一,定时器初始化代码如下
Timer_Params_init(&timeSleep_params);
timeSleep_params.period = WAKEUP_TIMES * 1000 * 1000; //
timeSleep_params.periodUnits = Timer_PERIOD_US;
timeSleep_params.timerMode = Timer_CONTINUOUS_CALLBACK;
timeSleep_params.timerCallback = timerCallback;
timerSleep = Timer_open(CONFIG_TIMER_0, &timeSleep_params);
if (timerSleep == NULL)
{
/* Failed to initialized timer */
while (1) {}
}
MyWakeUpT_CB.whichStandby = 0x21;
if (Timer_start(timerSleep) == Timer_STATUS_ERROR)
{
/* Failed to start timer */
while (1) {}
}
二,定时器回调函数如下
void timerCallback(Timer_Handle myHandle, int_fast16_t status)
if (myHandle == timerSleep)
{
//do some things
Timer_stop(timerSleep);
}
}
三,更改定时时间
Timer_stop(timerSleep);
Timer_setPeriod(timerSleep, Timer_PERIOD_US, time);
Timer_start(timerSleep);
四,现象
多次操作后会出现到达预定时间不进入定时器中断现象.
