说明：  1、 编程完成A/D转换程序。将ADC0804输入端的电压转换成数字量，并将该数字量显示在数码管上。 2、 编程完成D/A转换程序。使用DAC0832输出三角波、锯齿波、正弦波和方波，信号的频率自行设定，幅度均设置为3V。
(1, the programming is complete, the A/D conversion process. The voltage at the input of the ADC0804 conversion to digital, and the digital display on the digital. 2, the programming is complete, the D/A conversion program. DAC0832 output triangle wave, sawtooth, sine, and square wave signal frequency set their own rate were set to 3V.)
