Click library

  • Author : Stefan Filipovic
  • Date : Apr 2024.
  • Type : ADC/I2C type

Software Support

We provide a library for the Current 11 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for Current 11 Click driver.

Standard key functions :

  • current11_cfg_setup Config Object Initialization function.

    void current11_cfg_setup ( current11_cfg_t *cfg );
  • current11_init Initialization function.

    err_t current11_init ( current11_t *ctx, current11_cfg_t *cfg );

Example key functions :

  • current11_set_vref This function sets the voltage reference for Current 11 Click driver.

    err_t current11_set_vref ( current11_t *ctx, float vref );
  • current11_calibrate_offset This function calibrates the zero current offset value.

    err_t current11_calibrate_offset ( current11_t *ctx );
  • current11_read_current This function reads the input current level [A] based on CURRENT11_NUM_CONVERSIONS of voltage measurements.

    err_t current11_read_current ( current11_t *ctx, float *current );

Example Description

This example demonstrates the use of Current 11 Click board by reading and displaying the input current measurements.

The demo application is composed of two sections :

Application Init

Initializes the driver and calibrates the zero current offset.


void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    current11_cfg_t current11_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.
    current11_cfg_setup( &current11_cfg );
    CURRENT11_MAP_MIKROBUS( current11_cfg, MIKROBUS_1 );
    err_t init_flag = current11_init( &current11, &current11_cfg );
    if ( ( ADC_ERROR == init_flag ) || ( I2C_MASTER_ERROR == init_flag ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    log_printf( &logger, " Calibrating zero current offset in 5 seconds...\r\n" );
    log_printf( &logger, " Make sure no current flows through the sensor during the calibration process.\r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    if ( CURRENT11_ERROR == current11_calibrate_offset ( &current11 ) )
    {
        log_error( &logger, " Calibrate offset." );
        for ( ; ; );
    }
    log_printf( &logger, " Calibration DONE.\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 ( CURRENT11_OK == current11_read_current ( &current11, &current ) ) 
    {
        log_printf( &logger, " Current : %.1f A\r\n\n", current );
        Delay_ms ( 1000 );
    }
}

Note

For better accuracy, set the voltage reference by using the current11_set_vref function, increase the number of conversions by modifying the CURRENT11_NUM_CONVERSIONS macro, and adjust the CURRENT11_COUPLING_FACTOR_G_A value.

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Current11

Additional notes and informations

Depending on the development board you are using, you may need USB UART Click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all MikroElektronika compilers.
