Macro reference

ConfigurePressure

	ConfigurePressure
Configures the pressure sensor sample rate and over sampling count
- BYTE	Rate
Range: 0-7, 0=1Hz, 1=2Hz, 2=4Hz etc
- BYTE	Oversample
Range: 0-7, 0=1Samples, 1=2Samples, 2=4Samples etc
- VOID	Return

ConfigureTemperature

	ConfigureTemperature
Configures the temperature sensor sample rate and over sampling count
- BYTE	Rate
Range: 0-7, 0=1Hz, 1=2Hz, 2=4Hz etc
- BYTE	Oversample
Range: 0-7, 0=1Samples, 1=2Samples, 2=4Samples etc
- VOID	Return

Initialise

	Initialise
Starts up the I2C ready to communicate with the sensor. Sets the selected rates and operational mode. Returns 1 if the sensor has been found and initialised.
- BOOL	Return

ReadAltitude

	ReadAltitude
Reads the pressure measurement from the last SampleSensor macro and converts the pressure reading into an altitude reading.
- FLOAT	Return

ReadPressure

	ReadPressure
Reads the pressure measurement from the last SampleSensor macro
- FLOAT	Return

ReadRegister

	ReadRegister
Reads a byte from a register
- BYTE	Address
- BYTE	Return

ReadTemperature

	ReadTemperature
Reads the temperature measurement from the last SampleSensor macro
- FLOAT	Return

SampleSensor

	SampleSensor
Checks to see if new data is available for temperature or pressure and collects it. Returns 0 if no new data is available Returns 1 for pressure, 2 for temperature and 3 for both.
- BYTE	Return

SetMode

	SetMode
Sets the operational mode of the sensor to be continous or one shot
- BYTE	Mode
- VOID	Return

WriteRegister

	WriteRegister
Writes a byte to a register
- BYTE	Address
- BYTE	Data
- 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.
	Simulation
	Simulate Comms
No: Provides simulation using the panel component sliders. Yes: Communicates via an API Slave device to real world hardware, shows the results using the panel component sliders.
