XVC724BE101 3BHE009017R01 is equipped with software timers in operating systems such as Linux, uC/OS, and FreeRTOS, with similar principles. The typical implementation method is to generate a fixed clock beat through a hardware timer. Each time the hardware timer interrupts, a global time stamp is incremented, and each software timer stores the expiration time.

The program needs to periodically scan all running software timers, compare each expiration time with the global clock marker to determine whether the corresponding software timer has expired. If it has expired, the corresponding callback function will be executed and the timer will be turned off.

XVC724BE101 3BHE0090017R01 and above are the implementation of a single timer. To implement a periodic timer, which means timing again after expiration, simply obtain the value of the current timestamp after executing the callback function, add the delay time as the next expiration time, and continue running the software timer.
