How to start a touch in STM32F746G Discovery?

I chose “Inicjalize all perypherals with their default Mode”.

I added GRAPHICS (STemWin).

I made a window with a button.

I inserted correctly into the plate.

Displays correctly.

What do I need to do next?

Hi,

If you are using the STM32Cube FW_F7 package from ST, you might want to refer to the emWin example project found under:
STM32Cube_FW_F7_V1.8.0\Projects\STM32746G-Discovery\Demonstration\STemWin\

In the subfolder of this directory (\Core\Src) you will find a file named k_bsp.c. In this file the touch input from the LCD gets passed to emWin using the function GUI_TOUCH_StoreStateEx().
Use this files as reference or if possible use it as is.

Beside of that you can also download our example project for this device from our webiste:

segger.com/evaluate-our-softwa…/st-stm32f746g-discovery/

Additional to the project you will need Segger Embedded Studio and the 'ST-Link to J-Link converter tool'.
