I tried the FastLED blink example (that tries to turn on and off the 1st LED on ws2812b) on the Xiao but the LED was not blinking. The same circuit setup and program works on an Arduino uno. Any idea? Thanks.
Setup like this:
- Xiao pin D3 as data pin connected to DIn on the ws2812b with a 330ohm resister in between.
- Xiao connected to PC thru type-c USB.
- ws2812b 5V power by an external power supply.
