[Mspgcc-users] Problems with ADC10 trigged by TA1

[Robert Scott]

Hi!

I'm working with a project where I want to trig the ADC10 at 64 kHz by 
using the Timer A Out 1.
I can't figure out what I'm doing wrong, please help me, I'm going nuts... 
or is it ballistics?
Hmmm... Anyway, here's a copy of the "important" code:
Thanks in advance for any help, any help at all! :)

  do
  {
    IFG1 &= ~OFIFG;                     // Clear OSCFault flag
    for (i = 0xFF; i > 0; i--);         // Time for flag to set
  }
  while ((IFG1 & OFIFG) != 0);          // OSCFault flag still set?

  BCSCTL2 |= (SELM_2|SELS);             // MCLK = LFXT1 (safe), SMCLK =
