wiring grounds from switches

[tempus]

Hey all;

I'm about to actually build my pedalboard router. I have 14 momentary contact switches, each of which will ground one pin of a PIC uController. I was wondering about the best way to connect the grounds. Should I:

1. send a separate wire to ground on the  circuit board from each switch,
2. connect all the switches together (one side only) and send only 1 wire to the ground on the board?

Since either method avoids ground loops, I suspect it doesn't really matter, but if there's a chance one way might somehow induce switching noise or cause some other problem, I want to head that off before it becomes an issue.


Thanks

I'm pretty sure that since you're talking logic states, unless you get REALLY sloppy, you're fine with daisy-chaining the Gnd connection for each switch. It's either up or its down.
