【正文】 M systems need a lot of keyboard input device, in a variety of singlechip microputer system is always an essential part of the. The line scan input method simple still has great significance, without the need for plicated micro processing module, it is a very important way of manmachine munication.Based on the 4 * 4 matrix keyboard input device as an example, the use of the knowledge, a simple input device reliability is established, through the principle of design concise representation of keyboard input device and line scanning method, and a good grasp of, the final harvest.Practice shows that, the simple 4 * 4 matrix keyboard input device due to irrational use of resources, information processing algorithm efficiency is low, still need a lot of learning and its improvement.Key words: SCM，Matrix keyboard，4 * 4 keyboard，Simple，Line Scanning MethodII基于單片機(jī)的44矩陣鍵盤輸入1引言本設(shè)計(jì)提出了用AT89C51單片機(jī)為核心控制元件，設(shè)計(jì)一個(gè)簡(jiǎn)易的44矩陣鍵盤輸入裝置，本方案以AT89C51單片機(jī)作為主控核心，與晶振、數(shù)碼
