Share My Creation PL2303 USB-GPS-stick - Software is available

Hi all,

I've finished my App PL2303 Mock Location Provider!

If you are interested in using a USB-GPS-Stick on your Advent-Vega, POV mobii or Viewpad, then you should hav a look at Market

https://market.android.com/details?id=de.esolutions4you.mlprovider#?t=W251bGwsMSwyLDIxMiwiZGUuZXNvbHV0aW9uczR5b3UubWxwcm92aWRlciJd

or

https://market.android.com/details?...GUuZXNvbHV0aW9uczR5b3UubWxwcm92aWRlcmRlbW8iXQ..

Now you can use an USB-GPS-stick on your devices usb-host-port.

The app was made for NAVILOCK NL 464 US - stick, but should work with every GPS-stick/-mouse, based on a
sserial To usb interface PL2303...

The costs for such a GPS stick/mouse varies from about $ 20,00 to $35,00.

For using my app no kernel-driver- support is needed. The driver stuff is buildin into the app and is loading on the fly.

Tested under VegaICS... with' GPS-Status and Tools', 'GMaps', 'Navigon' (100% working).
If the app runs in background - all GPS based apps get location data, as like a buildin GPS was activated!


The DEMO version is limited for 10 minutes of use - as often as you want.

Looking nice! How did you do the view with the GPS satelites? It looks superb!

Hi COBRAsoft,

thanx for the reply...

Satellitedata from NMEA contains elevation and azimuth (in degrees) info about the satellites. These degrees-data have to be converted for showing in
Polar-x-y-coordinate-system like


Dim el,az As Double
el=Elev(I):az=Azim(I)
r =90-el
theta=90-az
theta=theta *3.14/180

x=centX+(r*Cos(theta))
y=centY+(r*Sin(theta))

so you have the xy-coords for showing like in my app. But the x-y-coords have to be corrected for every quadrant (0°-90°; 91°-180°; 181°-270°; 271°-360°)

Then the sat graphs (drawCircles, and drawTexts) can be done...
... without java - all to be done b4a

BTW: also the sensor-data for the car level graphics where
dificuilt to correct.

Hi bistra

Looks very well designed. Congratulations!
Sorry for my ignorance, what is the advantage of using the GPS stick over the internal GPS? Accuracy?

By the way,

theta=theta *3.14/180
x=centX+(r*Cos(theta))
y=centY+(r*Sin(theta))

you can save the first line if using:
x=centX+(r*CosD(theta))
y=centY+(r*SinD(theta))



Edit: Question re USB stick answered. I just saw your app in the market.

 

[COBRASoft]

Thx! I got this working and showing nicely now .

Hello,
I want to use your work to install android on my shelf but I can not download the demo version on Andoid market because it is not compatible, you can send me a demo to the test.
thank you

Hi bistra,
good work!! Please, can you explain was you have done or what procedure you followed to place the drivers on the fly (buildin) in your app?

Thanks and regards

Hi,

sorry for the silence, I had a trip to egypt.

The solution to implement the driver stuff is based on agrahams PL2303 lib project: http://www.b4x.com/forum/additional...es/11449-pl2303-usb-rs232-adaptor-driver.html

This made it possible to use the serialadaptor without kernel driver...

I like the UI, looks pro

Just out of curiosity, what method did you use for drawing stuff? a bunch of views, a canvas and manual drawing? transforms?

Hey I think Erel was talking about champ720 - not you. By the way, I too have yet to buy B4A so am I not allowed in this forum? I thought only libs forum was off limits for unregistered users

 

[Erel]

My message was for champ720. Sorry for the confusion.
