Hi Jose,
I think this is an excellent idea. I have the same focuser and would also like to be better able to control it via the joystick when I do visual observation with my scope.
I am not really familiar with coding, but my understanding is that you have to work your way through the indi structure, i.e. many functions are defined in the parent classes i.e. you have to look e.g. into the "indifocuser.h" file. I also have not yet understood, where the joystick support within the focuser driver is being defined. The general joystick functions themselves are defined in the "joystick.h" and "joystick.cpp" files, which you find under indi/drivers/auxilliary. Hope that helps a bit.
I feel it would be great, if you could use the thumbstick to adjust focus. That way you could use the analog values to make the focuser go slow or fast depending of how much you press.
Here is a link to a project to build a stand-alone controller to achieve just that:
