I don't know if here is right place to ask, but I wondered how FFB joysticks calculate the force.
At least it should work like this:
[Sim] ==(Speed, angle and some external force working on your plane) ==> [Some calculator] ==(Force on control stick and rudder)==> [Some function] ==(Target torque or rot speed of motor)==> [Motor Driver]
where
[ - ] : software or program
==( - )==> : data
As for software, at least we have
- flight sim itself
- device driver of joysticks
- built-in software inside of the joysticks
And my particular questions are:
- What each of the software actually does? (For example, calculating the force can be done by flight sim, device driver and even in built-in software. I want to make clear which part does each of the software takes)
- Is there common format (protocol?) for the data? (I think there is, since we can use FFB sticks for several different sims.)
I will appreciate any information.
