7seg Click

7seg 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 : Mihajlo Djordjevic
  • Date : Dec 2019.
  • Type : SPI type

Software Support

Example Description

Example code consist of two sections: AppInit and AppTask, and shows number or character on 7seg display.

Example Libraries

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.7seg

Example Key Functions

  • c7seg_cfg_setup Config Object Initialization function.
void c7seg_cfg_setup ( c7seg_cfg_t *cfg );
  • c7seg_init Initialization function.
err_t c7seg_init ( c7seg_t *ctx, c7seg_cfg_t *cfg );
  • c7seg_default_cfg Click Default Configuration function.
void c7seg_default_cfg ( c7seg_t *ctx );
  • c7seg_display_mode This function sets display state for 7seg Click.
void c7seg_display_mode ( c7seg_t *ctx, uint8_t display_mode );
  • c7seg_write_data_number This function writes left and right number on 7seg display.
void c7seg_write_data_number ( c7seg_t *ctx, uint8_t left_number, uint8_t right_number );
  • c7seg_write_data_character This function writes left and right character on 7seg display.
void c7seg_write_data_character ( c7seg_t *ctx, char left_char, char right_char );

Application Init

Application Init performs Logger and Click Initialization.

void application_init ( void )
{
    log_cfg_t log_cfg;
    c7seg_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_printf( &logger, "-- Application  Init --\r\n" );
    Delay_ms ( 1000 );

    //  Click initialization.

    c7seg_cfg_setup( &cfg );
    C7SEG_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    c7seg_init( &c7seg, &cfg );
    
    c7seg_default_cfg ( &c7seg );
    Delay_ms ( 1000 );
}

Application Task

Application Task shows functionality of the 7seg Click, shows number or character on left and right display.

void application_task ( void )
{
    uint8_t counter;

    c7seg_display_mode( &c7seg, C7SEG_DISPLAY_ON );
    Delay_ms ( 1000 );
    
    for ( counter = 0; counter < 9; counter ++ )
    {
        c7seg_write_data_number( &c7seg, counter, counter + 1 );
        Delay_ms ( 1000 );
    }
    Delay_ms ( 1000 );

    for ( counter = 65; counter < 90; counter ++ )
    {
        c7seg_write_data_character( &c7seg, counter, counter + 1 );
        Delay_ms ( 1000 );
    }
    Delay_ms ( 1000 );

    c7seg_display_mode( &c7seg, C7SEG_DISPLAY_OFF );
    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.
