I have tested your utility in Italy.
Is there someting I can check?

Thanks for sharing your work.

Are you using Centrafuse at the same time and if so what is the speed reading showing on it? The code has been changed since the first version but I have not seen what you have describe happening on first version anyway - usually at rest it will hover between 0-3km/h

I have tested the second version too. The behaviour is the same with or without CF running. CF speed is ok, but the speed displayed by your tool is not stable (two digits random numbers) at rest... :-(

Anyone has this behaviour?

What about the Heading - does that display correctly?

I'm in the car testing V2 right now.

I'm getting the same fluctuating speed and direction as mentioned above.

I also keep getting the camera warning despite being nowhere near a camera.

Shame.

Not sure why the display would be showing erratically as described. Have tested on a number of computers with nothing like it occuring.

This version tidies up the error trapping and also has a log window showing raw data. To access right click the Notify Icon and Click Show Log and a window will open showing:
Line number (Reset after 40 Lines)
Timestamp
Validity - A - Good or V - Invalid
Speed - in Knots
Heading - Degrees
Latitude
Longitude

If there is no signal nothing will show in the box and the Speed and Heading will be shown as a "-"

i have only had 2 responses back from people in the Northern Hemisphere saying it is not working. Has anyone got it working up there?

Other Changes:
Error displayed if Port 21 has not been set up as a valid Port.
Camera.jpg - Display Picture for Speed Camera Alert.

Hi AUSMARK,

I have tested your last version with more attention and I found that the speed value it's right (= equal to destinator value) if car speed is > 100 Km/h, is the right value * 10 if the speed is from 10 to 99 Km/h and is a random (?) value if the speed is below 10 Km/h. Does this mean something to you?
I have also a request: could you add an option to disable the heading display?

Thanks!

At very low speed you would have to expect some variation as the error within GPS signal factors in. Will look into the formatting of the Speed Value in the next version.

Will include option to turn off Heading Display and/or Speed Display in next version.

New version 1.0.1.1
- Supports Imperial and Metric
- Can now turn off Speed and/or Heading Display
- Can now change Com Port - Default still 21 - Restart CFSpeed to save changes

In answer to erratic speeds below 100kph - I have not been able to reproduce this except that at very slow speeds and low signal strength the accuracy of GPS does diminish.

Next version should have ability to add a new Speed Camera

To install just replace the old exe file with the new version.

Thanks AUSMARK! I'll test this new version.

About the speed problem I confirm that on my system (XP US last update) CFSpeed writes 805 when the speed is 80(.5) Km/h, 35 when the speed is 0(.35), 120 when the speed is 120, and so on... :-) I's really strange. Could it depend on a localisation setting?

Hi - Yes you are right - the problem is localisation - as soon as I made my computer Italian i experienced the same problem.

Working on a fix now.
