Design the fingerprint gathering system device driver under the Linux embedded technology
Zhao Haifeng · Computer Programming Skills & Maintenance · 2008
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 vis-its hardware's transfer. Although there are big differences between the hardware equipments, but driver's development's de-gree-of-freedom is very actually small, needs to follow some standards strictly, and has the quite strict performance require-ment. This article proposed under the Linux embedded technology the fingerprint gathering system device driver design pro-posal, indicated finally the systems operation is good, the gathering fingerprint speed is quick, the image is clear.
