USB-I2CTM
Driver-free USB to synchronous serial I2C slave interface
Summary
USB-I2C is a single chip USB to synchronous serial I2C
slave interface. It greatly simplifies the connection of
personal computer to a microcontroller capable of
communicating in I2C master mode. In addition to the
standard 2 I2C control lines, 11 additional Virtual I/O
lines have custom-defined functionality.
USB-I2C uses the Human Interface Device (HID) USB
profile. It does not require USB driver installation, and
so is compatible with present and future Windows, Linux
and Mac operating systems.
USB-I2C is firmware for the PIC18LF2455 and
PIC18F14K50 microcontrollers. It requires only a few
discrete components and is available 28-pin DIL and 20-
pin SSOP packages.
For I2C master applications (to control I2C slave
devices), our expandIO-USB product is more suitable.
