so im kind of baffled

2015-07-18T12:35:35 < jpa-> are you sure you can actually remap usb?
2015-07-18T12:36:17 < jpa-> isn't usb always on PA11/12 and then just other functions can be remapped to PA9/10?
2015-07-18T12:36:17 < ReadError> yea, by default its on PA11/12, note says "4. Pin pair PA11/12 can be remapped instead of pin pair PA9/10 using SYSCFG_CFGR1 register."
2015-07-18T12:37:35 < ReadError> hm i just confused myself, PA11/12 additional function is USB_DM/DP
2015-07-18T12:38:03 < ReadError> but a ctrl+f on the pdf only finds it listed on those 2 pins

2015-07-18T17:59:41 < dongs> 64bit math (some shifts/divides)
2015-07-18T17:59:42 < dongs> or float
2015-07-18T18:00:02 < dongs> not so much faster but maybe take up less code space
2015-07-18T18:00:20 < zyp> what sort of math?
2015-07-18T18:00:35 < zyp> oh, M3
2015-07-18T18:00:47 < dongs> <<16 into 64bits and a couple divides by < 255 numbersr
2015-07-18T18:01:27 < zyp> my bet is that 64bit fixedpoint is faster than softfloat
2015-07-18T18:02:02 < zyp> literal shifts are free due to the inline shifter
2015-07-18T18:02:23 < zyp> whereas I guess softfloat does a bunch of operand shifts
2015-07-18T18:02:55 < zyp> but you might need more registers to keep temporaries for 64bit
2015-07-18T18:03:02 < zyp> so more register pressure
2015-07-18T18:03:59 < zyp> of course, this is completely guesswork, so if you benchmark both, let me know how it works out
2015-07-18T18:04:22 < zyp> on M4F, I'd expect float to be faster

2015-07-18T18:29:54 < zyp> I'd expect it to be 32
2015-07-18T18:30:09 < zyp> you want a «long long»
2015-07-18T18:30:22 < dongs> yeah, keil printf is bitching
2015-07-18T18:30:32 < zyp> but you might as well be sane and use int64_t/uint64_t

2015-07-18T18:30:43 < dongs> yeah thts what im doing for 64bit shit

2015-07-18T18:31:16 < dongs> its warning me because its ~not long~
2015-07-18T18:31:24 < zyp> oh, so just %d then
2015-07-18T18:31:31 < dongs> but sizeof(long) = 4 = sizeof(int32_t)
2015-07-18T18:31:35 < dongs> right
2015-07-18T18:31:41 < dongs> but I wonder why they even bother
2015-07-18T18:31:50 < dongs> %ld is for longlong?
2015-07-18T18:32:06 < zyp> no
2015-07-18T18:32:16 < zyp> %d is int, %ld is long and %lld is long long
2015-07-18T18:32:33 < dongs> but if long=int wahts the point
2015-07-18T18:32:43 < zyp> because that's not true on all platforms
2015-07-18T18:32:58 < zyp> on x86_64, int is usually still 32, while long is 64
2015-07-18T18:33:07 < dongs> fale
2015-07-18T18:33:43 < zyp> the conversion characters are not tied to the platform, so they mirror the fact that both int and long exists, even if they happen to be the same

2015-07-18T18:53:05 < emeb> openocd is hosted on sourceforge, which is currently down for maintenance.
2015-07-18T18:53:11 < dongs> emeb: haha.
2015-07-18T18:53:13 < emeb> and I don't have a copy of the docs

2015-07-18T19:33:00 < Ecco> Quick question: when you mass-produce something with an STM32 inside
2015-07-18T19:33:15 < Ecco> what's the typical procedure to get your code inside the devices?
2015-07-18T19:33:42 < Ecco> (I'm not talking about firmware update once the thing has shipped - I'm really wondering about the initial firmware flashing)
2015-07-18T19:34:12 < ReadError> Those tagconnects seems awesome
2015-07-18T19:34:24 < ReadError> seem*
2015-07-18T19:35:02 < emeb> My clients just use ST-Link + headers
2015-07-18T19:36:02 < Ecco> thanks emeb
2015-07-18T19:36:24 < Ecco> So you get some headers ready on the board, and use something stlink-capable to flash it?
2015-07-18T19:46:55 < emeb> Ecco: they just put a footprint for the 6-pin STLINK SWD header on the board
2015-07-18T19:47:02 < emeb> don't even install a header
2015-07-18T19:47:40 < emeb> just put the ST-Link cable in with a loose header, torque it to one side to ensure connection and then program via ST-Link Utility
2015-07-18T19:48:04 < emeb> saves cost of header on every board and discourages end-users from fooling with it.
2015-07-18T19:52:55 < emeb> OK - got my BMPs updated to latest firmware.
2015-07-18T19:53:19 < emeb> Interesting that the Blackmagic github no longer seems to host the hardware designs.
2015-07-18T19:54:03 < ReadError> any features the blackmagic offers over the st-link worth while?
2015-07-18T19:54:44 < emeb> ReadError: It runs a GDB server directly on the hardware
2015-07-18T19:55:16 < emeb> as opposed to the way OpenOCD works with the server running on the host talking low-level to the JTAG/SWD pod.
2015-07-18T19:55:46 < emeb> There are pros/cons to that.
2015-07-18T19:55:58 < Ecco> emeb: ok gotcha, just pads then :)
2015-07-18T19:56:04 < emeb> Ecco: yes
2015-07-18T19:56:21 < Ecco> Can this work for large volumes ?
2015-07-18T19:56:30 < Ecco> e.g. if I want to manufacture I don't know, 10k units
2015-07-18T19:56:31 < emeb> Ecco: define "large"
2015-07-18T19:56:45 < emeb> Ah well,  you might want to build a jig with pogo pins for that.
2015-07-18T19:56:53 < emeb> rather than doing it all by hand.
2015-07-18T19:57:02 < Ecco> I just looked up pogo pins
2015-07-18T19:57:03 < Ecco> allright
2015-07-18T19:57:08 < Ecco> but the process remains the same then?
2015-07-18T19:57:11 < Ecco> pads on PCB
2015-07-18T19:57:14 < emeb> My clients are still in the 100-1000 unit range.
2015-07-18T19:57:25 < Ecco> st-link software on a PC in the production chain
2015-07-18T19:57:29 < emeb> yes
2015-07-18T19:57:34 < Ecco> gotcha
2015-07-18T19:57:37 < Ecco> now the million dollar question
2015-07-18T19:57:45 < Ecco> how can I prevent my firmware from being stolen
2015-07-18T19:58:01 < emeb> you can turn on read protection.
2015-07-18T19:58:09 < emeb> that will discourage casual piracy
2015-07-18T19:58:12 < Ecco> (I guess it's a very common question)
2015-07-18T19:58:19 < Ecco> ok
2015-07-18T19:58:25 < emeb> but for determined pirates with resources you can't protect.
2015-07-18T19:58:36 < Ecco> Yeah
2015-07-18T19:58:43 < Ecco> A friend of mine worked on SIM cards
2015-07-18T19:58:46 < emeb> ie - if they have access to decapping equipment and SEM then you're sunk.
2015-07-18T19:58:58 < Ecco> and told me about the incredible ways people were dumping the internal firmware
2015-07-18T19:59:02 < Ecco> indeed
2015-07-18T19:59:41 < Ecco> Is piracy a common issue in hardware?
2015-07-18T19:59:52 < emeb> my advice: don't worry about it. Chances are that your product isn't such hot-shit that anyone will care to pirate it.
2015-07-18T20:00:08 < Ecco> yeah, that's pretty much what I thought
2015-07-18T20:00:22 < emeb> turn on the read protect and be happy. :)
2015-07-18T20:00:27 < Ecco> It's good to konw there's a way to prevent easy dumping of the fw though
2015-07-18T20:00:36 < Ecco> so thanks for that

2015-07-18T20:56:14 < emeb> yes

2015-07-18T21:00:40 < chickensk> so can you tell me how to do it? :D I am lost, so many registers and plls
2015-07-18T21:00:48 < chickensk> i use libopencm3 if that helps
2015-07-18T21:04:49 < Rickta59> you might download the stm32cubemx stuff and use it to configure the clock then look at the source code it generates to mimic it in your libopencm3 code

2015-07-18T21:58:11 < bradfirj> Is there a functional Ethernet driver in libopencm3 or am I better off looking at ST's code
2015-07-18T21:58:31 < PaulFertser> libopencm3 driver worked fine for me.
2015-07-18T21:58:52 < PaulFertser> With stm32f107
2015-07-18T21:59:08 < bradfirj> Thanks
2015-07-18T21:59:26 < bradfirj> Now to figure out the PHY
2015-07-18T21:59:37 < bradfirj> any resources to hand? Otherwise I'll google for myself
2015-07-18T22:00:15 < karlp> you can come hassle us in #libopencm3 if you like, but there's just so few common cheap dev boards with ethernet around that not many people have tested them
2015-07-18T22:00:58 < bradfirj> Yeah it's going to require a build before I can even start hacking code
2015-07-18T22:01:00 < bradfirj> Frustrating
2015-07-18T22:01:18 < bradfirj> We're doing a feasibility test of running Ethernet rather than USB between the device and host
2015-07-18T22:02:06 < bradfirj> Reason being there can be the desire for the device to be remote in certain situations and power over Ethernet would also be an interesting development
2015-07-18T22:06:09 < bradfirj> The F407 discovery board has an Ethernet MAC, I have a few of those in my drawer, might see if I can hack together a PHY and breadboard it
2015-07-18T22:07:37 < karlp> PoE is a lot more than just ethernet remember
2015-07-18T22:08:28 < bradfirj> That's blue sky possibilities, right now I think the ability to extend the device's range over ethernet (think media-converters and fibre, or maybe further with L2 trunking at the network layer)

2015-07-18T22:16:30 < bradfirj> Neat, it has the PHY MCU and the osc onboard
2015-07-18T22:16:41 < bradfirj> http://www.wvshare.com/product/DP83848-Ethernet-Board.htm (for anyone interested)
2015-07-18T22:17:12 < emeb> right - the motherboard brings out the ethernet to a socket for that.

2015-07-18T22:18:57 < emeb> http://www.wvshare.com/product/Open407V-D-Standard.htm
2015-07-18T22:19:28 < emeb> or you might just be able to use jumpers from the disco to the ethernet board.
2015-07-18T22:19:41 < bradfirj> You know at that price
2015-07-18T22:19:53 < bradfirj> I might well just put a 90 degree socket on my PCB and buy a batch of those PHY modules
2015-07-18T22:20:01 < bradfirj> and just plug them in at assembly

2015-07-18T22:20:18 < bradfirj> Thanks for the link to the big board
2015-07-18T22:20:21 < bradfirj> It was escaping me
2015-07-18T22:20:31 < emeb> they've got a lot to sift through
2015-07-18T22:21:33 < emeb> I was able to bring up the ST ethernet demo on that combo w/o issues.
2015-07-18T22:21:51 < emeb> of course it uses their StdPeriph libs, not libopencm3
2015-07-18T22:22:16 < bradfirj> Of course I'm being awkward as possible and using openOCD, linux and gcc
2015-07-18T22:22:19 < bradfirj> just to be annoying
2015-07-18T22:22:30 < emeb> that's what I use too
2015-07-18T22:22:33 < bradfirj> So getting StdPeriph and libopencm3 to work are likely to be equally hacky
2015-07-18T22:22:50 < emeb> took a bit of work to get the ST demo code to compile, but once it did everything worked.
2015-07-18T22:22:59 < bradfirj> You use a stock makefile or is there a fancy generator thingy floating about
2015-07-18T22:23:10 < emeb> I've got my own makefile
2015-07-18T22:23:30 < emeb> set up for the way I like to build the source hierarchy
2015-07-18T22:24:02 < bradfirj> :nods: It's all tape and glue over here

2015-07-19T04:22:35 < Lux> okay, thanks
2015-07-19T04:23:06 < Lux> btw do you guys have some example project for a stm32f4 in c++
2015-07-19T04:23:38 < Lux> i started porting some stuff and seem to be doing it wrong
2015-07-19T04:25:23 < zyp> porting what?
2015-07-19T04:25:54 < zyp> my stuff is all c++, but I'm not sure it's what you're looking for
2015-07-19T04:28:36 < Lux> just some stuff from ardino to stm32
2015-07-19T04:28:45 < Lux> *arduino
2015-07-19T04:29:00 < Lux> or teensy 3.1
2015-07-19T04:29:21 < Lux> zyp: do you have a github repo ?
2015-07-19T04:29:49 < Lux> i'm just a bit inexperienced with how all the c++ internals work
2015-07-19T04:30:22 < Lux> usually i do all my projects in c
2015-07-19T04:30:44 < zyp> not github, but I have a repo with a bunch of stuff elsewhere, you can take a look at the various branches here: http://cgit.jvnv.net/laks_demo/refs/
2015-07-19T04:30:59 < zyp> but if you're inexperienced with c++, that's probably not what you want
2015-07-19T04:31:59 < Lux> ya it's more about linker stuff and how the variables are initialized
2015-07-19T04:32:16 < zyp> oh, right
2015-07-19T04:32:18 < Lux> somehow i see stuff that shouldn't happen from what i learned
2015-07-19T04:32:31 < zyp> http://cgit.jvnv.net/laks/tree/startup/entry.cpp
2015-07-19T04:32:45 < Lux> like the default constructor is called, but not all private vars are initialized to zero
2015-07-19T04:33:18 < zyp> sounds like .bss initialization is missing then
2015-07-19T04:33:29 < zyp> but that sounds weird
2015-07-19T04:33:46 < Lux> yeah, global objects are fucked too, so that would make sense
2015-07-19T04:33:55 -!- KreAture_ is now known as KreAture_Zzz
2015-07-19T04:34:21 < zyp> the main difference between C and C++ startup is that the latter requires the init_array stuff for running global constructors
2015-07-19T04:35:20 < zyp> for C you mainly have to copy .data from ROM and clear .bss, for C++ you then also have to call global constructors if any
2015-07-19T04:36:02 < Lux> that stuff is missing in my setup
2015-07-19T04:36:09 < Lux> thanks for the pointer
2015-07-19T04:36:36 < Lux> c is really much simpler in that regard
2015-07-19T04:36:36 < zyp> no problem
2015-07-19T04:36:47 < zyp> not really
2015-07-19T04:36:58 < zyp> like I said, you still need .data and .bss initialization in C
2015-07-19T04:37:35 < zyp> and doing the constructors isn't really more complex than either of those
2015-07-19T04:38:07 < Lux> if you know what you are doing, yes :-)

2015-07-19T04:54:53 < Lux> zyp: if i understand it right you are using the entry.cpp file for startup together with the linker script instead of that provided startup.S ?
2015-07-19T04:56:30 < zyp> together with my own linker script, to be specific
2015-07-19T04:56:41 < Lux> btw is ther some literature on website where this whole startup/linking stuff is explained a bit ?
2015-07-19T04:56:42 < zyp> see http://cgit.jvnv.net/laks/tree/ld_scripts
2015-07-19T04:57:12 < Lux> that's the stuff i lacl the most
2015-07-19T04:57:20 < zyp> arm_flash_ram.ld defines the general rules, and is imported by each of the others which define specific memory sizes for a particular part

2015-07-19T05:18:53 < PeterM> dongs depends, if you're like 5v sure, but if you're like 24v fuck no
2015-07-19T05:19:19 < dongs> ya like 3V
2015-07-19T05:19:27 < diddly> anyone used the texane stlink program to write to the EEPROM area in stm32 devices?
2015-07-19T05:20:00 < dongs> are you talking about eeprom on L-series?
2015-07-19T05:20:15 < diddly> yes sorry
2015-07-19T05:28:23 < zyp> dongs, I'd say it's still going to be bad
2015-07-19T05:29:33 < zyp> keep in mind that if the led Vf is like 2V, what you're essentially doing by driving it directly from a pin is shorting that pin to 2V
2015-07-19T05:34:31 < PeterM> depends on dutycycle and trace length - with fast pwm freq and low duty cycle you're operating the pins fet in the ohmic region mostly anyway, and trace inductance will limit it a bit too
2015-07-19T05:35:23 < zyp> true
2015-07-19T05:36:09 < zyp> but then you're depending on dissipating the power that would have went to the current limiting resistor in the pin fet instead
2015-07-19T05:36:17 < zyp> which it's probably not rated for
2015-07-19T05:36:49 < PeterM> true, though, RMS power would be pretty low so its not likely to cause an issue
2015-07-19T05:37:58 < zyp> at 3.3V Vcc, I'd guess around half of what the led itself dissipates
2015-07-19T05:38:07 < zyp> (Vf around 2.2V)
2015-07-19T05:38:17 < PeterM> which chip dongs? could always just hook it to a discovery and try it out
2015-07-19T05:44:46 < dongs> haha
2015-07-19T05:45:03 < dongs> just F103, but its ok ill jsut get some inline resistors into the cable

2015-07-19T05:46:10 < dongs> i noticed only one of my led pins can do PWM anyway
2015-07-19T05:52:11 < dongs> even if it worked i'd have to ghetto software pwm it
2015-07-19T05:52:14 < dongs> so fuck that

2015-07-19T16:26:01 < dongs> I was very disappointed to say the least, considering how the delay has affected my plans, and all these non-communication. I recently contacted TG regarding a refund. To my horror, they couldn't offer a refund as they stated that the order "has been placed"
2015-07-19T16:26:01 < Laurenceb_> has it shipped to anyone?

2015-07-19T17:15:23 < ambro718> I have some troubles interfacing with SD cards (over SD interface, F4-Discovery). Four cards work, with one card there is a timeout in CMD8 (SEND_IF_COND), and with one other, the card returns a "checksum error" response to CMD55 (APP_CMD) that would precede ACMD41 (SEND_OP_COND). Both failures occur only the card has been inserted after power-up, and after that a second initialization attempt will work.
2015-07-19T17:16:37 < dongs> do you have a way to power cycle the card?
2015-07-19T17:17:19 < ambro718> I guess so, by playing with the wires

2015-07-19T21:17:18 < Tectu> When I understand this I2C peripheral correctly I start transmitting a byte by setting the START byte in CR1 to 1, right?
2015-07-19T21:17:19 < Tectu> I2C1->CR1 |= I2C_CR1_START;
2015-07-19T21:17:29 < Tectu> then it transmits the byte from the DR register. is that correct?
2015-07-19T21:18:06 < Tectu> now, next thing I do is waiting until the BUSY flag in SR2 is cleared so I know that the byte was sent. However, the BUSY flag never gets cleared. When I dont wait for the flag and just add a delay I see on my scope that the data is being transmitted continiously.
2015-07-19T21:18:37 < Tectu> The RM says that the BUSY flag is cleared after a STOP condition was detected. Do I have to manually generate a stop condition after sending the byte or something?
2015-07-19T21:18:41 < Tectu> This is all master transmit mode.
2015-07-19T21:26:05 < barthess> Tectu: did you read errata on your MCU?
2015-07-19T21:26:39 < Tectu> barthess, nope. STM32F407VGT if you know something you of your heading. searching for errata now
2015-07-19T21:27:04 < barthess> Tectu: that mcu has nasty bugs in I2C cell
2015-07-19T21:27:55 < Tectu> barthess, related to my issue?
2015-07-19T21:28:20 < barthess> Tectu: can not remember exactly, but looks similar
2015-07-19T21:28:59 < Tectu> 2.4.2 Start cannot be generated after a misplaced Stop
2015-07-19T21:29:04 < Tectu> barthess, does not look like my issue.
2015-07-19T21:29:07 < Tectu> barthess, neither do the other ones.
2015-07-19T21:30:57 < barthess> Tectu: I do not know
2015-07-19T21:31:07 < Tectu> :(
2015-07-19T21:31:57 < barthess> Tectu: may be you forgot to set some other configuration bits?
2015-07-19T21:32:43 < Steffanx> dont you need  byte trasnfer flag of sr1 Tectu?
2015-07-19T21:33:26 < Tectu> barthess, can you take a look at my code?  http://paste.ugfx.org/show/0bdcfd8aa4
2015-07-19T21:33:29 < Steffanx> doesnt busy mean the i2c bus is busy?

2015-07-19T21:33:47 < Tectu> barthess, pins are set up correctly. Stuff is send continiously when line 40:42 are commented
2015-07-19T21:34:00 < Lux> maybe you'll find some pointers there
2015-07-19T21:34:05 < Tectu> Steffanx, looking...
2015-07-19T21:34:07 < Tectu> Lux, thanks
2015-07-19T21:34:18 < Tectu> Steffanx, not sure. note that I have no slave connected. just scoping that bitch
2015-07-19T21:34:41 < Rickta59> the master is expecting a response no?
2015-07-19T21:34:41 < Steffanx> oh, no.. that's what you do after you sent a byte, you re still "starting"
2015-07-19T21:34:42 < Tectu> Steffanx, does it wait for ACK?
2015-07-19T21:34:57 < Steffanx> not?
2015-07-19T21:35:10 < Tectu> Steffanx, wut?
2015-07-19T21:35:32 < Tectu> Steffanx, I2C_CR1_START is cleared by hardware after it was generated, no?
2015-07-19T21:35:33 < Steffanx> dont you send a start, then wait for everything, busy and ready and stuff, and then start transmitting?
2015-07-19T21:35:43 < barthess> Tectu: debugging I2C without connected slave is bad idea
2015-07-19T21:36:16 < Steffanx> also https://github.com/libopencm3/libopencm3-examples/blob/master/examples/stm32/f1/other/i2c_stts75_sensor/stts75.c
2015-07-19T21:36:25 < Steffanx> but not sure how "good" that is, but at least its pretty low level
2015-07-19T21:37:15 < Tectu> Steffanx, oh, you meant I want to check for TxE, not for BUSY?
2015-07-19T21:37:27 < Tectu> Steffanx, is it really waiting for ACK?
2015-07-19T21:39:23 < Steffanx> no?
2015-07-19T21:40:45 < barthess> Tectu: I would recommend to connect some simple slave IC

2015-07-19T22:22:34 < diamondman> Hello everyone. I have an STM32 M3 that is giving me pain. I configured the USART and I can write characters. I am unable to receive. However when I transmit to the USART it reports that it received data, and the payload is the last byte I sent.
2015-07-19T22:23:48 < diamondman> I have tried this with my own code, with sample code from the CMSIS, and with various snippets from around the net that directly touch the registers instead of using CMSIS's insane methods

2015-07-19T22:52:17 < Tectu> so ST decided to put the I2C of the touchscreen and the audio chip on the same pins on the F7 discovery
2015-07-19T22:57:01 < qyx_> is that problem?
2015-07-19T23:01:00 < Taxman> Tectu: The audio chip? I2S?
2015-07-19T23:03:03 < Tectu> Taxman, the control interface. the audio goes through I2S.
2015-07-19T23:03:20 < Taxman> i2c, too?
2015-07-19T23:03:37 < Tectu> what is your question?
2015-07-19T23:03:37 < Taxman> i2c has subadresses, so this is no problem
2015-07-19T23:03:51 < Tectu> yes, of course not. It is just fuckly, that is all
2015-07-19T23:04:05 < Taxman> the audio control interface and the touchscreen chip both speak i2c
2015-07-19T23:04:08 < Taxman> ok
2015-07-19T23:04:11 < Tectu> yes, it is no issue at all.
2015-07-19T23:04:15 < Tectu> just meh
2015-07-19T23:04:27 < Tectu> people should not screw with my touchscreen interfaces
2015-07-19T23:05:00 < Taxman> hehe ok
2015-07-19T23:05:16 < Taxman> but ugfs seems to support audio too?
2015-07-19T23:05:24 < Tectu> yes
2015-07-19T23:05:28 < Tectu> both input and output
2015-07-19T23:05:34 < Taxman> maybe an audio driver for the F7 DISCO Audio?
2015-07-19T23:05:35 < Tectu> with support for hardware codecs
2015-07-19T23:05:43 < Tectu> yes, that is on the ToDo list.

2015-07-19T23:17:48 < diamondman> Does anyone know if there is any kind of weird loopback mode on the STM32 chips that may be enabled?
2015-07-19T23:19:42 < RaYmAn> that's a incredibly cryptic question - what are you actually seeing? =P
2015-07-19T23:22:29 < diamondman> RaYmAn: I set up my USART. I can transmit from the STM32 to my PC over RS232 (there is a max chip). I do not receive data from the computer. Any time I transmit data, the USART reports that it has received data and that data is the last thing I transmitted.
2015-07-19T23:23:17 < diamondman> RaYmAn: Shit, I forgot to ask if there was a *USART* loopback, sorry for the super vague question lol
2015-07-19T23:28:43 < RaYmAn> the loopback behavior is something I've certainly seen before
2015-07-19T23:30:03 < diamondman> RaYmAn: It is bugging me super hard. I can not seem to find any one else who is having this. It happens when I run CMSIS sample code too. One friiend suggests I go triple check that the rx and tx pins are not attached somehow
2015-07-19T23:30:27 < RaYmAn> yeah, I was actually seeing it in smartcard mode where you do use the same pin for both tx and rx

2015-07-19T23:33:24 < diamondman> interesting. I do not think I am ever receiving data form the PC. And in my case, RXNE is asserting as soon as I transmit.
2015-07-19T23:33:42 < RaYmAn> did you enable both TX and RX transmitters?
2015-07-19T23:33:57 < diamondman> sorry, as soon as the tc signal comes in
2015-07-19T23:35:02 < RaYmAn> a lot of code seem to do an immediate read after each write to DR
2015-07-19T23:37:15 < RaYmAn> diamondman: are you checking the overflow flag?
2015-07-19T23:37:55 < RaYmAn> if that flag gets set any further bytes won't be received, so if it gets set by the write to DR (somehow), you won't receive any bytes until the appropiate SR is read and DR is read

2015-07-20T03:01:40 < PeterM> first troll problems imgur keeps signing me out
2015-07-20T03:02:40 < dongs> yeah i fucking hate that
2015-07-20T03:02:53 < dongs> sometimes if you goto yourname.imgur.com it works but /all/ doent work
2015-07-20T03:03:02 < dongs> sometimes clicking signin just signs in anyway without stuff
2015-07-20T03:03:11 < dongs> oh, im logged out too
2015-07-20T03:03:16 < dongs> they must have fucked with some openid trash again
2015-07-20T03:03:38 < dongs> yea and just cilcking signin wihtout actually going through the process worked.

