The classic in digital I/O.  The 8255 appears in Comedi as a single
digital I/O subdevice with 24 channels.  The channel 0 corresponds
to the 8255's port A, bit 0; channel 23 corresponds to port C, bit
7.  Direction configuration is done in blocks, with channels 0-7,
8-15, 16-19, and 20-23 making up the 4 blocks.  The only 8255 mode
supported is mode 0.

You should enable compilation this driver if you plan to use a board
that has an 8255 chip.  For multifunction boards, the main driver will
configure the 8255 subdevice automatically.

This driver also works independently with ISA and PCI cards that
directly map the 8255 registers to I/O ports, including cards with
multiple 8255 chips.  To configure the driver for such a card, the
option list should be a list of the I/O port bases for each of the
8255 chips.  For example,

  comedi_config /dev/comedi0 8255 0x200,0x204,0x208,0x20c

Note that most PCI 8255 boards do NOT work with this driver, and
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'.

This driver supports AI, AO, DI and DO subdevices.
AI subdevice supports cmd and insn interface,
other subdevices support only insn interface.
For AI:
- If cmd->scan_begin_src=TRIG_EXT then trigger input is TGIN (pin 46).
- If cmd->convert_src=TRIG_EXT then trigger input is EXTTRG (pin 44).
- If cmd->start_src/stop_src=TRIG_EXT then trigger input is TGIN (pin 46).
- It is not neccessary to have cmd.scan_end_arg=cmd.chanlist_len but
  cmd.scan_end_arg modulo cmd.chanlist_len must by 0.
- If return value of cmdtest is 5 then you've bad channel list
  (it isn't possible mixture S.E. and DIFF inputs or bipolar and unipolar
  ranges).

There are some hardware limitations:
a) You cann't use mixture of unipolar/bipoar ranges or differencial/single
   ended inputs.
b) DMA transfers must have the length aligned to two samples (32 bit),
   so there is some problems if cmd->chanlist_len is odd. This driver tries
   bypass this with adding one sample to the end of the every scan and discard
   it on output but this cann't be used if cmd->scan_begin_src=TRIG_FOLLOW
   and is used flag TRIG_WAKE_EOS, then driver switch to interrupt driven mode
   with interrupt after every sample.
c) If isn't used DMA then you can use only mode where
   cmd->scan_begin_src=TRIG_FOLLOW.

Subdevice 0 is 8-channel AO, 16-bit, range +/- 10 V.

Subdevice 1 is 16-channel DIO.  The channels are configurable as input or
output in 2 groups (0 to 7, 8 to 15).  Configuring any channel implicitly
configures all channels in the same group.


1. Add the two milliamp ranges to the AO subdevice (0 to 20 mA, 4 to 20 mA).
2. Read the initial ranges and values of the AO subdevice at start-up instead
   of reinitializing them.
3. Implement calibration.

Each PPI is a 8255 chip providing 24 DIO channels.  The DIO channels
are configurable as inputs or outputs in four groups:

  Port A  - channels  0 to  7
  Port B  - channels  8 to 15
  Port CL - channels 16 to 19
  Port CH - channels 20 to 23

Only mode 0 of the 8255 chips is supported.

Each CTR is a 8254 chip providing 3 16-bit counter channels.  Each
channel is configured individually with INSN_CONFIG instructions.  The
specific type of configuration instruction is specified in data[0].
Some configuration instructions expect an additional parameter in
data[1]; others return a value in data[1].  The following configuration
instructions are supported:

  INSN_CONFIG_SET_COUNTER_MODE.  Sets the counter channel's mode and
    BCD/binary setting specified in data[1].

  INSN_CONFIG_8254_READ_STATUS.  Reads the status register value for the
    counter channel into data[1].

  INSN_CONFIG_SET_CLOCK_SRC.  Sets the counter channel's clock source as
    specified in data[1] (this is a hardware-specific value).  Not
    supported on PC214E.  For the other boards, valid clock sources are
    0 to 7 as follows:

      0.  CLK n, the counter channel's dedicated CLK input from the SK1
        connector.  (N.B. for other values, the counter channel's CLKn
        pin on the SK1 connector is an output!)
      1.  Internal 10 MHz clock.
      2.  Internal 1 MHz clock.
      3.  Internal 100 kHz clock.
      4.  Internal 10 kHz clock.
      5.  Internal 1 kHz clock.
      6.  OUT n-1, the output of counter channel n-1 (see note 1 below).
      7.  Ext Clock, the counter chip's dedicated Ext Clock input from
        the SK1 connector.  This pin is shared by all three counter
        channels on the chip.

