Auduino not working on Arduino Mega2560

[GoogleCodeExporter]

Not functioning on Mega2560.

Suspect the Mega1280 conditionals need extending to Mega2560 devices.

I can confirm the bug and proposed fix.

I've changed line 34 of DmxSimple.cpp to:

#if defined(__AVR_ATmega168__) || defined(__AVR_ATmega168P__) || 
defined(__AVR_ATmega328P__) || defined(__AVR_ATmega1280__) || 
defined(__AVR_ATmega2560__)

It now works on the my Mega 2560.

I'm kinda confused...is DmxSimple.cpp used with the Auduino?

Apologies.  I thought this 'issue' was with an arduino library called 
"DmxSimple".  This bug tracking system doesn't make it obvious which 
project/product a bug is raised against.

Hopefully the reporter, cathed... can clarify?

Any chance you would wanna try to debug the problem we are having here with the 
audio on mega2560? LOL can't blame me for trying!

Any news about this issue?

I just altered lines with

#..if defined(__AVR_ATmega1280__)

to also include the 256:

#..if defined(__AVR_ATmega1280__) || defined(__AVR_ATmega2560__)

Adding the 256 to the conditionals seems to be sufficient b/c of the 
similarities between architectures.

I also altered the lines as said by #6 above. The LED now blinks but no sound 
output at all. Arduino UNO R3 works, but I need to use Mega 2560 R3.

Any suggestions?

Thanks in advance.

I also tried changing the line as per comment #6, with no success... has this 
ever been resolved?

Davidmic's suggestion worked for me on my Arduino mega 2560 R3

I just altered lines with

#..if defined(__AVR_ATmega1280__)

to also include the 256:

#..if defined(__AVR_ATmega1280__) || defined(__AVR_ATmega2560__)

Make sure you're wiring this up properly,

Auduino uses 5 controls. You can use anything that generates a 0-5V analogue 
signal, but the prototype uses five 4.7Kohm linear potentiometers. Connect one 
side of each potentiometer to GND. Connect the other side to the 5V pin on 
Arduino. Connect the middle (wiper) pins to Analog inputs 0 to 4 on the Arduino.

The audio comes out of PWM (Mega 2560) pin 3 (or pin 11 on ATmega8 Arduinos). 
The prototype uses a 1/4" jack socket, with the tip connected to pin 3 (or 11 
on ATmega8's) and the shield connected to GND. Plug the other end into an audio 
amplifier, and you're good to go.

The Arduino can drive a small piezo, speaker or headphones directly. Strictly 
speaking it outputs at 5V rather than the 1V line level, but most amplifiers 
don't seem to mind.

/try adding this line to the top of the sketch"
#include <arduino.h>
"

hi, I had the same problem. I solved using this fixed library for 2560:
