Gyro 9 Click

Gyro 9 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 : Nenad Filipovic
• Date : Aug 2023.
• Type : I2C/SPI type

Software Support

Example Description

This library contains API for Gyro 9 Click driver. The library initializes and defines the I2C and SPI bus drivers to write and read data from registers, as well as the default configuration for reading gyroscope data.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Gyro9

Example Key Functions

• gyro9_cfg_setup Config Object Initialization function.

void gyro9_cfg_setup ( gyro9_cfg_t *cfg );

• gyro9_init Initialization function.

err_t gyro9_init ( gyro9_t *ctx, gyro9_cfg_t *cfg );

• gyro9_default_cfg Click Default Configuration function.

err_t gyro9_default_cfg ( gyro9_t *ctx );

• gyro9_get_gyro_axis Gyro 9 get gyro sensor axes function.

err_t gyro9_get_gyro_axis ( gyro9_t *ctx, gyro9_axis_t *gyro_axis );

• gyro9_get_axis_data Gyro 9 get gyro data function.

err_t gyro9_get_axis_data ( gyro9_t *ctx, gyro9_axis_data_t *gyro_axis );

• gyro9_get_data_ready Gyro 9 get data ready function.

uint8_t gyro9_get_data_ready ( gyro9_t *ctx );

Application Init

The initialization of I2C or SPI module, log UART, and additional pins. After the driver init, the app executes a default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    gyro9_cfg_t gyro9_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.
    gyro9_cfg_setup( &gyro9_cfg );
    GYRO9_MAP_MIKROBUS( gyro9_cfg, MIKROBUS_POSITION_GYRO9 );
    err_t init_flag = gyro9_init( &gyro9, &gyro9_cfg );
    if ( ( I2C_MASTER_ERROR == init_flag ) || ( SPI_MASTER_ERROR == init_flag ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( GYRO9_ERROR == gyro9_default_cfg ( &gyro9 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
    log_printf( &logger, "_________________\r\n" );
    Delay_ms ( 100 );
}

Application Task

This example demonstrates the use of the Gyro 9 Click board™. Measures and displays gyroscope angular rate for X-axis, Y-axis, and Z-axis. Results are being sent to the UART Terminal, where you can track their changes.

void application_task ( void )
{
    gyro9_axis_t gyro_axis;
    if ( gyro9_get_data_ready( &gyro9 ) )
    {
        if ( GYRO9_OK == gyro9_get_gyro_axis( &gyro9, &gyro_axis ) )
        {
            log_printf( &logger, " Gyro X: %.2f pds\r\n", gyro_axis.x );
            log_printf( &logger, " Gyro Y: %.2f pds\r\n", gyro_axis.y );
            log_printf( &logger, " Gyro Z: %.2f pds\r\n", gyro_axis.z );
            log_printf( &logger, "_________________\r\n" );
            Delay_ms ( 1000 );
        }
    }
}

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.
