Sure it can. I think Chris is requesting that the two paragraphs of explanation of why the pinouts themselves cannot be in the manual, should be in the manual. ;-) >> One thing I would suggest is writing up a Hostmot2 sample that would >> emulate >> the original driver -I guess that is the 4 channel servo/8 step driver >> firmware >> with the step drivers turned off?

The 7i33 uses the "standard Mesa 4x servo pinout", so i think *all* of the available HostMot2 firmwares should work with a 7i33 on the first connector. -- Sebastian Kuzminsky Why do we even pretend to have nations these days? -- Bruce Sterling <http://www.seedmagazine.com/news/2009/01/2009_will_be_a_year_of_panic.php> ------------------------------------------------------------------------------ Open Source Business Conference (OSBC), March 24-25, 2009, San Francisco, CA -OSBC tackles the biggest issue in open source: Open Sourcing the Enterprise -Strategies to boost innovation and cut costs with open source participation -Receive a $600 discount off the registration fee with the source code: SFAD http://p.sf.net/sfu/XcvMzF8H _______________________________________________ Emc-developers mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-developers
