I started a project where you can "log in" on a terminal (basically a Raspberry Pi with a touchscreen attached) with a wireless token (for time tracking).
What will be the best and fastest solution to display the status (basically a background picture and 2-3 texts changing depending on the status of the token) on the screen (fullscreen)? I tried it web-based with chromium, which is -very- slow...
It has to be easy to do http request and en-/decoding JSON - and please no C/C++.
Maybe python + wxwidgets?
You could use Python for this easily with just the standard library (python 2.7.3).
For the GUI you can use Tkinter or Pygame (not standard library) which both support images and text placement (and full screen). It is notable that Tkinter is not thread safe, so that may be a problem if your planning on threading this program.
For the http request you can use httplib.
For the Json related things you can use the json library.
