Several of the existing drivers work this way. Getting encoder counts and sending out a velocity command every servo cycle is the basic HAL model EMC uses to run servos. The mesa/hostmot2 and motenc drivers do this with a PCI interface, the ppmc and pluto devices use EPP over the parallel port, and the STG uses the ISA bus. Maybe study one or all of those drivers and then come back with more specific questions? (Also, the emc-developers list might be a better place for this) Chris ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
