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.

Can I Program I2C/SPI Memory Devices?

Yes, the Aardvark can program a wide range of EEPROM and Flash memory using the Flash Centre™ software.

How Long is the Aardvark Warranty

The manufacturer's standard warranty is twelve months.  However, The Debug Store offers a full two-year warranty.  We can do this because the Aardvark is so reliable.

How is the Aardvark Powered?

The Aardvark is powered from the host PC via the USB cable.  The power consumption of the Aardvark is typically just 25mA.

This avoids having to use a separate power supply.

Yes, The Aardvark Host Adapters will also support:

    Display Data Channel (DDC)
    System Management Bus (SMBus)
    Power Management Bus (PMBus)
    Smart Battery Bus (SBBus)
    Intelligent Platform Management Interface (IPMI)
    Two-Wire Interface (TWI)

Can the Aardvark Support Multiple Slave Addresses?

Yes and no.  The Aardvark can only behave as one I2C address node at any one time.  However, the slave address can be changed by using the Aardvark API Software as required.

Does The Aardvark Support I2C Clock Stretching?

Yes, clock stretching is supported by the Aardvark as a Master or a Slave.

Clock stretching can only be initiated by the slave device.  It does this to extend an I2C bus cycle.  Note that not all I2C Master or slave devices may support clock stretching so this needs to be considered when clock stretching is relied upon.

Can the Aardvark adapter be used for programming EEPROMs and Flash memory?

Yes, the Aardvark is excellently suited for programming I2C and SPI-based EEPROMs and Flash memory devices. The included Flash Centre Software supports over 500 memory chips from major manufacturers including Atmel, Microchip, Intel, STMicroelectronics, Cypress, and many others.

For production environments, multiple Aardvark adapters can be used simultaneously for parallel programming operations.

What GPIO capabilities does the Aardvark provide?

The Aardvark adapter provides up to 6 GPIO pins that can be configured for general-purpose input/output operations. When operating in I2C-only mode, the four SPI pins (MISO, SCLK, MOSI, SS) become available as GPIO pins numbered 02, 03, 04, and 05. Similarly, in SPI-only mode, the two I2C pins (SCL, SDA) can function as GPIO pins 00 and 01. Each GPIO pin can be individually configured as input or output, with internal pull-up resistors available for input pins. The GPIO functionality supports interrupt-like operations through the aa_gpio_change function, which can detect pin state changes within a specified timeout period. All GPIO pins operate at 3.3V logic levels with a maximum drive current of 10 mA per pin.

What is the maximum cable length and distance limitations for the Aardvark?

The standard Aardvark ribbon cable is 130.175 mm (5.125 inches) long with a 1.27 mm (0.050 inch) pitch. For extended distances, the cable limitations depend on the communication protocol and signal integrity requirements. High-speed SPI communications up to 8 MHz should use shorter cables to maintain signal integrity, whilst lower-speed I2C communications at 100-400 kHz can tolerate longer cable runs. The device can work with custom cables, but users must ensure proper impedance matching and signal integrity. For applications requiring longer distances, level shifter boards can be used to improve signal quality, and multiple Aardvark adapters can be daisy-chained for extended reach applications. The USB connection between the Aardvark and host computer follows standard USB cable length limitations of up to 5 metres for USB 1.1/2.0 connections.

What protocols and communication standards does the Aardvark support beyond basic I2C and SPI?

Beyond standard I2C and SPI protocols, the Aardvark adapter supports several related communication standards and variants. For I2C communications, it supports Display Data Channel (DDC), System Management Bus (SMBus), Power Management Bus (PMBus), Smart Battery Bus (SBBus), Intelligent Platform Management Interface (IPMI), and Two-Wire Interface (TWI). The adapter handles advanced I2C features including repeated start conditions, 10-bit addressing, combined format transactions, clock stretching, and multi-master configurations. For SPI communications, it supports configurable clock polarity and phase settings, adjustable slave select polarity, and both MSB-first and LSB-first bit ordering. The adapter can operate with various SPI variants and custom protocols through its flexible GPIO capabilities. Additional protocols can be implemented through custom software applications using the comprehensive API, enabling support for proprietary or specialised communication standards. The device's GPIO functionality allows implementation of bit-banged protocols or custom signalling schemes as required by specific applications.

Can multiple Aardvark adapters be used simultaneously on one system?

Yes, multiple Aardvark adapters can be connected and operated simultaneously on a single host computer. Each Aardvark device receives a unique port number that can be identified using the aadetect utility or aa_find_devices API function. This capability enables parallel programming of multiple memory devices, simultaneous monitoring of different bus segments, or independent control of separate embedded systems. The USB bus provides sufficient bandwidth and power for multiple Aardvark adapters, with each device consuming less than 100 mA. Software applications can open handles to multiple adapters concurrently and control them independently through separate API calls. This multi-adapter capability is particularly valuable in production environments where gang programming or parallel testing operations are required. The Control Centre Software can manage multiple connected Aardvark adapters through its device selection interface.
