Magneto 6 Click features low power three dimensional Hall effect sensor, TLI493D-A2B6, designed for magnetic sensing applications. It measures the magnetic field in X, Y, and Z direction. Each X, Y and Z Hall probe is connected sequentially to a multiplexer, which is then connected to an Analog to Digital Converter (ADC). Optional, the temperature can be determined as well after the three Hall channels. The data measurement is provided in digital format to the microcontroller over the standard I2C interface. Some of the benefits of this Click board™ are wide application range addressable due to high flexibility and component reduction due to the 3D magnetic measurement principle.

Click library

  • Author : Stefan Filipovic
  • Date : Feb 2024.
  • Type : I2C type

Software Support

We provide a library for the Magneto 6 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 from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for Magneto 6 Click driver.

Standard key functions :

  • magneto6_cfg_setup Config Object Initialization function.

    void magneto6_cfg_setup ( magneto6_cfg_t *cfg );
  • magneto6_init Initialization function.

    err_t magneto6_init ( magneto6_t *ctx, magneto6_cfg_t *cfg );
  • magneto6_default_cfg Click Default Configuration function.

    err_t magneto6_default_cfg ( magneto6_t *ctx );

Example key functions :

  • magneto6_read_data This function reads the measurements of the 3-axes magnetic field sensor in mT and the temperature sensor in degrees Celsius.

    err_t magneto6_read_data ( magneto6_t *ctx, magneto6_data_t *data_out );
  • magneto6_read_reg This function reads a desired number of data bytes starting from the selected register by using I2C serial interface.

    err_t magneto6_read_reg ( magneto6_t *ctx, uint8_t reg, uint8_t *data_out, uint8_t len );
  • magneto6_write_reg This function writes a data byte to the selected register by using I2C serial interface.

    err_t magneto6_write_reg ( magneto6_t *ctx, uint8_t reg, uint8_t data_in );

Example Description

This example demonstrates the use of Magneto 6 Click board by reading the magnetic field strength from 3 axes as well as the ambient temperature measurements.

The demo application is composed of two sections :

Application Init

Initializes the driver and performs the Click default configuration.


void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    magneto6_cfg_t magneto6_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.
    magneto6_cfg_setup( &magneto6_cfg );
    MAGNETO6_MAP_MIKROBUS( magneto6_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == magneto6_init( &magneto6, &magneto6_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    if ( MAGNETO6_ERROR == magneto6_default_cfg ( &magneto6 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

    log_info( &logger, " Application Task " );
}

Application Task

Reads data from the sensor and displays them on the USB UART once per second.

void application_task ( void )
{
    magneto6_data_t data_res;
    if ( MAGNETO6_OK == magneto6_read_data ( &magneto6, &data_res ) )
    {
        log_printf( &logger, " X data: %.1f mT\r\n", data_res.x_data );
        log_printf( &logger, " Y data: %.1f mT\r\n", data_res.y_data );
        log_printf( &logger, " Z data: %.1f mT\r\n", data_res.z_data );
        log_printf( &logger, " Temperature: %.2f degC\r\n\n", data_res.temperature );
    }
    Delay_ms ( 1000 );
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Magneto6

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. UART terminal is available in all MikroElektronika compilers.

MUX 9 Click

MUX 9 Click is a compact add-on board that contains a precise multiplexing solution. This board features the ADG1438, a CMOS 8-channel analog matrix switch with a high-speed serially controlled 4-wire interface from Analog Devices. Each switch is software-controlled (by a bit of the appropriate register) and conducts equally well in both directions, making it ideal for mux/demux applications. It is specified for a wide supply range ±15V/+12V/±5V where all channels exhibit break-before-make switching action, preventing momentary shorting when switching channels.
