Macro reference

CollectXYZData

	CollectXYZData
Collect the data from the local accelerometer 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
- INT	Return

Initialise

	Initialise
Sets up up the communication bus and initialises the accelerometer module. Returns 1 for success and 0 for fail.
- BYTE	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
- BYTE	NumSamples
The number of readings to base the bearing on
- UINT	Return

Read_Register

	Read_Register
Reads a value from a register on the accelerometer.
- BYTE	Reg
- BYTE	Return

SimReset1G

	SimReset1G
- VOID	Return

SimSetAccelerometer

	SimSetAccelerometer
Allows the XYZ slider values to be set via the simulation
- INT	X
- INT	Y
- INT	Z
- VOID	Return

SimSetCompass

	SimSetCompass
Allows the XYZ slider values to be set via the simulation
- INT	X
- INT	Y
- INT	Z
- VOID	Return

UpdateAccelerometerData

	UpdateAccelerometerData
Reads from the accelerometer and updates the local XYZ variables. Returns 1 for new data and 0 for no new data
- BYTE	Return

UpdateCompassData

	UpdateCompassData
Reads from the compass and updates the local XYZ variables. Returns 1 for new data and 0 for no new data
- BYTE	Return

Write_Register

	Write_Register
Writes a data value to a specific register on the accelerometer
- BYTE	Reg
- BYTE	Data
- BYTE	Return

	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)
	Simulation
	Simulate Comms
Yes: Accelerometer data will come from the simulation component sliders. No: Accelerometer data will come from the I2C CAL component - Injector etc
