I’m just trying to run drive some APA102 pixels with an ESP-01. Can I check with someone that I set the Data Pin as 0 and the Clock Pin as 2 to use the two GPIO pins on the ESP-01?
FastLED has only been tested with the esp8266 arduino core - which doesn’t list an ESP-01 as a supported target board - so, while it might be possible to do - it’s unlikely that it’s been tested at all (I know I haven’t).
I think I’ve had it running before with the ESP-01 but I’m not 100% sure! I’ll try it out tomorrow and post how I get on.
