iio – Industrial I/O Subsystem

IIO_logo
IIO is a kernel subsystem for analog to digital, digital to analog converters and related hardware. Devices inĀ  this category are:

ADC and DAC
Accelerometers
Gyros
CDC – Capacitance to Digital Converters
Pressure Sensors
Color, Light and Proximity Sensors
Temperature Sensors
Magnetometers
DDS – Direct Digital Synthesis
PLL – Phase Locked Loops
VGA/PGA – Variable/Programmable Gain Amplifiers

IIO kernel subsystem has ben developed since 2009 by Jonathan Cameron. Devices supported or under development in new kernel are listed here: Device List

IIO Subsystem Overview

IIO is organized as two levels:

  • device is the top level of the hierarchy and it represents the acquisition chip.
  • channel is part of device; it represents a single acquisition source of the device.
