摘要
给出了基于USB2.0总线的数据采集系统,包括硬件设计、固件设计、驱动程序设计和应用程序设计等。该系统可以实现8路模拟信号的同步采样和16路开关量输入、输出。USB接口控制芯片采用Cypress公司FX2系列中的CY7C68013,通过对其可编程控制接口的设计实现了数据的高速连续采样和传输。
A data acquisition system based on USB2.0 is this paper, including the designing of hardware, firmware, drivers and application programs is presended. This system can realize analog signal sampling in 8 channels simuhaneously and the input and output of switching signal in 16 binary channels. The USB interface control chip adopted is CY7C68013, a product of the Company of Cypress. Through designing the control logic of its GPIF interface, sampling and transmiting with high speed have been realized.
