Draw2D with Node.js backend
It is just about 40 lines of server side code to connect draw2d with node.js and load/save JSON files or have access to the RaspberryPI GIO ports. Just checkkout the sample application on GitHub: https://github.com/freegroup/draw2d_js.app.brainbox or install this application with npm if you have already installed node.js
bash: npm install -g brainbox
you can now start the server with
brainbox. This works well even on you RaspberryPi. You have full access to your GPIO pins fro the circuit simulator in your browser!
