BARGRAPH 3 Click

BARGRAPH 3 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

Used to create various types of VU meters, status indicators, different types of counters and similar devices.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.BarGraph3

Example Key Functions

• bargraph3_cfg_setup Config Object Initialization function.

void bargraph3_cfg_setup ( bargraph3_cfg_t *cfg );

• bargraph3_init Initialization function.

err_t bargraph3_init ( bargraph3_t *ctx, bargraph3_cfg_t *cfg );

• bargraph3_display This function control the displey.

void bargraph3_display  ( bargraph3_t *ctx, uint8_t ctrl, uint8_t dir, uint8_t counter );

• bargraph3_set_pwm This function set PWM.

void bargraph3_set_pwm ( bargraph3_t *ctx, uint8_t state );

• bargraph3_enable Functions for enable the chip.

void bargraph3_enable ( bargraph3_t *ctx, uint8_t state );

Application Init

Initialization driver init, enable device and set PWM.

void application_init ( void )
{
 log_cfg_t log_cfg;
    bargraph3_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.

    bargraph3_cfg_setup( &cfg );
    BARGRAPH3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    bargraph3_init( &bargraph3, &cfg );
}

Application Task

Counter passes through the loop and logs the value of the counter on the bargraph display.

void application_task ( void )
{
    uint8_t bargraph_cnt;
    
    for (bargraph_cnt = 0; bargraph_cnt <= 5; bargraph_cnt++)
    {
        bargraph3_display(  &bargraph3, BARGRAPH3_INCREASE_LED,  BARGRAPH3_DIRECTION_BOTTOM_TO_TOP, bargraph_cnt);
        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.
