Recently, I used FreeRTOS in a project and became curious about idle tasks and hook functions, so I wanted to understand what these two are used for. Here, I will share some of my insights.1. Idle TaskThe idle task is a task that is created by default after the FreeRTOS system starts, and it has … Read more
Follow+Star Public Account Number to not miss exciting content Author | Source: gitee Friends who have worked on projects should know that in projects, using methods like disabling global interrupts to protect critical sections can lead to harmful consequences (loss of responsiveness, processing delays). For example, high-speed communication can result in frame loss, and high-speed … Read more
This article is approximately 7097 words and takes 8 minutes to read A Real-Time Operating System (RTOS) is an operating system that manages hardware resources in real-time, supports applications, and processes data. It defines the timing for real-time task processing, interrupt latency, and the reliability of hardware and applications, which is particularly important for low-power, … Read more
