Click library

• Author : Mihajlo Djordjevic
• Date : Dec 2019.
• Type : I2C/SPI type

Software Support

We provide a library for the 6DofImu2 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 6DofImu2 Click driver.

Standard key functions :

• Config Object Initialization function.

  ‍void c6dofimu2_cfg_setup ( c6dofimu2_cfg_t *cfg );

  - Initialization function.

  ‍C6DOFIMU2_RETVAL c6dofimu2_init ( c6dofimu2_t *ctx, c6dofimu2_cfg_t *cfg );

• Click Default Configuration function.

  ‍void c6dofimu2_default_cfg ( c6dofimu2_t *ctx );

Example key functions :

• This function executes default configuration for 6DOF IMU 2 click.

  ‍void c6dofimu2_default_cfg ( c6dofimu2_t *ctx, c6dofimu2_cfg_t *cfg );

  - This function read Accel X-axis, Y-axis and Z-axis.

  ‍void c6dofimu2_read_accel ( c6dofimu2_t *ctx, c6dofimu2_accel_data_t *accel_data );

• This function read Gyro X-axis, Y-axis and Z-axis.

  ‍void c6dofimu2_read_gyro ( c6dofimu2_t *ctx, c6dofimu2_gyro_data_t *gyro_data );

  Examples Description

‍ Example Code presents acceleration and angular rate (gyroscopic) measurement.

The demo application is composed of two sections :

Application Init

‍ Application Init performs Logger and Click initialization.

void application_init ( void )
{
    log_cfg_t log_cfg;
    c6dofimu2_cfg_t cfg;
 
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_printf( &logger, "--------------------------\r\n\n" );
    log_printf( &logger, "     Application  Init\r\n" );
    Delay_ms ( 100 );
 
    //  Click initialization.
 
    c6dofimu2_cfg_setup( &cfg );
    C6DOFIMU2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    c6dofimu2_init( &c6dofimu2, &cfg );
    
    log_printf( &logger, "--------------------------\r\n\n" );
    log_printf( &logger, " --- 6DOF IMU 2 Click ---\r\n" );
    log_printf( &logger, "--------------------------\r\n\n" );
    Delay_ms ( 100 );
    
    c6dofimu2_default_cfg( &c6dofimu2, &cfg );
    Delay_ms ( 100 );
    
    log_printf( &logger, " ---- Initialization ---\r\n" );
    log_printf( &logger, "--------------------------\r\n\n" );
    Delay_ms ( 100 );
}

Application Task

‍ This is an example which demonstrates the usage of 6DOF IMU 2 Click board. It measures accel and gyro coordinates (X,Y,Z) and then the results are being sent to the UART Terminal where you can track their changes for every 1 sec.

void application_task ( void )
{
    c6dofimu2_read_accel( &c6dofimu2, &accel_data );
    Delay_ms ( 100 );
    c6dofimu2_read_gyro( &c6dofimu2, &gyro_data );
    Delay_ms ( 100 );
    
    log_printf( &logger, "    Accel    |    Gyro    \r\n" );
    log_printf( &logger, "--------------------------\r\n" );
    log_printf( &logger, " X = %d  | X = %d \r\n", accel_data.accel_x, gyro_data.gyro_x );
    log_printf( &logger, " Y = %d  | Y = %d \r\n", accel_data.accel_y, gyro_data.gyro_y );
    log_printf( &logger, " Z = %d  | Z = %d \r\n", accel_data.accel_z, gyro_data.gyro_z );
    log_printf( &logger, "--------------------------\r\n" );    
    Delay_ms ( 1000 );
}

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.6DofImu2

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.
