Using Ardupilot for vibration survey - increase IMU-sampling rate - Discussions

Hi Sven,

I too felt the need to measure/profile vibration as well as magnetic flux related characteristics of motors, etc... I wanted to leverage "off-the-shelf" flight controllers without modifying the flight controller software. That being said, I currently use a multiwii flight controller and the multiwii protocol for accessing sensor data. I can get approximately 30hz sample rates using this approach. Here's a photo of my test environment that consists of a vibration plate with an a motor and a flight controller mounted to it along with some custom software.

I've been satisfied with performance and it's allowed me to define a set of benchmarks/tolerances for various motors prior to mounting them to a multirotor. I'm interested to hear what you find with respect to using the APM or other as sensor array.
