STM32 FreeRTOS: FreeRTOS Scheduler
STM32 Microcontroller and FreeRTOS Development The scheduling algorithm is the software routine that decides which ready state task to transition into the running state. Round Robin: this scheduler will ensure tasks that share priority are selected to enter the running state in turn. The Round Robin scheduling algorithm in FreeRTOS does not guarantee time is…
