Current Sens 2 Click

Current Sens 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.

Example Description

This example demonstrates the use of Current Sens 2 Click board by reading and displaying the input current measurements.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.CurrentSens2

Example Key Functions

• currentsens2_cfg_setup Config Object Initialization function.

void currentsens2_cfg_setup ( currentsens2_cfg_t *cfg );

• currentsens2_init Initialization function.

err_t currentsens2_init ( currentsens2_t *ctx, currentsens2_cfg_t *cfg );

• currentsens2_get_int_pin Current Sens 2 get int pin state function.

uint8_t currentsens2_get_int_pin ( currentsens2_t *ctx );

• currentsens2_tare Current Sens 2 tare function.

err_t currentsens2_tare ( currentsens2_t *ctx );

• currentsens2_get_current Current Sens 2 read current function.

err_t currentsens2_get_current ( currentsens2_t *ctx, float *current );

Application Init

Initializes the driver and logger.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    currentsens2_cfg_t currentsens2_cfg;  /**< Click config object. */

    /** 
     * 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.
    currentsens2_cfg_setup( &currentsens2_cfg );
    CURRENTSENS2_MAP_MIKROBUS( currentsens2_cfg, MIKROBUS_1 );
    if ( ADC_ERROR == currentsens2_init( &currentsens2, &currentsens2_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    log_printf( &logger, " Remove Click from the electrical circuit \r\n" );
    Delay_ms ( 1000 );
    if ( CURRENTSENS2_ERROR == currentsens2_tare ( &currentsens2 ) )
    {
        log_error( &logger, " Click tare error." );
        for ( ; ; );
    }

    currentsens2_set_prim_turn_no( &currentsens2, CURRENTSENS2_NUM_OF_PASSES_1 );

    log_printf( &logger, " Connect Click to the electrical circuit \r\n" );
    log_info( &logger, " Application Task " );
}

Application Task

Reads the input current measurements and displays the results on the USB UART approximately once per second.

void application_task ( void ) 
{
    float current = 0;
    if ( CURRENTSENS2_OK == currentsens2_get_current ( &currentsens2, &current ) ) 
    {
        log_printf( &logger, " Current : %.2f[A]\r\n\n", current );
        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.
