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


Property reference

Properties
Device Settings
Device Address
 
Measurement Rate
 
Oversample Rate
 
Operational Mode
 
Connections
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.  
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.
