Скачать или смотреть Bare Metal STM32 #3: Implement a simple UART transmit receive driver + retarget printf & scanf

This video shows you how to implement a UART transmit-receiver driver in Bare-metal STM32 to make a simple echo program. You send data through the serial monitor to STM32, and then it echoes back to your console. The guide also shows how to retarget printf and scanf.
