rMview: a fast live viewer for reMarkable

Instructions

To run the program you need python with pyqt5 installed. Before running the program the first time, generate the resource file with

pyrcc5 -o src/resources.py resources.qrc

Then you can invoke the program with

python src/rmview.py [config]

the optional config parameter is the filename of a json configuration file. If the parameter is not found, the program will look for a rmview.json file in the current directory, or, if not found, for the path stored in the environment variable RMVIEW_CONF. If none are found, or if the configuration is underspecified, the tool is going to prompt for address/password.

The supported configuration settings are:

{ // all settings are optional, comments not allowed
  "ssh": {
    "address": "10.11.99.1", // works over WiFi too!
    "username": "root",
    "key": "~/.ssh/id_rsa_remarkable",
    // alternatively to key, "password": "****" is supported
    "timeout": 1 // in seconds
  },
  "orientation": "portrait", // default: landscape
  "pen_size": 10, // set to 0 to disable
  "pen_color": "red",
  "fetch_frame_delay": 0.03 // sleep 0.03s on remarkable before fetching new frame (default is no delay)
}
