I2C Address Conflict with OLED displays

Using Arduino Networking, Protocols, and Devices
1

Hello,

I was buying 3 of those displays: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=160874357190
There is a library here: http://www.wide.hk/download/i2c_OLED.rar

It then turned out that the devices have a hardcoded I2C address. I need to use all 3 of them, though.

Is there a way to solve this problem? Is there some kind of "I2C address changer chip" I can put between the OLED and the Arduino? Or something like a "virtual I2C library" which allows me to use 3 I2C busses on the Arduino? What would I need to change at the library?

Thank you very much!

With best regards,
Cherry

Thank you, but which one of those chips do I need and what do have to change in the library?
