Looking at the i2c stuff in the schematics I see that the dallas ID device
is attached to GPIO 13. 

GPIO 20 and GPIO 11 are described as I2C clock and data respectively, and
all 3 GPIOs are avilable on the samtec.

But I thought the Dallas ID device was an I2C bus thing? So why is it on a
different GP. Am I wrong and we have i2C but it's not actually used apart
from going to the external connector, and the ID chip uses something
different? Has the i2C bus been tested yet?

Can someone explain what the i2c status is please?

Wookey
