Macro reference

ControlHeater

ControlHeater
Controls the in-built heater element to speed up sensor recovery time in case of condensation. Humidity and temperature cannot be read while Heater is active. 
- BOOL Active
0 = Off (Sensor Reading Available) / 1 = On (Sensor Reading Disabled) 
- VOID Return


DataAvailable

DataAvailable
Checks to see if new sensor data is available. Returns 0 if no new data is available. Returns 1 if new Temperature data is available. Returns 2 if new Humidity data is available. Returns 3 if new Temp and Humidity data is available. 
- BYTE Return


Initialise

Initialise
Configures the I2C peripheral ready for communications. 
- BYTE Return


ReadHumidityInt

ReadHumidityInt
Samples the humidity from the sensor and returns the relative humidity reading as a integer byte from 0 to 100 
- BYTE Return


ReadHumidityReal

ReadHumidityReal
Samples the humidity from the sensor and returns the relative humidity reading as a float from 0.0 to 100.0. 
- FLOAT Return


ReadRegister

ReadRegister
Reads an 8-bit value from one of the registers onboard the sensor IC. 
- BYTE Address
 
- BYTE Return


ReadTemperatureInt

ReadTemperatureInt
Samples the temperature from the sensor and returns the reading in degrees C as an integer from -40 to 120. 
- INT Return


ReadTemperatureReal

ReadTemperatureReal
Samples the temperature from the sensor and returns the reading in degrees C as a float from -40.0 to 120.0. 
- FLOAT Return


WriteRegister

WriteRegister
Writes a value to a register on the sensor IC. 
- BYTE Address
 
- BYTE Data
 
- VOID Return

SDA

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.
