采集AIN0和AIN1的信号，通过可调电阻，使输入的模拟信号发生改变，来进行A/D转换。为保证数据的准确性，通常采集10次以上，在求平均值。A/D转换器采集AIN0和AIN1的信号,并显示出来。-AIN1 acquisition and AIN0 signal, through an adjustable resistor, so that the analog signal input to change, to carry out A/D conversion. In order to ensure the accuracy of the data is usually collected 10 times more than the average in the order. A/D converter and acquisition AIN0 signals AIN1 and displayed.
