Houston,

we have a problem. Our Display shows us the Text mirrored. But we tried everything to get it right. Well it didn't worked. Can you help us? What do we have to change?

I guess you have to modify the initialization sequence for your display somewhere around here https://github.com/afiskon/stm32-ssd1351/blob/master/Lib/ssd1351/ssd1351.c#L127 Try changing the value from 0xA6 (NORMALDISPLAY) to 0xA7 (INVERTDISPLAY).

@Davi512 did you try the fix proposed above? Did it work for you?

Davi512 commented 1 year ago

I dont understand. Today is working without any issue

Well I don't have a problematic device on hands in order to do anything about this. If you'll figure this out please submit a patch.
