Angle 2 Click

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.

Click Library

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

Software Support

Example Description

This example showcases how to configure and use the Angle 2 Click. This Click senses the magnetic field along the horizontal plane using an array of Hal effect sensors. The module uses advanced Spinaxis technology based on a direct angle sampling app- roach in order to provide reliable data quickly.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Angle2

Example Key Functions

• angle2_cfg_setup Config Object Initialization function.

void angle2_cfg_setup ( angle2_cfg_t *cfg );

• angle2_init Initialization function.

err_t angle2_init ( angle2_t *ctx, angle2_cfg_t *cfg );

• angle2_default_cfg Click Default Configuration function.

void angle2_default_cfg ( angle2_t *ctx );

• angle2_get_angle This function reads angle data from the Click module.

double angle2_get_angle ( angle2_t *ctx );

• angle2_get_angle_with_time_index This function reads angle and time index data from the Click module.

double angle2_get_angle_with_time_index ( angle2_t *ctx, uint8_t *time_index );

• angle2_set_zero_scale This function sets the zero scale value.

void angle2_set_zero_scale ( angle2_t *ctx, double zero_deg );

Application Init

This function initializes and configures the Click and logger modules. Additional con- figuring is done in the default_cfg(...) function.

void application_init ( void )
{
    log_cfg_t log_cfg;
    angle2_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 ----" );
    Delay_ms ( 100 );

    //  Click initialization.

    angle2_cfg_setup( &cfg );
    ANGLE2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    angle2_init( &angle2, &cfg );

    Delay_ms ( 300 );
    angle2_default_cfg( &angle2 );
    Delay_ms ( 200 );

    log_printf( &logger, " * Angle 2 initialized * \r\n" );
}

Application Task

This function reads angle data from the Click module and displays that data using the UART console every 200 miliseconds.

void application_task ( void )
{
    double angle;

    angle = angle2_get_angle( &angle2 );

    log_printf( &logger, " Angle: %.2f deg\r\n", angle );

    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.
