AMR Angle 2 Click

AMR Angle 2 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.

• Date : Jul 2022.
• Type : SPI type

Software Support

Example Description

This example demonstrates the use of AMR Angle 2 Click board by reading and displaying the magnet's angular position in Degrees and a system temperature in Celsius.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.AMRAngle2

Example Key Functions

• amrangle2_cfg_setup Config Object Initialization function.

void amrangle2_cfg_setup ( amrangle2_cfg_t *cfg );

• amrangle2_init Initialization function.

err_t amrangle2_init ( amrangle2_t *ctx, amrangle2_cfg_t *cfg );

• amrangle2_default_cfg Click Default Configuration function.

err_t amrangle2_default_cfg ( amrangle2_t *ctx );

• amrangle2_read_angle This function reads a Vsin and Vcos voltages and converts them to angle in Degrees.

err_t amrangle2_read_angle ( amrangle2_t *ctx, float *angle );

• amrangle2_read_temperature This function reads a temperature measurements in Celsius.

err_t amrangle2_read_temperature ( amrangle2_t *ctx, float *temperature );

• amrangle2_read_vsin_vcos This function reads a voltage of sine and cosine differential signal outputs.

err_t amrangle2_read_vsin_vcos ( amrangle2_t *ctx, float *vsin, float *vcos );

Application Init

Initializes the driver and performs the Click default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    amrangle2_cfg_t amrangle2_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.
    amrangle2_cfg_setup( &amrangle2_cfg );
    AMRANGLE2_MAP_MIKROBUS( amrangle2_cfg, MIKROBUS_1 );
    if ( SPI_MASTER_ERROR == amrangle2_init( &amrangle2, &amrangle2_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( AMRANGLE2_ERROR == amrangle2_default_cfg ( &amrangle2 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

Reads the magnet's angular position in degrees and a system temperature in Celsius and displays the results on the USB UART approximately every 100ms.

void application_task ( void )
{
    float angle, temperature;
    if ( AMRANGLE2_OK == amrangle2_read_angle ( &amrangle2, &angle ) ) 
    {
        log_printf( &logger, " Angle: %.2f Degrees\r\n", angle );
    }
    if ( AMRANGLE2_OK == amrangle2_read_temperature ( &amrangle2, &temperature ) ) 
    {
        log_printf( &logger, " Temperature: %.2f C\r\n\n", temperature );
    }
    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.
