Click library

  • Author : Stefan Ilic
  • Date : Nov 2023.
  • Type : ADC type

Software Support

We provide a library for the Current Sens 2 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 Sens 2 Click driver.

Standard 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 );

Example key functions :

  • 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 );

Example Description

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

The demo application is composed of two sections :

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 );
    }
}

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.CurrentSens2

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.
