Abstract
USB(Universal Serial Bus) is very convenient for high speed data acquisition,we can complete more efficient,more economical and faster data acquisition using USB interface than in traditional ways.In this paper we discuss the software and hardware design of a high speed data acquisition system based on USB 2.0.At first the system hardware design part is introduced,including the hardware design project and the CY7C68013 chip adopted by the system.The software part mainly consists of three parts of firmware design,driver program design and application program design,and the emphasis is put on the designing of the USB driver program under Windows 2000.
