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
