Update on input events to Scenic: I just submitted a PR to the input_event library to support generically identifying keyboards, mice, joysticks, touchscreens, and the other random things that show up as input devices like audio input jack detectors and power buttons. Hopefully once it gets merged (it is a big change, so might take a bit), someone can help add the Scenic driver pieces to make it work.

Hi! I have the officialRaspberry PI touch display (from the ElixirConf nerves training) and it’s working great with Scenic (I even have touch working!). I didn’t have to do any special setup except for configuring scenic_driver_nerves_touch.

If you want to look at my code it’s available here: GitHub - axelson/scenic_asteroids: A toy Asteroids clone written in Elixir with the Scenic UI library · GitHub

Although it won’t work without a little tweaking because I have a few external path dependencies in there.

Edit: Now there aren’t any path dependencies, so everything should work fine.

Sadly, I don’t think anyone has written a non-touch input driver for Scenic on Nerves yet. The input driver at scenic_driver_nerves_touch only looks for a touchscreen sensor and processes events from it.

It seems like there could be a driver receives input from all input devices and sends them through Scenic. The input_event library looks like some code could enumerate the input sources and then start a listener on all of them. I haven’t studied the glue code to scenic, but I’d hope that the touch driver could serve as a good guide.
