Abstract:
Systems, methods, circuits and computer-readable mediums for managing single-wire communications. In one aspect, a method includes starting a transmission cycle by transmitting a clock pulse to a single-wire bus, sampling a data bit transmitted from a single-wire device through the single-wire bus within the transmission cycle after the transmission of the clock pulse, and determining whether a sampling period of the sampling is smaller than a sampling threshold for the data bit. In response to determining that the sampling period is not smaller than the sampling threshold, the method further includes determining that the transmitted data bit is an invalid data bit, and in response: transmitting a high logic voltage level pulse to the single-wire bus for timeout and restarting the transmission cycle for retransmission of the data bit.
