Click library

  • Author : MikroE Team
  • Date : Jan 2020.
  • Type : I2C type

Software Support

We provide a library for the SmartDof 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for SmartDof Click driver.

Standard key functions :

  • Config Object Initialization function.

    void smartdof_cfg_setup ( smartdof_cfg_t *cfg );

  • Initialization function.

    SMARTDOF_RETVAL smartdof_init ( smartdof_t ctx, smartdof_cfg_t cfg );

  • Click Default Configuration function.

    void smartdof_default_cfg ( smartdof_t *ctx );

Example key functions :

  • 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 )

  • This function receives get feature response report bytes

    uint8_t smartdof_get_feature_response ( smartdof_t ctx, smartdof_sfc_t sfc );

  • This function sends set feature request report to device

    void smartdof_set_feature_command ( smartdof_t ctx, smartdof_sfc_t sfc );

Examples 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.

The demo application is composed of two sections :

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;

    /** 
     * 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.

    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

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

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

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. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
