Folks,
I posted on this topic before, regarding a Temperature/Humidity sensor I purchased from Adafruit- the AM2315. I have since learned some interesting new things. For one, the problem that I am having appears only on the Teensy 2.0, but not on my Teensy 3.0.

for some historical information.
The thing that is killing me here is that the problem appears with the Teensy 2.0 (standard 5V config), but not the 3.0. I am using v1.03 of the Teensyduino IDE.
The fact that the bad data follows changes in humidity makes me think it might be a timing issue. What are the differences between Teensy 2.0 and 3.0 that could account for such a difference?
(btw, Thanks Paul, for your recent reply to my AFI post. I will look at the library and take your suggestion)
