Angle 6 Click is a compact add-on board that detects the absolute angular position of a permanent magnet, typically a diametrically magnetized cylinder on a rotating shaft. This board features the MAQ470GQE, a 12-bit contactless angle sensor with PWM output from Monolithic Power Systems. It supports a wide range of magnetic field strengths and spatial configurations, with both end-of-shaft and off-axis (side-shaft mounting), supported configurations. Fast data acquisition and processing provides accurate angle measurement at speeds from 0 to 60,000 rpm, alongside magnetic field strength detection with programmable thresholds.

Click library

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

Software Support

We provide a library for the Angle 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 Angle 6 Click driver.

Standard key functions :

  • angle6_cfg_setup Config Object Initialization function.

    void angle6_cfg_setup ( angle6_cfg_t *cfg );
  • angle6_init Initialization function.

    err_t angle6_init ( angle6_t *ctx, angle6_cfg_t *cfg );
  • angle6_default_cfg Click Default Configuration function.

    err_t angle6_default_cfg ( angle6_t *ctx );

Example key functions :

  • angle6_write_register This function writes a data byte to the selected register by using SPI serial interface.

    err_t angle6_write_register ( angle6_t *ctx, uint8_t reg, uint8_t data_in );
  • angle6_read_register This function reads a data byte from the selected register by using SPI serial interface.

    err_t angle6_read_register ( angle6_t *ctx, uint8_t reg, uint8_t *data_out );
  • angle6_read_angle This function reads raw angle data and converts it to degrees.

    err_t angle6_read_angle ( angle6_t *ctx, float *angle );

Example Description

This example demonstrates the use of Angle 6 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 which sets the rotation direction to clockwise.


void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    angle6_cfg_t angle6_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.
    angle6_cfg_setup( &angle6_cfg );
    ANGLE6_MAP_MIKROBUS( angle6_cfg, MIKROBUS_1 );
    if ( SPI_MASTER_ERROR == angle6_init( &angle6, &angle6_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    if ( ANGLE6_ERROR == angle6_default_cfg ( &angle6 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

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

Application Task

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

void application_task ( void )
{
    float angle = 0;
    if ( ANGLE6_OK == angle6_read_angle ( &angle6, &angle ) )
    {
        log_printf ( &logger, " Angle: %.2f Deg \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.Angle6

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.

Button G click

1

Button G click is the simplest solution for adding a single pushbutton to your design. The button itself is transparent, 6.8mm in diameter and has a green LED backlight. When pressed, it sends an interrupt signal to the target board microcontroller. The backlight LED is controlled separately through the mikroBUSâ„¢ PWM pin.