2015-07-20T06:17:26 < talsit> what do you use as a carrier?
2015-07-20T06:18:24 < talsit> i'm just setting up our machine
2015-07-20T06:18:29 < talsit> did my first bond :)
2015-07-20T06:18:54 < talsit> why? because i want to try to wire bond some resistors
2015-07-20T06:19:19 < talsit> reduce capacitance
2015-07-20T06:19:40 < talsit> soldering kinda sucks for application
2015-07-20T06:20:16 < talsit> a lot less than by soldering
2015-07-20T06:21:57 < talsit> well, for the full picture, we've got a TIA that measures pA, but we're limited at the moment by the capacitance of the feedback resistor, which, on its own is about 30-40fF, but when its soldered it's about 100fF
2015-07-20T06:23:10 < talsit> that's a 3-sided cap resistor, the 1-sided cap resistors have less initial capacitance, and wirebonding probably has little effect
2015-07-20T06:23:12 < talsit> why?
2015-07-20T06:23:35 < talsit> which we are planning
2015-07-20T06:23:51 < talsit> all the cool kids, as in, all the commercial products out there of this type
2015-07-20T06:24:26 < talsit> molecular devices axopatch headstage are all wirebonded discretes
2015-07-20T06:24:39 < talsit> physical: 1002, resistance: 1G
2015-07-20T06:25:04 < talsit> no, 1002
2015-07-20T06:25:42 < talsit> dunno, as i said, i just did my first bond this morning, we're going to measure it this week
2015-07-20T06:26:49 < talsit> no, because we first did prototypes and then we measured to see where our bottleneck was
2015-07-20T06:27:16 < talsit> we saw that solder was adding a lot of capacitance and we are testing new things to see if we can reduce that
2015-07-20T06:29:47 < talsit> we'll measure to see
2015-07-20T06:29:52 < talsit> thanks for the link

2015-07-20T12:32:52 < Tectu> hi
2015-07-20T12:34:51 < PeterM> gday m8
2015-07-20T12:35:27 < Fleck> morning!
2015-07-20T12:40:23 < Tectu> am I doing it right?  http://paste.ugfx.org/sores/99d72c7fc3e2/d763d0e8ef09.jpg
2015-07-20T12:41:23 < Fleck> don
2015-07-20T12:41:32 < Fleck> don't have LA? :)
2015-07-20T12:42:01 < Tectu> I have an LA. but for getting I2C up and running scope is 1000 times better
2015-07-20T12:42:27 < Tectu> besides that, my scope does this:  http://paste.ugfx.org/sores/7505d64a54e0/afcd141ba1ae.jpg
2015-07-20T12:42:57 < PeterM> im nto entirely convinved
2015-07-20T12:43:37 < PeterM> once you have your electronics down pat, an LA >scope
2015-07-20T12:43:49 < Fleck> :D +1 PeterM
2015-07-20T12:44:23 < ReadError> eh for getting it working a scope is nice
2015-07-20T12:44:27 < ReadError> since live view
2015-07-20T12:44:37 < Fleck> yep
2015-07-20T12:44:52 < PeterM> i mean, if you have a 200k pullup on your I2C, scope is great to tell you you fucked up, but for looking at the data, LA
2015-07-20T12:45:21 < Tectu> PeterM, there are cases where LA > scope and cases where Scope > LA. Before your I2C stuff is working properly and you are sure that the data you send is the correcty stuff with correct waveforms you use your scope and to debug the actual communication you go LA, in my opinion.
2015-07-20T12:45:30 < Tectu> PeterM, of course.
2015-07-20T12:45:43 < Tectu> PeterM, the last screenshot I posted is just helpful for doing both at once during early stage ;)
2015-07-20T12:45:59 < Tectu> also, you have the feature, why not using it....
2015-07-20T12:46:14 < PeterM> however i do also understand that during prototyping you're probably probing your board a bunch wiht the scope anyway, so it isn't much of a stretch to use your scope as an LA
2015-07-20T12:47:18 < ReadError> http://i.snag.gy/liic2.jpg
2015-07-20T12:47:26 < ReadError> i did that yesterday actually ;)
2015-07-20T12:48:11 < Tectu> lol
2015-07-20T12:48:20 < PeterM> ReadError, 1000z or 4000 series?
2015-07-20T12:48:25 < ReadError> 1000z
2015-07-20T12:48:43 < ReadError> im not doing anything fancy but the 4 channels is nice
2015-07-20T12:48:48 < ReadError> riglol'd
2015-07-20T12:49:27 < PeterM> the 1000z is nice but i miss controls per channel - i guess thats the prioce you pay for 4ch on babbys first oscope
2015-07-20T12:50:25 < ReadError> yea the price on them is pretty great for what you get
2015-07-20T12:52:19 < PeterM> agreed - i bought one and made a DC psu for it so i had a portable scope
2015-07-20T12:56:00 < Tectu> portable scope? Wut?
2015-07-20T12:57:11 < PeterM> ya know, like a scope that can be like... not on a bench?
2015-07-20T12:57:28 < Taxman> ohhh is my TDS2024 oldfashioned
2015-07-20T12:58:56 < PeterM> psshh, 4ch and 200mhz is good enough for a large amount of stuff
2015-07-20T12:58:57 < Tectu> Hi Taxman
2015-07-20T12:59:10 < Tectu> PeterM, only had the money for 2 ch :/
2015-07-20T12:59:36 < karlp> Tectu: needs to keep his website up more than he needs a scope or an LA
2015-07-20T13:00:39 < PeterM> Tectu, yeah, the MSO-X series is spensive as fuck - decent wuality tho
2015-07-20T13:00:44 < Taxman> PeterM: Yes, i use it to detect electrical problems. for logic analysis it is not very useful
2015-07-20T13:00:46 < Tectu> PeterM, indeed
2015-07-20T13:01:22 < Tectu> PeterM, after all I prefered to get a 2ch 200MHz scope instead of a 4ch 100MHz
2015-07-20T13:01:59 < Tectu> PeterM, and when I need more there are plenty of the the MSO-X 3000 series at my disposal (university)
2015-07-20T13:02:17 < Fleck> I would get 4x 100MHz :D
2015-07-20T13:02:51 < PeterM> i canjnot justify the price for a DSOX3012A, it is the same price as a tek mdo3012 which imho is a much btter unit
2015-07-20T13:03:28 < Tectu> PeterM, not gonna argue on that.
2015-07-20T13:04:59 < PeterM> i do like the waveform updages per second o nthe DSOX series, but memory is limited

2015-07-20T18:15:43 < aandrew> for smaller systems a resistor divider is fine. for hairier systems you might want to tie it to a regulator

2015-07-20T18:23:44 < Tectu> I will let you know after I tried using it tonight
2015-07-20T18:25:09 < Tectu> correction: it is the same as on the F3.
2015-07-20T18:25:17 < Tectu> hence it might only be completely new to me.
2015-07-20T18:27:16 < zyp> didn't somebody comment on the F3 I2C peripheral before?
2015-07-20T18:27:21 < zyp> jpa- perhaps?
2015-07-20T18:27:39 < ReadError> is the F3 one better than F1/F4?
2015-07-20T18:27:48 < zyp> that's what I wonder
2015-07-20T18:28:00 < zyp> I haven't used it myself, but I remember somebody talking about it once
2015-07-20T18:28:18 < Tectu> I assume this is what people refer to I2Cv2 then?

2015-07-20T18:36:31 < zyp> maybe that's just because nobody have used it yet :p
2015-07-20T18:36:45 < jpa-> could be :P
2015-07-20T18:37:19 < jpa-> atleast GPIOv2 managed to fix a lot of the shortcomings of the original one
2015-07-20T18:37:43 < zyp> true
2015-07-20T18:37:59 < Tectu> jpa-, can you list a few?
2015-07-20T18:38:14 < zyp> the major one is AF mapping
2015-07-20T18:38:21 < jpa-> for first, the fact that you couldn't really choose between different functions on same pin
2015-07-20T18:38:39 < jpa-> some useless USART signal you don't even use could block some important pin
2015-07-20T18:38:43 < zyp> the remap functionality on F1 is pretty dumb compared to the flexibility of all the other chips
2015-07-20T18:39:00 < Tectu> I only used the I2C on the F4 so no idea about that
2015-07-20T18:39:04 < Tectu> I assume that problem is F1 only then?
2015-07-20T18:39:15 < jpa-> i also kind of like the registers of gpiov2 better also
2015-07-20T18:39:35 < jpa-> having otype/ospeed/etc. separately.. though if they were 4 bits per pin it would be easier to read in debugger
2015-07-20T18:39:50 < zyp> yeah, and then pullup control is better
2015-07-20T18:41:51 < Tectu> all I remeber from F1 is ´dont use F1´
2015-07-20T18:42:39 < jpa-> i'm planning to use F1 soon again, though
2015-07-20T18:42:46 < jpa-> it's cheap and i've got used to the quirks

2015-07-20T20:45:56 < kakimir_> old one works for opening stuff quickly and new one opening stuff with delays
2015-07-20T20:47:16 < jpa-> isn't alt-f2 simpler for quick opening?
2015-07-20T20:47:33 < qyx_> it is
2015-07-20T20:48:46 < kakimir_> yes
2015-07-20T20:48:53 < kakimir_> depends of your machine
2015-07-20T20:49:12 < kakimir_> it clearly does some seek process
2015-07-20T20:50:02 < kakimir_> nm --print-size --size-sort --radix=d main.o
2015-07-20T20:50:06 < kakimir_> this does something

2015-07-20T21:15:31 < Tectu> kakimir_, radix is the base. You might want to use base 16 for this kind of stuff

2015-07-20T21:22:37 < Tectu> I asume for an AVR that should be sub 1k, no?
2015-07-20T21:22:47 < Tectu> maybe even sub 500 bytes?
2015-07-20T21:22:52 < jadew> it should be sub 100

2015-07-20T22:55:04 < kakimir_> jlink clone is under 10$
2015-07-20T22:55:18 < Tectu> STLink original is 23$ or free if you have a discovery board
2015-07-20T22:55:23 < kakimir_> but you need to have stream of them as driver can kill them anytime

2015-07-20T23:01:26 < Tectu> fuck fucking st fuckers fuck fuck fuck
2015-07-20T23:01:37 < Tectu> they provide an I2C timing calculation spreadsheet (MS excel) for the F3 series
2015-07-20T23:02:01 < Tectu> that would work nicely for the F7 too but the max i2cclk frequency is set to 72MHz because it cannot be faster on F3 anyway it appears
2015-07-20T23:02:10 < Tectu> so a dialog pops up tells you to not exceed those 72MHz

2015-07-20T23:40:37 < kakimir_> on that thing of yours
2015-07-20T23:41:40 < Tectu> kakimir_, well it is a standard JTAG key, all software (eg. OpenOCD) can handle it
2015-07-20T23:42:20 < karlp> jlink clone can only be kille dby its drivers if you use the segger drivers
2015-07-20T23:42:54 < karlp> I actually turned on the seger linux software to see what it did and it actually just auto upgraded the firmware on my clone :)
2015-07-20T23:43:16 < kakimir_> there is option to use other driver?
2015-07-20T23:43:28 < karlp> sure, openocd works just fine with it.

2015-07-21T00:54:38 < kakimir_> https://drive.google.com/file/d/0B2GcdpJiNGfKWFFhN3hRdVJkLUU/view?usp=sharing how about something more classical
2015-07-21T00:54:41 < ReadError> the blue/black stuff works really well in direct sunlight
2015-07-21T00:55:12 < ReadError> kakimir_ hehe yea, need a bit more pixel :)
2015-07-21T00:55:30 < Tectu> ReadError, I worked on a project/product with an OLED that was like 320x240 but that was NDA crap and I dont know the panel number, sorry. I just got the HW and hooked up the JTAG
2015-07-21T00:55:41 < Tectu> kakimir_, is that yours?
2015-07-21T00:56:01 < kakimir_> yes
2015-07-21T00:56:17 < Tectu> kakimir_, do you have a link to that display module for my personal notes?
2015-07-21T00:56:27 < Tectu> kakimir_, and is that a camera on the flat flex cable beind the display? o.O

2015-07-21T00:57:54 < ReadError> somewhat interesting
2015-07-21T00:58:04 < Tectu> ReadError, that is an LCD, not OLED
2015-07-21T00:58:11 < Tectu> ReadError, those white on blue things work nice, tho.
2015-07-21T00:58:18 < dongs> sup dongs
2015-07-21T00:58:32 < Tectu> ReadError, but usually four times more expensive than the black on green/yellow crap
2015-07-21T00:58:35 < Tectu> hello dongs
2015-07-21T00:58:42 < Tectu> dongs, used I2C on F3 before?
2015-07-21T00:58:48 < ReadError> yea Tectu noticed that
2015-07-21T00:58:52 < ReadError> e-Ink would be nice
2015-07-21T00:58:57 < dongs> aandrew: only one ddr3 chip here, 16bit. reference just uses a divider
2015-07-21T00:58:58 < ReadError> but imagine $$
2015-07-21T00:59:01 < Tectu> kakimir_, can you provide a link to that display module?
2015-07-21T00:59:07 < dongs> Tectu: yeah
2015-07-21T00:59:09 < Tectu> ReadError, money no issue?
2015-07-21T00:59:23 < Tectu> dongs, with Stdperiph/cube crap or register access directly?

2015-07-21T01:01:31 < ReadError> so if its reasonable
2015-07-21T01:01:44 < Tectu> ReadError, RA8835  <--  RA88xx controllers tend to be very nice

2015-07-21T01:02:39 < Tectu> dongs, meh
2015-07-21T01:02:46 < dongs> ther'es a couple constants for 400, 1.2mhz, etc
2015-07-21T01:04:43 < Tectu> dongs, F7 has same I2C peripheral as F3. ST provides a very neat Excel spreadsheet to calculate TIMINGR value. However, F3 max I2CCLK frequency is 72MHz. When you enter a larger number a dialog box yells at you. I need to be able to set a higher clock there.
2015-07-21T01:04:44 < ReadError> but for 64 or 72mhz ;/

2015-07-21T01:05:41 < ReadError> then re-export as .xls ?
2015-07-21T01:05:47 < Tectu> dongs, to quote <ReadError> its SUUUUUPER easy to unlock
2015-07-21T01:05:58 < Tectu> ReadError, did you try that? how does google docs handle VBA crap?
2015-07-21T01:06:12 < dongs> err, there's some .vba that unlocks any excel

2015-07-21T01:07:18 < dongs> if stonererror says it doesnt work then it doesnt
2015-07-21T01:07:26 < Tectu> a friend of mine tried to use some hex dump tool to extract a key thing and crap but not even that worked (not sure how skilled he really is)
2015-07-21T01:07:26 < dongs> i only have the aaaaaavba tool
2015-07-21T01:07:33 < ReadError> yea mine did the same thing

2015-07-21T03:01:17 < dongs> lol , you re actually using HAL_ shit?
2015-07-21T03:01:27 < emeb> meh
2015-07-21T03:01:45 < dongs> uart DMA or IRQ isnt THAT hard to setup
2015-07-21T03:01:55 < emeb> fscking ST has no StdPeriph for F7 - must use Cube crap
2015-07-21T03:02:02 < dongs> yeah i heard

2015-07-21T03:03:50 < aandrew> wow
2015-07-21T03:03:55 < dongs> are you overclocking stuff

2015-07-21T03:03:57 < Tectu> dongs, I even use CubeMX crap for timings generation, really
2015-07-21T03:04:01 < aandrew> I just looked at the HAL_UART_Transmit_IT() code
2015-07-21T03:04:04 < aandrew> almost lost my dinner
2015-07-21T03:04:11 < emeb> heh
2015-07-21T03:04:14 < dongs> i bet
2015-07-21T03:04:19 < aandrew> my god what the fuck is the point of it
2015-07-21T03:04:30 < Tectu> I scope my SCL and it is always 1.25MHz
2015-07-21T03:04:32 < dongs> to transmit IT
2015-07-21T03:04:41 < aandrew> no buffer, just takes your buffer, sets up the transmit and starts the interrupt-driven xfer
2015-07-21T03:04:44 < dongs> if you wanna transmit THAT, you better use some other code
2015-07-21T03:04:49 < aandrew> if it's not done transmitting the old buffer, it fails
2015-07-21T03:04:50 < emeb> buddy of mine looked at the HAL UART code and found a bunch of potential deadlocks
2015-07-21T03:04:53 < aandrew> what the fuck is the point of that
2015-07-21T03:05:22 < aandrew> yeah I can see working around this brain damaged implementation
2015-07-21T03:05:37 < aandrew> someone mentioned it here... they must have handed this shit off to an intern to implement
2015-07-21T03:05:52 < Tectu> aandrew, they actually did
2015-07-21T03:05:57 < dongs> all the pros just use keil devicepacks
2015-07-21T03:06:05 < Tectu> aandrew, at least with the StdPeriph I know for a fact that it was all intern work
2015-07-21T03:06:05 < dongs> which has their own retarded stm middleware
2015-07-21T03:06:35 < aandrew> I lurk in #libopencm3, wonder if that's any better
2015-07-21T03:06:47 < Tectu> use keil device pack middle ware crap on some nordic chip that was M0 or M0+

2015-07-21T03:07:45 < dongs> only installed it to get flash algorithms
2015-07-21T03:08:00 < dongs> time to dicknplace
2015-07-21T03:13:42 < Tectu> dongs, old I2C required to set bit whether you are in Sm or Fm (100kHz or 400kHz mode). New I2C crap does no longer have that. All done through TIMINGR, right?
2015-07-21T03:13:59 < dongs> i guess so man, did you even look at i2c examples in stdperiph?
2015-07-21T03:14:03 < dongs> thats all i needed and shit just worked.
2015-07-21T03:14:10 < dongs> if you cant figure it out, bitbang i2c is like 20 line sof code.

2015-07-21T03:52:07 < emeb> Interesting - F7 no longer has BOOT1 pin
2015-07-21T03:52:27 < emeb> BOOT0 is now BOOT and option bytes in flash have BOOT_ADD
2015-07-21T03:52:48 < emeb> so I guess it's possible to bypass the bootloader by tweaking BOOT_ADD

2015-07-21T04:04:43 < ccole> I've tried PaulFertser's STM32F7-Discovery support patches, and it appears to get a lot further in the programming function, but then fails with a timeout.
2015-07-21T04:10:09 < dongs> isnt that like a $900 board
2015-07-21T04:10:31 < dongs> i think onyl tectu can afford that

2015-07-21T05:46:03 < dongs> https://cdn.upverter.com/static/files/ROI_report_upverter_altium_2014-53555757.pdf
2015-07-21T05:47:16 < dongs> In terms of mouse clicks, using Upverter resulted in 6,900 actions while Altium required 9,800. The main reason behind this difference is Upverter.s modern and intuitive interface which always displays the most commonly used tools and critical information withinthe editor.
2015-07-21T05:47:21 < dongs> such bullshit
2015-07-21T05:47:26 < PeterM> We used two
2015-07-21T05:47:27 < PeterM> electrical  engineers  with  5-10  years  of

2015-07-21T05:47:37 < dongs> hahaha
2015-07-21T05:47:55 < dongs> well shit, he just needs to be on irc
2015-07-21T05:47:58 < PeterM> credibility gone
2015-07-21T05:47:58 < dongs> and he has all teh qualifications
2015-07-21T05:48:19 < dongs> some web EDA trash
2015-07-21T05:48:30 < dongs> The number of keystrokes used with Upverter totalled up
2015-07-21T05:48:31 < dongs> to 10,200 while Altium took 11,400 hits.
2015-07-21T05:48:35 < dongs> ??? how is that a bad thing
2015-07-21T05:48:41 < dongs> it should be mostly keypresses
2015-07-21T05:48:45 < dongs> and less clicks
2015-07-21T05:49:08 < dongs> THERE ARE 1.2 MILLION PARTS IN THE

2015-07-21T05:49:08 < dongs> DESIGNER, L
2015-07-21T05:49:10 < dongs> err wat
2015-07-21T05:49:18 < dongs> LIBRARIES DON.T COME WITH THE
2015-07-21T05:49:19 < dongs> PRODUCT.
2015-07-21T05:49:28 < dongs> have tehy not heard of altidong valut shit
2015-07-21T05:49:34 < dongs> er vault
2015-07-21T05:49:38 < dongs> they probly fucking pirated altidong
2015-07-21T05:49:43 < dongs> and complained "LOOK NO LIBS!!111
2015-07-21T05:49:55 < zyp> haha, wat
2015-07-21T05:50:15 < PeterM> dongs more like "I AM A BLAGGAR AND I DUNNO HOW TO HARDWARE LEMME TRY  ULTIAM"
2015-07-21T05:50:27 < dongs> Parts are easy to find, re-use, and fork, making it possible to start working on a new project right away without spending hours creating the parts that you need.
2015-07-21T05:50:37 < dongs> R2COM: you better try upverter then
2015-07-21T05:50:43 < dongs> it sounds absolutely amazing and better than altium
2015-07-21T05:50:50 < dongs> THE LINKAGE BETWEEN SCHEMATIC AND
2015-07-21T05:50:50 < dongs> LAYOUT IN ALTIUM IS ANNOYING.
2015-07-21T05:50:55 < dongs> ??????????????????????????????????????????????
2015-07-21T05:51:18 < dongs> WHEN YOU REPLACE A COMPONENT IN THE SCHEMATIC AND YOU UPDATE THE DESIGNATOR, IF YOU DIDN.T COPY OVER ITS UNIQUE IDENTIFIER BEFORE YOU DELETED IT, IT WON.T BE ABLE TO LINK BACK TO THAT PARTWHEN YOU SWITCH BACK TO THE LAYOUT
2015-07-21T05:51:19 < zyp> haha
2015-07-21T05:51:22 < dongs> what.
2015-07-21T05:51:25 < dongs> the.
2015-07-21T05:51:26 < dongs> never heard of component links menu???
2015-07-21T05:51:29 < dongs> fuck
2015-07-21T05:51:41 < dongs> so they basically got some altidong newb to make shit
2015-07-21T05:51:47 < dongs> and he said upverter was amaze!11
2015-07-21T05:52:17 < zyp> «upverter is nice because I'm too dumb to use altium»
2015-07-21T05:53:59 < aandrew> altium is nice
2015-07-21T05:54:02 < aandrew> pricey but nicey
2015-07-21T05:54:16 < PeterM> zyp, "Eric Evenchick, Hardware Designer, consultant and blogger"  -  the guyu they got to do the board in altium.
2015-07-21T05:54:52 < aandrew> R2COM: compared to what
2015-07-21T05:55:00 < aandrew> I have been an Eagle user for over 15 years
2015-07-21T05:55:10 < aandrew> used altium for a little over 3 months
2015-07-21T05:55:21 < zyp> R2COM, uh, I haven't really counted
2015-07-21T05:55:27 < aandrew> I'm well, well well ahead on Altium even on insane designs
2015-07-21T05:56:32 < aandrew> R2COM: what would you call 14 layer, blind/buried microvias, controlled impedance/matched length?
2015-07-21T05:58:05 < aandrew> I haven't foudn it slow
2015-07-21T05:58:17 < aandrew> what I *do* hate about altium is that for a $5k package it's fucking crashy as fuck
2015-07-21T05:58:20 < zyp> hmm, I'm counting five designs that I've done in altium, plus a few revisions of some, and then a couple that I never finished
2015-07-21T05:58:29 < aandrew> its svn support is shit
2015-07-21T05:58:34 < aandrew> its "vault" is terrible
2015-07-21T05:58:40 < PeterM> R2COM, horrible grid? which grid is bad? since it is user configurable, wouldn't that make it a horrible user?
2015-07-21T05:58:51 < aandrew> the ONLY saving grace for altium is that when it *does* crash it does not take your work with it
2015-07-21T05:58:58 < dongs> eh
2015-07-21T05:58:59 < zyp> aandrew, sure it does
2015-07-21T05:59:00 < aandrew> which I think is quite frankly amazing
2015-07-21T05:59:04 < dongs> altium doesnt crash a lot
2015-07-21T05:59:10 < dongs> some versions d o
2015-07-21T05:59:14 < dongs> i keep it up to date
2015-07-21T05:59:18 < dongs> and ~latest generalyl dos not
2015-07-21T05:59:18 < aandrew> dongs: it crashes like crazy when doing a lot of shoving around of diff pairs
2015-07-21T05:59:19 < dongs> does
2015-07-21T05:59:30 < dongs> eh, ive done that, not had any problem
2015-07-21T05:59:34 < dongs> i bet if anything its your shitty GPU
2015-07-21T05:59:37 < dongs> where does it crash?
2015-07-21T05:59:39 < zyp> I think altium has crashed like two times for me, and I lost work both times
2015-07-21T05:59:39 < dongs> D3DScene.pas?
2015-07-21T05:59:40 < dongs> lolo
2015-07-21T05:59:41 < aandrew> R2COM: I used to love orcad... back in the PCB/SDT386+ days
2015-07-21T05:59:46 < aandrew> when the went windows it went shit
2015-07-21T06:00:10 < dongs> < aandrew> when the went windows
2015-07-21T06:00:11 < dongs> but
2015-07-21T06:00:12 < aandrew> dongs: most times when you shove traces around it does a decent job and then goes tits up
2015-07-21T06:00:22 < dongs> then tehy kept all the dos code in it
2015-07-21T06:00:27 < dongs> so even 2015 version is still slow as fuck
2015-07-21T06:00:29 < dongs> to draw anything
2015-07-21T06:01:12 < PeterM> a good feature http://i.imgur.com/V4LBZmF.png - useful for extended history  etc
2015-07-21T06:01:13 < aandrew> i actually think using the 3d engine to do layout is brilliant
2015-07-21T06:01:18 < dongs> orcad
2015-07-21T06:01:19 < aandrew> just too bad they used D3D instead of OGL
2015-07-21T06:01:37 < dongs> aandrew: u . h .
2015-07-21T06:01:41 < aandrew> PeterM: yes, never had to worry about that too much
2015-07-21T06:01:44 < dongs> no its good they used d3d because it actually works
2015-07-21T06:01:56 < aandrew> whenever it crashed it was the router that crashed, but the layout engine stayed going
2015-07-21T06:01:58 < dongs> does opengl even have a modern standard
2015-07-21T06:02:00 < dongs> for 2015
2015-07-21T06:02:10 < dongs> that covers features introduced in graphics cards in the last 2 decades?
2015-07-21T06:02:22 < dongs> last I checked opengl had it all via some 'extensions" where every vendor could do wahtever the fuck they wanted
2015-07-21T06:03:13 < dongs> ohh

2015-07-21T06:09:07 < zyp> dongs, actually, it looks like opengl is actually ahead for the moment, until dx12 comes out
2015-07-21T06:12:59 < PeterM> zyp i thought ogl performance was allround worse than dx on modern consumer graphics chipsets

2015-07-21T06:20:24 < zyp> kinda irrelevant either way, altium wouldn't release a version that wouldn't run on typical business computers, which tends to have old as fuck hardware
2015-07-21T06:21:29 < zyp> I'm not talking about altium specificly
2015-07-21T06:22:22 < zyp> writing software against the latest APIs means that it requires the latest hardware to run, which is kinda unrealistic in a business setting

2015-07-21T08:07:08 < dongs> What is the shipping status?
2015-07-21T08:07:16 < englishman> I just called Torquing Group...after a number of rings the call was answered by a girl that apparently works in 'Research & Development'. I asked when the Zano would be ready for despatch, she couldn't give an answer and sounding surprised she questioned how I was able to obtain the telephone number.
2015-07-21T08:07:16 < englishman> I questioned further and she then commented that the people that could give an answer were in a separate building/department and that she couldn't put me through or find out herself by putting me on hold, she asked me to send an email.
2015-07-21T08:07:16 < englishman> ...the office sounded very quiet in the background!

2015-07-21T09:06:38 < rkreis_> is wrong with that?
2015-07-21T09:06:53 < rkreis_> you don't manually route 6 layers, do you?
2015-07-21T09:08:04 < dongs> er it looks pretty ugly thats al
2015-07-21T09:08:10 < dongs> i would manually route it yes
2015-07-21T09:09:04 < jpa-> the more layers, the easier to route; so if you'd manually route 2, why not 6? :P
2015-07-21T09:09:26 < jpa-> but if it works, who cares about ugliness :)
2015-07-21T09:15:17 < PaulFertser> Regarding the problem ccole had with STM32F7 eval board, it's known that some earlier eval board revisions came with buggy stlink firmware. It should be upgraded to the latest one (007) to work.

