Parsing the .atdf file to get info you can't find in the .h files...

Development Libraries
#1

There's a lot of info that isn't in the .h files that programs include. :frowning:
Stuff like mapping port pins ("PA02") to the functions it might provide, or even chip pin numbers to what port or function they are.

This IS available in ".ATDF" files that Atmel provides. And most probably in the ".SVD" files that are supposedly standard for ARM Cortex-M chips in general. All you have to do is parse them and do some fiddling.

Teaser:

This is coming along nicely. I'm even willing to have other people give it a try...
