Hello,
Hopefully someone can provide me with some info on a problem I am having...
I am changing the display of the STM32F429 Discovery board (240x320) to a NewHaven display (480x272):
NHD‐4.3‐480272EF‐ATXL#‐T
The new display lists the driver as the Himax HX8257‐A, which is connected straight by RGB and sync signals (using internal controller of STM32F429 only). The issue I have is that the full area of the display is not used, the display works, I can run the emWin demos but they don't quite fit the screen properly. As far as I can tell the hardware is being initialised correctly, I can get a test pattern filling the whole LCD when I initialise the on board controller... the problem is when I use emWin the windows is not the size it should be.
I have attached a photo so you can see, does anyone have any ideas what this is most likely to be?
Best Regards,
Ant
