Magneto 10 Click

Magneto 10 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 10 Click board.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Magneto10

Example Key Functions

• magneto10_cfg_setup Config Object Initialization function.

void magneto10_cfg_setup ( magneto10_cfg_t *cfg );

• magneto10_init Initialization function.

err_t magneto10_init ( magneto10_t *ctx, magneto10_cfg_t *cfg );

• magneto10_default_cfg Click Default Configuration function.

err_t magneto10_default_cfg ( magneto10_t *ctx );

• magneto10_get_magnetic_flux This function reads the raw values of X, Y, and Z axis and converts them to magnetic flux data in microTesla.

err_t magneto10_get_magnetic_flux ( magneto10_t *ctx, float *x_axis, float *y_axis, float *z_axis );

• magneto10_get_temperature This function reads the raw temperature value and converts it to Celsius.

err_t magneto10_get_temperature ( magneto10_t *ctx, float *temperature );

• magneto10_set_operating_mode This function sets the device operating mode.

err_t magneto10_set_operating_mode ( magneto10_t *ctx, uint8_t mode );

Application Init

Initializes the driver and performs the Click default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;              /**< Logger config object. */
    magneto10_cfg_t magneto10_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.
    magneto10_cfg_setup( &magneto10_cfg );
    MAGNETO10_MAP_MIKROBUS( magneto10_cfg, MIKROBUS_1 );
    
    if ( I2C_MASTER_ERROR == magneto10_init( &magneto10, &magneto10_cfg ) ) 
    {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );
        for ( ; ; );
    }
    
    if ( MAGNETO10_ERROR == magneto10_default_cfg( &magneto10 ) ) 
    {
        log_error( &logger, " Default Config Error. " );
        log_info( &logger, " Please, run program again... " );
        for ( ; ; );
    }
    log_info( &logger, " Application Task " );
}

Application Task

Reads the magnetic flux as well as the internal temperature data every 100ms and displays the results on the USB UART.

void application_task ( void )
{
    float x_axis, y_axis, z_axis, temperature;
    if ( MAGNETO10_OK == magneto10_get_magnetic_flux ( &magneto10, &x_axis, &y_axis, &z_axis ) )
    {
        log_printf( &logger, " X-axis: %.2f uT\r\n Y-axis: %.2f uT\r\n Z-axis: %.2f uT\r\n", 
                    x_axis, y_axis, z_axis );
    }
    if ( MAGNETO10_OK == magneto10_get_temperature ( &magneto10, &temperature ) )
    {
        log_printf( &logger, " Internal temperature: %.2f C\r\n\n", temperature );
    }
    Delay_ms ( 100 );
}

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.
