It's not blatantly obvious, but I included R1-8 just to protect the GPIO ports from shorts. If the cable is shorted, you don't want to have a Voh GPIO and a Vol GPIO tied together. The resistors on the far end of the cable are significantly larger, so that the effects of the protection resistors are minimal. Example: R1-8 are 220 ohms each. R9-16 are more like 10k ohms. _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
