I'm working on creating an example set of projects that share a common code base between the 2 different micros. There's a few github projects that I might base it upon but in my own style. With a CLI (Command line interface) to control it, similar to the SplashBase's.
Then add the ultrasonic on top of that as a demo of the codebase.
Booking shipping, hire car, travel arrangements for MakerFaire has taken over at the moment, just hoping our stuff makes it there!
So might not be until next week that I can get back on it.
Until then there's lpxpresso & lpcopen example code linked on the project page.
