multiple MAX7219 matrix

by MikeB35 on Thu Nov 19, 2020 12:08 pm

Hello,
Has anyone ever tried to scroll a message on an assembly of several MAX7219-based LED arrays (16x8 or 32x8)?
The methods available in the 8x8 library are low-level methods such as lighting a pixel.
An example would be really welcome!

Thanks for your reply.

@MikeB35,

Good question. I don't know of one of our own libraries that do this, but there are some on github. This one has an example with four chained LEDs.

Thanks but the link is for Arduino not for CircuitPython.
Really, I can't find an equivalent.
Maybe I'll try to be part of a micropython library and modify it... To see if I'll succeed.
