How can I do this using the comedi API? 2. I You should be able to use external triggers by setting TRIG_EXT as the start_src, scan_begin_src, or convert_src. I don't know how well tested it is though. > would also like to use Analog I/O from a RTlinux module? Will I be able to Yes > do this? 3. Does anyone have code for calibrating the PCI-DAS 1602/12? The comedi/comedilib cvs has calibration code for the cb_pcidas driver. It will only calibrate one analog input range at the moment though. The infrastructure for calibrating multiple ranges is in cvs, but specific support for multiple ranges with cb_pcidas hasn't been added to comedi_calibrate yet. > 4.

It will prevent the interrupt handler from running at RT priority, which may or may not matter to you. - -- Frank -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (GNU/Linux) Comment: For info see http://www.gnupg.org iD8DBQE+ndVn5vihyNWuA4URAlOkAJsH5AbI2nmAMeV2HD2XuZv1nIp+uACferJt VgGCL/EImIANB173els73xk= =Okef -----END PGP SIGNATURE-----
