STM32 Tutorial 00x - Title

Embedded Software Programming on the STM32 Plattform

---

You can use the STM32CubeMX software to create the necessary configuration files to enable the UART port(s) with the required parameters. In this tutorial I’m going to explain how you can use the UART interface to print values using printf() and react to user input via UART interrupts.

Requirements

You need any of the STM32-Nucleo 64 boards. I am going to use the STM32f103rb board in this tutorial. You should also have an the STM32CubeMX Configurator and a compatible IDE installed. Check Tutorial 000 for installation instructions. I will build upon the Tutorial 001 - GPIO Operations. It is also handy if you happen to have the User Manual of the Nucleo-64 board and the datasheet for the STM32 microcontroller nearby.

• STM32 NUCLEO-F103RB
• STM32F103c8 Datasheet
• STM32 Nucleo-64 boards User Manual UM1724 (pdf)
• Description of STM32F1 HAL and low-layer drivers UM1850 (pdf)
• STM32CubeMX installed
• arm Keil µVision 5 IDE installed
• (read through Tutorial 001 - GPIO Operations)

---

This tutorial comes with the following source code files

• STM32F103-Tutorial-001-GPIO.ioc (STM32CubeMX project file)
• main.c
• stm32f1xx_it.c

STM32CubeMX Settings

For this tutorial I am using the same file as in the previous tutorial.

If you check the default settings of the USART2 communication interface, you will see the following settings:
