Hi,Mark Thank you for your good way!! I read manual said that we can use TamerA OUTPUT UNIT1 to trigger ADC12 conversion like this
TACTL = TASSEL_2+MC_2; // Timer_A setup TACCTL1 = OUTMOD_3; // CCR1 setup TACCR1 = 0x0fff; // Compare value ADC12CTL0 = ADC12ON+SHT0_2; // Turn on ADC12, set sampling time ADC12CTL1 = SHS_1+SHP; // TAOUT.1 triggers sampling timer ADC12CTL0 |= ENC; // Enable conversions ADC12CTL0 |= ADC12SC; // Start conversion but this doen's work to my code , it never stop by ADC interrupt routine. What's the reason? Thank you! Regards Zhengsu
