I think I have LCDd and all working.. but I'm wondering about "boot" order for rc5.d
Myth Tries to start now, but requires a second "kick" to get mythlcdserver talking to lcdd or mythfrontend talking properly to mythlcdserver.
I'm not sure which is at fault, but LIRC and LCDd and all that starts at S20.
Any thoughts?
-Ben

I've had this issue before, I bumped it up to something higher, like 95 instead of 20 and all works fine now.

Who's on first?
I have my iMon VFD working with R5D1. If anyone needs a "HowTo" let me know (I thought this was old news)...

I would love a how-to on this, I'm on RE50. I am a bit new to linux, but can get my way around ok, so a step-by-step would be great!

Hi,
I'd like to have this how-to. I need a step by step instructions too (I'm a Linux Newbie).
I have already installed the R5E50 sources. I tried to the instructions on the Venkys site without succes ( http://venky.ws/projects/imon/). I think we need to recompile LIRC but ...
Activate the IR and the VFD is my actual Knoppmyth project.
Thanks
Bob

ErikU and Bob - I am running R5D1, can't say for sure if the instructions will work for R5E50, but I don't know why they wouldn't.
Bob - I long ago gave up on the IR receiver in my LC10M (much too slow, inconsistent results) so I can't help you there.
I honestly did this so long ago that I forget where I got the patch from, but I'm pretty sure it was somewhere on this site: http://swik.net/imon. This may help those of you trying to get the IR receiver working as well. So, instead of a HowTo I'll just spoon feed ya
OK, first you need the patched VFD driver. Download the tarball from my webpile http://www.tbf-investments.com/imon_vfd.tar and save it in your /tmp directory (it's only 102K).
Next, run this code:
Code: cd /tmp tar xvf imon_vfd.tar cd /tmp/imon make echo "lirc_imon" >>/etc/modules modprobe lirc_imon mknod /dev/lcd0 c 180 144 echo "#!/bin/sh" >/etc/rc5.d/S91LCD echo "/usr/sbin/LCDd" >/etc/rc5.d/S91LCD chmod 755 /etc/rc5.d/S91LCD
(You can save this as a script and execute it if you like).
The VFD should display at this point. The S91LCD stuff is to ensure that LCDd is started on a reboot.
The trick here is the tarball includes whatever patch I had found awhile back. This is all I had to do to get the VFD in my LC10M working. Be sure to enable it in KM!

I actually have an LC20M (connects USB), I know the hardware is ok, since it works under windows. I followed the directions but no remote or display..? Anything else to check?

The VFD on the LC10M connects via USB as well. What do the following give you on your system (2 separate commands)?
Code: lsusb lsmod | grep -i imon

Looking back at my script I see I create /dev/lcd0 after modprobing lirc_imon (Ooops!  ). Have you rebooted the machine since running those commands? Or try rmmod lirc_imon and re-modprobing lirc_imon...
Another thing: If you are running R5E50 and have rebooted, udev may have removed your /dev/lcd0. I'm on R5D1 and haven't played with udev before, but there should be a config file to make /dev/lcd0 permanent.

Can you post what you see in the messages file? grep -i imon /var/log/messagesAnd what do you get when you run Code: lsusb lsmod | grep -i imon Bob wrote: In the DMESG, i see port open port close nothing on the VFD. Well, that's good

Hi again,
Yes, it was a typo for the /etc/lcd0 vs dev/lcd0
I make some test with Windows to be sure that the VFD is working. The Imon Windows drivers are really great. The VFD has work instantanely. So my hardware is good.
Now the Knoppmyth side. I applied your code and there is an error on the echo "#!/bin/sh...
Code: root@mythtv:/home/mythtv# echo "Hello" > /dev/lcd0
The rest of the code seem to work but nothing on the VFD Here my infos: Code: root@mythtv:/home/mythtv# lsusb Bus 001 Device 003: ID 045e:00e3 Microsoft Corp. Bus 002 Device 001: ID 0000:0000 Bus 004 Device 003: ID 05e3:070e Genesys Logic, Inc. Bus 004 Device 002: ID 15c2:ffdc SoundGraph Inc. iMON PAD Remote Controller Bus 004 Device 001: ID 0000:0000 root@mythtv:/home/mythtv# lsmod | grep -i imon lirc_imon 16260 0 lirc_dev 16628 3 lirc_imon,lirc_serial,lirc_i2c usbcore 111364 5 lirc_imon,usbhid,usb_storage,uhci_hcd
And the logs: Code: root@mythtv:/home/mythtv# grep -i imon /var/log/messages Jan 21 11:14:03 mythtv kernel: /usr/src/lirc-0.8.1-CVS-pvr150/drivers/lirc_imon/lirc_imon.c: VFD port opened Jan 21 11:14:03 mythtv kernel: /usr/src/lirc-0.8.1-CVS-pvr150/drivers/lirc_imon/lirc_imon.c: VFD port closed
I'm having realy hard time but i have learned how to make cut and paste from xterm.
Maybe with all this info you will find the problem.
Thanks
Bob

My bad, that first echo statement doesn't work  Instead of the 2 echo statements, now that you have Copy-n-Paste working, add the following 2 lines to a file called /etc/rc5.d/S91LCD: Code: #!/bin/sh /usr/sbin/LCDd and make that file executable ( chmod 755 /etc/rc5.d/S91LCD) Bob wrote: Here my infos: Code: root@mythtv:/home/mythtv# lsusb Bus 001 Device 003: ID 045e:00e3 Microsoft Corp.

OK, that looks good. What does your /dev/lcd0 look like? ( ls -l /dev/lcd0) You should get something like Code: crw-r--r-- 1 root root 180, 144 Jan 14 11:25 /dev/lcd0 but with a different date.
Once those 2 things are all set, try rebooting
