Raspberry PI 5 and the 1.54" SPI Colour Square LCD (240x240) Breakout

Has anybody got this to work? I can make the screen flash on and off again, but that’s about it, when I try and load an image it’s just black.

I’ve had to copy the ST5579 library code into my own python file and I’ve attempted to recode it using gpiod (I understand the PI5 won’t work with the GPIO library the ST5579 library was written with), so maybe that’s my issue?
