Do you have a sample udev rule? I looked at the graphlcd ax206dpf driver, it might be possible to extend multiple displays to other userland programs like st2205term.

No, sorry no working udev rule at hand. It was a request from users over at the i-have-a-dreambox forum. Never used different serials myself.
But connecting more than one display works without an udev rule. Libdpf will access the first (by linux) detected display as "USB0", second one as "USB1", etc. The only problem is, that the order of detection may change on next reboot or if a display is connected/disconnected. I would guess that the detection order can be fixed with an udev rule and different serials (anyone done this?).
Another possibilty: let udev assign each display to a device like /dev/dpf0, /dev/dpf1, etc. based on its serial. I think this is much cleaner, but we have to change libdpf for this to work...

Okay, here we go: test firmware for the two different dx21334 dpfs.

@gabychan
Please test the firmware fw_disp_dx21334a_gabychan.zip

@C4Vette
Please test the firmware fw_disp_dx21334b_C4Vette.zip

Hello,

i have a quite different question:

I did svn co of the latest version of lcd4linux, which is quite a little bit newer then the version used in dpf-ax:

1189 vs 1142.

In the newer version of lcd4linux there is also some code for DPF displays.

When i run ./configure of lcd4linux --with-plugins=DPF it starts complaining about missing libdpf/libdpf.h.

According to some googling dpflib/dpf.h should be the right one. But the question is where to put it that ./configure won't complain.

/usr/include/libdpf/libdpf.h won't work.

It's als mentioned to put dpflib.o to /usr/lib.

So my question is, did anyone succeed to compile latest lcd4linux with DPF support?

Thanks for your replies ...

and also thanks to superelchi he helped me with some DPF available in german amazon store :-)

FYI. I bought a DPF from "link-delight-fr" on eBay (item 160792780280) and the "LcdIniTbl" CRC matches the one from the stock "dx21334b" firmware. I flashed the firmware that you made for C4Vette and it works. Thanks.

I managed to find the authors of the patch, see these:
1. lcd4linux changeset
2. lcd4linux mailing list thread
3. patches
The dpf.h is renamed to libdpf.h and this patch expects to find libdpf directory inside the lcd4linux folder. In fact there are more changes to dpflib.c/dpf.h
+int dpf_copy(ADDR dst, unsigned char *src, unsigned short n)

I managed to compile this version of lcd4linux by hand editing. But I think the correct way to do this is to merge the changes back to dpflib in dpf-ax.

Hello ax206term,

thanks a lot for quick reply :-)

Are the any plans to merge this changes back in future?

And just for some basic understanding ... I applied the patch you mentioned to lcd4linux and compared the libdpf.h with the original one ... there are quite some more changes or?

FYI: new version 0.310 in svn.

* Support for frequency controlled backlight.
* New models:
- dx21334a
- dx21334b

@gabychan
@c4Vette
@Tim
I did some fine tuning of the brightness control. The brightness in the test firmware did not match the original brighness (much too bright). Please discard the the test firmware from my earlier post and use the attatched one.

Thanks. I flashed the new firmware but the brightness control is acting weird.

1 -> 2 (gets brighter)
2 -> 3 (gets brighter, after a quick bright flash)
3 -> 4 (gets darker)
4 -> 5 (gets brighter, after a quick bright flash)
5 -> 6 (gets darker)
6 -> 7 (no change)
7 -> 8 (gets brighter)
8 -> 9 (no change)
9 -> 10 (gets darker)
10 -> 11 (no change)
11 -> 12 (gets brighter)
12 -> 13 (no change)
13 -> 14 (gets brighter)
14 -> 15 (gets brighter)
15 -> 16 (gets brighter)
16 -> 17 (gets brighter)
17 -> 18 (gets brighter)
18 -> 19 (gets darker)
19 -> 20 (no change)
20 -> 21 (no change)

The two quick bright flashes also happen when going from 6 to 5 and from 4 to 3.

I know. :-)

These "no change / gets darker / gets brighter" steps are the same with the original firmware (at least on my dx21334) . Seems to me that these frequence controlled backlights are not really a perfect match for the ax206.

The flashes happen only with the dpf-ax firmware. Hadn't find a cure for them until now. But its a small inconvenience, visible only on brightness changes. And - how often do you do this?

If I disable the timer before changing the per/pwm/con values and enable it afterwards then the brightness control acts almost, if not, identical to my stock firmware. I also noticed that brightness setting 20 and 21 use different per/pwm values in my stock firmware than what you use in dpf-ax.