2015-07-21T09:17:17 < PaulFertser> dongs: did he have enough clue to make autorouter length-match the ddr lanes? Any other obvious routing errors like letting power traces go too near sensitive analog or digital traces etc?
2015-07-21T09:18:39 < dongs> ohh buggy stdink
2015-07-21T09:18:43 < dongs> who would have thought!
2015-07-21T09:19:09 < PaulFertser> You know what else is (was, and likely will be) nasty about stlink?
2015-07-21T09:20:28 < dongs> do tell
2015-07-21T09:20:33 < dongs> that its closedsores???
2015-07-21T09:21:05 < PaulFertser> Lack of 16-bit reads and writes. Not needed for stm32s obviously, but leads to issues with some other parts that would work just fine otherwise.
2015-07-21T09:21:52 < PaulFertser> It's nasty even for stm32 when you consider that a CFI flash (or other peripheral that needs 16-bit writes) can be attached to the external bus.
2015-07-21T09:22:01 < dongs> pfft
2015-07-21T09:22:06 < dongs> its not a $500 jtag dongle
2015-07-21T09:22:09 < dongs> like j-link
2015-07-21T09:22:11 < dongs> or other proper shit
2015-07-21T09:22:19 < dongs> so why should i t support anything beyond whats required for stm32
2015-07-21T09:22:19 < PaulFertser> Thing is, it'd be trivial to implement.
2015-07-21T09:22:26 < PaulFertser> And it would help stm32 with cfi.

2015-07-21T11:42:59 < PeterM> but more old guys and people that cant dance
2015-07-21T11:43:50 < zyp> also, JTAG in itself is very irrelevant for modern programmers, it's just a thin transport protocol
2015-07-21T11:43:59 < zyp> all the hard stuff is the stuff layered on top of that
2015-07-21T11:44:11 < zyp> you'll probably want to read the ADIv5 spec for that
2015-07-21T11:44:58 < PointerToNull> zyp, thanks! I'll have a look.. So your advice is to start with ADIv5 spec and than move on to the JTAG protocol?
2015-07-21T11:45:34 < zyp> do you know anything about JTAG at all?
2015-07-21T11:46:24 < zyp> also, why do you care about JTAG specifically? I'd rather invest my time in SWD if I were writing anything from scratch
2015-07-21T11:47:17 < zyp> JTAG in itself is almost as simple as SPI, the entirety of the complexity lies in whatever protocol you layer on top of that
2015-07-21T11:47:35 < zyp> SWD is an alternative and more modern transport, for the same commands

2015-07-21T11:52:32 < PointerToNull> zyp, no I have no expirience with JTAG yet, I though this would be nice to understeand expecially because JTAG isn't more compatible? (with old micros I mean)
2015-07-21T11:53:45 < jpa-> i'm not sure if jtag knowledge is even very useful at all, unless you plan a career out of making jtag adapters
2015-07-21T11:54:16 < PointerToNull> Ah I don't have to debug with my project.. My goal for now is just to load a firmware from a usb key to an ARM micro
2015-07-21T11:54:19 < zyp> the part that's common between cortex-m and other families with JTAG is very small, since JTAG is just used as a transport
2015-07-21T11:54:44 < zyp> then you probably don't want to deal with JTAG at all, write a bootloader instead
2015-07-21T11:55:22 < zyp> don't waste your time implementing debugging protocols unless you're actually going to use it for debugging
2015-07-21T11:55:52 < PointerToNull> So what you think is the best way to do a small ARM micro programmer?

2015-07-21T12:19:48 < PointerToNull> zyp, thanks! I'll have a look in a bit.. These are link from st but are general for ARM architecture right? I mean, "I can program an Atmel" reading the pdfs?
2015-07-21T12:20:30 < zyp> no
2015-07-21T12:21:30 < zyp> there's no generic way at all to program ARM chips, even with JTAG/SWD, since each vendor have their own flash interface
2015-07-21T12:22:18 < zyp> the docs I linked you to documents a built in bootloader that every stm32 ships with, which can take simple commands through an USART to write specific memory blocks
2015-07-21T12:23:18 < zyp> if you want to go with JTAG/SWD, you'll first have to implement the transport layer, then you'll have to implement the ADIv5 stack on top of that, which will give you direct access to the microcontroller's memory space
2015-07-21T12:23:42 < zyp> then you'll have to write specific drivers for each vendor's flash controller
2015-07-21T12:25:01 < zyp> and since polling the flash controller through the debug port is slow, eventually you'll want to write a flashloader stub, which is a piece of code you load first, that takes memory you write to ram, and writes it to flash for you
2015-07-21T12:25:29 < zyp> there is a pretty huge difference in amount of work required there

2015-07-21T16:39:29 < Laurenceb> yup, he claims to talk to god, and receive "answers"

2015-07-21T16:40:34 < zyp> jpa-, I bet somebody routed it first, and then they got a DRC error due to having two unconnected grounds, so they connected them

2015-07-21T16:40:56 < jpa-> zyp: seems like vcc based on pinout, but yeah could be
2015-07-21T16:41:15 < jpa-> funny connector layout having multiple Vcc pins but only one gnd
2015-07-21T16:41:16 < kakimir_> what are in kde file browsers these + and - signs in file icon?
2015-07-21T16:41:22 < jpa-> but display connectors are always crap like that
2015-07-21T16:41:23 < Tectu> jpa-, what exactly is that? some display LVSD magic or something?

2015-07-21T16:43:08 < jpa-> it's not like it is the first result or anything
2015-07-21T16:43:48 < jpa-> basically for those silly people who enable "single click to open"
2015-07-21T16:44:29 < Tectu> my friend always yells at me when I dont enable that option
2015-07-21T16:44:56 < Tectu> ´´double clicking is so inefficient´´
2015-07-21T16:45:04 < Tectu> looks like he never had to just select a file without opening it...
2015-07-21T16:45:24 < jpa-> well you can select with different ways anyway..
2015-07-21T16:45:30 < jpa-> so it is just a matter of what you are used to
2015-07-21T16:45:35 < kakimir_> thanks for googling for me jpa!
2015-07-21T16:45:45 < jpa-> but of course every GUI should work like windows 95, because that is the right way (tm)
2015-07-21T16:46:00 < kakimir_> okay kde is great
2015-07-21T16:46:06 < kakimir_> this proofs it

2015-07-21T16:49:33 < mtbg> that templeos guy is jewish, not christian, and what is more fun is that the source of randomness he uses is a free running timer + keyboard events

2015-07-21T17:00:22 < dongs> i think they sent me the NT35whatever driver datasheet too
2015-07-21T17:00:28 < dongs> so I could fuck around wiht PWM generation for backlight
2015-07-21T17:00:44 < scrts_w> hmm, can you put the display datasheet somewhere? I am only interested in mechanical drawing at this point..
2015-07-21T17:00:55 < dongs> lets see, ithought i did
2015-07-21T17:01:20 < scrts_w> I probably lost your gdrive link
2015-07-21T17:01:21 < dongs> see /notice

2015-07-21T17:44:24 < Ecco> Hi guys :-)
2015-07-21T17:44:43 < Ecco> I'm comparing Cortex M0 between Atmel and ST

2015-07-21T17:45:22 < Ecco> Turns out, ST's M0s are more expensive than Atmel's M0+
2015-07-21T17:45:35 < Ecco> (I'm looking at 256K flash, 32K RAM)
2015-07-21T17:45:40 < Ecco> (prices from Mouser)
2015-07-21T17:45:44 < Ecco> That's weird, isn't it?

2015-07-21T17:49:31 < zyp> why?
2015-07-21T17:55:04 < Ecco> Well, I don't understand how something better can be cheaper
2015-07-21T17:55:12 < Ecco> I'm afraid there's a catch
2015-07-21T17:57:26 < Tectu> Ecco, prices of chips depend a lot on the demand etc.
2015-07-21T17:57:54 < Ecco> Oh, ok
2015-07-21T17:58:13 < Tectu> Ecco, I am no marketing guy as you now, but you can often get stuff with higher performance cheaper. Eg. the F407 used to be cheaper than the F405 although the F405 is EXACTLY and F407 without the ethernet just because the F407 was sold more
2015-07-21T17:58:36 < Tectu> (not 100% sure on the EXACTLY thing, but pretty sure that it is the same otherwise. Either way it is the same thing with less peripherals)
2015-07-21T17:58:59 < Ecco> Hmm, I understand
2015-07-21T17:59:21 < Ecco> Now is Atmel considered a reliable vendor?
2015-07-21T17:59:31 < Ecco> I have only heard good things about them
2015-07-21T17:59:55 < Tectu> I cannot judge that, sorry.
2015-07-21T18:00:02 < Tectu> better ask dongs, zyp, jpa- and other pros
2015-07-21T18:00:13 < _Sync_> we had supply issues with them

2015-07-21T18:07:56 < jpa-> Ecco: well, M0 vs. M0+ is probably just a small part of the price - the peripherals of each matter a lot more
2015-07-21T18:08:13 < jpa-> i haven't studied the differences between atmel vs. st on those parts
2015-07-21T18:08:25 < Ecco> Ok
2015-07-21T18:08:51 < Ecco> Supposedly both are pretty barebone
2015-07-21T18:08:55 < jpa-> and what Tectu said is also true, prices change a lot
2015-07-21T18:09:15 < Tectu> Ecco, might be worth having a look at FreeScale, afaik they have some very cheap M0(+) devices
2015-07-21T18:09:20 < jpa-> Ecco: do you have some part numbers?

2015-07-21T18:10:05 < Ecco> jpa-: Sure
2015-07-21T18:10:11 < Ecco> STM32F091CCT6 vs ATSAMD20E18A-MU
2015-07-21T18:10:50 < jpa-> looks about the same price on digikey
2015-07-21T18:11:12 < Ecco> Yeah, but the Atmel one is M0+
2015-07-21T18:11:23 -!- Abhishek___ is now known as Abhishek__
2015-07-21T18:11:39 < rkreis_> Ecco, then look at stm32l0, too
2015-07-21T18:11:42 < Ecco> And (the numbers are burried deep in the datasheet on the ST one) apparently the one from Atmel eats a lot less battery
2015-07-21T18:11:52 < Ecco> Yeah, but STM32L0 have very very little RAM/FLASH
2015-07-21T18:12:02 < Ecco> Tectu: Indeed, Freescale also offers cheap M0+
2015-07-21T18:12:38 < Ecco> I have no production experience with MCUs
2015-07-21T18:12:43 < Ecco> I can read a datasheet
2015-07-21T18:12:51 < karlp> there's not a _lot_ of differences between m0 and m0+, some things that might matter for bootloaders, but not much else
2015-07-21T18:12:54 < Ecco> and apparently all those device seem pretty similar on the outside
2015-07-21T18:13:06 < karlp> take all the power measurements with a grain of salt
2015-07-21T18:13:20 < Ecco> karlp: Indeed. ARM's website says the difference is essentially the power consumpion
2015-07-21T18:13:21 < karlp> at least the claims, setup something like what your final system will be and actually test it.
2015-07-21T18:13:37 < jpa-> Ecco: seems the atmel part doesn't even have DMA
2015-07-21T18:13:43 < Ecco> jpa-: Indeed it doesn't
2015-07-21T18:13:45 < karlp> and the power consumption of the core is quite possibly not even relevant to your system consumption
2015-07-21T18:14:18 < Ecco> karlp: I think in my case it is. But you're right, in general chances are it's not :)
2015-07-21T18:14:42 < karlp> Ecco: you'd be surpised how easy it is to miss things that are eating power
2015-07-21T18:14:53 < jpa-> implementation technology might matter a lot more than the core on the chip
2015-07-21T18:14:58 < karlp> Ecco: also, even on the MCU, the cortex core is just one portion
2015-07-21T18:15:03 < Ecco> Indeed
2015-07-21T18:15:05 < karlp> the peripherals use power too
2015-07-21T18:15:19 < Ecco> Ok, so I think you guys have the expertise that I'm lacking
2015-07-21T18:15:30 < jpa-> but i'm not so sure why you'd want a cortex-m0 with a lot of flash anyway
2015-07-21T18:15:35 < Ecco> so should I stick to ST or are the other competitors worse looking at?
2015-07-21T18:16:03 < jpa-> well, if you really need to optimize, sure, they can be better for particular tasks
2015-07-21T18:16:19 < jpa-> but stm32 seems to work well and it is not total crap like e.g. LPC1768
2015-07-21T18:16:31 < Ecco> jpa-: Good question. I expect my firmware to be rather large, but I don't need a lot of processing power, so M0 seemed like a good fit. Also I'm tight on battery
2015-07-21T18:16:39 < jpa-> it is easy to accidentally select a totally stupid processor because it is not always obvious from datasheet
2015-07-21T18:16:40 < Ecco> Gotcha
2015-07-21T18:17:57 < jpa-> if you have any divisions, you'll probably win on battery by using Cortex-M3 and clocking it down

2015-07-21T18:18:41 < Ecco> Interesting
2015-07-21T18:18:57 < jpa-> but i'd expect you would atleast make a proto way before you are that worried about minute differences in prices
2015-07-21T18:19:03 < Ecco> Indeed
2015-07-21T18:19:08 < Ecco> Actually that's exactly where I'm at
2015-07-21T18:19:16 < Ecco> I'm picking an MCU for a prototype
2015-07-21T18:19:53 < Ecco> So far I've been working w/ STM32F4. Very nice device, but a lot more expensive than STM32F0 for example
2015-07-21T18:20:03 < Ecco> And I don't think I need the extra power/features
2015-07-21T18:24:07 < zyp> how do you get a large firmware that doesn't use much cpu time? lots of .rodata? :p
2015-07-21T18:25:36 < Ecco> zyp: Not necessarily :)
2015-07-21T18:25:47 < Ecco> You can have a complex program that doesn't need to be ran fast
2015-07-21T18:25:51 < zyp> well, I'm genuinely curious
2015-07-21T18:26:08 < Ecco> A videogame for example
2015-07-21T18:26:13 < Ecco> Indeed, there's a lot of rodata
2015-07-21T18:26:21 < Ecco> but the executable portion can be large too
2015-07-21T18:28:20 < zyp> hmm, different scenes, I guess, so only part of it gets executed at a time
2015-07-21T18:28:25 < zyp> makes sense
2015-07-21T18:29:57 < zyp> so far all my stuff tend to be <10k, but then I'm mainly looping stuff that happens a couple thousand times every second or so

2015-07-21T18:52:42 < PointerToNull> I've google it but I haven't found any oper source projects..
2015-07-21T18:53:04 < zyp> hmm, doesn't the F4-disco only have accelerometer?
2015-07-21T18:53:26 < zyp> IIRC the F3-disco have a combo gyro/accel chip
2015-07-21T18:53:30 < PointerToNull> zyp, yes I think we need also gyro
2015-07-21T18:53:36 < zyp> yes
2015-07-21T18:53:59 < zyp> gyro is the most important chip, since it's responsible for primary stabilization

2015-07-21T18:54:52 < PointerToNull> Yeah right.. I have an STM32F4 maybe I can interface a gyro via i2c
2015-07-21T18:54:56 < Ecco> Both of those are second-order sensors though
2015-07-21T18:55:07 < Ecco> so you'll accumulate errors while integrating
2015-07-21T18:55:25 < PointerToNull> Or you think is better an F3-disco?
2015-07-21T18:55:30 < Tectu> PointerToNull, is this some proof-of-concept thing or what is your motiviation not to build a custom board?
2015-07-21T18:56:29 < Tectu> PointerToNull, I am sure there are plenty of people who use some IMU hooked up to an F4 via SPI to fly a quad.

2015-07-21T19:05:13 < zyp> Ecco, that's not really true
2015-07-21T19:05:42 < PointerToNull> Laurenceb is it an open source project?
2015-07-21T19:05:52 < PointerToNull> Would be great start from there
2015-07-21T19:05:53 < Laurenceb> yes, #taulabs
2015-07-21T19:08:08 < zyp> Ecco, the gyro output is angular rate, which is used to stabilize the angular rate of the quad, so there's no integration involved there
2015-07-21T19:08:56 < _Sync_> all those shitty mems gyros
2015-07-21T19:08:57 < zyp> of course, a quad with only rate stabilization will not be able to keep horizontal on its own
2015-07-21T19:09:00 < _Sync_> needs fiber optic gyros
2015-07-21T19:10:13 < Tectu> fiber optic gyros? Wut? gotta google that
2015-07-21T19:10:31 < zyp> for secondary stabilization, the gyro is integrated with drift corrected by the gravity vector measured by the accelerometer
2015-07-21T19:11:08 < zyp> gravitational acceleration is the direct output of an accelerometer on an otherwise not accelerating vehicle, so there's no accumulated error here either
2015-07-21T19:11:18 < _Sync_> Tectu: they are the shi

2015-07-22T00:37:04 < Tectu> wtf ST, please explain this:  in I2Cv2 (the one used by F3, F7 and others) there are dedicated registers for sending and receiving data (TXDR and RXDR). Now, there is a bit for each of those in the status reg that tells you whether it is empy or not. For RX they use RXNE (receive data register is NOT empty) and for TX they use TXE (transmit data register empty)
2015-07-22T00:37:14 < Tectu> why inverting the logic there?

2015-07-22T03:18:48 < kakimir_> nsfw!
2015-07-22T03:18:57 < dongs> unfunny
2015-07-22T03:19:43 < Tectu> dongs, surface pro 3 does not look that bad. Any ideas on the battery life? for how long have you used one?
2015-07-22T03:21:00 < dongs> er, probably not long enough to run out. im usually near some outlet etc so i dont care much for that.
2015-07-22T03:21:19 < _Sync_> Tectu: it lasts suprisingly long
2015-07-22T03:21:40 < _Sync_> but be aware, the wandows 10 bootloader is an asshole
2015-07-22T03:22:12 < Tectu> _Sync_, do you have one personally?
2015-07-22T03:22:42 < _Sync_> no, but I have used one
2015-07-22T03:23:05 < Tectu> _Sync_, I currently have a lenovo thinkpad yoga business ultrabook. But the first version. It has no sane trackpad buttons and the display is SHIT (has serious ghost issues)
2015-07-22T03:23:21 < Tectu> lenovo is aware of the latter. the panel has a fabrication issue but they refuse to replace it
2015-07-22T03:23:38 < Tectu> and the surface 3 pro looked like a consideration worth taking
2015-07-22T03:23:38 < _Sync_> oh, I have one of those and the display is not too bad
2015-07-22T03:23:56 < _Sync_> well, the keyboard is shit for serious work
2015-07-22T03:23:57 < Tectu> _Sync_, you got the first Thinkpad Yoga?
2015-07-22T03:24:07 < Tectu> indeed
2015-07-22T03:24:22 < _Sync_> I think I do, I got one from $workplace
2015-07-22T03:24:27 < Tectu> for how long do you have it? I have it 1.5 years now and the display issue is getting way worse over time. Can barely watch a movie on that thing
2015-07-22T03:24:49 < _Sync_> yeah about 1.5 years
2015-07-22T03:24:59 < Tectu> the only thing I seriously love about this thing is the OneLink dock.
2015-07-22T03:25:12 < Tectu> seriously gonna miss that. But newer lenovo models dont come with that for some reason
2015-07-22T03:25:16 < Tectu> most of them dont, at least.

2015-07-22T03:28:47 < Tectu> the OneLink dock made this machine become my main workstation

2015-07-22T03:30:09 < _Sync_> I have to drag the dock around with me for it to be any useful
2015-07-22T03:30:24 < _Sync_> which mostly negates the ultrabook factor for me
2015-07-22T03:30:38 < Tectu> i use the ultrabook factor while not being at home and the dock factor while being at home
2015-07-22T03:30:51 < Tectu> the dock is taped to my desks underside
2015-07-22T03:31:00 < Tectu> get home, one cable, all done

2015-07-22T03:34:07 < _Sync_> it does not perform well enough for me to replace my workstation
2015-07-22T03:34:22 < _Sync_> I think I used it for a few weeks and now it is in a drawer
2015-07-22T03:34:51 < Tectu> just curious... are you sure that you got the true OneLink Pro dock and not the same one that just uses USB 3.0 crap to interface it?
2015-07-22T03:36:45 < _Sync_> pretty much
2015-07-22T03:37:02 < Tectu> never tried linux with it, tho.
2015-07-22T03:38:15 < _Sync_> interestingly it just works

2015-07-22T03:49:44 < Tectu> cu!
2015-07-22T03:53:01 < karlp> Tectu: txe/rxne isn't just i2c.  have you never used a uart before?
2015-07-22T03:53:11 < karlp> it's so that the "positive" bit set case is the one your normally care about

2015-07-22T03:53:28 < Tectu> karlp, I doubt that uart uses the txe/rxne bits inside the i2c ISR register?
2015-07-22T03:53:43 < karlp> no, but it also has txe and rxne bits for the same purpose
2015-07-22T03:53:56 < karlp> you were complaining abotu the "inconsistent" polarity..
2015-07-22T03:53:58 < upgrdman> anyone here use eclipse cdt? is it possible to find where a #define is used in a project? like the equivalent of a "call hierarchy" ... since that doesn't work with #define's
2015-07-22T03:54:10 < Tectu> karlp, makes sense. thanks for the follow up!
2015-07-22T03:54:18 < karlp> I was saying it's actually "consistent" with tradition and other periphs, even if it doesn't fit your swiss world view :)
2015-07-22T03:55:11 < karlp> think about what it woudl mean if the bit was "tx is full", what would you interrupt on then, the bit going clear? that would be truly fucked :)
2015-07-22T03:55:18 < Tectu> <karlp> it's so that the "positive" bit set case is the one your normally care about   <---- totally fits my world view ;)
2015-07-22T03:56:27 < karlp> good good
2015-07-22T03:57:25 < Tectu> karlp, how well do you know the I2Cv2? I am struggling with the fact that the TXIS is always cleared.
2015-07-22T03:58:12 < Tectu> karlp, I set up my i2c for master transmit, it sends the address, gets the ACK from the slave (I see that on the scope) but it does not send any further data. Just sits there in the waiting for TXIS going high loop.
2015-07-22T03:58:28 < Tectu> karlp, I set the NBYTES to 1. in order to send one byte.
2015-07-22T03:58:43 < karlp> if I had time and experience with the newer i2c periph, I'm not so mean that I would have avoided helping you :)
2015-07-22T03:58:57 < dongs> i am
2015-07-22T03:59:05 < Tectu> karlp, thanks ;)

2015-07-22T06:03:49 < dongs> We are currently awaiting compliance certificates before we can begin sending the orders.
2015-07-22T06:03:52 < dongs> Kickstarter orders will begin to be shipped as of 27th July and we expect all Kickstarter rewards and flyzano pre-orders to be delivered by the end of September.
2015-07-22T06:03:56 < dongs> The UK and Europe will be the first locations to receive their ZANO.s so I would anticipate you will receive your order in August.
2015-07-22T06:04:32 < dongs> they're going to ship 12000 useless things that dont work anywhere near as advertised, lol.
2015-07-22T06:04:38 < dongs> and they're already refusing refunds
2015-07-22T06:04:43 < dongs> because the order has been "palced"
2015-07-22T06:04:45 < dongs> "placed", too
2015-07-22T06:05:15 < Roklobsta> well, august will be interesting
2015-07-22T06:05:51 < Roklobsta> awaiting complaince == buying time
2015-07-22T06:06:09 < dongs> they dont need compliance to show it doing something outside
2015-07-22T06:06:13 < Roklobsta> no
2015-07-22T06:06:45 < Roklobsta> that said compliance should be a really quick thing to get done in europe.

2015-07-22T10:00:28 < PaulFertser> Also, the ST code has a major deficiency: if the target rebooted during copy from one page to another, and then rebooted again and again and again, the target page eventually fills and the whole eeprom emulation framework stops working till you erase all the flash.
2015-07-22T10:03:36 < ReadError> I was thinking of not using their page stuff and just using FLASH_ProgramWord to copy a struct

2015-07-22T17:39:57 < dongs> yea im there now
2015-07-22T17:40:01 < dongs> whats diff from 2560
2015-07-22T17:40:11 < dongs> ohh you can get it in QFN?
2015-07-22T17:40:22 < dongs> lol $10/ea
2015-07-22T17:40:23 < dongs> fuck
2015-07-22T17:40:24 < dongs> me
2015-07-22T17:42:12 < Laurenceb> why does that exist
2015-07-22T17:42:53 < Tectu> TempleOS
2015-07-22T17:43:18 < Laurenceb> templeos should have its own irc
2015-07-22T17:43:29 < Laurenceb> HOLY SHIt
2015-07-22T17:43:33 < Laurenceb> it does
2015-07-22T17:43:47 < Laurenceb>  Topic for #templeos is: The OS as decreed by God | "God said 640x480 16 color was a covenant like circumcision."
2015-07-22T17:44:05 < jpa-> i wonder if that chip grinding is some kind of cargo cult.. "i saw a device where this was done, i have to do it too!"
2015-07-22T17:44:23 < Laurenceb> Topic for #templeos set by TheRealJohnGalt
2015-07-22T17:44:25 < Laurenceb> lulz
2015-07-22T17:44:28 < Tectu> jpa-, some people might think that it is some pro sign
2015-07-22T17:44:32 < jpa-> a lot of chinese devices seem to do that.. even clones of other devices, so not like they have any original IP to steals
2015-07-22T17:45:09 < Laurenceb> i spot jumper wires
2015-07-22T17:45:16 < Tectu> jpa-, saw it in some high-grade gear too
2015-07-22T17:45:30 < jpa-> Tectu: yes, but there it makes sense
2015-07-22T17:45:31 < BrainDamage> it's a mark of originality, having your chip delabeled
2015-07-22T17:46:54 < Laurenceb> heh there is someone from uni of waterloo
2015-07-22T17:47:00 < Laurenceb> in #templeos
2015-07-22T17:47:07 < englishman> theres someone in here too
2015-07-22T17:47:13 < karlp> mark of originality is getting them relabelled
2015-07-22T17:47:24 < karlp> fuck delablleing,
2015-07-22T17:48:26 < karlp> that sduino thing is cute :)
2015-07-22T17:51:08 < Tectu> somebody translate that please (the second part of it)  ´I had some problems with compiling under Windows. Now I need some time out and lately I'm going to return.´

2015-07-22T17:51:42 < dongs> on the batshitinsane scale?
2015-07-22T17:51:58 < jpa-> nope
2015-07-22T17:52:21 < jpa-> reactos is only mildly pointless, i can't see much insanity with it
2015-07-22T17:52:28 < BrainDamage> reactos is reimplementing windows api and abi in open sores
2015-07-22T17:52:46 < Tectu> reactos is still a thing?
2015-07-22T17:52:49 < dongs> which is pretty nuts
2015-07-22T17:52:54 < dongs> and pointless
2015-07-22T17:53:28 < BrainDamage> it's not pointless if you want a feature in the kernel that's not available currently
2015-07-22T17:53:30 < jpa-> well wine is somewhat similar and it is definitely not pointless

2015-07-22T21:54:49  * Laurenceb__ has 41µA leakage on his datalogger with ltc1844 regs
2015-07-22T21:55:18 < englishman> bench current in videos is like 450mA

2015-07-22T21:56:15 < Laurenceb__> my lipo cells seem to have some leakage from somewhere else...

