1 year ago my mistake, fixed by following the instructions and setting OPI PSRAM .
I received my board, but the silkscreen states it is version 2.0.
I appear to get the following error when using gfx library with the following settings : -
(using gfx version 1.3.1)
`
include
define GFX_BL 2
define TFT_BL GFX_BL
