摘　　要：文章主要介绍了利用FPS200指纹芯片设计指纹检测模块,该指纹检测模块可以通过USB、SPI或并行接口与相应的主机相连,重点介绍了该模块利用USB接口与计算机相连,并且利用相应的软件控制该指纹检测模块采集指纹图像,最后介绍了在使用USB接口时,该模块驱动程序编写方法、设备初始化方法和指纹图像的读取方法。经实验证明,通过该指纹检测模块性能稳定,可以采集高质量的指纹图像。This paper is to discuss a FPS200- fingerprint- chip based fingerprint detection module which can be connected with the corresponding host via USB, SPI or microprocessor bus interface. The main part of the paper introduces how to connect the module with computer through USB interface and how to collect fingerprint image under the control of the fingerprint detection module with appropriate software. The paper ends with an introduction of the method(s) for the programming of the driver program, device initialization and reading of the fingerprint image when using USB interface. Experiments have proved that this fingerprint detection module steady module performance and can be used to collect high quality fingerprint image.
