摘要
Linux嵌入式技术下的设备驱动程序将操作系统与硬件联系起来,使得操作系统能够管理硬件设备,向应用程序提供访问硬件的调用。尽管硬件设备之间的差别很大,但是驱动程序的开发的自由度却很小,需要严格遵循一些规范,并有比较严格的性能要求。本文提出了Linux嵌入式技术下指纹采集系统设备驱动程序设计方案,结果表明系统运行良好,采集指纹速度快,图像清晰。
Under the Linux embedded technology＇s device driver to gather the operating system together with the hardware, will enable the operating system to be able to manage the hardware equipment, will provide to the application procedure visits hardware＇s transfer. Although there are big differences between the hardware equipments, but driver＇s development＇s degree-of-freedom is very actually small, needs to follow some standards strictly, and has the quite strict performance requirement. This article proposed under the Linux embedded technology the fingerprint gathering system device driver design proposal, indicated finally the systems operation is good, the gathering fingerprint speed is quick, the image is clear.
