树莓Pi 4的Azure IoT中央器件模板

Question

我只是在跟踪本文件，我发现没有Raspberry 4的设备模板，但是对于像MXChip这样的设备，它是有意的吗？或者有什么方法可以获得Raspberry Pi 4的设备模板？

Answer 1

这是故意的。设备模板描述设备的功能。例如，MXChip将发送温度、湿度和运动事件(以及其他事情)，这将在设备模板中描述。您在屏幕截图中发布的ReButton将具有按钮按下功能(支持单/双/三重/长点击)。

这就引出了没有Raspberry模板的原因，这个设备本身没有开箱即用的功能将它连接到IoT Central。我可能会决定给它添加一个温度传感器，所以我将构建一个模板来描述这个功能。但是您可能会决定在其中添加一个按钮和一个LED，因此您将构建一个描述这些功能的模板。

正如您在评论中指出的那样，如果您想要一个起点，您将从最基本和几乎为空的能力模型开始，但是您不能没有任何接口的能力模型，因此您可以添加微软提供的DeviceInformation接口。您将需要编写代码，您的Raspberry将运行实际填写这些字段！

我的建议是在IoT Central中创建自己的，虽然以上是一个不错的起点，但在IoT Central中创建自己的接口只需一分钟，然后您就可以添加自己的接口了。

希望这能解释一点！如果你需要澄清的话请告诉我。
