WebSPI is a synchronous serial communication protocol used to communicate between devices. SPI uses a master-slave architecture, with a single master device initiating the communication frame, and operates in full-duplex mode (data is sent and received at the same time). In digital systems, data is transferred in the form of 1’s and 0’s.
