I think that things would be a lot simpler if you ignored IO pins and created both an input and an output pin for each IO pin. I think that the hostmot2 driver works this way, you can (for example) read stepgen outputs as inputs. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ "Accelerate Dev Cycles with Automated Cross-Browser Testing - For FREE Instantly run your Selenium tests across 300+ browser/OS combos.
