Component Abstract Bus

This card allows for interfacing with Stargate Tech 2's Abstract Bus system.

Component name: abstract_bus. Callbacks:

• getEnabled(): boolean Returns whether the local bus interface is enabled.
• setEnabled(enabled: boolean) Sets whether the local bus interface should be enabled
• getAddress(): number Returns the local interface address. number is a 16bit hexadecimal number (0xFFFF being a broadcast). Returns 0 if an address has not yet been set.
• setAddress(address: number) Sets the local interface address. number is a 16bit hexadecimal number.
• send(address: number, data: table): boolean Sends data across the abstract bus. The table data is in the form of key,value pairs, i.e lua abstract_bus.send(0xFFF, { ["action"]="dial", ["address"]="Losomdeh Salothirt Erpac" })
  • See SGTech2 documentation for more info on the Abstract Bus
• maxPacketSize(): number Returns the maximum size a packet can be sent over the bus.

The abstract bus generates a signal named bus_message if a message is received. The values are; protocol id: number, sender address: number, target address: number, data: table, metadata: table

• protocol id is the protocol version that was used.
• sender address is the address of the device sending the message
• target address is the address of the device that the messages was intended for (-1 for network broadcasts)
• data is a table of the data that was sent
• metadata is a table of data that are unique to the device that send the address
