Patent ID: 8324824

Claim:
A communication system, comprising: a host device comprising a first 1-wire interface controller; and a driver device coupled to the host device via a 1-wire interface, wherein the driver device comprises a second 1-wire interface controller, the second 1-wire interface controller communicating with the first 1-wire interface controller via a 1-wire communication protocol; interface commands are transmitted from the host device to the driver device via the 1-wire interface and are decoded by the second 1-wire interface controller; wherein the interface commands comprise pulse width modulation (PWM) signals and command signals for programming the driver device, the 1-wire communication protocol transmitting the PWM signals during PWM signal transmission mode and transmitting the command signals during command signal transmission mode; and wherein each interface command comprises a preamble pulse, at least one command pulse and a post-amble pulse, each interface command beginning with the preamble pulse and ending with the post-amble pulse.
