	ReadRed
Returns one of the FIFO Red readings from the last update
- UINT	Return

	ReadIR
Returns one of the FIFO IR readings from the last update
- UINT	Return

	Update
Reads the sensor FIFO buffer and stores the readings into local RAM. Returns the number of samples read.
- BYTE	Return

	Initialise
Sets up the I2C bus ready for communications with the sensor IC. Must be called once before calling any of the other component macros. Applies the defauilt settings from the component properties.
- VOID	Return

	Properties
	Connections
	Channel
Channel selection
	SDA
Pin used for SDA (data signal)
	SDA Remap Pin

	SCL
Pin used for SCL (clock signal)
	SCL Remap Pin

	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.
	Baud Select
Baud rate option selector
	Baud Rate
Baud rate to be used
	Sensor Defaults
	Sample Rate
Sets the default sample rate
	Pulse Width
Sets the default pulse width and bit depth of the sensor measurements
	High Resolution Mode
Sets if the module defaults to high or low reolution mode
	IR LED Current
Default current to drive the IR LED
	Red LED Current
Default current to drive the Red LED
	Simulation
	Simulate Comms
Allows the I2C communications to be simulated and interfaced via an API component to real world hardware.
