Introduction

This EVM serves as an interface adapter or a bridge between a host PC (IBM™

compatible) and one or multiple slave devices via a standard type-A to mini-B USB

cable. The communication between the USB interface adapter and the host PC is via

USB, while the communication between the USB interface adapter and the slave

device(s) is via an inter-integrated circuit (I2C) and/or general-purpose inputs/outputs

GPIOs. The bridge converts communication transactions between the USB and

I2C/GPIO.

Note:

For the USB interface adapter to communicate with multiple I2C

slaves, build a special 10-pin ribbon cable with multiple connector(s),

so that all the I2C slave devices can be daisy-chained together on

the same ribbon cable.

In order to operate this USB interface adapter, the following items are required (see Figure 1-1):

• USB interface adapter in an enclosure

• Standard type-A to type-mini-B (5-pin) USB cable

• 10-pin ribbon cable with connectors on both ends
