In the field of embedded systems and industrial control, the concept of a Real-Time Operating System (RTOS) is very important. They ensure that tasks are completed within a specific time frame, thus meeting strict timing requirements. This article will introduce the fundamentals of RTOS programming in C and provide code examples to help readers understand. … Read more
The following article is provided by CW32 ecosystem community user End: https://gitee.com/xcet/embedded-cw32-board-template/tree/master/ref/CW32-GCC-Clion-Template Recently, CLion has become free for non-commercial use, so I immediately downloaded the latest CLion 2025. Now, I will set up the CLion + GCC + CMake development environment for the domestic Wuhan Xinyuan Semiconductor’s CW32 microcontroller. CLion is a cross-platform integrated development … Read more
In embedded development, aside from development boards and oscilloscopes, the most frequent interaction is likely with terminal tools. Choosing the right terminal can double your debugging efficiency. Therefore, I have compiled a list of several high-frequency, practical, and straightforward terminal tools. While these tools may not cover every scenario, they are definitely robust enough for … Read more
