Therefore to get a SysTick of 1ms using a 24 MHz BUS_CLK, we would use newperiodncnt = BUS_CLK/SysTickPeriod = 24,000,000/.001 = 24,000 If you want a different SysTick period substitute your new value into SysTickPeriod and make sure it doesn't exceed 24-bits. Then issue the API call: …

WebThe SysTick_Config function automatically starts the System Timer, sets the countdown value as its only input, and enables the SysTick interrupt. By dividing the core frequency by 1,000, we are saying that we want each SysTick to occur every millisecond. For example, if the clock is running at 32MHz, the countdown value is 320,000. http://www.openrtos.net/Using-FreeRTOS-on-Cortex-A-proprietary-interrupt-controller.html
