| |
| − | ==Features==
| |
| − | ===Basics===
| |
| − | * 32" (diagonal) [[16:9|widescreen]] [[LCD]] television
| |
| − | * Not that heavy for its size (one person can lift it, in or out of packing carton)
| |
| − | Special features and nice touches:
| |
| − | * [[RS232 port]] at the back to allow external control (by LinuxMCE for example)
| |
| − | * Power LED is red on standby, and switches to BLUE when set is on
| |
| − | * Brightness can be instantly adjusted via two remote buttons -- the only thing better would be a photosensor that adjusts things automatically for ambient light (but that's what hacking is all about ;-)
| |
| − | ===Picture fidelity===
| |
| − | * I'm not enough of a video-phile to add to this. Generally, if I get a picture I'm happy...
| |
| − | ===Usability===
| |
| − | * The [[OSD]] UI and remote are excellent. Both the menus and the buttons are laid out sensibly, and the system incorporates a great idea for settings that are cyclic (most are): the first time you press a button (e.g. [[aspect ratio]]), it brings up an [[OSD]] reminder of the current setting; subsequent presses will cycle through the available options. It's simple, and effective at preventing accidental setting changes by a single inadvertent button press on the remote.
| |
| − | Resolutions:
| |
| − | * 1024x768
| |
| − | * 1280x768
| |
| − | * 1360x768

| |
| − | == Adding new template ==
| |
| − | Here is a description of adding a Template for LG LCD TV with serial connections for control. According to the manual the following models should work:
| |
| − | LCD TV MODELS 32H40
| |
| − |
| |
| − | === Specify device data and parameters ===
| |
| − |
| |
| − | On the LinuxMCE admin website go to: Advanced > Configuration > Device Templates
| |
| − |
| |
| − | Select: Manufacturer 'LG', Device Category 'TVs/Plasmas/LCD's/Projectors' and press 'Add device template'
| |
| − |
| |
| − | Description : XXH40
| |
| − | Implements DCE : yes
| |
| − | Command line : Generic_Serial_Device
| |
| − | Device Category AV TVs/Plasmas/Projection... #77
| |
| − | Manufacturer LG
| |
| − |
| |
| − | Also have added following parameters (You need to add them one by one under the header 'Device data'):
| |
| − |
| |
| − | Device data
| |
| − | Current Data Comments Default Value
| |
| − | #37 COM Port on PC(string) The serial port
| |
| − | #76 COM Port ParityBit/Stop(string) Parity/Stop bits (factory defaults) N81
| |
| − | #78 COM Port BaudRate(string) Baud rate (factory default) B9600
| |
| − | #157 Discrete Volume(bool) Indicates if the volume on... 1
| |
| − |
| |
| − | Settings are factory defaults and shouldn't be changed (9600 baud rate, 8 bits, 1 stop bit). Make sure that the check box for Allowed to Modify is checked, so that you can change to the appropriate COM port later.
| |
| − |
| |
| − | === 'Edit Ruby code' (on template page) ===
| |
| − |
| |
| − | ==== 'Add/remove commands' ====
| |
| − | First, I clicked on 'Add/remove commands' and clicked on commands that are supported by device...
| |
| − |
| |
| − | * Ruby Internal Commands
| |
| − | * Standard TV
| |
| − |
| |
| − | ==== 'Add Ruby snippets to commands'====
| |
| − | Edited corresponding Ruby snippets for each command. Basically those are just simple strings that get send on rs232 to take proper action on device according to received command from LinuxMCE... Use the extended editor for the multiline entries (otherwise ruby won't understand it and gives lot's of errors)

| − | == Adding device ==
| |
| − |
| |
| − | This is a simple process that you can now add via the [[LinuxMCE Admin Website]] at '''Wizard > [[AV Devices|A/V Equipment]]'''
| |
| − | === Add device based on created template ===
| |
| − | Just search for the device template that you created and select it from the list
| |
| − | === Specify COM port for it ===
| |
| − | Just tell LinuxMCE which com port to use.
| |
| − | === Assing it to new room ===
| |
| − | Tell LinuxMCE which room to assign this device
| |
| − | === Specifiy Audio pipe connections to inputs on receiver ===
| |
| − | Tell LinuxMCE how you have thing attached to the LG TV and how the LG TV is attached to the computer.
| |
| − |
| |
| − | ''I have it attached via RGB port and I have my cable box attached to AV1 and my HDTV connected to Tuner-Digital input.''
| |
| − |
| |
| − | ==Making Plug&Play==
| |
| − | This is not needed to use the TV, but I post as an option.
| |
| − | Location: /usr/pluto/pnp
| |
| − |
| |
| − | vi /usr/pluto/pnp/20_LGLCD.sh
| |
| − | add the following and then make the file executable.
| |
| − |
| |
| − |
| |
| − | <pre> #!/bin/bash
| |
| − | #Play and Play script for LG TV's Models Numbers:LGXXLB4/5D
| |
| − | #Set ID needs to be set to 01
| |
| − | #Serial feedback is very slow so it requires several seconds to get feedback
| |
| − | #Device Template Number:1905 on my local Machine.
| |
| − | #Serail Command for Power On ka 01 01
| |
| − | #Serial Command for Power OFF ka 01 00
| |
| − | #Returns two different strings depending on whether or not the TV is On or Off, so we will try to turn it ON then resend the ON command as it returns proper string (ka 01 01\r\na 00 OK01x\r\n)
| |
| − | echo "LG TV Detection script queue $2"
| |
| − | /usr/pluto/bin/TestSerialPort -p $3 -P N81 -b 9600 -t "ka 01 01\r"
| |
| − | sleep 5s
| |
| − | /usr/pluto/bin/TestSerialPort -p $3 -P N81 -b 9600 -t "ka 01 01\r" -i 5 -s "OK01x\r"
| |
| − | if [[ "$?" -ne 0 ]]; then
| |
| − | echo "It's not a LG TV"
| |
| − | /usr/pluto/bin/MessageSend dcerouter -r 0 $1 1 806 224 $2 13 "$4" 44 0
| |
| − | else
| |
| − | echo "It is a LG TV"
| |
| − | /usr/pluto/bin/MessageSend dcerouter -r 0 $1 1 806 224 $2 13 "$4" 44 1905
| |
| − | fi</pre>
| |
| − |
| |
| − | the plugin will run the script with 4 parameters: the device id of the plugin, the unique id for this event (the PK_PnpQueue), a path where the device is located (ip address for ethernet devices, serial port for rs232 devices, etc.), and the name of the pnp detection script.
| |
| − |
| |
| − | The detection script should attempt to determine what device template is on the path using any appropriate means. If it finds a match, it should fire a message using the paramters it received, such as this:
| |
| − |
| |
| − | /usr/pluto/bin/MessageSend dcerouter -r 0 $1 806 224 $2 13 "$4" 44 1905(this is the template id for the devicetemplate you created above)
