是pwm触发，但是我没打开呢，我软件触发采样的到6个数据以后再打开，pwm触发。我初始化完成后，我在ccs里面就看到ADCRESULT有更新啊，没触发怎么在不断转换。。。。！？

PWM模块那边初始化设置是什么信号产生SOC信号的呢？TBCTR = ？建议检查下是不是PWM模块产生了SOC信号。

初始化后为何ad就一直在转换。

AdcRegs.ADCSOCFRC1.all = 0x00FF;

while(AdcRegs.ADCSOCFLG1.all != 0){};

软件触发，我在while前设置了个断点，看了一下寄存器，ADCSOCFRC1寄存器并没有被置1

回复 yongliang li1:

你检查一下PWM的寄存器是否有在计数。
