SmartMatrix Library 4.0

With Teensy 4.x support coming to SmartMatrix Library, along with (still alpha quality) ESP32 support, and support for 1/4 scan panels and other panels with non-standard mapping, it’s time for a new major release. This is a good time to look at incorporating feature or bug fixes that have been sitting idle for a while, especially if there are any library changes that may require changing the API, or breaking existing code/examples.

I do plan on going through the open issues and pull requests in GitHub and including anything that I feel is important or low hanging fruit. What would you like to see included in the next major release?

(Please link to any existing issues/PRs on GitHub or consider creating a new one)

I’ve been using your “alpha quality” ESP32 support for over a year, works quite reliably for me :slight_smile:

I would definitely trade color depth for refresh rate, 16 bit, or even 12 bit (RGB444)

Not a must have, but just an idea.

I don’t have time to bring all the features I’d like into SmartMatrix Library 4.0, so it’s unlikely lower color depth will make it in. However, I just came across this fork where someone implemented a bunch of small color depth changes if you want to take a look:

If you do take a look, please let me know if it’s working for you.

Thanks Louis. Currently I’m using rPi for greater speeds/higher res, but if I need to improve my ESP32 speed, I’ll definitely look into that fork.
Also, I think it would be beneficial because it would use less memory and allow at least 128x128 at decent enough refresh rate.
