VO already supports the G-series keyboards from Logitech, but in a somewhat limited fashion. At the moment the screen just shows the Vendetta logo when logged out, and bar graphs for license levels.

I know developing more features for it would take a lot of time and effort that you guys over at Guild Software probably don't have, so... Can we get an improved interface to this via Lua so that our awesome plugin community can fill in the gaps? :)

I've personally got a G13 and love it. It works great for VO's control scheme and has been rock solid since i bought it. I know there's other players who have them too.

Since the game already has support for these devices, how possible is this to add in a future release?

This would be awesome. The LCD would be the perfect place to put FPS, ping, and a guild voice chat list, among other things.

The support you speak of is that the g13 acts as a second keyboard. The LCD display is a different matter.

The basic access method for the LCD is to shove a bit mapped image to the buffer. I suspect a plug in would be able to accomplish everything you are asking for but It may have to be OS specific...

You would currently have to run a rather convoluted and hack-ish external script in order to show VO-specific information on the G13/G15/G19 LCD.

The LUA wiki indicates there is an lcd table with "functions for the Logitech G-series keyboard screens", but documentation on how to use it is lacking. Maybe what you are asking is already possible?

[EDIT] Hmm, it seems that the lcd table is actually a boolean with value false. Maybe it is a placeholder for intended future features?

The LCD table is only a table when you have a compatible device connected. It only has functions for changing what's already there (your current levels).
