Help GPS read with serin

[Dave]

leinske, I notice 1 thing, I hope the MOB switch is a push button that can only be actuated 1 time or a push button switch with some kind of software flag to disable the EEPROM update after the first write as the actual MOB location will be over written. I would put some kind of flag that you must reset in a different way to maintain the MOB's actual location. Just a thought.......

Hi Dave,
in fact the MOB switch is a 2 positions ON/OFF toggle switch, there is also a pull down resistor on portB.5.

when MOB occures, the switch is set to ON then the program goes to the mob label, return to GPS label, test if switch is on if wel, loops to mob solong the switch is not set to off.

The writing instructions are after the switch test routine, so there are no updates of de EEPROM during the MOB action, I think it's the simplest way to do it ;o)

regards,
Leinske

Dear LEINSKE
Thanks for the source code. I just had a problem with SERIN line now its works well

Actualy I don't need to see on LCD . I catch all relevant fields of $GPRMC and I am sending by SEROUT2 command to PC by serial cable

In your code I can catch only 4 digits of the lan and lat how can I catch all lan lat as is ?
I add lanss and latss variables try to catch all strings I am loosing 0 (zero)

3202.9876 I get 32.02 and 03412.3452 I get 34.12

Thanks

This post should be moved to the GPS thread I feel. It seems a good thread with useful code and it uses a different way of extracting the data fields than my old post in the GPS section.
