Bloody posted:do that last one, they're all going to have exciting rare bugs anyways yeah, probably going to go with: https://github.com/pellepl/spiffs also this is cool: https://github.com/x3ro/coffee-fs except it has the hilarious limitation that any 0x00 bytes at the end of the file get dropped when you close it and open it again

Spatial posted:what's the write endurance like on tsmc 40nm embedded flash? Hopefully at least as much as the spec on the data sheet? MLC or SLC?

I guess even a cheap external sdram with an m4 would blow the bom?

hobbesmaster posted:eclipse is ok, there's ARM gcc and openocd plugins that work as well as any other embedded tool chain (that is to say, finicky) http://gnuarmeclipse.github.io Yeah the eclipse/GCC toolchain is pretty great. Also grab the drivers from the STMCube, they seem to work just fine

the forums at realworldtech used to be real good, neckbeards having flamewars about poo poo like how wide an instruction decoder should be and poo poo like that. you could learn a lot But recently they've been getting trolled by idiots and white noise posting and it's become almost unreadable. Are there other places where discussions like that happen?

Sure, there will always be the guys who decide that this one weird architecture developed at a university in the 70s is the one true way to do computing. Parts of their arguments, and refutations of their points, are often interesting. But now there are a couple of posters that honestly may just be Markov chain bots.

the dev kit for the chip didn't terminate their sdram bus so we figured it would be fine to not to terminate ours the ringing is past the absolute max limits for the pin voltages

yeah openocd has been surprisingly stable for me the only annoying bit is that every so often the breakpoints will seem randomly jump around by a few lines. i assume whatever adjusts their position in eclipse when you add/remove lines just fucks up sometimes maybe anyway, came here to post this (warning: reddit but it's a good post) : https://www.reddit.com/r/hardware/comments/621sd4/intels_10_nm_process_during_todays_intels/ intel is still real good at fabbing chips, at least their CPUs anyway

do people in this thread know about hotchipsvideos? you should know about hotchipsvideos https://www.youtube.com/user/hotchipsvideos also I enjoyed a couple of articles from everyone's favourite occasionally insightful raving lunatic: http://semiaccurate.com/2017/03/19/intel-officially-introduces-xpoint-dc-p4800x-ssd/ http://semiaccurate.com/2017/04/04/intels-hyperscaling-is/

I may have found the problem causing the power supplies we're using to occasionally explode, so now I'm running a test to try and replicate it and knowing that it may explode at any time and I'll have to run over and kill the test is making me nervous.

Sagebrush posted:yeah but why would you This except unironically because the chip fast enough to run a garbage collected language will cost 10c to make and use milliwatts

$1 for 128kbit is pretty pricey tho

are there fancy scopes that allow you to basically script a trigger? like "if data bus 1 value is 0xABCD and then within 20us there is a low pulse on analog line 1 lasting less than 10ns, wait 100ns and trigger" i mean it's academic because we can't afford anything like that

spent a couple of hours checking the continuity of an improvised wire harness and trying to debug a chip I couldn't talk to over SPI until my coworker thought to ask "are you sure you're connecting to the right SPI bus?" I was not

if you're using an stm32 just use the cube. if you hate the little configurator, it drops all the drivers in a folder you can just copy out of if you want
