Open iv-mexx opened 1 year ago
I once had that problem too and found it was a short circuit between 5V and 3.3V (soldering mistake). The Pi seemed to work perfect in the first place but always crashed when opening the ws2812svr. Later I found out some other stuff wasn't working anymore, SD card was very hot and then noticed the solder problem.
This might be a total different problem... What you can do is try using a different DMA channel but be careful as this may corrupt the SD card or do unexpected things.
Try if this library works: https://github.com/jgarff/rpi_ws281x which the ws2812svr is based on.
Hello We have the same issue with a Pi Zero 2W with the latest Raspbian image from the raspberry pi website. As soon as we do an "init" after "setup 1,20", the system hangs We triplechecked the connections - no short circuit on the board Any ideas? Kind regards --Thomas
@tstalzer I was never able to resolve this, but I have since tried with multiple other Raspberry Pi Zero 2W and all of them had this issue. Paradoxically, I was also not able to find any older Raspbian image where it's working even though I know it was working before upgrading a day before opening this issue...
I know I've had the issue myself but didn't have time to investigate yet sorry, maybe someone can find it and make a pull request?
Hi there, right away I'm sorry for probably being too vague but I dont know how to get more useful information...
Everything worked fine until yesterday when I ran
apt upgrade
on my Raspberry Pi Zero 2 W. After that, as soon asinit
is called inws2812svr
, the Pi freezes and gets really hot. I'm only connected via SSH and at that moment the SSH connection breaks, so I dont know how to get any more information...When I put the same SD card into my older Raspberry Pi Zero 1, everything still works as expected....