2015-07-22T21:56:46 < Laurenceb__> I'm getting ~6months life with 130µA leakage from 1.3Ah cells
2015-07-22T21:56:49 < Laurenceb__> thats not right
2015-07-22T21:57:05 < _Sync_> do it like dewalt and use no protection
2015-07-22T21:57:24 < qyx_> why lipo?
2015-07-22T21:57:54 < qyx_> i mean wouldn't it be better to use some industrial lisocl2 primary cells for such applications?
2015-07-22T21:58:58 < Laurenceb__> no, because when its running it draws 35mA

2015-07-22T22:05:46 < Laurenceb__> yes, i use octave a lot
2015-07-22T22:05:58 < Laurenceb__> never used scipy
2015-07-22T22:06:11 < BrainDamage> check sympy too, for symbolic calculations
2015-07-22T22:06:15 < Laurenceb__> numpy is usually faster, and can generate compiled code more easily
2015-07-22T22:06:16 < emeb> well, it's python so it looks different
2015-07-22T22:06:28 < Laurenceb__> but it always ends up being more complex
2015-07-22T22:06:34 < emeb> yeah
2015-07-22T22:06:40 < emeb> more typing it seems

2015-07-22T22:06:59 < Laurenceb__> no way you could do it as simply in python
2015-07-22T22:07:32 < Laurenceb__> numpy always seems to end up a bit more complex
2015-07-22T22:07:47 < emeb> matrix ops not as clean?
2015-07-22T22:07:53 < Laurenceb__> no imo
2015-07-22T22:08:09 < emeb> that's what it seems like to me as well
2015-07-22T22:08:13 < Laurenceb__> the plotting is also more complex if you want a simple plot
2015-07-22T22:08:17 < emeb> the iterators aren't as natural
2015-07-22T22:08:28 < Laurenceb__> but imo its much nicer for plotting if you want complex well defined plots
2015-07-22T22:08:33 < emeb> yeah - plotting seems similarly verbose.
2015-07-22T22:08:50 < Laurenceb__> complex plots in matlab can be a major headache
2015-07-22T22:09:09 < emeb> I have a client who always wants tweaks to the plots
2015-07-22T22:09:13 < Laurenceb__> I've had to resort to csv export and gnuplot
2015-07-22T22:09:13 < emeb> "make the font bigger"
2015-07-22T22:09:20 < emeb> "make the lines fatter"
2015-07-22T22:09:31 < Laurenceb__> also bash/awk scripts to fix eps export
2015-07-22T22:09:32 < emeb> It's possible in matlab, but takes a lot of effort
2015-07-22T22:09:50 < Laurenceb__> ive used awk to fix lines and fonts before
2015-07-22T22:10:05 < emeb> ugh
2015-07-22T22:10:24 < Laurenceb__> eps is pretty hand editable
2015-07-22T22:10:40 < emeb> it's just forth. :)
2015-07-22T22:11:24 < emeb> Well, I'm not going to abandon matlab - spent too much on it over the years. OTOH, it's worth keeping up with what the kids these days think is the hotness.
2015-07-22T22:11:56 < emeb> an apparently at the big SW shops matlab is considered old-n-busted.
2015-07-22T22:12:52 < emeb> like don't put that on your resume - it's like claiming knowledge of cobol or something.
2015-07-22T22:12:59 < Laurenceb__> its used for _everything_ at my uni
2015-07-22T22:13:04 < Laurenceb__> hehe
2015-07-22T22:13:40 < emeb> yeah - saw a rant about that the other day.
2015-07-22T22:34:17 < Taxman> and what about octave? Is anyone using this?
2015-07-22T22:34:34 < Laurenceb__> i use it
2015-07-22T22:35:24 < Taxman> so it seems to be useable, i assume it has not all the modules mathlab offers
2015-07-22T22:37:23 < BrainDamage> not by a long shot

2015-07-22T22:50:25 < emeb> I use octave on machines that aren't licensed for matlab
2015-07-22T22:50:35 < emeb> it's *mostly* compatible.
2015-07-22T22:50:43 < emeb> some more advanced stuff it doesn't do
2015-07-22T22:50:50 < krakapwa_> do you have a gui for octave?
2015-07-22T22:50:52 < emeb> and some syntax is slightly different
2015-07-22T22:50:59 < emeb> no
2015-07-22T22:51:02 < emeb> just cmd line
2015-07-22T22:51:04 < BrainDamage> octave 4 has gui
2015-07-22T22:51:20 < krakapwa_> how do you debug without gui?
2015-07-22T22:51:34 < BrainDamage> wut
2015-07-22T22:51:46 < emeb> it's an interpreter. just run, see the errors
2015-07-22T22:52:17 < emeb> immediate mode is handy - just type in a line of valid syntax for instant answer.
2015-07-22T22:52:24 < krakapwa_> i got quickly used to debug mode in matlab tho
2015-07-22T22:52:33 < emeb> yeah - that's nice.
2015-07-22T22:52:49 < emeb> dunno if there's equivalent in octave. Hasn't been a big issue.

2015-07-23T04:14:10 < jadew> the problem is that the mouse stops abrubtly where the ring finger should rest
2015-07-23T04:14:51 < jadew> so instead of resting, it's holding the mouse, which is really the job of the pinky

2015-07-23T04:26:04 < dongs> its already on keyboard
2015-07-23T04:26:07 < dongs> why would I need to reach for the mouse
2015-07-23T04:26:16 < jadew> how do you browse?
2015-07-23T04:26:17 < dongs> do you click into a window to a ctivate it too?
2015-07-23T04:26:28 < jadew> no, but I like the wheel to scroll
2015-07-23T04:26:37 < jadew> and click on links, instead of hitting tab
2015-07-23T04:27:00 < jadew> I ordered this a few hours ago: http://www.ebay.co.uk/itm/121702195613
2015-07-23T04:27:07 < jadew> hopefully I'll get used to the layout
2015-07-23T04:27:48 < jadew> I remember that when I got used to code from the laptop and moved back to the desktop I really missed the trackpoint

2015-07-23T04:28:46 < dongs> ew bluetooth kbd
2015-07-23T04:28:48 < dongs> much lag
2015-07-23T04:28:50 < dongs> enjoy it.
2015-07-23T04:29:03 < jadew> I had one before, it didn't suck
2015-07-23T04:29:08 < jadew> not like that one, but a bluetooth keyboard
2015-07-23T04:29:22 < dongs> i think im gonna go back to sleep

2015-07-23T04:32:49 < jadew> logitech mices are so expensive
2015-07-23T04:33:13 < kakimir_> i googled some day of inexpensice mouses
2015-07-23T04:33:39 < kakimir_> there was alternative
2015-07-23T04:33:47 < kakimir_> *an
2015-07-23T04:34:03 < kakimir_> for high priced logitechs
2015-07-23T04:35:09 < jadew> of course there are, logitech cater for snobs
2015-07-23T04:35:21 < jadew> their shit is the same with everyone elses
2015-07-23T04:35:35 < kakimir_> why are mouses pieces of crappy plastic
2015-07-23T04:35:43 < kakimir_> I want titanium
2015-07-23T04:36:11 < jadew> I'm sure that if IBM still cared about the consumer market they would have made one
2015-07-23T04:36:30 < jadew> some of their thinkpads had titanium cases
2015-07-23T04:36:50 < kakimir_> consumer market is shit down the throats for lowest prices
2015-07-23T04:36:57 < jadew> yeah

2015-07-23T04:41:06 < jadew> dongs, I just remembered, I had similar issues with a wireless hama mouse, had to put the usb dongle about 40 cm from the mouse
2015-07-23T04:44:38 < kakimir_> if receiver doesn't have desktop stand - you are fucked
2015-07-23T04:48:45 < jadew> sad as it is, it appears a logitech mouse comes the closest to what I'm looking for :/
2015-07-23T04:49:01 < kakimir_> http://www.engadget.com/products/logitech/mx/1000/
2015-07-23T04:49:07 < kakimir_> still operating
2015-07-23T04:49:26 < kakimir_> good buy back then
2015-07-23T04:49:37 < kakimir_> replaced lipo
2015-07-23T04:49:53 < jadew> $270 ??!
2015-07-23T04:50:03 < kakimir_> collection item.
2015-07-23T04:50:08 < jadew> come on...
2015-07-23T04:50:28 < kakimir_> it's 2005 mouse
2015-07-23T04:50:31 < jadew> you can build one yourself on that budget
2015-07-23T04:51:01 < jadew> and make it have the exact shape you want it to have
2015-07-23T04:51:24 < jadew> a mouse is not worth more than $40
2015-07-23T04:51:38 < jadew> well, it's not worth more than $15
2015-07-23T04:51:47 < jadew> but you pay $40 because you really like that one
2015-07-23T04:52:48 < jadew> I fell in the logitech trap too once
2015-07-23T04:52:53 < jadew> with a keyboard
2015-07-23T04:53:10 < jadew> paid ~$250 for it and it was a POS
2015-07-23T04:53:25 < kakimir_> never had logitech keyboard
2015-07-23T04:53:50 < jadew> I had that dinovo edge or something
2015-07-23T04:54:07 < jadew> everything about it was retarded
2015-07-23T04:54:15 < jadew> you could only charge it on a stand
2015-07-23T04:54:25 < jadew> so if the battery was low, you couldn't use it
2015-07-23T04:55:01 < kakimir_> looks cool
2015-07-23T04:55:08 < kakimir_> but looks expensives
2015-07-23T04:55:22  * jadew has a proper keyboard: https://elitekeyboards.com/products.php?sub=leopold,fullsize&pid=fc500rtab
2015-07-23T04:55:54 < jadew> full travel mechanical switches
2015-07-23T04:56:02 < kakimir_> just paid for tenkeypad +$60
2015-07-23T04:56:06 < jadew> and silent
2015-07-23T04:56:18 < jadew> but still with a bit of tactile feedback
2015-07-23T04:56:57 < kakimir_> mechanical. completes my set
2015-07-23T04:57:44 < jadew> I only use the numeric pad to control volume and start the calculator
2015-07-23T04:57:50 < jadew> (I remapped those keys)
2015-07-23T04:58:33 < jadew> I'm really curious how the lenovo keyboard will feel like
2015-07-23T04:58:56 < jadew> I sure hope they have the same mechanism they use on the good laptops
2015-07-23T04:59:11 < jadew> R2COM, is it not rubbery?
2015-07-23T04:59:23 < jadew> rubbery
2015-07-23T04:59:25 < jadew> with u
2015-07-23T04:59:46 < jadew> the rubber button feel you get on cheap keyboards
2015-07-23T04:59:59 < kakimir_> https://farm9.staticflickr.com/8437/7848439596_e204d54fec_b.jpg
2015-07-23T05:00:08 < jadew> that's good
2015-07-23T05:00:27 < kakimir_> imagine ton of crap on that keyboard and you got my set
2015-07-23T05:00:33 < jadew> all slim keyboards use rubber contacts and only a few of them manage to give good tactile feedback
2015-07-23T05:04:24 < kakimir_> I think I'm going to get a siphon
2015-07-23T05:04:35 < kakimir_> *syphon
2015-07-23T05:04:35 < jadew> it's rather uncommon to have any sort of UI + direct3d
2015-07-23T05:04:50 < jadew> there are only a handful of application that need that
2015-07-23T05:04:57 < jadew> *applications
2015-07-23T05:06:02 < jadew> yeah, just think about how many apps do that
2015-07-23T05:06:15 < jadew> but even so, I don't see why it wouldn't be possible
2015-07-23T05:06:19 < jadew> should work just fine
2015-07-23T05:07:46 < kakimir_> is there anything I should concern when buying a syphon?
2015-07-23T05:08:07 < jadew> of course, there are lots of applications that use it for other stuff, but it's still not that common
2015-07-23T05:09:17 < jadew> R2COM, why do you ask anyway?
2015-07-23T05:09:35 < jadew> should work
2015-07-23T05:10:22 < jadew> you can create a window yourself that handles the same events
2015-07-23T05:10:25 < jadew> in MFC
2015-07-23T05:10:41 < jadew> or WTL for that matter
2015-07-23T05:10:59 < jadew> WTL?
2015-07-23T05:11:10 < jadew> works fine for me
2015-07-23T05:11:18 < jadew> you unzip and run setup.js
2015-07-23T05:12:08 < jadew> that's true
2015-07-23T05:12:37 < jadew> too bad it's not getting more attention, it's a great library
2015-07-23T05:13:33 < jadew> that's true too
2015-07-23T05:14:39 < jadew> they bought a bunch of controls from some other company
2015-07-23T05:14:50 < jadew> that's pretty much the latest update MFC got too
2015-07-23T05:14:54 < jadew> that's back in 2008 I think
2015-07-23T05:15:04 < jadew> the bugs that those libraries had, are still there
2015-07-23T05:15:39 < jadew> I don't think MS cares about C++ as it used to
2015-07-23T05:15:46 < jadew> they care more about getting people into c#
2015-07-23T05:16:16 < jadew> R2COM, no, you'll have to search for it, but it should be fairly easy to roll your own
2015-07-23T05:16:46 < jadew> well, something basic
2015-07-23T05:17:26 < jadew> I haven't done any c# in a long time
2015-07-23T05:18:47 < jadew> it's not, unless you're looking for a c# job
2015-07-23T05:18:52 < jadew> of course

2015-07-23T05:22:45 < jadew> lmfao, found a mouse that looks exactly like the MS mouse I loved

2015-07-23T05:30:01 < jadew> my wife got me the RAT-7 when it came out and I really loved the pinky support
2015-07-23T05:30:15 < jadew> it was a very comfortable mouse
2015-07-23T05:30:29 < jadew> kinda looking for something with that built in
2015-07-23T05:34:32 < jadew> it looks ok
2015-07-23T05:34:47 < jadew> the most important part is what's on the pinky side
2015-07-23T05:35:09 < jadew> the ones that have the wall recessed inside the mouse suck
2015-07-23T05:35:38 < jadew> because you'll have to put extra effort in getting your pinky or the ring finger inside there to actually get a grip
2015-07-23T05:41:43 < zyp> heh, jap news is going on about that youtube vid of the guy flying a gun on a quadrotor
2015-07-23T05:42:25 < jadew> no worries there, only the zano can aim it
2015-07-23T05:47:42 < zyp> right
2015-07-23T06:03:46 < jadew> I ended up ordering two mice http://www.emag.ro/mouse-genius-dx-6810-wireless-argintiu-g-31030110101/pd/DVBYZBBBM/
2015-07-23T06:03:47 < jadew> and http://www.emag.ro/mouse-optic-asus-wt425-1600-dpi-usb-negru-90xb0280-bmu000/pd/D30W3MBBM/
2015-07-23T06:03:52 < jadew> ~ $25 total
2015-07-23T06:04:57 < jadew> we'll see about that
2015-07-23T06:05:25 < jadew> I get that for free
2015-07-23T06:05:58 < jadew> of course not
2015-07-23T06:07:55 < jadew> I might get some tomorrow, as gratitude

2015-07-23T09:52:54 < emeb_mac> waste of time, money and power considering the Zynq chip costs 10x what the Propeller costs and you're leaving most of it disabled.

2015-07-23T10:45:48 < dongs> where it says
2015-07-23T10:45:52 < dongs> PC13,14,15 are low-current pins
2015-07-23T10:45:56 < dongs> and should never drive or sink leds
2015-07-23T10:46:10 < dongs> and there's some more restrictions on F4 for those pins afaik
2015-07-23T10:46:14 < dongs> you done fucked up

2015-07-23T10:48:42 < dongs> haha
2015-07-23T10:48:51 < dongs> ^DEMOSS^: yes, i realize the pin might be broken out on the board
2015-07-23T10:48:55 < dongs> the point is, you should not be connecting a led to it
2015-07-23T10:49:03 < dongs> use any of the other ~30something free pins.
2015-07-23T10:49:08 < GargantuaSauce_> what's a few mA between friends

2015-07-23T12:10:22 < PaulFertser> Systematic approach to learning usually pays off. Doing easy things without understanding usally gives too little. Your choice.
2015-07-23T12:12:06 < PaulFertser> BTW, the compiler will optimise away that for() cycle in the delay function if optimisations are not disabled. Needs volatile keyword.

2015-07-23T17:16:46 < Strogg> either it was the order that I was initializing the gpio, timer, pwm, or I was calling the wrong TIM_OC*INIT() function

2015-07-23T17:19:16 < karlp> are those "significant" or just "detectable" ?
2015-07-23T17:19:34 < Laurenceb> I dunno
2015-07-23T17:19:41 < Laurenceb> need to do a statistical test on it
2015-07-23T17:21:30 < Laurenceb> might be useful for road monitoring

2015-07-23T17:29:49 < Strogg> allllright.  so.. I've found some code and I've gotten it to work.. it setups a PWM output on PB9 TIM4.  My period is 110us, which means my frequency is about 9kHz.
2015-07-23T17:30:33 < Strogg> I have a prescaler of 0, a TIM_period of 8000 and a TIM_pulse of 4000, but when I try to reduce those numbers, it stops working.
2015-07-23T17:30:45 < Strogg> is 9kHz the best I can get for a PWM waveform?
2015-07-23T17:31:04 < Fleck> ofc not :D
2015-07-23T17:31:06 < dongs> err no
2015-07-23T17:31:25 < dongs> you can do it at up to 1/2 your AHB/whatever ffrequency, and higher on some parts.
2015-07-23T17:31:41 < Strogg> ok.. I figured as much.  so where am I going wrong?  am I using the wrong PWM mode?
2015-07-23T17:32:03 < Fleck> we can't answer that :D

2015-07-23T17:32:33 < qyx_> Strogg: 72000000/8000 = 9kHz
2015-07-23T17:33:09 < Strogg> right..  but why can't I reduce the 8000?  If I do that, my output frequency "goes away"

2015-07-23T20:39:54 < kakimir_> hmm blocksize
2015-07-23T20:40:22 < kakimir_> it says only and only if your harddrive is 4kb blocksize you can use 4kb
2015-07-23T20:40:31 < kakimir_> I have always used it without thinking
2015-07-23T20:40:42 < Strogg> Is it correct to say Alternate Function 0 (AF0) is always selected on your GPIO when you first power up your micro.
2015-07-23T20:41:03 < Rickta59> it was just a test to see if it would actually create a useable link karlp
2015-07-23T20:41:17 < GargantuaSauce> Strogg: just look at the reset value of the relevant register in the reference manual
2015-07-23T20:41:33 < Strogg> GargantuaSauce: hrmmm good idea
2015-07-23T20:44:39 < kakimir_> okay my drives are 4k bs

2015-07-23T23:14:51 < kakimir_> why is pragma once better than
2015-07-23T23:15:20 < kakimir_> definition based include guard?
2015-07-23T23:15:23 < gxti> less boilerplate and harder to screw up
2015-07-23T23:16:09 < kakimir_> you mean more boilerplate?
2015-07-23T23:16:49 < kakimir_> In computer programming, boilerplate code or boilerplate is the sections of code that have to be included in many places with little or no alteration.
2015-07-23T23:17:22 < gxti> ifdef guard requires 3 lines per file, pragma once is  1 line
2015-07-23T23:17:46 < gxti> and you have to have a uniquely named macro for the ifdef guard across all headers you'll ever include
2015-07-23T23:18:36 < kakimir_> yes
2015-07-23T23:19:03 < kakimir_> still hard to make macros that have _H_ in end of name?
2015-07-23T23:19:44 < kakimir_> yes it's clean
2015-07-23T23:20:04 < gxti> i didn't say it was hard, i said it was hardER
2015-07-23T23:20:10 < kakimir_> when you have renamed files and still have some define with old name
2015-07-23T23:21:28 < kakimir_> or endif comment with old macro name
2015-07-23T23:21:31 < kakimir_> just dirty

2015-07-24T00:30:14 < Laurenceb__> lulz my weird friend from school has pulled a fritzl
2015-07-24T00:31:02 < Laurenceb__> he lives in his parents basement, they wonders why he was always carrying baby stuff down there, he said it was for selling on ebay
2015-07-24T00:31:42 < Laurenceb__> turns out he had girlfriend and baby living down there for 6 months
2015-07-24T00:31:49 < qyx_> lol
2015-07-24T00:32:24 < qyx_> Laurenceb__: what samplerate are you using on the loggers?
2015-07-24T00:32:38 < Laurenceb__> guess he only got to first generation, fritzl still wins
2015-07-24T00:32:58 < Laurenceb__> depends on the sensor
2015-07-24T00:33:03 < Laurenceb__> there ublox7 at 5hz
2015-07-24T00:33:12 < qyx_> no, i mean on accels
2015-07-24T00:33:14 < Laurenceb__> then clip on headband IMU
2015-07-24T00:33:27 < Laurenceb__> at 1.6khz accel and 800hz gyro, with 150hz magno
2015-07-24T00:33:35 < Laurenceb__> then everything else at 100hz
2015-07-24T00:33:41 < Laurenceb__> chassis and seat IMUs
2015-07-24T00:34:13 < qyx_> uhm, multiple 9dof imus per car?
2015-07-24T00:34:23 < Laurenceb__> then some temperature sensors and IR temp sensors, and calibrated off the shelf dBA mic module
2015-07-24T00:34:25 < Laurenceb__> yup
2015-07-24T00:34:39 < Lux> Laurenceb__: what accel sensor even outputs 1.6khz ?
2015-07-24T00:34:47 < Laurenceb__> lots of ST stuff
2015-07-24T00:34:59 < qyx_> yep, i used one of them
2015-07-24T00:35:13 < Lux> right, never used that stuff
2015-07-24T00:35:15 < Laurenceb__> i was running out of i2c time
2015-07-24T00:35:30 < Laurenceb__> using two i2c busses, one dedicated to the forehead band sensor
2015-07-24T00:35:31 < Lux> iirc invensens stuff does 1khz max on acc
2015-07-24T00:35:44 < Lux> why don't you just use spi ?
2015-07-24T00:35:55 < Laurenceb__> more conductors
2015-07-24T00:36:16 < Laurenceb__> I save the data to wav files, at some point i might swap to FLAC
2015-07-24T00:36:57 < Lux> so it's not all on one pcb, but on cables
2015-07-24T00:36:59 < Laurenceb__> if the EU pays me enough
2015-07-24T00:37:03 < Laurenceb__> yeah
2015-07-24T00:37:03 < Lux> i guess that makes sense

2015-07-24T00:38:32 < Laurenceb__> I have hundreds of TB of raw data atm
2015-07-24T00:39:17 < Lux> so you need some kind of encoding to save space ?
2015-07-24T00:39:52 < Lux> i'd guess most of the sensor data won't change/fluctuate much anyway
2015-07-24T00:40:24 < Laurenceb__> yeah, I could transcode to FLAC
2015-07-24T00:40:33 < Laurenceb__> but it all needs to be processed :-/

2015-07-24T04:47:35 < kakimir_> your pitot tube can't do much
2015-07-24T04:47:56 < ReadError> not on its own
2015-07-24T04:48:05 < ReadError> thats why many use fusion of both sensor

2015-07-24T04:49:38 < kakimir_> but is there minuature sensors or should I carve one myself
2015-07-24T04:49:54 < kakimir_> maybe some wind direction sensor that comes with weather station

2015-07-24T07:58:20 < zyp> ds2, pitot measures airspeed, two non-parallel pitots give you a two-dimentional airspeed vector, of which the angle is the angle of attack
2015-07-24T07:58:42 < zyp> once you've transformed it into the right coordinate system or whatever
2015-07-24T07:58:48 < zyp> at least that's how I assume it works
2015-07-24T07:59:40 < ds2> hmmm... not being an aeronautics person...
2015-07-24T08:00:13 < ds2> let see... say I have 2 of of them 90 deg apart
2015-07-24T08:00:41 < ds2> I suppose the extremes would be right

2015-07-24T08:10:31 < GargantuaSauce> you could probably have a static pressure sensor on the top and bottom edges of the wing to measure lift also

2015-07-24T08:13:18 < zyp> yeah, but that would give you lift, not AoA
2015-07-24T08:13:48 < GargantuaSauce> oh i thought we were specifically looking for a stall sensor, misinterpreted
2015-07-24T08:14:02 < GargantuaSauce> also i realllly want to see that guy's gopro footage inside the police station
2015-07-24T08:14:10 < GargantuaSauce> cause it's gonna be funn
2015-07-24T08:14:56 < zyp> 03:46:07 < ReadError> angle doesnt matter so much as airspeed
2015-07-24T08:15:17 < zyp> AFAIK critical AoA is completely irrelevant of airspeed
2015-07-24T08:15:58 < ReadError> depends on the airframe/thrust/speed etc
2015-07-24T08:16:15 < ReadError> going by AoA alone isnt viable unless you know the characteristics
2015-07-24T08:16:49 < zyp> but as airspeed goes down, AoA required to maintain enough lift for level flight goes up, and at a certain airspeed you reach critical AoA
2015-07-24T08:16:55 < zyp> this is the stall speed
2015-07-24T08:18:08 < jpa-> IIRC it is possible to have a sensor detect when the airflow separates from the wing, so that it alerts when critical AoA is exceeded
2015-07-24T08:18:25 < jpa-> but yeah, usually you'd also want a warning before that angle is exceeded
2015-07-24T08:18:26 < zyp> yes, that's what plain stall sensors do
2015-07-24T08:18:48 < GargantuaSauce> seems to me there are passive ones that whistle when laminar flow is lost also
2015-07-24T08:18:59 < zyp> yes, most small planes seem to have those
2015-07-24T08:20:23 < zyp> https://en.wikipedia.org/wiki/Angle_of_attack «However the aircraft always stalls at the same critical angle of attack.»
2015-07-24T08:20:27 < jpa-> it's probably true that any pre-stall warning will need to be calibrated to wing characteristics, and also take flaps etc. into account
2015-07-24T08:20:39 < zyp> yes
2015-07-24T08:20:52 < zyp> flaps alters the airfoil shape, and thus the characteristics
2015-07-24T08:22:55 < zyp> «Angle of attack indicators are used by pilots for maximum performance during these maneuvers since airspeed information is only indirectly related to stall behaviour.»
2015-07-24T08:23:43 < zyp> the main reason stall speeds are a thing is because few small planes have AoA sensors
2015-07-24T08:24:37 < zyp> I guess because it's probably hard to make a mechanical calculation of AoA from two pitots
2015-07-24T08:25:31 < ds2> hard needs to be well qualified thesedays
2015-07-24T08:25:56 < ds2> hard for a cortex-m0? hard for a cortex-a9 w/OpenCL assist? etc
2015-07-24T08:26:14 < zyp> that's why I said mechanical ;)
2015-07-24T08:27:07 < GargantuaSauce> microcontrollers are mechanical too, the mechanics in question just happen to be quantum
2015-07-24T08:27:48 < zyp> haha
2015-07-24T08:28:04 < zyp> well, I think quantum mechanics qualifies as hard
2015-07-24T08:28:15 < GargantuaSauce> this is true
2015-07-24T08:30:29 < ds2> ah, read that mechanical as in the sensor is mechanical
2015-07-24T08:31:48 < zyp> oh, no, I'm thinking in the sense that a traditional airspeed instrument is mechanical
2015-07-24T08:34:37 < ds2> most sensors thesedays are still mechanical despite their size

2015-07-24T14:46:54 < qyx_> what's your Vin max?
2015-07-24T14:47:10 < qyx_> l5973d for example
2015-07-24T14:47:17 < scrts2> I've used Monolithic Power Systems
2015-07-24T14:47:44 < scrts2> http://www.monolithicpower.com/DesktopModules/DocumentManage/API/Document/getDocument?id=616
2015-07-24T14:47:51 < scrts2> afaik cheaper than LM
2015-07-24T14:48:22 < mitrax> qvx_: 24V max
2015-07-24T14:48:33 < mitrax> qyx / scrts2: thanks i'll look that up

2015-07-24T14:53:28 < dongs> MPS
2015-07-24T14:53:44 < dongs> available in china, very cheap, and up t o 32Vin
2015-07-24T14:54:24 < mitrax> dongs: ah, what price range do you get them at approximatively? for say 100pcs
2015-07-24T14:54:57 < dongs> like $.50
2015-07-24T14:56:03 < qyx_> if you wanted lower Vin, there are modules like si803 or whatever
2015-07-24T14:56:15 < dongs> also RT8293B works, but up to 24V in
2015-07-24T14:56:21 < dongs> with absmax of like 26 or 28 or so
2015-07-24T14:56:28 < dongs> pin compatible wiht MPS as well
2015-07-24T14:56:36 < dongs> er, up to23V in
2015-07-24T14:56:40 < dongs> and 26V absmax
2015-07-24T14:57:09 < dongs> RT is .88$ on digikey
2015-07-24T14:57:32 < dongs> in singles
2015-07-24T14:57:35 < dongs> and .$.58 @ 100
2015-07-24T14:57:51 < dongs> if you absolutely dont need 24V or dont care about running it slightly out of spec its a good deal
2015-07-24T14:57:59 < mitrax> wow perfect
2015-07-24T14:58:23 < karlp> mitrax: that sort of stuff is relatively on topic here actually :)
2015-07-24T14:58:54 < dongs> well, the end result is probaly powering STM32 :)

2015-07-24T16:47:47 < jpa-> dongs: if the cpu is running at 72MHz, yeah, i'd think you can manage 4MHz
2015-07-24T16:48:05 < jpa-> timer driving the clock signal on CC1 and triggering dma on CC2 for example
2015-07-24T16:49:05 < dongs> no, clock is external
2015-07-24T16:49:31 < jpa-> ah, so you need to trigger dma on external signal somehow.. i wonder if a timer could do that
2015-07-24T16:49:43 < dongs> can't it?
2015-07-24T16:49:59 < jpa-> i guess it can, if you set it to count on both rising & falling edge
2015-07-24T16:50:01 < dongs> isn't that how "any"  DMA works from GPIO?
2015-07-24T16:50:19 < dongs> i thought thats how i did it with multi uart thing but maybe i was clocking out only nad not receiving
2015-07-24T16:50:22 < jpa-> sure timer can trigger dma, but can it trigger it on each external pulse
2015-07-24T16:50:25 < dongs> yeah hm i was clocking out and setting it on timer

2015-07-24T18:33:30 < krakapwa_> greetings
2015-07-24T18:33:43 < krakapwa_> i'm looking for a solution to store data from a data logger
2015-07-24T18:33:56 < krakapwa_> something more evolved than binary
2015-07-24T18:34:15 < krakapwa_> the goal is to open it in matlab and co
2015-07-24T18:34:42 < krakapwa_> i'm looking at large amount of data (3 sensors @ 500Hz running for several hours)
2015-07-24T18:35:16 < krakapwa_> and i'd like to have it structured (date/time, sensor name, subject name, etc..)
2015-07-24T18:35:33 < dongs> sounds like you need to talk to Laurenceb
2015-07-24T18:35:41 < dongs> cuz he laready did that
2015-07-24T18:35:49 < krakapwa_> right
2015-07-24T18:35:54 < krakapwa_> he did give me a github link
2015-07-24T18:36:00 < dongs> ten go copy it
2015-07-24T18:36:09 < Tectu> dongs, remember Laurenceb syntax...  no spaces
2015-07-24T18:36:45 < dongs> innovated in layout for 3 hours, time to bed
2015-07-24T18:36:48 < krakapwa_> i just checked. It looks like plain csv
2015-07-24T18:37:11 < krakapwa_> not quite what i'm looking for since that would make huge files
2015-07-24T18:37:22 < Laurenceb> i have wav somewhere

2015-07-24T18:47:56 < Laurenceb> wav is nice as you can store number of bits, sample rate, number of channels
2015-07-24T18:48:26 < kakimir_> and you can listen it
2015-07-24T18:48:40 < kakimir_> so you want process be done in your chip or postprocess?

