Dear All,
I am a little confused over here. I am unable to run the ao_waveform example even though i have installed everything properly. The error message was "command not supported" when i run the ao_waveform example. The card that i am using is a NI DAQ 6024E PCMCIA card.
I tried the ./info and got this message that reconfirmed that command is not supported for my AO port..
"
.
.
.
subdevice 1:
type: 2 (analog output)
number of channels: 2
max data value: 4095
ranges:
all chans : [1e-06,1e-06]
command:
not supported
.
.
.
"
Just a side note, all my other subdevices (eg DIO, counter, calibration etc) also have the command entry as "not supported". Only the subdevice (analog input) has a list of commands shown.
I think this AO port does have AO data FIFO as shown in the DAQ-STC manual from NI (page 1-4). Can anyone help me please?
Thanks a lot.
wee

Subject: Re: help with comedi and kernel 2.6.3
Hi!
It probably does. But I would go for the latest kernel which is on that
page. The early 2.6.x kernels are quite buggy and I recommend using a
later one.
As you can imagine I don't have any NI card. There's enough work with my
duxboard(s). ;-)

Hello Haavard,
do I understand it right that you are going to control motors with a
variable impulse/pause period? Thus, PWM?
My plan is the following: I'll just add another 4 channels. The first 4
analogue output channels are then the "real" analogue output channels.
The next 4 analogue output channels will become the PWM channels. In
this way the PWM output is completely transparent to the application.
The application is just seeing an analogue output channel.
How does that sound to you?

Subject: rtai_comedi.ko error
Hello,
I am trying to compile linux-2.6.7 + cvs rtai with comedi support. The
compilation is sucessful
but when I try to load rtai_comedi.ko , an error message says that there
are symbols undefined
In compilation several warning appear indicating that different symbols
are undefined, as for example
rt_get_time
The same problem appears compiling the cvs version of comedi, when i try
to load comedi.ko
i get an error due to undefined symbols
Anybody has the same problem?
thanks

Subject: Re: usbdux - rtai problem
Michael,
yes. Probably the hotplug script is not called automatically. I don't
know if the rtai patch has disabled the hotplug call.
There might be another reason: I've just seen that at least the CVS
version of comedi installs the hotplug script under
/usr/local/etc/hotplug. It must be unter /etc/hotplug. Thus:
./configure --sysconfdir=/etc
Anyway. You can simply issue the command by hand:
comedi_config -i /usr/share/usb/usbdux_firmware.hex /dev/comedi0 usbdux
If the firmware is not under /usr/share/usb it's under /usr/local/share/usb.

Hi!
It's nothing wrong with the buffer, it turned out.
I just had to configure the command to return for every scan, like:
cmd->flags |=3D TRIG_WAKE_EOS;
this is part of a comment in cmd.c.
Thanks anyway,
Christian
