I don't know of any existing code for this, but it will be fairly simple to do your own.
The G145 uses two analog gyros interfaced over using an I2C analog to digital converter. The schematic, datasheets and example code for the Roboard are on Roboard site. Their example code show the simple sequence of I2C commands used to talk to the AD7998 A2D.
There are lots of I2C master implementations for the Atmega16, so just use the one of these most convenient to your development environment and then perform the same I2C commands

I have tried, but address 0x21h is not used. In datasheet, the address is 0x40h, It also can not be used. So, what i2c address for A2D?

Hi,

the gm-145 address is 0x21h (7-bit).

Therefor, if want to write data to gm-145, you will set 8-bit address (0x21)<<1.

If want to rea data from gm-145, you will set 8-bit address (0x21)<<1 + 1.

you can refer the roboard web http://www.roboard.com/G145.html.