2015-07-24T23:40:36 < Laurenceb__> many cards are always <8ms

2015-07-24T23:42:33 < Laurenceb__> yeah my code uses some lame busy wait stuff then everything important is in interrupts
2015-07-24T23:42:33 < Lux> i have enough ram to buffer
2015-07-24T23:42:46 < Laurenceb__> tbh I usually see <1ms card wait states
2015-07-24T23:43:07 < Lux> what kind of sdcard are you using ?
2015-07-24T23:43:08 < Laurenceb__> and its writing every 180ms or so
2015-07-24T23:43:16 < Laurenceb__> sandisk µSD
2015-07-24T23:43:18 < Laurenceb__> 4GB
2015-07-24T23:43:36 < Laurenceb__> so its <<1% overhead
2015-07-24T23:43:51 < Lux> that's pretty good
2015-07-24T23:44:11 < Laurenceb__> optimally you might use an interrupt driven state machine
2015-07-24T23:44:20 < Laurenceb__> you could probably shoehorn that into the fatfs drivers
2015-07-24T23:44:31 < Laurenceb__> lets take a look
2015-07-24T23:44:42 < Laurenceb__> what is your raw datarate to the card?
2015-07-24T23:45:07 < Lux> like 100 kbyte/s
2015-07-24T23:45:21 < Lux> but that's like the maximum
2015-07-24T23:45:48 < Lux> yeah, but i guess that'd be rather time intensive to implement
2015-07-24T23:46:43 < Laurenceb__> hmm thats a lot faster than anything i do
2015-07-24T23:46:57 < Laurenceb__> looks like its going to block in https://github.com/Laurenceb/STM32-Logger/blob/master/Util/fat_fs/src/sd_spi_stm32.c
2015-07-24T23:47:03 < Laurenceb__> line 407
2015-07-24T23:47:51 < Laurenceb__> thats tricky :-/
2015-07-24T23:48:24 < Laurenceb__> I think the entire write datablock and read datablock functions would need to be rewritten
2015-07-24T23:49:00 < Laurenceb__> if you could live with interrupt driven spi for the wait_ready it woudnt be too hard
2015-07-24T23:49:07 < Laurenceb__> but thats still a lot of overhead
2015-07-24T23:49:57 < Lux> currently i've been messing around with an example that uses the sdio hardware on an stm32f4 http://mikrocontroller.bplaced.net/wordpress/?page_id=621
2015-07-24T23:50:21 < Laurenceb__> ah sdio
2015-07-24T23:50:29 < Laurenceb__> dunno how the wait is implimented therwe
2015-07-24T23:50:42 < Lux> it's actually pretty much the same as that stuff: http://stm32f4-discovery.com/2014/07/library-21-read-sd-card-fatfs-stm32f4xx-devices/
2015-07-24T23:50:51 < Lux> i need to read into that stuff more
2015-07-24T23:50:59 < Lux> just started like a day ago
2015-07-24T23:51:17 < Laurenceb__> hmm
2015-07-24T23:51:29 < Laurenceb__> ok so off the top of my head i can think of
2015-07-24T23:51:36 < Laurenceb__> 1) interrupt driven read loop
2015-07-24T23:51:51 < Laurenceb__> 2) timer with ~100µs delay to read and check status
2015-07-24T23:52:12 < Laurenceb__> but either way the rest of the code would have to be rewritten as a state machine
2015-07-24T23:52:19 < Laurenceb__> so you call it once and its non blocking
2015-07-24T23:52:46 < Lux> yep, seems like that's the way to go
2015-07-24T23:53:20 < Laurenceb__> quite a lot of work, but once you get to >>10kbps to the card it really need sdoing
2015-07-24T23:53:29 < Lux> or just use an rtos and let that it do all the timing management

2015-07-25T00:56:12 < karlp> Tectu: detection of the sensor being plugged in.
2015-07-25T00:56:43 < karlp> so, tip-ring-sleeve for vcc-signal-ground, and the 5pin jacks that can detect the plug
2015-07-25T00:57:02 < karlp> still a bit pointless, can't tell what sensor is connected :)
2015-07-25T00:57:12 < Tectu> karlp, heh
2015-07-25T00:57:33 < karlp> but if you have some common sensors and multiple inputs, you can at least work out which ones you need to read.
2015-07-25T00:57:51 < Tectu> karlp, why not taking a different type of connector?
2015-07-25T00:58:03 < karlp> like?  temp sensor came with three wires,
2015-07-25T00:58:07 < karlp> wanted compact, cheap, functional.
2015-07-25T00:58:23 < Tectu> makes sense
2015-07-25T00:58:46 < karlp> yeah, not unhappy with it.
2015-07-25T00:58:48 < Tectu> karlp, anyway, what I meant is that some people use the 3.5mm jack for the power supply of an entire device.
2015-07-25T00:58:54 < Tectu> karlp, not just some sensors
2015-07-25T00:59:01 < karlp> it's just a connector :)
2015-07-25T00:59:19 < karlp> these days I'd use microusb for power for anything.
2015-07-25T00:59:41 < karlp> always hated barrel jacks, at least 3.5mm was a more standard size,
2015-07-25T00:59:57 < Tectu> karlp, you short the PSU side every time you plug it in/out.
2015-07-25T01:00:04 < Tectu> or at least 95% of the time.
2015-07-25T01:02:16 < karlp> that depends on how you wire it, and what connectors you get
2015-07-25T01:02:39 < karlp> go look at the product catalog for 3.5mm sockets, you can get them in all sorts of configurations of shorting, non shorting.

2015-07-25T15:44:21 < Roklobsta> i think dongs has 4 arms and 2 heads, one set on irc and one on altium and absynth.
2015-07-25T15:44:47 < Laurenceb__> Lux: I took a look at my µSD code
2015-07-25T15:45:03 < Laurenceb__> looks like it rarely gets delayed in wait_ready
2015-07-25T15:45:36 < Laurenceb__> but I suspect thats because i use decent cards and I'm writing at relatively low speeds
2015-07-25T15:45:54 < Laurenceb__> I tried stress testing that same cards with PCIe card reading under linux
2015-07-25T15:46:25 < Laurenceb__> most delays were under 0.5ms, but there were some up to 9ms
2015-07-25T15:46:53 < Laurenceb__> itd be nice to look at delay versus write rate, but im not sure how to do that yet
2015-07-25T15:47:33 < Laurenceb__> my datalogger is usually ~10kB/s, linux was running at >10MB/s
2015-07-25T15:48:40 < dongs> zano is fucked they'll never be able to maintain 12meg/sec writes (for 1080p) to sd card with only 400k total ram
2015-07-25T15:49:21 < Laurenceb__> tl;dr  I suspect that at low write rates the card rarely delays, so most of the time you avoid wait_ready stuff, at least with decent cards
2015-07-25T15:49:23 < Laurenceb__> lol yeah
2015-07-25T15:49:34 < zyp> Laurenceb__, what do you mean about delay vs write rate? if you want to see when the card delays, you can check the signals with an LA
2015-07-25T15:50:02 < Laurenceb__> hmm good idea
2015-07-25T15:50:07 < dongs> up to 500ms is in the SD card spec
2015-07-25T15:50:12 < Laurenceb__> should solder some cables onto my card
2015-07-25T15:50:13 < Laurenceb__> lol
2015-07-25T15:50:14 < dongs> the card can delay up to that ay any time
2015-07-25T15:50:16 < zyp> I believe I have a screenshot of a slow-ass card somewhere, hang on
2015-07-25T15:50:21 < Laurenceb__> never seen >9ms anywhere
2015-07-25T15:50:31 < Laurenceb__> with sandisk cards
2015-07-25T15:51:05 < Laurenceb__> I suspect sandisk has a few sectors of internal buffer before the wear levelling
2015-07-25T15:51:35 < zyp> remember command timing is nondeterministic since it depends on internal state of the card
2015-07-25T15:51:53 < zyp> how many free sectors it have, or whether it'll have to wait to erase any
2015-07-25T15:53:13 < Roklobsta> dongs: how reliable are sd cards if the power fails?  my time with CF cards in embedded systems is if power is cut, throw the card out.
2015-07-25T15:53:17 < zyp> http://bin.jvnv.net/f/e16v1.png <- here's writes to some trash card

2015-07-25T16:06:13 < dongs> or 90meg/sec reads something like that. anyway read doesnt matter

2015-07-25T17:43:37 < ReadError> <Tekkkz> Tectu, im not sure, let me check it out
2015-07-25T17:43:40 < ReadError> o.0
2015-07-25T17:43:42 < zyp> Tekkkz, because dongs hates anything that's open
2015-07-25T17:43:54 < zyp> libopencm3 is decent
2015-07-25T17:44:04 < Tectu> ReadError, yeah, my face was the same.
2015-07-25T17:44:40 < Tectu> I used libopencm3 once and it was quite nice to use. However, afaik there is aboslutely no documentation beside the doxygen (which hover is quite enough together with the RM)
2015-07-25T17:44:49 < Tectu> also Makefile based which is a great plus for me
2015-07-25T17:45:29 < Tekkkz> so you recommend me to use libopencm3?
2015-07-25T17:46:00 < zyp> Tekkkz, what are you requirements?
2015-07-25T17:46:03 < zyp> your*
2015-07-25T17:46:04 < Tectu> Afaik you have not told us what you want to do, what your requirements are etc.
2015-07-25T17:46:06 < mitrax> tekkkz: have a look at the various libraries and make your mind :)
2015-07-25T17:46:31 < Tectu> mitrax, that´s actually the answer most beginners don´t like to hear when they ask for recommendations ;)
2015-07-25T17:47:56 < Tekkkz> yeah, i want to build a little robot, and i dont know if i need the CMSIS stuff or opencm3, or if opencm3 too far away from the real programming like with a lot of functions, e.g. for _toggle and so on – what is better to learn and to use for a robot?
2015-07-25T17:48:17 < mitrax> ok let me rephrase ;) look at the 2 or 3 that have been recommended and make your mind :)
2015-07-25T17:49:14 < zyp> Tekkkz, what do you mean by «real programming»?
2015-07-25T17:49:20 < Tectu> Tekkkz, if you want to get the robot done then a library like libopencm3 or even just the ChibiOS/HAL (where you can easly add the RTOS feature later on) will do. When you want to learn everything about the chip that you are using (I assume STM32) then grab the STM32Cube
2015-07-25T17:49:37 < Tectu> just my opinion, of course ^
2015-07-25T17:49:47 < zyp> Tectu, uh, what makes you say that?
2015-07-25T17:50:02 < Tekkkz> cube is just for windows - but its an ide right? so you mean the CMSIS stuff?
2015-07-25T17:50:29 < Tectu> zyp, libopencm3 comes with functions to set up clock stuff where you dont have to do anything. STM32Cube is just a HAL for the peripherals where you still have to manage the clock setups etc. yourself.
2015-07-25T17:50:51 < zyp> Tectu, don't have to doesn't mean you can't
2015-07-25T17:50:51 < Tectu> Tekkkz, STM32Cube is a library that you can download. Don´t confuse it with STM32CubeMX
2015-07-25T17:50:57 < mitrax> Tekkz: no STM32cube is a library, there is a cubeMX thing that's a program with a gui that generates things for you but you don't need to use that
2015-07-25T17:51:22 < Tectu> zyp, I agree.
2015-07-25T17:51:43 < mitrax> Tekkz: what IDE do you use at the moment?
2015-07-25T17:51:47 < zyp> Tekkkz, say, would you describe yourself as a «linux guy»?
2015-07-25T17:51:58 < Tectu> zyp, you can always use a higher-level library and still do some of the low-evel stuff yourself, I guess. But then you might want to directly opt for a lower-level one if you know that you want to do that.
2015-07-25T17:51:58 < mitrax> Tekkz: if you use one...
2015-07-25T17:52:07 < Tekkkz> mitrax, text editor!
2015-07-25T17:52:10 < Tekkkz> zyp, yes
2015-07-25T17:52:18 < Tekkkz> i work on linux only
2015-07-25T17:52:36 < zyp> Tekkkz, ok, then I'd recommend libopencm3, it should fit your mindset better than any of the vendor provided stuff
2015-07-25T17:52:54 < Tectu> indeed
2015-07-25T17:52:54 < Tekkkz> okay, and can you give me a little explanation why?
2015-07-25T17:53:07 < zyp> because it's designed by people with a similar mindset
2015-07-25T17:53:09 < Tectu> Tekkkz, because libopencm3 is written by linux people
2015-07-25T17:53:26 < Tectu> Tekkkz, what zyp said. It will just feel more familiar :)
2015-07-25T17:53:44 < zyp> Tectu, you make it sound like libopencm3 is a high level library, I'd say it's not
2015-07-25T17:53:46 < Tekkkz> hehe ok, so CMSIS=win, locm3=lin ?
2015-07-25T17:54:29 < Tectu> zyp, not exactly what I think, no. I wanted to say that there is stuff in there that you can call without caring about what happens.
2015-07-25T17:54:30 < Tekkkz> so i will use locm3, nice, but why you dont really like it zyp ?
2015-07-25T17:54:39 < zyp> Tekkkz, like what?
2015-07-25T17:54:42 < Tectu> zyp, I am mainly refering to the clock setup functions where there is a function call for nearly each setup
2015-07-25T17:55:22 < Tekkkz> zyp, like "i like a cake" -> you dont like locm3?
2015-07-25T17:55:35 < zyp> Tekkkz, what gave you that impression?
2015-07-25T17:55:47 < Tekkkz> <zyp> Tectu, you make it sound like libopencm3 is a high level library, I'd say it's not
2015-07-25T17:55:57 < Tectu> that does not mean that he does not like it
2015-07-25T17:56:03 < zyp> oh, haha
2015-07-25T17:56:17 < zyp> I mean level as in level of abstraction, not level of quality
2015-07-25T17:56:23 < zyp> it's certainly a good library
2015-07-25T17:56:37 < Tekkkz> ok, but you mainly use CMSIS?
2015-07-25T17:56:45 < zyp> no, I've never used CMSIS
2015-07-25T17:56:59 < Tectu> zyp, I bet you have used their device headers :D
2015-07-25T17:57:25 < Tekkkz> what do you use then zyp?
2015-07-25T17:57:32 < zyp> I don't use libopencm3 either, but I would if not for the fact that I started on my own lib before I found it
2015-07-25T17:58:02 < zyp> I use laks, which is not really mature enough that I'd recommend it to anybody who don't know what they're getting into
2015-07-25T17:58:05 < Tectu> oh, interesting, looks like karlp does some work on libopencm3
2015-07-25T17:58:11 < mitrax> Tekkz: you could use STM32cube just as well on linux, it just doesn't come with examples that can be compiled as is, you'll have to write a makefile, but it comes with linker script and startup asm code for gcc
2015-07-25T17:58:23 < zyp> Tectu, yes, he's pretty much the main maintainer nowadays
2015-07-25T17:58:32 < Tectu> zyp, did not know that.
2015-07-25T17:59:12 < Tectu> I guess when I would do a project w/o an RTOS (because I always pick ChibiOS for my own projects) then I would definitely use libopencm3 again
2015-07-25T17:59:39 < zyp> mitrax, but is the API decent enough that anybody would want to use it when it would be easier to use libopencm3?
2015-07-25T17:59:49 < Tekkkz> Okay, so someone says CUBE, someone says locm3 ... everytime the same problem: Someone likes smething and everything is liked by someone ... but for a newby is this a bad problem, cause now i still dont know what i should use :D
2015-07-25T18:00:02 < zyp> Tectu, I've heard of people using libopencm3 with chibios, because the chibios hal is dumb
2015-07-25T18:00:10 < Tectu> Tekkkz, I think we all told you that you should go for libopencm3 in your case ;)
2015-07-25T18:00:17 < Tekkkz> yeah
2015-07-25T18:00:27 < Tekkkz> 2 for locm3, one for cube, so locm3 has won :D
2015-07-25T18:00:57 < zyp> I thought it was a pretty well established opinion that cube is even more shit than stdperiph
2015-07-25T18:01:09 < Tectu> zyp, well, the time where I intensively used the ChibiOS HAL I had barely any experience at all. I had many issues with it but I would say it is due to my not-knowing-ness. These days I really just use the basic stuff to talk to displays and read some silly touchscreen controller via SPI.
2015-07-25T18:01:17 < zyp> I don't know cube, but I'd easily pick libopencm3 over stdperiph
2015-07-25T18:01:39 < mitrax> zyp: i have no idea :) i never used libopencm3, libopencm3 might be a better choice, it's just that STM32cube comes with lots of example for the various discovery boards so that might makes things easier if he wants to learn the chip through those board
2015-07-25T18:01:45 < Tectu> zyp, I have used stdperiph and stm32cube and personally I think that the cube is a bit of an improvement.
2015-07-25T18:01:46 < Tekkkz> okay thx for all help, i will now have a look at locm3, so cya guys
2015-07-25T18:01:56 < mitrax> zyp: though i assume there are some libopencm3 example for the discovery boards as well
2015-07-25T18:02:11 < zyp> mitrax, sure
2015-07-25T18:02:14 < Tectu> zyp, just talking about the HAL, the structure of examples and stuff is still crap. And documentation is useless of course

2015-07-25T18:03:23 < Tectu> mitrax, I never liked the STM32Cube examples... they are always so weird
2015-07-25T18:04:54 < mitrax> well for one thing the directory structure of the lib is completely fucked up, with files spread everywhere
2015-07-25T18:05:20 < Tectu> I also dont really like the way they do the BSP, MSP and other crap
2015-07-25T18:05:27 < Tectu> and so many  useless 1000 lines comments

2015-07-25T18:06:41 < mitrax> eheh yeah, well i only use the HAL stuff and rewrote what was needed for configuring the board, but it got me started... guess i should have looked at libopencm3 might have make things easier
2015-07-25T18:06:59 < Tectu> zyp, anyway, since ChibiOS 3.x the HAL is now a completely separate module. so using libopencm3 with the ChibiOS OS should be even simpler.

2015-07-25T18:09:34 < Tectu> ReadError, the discovery board is still a very good board for that price in my opinion but it is hard to prototype with it because you can not really probe things

2015-07-25T18:09:46 < ReadError> sorry
2015-07-25T18:10:05 < mitrax> Tectu: do you know if there's a 2MB flash version of the F7?
2015-07-25T18:10:19 < zyp> I don't think there are
2015-07-25T18:10:22 < mitrax> Tectu: i'm surprised they shrank the size from 2MB to 1MB :(
2015-07-25T18:10:28 < zyp> at least last I checked, only 1MB flash were announced
2015-07-25T18:10:28 < Tectu> mitrax, that is just what I was typing: The F4 is available in a 2MB but the F7 is not
2015-07-25T18:10:41 < mitrax> that sucks
2015-07-25T18:10:44 < Tectu> which I do not really understand as they seem to focus on more HMI touchscreen interface crap with the F7 where flash is nice.
2015-07-25T18:10:50 < mitrax> exactly
2015-07-25T18:10:55 < zyp> well, duh, don't be dumb
2015-07-25T18:11:05 < zyp> F7 doesn't need internal flash as much as F4 does
2015-07-25T18:11:14 < Steffanx> they added quad spi interface for more flash :P
2015-07-25T18:11:15 < mitrax> i'm using the F4 with the LCD and pack a lot of image / font resources in ROM
2015-07-25T18:11:20 < zyp> F7 can memory map qspi flash
2015-07-25T18:11:26 < mitrax> ah
2015-07-25T18:11:30 -!- DanteA [~X@host-56-156-66-217.spbmts.ru] has quit [Ping timeout: 240 seconds]
2015-07-25T18:11:33 < Tectu> zyp, yes, that is correct. A nice feature I forgot to mention
2015-07-25T18:11:40 < zyp> and cortex-m7 have cache, so it won't have much overhead to run from external memory
2015-07-25T18:11:53 < Tectu> mitrax, same here. I have an F4 application where the flash image is about 1.5 MB
2015-07-25T18:12:07 < zyp> Tectu, what do you run that on?
2015-07-25T18:12:10 < Tectu> ReadError, F7 status:  http://forum.chibios.org/phpbb/viewtopic.php?f=16&t=2717
2015-07-25T18:12:21 < zyp> Tectu, what's your experience with the 2MB flash errata?
2015-07-25T18:12:22 < ReadError> oh cool
2015-07-25T18:12:39 < Tectu> zyp, I would have to check. It is not my hardware but from a customer.
2015-07-25T18:12:48 < Tectu> zyp, I did not handle the flash part. I just build their GUI
2015-07-25T18:12:48 < zyp> right, ok
2015-07-25T18:13:21 < zyp> I designed some board for a customer and they want to upgrade to the 2MB flash version, which would be affected by that dumb PA12 errata
2015-07-25T18:13:30 < Tectu> zyp, I have not yet checked out the QSPI on the F7 but I plan to do that somewhen in August. When I remember correctly you can directly store things in a QSPI through the STLink
2015-07-25T18:13:40 < mitrax> zyp: what's that?
2015-07-25T18:13:43 < Tectu> zyp, at least their latest STLink Utility version claims to do that.
2015-07-25T18:13:48 < zyp> and rev 3 chips (which are unaffected) have so far proven to be important to source
2015-07-25T18:14:18 < zyp> Tectu, that's all software anyway
2015-07-25T18:14:21 < Tectu> zyp, what happens to be the issue with PA12? I have not heard about anything. Not sure what they did but they are definitely using a 2MB version
2015-07-25T18:14:41 < Tectu> zyp, might be, I dont know. i would have assumed that the QSPI needs some kind of JTAG interface for that
2015-07-25T18:14:53 < Tectu> zyp, I mean the QSPI peripheral, not the external chip
2015-07-25T18:14:58 < zyp> Tectu, accesses to second flash bank can be corrupted unless PA12 is held low
2015-07-25T18:15:11 < zyp> and as PA12 is one of the usb lines in my design, that'd be a problem
2015-07-25T18:15:21 < Tectu> zyp, whoops, That sounds unpleasant.
2015-07-25T18:15:29 < zyp> yes, it's dumb as fuck
2015-07-25T18:15:46 < Tectu> zyp, customer did not use USB, so they might not have the issue at all
2015-07-25T18:16:18 < zyp> if customer would have told me from the beginning that they had so much garbage data to store, I'd throw on an SPI flash for that
2015-07-25T18:17:29 < mitrax> zyp: but... PA12 is LCD_R5 ... that means if you use the LCD you're fucked?
2015-07-25T18:18:17 < mitrax> zyp: or does that happen only when PA12 is configured as an input?
2015-07-25T18:18:22 < Tectu> mitrax, when you use the LTDC you loos many pins. I dont think that zyp uses a LCD.
2015-07-25T18:19:13 < mitrax> Tectu: yeah but according to what he said PA12 has to be held low, and PA12 is used by LTDC
2015-07-25T18:19:24 < Tectu> mitrax, PA12 is used for his USB stuff.
2015-07-25T18:19:47 < mitrax> Tectu: yes, but he said "<zyp> Tectu, accesses to second flash bank can be corrupted unless PA12 is held low"
2015-07-25T18:19:48 < Tectu> mitrax, hence I dont assume that he uses the LTDC because you cannot remap LTDC pins when I remember correctly and bit 5 you will always use
2015-07-25T18:20:02 < mitrax> my question is, does the bug show up when you use the LTDC
2015-07-25T18:20:22 < Tectu> mitrax, aah, sorry. I thought you assumed that he is using LTDC
2015-07-25T18:20:25 < mitrax> no no
2015-07-25T18:20:26 < mitrax> i am :)
2015-07-25T18:20:30 < Tectu> :)
2015-07-25T18:20:42 < Tectu> mitrax, for personal knowledge, may I ask what LCD / GUI framework you are using?
2015-07-25T18:20:45 < mitrax> and i'm worried about what that errata thing, since at some point i'll need more than 1MB for the firmware
2015-07-25T18:20:48 < Steffanx> i would say yes, as usb affects it too mitrax .. but that's a" "guess"
2015-07-25T18:21:18 < mitrax> Tectu: my own :)
2015-07-25T18:21:35 < zyp> mitrax, anything using PA12 would
2015-07-25T18:21:44 < zyp> as I read the errata sheet
2015-07-25T18:22:25 < Tectu> zyp, so how did you solve the issue? shutting down PA12 on flash access? :D
2015-07-25T18:23:34 < zyp> I haven't
2015-07-25T18:23:51 < Tectu> so customer is complaining about your incopetence I guess?
2015-07-25T18:24:02 < zyp> the thing is, the design were originally made with F407, of which I've provided a series of protos
2015-07-25T18:24:30 < zyp> and then they figured out they wanted more flash, so they're asking for a series with F427VI
2015-07-25T18:25:58 < Tectu> zyp, so mouser is still not sourcing rev3?
2015-07-25T18:26:14 < zyp> I caught the PA12 issue when I reviewed whether F427VI would be drop-in compatible, noting that it's fixed in rev3, so only rev3 parts would be compatible
2015-07-25T18:27:08 < zyp> checked with distributors, found none with rev3 parts available, notified customer of their alternatives and they opted to wait until I get back from vacation
2015-07-25T18:27:16 < mitrax> zyp: the F429ZI would be affected too?
2015-07-25T18:27:22 < zyp> mitrax, yep
2015-07-25T18:27:37 < Tectu> mitrax, always read errata before picking a chip :)
2015-07-25T18:27:50 < Tectu> zyp, uhm, so rev3 still has the bug but it would work for your design? I do not understand.
2015-07-25T18:28:21 < zyp> Tectu, so considering I'm not providing a defective series for the customer, I don't see where there's any incompetence on my part
2015-07-25T18:28:38 < zyp> no, rev3 have the bug fixed
2015-07-25T18:28:59 < Tectu> zyp, what I meant is that customers usually yell at the engineer and complain about his competence to get some thing working. I know that it is not your fault :)
2015-07-25T18:29:04 < mitrax> zyp: how do you see what revision is it? is it part of the reference?
2015-07-25T18:29:44 < zyp> mitrax, you should probably just find and read the errata sheet, it also explains how to determine the revision
2015-07-25T18:29:53 < Tectu> zyp, have you worked with QSPI before?
2015-07-25T18:29:58 < zyp> no
2015-07-25T18:30:05 < zyp> why?
2015-07-25T18:31:24 < mitrax> zyp: what i mean is do you actually have to look on the physical chip or is there a way to know from the supplier (say mouser / digikey whatever)?
2015-07-25T18:31:41 < Tectu> zyp, just curious. I assume it will be a nice thing to use somewhen.
2015-07-25T18:32:07 < Tectu> zyp, I had to use a NAND flash on an F1 once. But the hardware dude screwed it up and did not hook it up to the FSMC properly so it had to be bit-banged.
2015-07-25T18:32:12 < zyp> mitrax, it's not part of the part number, so you'll have to ask the supplier
2015-07-25T18:32:17 < mitrax> argh
2015-07-25T18:33:05 < zyp> and the suppliers doesn't even seem to track that stuff internally, so I believe they had to send somebody to actually check what they had on the shelf :p
2015-07-25T18:33:58 < Steffanx> and they they got new ones, which are the wrong rev. and you re still screwed?
2015-07-25T18:34:03 < Steffanx> *then they
2015-07-25T18:37:03 < Tectu> looks like there is not a lot of QSPI stuff on the market
2015-07-25T18:37:10 < Tectu> (of course there are several, just not as much)

2015-07-25T19:39:34 < karlp> yeah, basic support for new parts isn't normally very complicated.
2015-07-25T19:40:14 < karlp> the f0/l0 brought out some new periphs that were only in the f3 before though, and it took some (is taking some) time to pull out common code for them.

