Hall Current 7 Click is a compact add-on board that provides economical and precise solutions for AC or DC current sensing. This board features the ACS770, a thermally enhanced, fully integrated, Hall effect-based high precision linear current sensor with 100µΩ current conductor from Allegro MicroSystems. Applied current flows directly into the integrated conductor generating a magnetic field, and an integrated low-hysteresis core concentrates the magnetic field sensed by the Hall element with a typical accuracy of ±1% and 120 kHz bandwidth.

Click library

  • Author : Stefan Ilic
  • Date : Aug 2021.
  • Type : I2C type

Software Support

We provide a library for the HallCurrent7 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 HallCurrent7 Click driver.

Standard key functions :

  • hallcurrent7_cfg_setup Config Object Initialization function.

    void hallcurrent7_cfg_setup ( hallcurrent7_cfg_t *cfg );
  • hallcurrent7_init Initialization function.

    err_t hallcurrent7_init ( hallcurrent7_t *ctx, hallcurrent7_cfg_t *cfg );

Example key functions :

  • hallcurrent7_read_voltage Read voltage function.

    uint16_t hallcurrent7_read_voltage ( hallcurrent7_t *ctx, uint16_t v_ref );
  • hallcurrent7_calc_current Calculate current function.

    int16_t hallcurrent7_calc_current ( hallcurrent7_t *ctx, uint16_t v_ref );
  • hallcurrent7_avg_current Calculate Average current function.

    int16_t hallcurrent7_avg_current ( hallcurrent7_t *ctx, uint16_t v_ref );

Example Description

This example shows the capabilities of the Hall Current 7 Click board.

The demo application is composed of two sections :

Application Init

Initalizes I2C driver and makes an initial log.


void application_init ( void ) {
    log_cfg_t log_cfg;  /**< Logger config object. */
    hallcurrent7_cfg_t hallcurrent7_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.
    hallcurrent7_cfg_setup( &hallcurrent7_cfg );
    HALLCURRENT7_MAP_MIKROBUS( hallcurrent7_cfg, MIKROBUS_1 );
    err_t init_flag = hallcurrent7_init( &hallcurrent7, &hallcurrent7_cfg );
    if ( I2C_MASTER_ERROR == init_flag ) {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }

    log_info( &logger, " Application Task " );
}

Application Task

Measuring current passing through the on board Hall Effect Sensor and displaying data every two seconds.


void application_task ( void ) {
    current = hallcurrent7_avg_current( &hallcurrent7, HALLCURRENT7_VREF_5000_mV );
    log_printf( &logger, "Current: %d mA\r\n", current );

    log_printf( &logger, "------------------------\r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}

Note

In order to get correct calculations user should change "v_ref" value to his own power supply voltage.

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.HallCurrent7

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.

BATT-MON 2 Click is a compact add-on board representing a battery monitoring solution. This board features the MAX17262, an ultra-low power I2C-configurable fuel-gauge IC which implements the ModelGauge™ m5 algorithm from Analog Devices. The MAX17262 monitors a single-cell battery pack (best performance for batteries with 100mAhr to 6Ahr capacity), providing precision measurements of current, voltage, and temperature, and supporting internal current sensing for up to 3.1A pulse current. The battery pack's temperature is measured using an internal temperature sensor or external thermistor.
