displayio and neopixel matrix

by laertes on Tue May 12, 2020 9:22 am

Hi,
i have a 8x32 neopixel matrix connected to a Gemma M0 that i would like to use.

Is there a lib like the arduino NeoMatrix or something in displayio that i can use for this?

It would be nice not having to create fonts etc manually.

/Lars

The Gemma M0 has the least memory of all CircuitPython boards and cannot fit `displayio` as a result. I'd recommend upgrading to an ItsyBitsy M4 or nRF52840 for much more memory.

I don't know if there are any Arduino options that will work.

Hi,
its for a wearable project so i think i will have to stick with the Gemma M0 for now as it has other advantages.

Arduino is a possibility but i was hoping to get to know circuitPython better so I will try to find a solution.
