In FreeRTOS, the task scheduler acts as the heart of the real-time operating system, managing the lifecycle and execution flow of concurrent tasks. On platforms like the STM32, launching the scheduler involves a sequence of low-level hardware and software configurations. 1. Initiating the Scheduler...
Task Execution Mechanism When a task is successfully created, it's placed in the ready queue. Once the scheduler starts, it selects the highest-priority task from this queue for execution. If multiple tasks share the same priority, they execute in the order they were created. During execution, a tas...
The Role of FreeRTOS On an STM32 running FreeRTOS, the flow from reset to task startup and multitasking operation is as follows: Reset → ② → ③: Start the first task by calling vTaskStartScheduler(), which triggers an SVC interrupt to launch the first task. ④ → ③: Multitask switching occurs via the S...
