Hi everyone, i'm working with the stm32f4 lcd module and i realized that whenenever i try to read the screen (actually the ram memory) some data are repeated. For example, after read and write the memory i dont have the same picture despite having done any kind of processing. This is solve just adding a delay function between each reading. I've tryed working with dma and I am having the same issue.
I would really preciated any help. Best regards
