Enable LTDC in CUBEMX

Hi,

We are in the designing phase of a STM32H7 board which will control a RGB24 display. To check which package would suit are needs the best we would like to see the RGB pinout on different MCU's. But for some reason I don't find the LTDC interface at the multimedia tab of these H7 controllers. 

If I open the boardfile of the H7 discovery board with display I do see the LTDC interface at the multimedia tab.

When we start a plain stm32H7S3L8HxH cubemx project. How to enable the LTDC interface?

Best regards

Hello,

Simply because STM32H7S3 doesn't have LCD-TFT interface which is not the case of STM32H7S7 (the one used on the DK board): 

From the datasheet:
