Properties​

DefaultI2cAddress​

The default I2C address for the peripheral

View Source​
Declaration
public byte DefaultI2cAddress { get; }

IsDevicePowered​

Set by the sensor, to tell us it has power.

View Source​
Declaration
public bool IsDevicePowered { get; set; }

IsDeviceBusy​

Set by the sensor, to tell us it's busy.

View Source​
Declaration
public bool IsDeviceBusy { get; set; }

HasMemoryIntegrityFailed​

Set by the sensor, to tell us whether or not there's an issue with its own memory.

View Source​
Declaration
public bool HasMemoryIntegrityFailed { get; set; }

RawPsiMeasurement​

Returns the current raw pressure value in pounds per square inch (PSI)

View Source​
Declaration
public Pressure? RawPsiMeasurement { get; }

Pressure​

Returns the current pressure reading

View Source​
Declaration
public Pressure? Pressure { get; }

InternalMathSaturated​

Indicates the sensor has reached its pressure limit.

View Source​
Declaration
public bool InternalMathSaturated { get; set; }

Methods​

RaiseEventsAndNotify(IChangeResult<(Pressure? Pressure, Pressure? RawPsiMeasurement)>)​

Notify subscribers of PressureUpdated event handler

View Source​
Declaration
protected override void RaiseEventsAndNotify(IChangeResult<(Pressure? Pressure, Pressure? RawPsiMeasurement)> changeResult)
Parameters​
TypeName
Meadow.IChangeResult<System.ValueTuple<System.Nullable<Meadow.Units.Pressure>,System.Nullable<Meadow.Units.Pressure>>>changeResult

ReadSensor()​

Convenience method to get the current Pressure. For frequent reads, use StartSampling() and StopSampling() in conjunction with the SampleBuffer.

View Source​
Declaration
protected override Task<(Pressure? Pressure, Pressure? RawPsiMeasurement)> ReadSensor()
Returns​

System.Threading.Tasks.Task<System.ValueTuple<System.Nullable<Meadow.Units.Pressure>,System.Nullable<Meadow.Units.Pressure>>>
