That's a great idea, thanks Omer. I'm still learning Clojure and haven't touched ClojureScript yet, but it doesn't sound like it's an overly difficult transition.
Another plus on the ClojureScript side (long term) might be execution speed. I recently watched a Clojure Conj 2012 presentation by Chris Granger where he talks about being able to obtain very good performance (as in 60 frames per second in a game) with ClojureScript: http://www.youtube.com/watch?v=V1Eu9vZaDYw&list=TL6M8RJo7MDr0 On Wednesday, September 4, 2013 10:09:25 AM UTC-4, Omer Iqbal wrote: > > Another possible approach could be use clojurescript to a nodejs target. > From some cursory googling, there do seem to be node modules like > https://github.com/kelly/node-i2c which offer I2C support. > And I believe you might also get a better startup time. > > > On Wed, Sep 4, 2013 at 8:35 PM, Jeremy Wright <wrig...@gmail.com<javascript:> > > wrote: > >> I decided to start with the BeagleBone Black as the embedded controller, >> partly because of the low cost ($45) and partly because I have one on hand. >> So, the first thing I need to do is make sure that I can get the I2C >> interface to work from Clojure. >> >> Gregg Harrington's post might work as a starting point: >> http://www.greggharrington.com/articles/beaglebone-i2c-java-adapter >> >> I'm assuming that I can use Java interop in Clojure to do the same thing. >> I have a Melexis MLX90614 I2C temperature sensor laying around already, so >> I'll try to get data from it with the BeagleBone/Linux/Java/Clojure stack >> first.
