[参考译文] MSP430F5325：我想按 ADC12选择2个输入通道、但一个通道不起作用。

代码：

void AdcInit (void)
｛
   ADC12CTL0 = ADC12SHT02 + ADC12ON；        //采样时间、ADC12打开
   ADC12CTL1 = ADC12SHP；                    //使用采样计时器
   ADC12MCTL0 = ADC12INCH_2；              //选择输入通道2
   ADC12MCTL1 = ADC12INCH_3 | ADC12EOS；    //选择输入通道3
   ADC12IE = ADC12IE0；                      //启用中断
   ADC12CTL0 |= ADC12ENC；
   P6SEL |= BIT2 | BIT3；                    // P6.0 ADC 选项选择
｝

#pragma vector = ADC12_vector
_interrupt void ADC12_ISR (void)
｛
   uint16nTemp                     ；

   switch (__evo_in_range (ADC12IV、34))
   ｛
   情况 0：中断；                          //向量 0： 无中断
   情况 2：中断；                          //矢量 2： ADC 溢出
   情况 4：中断；                          //矢量 4： ADC 时序溢出
   情况 6：                                 //向量 6： ADC12IFG0
       nTemp                  = ADC12MEM0；
       tracelog ("ADC12MEM0 =%d\n"、nTemp)；

       nTemp                  = ADC12MEM1；
       tracelog ("ADC12MEM1 =%d\n"、nTemp)；

       _BIC_SR_REGISTER_ON_EXIT (LPM0_BITS)；  //退出活动 CPU
       中断；
   案例 8：                                 //向量 8： ADC12IFG1
       中断；
   默认值：break；
   ｝
｝

P6.2成功、但 P6、3失败、ADC12MEM1为零。 但 P6.3电压为3.3V
