CollectXYZData

CollectXYZData
Collect the data from the local XYZ buffers. The Axis parameter specifies the Axis to be read. 0 / 'x' / 'X' - X axis 1 / 'y' / 'Y' - Y axis 2 / 'z' / 'Z' - Z axis 
- BYTE Axis
Axis parameter 
- INT Return


Initialise

Initialise
Sets up up the communication bus and initialises the accelerometer module. Returns 0 for success and > 0 for fail. 
- BYTE Return


ReadCompassCalibration

ReadCompassCalibration
Allows one of the three compass calibration values to be read back. The Axis parameter specifies the Axis to be read. 0 / 'x' / 'X' - X axis 1 / 'y' / 'Y' - Y axis 2 / 'z' / 'Z' - Z axis 
- BYTE Axis
Axis Parameter 
- BYTE Return


ReadTemperature

ReadTemperature
Reads the temperature from the sensor and returns the value as an integer. 
- INT Return


Read_Bearing

Read_Bearing
Reads the current sensor compass bearing based on degrees CW from magnetic north. Returns 0-359 where 0 = North, 90 = East, 180 = South, 270 = West Requires the ArcTan floating point function to be available to work correctly. Supported on AVR, 16-bit

Properties
Connections
AD0 Pin
Determines the LSB of the I2C device address to allow up to two sensors to work together. 
Channel
Channel selection 
Baud Select
Baud rate option selector 
Baud Rate
Baud rate to be used 
Stop Delay
On older microcontroller devices there is a potential for the I2C hardware channel to lock up if there is not a 10ms delay between an I2C stop event and the next I2C start event. Most modern microcontrollers will not have a problem so this property can be disabled to speed up the I2C communications.  
SDA
Pin used for SDA (data signal) 
SCL
Pin used for SCL (clock signal) 
Sensor Properties
Accel Scale
Sets the output range of the accelerometer sensor 
Accel Data Rate
Sets the accelerometer data rate and bandwidth 
Gyro Scale
Sets the output scale of the gyro, measured in degrees per second
