Abstract
Calibrating devices communicating on the shared bus can assist in reducing conflicts on the bus and the resulting loss of data. For example, the timing of transmission of data from one device to another device on the shared bus may be adjusted to compensate for delays on the shared bus. For example, the transmitting device may adjust transmission to an earlier time than the programmed time by an amount proportional to a known delay, such that the signal arrives at a receiving device at the programmed time. When the adjustment is not able to obtain a desired alignment or would cause conflicts on the shared data bus, the timing may be adjusted to delay the transmission, rather than advance the transmission, such that the adjusted transmission time results in the receipt of the signal at the receiving device in an unused time window after the programmed time.
