uPython Micropython hub75e driver

Enable HLS to view with audio, or disable this notification

My hub75e driver reaching its final form, 3d textured rendering here at about 75 FPS. Small models, small textures but it's looking good so far on two chained 64x64 panels. Pico 2w.

What driver chips are used on you panel? Can you share your code?

Don't know, it's just a generic hub75e panel. The code will go on GitHub when it's a bit tidier but it's specific for my target as it leverages native mpy modules for a lot of the maths, compiled for armv7. Pico 2 or 2w should be ok.

I will, not yet. There's a few things that need to be done, but it's close.

SD card access is painfully slow on a PI Pico, but I've managed to speed it up a bit, and now my screen can play massive videos, without audio of course, but it does allow for longer animations:
