LXRT with Comedi

Hi All,

   I have coded a little program to output a periodic digital pulses to run in LXRT.  As LXRT has
rt_make_soft_real_time() and rt_make_hard_real_time(), i have tried to compare the "reliability" by
checking the frequency of the digital pulses through an oscilloscope.

   However to my surprise, under the soft realtime option, the output on my oscilloscope is stable up to 10kHz,
whereas under the hard realtime option, the output starts to produce "unstable" waveform at a low
freqency of 500Hz!!!

   I suspect that my code has not fully utilised the hard realtime option but i do not know what is wrong. Can
anyone help me to take a look?  I am using rtai-24.1.11, linux-2.4.20-rthal5g, comedi-0.7.65 and
comedilib-0.7.21.  I am using a NI DAQ6024E card.  I loaded rt_lxrt_old.o, rtai.o and rt_sched_up.o for
the lxrt.

   Thanks and my code is attached below.

Problem when "make" comedilib-0.7.21

Hi,

I have try to run “make” to compile the comedilib-0.7.21.

But I encounter some errors… following are the error message?

Problem when running "comedi_config"

Hi,

I have problem running the “comedi_config”.

After running “modprobe ni_labpc_cs” successfully, I tried “comedi_config –v /dev/comedi0 lab-pc-1200 0x200,4”, but I got the error message:

Configuring driver=lab-pc-1200 512,4,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0

Configure failed: Invalid argument

Check kernel log for information

Possible reasons for failure:

After “dmesg” is got the mnessage:

Comedi0: ni_labpc: lab-pc-1200, io 0x200, irq 4

Unable to allocate irq 4

Comedi0: ni_labpc: detach

Anyone can help me here?

regards,

Waiyong

comedi_data_read with python

Hi all,

I have a problem with comedi_data_read(...) function using python.
I've done this simple example, taken from demo dir of the comedilib
tarball, but it doesn't work:

###############################################

import comedi as c
import time

subdev = 0
chan = 0 
range = 0 
aref = 0 

cf = c.comedi_open('/dev/comedi0')
maxdata = c.comedi_get_maxdata(cf, subdev, chan)
cr = c.comedi_get_range(cf, subdev, chan, range)
data = 100

print "Writing data"
if c.comedi_data_write(cf, subdev, chan, range, aref, data) == -1:
  print "Error writing device"

print "Reading data"
if c.comedi_data_read(cf, subdev, chan, range, aref, data) == -1:
  print "Error reading device"

volts = c.comedi_to_phys(data, cr, maxdata)
print '%d %g\n'%(data, volts)

###############################################################

this is the error from python interpreter:

  Traceback (most recent call last):
    File "tut2.py", line 34, in ?
        if c.comedi_data_read(cf, subdev, chan, range, aref, data) == -1:
        TypeError: Type error. Expected _p_lsampl_t

in C library lsampl_t is an un unsigned int, it seems that python
doesn't like my "data" variable ?

Would you please help me?

Thank you very much

Marco Pagnanini

Probably something else has allocated irq 4.  It's an isa board, and it 
can't share interrupts.  Would you send me the output of pnpdump for the 
board?  I might get around to adding kernel level isapnp support for the 
board if I had it's id numbers, so you dont have to use isapnptools.

Re: Error when "make" for comedilib-0.7.21

Hello,

        All that I know is that this error can be fixed with the
docbook-sgml utility, because it worked for me. There could be other
ways which I am not aware of. Try searching the comedi archives ( and
also rtai ) and you may find an alternative.

Regards,

Raghu

newbie: error in "make" for comedi

hi
I am new to linux and am trying to install comedi for NI PCI 6052E. I am running Red Hat 9.0 with kernel version 2.4.20-18.9 and gcc version 3.2.3.
The comedi version i downloaded and was trying to install is comedi-0.7.68

I did the following steps:
cd /usr/src/linux2.4.20-18.9/
make mrproper
cp /configs/kernel-2.4.20-i686.config .config
make oldconfig
make dep

Then in the comedi-0.7.68 directory i run "./configure" which generates the Makefile.

there is no rule for 'make config' so i directly ran "make"

and i get an error , I am posting the last part of the build log here for reference.

I would really appreciate some help in solving this problem..

advantech pci-1760

hello,
i've got an advantech pci-1760 which I'm trying to access using
comedi-0.7.68 and comedilib-0.7.21. the driver and the lib compiled fine and
without errors, the driver can be loaded successfully and comedi_config is
able to assign it to a device file. but the card isnt working at all. its
not possible to get any of the relays working. I tried all the ways
comedilib offers to acomplish such task (comedi_data_write,
comedi_dio_write, comedi_dio_bitfield, comedi_do_insn (with INSN_WRITE) and
comedi_do_insn (with INSN_BITS)). Most of these call return without error
(except comedi_do_insn which is returning 1 which seems to be undocumented),
but all of them are writing the same message to the syslogd:

comedi0: adv_pci_dio: PCI-1760 mailbox request timeout!
comedi0: adv_pci_dio: PCI-1760 mailbox request timeout!
comedi0: adv_pci_dio: PCI-1760 mailbox request timeout!
comedi0: adv_pci_dio: PCI-1760 mailbox request timeout!
comedi0: adv_pci_dio: PCI-1760 mailbox request timeout!
comedi0: adv_pci_dio: PCI-1760 mailbox request timeout!

does anybody know what that means, and how to avoid it. Has anybody ever
heard of someone who got this card working with linux. and what do I have to
do to acomplish that myself.

thanx in advance.
Milan Wölke
