I2C Compass Module Driver


I have posted a driver for the Honewell HMC 6352I2C Compass module on


Good lad… Is this the driver from the projects page… or a completely new one.

Cheers Ian


No, this is one I wrote. I did look at the one on the project page for a hint of how to calculate the heading. I do intend to extend this to include the other functions and modes of the chip in the near future.


I have on of these in my indicator. It works extremely well I thought

Cheers Ian


I have updated the code on Fezzer to include commands for operational modes, reading and writing eeprom, and several other commands.
