The industrial I/O subsystem provides a unified framework for

drivers for many different types of embedded sensors using a
|

number of different physical interfaces (i2c, spi, etc).

Provides IIO core support for triggers. Currently these
|
|
are used to initialize capture of samples to push into
|
|
buffers. The triggers are effectively a 'capture
