I have wrapped up the code that comes with this FM receiver from Sparkfun into a library.
I also took the opportunity to tidy things up a bit and fix the RDS.
Help yourselves....

Its a nice little module. The only downside is that its 3.3V. But I decided to use a Ardweeny with it running at 3.3V. Schematic attached for anyone interested.
Yes indeed - its at the bredboard stage ATM - but all working, I just need to move it onto stripboard.
Incidentally the circuit above is not quite right, R4 should go to 5V not GND.
Also I will swap a few pins round for more convenient layout.
