基于USB接口技术的信号发生器的设计

The Design of a Signal Generator Based on USB Interface Technology

该文论述一种专用信号发生器的设计过程。该设计的特点是运用USB接口技术将存放在大容量U盘中的原始数据比特流复现。整个系统分为两个模块,数据采集模块和数据发送模块。系统的设计思想是以单片机为核心运用USB接口芯片CH375对U盘存储的大容量数据进行采集,然后通过单片机将数据以一定的速率发送。

This paper is mainly about the designing process of the signal generator.The characterized of the design by the use of USB interface technology to repeat quondam data stream deposited mass-storage USB disk.According to the design demand,it contains two modules: transmitter module and collection module.The method adopted in this article is to collect the USB disk storage of large amounts of data with USB interface CMOS chips CH375.the core in this design is the MCU.And then the data is transmitted in the rate of certain by the MCU.
