5. Low-level drivers

5.1. 8255.o -- generic 8255 support

Author: ds

The classic in digital I/O.  Three channels of 8 bit digital I/O,
each channel is I/O configurable, channels 0 and 1 in 8 bit units,
channel 2 in 4 bit units.  The driver does not support modes 1 or 2
yet, since I don't really understand how they would potentially be used.
(Send me email if you want to use these modes.)  If and when
modes 1 and 2 are supported, there is a strong possibility that the
3rd channel will be split into two 4-bit channels.  (Refer to the
8255 spec for clues as to why.)

You should configure 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 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.




  

5.2. adl_pci9118.o -- Adlink PCI-9118DG, PCI-9118HG, PCI-9118HR

Author: Michal Dobes <majkl@tesnet.cz>

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 is know problem with this driver:
- If you use scan_begin_src=TRIG_EXT & convert_src=TRIG_TIMER
  then this mode sometimes discards some samples. :-((

Configuration options:
  [0] - PCI bus of device (optional)
  [1] - PCI slot of device (optional)
          If bus/slot is not specified, the first available PCI
          device will be used.

If you have an external multiplexer, the third option in the option
list should be used to indicate the number of channels in the
multiplexer.




  

5.3. adv_pci1710.o -- Advantech PCI-1710, PCI-1710HG, PCI-1711, PCI-1713, Advantech PCI-1720, PCI-1731

Author: Michal Dobes <majkl@tesnet.cz>

This driver supports AI, AO, DI and DO subdevices.
AI subdevice supports cmd and insn interface,
other subdevices support only insn interface.

The PCI-1710 and PCI-1710HG have the same PCI device ID, so the
driver cannot distinguish between them, as would be normal for a
PCI driver.

Configuration options:
  [0] - PCI bus of device (optional)
  [1] - PCI slot of device (optional)
          If bus/slot is not specified, the first available PCI
          device will be used.




  

5.4. amplc_pci230.o -- Driver for Amplicom PCI230 and PCI260 Multifunction I/O boards

Author: Allan Willcox <allanwillcox@ozemail.com.au>

5.5. cb_pcidas.o -- Driver for the ComputerBoards/MeasurementComputing cards of the PCI-DAS series with the AMCC S5933 PCI controller.

Author: Ivan Martinez <ivanmr@altavista.com>, Frank Mori Hess <fmhess@uiuc.edu>

  The boards' autocalibration features are not yet supported.


Configuration options:
  [0] - PCI bus of device (optional)
  [1] - PCI slot of device (optional)
  If bus/slot is not specified, the first available PCI
  device will be used.

For commands, the scanned channels must be consecutive
(i.e. 4-5-6-7, 2-3-4,...), and must all have the same
range and aref.




  

5.6. cb_pcidas64.o -- Driver for the ComputerBoards/MeasurementComputing PCI-DAS64xxx series with the PLX 9080 PCI controller.

Author: Frank Mori Hess <fmhess@uiuc.edu>

Basic insn support should work, but untested as far as I know.
Has command support for analog input, which may also work.  Support
for pci dma transfers can be enabled by editing the source to #define
PCIDMA instead of #undef'ing it. This driver is in need of stout-hearted
testers who aren't afraid to crash their computers in the name of progress.
Feel free to send and success/failure reports to author.

Some devices are not identified because the PCI device IDs are not known.




  

5.7. cb_pcidda.o -- ComputerBoards/MeasurementComputing PCI-DDA series

Author: Ivan Martinez <ivanmr@altavista.com>, Frank Mori Hess <fmhess@users.sourceforge.net>

Configuration options:
  [0] - PCI bus of device (optional)
  [1] - PCI slot of device (optional)
  If bus/slot is not specified, the first available PCI
  device will be used.

Only simple analog output writing is supported.

SO FAR IT HAS ONLY BEEN TESTED WITH:
  - PCI-DDA08/12
PLEASE REPORT IF YOU ARE USING IT WITH A DIFFERENT CARD

5.8. comedi_parport.o -- Standard PC parallel port

Author: ds

A cheap and easy way to get a few more digital I/O lines.  Steal
additional parallel ports from old computers or your neighbors'
computers.

