recently i use the magnetometer mag3110, i have read the correct data from the sensor. but how i use these datas effectivly? i want to calculate the angle. but i even don`t know what`s the angle really mean as the sensor`s data and how to calculate. so can someone help me?
Hi Mandy,
I would recommend you to take a closer at my example code where I illustrate a very simple technique to calculate compass heading using the atan2() function.
For a more complex tilt and interference-compensated e-compass, please refer to this article, AN4248 and E-Compass Software|NXP.
Hope it helps.
Best regards,
Tomas
