BIG 7-SEG Click

BIG 7-SEG 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.

Click Library

• Author : MikroE Team
• Date : Dec 2019.
• Type : SPI type

Software Support

Example Description

This application sets seven-segment leds on the display.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Big7Seg

Example Key Functions

• big7seg_cfg_setup Config Object Initialization function.

void big7seg_cfg_setup ( big7seg_cfg_t *cfg );

• big7seg_init Initialization function.

err_t big7seg_init ( big7seg_t *ctx, big7seg_cfg_t *cfg );

• big7seg_display_off Turn OFF BIG 7-SEG display.

void big7seg_display_off( big7seg_t *ctx );

• big7seg_write_data_number Function write number.

void big7seg_write_data_number( big7seg_t *ctx, uint8_t display_number );

• big7seg_write_data_character Function write character.

void big7seg_write_data_character( big7seg_t *ctx, char display_char );

Application Init

Driver initializaion and turning on the display by setting PWM pin to logic 1 and prepare to communcation via SPI.

void application_init ( void )
{
    log_cfg_t log_cfg;
    big7seg_cfg_t cfg;

    /** 
     * 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.

    big7seg_cfg_setup( &cfg );
    BIG7SEG_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    big7seg_init( &big7seg, &cfg );

    big7seg_set7seg( &big7seg );
    Delay_100ms( );
}

Application Task

This example shows functionality of the BIG 7-SEG R Click, shows number or character on display.

void application_task ( )
{
    uint8_t counter;

    big7seg_reset7seg( &big7seg );
    big7seg_display_on( &big7seg );
    Delay_1sec( );

    big7seg_write_data( &big7seg, 0x40 );
    Delay_1sec( );
    big7seg_write_data_character(  &big7seg, 'B' );
    Delay_1sec( );
    big7seg_write_data_character(  &big7seg, 'I' );
    Delay_1sec( );
    big7seg_write_data_character(  &big7seg, 'G' );
    Delay_1sec( );
    big7seg_write_data( &big7seg, 0x08 );
    Delay_1sec( );
    big7seg_write_data_number( &big7seg, 7 );
    Delay_1sec( );
    big7seg_write_data( &big7seg, 0x40 );
    Delay_1sec( );
    big7seg_write_data_character(  &big7seg, 'S' );
    Delay_1sec( );
    big7seg_write_data_character(  &big7seg, 'E' );
    Delay_1sec( );
    big7seg_write_data_character(  &big7seg, 'G' );
    Delay_1sec( );
    
    big7seg_write_data( &big7seg, 0x00 );
    Delay_1sec( );
    for ( counter = 65; counter < 91; counter ++ )
    {
        big7seg_write_data_character(  &big7seg, counter );
        Delay_1sec( );
    }

    big7seg_display_off( &big7seg );
    Delay_1sec( );
}

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.
