Does this mean that I do not need to even define gearchange.1.sel pin at all if I set gearchange.0.sel to be connected to the microswitch? Do you have gearchange implemented anywhere? Thanks Andy, this gearchange seems to be a godsend, and a good self documenting feature that is easies than a bunch of muxes to understand. i ------------------------------------------------------------------------------ Learn how Oracle Real Application Clusters (RAC) One Node allows customers to consolidate database storage, standardize their database environment, and, should the need arise, upgrade to a full multi-node Oracle RAC database without downtime or disruption http://p.sf.net/sfu/oracle-sfdevnl _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
