问 我用tbccr1触发adc12序列单次转换，tb0中断处理a/d结果，发现a/d只触发一次
个位大虾帮我找一下原因！！谢谢
void init_ad (void)
{ ADC12CTL0&=~ENC;//DISABLE A/D,please notice the low error;
ADC12CTL0|=ADC12ON+MSC+SHT0_1+SHT1_1;
ADC12CTL1=SHP+SHS_3+ADC12SSEL_2+CONSEQ_1;//ADC12DIV_1,MCLK/2=4M,TIMEB1 //OUTPUT TRIG THE SAMPLING OF AD
ADC12MCTL0=INCH_0;//UA
ADC12MCTL1=INCH_1;//IA
ADC12MCTL2=INCH_0;//ua
ADC12MCTL3=INCH_2;//UB
ADC12MCTL4=INCH_3;//IB
ADC12MCTL5=INCH_2;//ub
ADC12MCTL6=INCH_4;//UC
ADC12MCTL7=INCH_5;//IC
ADC12MCTL8=INCH_4;//uc
//ADC12MCTL10=INCH_11;
ADC12MCTL9=INCH_6+EOS;//offset
ADC12CTL0|=ENC;//ENABLE A/D
}
void init_tb(void)
{ TBCTL=TBSSEL1+TBCLR;//TBCLK=smCLK,STOP TB
TBCCTL0=CCIE;
TBCCR0=1667;
TBCCTL1=OUTMOD_3;
TBCCR1=1400;
TBCTL|=MC_1;
