i'm trying to communicate with Arduino board (Duemilanove) from Android 3.1 device with USB-host support using Android USB Host API.
The goal is to communicate with the board in the same way as via Serial.
I follow this manual (http://android.serverbox.ch/?p=427
) but have few problems (f.e. failed to claim interface) and of coarse dev guide (http://developer.android.com/reference/android/hardware/usb/package-summary.html
) but no luck.
The questions are:
1. how to prepare arduino board (modify firmware) - interruptions or smth?
2. how to check if it's okay with arduino board (f.e. enumerate USB interfaces and verify that it supports needed. what tools can be used?
3. how to find needed interface (what are interface class/protocol/subclass)
4. what can be the reason when interface cannot be claimed? (faced with that)
Thanks in advance
