Library Description
The library covers all the necessary functions to control NFC 2 Click board. A library performs the communication with the device via I2C interface.
Key functions:
void nfc2_generic_write ( uint8_t *p_tx_data, uint8_t n_bytes )
- Generic write function.void nfc2_generic_read ( uint8_t *p_rx_h_data, uint8_t *p_rx_p_data )
- Generic read function.void nfc2_cmd_core_reset ( void )
- Core reset command function.Examples description
The application is composed of three sections :
void application_task ( )
{
while ( nfc2_check_irq( ) == NFC2_IQR_STATE_HIGH )
{
nfc2_read_ctrl_packet_data( &ctrl_pck_data );
Delay_ms( 100 );
nfc2_activate_rmt_mifare_card( );
Delay_ms( 100 );
nfc2_read_ctrl_packet_data( &ctrl_pck_data );
Delay_ms( 10 );
while ( nfc2_check_irq( ) == NFC2_IQR_STATE_LOW );
nfc2_read_ctrl_packet_data( &ctrl_pck_data );
nfc2_cmd_authenticate_sector( 0x30 );
Delay_ms( 100 );
nfc2_read_ctrl_packet_data( &ctrl_pck_data );
Delay_ms( 10 );
while ( nfc2_check_irq( ) == NFC2_IQR_STATE_LOW );
nfc2_read_ctrl_packet_data( &ctrl_pck_data );
display_nfc_data( );
mikrobus_logWrite( " Disconnect Card ", _LOG_LINE );
nfc2_cmd_card_disconnected( );
Delay_ms( 10 );
nfc2_read_ctrl_packet_data( &ctrl_pck_data );
Delay_ms( 10 );
while ( nfc2_check_irq( ) == NFC2_IQR_STATE_LOW );
nfc2_read_ctrl_packet_data( &ctrl_pck_data );
Delay_ms( 100 );
}
while ( nfc2_check_irq( ) == NFC2_IQR_STATE_LOW );
mikrobus_logWrite( "-----------------------", _LOG_LINE );
Delay_ms( 1000 );
}

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.
