command is issued. The first rotation can also be done by rotating 360 degrees about X (Fore -Aft) axis. Then exit
calibration.
The calibration routine collects these readings to correct for hard-iron distortions of the magnetic field. These hard-iron
effects are due to magnetized materials nearby the HMC6343 part that in a fixed position with respect to the end user
platform. An example would be the magnetized chassis or engine block of a vehicle in which the compass is mounted
onto. Upon exiting the calibration mode, the resulting magnetometer offsets are updated.
Example Communication
For basic power up and compassing using the defaults, the flowing order of operations is recommended:

1. Apply power to the VDD pins (nominally +3.3 volts)
2. Wait at least 500 milli-seconds for device initialization. The HMC6343 is in the default Run Mode.
3. Send 0x32 and 0x50 to command the Heading and Tilt Data to be clocked out next.
4. Wait at least 1 milli-second to allow the HMC6343 to process the command.
5. Send 0x33 and clock back six more response Bytes from the HMC6343. These will be the Heading, Pitch and
6. Repeat steps 3 - 5 every 200 milli-seconds or longer to get fresh data from the default 5Hz update rate.
Roll Byte pairs; binary format in tenths of a degree with 2’s compliment on pitch and roll angles. (0 to 3600
heading, ±900 pitch, and ±900 roll)
