Bargraph 2 Click

Bargraph 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.

• Type : SPI type

Software Support

Example Description

The example starts off with the initalisation and configuration of the logger and Click modules and later on showcases different ways of lighting LED diodes on the Click.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Bargraph2

Example Key Functions

• bargraph2_cfg_setup Config Object Initialization function.

void bargraph2_cfg_setup ( bargraph2_cfg_t *cfg );

• bargraph2_init Initialization function.

err_t bargraph2_init ( bargraph2_t *ctx, bargraph2_cfg_t *cfg );

• bargraph2_led_green This function turns on the green LED diode of the chosen segment.

void bargraph2_led_green ( bargraph2_t *ctx, uint8_t index );

• bargraph2_leds_green This function turns on green LED diodes from the starting index to the end index.

void bargraph2_leds_green ( bargraph2_t *ctx, int start_index, int end_index );

• bargraph2_lights_out This function turns off all the LED diodes.

void bargraph2_lights_out ( bargraph2_t *ctx );

Application Init

This function initializes and configures the logger and Click modules.

void application_init ( )
{
    log_cfg_t log_cfg;
    bargraph2_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.

    bargraph2_cfg_setup( &cfg );
    BARGRAPH2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    bargraph2_init( &bargraph2, &cfg );
}

Application Task

This function shows the user how to light single and multiple LED diodes.

void application_task ( )
{
    uint8_t cnt; 
        
    // Single LED switch
    
    for ( cnt = 1; cnt <= 10 ; cnt++ )
    {
        bargraph2_led_green( &bargraph2, cnt );
        Delay_ms ( 200 );
        bargraph2_led_red( &bargraph2, 10 - ( cnt - 1 ) );
        Delay_ms ( 200 );
    }
    
    bargraph2_lights_out ( &bargraph2 );

    // Multiple LED switch

    bargraph2_leds_green ( &bargraph2, 1, 10 );
    Delay_ms ( 1000 );
    bargraph2_leds_red ( &bargraph2, 1, 10 );
    Delay_ms ( 1000 );
    bargraph2_leds_yellow ( &bargraph2, 1, 10 );
    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.
