 　　采用硬件：

MP416（16位AD，5V/10V/±5V/±10V量程）

 　　设计思路：

1. 使用MP416_AD()函数，采用通道1测试，基准板输出为±200mV,±2.5V,±10V,GND

等，考虑测量精度，使用MP416的±5V量程测量基准板输出±200mV,±2.5V电压；使用MP416的±10V量程测量基准板输出±10V电压。即通过键盘输入gain值2或3来选择合适量程。

2. 不采用MP416_AD()函数测量平均值，故取测量1次。

3. 采样十次（便于分析测量误差）将值存入数组以便处理。

4. 测量值包括AD采样最大值，最小值；电压最大值、最小值，平均值；最大跳字，及对应最大电压变化值。

5. 按回车键，可以继续测量；G键位重新选择量程；ESC或Q键退出。

MP416 (16 Wei AD, 5V/10V/± 5V/± 10V range)



　design ideas:



1. Use MP416_AD () function, using channel 1 test, the base plate output is ± 200mV, ± 2.5V, ± 10V, GND



And so on, consider the measurement accuracy, use the MP416 measuring range of ± 5V output of the base plate ± 200mV, ± 2.5V voltage　the use of MP416 measuring range of ± 10V output ± 10V voltage of the base plate. Input gain value through the keyboard 2 or 3 to select the appropriate range.



2. Do not use MP416_AD () function is measured, on average, so they chose a time measurement.



3. Sampled 10 times (to facilitate analysis of measurement error) will be deposited into an array of values for processing.



4. Measured values, including AD sample maximum, minimum　voltage maximum, minimum, average　the biggest jump characters, and the corresponding changes in the value of maximum voltage.



5. Press Enter key, you can continue to measure　G keys re-select
