Article Introduction：The working principle of timers can be divided into two types: hardware timers and software timers. The working principle of the hardware timer is that the clock signal source provides a stable clock signal as the reference of the timer. The counter starts counting from a preset value and is incremented every time the clock signal arrives. When the counter reaches the preset value, the timer will trigger an interrupt signal to notify the interrupt controller to process the corresponding interrupt service routine. In the interrupt service routine, some predetermined operations can be performed. The working principle of the software timer is implemented through library functions or system calls provided by the programming language or system, etc.
