Comprehensive Analysis of FreeRTOS Task Management: Mastering Core Techniques from Creation to Deletion

by

1. Basic Concepts In the context of the entire microcontroller program, we refer to it as an application. When using FreeRTOS, we can create multiple tasks within the application; some documents refer to tasks as threads. For example, in daily life, a mother may need to do two things at the same time: Feeding: This … Read more

Understanding FreeRTOS Cooperative and Preemptive Scheduling Algorithms

In FreeRTOS, Cooperative Scheduling and Preemptive Scheduling are two different task scheduling algorithms. The core difference between them lies in the triggering mechanism for task switching and how task priorities are handled. 1. Cooperative Scheduling 1.1 Concept Cooperative Scheduling is a non-preemptive scheduling algorithm. In cooperative scheduling mode, task switching only occurs when a task … Read more
