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 0 for success and > 0 for fail.
- BYTE	Return

SimReset1G

	SimReset1G
Resets the simulation to 0.0 on X and Y and 1.0 on Z as if the accelerometer was sitting completely horizontal.
- VOID	Return

SimSetXYZ

	SimSetXYZ
Allows the XYZ slider values to be set via the simulation
- INT	X

- INT	Y

- INT	Z

- VOID	Return

UpdateXYZData

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

Property reference

	Properties
	Bit Depth
The number of binary bits used to store the sensor's X,Y,Z readings.
	Bus Type
The interface used to talk to the accelerometer. I2C - Two Wire Interface SDA / SCL SPI - Four Wire Interface MISO / MOSI / SCK / CS
	Data Rate
Configures how often the sensor collects a new reading. More often = better instant reaction to new events Less often = more stable results
	Scale
The accelerometer readings are scaled based on the maximum amount of G force the sensor can represent. 6G = Bigger gravitational force 2G = Higher resolution
	Int Option
Sets if we use the interrupt pin to check if new data is available
	Power Option
Sets if the sensor is always powered or powered via a microcontroller output pin.
	Connections
	SPI Connections
	Channel
SPI Channel selector
	Prescale
Prescale option selector
	MOSI
SPI Data Out Pin SDO - Also Known as Master Out Slave In (MOSI) when used in Master mode.
	MISO
SPI Data In Pin SDI - Also Known as Master In Slave Out (MISO) when used in Master mode.
	CLK
SPI Clock Pin CLK - The Clock signal is driven by the SPI master.
	CS / SS
Chip Select / Slave Select Pin Master Mode: General purpose output pin used to select the remote SPI device. Slave Mode: Hardware chip select pin input used to select the SPI device.
	Simulation
	Simulation Coms
Yes: Accelerometer data will come from the simulation component sliders. No: Accelerometer data will come from the CAL component - I2C or SPI - API etc
