      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…

      Ciao,
      Michele

        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…

            @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

            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).

                  Ciao,
                  Michele

                    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.

                                  I'm not even sure what device this thing works as… /dev/parport0, /dev/lpt0 or /dev/ttyS0? They all don't work... Ugh...

                                  I can't even get the FreeBSD LCD sample that shipped with my unit to work...  :-\

                                    Looks like it should be on lpt0 from the patch code. Assuming it's on 0x378 on your box.

                                      Hmm… I checked the BIOS, looks like the LCM port might have been disabled. I set the parallel port to 0x378.

                                      This is the output of "cd /dev/":

                                      Not sure what "led" is, but I don't see anything in here interesting…

                                      ...breaking news: The backlight shuts off now when LCDd is started... Not sure why everything else doesn't work.

                                        Holy #$&$ it works.

                                        I love you guys.  :D

                                        I guess if we can move this to 0.5.4, it can be put into lcdproc-dev

                                          Good to hear. Try the sdeclcd driver again now that the parallel port is enabled in the BIOS.

                                            Doesn't look like the sdeclcd works. I think the Lanner version specifying "connectiontype=lanner" means there is something funky with the implementation.

                                            Only issue I see about the lanner driver is that the backlight doesn't timeout (maybe I'm stupid and that's an LCDProc config) and enabling the heartbeat on LCDProc limits the screen updates and actually closes the window the key presses can be detected (I think.)
