In order to meet the requirement of software timer in microcontroller development system,an efficient software timer is designed and implemented. A number of software timers are achieved based on a single hardware timer,and can be used as a module embedded into the software. The design idea and implementation method are mentioned in details.The results of experimental tests and application example show that the system is with controllable-error and good property,and meets the application requirements of microcontroller development system.
