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.

由8051组成的单片机系统通常情况下，P0口分时复用作为地址、数据总线，P2口提供A15-A8即高8位地址，P3口用作第二功能，只有P1口通常用作I/0口。P1口是8位准双向口，它的每一位都可独立地定义为输入或输出，因此既可作为8位的并行I/O口，也可作为8位的输入输出端。当工作在输入方式时，对应位的锁存器必须先置1,才能正确地读到引脚上的信号,否则,执行读引脚指令时,若对应位的锁存器的值为0，读的结果永远为0。-By 8051, composed of single-chip microcomputer system under normal circumstances, P0 timeshare I reuse as address, data bus, P2 I provide A15-A8 high eight address, P3 mouth for the second function, I usually only P1 for I/0 I. P1 I was eight quasi-two-way port, it can be independent of each and every defined as input or output, it can be used as 8-bit parallel I/O port, can also be used as 8-bit input and output side. When the work in the input, the corresponding bit latch must first buy one in order to correctly read the signal pin, or pin the implementation of reading instruction, if the corresponding bit latch the value of 0, Reading the results of Forever to 0.
