Fingerprint 3 Click is an adapter Click boardâ„¢, used to interface a compatible Fingerprint Sensor with Two-Color LED Ring with the host MCU.
We provide a library for the Fingerprint3 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
Package can be downloaded/installed directly form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.
This library contains API for Fingerprint3 Click driver.
void fingerprint3_cfg_setup ( fingerprint3_cfg_t *cfg );
FINGERPRINT3_RETVAL fingerprint3_init ( fingerprint3_t *ctx, fingerprint3_cfg_t *cfg );
uint8_t fingerprint3_set_config ( fingerprint3_t *ctx, uint32_t addr, uint32_t pass );
uint8_t fingerprint3_take_image ( fingerprint3_t *ctx );
uint8_t fingerprint3_aura_control ( fingerprint3_t *ctx, uint8_t control, uint8_t speed, uint8_t color, uint8_t times );
uint8_t fingerprint3_finger_indicator ( fingerprint3_t *ctx );
This example reads and processes data from Fingerprint 3 clicks.
The demo application is composed of two sections :
Initializes the driver, configures the sensor, and enrolls fingerprints.
Takes an image of the finger, then checks if there's a fingerprint in the library that matches the one it has just read. All data is being logged on the USB UART.
The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Additional notes and informations
Depending on the development board you are using, you may need USB UART click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
