Angle 4 Click

Angle 4 Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Click Library

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

Software Support

Example Description

This application enables use of angular magnetic rotary sensor, which can be used as a rotary encoder.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Angle4

Example Key Functions

• angle4_cfg_setup Config Object Initialization function.

void angle4_cfg_setup ( angle4_cfg_t *cfg );

• angle4_init Initialization function.

err_t angle4_init ( angle4_t *ctx, angle4_cfg_t *cfg );

• angle4_default_cfg Click Default Configuration function.

void angle4_default_cfg ( angle4_t *ctx );

• angle4_start_mesuremenet function used to start measurement mode.

void angle4_start_mesuremenet ( angle4_t *ctx );

• angle4_get_new_angle This function is used to retrieve Angle value depending on the given resolution.

uint8_t angle4_get_new_angle ( angle4_t *ctx, uint16_t *data_out );

• angle4_read_byte This function is used to read single byte of Data on the desired address.

uint8_t angle4_read_byte ( angle4_t *ctx, uint8_t addr );

Application Init

Driver intialization, standard configurations and start measurement

void application_init ( void )
{
    log_cfg_t log_cfg;
    angle4_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.

    angle4_cfg_setup( &cfg );
    ANGLE4_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    angle4_init( &angle4, &cfg );

    angle4_default_cfg( &angle4, ANGLE4_CCFG2_DIR_COUNTER_CLOCKWISE_ROTATION,\
                                 ANGLE4_CCFG2_ABS_RESOLUTION_14bit );
    log_printf( &logger, " --- Start measurement \r\n");

    angle4_start_mesuremenet( &angle4 );
}

Application Task

Reads Angle in degreeses and logs data to USBUART every 200 ms.

void application_task ( void )
{
    //  Task implementation.

    uint16_t angle_value;

    angle4_get_new_angle( &angle4, &angle_value );
    log_printf( &logger, " Angle : %d deg\r\n", angle_value );
    Delay_ms ( 200 );
}

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
