yeah i did all that, but I first tried matrix_demo.py but that isn’t for my ws2812 “unicorn” 8x8 array. When I ran neopixel_demo.py it worked great, because i already had GPIO18 hooked up to my matrix 😃 IMG_20220109_145400

I’ve been having fun on this all day, I made a smiley face with draw.point function.

Thank you to the devs! My dad pays me in crypto when I do my chores, I’ll give you lunch money for helping me, just send me an address.