2015-07-25T19:44:48 < Tectu> karlp, seen to many
2015-07-25T19:44:57 < Tectu> karlp, I will consider using libopencm3 for some ugfx demos then
2015-07-25T19:44:59 < karlp> what would shannon know, just some old greybeard right?
2015-07-25T19:45:00 < Laurenceb__> maybe with a very good LNA on the front
2015-07-25T19:45:13 < karlp> back whtn they thought the earth was flat and shit, who cares what he thinks
2015-07-25T19:45:24 < Laurenceb__> but silabs NF is already very low
2015-07-25T19:45:43 < emeb> karlp: and don't even get me started on Newton, or Pythagoras.
2015-07-25T19:45:56 < karlp> fucking triangles, how do they work!
2015-07-25T19:46:00 < Tectu> karlp, some people love GPL too much and think that everything needs to be GPL, you know
2015-07-25T19:46:10 < karlp> yeah, fuck those people
2015-07-25T19:46:29 < Steffanx> some people make up their own open sores but non-free license.
2015-07-25T19:46:35 < ReadError> Laurenceb__, i will get some more deets when it comes out
2015-07-25T19:46:38 < karlp> yeah, fuck them too, weirdos :)
2015-07-25T19:46:47 < ReadError> since im curious to see what they are doiong
2015-07-25T19:46:51 < Tectu> somebody enjoys fucking people
2015-07-25T19:46:58 < karlp> who doens't enjoy fucking?
2015-07-25T19:47:25 < Steffanx> depends on how and what ofcourse
2015-07-25T19:47:36 < Tectu> don´t go there, Steffanx
2015-07-25T19:47:54 < Lux> does using lgpl software on a microcontroller force one to at least give away the binaries ?

2015-07-25T19:48:22 < Lux> of the closed sores part
2015-07-25T19:48:33 < Tectu> ReadError, jup
2015-07-25T19:48:50 < Tectu> ReadError, most licensing is
2015-07-25T19:48:52 < qyx_> Lux: no
2015-07-25T19:48:57 < Tectu> many*
2015-07-25T19:50:13 < karlp> took to long to be funny, but did the work, gotta share the progress: https://www.youtube.com/watch?v=hx66LWV-CCk&t=0m43s
2015-07-25T19:50:40 < Lux> qyx_: but at least of the stuff that uses lgpl libs ?
2015-07-25T19:51:10 < karlp> Lux: yeah, binaries of the closed source part, together with anything required to relink a modified version of the open source part
2015-07-25T19:51:16 < qyx_> karlp: huh?
2015-07-25T19:51:28 < Lux> karlp: that's what i tought
2015-07-25T19:51:40 < karlp> Lux: but, only to people you've sold it too,
2015-07-25T19:51:48 < karlp> doesn't have to be public or anything
2015-07-25T19:53:21 < Lux> that's good, but it still seems a bit complicated to implement
2015-07-25T19:53:54 < karlp> meh, nobody said you had to be fully compliant from day one :)
2015-07-25T19:54:08 < karlp> it only has to be provided on demand,
2015-07-25T19:54:41 < karlp> but of course, that is a real obligation, you won't have that obligation with cmsis/cubestdlibtastic
2015-07-25T19:55:12 < karlp> I'd imagine any alrge project will end up having a bunch of licensing to deal with anywya, so just becomes part of that.
2015-07-25T19:55:56 < Lux> bsd licencing would be cool in that regard i guess
2015-07-25T19:56:11 < karlp> yes, but libopencm3 has gone a bit too far with too many contirbutors for that :)
2015-07-25T19:56:19 < karlp> mbed is possibly the best choice for that
2015-07-25T19:56:22 < Lux> but that also poses the danger that some company will just steal the code and not contribute for bugs etc
2015-07-25T19:56:28 < karlp> or clear up what laks is with zyp.
2015-07-25T19:56:36 < karlp> only if you regard that as a danger...
2015-07-25T19:57:08 < Lux> i guess that's why people love gpl
2015-07-25T19:57:25 < karlp> I think a lot of people love the gpl because they were told they should.
2015-07-25T19:57:40 < Lux> but that's just my uneducated guess ;)
2015-07-25T19:57:52 < karlp> people maintaining "fixed" versions of forks normally end up regretting not submitting fixes upstream as far as I can tell
2015-07-25T19:58:11 < karlp> the headache of backporting fixes, or refixing things in your own version can be a real pain
2015-07-25T19:58:36 < Lux> iirc that happened with the linux kernel a lot on embedded platforms
2015-07-25T19:59:01 < karlp> yup
2015-07-25T19:59:31 < Lux> at least the linux devs get a lot of paid work trough that
2015-07-25T20:00:00 < karlp> yeah, which is why more and more companies are demanding upstream kernels from vendors now :)
2015-07-25T20:00:28 < karlp> and why more and more hw vendors are gettting better and better atgetting their new products in upstream from day 1
2015-07-25T20:01:03 < karlp> still, net-snmp has checks in the configure scripts for kerlen 2.0 and 2.2 :)

2015-07-26T00:10:34 < kakimir_> yes
2015-07-26T00:10:37 < kakimir_> very true
2015-07-26T00:10:50 < kakimir_> just copying my files to click that icon
2015-07-26T00:11:05 < kakimir_> I bet it's gone after 2months of flashing there
2015-07-26T00:13:50 < trepidacious> It appears on some laptops at work that we don't want to reinstall, but not on my surface where I'm quite interested
2015-07-26T00:14:18 < trepidacious> I have no idea why they don't just let you go download some locked file instead
2015-07-26T00:14:32 < trepidacious> Presumably that's all the magic icon is doing
2015-07-26T00:14:51 < trepidacious> Maybe MS think my Windows isn't genuine
2015-07-26T00:16:37 < trepidacious> I'll update again and see if that fixes it

2015-07-26T01:36:27 < jadew> hmm, looks like gimp is the best alternative to photoshop

2015-07-26T04:58:52 < yan_> i noticed that 3 pins are used for i2c ports on the stm32l1, scl, sda and smba. can i assign the third to a different GPIO if i'm not using smbus?
2015-07-26T04:59:43 < jadew> yes
2015-07-26T05:00:06 < yan_> jadew: what is the pin typically used for, electrically? does it notify the mcu when there's data available?
2015-07-26T05:00:21 < yan_> one of the IC's im using has a 'data ready' pin, would i be able to just connect it to smba?
2015-07-26T05:01:06 < jadew> possibly, you'll have to read the docs
2015-07-26T05:01:14 < jadew> I believe that SMBA will trigger an interrupt

2015-07-26T05:57:13 < kakimir_> didn't see unhealthy skinny or fat
2015-07-26T05:57:49 < kakimir_> generally well nutried people I would say
2015-07-26T05:58:28 < jadew> kakimir_, where are you from?
2015-07-26T05:58:45 < jadew> your point of reference matters too
2015-07-26T06:00:37 < kakimir_> finland
2015-07-26T06:02:03 < jadew> looks like you're a bit higher on the obesity scale than we are, but pretty average I guess
2015-07-26T06:02:44 < kakimir_> but there is more skinny people too
2015-07-26T06:02:47 < kakimir_> lots of
2015-07-26T06:03:27 < jadew> I bet
2015-07-26T06:04:07 < jadew> R2COM, where is here?
2015-07-26T06:04:16 < jadew> ah
2015-07-26T06:04:44 < kakimir_> okay russia and baltia... everybody in shape
2015-07-26T06:04:47 < jadew> that might be the more important issue
2015-07-26T06:05:31 < jadew> russia seems to have more obese people than finland
2015-07-26T06:05:53 < kakimir_> how they...
2015-07-26T06:06:10 < jadew> R2COM, if they don't feel like taking care of themseleves, then odds are they won't be too excited about loosing a few pounds

2015-07-26T06:27:54 < yan_> can i use any gpio line as an exti interrupt source on the L1?
2015-07-26T06:30:03 < jadew> yan_, check the datasheet
2015-07-26T06:30:15 < jadew> it should have a map of all the functions every GPIO can take
2015-07-26T06:34:48 < yan_> jadew: exti isn't an alternate function, i don't think. the datasheet just says that it has 23 edge detector lines and up to 83 gpios can be connected, which made me assume arbitrary gpios can be used as exti sources
2015-07-26T06:36:18 < kakimir_> aren't exti usually some certain pin?
2015-07-26T06:37:34 < yan_> kakimir_: that's what i'm asking. in the past i've jused use the GPIO and the pin number in the exti setup function, i'm trying to figure out if i can apply that to any pin on the mcu
2015-07-26T06:38:26 < jadew> yan_, check the datasheet
2015-07-26T06:39:02 < yan_> jadew: i did.
2015-07-26T06:39:12 < jadew> and it's not there?
2015-07-26T06:40:11 < yan_> nope. i'm checking the reference manual now
2015-07-26T06:41:38 < kakimir_> can you usually mux exti in stm32 chips?
2015-07-26T06:42:18 < yan_> ok yeah looks like i can effectively trigger on any gpio
2015-07-26T06:42:29 < jadew> regardless of AF?
2015-07-26T06:42:35 < yan_> yes
2015-07-26T06:42:40 < jadew> interesting
2015-07-26T06:42:48 < yan_> i don't think exti is considered an AF
2015-07-26T06:42:58 < yan_> exti controller has all the pins muxed from different gpios
2015-07-26T06:43:09 < yan_> i.e. all pin 0s from gpioa,b,c,etc, all 1's, all 2's, etc
2015-07-26T06:43:15 < yan_> this is on L1

2015-07-26T15:20:56 < Tekkkz> Hey Tectu, zyp ; Do you remember my aim? (Making a robot)... I asked what I should use to program the ARM (locm3 or CMSIS) but now I got the idea, cause I like Java a lot, if it is possible to program the STM32F103C8T6 in Java?
2015-07-26T15:21:10 < Steffanx> ther eis a java stm32 :P

2015-07-26T15:21:26 < Tectu> Laurenceb__, there is
2015-07-26T15:21:32 < trepidacious> Tekkkz: Not really - if you wanted to use something higher level, you should maybe look at a higher end MCU?
2015-07-26T15:21:34 < Tectu> Tekkkz, dont do that, really.
2015-07-26T15:21:46 < trepidacious> Tekkkz: 103 is low end and old even for a small MCU
2015-07-26T15:21:54 < Tekkkz> Yeah i know
2015-07-26T15:21:59 < trepidacious> Tekkkz: Although for some reason everyone still wants to use them for absolutely everything
2015-07-26T15:22:02 < Tectu> Tekkkz, Maybe you want to look at getting an Arduino. They provide a higher-level code library

2015-07-26T15:22:41 < Tectu> Tekkkz, Java is not meant to run on something like an STM32. Well, the author wanted it to run on embedded systmens but it is really not designed for that.

2015-07-26T15:22:50 < Laurenceb__> java on stm32...
2015-07-26T15:22:55 < trepidacious> Tekkkz: Maybe use something like a cheapish SBC? E.g. Raspberry Pi?
2015-07-26T15:22:59 < ReadError> isnt there Java STM32 series?
2015-07-26T15:22:59 < Laurenceb__> youd have to be literally insane
2015-07-26T15:23:05 < Tekkkz> nono i dont need java
2015-07-26T15:23:08 < Tectu> Tekkkz, most people use C++ on STM32
2015-07-26T15:23:09 < ReadError> like some J chips or something
2015-07-26T15:23:22 < trepidacious> Tectu: Or honest to goodness C, none of this ++ stuff! ;)
2015-07-26T15:23:24 < Tekkkz> ahh C++? hm, why? why not just C?
2015-07-26T15:23:37 < Steffanx> those chips really exist in the real world ReadError?
2015-07-26T15:23:47 < ReadError> Steffanx i duno ;) never cared to find one
2015-07-26T15:23:52 < ReadError> just saw it on the site a while ago
2015-07-26T15:24:03 < Tectu> Because C++ offers many advantages over C while the only real drawback to use it on an MCU are the huge libraries to which there are already many alternatives
2015-07-26T15:24:12 < Tectu> talk to zyp about what libraries he uses
2015-07-26T15:24:17 < Steffanx> http://www.stm32java.com/ such greatness

2015-07-26T15:25:00 < ReadError> they are for sale apparently
2015-07-26T15:25:02 < Laurenceb__> and mechanical sequencing
2015-07-26T15:25:04 < Laurenceb__> works fine
2015-07-26T15:25:12 < Tekkkz> whatever i will just programm it in C for this moment, maybe later i switch to c++
2015-07-26T15:25:20 < Tectu> Tekkkz, sounds like a good plan
2015-07-26T15:25:27 < Tectu> Tekkkz, and libopencm3 will get the job done for sure

2015-07-26T15:26:04 < Tekkkz> okay thx
2015-07-26T15:26:23 < trepidacious> Tectu: Have you gone off ChibiOS?
2015-07-26T15:26:47 < Tectu> trepidacious, nope, never. ChibiOS is my main OS
2015-07-26T15:27:04 < Tectu> trepidacious, the only reason why I wouldnt use ChibiOS is when some customers use something different
2015-07-26T15:27:34 < Sync_> Tectu: come on it is ##stm32 :P

2015-07-26T15:28:35 < Tectu> ReadError, agreed
2015-07-26T15:28:41 < ReadError> besides the USB crap which I rage quit on
2015-07-26T15:29:15 < Steffanx> but that usb..
2015-07-26T15:29:18 < Steffanx> *that's
2015-07-26T15:29:30 < ReadError> Steffanx well the stdperiph one worked
2015-07-26T15:29:48 < ReadError> but even demo code nogusta on f0 I tried ;/
2015-07-26T15:29:58 < ReadError> will try again sometime maybe I overlooked something stupid
2015-07-26T15:30:01 < Steffanx> oh the remapping issue?
2015-07-26T15:30:14 < ReadError> yea, could possibly be related to that
2015-07-26T15:30:30 < ReadError> it was just failing to enumerate on OS
2015-07-26T15:30:36 < ReadError> so it was trying to do *something*
2015-07-26T15:30:53 < Tekkkz> Tectu, what is ChibiOS?
2015-07-26T15:31:23 < Sync_> look it up
2015-07-26T15:31:29 < Tekkkz> i did
2015-07-26T15:31:38 < Tekkkz> but are there any examples?
2015-07-26T15:32:00 < ReadError> tons
2015-07-26T15:32:59 < trepidacious> Tectu: I found ChibiOS stuff easier to understand than non RTOS code, although I guess I've run into all the threading stuff before on non-embedded code
2015-07-26T15:33:12 < Tekkkz> ahh found some
2015-07-26T15:33:28 < trepidacious> Tectu: I was actually kind of amazed how advanced the threading support was, it actually has a nicer set of features than say C# on ,net ;)
2015-07-26T15:33:49 < ReadError> ya the HAL stuff is great
2015-07-26T15:33:53 < Tectu> ChibiOS might as well be a synonym for examples
2015-07-26T15:34:06 < trepidacious> I need to look at USB again, I was thinking of trying the cube host stuff, maybe host serial, but I hate USB :(
2015-07-26T15:34:10 < trepidacious> It's so goddamn complicated
2015-07-26T15:34:17 < Tectu> trepidacious, ChibiOS is quite nice indeed

2015-07-26T15:34:38 < Tectu> trepidacious, but going RTOS while being new in the real embedded world w/o any threading and other OS experience might be difficult
2015-07-26T15:35:01 < trepidacious> Tectu: I dunno, you can still just write stuff in the main thread if you want to, it won't do you any harm
2015-07-26T15:35:10 < trepidacious> Tectu: Then when you want more threads, you have them
2015-07-26T15:35:19 < Tectu> trepidacious, I never got the guts to mess with USB. i always copied the ChibiOS CDC stuff as I never had to do any other USB stuff
2015-07-26T15:35:48 < trepidacious> TBH if an embedded project is your first contact with threading, you might find EVERYTHING confusing - personally I would try to get the hang of coding for a more forgiving target like a PC first :)
2015-07-26T15:35:53 < Tectu> trepidacious, board files...
2015-07-26T15:36:15 < ReadError> trepidacious the threading stuff can be ignored though ??

2015-07-26T15:37:11 < trepidacious> ReadError: A lot of it can, if you don't actually need threads, just do stuff in main, or fire up one additional thread and use that. The point is you shouldn't need thread synchronisation or communication if you don't want it
2015-07-26T15:37:41 < trepidacious> I could be wrong, but I think stuff like GPIO, setting up timers, SPI/I2C etc. can all be done from one thread if you want to?
2015-07-26T15:39:31 < ReadError> you dont even need to use a thread though
2015-07-26T15:40:12 < Tectu> trepidacious, the baord files are nice as long as you dont have to mess with them. After a year I stopped messing with ChibiOS board files at all. I always initialize my GPIO crap using the PalSetPadMode() and other stuff inside proper init routines.
2015-07-26T15:40:44 < trepidacious> Tectu: Ah right, I guess there's no reason not to

2015-07-26T15:41:32 < ReadError> should make porting easier

2015-07-26T15:42:18 < trepidacious> I've used it to build the same stuff on different boards, when we moved pins around between PCB revisions
2015-07-26T15:42:38 < ReadError> yea just only reference the pinname
2015-07-26T15:42:44 < trepidacious> You can achieve the same thing through different means though like Tectu, just have different defines for different configurations etc.
2015-07-26T15:42:52 < ReadError> yea thats true too
2015-07-26T15:43:03 < Tectu> trepidacious, look show uGFX implements board files.
2015-07-26T15:43:28 < Tectu> trepidacious, there is always a board_init() and board_postInit() for each piece of hardware that you need to interface (each driver chip)
2015-07-26T15:43:42 < Tectu> trepidacious, so in there  you just set up the GPIO stuff like you need it - just the ones for that chip
2015-07-26T15:44:20 < Tectu> board_postInit() is not reallyu required, tho. That is due to the fact that some chips allow using a higher bus frequency after proper initialization.

2015-07-26T15:47:30 < Tectu> trepidacious, also, that way if people are into stuff like chibios board files that are actually set up correctly they can just leave board_init() empty
2015-07-26T15:47:39 < Tectu> so everybody is happy \o/
2015-07-26T15:48:06 < trepidacious> :) I must try ugfx, but I've not had any call to do stuff with screens
2015-07-26T15:48:38 < Tectu> trepidacious, sure, give it a go :)
2015-07-26T15:49:02 < Tectu> trepidacious, you can get quite decent TFT+touchscreen modules for 20 to 30 bucks
2015-07-26T15:49:07 < Tectu> and cheap ones for like 5 to 6 bucks
2015-07-26T15:49:35 < Tectu> look at this in case of you want to get something with an existing driver: http://ugfx.org/platforms

2015-07-26T15:53:54 < Tectu> trepidacious, I used threes screens with capacitive screens so far (The F7 discovery got one too)
2015-07-26T15:54:00 < Tectu> trepidacious, but define high-res
2015-07-26T15:54:17 < Tectu> ReadError, the F429 disco is supposed by uGFX but the screen on that board SUCKS ARSE
2015-07-26T15:54:50 < Tectu> ReadError, if you can, get an F7 discovery. great board. decent screen and very good capacitive touchscreen. the touchscreen controller even support multi-touch and gestures.
2015-07-26T15:54:58 < ReadError> Tectu i have one ;)
2015-07-26T15:55:06 < ReadError> im just waiting on chibios
2015-07-26T15:55:11 < Tectu> ReadError, tried it yet? stuff is in ugfx repo
2015-07-26T15:55:15 < Tectu> ReadError, ah, I see
2015-07-26T15:55:32 < Tectu> ReadError, the demo in the ugfx repo is ready-to-run including a memory manager and threading
2015-07-26T15:55:40 < Laurenceb__> is the front of the F7 screen glass or plastic?
2015-07-26T15:55:43 < ReadError> but have something else i need to finish before i even touch it
2015-07-26T15:56:38 < trepidacious> Tectu: I'll have to see about an F7 discovery. For high-res I was really thinking of highish dpi, maybe 250 or more?
2015-07-26T15:57:06 < Tectu> Laurenceb__, the touchscreen crap is not built into the panel like on modern smartphones. it is a glas plate that is sticked on top of the display. However, there is a permanent plastic film on top of the glas (but feels great)
2015-07-26T15:57:19 < Laurenceb__> ah i see

2015-07-26T17:46:43 < naquad> hi
2015-07-26T17:47:45 < naquad> is there a general delay function not utilizing (or hiding away) sys tick configuration?
2015-07-26T17:47:55 < naquad> like AVRs _delay_*?
2015-07-26T17:47:56 < Lux> Laurenceb__: i did some more testing with that sdcard stuff, i get like delays around 5ms for writing 8192 bytes
2015-07-26T17:48:04 < Lux> with peaks up to 100ms
2015-07-26T17:49:27 < Lux> i guess with writing raw to the card one could buffer it properly, but the fatfs kinda makes it slow, as it has to read the card too at some point before writing
2015-07-26T17:49:43 < Laurenceb__> wow
2015-07-26T17:49:50 < Laurenceb__> what brand card?
2015-07-26T17:49:57 < Lux> kingston
2015-07-26T17:49:58 < Laurenceb__> that seems very slow
2015-07-26T17:50:22 < Laurenceb__> you say delays, do you mean a single 100ms delay?
2015-07-26T17:50:30 < Lux> ya
2015-07-26T17:50:44 < Lux> like 100*~5ms and once 100
2015-07-26T17:50:59 < Lux> it's pretty random
2015-07-26T17:51:22 < Lux> but i was also writing at full speed
2015-07-26T17:51:58 < Laurenceb__> I've seen lots of ~5ms delays
2015-07-26T17:52:01 < Laurenceb__> never 100ms
2015-07-26T17:52:06 < Laurenceb__> with sandisk
2015-07-26T17:52:35 < Laurenceb__> whats you clk speed on SDIO?
2015-07-26T17:52:37 < Lux> but that was also writing at 1mb/s
2015-07-26T17:52:41 < Laurenceb__> ah
2015-07-26T17:52:54 < Laurenceb__> I had issues with high clk speeds on spi, it was very weird
2015-07-26T17:53:18 < Lux> iirc the clock speed should be 24mhz
2015-07-26T17:55:03 < Laurenceb__> iirc I use only 4.5mhz atm
2015-07-26T17:55:21 < Laurenceb__> erm no 9
2015-07-26T17:55:41 < Laurenceb__> but 18 wasnt reliable, very off
2015-07-26T17:55:43 < Laurenceb__> *odd
2015-07-26T17:56:20 < Laurenceb__> I never worked out if it was a PCB issue, it seemed to work 100% of the time on one of my prototype boards, but i never ran stress tests
2015-07-26T17:56:42 < Laurenceb__> on production PCB it would fail to init the card a few % of the time
2015-07-26T17:56:56 < Laurenceb__> and repeatedly - seemed to be temperature related or something
2015-07-26T18:01:27 < Laurenceb__> most cards are supposed to support 25mhz spi clk
2015-07-26T18:02:40 < Lux> stange
2015-07-26T18:02:44 < Lux> *strange
2015-07-26T18:02:51 < Lux> i even get those ~100ms delays at lower rates (writing 22 bytes per ms)
2015-07-26T18:03:09 < Lux> but i use the multiblock mode to speed it up a bit
2015-07-26T18:03:22 < Lux> writing 8192 bytes in one chunk
2015-07-26T18:03:58 < Laurenceb__> yeah the delay is from the wear leveller
2015-07-26T18:04:14 < Laurenceb__> I'm guessing different manufacturers use different techniques
2015-07-26T18:04:26 < Lux> most likely
2015-07-26T18:04:30 < Laurenceb__> like more/less internal buffering
2015-07-26T18:07:33 < Lux> and ofc it's cheaper to do less
2015-07-26T18:10:07 < naquad> has anyone used that: http://www.lctech-inc.com/Hardware/Detail.aspx?id=bf7963fc-bb3f-43d6-a628-fa2adfa985d5 ?