1. Somebody has to work through the changes and then submit the patch to dpf-ax for merging.
2. Likewise, lcd4linux has to be reworked to be consistent with these changes. I prefer the st2205 method of locating the library in /usr/local/lib rather than within lcd4linux
if test "$ST2205" = "yes"; then
   if test "$has_st2205" = "true"; then
      GRAPHIC="yes"
      DRIVERS="$DRIVERS drv_st2205.o"
      DRVLIBS="$DRVLIBS -L/usr/local/lib -lst2205"

$as_echo "#define WITH_ST2205 1" >>confdefs.h

   else
      { $as_echo "$as_me:${as_lineno-$LINENO}: WARNING: st2205.h not found: st2205 driver disabled" >&5
$as_echo "$as_me: WARNING: st2205.h not found: st2205 driver disabled" >&2;}
   fi
fi
The mplayer ax206 patch somewhere in this thread follows a similar approach.

The original fw-dumps for dx21334a&b both had these wretched backlight tables, so I used them. Anyway, I like yours better, even if I see no real difference on my dx21334. :-)
I also added the timer disable / enable to suppress the white flashes. Had this in before but deleted it, because its not a real fix. Instead of white flashes now you have black flashes. :-o But granted, these are much harder to spot.
Fixes commited to svn.

I see no need to patch libdpf.

Every basic function needed to write a lcd4linux driver (or any other) is already there. Wrappers for higher level functions should definitly be done in the driver. Have a look at hackfin's lcd4linux patch (lcd4linux-svn1142-dpf.patch). It already includes the library locating code ax206term suggests.
But - as I said before: integrating dpflib in its current state into an existing project is really a mess (sorry again, hackfin). What we need is to convert libdpf to a shared library like "libdpf-ax.so". This shared lib and its headers can be installed to standard location like /usr/local/lib and /usr/local/include. Did a rough version of this a while ago, but never found the time to finish it (yet)...

Only after this is done it makes sense to think about integrating it into lcd4linux svn.

I've tried various ways to do this and lots of different versions of st2205 etc but there is always something which doesn't detect or compile or something.
Perhaps I just need pointing in the right direction to the current set of instructions, I just don't know. Anyway, any help would be appreciated.

I've got a dump of my firmware and I'm able to use AX206_HW_Bootflasher and ProgSPI.exe to flash it, so even a dump of some hacked firmware would probably help.

Thanks.

Looks like the same dpf I have.
I got it running with ProgSPI.exe and fw_disp_blue.bin
After flashing it should come-up with some eyes :) and a working menu.

Yeah I thought it was close. I'll see if I can generate the file (my linux install just imploded - so recovering that now).
I did manage to load it with a similar one:
"Pearl DPF hackfin portrait 0.12devel firmware.bin"
Using ProgSPI.exe. It displays "something" with the colours all wrong and I think flipped. Pressing menu, gives white screen.

So it was close, but not good enough it seems.

Thanks for the tip...been tearing my hair out trying this.

Do you have the fw_disp_blue.bin file available? That would be one less thing to mess around with.

Thank you!
I finally worked out that you have to select "update" from the settings menu! I now have "eyes" and menu.

Massive thanks guys, you've no idea how long I've been trying to get this working and failing.

I kept getting
sdcc: /usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.15' not found (required by sdcc)
When I tried to build and couldn't find a package to fix it (building on a Raspberry Pi, which is probably half the problem).

Hello, I've got a cheap DPF from ebay (http://www.ebay.com/itm/280828187564) and I can't seem to make it work with any firmware that compiles by default in latest trunk of dpf-ax. The best result so far was that the screen flashed weirdly for a second showing what was in the display's video RAM (or somewhere else) prior to entering bootloader mode from stock firmware and then it went dark-blue/violet. I wouldn't mind some pointers as to how could I go about making the right firmware image for flashing. As far as I understand, this DPF only uses a different LCD initialization procedure than other DPFs and it needs disassembling and manually looking up memory addresses/instructions to properly initialize the screen. However, I've no idea what to change in ./src/ to make it work. Could anyone help me, please?

I've also dd'd the jump table from stock firmware from offset 0x80 to 0x220 in case it'll be needed.

Thanks superelchi, that was quick!
It woked (kind of) but the screen was too dark. I think the contrast settings are wrong or something.

I'm trying to build a new firmware from vendor's official SDK, will report back with my findings.
