  This is a support forum for Parallax and their products. While the Parallax GPS and LCD display units are indeed a Parallax product, the level of support possible here for its use with an ATMEGA32 processor is pretty much limited to helping you understand what's described in the existing documentation for the GPS and LCD products. The GPS unit is pretty much a standard asynchronous serial I/O device with logic level signals and whatever library routines Atmel has for asynchronous serial I/O should work. The Parallax serial LCD is similar. It "talks" standard logic level asynchronous serial I/O and the control codes are documented. If you have questions about the Parallax products, please ask, but we can't help you with the coding. You would need to contact Atmel and use their support forums for support for the actual programming of the ATMEGA32.

  I've done some of this with an ATMEGA8 but unfortunately I can't give you the code. I didn't use one of the Parallax GPS's or LCD but just the standard NEMA strings. Your best option is to use the C compiler. If you don't go over the code limit, these people have a very nice C compiler that does a lot of things for you. www.imagecraft.com/ Just note that the way interrupt routines are written in the imagecraft compiler are different to the WinAVR compiler. I believe that the imagecraft compiler also has routines for writing to some lcds.
  
  You may also want to consider a propeller as I think there also objects that do almost what you want to do and it is a lot faster than the ATMega.
