Uncanny Eyes
This is a project for having 1 or 2 animated eyes displayed on round LCD screens.
I ended up using the uncannyEyes_GC9101A from the Examples in the last link below.
Had to comment out the #define USE_ASYNC_UPDATES line. In the config.h, all of the pins can be shared except for the CS pin.
