Hi, due to an incompatibility with my current program, I can not use the Tone library to play RTTL files, is there another library in which I can do this?
What is RTTL/RTTTL?
What hardware, and what is the incompatibility?
@dwjp90: Good point - the RTTTL sketch needs to work with the tone() function - it's a simple change, so here it is:
// A fun sketch to demonstrate the use of the tone() function written by Brett Hagman.
// This plays RTTTL (RingTone Text Transfer Language) songs using the
// now built-in tone() command in Wiring and Arduino.
// Written by Brett Hagman
// http://www.roguerobotics.com/
// To play the output on a small speaker (i.e. 8 Ohms or higher), simply use
// a 1K Ohm resistor from the output pin to the speaker, and connect the other
// side of the speaker to ground.
// You can get more RTTTL songs from
// http://code.google.com/p/rogue-code/wiki/ToneLibraryDocumentation
const int tonePin = 27; // for rEDI board
//const int tonePin = 13; // arbitrary for arduino boards, set this to whatever you want
#define OCTAVE_OFFSET 0
// These values can also be found as constants in the Tone library (Tone.h)

Sorry for the delay in replying.
The incompatibility is with a LCD/touchscreen on an Arduino mega (both models)
Having the sound library (just the RTTTL pde in a library) causes garbage to be displayed on the screen.
I just did a test, and having tone(13, 600); in the pde will not cause garbage.
Having the RTTTL library active will cause garbage on the screen.

Hi, due to an incompatibility with my current program, I can not use the Tone library to play RTTL files, is there another library in which I can do this?
If there's a timer 2 compatibility issue and as a result you can't use the tone library, you can instead use my NewTone library which uses timer 1 instead. NewTone is a drop-in replacement for tone so it would be very simple to impliment.
Another option (and maybe a better one) would be to use my toneAC library which also uses timer 1 and has many other benefits (twice as loud, uses fewer cpu cycles, more accurate, etc.). It's not designed to be a drop-in replacement, and you would be limited to using specific pins for driving the speaker. But, with very little effort you would have technically a better solution. If nothing else, it would be louder (or allow you to control the volume).
