Hi everyone,
First, I need to say that I've been a silent reader for months, and enjoyed it a lot. Thanks you guys!
Now, for the issue at hand: last Friday, I received my kit from the second Massdrop batch (hapiness). I'm almost done with the assembly, all that's left for me it to solder the keyswitches on the right hand. However, I'll need help troubleshooting things. So far, I haven't read about anyone facing the same issue, so I'll try to be specific. I wanted to test the left side of the keyboard because every component is already in place (except for the keyswitches on the right side, as noted above). However, the keyboard does not register any keypress. Here is what I confirmed to work:
- initially, the teensy USB was blinking
- I can load a qwerty-keyboard (from the massdrop configurator) with no trouble
- I can confirm that the right hand side of the keyboard register keypress when creating a short with a wire.
- no keypress from the left side are registered (pressing a keyswitch or creating a short with a wire)
It seems pretty hard to find out what wrong on the left side, and I have no clue. I tried melting some solders in case of a cold joint. I can't seem to find any part where the circuit would be broken. All the SMD, the I/O expender seems to be correctly oriented (I'll double check that). Perhaps a faulty cable, but that would be surprising.
Any thoughts, insights or similar experience?
Regards,
Shad
