无线USB通信装置的研制

Design of Wireless USB Communication Device

为解决有线USB(Universal Serial Bus)设备放置距离近且放置混乱等问题,研制了一款既包含点对点无线USB装置也包含一点对多点的无线USB集线器装置,可以实现无线打印功能。该系统以S3C2440 ARM9处理器为控制核心,采用Linux操作系统,无线部分采用WiFi(Wireless Fidelity)实现。测试结果表明,该装置可以达到较好的无线打印效果。

In order to resolve the problem that the cable USB （Universal Serial Bus） devices are placed close and chaotic, we design a wireless usb device. The device can be used as a point-to-point device or a point-tomuhipoint device, which can achieve the function of a wireless printer. The system is based on S3 C2440 ARM9 processor and Linux operaion system. The wireless communication is based on the WiFi （Wireless Fidelity） technology. The experiment results showed that the device could achieve wireless-printing function well.
