Hall Current 2 Click

Hall Current 2 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.

• Type : I2C type

Software Support

Example Description

This application very accurately measures current using Hall effect.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.HallCurrent2

Example Key Functions

• hallcurrent2_cfg_setup Config Object Initialization function.

void hallcurrent2_cfg_setup ( hallcurrent2_cfg_t *cfg );

• hallcurrent2_init Initialization function.

err_t hallcurrent2_init ( hallcurrent2_t *ctx, hallcurrent2_cfg_t *cfg );

• hallcurrent2_default_cfg Click Default Configuration function.

void hallcurrent2_default_cfg ( hallcurrent2_t *ctx );

• hallcurrent2_generic_read This function reads data from the desired register.

void hallcurrent2_generic_read ( hallcurrent2_t *ctx );

• hallcurrent2_reset This function changes reset chip states to reset the chip.

void hallcurrent2_reset ( hallcurrent2_t *ctx );

• hallcurrent2_get_current Reads current's value in mV.

int16_t hallcurrent2_get_current ( hallcurrent2_t *ctx );

Application Init

Initializes Driver init and reset chip

void application_init ( void )
{
    log_cfg_t log_cfg;
    hallcurrent2_cfg_t cfg;

    /** 
     * 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.

    hallcurrent2_cfg_setup( &cfg );
    HALLCURRENT2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    hallcurrent2_init( &hallcurrent2, &cfg );

    hallcurrent2_reset( &hallcurrent2 );
}

Application Task

Reads current and logs on usbuart every 1 second.

void application_task ( void )
{
    int16_t current_data;

    current_data = hallcurrent2_get_current( &hallcurrent2 );
    log_printf( &logger, "--- Current : %d mA\r\n", current_data );
    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.
