I was trying to get a switch working on the 3rd Digital Input of the drivers station, and I noticed something VERY strange.
I checked all of my connections multiple times, check my switch, tried different wires, different switches, nothing was working. I finally noticed that for some reason whenever I had the PWM end plugged into the 3rd DI port, it acted as a jumper and triggered my code as that input being enabled, regardless of what state the switch was. I unplugged the cable and it went to the default setting.
Just out of curiosity I took a pair of needle nose pliers (I know you guys aren't going to like what I'm about to say) that weren't grounded at all (rubber handle) and touched it to the signal pin of the 3rd input, and SOMEHOW it triggered it, acting again as a jumper.
How could this happen? There's no current or signal flowing from ANYWHERE. My team and I are stumped.
