WebJan 21, 2024 · The SysTick timer is intended for use by an RTOS. It normally runs at the same frequency as the core. Set configCPU_CLOCK_HZ to the frequency the core will be executing at, then configTICK_RATE_HZ to the rate at which you want the RTOS tick interrupt to execute at, and the RTOS will setup the SysTick timer for you when the scheduler is … http://www.learningaboutelectronics.com/Articles/Systick-reload-value-register-calculator.php
