How to send vibration to xbox 360 controller using python on linux?

Question

linux

Actually the question is asked, I do not have enough qualifications and knowledge to understand and solve.
There are the following inputs:

1. Documentation for the module for sending vibrations to the gamepad.
   
2. Source code for the test program for checking vibrations written in C.
   
3. I'm using the built-in driver for the Xbox 360 controller Xpad - source , documentation .
   

Can anyone suggest a direction or give an example of the implementation of an analogue of fftest in python?

Answer 1

The necessary code was found , which, with the help of a slight modification, allows you to do the necessary actions, in the example, launching 4 vibrations lasting 2 seconds each with a 2-second interval (the first vibration does not work for some reason).
