Can't set 8 bit diplay type on LTDC Controller for STM32H723ZGTX

[LPZ]

Good morning,

for a project I have to set the LTDC display type to be 8 bit for some bottleneck, but doing that on STMCubeMX for my MCU STM32H723ZGTX there are only 24, 18 and 16 bit configs available.
How can I set this value to be 8 bit?
Thanks for the patience

what kind of display you are talking about ?  there are a few of them to use 8 bit data.

@MNapi here, he's talking about a display through LTDC interface and not via FMC.

@LPZ I'm not an expert of that peripheral but from the AN4861 table 4:

if he is talking LTDC then we would have something like RGB323 format.

You would use pins R7, R6, R5, G7, G6, B7, B6, B5. Nobody is using something like this.

There is no such a thing.

RGB565 is the most popular.

a have a few projects connected to 8 bit TFT and you use FMC not LTDC
