众所周知,当在计算机的键盘上按1,显示器应显示1,若显示其它则出错,所以键盘是人机准确对话的最基本环节,同样在其它仪器中,键盘也是人机正确对话、正确控制的最基本环节,所以准确接收键盘键入的信号是最基本、很关键的问题。在设计“检测信息单片机综合处理器”的过程中,我们进行了键盘接口电路的选优,按以往的键盘接口电路有专用的键盘接口芯片连接的,有按通用的接口芯
As we all know, when the computer keyboard, press the 1, the display should display 1, if the other is displayed wrong, so the keyboard is the most basic human-computer dialogue the most basic part of the same instrument in other instruments, the keyboard is the right man-machine dialogue, the correct control The most basic part, so accurately receive the keyboard typed signal is the most basic, very crucial issue. In the design of “detection information monolithic integrated processor ” in the process, we conducted a keyboard interface circuit optimization, according to the previous keyboard interface circuit has a dedicated keyboard interface chip connected, according to a common interface core
