A one-wire transmission protocol utilizes transition interval coding in which a value of a transmitted symbol is determined by comparing an interval length between the voltage transition associated with the transmitted symbol and a prior voltage transition on the communication link, to a threshold transition interval provided to the receiving device during the transmission sequence that includes the transmitted symbol. If the interval length of the symbol is below the transition interval threshold, the symbol is determined to be a first value and if the interval length of the symbol is above the transition interval threshold, the symbol is determined to be a second value. The transition interval threshold is provided in a start sequence that includes at least two transitions. The threshold transition interval width is based on one or more transition intervals determined during the start sequence. |