  INSN_CONFIG_GET_CLOCK_SRC.  Returns the counter channel's current
    clock source in data[1].  For internal clock sources, data[2] is set
    to the period in ns.

  INSN_CONFIG_SET_GATE_SRC.  Sets the counter channel's gate source as
    specified in data[2] (this is a hardware-specific value).  Not
    supported on PC214E.  For the other boards, valid gate sources are 0
    to 7 as follows:

      0.  VCC (internal +5V d.c.), i.e. gate permanently enabled.
      1.  GND (internal 0V d.c.), i.e. gate permanently disabled.
      2.  GAT n, the counter channel's dedicated GAT input from the SK1
        connector.  (N.B. for other values, the counter channel's GATn
        pin on the SK1 connector is an output!)
      3.  /OUT n-2, the inverted output of counter channel n-2 (see note
        2 below).
      4.  Reserved.
      5.  Reserved.
      6.  Reserved.
      7.  Reserved.

  INSN_CONFIG_GET_GATE_SRC.  Returns the counter channel's current gate
    source in data[2].

Clock and gate interconnection notes:

  1.  Clock source OUT n-1 is the output of the preceding channel on the
  same counter subdevice if n > 0, or the output of channel 2 on the
  preceding counter subdevice (see note 3) if n = 0.

  2.  Gate source /OUT n-2 is the inverted output of channel 0 on the
  same counter subdevice if n = 2, or the inverted output of channel n+1
  on the preceding counter subdevice (see note 3) if n < 2.

  3.  The counter subdevices are connected in a ring, so the highest
  counter subdevice precedes the lowest.

The 'INTERRUPT' subdevice pretends to be a digital input subdevice.  The
digital inputs come from the interrupt status register.  The number of
channels matches the number of interrupt sources.  The PC214E does not
have an interrupt status register; see notes on 'INTERRUPT SOURCES'
below.

When an interrupt source is enabled in the interrupt source enable
register, a rising edge on the source signal latches the corresponding
bit to 1 in the interrupt status register.

When the interrupt status register value as a whole (actually, just the
6 least significant bits) goes from zero to non-zero, the board will
generate an interrupt.  For level-triggered hardware interrupts (PCI
card), the interrupt will remain asserted until the interrupt status
register is cleared to zero.  For edge-triggered hardware interrupts
(ISA card), no further interrupts will occur until the interrupt status
register is cleared to zero.  To clear a bit to zero in the interrupt
status register, the corresponding interrupt source must be disabled
in the interrupt source enable register (there is no separate interrupt
clear register).

The PC214E does not have an interrupt source enable register or an
interrupt status register; its 'INTERRUPT' subdevice has a single
channel and its interrupt source is selected by the position of jumper
J5.

COMMANDS

The driver supports a read streaming acquisition command on the
'INTERRUPT' subdevice.  The channel list selects the interrupt sources
to be enabled.  All channels will be sampled together (convert_src ==
TRIG_NOW).  The scan begins a short time after the hardware interrupt
occurs, subject to interrupt latencies (scan_begin_src == TRIG_EXT,
scan_begin_arg == 0).  The value read from the interrupt status register
is packed into a sampl_t value, one bit per requested channel, in the
order they appear in the channel list.

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 3 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.

  1) All channels on the PCI224 share the same range.  Any change to the
     range as a result of insn_write or a streaming command will affect
     the output voltages of all channels, including those not specified
     by the instruction or command.

  2) For the analog output command,  the first scan may be triggered
     falsely at the start of acquisition.  This occurs when the DAC scan
     trigger source is switched from 'none' to 'timer' (scan_begin_src =
     TRIG_TIMER) or 'external' (scan_begin_src == TRIG_EXT) at the start
     of acquisition and the trigger source is at logic level 1 at the
     time of the switch.  This is very likely for TRIG_TIMER.  For
     TRIG_EXT, it depends on the state of the external line and whether
     the CR_INVERT flag has been set.  The remaining scans are triggered
     correctly.

