Library for talking to MCP342x converters using I2C.

Those devices are configured using a single byte and the input voltage is read directly.

Parameters used throughout this library are :

  ::channel
    Up to 4 channels, from 1 to 4, are available depending on the model.

  ::converting?
    When writing the configuration byte, this parameter must be set to true for initiating
    a new measure in :one-shot mode. It does not matter in :continuous mode.
    When reading the input voltage, the converter sets this parameter to false when a new
    conversion is ready.

  ::mode
    In :continuous mode, the converter measures the input voltage constantly whereas in
    :one-shot mode, the measure only happens when the master writes a configuration byte
    with ::converting? set to true.

  ::pga
    Programamble Gain Amplifier.
    #{:x1 :x2 :x4 :x8}

  ::resolution
    Number of bits the input voltage is represented by, depending on the model.
    #{:12-bit :14-bit :16-bit :18-bit}


IO operations will throw in case of failure and are performed using this library :
