Magnetic Rotary 2 Click is a compact add-on board used for accurate magnet-position sensing. This board features the AEAT-9922, an angular magnetic rotary sensor providing accurate angular measurement over a full 360 degrees of rotation from Broadcom Limited. The AEAT-9922 uses integrated Hall sensor elements with complex analog and digital signal processing within a single device. The absolute angle measurement provides an instant indication of the magnet's angular position with a selectable and one-time programmable resolution from 10 to 18 bits.

Click library

  • Author : Stefan Filipovic
  • Date : Oct 2021.
  • Type : SPI type

Software Support

We provide a library for the MagneticRotary2 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 MagneticRotary2 Click driver.

Standard key functions :

  • magneticrotary2_cfg_setup Config Object Initialization function.

    void magneticrotary2_cfg_setup ( magneticrotary2_cfg_t *cfg );
  • magneticrotary2_init Initialization function.

    err_t magneticrotary2_init ( magneticrotary2_t *ctx, magneticrotary2_cfg_t *cfg );
  • magneticrotary2_default_cfg Click Default Configuration function.

    err_t magneticrotary2_default_cfg ( magneticrotary2_t *ctx );

Example key functions :

  • magneticrotary2_write_register This function writes a data byte to the selected register by using SPI serial interface.

    err_t magneticrotary2_write_register ( magneticrotary2_t *ctx, uint8_t reg, uint8_t data_in );
  • magneticrotary2_read_register This function reads a data byte from the selected register by using SPI serial interface.

    err_t magneticrotary2_read_register ( magneticrotary2_t *ctx, uint8_t reg, uint8_t *data_out );
  • magneticrotary2_get_angle This function reads the absolute position raw data and converts it to degrees (Angle).

    err_t magneticrotary2_get_angle ( magneticrotary2_t *ctx, float *angle );

Example Description

This example demonstrates the use of Magnetic Rotary 2 Click board by reading and displaying the magnet's angular position in degrees.

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. */
    magneticrotary2_cfg_t magneticrotary2_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.
    magneticrotary2_cfg_setup( &magneticrotary2_cfg );
    MAGNETICROTARY2_MAP_MIKROBUS( magneticrotary2_cfg, MIKROBUS_1 );
    if ( SPI_MASTER_ERROR == magneticrotary2_init( &magneticrotary2, &magneticrotary2_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    if ( MAGNETICROTARY2_ERROR == magneticrotary2_default_cfg ( &magneticrotary2 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    log_info( &logger, " Application Task " );
}

Application Task

Reads the magnet's angular position in degrees every 100ms and displays the results on the USB UART.


void application_task ( void )
{
    float angle = 0;

    if ( MAGNETICROTARY2_OK == magneticrotary2_get_angle ( &magneticrotary2, &angle ) )
    {
        log_printf( &logger, " Angle: %.2f degrees\r\n\n", angle );
        Delay_ms ( 100 );
    }
}

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.MagneticRotary2

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.

Ambient 22 Click

0

Ambient 22 Click is a compact add-on board that measures the intensity of visible light. This board features the OPT3005, a single-chip lux meter from Texas Instruments that transforms light intensity to a digital signal output that can be directly communicated via an I2C interface. The sensor's spectral response tightly matches the human eye's photopic response along with extreme rejection to 850nm and 940nm infrared light over a wide angle of incidence. Measurements can be made from 20mlux up to 166klux without manually selecting full-scale ranges using the built-in, full-scale setting feature.

Speed Sense Click is a compact add-on board that allows you to measure the speed and rotation of a spinning object. This board features the A17501, a dual output differential speed and direction sensor from Allegro Microsystems. It has a high-speed switching bandwidth of up to 40kHz for two different signals. The sensor has two independent output channels with options for high-resolution XOR speed, pulse, and direction protocol.
