      @stephenw10:

      Here's a suggestion, while reading through some other bootup scripts I found this:

      
      // Do not process while booting
      if($g['booting']) 
      	exit;
      

      Perhaps we could use this somehow to limit the number of reloads? Of course it could easily stop it loading at all.  ::)

      Steve

      It's on dansguardian as well but I did not saw changes on bootup time or times it tries to restart daemon.

      What I did was changing reload option to stop and start.

      I'm not sure about That but it looks like pfsense bootup script calls sync_package function for every xml file on package. Dansguardian has about 20 XML files and It's boot takes more then a minute in start / stop calls.

      Something I'll try is to do not stop/start daemon if uptime is less then 01 minute for example or check if last stop/start call has less then x seconds.

        I have a test driver with LED support. It's been tested some on X-Peak and X-Core-e models, but there is code for X-Core as well. The updated FreeBSD driver is here:

        https://github.com/downloads/fmertz/sdeclcd/sdeclcd.so

        Once up and running, telnet to lcdproc (pretend to be a client) and type

        telnet localhost 13666
        hello
        connect LCDproc 0.5.5 protocol 0.3 lcd wid 20 hgt 2 cellwid 5 cellhgt 8
        output 1 <—Short red blink about every 4 seconds
        success
        output 2 <—Short green blink about every 4 seconds
        success

        The output logic is this: we have 32 bit to work with, and we need 3 states (Red, Green and off). This is 2 bits. So, in 32 bits, I have 16 time slots to work with. So, basically, code in the LED sequence of colors you want to see (Red, Green or off) and keep filling in the groups of 2 bits by shifting. the sequence just repeats indefinitely.

        Worksheet:
        XXXX XXXX XXXX XXXX, X is 0,1, or 2, and represents 2 bits

        0000 0000 0000 0001 is slow short blink red
        0101 0101 0101 0101 is fast short blink red
        0011 0011 0011 0011 is medium medium blink red
        0000 1111 0000 1111 is slow long blink red
        0000 2222 0000 1111 is slow blink alternating between red and green, and off in between

        The representation above needs to be made decimal for the “output” command. Sequence is about 4 seconds.

        Thanks for letting me know if this works out for everyone. Would be nice to work this out into the PHP client, too.

          @easyhugo:

          Hi Guys

          Is it possible to ad this Lcd to

          http://allnet.de/1577.html?&tx_mmallnetproductplugin_pi1[showUid]=421433&cHash=949c8a38a8
          ftp://212.18.29.48/ftp/pub/allnet/utility-server/fw8888/lcm_server_1.0.tar.bz2

          i,m trying this for some time but with no success, see other posts from me

          thx max

          Hi Max (easyhugo),
          it's impossible to know for me which driver this LCD panel uses… do you know the chipset? Can it use one of the drivers already made or you need another driver?

          Ciao,
          Michele

          Hi
          sorry but no driver work with this display, it does not work without these lcm server.

          @stephenw10:

          My German is very bad!  :-[ (Only beaten by my non-existant Italian!  ::))

          However, according to [url=http://www.ipcop-forum.de/forum/viewtopic.php?f=22&t=26948#p231301]this post by IPCop ledgend Wintermute the display in the FW8888 is an LCM-162.

          This doesn't appear to be supported directly by LCDproc but this blog post seems to show it is possible. That's quite old now so support maybe better integrated.

          What drivers/versions have you tried?

