Hi guys. Im new here and im testing my WS2811 led matrix arduino code with PlatformIO. Im able to upload and build the code but it just doesn't seem to work. I still get the messages from serial as should, but the leds just wont turn on. I have made code using FastLED libraries and it's working just fine when using Arduino IDE. Anyway if i try to make just some simple led blink code (not using FastLED) using PlatformIO, it seems to work just as expected. I tested also some FastLED example projects and they doesn't seem to work if built and uploaded them with PlatformIO, but they works if i use the Arduino IDE. Im out of ideas what could be causing this issue.
Any ideas could be nice, as looks like the PlatformIO woul be a really good IDE for Arduino otherwise.
