... Summary USB-SPI is a single chip USB to synchronous serial SPI slave interface. It greatly simplifies the connection of personal computer to a microcontroller capable of communicating in SPI master mode. In addition to the standard 4 SPI control lines, 11 additional Virtual I/O lines have custom-defined functionality. USB-SPI uses the Human Interface Device (HID) USB profile ...
