Angle 8 Click

Angle 8 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.

Example Description

This example demonstrates the use of Angle 8 Click board by reading and displaying the magnet's angular position in degrees.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Angle8

Example Key Functions

• angle8_cfg_setup Config Object Initialization function.

void angle8_cfg_setup ( angle8_cfg_t *cfg );

• angle8_init Initialization function.

err_t angle8_init ( angle8_t *ctx, angle8_cfg_t *cfg );

• angle8_default_cfg Click Default Configuration function.

err_t angle8_default_cfg ( angle8_t *ctx );

• angle8_get_nd_pin This function returns the new data ready (ND) pin logic state.

uint8_t angle8_get_nd_pin ( angle8_t *ctx );

• angle8_set_cycle_time This function sets the sensor cycle time (measurement rate) in milliseconds.

err_t angle8_set_cycle_time ( angle8_t *ctx, float time_ms );

• angle8_read_angle This function reads raw angle data and converts it to degrees.

err_t angle8_read_angle ( angle8_t *ctx, float *angle );

Application Init

Initializes the driver and performs the Click default configuration which sets the clockwise rotation direction and cycle time to 100ms.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    angle8_cfg_t angle8_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.
    angle8_cfg_setup( &angle8_cfg );
    ANGLE8_MAP_MIKROBUS( angle8_cfg, MIKROBUS_1 );
    if ( SPI_MASTER_ERROR == angle8_init( &angle8, &angle8_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( ANGLE8_ERROR == angle8_default_cfg ( &angle8 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

Waits for the new data ready flag and then reads the magnet's angular position in degrees and displays the results on the USB UART.

void application_task ( void )
{
    if ( angle8_get_nd_pin ( &angle8 ) )
    {
        float angle = 0;
        if ( ANGLE8_OK == angle8_read_angle ( &angle8, &angle ) )
        {
            log_printf ( &logger, " Angle: %.2f Deg \r\n\n", angle );
        }
    }
}

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.
