In this article we’ll see what it takes to get started with basic UART communication on STM32 microcontrollers. ... For USART1 on an STM32F042 MCU, for example, we look in its datasheet ...

The STM32 line of microcontrollers – usually seen in the form of an ST Discovery dev board – are amazingly powerful and very popular micros seen in projects with some very hefty process… ...
