GMR Angle Click

GMR Angle 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 is an example which demonstrates the use of GMR Angle Click board.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.GmrAngle

Example Key Functions

• gmrangle_cfg_setup Config Object Initialization function.

void gmrangle_cfg_setup ( gmrangle_cfg_t *cfg ); 

• gmrangle_init Initialization function.

err_t gmrangle_init ( gmrangle_t *ctx, gmrangle_cfg_t *cfg );

• gmrangle_read_data Generic read 16-bit data function.

uint16_t gmrangle_read_data ( gmrangle_t *ctx, uint8_t reg );

• gmrangle_write_data Generic write 16-bit data function.

void gmrangle_write_data ( gmrangle_t *ctx, uint8_t reg, uint16_t tx_data );

• gmrangle_calculate_angle Calculate angle function.

float gmrangle_calculate_angle ( gmrangle_t *ctx );

Application Init

Initializes GPIO pins, SPI and LOG modules.

void application_init ( void )
{
    log_cfg_t log_cfg;
    gmrangle_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.
    gmrangle_cfg_setup( &cfg );
    GMRANGLE_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    gmrangle_init( &gmrangle, &cfg );
    
    GMRANGLE_SET_DATA_SAMPLE_EDGE; 
    
    log_printf( &logger, "---------------------\r\n" );
    log_printf( &logger, "   GMR Angle Click\r\n" );
    log_printf( &logger, "---------------------\r\n" );
    log_printf( &logger, "        Start\r\n" );
    log_printf( &logger, "---------------------\r\n" );
    Delay_ms ( 100 );
}

Application Task

Display angle value in degrees. Results are being sent to the Usart Terminal where you can track their changes. All data logs write on USB uart changes for every 300 msec.

void application_task ( void )
{
    angle = gmrangle_calculate_angle( &gmrangle );
    log_printf( &logger, " Angle is %.1f\r\n", angle );
    Delay_ms ( 300 );
}

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.
