Nathan Ewin / Mbed 2 deprecated LogData_UM6-to-SDcard

A project similar to http://mbed.org/users/lhiggs/code/UM6_IMU_AHRS_2012/, where I'm trying to log data from a UM6 (CH Robotics orientation sensor) and a GPS transceiver to an sd card. I've adapted LHiggs code to include ModGPS. For sum reason a soon as I pick up a gps signal the UM6 data freezes i.e. the time and gps signals continue to print out but the UM6 signals fixes on a single value.

Dependencies:   MODGPS MODSERIAL SDFileSystem mbed
