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
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 free of charge. There are no yearly support contracts and no software update fees.
Updates will be available for download from Total Phase's Downloads section.
Software
The Aardvark 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 Aardvark adapter and is FREE!
Some features include:
- Full access to all Aardvark I2C/SPI Host Adapter functionality.
- Batch scripting capability with the Aardvark XML Batch Script language.
- Logging of all transactions in and out of the adapter.
- Control of multiple devices simultaneously.
Aardvark LabVIEW Driver
The Aardvark LabVIEW Driver is a free, open source driver for use with LabVIEW. All Aardvark 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 Aardvark I2C/SPI Host Adapter.
