I have a HMC5883L 3-axis magnetometer. I would like to add tilt compensation to my Arduino Uno project.
Since the IC has 3 axis that it measures (X,Y,Z) is it possible to add tilt compensation without an accelerometer? If yes would this how do I find an equation to do the calculation. Is this equation found from http://bluelemonlabs.blogspot.fi/2013/08/arduino-simple-compass-with-hmc5883l.html correct?
