How to get Talkie running on Arduino Leonardo

[AndreNeedham]

I recently got an Arduino Leonardo and wanted speech output, so after some fighting with the code, I got Talkie running. (It took longer than it should have due to my trying to fix the PROGMEM const issue by just removing the PROGMEM keyword. Bad idea. Once I fixed that properly things went more smoothly.) I replaced Timer2 with Leonardo's Timer3, and the speaker connects to pin 5 instead of 3.

All changes would be in Talkie.cpp. For myself I just changed the code directly, but for your code something like an "#if defined (ARDUINO_AVR_LEONARDO) / #else / #endif might make the most sense.

Here are the changes in Talkie.cpp:
In Talkie::say(uint8_t* addr):
change:
pinMode(3,OUTPUT);
to:
pinMode(5,OUTPUT);

change:
TCCR2A = _BV(COM2B1) | _BV(WGM21) | _BV(WGM20);
TCCR2B = _BV(CS20);
TIMSK2 = 0;
to:
TCCR3A = _BV(COM3A1) | _BV(WGM30);
TCCR3B = _BV(WGM32) | _BV(CS30);
TIMSK3 = 0;

In ISR(TIMER1_COMPA_vect):
change:
OCR2B = nextPwm;
to:
OCR3A = nextPwm;

That's it. Thanks for creating Talkie!

confirmed this works on mega. thanks!
