Click library

  • Author : Stefan Ilic
  • Date : Jan 2023.
  • Type : I2C/SPI type

Software Support

We provide a library for the 6DOF IMU 18 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 from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for 6DOF IMU 18 Click driver.

Standard key functions :

  • c6dofimu18_cfg_setup Config Object Initialization function.

    void c6dofimu18_cfg_setup ( c6dofimu18_cfg_t *cfg );
  • c6dofimu18_init Initialization function.

    err_t c6dofimu18_init ( c6dofimu18_t *ctx, c6dofimu18_cfg_t *cfg );
  • c6dofimu18_default_cfg Click Default Configuration function.

    err_t c6dofimu18_default_cfg ( c6dofimu18_t *ctx );

Example key functions :

  • c6dofimu18_set_reg_bank 6DOF IMU 18 set register bank function.

    err_t c6dofimu18_set_reg_bank( c6dofimu18_t *ctx, uint8_t bank );
  • c6dofimu18_get_int1_state 6DOF IMU 18 read INT1 pin state function.

    uint8_t c6dofimu18_get_int1_state ( c6dofimu18_t *ctx );
  • c6dofimu18_get_data_from_register 6DOF IMU 18 read data function.

    err_t c6dofimu18_get_data_from_register ( c6dofimu18_t *ctx, float *temperature_data, c6dofimu18_data_t *accel_data, c6dofimu18_data_t *gyro_data, uint32_t *tmst_data );

Example Description

This library contains API for 6DOF IMU 18 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 and accelerator data, and temperature.

The demo application is composed of two sections :

Application Init

Initializes the driver after that resets the device and performs default configuration and reads the device id.


void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    c6dofimu18_cfg_t c6dofimu18_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.
    c6dofimu18_cfg_setup( &c6dofimu18_cfg );
    C6DOFIMU18_MAP_MIKROBUS( c6dofimu18_cfg, MIKROBUS_1 );
    err_t init_flag = c6dofimu18_init( &c6dofimu18, &c6dofimu18_cfg );
    if ( ( I2C_MASTER_ERROR == init_flag ) || ( SPI_MASTER_ERROR == init_flag ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    Delay_ms ( 100 );

    uint8_t id = 0;
    c6dofimu18_reg_read( &c6dofimu18, C6DOFIMU18_BANK0_SEL, C6DOFIMU18_REG_WHO_AM_I, &id, 1);
    log_printf( &logger, " Device ID : 0x%.2X \r\n", ( uint16_t ) id );
    if ( C6DOFIMU18_WHO_AM_I_VALUE != id )
    {
        log_error( &logger, " Communication error." );
        for ( ; ; );
    }
    Delay_ms ( 100 );

    if ( C6DOFIMU18_OK != c6dofimu18_default_cfg ( &c6dofimu18 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

    log_info( &logger, " Application Task " );
}

Application Task

This example demonstrates the use of the 6DOF IMU 18 Click board by measuring and displaying acceleration and gyroscope data for X-axis, Y-axis, and Z-axis as well as temperature in degrees Celsius.

void application_task ( void )
{
    if ( c6dofimu18_get_int1_state( &c6dofimu18) )
    {       
        c6dofimu18_data_t accel_data;
        c6dofimu18_data_t gyro_data;
        float temp_data;
        uint32_t tmst_data;

        c6dofimu18_get_data_from_register( &c6dofimu18, &temp_data, &accel_data, &gyro_data, &tmst_data );
        log_printf( &logger, " TEMP: %.2f \r\n", temp_data );
        log_printf( &logger, " GYRO: x:%d y:%d z:%d \r\n", gyro_data.data_x,gyro_data.data_y,gyro_data.data_z );
        log_printf( &logger, " ACCEL: x:%d y:%d z:%d \r\n", accel_data.data_x,accel_data.data_y,accel_data.data_z );
        log_printf( &logger, "========================== \r\n" );
        Delay_ms ( 1000 );
    }    
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.6DOFIMU18

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. UART terminal is available in all MikroElektronika compilers.
