Thread: How-To use lirc to control receiver and tv power

ever wish tv , receiver power on , off pc , screensaver? these scripts , instructions can.

there assumptions here , have tailor setup example of mine.
importantly i'm using mythbuntu , xscreensaver screensaver used in distribution script has been written for. have conf files devices want control , scripts setup home directory , devices.

on fun stuff.

you'll need conf files devices want control.
http://lirc.sourceforge.net/remotes/
if can't find device here or in /usr/share/lirc/extras/transmitters/ can create 1 using irrecord beyond scope of how-to. i'll reply if ask though.
if have more 1 device, need more 1 transmitter thing i'd stress can copy , paste devices 1 conf file lirc load.
should example master.conf below.

code:

put file in /usr/share/lirc/extras/transmitters/
if you're wondering how use, master.conf file want use

code:

sudo cp master.conf /usr/share/lirc/extras/transmitters/master.conf

now configure lirc knows transmit.

code:

sudo gedit /etc/lirc/hardware.conf

and edit transmitter_lircd_conf

code:

# /etc/lirc/hardware.conf  #  #chosen remote control  remote="windows media center transceivers/remotes (all)"  remote_modules="lirc_dev mceusb"  remote_driver=""  remote_device="/dev/lirc0"  remote_socket=""  remote_lircd_conf="mceusb/lircd.conf.mceusb"  remote_lircd_args=""    #chosen ir transmitter  transmitter="microsoft windows media center v2 (usb) : kenwood"  transmitter_modules="lirc_dev mceusb"  transmitter_driver=""  transmitter_device=""  transmitter_socket=""  transmitter_lircd_conf="master.conf"  transmitter_lircd_args=""    #enable lircd  start_lircd="true"    #don't start lircmd if there seems config file  #start_lircmd="false"    #try load appropriate kernel modules  load_modules="true"    # default configuration files hardware if  lircmd_conf=""    #forcing noninteractive reconfiguration  #if lirc reconfigured external application  #that doesn't have debconf frontend available, noninteractive  #frontend can invoked , set parse remote , transmitter  #it populate other variables without user input  #if configure lirc via standard methods, sure  #to leave set "false"  force_noninteractive_reconfiguration="false"  start_lircmd=""

we need edit lircd.conf include master.conf

code:

sudo gedit /etc/lirc/lircd.conf

code:

#this configuration has been automatically generated via  #the ubuntu lirc package maintainer scripts.  #  #it includes default configuration remote and/or  #transmitter have selected during package installation.  #  #feel free add custom remotes configuration  #via additional include directives or below existing  #ubuntu include directives selected remote and/or  #transmitter.    #configuration windows media center transceivers/remotes (all) remote:  include "/usr/share/lirc/remotes/mceusb/lircd.conf.mceusb"    #configuration microsoft windows media center v2 (usb) : master:  include "/usr/share/lirc/extras/transmitters/master.conf"

ok cool lirc configured. reboot , see if lirc can send ir commands.
hope have ir transmitter setup in front of ir eye of device controlling.
using format irsend directive remote code example

code:

irsend send_once vr4085df key_power

should net desired action. (fyi remote , code names in conf file.)
if not fix lirc config before continuing.

now scripting goodness.
lets start xscreensaver.sh

code:

gedit xscreensaver.sh

code:

#!/bin/bash  cd /home/gilson585/  xscreensaver-command -watch|  while read status;    case "$status" in      blank*)        /home/gilson585/sysoff.sh;blanked=1;echo $blanked > blanked        ;;      unblank*)        /home/gilson585/syson.sh;blanked=0;echo $blanked > blanked        ;;    esac  done

please edit that 3 instances of home folder point yours.
fix permissions

code:

chmod 777 xscreensaver.sh

now put in startup applications.
in mythbuntu thats applications > settings > session , startup
in ubuntu thats system > preferences > sessions (or startup applications)
create new entry, name it, , use example below create command.

code:

/home/gilson585/xscreensaver.sh

now lets add scripts xscreensaver.sh calls

code:

gedit syson.sh

code:

#!/bin/sh  cd /home/gilson585/  blanked=`cat blanked`  if [ $blanked -eq 0 ] ;  	blanked=1;echo $blanked > blanked  else  	irsend send_once vr4085df key_power;irsend send_once kenwood_rc-r0813 power;blanked=0;echo $blanked > blanked  	sleep 1  	irsend send_once kenwood_rc-r0813 cd/dvd  fi

obvious edits required here, 1 home directory, devices , codes sent.
should added startup applications.
think know how
fix permissions

code:

chmod 777 syson.sh

code:

gedit sysoff.sh

code:

#!/bin/sh  cd /home/gilson585/  blanked=`cat blanked`  if [ $blanked -eq 0 ] ;  	irsend send_once kenwood_rc-r0813 power;irsend send_once vr4085df key_power;blanked=1;echo $blanked > blanked  fi

again same obvious edits before.
fix permissions

code:

chmod 777 sysoff.sh

we call script upon shutdown within lirc init.d script.

code:

sudo gedit /etc/init.d/lirc

now if search stopping remote control daemon happen across section of code.

code:

		if [ "$start_lircd" = "true" ];  			log_daemon_msg "stopping remote control daemon(s): lirc"  			start-stop-daemon --stop --quiet --exec /usr/sbin/lircd  			log_end_msg $?  			[ -h "$old_socket" ] && rm -f $old_socket  			[ -h "${old_socket}1" ] && rm -f ${old_socket}1  		fi

add su gilson585 -c "/home/gilson585/sysoff.sh" gilson585 username looks this

code:

		if [ "$start_lircd" = "true" ];  			log_daemon_msg "stopping remote control daemon(s): lirc"  			su gilson585 -c "/home/gilson585/sysoff.sh"  			start-stop-daemon --stop --quiet --exec /usr/sbin/lircd  			log_end_msg $?  			[ -h "$old_socket" ] && rm -f $old_socket  			[ -h "${old_socket}1" ] && rm -f ${old_socket}1  		fi

awesome if reboot should turn on , off wanted, same goes screensaver state changes. if not check work.
if don't use xscreensaver script won't when screensaver state changes. can either rewrite sys or use xscreensaver.
