Hi,
after making my first experience with the Unicorn Hat on a Raspberry Pi 2, I wanted to move to a RPi0, because of the smaller footprint.At first, the Unicorn Hat didn't want to work as usual. Only one LED was green, nothing else did show up.
After fiddling around and doing some g**gle, I was able to solve the issue:
Following the instructions from adafruit https://learn.adafruit.com/adding-basic-audio-ouput-to-raspberry-pi-zero/pi-zero-pwm-audio I changed the mode of pin 12 (BCM18) from previous input mode to ALT5.
The question is: wouldn't it be nice if your Unicorn library could check for the right mode of this pin?
Writing a warning to the console helps to determine the cause of the issue very easily.
Just my 2 cents.Cheers
/H.
