Hello,
I am developing a GUI application with TouchGFX which I would like to run on a STM32F767ZI connected via LTDC to a display with RGB888 interface.
The display datasheet: https://newhavendisplay.com/content/specs/NHD-5.0-800480AF-ASXP.pdf
I am having problems with the configuration in CubeMX. I followed the guide in AN4861 to configure the LTDC but I am still having problems.
With my current configuration, when I set the background for the LTDC to red, and the Layer 1 to transparent (alpha = 0), I can see that the display correctly displays a red background.
When I set the Layer 1 to opaque (alpha = 255) with a red background, the display always shows a black background with a TV static like white rectangle on the top of the screen. It doesn't matter if I added TouchGFX as a Middleware or not, it always displays the same thing.
Current configuration attached.
Thanks in advance for the help!
