Minimal I2C/UART DMA demo for STM32F746-DISCO
UART1 ST-Link COM Port
Clock: 216MHz. USART1 is the USART connected to ST-Link that makes virtual COM port on PC. I2C3 is connected to FT5336 capacitive touch panel. TIM6 and TIM7 provide regular touch panel scanning.
This project is a proof of concept (that I can).
Might be useful for someone who wants to figure out how the stuff works. I commented almost every line to make it simple to understand.
Hardware: STM32F746 Disco board, Windows PC
Software: STM32CubeIDE, Putty for UART communication; No libraries used except for CMSIS register definitions.
