USB I2C Spy                                                      

USB I2C Spy

Der USB-I2C-Spy combines a I2C-Bus Tracer (100+ kHz) and a USB-I2C-Adapter (400+ kHz) on one single board. When it is connected to a I2C-Bus, then any I2C-Bus activities like Start, Stop, Slave address, READ/WRITE, Data, ACK- NACK- Bits  will be non-invasively and without Clock stetching captured and immediately transfered via USB to the Host PC. The I2CSpy Software gives the possibility to see the captured data in a well arranged table.

 

It is possible to save the captured data to different formats (CSV, ASCII, HTML, or just as RAW data) for later use. Any time later you were able to load data and analyse them. If the I2C bus is heavy loaded, then using the filter is usefull to show only messages of interest. A I2C message will be only displayed if a messages matchs the filter settings.

 

The Tool can be used also as USB-I2C-Converter with a SCL- frequency up 400 kHz. The SCL-frequency is adjustable via software. Just add, edit or delete I2C messages in a table and send one or all onto the I2C bus. I2C messages (Tables) may be laso stored to the hard disk for later use. Numerous bus participants can be purposefully adressed.

Software and Driver for Win2000, XP and Vista are inculded on delivery.

 

This USB-I2C-Spy is USB Bus-powered, therefore no separate power packs for voltage supply are needed.

 

The Tool is ideally for the embedded developers, who would like to develop own I2C-circuits. Therewith it is possible to adress/debug I2C devices or to monitor data communication between I2C devices.
