Ruby 串行/并行端口操作
我想知道你们中的一些人是否通过 ruby 中的串行或并行端口使用硬件/电路，而不是使用 arduino 或类似的东西，只是通过端口将接收脉冲发送到面包板？或者如果有人知道一个有据可查的图书馆/宝石或关于该主题的优秀博客文章。
到目前为止，我发现有关“原始”端口操作的博客文章非常酷但很短。

这些库看起来不错，但没有很好的文档：

I wonder if some of you are working with hardware/circuitry via serial or parallel port in ruby, not with arduino or something similar, just sending receiving pulses thru the ports to a breadboard? or if someone knows a well documented library/gem or a good blog post on the subject.
So far I've found these the blog post about 'raw' port manipulation is very cool but short.

these libraries seem nice, but don't have very good docs:

我看到你的博客链接，很高兴它被描述为“非常酷”，哈哈，谢谢。
不确定它是否会对您有帮助，但我在该项目的博客上写了一篇（稍）长的关于该主题的文章：

主要是我的 github 帐户的链接，其中包含可能对您有用的示例。
我选择这种“原始”方法是因为代码实际上非常简单（如果你有 Linux）并且对第三方 gem 的依赖较少，但我完全可以理解对一个简单库的需求，并且很想看看你能做什么最终使用。
希望有帮助，祝你好运！
I saw your link to my blog and was happy that it was described as "very cool", lol, thanks.
Not sure if it will help you any more, but I wrote a (slightly) longer post on this topic on the project's blog here:
http://tank.stevenocchipinti.com/2011/11/using-parallel-port.html
Mainly it has links to my github account with the examples that may be useful for you.
I opted for this "raw" approach because the code is actually quite simple (if you have linux) and there is less dependence on third-party gems, but I can totally understand the need for a simple library and am keen to see what you end up using.
Hope that helps, good luck!
