mCurrent Sens Click

mCurrent Sens 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 : Stefan Filipovic
• Date : Apr 2026.
• Type : SPI type

Software Support

Example Description

This example demonstrates the use of mCurrent Sens Click for measuring voltage, current, and temperature on two independent channels.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.mCurrentSens

Example Key Functions

• mcurrentsens_cfg_setup This function initializes Click configuration structure to initial values.

  void mcurrentsens_cfg_setup ( mcurrentsens_cfg_t *cfg );

• mcurrentsens_init This function initializes all necessary pins and peripherals used for this Click board.

  err_t mcurrentsens_init ( mcurrentsens_t *ctx, mcurrentsens_cfg_t *cfg );

• mcurrentsens_default_cfg This function executes a default configuration of mCurrent Sens Click board.

  err_t mcurrentsens_default_cfg ( mcurrentsens_t *ctx );

• mcurrentsens_fetch_calib This function reads calibration values from external EEPROM.

  err_t mcurrentsens_fetch_calib ( mcurrentsens_t *ctx );

• mcurrentsens_read_ch1_current This function reads channel 1 current measurement in mA.

  err_t mcurrentsens_read_ch1_current ( mcurrentsens_t *ctx, float *data_out );

• mcurrentsens_read_ch1_voltage This function reads channel 1 voltage measurement in mV.

  err_t mcurrentsens_read_ch1_voltage ( mcurrentsens_t *ctx, float *data_out );

Application Init

Initializes communication, configures the device, optionally performs calibration, and loads calibration data from EEPROM. ADC oversampling ratio is set for faster runtime measurements.

void application_init ( void )
{
    log_cfg_t log_cfg;  
    mcurrentsens_cfg_t mcurrentsens_cfg;  

    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );
 
    // Click initialization.
    mcurrentsens_cfg_setup( &mcurrentsens_cfg );
    MCURRENTSENS_MAP_MIKROBUS( mcurrentsens_cfg, MIKROBUS_POSITION_MCURRENTSENS );
    if ( SPI_MASTER_ERROR == mcurrentsens_init( &mcurrentsens, &mcurrentsens_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( MCURRENTSENS_ERROR == mcurrentsens_default_cfg ( &mcurrentsens ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
 
#if ENABLE_CALIBRATION
    if ( MCURRENTSENS_OK == mcurrentsens_calibrate_device ( &mcurrentsens ) )
    {
        log_printf( &logger, " Device calibration success\r\n" );
    }
    else
    {
        log_error( &logger, " Device calibration" );
        for ( ; ; );
    }
#endif
 
    if ( MCURRENTSENS_OK == mcurrentsens_fetch_calib ( &mcurrentsens ) )
    {
        log_printf( &logger, " Calibration data read from EEPROM\r\n" );
    }
    else
    {
        log_error( &logger, " Calibration fetch - No communication with EEPROM or EEPROM is empty" );
        for ( ; ; );
    }
    
    /* Reduce OSR after calibration for faster runtime measurements. */
    mcurrentsens_set_osr( &mcurrentsens, MCURRENTSENS_CONFIG1_OSR_256 );
    
    log_info( &logger, " Application Task " );
}

Application Task

Reads and logs voltage, current, and temperature values continuously.

void application_task ( void )
{
    float ch1_voltage_mv = 0;
    float ch1_current_ma = 0;
    float ch2_voltage_mv = 0;
    float ch2_current_ma = 0;
    float temperature = 0;
 
    if ( MCURRENTSENS_OK == mcurrentsens_read_ch1_voltage( &mcurrentsens, &ch1_voltage_mv ) )
    {
        log_printf( &logger, " CH1 voltage : %.1f mV\r\n", ch1_voltage_mv );
    }
    else
    {
        log_printf( &logger, " CH1 voltage read error\r\n" );
    }
 
    if ( MCURRENTSENS_OK == mcurrentsens_read_ch1_current( &mcurrentsens, &ch1_current_ma ) )
    {
        log_printf( &logger, " CH1 current : %.2f mA\r\n", ch1_current_ma );
    }
    else
    {
        log_printf( &logger, " CH1 current read error\r\n" );
    }
 
    if ( MCURRENTSENS_OK == mcurrentsens_read_ch2_voltage( &mcurrentsens, &ch2_voltage_mv ) )
    {
        log_printf( &logger, " CH2 voltage : %.1f mV\r\n", ch2_voltage_mv );
    }
    else
    {
        log_printf( &logger, " CH2 voltage read error\r\n" );
    }
 
    if ( MCURRENTSENS_OK == mcurrentsens_read_ch2_current( &mcurrentsens, &ch2_current_ma ) )
    {
        log_printf( &logger, " CH2 current : %.2f mA\r\n", ch2_current_ma );
    }
    else
    {
        log_printf( &logger, " CH2 current read error\r\n" );
    }
 
    if ( MCURRENTSENS_OK == mcurrentsens_read_temperature( &mcurrentsens, &temperature ) )
    {
        log_printf( &logger, " Temperature : %.2f degC\r\n", temperature );
    }
    else
    {
        log_printf( &logger, " Temperature read error\r\n" );
    }
 
    log_printf( &logger, "-----------------------------\r\n" );
    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.
