I've been searching for the better part of the previous evening for a way to connect a em406 directly to the multiwii..
Basically i came to the conclusion that multiwii wont work with a (soft)serial connected NMEA hardware - well, fine for me as it saves me from soldering a socket for the GPS
Later i came to the the conclusion that one way would be to take one of my spare arduinos and "emulate" any of those TWI boards out there connecting the em406 to that arduino and then acting as a TWI device that communicates to the multiwii board.
For that i found https://code.google.com/p/i2c-gps-nav/ but either it lacks any documentation or i simply cant find it..
I wonder if someone here already did that and i couldnt simply find any documentation on such work...
So if someone has some ideas i would be glad to hear them
