Abstract
A one-wire protocol is described, wherein a one-wire bus has either a wired-AND configuration or a wired-OR configuration. In this protocol, data is encoded using time modulation. In one embodiment, two devices communicate with each other through the one-wire bus. One device is configured to transmit data by driving the one-wire bus high, while the other device is configured to transmit data by driving the one-wire bus low. In a preferred embodiment, transmission of data by each of the two devices is interleaved in such a fashion so that there is a bit-for-bit exchange between one device and the other device. In another embodiment, more than two devices may communicate through the one-wire bus.
