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
Follow+Star Public Account, don’t miss out on exciting content Source | Micron Technology Have you found it impossible to reduce task scheduling or delay precision below milliseconds when using a Real-Time Operating System (RTOS)? You might have had to write a lot of application code outside of the RTOS. While this approach works, it raises … Read more
Author | strongerHuang WeChat Official Account | Embedded Column When developing projects based on RTOS, it is common to encounter mutual exclusion situations, for example: multiple tasks need to use a single UART serial port for data transmission. If mutex locks are not added, a higher priority task may preempt the serial port and send … Read more

This is a very broad question. Currently, there are hundreds of RTOS available in the market. If you talk about the minimum requirements for MCU, I … Read more
Scan to FollowLearn Embedded Together, learn and grow together There is a very popular question on Zhihu — “What are the advanced uses of MCUs?“ It is said that MCUs themselves are not particularly advanced, but during the MCU development process, certain standardizations must be followed, such as defining variables and functions, determining their lifecycle, … Read more
In embedded system development, real-time operating systems (RTOS) play a crucial role, especially in applications that require high responsiveness and time determinism. MiROS (Minimal Real-Time Operating System) is a minimalist real-time operating system kernel designed specifically for ARM Cortex-M series microcontrollers, aimed at helping developers understand the basic concepts of RTOS. Overview of MiROS MiROS … Read more
