Jero Posted December 10, 2015 Report Share Posted December 10, 2015 Hello, I have a project, where I want to measure angular changes of a vibrating platform. I want to know, what is happening with platform orientation in very short time window of 20 ms, so i want to get as many values in that time as possible. In specification it says, that 8 KHz sampling can be done by gyro. How much of that is actually achievable and how can I do that? How about DMP values, what is max rate of them? (only yaw, pitch roll) Thank you for any help Jernej Quote Link to comment Share on other sites More sharing options...
dkwill Posted December 10, 2015 Report Share Posted December 10, 2015 Hi- To get the 8KHz sample rate, you set the DLPF to 0. Otherwise it is set to 1KHz. This is set in the Rowberg MPU libraries. Not sure of what is achievable. DMP values are at fixed rate of 200 Hz.. Depending on what processor you are using, there is code for DMP on Github. D.K.

Jero Posted December 29, 2015 Author Report Share Posted December 29, 2015 I'm back at the project and a little lost. How do I change DLPF? Quote Link to comment Share on other sites More sharing options...
