单片机软定时器

一直想在单片机上实现一个像MFC和WPF一样的软定时器，花了点时间终于写出来了，使用时需把timer_run函数放到定时器中断服务函数里面

typedef struct _TIMER{unsigned char isEnable;unsigned int  count;unsigned int  countNeed;void (*func)();}TIMER;void timer_Run(TIMER *timer){if(timer->isEnable){timer->count ++;if(timer->count == timer->countNeed){timer->count = 0;timer->func();}}}void startTimer(TIMER *timer){timer->count = 0;timer->isEnable = 1;}void stopTimer(TIMER *timer){timer->isEnable = 0;timer->count =0;}
