For this, every task descriptor inside the RTOS has a cumulative counter which adds the timer ticks spent for that task. The current timer tick count are memorized when a task gets the CPU time and again when the RTOS switches out that task.

How long is a "tick" in FreeRTOS? - Stack Overflow

WebAug 14, 2024 · Then a tick is not 1ms long, but 1.25ms or 2.5ms respectively, which is an integer multiple. Most OS'es have the systick rate as a configuration in a header file, or perhaps in the CMSIS library sometimes as well. You will probably still need an OS (software) timer to handle the task activation though. WebOct 22, 2024 · The FreeRTOS tick frequency is set by default to 100Hz, meaning a tick will occur every 1ms. Therefore calling vTaskDelay (1) will block the calling task by 1ms.

The OS Tick API is an interface to a system timer that generates the Kernel Ticks. All Cortex-M processors provide an unified System Tick Timer that is typically used to generate the RTOS Kernel Tick. The Cortex-A processors do not implement an unified system timer and required a device specific implementation.
