Hi...we have been trying to get a Measurement Computing DDA 08/16 board to talk to a simple process that writes a waveform to all analog output channels...in addition to this we are also trying to write a square wave over two digital lines to synchronize our code...the 8255's on the PCI DDA 08/16 should be accessible...however while loading the driver we notice two messages pop up saying "8255 support not configured -- disabling subdevice" i guess this prevents us from finishing the requirement on the current assignment...the board seems to respond ok on low frequency signal generation...is there anything we need to change on the install/config...our modules are loaded in order as 8255,cb_pcidda,cb_pcidas,kcomedilib,comedi after which we run the comedi_config command for the two boards in our rc.local as... "comedi_config /dev/comedi0 cb_pcidda" "comedi_config /dev/comedi1 cb_pcidas" -Ashish
