The Internet of Things (IoT) was still a very vague concept a decade ago. With the development of technology across various industries over the past ten years, and the deepening commercialization of 5G, the mainstream communication infrastructure representing the next decade, the initial slogan of “connecting everything” has gradually become clearer. The competition among IoT … Read more
This article mainly shares an open-source management module that helps achieve layered management of applications and hardware in an MCU project. Nowadays, project requirements are more complex, which naturally imposes stricter demands than before. From a technical perspective, I still recommend that everyone should maintain a layered structure (application and driver) in their projects. This … Read more
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
