实验箱上的蜂鸣器发出对应的音调（中音），当同时按下L和1-7时是，蜂鸣器发出低音，同时按下H和1-7时，蜂鸣器发高音。只要按键没松开，蜂鸣器一直发声，直到松到按键。-The buzzer sounded on the test box corresponding to tone (Tenor), when at the same time when you press the L and 1-7, the buzzer sounded a bass, while pressing the H, and 1-7 when the buzzer made treble. As long as no release button, buzzer sound has always been, until the pine to the button.

本程序功能是利用单片机控制用户板上的小键盘，将按下的键通过单片机的串口发送给PC机，在PC机串口助手显示出来。用行翻转法的方法来识别输入的键盘。 二、通过单片机将键盘按下的键在LCD上显示出来。 -This procedure is the use of single-chip control functions of the user on-board a small keyboard, the keys will be pressed through the single-chip serial port sent to the PC, the PC Serial Port assistants displayed. Line inversion method used to identify the method of keyboard input. Second, through the single-chip microcomputer keyboard keys pressed on the LCD display.
