As i understand your C-code, the division by 8 for the timer A is too much. Try it without the division by 8. Best regards

Has anybody had any experience trying to use a 100kHz xtal instead of the usual 32kHz? It looks like I'm getting a subharmonic. Thanks, Garst void setup_timerA(void) { unsigned temp; #ifdef _SHOW_YELLOW_LED_ /*P1.6 is also connected to the IrDA CD pin*/ P1SEL |= BV(6); P1DIR |= BV(6); #endif //Assumes ACLK = 100kHz, MCLK = 3.6864MHz // set up timer A for 250us SAMPCON to ADC12 TACTL = TASSEL_ACLK + MC_UPTO_CCR0;// + ID_DIV8; TACCR0 = 25; //RESET when TAR==CCR0 TACCR1 = 22; //SET when TAR==CCR1 TACCTL1 = OUTMOD_SET_RESET; //Mode 3: set_reset /*Start Timer*/ TACTL |= TACLR; TACTL &= ~TACLR; } ------------------------------------------------------- This SF.net email is sponsored by: SF.net Giveback Program.