Configuring a "amplc_pci230" will match any supported card and it will
choose the best match, picking the "+" models if possible.  Configuring
a "pci230" will match a PCI230 or PCI230+ card and it will be treated as
a PCI230.  Configuring a "pci260" will match a PCI260 or PCI260+ card
and it will be treated as a PCI260.  Configuring a "pci230+" will match
a PCI230+ card.  Configuring a "pci260+" will match a PCI260+ card.

AI Subdevice:

  The AI subdevice has 16 single-ended channels or 8 differential
  channels.

  The PCI230 and PCI260 cards have 12-bit resolution.  The PCI230+ and
  PCI260+ cards have 16-bit resolution.

  For differential mode, use inputs 2N and 2N+1 for channel N (e.g. use
  inputs 14 and 15 for channel 7).  If the card is physically a PCI230
  or PCI260 then it actually uses a "pseudo-differential" mode where the
  inputs are sampled a few microseconds apart.  The PCI230+ and PCI260+
  use true differential sampling.  Another difference is that if the
  card is physically a PCI230 or PCI260, the inverting input is 2N,
  whereas for a PCI230+ or PCI260+ the inverting input is 2N+1.  So if a
  PCI230 is physically replaced by a PCI230+ (or a PCI260 with a
  PCI260+) and differential mode is used, the differential inputs need
  to be physically swapped on the connector.

  The following input ranges are supported:

    0 => [-10, +10] V
    1 => [-5, +5] V
    2 => [-2.5, +2.5] V
    3 => [-1.25, +1.25] V
    4 => [0, 10] V
    5 => [0, 5] V
    6 => [0, 2.5] V

AI Commands:

  +=========+==============+===========+============+==========+
  |start_src|scan_begin_src|convert_src|scan_end_src| stop_src |
  +=========+==============+===========+============+==========+
  |TRIG_NOW | TRIG_FOLLOW  |TRIG_TIMER | TRIG_COUNT |TRIG_NONE |
  |TRIG_INT |              |TRIG_EXT(3)|            |TRIG_COUNT|
  |         |              |TRIG_INT   |            |          |

  +---------+--------------+-----------+------------+----------+

  Note 1: If AI command and AO command are used simultaneously, only
          one may have scan_begin_src == TRIG_TIMER.

  Note 2: For PCI230 and PCI230+, scan_begin_src == TRIG_EXT uses
          DIO channel 16 (pin 49) which will need to be configured as
          a digital input.  For PCI260+, the EXTTRIG/EXTCONVCLK input
          (pin 17) is used instead.  For PCI230, scan_begin_src ==
          TRIG_EXT is not supported.  The trigger is a rising edge
          on the input.

  Note 3: For convert_src == TRIG_EXT, the EXTTRIG/EXTCONVCLK input
          (pin 25 on PCI230(+), pin 17 on PCI260(+)) is used.  The
          convert_arg value is interpreted as follows:

            convert_arg == (CR_EDGE | 0) => rising edge
            convert_arg == (CR_EDGE | CR_INVERT | 0) => falling edge
            convert_arg == 0 => falling edge (backwards compatibility)
            convert_arg == 1 => rising edge (backwards compatibility)

  All entries in the channel list must use the same analogue reference.
  If the analogue reference is not AREF_DIFF (not differential) each
  pair of channel numbers (0 and 1, 2 and 3, etc.) must use the same
  input range.  The input ranges used in the sequence must be all
  bipolar (ranges 0 to 3) or all unipolar (ranges 4 to 6).  The channel
  sequence must consist of 1 or more identical subsequences.  Within the
  subsequence, channels must be in ascending order with no repeated
  channels.  For example, the following sequences are valid: 0 1 2 3
  (single valid subsequence), 0 2 3 5 0 2 3 5 (repeated valid
  subsequence), 1 1 1 1 (repeated valid subsequence).  The following
  sequences are invalid: 0 3 2 1 (invalid subsequence), 0 2 3 5 0 2 3
  (incompletely repeated subsequence).  Some versions of the PCI230+ and
  PCI260+ have a bug that requires a subsequence longer than one entry
  long to include channel 0.

