RFID Breakout

USB Fingerprint board is a board comprise of an onboard Nuvoton MCU with an on-chip crypto-accelerator, Cortex-M23 TrustZone, and XOM facilities in a USB form-factor. A user can use the USB Fingerprint board with a PC or micro-controller with the Baud rate of 9600 bps or USB 2.0 full speed over the serial UART interface.

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) cmd: ls -l /dev/tty*
