本文件是AD测试实验；测试前需要对管脚复用的电压基准进行设置，将JP10的2，3脚短接，1脚空出。AD输入端子(J10)可输入4路AD(ADC0--ADC3)，另有1路可测量片内温度，5路采样值都通过串口发送出去，在串口调试助手上看观察其值。4路AD中ADC0可通过跳线器(JP5)“ADJ_VOL”（1，2脚短接）与板上电位器相连，通过手动调VR1可以观察到电压值的变化-This document is the AD test experiment　testing is required before reuse of the voltage reference pin is set, the JP10 shorted 2,3 feet, 1 foot empty. AD input terminals (J10) to enter 4 AD (ADC0- ADC3), and 1 way to measure chip temperature, 5-way samples are sent through the serial port, serial port debugging assistant in terms of observed values. 4 AD by the ADC0 jumper (JP5) " ADJ_VOL"　(1,2 pin shorted) is connected with the on-board potentiometer, VR1 can be observed by manually adjusting the voltage changes