2015-07-26T19:15:36 < Fleck> np if easier for you! :)
2015-07-26T19:16:27 < Fleck> connecting 4 wires is not hard also! :)
2015-07-26T19:16:42 < naquad> well, yeah, but for that i would need to buy stlink anyway
2015-07-26T19:18:45 < Fleck> well, you should have one stlink dongle handy anyway :D
2015-07-26T19:18:59 < Fleck> I have two of them :p
2015-07-26T19:19:36 < Fleck> but ok, you should know better! :)
2015-07-26T19:19:43 < Fleck> book name btw?
2015-07-26T19:21:50 < naquad> Discovering STM32 Microcontroller
2015-07-26T19:22:22 < Tectu> the best book you can read is the RM + Wikipedia
2015-07-26T19:22:24 < ReadError> book.pdf ?
2015-07-26T19:22:29 < naquad> yes :)
2015-07-26T19:22:36 < ReadError> ah yes good
2015-07-26T19:23:00 < naquad> Tectu, before Reference Manual i'll first take a look around
2015-07-26T19:23:09 < naquad> for now its overwhelming after AVRs
2015-07-26T19:23:14 < naquad> but looks promising
2015-07-26T19:23:35 < Tectu> yeah, was the same for me back then
2015-07-26T19:23:41 < Tectu> still missing the simplicity of AVrs, tho
2015-07-26T19:23:43 < Tectu> AVRs*
2015-07-26T19:23:55 < Fleck> +1 here
2015-07-26T19:24:18 < Tectu> but definitely not missing PICs D:

2015-07-27T05:04:42 < Rickta59> you click on the "Show Heap Status" in the Window Preferences/General to see how much it is using. Spell check usually consumes a bunch of useless/useful memory

2015-07-27T05:07:46 < Rickta59> * running Luna on Ubuntu 14.04
2015-07-27T05:09:21 < decimad> Rickta59 Well, I like templates, the cdt indexer not so muchg, seemingly
2015-07-27T05:09:48 < Rickta59> c++ templates? or something else?
2015-07-27T05:09:54 < decimad> yeah
2015-07-27T05:10:00 < Rickta59> i have that also

2015-07-27T05:19:56 < decimad> no, no boost
2015-07-27T05:19:56 < Rickta59> just custom small ones that don't use any stdc++
2015-07-27T05:21:08 < Rickta59> mine are pretty simplistic just abstracting peripherals
2015-07-27T05:21:34 < decimad> mine are too, they're helping me with fixed point f.e. ;)
2015-07-27T05:22:17 < decimad> or well, yeah, I do have templates for clock and ping configuration... otherwise for containers etc..
2015-07-27T05:26:35 < zyp> uh, I don't think they qualify as simplistic as soon as you get metaprogramming in there
2015-07-27T05:28:32 < decimad> zyp vc++2015 intellisense actually manages to calculate all the stuff on the fly... pretty amazinh
2015-07-27T05:37:49 < decimad> it's a shame you can do floating point in constexpr now, but still not as template arguments :( Need macros because of that :(

2015-07-27T08:24:35 < jadew> heh, in that case I could get it from my PC's ROM :P
2015-07-27T08:25:03 < Roklobsta> do you want something ready to go as a C array?
2015-07-27T08:25:21 < jadew> Roklobsta, not necessarily, I can create the array from anything as long as the font looks good
2015-07-27T08:25:46 < jadew> hmm, now that I say it outloud, I guess I should just make a program to generate fonts
2015-07-27T08:26:14 < jadew> (from the system ones)
2015-07-27T08:26:17 < Roklobsta> let me google that for. you.  ah  http://dreamsware.info/fontgen/
2015-07-27T08:26:35 < jadew> heh, cool
2015-07-27T08:26:50 < Roklobsta> anything font you want
2015-07-27T08:26:56 < jadew> thanks, yeah, that looks great
2015-07-27T08:28:11 < Roklobsta> nothing is new
2015-07-27T08:28:24 < Roklobsta> if you can think of it, some arse has done it
2015-07-27T08:28:24 < jadew> I don't think that program is free
2015-07-27T08:28:30 < jadew> yeah, I'm sure
2015-07-27T08:28:42 < Roklobsta> "You can download and use FontGen free of charge. "
2015-07-27T08:29:11 < jadew> where is that?
2015-07-27T08:29:13 < jadew> For the details, you can check the trial version or check a sample font definition file which can be accessed here; as C and H (and common H) file.

2015-07-27T09:00:43 < dongs> The superMHL standard makes use of VESA's Display Stream Compression (DSC) standard version 1.1 to allow for 2.0x, 2.5x, or 3.0x compression. This allows a superMHL source-to-sink connection to transfer 108Gbps of visually lossless (mathematically lossy) data.

2015-07-27T09:01:41 < PeterM> it's not 108gbps then if you're losing that data is it then
2015-07-27T09:01:51 < icee> it's all lossy in one way
2015-07-27T09:01:56 < dongs> 7680x4320@24/25/30/50/60/120 Hz (8K UHD)
2015-07-27T09:01:56 < icee> e.g. we quantize it to a given bitdepth
2015-07-27T09:02:49 < icee> e.g. would you rather have 12bpp dynamic range, compressed 2x, or 8bpp?  the former might look better...
2015-07-27T09:02:58 < dongs> man i hope this supermhl shit dies a fiery death
2015-07-27T09:02:59 < dongs> On January 6, 2015, MHL introduced the new reversible superMHL connector. This 32 pin connector can carry concurrent video, data and power charging all in a slim, consumer-friendly form factor. A reversible design means that consumers don't have to worry about the plug's orientation or the cable's direction.
2015-07-27T09:03:07 < dongs> 32 fucking pins just for DRM
2015-07-27T09:03:13 < dongs> yet another fucking connector

2015-07-27T15:03:37 < zyp> sounds related to stmia/ldmia, but idk what rfe is
2015-07-27T15:03:50 < zyp> or rather, stmdb
2015-07-27T15:04:09 < zyp> since it's ia sp!, I assume it's a sort of pop
2015-07-27T15:04:38 < zyp> oh, return from exception perhaps
2015-07-27T15:05:01 < zyp> yeah, pop and return

2015-07-27T15:17:03 < zyp> yes, that would be way too much
2015-07-27T15:17:32 < dongs> zyp, in thread mode, unprivileged. swi. it does stuff swi is in handler mode. and needs to return torhead mode, unprivileged. bxlr wont work

2015-07-27T15:18:27 < zyp> dongs, sure it would
2015-07-27T15:18:47 < dongs> when cpu switches from thread to handler, will LR even contain valid info?
2015-07-27T15:19:01 < zyp> lr would contain an EXC_RETURN value rather than the actual return addr
2015-07-27T15:19:24 < zyp> which would instruct the cpu to do an exception return, popping the real return addr from the stack and changing modes and everything

2015-07-27T15:20:27 < zyp> cortex-m gets away with not requiring a special exception ABI by sticking EXC_RETURN into lr on ISR entry, so that the ISR can do whatever a normal function would do
2015-07-27T15:21:20 < zyp> EXC_RETURN itself contains bits that tells the cpu whether you're returning to privileged or unprivileged, msp or psp, etc…

2015-07-27T16:35:53 < aandrew> perhps I need to add a "quit' to the end of the script
2015-07-27T16:36:08 < karlp> PaulFertser: it's my regyular complain that the manual is only useful when you know what you're looking for, I know where that is described in the manual because I struggled to find it, after failing and having no threads and crashes. aandrew had the same thing.  I shouldna't have to fail first, then maybe if I start to know the manual really well, I can know where to find solutions.  I should be able to find things first, or not need to find things.
2015-07-27T16:36:11 < dongs> zyp, well, its possible. but would be custom and ~more expensive. for 2L probly down to 0.3 OK.
2015-07-27T16:36:28 < aandrew> yay, thread info!

2015-07-27T16:45:16 < aandrew> PaulFertser: I had to also follow the directions in the comments and add -Wl,--undefined=uxTopUsedPriority to my LDFLAGS since I am using -gc-sections

2015-07-27T17:39:08 < trepidacious> I don't really know a lot about MSVC either, I've used eclipse and it can barely even cope with basic C, it always has hundreds of compile errors because it doesn't understand the makefile I guess
2015-07-27T17:39:48 < decimad> well, hard float comes with cost... and you can't count on having fp in first place if you're writing a lib for use in embeded stuff
2015-07-27T17:42:15 < trepidacious> Yup, I was only half serious, I really don't miss having to do fixed point though, really nice having hard float

2015-07-27T17:45:55 < decimad> because of this convenience advantage I tried to make c++ help writing fixed-point code... can't beat hand optimized assembly obviously, but the results are pretty solid, when looking at output assembly

2015-07-27T19:38:59 < karlp> but with no cmake file, and no makefile, I couldn't get it oaded up meaningfully in either netbeansof clion.
2015-07-27T19:39:33 < karlp> I tried makign a project from scratch in netbeans, but I've never used it that way before, so I probably just havn't found the right options in the gui for it :)
2015-07-27T19:39:52 < karlp> but currently I can't even compile the test code, so no chance to see i how the intellisense would even work :)
2015-07-27T19:42:52 < decimad> karlp my production code using the lib uses gcc ... I checked out, added include path (which makes the tests compile as well) and just used it with no probs... I'll need to learn about cmake... Since there is not actually anything that has to be built, I wonder what the function of it would be
2015-07-27T19:43:32 < karlp> yes, I'm using gcc tooo, but I still need something to build it with.

2015-07-27T19:43:43 < karlp> I'm betting you don't invoke gcc manually on the command line...
2015-07-27T19:43:52 < decimad> Granted, it could generate a project where the tests/examples are compiled
2015-07-27T19:44:18 < decimad> karlp no, I use eclipse for that ;)
2015-07-27T19:44:50 < karlp> well, you didn't include an eclipse .project file either :)
2015-07-27T19:44:54 < decimad> karlp would visual studio solution/project files inside the distribution help you?
2015-07-27T19:45:11 < karlp> that's probably the least useful actually :)
2015-07-27T19:47:34 < decimad> well, I just need to know what that cmake script is supposed to do... I use these libs not as sub-projects in my own code but simply drop the git repository in the as a submodule and use them right away, no projects involved... So I would need to know what the standard behaviour for a header only-library would be, I don't know what it should do ;)
2015-07-27T19:47:59 < karlp> I don't knwo cmake either, but I couldn't get cmake or netbeans gui to do anything useful.
2015-07-27T19:49:52 < decimad> well, there's no cmake script and no netbeans project file ;)
2015-07-27T19:50:08 < karlp> no shit, there's no nothing

2015-07-27T19:51:05 < decimad> I would need to adapt some script, say from the luabind-deboostified thingy... let me see

2015-07-27T19:51:15 < karlp> what am I on now then?
2015-07-27T19:51:19 < karlp> I think I've got a cmake file working
2015-07-27T19:51:41 < karlp> oh, you need c++14? or gnu++1y or something?
2015-07-27T19:53:37 < decimad> well, I didn't get that error yet... somehow my compilers are set up to accept c++14 I believe... though that can be changed, there's no inherent need for auto there, just for brevity...
2015-07-27T19:54:31 < decimad> also this function isn't used anymore, nice you mention it ;)
2015-07-27T19:54:45 < Rickta59> if you do a build decimad in eclipse it will generate a bunch of makefiles in the output directory
2015-07-27T19:54:52 < Rickta59> you can use those without eclipse to build

2015-07-27T20:16:02 < karlp> decimad: what are you talking about 14 vs 11? you can make your whole thing 14, that's fine,
2015-07-27T20:16:08 < karlp> but it doesn't build in either 14 or 11...
2015-07-27T20:16:30 < Laurenceb> hmm no
2015-07-27T20:16:31 < decimad> karlp i'm talking two different things
2015-07-27T20:16:38 < Laurenceb> my backup register setting arent saved
2015-07-27T20:17:22 < Laurenceb> does anyone have an example of their use?
2015-07-27T20:19:05 < decimad> karlp: the updated example in local_test.cpp (latest commit) compiles now in gcc 4.9.
2015-07-27T20:19:40 < decimad> using c++14 that is, the auto there you see... that decltype(...) there would just be ugly to get c++11 conformance

2015-07-27T20:23:53 < karlp> yes, hooray, now it compiles :)
2015-07-27T20:24:39 < decimad> I hope c++17 will allow constant definitions within constexpr functions...
2015-07-27T20:24:59 < Steffanx> heh, i read the same.. and wonder the same thing dekar_ :D
2015-07-27T20:25:04 < decimad> I could also define them inside the arithmet expression, but that would be too ugly
2015-07-27T20:25:34 < Steffanx> lol even dongs twitter account gets referenced in that zano article :D :D

2015-07-27T23:27:17 < Laurenceb__> ok I'm confused
2015-07-27T23:27:19 < Laurenceb__> ((uint16_t*)&f)[1]
2015-07-27T23:27:36 < Laurenceb__> where f is a float
2015-07-27T23:27:45 < Laurenceb__> that should be two bytes of f right?
2015-07-27T23:28:12 < Laurenceb__> its giving my two bytes at address of f +4 bytes
2015-07-27T23:30:04 < englishman> Ya...
2015-07-27T23:30:12 < englishman> [1]
2015-07-27T23:30:32 < Lux> bytes 3 and 4
2015-07-27T23:30:33 < englishman> Remember arrays are 0 indexed?
2015-07-27T23:30:55 < Lux> or 2 and 3 indexed 0 ^^
2015-07-27T23:31:03 < Laurenceb__> sure
2015-07-27T23:31:18 < Laurenceb__> ((uint16_t*)&f)[0] works fine
2015-07-27T23:31:37 < Laurenceb__> ((uint16_t*)&f)[0] jumps by 4 bytes, not two
2015-07-27T23:31:42 < Laurenceb__> arg
2015-07-27T23:31:45 < Laurenceb__> ((uint16_t*)&f)[1] jumps by 4 bytes, not two
2015-07-27T23:33:03 < englishman> Float is 32bit?
2015-07-27T23:33:15 < Laurenceb__> yes
2015-07-27T23:33:28 < englishman> Yes
2015-07-27T23:33:30 < englishman> ...
2015-07-27T23:33:41 < englishman> And it is next in array
2015-07-27T23:33:56 < Laurenceb__> I'm so confused
2015-07-27T23:33:58 < Lux> but the array is of uin16, so it should jump 2 bytes ?
2015-07-27T23:34:08 < Lux> *uint16
2015-07-27T23:34:08 < Laurenceb__> that was what i thought
2015-07-27T23:34:15 < Laurenceb__> but its jumping by 4
2015-07-27T23:34:25 < Lux> maybe it's that bitbanding stuff ?
2015-07-27T23:34:30 < Lux> or was that something else
2015-07-27T23:34:39 < englishman> O I see
2015-07-27T23:34:54 < englishman> But, the array is to pointer
2015-07-27T23:34:59 < englishman> And pointer is 32bit?
2015-07-27T23:35:20 < englishman> But why does it return 2
2015-07-27T23:35:21 < englishman> Hehe
2015-07-27T23:36:24 < Laurenceb__> now you are confusing me
2015-07-27T23:36:33 < Laurenceb__> surely its a uint16_t array?
2015-07-27T23:44:04 < rkreis> Laurenceb__, i would also expect that to be &f + 2 bytes, not &f + 4 bytes... did you solve the mystery?
2015-07-27T23:44:26 < Laurenceb__> no, maybe i got confused in gdb
2015-07-27T23:44:34 < Laurenceb__> I'll try again tomorrow
2015-07-27T23:46:35 < rkreis> Laurenceb__, http://coliru.stacked-crooked.com/a/9a44952fcd391329
2015-07-27T23:47:51 < Laurenceb__> ah that solves that then lol
2015-07-27T23:47:56 < Laurenceb__> thanks
2015-07-27T23:48:55 < Laurenceb__> oh i know
2015-07-27T23:49:05 < Laurenceb__> I was debugging optimised code
2015-07-27T23:49:17 < Laurenceb__> maybe the second byte wasnt loaded at my breakpoint
2015-07-27T23:49:54 < Laurenceb__> it _seems_ to run fine now, but i dont have debugger
2015-07-27T23:49:55 < rkreis> debugging optimised code? that's a bit like driving a disassembled car :)
2015-07-27T23:50:09 < Laurenceb__> 16 bits of missing float should break it pretty badly
2015-07-27T23:50:18 < GargantuaSauce> except cars aren't made of undefined behaviour
2015-07-27T23:51:13 < rkreis> actually, they kind of are when they tell you what not to do, but not what'd happen
2015-07-27T23:51:26 < rkreis> (the manuals/instructors, well, and nowadays the cars, too)
2015-07-27T23:51:28 < Laurenceb__> now i just have to work out why there is a massive delay somewher ein my code
2015-07-27T23:51:55 < rkreis> [insert delay loop thedailywtf article link here]
2015-07-27T23:53:14 < Laurenceb__> oh its elm-chan trolling me again

2015-07-28T04:11:12 < karlp> tossing up whether to get a "fancy" f1 board with usb, or a bare bare minimum f1 with usb, like this: http://www.aliexpress.com/item/STM32F103C8T6-ARM-STM32-Minimum-System-Development-Board-Module-For-Arduino/32246273606.html

2015-07-28T04:14:49 < dongs> Here's a great infographic about charging your ZANO's batteries!
2015-07-28T04:15:01 < dongs> https://pbs.twimg.com/media/CK69cttWIAAv-C7.jpg
2015-07-28T04:15:07 < dongs> why does everything zano release is "great"
2015-07-28T04:15:53 < dongs> that graphic looks like shit
2015-07-28T04:15:59 < dongs> cant fucking read anything
2015-07-28T04:16:10 < dongs> light gray on gray and retarded resolution
2015-07-28T04:17:48 < dongs> "soon"
2015-07-28T04:19:26 < dongs> thats what completely fucking makes no sense
2015-07-28T04:19:45 < dongs> they shoulda ran with cash long time ago

2015-07-28T04:21:09 < dongs> maybe their strategy is to deliver shit thats completely useless (but was cheap enough to make for them), then declare no refunds cuz they ran out of money making them, and then disappear
2015-07-28T04:21:23 < dongs> i suppose if they pull it off carefully and cheaply using chink parts maybe they can pocket like 50%+
2015-07-28T04:22:08 < dongs> but again, why go through the motions.
2015-07-28T04:23:38 < dongs> no thats dumb
2015-07-28T04:23:43 < dongs> anyone can go to thier shitty office and confirm it
2015-07-28T04:28:28 < mtbg> karlp: it was on some other seller's offer, probably http://www.aliexpress.com/item/STM32F103RBT6-development-board-with-2-8-TFT-USB-cable-Tutorial-CD-for-development-free-shipping/32254866101.html

2015-07-28T05:24:46 < zyp> hmm, that looks nice
2015-07-28T05:26:04 < dongs> they're with like square peg thing

2015-07-28T10:02:57 < talsit> yep
2015-07-28T10:03:27 < dongs> rising yes
2015-07-28T10:03:34 < talsit> cheers
2015-07-28T10:31:16 < talsit> hey dongs, when BOOT0=1 & BOOT1=0, it goes to the embedded bootloader, and you can use ST's flash thingy, do you know if it requires full duplex USART communication?
2015-07-28T10:31:48 < talsit> i would most definitely imagine so
2015-07-28T10:31:58 < dongs> define fullduplex?
2015-07-28T10:32:16 < dongs> i have flash jigs that program 6 to 10 STM32s at once
2015-07-28T10:32:20 < talsit> uses RX & TX
2015-07-28T10:32:22 < dongs> with only TX pin connected to one
2015-07-28T10:32:32 < dongs> and RX to teh rest
2015-07-28T10:32:34 < talsit> yeah, maybe not full duplex, that's not what i'm asking
2015-07-28T10:32:36 < dongs> or wahtever, you get the idea
2015-07-28T10:32:44 < talsit> yep, yep
2015-07-28T10:32:52 < talsit> cheers
2015-07-28T10:32:57 < dongs> works good
2015-07-28T10:32:58 < talsit> i gotta swap usarts around now
2015-07-28T10:33:14 < dongs> if you plan to bootloader you should probbly stick to usart1
2015-07-28T10:33:48 < talsit> yeah, i have usart1 hooked up to a rs485 thingy, but usart2 to a header
2015-07-28T10:33:52 < talsit> so, i'm gonna swap them
2015-07-28T10:34:04 < dongs> this is F1?
2015-07-28T10:34:08 < talsit> yep
2015-07-28T10:34:13 < dongs> right, then you gotta.
2015-07-28T10:34:15 < talsit> 103
2015-07-28T10:34:21 < dongs> F3/F4 have some other uarts that check for BL signal
2015-07-28T10:34:25 < dongs> but on F1 its only 1st one
2015-07-28T10:34:39 < talsit> yeah, ahd the F1 XL range also checks usart2
2015-07-28T10:35:04 < talsit> but whatever, i'm using f103

2015-07-28T14:55:58 < jubatus> wouldn't that be a OS/api question rather than a FS question ?
2015-07-28T14:56:16 < Laurenceb> fatfs
2015-07-28T14:56:25 < Laurenceb> http://elm-chan.org/fsw/ff/
2015-07-28T14:56:53 < jubatus> ah

2015-07-28T15:00:18 < jubatus> unlink ?
2015-07-28T15:00:39 < Laurenceb> yeah but it needs a string argument
2015-07-28T15:01:43 < Laurenceb> hmm maybe i can fix this problem with rename
2015-07-28T15:01:52 < jubatus> maybe you can't delete a file with a handle because a file can have multiple handles and fatfs has no way to invalidate the other handles ?
2015-07-28T15:01:56 < Laurenceb> or a bash script lol
2015-07-28T15:02:03 < Laurenceb> yeah
2015-07-28T15:02:27 < jubatus> but then that should work in the normal unix way
2015-07-28T15:02:33 < jubatus> unlink until the last handle is closed
2015-07-28T15:02:40 < jubatus> maybe too complex for fatfs

2015-07-28T15:42:13 < jpa-> it probably relies on human body having enough capacitance to the ground.. so once you try it on battery operation, performance may be quite poor :)

2015-07-28T16:00:56 < decimad> Laurenceb what's the problem with state |= 80 ?
2015-07-28T16:01:05 < Laurenceb> its setting bit flags
2015-07-28T16:01:16 < jpa-> and writing them in decimal
2015-07-28T16:01:33 < decimad> Well, maybe that's the states' pattern ;)
2015-07-28T16:01:36 < jpa-> should be    state |= STATE_FOO | STATE_BAR;  atleast..
2015-07-28T16:01:46 < decimad> I was thinking maybe |= 0x80 was intended, but hey
2015-07-28T16:01:56 < decimad> I like to_state<MyState> way better ;)
2015-07-28T16:02:15 < jpa-> comment indicates that 80 in decimal is correct :P
2015-07-28T16:02:21 < karlp> that's because you think everything looks better iwth <> in it decimad  :)
2015-07-28T16:02:49 < decimad> karlp hehe
2015-07-28T16:03:20 < decimad> karlp it's just that with <> you can remove any possibility for a bug and create self-documenting code... no |= 80 possible ;)
2015-07-28T16:03:43 < karlp> yes yes, the kool aid tastes wonderful.
2015-07-28T16:03:45 < jpa-> "remove any possibility for a bug"   yeah, right :D
2015-07-28T16:04:01 < decimad> karlp also with <> you can do in place state memory sharing... no need for unions or whatever ;)
2015-07-28T16:04:25 < karlp> when in doubt, add more templates, it will make it "better" ?
2015-07-28T16:04:43 < decimad> no always, only if done well :)
2015-07-28T16:05:11 < karlp> it's an application specific state machine, why would it even need templates? why not just concrete class?
2015-07-28T16:05:17 < karlp> easier on the eyballs and all that...
2015-07-28T16:06:10 < decimad> karlp it's not the application that makes templates necessary, it the general work "state machine", which makes templates reasonable... because in another application you might need a different state machine
2015-07-28T16:06:36 < karlp> yes, and you're the sort of person who thinks it's "less work" to do it with templates :)
2015-07-28T16:06:45 < decimad> no
2015-07-28T16:06:46 < jpa-> what reusable part is there to state machines?
2015-07-28T16:07:06 < karlp> jpa-: don't think like that, <>more better! ;)
2015-07-28T16:07:10 < decimad> jpa- State transition, the enums or switch/case stuff and all
2015-07-28T16:07:40 < jpa-> wouldn't all those things be specific to a single state machine instance?
2015-07-28T16:07:51 < jpa-> ok, well the switch case you can probably "tidy up" a bit
2015-07-28T16:09:21 < decimad> jpa- well, that way you can represent a state by an object and access/transition states by their TYPE, no state identifiers, no enums. Also the template can store the objects in a shared region, so no unions necessary.
2015-07-28T16:09:52 < decimad> in fact, unions are not possible except for trivial types... so it's the only way ;)
2015-07-28T16:10:07 < jpa-> hm, what is this union stuff?
2015-07-28T16:10:16 < dongs> wat about it
2015-07-28T16:10:28 < dongs> oh is this some pb crap
2015-07-28T16:10:29 < jpa-> i mean, why'd you use unions with state machines?
2015-07-28T16:10:44 < jpa-> whereas enum vs. type, i don't see much benefit to go with types
2015-07-28T16:11:03 < jpa-> i think this is just about bashing C++
2015-07-28T16:11:08 < jpa-> come join us
2015-07-28T16:11:22 < decimad> jpa- to share the memory for states' variables... considering you're only ever in a single state only
2015-07-28T16:11:56 < jpa-> decimad: hm, yeah, maybe there is some point in that
2015-07-28T16:12:06 < jpa-> i've never bothered as it's been just a few bytes anyway

2015-07-28T16:12:53 < decimad> that's what I'm talking about... I don't use templates for their own sake, I use them to solve a problem once, and then not worry about anymore
2015-07-28T16:14:08 < jpa-> i've often seen templates used to solve a problem once, with horrible amount of extra complexity.. and then the next time the problem is slightly different and no-one knows how to tickle the template monster
2015-07-28T16:14:40 < decimad> Also representing a state as an object adds constructor and destructor calls close to the state actions, instead of smearing that stuff over a super-class

2015-07-28T17:03:54 < piezoid> About C++ bashing, have some of you tried Rust/Zinc on bare metal device ?
2015-07-28T17:04:07 < piezoid> Algebraic data types is a better than unions and static polymorphism achieve the same thing that templates but with the supervision of compiler
2015-07-28T17:09:40 < decimad> piezoid I was planning to give it a chance once the ecosystem is in place... :)
2015-07-28T17:10:31 < karlp> piezoid: I tried rust on an openwrt device, it was still in the "meg" size, and you have to toss out half of what looks good in rust before you get smaller binaries
2015-07-28T17:10:34 < karlp> but that was a little while ago
2015-07-28T17:11:14 < karlp> having to write everything in unsafe mode seemd kinda pointless
2015-07-28T17:13:55 < piezoid> The binary size was a problem when I tried (about 1y ago), but it looks promising
2015-07-28T17:15:26 < decimad> piezoid looking at algebraic datatypes: It seems to be just what the templates can achieve. The type matching is what a double displatch would look like
2015-07-28T17:15:57 < decimad> but that was just a short glance at it... maybe there's more to it
2015-07-28T17:17:16 < piezoid> decimad: Sum types can be implemented with tagged unions, products are just C structs
2015-07-28T17:17:51 < decimad> I don't know what tagged unions are... let me look that up
2015-07-28T17:18:07 < decimad> oh okay
2015-07-28T17:18:11 < decimad> it's union + tyoe
2015-07-28T17:18:22 < decimad> well yeah, that's what my templates do
2015-07-28T17:18:36 < decimad> in a sense... but not using the union keywoard obviously
2015-07-28T17:19:12 < decimad> well, then rust has syntactic sugar for it...
2015-07-28T17:23:32 < decimad> oh, I see use for winows 10 with its multiple desktops... maybe... i'm tempted
2015-07-28T17:30:46 < dongs> To those whose impatience has led them to question the Zano, the end is in sight.

