Help with back buttons

[yaniv]

Hello.. Just finished guide 4! Thanks wermy! One thing I think I messed up is the left right trigger. I wired them up to the teensy 10/11 but I'm not seeing any output (I am for all the other buttons). It's all already glued and a major pain in the butt to get out, just wondering if there is anything else I could check before I unglue it all and check the contacts again? I messed up the mini usb board and fixing that one up took a lot of time and patience

Unfortunately, you will need access to the terminals to test them with a multimeter. If all other buttons are working though on your teensy, sounds like either a soldering problem or a bad tactile (x2). Likely you have your connections wrong.

Thanks! Finally got around to testing this. I checked the continuity with a multimeter, before going and ungluing stuff. Everything seems to be soldered correctly. How should I be soldering to the teensy i.e. there are 3 wires, but only 10/11 on the teensy, where does #3 go at this stage in the process? Thanks!

All your buttons need to be connected to the same ground
You can solder the "third wire" directly on the ground you allready used on the teensy or if it's more convinient for you, on the controller PCB somewhere on your shared ground.

Duh! That makes sense I'll give that a try and report back.. Thank you!
