Driver: ni_atmio
Description: National Instruments AT-MIO-E series
Author: ds
Devices: [National Instruments] AT-MIO-16E-1 (ni_atmio),
  AT-MIO-16E-2, AT-MIO-16E-10, AT-MIO-16DE-10, AT-MIO-64E-3,
  AT-MIO-16XE-50, AT-MIO-16XE-10, AT-AI-16XE-10
Status: works
Updated: Thu May  1 20:03:02 CDT 2003

The driver has 2.6 kernel isapnp support, and
will automatically probe for a supported board if the
I/O base is left unspecified with comedi_config.
However, many of
the isapnp id numbers are unknown.  If your board is not
recognized, please send the output of 'cat /proc/isapnp'
(you may need to modprobe the isa-pnp module for
/proc/isapnp to exist) so the
id numbers for your board can be added to the driver.

Otherwise, you can use the isapnptools package to configure
your board.  Use isapnp to
configure the I/O base and IRQ for the board, and then pass
the same values as
parameters in comedi_config.  A sample isapnp.conf file is included
in the etc/ directory of Comedilib.

Comedilib includes a utility to autocalibrate these boards.  The
boards seem to boot into a state where the all calibration DACs
are at one extreme of their range, thus the default calibration
is terrible.  Calibration at boot is strongly encouraged.

To use the extended digital I/O on some of the boards, enable the
8255 driver when configuring the Comedi source tree.

External triggering is supported for some events.  The channel index
(scan_begin_arg, etc.) maps to PFI0 - PFI9.

Some of the more esoteric triggering possibilities of these boards
are not supported.
