The following content will use the standard library for the STM32F407ZGT6 model as an example.(1) Download the Source CodeYou can directly search for “FreeRTOS” in your browser to download it, or you can access … Read more
When programming microcontrollers, it is well known that there are two basic modes of operation: bare metal and operating systems. Bare metal refers to a large loop that executes repeatedly. Today, we will discuss several commonly used operating systems. A Real-time Operating System (RTOS) is designed to run tasks in a prioritized order, manage system … Read more

This article introduces the concept and usage of semaphores in the FreeRTOS operating system. It demonstrates resource sharing between different tasks through button presses and serial communication. Introduction A semaphore is a synchronization mechanism used for resource management when multiple tasks access the same resource. Semaphores can be categorized into binary semaphores (similar to “flags”, … Read more