          Steve

          Edit: This post confirms this.

          and yes wintermute is an excellent ipcop programmer, but ipcop is not an freebsd os so i cant copy the files .
          i have tried to copy the lcm to the pfsense and change the config files but with no success.
          my test with these lcm if i tried the dev version was not born  :D so at now i will connect the guys from allnet how this lcm will work
          the answer i would then post

          thx

          edit:
          from the lcm pckage:

          Make commands:
               Static binary:
                    gcc –static -o lcm_server lcm_server.c
                 
               Dynamic linked binary:
                    gcc -o lcm_server lcm_server.c

          Execution command:
               lcm_server /dev/ttyS1 "Banner"

          Command FIFO:
              /var/run/lcm_cmd

          Available commands:
                    Clear -- Clear the LCM display
                Home -- Set the cursor back to row 0, column 0
                Display {on/off/nocur} -- Turn display on, off and on without cursor
                BKLight {on/off}      -- Turn LCM backlight on and off
                Setpos {0~1} {0~15}    -- Set the cursor position to row and column
                Write {text}      -- Write the text to LCM start from
                          current cursor position
              Examples:
          echo "Display oncur" > /var/run/lcm_cmd
          echo "Setpos 0 0" > /var/run/lcm_cmd
          echo "Write test message" > /var/run/lcm_cmd

          Key FIFO:
              /var/run/lcm_key

          Available keys: UP, DOWN, RET, ESC

          Example:
          cat /var/run/lcm_key

          Note: There is no key de-bounce mechanism on LCM.
                Multiple key response may happen while receiving keys.

          hi

          the guys from allnet are not the fastest, no response to my mail from 18.2.2012
          so google is now my friend angain to my problem with these lcm server on fw8888

          in found an interesting site http://www.tecnowledge.net/2009/06/getting-lcdproc-to-work-with-an-lcm-162-freebsd/
          how the managed these lcm server in freebsd
          this description are from 2009 with an lcdproc version 0.5.2 but now im not sure if these changes are now included

          thx max

            In a parallel discussion we have established that the lcm-162 is in fact almost identical to the firebox lcd (or at least the nexcom display is).
            Try using the firebox sdeclcd driver and see if you get anything at all.

              Execution command:
                  lcm_server /dev/ttyS1 "Banner"

              This tells me the interface is serial, not parallel. Good old RS-232. My SDEC LCD driver will not work.

              Looking through the code here:```
              ftp://212.18.29.48/ftp/pub/allnet/utility-server/fw8888/lcm_server_1.0.tar.bz2

              
              It seems like the commands for the LCD are the "usual" set (same as SDEC LCD, and possibly HD44780). Being serial interface, you can give a shot to the HD44780, part of lcdproc. You will have to read the documentation for the driver to properly configure it for your display. The reward is that, once working (if it does), then clients like lcdproc itself, or the pfSense PHP client will work, too. Good luck, and keep us posted.
              
              PS: [http://www.tecnowledge.net/2009/06/getting-lcdproc-to-work-with-an-lcm-162-freebsd/](http://www.tecnowledge.net/2009/06/getting-lcdproc-to-work-with-an-lcm-162-freebsd/) is for a parallel port interface, not serial.

                Hi fmertz,
                  well, if the command/behavior is the same, maybe the sdec driver could accept the port as parameter from the client (there are already serial and parallel ports). Just an idea…

                  This would require new code. The parallel interface is driven directly with in/out machine language commands. Serial ports are typically coded with more abstraction, i.e. treated like files. At this point, let's see if the HD driver will do…

                      Hi Steve,
                          I did this change, but I didn't notice any difference on my system (verified from the system.log file), the service is synced 2 times but run only one.

                      Btw, can you apply this change to your "lcdproc.inc" file:
                      Line 525 becomes:
                      if(is_service_running(LCDPROC_SERVICE_NAME) && ! $g['booting'] ) {

                      if this works for you I will release a new version with this change!

                      Thanks,
                      Michele

                        Steve,
                          also, can you check in your /usr/local/etc/rc.d folder if you have a second .sh file running LCDd at startup? The one created by the package is "lcdproc.sh".

                        Thanks,
                        Michele

                          I've only recently stumbled upon this thread and it caught my interest.
                          I'd just like to see throughput on a panel.

                          This thread is huge, but I still can't find a recommended panel that I can easily order (say ebay).
                          I found mention of U204FB-A1. but all I can find is the A2 model of it, and that one does not mention lcdproc (where the a1 specifically says lcdproc).
                            Can someone recommend a cheap, easy to order panel that just works?

