Macro reference

ControlHeater

Fc9-comp-macro.png 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. 
Fc9-bool-icon.png - BOOL Active
0 = Off (Sensor Reading Available) / 1 = On (Sensor Reading Disabled) 
Fc9-void-icon.png - VOID Return


DataAvailable

Fc9-comp-macro.png 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. 
Fc9-u8-icon.png - BYTE Return


Initialise

Fc9-comp-macro.png Initialise
Configures the I2C peripheral ready for communications. 
Fc9-u8-icon.png - BYTE Return


ReadHumidityInt

Fc9-comp-macro.png ReadHumidityInt
Samples the humidity from the sensor and returns the relative humidity reading as a integer byte from 0 to 100 
Fc9-u8-icon.png - BYTE Return


ReadHumidityReal

Fc9-comp-macro.png ReadHumidityReal
Samples the humidity from the sensor and returns the relative humidity reading as a float from 0.0 to 100.0. 
Fc9-f32-icon.png - FLOAT Return


ReadRegister

Fc9-comp-macro.png ReadRegister
Reads an 8-bit value from one of the registers onboard the sensor IC. 
Fc9-u8-icon.png - BYTE Address
 
Fc9-u8-icon.png - BYTE Return


ReadTemperatureInt

Fc9-comp-macro.png ReadTemperatureInt
Samples the temperature from the sensor and returns the reading in degrees C as an integer from -40 to 120. 
Fc9-s16-icon.png - INT Return


ReadTemperatureReal

Fc9-comp-macro.png ReadTemperatureReal
Samples the temperature from the sensor and returns the reading in degrees C as a float from -40.0 to 120.0. 
Fc9-f32-icon.png - FLOAT Return


WriteRegister

Fc9-comp-macro.png WriteRegister
Writes a value to a register on the sensor IC. 
Fc9-u8-icon.png - BYTE Address
 
Fc9-u8-icon.png - BYTE Data
 
Fc9-void-icon.png - VOID Return

Fc9-type-5-icon.png SDA
Pin used for SDA (data signal) 
Fc9-type-5-icon.png SCL
Pin used for SCL (clock signal) 
Fc9-type-7-icon.png 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.
