Library Description

Library contains function for getting INT pin state Library contains function for setting CS pin state Library contains function for getting register values Library contains function for setting register values Library contains function for device initialization Library contains function for getting temperature value Library contains function for getting axes values Library contains function for software reset Library contains functions for setting power mode and full scale range

Key functions:

• uint8_t gyro5_initialize( void ) - initializes the device.
• uint8_t gyro5_get_temperature( float * temperature ) - reads temperature measurement registers and converts raw temperature data to get die temperature in [deg C].
• uint8_t gyro5_get_axes( float * x_axis, float * y_axis, float * z_axis ) - reads axes measurement registers and converts raw axes measurement data to get gyroscope data in [deg/s].

Examples description

The application is composed of three sections :

• System Initialization - Initializes GPIO pins, I2C and LOG modules.
• Application Initialization - Initializes I2C driver and the device.
• Application Task - Checks data ready INT, gets temperature and axes data and LOGs those values.

void applicationTask( )
{
    data_ready_flag = gyro5_interrupt_status( _GYRO5_INT_DATA_RDY );
    
    if (data_ready_flag == 1)
    {
        gyro5_get_temperature( &temperature_value );
        gyro5_get_axes( &x_axis_value, &y_axis_value, &z_axis_value );

        mikrobus_logWrite( " ", _LOG_LINE );

        FloatToStr( x_axis_value, text );
        gyro5_floatCut( );
        mikrobus_logWrite( "> X axis = ", _LOG_TEXT );
        mikrobus_logWrite( text, _LOG_TEXT );
        mikrobus_logWrite( degrees_per_second, _LOG_LINE );

        FloatToStr( y_axis_value, text );
        gyro5_floatCut( );
        mikrobus_logWrite( "> Y axis = ", _LOG_TEXT );
        mikrobus_logWrite( text, _LOG_TEXT );
        mikrobus_logWrite( degrees_per_second, _LOG_LINE );

        FloatToStr( z_axis_value, text );
        gyro5_floatCut( );
        mikrobus_logWrite( "> Z axis = ", _LOG_TEXT );
        mikrobus_logWrite( text, _LOG_TEXT );
        mikrobus_logWrite( degrees_per_second, _LOG_LINE );

        FloatToStr( temperature_value, text );
        gyro5_floatCut( );
        mikrobus_logWrite( "> Temperature = ", _LOG_TEXT );
        mikrobus_logWrite( text, _LOG_TEXT );
        mikrobus_logWrite( degrees_celsius, _LOG_LINE );
    }
    Delay_ms(300);
}

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.
