Gyro 2 Click

Gyro 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 : Feb 2020.
• Type : I2C type

Software Support

Example Description

This application enables usage of 3 angular movement and velocity sensor.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Gyro2

Example Key Functions

• gyro2_cfg_setup Config Object Initialization function.

void gyro2_cfg_setup ( gyro2_cfg_t *cfg );

• gyro2_init Initialization function.

err_t gyro2_init ( gyro2_t *ctx, gyro2_cfg_t *cfg );

• gyro2_default_cfg Click Default Configuration function.

void gyro2_default_cfg ( gyro2_t *ctx );

• gyro2_get_id Function will return the ID from the ID register.

uint8_t gyro2_get_id ( gyro2_t *ctx );

• Function will read the X, Y and Z axis registers.
• gyro2_get_axisraw Data that is read is storred the 3 16bit array.

void gyro2_get_axisraw ( gyro2_t *ctx, int16_t *axis_data );

• gyro2_calc_axis Function for calculating raw axis data.

void gyro2_calc_axis ( int16_t *axis_data );

Application Init

Initialize the communication interface and configure the Click board.

void application_init ( void )
{
    log_cfg_t log_cfg;
    gyro2_cfg_t cfg;
    uint8_t temp;

    /** 
     * 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.

    gyro2_cfg_setup( &cfg );
    GYRO2_MAP_MIKROBUS( cfg, MIKROBUS_1 );

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

    gyro2_init( &gyro2, &cfg );

    temp = gyro2_default_cfg( &gyro2 );

    if ( temp == 1 )
    {
        log_printf( &logger, "Gyro 2 present\r\n" );
    }
    else if ( temp == 2 )
    {
        log_printf( &logger, "Error\r\n" );
    }
    Delay_ms ( 100 );
}

Application Task

Read the x,y,z and temperature data from the Click board and display the resoults on the serial port.

void application_task ( void )
{
    //  Task implementation.

    int16_t axis_data[ 3 ];
    uint8_t temperature;

    gyro2_get_axisraw( &gyro2, axis_data );
    gyro2_calc_axis( axis_data );

    log_printf( &logger, "x: %d \r\ny: %d \r\nz: %d \r\n", axis_data[ 0 ], axis_data[ 1 ], axis_data[ 2 ] );

    temperature = gyro2_read_temperature( &gyro2 );

    log_printf( &logger, "Temperature: %d C\r\n ++ \r\n", temperature );

    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.
