The controller is currently being developed for MechWarrior online, but Razer has not promised delivery as far as I know. The name Artemis for the controller comes from the original name given to the Mech controls from BattleTech I believe. It would be a lot of fun if the controller is released and Artemis SBS supports it, particularly the screen.
I'm hoping an update to Artemis will make it possible to build more feature-filled controller than what is currently possible.
I've just bought an Arduino Leonardo for prototyping a controller, because it can be used to emulate a keyboard, however getting data from the game isn't currently possible, so there are very few things that the controller could display.
Glad to see much more on the keyboard mappings! Turns out the arduino could be set up to interpret DMX output, which i could use to output shield status, docking and such, however for now i havent played with it enough to test that out.
I don't think this works with my Arduino. The software used in that article doesnt accept my Arduinos as acting through a DMX interface, which I think it due to the fact that because they are newer, they don't use the FTDI USB -> Serial chip which was common on older Arduinos.
If the game could output a DMX signal on a regular USB/Serial port, the Arduino might be able to easily recieve it. Hard to say, as I am still a beginner on the subject.
