define Package/libiio/description
  libiio is used to interface to the Linux Industrial Input/Output (IIO) Subsystem.
  The Linux IIO subsystem is intended to provide support for devices that in some
  sense are analog to digital or digital to analog converters (ADCs, DACs). This
  includes, but is not limited to ADCs, Accelerometers, Gyros, IMUs, Capacitance
  to Digital Converters (CDCs), Pressure Sensors, Color, Light and Proximity Sensors,
  Temperature Sensors, Magnetometers, DACs, DDS (Direct Digital Synthesis),
  PLLs (Phase Locked Loops), Variable/Programmable Gain Amplifiers (VGA, PGA),
  and RF transceivers. You can use libiio natively on an embedded Linux
  target (local mode), or use libiio to communicate remotely to that same target
  from a host Linux, Windows or MAC over USB or Ethernet or Serial.
