I have a 3x (64 x 64) HUB75 panel running with a Teensy 4.1 and Smartmatrix Shield up and running. Serial connection and SD card working. I am now seeking an example code to read an image (jpg or png) from SD card and display it on the background layer. In a worst case, I could go for GIF, but that is only plan B. Any help is greatly appreciated.
