Abstract
A method for determining a type of a device connected to an inter-integrated circuit (I2C) includes steps of: a) transmitting requests to bus addresses of the I2C, respectively; b) upon receipt of a response message transmitted by a device in response to receipt of one of the requests from one of the bus addresses, determining that the device is connected to said one of the bus addresses; and c) according to a lookup table that includes plural of entries, each of which has a corresponding device type and respective address set consisting of at least one reference address conforming with one of the bus addresses, determining a type of the device as one of the device types in the lookup table with reference to said one of the bus addresses.
