I'm using an Arduino Mega board, and am incorporating the Tone.h library to play two tones simultaneously (see the "Ugly Details" section): http://code.google.com/p/rogue-code/wiki/ToneLibraryDocumentation
I've implemented the code on the Duemilanove without an issue, with timers 1 and 2 being "used up" as a consequence.
However, I was wondering which timers will be "used up" with the same code applied on the Arduino Mega, and which PWM pins will no longer be usable as a result.
I found this site to be somewhat helpful, but wasn't able to determine which timers will be used: http://softsolder.com/2010/09/05/arduino-mega-1280-pwm-to-timer-assignment/
Any help would be greatly appreciated. Thanks in advance!
