Abstract
Systems and techniques for single-wire communications are described. A described technique includes detecting transitions on a single-wire bus that are produced by a host device, determining an estimated baud rate of the host device based on the transition, and communicating with the host device based on the estimated baud rate. Determining the estimated baud rate can include charging a capacitor based on a charging rate in response to a detection of a first transition of the transitions, sampling a capacitor voltage associated with the capacitor in response to a detection of a second transition of the transitions, and adjusting the charging rate based on a comparison between the capacitor voltage and a reference voltage.
