US 11,960,434 B2 · Communication device, communication system, and communication method for transmitting data blocks including signal groups conforming to a serial peripheral interface

Abstract

A communication device includes: a communication unit that adds, to a set of data blocks including a serial signal group conforming to SPI transmitted from a master in synchronization with a clock, identification information for identifying the data blocks, and transmits the data blocks to a communication partner device within one frame period of a predetermined communication protocol, or adds, to data blocks each including a part of the serial signal group, identification information for identifying each of the data blocks, and transmits the data blocks to the communication partner device in a plurality of frame periods; and a storage unit that sequentially stores a predetermined number of data blocks transmitted from the master and outputs a data block transmitted from the communication partner device in response to the predetermined number of data blocks from the master and stored, to transmit the data block to the master.

Dependent claims

A communication device comprising:

a communication unit that adds identification information to data blocks including a serial signal group conforming to a serial peripheral interface (SPI), the data blocks transmitted from a master in synchronization with a clock, the identification information identifying the data blocks, and that transmits the data blocks to a communication partner device within one frame period of a predetermined communication protocol, or that transmits the data blocks to the communication partner device in a plurality of frame periods;
and
a storage unit that sequentially stores a predetermined number oft the data blocks transmitted from the master and then outputs an other data block transmitted from a slave via the communication partner device in response to storing the predetermined number of the data blocks from the master, to transmit the other data block to the master, the predetermined number being one or more.

A communication system comprising:

a first communication device and a second communication device that transmit and receive a packet according to a predetermined communication protocol, wherein
the first communication device includes:
a first communication unit that adds identification information to data blocks including a serial signal group conforming to a serial peripheral interface (SPI) transmitted from a master in synchronization with a clock, the identification information identifying the data blocks, and that transmits the data blocks to a second communication device within one frame period of the predetermined communication protocol, or that transmits the data blocks to the second communication device in a plurality of frame periods;
and
a first storage unit that sequentially stores a predetermined number of the data blocks transmitted from the master and then stores other data blocks transmitted from a slave via the second communication device in response to the predetermined number of data blocks from the master, the predetermined number being one or more, and
the second communication device includes a second communication unit that transmits the other data blocks transmitted from the slave in response to the predetermined number of the data blocks transmitted from the first communication unit to the first communication device within at least one frame period.
