Gyro 6 click

Gyro 6 Click is a compact add-on board that contains a high-performance gyroscope. This board features the IAM-20380, a 3-axis, digital-output X-, Y-, and Z-axis angular rate sensor (gyroscope) from TDK InvenSense. It has a full-scale programmable range of ±250DPS, ±500DPS, ±1000DPS, and ±2000DPS with a factory-calibrated initial sensitivity and configurable host interface that supports both SPI and I2C serial communication.

Click library

• Author : Stefan Filipovic
• Date : Aug 2021.
• Type : I2C/SPI type

Software Support

We provide a library for the Gyro6 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 from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for Gyro6 Click driver.

Standard key functions :

• gyro6_cfg_setup Config Object Initialization function.

  void gyro6_cfg_setup ( gyro6_cfg_t *cfg );

• gyro6_init Initialization function.

  err_t gyro6_init ( gyro6_t *ctx, gyro6_cfg_t *cfg );

• gyro6_default_cfg Click Default Configuration function.

  err_t gyro6_default_cfg ( gyro6_t *ctx );

Example key functions :

• gyro6_get_axis This function reads the gyroscope values for all three axis.

  err_t gyro6_get_axis ( gyro6_t *ctx, float *x_axis, float *y_axis, float *z_axis );

• gyro6_read_die_temperature This function reads the chip internal temperature.

  err_t gyro6_read_die_temperature ( gyro6_t *ctx, float *temperature );

• gyro6_set_low_power_mode This function enables low power mode and sets the sample rate and average sample data.

  err_t gyro6_set_low_power_mode ( gyro6_t *ctx, uint8_t sample_rate, uint8_t average );

Example Description

This example demonstrates the use of Gyro 6 click board.

The demo application is composed of two sections :

Application Init

Initializes the driver and performs the click default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;      /**< Logger config object. */
    gyro6_cfg_t gyro6_cfg;  /**< Click config object. */

    /** 
     * 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.
    gyro6_cfg_setup( &gyro6_cfg );
    GYRO6_MAP_MIKROBUS( gyro6_cfg, MIKROBUS_1 );
    err_t init_flag  = gyro6_init( &gyro6, &gyro6_cfg );
    if ( ( I2C_MASTER_ERROR == init_flag ) || ( SPI_MASTER_ERROR == init_flag ) )
    {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );
        for ( ; ; );
    }

    if ( GYRO6_ERROR == gyro6_default_cfg ( &gyro6 ) )
    {
        log_error( &logger, " Default Config Error. " );
        log_info( &logger, " Please, run program again... " );
        for ( ; ; );
    }

    log_info( &logger, " Application Task " );
}

Application Task

Waits for the data to be ready, then reads the values of all three axis and displays the results on the USB UART. The data sample rate is set to 10Hz by default, therefore the data is being read approximately every 100ms.

void application_task ( void )
{
    if ( gyro6_get_int_pin ( &gyro6 ) )
    {
        float x_axis_value = 0;
        float y_axis_value = 0;
        float z_axis_value = 0;

        if ( GYRO6_OK == gyro6_get_axis ( &gyro6, &x_axis_value, &y_axis_value, &z_axis_value ) )
        {
            log_printf( &logger, " X : %.2f\r\n", x_axis_value );
            log_printf( &logger, " Y : %.2f\r\n", y_axis_value );
            log_printf( &logger, " Z : %.2f\r\n\n", z_axis_value );
        }
    }
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

• MikroSDK.Board
• MikroSDK.Log
• Click.Gyro6

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. UART terminal is available in all MikroElektronika compilers.
