LED光柱显示器实现高精度显示的软件方法

摘要

本文详细讨论了利用LED光柱显示器实现1‰精度显示的原理和软件实现方法，并给出了关键模块的MCS－51单片机实现程序。这种方法以光柱显示器作为百分比显示的显示调节仪表中，具有很高的实用价值。%This paper discusses the 1‰ accuracy display theory and software implementat-rnion by means of LED light columns,and presents the MCS-51 microprocessor programmof of some key modules.This method is valuable in practice for the application dispay-regulating instruments with LED light columns as its percentage display.
