STM32H7 LTDC (LCD MIPI DBI)

I am using STM32H723ZG with LCD controller ILI9488 working with MIPI DBI type B interface (16 data lines).

Interface pins on the LCD controller are:

  • CS(Chip Select), DC(Data/Command), RD(Read signal), WR (Write signal).

ST LTDC peripheral does not have DC, RD.

  1. Can LTDC CLK be configured to act as WR?
  2. How can I control the number of bytes being sent via LTDC (how to control the number of clocks in the CLK signal)?
  3. Can I send Commands to the LCD controller (ILI9488) using ST LTDC? If yes, how can I sync between the DC (GPIO) and WR (LTDC?)?
