Magneto 11 Click

Magneto 11 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 Description

This example demonstrates the use of Magneto 11 Click board by reading and displaying the magnetic field strength value.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Magneto11

Example Key Functions

• magneto11_cfg_setup Config Object Initialization function.

void magneto11_cfg_setup ( magneto11_cfg_t *cfg );

• magneto11_init Initialization function.

err_t magneto11_init ( magneto11_t *ctx, magneto11_cfg_t *cfg );

• magneto11_default_cfg Click Default Configuration function.

err_t magneto11_default_cfg ( magneto11_t *ctx );

• magneto11_get_magnetic_field This function reads the magnetic field strength in milliTesla.

err_t magneto11_get_magnetic_field ( magneto11_t *ctx, float *mag_field );

• magneto11_set_sensitivity This function writes specified data to the sensitivity register.

err_t magneto11_set_sensitivity ( magneto11_t *ctx, uint8_t sensitivity );

• magneto11_set_config This function writes specified data to the config register.

err_t magneto11_set_config ( magneto11_t *ctx, uint8_t config );

Application Init

Initializes the driver and performs the Click default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    magneto11_cfg_t magneto11_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.
    magneto11_cfg_setup( &magneto11_cfg );
    MAGNETO11_MAP_MIKROBUS( magneto11_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == magneto11_init( &magneto11, &magneto11_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( MAGNETO11_ERROR == magneto11_default_cfg ( &magneto11 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

Reads the magnetic field strength value in milliTesla and displays the results on the USB UART every 200ms approximately.

void application_task ( void )
{
    float magnetic_field;
    if ( MAGNETO11_OK == magneto11_get_magnetic_field ( &magneto11, &magnetic_field ) )
    {
        log_printf ( &logger, " Magnetic Field: %.3f mT \r\n\n", magnetic_field );
        Delay_ms ( 200 );
    }
}

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.
