Click library

  • Author : MikroE Team
  • Date : Dec 2019.
  • Type : I2C type

Software Support

We provide a library for the Magneto7 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for Magneto7 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void magneto7_cfg_setup ( magneto7_cfg_t *cfg );

  • Initialization function.

    MAGNETO7_RETVAL magneto7_init ( magneto7_t ctx, magneto7_cfg_t cfg );

  • Click Default Configuration function.

    void magneto7_default_cfg ( magneto7_t *ctx );

Example key functions :

  • This function returns INT pin state

    uint8_t magneto7_int_get ( magneto7_t *ctx );

  • 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 );

  • This function gets raw device temperature value.

    void magneto7_get_temperature ( magneto7_t ctx, uint16_t device_temperature );

Examples Description

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

The demo application is composed of two sections :

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 );
    }
}

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

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

Additional notes and informations

Depending on the development board you are using, you may need USB UART Click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
