Even with Sandhawc the XIM would still have to know how to interpret analog values being sent to it, no? Given that the XIM is most likely looking for on or off when it comes to KB input, I would imagine this would still be a problem. Or would the KB be acting as a joystick instead?
The Xim can interpret X & Y axis input from analog sticks, it should be able to detect the same thing on an analog keyboard. WASD is essentially the left or right stick when set to Xinput mode, so it may simply detect as such. I don't know for sure, but given it's a driverless solution, it sounds possible.
Both a Nav and a kb can be plugged in at the same time, alongside the controller, and all will work concurrently. There's no reason to believe it's not possible for a kb with a mix of analog and digital inputs wouldn't work.
did you end up backing it?
No, they've already met the funding goal and I'd prefer to wait for the 2nd generation with full-range switches.
