我正在尝试使用Arduino制作示波器，我上传了我从网站上获取的代码（http://lawrencematthew.wordpress.com/2011/08/30/build-a-6-channel-oscilloscope-with-just-arduino/）您认为代码可以正常工作，但是当我运行代码时，它会给出我的错误。我试图进行谷歌搜索，但没有找到解决方案。我不太了解任何关于处理的事情，我只是主要使用它。我感谢任何人的帮助。
它给出的错误如下： 没有可用的顶点着色器 然后在那下详细的编译器信息是：

我添加时似乎有助于减少错误数量：
import processing.opengl.*;
import javax.media.opengl.*;
除此之外，我完全不知道如何解决这个问题。
