Gyro 8 Click

Gyro 8 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 : Stefan Filipovic
  • Date : Nov 2022.
  • Type : SPI type

Software Support

Example Description

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

Example Libraries

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Gyro8

Example 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 );
  • 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 );

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;  /**< Logger config object. */
    gyro8_cfg_t gyro8_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.
    gyro8_cfg_setup( &gyro8_cfg );
    GYRO8_MAP_MIKROBUS( gyro8_cfg, MIKROBUS_POSITION_GYRO8 );
    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 );
}

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.
