Uncover the versatility of General Purpose Input/Output interfaces with detailed discussions on their configuration, use cases, and essential role in hardware-software interaction.
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 ...
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 ...
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 ...
