Detailed Description

Fingerprint 3 Click example.

Description

This example reads and processes data from Fingerprint 3 clicks.

The demo application is composed of two sections :

Application Init

Initializes the driver, configures the sensor, and enrolls fingerprints.

Application Task

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.

Additional Function

static void display_error ( uint8_t *message )
static void display_full_rsp ( fingerprint3_t *ctx )
static void search_finger( fingerprint3_t *ctx )
static void match_finger( fingerprint3_t *ctx, uint16_t location )
static uint8_t enroll_finger( fingerprint3_t *ctx, uint16_t location, uint8_t features )

void application_init ( void )

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.
