CC3200 ADC问题

Other Parts Discussed in Thread: CC3200

您好，请问CC3200的ADC采样频率可以设置吗？ 我翻了半天API还有手册，并没有设置的地方

设置ADC管脚后，拿示波器观察ADC引脚，发现是62.5K Hz的脉冲，这个对信号采样有影响吗？

谢谢！

    Hi Weicheng,

    您好！

    关于CC3200的ADC sample rate,确实没法设置，是固定的62.5KSPS。 谢谢!

    用的是官方给的sdk例程里面的adc

    我没有接任何输入信号，但其adc采集有电压是有的

    这是怎么回事

    请技术人员给出解答
