COMMUNICATION APPARATUS WITH FEEDBACK

摘要

In accordance with one or more example aspects of the disclosure, communications are effected on a bus using bit time and slew rate feedback. As consistent with one or more embodiments, communications are effected in a network including a master circuit and a plurality of slave circuits, on bus that is controlled by the master circuit corresponding to master and slave data communication. A feedback signal is provided, which is indicative of a slew rate and bit time of signals communicated between the master and slave circuits on the bus. Data is transmitted on the bus by generating output signals via a waveform corresponding to an input signal, and controlling the waveform based upon the slew rate and bit time indicated via the feedback signal.

1. An apparatus for communicating in a network including a master circuit and a plurality of slave circuits on bus that is controlled by the master circuit corresponding to master and slave data communication, the apparatus comprising:
a feedback circuit configured and arranged to provide a feedback signal indicative of a slew rate and bit time of signals communicated in the network between the master and slave circuits on the bus; and a data-transmission circuit responsive to an input signal and a feedback signal received from the feedback circuit, the data-transmission circuit configured and arranged to
communicate data over the bus using control provided by the master circuit, andtransmit data on the bus by generating output signals via a waveform corresponding to the input signal, and controlling the waveform based upon the slew rate and bit time on the bus and indicated via the feedback signal.
