Resolve pin multiplexing for LTDC, USB and FMC

[SS.Sagar]

I am trying to resolve this pin mapping for the STM32f767 processor,

FMC_D9 is connected to SDRAM so PE12.

I am planning to use USB OTG so PA10 will be connected to PA10.

So, with the above connection, only the pin is left that is PG12.

How to resolve the connection for following features, LTDC_B4, FMC_D9, LTDC_B1, USB_OTG_FS_ID.

PIN PE12 - LTDC_B4/FMC_D9

PIN PA10 - LTDC_B4/LTDC_B1/USB_OTG_FS_ID

PIN PG12 - LTDC_B4/LTDC_B1

LCD_B4 on PI4 or package with more pins. Second choice is F769 and DSI display.

Some displays dont need B1 RGB666

Thanks for the reply. I want to use LTDC as a TFT interface. I think more package MCU will be a good choice. Is there any other MCU which has same package and i can use.

LTDC is parallel to RGB, but same way is

LTDC ... DSI ... serial display.

Check your display connector is realy 24bit RGB ? When only 18bit you dont need LCD_B1 then no problem...
