摘要
现在,USB设备已经十分普及,尤其是HID(Human Interface Device)设备,其无需驱动的特点更是给用户带来了极大的方便。给出一种基于STC89C52RC微控制器和PDIUSBD12芯片仿真USB多点触摸设备的方法。首先介绍USB和HID的基础知识,然后详细阐述该设备的硬件设计,最后结合主机在枚举期间的请求,论述该设备的识别过程。实现的多点触摸设备无需编写和安装USB设备驱动程序,操作系统可自动识别。
In these days,USB Devices have already become very popular,especially the HID （Human Interface Device） Devices.it brings great convenience to users,owing to the feature of having no use for drivers.This paper provides a way to simulate the USB multi-touch devices based on the STC89C52RC micro control unit and PDIUSBD12 chip.It firstly introduces the basic knowledge of USB and HiD.Secondly,represent the hardware design of the device in detail.Finally,this paper discusses the software implementation process of the device,combining the requests from the host＇s enumeration process.
