On going Issue

Asked by Suleman Mehmood

Hello Fabio,

I hope you are doing fine.
As you have answered my previous question. Thanks for the code. I want to ask you that the reading of accelerometer which i am getting, what g's are the values... 1g or 2g Can you please explain in detail please.

Also I want to ask you if you have code available to get displacement from accelerometer I believe i have to integrate accelerometer readings twice but i really do not know how to do with the coding. Can you please solve this problem i would really appreciate this.

Thanks

Suleman

Regarding accelerometer g, you already have all you need from my answers at https://answers.launchpad.net/freeimu/+question/197389 ... if you divide the raw accelerometer reading by 256 you get a value in g, meaning that an output of 1g = 9.81 m/s^2.

Unfortunately, I don't have any code for displacement to share at the moment. The idea is to gravity compensate the accelerometer readings (see http://www.varesano.net/blog/fabio/simple-gravity-compensation-9-dom-imus ), then double numerically integrate the accelerometers reading into displacements.

Can you help with this problem?
