Description

The Aardvark I2C/SPI Host Adapter connects via USB and is a powerful and fast I2C and SPI host adapter. Developers can connect a Mac, Linux computer or Windows PC to the embedded system environment and transmit the serial data streams using the I2C and SPI protocols.

I2C Features

Performance of up to 800 kbps over USB with higher bandwidth compared to slower RS-232.
Supports standard mode (100 kbps) and fast mode (400 kbps) and varying speeds from 1 kHz to 800 kHz.
Supports inter-bit and inter-byte clock stretching, multi-master configurations, master send and receive, and asynchronous slave send and receive.
Software configurable I2C pull-up resistors.
Software-configurable target power pins to power downstream devices.
Repeated start, 10-bit slave addressing, and combined format transactions.

The Aardvark I2C/SPI host adapter is compatible with:

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)

† Actual system bus speed may vary based on capacity.

SPI Features

Works in master or slave mode.
Master signaling rate of up to 8 Mbit/s.
Slave signaling rate of up to 4 Mbit/s.
Send/receive full-duplex master.
Asynchronous slave send / 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 leveraged for more general use, allowing them to be used for custom signals on target systems. The 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 operating modes.

Cost-efficient and time-saving

The Aardvark adapter comes with a license-free API. The low cost of the Aardvark allows companies to provide each developer with their own I2C/SPI interface. This allows developers to fix simple problems directly and quickly instead of requesting approval for additional tools and having to solve problems in the lab. Less time means more productivity as developers can quickly and easily identify and fix problems with less downtime. Higher productivity means shorter development cycles. Projects are completed on time and on budget. The Aardvark adapter has paid for itself by saving just a few hours of engineering time.

Future-proof

The Aardvark adapter is fully field upgradeable via USB. The Aardvark adapter is constantly being improved and updates are provided free of charge. You never have to worry about not keeping up with the latest software features. Eligible software and firmware upgrades are always freely available in the downloads section of this or Total Phase's website.

Available software

Control Center Software

The Control Center allows users to fully utilize the functions of I2C, SPI and GPIO immediately. Multiple devices can be used simultaneously and a virtually unlimited number of configurations can be selected, allowing engineers to develop and test their embedded systems.

Flash Center Software

Total Phase Flash Center Software is a software package that allows engineers to quickly erase, program and verify I2C and SPI-based EEPROM and Flash memory chips. In addition, non-listed building blocks can be added within minutes via the XML-based library.

Labview Driver

The Aardvark LabVIEW Driver is a free, open-source LabVIEW instrument driver for accessing the Aardvark I2C/SPI host adapter within the LabVIEW development environment. The driver package is Windows oriented and based on the Aardvark software library.

API's

The Aardvark I2C/SPI Host Adapter has a comprehensive API for Rosetta language bindings - 32-bit and 64-bit software API C, C#, Python 2/3, .NET, VB.NET and VB6. The Labview drivers provide all of the functionality normally available to a C language developer. Windows 10, 11, Max OS X 10 - 11, Ubunto, Fedora, SuSE and Red Hat are supported.

Supported ICs

With the help of the Flash Center, I2C EEPROMSs, SPI EEPROMs and SPI Flashes can be easily flashed. Unsupported ICs can be added within minutes thanks to the self-extensible database. Our selection assistant gives you an insight into which ICs are already supported.
