1.电子琴功能 用实验板上K1~K7作为电子琴的7个按键，每个按键对应一个音符要求当按下其中一个按键，就通过P2.5口输出对应频率信号使蜂鸣器发出特定音符声音。 2.乐曲演奏 若按下K8键，完成自动弹奏“送别”歌曲。 -1. Organ function of the experimental board K1 ~ K7 as the organ of the seven buttons, each button corresponds to a note of which require that when the press of a button, on the adoption of P2.5 port output frequency signal corresponding to a specific note to the buzzer sounds . 2. Music playing, if pressed K8 button to complete the auto-play " Farewell" songs.

芯片PCF8951共有四个A/D输入通道：AD0，AD1，AD2，AD3,分别与四个电位器(R1,R2,R3,R4)连接，用以调节电位器的输出电压。其中AD0通道既可测量电位器输出电压，也可用于测量从J1插座输入的外接电压，须用开关J2加以选择。J4插座提供由PCF8591输出的时钟方波信号。SAA1064驱动四个数码管显示一路AD转换后得到的数据。-PCF8951 chip, there are four A/D input channels: AD0, AD1, AD2, AD3, respectively, with four potentiometers (R1, R2, R3, R4) connected to regulate the output voltage potential. AD0 channel which can be measured potentiometer output voltage can also be used to measure the input from the J1 socket external voltage, to be used to select switch J2. J4 socket output from the PCF8591 clock square wave signal. SAA1064 drivers of four digital display along after AD conversion data.
