利用单片机设计仿真键盘的原理及与PC机的通信

Design of Emulational Keyboard with SCMand Communication with PC

嵌入式计算机系统的飞速发展,使得工业领域的自动控制不再局限于使用单片机,已采用功能强的微机系统实现控制.但是做为微机系统的标准输入设备键盘却因体积大,按键多而不适合简单的现场控制,针对这一情况,笔者利用单片机设计了PC机仿真键盘,这种键盘结构简单,成本低廉,适合工业现场的输入控制,并与微机系统具有良好的兼容性.

With the development of embedded computer system,factories use not only simply SCM,but also computer system,but standard keyboard is large and needs many keypress.In this paper,we designed a emulational keyboard with SCM,its keyboard' configuration is simple and it's cost is cheaper,it is fitted for factories,and this keyboard is compatible with PC.
