Timer in MyStarNetwork Demo

moti — Thu, 03 Jan 2008 05:15:30 GMT

We tried to use this function: (in 13213 evk board in MyStarNetwork Demo program)

TMR_StartSingleShotTimer(mSoftTimerId_c, mWaitInterval_c, App_IntervalTimeoutHandler);

but we didnt see any delay after it !

what can we change or what do we need to add

thank you

moti

see below the code

LCD_ClearDisplay();
LCD_WriteString(1,"Press any key");
LCD_WriteString(2,"to start.");

TMR_StartSingleShotTimer(mSoftTimerId_c, 4000_c, App_IntervalTimeoutHandler);

LCD_ClearDisplay();
LCD_WriteString(1,"are you");
LCD_WriteString(2,"sure.");

Moti,

I think you are misunderstanding how the TMR_StartSIngleshotTimer() works.

It is not a "blocking mode" delay function.

It starts a timer that expires after an interval. When the timer expires the callback is called.

Also you should not use the Callback that is used by another timer, you should make your own - e.g.

static tmrTimerID_t mDelayTimerId;

void testfunction(void)

{

mDelayTimerId = TMR_AllocateTimer(); // should only be done once!!

LCD_ClearDisplay();
LCD_WriteString(1,"Press any key";
LCD_WriteString(2,"to start.";

TMR_StartSingleShotTimer(mDelayTimerId_c, 4000_c, DisplayTimeoutHandler);

}

void DisplayTimeoutHandler((uint8_t timerID)

(void) timerID;

LCD_ClearDisplay();
LCD_WriteString(1,"are you";
LCD_WriteString(2,"sure.";

}

Look in the Beestack Generic app for example on how the timer can be used to drive delays between different states.

BR,
