BES 定时器使用记录
1.配置回调
根据名字“cpu_usage_timer” 配置回调“cpu_usage_timer_handler”
osTimerDef(cpu_usage_timer, cpu_usage_timer_handler);
2.创建定时器
osTimerCreate(osTimer(cpu_usage_timer), osTimerPeriodic,
NULL);
3.使用定时器
osTimerStart(cpu_usage_timer_id, CPU_USAGE_TIMER_TMO_VALUE);
4.停止定时器
osStatus osTimerStop (osTimerId timer_id)
