The trick is this: the command from emc2 to the 7i43 (or 5i20, or ...) is *not* "take a step", it's "keep stepping *at* *this* *rate* until i tell you otherwise". If you're familiar with the emc2 thread architecture, think of it as running the base thread on the FPGA. -- Sebastian Kuzminsky ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
