GPIO-TO-GPIO COMMUNICATION ON MULTI-NODE DAISY-CHAIN NETWORK

摘要

Disclosed by the present invention are a system and a technology for general purpose input/output (GPIO) to GPIO communication on multi-node daisy-chain network. In some embodiments, a transceiver can support GPIO among a plurality of nodes without host intervention after an initial programming. In the embodiments, a host can be required only for the initial setup of a virtual port. In some embodiments, a GPIO pin can be an input (capable of changing a virtual port) or an output (capable of reflecting a virtual port). In some embodiments, a plurality of virtual ports can be mapped on one GPIO output pin (for example, with values of OR operation). In some embodiments, a plurality of GPIO input pins can be mapped on one virtual port. For example, values of the plurality of GPIO input pins can be OR operated together even if the values come from a plurality of nodes.;COPYRIGHT KIPO 2017
