	ReadPressureFloat
Reads the pressure as a floating point value in Bars. Resultion sets the return bit value and conversion time. Calls the ReadPressureRaw function and then converts to a meaningful value.
- BYTE	Resolution
Range 0-5
- FLOAT	Return

	Reset
Resets the device
- VOID	Return

	ReadTemperatureFloat
Reads the temperature as a floating point value in °C. Resultion sets the return bit value and conversion time. Calls the ReadTemperatureRaw function and then converts to a meaningful value.
- BYTE	Resolution
Range 0-5
- FLOAT	Return

	ReadPressureRaw
Reads the pressure as a digital 32-bit value. Resultion sets the return bit value and conversion time. 0=0.11mBar / 1=0.062mBar / 2=0.039mBar 3=0.028mBar / 4=0.021mBar / 5=0.016mBar
- BYTE	Resolution
Range 0-5
- ULONG	Return

	ReadTemperatureRaw
Reads the temperature as a digital 32-bit value. Resultion sets the return bit value and conversion time. 0=0.012°C / 1=0.009°C / 2=0.006°C 3=0.004°C / 4=0.003°C / 5=0.002°C
- BYTE	Resolution
Range 0-5
- LONG	Return

	ReadPROM
Reads a single 16-bit value from the PROM calibration data.
- BYTE	Address
Range 0-6
- UINT	Return

	Initialise
Stes up the I2C bus and initialises the termperature sensor ready for use.
- VOID	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.
	Scope Traces
Selects if the component pin connections are automatically generated on the data recorder window or not. Yes: Automatically add the component pins to a group on the data recorder which will reflect the sim data during simultion. No: Do not show the pin signals on the data recorder window.
	Console Data
Selects if the console data is automatically generated or not
	Injector
Specifies the injector component on the panel to interact with to provide comms simulation.
	Connections
	Simulations
	Simulate Comms
Allows the simulation data to come from the panel GUI or relayed via an injector component.
