The Devantech USB-I2C interface module makes it absurdly easy to access an I2C device through your USB interface
You hear lots about I2C, but without a microcontroller, it's a bit hard to talk to.... unless if you have a Devantech USB-I2C module that lets you interface with any I2C device via your USB port!
Devantech has even released an executable with source-code for talking to your I2C device via the USB-I2C module!
