摘要
介绍采用一种AT89C52单片机控制光标阅读机的工作,主要包括信息的采集、分析并把分析结果数据通过串行接口上传给主机进行数据处理。并重点从多个方面介绍如何节约成本,使开发出的产品性能价格比达到最大化。
An optical mark reader is introduced which is controlled by the monolithic processor AT89C52.It＇s able to collect,analyze information and transfer the result data to the host computer through serial interface for further processing.And a following discussion is developed about how to save the cost to maximize performance-price ratio.
