UT-S 7-SEG B 2 Click

UT-S 7-SEG B 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 UT-S 7-SEG B 2 Click board by writing and displaying the desired numbers on the screen.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.UTS7SEGB2

Example Key Functions

• uts7segb2_cfg_setup Config Object Initialization function.

void uts7segb2_cfg_setup ( uts7segb2_cfg_t *cfg );

• uts7segb2_init Initialization function.

err_t uts7segb2_init ( uts7segb2_t *ctx, uts7segb2_cfg_t *cfg );

• uts7segb2_default_cfg Click Default Configuration function.

err_t uts7segb2_default_cfg ( uts7segb2_t *ctx );

• uts7segb2_display_number This function displays the desired number and brightness on the selected segments.

err_t uts7segb2_display_number ( uts7segb2_t *ctx, uts7segb2_number_cfg_t number );

• uts7segb2_display_character This function displays the desired characters and brightness on the selected segments.

err_t uts7segb2_display_character ( uts7segb2_t *ctx, uts7segb2_character_cfg_t ascii_char );

• uts7segb2_set_led_output This function sets the LED driver output.

err_t uts7segb2_set_led_output ( uts7segb2_t *ctx, uts7segb2_seg_sel_t seg_sel, 
                                 uint32_t seg_bit_mask, 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. */
    uts7segb2_cfg_t uts7segb2_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.
    uts7segb2_cfg_setup( &uts7segb2_cfg );
    UTS7SEGB2_MAP_MIKROBUS( uts7segb2_cfg, MIKROBUS_1 );
    if ( SPI_MASTER_ERROR == uts7segb2_init( &uts7segb2, &uts7segb2_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( UTS7SEGB2_ERROR == uts7segb2_default_cfg ( &uts7segb2 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    
    number.brightness_top = UTS7SEGB2_BRIGHTNESS_DEFAULT;
    number.brightness_bottom = UTS7SEGB2_BRIGHTNESS_DEFAULT;
    number.base = UTS7SEGB2_BASE_NUM_SYS_HEXADECIMAL;
    number.dot_bit_mask = UTS7SEGB2_TOP_SEG_NO_DOT | UTS7SEGB2_BOTTOM_SEG_NO_DOT;
    log_info( &logger, " Application Task " );
    Delay_ms ( 100 );
}

Application Task

The demo application draws numbers, in hexadecimal format, from 0h to FFFh on the top segment group and from FFFh to 0h on the bottom segment group. Results are being sent to the UART Terminal, where you can track their changes.

void application_task ( void )
{
    for ( uint16_t num_cnt = 0; num_cnt <= UTS7SEGB2_HEXADECIMAL_NUM_MAX; num_cnt++ )
    {
        number.num_top = num_cnt;
        number.num_bottom = UTS7SEGB2_HEXADECIMAL_NUM_MAX - num_cnt;
        if ( UTS7SEGB2_OK == uts7segb2_display_number( &uts7segb2, number ) )
        {
            log_printf( &logger, " %.3X\r\n", number.num_top );
            log_printf( &logger, " %.3X\r\n\n", number.num_bottom );
            Delay_ms ( 100 );
        }
    }
    log_printf( &logger, " --------------\r\n\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.
