1. Introduction During my work, I found that understanding these concepts only allows one to use RTOS at a basic level. To effectively utilize RTOS, one must understand some detailed mechanisms; otherwise, it is easy to fall into pitfalls and spend a lot of time troubleshooting. This article discusses related content in conjunction with the … Read more
When it comes to critical sections in FreeRTOS, there are several questions that need to be addressed:1. How is the protection of critical sections implemented?2. What is the relationship with interrupt priority?3. Will masking interrupts affect the operating system’s tick timing and cause a temporary loss of the system clock?With these questions in mind, let’s … Read more
1. Introduction to Queues A queue is a mechanism for data exchange between tasks, tasks and interrupts, and interrupts and tasks. Based on queues, FreeRTOS implements various functionalities such as queue sets and semaphores. All communication and synchronization mechanisms in FreeRTOS are based on queues. Queues have the following characteristics: 1.1. Data Storage Queues can … Read more
Twinko AI | Microsoft This article systematically organizes various AI agent orchestration patterns, providing a reference for architects and developers when building multi-agent (AI Agent) systems. As the capabilities of language models enhance, a single agent struggles to handle complex tasks, making multi-agent collaboration a trend. The article details five core patterns: Sequential Orchestration (linear … Read more
1.1 Task StatesApplications can contain multiple tasks, but generally, a microcontroller (MCU) in an application has only one core, meaning that at any given time, only one task is actually executed. This means a task can have one of two states, namelyRunning StateandNon-Running State. However, the non-running state can be further divided into several sub-states. … Read more

This article introduces the concept and usage of semaphores in the FreeRTOS operating system. It demonstrates resource sharing between different tasks through button presses and serial communication. Introduction A semaphore is a synchronization mechanism used for resource management when multiple tasks access the same resource. Semaphores can be categorized into binary semaphores (similar to “flags”, … Read more
