Inheritance

Constructors

hashCode → int: The hash code for this object.
no setterinherited
i2c → I2C: final
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited

changeI2Caddress(int newI2Caddress) → void: Changes the I2C address of the hat. NOT TESTED!
fromJson(String json) → IsolateAPI: override
getFirmware() → int: Returns the firmware version.
getGrovePowerSupplyVoltage() → int: Returns the supply voltage.
getHandle() → int: override
getId() → int: Returns the internal hardware id of the hat. RPI_HAT_PID (0x4) for a Grove Base Hat RPi, and RPI_ZERO_HAT_PID (0x05) for a Grove Base Hat RPi Zero.
getName() → String: Returns the name of the hat model.
isHatRPiZero() → bool: Returns true for the Pi Zero model, false for the Pi model.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
readADCraw(int channel) → int: Reads the raw data of ADC unit, with 12 bits resolution from the channel 0 - 7 and returns a ADC result in the range 0 - 4095.
readInputVoltage(int channel) → int: Reads the voltage data of ADC unit from the channel 0 - 7 and returns the voltage in mV.
readRatio(int channel) → int: Reads the ratio between channel input voltage and power voltage (most time it's 3.3V). channel 0 - 7, specify the channel to read, returns the ration in 0.1%.
resetHat() → void: Resets the hat. NOT TESTED!
setHandle(int handle) → void: override
toJson() → String: override
toString() → String: A string representation of this object.
