UltraStik 360 New Feature Release: Shift Function

Ok, then maybe I'm not on the right track.

I thought that could use the 7 dedicated pins for their buttons by only being connected to the ground wire, and the numbered pin. (normal button setup)

Then I thought I could use the other 7 buttons by connecting them to both the 8th pin (shift) and a numbered pin 1-7 plus the ground.  These buttons would basically be sending button 8(shift) + the other pin.  I was thinking that this would eliminate the need for an actual 8th button to be used as shift.

The buttons would correspond to pins 1-7 individually, then 8&1, 8&2, 8&3...etc to 8&7...for 14 buttons total.

Maybe I'm not explaining it clear enough?

I think you have it right.  The only way to be sure is to test it out.  Randy's Shazam button can work that way but he has some special wiring harnes.  It includes diodes but I am not sure what the purpose is.  Here is a link to the special diagrams for the KeyWiz  I am guessing that you would need to use a simular wiring setup for your plan.

Er.. no. If you think about it, and look at your diagrams, what you have done is connected all the pins together which is definitely not what you want to do! There is a path from each pin, via the shift pin to every other pin.
This kind of arrangement can be made to work actually but you do need to use diodes and its probably not worth the hassle, but if you want to have a go, drop me an email and I'll help.
