收集 Arduino Yun 的数据

为发布来自 Arduino Yun 设备的数据创建一个通道并开始侦听该通道.

In[1]:=

channel = CreateChannel["yun", Permissions -> "Public"]

Out[1]=

In[2]:=

listener = ChannelListen[channel]

Out[2]=

打开 Arduino Yun 设备.

In[3]:=

yun = DeviceOpen[ "Arduino", {"/dev/tty.usbmodem1421", "BoardType" -> "Yun"}]

Out[3]=

配置设备，每 0.5 秒向通道发送模拟引脚 A0 到 A2 值.

In[4]:=

DeviceConfigure[yun, "Upload" -> {"BootFunction" -> <|"Code" -> "ChannelSend", "Pins" -> {"A0", "A1", "A2"}, "Scheduling" -> 0.5, "Channel" -> channel|>}]

Out[4]=

关闭设备并拔出，在模拟引脚安置加速计并将区域中的 Yun 关闭.

In[5]:=

DeviceClose[yun]

可视化收到的数据.

In[6]:=

Dynamic[ListLinePlot[ ToExpression /@ Reverse[Take[Reverse[#["Values"]], UpTo[100]]], PlotRange -> {0, 5}] & /@ listener["TimeSeries"]]

Out[6]=
