osvr / osvr-cpi Goto Github PK

Looks like a nice GUI that's "almost" cross platform already.

I started doing some changes here: https://github.com/ChristophHaag/OSVR-CPI/commits/master

Some random things:

1. Most of the GUI and serial stuff should work on linux (I haven't really tested much besides the Check FW Version button) but I haven't done the firmware update button yet.
2. thePort->waitForReadyRead(5000) doesn't work on linux, it always returns false. Should only matter for the firmware update though.
3. Serial port is hardcoded to /dev/ttyACM0, with a couple of minutes on google I didn't figure out how to get a serial port by USB ID.
4. A hand rolled file watcher using windows APIs in the usersettingsplugin... I've removed that part of the code so far but I haven't found a good cross platform alternative. Candidates are
5. QFileSystemWatcher. I just can't get it to work. Someone with better Qt knowledge may.
6. fswatcher looks like it has a broken CMake setup. May be worth looking further into.
7. efsw is simple and works easily, but it looks like it only notifies on directory changes, not file changes. You could just listen to all changes in the directory where the config file is but on linux I want to put it into ~/.config/osvr_user_settings.json and so you'd get notified about any and all changes in ~/.config. Alternatively the config file could go into ~/.config/osvr/osvr_user_settings.json.

If anyone has some tips how to proceed I'd be happy to try them.
