说明：此程序使用标准PS2键盘输入，LCD1602液晶屏输出显示。此样例仅作测试使用 晶振使用12M或者11.0592M,本键盘使用部分字母和数字测试，其他按键不能使用，用 户可以自行扩展。由于开发板和程序的各种参数，程序中没有使用奇偶校验，不保证没有 误码,校验程序请自行添加。-Description: This program uses the standard PS2 keyboard input, LCD1602 LCD output display. This sample is only used for testing the use of crystal 12M or 11.0592M, this keyboard to use part of letters and numbers tests, other buttons can not be used, users can expand their own. As the development board and procedures for various parameters, the program does not use parity, does not guarantee that there is no error, verification procedures to add your own.

数字电路抗干扰： 在电子系统设计中，为了少走弯路和节省时间，应充分考虑并满足抗干扰性 的要求，避免在设计完成后再去进行抗干扰的补救措施。-Digital circuit interference: In the electronic system design, for less detours and save time, should take fully into account and meet the requirements of anti-interference, to avoid later in the design of anti-interference to carry out remedial measures.

此程序是利用51单片机，控制蜂鸣器接口高低电平，让其发出歌声。-This procedure is the use of 51 single-chip microcomputer to control the buzzer interface high-low, so the issue of voice.
