基于DSP的USB主从机双向通信接口设计

Design of USB-HOST & DEVICE Two-orientation Communicating Interface Based on DSP

介绍了一种基于DSP的USB主从机双向通信设计方案,实现DSP与PC机、DSP与移动存储器的双向通信,以及两种方式的自动切换,并给出了USB主从机设计的硬件、软件的实现方法。实验结果表明了该方案的可行性和实用性,满足了设计的要求。

This paper introduces a kind of two-orientation communicating design plan of USB HOST and DEVICE based on DSP,has realized DSP and USB-HOST,DSP and USB-DEVICE two-orientation communication,and two orientations can be switched over automatically.It also has provided the hardware and software implementation method designed of the USB-HOST ＆DEVICE.The experimental results show the validity and practicability of this scheme,and satisfy the request of design.
