BarGraph Click

BarGraph 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 : jan 2020.
  • Type : SPI type

Software Support

Example Description

This application uses a high-quality bar graph LED display.

Example Libraries

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.BarGraph

Example Key Functions

  • bargraph_cfg_setup Config Object Initialization function.
void bargraph_cfg_setup ( bargraph_cfg_t *cfg );
  • bargraph_init Initialization function.
err_t bargraph_init ( bargraph_t *ctx, bargraph_cfg_t *cfg );
  • bargraph_generic_transfer Generic transfer function.
void bargraph_generic_transfer ( bargraph_t *ctx, spi_master_transfer_data_t *block );
  • bargraph_driver_init Functions for initializes the chip.
void bargraph_driver_init ( bargraph_t *ctx );
  • bargraph_reset Functions for reset the chip.
void bargraph_reset ( bargraph_t *ctx );
  • bargraph_display Displays function.
void bargraph_display ( bargraph_t *ctx, uint8_t input );

Application Init

Initializes driver init and BarGraph init.

void application_init ( void )
{
    log_cfg_t log_cfg;
    bargraph_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.

    bargraph_cfg_setup( &cfg );
    BARGRAPH_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    bargraph_init( &bargraph, &cfg );
}

Application Task

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

void application_task ( void )
{
    for ( cnt = 0; cnt <= 10; cnt++ )
    {
        bargraph_display( &bargraph, cnt );
        Delay_ms ( 500 );
    }
}

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.
