I understand that LINDA does not support keyboard commands.  The user manual indicates that this isn't necessary since FSUIPC supports keyboard commands. I've used these keyboard facilities in FSUIPC with great success.

The thing I'm missing, and where I'd like help if possible, is how to identify the control codes needed for the keyboard in FSUIPC.  Can this information be obtained from the actions.lua file? Or by some other means using LINDA?

The reason I ask is that i'm using a gaming keyboard (Razer Black Widow Chroma) for many of the common push button and rotary knobs in aircraft.  For each aircraft I assign various control actions to different keys, and use the keyboard backlighting to highlight them (sort of a poor mans cockpit).  In some cases the control codes are published by the aircraft developer, or others (e.g., FSUIPC comes with a complete set of PMDG control codes).  For others, the control codes aren't available, though there are LINDA modules available (QW 787). 

Any help would be appreciated.  I'm using LINDA for my HOTAS joystick and throttle, and it's great!  I just don't have enough switches and buttons on them.  

Hi Dave

You have hit one of the main problems for controlling simulated aircraft in FSX/P3D. Many aircraft do not follow the default FSX controls and FSUIPC offsets. Each developer uses its own bespoke method with different offsets. Some developers do provide a SDK (like PMDG) but others for some reason wish to keep this information to themselves. This is why LINDA was developed to get around these issues in a standardised method.

We carry out a lot of detective work trying to work out how to operate the various buttons and switches in each new cockpit. There is no standard method and not all functions can be discovered (ie. FSLabs A320X). The best advice I can give is to first try the standard FSUIPC offsets and FSX controls (see /modules/fsuipc documents) using the LINDA Tracer and see whether they have the desired effect. Otherwise, it is a case of monitoring the Lvars are see which change when a cockpit button/switch is operated in the virtual cockpit. There is no quick or easy option.

You can write short LUA functions and call them using the 'lua xxxx' functions listed in the FSUIPC keypress page; these .lua files must be placed in the /modules folder. I would recommend debugging and testing these first inside LINDA.  

Remember that LINDA offers 2 shifted modes that can be used to assign up to 3 functions to each button on your joystick/throttles. This can be easy to use than using the keyboard.
