以USB介面實現AD/DA訊號處理

Abstract

本篇論文主要利用Cypress 公司生產的一顆USB Version1.1的晶片---EZ-USB FX。因此晶片具有增強型的8051微處理器，其韌體可經由USB介面直接傳輸燒錄並可重新裝置列舉（Renumeration TM），因此增加了發展時的便利性。本論文目的在利用目前USB的普及性及HID(Human Interface Device)使用上的便利，以HID裝置設計一個不需使用者提供驅動程式及不需外接電源的方便性來實現類比/數位訊號擷取和測試類比/數位的擷取訊號於USB 1.1介面中的效能。本論文的架構分為硬體，韌體，軟體三大部分，硬體即使用EZ-USB，韌體使用Keil C 編譯器來撰寫，軟體部分則使用Microsoft Visual C++ 6.0來開發視窗介面的程式。

The thesis is chiefly on utilizing the chip USB Version1.1, EZ-USB FX, which is manufactured by Cypress Semiconductor Corporation. This chip possesses an enhanced 8051 microprocessor. Its firmware can directly download by USB and use Renumeration TM technology to enumerate automatically. It has improved the convenience on development. The purpose of the thesis is to capitalize on the popularization of USB and the utility of HID (Human Interface Device), to capture and process the Analog-to-digital signal and Digital-to-analog signal by means of HID (Human Interface Device) within the utilization of USB 1.1 interface. The device has supported users to capture signals without the help of drivers and the necessity of electricity. The structure of the thesis is divided into 3 parts: Hardware, firmware, and software. EZ-USB is put to use as the hardware, the firmware is edited by Keil C Complier and the software is primarily compiled by Microsoft Visual C++ 6.0 to develop the program of windows interface.
