MSP430FR2353 AD多通道采集 现在采集通道8 和内部温度通道A12 只采集这两个通道求指点下，以下是我的配置读取参考官方例子，参考电压内部2.5V，不顺序采集AD ，只采集指定的通道AD的采集

您现在程序运行结果如何？

那您上述程序运行如何？是自己制作的板子？建议先运行下TI例程，看是否能正常采集转换

您可以参考下面的例子，是采集A2/A1/A0, 使用internal 2V Ref

采集到的数据很乱， 下面是我采集到的数据 感觉[0] 很像我内部温度的采集 [9] 很像我A8通道的采集，是不是我哪里配置的错了，还是别的什么？求指点下，

[10]unsigned int 375 0x002014
[11]unsigned int 1038 0x002016
[12]unsigned int 1053 0x002018
刚才你说的配置A8 做了如下配置
ADCMCTL0 = ADCINCH_12 | ADCINCH_8 | ADCSREF_1; // A8 ADC input select; Vref=2.5V
采集的结果就是上面的

那您单独测A8或者A12呢？是否正常？

我参考了这个例子
// Configure ADC A1~2 pins
P1SEL0 |= BIT1 + BIT2;
P1SEL1 |= BIT1 + BIT2;
这行配置好像没对A0 进行选择吧，我看了寄存器是没有，
ADCMCTL0 |= ADCINCH_2 | ADCSREF_1; // A0~2(EoS); Vref=2V
咱们通道只指定了指定的2 通道循环从 0 1 2 采集，有没有办法不循环呢，指定几个通道进行循环， 比如 2 4 8 三个通道进行循环 ，这样的话该如何进行配置，板子是我们自己的制作的，只是，我现在进行简单的多通道采集，然后单片机直接接地采集到数据就是错误的
