APPARATUS AND METHOD OF POLLING ADDRESSES OF ONE OR MORE SLAVE DEVICES IN COMMUNICATION SYSTEM Russian patent published in 2015 - IPC G06F13/00 G06F13/42 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to means of communication from multiple slave devices with a master device over a shared bus for polling addresses in order to report unique address values of a slave device to the master device over the shared bus. The method comprises receiving a request signal from a master device requesting a slave device address to be sent to the master device from each salve device connected to a data line; causing the data line to be sequentially placed in logic states corresponding to bit values in a first slave device address; upon placing the data line in a logic state different from a corresponding bit value of the first slave device address, temporarily entering an idle state until another slave device has completed sending the slave device address thereof to the master device.

EFFECT: shorter time for detecting slave devices.
