实现的模拟键盘代码，模拟ps2协议，可以与计算机相连实现键盘的功能，在keil c下开发的。-89s51 achieved through keyboard simulation code, simulation ps2 agreement with the computer keyboard connected to the functions of the c Keil under development
Abstract
A new intelligent milometer base on a microcontroller can count the sum. By taking full use of the processor 89s51 and E² PROM (AT24C02) and sensor of magnetism, it can count the sum of fully distance and the course of development.
