hallo, all
Last week I have compared my comdei_test results with Dr. Rolf Mueller's
and found that there are no applicable FIFO for subdevice 1 in my
PCI-6111 card. According to the Manual, there must be 2 FIFOs in
PCI-611x card(AI buffer8192 and AO buffer 2048), his 6110 card has FIFO
for subdevice 1 in test result, but my 6111's FIFO for AO is "not
applicable"(see below 1st attached file). I have at same time also tried
the example "simultaneous start" from David Schleef in his computer, it
runs right by his computer, but not by my computer, the synchronization
from this example lost contoll totally in my computer(see below 2rd
attached file).
So I thought that there were problems with my hardware or software. Then
I spent long time and painfully added the second kernel 2.4.20 direct
from www.Kernel.org in my computer, and changed comedi to CVS version ,
moved away the conflicting CDs(they leaded always to "BIOS not
installed"). But now the test result is nearly same as before.
I think these 2 FIFOs are important to making synchronization for high
frequncy application, especially for comedi under Redhatl. but where is
my "not applicabe "FIFO in subedevice 1?
By the way, I can test the normal outputted analoge waveform without
synchronization in Oscilloscope, it works also in some degree.
Can you give me some advices? Perhaps I have something ignored.
