The Aardvark™ I2C/SPI Host Adapter is a fast and powerful I2C bus and SPI bus host adapter which connects to a host PC by USB. It lets you interface a Windows, Linux, or Mac OS X PC to the I2C or SPI bus of your target hardware so you can test devices connected to the bus and program Flash memory devices.

The Aardvark™ includes the well-known Total Phase Control Center software which makes it easy to control devices connected to an I2C or SPI bus. Automatic testing of your devices can be done by the use of custom-written scripts, making the Aardvark™ ideal for use in the production environment for board testing. Free programming software is also included so Flash devices can also be programmed. 

The Aardvark™ is often used by third-party device manufacturers to ship with evaluation kits and for use in their production processes.

What is an SPI Interface?

The SPI or Serial Peripheral Interface can operate at much faster data rates than the I2C Bus. The Aardvark™ will operate up to 8MHz as a Bus Master.

Each device on the Bus has its own Chip Select Line, activated by the Bus Master. The interface consists of four lines:

  • MOSI, or Master Data Output
  • MISO, or Master Data Input
  • SCLK, or Serial Clock
  • NSS, a Slave enabled signal, controlled by the Bus Master, often referred to as Chip Select.

Is there any Software Support?

Of course. The Total Phase Aardvark™ connects to a host PC via a Full-speed (USB 1.1 compliant) USB interface. Software Drivers are supplied for Windows. Linux and Mac OS X operating systems. The drivers provide low-level interfaces to control the Aardvark™.

Application Software

The Aardvark™ is a very versatile interface, capable of being controlled by a range of application software. Total Phase provides ready-to-run applications for device control and memory programming and ready-build interfaces to third-party software such as LabVIEW and your own applications written in C/C++, C#, .NET, Python and Visual Basic.

Control Center Serial Software

The Control Center Serial Software has been developed by Total Phase to support the Aardvark™ I2C/SPI, Cheetah™ SPI Interface, and PROMIRA™ Serial Platform.

The software allows you to create high-level scripts for reading and writing to devices via the Aardvark™. I2C and SPI messages can also be downloaded for subsequent analysis and data patterns loaded for transmission over the interface under script-control.

The software is regularly updated and supplied free of charge by Total Phase for download.

Flash Center Software

The Total Phase Flash Center software allows you to read, program, erase and erase a wide range of I2C and SPI-based EEPROMS and Flash memory devices.

The software is fully compatible with the Aardvark™ I2C/SPI Interface, Cheetah™ SPI Interface and PROMIRA™ Serial Platform.  Take a look at the Flash Center User Manual.

Fast Programming Speeds

Programming using the Aardvark™ is very cost-effective when programming smaller devices. When programming larger SPI devices, we recommend using the Cheetah™ High-speed SPI Interface.

Gang Programming Support

Multiple Aardvark™s can be connected to a single PC allowing parallel programming for larger production runs.

Are New Devices Support

Of course, Total Phase supports the most common devices out of the box. If you need support for a new or more obscure device then it is easy to import an XML-based configuration file from the device manufacturer so you can start programming without delay.

Aardvark™ LabVIEW Driver

The Aardvark™ LabVIEW Driver is a free, open-sourced LabVIEW Instrument Driver supporting LabVIEW 2017 and later. Older versions of LabVIEW are also supported by downloading a suitable driver.

Rosetta Language Bindings

The Rosetta Language Bindings support application software written in C/C++. C#, .NET, Python and Visual Basic 6.

These allow custom applications to be written by you to give full-control over your Aardvark™ I2C/SPI interface.

Can my Aardvark™ be Upgraded?

Yes, The Aardvark™firmware is stored in internal Flash Memory, which can be updated, free of charge when new firmware is released by Total Phase.

Total Phase offers this free service which secures your investment in their products.

Who else uses the Aardvark™?

The Total Phase Aardvark™ has been the number one choice of system developers worldwide since the early 2000s; used by major electronics companies worldwide as part of their in-house development and test activities and frequently shipped with development kits and evaluation platforms to worldwide semiconductor clients.

You can feel confident that by choosing the Aardvark™ I2C/SPI Host Adapter, you will have made the right choice, like many other major electronics players before you.

The Total Phase Aardvark™I2C/SPI Interface is the perfect debugging tool for every developer working with the I2C or SPI bus. This interface is a powerful and efficient tool that works on I2C and SPI bus services and allows developers to connect it with Windows, Mac OS or Linux run computer systems via a fast USB connection. This interface allows users to downstream embedded system environment and transmits serial messages to the computer using SPI or I2C protocols.

The USB interface also provides scheduled updates of this adapter and makes this tool future-proof whilst being field-installable. The Total Phase Aardvark™ I2C/SPI Interface is a cost-effective debugging tool and very efficient for companies and organisations that are planning to increase their productivity.
