基于F340单片机的USB/PS2自适应键鼠设计

摘要

It's absolutely necessary devices of keyboard and mouse for computers. Keyboard and mouse with PS2 interface stil in use, while devices with USB interface are universaly used at present, especialy in military reinforce devices. The superiority of far transmission of PS2 devices signal compared with USB devices, resulting in the wide use of the PS2 devices in reinforce computer and servers equipment. This design developing a device integrated of keyboard and mouse, witch based on F340 microcontroler can be self-adaptedof USB/PS2 signal.%键盘鼠标是计算机必不可少的输入设备,目前USB接口的键盘鼠标已普遍应用,但是仍有一部分PS2接口的设备仍在使用,尤其是在军用加固设备领域,可长距离传输的优势使得PS2设备广泛应用于加固计算机、服务器等设备.本设计基于F340单片机,开发出一款集键盘鼠标于一体的一款USB/PS2自适应键鼠.
