jsfw
Linux only utility to forward uevent devices over network through a tcp connection.
Usage
Start client:
jsfw client [server address] [server port]
Start server:
jsfw server [port]
When a device is connected to the server host, jsfw will notice it and assign it to one of the client which will in turn create a virtual device based on it.
The code can theoretically support any kind of device (mouse, keyboard, joystick...) but is artificially limited to PS4 controllers (see hid.c::filter_event), because the hidraw interface used to set additional device state (led color, flashing, rumble) only works with them. This could be easily edited tho (see hid.c::apply_controller_state, net.h::MessageControllerState, net.c::{msg_serialize, msg_deserialize} and client.c::JControllerState). To set the controller state from the client write the json state to the fifo (either /tmp/jsfw_fifo or /run/jsfw_fifo depending on if JSFW_DEV was set during compilation, see Makefile).
The format for the controller state takes this form (comments not allowed):
{
"led_color": "#ff0000", // hex color string
"flash": [0.04, 0.11], // values are 0-1, first is time on second is time off
"rumble": [0, 0], // values are 0-1
}
Any value can be ommitted, extra values will be ignored.
Building
Dependencies
None apart from libc, libmath, pthreads, and linux headers.
Compiling
Use the makefile, or open it and do things by hand, there's nothing magic in there.
make jsfw
output will be ./jsfw.
