This is an Arduino library for Grove - 3-Axis Digital Compass HMC5883L from Seeed Studio.
Values of x, y and z read from the compass seem to have offsets. To calculate the offsets, rotate the compass to get minimum and maximum of x, y, and z.
offset = (minimum + maxmum) / 2
value = valueRaw - offset
