how do i add ten seconds delay before acceleration measurement is passed to RF USB Access point?

jeremy,

There are a few of different ways to do it:

1.  __delay_cycles(x);  whrere x is the number of clock cycles to wait. experiment with it.

2. you can use an empty for loop to loop until you would like to continue: i.e for(x=0 ; x<itterations; x++) . itterations is the number of times you would lilke to loop.

I would reccommend option one. Based on your clock frequency you should be able to calculate how many cycles is needed for a 10 sec delay.

What I've done in projects where there was a 32KHz crystal connected to XT1 is to set one of the timers, A or B, to be sourced by ACLK and set the timer to be in count up mode. Set a compare register for 32768.  This is essentially Davids option one.

      TACTL = TASSEL0+TACLR;       // Set timer A to be sourced by ACLK(32KHz)

      TACCR0 = 32767;

      TACTL |= MC_1;                            // Start timer in continuous mode

       while ( !TACCTL0 & CCIFG );    // wait for timer to expire

      // if here, then one second has gone by
