(1) ADC&UART:

摘 要：本文件是AD采样及串口测试程序；AD输入端子(J7)可输入8路AD(AIN0--AIN7)，另有1路可测量片内温度，9路采样值都通过串口（使用串口必须将JP3的1，2及3，4脚短路）发送出去，在串口调试助手上看观察其值。8路AD输入中AIN7可通过跳以器(JP1)“ADC”（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。



(2) KEY&DAC:

摘 要：本文件是键盘及DA输出测试程序；DA输出端子(J9)可输出2路DA(DAC0,DAC1),四路按键(KEY1--KEY4，须设置跳线JP4)，测试时按下KEY1--KEY4，分别对应DAC0，DAC1输出0.5V，1V，1.5V，2V。-(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.
