本文首先扼要地介绍了智能仪器键盘及键盘管理程序的一般设计方法。然后较详细地说明了键盘分析程序的状态设计法,并讨论了对状态表的有效压缩。利用状态法设计键盘分析程序的关键是状态表的设计。最后,以智能化数字电压表为例,说明键盘分析程序的一般设计步骤。
This article first outlines the general design of smart instrument keyboard and keyboard management program. Then the state design method of the keyboard analyzer is explained in detail, and the effective compression of the state table is discussed. The key to using the state method to design the keyboard analysis program is the design of the state table. Finally, take the intelligent digital voltmeter as an example to illustrate the general design steps of the keyboard analysis program.