AO Subdevice:

  The AO subdevice has 2 channels with 12-bit resolution.

  The following output ranges are supported:

    0 => [0, 10] V
    1 => [-10, +10] V

AO Commands:

  +=========+==============+===========+============+==========+
  |start_src|scan_begin_src|convert_src|scan_end_src| stop_src |
  +=========+==============+===========+============+==========+
  |TRIG_INT | TRIG_TIMER(1)| TRIG_NOW  | TRIG_COUNT |TRIG_NONE |
  |         | TRIG_EXT(2)  |           |            |TRIG_COUNT|
  |         | TRIG_INT     |           |            |          |
  +---------+--------------+-----------+------------+----------+

  Note 1: If AI command and AO command are used simultaneously, only
          one may have scan_begin_src == TRIG_TIMER.

  Note 2: scan_begin_src == TRIG_EXT is only supported if the card is
          configured as a PCI230+ and is only supported on later
          versions of the card.  As a card configured as a PCI230+ is
          not guaranteed to support external triggering, please consider
          this support to be a bonus.  It uses the EXTTRIG/ EXTCONVCLK
          input (PCI230+ pin 25).  Triggering will be on the rising edge
          unless the CR_INVERT flag is set in scan_begin_arg.

  The channels in the channel sequence must be in ascending order with
  no repeats.  All entries in the channel sequence must use the same
  output range.

DIO Subdevice:

  The DIO subdevice is a 8255 chip providing 24 DIO channels.  The DIO
  channels are configurable as inputs or outputs in four groups:

    Port A  - channels  0 to  7
    Port B  - channels  8 to 15
    Port CL - channels 16 to 19
    Port CH - channels 20 to 23

  Only mode 0 of the 8255 chip is supported.

  Bit 0 of port C (DIO channel 16) is also used as an external scan
  trigger input for AI commands on PCI230 and PCI230+, so would need to
  be configured as an input to use it for that purpose.

AI Triggering:
   For start_src == TRIG_EXT, the A/D EXTERNAL TRIGGER IN (pin 45) is used.
   For 1602 series, the start_arg is interpreted as follows:

     start_arg == CR_INVERT           => gated triger (level low)
     start_arg == CR_EDGE             => Rising edge
     start_arg == CR_EDGE | CR_INVERT => Falling edge

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.

Configuration Options:
  [0] PCI bus (optional)
  [1] PCI slot (optional)
  [2] analog output range jumper setting
      0 == +/- 5 V
      1 == +/- 10 V

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.

Subdevices 0 is digital I/O, subdevice 1 is digital input, and
subdevice 2 is digital output.  Unlike other Comedi devices,
subdevice 0 defaults to output.

Pins 13 and 14 are inverted once by Comedi and once by the
hardware, thus cancelling the effect.

Pin 1 is a strobe, thus acts like one.  There's no way in software
to change this, at least on a standard parallel port.

Subdevice 3 pretends to be a digital input subdevice, but it always
returns 0 when read.  However, if you run a command with
scan_begin_src=TRIG_EXT, it uses pin 10 as a external triggering
pin, which can be used to wake up tasks.

This driver requires RTAI or RTLinux to work correctly.  It doesn't
actually drive hardware directly, but calls other drivers and uses
a real-time task to emulate commands for drivers and devices that
are incapable of native commands.  Thus, you can get accurately
timed I/O on any device.

Since the timing is all done in software, sampling jitter is much
higher than with a device that has an on-board timer, and maximum

This driver supports a single board - the CIO-DAS16/M1.
As far as I know, there are no other boards that have
the same register layout.  Even the CIO-DAS16/M1/16 is
significantly different.

I was _barely_ able to reach the full 1 MHz capability
of this board, using a hard real-time interrupt
(set the TRIG_RT flag in your comedi_cmd and use
rtlinux or RTAI).  The board can't do dma, so the bottleneck is
pulling the data across the ISA bus.  I timed the interrupt
handler, and it took my computer ~470 microseconds to pull 512
samples from the board.  So at 1 Mhz sampling rate,
expect your CPU to be spending almost all of its
time in the interrupt handler.

