Hi,
I am a newbie in comedi. I am testing it to acquire data using two old ISA
DAQ cards, the NI lap-pc+ and Advantech pcl812pg. The example programs inp
and inpn work properly, but I cannot get the cmd program working. It blocks
when reading data from /dev/comedi (no data are readed). I have checked the
DMA and IRQ parameters of the
cards, and everithing seems to be properly configured and no conflicts are
present on the system (I enclose /sys/interrupts, /sys/dma /sys/comedi
and /sys/ioports at the end of this mail). My configuration is (though I have
tried some variations, which did not work):
pcl812pg:
Address=0x220 IRQ=6 DMA=3
lab-pc+:
Address=0x2C= IRQ=9 DMA=1
My linux system is Debian-3.0 with a 2.4.22 kernel (I have also tested kernel
2.4.20), running on a Pentium III 550 MHz PC. I have not installed the
realtime patches RTAI nor RTLinux. The comedi version is 0.7.67 and the
comedilib version is 0.7.21
I would like to sample waveforms using these card, and my intention was to
take the cmd program as an example to do this. I am not sure if it is a
problem of the drivers, the configuration, the library, the cmd.c example or
the specified parameters. I would appreciate any hint.
Thank you in advance and best regards,
Jose Manuel Cano Garcia
