Initialise

Initialise
Stes up the I2C bus and initialises the termperature sensor ready for use. 
- VOID Return


ReadPROM

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


ReadPressureFloat

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


ReadPressureRaw

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


ReadTemperatureFloat

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


ReadTemperatureRaw

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

Properties
I2C Properties
Channel
Channel selection 
SDA
Pin used for SDA (data signal) 
SCL
Pin used for SCL (clock signal) 
Baud Select
Baud rate option selector 
Baud Rate
Baud rate to be used 
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.  
Simulation
Simulate Comms
Allows the simulation data to come from the panel GUI or relayed via an injector component.
