|

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.

||||

The real guts of the driver is in ni_mio_common.c, which is included
|
||||
both here and in ni_pcimio.c

ISSUES:

need to deal with external reference for DAC, and other DAC

properties in board properties
|

deal with at-mio-16de-10 revision D to N changes, etc.
