Cxx0 Hardware / C700 With Rfid Cf Reader
« on: September 28, 2006, 10:42:26 am »
I've recently started doing some work on RFID and I would also love to get my Z talking to an RFID reader/writer.  Especially because for in the field a self contained reader is easy enough to design but a reader/writer would need something like the Z to be able to make changes.

All of the research I've done points to that none of these tools are working on the Z yet.  I might try to do some work on the software if I can get the hardware to work better on its own first.

User Request for Applications / Educational Titles - Looking For Input
« on: September 28, 2006, 10:16:18 am »
I'm looking for any suggestions on some simple kids titles that I should either port or write.  I've not done anything too graphically intensive.  

I've got a one year old son who plays with my SL-5500, while I use my 860c.  Here's what I'm thinking of so far:
- A basic interface that would be full screen and would allow the volume to be changed with keys.  The cancel key would not close the menu app (he likes to push that key most, it seems) but there would be some way to close it.
- A very basic image matching game similar to some of what is in gcompris.  He could push the screen with his finger.
- A simple paint program that would rotate through colors constantly.  Again finger driven.
- Some kind of graphical program which just made pretty pictures and responded to his finger commands in some way.  Maybe even display pictures of animals and say their names.

Thoughts before I get started?

5x00 General discussions / Pushing Sound Through The Speaker?
« on: March 14, 2006, 07:03:44 pm »
I seem to remember a distro that let you use the speaker that does keyclicks to play other sounds.  In particular I remember playing a movie on my 5500 that I could hear without headphones.

Anyone remember this?  Was it a kernel driver or something?


Accessories / Another Usb Sync/charge Cable Question
« on: September 13, 2005, 07:44:09 am »

I always thought that the sync charge cables between most Zaurii were interchangeable.  In fact on the trisoft and rwsherwood websites they only sell one cable for the various versions.  

I bought a cable from Electro Island which charges, but doesn't sync.  And I've got an older cable from Expansys I used with my 5500 that used to charge and sync but after a few months now only charges.  

I think the real issue here is that a lot of people have had usb sync/charge cables which were defective, and needed to be replaced shortly after purchase.  Make sure you buy from a repuatable vendor who will swap out the cable if you have any problems.  

My suggestion for the US is to try, as he has had positive feedback on this site.

General Discussion / Your old Z
« on: September 13, 2005, 07:37:57 am »
I've got an 860 that I use daily, and a 5500 I use for various technical tasks around the house (wifi scanner, ethernet testing, testing of Z code when the 860 isn't docked)

Right now I'm trying to use the 5500 as a baby monitor.  I'm using Palantir on the server end, which allows me to view the webcam above my son's crib.  Currently I use the java palantir client for the Zaurus although I'm trying to port the QT palantir client at the moment.  There's no audio, as normal baby monitors are cheap and have better range, but otherwise it works well.

Qt/Qtopia / Dialog Sizing

I think I know what you are asking.

In the past when I have needed to do what you want I've used:
Code: [Select]

Does that help?

Qt/Qtopia / Changes To Compiler On 64bit System?
« on: July 03, 2005, 10:11:27 pm »
Thanks for your advice Melee, but unfortunately that doesn't work.  I think I would need to recompile gcc296 to work on 64bit or to find a library that would allow for the 32bit compiling to work correctly.

I setup an FC4 virtual image and that is working just fine.  Not as nice as compiling in my normal environment but perhaps I'll want to move it to another server some day...


Qt/Qtopia / Changes To Compiler On 64bit System?
« on: June 28, 2005, 04:43:48 pm »

Yes, the fact that I am running a 64 bit OS is my problem, although that is what I alluded to in my first post. Running a 64bit version of fedora means that all compilers, programs, libraries, etc make use of 64 bit code, with the exception of any programs I've installed that use 32 bit compatibility libs - this lets me run 32 bit code too or run programs installed from 32 bit rpms.  (I have a bunch of libraries where I have installed 32bit and 64 bit versions, and the OS takes care of knowing which one it wants for a particular app)

The main issue is that all my memory pointers, for example, use 64 bit addresses.  The cascade effect on any code I'm compiling is that it is looking for 64 bit object code.    

