XDA mini exec to GPS device dev

Hi all,
I am for Uni looking into using a GPS device (just a receiver) to pass your location to a PDA and with some work on some software on the device do some calculations and useful stuff re where you have gone, how fast etc. But the app on the PDA must be custom written
All i need from the GPS device is location (in longitude+latitude?) and this would be queried about every second.
a) how easy is it to get such an output from a receiver without a lot of premade software overhead?
b) just how accurate can GPS be? i read about 10m but down to 2/3m with WAAS?
c) anyone know of any good documentation on using GPS output for a PDA app?
d) any advice on good GPS devices that can do just this but as accurately as poss. i hear about the ability to get down to a few inches but this isnt publically available? (maybe wrong there)
any help or pointers would be very, very much appreciated.
Andy

Most GPS units send navigation data using the NMEA 0183 protocol, which is text-based (and thus easily parsable). Since you mention the XDA mini exec, I assume you're looking at Bluetooth GPS units -- these units will look like a COM port to the XDA, so you can use standard serial comms code to receive the NMEA data.
If you look around the net (e.g. google, sourceforge.net) you should be able to find a number of Windows applications that do what you want. Most of them will have been written for big Windows, but should be easily portable to the XDA platform.

question about using GPS with the TYTN

Hello
I own an HTC tytn, and I want to do the following:
record a video from my car, with real-time GPS coordinates being printed at the bottom of the picture.
Can a combination of some GPS receiver and tytn do this ?
Thank you

The problem won't be the GPS receiver, but the camera software. The build-in software can't do that. And a third party software would have to support the TyTN camera.

You can record the video with the phones camera (note the time you start recording), and be running a GPS message recording software. then you can use a video editor software in your PC to spuerimpose the text (gps coordinates) in to the movie.

ok thanks -- I think I may just splash out on a video camera with built-in GPS (not cheap), unless the HTC device with built-in GPS (Artemis ?) somehow does it ...

Silly question, why do you want to do this?
Depending on your answer you may find www.mp3car.com an interesting place to vist.

I am working on a large building site, with structures only partially built.
I am trying to show the status of the project to clients by taking a film of the site as it is now, with exact GPS location shown at all times
I woulf then be able to relate exactly what is shown on the film to a modelisation of the fully completed project that we already have.

Fair enough, I saw the Car mentioned and thought you migt be trying to have a video black box in your car, a common idea and one that is being acheived by putting a PC in your car. Hence the link to www.mp3car.com.
I wish you luck in your seach.

Help! Dead HTC Prophet or Wizard?

My fr****g mobile technician baked my wonderful (TI OMAP 850 processor) while trying to solve the signal fault during reballing
Now its completely Dead. It was a gift... (crying...)
So Anybody with dead HTC prophet or wizard hanset or pcb (motherboard) especially those with useless ones for them, want to help please contact on the following:

Im poor guy, cant pay much. My pocket would prefer those with big hearts to give away for free in order to help.

Modding the X1 hardware for tv-out :)

Hey guys!
I know this has been up before, and I've read pretty much every thread regarding the non-existent TV-Out function on X1. But it has made me curious enought to want to attempt a mod if such a thing is possible.
What I understand the X1 has the hardware for TV-Out, but not the functionality implemented. So somewhere along the hardware line, the function is disabled on purpose/not enabled. Chances are, HTC saved in a few cents on the connector itself for example, and that's where the missing hardware line is
Now, most people say the X1 shares the hardware with X2, I'd like to know to what extent and if someone has pictures of an opened X2 to share, it would help out alot. Specially pictures around the 3,5mm connector and connections around it, but also the pictures of the entire mainboard.
If I can find an easy enough way to resolder some new connector/parts, I will def. do so, with full documentation over how to do it. I say harder things have been accomplished before. It all comes down to the differences/similarities in X1/X2 hardware.
PS. I might be taking water over my head here, but I'm one of those guys who got his X1 on day 1, trusting the words of SE about TV-Out, DLNA etc etc. And if there is a 10% chance to achieve this, I will try it.
Thanks for any help in advance

Come on dude you can do it :O
And if it worked i'll donate you for sure

Support you ^_^

uuh..
Hey Zoonie,
i wouldn't say it's impossible, but it's some hard piece of reverse engineering the hardware of X1.
From my point of view somebody has to rip off the MPU and the PM chip and trace the dedicated pins/signals to find out if there's a connection to these signals somewhere on the mainboard. That's the first part
Once you know how to attach some hardware to the signals, you'll need some driver code implemented to support TVout on X1
Anyway here's a basic schematic of TVout for MSM7200!
Have fun,
scholbert

Go for it! Love the effort.
Doesn't the touch pro have TV out? I would think it would be better to try to copy that, since it's the same processor and both HTC manufactured.

Is GPS broken? Please help!

For the first time wanted to make use of GPS in my HTC Leo. However it desn't seem to function at all!
Tried on many (installed as NatveSD) Android ROMs, and also on WM6.5 "Energy" which is in the NAND.
Please, any idea?
Probably a hardware problem. As I remember: few years ago changed the mainboard and maybe during this procedure forgot to connect some cables or sth simillar...
However now I hardly remember even how to open the phone's case...
Please provide with some schema, how to disassemble the HTC Leo and where to look for GPS module!
P.S. The phone's whole other functionality (except GPS) is perfect!
---------EDIT:
Video instructions from here helped me to disassemble the phone, however GPS module and its cable look well. Well, what to check next?
In general, HOW to TEST GPS module hardware from within working ROM? At home it is rather hard to catch satellite signal through the window...
HOW LONG need Leo's GPS hardware read pure sat signals (without internet support)?
