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 |

|
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. | |
