Arduino Mega ADK and Sony Erricson Xperia Mini Pro X17i works (well sort off!)

Well After all the banging, thumping and moaning I have managed to get the Xperia Mini Pro X17i to communicate with the Arduino Mega ADK!

First was patching of the Arduino code aka firmware, that took a lot of work mostly due to running the 1.0.1 version of the Arduino  programming environment. After editing loads of it then replacing the Google ADK files with the ones from I got the code to compile and upload but still couldn’t get the Xperia Mini Pro X17i to recognize it (well the phone charged but that’s it) I hit on an idea of using the Xperia live dock!
Powering everything up (mega using separate adapter) I connected the phone to the dock and “Unsupported accessory” message popped up, Yes its at least reading it in the liveware manager app.  After looking back through the arduino code I found the answer in AndroidAccessory.cpp

The following lines

#define USB_ACCESSORY_VENDOR_ID         0x18D1
#define USB_ACCESSORY_PRODUCT_ID        0x2D00

Needed to be changed but to what I hear you ask? The VENDOR_ID and PRODUCT_ID are incorrect (this is stated but I just ignored it causing some of the grief) After a bit of google I worked out how to get my ID code in Windows 7.

Once I had my codes I changed the lines to this

#define USB_ACCESSORY_VENDOR_ID         0x0FCE
#define USB_ACCESSORY_PRODUCT_ID        0×0166

Recompiled and now it’s recognized as Supported Hardware! (This is just for the Sony Erricson Xperia Mini Pro X17i)

Now I need to learn how to modify the Android demo app to make it work!

Note to get the demokit app to work I had to edit the manifest file (see previous file) which solved the errors then I cheated and just suppressed/ignored the warnings and it compiled, unfortunately there a bug in it which is preventing the app from displaying properly or recognizing the board!

I hope this information will be helpfull to you out there also venturing into this field.
