About

An instrumentation panel for displaying NMEA and SignalK telemetry data, specifically on electronic ink displays.

NMEA-0183 telemetry data is received on UDP port 10110.

Note

Please note this is ALPHA quality software.

• Essentially, the program currently only demonstrates two features separately: Telemetry receiver vs. Rendering and display.
• Many details will still need to be implemented.
• There might be dragons.

Features

• Receive and parse NMEA sentences
• Render user interface as PIL image
• Display user interface on different backends: PNG, pyglet, PySDL2, eips

Device support

• Desktop: Linux, macOS, Windows
• E-book devices using electronic ink displays: Amazon Kindle, Kobo eReader, Tolino eReader

Setup

pip install --upgrade boatface[ui]

To install the latest development version from the repository, invoke:

pip install --upgrade git+https://github.com/maritime-labs/boatface#egg=boatface[ui]

Usage

Terminal:

# Submit telemetry messages in NMEA-0183 format to UDP broadcast.
pip install calypso-anemometer
calypso-anemometer fake --subscribe --rate=hz_8 --target=udp+broadcast+nmea0183://255.255.255.255:10110

# Listen on the network for NMEA-0183 messages and display them on the terminal.
boatface log --source=udp+broadcast+nmea0183://0.0.0.0:10110

GUI:

# Display demo data in preview application, single-shot.
boatface ui --source=demo:// --display=viewer

# Display demo data on the screen, using the `eips` program, in landscape orientation.
boatface ui --source=demo:// --display=eips --landscape

# Display demo data on the user interface, using Pyglet.
boatface ui --source=demo:// --display=pyglet

# Display demo data on the user interface, using SDL.
boatface ui --source=demo:// --display=sdl

An example NMEA-0183 sentence emitted by calypso-anemometer is:

$IIVWR,154.0,L,11.06,N,5.69,M,20.48,K*65

More options:

# Enable verbose output.
boatface --verbose ui --source=demo:// --display=pyglet
