Detailed Description

Fingerprint2 Click example.

Description

This example demonstrates the use of Fingerprint 2 click board.

The demo application is composed of two sections :

Application Init

Initializes the driver, enables the click board, and then executes a command for registering a fingerprint.

Application Task

Compares a fingerprint on input to the registered fingerprint and displays the results on the USB UART every 5 seconds.

Additional Functions

fingerprint2_process ( ) - The general process of collecting data the module sends.
fp_reg_one ( uint8_t fngr_number ) - Registers a fingerprint at a specific index number.
fp_clr_one ( uint8_t fngr_number ) - Deletes a fingerprint from a specific index number.
fp_clr_all ( ) - Clears all fingerprints.
fp_curr_state ( ) - Lists the registration status and returns the number of registered fingerprints.
fp_compare ( ) - Compares a fingerprint on input to all other fingerprints that are memorized.

Note: In the registration state each fingerprint needs to be enrolled 3 times.

Logger initialization. Default baud rate: 115200 Default log level: LOG_LEVEL_DEBUG

Note: If USB_UART_RX and USB_UART_TX are defined as HAL_PIN_NC, you will need to define them manually for log to work. See LOG_MAP_USB_UART macro definition for detailed explanation.
