Magneto 7 Click

Magneto 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.

• Date : Dec 2019.
• Type : I2C type

Software Support

Example Description

This demo application reads position of a magnet above the sensor.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Magneto7

Example Key Functions

• magneto7_cfg_setup Config Object Initialization function.

void magneto7_cfg_setup ( magneto7_cfg_t *cfg );

• magneto7_init Initialization function.

err_t magneto7_init ( magneto7_t *ctx, magneto7_cfg_t *cfg );

• magneto7_default_cfg Click Default Configuration function.

void magneto7_default_cfg ( magneto7_t *ctx );

• magneto7_int_get This function returns INT pin state.

uint8_t magneto7_int_get ( magneto7_t *ctx );

• magneto7_get_register This function gets register value(s).

uint8_t magneto7_get_register ( magneto7_t *ctx, uint8_t register_address, uint8_t * data_buffer, uint8_t n_data );

• magneto7_get_temperature This function gets raw device temperature value.

void magneto7_get_temperature ( magneto7_t *ctx, uint16_t *device_temperature );

Application Init

Initializes device.

void application_init ( void )
{
    log_cfg_t log_cfg;
    magneto7_cfg_t cfg;
    uint8_t init_status;

    /** 
     * 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 ----\r\n" );

    //  Click initialization.

    magneto7_cfg_setup( &cfg );
    MAGNETO7_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    magneto7_init( &magneto7, &cfg );
    Delay_ms ( 300 );

    init_status = magneto7_default_cfg( &magneto7 );
    if ( init_status == 0)
    {
        log_printf( &logger, "> app init done\r\n" );
    }
    else if ( init_status == 1 )
    {
        log_printf( &logger, "> app init fail\r\n" );
        for ( ; ; );
    }
}

Application Task

Waits for INT pin to go LOW, gets raw data, converts it to uT and logs results.

void application_task ( void )
{
    uint8_t int_status;
    float converted_data;

    int16_t data_x;
    int16_t data_y;
    int16_t data_z;

    int_status = magneto7_int_get( &magneto7 );
    
    if ( int_status == 0 )
    {
        magneto7_get_data( &magneto7, &data_x, &data_y, &data_z );
        
        converted_data = magneto7_convert_to_ut( &magneto7, data_x, MAGNETO7_SENSOR_RES_14_BIT );
        log_printf( &logger, "> X Axis : %f [uT]\r\n", converted_data );
        
        converted_data = magneto7_convert_to_ut( &magneto7, data_y, MAGNETO7_SENSOR_RES_14_BIT );
        log_printf( &logger, "> Y Axis : %f [uT]\r\n", converted_data );

        converted_data = magneto7_convert_to_ut( &magneto7, data_z, MAGNETO7_SENSOR_RES_14_BIT );
        log_printf( &logger, "> Z Axis : %f [uT]\r\n", converted_data );

        log_printf( &logger, "\r\n" );
        
        Delay_ms ( 300 );
    }
}

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.
