代码说明:

这只是demo 用于usb通讯,这是通过系统api函数来枚举获取并打开usb设备进行通讯,实现上位机和下位机通过usb口进行通讯,以往都是一串口通讯,这提高了通讯的速度。

下载说明:请别用迅雷下载,失败请重下,重下不扣分!

    This book is meant to help the reader learn how to program in C. It contains a tutorial introduction to get new users started as soon as possible, separate chapters on each major feature, and a reference manual. Most of the treatment is based on reading, writing and revising examples, rather than on mere statements of rules. For the most part, the examples are complete, real programs rather than isolated fragments. All examples have been tested directly from the text, which is in machine-readable form. Besides showing how to make effective use of the language, we have also tried where possible to illustrate useful algorithms and principles of good style and sound design.
