I finally got around to upgrading to R6 and have now updated my R5.5 based how-to for LinHes (aka R6). The old How-to is at: http://knoppmyth.net/phpBB2/viewtopic.php?t=19574

In some ways this has become simpler but there are a few issues to navigate.

Summary of changes over R5.5:
1) minimum lirc is now 0.8.6 (LinHes 6.01 uses 0.8.5-CVS)
2) use released version of lcdproc-0.5.3 as opposed to the patched 0.5.2
3) lirc 0.8.6 makes changes to the lircd socket and lircd.conf file.
4) The stock LinHES hardware.conf will now work

PREPARING:
---------------
Log in as root (it is easier).
First let's set up the build environment this will also support custom packaging but I needed it for make and ensuring the compilers are up to date.

You can use any reasonable working directory such as "/home/youruser" which I will use for examples.

LIRC:
-------
Remove the old Lirc first:

As a safety check look for any remnants of lirc_imon as it will interfere if it is present:

If you see one then move it. For example:

Get and unpack the latest lirc:

Configure it by executing the following and choose "Driver Configuration" then "USB Devices" then "Soundgraph iMON IR/LCD". Once chosen then save & exit (do not run config!):

Now configure with the following option enabled to ensure things go to the right places:

And make and install it:


Lirc 0.8.6 makes two important changes relevant to this how-to:
** /dev/lircd has moved to /var/run/lirc/lircd
However, not everything knows this in our beloved LinHES so you will need to make a link between the two. I edited "/var/service/lircd/run" and added the following line just after "LOG=/tmp/lirc.log"

unless you do the above things like irexec will not work!

** The second important change in 0.8.6 is that the imon devices will generate a 64 bit IR code rather than a 32 bit version. You will need to modify your lircd.conf accordingly. Just like in R5.5 this file should have the path "/etc/lirc/lircd.conf". If you have an existing lircd.conf then you can modify the header. Referencing the lircd.conf in my 5.5 how to, the header section changes from:

to:

which in essence adds the needed 32 bits of data.

If you need a lircrc file use the one in the 5.5 How-to and place it in /home/myth/.mythtv/lircrc and link it to /etc/lircrc (which is a work around for irexec; I haved filed a flyspray bug on this).

Alternatively I have added a more recent complete set from my environment as of 28Mar-2011 in this thread: http://mysettopbox.tv/phpBB2/viewtopic. ... 053#132053

LCD PROC:
--------------
Obtain the latest files:

Now you will need to configure this to compile the needed drivers. I'm lazy so I compiled them all:

Now you need to modify /etc/LCDd.conf (if it ended up somewhere else then you should copy it to /etc) as follows:
Under [server], change:

**NOTE DriverPath could also be /usr/lib/lcdproc. Check to see which one was created. Different people have seen different results. Make install should show you which one it did.

After you have tested your set up, uncomment:

so that the LCD start screen doesn't show up under normal usage. You can do this later after you have checked everything works as this screen is useful to ensure you have done things correctly to this point.

Ensure LCDd will start on boot:


Now finally, go into Myth and configure it to use the LCD for rmessages (in the set up menus)

Restart your LinHES box and the LCD should light up with the default messages and eventually with the myth information (usually date and time to start).

Thanks for doing this. A very good how-to.

I had some issues, but they could have been related to my setup. I did not have 'lcdproc' installed before, and do not use a remote (I have a keyboard). So that could have changed a few things.
I did the "make install" as root.

Some hints for others:
1. Following the steps, my install put LCDd into "/usr/local/sbin". The default "/etc/sv/lcdd" (for 'add_service.sh lcdd') points to "/usr/sbin". Editing "/etc/sv/lcdd" fixes this.
2. LCDd.conf was not installed in "/etc", and was actually in in "/usr/local/etc". Two possible solutions: (1) edit "/etc/sv/lcdd", or (2) copy to "/etc". [I chose option 2]
3. I chose 'tinker' in MythTV configuration for LCD, and then hand edited LCDd.conf .

Mykola

You are right. I guess my notes were not complete. I'll modify the above.

to get the right path, you can "--prefix=/usr" to the configure command which should solve item (1).

As for item (2), this did not happen to me. However, you are correct, our architecture expects it in /etc so that is where it should go.

Thanks for the update!

Hi christ,

Thanks for your great guide. I was looking for that since my R6 upgrade.

I own a Silverstone case GD01 with this imonlcd



I have two problems with the LCD (Just one now)

First problem the LCD is not very bright. I cranked up the contrast to 600 in LCDd.conf. It help a bit but not su much. It was lighter under R5. Any hints?




