HMC6343 Datasheet, PDF (13/13 Pages) Honeywell Solid State Electronics Center – 3-Axis Digital Compass Module

HMC6343
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 5 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
Roll Byte pairs; binary format in tenths of a degree with 2’s compliment on pitch and roll angles. (0 to 3600
heading, ±1800 pitch, and ±1800 roll)
6. Repeat the 0x33 sends and six Byte clock backs every 200 milli-seconds or longer to get fresh data from the
default 5Hz update rate.
