摘要
移动数据的交换和存储是近年来的研究热点,随着USB技术数据交换和存储技术的飞速发展,对移动数据应用领域产生了影响深远。脱离传统的PC平台,实现移动端之间的USB通信成为了当前的研究热点,如何在嵌入式领域实现USB的主机通信成为了不可避免的问题。基于STM32F767自带的USB OTG模块,采用软件分层结构化的设计思想,搭建了USB主机通信的程序框架,并详细研究了各层驱动的功能以及如何利用程序代码进行实现,实现了两个USB设备之间稳定高效的数据交换。
Mobile data exchange and storage is a hot spot in recent years.With the rapid development of USB technology,it has a far-reaching impact on mobile data applications.From the traditional PC platform,the realization of USB communication between mobile terminals has become a hot topic of research.How to implement USB’s host communication in the embedded field has become an inevitable problem.The USB OTG module with STM32 F767 based on the design ideas of hierarchical structured software,build a framework of USB host communication program,and a detailed study of the driver function and how to use the program code to achieve the realization of the USB between the two stable and efficient data exchange equipment.
