Display Data Channel (DDC)
System Management Bus (SMBus)
Power Management Bus (PMBus)
Smart Battery Bus (SBBus)
Intelligent Platform Management Interface (IPMI)
Two-Wire Interface (TWI)
SPI

Operates in master or slave mode.
Up to 8 Mbps master signaling rate.
Up to 4 Mbps slave signaling rate.
Full duplex master transmit/receive.
Asynchronous slave transmit/receive.
Software configurable target power pins to power downstream devices.
Software configurable Slave Select (SS) polarity in master mode.
GPIO - General Purpose IO

I2C and SPI pins can be repurposed for more general use, allowing them to be used for custom signals on target systems.
GPIO functionality can also be combined with I2C or SPI to interact with your target system.
GPIO configuration is cached internally to preserve settings between operational modes.
Future-Proof

This host adapter is completely field-upgradable via USB. We are committed to improving the adapter and making these improvements available to our customers free of charge. There are no yearly support contracts and no software update fees.

Control Center Software

The Control Center™ Software is a graphical application that provides an easy way to get developers up and running quickly. The Control Center eliminates the need to write custom software to control your adapter and is FREE!

Some features include:

Full access to all I2C/SPI Host Adapter functionality.
Batch scripting capability with the XML Batch Script language.
Logging of all transactions in and out of the adapter.
Control of multiple devices simultaneously.
LabVIEW Driver

The LabVIEW Driver is a free, open source driver for use with LabVIEW. All API functions are supported. The driver comes complete with example I2C, SPI and GPIO applications.

Rosetta Language Bindings - Development API

Develop custom solutions in C/C++, C#, VB, .NET, and Python
Clean API is well-documented and easy to integrate
Fully Windows, Linux, and Mac OS X compatible
Royalty-free API can be used without licensing fees
No extra development kit to buy, you can download it before you even buy a I2C/SPI Host Adapter.
Compatibility

The I2C/SPI Host Adapter was engineered from the very beginning to be a cross-platform device. The software and utilities for the Adapter function on Windows, Linux and Mac OS X so that you can develop software for your preferred platform.

Windows

The software is officially supported on Windows XP (SP2 or later, 32-bit and 64-bit), Windows Vista (32-bit and 64-bit), and Windows 7 (32-bit and 64-bit)

Linux

The software has been designed for Red Hat Enterprise Linux 4 and 5 with kernel 2.6. Customers have reported successful operation with SuSE and Ubuntu distributions. Please be aware that there may be significant differences and idiosyncracies in the way that different distributions of Linux operate. As such, we may not be able to support your particular distribution of Linux. Support will be offered on a case-by-case basis.

Mac OS X

The software is supported on Intel versions of Mac OS X 10.4 Tiger and 10.5 Leopard.

64-bit Support

The software will run on 64-bit Windows, Linux, and Mac OS X systems as a 32-bit application.
