Temboo to Xively

Question

因此，在最近收购了Arduino Yun之后，我正在使用Temboo，但是我在通过组合Choreo获取和发布数据时遇到了问题。

我正在使用雅虎GetWeatherByAddress Choreo，并试图将我想要的个人价值张贴到Xively上。我正在使用Xively Write Choreo，并以JSON格式输入FeedData。

到目前为止，我已经成功地一次发布了两个值(湿度和压力)。不幸的是，我想使用更多，并有湿度，温度，WeatherConditions(公平，刮风等)和LDR值读数从一个面包板。所以它每10秒循环一次，读取所有这些值，然后将它们发布到Xively。即使打印到串行监视器，温度值似乎也有问题，如果我有任何比温度值更多的未注释。它也不会完成整个过程(如果成功，则返回Http 200 )，它会发布这些值，然后直接“等待”下一组要检索的值。我在哪里做错了？

我在Temboo工作。我相信我们已经通过Temboo支持解决了这个问题，所以我在这里为子孙后代回答。

通常，如果草图断断续续地工作，而您没有更改任何代码，那么很可能是RAM即将耗尽(这是资源受限设备上的常见问题)。当你的电路板RAM不足时，它会导致Choreo输入数据在你的Yün的32U4侧被覆盖和损坏。你的草图可能正好在RAM限制，这解释了为什么它有时工作，而另一些则不工作，这取决于所涉及的字符串数据量。

您可以释放一些RAM，方法是将未更改的输入(您的Temboo证书、您的Xively证书、您正在搜索的地址、任何其他静态字符串)放入存储在Linino端的设置文件中，如下链接所述：

https://temboo.com/arduino/using-settings-files

如果这还不能释放足够的内存，您可以通过删除任何不必要的串行或控制台打印语句来释放更多的内存。

希望这将有助于解决您所看到的问题。如果没有，请让我知道，我们将继续调查。

最后，这里有一些关于如何检查草图使用了多少内存的信息：
