Python library for ZFM-20 fingerprint sensor

The PyFingerprint library allows to use the ZhianTec ZFM-20 fingerprint sensor on the Raspberry Pi or other Linux machines.

Note: The library is inspired by the C++ library from Adafruit Industries:
https://github.com/adafruit/Adafruit-Fingerprint-Sensor-Library

Package building

Note: This should work properly on Debian 7 (Wheezy) and Debian 8 (Jessie).

First install the packages for building:

~$ sudo apt-get install devscripts

Than clone this repository:

~$ git clone https://github.com/bastianraschke/pyfingerprint.git

Build the package:

~$ cd ./pyfingerprint/src/
~$ debuild

Installation

Install the built Debian package:

~$ sudo dpkg -i ../python-fingerprint*.deb

Install missing dependencies:

~$ sudo apt-get -f install

Allow non-root user "pi" (replace it correctly) to use the serial port devices:

~$ sudo usermod -a -G dialout pi
~$ sudo reboot
