Contents
RubySerialIOConnectionWrapper
The connection object, is the exported (already opened) connection to the device. It can be either Serial (or USB Serial) connection or a network connection (in this situation you need to specify host IP and port to connect).
It's usually accessed via conn_ variable.
Methods
- Send (<string>) : will send the string to the device
- Recv (<count>, <timeout>) : will put return received data (either the count was reached, or the timeout)
- RecvDelimited(<delimiter>, <timeout>) : will return received data until the delimiter was found
- Reconnect() : will close and then reopen the connection to the device
- Close() : will close the connection
RubySerialWrapper
This class is the equivalent of DCECommandImpl, is the one which implements commands and most of the time your code will run in this context
Methods
- SendCommand (<command>) : send a command (kind of DCEmessage, may be command or event)
Members
- parent_ : parent device
- device_ : access to the device itself
- children_ : list of children
RubyDeviceWrapper
The wrapper for DCEDevice, will have all devicedata and other stuff
Members
- devid_ : Device ID
- devtemplid_ : Device Template ID
- devdata_ : a map <int, string> with device data
- parent_ : parent device
- childdevices_ : a map <int, RubyDeviceWrapper> of child devices.
RubyCommandWrapper
A wrapper over DCEMessage, not quite right called Command, because we can use it for both commands and events.
Members
- devidfrom_ : device id of sender
- devidto_ : device id of receiver
- priority_ : message priority
- type_ : message type (1 = command, 2 = event)
- id_ : message ID (commandID or eventID)
- params_ : map <int, string> whith parameters
Usage samples
To send a command
cmd = Command.new(devidfrom, devidto, priority, type, id); cmd.params_[x] = y; SendCommand(cmd);
To receive some data of unknown length
recv=""
while(true)
buff=conn_.Recv(128,100)
if(buff.length() == 0)
break
end
recv = recv + buff
end
To process command for child device
dev_slot = device_.childdevices_[cmd.devidto_].devdata_[12]
case cmd.id_
#power on
when 192 then
conn_.Send("ON "+dev_slot+"\r");
#power off
when 193 then
conn_.Send("OFF "+dev_slot+"\r");
end
