AVR(Arduino) Platform for Xcode

This is my attempt at seeing if I can get a platform built to allow development of Arduino code within Xcode. It's compiling & linking so far but it's unfinished and doesn't do the hex command yet. Currently it includes a static library for atmega328p that is the core code, I'm not sure if it's best to just build these or figure out a way to build it on demand.

Todo

• Update & include Xcode project template to use proper platform settings
• Properly label object file types elf (probably not necessary, OCD)
• Add phase to handle doing the ihex stuff in target template
• Figure why SDK shows as Unknown OS
• LINKER: Linker is still a mess/hack, compiler feeds flags currently
• Include the standard libraries (and support linking)
• Include AVR toolchain in SDK (maybe in an Installer)
• Have an upload target or phase?
• Support .pde files
• Support dynamic compiling of core library (currently only atmega328p)

Requirements

• Xcode 3 (tested on 3.2, might not work with earlier or Xcode DP)
• 64-bit machine (or build your own gcc toolchain, I'll eventually include both 32 & 64)
• atmega328p until I figure out how best I want to handle the core source

Installation

• Click downloads and download the pkg installer
• Run the installer, installs:
  • AVR.platform to /Developer/Platforms
  • AVRCompilerPlugin.xcplugin to /Developer/Library/Xcode/Plug-ins

Notes

• It's messy, not sure how to do proper linker class yet, methods aren't being called
• Projects using libraries will have to include library sources in their project
• Uploading: Edit the Upload target's build settings to make sure you use the proper settings for your board
• Only has atmega328p support since I statically compiled the core source files
