Comment 2 for bug 138247

I have a post in the ubuntu forum relating to this.

I was able to get it to work in feisty to drive a homemade ir blaster.

Here's what I did:

HOW TO MYTHTV LIRC SERIAL IRBLASTER

Making lirc work in any version of Ubuntu seems more difficult than necessary.

This has been adapted from another how to located here:

http://losdos.dyndns.org:8080/public...ting_LIRC_Make

The above post and version did not work on feisty --

Heres how to create ledxmit on Feisty:

Here it is.

Before starting make sure some necessary utilities are installed:

Code:

sudo apt-get install build-essential
sudo apt-get install linux-headers-`uname -r`
sudo apt-get install setserial

INSTALLING

Get LIRC version 0.8.2 from the LIRC download page
Code:

cd ~
 mkdir myth-ledxmit ; cd myth-ledxmit
 wget http://internap.dl.sourceforge.net/sourceforge/lirc/lirc-0.8.2.tar.bz2
 bzip2 -d *bz2 ; tar xf *tar

Create this shell script that will create a new version of lirc called ledxmit that is independent of the regular lirc.

gedit ~/myth-ledxmit/myth-ledxmit82-feisty.sh

cut and paste the following into the file
Code:

#!/bin/bash
#
# myth-ledxmit.sh

# by jds-myth !at! losdos.dyndns.org
# portions by rwraithr !at! iwamble.net

echo "$0: Running make"
make
echo "$0: Complete"

Make it executable
Code:

chmod 755 ~/myth-ledxmit/myth-ledxmit82-feisty.sh

Run the script
Code:

~/myth-ledxmit/myth-ledxmit82-feisty.sh lirc-0.8.2

Change to the myth-ledxmit.WIP directory
Code:

cd ~/myth-ledxmit/myth-ledxmit.WIP

Install
Code:

sudo make install

NOTE: All of the newly created LIRC executables are copied by "make install" to a separate tree under /usr/local/lirc-ledxmit.
No MythTV nor Linux configuration files are changed during this process.

SETTING UP

CREATE /etc/ledxmit.conf will need to be setup with your remote codes

see this link http://lirc.sourceforge.net/remotes/

You can create your own if your cable or sat box is not listed.

Mine was a visonetics and contains the following:

Create /etc/modutils/lirc-ledxmit

Code:

sudo gedit /etc/modutils/lirc-ledxmit

Insert the following for COM2 Serial IR Blaster
Code:

# FILE: /etc/modutils/lirc-ledxmit
alias char-major-72 ledxmit_serial
below ledxmit_serial ledxmit_dev
# !!! note DEFAULT is COM2 !!!
# for COM1, simply uncomment the following:
# options ledxmit_serial irq=4 io=0x3f8
# for COM2, do nothing, or uncomment the following:
 options ledxmit_serial irq=3 io=0x2f8

Save the file

Add the new modules list

Code:

sudo /sbin/update-modules

Make the device node
Code:

sudo /bin/mknod /dev/ledxmit c 72 0

Disable the regular serial port driver
Code:

sudo /bin/setserial /dev/ttyS1 uart none # (IS for COM2 use /dev/ttyS0 for COM1)

Install the ledxmit_serial module:
Code:

sudo /sbin/modprobe ledxmit_serial

Make sure it's working
Code:

sudo lsmod | grep ledxmit

you should see the following:

ledxmit_serial 7104 0
ledxmit_dev 8560 1 [ledxmit_serial]

Start up the ledxmit daemon
Code:

sudo /usr/local/lirc-ledxmit/sbin/ledxmit-ledxmitd -L /tmp/ledxmitd.log

(this starts the deamon ledxmitd and creates a listening socket at /dev/ledxmitd)

Verify both ledxmit-related devices are now present and have the proper attributes:
Code:

ls -sl /dev/led*

you should see:

0 crw-r--r-- 1 root root 72, 0 May 4 20:57 /dev/ledxmit
0 srw-rw-rw- 1 root root 0 May 4 20:57 /dev/ledxmitd

Create startup scrit
Code:

sudo gedit /etc/startledxmit.sh

Insert the following into itL
Code:

/sbin/update-modules
/bin/mknod /dev/ledxmit c 72 0
/bin/setserial /dev/ttyS1 uart none # use this for COM2
/bin/setserial /dev/ttyS1 uart none # (or use /dev/ttyS0 for COM1)
/sbin/modprobe ledxmit_serial
/usr/local/lirc-ledxmit/sbin/ledxmit-ledxmitd -L /tmp/ledxmitd.log

save the file and exit gedit

Make it executable
Code:

sudo chmod 755 /etc/init.d/startledxmit.sh

Set the script to start
Code:

sudo gedit /etc/rc.local

add the following line before exit 0

Code:

/bin/sh /etc/init.d/startledxmit.sh

save the file and exit gedit

TEST IT

This is assuming you have a visionetics remote devicedescribed in /etc/ledxmit.conf

The command below would turn a visionetics device on or off

Code:

/usr/local/lirc-ledxmit/bin/ledxmit-irsend SEND_ONCE visionetics power

Your remote device will be different so adjust the above command

Change Channel Script.

To get MythTv to use the Blaster create a change channel script. --> See it here:http://losdos.dyndns.org:8080/public...ting_LIRC_Make