Option list:
 0: I/O port base for the parallel port.
 1: IRQ

Parallel Port Lines:

pin     subdev  chan    aka
---     ------  ----    ---
1       2       0       strobe
2       0       0       data 0
3       0       1       data 1

13      1       1       printer selected
14      2       1       auto LF
15      1       0       error
16      2       2       init
17      2       3       select printer
18-25   ground


Channel 0 and 2 are output, channel 1 is input.  I know that it
is possible to change this with ECP/EPP parallel ports, but this
driver is a cheap hack.

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 13 as a external triggering
pin, which can be used to wake up tasks.  (or is that pin 10. --ds)




  

5.9. comedi_rt_timer.o -- Command emulator using real-time tasks

Author: ds

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
sample rate is much lower.

Configuration options:
  [0] - device index
  [1] - subdevice index




  

5.10. daqboard2000.o -- IOTech DAQBoard/2000

Author: Anders Blomdell <anders.blomdell@control.lth.se>

Much of the functionality of this driver was determined from reading
the source code for the Windows driver.

The FPGA on the board requires initialization code, which can either
be compiled into the driver or loaded by comedi_config using the -i
option.  The latter is recommended, in order to save a bit of kernel
memory.

Configuration options:
  [0] - pointer to FPGA initialization data
          The pointer and size options are handled automatically
          by comedi_config when you use the -i option.
  [1] - size of FPGA data




  

5.11. das08.o -- DAS-08 compatible boards

Author: Anders Blomdell <anders.blomdell@control.lth.se>

This is a rewrite of the das08 and das08jr drivers.

Options (for ISA cards):
        [0] - base io address

Options (for pci-das08):
        [0] - bus  (optional)
        [1] = slot (optional)
Use the name 'pci-das08' for the pci-das08, NOT 'das08'.

Options (for pcm-das08):
        NONE

The das08 driver doesn't support asynchronous commands, since
the cheap das08 hardware doesn't really support them (except for
pcm-das08).  The
comedi_rt_timer driver can be used to emulate commands for this
driver.




  

5.12. das16.o -- DAS16 compatible boards

Author: Anders Blomdell <anders.blomdell@control.lth.se>

A rewrite of the das16 and das1600 drivers.

Passing a zero for an option is the same as leaving it unspecified.

Both an irq line and dma channel are required for timed or externally
triggered conversions.




  

5.13. das16m1.o -- CIO-DAS16/M1

Author: Anders Blomdell <anders.blomdell@control.lth.se>

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.




  

5.14. das1800.o -- Keithley Metrabyte DAS1800 (& compatibles)

Author: Frank Mori Hess <fmhess@uiuc.edu>

The waveform analog output on the 'ao' cards is not supported.
If you need it, send me (Frank Hess) an email.

Configuration options:
  [0] - I/O port base address
  [1] - IRQ (optional, required for timed or externally triggered conversions)
  [2] - DMA0 (optional, requires irq)
  [3] - DMA1 (optional, requires irq and dma0)




  

5.15. das6402.o -- Keithley Metrabyte DAS6402 (& compatibles)

5.19. dt2814.o -- Data Translation DT2814

Author: ds

Configuration options:
  [0] - I/O port base address
  [1] - IRQ

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.




  

5.20. dt2815.o -- Data Translation DT2815

5.21. dt2817.o -- Data Translation DT2817

Author: ds

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.

Configuration options:
  [0] - I/O port base base address

5.27. mpc8260cpm.o -- MPC8260 CPM module generic digital I/O lines

Author: ds

This driver is specific to the Motorola MPC8260 processor, allowing
you to access the processor's generic digital I/O lines.




  

5.28. multiq3.o -- Quanser Consulting MultiQ-3

Author: Anders Blomdell <anders.blomdell@control.lth.se>

5.29. ni_670x.o -- National Instruments 670x

Author: Bart Joris <bjoris@advalvas.be>

The driver currently does not recognize the 6704, because the PCI
ID is not known.




  

5.30. ni_at_a2150.o -- National Instruments AT-A2150

Author: Frank Mori Hess

If you want to ac couple the board's inputs, use AREF_OTHER.

