What is the best tutorial or learning resource to get started learning how to program Graphics (widgets) on the Touchscreen of the STM32F746 Discovery board? I currently use STM32CubeMx and Keil MDK for the STM32F4 Discovery board.

Hi,

To rapidly start implementing a GUI using widgets, the best starting point on ST devkit such as the STM32F746 Discovery board is to install TouchGFX Designer (from X-CUBE-TOUCHGFX - TouchGFX advanced and free of charge graphical framework optimized for STM32 microcontrollers - STMicroelectronics).

Then create a project using the dedicated Board Setup:

From there you can directly start implementing a GUI and program the board directly from the Designer.

All further information can be then retrieved from the TouchGFX Documentation:

Installation: Installation | TouchGFX Documentation

General user guide: Designer User Guide | TouchGFX Documentation

Custom widgets: Custom Widgets | TouchGFX Documentation

By default the underlying IDE is STM32CubeIDE, to change it to IAR of Keil you need to install STM32CubeMX tool (STM32CubeMX - STM32Cube initialization code generator - STMicroelectronics) and change the IDE in the provided project (.ioc file):
