Magic RFID click

Magic RFID Click is a compact add-on board that contains an embedded RFID module. This board features the M6E-NANO, UHF RFID module with ultra-low power consumption from JADAK. Supporting the EPC Gen2V2 and ISO 18000-63 standard, the M6E-NANO module is available for global use. It operates in the Ultra High Frequency (UHF) band in a range from 859 up to 930MHz and can be used for write/read applications.

Click library

  • Author : Stefan Ilic
  • Date : Sep 2021.
  • Type : UART type

Software Support

We provide a library for the MagicRFID 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 MagicRFID Click driver.

Standard key functions :

  • magicrfid_cfg_setup Config Object Initialization function.
void magicrfid_cfg_setup ( magicrfid_cfg_t *cfg );
  • magicrfid_init Initialization function.
err_t magicrfid_init ( magicrfid_t *ctx, magicrfid_cfg_t *cfg );
  • magicrfid_default_cfg Click Default Configuration function.
void magicrfid_default_cfg ( magicrfid_t *ctx );

Example key functions :

  • magicrfid_device_reset Magic RFID device reset function.
void magicrfid_device_reset ( magicrfid_t *ctx );
  • magicrfid_send_command Magic RFID send command function.
void magicrfid_send_command ( magicrfid_t *ctx, uint8_t *tx_buf, uint8_t len );
  • magicrfid_get_tag_rssi Get Tag RSSI value.
int8_t magicrfid_get_tag_rssi ( magicrfid_data_t *data_obj );

Example Description

This example reads and processes data from Magic RFID clicks.

The demo application is composed of two sections :

Application Init

Initialize driver init and starts default configuration module.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    magicrfid_cfg_t magicrfid_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.
     */
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );

    // Click initialization.
    magicrfid_cfg_setup( &magicrfid_cfg );
    MAGICRFID_MAP_MIKROBUS( magicrfid_cfg, MIKROBUS_1 );
    if ( UART_ERROR == magicrfid_init( &magicrfid, &magicrfid_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    log_printf( &logger, " >> Please, wait for device setup. \r\n" );
    magicrfid_default_cfg ( &magicrfid );
    Delay_ms( 1000 );
    log_printf( &logger, " >> Initialization done, reading tag is available. \r\n" );
    log_info( &logger, " Application Task " );
}

Application Task

Reads TAG information and RSSI value of the TAG and logs it on UART.

void application_task ( void ) 
{
    magicrfid_process( &magicrfid, &tag );
    if ( magicrfid_get_data_status( &tag ) == 1 ) 
    {
        magicrfid_tag_parser( &tag );

        log_printf( &logger, " >> TAG INFO: 0x" );
        for( uint8_t cnt = 0; cnt < 12; cnt++ ) 
        {
            log_printf( &logger, "%.2X", ( uint16_t ) tag.tag_buf[ cnt ] );
        }
        log_printf( &logger, "\r\n" );
        log_printf( &logger, " >> TAG RSSI: %d\r\n", ( uint16_t ) tag.tag_rssi );
        magicrfid_reset_data( &tag );
    }
}

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.MagicRFID

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.
