AlphaNum G 2 Click

AlphaNum G 2 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 demonstrates the use of the AlphaNum G 2 Click board™ by writing and displaying the desired alphanumeric characters.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.AlphaNumG2

Example Key Functions

• alphanumg2_cfg_setup Config Object Initialization function.

void alphanumg2_cfg_setup ( alphanumg2_cfg_t *cfg );

• alphanumg2_init Initialization function.

err_t alphanumg2_init ( alphanumg2_t *ctx, alphanumg2_cfg_t *cfg );

• alphanumg2_default_cfg Click Default Configuration function.

err_t alphanumg2_default_cfg ( alphanumg2_t *ctx );

• alphanumg2_display_character AlphaNum G 2 display character function.

err_t alphanumg2_display_character ( alphanumg2_t *ctx, uint8_t left_char, uint16_t left_brightness, uint8_t right_char, uint16_t right_brightness );

• alphanumg2_set_led_output AlphaNum G 2 set LED output function.

err_t alphanumg2_set_led_output ( alphanumg2_t *ctx, uint16_t seg_bit_mask, alphanumg2_dot_t seg_dot, uint16_t brightness );

Application Init

Initialization of SPI module and log UART. After driver initialization, the app executes a default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    alphanumg2_cfg_t alphanumg2_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.
    alphanumg2_cfg_setup( &alphanumg2_cfg );
    ALPHANUMG2_MAP_MIKROBUS( alphanumg2_cfg, MIKROBUS_1 );
    if ( SPI_MASTER_ERROR == alphanumg2_init( &alphanumg2, &alphanumg2_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( ALPHANUMG2_ERROR == alphanumg2_default_cfg ( &alphanumg2 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
    log_printf( &logger, "------------------------\r\n" );
    Delay_ms ( 100 );
}

Application Task

The demo application displays digits from '0' to '9', symbols: colon, semicolon, less-than, equals-to, greater-than, question mark, at sign and capital alphabet letters, on both alphanumeric segments of the Click. Results are being sent to the UART Terminal, where you can track their changes.

void application_task ( void )
{
    log_printf( &logger, " %c %c\r\n", character, character + 1 );
    if ( ALPHANUMG2_OK == alphanumg2_display_character( &alphanumg2, 
                                                        character, ALPHANUMG2_BRIGHTNESS_MAX, 
                                                        character + 1, ALPHANUMG2_BRIGHTNESS_MAX ) )
    {
        character++;
        if ( ASCII_CHARACTER_UPPERCASE_Z <= character )
        {
            character = ASCII_CHARACTER_DIGIT_0;
            log_printf( &logger, "------------------------\r\n" );
            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.
