    Your thinking in terms of your screen size...not the scaled screen size. Not everyone has an 800x480 display so any good front end scales the graphics to fit the screen resolution.

    Widescreen Tv's have an aspect ratio of 16:9 (1.78), widescreen computer monitors have an aspect ratio of 16:10 (1.6) and full screen resolution is 4:3 (1.33). Open Mobile aims to bridge the gap between the first two by maintaining around 1.65. To keep things as simple as possible it uses a 1000x500 scale for all dimensions regardless of the screen resolution or OS.

    So long story short, instead of using 800x480 try 980 by 510 (should be 1000 by 500 but I just realized the skin designer was never updated to be exact).

    Nice FE project you got going here....Definately will be keeping track of your progress. Will it have a designated button to toggle back and forth from the FE to the standard OS desktop when needed without having to exit the program? And how about a designated car diagnotics button? Hope it is able to recognize being hooked up to my car's diagnostic port so I can keep updated on my car's diagnosic's on a regular basis without it negatively affecting my car's system(more monitoring capabilities with less technical intergrating for the novice) instead of going to AutoZone to hook up to get diagnostic readings...That would be the bomb!!!

    If the skinner adds it in then yes. The framework supports toggling between window mode/full screen as well as minimizing.

    How about the onboard car diagnostics....Is it feasable?

    Not sure what you mean by feasible?

    OpenMobile currently supports just about everything internally but requires a low level plugin to make the final connection between the framework and the hardware. There is an OMOBD plugin that should be shipping with the next version that will provide support for ELM and similar obd readers but other hardware may need a different plugin.

    As far as displaying that data, the support is all there but afaik there are no skins yet to display the data.

    Might wanna take a look at our wiki for some more info:
    https://sourceforge.net/apps/mediawi...?title=Plugins
    Its technical but should give a better idea of how the FE is organized.

    okay, i will change the resolution of my skin, but which should I skin to right now? 980x510 or 1000x500?

    Whatever fits (pretty sure that 980x510)...its easy to stretch/shrink a tiny bit when i make the correction. You really don't need to worry too much about resolution-more of what you see is what you get. Makes its easier if you want to work with a big skinning window or a small skinning window.

    Been pretty busy with school and such...so things have had to slow down a bit for mid-terms.

    The only big item left on the list till we go beta is to finish the media stuff (which is probably going to be the most difficult item on the projects road map). I'm about 30% done and its probably going to take a solid 2-3 days work to finish so hopefully this weekend.

    I've made good progress on the openOBD stuff, thanks to alot of help from Ws6Vert. Also, spent quite a bit of time assembling the DTC database from a few reliable sources-but its finished. Now comes the linking tables part which is where the real groundbreaking stuff comes into play. That will probably take quite a few more weeks to finish.

    And last but not least, the challenge of true-multiview displays. Some changes need to be made to the framework to support an infinite number of screens (and individual A/V) but its going to require quite a bit of brainstorming to pull off elegantly.

    Planning ahead:
    I have done alot of work previously involving speech recognition and Bluetooth communications. Those are the areas where openMobile will truly start showing off the power of a carPC. I'm starting to plan out these two areas along with the famous navigation question but some issues are already starting to pop up.
    Bluetooth (for windows):
    Most of my code sits just above the kernal layer providing all of the services on top of the bluetooth stack (AVRCP, HFP,HSP,SPP,PBAP,DUN,OBEX,etc.). The base bluetooth stack could be anything but as of now there are really only two good options
    Widcomm/Microsoft and BlueSoleil.
    I would prefer Widcomm since 90% of bluetooth devices could be used by it and it interfaces natively with windows 7 and vista. The problem is that the sound codec for the handsfree profile is part of their undocumented api so unless someone here knows the inner workings of kernal level bluetooth it would cost ~$200 to get the code written for the project.
    BlueSoleil would allow for HFP but their sdk is limited at best and after over a week of discussion with their engineers they not only don't provide any low level access but provide no way for you to add your own profiles.
    Well discuss this more in the coming days and if theres interest (maybe even from other projects) we can see if donations or donations/an mp3car grant could be used.

    Navigation:
    Heres the part where I look like a hypocrite...after commenting on how crazy it would be for a front end to have native navigation, I've been considering it. There are a few managed projects which allow map rendering from common formats, including high speed real time kinda stuff, 3d POI's etc. Since OSM's maps can be exported into just about any format i've begun looking into the possibilities. I'll let you know when I have a better idea....but until then if anyone knows of relevant projects-links would be great.
