Hardware Reset

A hardware reset has been provided should the device address be changed to some unknown value. The method of restoring the factory defaults and thus the default device address is as follows:

  1.  Remove power
  2.  Hold the designated pin low or connect two pins together. The actual pins are device dependant and will be referenced in the data sheet for that device.
  3.  Apply power
  4. Remove power
  5.  Remove shorting link

When power is now restored the device will have the default I2C address, normally 0x42 04 0x62.
