ChibiOS is a compact and fast real-time operating system supporting multiple architectures. It offers a multi-threading scheduler and related APIs to manage threads scheduling and priorities, events and inter-thread communication. It also provide an Hardware Abstraction Layer.
STM32 is a broad family of 32-bit microcontrollers based on ARM Cortex-M architecture. With hundreds of different chips, STM32 covers a broad range of applications. Thanks to cheap and valuable development kits it is quite easy to evaluate them or create an prototype.
No matter what they say, you will not be able to appreciate the performance of these MCUs without a good scheduler. Here we will provide resources to getting started with STM32 development board using ChibiOS/RT as kernel and ChibiOS/HAL as drivers. Pick one and read it! If you like it don’t forget to Share the knowledge.
In this example, we are going to see what is the simplest project you can create in ChibiOS. Following this demo, you will be able to continuously blink an LED with a simple single-thread application stripping down all the extra code. For this exercise, we are going to use the SDP-K1 and we are ...
A debugger is a powerful tool that gives us the chance to interact with the microcontroller at run-time. It allows to dynamically change the content of CPU registers, to read\write the RAM memory and to flash\erase the NVM memory of the microcontroller. The main purpose of a debugger is to ...
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 ...
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 ...
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 ...
The Inter-Integrated Circuit (often shored as I2C or I2C bus pronounced I-squared-C or alternatively I-two-C) is a widely used synchronous serial communication peripheral which communicates in half duplex mode using a multi-master-multi-slave architecture.
Like the SPI, the I2C is a Synchronous ...
The Serial Peripheral Interface (often shored as SPI bus) is a widely used synchronous serial communication peripheral which communicates in full duplex mode using a master-slave architecture with a single master.
As the SPI is a Synchronous Serial bus, a clock signal is generated by one of the ...
The Pulse Width Modulation (also known as PWM) is a digital modulation technique which uses duty-cycle of square waves to encode information. In communication field PWM surrendered to more advanced communication technique which uses more complex waveforms showing better noise rejection ratio ...
A microcontroller is a system which works on bits and bitstreams more than analog signals, anyway, those signals are still widely used in many fields especially in audio and power applications. An Analog to Digital Converter (or ADC) is a system that converts such kind of signals in a sequence ...
