Click library

  • Author : MikroE Team
  • Date : Feb 2020.
  • Type : I2C type

Software Support

We provide a library for the Gyro2 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 Gyro2 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void gyro2_cfg_setup ( gyro2_cfg_t *cfg );

  • Initialization function.

    GYRO2_RETVAL gyro2_init ( gyro2_t ctx, gyro2_cfg_t cfg );

  • Click Default Configuration function.

    void gyro2_default_cfg ( gyro2_t *ctx );

Example key functions :

  • 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.

  • Data that is read is storred the 3 16bit array.

    void gyro2_get_axisraw ( gyro2_t ctx, int16_t axis_data );

  • Function for calculating raw axis data.

    void gyro2_calc_axis ( int16_t *axis_data );

Examples Description

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

The demo application is composed of two sections :

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 );
}

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.Gyro2

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.
