    well today was the day my gps unit came in.
    it took me about 30min to do everything from opening the box to opening the gps to find the pins in needed. to wireing the cable and to testing, it went quite easy, i used a 1k resister.







    im very intrested to try the maping project

    Noway, there are a few threads ps2dev.org explaining why it would not work, at least with "regular" gps devices

    seesoe, can you verify the speed that you read from the gps236?

    Mine seems to always get 20-30% lower value, then the actual, especially when driving fast...
    I wonder if this is just my unit or all of them.. or perhaps something in the code...

    yes i can i also found that when i was going about 56 the psp would read out 45 it was always around this number of differ when going fast. im starting to think its with the setup maybe, cuz i also used the gps reading program that has the green background to it and i found it was about the same thing. i might charge the battery of the gps unit and hook it up to my laptop and re do the speed testing.

    maybe we can narrow it down with the help of f n noob's speed read out from both gps programs with the use of his gps 360

    I got it figured out.. I did not read the NMEA spec carefully.. the speed is posted in KNOTTS.. I already made adjustments to the code to make the speedfix configurable so you can convert it to MPH or KPH

    I fixed that and tweaked the graphics a bit...
    Still may need someone to work on better graphics: fonts icons, etc...
