上面是我的部分程序和AD配置，我想把g_DCVotageSample[ConversionCount] ;g_MotorCurrentSample[ConversionCount] ;改为16个数据的数组，即if(ConversionCount == 15)
{ //存16个数据
ConversionCount = 0; //在这里设置断点，查看变量的值……………
是不是还要更改AD配置：AdcRegs.ADCSOC0CTL.bit.ACQPS = 15; //设置采样时间为16个ADC时钟
AdcRegs.ADCSOC1CTL.bit.ACQPS = 15; //设置采样时间为16个ADC时钟
但是，看数据手册发现，10h,11h,12h,13h,14h,1Dh,1Eh,1Fh……等是无效配置数据，我想问：我上面的想法（还要更改AD配置）对吗？这个15应该是有效配置数据吧？
