Magnetic flux

I have been playing with the magnetometer in the Pololu 9DOF IMU. I recorded the data into a CSV file and plotted it in Excel. At the time I did not think much about it, but one evening as i … Continue reading

AS3935 and register zero

The more I bang my head against this chip, the more I am certain there are ‘issues’ with it. I can now read and write every register with amazing repeatability except register zero. This register refuses to be read or … Continue reading
