NFC 2 Click is a compact add-on board that contains a highly integrated NFC transceiver for contactless communication. This board features the PN7150, the best plug&play high-performance full NFC solution with integrated firmware and NCI interface designed for contactless communication at 13.56 MHz from NXP USA Inc.
We provide a library for the NFC2 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 from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.
This library contains API for NFC2 Click driver.
nfc2_cfg_setup
Config Object Initialization function.
void nfc2_cfg_setup ( nfc2_cfg_t *cfg );
nfc2_init
Initialization function.
err_t nfc2_init ( nfc2_t *ctx, nfc2_cfg_t *cfg );
nfc2_default_cfg
Click Default Configuration function.
err_t nfc2_default_cfg ( nfc2_t *ctx );
nfc2_hw_reset
HW reset function.
void nfc2_hw_reset( nfc2_t *ctx );
nfc2_core_set_protocol_config
Set protocol configuration function.
void nfc2_core_set_protocol_config ( nfc2_t *ctx );
nfc2_cmd_card_disconnected
Card disconnected command function.
void nfc2_cmd_card_disconnected ( nfc2_t *ctx );
This is an example which demonstrates the usage of NFC 2 Click board.
The demo application is composed of two sections :
Initialization driver enables - I2C, hw reset, reseteting and initialize core, disabling standby mode, starting test procedure, set configuration and start discovery, also write log.
void application_init ( void ) {
log_cfg_t log_cfg; /**< Logger config object. */
nfc2_cfg_t nfc2_cfg; /**< Click config object. */
/**
* 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 @b LOG_MAP_USB_UART macro definition for detailed explanation.

NFC 2 Click board can be used for detection of RFiD tag and displays it's value via USART terminal. All data logs write on USB uart changes for every 1 sec.
void application_task ( void ) {
while ( nfc2_check_irq( &nfc2 ) == NFC2_IRQ_STATE_HIGH ) {
nfc2_read_nfc_data ( &nfc2, &ctrl_pck_data );
}
while ( nfc2_check_irq( &nfc2 ) == NFC2_IRQ_STATE_LOW );
log_printf( &logger, "-----------------------\r\n" );
Delay_ms ( 1000 );
}
The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

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. UART terminal is available in all MikroElektronika compilers.
