I want to port a morse code program I wrote for an Arduino Uno to the 32u4. Most of the code won't change excpet maybe pin numbers but I'm using a DDS sine wave generator using the Mega328 timer 2. I used timer 2 because the DDS supersedes the standard Arduino tone(). Grepping around the teensy modifications to the Arduino IDE, I believe tone() in teenseyduino uses timer 3. Is that correct? Timer 0 would port easier because it's 8 bit but will I be stepping on any other functions there?