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




  

5.31. ni_atmio.o -- National Instruments AT-MIO-E series

Author: ds

The isapnptools package is required to use this board.  Use isapnp to
configure the I/O base for the board, and then pass the same value as
a parameter in comedi_config.  A sample isapnp.conf file is included
in the etc/ directory.

Assuming that the NI spec is correct, the driver should correctly
identify every board in the series.  Each channel should have the
appropriate parameters, i.e., input/output ranges, number of bits,
etc.  If the driver fails to recognize your card or does not have
the correct parameters, please contact me.

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.

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




  

5.32. ni_atmio16d.o -- National Instruments AT-MIO-16D

Author: Chris R. Baugher <baugher@enteract.com>

5.33. ni_labpc.o -- National Instruments Lab-PC (& compatibles)

Author: Frank Mori Hess <fmhess@users.sourceforge.net>

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)

Configuration options - PCMCIA boards:
  none

Lab-pc+ has quirky chanlist when scanning multiple channels.  Scan sequence must start
at highest channel, then decrement down to channel 0.  1200 series cards can scan down
like lab-pc+ or scan up from channel zero.




  

5.34. ni_mio_cs.o -- National Instruments DAQCard E series

Author: ds

See the notes in the ni_atmio.o driver.




  

5.35. ni_pcidio.o -- National Instruments PCI-DIO32HS, PCI-DIO96, PCI-6533, PCI-6503

Author: ds

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,
as one might guess, is 0=A0, 1=A1, 2=A2, ... 8=B0, 16=C0, 24=D0.

DMA is halfway completed, but not operational, for the PCI-DIO32HS.

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




  

5.36. ni_pcimio.o -- National Instruments PCI-MIO-E series (all boards)

Author: ds

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 above for
ni_atmio.o for additional information about these boards.

Comedi knows the PCI ID codes for many of the boards in this series,
but the NI documentation is incomplete in this matter.  If you have
a PCI-MIO board that Comedi doesn't recognize, send me the PCI device
ID, as can be found in /proc/pci or the output of lspci.  The vendor
code for National Instruments is 0x1093.  I will include the ID in
the next version.

DMA is halfway completed, but not yet operational.




  

5.37. pcl711.o -- Advantech PCL-711 and 711b, ADLink ACL-8112

Author: ds

Since these boards do not have DMA or FIFOs, only immediate mode is

Author: Michal Dobes <majkl@tesnet.cz>

This driver supports insn and cmd interfaces. Some boards support only insn
becouse their hardware don't allow more (PCL-813/B, ACL-8113, ISO-813).
Data transfer over DMA is supported only when you measure only one
channel, this is too hardware limitation of these boards.
See the head of the source file pcl812.c for configuration options.




  

5.42. pcl818.o -- Advantech PCL-818 cards, PCL-718

Author: Michal Dobes <majkl@tesnet.cz>

All cards have 16 SE/8 DIFF ADCs, one or two DACs, 16 DI and 16 DO.
Differences are only at maximal sample speed, range list and FIFO
support.
The driver support AI mode 0, 1, 3 other subdevices (AO, DI, DO) support
only mode 0. If DMA/FIFO/INT are disabled then AI support only mode 0.
PCL-818HD and PCL-818HG support 1kword FIFO. Driver support this FIFO
but this code is untested.
A word or two about DMA. Driver support DMA operations at two ways:
1) DMA uses two buffers and after one is filled then is generated
   INT and DMA restart with second buffer. With this mode I'm unable run
   more that 80Ksamples/secs without data dropouts on K6/233.
2) DMA uses one buffer and run in autoinit mode and the data are
   from DMA buffer moved on the fly with 2kHz interrupts from RTC.
   This mode is used if the interrupt 8 is available for allocation.
   If not, then first DMA mode is used. With this I can run at
   full speed one card (100ksamples/secs) or two cards with
   60ksamples/secs each (more is problem on account of ISA limitations).
   To use this mode you must have compiled  kernel with disabled
   "Enhanced Real Time Clock Support".
   Maybe you can have problems if you use xntpd or similar.
   If you've data dropouts with DMA mode 2 then:
    a) disable IDE DMA
    b) switch text mode console to fb.
See the head of the source file pcl818.c for configuration options.
