ligō is a ruby gem implementing the Android Open Accessory Protocol to interact with Android devices via USB.
Android-side application is needed to make some use of this project. A sample LigoTextDemo Android application is available for usage demonstration.
Just USB I/O using the Android Open Accessory Protocol…
require 'ligo'
id = {
manufacturer: 'Ligo',
model: 'VirtualAccessory',
description: 'PC acts as an accessory!',
version: '0.1',
uri: 'http://blog.renaud.io',
serial: '3678000012345678'
}
Ligo::Logging.configure_logger_output('/tmp/ligo-sample.log')
ctx = Ligo::Context.new
acc = Ligo::Accessory.new(id)
# You could inspect the Android devices list
puts ctx.devices.inspect
# Take the first one
dev = ctx.devices.first
# Switch the Android device to accessory mode
success = dev.attach_accessory(acc)
# then operate on the device (you'll need some Android code for this!)
if success
dev.process do |handle|
# I/O
end
endligō will be nothing without the LIBUSB Ruby binding and the underlying libusb library.
At the time of writing, ligō focuses on the GNU/Linux operating system and YARV/MRI ruby. ligō has been developed and tested on Debian GNU/Linux with ruby 1.9.3p327 and 1.9.3p429.
ligō is useless without Android-side application. A sample LigoTextDemo Android application is available for usage demonstration.
You may install ligō by using:
$ gem install ligo
Or, you can install it from the github repository:
$ git clone https://github.com/r3n4ud/ligo.git
$ cd ligo
$ rake install
- Write the specs and automate testing!
Provide an Android demo application→ See sample LigoTextDemo Android application, more to come soon…- Improve the documentation → in progress, a first pass has been made…
Release and push the gem to rubygems.org- Finalize and publish a celluloid-based write-back usage sample (already working with the sample LigoTextDemo Android application and the libusb 0.3.0 gem async and polling APIs)
- Create a wiki with FAQ, supported devices listing, UMS/accessory interactions, etc.
- Follow the usual fork/branch/PR workflow to send changes, if I like them I'll merge them
- Help me to create a supported device listing
