(1) ADC & UART: Abstract: This document is a serial AD sampling and testing procedures AD input (J7) to enter the 8 AD (AIN0- AIN7), and another 1-chip temperature measurable way, the way sampling the value of 9 through the serial port (using the serial port must be the JP3 short legs 1,2 and 3,4) sent in the serial debugging point of view to observe the value of assistants. 8-channel AD input can jump to AIN7 browser (JP1) " ADC" (1,2 feet shorter then) connected with the on-board potentiometer, VR1 can be adjusted manually through the observed changes in voltage. (2) KEY & DAC: Abstract: This document is the output DA keyboard and test procedures DA Output (J9) to output 2-way DA (DAC0, DAC1), four-way key (KEY1- KEY4, shall be provided jumper JP4), test press KEY1- KEY4, corresponding to DAC0, DAC1 output 0.5V, 1V, 1.5V, 2V.
