Web/* Use the SysTick current-value register to determine the number of * SysTick decrements remaining until the next tick interrupt. If the * current-value register is zero, then there are actually * ulTimerCountsForOneTick decrements remaining, not zero, because the * SysTick requests the interrupt when decrementing from 1 to 0. WebThe above code sets up the internal clocks in the device. The next step is to enable the systick timer. The function initSysTick does this. The STM32F0 processor has a calibration register that contains the value 6000. If this value is used as for systick counter reload then an interrupt will be generated every millisecond.
