Thread: GPS software i've written...

why is it tellen me 1000 kph when i'm only driving 10 kph ?

I'll give it a shot when my GPS receiver gets installed

That'd be telling... VB6, dont see the point in overcomplicating a sinple task like this using languages like c++, it isnt needed,

Not entirely sure, it works fine for me when i use KPH, and it also worked fine for our Canadian friend ^^ up there in KPH.. perhaps you've got the baud rate set wrong or something? honestly cant say for sure... what GPS reciever do you have ?

Can you gine me the source please ? I'm thinking of making a program gps based that gives an car maintance program with a range function also

is it in vb ?

I'd rahter not give out the source, it's ni my portfolio and i hope it will help me get a career sometime in the near future, i'll be perfectly willing to give you a hand with re-writing something similar yourself, and am willing to send you code snippets but like i say, want to keep it closed source (for now).. if you use msn you can add me ( ripz [at] binary-pulse.co.uk ), and yeah, its VB

thescrew.. really its not hard.. just open up hyperterminal and open the com port where the gps device is.. you'll watch it spew a whole lot of info.
Google for NMEA parsing.. you'll find all you need to understand what its saying.
Really. Its the easiest thing to parse. I wrote my parser in about an hour.
Great article on codeproject written in vb.net . All the source is there too. I modeled mine after that one.
good luck.

As knubile says, the GPS is the easy bit.. on my software the hardest bit is the graph drawing.. and another bit which you lot havent seen because its not in that version (it can draw a map of a circuit and do lap timing - in theory, i've not finished coding it).. NMEA is a simple protocol.. a series of comma separated values, that's all
