Library Description

The library covers all the necessary functions to control 6DOF IMU 12 click board. Library performs a standard I2C and SPI interface communication.

Key functions:

  • uint8_t c6dofimu12_generic_read ( uint8_t reg ) - Generic read the byte of data function.
  • void c6dofimu12_burst_write ( uint8_t reg, uint8_t *p_tx_data, uint16_t n_len ) - Generic sequential data write function.
  • void c6dofimu12_get_data ( c6dofimu12_accel_t *accel_data, c6dofimu12_gyro_t *gyro_data ) - Read Accel and Gyro data function.

Examples description

The application is composed of three sections :

  • System Initialization - Initializes I2C and start to write log.
  • Application Initialization - Initialization driver enables - I2C, check communication by read device ID, initializing the device, set default configuration for accelerometer and gyroscope, also write log.
  • Application Task - (code snippet) This is an example which demonstrates the use of 6DOF IMU 12 Click board. Measured and display Accel and Gyro data coordinates values for X-axis, Y-axis and Z-axis. Results are being sent to the Usart Terminal where you can track their changes. All data logs write on USB uart changes for every 1 sec.
void application_task( )
{
    c6dofimu12_get_data ( &accel_data, &gyro_data );

    mikrobus_logWrite( " Accel X :", _LOG_TEXT );
    IntToStr( accel_data.x, log_text );
    mikrobus_logWrite( log_text, _LOG_TEXT );
    mikrobus_logWrite( "  |  ", _LOG_TEXT );
    mikrobus_logWrite( " Gyro X :", _LOG_TEXT );
    IntToStr( gyro_data.x, log_text );
    mikrobus_logWrite( log_text, _LOG_LINE );

    mikrobus_logWrite( " Accel Y :", _LOG_TEXT );
    IntToStr( accel_data.y, log_text );
    mikrobus_logWrite( log_text, _LOG_TEXT );
    mikrobus_logWrite( "  |  ", _LOG_TEXT );
    mikrobus_logWrite( " Gyro Y :", _LOG_TEXT );
    IntToStr( gyro_data.y, log_text );
    mikrobus_logWrite( log_text, _LOG_LINE );

    mikrobus_logWrite( " Accel Z :", _LOG_TEXT );
    IntToStr( accel_data.z, log_text );
    mikrobus_logWrite( log_text, _LOG_TEXT );
    mikrobus_logWrite( "  |  ", _LOG_TEXT );
    mikrobus_logWrite( " Gyro Z :", _LOG_TEXT );
    IntToStr( gyro_data.z, log_text );
    mikrobus_logWrite( log_text, _LOG_LINE );
    mikrobus_logWrite( "-------------------------------------", _LOG_LINE );
    
    Delay_ms( 1000 );
}

  • I2C or SPI
  • UART
  • Conversions

Additional notes and informations

Depending on the development board you are using, you may need USB UART clickUSB 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.
