WebJan 28, 2024 · One of the things that the FastLED library will do is attempt to use the fastest mechanism available to it for driving your leds. This stands out most clearly with SPI based chipsets (e.g. the APA102, WS2801, etc...). When you set up your leds, you give FastLED a data pin and a clock pin: FastLED.addLeds (leds,NUM_LEDS);

As long as those interrupt handlers don't take more than 5µs to run, everything will be happy. As long as your interrupt handlers don't need to run more frequently than once every 30µs, that is.
