need a separate driver as a wrapper. For those that do work, the
I/O port base address can be found in the output of 'lspci -v'.

The PC36AT ISA board and PCI236 PCI board have a single 8255 appearing
as subdevice 0.
Subdevice 1 pretends to be a digital input device, but it always returns
0 when read. However, if you run a command with scan_begin_src=TRIG_EXT,
a rising edge on port C bit 7 acts as an external trigger, which can be
used to wake up tasks. This is like the comedi_parport device, but the
only way to physically disable the interrupt on the PC36AT is to remove
the IRQ jumper. If no interrupt is connected, then subdevice 1 is
unused.

Driver: cb_pcimdda.o
Description: A driver for this relatively new and uniquely designed board
Devices: [Computer Boards] PCIM-DDA06-16 (pcimdda06-16)
Author: Calin Culianu <calin@ajvar.org>
Updated: Thu, 20 Jun 2002 16:19:41 -0500
Status: works
All features of the PCIM-DDA06-16 board are supported. This board
has 6 16-bit AO channels, and the usual 8255 DIO setup. (24 channels,
configurable in banks of 8 and 4, etc.). This board does not support commands.
The board has a peculiar way of specifying AO gain/range settings -- You have
1 jumper bank on the card, which either makes all 6 AO channels either
5 Volt unipolar, 5V bipolar, 10 Volt unipolar or 10V bipolar.
Since there is absolutely _no_ way to tell in software how this jumper is set
(well, at least according to the rather thin spec. from Measurement Computing
that comes with the board), the driver assumes the jumper is at its factory
default setting of +/-5V.
Also of note is the fact that this board features another jumper, whose
state is also completely invisible to software. It toggles two possible AO
output modes on the board:
- Update Mode: Writing to an AO channel instantaneously updates the actual
signal output by the DAC on the board (this is the factory default).
- Simultaneous XFER Mode: Writing to an AO channel has no effect until
you read from any one of the AO channels. This is useful for loading
all 6 AO values, and then reading from any one of the AO channels on the
device to instantly update all 6 AO values in unison. Useful for some
control apps, I would assume? If your jumper is in this setting, then you
need to issue your comedi_data_write()s to load all the values you want,
then issue one comedi_data_read() on any channel on the AO subdevice
to initiate the simultaneous XFER.
