AlphaNum R Click

AlphaNum R 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.

Example Description

This example showcases the initialization and configuration of the logger and Click modules and shows how to display characters and numbers on both LED segments of the Click.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.AlphaNumR

Example Key Functions

• alphanumr_cfg_setup Config Object Initialization function.

void alphanumr_cfg_setup ( alphanumr_cfg_t *cfg );

• alphanumr_init Initialization function.

err_t alphanumr_init ( alphanumr_t *ctx, alphanumr_cfg_t *cfg );

• alphanumr_default_cfg Click Default Configuration function.

void alphanumr_default_cfg ( alphanumr_t *ctx );

• alphanumr_write_character This function displays characters on the left and right LED segments.

void alphanumr_write_character ( alphanumr_t *ctx, uint8_t left_char, uint8_t right_char );

• alphanumr_write_number This function displays numbers on the left and right LED segments.

void alphanumr_write_number ( alphanumr_t *ctx, uint8_t left_char, uint8_t right_char );

Application Init

This function initializes and configures the logger and Click modules.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    alphanumr_cfg_t alphanumr_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.

    alphanumr_cfg_setup( &alphanumr_cfg );
    ALPHANUMR_MAP_MIKROBUS( alphanumr_cfg, MIKROBUS_POSITION_ALPHANUMR );
    err_t init_flag  = alphanumr_init( &alphanumr, &alphanumr_cfg );
    if ( SPI_MASTER_ERROR == init_flag ) {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }

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

Application Task

This function sets the time interval at which the symbols are displayed on the LED segments and shows a few characters and numbers.

void application_task ( void ) 
{
    alphanumr_set_display_interval( &alphanumr, 1000 );

    alphanumr_write_character( &alphanumr, 'M', 'E' );
    alphanumr_write_character( &alphanumr, '@', '?' );

    alphanumr_write_number( &alphanumr, 0,  1 );
    alphanumr_write_number( &alphanumr, 1,  2 );
    alphanumr_write_number( &alphanumr, 2,  3 );
    alphanumr_write_number( &alphanumr, 3,  4 );
}

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.
