SERIAL PERIPHERAL INTERFACE DAISY CHAIN COMMUNICATION WITH AN IN-FRAME RESPONSE
First Claim
1. A master device connected in a serial-peripheral interface (SPI) daisy chain configuration with a plurality of servant devices, wherein the master device is configured to:
- output a master data output to a first servant device of a plurality of servant devices, wherein the plurality of servant devices are connected in a serial-peripheral interface (SPI) daisy chain configuration with the master device; and
receive a master data input from a last servant device of the plurality of servant devices, wherein the master data input comprises an in-frame response of the plurality of servant devices, and wherein the in-frame response is received by the master device in a single SPI communication frame.
