WebSPI is a full-duplex interface; both main and subnode can send data at the same time via the MOSI and MISO lines respectively. During SPI communication, the data is simultaneously transmitted (shifted out serially onto the MOSI/SDO bus) and received (the data on the bus (MISO/SDI) is sampled or read in). Web• Serial Communication through SPI operation. Read from, write to, and simultaneous read/write (full duplex) a SPI device — by calling the read, write, and writeRead APIs. The driver also provides support for callbacks. The callback functions are called with the following events: • Transfer aborted • Transfer complete
