摘要
随着USB技术的不断发展,以USB进行数据传输的方式将得到越来越广泛的应用。以实际设计的系统为背景,论述了ARM7系统中USB工作的基本原理和过程,利用USB作为数据的传输接口,基于LPC2148和AD9826设计了一个数据采集系统,并给出了具体的相关实验结果。
With the development of USB technology, data communication with USB will be used in wider areas. The principle and process of ARM7 system＇USB are illustrated in the background of actual system design, a data acquisition system with USB interface based on LPC2148 and AD9826 is designed, the concrete results of interrelated experiment are showed in this article.
