Hi all! I have Recently bought a ESP32-ST7796 for a NmMiner.
However, I'm struggling quite a bit. I cant seem to get the LCD to work...
I know it works initially as it came out the box and lit up...

The link I bought from

I have flashed the device, tried all supported devices & the only one I get somewhere with is the "ESP32-2432s028r-st7789".
It is coming up with the mining codes so I know it is 100% mining.
But the display is not showing up? - Display is 320x480

I did have a 2.4 screen ESP32-2432s028r-ILI934" and that worked a treat.

I am completely new to codes so I apologise if it is not brilliant to understand.
