Wow...
Just wow. If that's what it is, I hang my head in shame! That's the code I was sending, copy/pasted out and all...
And I checked that I had the right several times, but somehow I think I got the abbreviations backwards, and was explicitly checking that I had it saying scl, because I was convinced that was what it was.
Very expensive error - over 5 hours of time spent debugging this. I was going crazy, doing things like ohming out the wires, checking every combination of pins for shorts, etc. Had it not been for this, I'd have two more modules tested and submitted, plus more sleep.
