Finally getting to wiring up my G1000 V2! I've done a lot of soldering and such before, but reading a full electrical diagram is still sort of new to me so I noticed two things I can't figure out.
It looks like the "Menu 4" button isn't hooked up to any input. It's grounded but there's just a missing digital line.
2. I thought only one arduino mega was needed for this project as there's only 1 mega mount and the photos of other's builds only show one mega, yet the buttons SW1-SW12 (I assume the bottom row of arrow buttons) are all hooked up to U2 Arduino Mega Pro. Does this build require a second arduino? Where are people putting it in your pictures?
Thanks for all your help, everyone! Love this site and all the work you guys have shared!
