This software aims to turn your GNU/Linux machine into an Android Accessory. It initializes any Android device connected via USB as detailed on Android website: http://source.android.com/tech/accessories/aoap/aoa.html
As of today (alpha v0.3), autotools have not been configured. Therefore the build is done manually as follow:
$> make
This software requires the use of libusb and libasound.
For cross-compiling, several environment variables must be set manually:
$> export ARCH=arm
$> export CROSS_COMPILE=<custom_toolchain>
$> export CFLAGS="-I<path_to_libusb_headers> -I<path_to_libasound_headers>"
$> export LDFLAGS="-L<path_to_libusb> -L<path_to_libasound>"
$> make
Before connecting the device execute next command to remember the current list of USB devices:
$> ADK_DEVICE=$(lsusb)
Then, plug in your Android device and make sure it is unlocked.
The following command will compare two lists of USB devices and show the difference:
$> diff <(echo $ADK_DEVICE) <(lsusb)
Take product and vendor IDs of your USB device from the output as <vendor:product> like this one "18d1:4e42".
Run linux-adk as FTDI GPIO accessory:
$> ./linux-adk -d <vendor:product> -M "FTDIGPIODemo" -m "FTDI" -n 1.0
In the standard output you will see all the data received from the Android device.
Android app and more detailed information about this example you can find in android-accessory-bootstrap repository.
