Artoo Adaptor For Digispark

This repository contains the Artoo (http://artoo.io/) adaptor for the Digispark (http://www.kickstarter.com/projects/digistump/digispark-the-tiny-arduino-enabled-usb-dev-board) ATTiny-based USB development board with the Little Wire (http://littlewire.cc/) protocol firmware installed.

Artoo is a open source micro-framework for robotics using Ruby.

For more information abut Artoo, check out our repo at https://github.com/hybridgroup/artoo

This gem makes extensive use of the littlewire.rb gem (https://github.com/Bluebie/littlewire.rb) thanks to @Bluebie

Installing

gem install artoo-digispark

Using

connection :digispark, :adaptor => :littlewire, :vendor => 0x1781, :product => 0x0c9f
device :board, :driver => :device_info
device :led, :driver => :led, :pin => 1

work do
  puts "Firmware name: #{board.firmware_name}"
  puts "Firmware version: #{board.version}"

  every 1.second do
    led.toggle
  end
end

Connecting to Digispark

Connecting to the Digispark (http://www.kickstarter.com/projects/digistump/digispark-the-tiny-arduino-enabled-usb-dev-board) ATTiny-based USB development board is very easy using Artoo, first we need to install the littlewire (http://littlewire.cc/) protocol to communicate with the digispark, Artoo includes CLI commands to make the process of uploading littlewire to the digispark as simple as possible, after littlewire has been uploaded you can connect and communicate using Artoo.

OSX

The main steps are:

Install the artoo-digispark gem
Upload the Littlewire protocol to the digispark
Connect to the device via Artoo

DO NOT plug in the Digispark to your computer's USB port until prompted.

Install the artoo-digispark gem:

$ gem install artoo-digispark

After installing the artoo-digispark gem run the following command to upload littlewire to the digispark, plug it to a USB port when prompted:

$ artoo littlewire upload

Once plugged in, use the artoo connect scan command with the -t usb option to verify your connection info:

$ artoo connect scan -t usb

Now use the ID info returned to find the product and vendor ID's required to establish a connection with the Digispark in your Artoo code.

That is it, you are set to start running Artoo digispark examples.

Ubuntu

The main steps are:

Install the artoo-digispark gem
Add a udev rule to allow access to the Digispark device (Do not worry about this, the artoo littlewire upload command does it for you if none is detected)
Plug in the Digispark to the USB port
Connect to the device via Artoo

DO NOT plug in the Digispark to your computer's USB port until prompted.

Install the artoo-digispark gem:

$ gem install artoo-digispark

After installing the artoo-digispark gem run the following command to upload littlewire to the digispark, plug it to a USB port when prompted, you might be asked to enter your sudo password, since uploading littlewire to the digispark requires some new udev rules, you can check and review them in /etc/udev/rules.d/49-micronucleus.rules after running the artoo littlewire upload command):

$ artoo littlewire upload

Once plugged in, use the artoo connect scan command with the -t usb option to verify your connection info:

$ artoo connect scan -t usb

Now use the ID info returned to find the product and vendor ID's required to establish a connection with the Digispark in your Artoo code.

That is it, you are set to start running Artoo digispark examples.

Thanks to @bluebie for the help with udev rules used when uploading littlewire to the digispark! (https://github.com/Bluebie/micronucleus-t85/wiki/Ubuntu-Linux)
