LEGO Device Design Guidelines

---

Device Type and Mode statements:

---

• A device can be an input (sensor) or an output (motor) device.
• A devices caracteristics are defined by one or more entries in the "TypeData" table.
• Each entry contains a device "Type", a device "Mode" and various data representing this device Type/Mode.
• Known device Type/Mode's are read from files at startup time.
• The "sys/settings" folder is scanned for "typedataXX.rcf" files at startup and the found Type/Mode data is stored (XX = 50 -> XX = 98)
• New UART sensors applies the Type/Mode data when plugged in.

• Unknown device Type/Mode's can be inserted by byte codes at runtime (only V1.05 and newer).