2015-07-28T18:07:57 < decimad> back in the old days, uninstalling a program meant deleting some files and changing some registry entries... nowadays it means.... i cannot find a word for it...
2015-07-28T18:08:22 < decimad> it seems to be black magic with a lot of science to it
2015-07-28T18:08:35 < decimad> judging by the amount of work that seems to be necessary
2015-07-28T18:09:07 < zyp> how so?
2015-07-28T18:10:24 < decimad> well, it takes ages... granted, this is on a hdd not ssd... still programs need a minute just to gather what needs to be deleted... and then another minute to delete stuff... how can tha be
2015-07-28T18:10:27 < jpa-> on linux, it is still just removing files :)
2015-07-28T18:11:00 < zyp> isn't it in either case?
2015-07-28T18:11:20 < zyp> probably just a ton of files to remove
2015-07-28T18:11:37 < jpa-> could be, or some heavy bookkeeping
2015-07-28T18:11:53 < jpa-> like MSI does, rolling files back and forth
2015-07-28T18:13:14 < decimad> yep, msi in this case

2015-07-28T18:26:29 < zyp> dongs, I found the trick to get working usb cables for the ipad display
2015-07-28T18:26:45 < zyp> micro to mini usb adapter and charge-rated micro cables
2015-07-28T18:27:46 < zyp> because nobody ever designed a mini usb cable for more than 500mA, but nowadays phones charge at over 2A
2015-07-28T18:29:40 < zyp> heh, backlight brightness really matters a lot
2015-07-28T18:30:00 < zyp> this thing draws 0.35A at lowest brightness, 1.45A at highest

2015-07-28T18:32:07 < jpa-> i still wonder how seeed managed to make 1 ohm end-to-end resistance on the mini usb cables they shipped with dso quad to everyone
2015-07-28T18:32:32 < zyp> haha
2015-07-28T18:32:36 < jpa-> it did slow down the charging a bit :P
2015-07-28T18:33:03 < zyp> but damn I had to search to find that fucking micro to mini adapter
2015-07-28T18:33:31 < Lux> i just used a random 2m mini usb cable and it worked
2015-07-28T18:33:31 < jpa-> also for some reason it caused trouble on windows 7 with the bootloader - but not on other operating systems, and not with the normal usb msc, and switching the cable fixed it
2015-07-28T18:33:43 < zyp> there's like adapters from micro to anything in any electronics store here
2015-07-28T18:34:12 < zyp> like lightning, old iphone, nintendo ds, old jap phone charge standards (multiple), etc…

2015-07-28T18:36:53 < zyp> and I don't know where the fourth went
2015-07-28T18:37:08 < zyp> but I have plenty of decent micro cables
2015-07-28T18:37:08 < Lux> i was lucky then :)
2015-07-28T18:37:32 < Lux> but it's def no china trash
2015-07-28T18:37:33 < zyp> yeah
2015-07-28T18:37:37 < zyp> how long is it?
2015-07-28T18:37:41 < Lux> 2 meters
2015-07-28T18:38:00 < zyp> ok, mine aren't longer
2015-07-28T18:38:09 < zyp> so it's not excessive length either
2015-07-28T18:38:25 < zyp> just too thin conductors I guess
2015-07-28T18:38:54 < Lux> even sais 24awg on the cable

2015-07-29T03:34:32 < Roklobsta> if y'all need a good flash device supplier, I can say their CF cards are really reliable.  Dunno about their other bits - should be good though.

2015-07-29T05:55:42 < dongs> well that is the seller problem
2015-07-29T05:55:44 < Roklobsta> if you open it up it will have a sata to SD card adapter in it with a 2GB card.
2015-07-29T05:56:17 < PeterM> Roklobsta, i dunno what world you're in but that price is pretty much spot on for a 240/256gb ssd

2015-07-29T06:12:17 < PeterM> i like the xx horus until, means if you accidentally select am/pm wrogn you notice
2015-07-29T06:12:55 < zyp> and some day I had to debug an issue on a particular setup, so I got some AT&T build and flashed that
2015-07-29T06:13:12 < zyp> and holy shit there were AT&T anything apps

2015-07-29T06:15:26 < dongs> PeterM: i ahvent looked into just rooting that trash and dumping AT&T junk
2015-07-29T06:15:28 < dongs> but probly should
2015-07-29T06:15:33 < PeterM> do it
2015-07-29T06:15:35 < PeterM> much worth
2015-07-29T06:15:50 < dongs> it was some shady ebay purchase
2015-07-29T06:15:50 < PeterM> zyp whats wrong with lg g2 aside from stock software?
2015-07-29T06:15:56 < dongs> probly stolen from AT&T

2015-07-29T06:16:26 < dongs> what other trash is it "installing"
2015-07-29T06:16:54 < zyp> the one I dicked around with were some Motorola
2015-07-29T06:17:11 < zyp> Atrix 2, IIRC
2015-07-29T06:17:17 < PeterM> it has the best screen to phone size ratio, it had the biggest battery for any phone in its dimensions, its cheap and when it came out it had the same specws as anything else at the same time, and also, i am now very fond of the rear power button.
2015-07-29T06:17:41 < zyp> screen to phone size ratio?
2015-07-29T06:17:41 < PeterM> atrix 2 holy shit thats some tiem ago
2015-07-29T06:17:45 < PeterM> yeah
2015-07-29T06:17:48 < dongs> huh. well 5.1.1 upgrade worked
2015-07-29T06:18:09 < zyp> of course it is, I haven't been working with phones for a couple of years now
2015-07-29T06:20:16 < zyp> I don't get this screen to phone size ratio thing, the screen on my phone is already too close to the edge as it is
2015-07-29T06:21:11 < zyp> when I hold my phone in my right hand and type on it with my thumb, I occasionally trigger the lower right corner of the touchscreen with the base of my thumb
2015-07-29T06:21:15 < zyp> and that shit is annoying
2015-07-29T06:21:30 < Roklobsta> i'm stuck on a CM 7.2 build from 2013.  no patch for me.
2015-07-29T06:21:41 < zyp> idk why anybody would want the screen even closer to the edge
2015-07-29T06:22:10 < Roklobsta> Because marketing says fuck you we want it.
2015-07-29T06:22:25 < zyp> well, now it was PeterM saying it, not marketing
2015-07-29T06:26:09 < dongs> k installing the shit i actually wanted to install
2015-07-29T06:26:15 < dongs> lets see how that works
2015-07-29T06:26:29 < PeterM> zyp i dont mean left right, i mean top bottom

2015-07-29T07:59:07 < zyp> PeterM, I like the no-bullshit aspect of buying a nexus phone, would an oneplus phone be a suitable alternative?
2015-07-29T07:59:39 < PeterM> nah, its a pin in the ass to buy one with the invites system
2015-07-29T07:59:58 < PeterM> and if you dont do the  invite thing you pay much more, so may as well get something else

2015-07-29T08:01:31 < PeterM> no, i wouldn't buy it. i'd get a sony xperia and flash the sony aosp rom

2015-07-29T08:02:27 < PeterM> can buy sony phone but have standard google experience
2015-07-29T08:02:46 < zyp> do sony still use their own bullshit bootloader?
2015-07-29T08:03:18 < PeterM> all phone manufacturers do their own bootloaders, there are no standards
2015-07-29T08:03:33 < PeterM> well, no google appointed standards for android
2015-07-29T08:03:33 < dongs> huh
2015-07-29T08:03:33 < dongs> nice
2015-07-29T08:04:01 < zyp> I thought fastboot were the standard
2015-07-29T08:04:10 < zyp> I think that's what we used on most devboards
2015-07-29T08:04:21 < PeterM> fastboot is jsut an interface
2015-07-29T08:04:40 < zyp> now you're just nitpicking
2015-07-29T08:04:41 < PeterM> and yes, sony phones support fastboot
2015-07-29T08:04:46 < PeterM> no, im not
2015-07-29T08:05:11 < zyp> well, let me rephrase my original question then
2015-07-29T08:05:39 < zyp> «does sony's bootloader still require that horribly dumb host side software?» as to which you've already replied no
2015-07-29T08:06:05 < PeterM> just fastboot + appropriate pc side fastboot driver
2015-07-29T08:07:13 < zyp> oh, wait, when I think about it, that sony devboard I had actually did have a fastboot second stage loader
2015-07-29T08:07:31 < zyp> you just had to run some silly utility first to load that through some proprietary first stage loader
2015-07-29T08:08:15 < zyp> or something like that, it's a few years since I touched that

2015-07-29T09:27:31 < upgrdman> the problem was that they had an ISR config a couple peripherals, and that ISR got called before the init code for those peripherals
2015-07-29T09:28:04 < upgrdman> so for the first interrupt, the ISR would poke registers for disable periphals, which causes a hardfault on this chip
2015-07-29T09:28:15 < upgrdman> but after the first isr call, it would work.
2015-07-29T09:28:47 < upgrdman> i just needed to rearrange the periph init function calls
2015-07-29T09:28:55 < zyp> wat
2015-07-29T09:29:09 < zyp> why is that ISR enabled in the first place?
2015-07-29T09:29:31 < upgrdman> they config'd a timer, and that timer's isr would then poke registers for SSP and ADC

2015-07-29T16:55:52 < zyp> because that's a norwegian word to me
2015-07-29T16:56:52 < dongs> isnt it latin or someshit
2015-07-29T16:57:41 < zyp> idk, it's common in germanic languages
2015-07-29T16:58:01 < zyp> but it's what we call free in norway

2015-07-29T17:44:13 < trepidacious> and twice as many cores as banana pro, I should give it a go

2015-07-30T04:35:11 < upgrdman> if that was the case, i would understand why
2015-07-30T04:35:27 < upgrdman> this is some nxp lpc code i'm fixing
2015-07-30T04:35:35 < dongs> is it a register?
2015-07-30T04:35:45 < dongs> (hardware register)
2015-07-30T04:37:52 < upgrdman> yes
2015-07-30T04:38:02 < upgrdman> and no, the MSbytes are not used
2015-07-30T04:38:29 < upgrdman> only the LSByte is usable, the other 3 are reserved and "should be 0"

2015-07-30T04:43:25 < dongs> there's a reason its done probabyl, but youre losing it when you convert stuff to foo()
2015-07-30T04:45:02 < upgrdman> LPC_SSP0->IMSC = (LPC_SSP0->IMSC & 0x00) | 0x08;
2015-07-30T04:47:03 < dongs> yeah doesnt look like that needs any special thing like that
2015-07-30T04:47:36 < dongs> youre enabling tx interrupt
2015-07-30T04:48:13 < upgrdman> i know
2015-07-30T04:48:24 < dongs> but i duno, i wonder if that makesi t access register as 8bit
2015-07-30T04:48:34 < dongs> im to lazy to look at lpc docs to see how wide it is
2015-07-30T04:48:51 < dongs> hm no that doenst make any difference
2015-07-30T04:48:59 < upgrdman> no need to. bits afters the first byte are all reserved and "should be 0"

2015-07-30T06:51:48 < hesperaux> do you build STM32 stuff on nix?
2015-07-30T06:51:50 < dongs> i'm an avid opensores developer
2015-07-30T06:51:54 < hesperaux> lol
2015-07-30T06:51:55 < dongs> hesperaux: no, i build it in keil
2015-07-30T06:52:01 < hesperaux> ok
2015-07-30T06:52:12 < hesperaux> I'm looking at how I could automate builds with Jenkins and a gerrit code review system
2015-07-30T06:52:21 < dongs> i know how
2015-07-30T06:52:24 < dongs> dont write shitty code
2015-07-30T06:52:34 < dongs> then yo uwon't have to bvuild it each tiem ytou commit
2015-07-30T06:52:37 < hesperaux> I use CoIDE to develop in doze, but it creates its own project format
2015-07-30T06:52:49 < hesperaux> dongs, there are other reasons to use auto builds which I don't want to get into
2015-07-30T06:53:02 < hesperaux> also the solution to automate builds in jenkins is not "don't automate builds in jenkins"
2015-07-30T06:53:34 < zyp> hesperaux, so, uh, you're not familiar with make?
2015-07-30T06:53:46 < hesperaux> never used it, zyp
2015-07-30T06:53:55 < karlp> how did you find jenkins then?
2015-07-30T06:53:58 < zyp> haha
2015-07-30T06:53:59 < dongs> you're fucked then
2015-07-30T06:54:02 < hesperaux> used it in my job
2015-07-30T06:54:05 < zyp> well, make is the classic solution
2015-07-30T06:54:18 < zyp> personally I prefer scons which is a more modern alternative
2015-07-30T06:54:21 < karlp> well, jenkins/hudson projects just have a bit that says, "how to build"
2015-07-30T06:54:25 < karlp> and you can enter any shit you like
2015-07-30T06:54:42 < zyp> but the idea is the same either way
2015-07-30T06:54:44 < karlp> like "make" or "scons" or "my_fucking_cool_shit.sh" or whatever
2015-07-30T06:55:09 < karlp> how did yo uget to th epoint of having gerrit and jenkins and no idea how to build your code?!....
2015-07-30T06:55:39 < karlp> heh, jumbo dev board "everythign ever" is up to almost 600 euros
2015-07-30T06:56:00 < hesperaux> The IDE builds the code, karlp. I am currently trying to aspire to understanding it.
2015-07-30T06:56:26 < zyp> this is the problem of marrying an IDE
2015-07-30T06:56:33 < zyp> you get all dependant on it
2015-07-30T06:56:34 < karlp> yeah, so either a) find out how cocox is actually building it, and use that
2015-07-30T06:56:36 < hesperaux> I will look at scons. Technically, I have used make before, but not enough for me to feel comfortable saying so
2015-07-30T06:56:47 < hesperaux> zyp, yes, it bothers me to be honest
2015-07-30T06:57:31 < zyp> unless you're already familiar with python, you might find it easier to get started with make
2015-07-30T06:57:46 < zyp> there's probably also more resources available on make
2015-07-30T06:57:49 < hesperaux> karlp, coocox is just using the arm compiler and linker. I have the command lines for that, but it enumerates every file in the codebase to gcc, which I would like to do automatically. Their project file lists all the files to be compiled, so I could parse the XML and create a makefile but I didn't know if that was unnecessary extra work (hence my questions here)
2015-07-30T06:58:19 < karlp> coocox is just eclipse isn' tit?
2015-07-30T06:58:29 < hesperaux> sort of. I think they forked it
2015-07-30T06:58:46 < hesperaux> I'm not aware of any way to get the source to coide, either
2015-07-30T07:01:34 < hesperaux> can anyone recommend a good primer on how to compile and link stm32 code on linux "the old fashioned way"?
2015-07-30T07:01:41 < hesperaux> I would like to understand the process better

2015-07-30T10:44:07 < dongs> But let's face it: TQ is not the kind of fancy startup company you often find on kickstarter. They worked on military projects, so sharing a lot with the public is not something that comes natural for them. They don't have professional marketing and design (look at the design of other drones and their websites). BUT they are passionate about what they're doing and they doing it their way. In a few weeks we'll all be a lot smarter.

2015-07-30T15:25:43 < upgrdman> they probably blur the books so when the girl is holding one upside down, you dont laugh at her

2015-07-30T15:45:31 < PeterM> man lp8550 is nice led driver, unfortunately, dsbga
2015-07-30T15:57:27 < karlp> is it common that an fpga needs a "special" flash config storage? like altera epcs4 shit? can't they just generic spi flash?
2015-07-30T15:59:26 < qyx_> hm, aren't those memories different? "bitstream" interface instead of spi
2015-07-30T16:01:28 < jpa-> usually they just use generic spi flash
2015-07-30T16:02:04 < qyx_> at least not the spartan3 i played with
2015-07-30T16:02:13 < qyx_> it had some nor memory programable using jtag
2015-07-30T16:02:45 < jpa-> i guess the difference is exactly that, separate jtag programmability
2015-07-30T16:03:07 < jpa-> otherwise you have to do annoying stuff like program through spi or program a spi-jtag bridge on the fpga
2015-07-30T16:03:21 < jpa-> but most fpgas support normal SPI flash also AFAIK
2015-07-30T16:06:56 < karlp> zyp: nice idea on using a second spi periph...
2015-07-30T16:11:12 < dongs> karlp: not required
2015-07-30T16:11:31 < dongs> most vendors will wanna sell you their own config flash shit but regular spi stuff works too
2015-07-30T16:11:37 < dongs> with some limitations
2015-07-30T16:12:14 < jpa-> usually if you have a microcontroller, it is nicer to load from that anyway

2015-07-30T16:17:05 < karlp> why are we looking at afrikans wikipedia?
2015-07-30T16:17:20 < claude> hmm ice40 have an otp Memory Region for the bitstream
2015-07-30T16:18:11 < karlp> hope it's not otp!
2015-07-30T16:18:45 < claude> it's otp
2015-07-30T16:20:03 < claude> but you can still 'boot' the ice40 from an external spi Flash/jtag/micro afterwards (just in case your RTL isn't right the first time *cough* ;) )
2015-07-30T16:20:03 < jpa-> yeah, you can either load to RAM many times, or once to OTP
2015-07-30T16:21:40 < claude> or altera max 10 , marketed as cpld but internally it's more like an fpga with nvm Memory for configuration
2015-07-30T16:22:28 < claude> too bad the ice40 stop at 8kLE ...
2015-07-30T16:23:19 < karlp> I don't have any idea what I'm doing anyway, just thought it was cheap and also cheap to buy the parts themselves.
2015-07-30T16:23:28 < claude> :)
2015-07-30T16:23:48 < jpa-> i wonder if lattice is going to develop the ice40 series further, or if they'll just slowly kill it
2015-07-30T16:23:49 < claude> avr core and arduino ide ! ;)
2015-07-30T16:24:50 < claude> yeah interesting question , also lattice just bought the ice40 (and ice65) line when they aqquired Silicon blue some time ago

2015-07-30T16:25:21 < karlp> I saw some silicon blue name on some board I was looking at last night
2015-07-30T16:25:47 < karlp> machx02 seems to be almost as cheap, but they've been promotiing the ice40 series for a while now.
2015-07-30T16:25:54 < claude> these chinese pocket quad dso for 100$ have an siliconblue ice65 as fpga
2015-07-30T16:25:55  * karlp doesn't know shit
2015-07-30T16:26:31 < claude> yes the old ice40 devboards from lattice are still with siliconblue in the silkscreen

2015-07-30T19:49:08 < qyx_> Getty: how can your fully deterministic embedded system crash under load?
2015-07-30T19:49:32 < Getty> its not the load, its all memory
2015-07-30T19:49:51 < Getty> lwipopts.h is not trivial or lets say: it can seem good but it isnt ;-)
2015-07-30T19:50:20 < Getty> i also have probably still 1-2 error situations i dont handle proper, but right now i see that alone with tuning of the memory of lwipopts.h i can make them all disappear
2015-07-30T19:51:18 < Getty> oh and firefox is a bastard about cascaded loading
2015-07-30T19:52:56 < qyx_> what
2015-07-30T19:53:04 < qyx_> you can always process your request fully serially
2015-07-30T19:54:20 < qyx_> you do not have to accept client's connections immediately
2015-07-30T19:54:39 < Getty> well i thought i had a good level as it worked with chrome together with 2 parallel floods ;)
2015-07-30T19:54:52 < Getty> you must admit if you test that way, you can assume its fine what you do ;)
2015-07-30T19:55:03 < Getty> but no idea what firefox does, it makes too much but that was then the failure of my config
2015-07-30T19:55:11 < Getty> thats what i tuned now massivly in lwipopts.h
2015-07-30T19:55:32 < qyx_> that could also mean that chrome is not able to parallelize its requests properly

2015-07-31T04:29:21 < karlp> yeah, not sure what I was doing, just had another aricle open, realized it was going nowhere useful or informative, and closed the tab with great prejudice.
2015-07-31T04:30:03 < karlp> was eating cheese and sausgage, not feeling up to "serious work" thought a litttle bit of web surfing never hurt anyone :)

2015-07-31T04:34:18 < emeb_mac> cheese and sausage. yum.
2015-07-31T04:37:09 < karlp> yup, went and got some more.
2015-07-31T04:38:14 < karlp> only got abou 60 songs left from sxsw 2014 to listen to for the first time, and 61 pull requests open.  match made in heaven right?
2015-07-31T04:39:54 < Getty> ok, now its stable... at least i cant crash it anymore... puh... but that was a fizzling, i am now still doing 2 parallel, cause 1 is doing more problem on the loading front (even tho i keep a wait loop for the unanswered ones)
2015-07-31T04:40:23 < Getty> but very important was to try anyting to reduce the send buffer, as thats like else buffer for the buffer for the buffer in the buffer multiplication if its high ;)
2015-07-31T04:40:37 < Getty> i think in the worst moment the send buffer is 4 times in RAM
2015-07-31T04:41:31 < Getty> yeah no probably not, as the lwip double usage and the prepare double buffer might be not at the same time, but it is brutal ... that was killing most often my ram
2015-07-31T04:41:43 < zhanx> so no simulators for linux i take?
2015-07-31T04:42:07 < Getty> but best is still the irony that by giving the network more ram, i highered the chance of the crash as it was about the left memory and the heap hehe
2015-07-31T04:47:07 < dongs> Have you ever wanted a larger dev board in physical size only? How about slow processing speeds? spend more money? If you answered yes to any of the following, have we got a deal for you!

2015-07-31T05:00:05 < aandrew> some are pretty slick, a lot are shit, but it beats reading slashdot or some other site
2015-07-31T05:00:51 < dongs> uh for example?
2015-07-31T05:01:03 < dongs> all i ever seen on tehre was either adverts for shit i dont need or just dumb crap
2015-07-31T05:01:22 < aandrew> how about http://tim.jagenberg.info/2015/01/18/low-power-esp8266/
2015-07-31T05:01:30 < aandrew> or http://kylegabriel.com/projects/2015/04/mushroom-cultivation-revisited.html
2015-07-31T05:02:12 < aandrew> those two are sitting in browser tabs for a good month or so now
2015-07-31T05:02:13 < dongs> 1st link: closed after seeing fritzing
2015-07-31T05:02:17 < dongs> 2nd link, im not a stoner
2015-07-31T05:02:21 < aandrew> but you see
2015-07-31T05:02:27 < aandrew> you write it off after a casual glance
2015-07-31T05:02:53 < aandrew> who gives a shit about fritzing? the link explains about getting super low power consumption out of it. Fritzing is shit, agreed but look beyond the shit
2015-07-31T05:03:08 < aandrew> and second: there are lots of reasons to grow your own mushrooms and not the magic type
2015-07-31T05:03:16 < dongs> its useless for production
2015-07-31T05:03:22 < dongs> who the fuck is going to sit and bluewire some pins
2015-07-31T05:03:23 < aandrew> I have some links for hydroponics as well, again not for stoner use
2015-07-31T05:03:24 < dongs> on production boards
2015-07-31T05:03:28 < aandrew> dongs: not about that
2015-07-31T05:03:31 < dongs> then what
2015-07-31T05:03:46 < aandrew> I've developed an esp8266 board of my own, taking some of those ideas from that page and adapting it for my own use
2015-07-31T05:03:49 < aandrew> zero bluewire
2015-07-31T05:04:18 < dongs> i just use $3 china "fcc certified" module
2015-07-31T05:04:24 < dongs> works for me
2015-07-31T05:04:26 < aandrew> sure there's that too
2015-07-31T05:04:56 < aandrew> anyway I make a lot of good money from having a lot of weirdass ideas often poorly implemented in the bacck of my head that i can pull out and sell to someone for $$
2015-07-31T05:04:57 < dongs> then next question is how many of yours did you sell and how much will it be per board?
2015-07-31T05:05:14 < dongs> mine will be something liek $1k/board and I could potentially sell one to each tv station in japan
2015-07-31T05:05:22 < aandrew> the board's still at prototype stage, might never get beyond that
2015-07-31T05:05:34 < dongs> tv station = tv transmitter station that is
2015-07-31T05:05:43 < aandrew> but again, it's the idea, not the specific implementation that is important
2015-07-31T05:05:46 < dongs> which there's a few 100s of
2015-07-31T05:05:51 < aandrew> dongs: I understand what you're saying
2015-07-31T05:06:08 < aandrew> and again, your use case probably has zero fucks given about ultralow power consumption which is fine
2015-07-31T05:06:10 < dongs> anyway hackaday is shit
2015-07-31T05:06:16 < dongs> thats what im saying
2015-07-31T05:06:23 < aandrew> many uses don't need that kind of thing

2015-07-31T05:16:22 < aandrew> about chrome? yeah
2015-07-31T05:16:27 < dongs> they fucking added taht dumb user button thing in taskbar again

2015-07-31T05:16:52 < aandrew> must be because I'm not on windows

2015-07-31T05:29:27 < aandrew> looked at it, very difficult for me to grok even compared to C# which seems easier for me to pick up
2015-07-31T05:29:47 < aandrew> CLI is important for me, but everyone's got their own style
2015-07-31T05:30:13 < dongs> i prefer a working file manager
2015-07-31T05:31:33 < aandrew> I don't often use it. CLI. :-)
2015-07-31T05:31:54 < aandrew> but yes Finder has a few things that drive me nuts, but so does exploder.exe
2015-07-31T05:31:55 < dongs> yeah please pick out ~10 images out of ~100 in a folder with cli and move them to another place
2015-07-31T05:32:15 < aandrew> not something I do often
2015-07-31T05:32:27 < aandrew> I can cherry pick things that are easier in CLI too. that's a useless excercise

2015-07-31T07:40:51 < jpa-> for inline functions extern does have a meaning, though - not an intuitive one though :D
2015-07-31T07:41:30 < upgrdman> meaning?

2015-07-31T07:48:19 < upgrdman> jpa-, what is the unintuitive meaning of extern for an inline function?
2015-07-31T07:49:06 < jpa-> upgrdman: depends on standard version, but in C99 it is something like "always make one externally visible instance of this function, but inline it also if you can"
2015-07-31T07:49:45 < jpa-> very rarely needed :P

2015-07-31T08:26:13 < upgrdman> if there is a foo() but every call to it is if(!foo()) ... is there any good reason not to redo the function as not_foo() ?

2015-07-31T08:26:53 < dongs> there's no reason to redo it

2015-07-31T13:16:40 < jubatus> do stm32fxxx parts have a LCD controller ?
2015-07-31T13:16:53 < jubatus> can you drive this: http://www.goodluckbuy.com/wildfire-3-2-inch-tft-lcd-touch-screen-with-stm32-code-240xrgbx320-.html directly from an STM32 or do you need a controller chip ?
2015-07-31T13:16:53 < dongs> some f4, l1 parts do
2015-07-31T13:16:57 < dongs> depending on waht you mean by lcd
2015-07-31T13:17:14 < dongs> you dont need alcd controller for that.
2015-07-31T13:17:18 < dongs> those can be either parallel or SPI
2015-07-31T13:17:41 < jubatus> I don't see any chip on the pcb (only the touchscreen controller). is there a chip on the glass ?
2015-07-31T13:17:56 < dongs> https://www.youtube.com/watch?v=4gwAFDoSIsU

2015-07-31T13:18:12 < dongs> i did thise thing with a random SPI lcd
