我是这个论坛的新手,也是Processing的全部内容。 我有一个具体的问题要问你,非常感谢你的时间和想法!
如何将我的Arduino与Ethernet Shield连接起来,从传感器获取温度值,以便将它们看作处理脚本? 在一个直接的Arduino脚本中,一个获取值,从以太网屏蔽连接到服务器并做自己喜欢的事情。我已经完成了。
在我的情况下,我希望Arduino只运行从传感器读取模拟输入值的脚本。 有可能吗?
我已经使串行连接工作并通过usb读取值,但是使用以太网屏蔽?如何获得arduino读取的值没有USB /串行连接?
PS。我正在使用WAMP服务器等,Windows 7
我正在尝试从http://arduino.cc/en/Tutorial/UDPSendReceiveString进行arduino和处理的UDP连接脚本示例,但是
1)我不确定这是否是我需要的,
2)我已从防火墙端口6000,8888中排除了我的测试,并将我的Arduino的IP地址放在Arduino脚本中,将“localhost”放在Processing脚本
为了更好地使用此处而修改的代码

将这些值读入文件并使用该文件将数据发送到处理中。 http://py.processing.org/reference/createReader.html

很棒的计划。只有一个问题。它在我的系统上完美运行。我用你的Arduino草图装载了我的Arudino Uno R3并加载了Processing sketch。工作就像一个魅力,第一次尝试。没有更改我的Arduino,Windows系统,处理(2.0.3),网络等
你可能有Arduino板问题(不太可能)或以太网屏蔽问题(遗憾的是,更有可能)。您可能遇到网络问题(甚至更可能)。
尝试Wireshark。你真的只是猜测,直到你看看Wireshark输出。请注意,Wireshark有过滤器。你需要它们。过滤掉所有非UDP流量。
