Hi, we are having problems with our BNO055,
Our MCU is STM32F072CBU6\QFN50P700X700X80-49
work under NDoF
There are abnormal spikes even if the sensor is putting still and not moving. However, when the sensors are moving, there are much more spikes.
I understand there were similar problems spoted by other users. but ours seem more serious. Our circuit is blow
yes， it is new. Any idea where might be wrong?
We did a few more tests in recent couple of days.
1) we confirmed that if the sensor stays still (not moving), the number of spikes were significantly reduced. When it is moving, there are much more spikes there.
2) we tried remove the battery, and instead using the USB to supply power. The number of spikes were reduced (see figures below). Our guess is that something might go wrong with power supply circuit. But we re-examine our circuit design, we cannot find any wrong-doing. Could you help us to check it ? (we posted our circuit design)
