5.5.29 comedi_bond -- A driver to ’bond’ (merge) multiple subdevices from multiple devices together as one.
Author: ds
Status: works
This driver allows you to ’bond’ (merge) multiple comedi subdevices
(coming from possibly difference boards and/or drivers) together. For
example, if you had a board with 2 different DIO subdevices, and
another with 1 DIO subdevice, you could ’bond’ them with this driver
so that they look like one big fat DIO subdevice. This makes writing
applications slightly easier as you don’t have to worry about managing
different subdevices in the application -- you just worry about
indexing one linear array of channel id’s.
Right now only DIO subdevices are supported as that’s the personal itch
I am scratching with this driver. If you want to add support for AI and AO
subdevs, go right on ahead and do so!
Commands aren’t supported -- although it would be cool if they were.
Configuration Options:
List of comedi-minors to bond. All subdevices of the same type
within each minor will be concatenated together in the order given here.
