ST7565 Graphic LCD - wrong colors

Post by wordclock110 »

Hello everyone,

I have a problem getting my ST7565 Graphic LCD to work right.
It is actually a JeeLab - Graphics Board. I am trying to get it to work with the adafruit/ST7565-LCD library.
It almost works. I managed to adjust the Pins for the display and the backlight LED. The only problem, I can't figure out it why the pixels aren't quite right.
It is hard for me to explain. There seems to black screen on top of the actual content. I added a picture so that you can see what I mean.
Does anyone know which setting I need to adjust?

Thanks for your help
David

It looks like the contrast is set too high. I don't know how you'd adjust that on a JeeLab board, but try lowering the contrast if possible.
