In this STM32 microcontroller tutorial, we explain how to properly setup a Universal Asynchronous Receiver-Transmitter device or briefly UART device. That is, we explain how to serially send data from an STM32 microcontroller to our computer. We explain how to write a C code that will establish a communication link that will send strings and numbers from the STM32 microcontroller to the computer and how to display the information on the computer screen. For example, in practical application, the material learned in this tutorial will enable you to print on the computer screen the sensor value processed by the microcontroller. That is, you will learn how to add to your microcontroller the functionality that is similar to Arduino’s serial monitor and println() function.

We use the program MobaXterm to read the messages sent by the microcontroller

This comment section is NOT a public forum where we provide free consulting and provide free answers to questions. We do not have the time and energy to do that. Please do not clog and overload our email and website traffic with technical questions that will not be answered here. There is a proper way of asking for consulting and help with ROS (see the contact information). However, we do not provide free help.
