Subject: simple event counting with ni_6602

Hi all,

I've been using an NI-6602 for quadrature encoder readout since four years
or so. This week, I tried to program another counter on the same board to
do simple event counting, according to the example in the comedilib demo
directory.

For some reason, I cannot set the counter to other numbers than 0 (using
comedi_data_write) and reading the counter (comedi_data_read) gives me no
other numbers than 0, no matter how many pulses I feed into the counter.
There's another thread, related to this topic, by Kylar, but this does not
supply an answer to the problem.

So my question is: Does anyone  have a working ni_660x, with simple event
counting functioning the way it should? If so, could you share the settings
of the flags needed to configure that counter properly?

TIA,

Marcel

Hi,

take a look at Counter set-up topic
http://groups.google.com/group/comedi_list/browse_thread/thread/589db...
If you take a look to the links I posted you find the defines with
comments which to use for 660x
