# STM32F746-Minimal-Blocking-Uart-Driver

Minimalist blocking UART driver for STM32F746-Disco UART1 ST-Link COM Port

Clock: default, no changes (must be 16MHz HSI).


Only activate GPIO, set them to Alternate Function USART1, Very High Speed.


USART1 is the USART connected to ST-Link that makes virtual COM port on PC.



This project is a proof of concept (not of UART, but of me - that I can).


It's not as modular as it could be, but it's not intended to be perfect. Might be useful for someone who wants to figure out how the stuff works.


I commented everything to make it simple to understand.



Hardware:


STM32F746 Disco board, Windows PC 



Software:


STM32CubeIDE v1.7.0, Putty for UART communication;


No libraries used except for CMSIS register definitions.
