Hello everyone, I can't clerarly understand if it's possible to connect my display(HIMAX7019) too STM32F429 via LTDC. According to display datasheet I have to use all RGB0:RGB7 pins, but I cubeMX I have only RGB2:RGB7 pins. According to datasheet I found out that display is working on RGB 8bit parallel interface, but LTDC supports only 18 and 16 bit interfaces. So, is it possible to run the display? Where can I find lost RGB0:RGB1 pins?

Sometimes each color 0 -> 6 and 1 -> 7 are connected instead to insure full display intensity, but above is more clean IMO.
