This project is based on Contextual Eelectornics course that brings up a the USART peripheral on STM32 micro.
In this specific example the board I have is a Nucleo F446ZE and this particular project implements a dead simple "serial interface".
The board is setup to run at a 115200 buadrate and is essentially an echo server with the following characters additionally toggling leds
- 1 -> Toggles Green Led on board
- 2 -> Toggles Blue Led on board
- 3 -> Toggles Red Led on board
On boot the board will will setup the Initialize all the device and then print a header out to the USART 3 device that includes the firmware and hardware version along with the date compiled.
It's basic but a start.
