Tim Marvin / Mbed 2 deprecated DataLogger

Data logger for my IMU Board. Writes a time stamp in seconds, 3 accel values in G\\\'s, and 3 gyro values in radians/sec to the SD card. Uncomment one one to add Magnetometer values. Records for 60 seconds. Change on line 55 if necessary. Updates LEDs to display status such as opening and closing file, and errors.Also supports SD cards up to 32GB (SDHC)

Dependencies:   mbed ITG3200_lib
