Topic: FastLED on ESP32
Hello,
I'm using RemoteXY for the first time and so far things have been working great but I'm having an issue with using it with FastLED library. It seems that every time the RemoteXY_Handler is called, the lights all switch off.
As part of my troubleshooting, I tried using the regular delay rather than RemoteXY_delay then they will stay on for the duration and when the loop goes back to call the handler, it seems to cause problems.
I also tried a few different GPIO pins in case that would be an issue but it seems to be the same on all the pins I have tried so far.
I'm confident the code to control the lights is good as I have tested it without remotexy and everything seems to be working ok but if I have missed anything, please let me know.
Could anyone suggest why this may be happening please? Thanks in advance
