NMEA code parser

Posted by Koen Delvaux on October 27, 2008 at 5:15am

I wanted to share this NMEA parser code, according to the DIYDrones "should I write a blog post" guide it is best to open a discussion topic about this. You will find the code in attachment.I have no idea if this is anywhere near efficient, but it works. The code should be self-explanatory and is designed to run on a dsPIC. I deliberately avoided unnecessary programming constructs (functions, loops, local scoped variables) to save on memory, processing time and code readability.

Thanks sharing this code. I have used dsPIC for my project. your code is good reference design for me.

Koen,

Excellent---many thanks! Clever going straight to the Uart like that. We don't use PICs so I can't test it. Do you think it would work for AVRs, too?
