Angle 7 Click

Angle 7 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 7 Click board by reading and displaying the magnet's angular position in degrees and analog voltage output as well as the magnet's status and magnitude.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Angle7

Example Key Functions

• angle7_cfg_setup Config Object Initialization function.

void angle7_cfg_setup ( angle7_cfg_t *cfg );

• angle7_init Initialization function.

err_t angle7_init ( angle7_t *ctx, angle7_cfg_t *cfg );

• angle7_default_cfg Click Default Configuration function.

err_t angle7_default_cfg ( angle7_t *ctx );

• angle7_get_status This function reads the status data.

err_t angle7_get_status ( angle7_t *ctx, uint8_t *status );

• angle7_get_angle This function reads the calculated angle in degrees.

err_t angle7_get_angle ( angle7_t *ctx, float *angle );

• angle7_get_magnitude This function reads the magnitude data.

err_t angle7_get_magnitude ( angle7_t *ctx, uint16_t *magnitude );

Application Init

Initializes the driver and performs the Click default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    angle7_cfg_t angle7_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.
    angle7_cfg_setup( &angle7_cfg );
    ANGLE7_MAP_MIKROBUS( angle7_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == angle7_init( &angle7, &angle7_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( ANGLE7_ERROR == angle7_default_cfg ( &angle7 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

Reads the magnet's angular position in degrees and analog voltage output as well as the magnet's status and magnitude and displays the results on the USB UART approximately every 100ms.

void application_task ( void )
{
    float voltage, raw_angle, angle;
    uint16_t magnitude;
    uint8_t status;
    if ( ADC_ERROR != angle7_read_an_pin_voltage ( &angle7, &voltage ) ) 
    {
        log_printf( &logger, " AN voltage: %.3f V\r\n", voltage );
    }
    if ( ANGLE7_OK == angle7_get_angle ( &angle7, &angle ) )
    {
        log_printf ( &logger, " Angle: %.2f Degrees\r\n", angle );
    }
    if ( ANGLE7_OK == angle7_get_magnitude ( &angle7, &magnitude ) )
    {
        log_printf ( &logger, " Magnitude: %u\r\n", magnitude );
    }
    if ( ANGLE7_OK == angle7_get_status ( &angle7, &status ) )
    {
        log_printf ( &logger, " Status:" );
        if ( status & ANGLE7_STATUS_MAGNET_DETECTED )
        {
            log_printf ( &logger, " Magnet Detected \r\n Magnet Strength:" );
            if ( status & ANGLE7_STATUS_MAGNET_TOO_STRONG )
            {
                log_printf ( &logger, " Too Strong \r\n\n" );
            }
            else if ( status & ANGLE7_STATUS_MAGNET_TOO_WEAK )
            {
                log_printf ( &logger, " Too Weak \r\n\n" );
            }
            else
            {
                log_printf ( &logger, " Good \r\n\n" );
            }
        }
        else
        {
            log_printf ( &logger, " Magnet Not Detected \r\n\n" );
        }
    }
    Delay_ms ( 100 );
}

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.
