[fpc-other] [fpc-pascal] Access GPIO pins on RPi2 without root?

[Travis Siegel]

This is good to know.  I've not tried using fpc to read io pins on the pi 
yet, but it's certainly nice to have the option.  I will keep this post 
for when the inevidable occurs, and I decide to use fpc for a project on 
my pi.  Honestly, I didn't even realize it would be possible to read the 
io pins from fpc, so I didn't event hink about trying it.  This opens some 
nice possibilities.  Thanks for the post.
