Hi all,
I’m working on a project using TinyPico’s with WLED. Eventually I’ll attach some strips, but for starters I wanted to get WLED working with the built-in APA102 LED.
It’s documented as using pin 2 for data, pin 12 for clock, and pin 13 to control a high side switch feeding the APA102 power.
However, using these pins with WLED the best I can achieve is a single solid color. It only seems to turn on every 4th time I toggle the power, and it always remains the same color, refusing to update from any input for brightness, color, or effect changes.
I’m using the APA102 LED type, and using the relay setting to pull GPIO 13 high. I’ve tested with the relay setting inverted and not.
To confirm this isn’t a hardware issue, I’ve run the example Arduino sketch and confirmed the LED works correctly with the example SWSPI bit-banging.
I’m a little stumped. Has anyone tinkered with WLED on this device and used the built-in APA102 LED? Perhaps I’m missing something simple.
Thanks,
Roro
