Smart DOF Click

Smart DOF 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 : MikroE Team
• Date : Jan 2020.
• Type : I2C type

Software Support

Example Description

This Click integrates a triaxial accelerometer, triaxial gyroscope and magnetometer. It can provide very accurate and precise 3D acceleration, magnetic, and angular velocity data, in real-time.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.SmartDof

Example Key Functions

• smartdof_cfg_setup Config Object Initialization function.

  void smartdof_cfg_setup ( smartdof_cfg_t *cfg );

• smartdof_init Initialization function.

  err_t smartdof_init ( smartdof_t *ctx, smartdof_cfg_t *cfg );

• smartdof_default_cfg Click Default Configuration function.

  void smartdof_default_cfg ( smartdof_t *ctx );

• smartdof_receive_packet This function waits for INT pin to go LOW, receives 4 header bytes and than parses header bytes to get data length of entire packet and stores header bytes to header buffer.

  uint8_t smartdof_receive_packet (  smartdof_t *ctx, uint32_t n_cycles_timeout  );

• smartdof_get_feature_response This function receives get feature response report bytes.

  uint8_t smartdof_get_feature_response ( smartdof_t *ctx, smartdof_sfc_t *sfc );

• smartdof_set_feature_command This function sends set feature request report to device.

  void smartdof_set_feature_command ( smartdof_t *ctx, smartdof_sfc_t *sfc );

Application Init

Initializes I2C driver and Smart DOF device

void application_init ( void )
{
    uint8_t p;
    log_cfg_t log_cfg;
    smartdof_cfg_t cfg;

    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, "---- Application Init ----" );
 
    //  Click initialization.
 
    smartdof_cfg_setup( &cfg );
    SMARTDOF_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    smartdof_init( &smartdof, &cfg );
 
    if ( smartdof_default_cfg ( &smartdof ) !=0 )
    {
        log_info( &logger, "Error during default configuration" );
    }
}

Application Task

Executes one of 'smartdof_xxx_task()' additional functions

void application_task ( void )
{
    accelerometer_task( &smartdof, &smartdof_sfc );
}

Note

Additional Functions :
- accelerometer_task() - initializes accelerometer reports in 100000 micro second intervals, receives, parses and logs report data
- gyroscope_task() - initializes gyroscope calibrated reports in 100000 micro second intervals, receives, parses and logs report data
- magnetometer_task() - initializes magnetometer calibrated reports in 100000 micro second intervals, receives, parses and logs report data

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.
