工业ＰＣ一般都有标准１０１键键盘接口，但大多数工业ＰＣ使用的是非标准、非编码键盘。因此开发一种既能通过标准ＰＣ键盘接口与工业ＰＣ通信，又能驱动非标准键盘的通信接。是十分有意义的。本文给出了一种用８０５１单片机实现上述接口的方法。
Industrial PCs generally have a standard 101-key keyboard interface, but most industrial PCs use non-standard, non-coded keyboards. Therefore, a communication interface that can communicate with an industrial PC through a standard PC keyboard interface and drive a non-standard keyboard can be developed. Is very meaningful. This article gives a method of using the 8051 microcontroller to achieve these interfaces.
