Abstract:
1. A method comprising: at an electronic device comprising a first input and a second input: setting, during a startup state, the first input to set a general purpose input/output (GPIO) of a first slave device to control the first slave device to indicate an identity of the first slave device on a 1-wire bus; setting, during the startup state, the second input to set a GPIO of a second slave device to control the second slave device to indicate an identity of the second slave device on the 1-wire bus subsequent to the first slave device indicating the identity of the first device on the 1-wire bus; determining an event of a computing system that requires a function of one of the first slave device and the second slave device; and in response to determining the event, changing from the startup state to an operational state and enabling the first and second slave devices to implement operational functions, wherein the first slave device and the second slave device are each connected to the computing system comprising an input/output (I/O) interface, and wherein the method further comprises receiving, at the I/O interface of the computing system, the indications of the identities of the first and second slave devices.
