In the previous article, we used FreeRTOS to light up an LED, which essentially got FreeRTOS running. To effectively use an RTOS, it is necessary to understand how the scheduler works from a black-box perspective. Of course, if you want to study its internal implementation, you can read the source code. However, I feel that … Read more
The systems we usually share, such as µC/OS, FreeRTOS, RT-Thread, ThreadX, are all real-time operating systems (RTOS). So some readers ask: What is a time-sharing operating system, and does Linux belong to real-time operating systems? Real-Time Operating System (RTOS) RTOS, the full English name is Real Time Operating System, which means real-time operating system. 1. … Read more

Word Count: 2250 Content Index: ⭐⭐⭐⭐⭐ Every new application design requires either a microcontroller or a microprocessor. When choosing between the two, several factors need to be considered. Below is an overview and comparison of microprocessors and microcontrollers. When considering whether to choose a microprocessor (MPU) or a microcontroller (MCU), the type of application is … Read more
Abstract：We encounter many operating systems, such as Windows, Android, iOS, and Linux, which are all types of operating systems. Microcontrollers also have their own operating systems, known as real-time operating systems. So what are the differences between these real-time operating systems and the systems we use? The operating systems we commonly use are actually non-real-time … Read more

They are almost everywhere, from the smartphones and smartwatches we use daily to complex medical devices and industrial control systems, the application scope of embedded systems is becoming broader. Definition of Embedded … 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
