Abstract
A device requiring address allocation, a device system, and an address allocation method. A control device in the device system transmits currently allocated address information and a contention start signal to each device requiring address allocation in the device system through a bus, and the devices requiring address allocation with address allocation flag information being that no address information is allocated output an address contention signal. When outputting the address contention signal, each device requiring address allocation determines whether the currently allocated address information is available according to whether the other devices requiring address allocation with address allocation flag information being that no address information is allocated already output address contention signals. When determining availability of currently allocated address information, the device requiring address allocation stores currently allocated address information, and modifies address allocation flag information to address information already allocated, thereby achieving address allocation for the devices.
