Constructor Detail

TMP36

public TMP36(AnalogInputDeviceFactoryInterface deviceFactory,
             int gpio,
             float tempOffset)
      throws RuntimeIOException

Parameters:

deviceFactory - Device factory to use to construct the device.

gpio - GPIO on the ADC device.

tempOffset - Compensate for potential temperature reading variations between different TMP36 devices.

Throws:

RuntimeIOException - If an I/O error occurred.
