A very basic example using the 'Animated GIF' library by Larry Bank + the SD / File system library provided for Arduino by Espressif.
Some default HUB75 pins need to be remapped to accomodate for the SD Card.
- Format a SD Card with FAT32 file system (default setting)
- Create a directory called 'gifs'
- Drop your gifs in there. The resolution of the GIFS must match that of the display.
