This paper presents a novel keyboard data transmit interface based on PC 104. It focuses on how to transmit the data between the keyborad data interface to PC 104 and the design about the interface circuit and function. In the paper, it provides a way to design the keyborad data managing software and the corresponding block. You can transmit the data bits with any length usede the keyboard data transmit interface , and the special keyboard has a lot of application i some micro navigation system.
