Printing strings on a Virtual COM port with an STM32 and ChibiOS

This article contains some simple examples to understand how to print escaped strings when you are approaching STM32 and ChibiOS. Escaped strings are very useful while developing because you can use them to print data while the application is running. Strings are widely used for debugging purposes when a debugger is not available but this is not the case.

Every STM32 development kit is equipped with a STLink debugger. Starting from STLink V2-1, the debugger offers a virtual COM port and, in this article, we are going to use this feature to print data avoiding to put continue reading...

Dealing with push-buttons using an STM32

This article contains some simple examples to understand how to deal with push-buttons when you are approaching STM32 and ChibiOS. The button can be considered the simplest input peripheral that can be connected to a microcontroller. Because of that, usually, every embedded development board is equipped with a button marked as “User Button” and this means it is actually connected to a GPIO pin you can read via software.

To understand this article with proficiency, you should match few requirements:

You should have an STM32 development kit and be able to do basic stuff continue reading...

Dealing with LEDs using an STM32

This article includes some simple examples to understand how to deal with LEDs when you are approaching STM32 and ChibiOS. The LED can be considered the simplest peripheral output you can connect to a microcontroller. Because of that, usually, every embedded development board is equipped with a LED marked as “User LED” and this means that it is actually connected to a GPIO pin you can drive via software.
