Hi!

I just had a relatively easy success (2 evenings) getting the Teensy to play nicely with this OLED display:

I had to change very few little things in adafruit's library (most of them described in this thread) but it's working beautifully now. I used the provided Wire library though.

Another thing is that I crafted this Rakefile to compile and install:

It's based on the Makefile available as part of the Teensy install, but I also added support for Arduino libraries and project-only libraries. Whenever I have the time, I'll create a starting project including the Rakefile to github, in case that's useful for anyone.

Thanks! I'm having lots of fun! ^_^
