Description: 摘 要： 本文件是C8051单片机DA测试实验程序；使用外部22.1184MHz晶振.
功能：定义 A ~ F 为功能键。
按\"A\" 键，输出250HZ的方波，按\"B\" 键，输出250HZ的正弦波形，按\"C\" 键，输出250HZ的三角波，
按\"D\" 键，输出250HZ的锯齿波。用示波器在J6（DAC0）观测结果，使用串口观测按键信息。-Abstract : This document is C8051 MCU DA laboratory procedures; use of external 22.1184 MHz oscillator. Function : A definition of the F-key functions. By the "A" key, and the output of 250 square 9999, according to the "B" button, and the output of 250 HZ sinusoidal shape, "C" key, and the output of 250 HZ triangular wave, according to the "D" button, and the output of the Sawtooth 250 9999. Oscilloscope with the J6 (DAC0) observation, the use of serial observation keystroke information.
