The Aardvark I2C/SPI Host Adapter<ref>[https://www.totalphase.com/products/aardvark-i2cspi/ Aardvark I2C/SPI Host Adapter]</ref> is part of the [[Total Phase I2C Development Kit|I2C Development Kit]] from Total Phase<ref>[https://www.totalphase.com/ Total Phase]</ref>.

The Aardvark I2C/SPI Host Adapter is a fast and powerful I2C bus and SPI bus host adapter through USB. 
It allows a developer to interface a Windows, Linux, or Mac OS X PC via USB to a downstream embedded system environment 
and transfer serial messages using the I2C and SPI protocols.

== Overview ==
* I2C master and slave up to 800 kHz<ref>Actual system bus speed may vary as a function of capacitance</ref>
* I2C multi-master support
* SPI master up to 8 MHz
* SPI slave up to 4 MHz
* GPIO with selectable pins

== Aardvark adapter specifications ==
* Hardware version: 3.00
* Firmware version: 3.50
* Functions: I2C, SPI, GPIO

== Software ==
Software is freely available (download from Total Phase), but you need to register before you can download it. Linux, Windows and Mac OS X is supported.

=== Control Center ===
The Control Center<ref>[https://www.totalphase.com/products/control-center-serial/ Control Center]</ref> Serial Software provides easy access to all the features of the Promira™ Serial Platform 
(with I2C or SPI applications installed), the Aardvark I2C/SPI Host Adapter, and the Cheetah SPI Host Adapter. 
Within minutes, developers can make full use of I2C, SPI, and GPIO functionality.

=== Flash Center ===
Flash Center<ref>[https://www.totalphase.com/products/flash-center/ Flash Center]</ref> is a software package that allows engineers to quickly erase, program, and verify I2C- and SPI-based EEPROM and Flash 
memory chips that are interfaced through Total Phase's Promira™ Serial Platform, Aardvark™ I2C/SPI Host Adapter, 
and Cheetah™ SPI Host Adapter.

=== Aardvark Software API ===
Aardvark Software API<ref>[https://www.totalphase.com/products/aardvark-software-api Aardvark Software API]</ref>
Rosetta Language Bindings - 32-bit and 64-bit Software API and Shared Library for C, C#, Python 2/3, .NET, VB.NET, and VB6. 
Note that this software requires an update of the firmware to version 3.50. Please read the UPGRADE.txt in the package 
because some API calls have been changed.

=== Other software ===

The Aardvark LabVIEW Driver<ref>[https://www.totalphase.com/products/aardvark-labview/ Aardvark LabVIEW Driver]</ref> is a free and open-source LabVIEW Instrument Driver for the Aardvark I2C/SPI Host Adapter. This version supports LabVIEW 2017 and above.

Linux - USB drivers<ref>[https://www.totalphase.com/products/usb-drivers-linux/ USB Drivers - Linux]</ref> - the Linux driver is based on libusb and there is no need to install any other drivers on the operating system. This package contains configuration files to enable device access (permissions) for all users.

Aardvark Firmware Update Utility

Firmware update utility<ref>[https://www.totalphase.com/products/aardvark-update-utility/ Aardvark Firmware Update Utility]</ref>. Note that this firmware requires an update of the software to version 3.00 
Unzip into a temporary folder and run aaflash-win32.exe (Windows), aaflash-linux (Linux), or aaflash-darwin (Mac OS X) from the command line.

The executable is fro 32-bits linux, perhaps that is why it fails:

: Installed Control Center on my machine (Debian 10.5), installed the permissions file (copied <code>99-totalphase.rules</code> to <code>/etc/udev/rules.d/</code>) and plugged in the  Aardvark adapter. Started Control Center, Connect (ctrl-O), selected the Aardvark adapter and mode (I2C - SPI, I2C - GPIO, SPI - GPIO, GPIO only, SPI Master, Batch Mode). The program works, and the adapter is connected. Connected the Aardvark to the I2C / SPI Activity Board, selecte Btach Mode, and loaded scripts (examples) to control lights, read eeprom and so on. It works. [[Bruker:Tingo|Tingo]] ([[Brukerdiskusjon:Tingo|diskusjon]]) 11. sep. 2020 kl. 15:10 (CEST)
