Driver: ni_pcimio.o
Description: National Instruments PCI-MIO-E series (all boards)
Author: ds, John Hallen, Frank Mori Hess, Rolf Mueller, Herbert Peremans,
  Herman Bruyninckx
Status: works
Devices: [National Instruments] PCI-MIO-16XE-50 (ni_pcimio),
  PCI-MIO-16XE-10, PXI-6030E, PCI-MIO-16E-1, PCI-MIO-16E-4, PCI-6040E,
  PXI-6040E, PCI-6031E, PCI-6032E, PCI-6033E, PCI-6071E, PCI-6023E,
  PCI-6024E, PCI-6025E, PXI-6025E, PCI-6034E, PCI-6035E, PCI-6052E,
  PCI-6110, PCI-6111, PCI-6711, PCI-6713, PXI-6071E, PXI-6070E,
  PXI-6052E, PCI-6036E, PCI-6731, PCI-6733
Updated: Sat, 16 Mar 2002 17:34:48 -0800

These boards are almost identical to the AT-MIO E series, except that
they use the PCI bus instead of ISA (i.e., AT).  See the notes for
the ni_atmio.o driver for additional information about these boards.

Autocalibration is supported on many of the devices, using the
calibration utility in Comedilib.

By default, the driver uses DMA to transfer analog input data to
memory.  When DMA is enabled, not all triggering features are
supported.

Streaming analog output is not supported on PCI-671x and PCI-673x.

PCI IDs are not known for PCI-6731 and PCI-6733.  Digital I/O may not
work on 673x.

Information (number of channels, bits, etc.) for some devices may be
incorrect.  Please check this and submit a bug if there are problems
for your device.

Bugs:
 - When DMA is enabled, COMEDI_EV_SCAN_END and COMEDI_EV_CONVERT do
   not work correctly.
 - There are reported problems with the 67xx boards.

	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.

	need to add other CALDAC type

	need to slow down DAC loading.  I don't trust NI's claim that
	two writes to the PCI bus slows IO enough.  I would prefer to
	use comedi_udelay().  Timing specs: (clock)
		AD8522		30ns
		DAC8043		120ns
		DAC8800		60ns
		MB88341		?
