Project - G400HDR/G400 using a SD Card module

I just posted G400HDR/G400 using a SD Card module on Codeshare. Feel free to discuss and make suggestions here.

Thank you good idea, at least to use as testbed for the board.
I can’t test now the code on my G400 (I’ve only a mac and G400 doesn’t work on VMware Fusion).
I had best result using sdcard with PersistentStorage and not through Gadgeteer also in a Gadgeteer project.
