单次采样试过了没问题可是改成多路以后中断都进不去了！哪个大神帮着看看哪的毛病！谢谢了
程序有电多我只拷贝了我更改的部分！
1.先是初始化 A12 A13 A14 A15
ADC12_B_configureMemoryParam configureMemoryParam = {0};
configureMemoryParam.memoryBufferControlIndex = ADC12_B_MEMORY_0;
configureMemoryParam.inputSourceSelect = ADC12_B_INPUT_A12;
configureMemoryParam.refVoltageSourceSelect =
      ADC12_B_VREFPOS_AVCC_VREFNEG_VSS;
configureMemoryParam.endOfSequence = ADC12_B_NOTENDOFSEQUENCE;
configureMemoryParam.windowComparatorSelect =
      ADC12_B_WINDOW_COMPARATOR_DISABLE;
configureMemoryParam.differentialModeSelect =
      ADC12_B_DIFFERENTIAL_MODE_DISABLE;
ADC12_B_configureMemory(ADC12_B_BASE, &configureMemoryParam);

//ADC12_B_configureMemoryParam configureMemoryParam = {0};
configureMemoryParam.memoryBufferControlIndex = ADC12_B_MEMORY_1;
configureMemoryParam.inputSourceSelect = ADC12_B_INPUT_A13;
configureMemoryParam.refVoltageSourceSelect =
ADC12_B_VREFPOS_AVCC_VREFNEG_VSS;
configureMemoryParam.endOfSequence = ADC12_B_NOTENDOFSEQUENCE;
configureMemoryParam.windowComparatorSelect =
ADC12_B_WINDOW_COMPARATOR_DISABLE;
configureMemoryParam.differentialModeSelect =
ADC12_B_DIFFERENTIAL_MODE_DISABLE;
ADC12_B_configureMemory(ADC12_B_BASE, &configureMemoryParam);

//ADC12_B_configureMemoryParam configureMemoryParam = {0};
configureMemoryParam.memoryBufferControlIndex = ADC12_B_MEMORY_2;
configureMemoryParam.inputSourceSelect = ADC12_B_INPUT_A14;
configureMemoryParam.refVoltageSourceSelect =
   ADC12_B_VREFPOS_AVCC_VREFNEG_VSS;
configureMemoryParam.endOfSequence = ADC12_B_NOTENDOFSEQUENCE;
configureMemoryParam.windowComparatorSelect =
   ADC12_B_WINDOW_COMPARATOR_DISABLE;
configureMemoryParam.differentialModeSelect =
   ADC12_B_DIFFERENTIAL_MODE_DISABLE;
ADC12_B_configureMemory(ADC12_B_BASE, &configureMemoryParam);

  //ADC12_B_configureMemoryParam configureMemoryParam = {0};
  configureMemoryParam.memoryBufferControlIndex = ADC12_B_MEMORY_3;
  configureMemoryParam.inputSourceSelect = ADC12_B_INPUT_A15;
  configureMemoryParam.refVoltageSourceSelect =
   ADC12_B_VREFPOS_AVCC_VREFNEG_VSS;
  configureMemoryParam.endOfSequence = ADC12_B_ENDOFSEQUENCE;
  configureMemoryParam.windowComparatorSelect =
   ADC12_B_WINDOW_COMPARATOR_DISABLE;
  configureMemoryParam.differentialModeSelect =
   ADC12_B_DIFFERENTIAL_MODE_DISABLE;
  ADC12_B_configureMemory(ADC12_B_BASE, &configureMemoryParam);

ADC12_B_clearInterrupt(ADC12_B_BASE,
                        0,
                        ADC12_B_IFG3
                        );
//Enable memory buffer 0 interrupt
ADC12_B_enableInterrupt(ADC12_B_BASE,
                        ADC12_B_IE3,
                        0,
                        0);

2.定时器里转换
#if defined(__TI_COMPILER_VERSION__) || defined(__IAR_SYSTEMS_ICC__)
#pragma vector=TIMERB0_VECTOR
__interrupt
#elif defined(__GNUC__)
__attribute__((interrupt(TIMERB0_VECTOR)))
#endif
void TIMERB0_ISR(void)
{

//Enable/Start sampling and conversion
/*
   * Base address of ADC12B Module
   * Start the conversion into memory buffer 0
   * Use the single-channel, single-conversion mode
   */
ADC12_B_startConversion(ADC12_B_BASE,
                        ADC12_B_MEMORY_0,
ADC12_B_SEQOFCHANNELS);
// __bis_SR_register(LPM3_bits | GIE); // Wait for conversion to complete
// __bic_SR_register(GIE);

}
3.AD中断

这个手册上还要有写，主要是寄存器的值的配置，这个还是自己看看吧，对自己也是一种提高，老实说，在论坛上贴程序的，很多是解决不了问题的，就像我一样，即使这个芯片我用过，我也不会再回去翻芯片手册一点点的对照程序检查
