Angle click

Angle click is a precise Hall-effect angle sensing click board that can be used to measure the rotational angle of the magnetic field in the X-Y plane above it (parallel to the surface of the click), through the whole range of 360°. The click yields very precise results for both off-axis and axis operation, which make it a perfect choice for precise measuring of the rotational angle in a wide range of different high-speed applications, for example in the automotive industry: electronic power steering, transmission, torsion bar, or the motor shaft rotation.

Click library

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

Software Support

We provide a library for the Angle 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 Angle Click driver.

Standard key functions :

• Config Object Initialization function.

  ‍void angle_cfg_setup ( angle_cfg_t *cfg );

  - Initialization function.

  ‍ANGLE_RETVAL angle_init ( angle_t *ctx, angle_cfg_t *cfg );

• Click Default Configuration function.

  ‍void angle_default_cfg ( angle_t *ctx );

Example key functions :

• This function reads angle value.

  ‍uint16_t angle_get_angle ( angle_t *ctx );

  - This function reads temperature value.

  ‍uint16_t angle_get_temperature ( angle_t *ctx );

• This function reads magnetics value.

  ‍uint16_t angle_get_magnetics ( angle_t *ctx );

Examples Description

‍Angle click is a precise Hall-effect angle sensing click board that can be used to measure the rotational angle of the magnetic field in the X-Y plane above it.

The demo application is composed of two sections :

Application Init

‍Driver intialization and Angle settings mode

void application_init ( void )
{
    log_cfg_t log_cfg;
    angle_cfg_t cfg;
 
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, "---- Application Init ----" );
 
    //  Click initialization.
 
    angle_cfg_setup( &cfg );
    ANGLE_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    angle_init( &angle, &cfg );
    angle_default_cfg ( &angle );
}

Application Task

‍Reads angle and magnetics data values and displays it in the terminal.

void application_task ( void )
{
    angle_val = angle_get_angle( &angle );
    log_printf( &logger, "Angle :%d \r\n", angle_val );
    
    magnetics_val = angle_get_magnetics( &angle );
    log_printf( &logger, "Magnetics :%d \r\n", magnetics_val );
    
    Delay_ms ( 1000 );
}

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.Angle

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.
