Detailed Description

Fingerprint 5 Click Example.

Description

This example demonstrates how to use the Fingerprint 5 Click board to enroll and identify fingerprints. The application cycles through several states: checking firmware readiness, reading version info, deleting existing templates, enrolling new fingerprints, and continuously identifying them.

The demo application is composed of two sections :

Application Init

Initializes the logger and the Click board, resets the device and sets up the application state machine.

Application Task

Handles command processing and application state transitions, enabling fingerprint enrollment and identification.

Note: Make sure to place your finger on the sensor when prompted during enrollment and identification. The example registers 2 fingerprints by default.
