1 FreeRTOS Since RTOS requires a certain amount of system resources (especially RAM), only a few real-time operating systems such as μC/OS-II, embOS, salvo, and FreeRTOS can run on small RAM microcontrollers. Compared to commercial operating systems like μC/OS-II and embOS, FreeRTOS is a completely free operating system, featuring open source code, portability, scalability, and … Read more
When programming microcontrollers, we know there are two basic operations: bare metal and operating systems. Bare metal means a large loop running repeatedly. Today, we will discuss several commonly used operating systems. A Real-time Operating System (RTOS) runs tasks in order, manages system resources, and provides a consistent foundation for developing applications. Compared to general … Read more

This article is from CSDN Blog on FreeRTOS Basics, and it mainly shares important considerations for using FreeRTOS with Cortex-M. Original link: https://blog.csdn.net/zhzht19861011/article/details/50135449 Before reading this article, you must understand the meanings of two macros defined in FreeRTOSConfig.h. The article “FreeRTOS Kernel Configuration Description” explains these two macros: ●configKERNEL_INTERRUPT_PRIORITY ●configMAX_SYSCALL_INTERRUPT_PRIORITY FreeRTOS is a perfect match … Read more
Abstract: We encounter many operating systems in our daily lives, such as Windows, Android, iOS, and Linux. Microcontrollers also have their own operating systems known as Real-Time Operating Systems (RTOS). So, what are the differences between these real-time operating systems and the ones we commonly use? The operating systems we frequently use are actually non-real-time … Read more
This article is from the Jishu Community’s evaluation activity of the Allwinner XR806 development board. The author used the XR806 development board and the XR806 SDK based on FreeRTOS to implement custom sending of 802.11 Beacon frames, and conducted wireless packet capture analysis and scanning tests to verify the sending results of the frames. Environment … Read more
1. Design Concept For controlling the LED light, we can imagine the functions of the LED light. The first is the switch, brightness, and color, which are the main three functions. How can we abstract these three functions? Regardless of what the underlying LED device is, we can abstract it using this structure. As shown … Read more
1. What Sparks When C++ Meets Embedded Development? In our daily lives, electronic products come in various forms, from smartphones and smartwatches to electronic control systems in cars and automation equipment on industrial production lines. Embedded systems are truly ubiquitous. They act as the “hidden brain” of these devices, silently controlling everything, often with high … Read more
