Hi,
I am new with the arduino board and I2C, and I am having problems using it. I went through a couple of tutorials, but they are about eeprom.

I wanted to know if anyone has code to use with the AD7746 capacitive sensor.

Thanks...

Google search got me here: http://www.sparkfun.com/commerce/product_info.php?products_id=7918

There is example C code on that page.  Maybe that could be a start?
I yield() for co-routines.

Hi, thanks for the reply.
I checked out that code, but i am having trouble converting it to the arduinos usage of the two-wire librarie.

Thanks,

Hmmm.  Looks like you are going to have to figure this out on your own.  There is also this Russian page that has a lot of details on the engineering: http://blog.makezine.com/archive/2009/03/diy_capacitive_touchpad.html
Actual grungy details and device specific code you might have to just figure out on your own.
