NFC Extend Click is NFC tag interface device with possibility of using any shape and size external antenna, offering 16 Kbit of electrically erasable programmable memory (EEPROM). This Click Boardâ„¢ offer two communication interfaces.>
We provide a library for the NfcExtend 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 NfcExtend Click driver.
void nfcextend_cfg_setup ( nfcextend_cfg_t *cfg );
NFCEXTEND_RETVAL nfcextend_init ( nfcextend_t *ctx, nfcextend_cfg_t *cfg );
void nfcextend_default_cfg ( nfcextend_t *ctx );
uint8_t nfcextend_i2c_set ( nfcextend_t *ctx, nfcextend_block_t *block );
uint8_t nfcextend_i2c_get ( nfcextend_t *ctx, nfcextend_block_t *block );
uint8_t nfcextend_digital_read_int ( nfcextend_t *ctx );
This example showcases how to configure and use the NFC Extend Click. The Click is an NFC tag
interface which uses the I2C serial interface and an RF link interface in order to communicate. The example requires the ST25 NFC Tap application which can be downloaded to your phone.
The demo application is composed of two sections :
This function initializes and configures the logger and Click modules.
This function waits for the interrupt signal, after which it expects data transfers. Once
some data has been detected it will open a communication channel with the device transmitting it and show the received data in the UART console.
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.
