I do not argue :) I have not driven more than 16 pixels and have not used the i2s version

These look promising AO3402
loving the SMD stuff... much cheaper than through hole

thanks for the advice. i'll order some and get back to you... in 6 weeks!

@igrr the full support for coroutines seems to be getting a bit more complicated. There are two spots that don't get an argument for a callback which will just add a limitation on the user but the TCP stack calls for two sources of wakeup, the data callback and a timeout callback which complicates things. I'll still think about it but I'm getting less convinced it's worth it.

@me-no-dev Yeah, NeoPixel models and "generations" have differing tolerances. The same chip but purchased six months apart may work well at 3.3v. BUT, the spec on most of them is 3.8v - 5.4v; so 3.3v is out of spec. The problem is that they don't fail, they just act strange (flashing, some pixels fail to light, colors are off).

Say I want to build a very simple PCB based on this board (http://www.wemos.cc/Products/protoboard_shield.html) what would I need to e.g. send it to OSH Park and get some boards? Do I really have to learn Eagle or would Fritzing work too? It would only need like 4 traces.

@me-no-dev
@Makuna wow :) did not know and expect that...

It looks like SPIFF is broken on one of my Wemos D1 minis. I can't upload any spiff data.

warning: espcomm_send_command: didn't receive command response
warning: espcomm_send_command(FLASH_DOWNLOAD_BEGIN) failed
closing bootloader
error: espcomm_upload_mem failed

But uploading a new programm is working fine... using latest platformio

@FWeinb
Even OTA Spiff upload is broken on 50%

Hi!

Hi, is there a way to compile these library for an esp8266? https://github.com/dailab/libsml
I've tried it one time and its struggeling by searching for uuid.

@mozgy
@FWeinb eagle or kicad is very easy to learn ..
Stavros Korokithakis
@skorokithakis
@FWeinb i pretty much would recommend learning kicad for that
but i love kicad
although i'm not sure why you need that board, if you're making your own pcb

Hello, anyone know if IGRR or MeNoDev are around? I was asked to post a stack trace from the 8266 occurring when a multicast session is attempted. Not exactly sure where to post the stack trace here....

@me-no-dev
I am around, but this seems more in @igrr 's ballpark. He is playing with gcc on windows and your trace points there.
Martin Ayotte
@martinayotte
BTW, @Tinker1 , @IGRR and @me-no-dev , it seems that this stacktrace has been seen a lot by different users trying to do UDP Multicast. I've asked many users to provide stacktrace on the forum, and it always look similar. This seems to have been introduced in 2.2.0 ...
Me No Dev
@me-no-dev
@martinayotte have you noticed it to be windows related?
Martin Ayotte
@martinayotte
@me-no-dev , I didn't faced the issue personally, since I'm not using UDP. I've just testimony what several threads figured out when I was asking users to provide decoded stacktraces ...
Ivan Grokhotkov
@igrr
@Tinker1 @martinayotte @me-no-dev This is the same as #1826. It will be resolved once we make the switch to gcc-built LwIP (#1926)
Not a Windows-specific issue btw (see this comment — same crash, but on Linux)
I'll try to find some time to push these changes today. Been preoccupied with libstdc++ on the ESP32, but hopefully will finish that stuff today.
Martin Ayotte
@martinayotte
@igrr , Oh ! ESP32 ! does someone gently gave you his own ESP31 Beta or is that Espressif feel that it is time to start shipping newer ESP32 ? :-)
Ivan Grokhotkov
@igrr
(disclosure) i now work at Espressif
Martin Ayotte
@martinayotte
Congrat ! :-) ... But still at St-Peterbourgs, or did you move in Far East ? Did you meet Sprite_tm ?
Ivan Grokhotkov
@igrr
Sprite_tm sits right across my desk :)
Martin Ayotte
@martinayotte
(I was suspecting that when you announce License switch)
Is Sprite_tm is at St-Peterbourg too, or both of you moved in China ?
Ivan Grokhotkov
@igrr
as far as libstdc++ is concerned, the difference between the 31 and 32 is mostly non-existent. So should work on 31's as well.
No, we're both in Shanghai
Martin Ayotte
@martinayotte
So, big changes in your meals :-)
Ivan Grokhotkov
@igrr
Mmm, yeah, probably the most difficult part :)
Martin Ayotte
@martinayotte
...and vodka ? no, there must be some substitutes ... ;-)
BTW, do you will Officially disclose this announcement on the Forum ? (ie.: probably under Richard "ESP Heros" thread)
Ivan Grokhotkov
@igrr
Never liked vodka, so can not really complain about that :)
Martin Ayotte
@martinayotte
Then, Poire William or Prunelle ? (those are my best) ;-)
(on another subject : you probably remember Squonk, we didn't got any news from him since awhile. Are you in touch with him ?)
Ivan Grokhotkov
@igrr
No, i haven't been in touch with him. I assumed he drifted off into some other new and interesting area.
Martin Ayotte
@martinayotte
He is been leading the engineering for the Domino.io, so he had moved to China too, from France, but after Kickstarter campaign finished, no more public apparence ...
(Not true in fact, he subscribed to ESP32 forum, and posted 1 or 2 times, then silence ! I hope he is going well ...)
Michael Miller
@Makuna
@igrr so now my joke about hiring better devs is no joke, they did 😆
Ivan Grokhotkov
@igrr
To which I replied, half-jokingly, that if you'd like to switch jobs, then hiring a better developer can be arranged)
Michael Miller
@Makuna
@igrr I contract, I don't work for anyone.
TheAustrian
@TheAustrian
I have a question: will there be some convenient wrapping function for light sleep now that there is some wakeup callback function support in the latest SDK? I can't really seem to get it to work directly, so anything that makes sleep easier would be appreciated. ;)
Lars Englund
@larsenglund
@igrr congrats to your new position!
