Just found this thread. Looks interesting. I am about to order an OBDII interface so will give it a go later.

In relation to Baud rates, maybe you could just add a new XML tag so this;
<gauges count="5" xpos="0" ypos="0" width="800" height="600" bgcolor="200:200:200" comport="COM6">

looks something like:
<gauges count="5" xpos="0" ypos="0" width="800" height="600" bgcolor="200:200:200" comport="COM6" baud="38400">

I would not have thought that changing the baud rate was too hard, copy it to a global variable and use this variable when you open the comm port. What language are you programming this in?

It wouldn't be too difficult. The main program is written in c# and the odb library in c++. In the next release or two I will be adding that.

Cool, then I will be able to help you then. I know C and some of the newer flavours quite well, it is all the mucking about with the Windows API that I struggle with. I have Visual Studio 2003 here at home. I Gave up on Basic 25 years ago so never got into VB.

I appreciate the offer but the program is not open source.

Good effort! One thing, can you make the com port this is suppose to connect re-configurable in the xml file?

edit: ooops, sorry, missed that it was there. good effort anyways.

Malcolm,

Wow, this looks great!

You tried to work with me a while ago on an OBD-II plug-in for CF...and I totally dropped the ball on it. For that, I apologize. I've been so frustrated with my CarPC that I gave up on getting it to do anything but the basics...and it wouldn't always pull that off. I finally got my major USB issues worked out and it's become usable...what I initially wanted it to be.

This new version looks very nice! I'm going to try to embed it in CF. I should be able to do that as an external application.

I have a few quick questions about the skin.xml.

- The Properties type="dial"...are there other options other than "dial"?

- The "warning" and "danger" values...is that just the color-change (yellow, then red) or does exceeding these values cause an audible warning (I'm not asking because I want audible...I don't)? (EDIT: I just reread your release notes and saw where you talked about this in the v0.2 release...nevermind!)

- The "Rev="0""...any chance that causes the gauge to run in reverse (counter-clockwise)? If it doesn't a) what does it do and b) is there a way to make a gauge run counter-clockwise?

- Is there any way to make one or more of the gauges a half/partial-circle?

malcom2073 · 05-19-2009, 04:07 PM

Hey Habious, I figured life/carpc problems had gotten in the way, I kinda lost interest in CF anyway (Check out my sig, I made my own frontend).
To answer your questions:

- Yes, there are other types, they are still in development.

- Yes, this is just a color change, if audable warning is wanted, that can be a skin option

- Yes, gauges can run in reverse. Try it

- Setting start and end angles to say, 0 and 180, would be a half circle. 90 and 270, 180 and 315, etc would have the same effect. combine with rev=1 for some awesome fun.

On another note, if you're going to be embedding it, I can make an option to remove the titlebar from the window (to make for a cleaner embed)

Habious · 05-19-2009, 06:30 PM

OK, I'm playing...and I'm doing some things wrong, obviously.

When I try to embed it in CF...I get this lovely sight....

The real gauges will flash on the screen for a second, only to be replaced with the above.

When playing with it outside of CF, it displays fine. However, when I try to change "Rev="1"...nothing happens. See example below...

And, I can't seem to figure out how to make a half-circle. All I get is a full circle...with numbers on half the dial.

But...wow...I can see the potential here

malcom2073 · 05-19-2009, 06:38 PM

Haha, oops sorry. Yeah the background doesn't draw half circle, I can add that in on the next release though.

I may not have implemented rev yet... I thought I did. could be wrong. As for the CF issue... how did you embed it? via SetParent? The way it's coded, it draws the gauges on a onPaint event. I'll bet something in how CF embeds windows doesn't allow it to repaint itself perhaps? can you send a WM_PAINT message to the window every half second or something see if that helps? I'll have to download the trial of CF again and check this out.

Habious · 05-19-2009, 09:16 PM

SetParent? WM_PAINT message? Who do you think you're talking to? An intelligent person!?

I honestly don't know what either of those mean!

I just tried to launch it as an "application" bit hitting the big "+" sign on the settings menu.

malcom2073 · 05-19-2009, 09:20 PM

Haha my apologies, I was in programming mode when I answered that. I'll download CF and check it out.

chunkyks · 05-19-2009, 11:31 PM

Heh, heh. WM_PAINT

Silly windows programmers.

malcom2073 · 05-24-2009, 03:11 PM

Odd, I just tried and it loads the program and runs just fine, but it doesn't embed it.

Edit: nevermind it works fine for me, and embeds properly...

joychung · 05-24-2009, 03:42 PM

Hi malcom2073,
I just try your program and it's good! Few question if you don't mind:
1- the MAF pid is 0110 on wikipedia and it's 0111 in your skin.xml. which one is true?
2- the Temp in your program is in F or in Celcius?
3- How can I convert MPG to KMPL (Kilometer Per Liter)?
I'm in Canada so the KM/H and Celcius is familiar with me than MPH and F.

When I exit the program I receive the message "Method not found: 'System.GCNotificationStatus System.GC.WaitForFullGCComplete()'.".

Thanks,
