phpRPC + Ruby + Arduino = 远程控制
phpRPC + Ruby + Arduino = 遠程控制LED開關(?)
嗯，我知道這是個很無聊的Sample :P
關於phpRPC與Arduino請自行Google
觀看此demo之前請先安裝另外一篇所提到的serialport
與另外一個Gem
套件：phprpc
在這個範例中，我透過PHPRPC建立一個Server，並且透過RPC呼叫一些method去控制USB Serial Port
而在實現這個demo時，我們必須建立Server&Client兩端
底下是Source code:

代碼:
# Server
#!/usr/bin/env ruby
require 'rubygems'
require 'serialport'
require 'phprpc'
class Cloud
def initialize
@@sp ||= SerialPort.new("/dev/cu.usb
serial-A600bMiv", {:baudrate => 9600})
end
def write(color)
@@sp.write("##{color}")
end
def close
@@sp.close
end
end
def randomColor
r = rand(256).to_s(16)
g = rand(256).to_s(16)
b = rand(256).to_s(16)
r = "0" + r if r.size == 1
g = "0" + g if g.size == 1
b = "0" + b if b.size == 1
color = r+b+g
cloud = Cloud.new
cloud.write(color)
"Color #{color} has been set."
end
def setColor(color)
cloud = Cloud.new
cloud.write(color)
"Color #{color} has been set."
end
def setRGBColor(r,g,b)
cloud = Cloud.new
cloud.write((r+g+b).to_s)
"Color #{(r+g+b)} has been set."
end
methods = %w"randomColor setColor setRGBColor"
server = PHPRPC::Server.new
server.debug = true
server.add(methods)
server.start
at_exit{
cloud.c

1. ruby已成为1.87
2. 必须先安装安装光盘里的新的xcode，在"optional"目录里
3. 可能需要重新安装macport
http://trac.macports.org/wiki/Migration
4. 或者升级macport
http://weblog.rubyonrails.org/2009/8/30/upgrading-to-snow-leopard
$ sudo port selfupdate
$ sudo port sync
$ sudo port upgrade --force insta ......
#一、定义一个类
class Person
def initialize(name,age=18)
@name=name;
@age=age;
@motherland="china";
end
def talk
puts "my name is "+@name+" and I am "+@age.to_s
&nb ......
#一、模块定义及引用，模块就是一段代码，里面有一些方法放一起。
#定义模块用module...end 。模块与类非常相似，但是：
#A) 模块不可以有实例对象；
#B) 模块不可以有子类。
include Math
puts sqrt(91);
module Me
def sqrt(a)
puts a*a;
return a*a;
end
