> Isn't that whole outside perimeter plane GND? Yeah, but I usually try to keep the caps closer to the ground pins as well as the vdd pins. A lot of the chips I usually deal with (like the R8C) have the power pins near each other so you can bypass right at the chip.

Cell phone noise made it in via the cables. Hmmm... I'm not sure I need to worry about that. The current sensors are 100% differential, the digital signals are slow compared to the pcb size and have series resistors, and I'm only using this for personal benefit. But then again, I'm also doing one hand-made prototype first ;-) > > The two *.sch I posted are all there is; I have a Makefile that just > > renames the one channel to the other fifteen of them. > > That's cheating :-) No, that's *scripting* :-) I even have a PCB script to copy all 16 of the layout blocks to a blank board, but now that it's almost done, it's easier to make 16 changes manually. _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
