Title: 7.滴答定时器实验 Download
 Description: Systick is just a timer, but it is put in NVIC. Its main purpose is to provide a hardware interrupt (known as a tick interrupt) to the operating system. Tick break? Here is a brief explanation. When the operating system is running, there will be a "heartbeat". It will work according to the beat of "heartbeat" and divide the whole time period into many small time slices. Each task can only run one time slice, so it has to quit to other tasks to run, so as to ensure that no task will occupy the whole system. Or give a certain time range of each timer cycle to a specific task, and various timing functions provided by the operating system are related to the tick timer. Therefore, a timer is needed to generate periodic interrupts, and it is better to keep the operating system "heartbeat" rhythm by preventing the user program from accessing its registers at will. As long as the enable bit in systick control and status register is not cleared, it will never stop.
