Hi there,
So which display driver are you using? TFT_Espi or ? You need to use the seeed version and edit the config for it. Go load up one of the Drag & Drop Uf2 files for to test it.
There’s a zip file attached to the first post that has the chimp wink gif demo. Take a look at that thread to glean some good info.
