A bit later than anticipated, I have created initial releases for the dpfp project, a driver for DigitalPersona and Microsoft USB fingerprint readers.
My last attempt at the driver/library thing failed – I learned more about the device, and decided I should take a few steps back and work with a different design.
So far, the rewrite is working out, so I’m releasing an early version for people to try. The driver provides a simple character device interface, and the library provides a nice API to that interface. libdpfp includes an example program which you can use to scan your fingerprint to a PGM file.
This isn’t for general usage yet. There are basic instructions in the README file in the dpfp-driver distribution.
If you have questions, please don’t ask them in comments on my weblog, use the mailing list instead. Enjoy!
