# `ATECC508A.Transport.I2C`
[🔗](https://github.com/nerves-hub/atecc508a/blob/v1.4.0/lib/atecc508a/transport/i2c.ex#L8)

Implementation for communicating with ATECC508A parts connected over I2C

# `i2c_args`

```elixir
@type i2c_args() :: [bus_name: String.t(), address: Circuits.I2C.address()]
```

I2C transports are specified by a bus name like "i2c-1" and
an I2C address.

# `instance`

```elixir
@type instance() :: module()
```

# `init`

```elixir
@spec init(i2c_args()) :: {:ok, ATECC508A.Transport.t()} | {:error, atom()}
```

Initialize an I2C transport to an ATECC508A

Options are:

* `:bus_name` - "i2c-0", "i2c-1", etc. The default is "i2c-1" which frequently
  works on Raspberry Pis and Beaglebones
* `:address` - This is the I2C address of the ATECC508A/608A. The default
  is 0x60. It is not common to change this address in Nerves devices.

If a transport has already been created to the specified ATECC508A, that
transport will be returned. All commands to the ATECC508A are serialized
so that they don't interfere with each other.
