It +currently words only on Linux and have non-trivial way to set up and run. + +## Installation on Linux + +You will need a C compiler (GCC or Clang) and `make` utility. Download and +unpack zip archive of this repo or clone it with git. Then run the following +from the root of the downloaded repo directory: + +``` +make +``` + +It will produce a binary named `main`. + +## Run + +First of all you need to be able to open `/dev/uinput` as a user, unless you +decided to do everything from root. Do this for your `user` as root if you want +to be able to run the virtual keyboard as user: + +``` +chown user:user /dev/uinput +``` + +### USB + +Open up a file `/proc/bus/input/events` with some text editor or viewer. For example: + +``` +less /proc/bus/input/devices +``` + +Then find there an entry for `"Sony Interactive Entertainment Wireless Controller"`. It will look like this: + +``` +I: Bus=0003 Vendor=054c Product=09cc Version=8111 +N: Name="Sony Interactive Entertainment Wireless Controller" +P: Phys=usb-0000:02:00.0-1.4.2.4/input3 +S: Sysfs=/devices/pci0000:00/0000:00:01.2/0000:02:00.0/usb1/1-1/1-1.4/1-1.4.2/1-1.4.2.4/1-1.4.2.4:1.3/0003:054C:09CC.000B/input/input27 +U: Uniq=d0:bc:c1:a2:be:9f +H: Handlers=js0 event23 +B: PROP=0 +B: EV=1b +B: KEY=7fdb000000000000 0 0 0 0 +B: ABS=3003f +B: MSC=10 +``` + +If you don't see any entries for "Sony Interactive Entertainment something something..." and you are sure your USB cable is good, then go mess around with your kernel and find a way to enable DS4 support in the kernel. + +The line `H: Handlers=js0 event23` is what wee need. `event23` is the gamepad device.
