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
Article Length: 8000 words, Content Quality: ⭐⭐⭐⭐⭐ 01 Clarifying the Differences First, “Embedded” is a concept without a precise definition; various books have their own interpretations. However, the main idea is the same: compared to general systems like PC, embedded systems are specialized systems with a streamlined structure, retaining only the necessary components in both … 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
