I was able to create an alternative heading vector using the atan2() equation mentioned in the last section of that document. For people in future world, just plug in your mg values for x, y, and z where it uses Gx, Gy, and Gz respectively.This will ...

Thank you. Are you getting the huge degree error towards 90 degrees though?The problem is the logarithmic nature of how I'm deriving degrees. I am taking arcsin of g to get radians, and then multiplying by 180/pi ( 57.3 ). After 75 degrees, the outpu...

Hey Niccolo.Thanks for looking into this. You know, I was aware of the 30mg error, but I am just realizing that that 30mg accounts for the last 15 degrees. As insane as this is, technically, the readings are within spec. My algorithm is solid. What y...

Hi Federica,I have the following config:CNTRL_1_A = 0x11 0001 - 14 bit High Resolution 0001 - BDU bit set (block data update)CNTRL_2_A = 0x04 00000100 - Rolling Read EnabledThe last three registers are 0x00 (default).I have this same configuration ...

Kosta,I've had issues like this a few times. Sometimes the part is not soldered correctly. Other times the part is not configured correctly. Do you have a logic analyzer you can use to confirm the device is being configured? It is imperative to read ...
