SYSTEMS AND METHODS FOR MULTIBIT CODE COMMUNICATIONS

摘要

Certain implementations of the disclosed technology may include systems and methods for multibit code communications that can provide more than one bit per input port. In an example implementation, a method is provided that can include measuring an input voltage at an input port in communication with a device. The method can include comparing the measured input voltage with a plurality of predetermined reference voltage levels, and determining, based on the comparing, a device ID. The method can further include outputting the device ID. Certain implementations may further include compensating a signal associated with the device based on the identified device ID.

1. A system, comprising:
an input port having an input pin configured to couple with an identification (ID) resistor of a device; one or more comparators in communication with the input pin; a multi-tap resistive divider network comprising:
three or more resistive elements configured in series; wherein a first end of the multi-tap resistive divider network is configured to be coupled to a first voltage and a second end of the multi-tap resistive divider network is configured to be coupled to a ground;a plurality of divider taps defined by the three or more resistive elements, each divider tap of the plurality of divider taps configured to generate a corresponding voltage level for communication with the one or more comparators; and a decoder circuit in communication with the one or more comparators, the decoder circuit configured to identify the device based at least in part on a comparison of an input voltage at the input pin and the voltage levels generated by the multi-tap resistive divider network, wherein the decoder circuit outputs an identification signal representative of more than one bit per input pin.
