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. Overview of FreeRTOS FreeRTOS is a lightweight, open-source real-time operating system suitable for embedded systems. It provides features such as task scheduling, synchronization, and communication, characterized by its portability, configurability, and efficiency, making it widely used in resource-constrained embedded devices. 2. FreeRTOS File Structure (1) Source Folder This contains the core source code of … Read more
1. Introduction FreeRTOS has become the preferred choice for embedded real-time systems due to its small footprint, portability, and flexible customization capabilities. Before delving into the source code, let us review the core requirements of real-time operating systems (RTOS) in the embedded field: Determinism: Predictable task response delays. Scalability: Support for memory usage ranging from … Read more

By configuring <span>Cron</span> appropriately, users can easily schedule tasks to run every 5, 10, 15, or 30 minutes. This article will delve into how to use <span>Cron</span> to implement scheduled tasks at these intervals, covering everything from basic concepts to advanced configurations, aiming … Read more
Understanding the Basic RTOS Features of VxWorks: A Practical Guide for Engineers VxWorks is a real-time operating system (RTOS) developed by Wind River, widely adopted in mission-critical embedded systems. This article will introduce the fundamental features of VxWorks, including task control, inter-process communication (IPC), signal handling, and virtual devices, along with practical code examples. Why … 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
Click the above blue text to follow us Real-time systems are crucial in embedded applications, with the core focus on ensuring tasks are completed within specified time frames. Based on the strictness of deadline adherence, real-time systems are classified into hard real-time and soft real-time. Hard real-time systems require tasks to meet deadlines 100% of … Read more
