Click library

  • Author : Stefan Filipovic
  • Date : Mar 2024.
  • Type : UART type

Software Support

We provide a library for the Barcode 3 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 Barcode 3 Click driver.

Standard key functions :

  • barcode3_cfg_setup Config Object Initialization function.

    void barcode3_cfg_setup ( barcode3_cfg_t *cfg );
  • barcode3_init Initialization function.

    err_t barcode3_init ( barcode3_t *ctx, barcode3_cfg_t *cfg );

Example key functions :

  • barcode3_generic_read This function reads a desired number of data bytes by using UART serial interface.

    err_t barcode3_generic_read ( barcode3_t *ctx, uint8_t *data_out, uint16_t len );
  • barcode3_start_scanning This function starts the barcode scanning by setting the TRG pin to low logic state.

    void barcode3_start_scanning ( barcode3_t *ctx );
  • barcode3_stop_scanning This function stops the barcode scanning by setting the TRG pin to high logic state.

    void barcode3_stop_scanning ( barcode3_t *ctx );

Example Description

This example demonstrates the use of the Barcode 3 Click board by scanning and displaying the content of a barcode or QR Code.

The demo application is composed of two sections :

Application Init

Initializes the driver, stops scanning and resets the barcode device.


void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    barcode3_cfg_t barcode3_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.
    barcode3_cfg_setup( &barcode3_cfg );
    BARCODE3_MAP_MIKROBUS( barcode3_cfg, MIKROBUS_1 );
    if ( UART_ERROR == barcode3_init( &barcode3, &barcode3_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    barcode3_stop_scanning ( &barcode3 );
    barcode3_reset_device ( &barcode3 );
    log_info( &logger, " Application Task " );
}

Application Task

Triggers scanning and waits up to 3 seconds for the barcode to be detected. If a barcode or QR Code is detected, it displays its content on the USB UART.

void application_task ( void )
{
    uint16_t timeout = 0;
    log_printf( &logger, "\r\n------- SCAN START ------\r\n" );
    barcode3_start_scanning ( &barcode3 );
    while ( ++timeout < 3000 )
    {
        if ( BARCODE3_OK == barcode3_process( &barcode3 ) )
        {
            barcode3_log_app_buf( );
            barcode3_clear_app_buf( );
            Delay_10ms ( );
            while ( BARCODE3_OK == barcode3_process( &barcode3 ) )
            {
                barcode3_log_app_buf( );
                barcode3_clear_app_buf( );
                Delay_10ms ( );
            }
            break;
        }
        Delay_1ms ( );
    }
    log_printf( &logger, "------- SCAN STOP -------\r\n" );
    barcode3_stop_scanning ( &barcode3 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}

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.Barcode3

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.
