Installation

Python

Required Hardware

Raspberry Pi x 1
Pi-Finger x 1

Enable I2C and Serial Interface

Open a terminal and run the following commands to enable I2C：

sudo raspi-config

Choose Interfacing Options -> I2C ->yes

Again run below command to enable Serial

sudo raspi-config

Choose Interfacing Options -> Serial -> No -> Yes

You can also enable Serial and I2C using Graphical method, Open Menu by clicking on Raspberry Pi icon >> Preferences >> Raspberry Pi Configurations >> Interfaces , and select below option.

Now reboot your pi by running the below command :

sudo reboot

Board Test

Connect PiFinger on top of 40 pins stackable GPIO header of Raspberry Pi.

Now Clone/Download PiFinger Repository by running below command or directly download from Github.

git clone https://github.com/sbcshop/PiFinger.git

Open cloned/downloaded folder and choose your environment type (i.e: Raspberry Pi or Windows)

For Raspberry Pi

Run PiFinger GUI by running the below command:

python3 PiFinger_GUI.py or using any python3 supported ide.

Select COM port and Baud Rate ( default is 9600) from the above GUI ("/dev/ttyS0" in case of default connection), and click on connect button to start communication with the fingerprint sensor.

For Windows

Run PiFinger GUI by running "PiFinger_GUI.py" file with any python3 supported ide.

Select COM port and Baud Rate ( default is 9600) from above GUI ("COM7" (check comport from device manager) in case of default connection), and click on connect button to start communication with the fingerprint sensor.

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.

-LED display explanation
+== Resources ==
-The LED light of the PiFinger shows the current working status.
-If the LED1 and the LED2 flash in turn, it means that the PiFinger is in operation mode. If the LED1 or the LED2 is blinking alone, it means that the PiFinger is in the demo mode.
+''' Github '''
-The PiFinger will be in the demo mode after powered on or reset. Send any command to it will make it leave demo mode and enter operation mode immediately, and it will process the received command. When the PiFinger is in operation mode, only power on or reset it can make it back to demo mode.
