Thank you for helping.

STM32CubeIDE Ver1.3.0
STM32CubeMX Ver5.5.0
TouchGFX Ver4.12.3
Board: STM32F769I-DISCO
This board is connected to LCD by DSI interface.
How do I change the source code to make the interface RGB parallel when creating a custom board?
If I remove MX_DSIHOST_DSI_Init () and set GPIO to output in RGB parallel, do I need any other changes?
Thank you.

Generally, you can check the STM32F746G-DISCO or other ATs that have an LTDC. Can we start there? I think you'll see what to do (LTDC interrupt handler signals OSWrapper::signalVSync to unblock TouchGFX Engine), so it's a lot simpler.

Dear Martin,
Thank you for helping.
It is assumed that the device uses F769.
What should I think?

Did you take a look at the code in the application templates e.g. F746G-DISCO? Generally, if you remove the DSI HOST configuration in CubeMX and tell TouchGFX Generator to do Parallel RGB (LTDC) then you will have the appropriate driver. Should be all you need.
