在Ruby中的串行端口通信方面需要帮助 [英] Need assistance with serial port communications in Ruby

问题描述

我需要通过Ruby中的串行端口进行一些通信。从我的研究看来，串行通信的现代图书馆并不多，我可以找到的最新材料是2006年的。有什么我不知道的宝石吗？

I need to do some communications over a serial port in Ruby. From my research, it appears that there aren't many modern libraries for serial communications and the newest material I can find is from 2006. Are there any gems that I'm not aware of?

我最终需要与连接到USB的串行设备（我可以弄清楚端口没有问题）之间保持通信，以进行来回通信（类似Ruby式的伪代码）。

I ultimately need to maintain communications with a serial device attached to USB (I can figure out the port no problem) for back and forth communications like so (somewhat Ruby-esque pseudo code).

def serial_write_read
  if serial.read == "READY"
    serial.write "1"
    until serial.read == "OK"
      serial.write "5"
    end
    return when serial.read == "DONE"
  end
end

推荐答案

串口规格永远不会改变，我不会担心库的年龄。

The serial port specification has not changed in forever, I wouldn't worry about how old the libraries are.

我假设您看到了这篇文章（来自2006年）红宝石和串行端口

I'm assuming you saw this article from 2006 about ruby and serial ports

这是有人得到了 Ruby-SerialPort

Here's someone who got the Ruby-SerialPort library mentioned there to work on macs this year.

还有这是来自ruby的老帖子，内容涉及与Win32串行API的接口。

There's also this old post from ruby talk, about interfacing to the Win32 Serial API.
