Interface: FastSPI

An SPI byte-level interface. Every bit/byte transmitted produces a result bit/byte. Every call to the txByte() command returns the result byte. Note: ByteSPI is a split-phase version of this interface. FastSPI should be used when a single byte transaction on the SPI is sufficiently fast.
