I²C* Bus Interface, Monitoring and Control

AVIT Research provides a I²C and SMBus Monitoring and Control Tool.  Developed with years of experience in I²C, this tool is an embedded engineer's must.  The device is self contained (circuitry integrated into the connector) and does not require any external power source. 

The design philosophy was such that our I²C tools would not need Drivers or Installation software to use them - even our USB devices do not require an installation disk or drivers downloading from the internet - the USB carries its own drivers and initially appears an a standard Mass-Storage Device to load it's configuration file.  HyperTerminal (supplied with Windows) is used as an interface, this provides data monitoring, filtering, time-stamping, logging and even transmission (Tool and Professional version only) all without any installing of software.  There is even Help available.

Custom interfaces and functionality can easily be made using the Supplied Software Development Kit (SDK).  Full control of the I²C Bus can be achieved using the OCX interface.

  • USB Connectivity

  • Hyper-Terminal Colour Interface

  • Monitors bus data (up to 400kHz)

  • Compatible with 5v and 3.3v bus systems

  • Shows Acknowledgements (Acks/nAcks)

  • Master Transmit (Multi-Master Compliant)
    Master Request (Multi-Master Compliant)

  • Slave Receive
    Slave Transmit

  • Supports Clock Stretching

  • Master (TX/Rqt) with Bus Hold

  • Peripheral Emulation (PC interface)

  • Trigger configurable as an output
    (e.g. oscilloscope trigger or power source)

  • Trigger configurable as an input
    (event marker in data log or triggering messages)

  • Windows Software Developer Kit provides full I²C functionality of the device to VB, VBA, C or Java applications through an OCX or .NET Control.

Free Windows Software

The I²C Monitor software allows the user to harness the full power of their I²C Interface, Standard or Professional (also works with the discontinued Monitor and Tool hardware).  The application connects to the I²C device in 'binary' mode allowing 100% 400kHz busses to be monitored without any danger of loosing data.  The Graphical User Interface allows rapid and intuitive control of all I²C functionality, such as filtering and Master transmission of data (Professional/Tool only).  User 'plug-ins' can be written to interpret data into meaningful messages, or complete custom interfaces can be written to display data graphically.
