Hi everybody, I have a custom board with STM32F777 + 800x480 TFT LCD (NHD-5.0-800480TF). The interface is RGB24 bit. LTDC color format is RGB565. Pixel clock is 25MHz.
I found that some color seem to be displayed incorrectly. In the screen below, there are artifacts in the buttons, the same pattern repeats on all buttons. Have any one got the same issue before? Any idea if this hardware design issue, or timming or LTDC misconfigured?
Thanks
