Cylon.js For Digispark

Cylon.js (http://cylonjs.com) is a JavaScript framework for robotics and physical computing using Node.js

This repository contains the Cylon adaptor for the Digispark ATTiny-based USB development board with the Little Wire protocol firmware installed.

How to Install

Installing the cylon-digispark requires the libusb package already be installed.

OSX

To install libusb on OSX using Homebrew:

$ brew install libusb

Ubuntu

To install libusb on linux:

$ sudo apt-get install libusb-dev

Windows

No instructions yet...

Installing

Now you can install the module with:

$ npm install cylon cylon-digispark

If you're experiencing the AttributeError: 'module' object has no attribute 'script_main' build issue, then please refer to this comment

How to Use

This small program lets you toggle an LED on and off.

var Cylon = require('cylon');

Cylon.robot({
  connections: {
    digispark: { adaptor: 'digispark' }
  },

  devices: {
    led: { driver: 'led', pin: 2 }
  },

  work: function(my) {
    every((1).seconds(), function() { my.led.toggle() });
  }
}).start();

How to Connect

Upload the Littlewire Firmware to the Digispark

Connecting to the Digispark ATTiny-based USB development board is very easy using Cylon, first we need to install the littlewire protocol to communicate with the digispark, Cylon 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 Cylon.

OSX

IMPORTANT: 2012 MBP The USB ports on the 2012 MBPs (Retina and non) cause issues due to their USB3 controllers, currently the best work around is to use a cheap USB hub (non USB3) - we are working on future solutions. The hub on a Cinema display will work as well.

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

Install the cylon-digispark module:

$ npm install cylon-digispark

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

$ gort digispark upload

Once plugged in, use the cylon scan usb command to verify your connection info:

$ gort scan 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 Cylon code.

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

Ubuntu

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

Install the cylon-digispark npm module:

$ npm install cylon-digispark

After installing the cylon-digispark module 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 gort digispark set-udev-rules command:

$ gort digispark upload

Once plugged in, use the cylon scan usb command to verify your connection info:

$ gort scan 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 cylon code.

That is it, you are set to start running Cylon 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)

Windows

We are currently working on docs and instructions for Windows. Please check back soon!
