How does this work please?

Is this working?

I was looking to use this to figure out how the underlying visca library works.

However, from examining the code, I do not see how the controllers are hooked up to the visca code.

Is there not some mechanism like callback or update that needs to be hooked up in app to map the button presses / joystick movements to trigger visca commands?

I also do not understand how the httpHandler responds to and controls the visca ptz.

Am I missing something?
