Brain

The Brain is the computer of a MUXEN installation. It reads the CAN bus, keeps the state of every device on board, runs the automations, serves the screens, and talks to the outside world. It is not a central point: the modules keep switching the boat with the Brain off.

What runs on it is a set of applications, each with one job and its own manual. This section collects those manuals, plus Raken, the configuration interface you use day to day.

Where to start

• Raken — the configuration interface, on port 8080 of the boat computer. Start here for tank calibration, spare outputs, adding a BLOC 8.
• Boat — the device model: what is on the bus, and the MQTT topics every device publishes.
• Sensors — turning a raw electrical reading into a named quantity: tanks, probes, shunts.
• Diagnostic tools — what to run when something on the bus is not answering.
