GPIO Pin 18

Open sean-smith opened this issue 1 year ago • 1 comments

Looking at the code it looks like you use GPIO 18 pin. Do you have to use that? can you use any GPIO pin?

Reason I'm asking is I want to make a wiring harness to quickly connect the WS2811 lights and it would be nice if all the pins were next to each other.

Looking at https://pinout.xyz/pinout/unicorn_hat it looks like GPIO 18 supports PWM0. Is that the reason?

Update I found the answer on the adafruit neopixels wiring tutorial:

NeoPixels must be connected to GPIO10, GPIO12, GPIO18 or GPIO21 to work! GPIO18 is the standard pin.
