Possible to set up I2C interface using the Phidgets IO Boards?

I'm using phidgets to log data from multiple loadcells. The load cells have an EEPROM chip that stores calibration info which can be accessed via I2C.

Is it possible to implement I2C read&write streams using any of the Phidgets I/O boards?

If not I'll use an alternate microcontroller, but it would be nice if this was all possible within the Phidgets ecosystem.

There are no Phidget devices that are designed to communicate via I2C. Even if you wrote a custom procedure to encode and decode I2C communication in your program, the digital inputs on Phidgets are not fast enough to read the incoming signals.

You'll either have to use a microcontroller, or use the program running your Phidgets to calculate and store the calibration data instead of the EEPROM.