Second one
I'm just seeing the big clock with the heart animation. The LCD don'T show menu navigation like in R5. Any hints?

EDIT: Add Setting 'LCDServerHost' to 127.0.0.1 in the settings table fixed it.



PS Do you check this link with an imon server? http://www.ronfrazier.net/mythtv/0.21/i ... nLCDTweaks



It's great to have my LCD back in service after a so long time.

Thanks for helping

You're welcome, I figure I need to document it for myself anyway so why not do it publicly so others can benefit.

ffdc is one of those bizare codes from iMon which has many types of devices associated with it. On mine it is an LCD on others it is a VFD.

Not sure what to tell you. I think it is the same on mine as before. I just double checked the driver and the only options it really has are contrast(0 to 1000) and backlight(on/off). You can fiddle with the contrast as higher is not necessarily better and the effect is not necessarily linear.


This is strange as the default lcdd.conf I had included this. Where did you find your lcdd.conf?

I've interacted with Ron before but I had not seen those notes. Just be careful because as he says at the top, it is dated. lirc has changed significantly in 0.8.6 as it relates to iMon.

Hi christ,




I used the default lccd.conf per your instruction. The modification i have made is directly in the mysql database with Toad for mysql. I found this info in thread after a googled it.

The solution was to had this record on a fresh R6 install (Not R55 upgrade to R6)
Add Setting 'LCDServerHost' to 127.0.0.1 in the settings table fixed it.


Thanks again
Bob

Interesting. So on a completely fresh install you would do:
where YourHostName is the name of the machine with the LCD.

I don't have this in my database for settings so there is probably another reason why you are seeing this issue.

In your /etc/hosts file do you have only:
plus some trailing comments?

I have this in my /etc/hosts

So yes my /etc/host is different than your.


Other important thing i have upgrade to 0.22 Mythtv with the how to from the forum. My initial google is effectively related with 0.22 Is it a coincidence? Is it required for 0.22?
http://www.gossamer-threads.com/lists/mythtv/users/402902#402902

Thanks
Bob

Oooo, you always want a localhost.

You can still have your hostname def... but for all apps to be happy looking for a "host" named "localhost" it should be assigned to 127.0.0.1.

But 127.0.0.1 also can have your hostname (INCLUDING "localhost")

I have a stock etc file and it reads:

127.0.0.1 MythTV localhost

Odd. Where did this come from?

I am also on 0.22 from the testing repo. bkamen is correct and to my knowledge the only thing in your hosts file you should need is the format I specified above.

I just double checked my master backend and one of my dedicated front ends and they are all this format.

And what's dangerous here (I remember fixing stuff like this all the time) where someone would edit /etc/hosts and then change the IP address outside of normal system admin routines that would allow the new assignment of the interface IP while the old hosts file still existed.


So now when an application asks the resolver to contact "myhost" at an old address -- it contacts the wrong IP or a nonexistant one. Hehe.

So that stuff needs to be considered carefully.

Hi,

Thanks for reply

I normalized my hosts file with only 127.0.0.1. For now all is working good.

I don't remember when and why i hardcoded the machine Ip Adress there.

My LCD is working great. I tested with XBMC and the LCD is still working when i activate it under XBMC. I don't have tested if i remove the entry in the database. Anyway it' not hurting.

Next step i will try to make the Imon remote pad to work.

Thanks for your help
Bob

I have thought I would try this how-to tonight. It is well written and easy to follow, but at then end my lcd didn't work and my mce remotes don't work. I don't have a lot of experience, but I like to try things to learn. Sometimes not the best plan. The remote worked 'out of the box' on install, is there a simple way to make them work again?

I tried changing the reciever in the LinHES settings section
I tried changing the lirc to driver to mceusb

I guess I shouldn't have started this, I don't really have much time for this these days, but would really like my remotes to work again. Any help would be awesome.
JJ

roofchop,
I will apologize in advance if I'm slow to respond as I'm very ill this week.

changing the driver to mceusb isn't going to help because you likely have some form of imon hardware.

The above procedure is only for "Antec Fusion Black 430 (aka Veris)(with LCD)". My guess is your Antec Fusion may be different. Are you sure it is a Black 430?

Can you also output what you get from lsusb? Mine is:

That is a fast reply in my books....Thanks. My case is an older Antec fusion, I was presuming it would be similar to get the VFD to work. Mine definately doesn't have the IR receiver. Now I am just hoping to back peddle and get the mce remote to work. Here is the out put from lsusb:

Thanks for the help christ......JJ
