I have a 7 Pin ST7789 driven TFT Display that I am having issues with. However, I am not sure if it is the display or the state of the microcontroller (in my case an Arduino Nano).
My issue is that, once I have uploaded the code, the screen flickers then remains blank. If I upload a new sketch, or reset the microcontroller the screen comes on and displays until the microcontroller has booted, then goes blank again.
Any advice / suggestions will be gratefully received.
