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]=
