Trying to interface via USB to Android
Closed this issue · 5 comments
Dear Akagawa-san,
I found your library here, and hoped you might help me with my research. I am trying to connect an existing touch screen device which is implemented as an HID multi-touch class device to Android. The device currently works well with Windows and Linux, but does not work with Android.
I wonder if it has to be implemented using AOA2 and being a host rather than a device to work.
I was thinking of implementing an Arduino based AOA compatible interface for this, and wonder if your library should be used with the USB Host shield, or can it also be used with the Arduino Mega ADK (http://arduino.cc/en/Main/ArduinoBoardMegaADK?from=Main.ArduinoBoardADK).
thanks a lot!

If your device supports AOA, it's right. I think the advantages of using AOA are power supply.
If use with Yaoadk(https://github.com/ADKstudyGroupTokyo/Yaoadk), you can support various Arduino boards.
thanks!
is it possible to implement HID device with AOA not requiring an Android app to be launched but rather affecting the whole UI of all applications? My device is a touch screen, so it is supposed to work for all apps.
Possibly. But I don't know detailed spec.
My device is mouse only.

AOA2 document is only this. Too less.

Dear Akagawa-san,
I have a question.Do you plug in mouse into the android phone can be use?
Don't install app?
thanks a lot!
Of course !
If your Android phone is supports USB Host, not required any apps.

HID over AOA2 and USB Host HID is same function.
But direction of the power supply is the opposite.
- USB Host : phone to mouse
- AOA : mouse to phone
