STM32 (RAK3172) and WS2816C-1313 problems #410

Closed Jan-OleGiebel closed 1 week ago

Jan-OleGiebel commented 2 weeks ago

Hi! I'm currently struggling with getting WS2816C-1313 neopixels to work with a STM32WL (RAK3172). When specifying the correct numer of pixels (16) only 8 light up and only turn on with the color white, no other color works. Sometimes the last LED turns green. When I set the number of LEDs to 32 all light up. However they flicker and I'm unable to set any color. I've tried different speeds, etc. But nothing seems to fix the issue. Do you have any suggestions, how I can get the LEDs working?

Thanks a lot!

I will close this, as I wrote my own driver based on this library, you can find it here, if you also want to control WS2816 Neopixels. https://github.com/Jan-OleGiebel/LoRaWAN-LED-Christmastree
