设定IIC 地址¶
通过 API 的 SetOptionValue() 函数，就可以设定当前打开设备的各类控制值。
设定IIC地址，就是设定 Option::IIC_ADDRESS_SETTING。
注意
仅支持S210A/S2100
参考代码片段：
s210a/s2100:
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);
}
参考运行结果，于 Linux 上：
s210a/s2100:
