The [`Aardvark`](https://nominal-io.github.io/instro/instruments/i2c/#total-phase-aardvark) provides a driver that can be used to instantiate an [I2CInterface](/library/protocols/i2c/overview).

## Creating an [`I2CInterface`](/library/protocols/i2c/overview) with [`Aardvark`](https://nominal-io.github.io/instro/instruments/i2c/#total-phase-aardvark)

```python theme={null}
from instro.i2c.drivers.totalphase import Aardvark
from instro.i2c import I2CInterface
from instro.i2c.types import SystemDefinition

# Create system definition (see the System Definition page for details)
system = SystemDefinition()
# ... add devices to system definition ...

i2c = I2CInterface(
    name="main_i2c",
    driver=Aardvark(serial_number="123456"),
    system_definition=system,
)
```

Parameters and methods specific to [`Aardvark`](https://nominal-io.github.io/instro/instruments/i2c/#total-phase-aardvark) can be found in the [SDK](https://nominal-io.github.io/instro/).
