- 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.

easy plug and chug - saved a bunch of time! Review by Victor
Rating Very easy to use once you get it up and running - was able to quickly diagnose improper protocol on my I2C bus, especially start/stop bits. Some improvements: 1) include a decal of the connector pin-out on the body of the pod. I went ahead and printed my own out, and attached it, so I don't have to always go back to the manual every time I'm making a connection. 2) make it a bit clearer which program should be downloaded from the software page.
