- 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.
The Aardvark adapter comes complete with a royalty-free API.
The low cost makes it affordable for a company to provide every developer with their own interface. The benefits of every developer having their own interface are:
- Less time wasted because developers do not have to share tools or go to the lab to debug simple problems.
- Less wasted time means higher productivity because developers can identify and fix problems quickly and easily with less down-time.
- Higher productivity means shorter development cycles. Projects get done on time and on budget.
By saving just a few hours of engineering time, the Aardvark adapter will have paid for itself.
The Aardvark adapter is completely field-upgradable via USB. Total Phase is committed to improving the Aardvark adapter and making these improvements available to our customers.
You will never have to worry about being out of step with the latest software features. Eligible Software and firmware upgrades are always freely available in the Downloads section of this website.

Aardvark Host Adapter Review by Bryan B.
Rating Our group has been using your Beagle analyzers for a number of years as a way to streamline development. When development of new system controller of a controller/module pair got bogged down we bought an Aardvark Host Adapter to keep testing of the i2c bus messaging for the module moving forward.

Pretty good product Review by Peter T.
Rating the device is reliable and works as expected. I'd like to see a model where you have logiv level control inside the Aardvark, instead of having another level shifter board...which is larger than the Ardvark itself. I think you could sell this device at a premium, just as Labview does with NI USB-8451 vs. 8452.
Adding this functionality would give the device back it's semi portable functionality. Using a level shifter makes it completely non-portable. (Posted on 8/30/15) -
Aardvark I2C/SPI - Great Power for the Price Review by Chris j.
Rating Aardvark's capabilities for I2C/SPI make for a great all around tool for embedded systems work. The Flash Programmer SW allowed us to quickly setup a simple flash programming fixture. Also the I2C APIs are great and allowed development of custom I2C tools in Python for our application. (Posted on 6/23/15)

Great Tool Review by Al B.
Rating I have been using this device for several years, developing small financial devices. We hang 3 peripherals off of a SPI bus, and selected I2C ports. I have sent commands to watch responses, and also simply monitored streams of data. Works great for either. Reasonably clean interface, good capture response. (Posted on 3/31/15)
