The author of this article, Jacob Beningo, is an embedded software consultant with over 15 years of experience in microcontroller development based on real-time embedded systems. Below are some suggestions he offers on selecting an RTOS, which we hope will inspire you. Real-Time Operating Systems (RTOS) are now part of over 50% of embedded projects, … Read more
Follow+Star public number, don’t miss wonderful content Author | strongerHuang WeChat public account | strongerHuang Everyone knows that RTOS (Real Time Operating System) is a real-time operating system. So what exactly is a real-time operating system? Is RTOS really real-time? I believe many beginners have such doubts. What is RTOS RTOS:Real Time Operating System, which … Read more
Recently, some friends have been asking: when learning RTOS, should one choose µCOS or FreeRTOS? In fact, similar questions are often asked by many, and there is no unified answer. Generally speaking, once you learn one RTOS, it becomes relatively easy to learn others. Currently, both µCOS and FreeRTOS are suitable for beginners. µCOS has … Read more
When learning the principles of operating systems, you will come across terms like “time slice”, “preemptive”, and “real-time”, which many people may not fully understand, even after studying or working in operating system development. Ultimately, it comes down to not grasping some basic principles of operating systems. This article aims to address similar questions that … Read more
As a pioneer and innovator in RTOS, the author shares a very clear viewpoint: Many engineers feel that all RTOS options are similar when choosing an RTOS, and believe that some lightweight kernel abstractions can meet the major demands for safe and reliable systems today. This thought is fundamentally flawed. No company or project team … Read more

First, Concurrency The efficiency of concurrent programming is low when writing bare-metal software, as there is inevitably a large while(1) loop in the main program that contains almost all business logic of the project. Each business logic section has delay loops, which causes all logic to work in a serial manner. This results in CPU … Read more
(1) Introducing RTOS? Many friends and colleagues have asked me how to choose an RTOS in practice. This question is really difficult to answer; it is very complex. In practice, there are at least three situations: 1. In some places, there is simply no need for an RTOS; perhaps the system designer is a fan … Read more
NO.1 Pi Hole Note: This Pi Hole deployment on OpenWrt was successful, but it failed to work. DNS filtering only works within OpenWrt, and there is no data reflected on other clients. Therefore, after this deployment, the R5C will prioritize resolving the wireless card issue, and other plugins and Docker applications will be postponed. I … Read more
