Hello @Sascha_St ,
Have you looked at the Application Template for STM32H743-EVAL available in TouchGFX Designer ? It can be a starting point for your project.
Otherwise, you will find the STemWin working example available with STM32CubeH7 MCU package:
STM32Cube_FW_H7_V1.8.0\Projects\STM32H743I-EVAL\Applications\STemWin\, it contains a set of source files that implement a simple "Hello World" application based on STemWin for STM32H743xx Devices.
Have a look on these application notes for more details about LCD configuration and how to use STemWin Library step by step:
- AN4323 "Getting started with STemWin Library"
- AN4861: LCD-TFT display controller (LTDC) on STM32 MCUs
