一种实用的无线键盘鼠标转换器的设计

The design of a practical wireless converter for keyboard and mouse

介绍了利用数字无线通信模块和单片机,实现了一种将有线键盘鼠标转换为无线键盘鼠标的转换器。硬件构成包括发射器和接收器两部分。发射器主控芯片采用AT89C2051单片机,接收器主控芯片采用EZ-USBFX2单片机CY7C68013,无线通信部分采用基于nRF2401芯片的无线收发模块。软件部分为两块单片机的固件设计。该转换器利用现有的有线PS/2键盘鼠标,低成本地实现了无线键盘鼠标,因而存在着很大的实用价值。

On the basis of digital wireless communication module and micro control unit（MCU）, a device converting the wired keyboard and mouse into wireless ones is introduced in this paper, which is composed of a transmitter and a receiver.The transmitter adopts AT89C2051 as the main control MCU while the receiver adopts EZ-USB FX2 CY7C68013.The wireless transceiver module based on nRF2401 chip was adopted for the wireless communication part.The software part includes the firmware design of two pieces of MCU.Because the wired PS/2 keyboard and mouse can be used, the implemented converter can find its extensive applications at very low cost.
