3D Hall 7 Click

3D Hall 7 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.

Example Key Functions

• c3dhall7_cfg_setup Config Object Initialization function.

void c3dhall7_cfg_setup ( c3dhall7_cfg_t *cfg );

• c3dhall7_init Initialization function.

err_t c3dhall7_init ( c3dhall7_t *ctx, c3dhall7_cfg_t *cfg );

• c3dhall7_default_cfg Click Default Configuration function.

void c3dhall7_default_cfg ( c3dhall7_t *ctx );

void c3dhall7_get_axis_data ( c3dhall7_t *ctx, T_C3DHALL7_AXIS *axis );

• c3dhall7_get_status Measurement status function.

void c3dhall7_get_status ( c3dhall7_t *ctx, T_C3DHALL7_STATUS *status );

• c3dhall7_get_status Measurement status function.

void c3dhall7_get_status ( c3dhall7_t *ctx, T_C3DHALL7_STATUS *status );

Application Init

Initializes driver init, test communication and configuration device for measurement.

void application_init ( c3dhall7_t *ctx, void )
{
    c3dhall7_dev_info_t info;

    log_cfg_t log_cfg;
    c3dhall7_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.

    c3dhall7_cfg_setup( &cfg );
    C3DHALL7_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    c3dhall7_init( &c3dhall7, &cfg );

    c3dhall7_device_reset( &c3dhall7 );
    Delay_ms ( 1000 );
    c3dhall7_read_data( &c3dhall7, 0x01, &red_data, 1 );

    Delay_100ms( );

    for ( ; ; );
    // Test communication 
    c3dhall7_deviceInfo( &info );
    if ( info.device_id == C3DHALL7_DEVICE_ID )
    {
        mikrobus_logW_write( "---- Communication [ OK ]!!! ----", LOG_LINE );
    }
    else
    {
        mikrobus_log_write( "---- Communication [ ERROR ]!!! ----", LOG_LINE );

        for ( ; ; );
    }

    // Configuration 
    c3dhall7_default_cfg ( &c3dhall7 );
}

Application Task

Reads 3 Axis of the magnetic sensor and logs this data to USBUART every 500ms.

void application_task ( void )
{
    c3dhall7_axix_t axis;

    char demo_text[ 50 ];
    
    c3dhall7_get_axis_data( &axis );
    
    mikrobus_log_write( "---- Measurement data of magnetic sensor ----", LOG_LINE );
    
    log_printf( &logger, "X axis: %d \r\n", axis.x );

    log_printf( &logger, "Y axis: %d \r\n", axis.y );

    log_printf( &logger, "Z axis: %d \r\n", axis.z );
    
    mikrobus_log_write( "---------------------------------------------", LOG_LINE);
    Delay_ms ( 500 );
}

Note

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.
