摘要
本文首先将USB与其他常用总线在传输速率等方面做了比较,总结了USB主要优势特点。然后介绍了USB接口芯片PDIUSBD12,并通过一个微控制器数据采集系统利用PDIUSBD12与PC机进行互连的接口实例从硬件设计、固件设计、设备驱动程序设计和用户软件的设计四个方面阐述了基于USB的实时数据采集系统的设计与实现方法。
In this paper we firstly compared USB and other common buses in the transport speed and ete, summarized the superiorities of USB. And then we introduced USB interface chip PDIUSBD12. Then we expounded the design and realization ways of realtime date acquisition system based on USB in the designing of hardware, firmware, device drive program and user program of an interface example between PDIUSBD12 and PC in a date acquisition system with MCU.
