stm32H7 LTDC confusion

[HOSI]

Hello, I want to use LTDC on the STM32H743VIT6 microcontroller, but when I enable this peripheral in CUBEMX, it does not activate correctly. For example, the pins for B are from B3-B7, while they should be from B0-B4, and the same goes for R, G.

Hello @HOSI 

I’m not an LTDC expert. But, think this is normal and no problem with this configuration according to the figure 32 of the AN4861, on a RGB666 display, the B  pins should be from B2 to B7 and not from B0 to B5 as on the display side. Same for G and R pins:

Best Regards.
