Task Priorities in FreeRTOS – Part 3: The Importance of Low-Priority Tasks
In our previous articles (part 1, part 2), we established a foundation for task prioritization in FreeRTOS, outlining a multi-tier system for effective task management. To further refine our task hierarchy and optimize system performance, we will now introduce a new priority level for tasks that are critical but do not require immediate execution. The […]
C++ on Microcontrollers: A Fragmented Perspective
The integration of C++ into the realm of embedded systems, particularly microcontrollers, has been a significant development. This powerful language, with its object-oriented paradigm and rich standard library, offers a compelling proposition for developers. However, when it comes to the constraints of microcontrollers the allure of C++ starts to fade. The MMU: A Missing Piece […]
Task Priorities in FreeRTOS – Part 2: Beyond the Basics
In our previous article, we established a foundation for task prioritization in FreeRTOS, suggesting a three-tier system for most applications. However, certain applications may require an additional layer of complexity. In this article, we’ll introduce a dedicated priority level for a specific yet common type of tasks: device drivers. Understanding the Device Driver Challenge While […]
