[DEV][AADK] Google's Arduino based "ADK" Working on Nexus One

---

I managed to snag an Android Accessory Development Kit from Google IO.

After wrangling all the necessary code bits together I got the demo code running on the Arduino board and my Nexus One.

The first picture you can see the phone reading the sensors of the demo shield, button states, the temperature, a light sensor and the joystick position.

In the second picture the phone is controlling the led colors and has one relay turned on.

In the last picture you can see that the phone detects the board being plugged in, Android knows there is no app installed for the board and it cannot be found in market.

The Nexus One is running a rooted 2.3.4 ROM from this thread

P.S. Mod's can we get a forum section for Android Accessory Development?

Now for Pics.

Now that is bad a**!!! I was waiting for something like this!!

Hey, I've been attempting to hack in the support into CM7 (nightly, 2.3.4) on my EVO without much success. I've rebuilt the kernel with the necessary flag enabled and ripped the JAR/XML files from the Nexus S update.

I've monitored logcat and seen that it does find the framework JAR (the application wouldn't install otherwise since it's a needed feature) and a dmesg scan shows that the kernel driver is being initialized.

What's happening now is I plug in the ADK and the output from the Arduino board spams that it couldn't get a protocol version from the phone. The phone slows down to a crawl as its probably being spammed with requests from the ADK for a protocol version and doesn't know what to do.

I'm at a loss here as to what I could possibly be missing. If you have any insight through your own endeavors it would be much appreciated.

Great stuff! I was also at Google I/O and picked up an ADK. Can you post the apk file of your app? I'd love to try it out.

And if you're feeling generous...the code?

badass. good ****

Well done mate...
Have tried it out with arduino UNO?...

uh uh, why i wasn't at the Google I/O
Google is doing really good s**t nowadays. I suppose that Arduino will guest in my house in some time as I am fascinated

I am Actually using the ADK with my Nexus One on an Arduino UNO and an USB-Host Shield from Sparkfun, it works equal but only take a fraction to buy it

My first project is an interface for my Audi, at the moment i only use it to start the Motor, but in future i want to try to build a CAN-BUS interface...

Sure here is the compiled ADK.

The Arduino UNO doesn't have native USB Host support onboard like the megas.
You will need a USB Host shield and will have to modify the Arduino code.
