I2C is driven from both "ends" of the bus, so if you want to use the pull-ups as terminators, use two resistors, each twice the resistance, one at each end.
I've never heard of anyone worrying about ringing on I2C though... _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
