Current 6 Click

Current 6 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 6 Click board by reading the input voltage and current measurements.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Current6

Example Key Functions

• current6_cfg_setup Config Object Initialization function.

void current6_cfg_setup ( current6_cfg_t *cfg );

• current6_init Initialization function.

err_t current6_init ( current6_t *ctx, current6_cfg_t *cfg );

• current6_default_cfg Click Default Configuration function.

err_t current6_default_cfg ( current6_t *ctx );

• current6_get_alert_pin This function returns the alert pin logic state.

uint8_t current6_get_alert_pin ( current6_t *ctx );

• current6_read_data This function reads the input voltage and current measurement values.

err_t current6_read_data ( current6_t *ctx, float *voltage, float *current );

• current6_get_status This function reads and clears the status register.

err_t current6_get_status ( current6_t *ctx, uint16_t *status );

Application Init

Initializes the driver and performs the Click default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    current6_cfg_t current6_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.
    current6_cfg_setup( &current6_cfg );
    CURRENT6_MAP_MIKROBUS( current6_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == current6_init( &current6, &current6_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( CURRENT6_ERROR == current6_default_cfg ( &current6 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

Waits for the FIFO data interrupt and then reads the measurements of the input voltage and current and displays the results on the USB UART approximately once per second.

void application_task ( void )
{
    if ( current6_get_alert_pin ( &current6 ) )
    {
        uint16_t status;
        if ( CURRENT6_OK == current6_get_status ( &current6, &status ) )
        {
            if ( status & CURRENT6_FIFO_CFG_DATA_OVERFLOW_MASK )
            {
                float voltage, current;
                if ( CURRENT6_OK == current6_read_data ( &current6, &voltage, &current ) )
                {
                    log_printf( &logger, " Voltage: %.3f V\r\n Current: %.3f A\r\n\n", voltage, current );
                }
            }
        }
    }
}

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.
