UNIQUE ID Click

UNIQUE ID Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

• Type : One Wire type

Software Support

Example Description

This example demonstrates the use of UNIQUE ID Click board by reading and displaying Family Code and Serial Number on the UART Terminal.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.UNIQUEID

Example Key Functions

• uniqueid_cfg_setup Config Object Initialization function.

void uniqueid_cfg_setup ( uniqueid_cfg_t *cfg );

• uniqueid_init Initialization function.

err_t uniqueid_init ( uniqueid_t *ctx, uniqueid_cfg_t *cfg );

• uniqueid_read_id This function reads Family Code and Serial Number of device's ROM memory.

err_t uniqueid_read_id ( uniqueid_t *ctx, uint8_t *family, uint8_t *serial_num ); 

Application Init

Initionalizes both logger config object and Click config object.

void application_init ( void )
{
	log_cfg_t log_cfg;  /**< Logger config object. */
    uniqueid_cfg_t uniqueid_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
    uniqueid_cfg_setup( &uniqueid_cfg );
    UNIQUEID_MAP_MIKROBUS( uniqueid_cfg, MIKROBUS_1 );
    if ( ONE_WIRE_ERROR == uniqueid_init( &uniqueid, &uniqueid_cfg ) ) 
    {
        log_error( &logger, " Initialization error." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

Demonstrates the usage of uniqueid_read_id function, which stores the Family Code and Serial Number of the Click in family_code and serial_num variables. Both values will be displayed on the UART Terminal.

void application_task ( void )
{
	uint8_t family_code;
    uint8_t serial_num[ 6 ];
    
    if ( UNIQUEID_OK == uniqueid_read_id( &uniqueid, &family_code, &serial_num[ 0 ] ) )
    {
        log_printf( &logger, "Family Code = 0x%.2X\r\n", ( uint16_t ) family_code ); 
        log_printf( &logger, "Serial Number = 0x%.2X%.2X%.2X%.2X%.2X%.2X\r\n", 
                    ( uint16_t ) serial_num[ 0 ], ( uint16_t ) serial_num[ 1 ], 
                    ( uint16_t ) serial_num[ 2 ], ( uint16_t ) serial_num[ 3 ], 
                    ( uint16_t ) serial_num[ 4 ], ( uint16_t ) serial_num[ 5 ] ); 
    }      
    
    Delay_ms ( 1000 ); 
}

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
