  • Short address mode for communicating waveform
    Patent number: 10372663
    Abstract: Systems, methods, and apparatus for data communication are provided. A device operating as a bus master may be detect one or more slaves on a serial bus supporting a shortened address mode for receiving a waveform having at least one of a shortened slave address or a shortened register address. The bus master may then calculate a number of slave address bits needed to address the one or more slaves in a binary form based on a quantity of the one or more slaves and generate shortened slave addresses for the one or more slaves, respectively. A length of each shortened slave address is the number of slave address bits. The bus master may then assign a generated shortened slave address to each of the one or more slaves and send the waveform to a slave via the serial bus using an assigned shortened slave address.
