Click library

  • Author : Stefan Filipovic
  • Date : Feb 2022.
  • Type : I2C type

Software Support

We provide a library for the NTAG 5 Link 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.

Library Description

This library contains API for NTAG 5 Link Click driver.

Standard key functions :

Example key functions :

  • ntag5link_write_ndef_uri_record This function writes specific NDEF URI record to the memory address specified with NTAG5LINK_NDEF_MESSAGE_START_ADDRESS macro.
    err_t ntag5link_write_ndef_uri_record ( ntag5link_t *ctx, uint8_t uri_prefix, uint8_t *uri_data, uint8_t data_len );
  • ntag5link_write_message_to_memory This function writes specified number of data bytes to the user memory starting from block_addr.
    err_t ntag5link_write_message_to_memory ( ntag5link_t *ctx, uint16_t block_addr, uint8_t *message, uint16_t message_len );
  • ntag5link_read_message_from_memory This function reads specified number of data bytes from the user memory starting from block_addr.
    err_t ntag5link_read_message_from_memory ( ntag5link_t *ctx, uint16_t block_addr, uint8_t *message, uint16_t message_len );

Example Description

This example demonstrates the use of NTAG 5 Link click board by programming the specified NDEF URI record to the memory, and showing the memory read/write feature.

The demo application is composed of two sections :

Application Init

Initializes the driver and logger and performs the click default configuration which

enables the device and formats its user memory. After that it programs the specified NDEF URI record to the memory.

void application_init ( void )
{
log_cfg_t log_cfg;
ntag5link_cfg_t ntag5link_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
ntag5link_cfg_setup( &ntag5link_cfg );
NTAG5LINK_MAP_MIKROBUS( ntag5link_cfg, MIKROBUS_1 );
if ( I2C_MASTER_ERROR == ntag5link_init( &ntag5link, &ntag5link_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( NTAG5LINK_ERROR == ntag5link_default_cfg ( &ntag5link ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
URI_DATA, strlen ( URI_DATA ) ) )
{
log_printf( &logger, " NDEF URI record \"https://%s\" has been written\r\n", ( char * ) URI_DATA );
}
log_info( &logger, " Application Task " );
}

Application Task

Writes a desired number of data bytes to the memory and verifies that it is written

correctly by reading from the same memory location and displaying the memory content on the USB UART approximately every 5 seconds.

void application_task ( void )
{
uint8_t message_buf[ 100 ] = { 0 };
strlen ( TEXT_MESSAGE ) ) )
{
log_printf( &logger, " \"%s\" has been written to memory address 0x%.4X \r\n",
( char * ) TEXT_MESSAGE, ( uint16_t ) TEXT_MESSAGE_ADDRESS );
}
message_buf,
strlen ( TEXT_MESSAGE ) ) )
{
log_printf( &logger, " \"%s\" has been read from memory address 0x%.4X \r\n\n",
message_buf, ( uint16_t ) TEXT_MESSAGE_ADDRESS );
}
Delay_ms ( 5000 );
}

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.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.NTAG5Link

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.
