[3]Anyone modify the Parallax GPS code? Any warnings/hints?[/3]

[3]I want it to just send: Valid signal code, Latitude and Longitude (from the GPRMC string). I don't even need E/W, N/S as the app. is land based on this continent.<SPAN style="mso-spacerun: yes">  I wanted Date and Time also (for logging), but I'm worried about data lengths and date/time stamp would be candy.[/3]

[3]Am I wasting my time because the data comes around fast enough as it is?<SPAN style="mso-spacerun: yes">  AND the data is only coming out of the GPS side once a second. I saw someone's name in there. Any thoughts? (besides: "You should get back to your project and stop messing with the stuff that already works")[/3]

[3]I'm guessing I can't up the baud rate due to the oscillator?[/3]

[3] <o:p></o:p>[/3]

[3]My idea is this: My app can start listening, sync on the Valid Code ("A"=valid or "V"=invalid)*, get the numbers and get back to work. I think I'm going to put the date/time stamp on the end of the output string for future use.[/3]

[3] <o:p></o:p>[/3]

[3]The GPS unit would continuously send my output string, updated or not. If a program poles for data too fast, there will be a lot of old data duped as new data from the GPS radio side has not been received yet. I will add code if the radio fails/times out, it will catch it.[/3]

[3]Anyone solder pins to the GPS unit to attach the Key?[/3]

[3] <o:p></o:p>[/3]

[3]Every time I start to do this, I hear a tiny voice in my head say:[/3]

[3] <o:p></o:p>[/3]

[3]"STOP., put the soldering iron DOWN., raise your hands and back slowly away from the bench."[/3]

[3] <o:p></o:p>[/3]

[3]TIA, Chris[/3]

[3]* V=invalid, aren't we supposed to use correct mnemonics? or is this GPS thing a Gov't project?[/3]
