Hi,

I am creating a project with TouchGFX graphics on STM32F412G-DISCO. I have already downloaded and installed XCUBE-TOUCHGFX 4.14 and it is visible in "additional software" category. When selecting driver, the LTDC is grayed out. (attached) It is also absent in the "multimedia" category. How to enable LTDC. Please suggest on this.

Thanks,

Eshwar

ENV:

CUBEMX 6.0.0

Hi,

Are you just using the F412 disco or are you modifying it? I will investigate but meanwhile you can also create a project directly from TouchGFX Designer for the F412G-disco board. The CubeMX settings are done for you. You can use them as inspiration if you wish to start from scratch. If i remember correctly the F412 disco uses the FSMC interface instead of LTDC which would explain the LTDC being absent.

Hi,

Thanks for your reply. I can see FSMC in "connectivity" category. I hope this gets the LCD working if not for LTDC interface
