C1000/3x00 General discussions / Usb Vga

hm - will this driver and software work under pdaXrom? Does the driver need kernel sources in order to be compiled (is it a kernel module or a user space program)?

And: would it be possible to buy an entire batch of these devices? Maybe 10 pcs.?

Actually, the Japanese author used this [a href=\"http://www.winischhofer.at/linuxsisusbvga.shtml]Austrian site[/url] in English for compiling the driver. As far as I can see, it's a kernel module. On the author's homepage you can see some technical details in the readers' comment section; just scroll down the page. Maybe someone can figure out what these data mean.

As for the second question: I ordered my device via Amazon Japan, and I have no doubt that there are still many more available. You may check it yourself here, but it's in Japanese, of course.
By the way: The original idea of this device is to have output from one source on up to three screens at a time, so they have three subtypes (each with a different colour) that can be chained. For our purpose, any of them would do (I bought the blue one, because of its nice colour).

I should have read the Japanese homepage more carefully from which I had taken the USB-VGA presentation soft. Actually, some of the features I requested are already implemented. So here's an overview of its functions:

-- After choosing your pics (BMP, JPG, PNG), use the left and right arrow keys to rotate them if necessary.
-- For manual output to the VGA adapter, push the space key.
-- For the automatic slide show, there is a special tab.

The author adds that you should remove the USB host cable only after shutting down Vga presentation.

He thinks it may be possible to doublebuffer VRAM to prepare data for the next slide before it is sent to the adapter, making it possible to create effects like wipe and resolve. I have no clue whether that can be done?

Anyway, the source files are here for the presenter and for the driver.

Meanie your 9,800 yen toy was the USB to VGA device?

I was also wondering if anyone has seen this little “handy” device

http://www.chait.net/index.php?p=572
or this
http://www.gizmodo.com/gadgets/top/micromi...tics-154041.php
Has anyone been successful in getting the USB to VGA adaptor to work reliably (not necessarily for any full motion video, but maybe for typing/presentations/photo-slideshows?)
[div align=\"right\"][a href=\"index.php?act=findpost&pid=143248\"][{POST_SNAPBACK}][/a][/div]

Yes. I connected my C3200 running vga-presentation 1.0.1 and using a Kairen USB 2.0 VGA Adapter to a standard data projector, and it worked flawlessly. It takes about a second for the screen to display, but once displayed, it's really working and looks very nice in various resolutions. Technically, everything works just fine.

The only thing is that vga-presentation in its current state only supports automatized slide shows. It's not possible to control them manually, thus making it virtually impossible to use it for presentations. What we need is

-- Manual control for browsing slides (using the arrow keys) (that's a BASIC request!!)
-- Zoom in/out functions (would be nice).

Another option would be to modify photostorage or some other soft that can manipulate images to support output via USB. Maybe that's even simpler ...

Anyway, it's definitely worthwhile giving it a try -- perhaps Meanie could do it? (At least, please update vga-presentation to include manual browsing.)

Zaurus - pdaXrom / Problems Installing Pdaxrom

« on: October 21, 2006, 03:37:38 pm »

Wow, this was really scary ... Leaving the Zaurus without battery for some days, pushing Fn-D-M, then hitting reset with the battery lock open really did the trick. Thank you, Antikx. My C1000 is back to life again ...
Lesson learned: Stay calm, take your time before writing off your Z -- and don't meddle with operating systems you don't really understand. "A cobbler should stick to his last."

Zaurus - pdaXrom / Problems Installing Pdaxrom

« on: October 16, 2006, 12:05:25 am »

Hi,

I've the same problem as Antikx with my C1000. So after bricking it, I waited until the next morning and tried Fn-D-M (simply pushing D-M does not work). Nothing happens; the restore diaglogue doesn't show up. Just to check the CF, I tried it again with my C860. D-M worked instantly on the C860, but Fn-D-M doesn't work at all.
Is there any chance that there is a key combination for the restore command other than Fn-D-M?

Edit: The main problem seems to be that I cannot power up the C1000. Pushing OK before and while plugging in does not help.

Accessories / Qpegps Problems

bkudria,

Thanks for your welcome. That your CF starts flashing means it is working and getting a fix. Have you already tried zGPS (http://www.travellingkiwi.com/zgps/zGPS_Download.html)? I know there are no maps for it, but at least it will give you lat/long -- and you can use it to see if the problems lies with qpeGPS rather than gpsd.
On the other hand: It really seems that OZ and gpsd don't like each other. Maybe you should consider reflashing the ROM and reinstall everything. With Sharp or Cacko ROM, everything should be fine ... but that's up to you.

Best,
Pazu_Z

Accessories / Qpegps Problems

Have you tried running gpsd from the Konsole without running qpeGPS? If not: After inserting your GPS-CF into your Zaurus, its LED should be lit (constant red). Run "gpsd" from the Konsole. After warming up (can take several minutes), your card should get a fix and the LED should start flashing. This should prove that gpsd can connect to your card.
If no flashing occurs:
(1) Make sure that your card is in an environment where it can easily get a fix. I.e., go outside, stay apart from tall buildings and trees, and do not move for some minutes; even better, connect a reradiating antenna or the like to your CF. I virtually NEVER use my card without an external antenna because (esp. in an urban settlement) it is very likely not to get a fix without an antenna. If it gets a fix and the LED starts flashing, you know that your card is working.
(2) Make sure your baud rate is detected correctly. What you wrote about the identifier string after you insert your card seems as if upon insertion it is recognized as a bluetooth card. In this case, it is necessary to suppress this automatic recognition mode. Do as I have advised in my anonymous workaround (to which Silvio has already hinted) and outcomment bluetooth device recognition. When the baud rate is too high, there is no way gpsd can handle your GPS data.
(3) Only after you are positive about getting the correct baud rate and running gpsd from the Konsole you should worry about qpeGPS. If you are using an openzaurus ROM, chances are high that it won't support qpeGPS. In this case, consider switching to another ROM like Sharp or Cacko which are positively compatible.

Good luck,
Pazu