This board has some unusual restrictions for its channel/gain list.  If the
list has 2 or more channels in it, then two conditions must be satisfied:
(1) - even/odd channels must appear at even/odd indices in the list
(2) - the list must have an even number of entries.


irq can be omitted, although the cmd interface will not work without it.

This card has 16 analog inputs multiplexed onto a 12 bit ADC.  There
is a minimally useful onboard clock.  The base frequency for the
clock is selected by jumpers, and the clock divider can be selected
via programmed I/O.  Unfortunately, the clock divider can only be
a power of 10, from 1 to 10^7, of which only 3 or 4 are useful.  In
addition, the clock does not seem to be very accurate.

A very simple digital I/O card.  Four banks of 8 lines, each bank
is configurable for input or output.  One wonders why it takes a
50 page manual to describe this thing.

The driver (which, btw, is much less than 50 pages) has 1 subdevice
with 32 channels, configurable in groups of 8.

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.

emu as port A output, port B input, port C N/A).

IRQ is assigned but not used.

Tested with lab-pc-1200.  For the older Lab-PC+, not all input ranges
and analog references will work, the available ranges/arefs will
depend on how you have configured the jumpers on your board
(see your owner's manual).

Kernel-level ISA plug-and-play support for the lab-pc-1200
boards has not
yet been added to the driver, mainly due to the fact that
I don't know the device id numbers.  If you have one
of these boards,
please file a bug report at https://bugs.comedi.org/
so I can get the necessary information from you.

The 1200 series boards have onboard calibration dacs for correcting
analog input/output offsets and gains.  The proper settings for these
caldacs are stored on the board's eeprom.  To read the caldac values
from the eeprom and store them into a file that can be then be used by
comedilib, use the comedi_calibrate program.

Configuration options - ISA boards:
  [0] - I/O port base address
  [1] - IRQ (optional, required for timed or externally triggered conversions)
  [2] - DMA channel (optional)

Configuration options - PCI boards:
  [0] - bus (optional)
  [1] - slot (optional)

The Lab-pc+ has quirky chanlist requirements
when scanning multiple channels.  Multiple channel scan
sequence must start at highest channel, then decrement down to
channel 0.  The rest of the cards can scan down like lab-pc+ or scan
up from channel zero.  Chanlists consisting of all one channel
are also legal, and allow you to pace conversions in bursts.

The DIO-96 appears as four 8255 subdevices.  See the 8255
driver notes for details.

The DIO32HS board appears as one subdevice, with 32 channels.
Each channel is individually I/O configurable.  The channel order
is 0=A0, 1=A1, 2=A2, ... 8=B0, 16=C0, 24=D0.  The driver only
supports simple digital I/O; no handshaking is supported.

DMA mostly works for the PCI-DIO32HS, but only in timed input mode.

The PCI-DIO-32HS/PCI-6533 has a configurable external trigger. Setting
scan_begin_arg to 0 or CR_EDGE triggers on the leading edge. Setting
scan_begin_arg to CR_INVERT or (CR_EDGE | CR_INVERT) triggers on the
trailing edge.

This driver could be easily modified to support AT-MIO32HS and
AT-MIO96.

The PCI-6534 requires a firmware upload after power-up to work, the
firmware data and instructions for loading it with comedi_config
it are contained in the

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
comedi_calibrate (or comedi_soft_calibrate for m-series) utility.
M-Series boards do analog input and analog output calibration entirely
in software. The software calibration corrects
the analog input for offset, gain and
nonlinearity.  The analog outputs are corrected for offset and gain.
See the comedilib documentation on comedi_get_softcal_converter() for
more information.

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

Digital I/O may not work on 673x.

Note that the PCI-6143 is a simultaineous sampling device with 8 convertors.
With this board all of the convertors perform one simultaineous sample during
a scan interval. The period for a scan is used for the convert time in a
Comedi cmd. The convert trigger source is normally set to TRIG_NOW by default.

The RTSI trigger bus is supported on these cards on
subdevice 10. See the comedilib documentation for details.

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.

SCXI is probably broken for m-series boards.
