I have done the initial port.
I will publish it, later. Probably bitbucket instead of github.
Meanwhile I have attach the new version of the library, which still (should...) continue to work on others platforms.
Update 1: fix a misplaced #ifdef (no effect for RFduino)
Update 2: use TIMER1 instead of TIMER2 I have found, during my test, that TIMER2 is used by Gazell library.
