This article introduces the tasks and scheduling kernel implementation of FreeRTOS.1. Concept of Tasks In FreeRTOS, a task is the smallest unit of system scheduling and execution. Each task has its own stack space, program counter (PC), registers, and state. Task Stack Spaceis a contiguous memory area that stores local variables, function call information, and … Read more

Importance of Program Architecture Many people, especially beginners, often write code without an overall plan, leading to increasingly messy code and constant bugs.Ultimately, the … Read more
Tasks are the smallest units of execution competing for system resources. Multiple tasks with the same priority can share the same priority level. In FreeRTOS, if configUSE_TIME_SLICING is defined as 1, then multiple ready tasks with the same priority will share the processor in a time-slicing manner, where one time slice equals one tick. Task … Read more
