I have the mechanical portion of my servo driven telescope mount almost finished so it is time to start messing with the controller for it. I plan on using OnStep, an arduino based controller here:

Firmware here (remove "-experimental" from the folder name and open the OnStep.ino):
https://github.com/hjd1964/OnStep
The arduino sketch was intended to run on an Arduino 2560 but I would really like to use a Teensy 3.1, I am hoping to get a higher step pulse rate than what he is getting since my motors are much higher resolution than his. He had some timing issues from the serial port so there are direct register calls bypassing the arduino stuff.
There are three sections that need modification, the main OnStep.ino, Serial.ino, and Timer.ino. They all directly access the serial port and timers. How do I change it to work with the Arm?
