My remote control works as a keyboard and I want to change the MythTV mappings to the appropriate keys. For me to do this I need to work out what keypress the remote button relates too.
I have tried to do this through nano (pico), but some are special keys and I get a funny characters in nano. Could anyone suggest a X11 app that will display the keypressed thus I can work out exactly what how to map the keys to the right place.

Does it work in an xterm? If so, just run xd (or something like that, try man -k hex) to hex dump standard input and then press away. man ascii will tell you the ascii code for a given hex value.

Read the topics on the Nova-T remote. What you should look for is to let lirc use dev/input.

I have used xterm previously, but the problem is keys that don't act like normal, like pg up and down, that sort of thing.
I will look into the Nova-T thread and see how I go.
Cheers

Okay here is what I tried.
I did find that my USB remote is set as keyboard as event1. So I downloaded the latest version of LIRC and ran the configure and set it appropriately. I set the LIRC to run at boot and rebooted the computer.
I then start a terminal windows and run irw, but I get nothing when I push buttons.
So I am back again at the beginning.

Girkers, have you checked hardware.conf is set to use the correct event? Also you probably only need to make a new lircd.conf using irrecord

Right, irrecord must be run. Short version of how to do it:
Locate the right eventX using for example "cat /dev/input/eventX". (Note that during boot input devices are dynamically assigned, boot the machine with the device you are normally going to use, then after boot connect any extra devices. For example I always boot without keyboard and mouse.)
Use irrecord to generate a new config file.
Set up lirc using the new config, dev/input driver and the right eventX.
Modify .lircrc if you gave the keys other names during irrecord.

I already have an lircd.conf file from LIRC website and all the buttons have the right names.
I have tried doing the install manually by changing the hardware.conf but again this made no difference. Here are some of my files to help diagnose.
Code: cat /proc/bus/input/devices
...
I: Bus=0003 Vendor=6253 Product=0100 Version=0100
N: Name="Twinhan Tech Remote Control"
P: Phys=usb-0000:00:1d.1-1/input0
H: Handlers=kbd event1
B: EV=120003
B: KEY=800000 0 e0b0ffdf 1cfffff ffffffff fffffffe
B: LED=1f
I: Bus=0003 Vendor=6253 Product=0100 Version=0100
N: Name="Twinhan Tech Remote Control"
P: Phys=usb-0000:00:1d.1-1/input1
H: Handlers=mouse0 event2 ts0
B: EV=7
B: KEY=70000 0 0 0 0 0 0 0 0
B: REL=3
...
This is consistant across reboots, I've checked. Code: # /etc/lirc/hardware.conf
#
# Arguments which will be used when launching lircd
LIRCD_ARGS=""
#Don't start lircmd even if there seems to be a good config file
START_LIRCMD=false
#Try to load appropriate kernel modules
LOAD_MODULES=true
# Run "lircd --driver=help" for a list of supported drivers.
DRIVER="dev/input"
# If DEVICE is set to /dev/lirc and devfs is in use /dev/lirc/0 will be
# automatically used instead
DEVICE="/dev/input/event1"
MODULES="lirc_dev lirc_i2c"
I get the lircd.conf from http://lirc.sourceforge.net/remotes/twinhan/DTV
As writing this post I found that I have a lircd.conf in /etc and one in /etc/lirc directories, funny thing is, it is the same file and I don't remember putting it both places.
Next step

Seriously girkers, try making a new lircd.conf with irrecord. Or at least test making it and only do 1 key. When I was getting my nova-t to work all the ones I downloaded and tried didn't work.

No worries, I will give that a try and see how we go.

I take this silence to indicate success
okay, so I've tried to follow as much as I could. I'm totally green.
1. I'm using the LIRC that came with R5A26. Is that okay?
2. here is my /etc/lirc/hardware.conf
Code: # /etc/lirc/hardware.conf
#
# Arguments which will be used when launching lircd
LIRCD_ARGS=""
#Don't start lircmd even if there seems to be a good config file

# Run "lircd --driver=help" for a list of supported drivers.
#DRIVER="default"
DRIVER="dev/input"

# automatically used instead

Please give my very basic instruction. Like full paths and annoying stuff like that. I don't even know how to insure that lirc will/will not start on boot. (/etc/init/d/lirc is present, but I think there is more to it than that, right?)

BTW, since this thing is behaving like a keyboard, the arrows, help,enter, clear (esc) and number buttons appear to be delivering standard key codes. But the only why I've detected signals from the other buttons is to
xxd /dev/usb/hiddev0
which is not resposive to the buttons that deliver the standard key codes.

In hardware.conf change the MODULES= line to:
MODULES="lirc_dev lirc_i2c"
reboot then try irrecord again
If that still doesn't work try changing it to event3 and reboot (use event3 with irrecord aswell)

Still getting:
irrecord: could not init hardware (lircd running ? --> close it, check permissions)
I tried:
Code: DEVICE="/dev/input/event3"
MODULES="lirc_dev lirc_i2c"
and: Code: irrecord -d /dev/input/event3 /tmp/irrecord
as both event2 and event3, rebooting for both. What does the "check permissions" part of the error mean? Permissions of what? Code: root@mythtv:/home/mythtv# ll /dev/lirc*
crw-r--r-- 1 root root 61, 0 Sep 25 03:01 /dev/lirc
crw-r--r-- 1 root root 61, 1 Oct 1 04:02 /dev/lirc1
srw-rw-rw- 1 root root 0 Feb 1 08:01 /dev/lircd
prw-r--r-- 1 root root 0 Jul 30 2004 /dev/lircm
I don't know where to go from here.
