This is a fork of the open source core component of Synergy, a keyboard and mouse sharing tool. For compilation and configuration, check the main repo.
One current limitation of Synergy is the relatively powerful control it needs to control the mouse and keyboard. For this reason, operating systems like Android and Chrome OS will likely never support Synergy directly.
However, by employing the use of a programmable HID (such as a Raspberry Pi Zero W), Synergy can be used on pretty much any device that supports USB devices.
To setup the Raspberry Pi Zero W to act as a USB device, follow the guide found at https://www.aidanwoods.com/blog/building-a-wifi-enabled-usb-rubber-ducky/, with its corresponding repo. In particular, this issue contains a necessary workaround.
HID Synergy requires three USB devices, a mouse, a keyboard, and a digitzer (for absolute mouse functionality), so use [this repos hid.sh] instead of the one from the tutorial.
After compiling Synergy on the Raspberry Pi Zero W, there is a single new option for use with the client:
[--hid <mouse> <keyboard> <digitizer> <width> height>]
The mouse, keyboard and digitzer arguments correspond to the HID file
path for each. For the hid.sh above, these should be /dev/hidg0,
/dev/hidg1 and /dev/hidg2 in order.
The width and height arguments describe the width and height of the desired client screen. Modifying these values while maintaining the same aspect ratio will change how quickly the mouse will move on the client device.
