Magnetometer compass calculations | Electronics Forum (Circuits ...
2014年10月9日 · I want to calculate a compass heading from a 5883 magnetometer sensor, using x and y readings. To get the heading angle in degrees within a quadrant of 90 degrees I was thinking of: arctan (x/y) (x and y being the magnetometers readings). This gives me an angle within a 90 degree quadrant...
Want to build a magnetometer | Electronics Forum (Circuits, …
2009年7月23日 · Hello, I was watching a TV show on my local PBS station and they used a Magnetometer to locate the remains of structures on an archaeology dig. The device looked very simple compared to other electronic devices used. I have been looking for plans to build a homemade magnetometer, but it seems...

2022年3月28日 · Now measuring with a magnetometer of a cell phone gives me a more or less 50% real value compared to the calculated theoretical value. Measured with tw different phones. You can also see that the substraction (changin the polarity of the input voltage) of the geomagnetic field gives me plus/minus the same value.
Increasing data update rate of MPU9250 | Electronics Forum …
2019年1月22日 · The MPU has magnetometer, acceleromter, gyro, and sensor fused readings. If the compass has no trouble keeping up with a more reasonable turn rate, you might be saturating the gyro and many gyros give false readings when that happens (the output doesn't just saturate at the max angular velocity.
Using MAGMASTER to get compass calibration settings.
2020年8月28日 · Hi, I use AK8963C Compass chips, for projects. These each need calibration values, that are used in programs. I asked a similar question quite a while back, and didn't realise that the answers I followed led me in a the wrong direction. The previous results gave me a …
How to test electric power steering (EPS) for stability on adverse …
2022年12月4日 · Please consider commercial vehicle equipped with EPS ECU and other ECUs such as Antilock brake system (ABS), engine, transmission, Body Control Module (BCM), etc. I would like to come up with tests for testing EPS on adverse road conditions such as wet or icy pavement for vehicle stability...
