With our ESP32-S3 TFT experimenter board, we're now able to use the Arduino_GFX https://github.com/moononournation/Arduino_GFX library by moononournation which has native RGB TFT support and excellent example code. This example is playing MJPEG files, a simple animation format https://en.wikipedia.org/wiki/Motion_JPEG with just JPEGs glued together. We wired up a MicroSD card over SPI for quick file storage and retrieval, or 1-bit MMC works, too. files are converted with ffmpeg: 'ffmpeg -i "wash.mp4" -vf "fps=10,vflip,hflip,scale=-1:480:flags=lanczos,crop=480:480" -pix_fmt yuvj420p -q:v 9 wash.mjpeg', natch! And then they play, about 9fps is the rate we're getting for 480x480 pixels.

Coming soon - this is a quick sketch we did of an RGB TTL driver PCB to help us try out all our funky-shaped displays. We reused most of the Matrix Portal S3 PCB, but instead of the RGB matrix connector, we popped on a 40-pin FPC. 16 GPIO go to the RGB pins, then there are 4 control pins for HSYNC, VSYNC, DE, and PIXCLK. Three more pins for touch screen I2C and IRQ. Then a NeoPixel, two buttons, and 3 SPI pins for configuring the screen controller, and we're almost out of pins! An I2C GPIO expander could save us a couple pins at the expense of more complex drivers, but for now, we will make it easy to get the displays running, and we can play silly pin games later.
