Gyro 8 click

‍Gyro 8 Click is a compact add-on board that contains a high-performance gyroscope. This board features Murata's SCR2100-D08, a high-performance single-axis angular rate sensor (gyroscope). Based on Murata's proven capacitive 3D-MEMS technology, the SCR2100-D08 is characterized by high stability and reliability, providing immensely stable output over a wide range of temperatures, humidity, and vibration. This high-resolution gyroscope supports ±125°/s X-axis angular rate measurement range, extensive self-diagnostic features, an SPI serial interface, and low power consumption.

Click library

• Author : Stefan Filipovic
• Date : Nov 2022.
• Type : SPI type

Software Support

We provide a library for the Gyro 8 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 Gyro 8 Click driver.

Standard key functions :

• gyro8_cfg_setup Config Object Initialization function.

  void gyro8_cfg_setup ( gyro8_cfg_t *cfg );

• gyro8_init Initialization function.

  err_t gyro8_init ( gyro8_t *ctx, gyro8_cfg_t *cfg );

• gyro8_default_cfg Click Default Configuration function.

  err_t gyro8_default_cfg ( gyro8_t *ctx );

Example key functions :

• gyro8_read_serial_id This function reads the serial ID which is laser marked on the sensor lid.

  err_t gyro8_read_serial_id ( gyro8_t *ctx, uint32_t *serial_id );

• gyro8_read_temperature This function reads the temperature measurement in Celsius.

  err_t gyro8_read_temperature ( gyro8_t *ctx, float *temperature );

• gyro8_read_angular_rate This function reads the angular rate of X-axis in dps.

  err_t gyro8_read_angular_rate ( gyro8_t *ctx, float *rate );

Example Description

‍This example demonstrates the use of Gyro 8 click board by reading and displaying the temperature and angular rate measurements.

The demo application is composed of two sections :

Application Init

‍Initializes the driver and the click board, and reads the serial ID number which is marked on the sensor lid.

void application_init ( void )
{
    log_cfg_t log_cfg;  
    gyro8_cfg_t gyro8_cfg;  
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );
 
    // Click initialization.
    gyro8_cfg_setup( &gyro8_cfg );
    GYRO8_MAP_MIKROBUS( gyro8_cfg, MIKROBUS_1 );
    if ( SPI_MASTER_ERROR == gyro8_init( &gyro8, &gyro8_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( GYRO8_ERROR == gyro8_default_cfg ( &gyro8 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    
    uint32_t serial_id;
    if ( GYRO8_OK == gyro8_read_serial_id ( &gyro8, &serial_id ) )
    {
        log_printf ( &logger, " Serial ID: %lu\r\n", serial_id );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

‍Reads the temperature and angular rate measurements every 100ms and displays the results on the USB UART.

void application_task ( void )
{
    float temperature, angular_rate;
    if ( GYRO8_OK == gyro8_read_temperature ( &gyro8, &temperature ) )
    {
        log_printf ( &logger, " Temperature: %.2f degC\r\n", temperature );
    }
    if ( GYRO8_OK == gyro8_read_angular_rate ( &gyro8, &angular_rate ) )
    {
        log_printf ( &logger, " Angular rate: %.2f dps\r\n\n", angular_rate );
    }
    Delay_ms ( 100 );
}

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.Gyro8

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.
