The GS3 and the Nexus 7 can both recognize the Due with ADK 2012, I've tested with both. Are you running a custom ROM or kernel?  Perhaps one that leaves out USB accessory mode?

I use stock rom with rooted.
The GS3/Nexus 7 recognized the Due as "connected to a USB accessory". But ADK 2012 couldn't recognize the Due.
Connection:
PC-->USB Cable-->Programming Port on Due
Nexus 7/GS3-->USB Cable-->OTG-->Native Port on Due.

In that case it must be the way the Due is representing itself.  What sketch have you loaded on the Due?

ADK 2012 should recognize the Due on Nexus 7. But waited a long time more than 5 minutes, ADK 2012 could not start correctly, it was forced stopped.
GS3 still could not recoginze the Due. I have loaded the sketch from Ardroid on this post.

ADK2012 is looking for a specific device, namely the ADK demo board that they handed out at I/O.  The device identifies itself by sending strings to android.  If you use the constants in the example from mikepparks, adk2012 should "see" the board... although of course none of the testing features will work by default since none of those circuits exist (unless you put them there).

Hi all,
I just confirmed upload of modified ADK2012 to DUE on both Mac and Win in my desk.
Mac:
 Macbook Pro 10.6 with JDK 6 DUE: program port
Win:
 Windows7 64bit   DUE: native port (BOSSA Program port (COM**))
Thanks to aleu and jamgofei and all.

Why don't the mac/windows tools use the same port for programming?

they do.  rather, they can.  This is just how he did it.

I have my Due working with sound from a Galaxy Nexus but the quality is pretty poor. I put a 1KHz tone on my phone and played it through the Due and it quickly becomes apparent that there is something wrong. There are gaps in the audio which don't seem to be periodic. On the scope I see small gaps about a millisecond long. The gaps happen about every 100msec (or so). After the gap, the output continues at the same voltage which makes me think the dac might be sending the same value during the gap until more data is available. Anyone else observe this?

Can you control volume when audio out via Due?  I could not adjust volume when output audio via Due.

[Reply #38 on:]

The volume over the usb seems to be fixed but there is a line in the code on Due that claims to be a volume adjustment; after combining the left and right channel, they multiply by a value and the comment is something about volume adjustment.

Great! I have the following questions:

1. Which Arduino IDE do you use? arduino-1.5.1r2? or adk2012_ide-win32-20120629?
2. What app do you use on Nexus 7 to transfer data to Due?
3. Is DC to supply power a must? Arduino Due can't work when I use a DC--3.3V & 2.0A. What DC do you use?

1. Used ADK2012 IDE from Google
2. This Terminal App,  http://labs.arduino.cc/uploads/ADK/ArduinoTerminal/ThibaultTerminal_ICS_0001.apk
3. You can use computer's USB power and I've tested 12V DC external power also. It works either way. (Arduino DUE has some issue with USBVSB (USB Master power control) That's why usbh.c needs to updated to work properly on DUE.

When use ADK2012 IDE for Due, do you copy board definition from Arduino IDE 1.5.1 to ADK2012 IDE? Since pin array of Arduino Due is different from Google ADK2. For example, Blink sketch will not blink LED if you choose board Google ADK2, because Google ADK2 define PC9 as pin 13, Arduino Due use PB27 as pin 13. I copy directory hardware/arduino/sam/variants/arduino_due_x from Arduino IDE 1.5.2 to ADK2012 IDE and select it as board, but some errors happen during compiling. Do you know have any idea or experience about this issues? Thanks.

I am in the same boat as lier. Can someone describe the process for compiling and uploading sketches from the ADK 2012 IDE to the Due? Uploading from Arduino IDE works fine for me but not the ADK.

Hi,

I am trying the ADK2012 code on Due and facing the following Compiling Error. I saw someone mention the problem, but could not find a way to resolve it.
