Gyro 3 Click

Gyro 3 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.

• Type : I2C/SPI type

Software Support

Example Description

This example checks if new data is available on all three axes, If yes then reads and logs their values.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Gyro3

Example Key Functions

• gyro3_cfg_setup Config Object Initialization function.

void gyro3_cfg_setup ( gyro3_cfg_t *cfg );

• gyro3_init Initialization function.

err_t gyro3_init ( gyro3_t *ctx, gyro3_cfg_t *cfg );

• gyro3_default_cfg Click Default Configuration function.

void gyro3_default_cfg ( gyro3_t *ctx );

• gyro3_get_temp This function reads value stored in temperature register (26h).

void gyro3_get_temp ( gyro3_t *ctx, uint8_t *temperature_value );

• gyro3_get_fifo_data_level This function reads data level value in FIFO register from FIFO SRC register (2Fh) and stores result in fifo_data_level.

void gyro3_get_fifo_data_level ( gyro3_t *ctx, uint8_t * fifo_data_level );

• gyro3_get_axes This function reads values from XYZ axes registers and converts them to degrees per second value.

void gyro3_get_axes ( gyro3_t *ctx, float *x_axis, float *y_axis, float *z_axis, uint8_t measurement_range );

Application Init

Initialize I2C driver, basic device configuration, I2C interface, LOG interface and GPIO pins.

void application_init ( void )
{
    log_cfg_t log_cfg;
    gyro3_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.

    gyro3_cfg_setup( &cfg );
    GYRO3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    gyro3_init( &gyro3, &cfg );
    gyro3_default_cfg( &gyro3 );

    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}

Application Task

Check if new data is available on all three axes, If yes then read and log their values.

void application_task ( void )
{
    //  Task implementation.

    gyro3_get_status( &gyro3, &status_register );

    if ((status_register & GYRO3_ZYX_NEW_DATA_MASK) == GYRO3_ZYX_NEW_DATA_MASK)
    {

        gyro3_get_axes( &gyro3, &x_axis, &y_axis, &z_axis, GYRO3_MEAS_RANGE_2000 );

        log_printf( &logger, "\r\nx_axis : %.2f %s\t", x_axis, degrees_per_second );
        log_printf( &logger, "y_axis : %.2f %s\t", y_axis, degrees_per_second );
        log_printf( &logger, "z_axis : %.2f %s\r\n", z_axis, degrees_per_second );      
    }
}

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.
