WebIf you reserve systick for FreeRTOS, you get the best optimized/debugged code and the quickest context change (systick handler included in FreeRTOS). The other timer is for STM's HAL timer functions, but for a FreeRTOS application you're better off using the FreeRTOS time functions (vTaskDelay etc). WebSTM32F1 SysTick configuration with HAL_SYSTICK_Config () I am using the STM32F1 HAL and low-layer driver library. The 1ms SysTick timer works well. One of ST's examples computes the system clock ticks between SysTick interrupts: with SystemCoreClock=16,000,000 Hz, and uwTickFreq=1 kHz this function outputs 16,000 ticks:

WebSTM32 Delay Functions In earlier tutorials, we’ve been using the HAL_Delay utility function to get milliseconds time delay. And as we’ve discussed it’s built on the SysTick timer that ticks at a rate of 1000Hz and can only give you multiples of 1ms time delay. WebAs a result, the STM32 HAL framework gives SysTick a very high priority. However, FreeRTOS needs SysTick for its scheduler, and it requires SysTick to be a much lower …

WebBy default, the STM32Cube HAL is built around a unique timebase source which is the ARM-Cortex system timer (SysTick). However, HAL-timebase related functions are defined as weak so that they can be overloaded to use another hardware timebase source.
