In FreeRTOS, CPU utilization statistics are an important feature that helps you understand the performance of tasks and the system. This chapter will explain how to evaluate CPU utilization in FreeRTOS. Let’s learn together. First, let’s discuss what CPU utilization is. CPU utilization refers to the CPU resources occupied by the programs running on the … Read more
Task Management Single-task system for front and back ends Divide and conquer multi-task system FreeRTOS is a preemptive real-time multi-tasking system, where the core task scheduler allows multiple tasks to appear to execute “in parallel”, while in reality, only one task occupies the CPU at any given time. Tasks Task State • running • not … Read more
As AI enters the “usable stage,” how can we build a truly efficient, flexible, and controllable intelligent agent system? Relying solely on a “smart large model” is clearly not enough. For genuinely complex tasks, a clearly defined “team operation” is essential. The Multi-Agent-Manus (MCP process) has emerged, which is not just a simple execution chain … Read more

1. FreeRTOS Multitasking Architecture 1.1 Overview of Task Model As a lightweight real-time operating system, the core of FreeRTOS is its multitasking capability. In FreeRTOS, applications are organized as a set of independent tasks, each executing in its own context (such as a separate stack space) without dependencies on each other. Each task can be … Read more
Click the above blue text to follow us In embedded systems, RTOS meets strict timing requirements by managing multiple tasks. Task stack management is a critical aspect of RTOS development, especially when porting RTOS to new hardware platforms. Stack overflow is a common error in embedded development that can lead to memory corruption, unpredictable system … Read more
