Custom Controllers for Remote Tilt

I have a PintV (refloat), an ESP32 dev kit and a remote with a joystick I can connect to it (salvaged from another robotics project, not anything typical you would buy for this). I’m currently writing some code so I can use this as a method of input for remote tilt, but I’ve got a few questions from a software side.

The COMM_SET_BALANCE_INPUT_INFO (cmd 75) payload, specifically what does Refloat actually expects in those bytes, is there a standardised byte layout?

Is remote_tilt just a single float value, or do I need to ship additional fields alongside it?
Is the expected input range in degrees (eg ±10) or is it normalised from -1 to 1?

I have a white board so I don’t think an express is the way to go here, plus I don’t really want any other functionality

Appreciate any help, if I get this to work I’ll probably make a full guide on using custom controllers
