Hi,
Is it possible to reset a part of this screen?TFT Shield specs
I have made it work but the time and date become after a while white bloks.
This is because the screen does not refresh and the pixels get white voor number 1 and then the pixels for number 3 get also white .. and so on. Is there a solution for this?
This is my code:
