Click library

  • Author : MikroE Team
  • 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_get_response Magic RFID get response function.

    err_t magicrfid_get_response ( magicrfid_t *ctx, magicrfid_response_t *rsp );
  • magicrfid_parse_tag_rssi This function parses RSSI value of the tag.

    int8_t magicrfid_parse_tag_rssi ( magicrfid_response_t rsp );
  • magicrfid_parse_tag_epc This function parses EPC bytes of the tag.

    void magicrfid_parse_tag_epc ( magicrfid_response_t rsp, magicrfid_epc_t *epc );

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 ( ; ; );
    }
    magicrfid_default_cfg ( &magicrfid );
    log_info( &logger, " Application Task " );
}

Application Task

Scans for RFID TAGs and displays on the USB UART the EPC bytes of the detected tag. It also parses and displays the RSSI as well as the frequency this tag was detected at.


void application_task ( void ) 
{
    magicrfid_response_t rsp = { 0 };
    if ( ( MAGICRFID_OK == magicrfid_get_response ( &magicrfid, &rsp ) ) && 
         ( MAGICRFID_OPCODE_READ_TAG_ID_MULTIPLE == rsp.opcode ) )
    {
        if ( 0 == rsp.data_len )
        {
            log_printf( &logger, "\r\n --- SCANNING ---\r\n" );
        }
        else
        {
            log_printf( &logger, "\r\n --- TAG DETECTED ---\r\n" );
            int8_t tag_rssi = 0;
            uint32_t tag_freq = 0;
            magicrfid_epc_t epc = { 0 };
            tag_rssi = magicrfid_parse_tag_rssi ( rsp );
            log_printf( &logger, " RSSI: %d\r\n", ( int16_t ) tag_rssi );
            tag_freq = magicrfid_parse_tag_freq ( rsp );
            log_printf( &logger, " FREQ: %lu\r\n", tag_freq );
            magicrfid_parse_tag_epc ( rsp, &epc );
            log_printf( &logger, " EPC PC: 0x%.4X\r\n", epc.epc_pc );
            log_printf( &logger, " EPC ID (len: %u): ", ( uint16_t ) epc.data_len );
            for ( uint8_t cnt = 0; cnt < epc.data_len; cnt++ )
            {
                log_printf( &logger, "%.2X", ( uint16_t ) epc.data_buf[ cnt ] );
            }
            log_printf( &logger, "\r\n EPC CRC: 0x%.4X\r\n", epc.epc_crc );
            Delay_ms ( 100 );
            magicrfid_clear_buffers ( &magicrfid );
        }
    }
}

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.

PWM 2 click

5

PWM 2 click offers 48 independently controlled PWM channels, available over the onboard headers, perfectly suited for driving LEDs.

EERAM 2 Click

EERAM 2 Click is a standalone serial SRAM memory that includes shadow non-volatile backup. EERAM uses a small external capacitor to provide the energy needed to move the contents of the SRAM to the non-volatile cells when system power is lost.

ROTARY R Click

0

Rotary Click carries a 15-pulse incremental rotary encoder with detents, surrounded by a ring of 16 red LEDs. It’s a perfect solution for adding a precision input knob to your design. The encoder outputs A and B signals (out of phase to each other); the knob also acts as a push-button which sends an interrupt to the target board MCU. The LED ring is controlled through SPI lines (CS, SCK, MISO, MOSI). Rotary Click can be used with either a 3.3V or 5V power supply.
