I’ve just bought this screen:
And trying to run official SPI code example with Arduino UNO r3, here are the sources:
I have managed to show something on the screen using the GxEPD library but it very limits my memory.
An official example is very lightweight but for some reasons doesn’t work. The display is not responding at all…
What could be a reason?
I checked all ports connection 100 times. And it works with GxEPD as I mentioned…
