Smart DOF 5 Click

Smart DOF 5 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 : Jul 2024.
• Type : I2C/SPI type

Software Support

Example Description

This example demonstrates the use of Smart DOF 5 Click board by reading and displaying the accelerometer and gyroscope data (X, Y, and Z axis) as well as a temperature measurement in degrees Celsius.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.SmartDOF5

Example Key Functions

• smartdof5_cfg_setup Config Object Initialization function.

void smartdof5_cfg_setup ( smartdof5_cfg_t *cfg );

• smartdof5_init Initialization function.

err_t smartdof5_init ( smartdof5_t *ctx, smartdof5_cfg_t *cfg );

• smartdof5_default_cfg Click Default Configuration function.

err_t smartdof5_default_cfg ( smartdof5_t *ctx );

• smartdof5_get_int_pin This function returns the interrupt 1 pin logic state.

uint8_t smartdof5_get_int_pin ( smartdof5_t *ctx );

• smartdof5_get_data This function reads the accelerometer, gyroscope, and temperature measurement data.

err_t smartdof5_get_data ( smartdof5_t *ctx, smartdof5_data_t *data_out );

• smartdof5_set_accel_fsr This function sets the accel measurement full scale range.

err_t smartdof5_set_accel_fsr ( smartdof5_t *ctx, uint8_t fsr );

Application Init

Initializes the driver and performs the Click default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    smartdof5_cfg_t smartdof5_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.
    smartdof5_cfg_setup( &smartdof5_cfg );
    SMARTDOF5_MAP_MIKROBUS( smartdof5_cfg, MIKROBUS_1 );
    err_t init_flag = smartdof5_init( &smartdof5, &smartdof5_cfg );
    if ( ( I2C_MASTER_ERROR == init_flag ) || ( SPI_MASTER_ERROR == init_flag ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( SMARTDOF5_ERROR == smartdof5_default_cfg ( &smartdof5 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

Waits for a data ready indication and then reads the accelerometer, gyroscope, and temperature measurements. The results are displayed on the USB UART at 12.5 Hz output data rate.

void application_task ( void )
{
    smartdof5_data_t meas_data;
    if ( smartdof5_get_int_pin ( &smartdof5 ) ) 
    {
        if ( SMARTDOF5_OK == smartdof5_get_data ( &smartdof5, &meas_data ) )
        {
            log_printf( &logger, " Accel X: %.3f g\r\n", meas_data.accel.x );
            log_printf( &logger, " Accel Y: %.3f g\r\n", meas_data.accel.y );
            log_printf( &logger, " Accel Z: %.3f g\r\n", meas_data.accel.z );
            log_printf( &logger, " Gyro X: %.1f dps\r\n", meas_data.gyro.x );
            log_printf( &logger, " Gyro Y: %.1f dps\r\n", meas_data.gyro.y );
            log_printf( &logger, " Gyro Z: %.1f dps\r\n", meas_data.gyro.z );
            log_printf( &logger, " Temperature: %.2f degC\r\n\n", meas_data.temperature );
        }
    }
}

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.
