Explore the process of customizing a standard TouchGFX template for the STM32H7B3I Discovery Kit in this 26-minute video presentation. Learn to configure the template to utilize external SDRAM as a frame buffer, covering topics such as SDRAM timing configuration, X-Cube-TouchGFX setup for double-buffering, and SDRAM initialization sequence. Follow along with live demonstrations on using STM32CubeMx, STM32CubeIDE, and TouchGFX Designer to set up SDRAM, add dynamic widgets like an analog clock, and implement the necessary code for functionality. Gain practical insights into building and loading the code, culminating in a running demonstration of the customized application.
