You don't say which LCD you're using, but the general procedure is as follows:

1. The GPS sends out a string of information every second or so. This string contains lat, long, altitude, etc, etc

2. The Stamp uses its SERIN command (and usually the WAIT modifier) to see the beginning of the string which has a repeating identifying characters. The SERIN modifiers allow the receiving of data as numbers, strings, or individual characters.

3. The Stamp stores the incoming string in available RAM. Note that it may be necessary read the GPS string in two or more sequences if RAM is in short supply. The SERIN SKIP modifier is useful for jumping over data already read in.

4. The Stamp uses SEROUT to display the data on the LCD.

Do a search in the forums or the Parallax main page for GPS and you'll find several examples.

The demo program is designed to read the GPS data and display it on the PC's screen using the DEBUG command. Have you tried it to get familiar with the GPS?

If your LCD was the serial type, you could almost (but not quite) replace each DEBUG with a SEROUT command and send the data to the LCD.

The first thing to do is go to the Parallax site and download the documentation for the parallel LCD which is closest to yours. It will contain the sample code to communicate with the display. Do some experimenting to get comfortable with the display then begin putting the LCD code into the GPS demo code.

As for searching the Forums, some folks say that a search from the Parallax home page gives better results.

Cheers,

bogra, how many posts are you going to start on this same topic? Please stay with one post and if you don't get the answer you want that's what you get. It's not like if you ask the question again you are going to get a different answer. Also if you start a new thread people don't know what has been suggested before and will give you the same answers again wasting everybodys time.
