Digital outputs are an essential part of embedded systems development, and one of the best ways to experiment with them is by using LEDs. In this article, we will take a hands-on approach to digital output using LEDs hooked together with resistors as a peripheral. Along the way, we will explain ...
When it comes to lighting, LEDs have become increasingly popular in recent years due to their numerous advantages over traditional light sources such as incandescent bulbs and fluorescent tubes. One of the most significant advantages of LEDs is their energy efficiency. Unlike incandescent ...
Breadboards are an essential tool for anyone interested in electronics. They allow you to quickly connect through-hole components together and experiment with electronics. In this article, we will explore the different types of breadboards, including solderless breadboards and ...
Digital inputs are one of the primary ways embedded systems interface with the external world, allowing device-to-device communication and MCUs to respond to user inputs or environmental changes. In our previous article, we covered the fundamentals of the PAL driver of ChibiOS/HAL, which ...
Embedded system applications are becoming increasingly complex, and as a result, developers are constantly looking for new ways to make their firmware nimbler, simpler and more efficient. One of the most critical aspects of programming embedded systems is the use of interrupts to handle ...
The General Purpose Input/Output (GPIO) is a crucial peripheral in microcontrollers, enabling communication with the external world by sending and receiving signals through its input/output lines. GPIOs are highly configurable and versatile, with a single microcontroller often capable of ...
In this article, we will demonstrate how to create multiple threads using parametric functions. This means that while the function executed by each thread is the same, the specific behavior is influenced by passing different parameters each time.
To illustrate how parametric threads work, we ...
The board files are a critical component of a ChibiOS-based project. They define how peripherals are connected to the microcontroller and provide information related to key elements that depend on the board in use. This article will discuss what board files are in ChibiOS, their role in a ...
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 ...
