You might keep in mind the GEVCU project which can be purchased from EVTV ( http://store.evtv.me/proddetail.php?prod=gevcu&cat=23) It is open source and has enough I/O to do what you want. Of course, what you want is rather custom so some coding would have to be done. But, the nasty low-level stuff would already be done for you. Currently it works with DMOC645, Brusa, and Coda UQM controllers. More devices are being added every so often.
It's in the spirit of Arduino and, full disclosure, I helped make it.