This is where I'm getting a little confused.  When I installed the compiler for the Z it is expecting to create for a 32 bit target.  Now that I have a 64 bit target I was hoping that I could install some kind of compatibility lib to make it work, but I'm not even sure if that is even the solution.

And I don't want to install a 32 bit OS because that was the whole point of buying a 64 bit box.  I've got a good stable system right now except when using the compiler needed for the Z.  I might instead install a virtual machine or something and go that route.

I'm having a problem compiling on my box.  I think I have found the source of my problem, but have got no idea about a solution.

I'm running FC3 on an amd 64bit cpu.  I installed the cross compilation rpms, the same as I did on my old 32bit cpu.  When I try to compile anything for x86 I get errors during assembly, such as:

"{standard input}: 35: Error: suffix or operands invalid for 'push'"

If I do a cross compilation to ARM everything works just fine.  Therefore my suspicion is that the problem is due to the change in my chipset, but I have no idea what kind of compiler options to change, or if I need to install updated binaries of some kind.

Any ideas?

Cxx0 General discussions / What's Better? Sl-6000 Or Sl-c860?
« on: February 02, 2005, 10:51:41 am »
I've got a c860.  

While I wouldn't mind having the Wifi and bluetooth built in, I honestly don't use them that much right now. So the 6000 is attractive, but only marginally.

I really prefer my c860 since the keyboard is excellent.  It makes quite a bit of difference for me since I can type with my thumbs more comfortably.

I seem to remember that the memory layout/proportions are different between the models too.


Windows Issues / Syncing Problem - Z5600 And Outlook 2003
« on: January 17, 2005, 04:54:34 pm »
I use the docking station that came with the Z...I guess that's USB, right?
[div align=\"right\"][a href=\"index.php?act=findpost&pid=62185\"][{POST_SNAPBACK}][/a][/div]

Yeah, that is a USB connection.  However I now have noticed that I am much more likely to be able to sync if I don't use TCP/IP for the connection (not the default anyway).  It still fails occasionally, but works much better if I do USB direct I/O.

Do you sync using the USB I/O or TCP/IP?  

I've never been able to get my Z to sync since we moved to 2003.  Now I'm at a different company, also running 2003, and I still can't sync.  

I've installed the 860 drivers (because I have an 860, of course) from the ZUG download section, and the 5600 intellisync from which is Intellisync 3.2e.

Any suggestions?

(UPDATE: Isn't that they way it always happens?  I switched over to USB I/O and it works.  However my original question still stands as I would rather leave the Z in TCP/IP mode if possible.)

Texas / Is there really a Texas ZUG?
« on: January 12, 2005, 03:48:51 pm »
Howdy (seemed appropriate for the ZUG),

I've just moved to Houston.  Any Z users here?  It would be great to meet up because I am looking for tips about where to buy accessories, etc.

Cxx0 Hardware / Operational Issues
« on: November 29, 2004, 09:09:45 am »
I've left my 860 on for a week or more.  There are no heat issues or similar, although sometimes I have problems where the screen won't turn on even though I can see everything fine on VNC.  

I expect you won't have any problems, especially if you check on it from time to time.

Qt/Qtopia / Using "cancel" In Qtopia Apps
« on: November 23, 2004, 03:37:48 pm »
Good timing.  I was just about to ask a question regarding closing apps, but this might be the answer I need.

Please tell me what you think:

My apps save conifguration values when the app closes down.  I use the destructive close, not really knowing how it works, but because a posting I read somewhere said to use it.  This means that if the user closes an app with the X on the title bar, the app calls all the destructors.  

However, if the user closes the app with the cancel button, I don't get my destructors called and my apps don't save any configuration information.  Is this a good time to use the code you pasted above?  Or is there a better way to do it?
