Abstract
A circuit component has an address determined from a voltage level applied to a single electrical contact of the circuit component. The circuit component is configured to be assigned one of at least three unique addresses and to select from among the at least three unique addresses based on the voltage level.
Claims20
A circuit component having an address, the address determined from a voltage level applied to a single electrical contact of the circuit component, the circuit component configured to be assigned one of at least three unique addresses and to select from among the at least three unique addresses based on the voltage level.
An electronic device comprising:
- a master circuit component;
- a plurality of secondary circuit components, each of the plurality of secondary circuit components configured to be assigned a unique address selected from among at least three unique addresses by application of a voltage to a single electrical contact of each respective one of the plurality of secondary circuit components, different levels of the voltage applied to the single electrical contact being associated with different unique addresses, the master circuit configured to define a particular one of the plurality of secondary circuit components to communicate with by transmitting one of the unique addresses over a signal line electrically coupled to a communication interface in each of the plurality of secondary circuit components.
A method of operating an electronic device, the method comprising assigning unique addresses to each respective one of a plurality of circuit components of the electronic device by applying different voltages to a single electrical contact of each respective one of the plurality of circuit components, each of the plurality of circuit components being configured to assign itself an address selected from among at least three unique addresses based upon a voltage level applied to the single electrical contact.
