Convert SPI Shortcut boad to I2C shortcut

Hi All

I bought an SPI shortcut and the manual says it has a TWI breakout. I looked and sure enough the outputs are right there.

But the embedded terminal application only talks SPI

So what would be involved in creating new firmware that talks to I2C?

It has an atmega 168 on board so can I just re-program the firmware?

How?

Take a look at AVR310:
