LCD screen for your dockstar (cheap! <$5)

Hi, All

I have a Sytronix device which I bought specifically for the hack, and was pleased to find it has the same identifier as expected. From lsusb...
Bus 001 Device 018: ID 1403:0001 Sitronix Digital Photo Frame

I found it had showed up at /dev/sdb and the hack script resulted in a screen showing 'baks r ok', but I was surprised to find, that it reported...
$ ./hackfw.sh /dev/sdb
...
"Sorry, I couldn't find a matching device profile"

I then followed the instructions at...
http://forum.doozan.com/read.php?2,2435,2439#msg-2439
...using the latest .deb for the cc65 tools which no longer seem to be available via public subversion.

It seems to be talking to the device. However, the script also reports failure, finishing with the lines...
Locating CMP_VAR1 & CMP_VAR2...
Eeek! expected single match but found 0 - dont know what to do!

Any ideas what I can do now to try and proceed? I'm pretty sure it's from the right family of displays, but the default approach doesn't seem to be cutting it and the steps for a new hack are failing too.

The original firmware backup generated by the hackfw.sh script is attached to this post.

Thanks superelchi, great news.

You tested if it works with the DX21334?

Thanks to all.

FYI: new dpf-ax version 0.3 in svn.

Its now possible to build 2 different firmware versions:
- 'Developer' version: firmware with same features and look as pre-0.3 versions ("Blue Screen of Hack").
- 'Display' version: firmware for use as a status display (lcd4linux, vdr, etc.) with bigger font, new menu and selectable splashscreen.

@petergunn

I would like to report a problem I am facing with st2205term/ax206term. For the 5x8 font defined in fonts.txt, the last column of # (column 5) along the width isn't used hence it is behaving more like 4x8. This results in truncated capital letter Y and letter w among the character set. I edited fonts.txt manually for these 2 characters to use 4x8. Fonts.txt is created by makefonts.c. I'm using a 128x128 frame.

What is the best way to fix this problem? Thanks in advance.

lcd4linux then run but there was nothing on the display; just a white screen.

The dpf dims a little when lcd4linux starts, but thats it. No info or whatever....
Also, the dpf can no longer put put off, is that 'normal' ?

Did I forget something or maybe did something wrong?

I fixed the problem with a strategic placement of fseek
fseek(fd,7,SEEK_CUR);
if (fread(d->data,1,sz,fd)!=sz)
in load_font function. And for fonts.txt, between z and { characters, I added empty lines. I will wait for petergunn to comment on this.

Little further:

after flashing with "fw_disp_linkdelight.bin" it almost worked. For a moment I could read something like "LCD4LINUX" and then the screen filled with text and bars (Yeahhhh...) but it was all mirrored. Even the menu kind of worked but also mirrored :(
I've read a topic that this happened to others and the advice was to use an older dpflib. I tried that but can't get it compiled.


The original FW: DX 27893 dump

Bought at: DX.com

As far as I know it is an 1.5 inch 128x128 and the SPI tells me:

Cmd-9f: ID:0xef401400
Cmd-ab: ID:0x13131313
Cmd-90: ID:0xef13ef13
flash ID Winbond 25q80

If anyone has this dpf working I would be glad to hear how you got it going.

Ed

Edit:
Wow! Don't know why, but it works!
Again I compiled and tried to flash but now the restore.py gave me trouble. But because the bin's compiled OK I copied them to Windows (ohoh) and started to try them all with "SPI Programmer". The second one was a hit: "fw_disp_blue.bin" gave me "the eyes", great! Tried the menu-button and got a readable menu. Then started lcd4linux (hehe, back at Linux, pff) and lots of info readable on the display.
Thanks for this very nice hack!

Try the attached file. It uses lcdblit.s from agk_violet and lcdinit.s which I created from lcdinitbl_tmp.txt. I modified dev_mode to 2 to enable identify.py's devel mode.

Hi,

thanks for the dx27893. I have one of these myself but forgot to add it. :-o
Will be available as new model "dx27893" in the next svn commit.

Just finished adding a new feature for those, who want to connect more than one display at the same time: USB iSerial Number adjustable in dpfs menu. Now its possible to identify each dpf by a unique serial number, e.g. in a udev rule. Will need a little more testing - but I hope to upload it in the next days...

BTW: works also with dealextreme model # 27894 (blue).

Thanks ax206geek for your help and trouble.

New display to toy around with!

Bought at: DX.com

FirmWare dump: full.bin

It's a 2.4" AX206 320x240
I've first made a dump and then tried all available FW's. The dpf seems to run because linux recognizes a "USB-display" when plugged-in.

In USB-mode lsusb shows: Bus 002 Device 023: ID 1908:0102 GEMBIRD
and in flashmode: Bus 002 Device 024: ID 1908:3318 GEMBIRD

SPI Programmer shows:
Cmd-9f: ID:0xc84014c8
Cmd-ab: ID:0x13131313
Cmd-90: ID:0xc813c813
flash ID in channel 1 is Apple 25Q80

FW fw_disp_focal.bin almost works: it uses 1/4 of the screen and all the lines are in reversed order; from bottom to top that is.
Even the menu kinda worked but has black bars between the items. That was a lot better than the original menu because that one was in Chinese!

Via linux:
python restore.py ../src/fw_disp_focal.bin -f

ubuntu:~/dpf-ax/trunk/fw# ./hiddetach
Detaching dpf at 2-2.1:1.0... done.
root@ubuntu:~/dpf-ax/trunk/fw# python restore.py ../src/fw_disp_focal.bin -f
Found AX206 DPF (bootloader)
Manufacturer: Apple
Size        : 1 MB
Erase full flash...
Flashing sector 0...
Flashing sector 1...
Flashing sector 2...
Flashing sector 3...
Flashing sector 4...
Flashing sector 5...

Same result and after a reset of the dpf it doesn't start anymore.

Has anyone had more luck with this one?

Hi, thanks,

Do you mean with "is the same" that it is an original FW dump?
Then that won't change much because I made a dump myself as you can see above via "FirmWare dump: full.bin".
Or is your dump a hacked one and working with lcd4linux?
Re: LCD screen for your dockstar (cheap! <$5)
May 23, 2012 08:28AM
If the original dump, I can not help you over the DX does not work with lcd4linux.

Right. Both are DX #21334 but have different firmware. AND: tried to flash C4Vette's dump to my 21334 (= same firmware as gabychan's). Not working. :-(

Did you try the pearl or pearl_landscape fw? I'm asking, because your original fw-dump at https://www.dropbox.com/s/mt6hfwyucnbxxbh/full.bin works on my pearl dpf...

Hi Sergio,

What fw-type did work for the 33624? if you send me the CRCs or a dump of the original fw I will add it to the list of known dpfs.

How do we use this? Are we supposed to create a udev rule to name each device uniquely and then run the appropriate userland programs?

Exactly. Its only useful if you want to connect more than one display at a time. If all dpfs have same serial, they are detected in random order. For example: my ax206dpf graphlcd driver for VDR supports up to 4 displays which can be logically arranged to simulate a bigger display. Say: 2 hor landscape x 2 vert landscape = 640 x 480 pixel or 4 hor portrait = 320 x 960 pixel. By assigning different serials and an udev rule you can make sure first display ist upper left, second upper right, or whatever.

BTW: got dx21334 working. Needs some polishing, but will be ready in a couple of days (I hope).
