Angle 5 click

Angle 5 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.

Click library

• Author : MikroE Team
• Date : sep 2020.
• Type : SPI type

Software Support

We provide a library for the Angle5 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 Angle5 Click driver.

Standard key functions :

• Config Object Initialization function.

void angle5_cfg_setup ( angle5_cfg_t *cfg );

• Initialization function.

ANGLE5_RETVAL angle5_init ( angle5_t *ctx, angle5_cfg_t *cfg );

Example key functions :

• Use this function to read raw angle data

uint16_t angle5_read_raw_angle ( angle5_t *ctx );

• Use this function to read angle data

float angle5_read_angle_deg ( angle5_t *ctx );

Examples Description

Angle 5 click is a magnetic rotational sensor. It communicates with the target microcontroller over SPI interface.

The demo application is composed of two sections :

Application Init

Initializes the driver.

void application_init ( void )
{
    log_cfg_t log_cfg;
    angle5_cfg_t cfg;

    /** 
     * 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.

    angle5_cfg_setup( &cfg );
    ANGLE5_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    angle5_init( &angle5, &cfg );
}
  

Application Task

Reads the angle position of the magnet and displays the results on the USB UART.

void application_task ( void )
{
    float new_angle = 0;
    
    new_angle = angle5_read_angle_deg( &angle5 );
    log_printf( &logger, "Angle: %.2f\r\n", new_angle );

    Delay_ms ( 100 );
} 

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.Angle5

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.
