Leonardo hangs up after tone() #960

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Leonardo only.

Once executing tone() function, Leonardo hangs up. Leonardo will not accept 
further upload of sketch. Hardware reset is needed to exit this situation.

This problem is because ATmega32U4 doesn't have TIMER2.

I have just purchased an Arduino Leonardo and have tried the "fix" above and 
the board still locks up when trying to use the tone command.

Same for me! Leonardo board hangs up wile starting up Tone() sketch.
But you can try http://arduino.cc/playground/Main/LibraryList#Audio if you need 
some audio output!
Alternative libraries are working as they should.

Also, I moved the timer 2 #undef's to pins_arduino.h (which is #included by 
Arduino.h):
