I have 16 of these chips, all talking to a single MCU. The 8 on one side have their own analog power/gnd, and the 8 on the other side have their own. The board will go inside my circuit breaker panel box, powered by a USB cable. board: http://www.delorie.com/pcb/powermeter.jpg http://www.delorie.com/pcb/powermeter.pcb _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
