Minimal DMA-based UART driver for STM32F746
Minimalist DMA-based UART driver demo for STM32F746-Disco UART1 ST-Link COM Port
Clock: default, no changes (16MHz HSI). USART1 is the USART connected to ST-Link that makes virtual COM port on PC.
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.
