It's pretty easy to make a VFD/Modbus component for a new VFD, or other Modbus device. I have some notes here: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?New_File_From_Vfs11 I seem to recall that some further work had been done when libmodbus3 came out, but I don't recall any details. Rather than try to make a generic VFD/Modbus driver, it's easy enough to just edit an existing file as needed. For those that don't know how to edit C files, it may be best to announce to the list the needed Modbus device and offer sufficient motivation. I believe there is an appropriate place to collect existing Modbus drivers on the Wiki. One issue that I vaguely recall, so far, Modbus drivers are either written to be compiled on their own with a corresponding Makefile, or the driver is meant to be placed in the LinuxCNC source with a Makefile that follows the source tree (?). If this is correct, it would be nice to resolve which (or both?) method should be used and document it. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
