Vag-Scope Heads Up Display / Front End - Page 2

Yeah, thanks for the pic, but not really the vag scope I had in mind.

This looks like engine stats. I wanted to see the vag scope for something ending in an "-ina"

Sorry, your project looks great. Just messing around.

That costs extra

guino: I was able to figure out how to create the object. I suspect I am going to have trouble with looping, but I want to play with it a bit before I bother you. Basically I am not sure how I am going to have it continuously loop until the back button is pushed on the skin, I'll play with this before I ask you to look into it

Great work!! This is exactly the application I have been looking for / planning to implement. The one thing that I am mostly interested in is the MPG, is it instantaneous or is it an average? I could help you do the logging if you want...

As I live in Finland I would like to get the values in metric units, could you specify in your code more exactly where the conversions is done so that I can comment it out in my version.

Have you tested with older versions of VAG-COM?

Once again, great work!!

Thanks tom. The converstions are actually left in code and commented since I figured people would want the metric version at some point. I will be including all the code when i release it so all you will have to do is change the name from <variable>Conv to <variable> and you will get the metrics. To have proper units show on the RR screen you will need to edit the .png that I will include (so you have all the layers) to contain the correct text.

The MPG is a variable average that you can set easily in code. What I do is I keep a counter from 0 to 100 and then each check cycle (the delay is easily changed by changing the Thread.sleep() call...I currently have it set to 250 ms) the counter increments. When the MPG is checked the counter takes counter % numMPG. If this is 0 then it enters that loop, updates the MPG field with the new MPG / numMPG. otherwise it simply updates a MPG stored value so that you get the average over that period of time. Right now I have it updating every second. I do it this way because the MPG is wildly variable and If you updated it every 1/4 second it would be nearly useless. I'll probably make the update longer before I am done. If you wanted you could easily run this .exe in the background the entire time and stick the mpg on most any window, I would do that but right now I'm just wanting to get it to work

I have it working in RR now (I think, have not had time to test it in my car yet)...I'm just trying to get RR to run the .exe. I will be posting about that next.

Ok, so I believe I have the communications working, but I've run into a bit of a problem. I cannot seem to get RR to run my .exe. Right now I have the Video button on the main menu as the button I'm using (I'll be changing the main menu pretty drastically). The Command on the button is "LOAD;VagScope.skin;C:\Program Files\RoadRunner\VagScopeMod.exe;VagScope"

Unfortunatly the above command does not seem to run the .exe. I don't believe it is a problem with the .exe because when I click video and then go run the executeable by hand it works fine. Can anyone help me with this?

On a side note: I have also tried this;

"LOAD;VagScope;VagScope.skin;C:\Program Files\RoadRunner\VagScopeMod.exe;VagScope"

Thanks all.

In the how-do-i-launch-application-its-own-skin-screen thread it says that it should be:

"LOAD;appsname.SKIN;appsname;C :\Program Files\appsdir\appsname.exe;App Name 2.1","appsname"

neither of these are correct by the specs

Quote:

"LOAD;VagScope.skin;C:\Program Files\RoadRunner\VagScopeMod.exe;VagScope"
or
"LOAD;VagScope.skin;VagScope;C:\Program Files\RoadRunner\VagScopeMod.exe;VagScope;VagScope "

it should be

"LOAD;VagScope;VagScope.skin;C:\Program Files\RoadRunner\VagScopeMod.exe;VagScope"

As for the MPG average, the average is resetted everytime you restart the application, right? I would like it to be manually resettable.

puter · 02-19-2008, 03:46 PM

Ya, that didn't work for me.

I also tried:
"LOAD;appsname.SKIN;appsname;C:\Program Files\appsdir\appsname.exe;App Name 2.1","appsname"
and
"LOAD;appsname.SKIN;appsname;C :\Program Files\appsdir\appsname.exe","appsname"
and
"LOAD;appsname.SKIN;appsname;C:\Program Files\appsdir\appsname.exe","appsname"

It does however start working if I put it in the same dir and use relative paths. I think I'll just settle for that

guino · 02-20-2008, 05:46 PM

This is what it should be (as long as VagScope.skin exists in the current skin folder and has an application area defined):

Code:

"LOAD;VagScope.skin;VagScope;C:\Program Files\RoadRunner\VagScopeMod.exe;VagScope"

But I don't think you'll be embedding VAG scope in RR, will you ? you should only need to have it running along with your plugin in the background... all your plugin needs to do is:

1-Read the values from VAG scope (already does it I believe)
2-Whenever a value changes, send it to RR like this:
Sdk.execute("SETVAR;VAG_MPG;12345.67")

As long as you have a label code in the VagScope.skin with this code below it should work:
"=$VAG_MPG$"

Your program should continuously check for updated values in VAG scope and send them to RR. You should add preventions to where if the SDK object errors out (i.e. if RR closes), to either ignore or close your plugin as well (if desired).
