摘要

Universal Serial Bus (USB) as a new interface especially on Personal Computer (PC) has become a standard for interfacing many devices to PC such as printer, scanner, mouse, webcam, etc. In this paper, a device that can be recognized by USB host and communicate through USB port correctly was developed. It has been implemented by making an adapter therefore IBM PS/2 keyboard could be recognized and operated in a USB environment. The device used a PDIUSBD12 USB interface IC which handle USB protocol and an AT89C2051 microcontroller which handle all incoming or outgoing data from and to PDIUSBD12 or keyboard. The device has been tested and proven capable of handling enumeration process and transfer data from keyboard to PC via a USB port. Although the device didn\u27t support all functions of the keys, but the main keys worked normally on pressing one key or even combination keys.Keywords : Universal Serial Bus, PS/2 Keyboard Adapter to USB port, PDIUSBD12.
