单片机系统的多状态显示设计

A Single-chip Microcomputer System with Multistate Display

介绍了８０３１单片机应用系统中采用三根Ｉ／Ｏ线及一组ＬＥＤ数码管进行多状态显示的设计方法，描述了改进的串行口显示方案。该方法特别适用于实时性要求不高但监控对象多、显示位数不多但显示内容复杂的场合，可大大提高设备的利用率。

This paper introduces a design of multi-state display by incorporating three I/O ports and a group of LED digital display into 8031 single-chip microcomputer system and its improved serial port display.This design is especially suitable for use in the case of multi-object monitoring,comprehensive display with less digits and lessreal-time requirement,and thereby the equipment effectiveness is much improved.
