Programmed by Adrian Fiorito and Joachim Holwech (commit history does not reflect this) in Go. This project got a 23/24 score. Branch 'devel-fix' is an alternative and cleaner implementation, with the downside that the code does not work.
Slave initializes all other modules. It sets the master-module locally or joins any master-module already online on the local network.
Master is the "brain" that controls everything. Only one brain is active at any time, but every running program has a idle master that is in sync with the active master. If a computer loses connection, the idle master will become active and pick up from where on what the previous master was doing.
Works as an interface between master/slave and the communication-module. Network sorts messages between slave and master. It also does some simple message convertion.
Orders calculates orders based on a cost function. This module is used by master to decide where each elevator should go.
Driver works as an interface between hardware and software. Button clicks and other input can be accessed from the driver module.
Communication is a simple UDP-module that receives messages from any network access. All messages are sent over UDP-broadcast. Includes a simple receive-confirmation functionality that passed a error message if the message is not received.
A list of commands that slave and master use to communicate with each other.
