Set IIC Address
================

Using the ``SetOptionValue()`` function in the API, you can set various control values for the current device.

To set the IIC address, set ``Option::IIC_ADDRESS_SETTING``.


.. Attention::
  Only support S210A/2100

Reference Code:

s210a/s2100：

.. code-block:: c++

  auto &&api = API::Create(argc, argv);
  if (!api) return 1;
  bool ok;
  auto &&request = api->SelectStreamRequest(&ok);
  if (!ok) return 1;
  api->ConfigStreamRequest(request);
  Model model = api->GetModel();
  if (model == Model::STANDARD210A || model == Model::STANDARD2) {
    api->SetOptionValue(Option::IIC_ADDRESS_SETTING, 0x31);
    LOG(INFO) << "Set iic address to " << std::hex << "0x"
              << api->GetOptionValue(Option::IIC_ADDRESS_SETTING);
  }
