Several Questions about the LIS3MDL

Question asked by yeh.peihsun on Feb 12, 2015
1. On page 6, where it shows the orientation of the axis, does the arrow point in a way such that I should get positive readings by pointing them towards magnetic North? More specifically, what calibration procedure should I follow? I found this post, but what would really help is a step by step to find magnetic North: https://my.st.com/public/STe2ecommunities/mems_sensors/Lists/eCompasses/Flat.aspx?RootFolder=https%3a%2f%2fmy%2est%2ecom%2fpublic%2fSTe2ecommunities%2fmems_sensors%2fLists%2feCompasses%2fLIS3MDL%20offset&FolderCTID=0x01200200770978C69A1141439FE559EB459D75800050C48E6E10688F4B961EEC4647FF3FE1&currentviews=94. Thanks, never used a magnetometer before. 


2. How is the DRDY (Data Ready) interrupt pin operate? How do I set/clear it? And do the threshold registers have any affect on DRDY?

3. Not a question, but the register address map on page 23 has the INT_CFG register labeled as a second STATUS_REG.
