Using Interrupts with Node.js on Galileo

Hi All After reading the announcement of the new XDK IoT development environment (IDE?) that uses node.js I have been trying to see what it can do. After a bit of refresher/learning about node.js/javascript (since only used a little with HTML a long time ago) I started to do some experiements. After a bit of a shock/learning curve at creating a program where each function runs in its own thread, so at the same time instead of in sequence as I am used to, I have gotten a motor controller board, sort of working. (PWM isn't working yet) The next thing I would like to try is to see if it is possible to use hardware interrupts to count wheel rotations (yes I know the timing isn't like an Arduino, but would like to see if can work.) So can anyone give me a hint on how to have a program written in node.js check for hardware interrupts? Thanks rgb

Since this has been unanswered for a long time and I have seen the same question on another board, also unanswered, I guess that there isn't any way to do it. It seems might be possible under Python, but not node.js Whoever is moderating can delete this entry. thanks rgb

If this approach solves your issue, then you can use setInterval function in Node.js and call your handler.
