Click library

  • Author : Stefan Ilic
  • Date : Feb 2024.
  • Type : ADC type

Software Support

We provide a library for the Hall Current 19 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 Hall Current 19 Click driver.

Standard key functions :

  • hallcurrent19_cfg_setup Config Object Initialization function.

    void hallcurrent19_cfg_setup ( hallcurrent19_cfg_t *cfg );
  • hallcurrent19_init Initialization function.

    err_t hallcurrent19_init ( hallcurrent19_t *ctx, hallcurrent19_cfg_t *cfg );

Example key functions :

  • hallcurrent19_get_oc2 This function is used to get state of the overcurrent 2 detection of the Hall Current 19 Click board.

    uint8_t hallcurrent19_get_oc2 ( hallcurrent19_t *ctx );
  • hallcurrent19_set_zero_ref This function sets the zero voltage reference of the Hall Current 19 Click board.

    err_t hallcurrent19_set_zero_ref ( hallcurrent19_t *ctx );
  • hallcurrent19_get_current This function reads and calculate input current value of the Hall Current 19 Click board.

    err_t hallcurrent19_get_current ( hallcurrent19_t *ctx, float *current );

Example Description

This example demonstrates the use of Hall Current 19 Click board by reading and displaying the current measurements.

The demo application is composed of two sections :

Application Init

Initializes the driver and logger, and set the zero voltage reference.


void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    hallcurrent19_cfg_t hallcurrent19_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.
    hallcurrent19_cfg_setup( &hallcurrent19_cfg );
    HALLCURRENT19_MAP_MIKROBUS( hallcurrent19_cfg, MIKROBUS_1 );
    if ( ADC_ERROR == hallcurrent19_init( &hallcurrent19, &hallcurrent19_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    log_printf( &logger, " Turn off the load current in the following 5 sec.\r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    if ( HALLCURRENT19_OK == hallcurrent19_set_zero_ref( &hallcurrent19 ) )
    {
        log_printf( &logger, " Process complete!\r\n");
    }
    else
    {
        log_error( &logger, " Zero reference." );
        for ( ; ; );
    }

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

Application Task

The demo application reads the current measurements [A] and displays the results. Results are being sent to the UART Terminal, where you can track their changes.


void application_task ( void ) 
{
    float voltage = 0;
    if ( HALLCURRENT19_OK == hallcurrent19_get_current ( &hallcurrent19, &voltage ) ) 
    {
        log_printf( &logger, " Current : %.3f[A]\r\n\n", voltage );
        Delay_ms ( 1000 );
    }
    if ( HALLCURRENT19_OCD_ACTIVE == hallcurrent19_get_oc1( &hallcurrent19 ) )
    {
        log_printf( &logger, " Current over 7A \r\n" );
    }
    if ( HALLCURRENT19_OCD_ACTIVE == hallcurrent19_get_oc2( &hallcurrent19 ) )
    {
        log_printf( &logger, " Current over 17.5A \r\n" );
    }
}

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.HallCurrent19

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.

HAPTIC 2 Click is a compact add-on board that contains a linear vibration driver. This board features the LC898302AXA, a motor driver dedicated to LRA and ERM applications from ON Semiconductor. Controlled by only one pin, it allows crisp vibration thanks to automatic braking and over-driving feature and ignores the deviation of resonance frequency thanks to auto-tuning function. The original driving waveform will enable you to reduce power consumption, and it is helpful to maintain battery lifetime. This Click board™ is suitable for numerous everyday applications such as indicator systems, game consoles, training equipment/simulators with haptics function, robotics and mechatronics, and many more.
