01 Fundamentals of Real-Time Operating Systems (RTOS) Real-Time Operating System (RTOS) is an operating system (OS) designed to provide real-time application processes with data, typically without buffering delays. The key factors in an RTOS are minimal interrupt latency and minimal thread switching latency. The value of an RTOS lies in its response speed or predictability, … Read more

Microsecond-Level Delay Design Solutions Generally, in an RTOS system with a clock of 1KHz, the minimum time for thread_sleep() is 1ms. In real-time control, there are situations where microsecond (us) level delays are required. What should we do in this case? There are two implementation approaches for microsecond-level delays: one is to increase the system … Read more
Reader *Shi San* asks: Can the blogger introduce methods for multiple tasks to access the same hardware under RTOS? For example, multiple tasks need to use the serial port to print information. My answer is: Both mutexes and queues can solve the access conflict problem. Multithreaded access to the same serial hardware is commonly used … Read more
We are all familiar with processes and threads, but their terminology might differ in RTOS systems. The term we are familiar with is Task (Task), which is similar to Thread (Thread). You will find that in some places, RTOS tasks are also referred to as threads. However, in RTOS, there is another less common program … Read more
