More fun: I replaced the D-FF with a pair of XOR gates (dual xor available in US8 package); one wired to show "in phase" and one for "out of phase". The two LEDs kind of "throb" back in forth, instead of blinking (because when they're 90 degrees out of phase, both LEDs are on 50% of the time, etc). _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