                          The idea is interesting to say the least.

                            Hi Tester,
                              well… I cannot recommend my panels because I had a bit to complain with the supplier (they are not precise, when I bought them, the main picture on ebay was the panel with the frame, frame that they didn't ship. When I bought a case it was not precise for my panels. When I complained with them they just said a kind of "that's it", and so on), but at least their stuff worked for me. Also, consider that this forum is not a marketplace, and I think it's better to avoid to turn it into one.

                            So, after this introduction, I was buying two of this ones:
                            http://www.ebay.it/itm/20-4-LCD-Smartie-Display-Board-UART-USB-PC-Edition-III-/350546524199?pt=LH_DefaultDomain_0&hash=item519e337827

                            made by this company: http://www.sureelectronics.net/

                            Consider that I was buying them last year, so was a different hardware version, but I think the "sureelect" driver should work also with this new release of the panel.

                            A little disclaimer:

                            • I am not swearing this will work;
                            • I am not taking any reward from that company;
                            • I am not related to that company (and responsible for any issues you could have with them: billing, payment, shipping, damaged items and so on);
                            • I am just saying "in my case it worked".

                            but if you want to try to spend about $30 to try them (about 20 Euro) it might work. I don't think there is nothing cheaper on the market (at least last year I was searching and searching).

                              I was looking for something that mounted in a drive bay slot.
                              for example.

                              http://www.ebay.ca/itm/U204FB-A2-8-USB-HD44780-204-Blue-LCD-Smartie-Computer-Case-Bay-Drive-PC-Modding-/220978640726?pt=LH_DefaultDomain_2&hash=item33735a7756

                              otherwise I'd jump on your suggestion and give it a try.
                              I'd just like to have something clean looking in the slot…

                              Any thoughts on the item above, or another item that mounts in a drive slot?  No commitments, it's cheap and it seems like a nice toy to play with :)

                                Hi,
                                  yes, it looks nice, even better than mines! On the paper it should work (to tell you for sure I should try one, but for that price it worth a try).

                                The only positive consideration to have it external, is that I am using HP servers to run pfSense and I have an active care pack. If something happens to the server, it's better the HP tech won't find anything "not HP" inside the case. Also, if some short or whatever happens to the panel, it does not compromise the server.

                                Ciao,
                                Michele

                                  THis might be related to the LCM-162 talk above, but I have no idea…

                                  Been working on getting the Lanner LCMs working. I got some official code from Lanner, but it's for lcdproc-0.5.2. Of course it's outdated, but I figured I'd at least get it working before I try to move to the latest. I assume this code is for the lanner "standard" LCM, but maybe it's not...

                                  Using lcdproc-0.5.2, I used the attached Lanner patch files (remove .png, etc). Patch works great, "compile" works great.

                                  When I start LCDd with the driver, I get:

                                  Could not open driver module server/drivers/hd44780.so: server/drivers/hd44780.so: Undefined symbol "hd_init_lanner"

                                  Obviously, something is wrong with the patch code, but I can't figure it out (hd_init_lanner seems defined) or understand why Lanner would release broken code.

                                  I'd appreciate any help possible, I'd be willing to toss some bucks someone's way if they get my Lanner LCMs working.

                                  edit: since my code is broken, see fmertz's post for the driver

                                    Seems like the code in the new source file is not getting linked in the library (.so). Try:

                                    make distclean
                                    

                                    This should scrub the existing build files, then recompile again.

                                      Hmm, just tried it now, I did:

                                      make distclean
                                      ./configure –enable-drivers=all
                                      make all
                                      make install
                                      LCDd -c ./LCDd.conf

                                      Gets the same error. :(

                                          Well, it works in that it doesn't crash - but there is no change to anything with the LCM.

                                          How should I go about making sure the driver is even compatible? Check the wiring diagram with the h44780-lanner.c file?

                                          The connector is very similar to the Firebox connector. It's like a small parallel port.
