Installation
Raspberry Pi
- Enable Serial Interface for Raspberry Pi (Not required in case of windows)
- Open a terminal and run the following commands to enable I2C and Serial：
sudo raspi-config
- Choose Interfacing Options -> Serial->
Set "would you like a login shell to be accessible over serial?" --> No
Set "would you like the serial port hardware to be enabled?" --> Yes
- Install required dependency by running the below command
sudo apt-get install python3-pil python3-pil.imagetk
- Connect usb fingerprint on raspberry Pi usb port.
- Now open terminal and run the below command to download/ clone usb fingerprint repository
git clone https://github.com/sbcshop/USB-Fingerprint.git
(It will clone the repository inside home/pi location.)
- Enter downloaded repository location by typing below command.
cd USB-Fingerprint
- Now start the GUI of USB fingerprint by running the below command.
python3 fingerprint_GUI.py
- Type COM port and Baud Rate as ( default is 9600) from above GUI ("/dev/ttyACM0" in case of default connection), and click on connect button to start communication with fingerprint sensor.
Note: In case of error while opening the COM port run the below command to check connected devices on USB port.(connect and remove to check it)
ls -l /dev/tty*
GUI Features
- Compare Fingerprint - Option to Compare registered Fingerprint.
- Add Fingerprint - Add New Fingerprint, will assign an ID for each successful registration.
- Remove Fingerprint ( By ID) - Remove registered Fingerprint for a specific ID.
- Remove All Fingerprint (Registered) - Remove all saved fingerprints in a single click.
