MPU 9DOF Click Board

Software Support

Application Inititialise

Initialization driver enable's - I2C, initialize MPU-9150 XL G & MPU-9150 MAG and start write log.

void application_init ( void )
{
 log_cfg_t log_cfg;
 mpu9dof_cfg_t cfg;

 // Logger initialization.
 log_cfg.level = LOG_LEVEL_DEBUG;
 LOG_MAP_USB_UART( log_cfg );
 log_init( &logger, &log_cfg );
 log_info( &logger, "---- Application Init ----" );

 // Click initialization.
 mpu9dof_cfg_setup( &cfg );
 MPU9DOF_MAP_MIKROBUS( cfg, MIKROBUS_1 );
 mpu9dof_init( &mpu9dof, &cfg );
 Delay_10ms( );
 mpu9dof_default_cfg ( &mpu9dof );
}

Application Task

This is a example which demonstrates the use of the MPU 9DOF Click Board™. Measured accel, gyro and magnetometer coordinates values ( X, Y, Z ) and temperature value in degrees celsius [ �C ] are being sent to the uart where you can track their changes. All data logs on usb uart for aproximetly every 1 sec.

void application_init ( void )
{
    log_cfg_t log_cfg;
    mpu9dof_cfg_t cfg;

    //  Logger initialization.

    log_cfg.level = LOG_LEVEL_DEBUG;
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, "---- Application Init ----" );

    //  Click initialization.

    mpu9dof_cfg_setup( &cfg );
    MPU9DOF_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    mpu9dof_init( &mpu9dof, &cfg );

    Delay_10ms( );
    mpu9dof_default_cfg ( &mpu9dof );
}

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.Mpu9Dof

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.
