Downloadable macro reference

	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

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

	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

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

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

	Initialise
Sets up up the communication bus and initialises the accelerometer module. Returns 0 for success and > 0 for fail.
- 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.
	Channel
Channel selection
	Baud Select
Baud rate option selector
	Baud Rate
Baud rate to be used
	SDA
Pin used for SDA (data signal)
	SCL
Pin used for SCL (clock signal)
	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.
	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 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
