Gyro 5 click

Gyro 5 Click is a three-axis gyroscope Click board™ that can sense motion over three perpendicular axes. It is equipped with the ITG-3701, a three-axis digital gyroscope.

Click library

• Author : Luka Filipovic
• Date : Nov 2019.
• Type : I2C/SPI type

Software Support

We provide a library for the Gyro5 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for Gyro5 Click driver.

Standard key functions :

• Config Object Initialization function.

  void gyro5_cfg_setup ( gyro5_cfg_t *cfg );

• Initialization function.

  GYRO5_RETVAL gyro5_init ( gyro5_t ctx, gyro5_cfg_t cfg );

• Click Default Configuration function.

  void gyro5_default_cfg ( gyro5_t *ctx );

Example key functions :

• Getting gyroscope axes values

  void gyro5_get_axes ( gyro5_t ctx, float x_axis, float y_axis, float z_axis );

• Getting temperature value

  void gyro5_get_temperature ( gyro5_t ctx, float temperature );

• Click Default Configuration function.

  void gyro5_default_cfg ( gyro5_t *ctx );

Examples Description

This application shows temperature and gyroscope axes values

The demo application is composed of two sections :

Application Init

Initializes GPIO pins, I2C and LOG modules.

void application_init ( void )
{
    log_cfg_t log_cfg;
    gyro5_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.

    gyro5_cfg_setup( &cfg );
    GYRO5_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    gyro5_init( &gyro5, &cfg );
    gyro5_default_cfg ( &gyro5 );
    Delay_ms ( 1000 );

    log_printf( &logger, "      Gyro 5 Click\r\n" );
    log_printf( &logger, "-----------------------\r\n" );
}

Application Task

Checks data ready INT, gets temperature and axes data and LOGs those values

void application_task ( void )
{
    //  Task implementation.

    data_ready_flag = gyro5_int_status( &gyro5, GYRO5_INT_DATA_RDY );

    if ( data_ready_flag == GYRO5_STATUS_INT_DATA_RDY )
    {
        gyro5_get_temperature( &gyro5, &temperature_value );
        Delay_ms ( 10 );
        gyro5_get_axes(  &gyro5, &x_axis_value, &y_axis_value, &z_axis_value );
        Delay_ms ( 10 );
        log_printf( &logger, " Temperature = %.2f C\r\n", temperature_value );
        log_printf( &logger, " X axis = %.2f deg/s\r\n", x_axis_value );
        log_printf( &logger, " Y axis = %.2f deg/s\r\n", y_axis_value );
        log_printf( &logger, " Z axis = %.2f deg/s\r\n", z_axis_value );
        log_printf( &logger, "------------------------\r\n" );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
    }
}  

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

• MikroSDK.Board
• MikroSDK.Log
• Click.Gyro5

Additional notes and informations

Depending on the development board you are using, you may need USB UART click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
