I'd be interested in trying it out. I'm using the Teensy platform ( http://pjrc.com/teensy/index.html) but it's worked out very well for every other library I've used with it so problems should be minimal or non existent. let me know if you want my help -Eric On Thu, Jun 18, 2015 at 7:32 PM,

National Instruments (and may other vendors of software) has apparently cottoned on to the fact that if they don't start catering to the Maker market (I hate that term) that they will get left behind. In that spirit they have released a non-commercial licence of labview. you can learn more about
