Hi,
I try to port some AVR code to the Chipkit Uno32. However I'm not really into AVRs, PICs etc. I've browsed this forum a bit, but I don't really get how to convert pinmappings etc. for another chip.
Is there a good tutorial on this, that also explains the basics so I can convert something? Most resources assume that you all already familiar with AVR lowlevel programming and syntax.
I'm not looking for some Noob programming explanation but just some details for average c++/c programmers.

Mmm, chipKIT doesn't seem so alive as the Arduino community itself and the forum is to restrictive to new users. Can't even link to in site URL's (notification says: "Your post looks too spamy for a new user, please remove off-site URLs.") when I link to another question post.
This question is the same as mine: DigitalWriteFast library for Uno32?
Would like to have more information about direct port manipulation, since a lot of great Arduino libraries make use of this.

Anyone? I would like to know this too. Not much fun when I can't figure out how to blink an led. I need to know what to call the pin I'm trying to use.
Thanks

. The errors:
/Applications/Mpide.app/Contents/Resources/Java/hardware/pic32/cores/pic32/pins_arduino.h:84:14: error: 'uint32_t' does not name a type
s_arduino.h:93:14: error: 'uint8_t' does not name a type
These errors are due the not including stdint.h which is a cross platform ctypes like file for defining types based on the number of bits needed (rather than the size of the data bus)
