| # Arduino 0022 Makefile 
 | |
| # Uno with DOGS102 Shield
 | |
| #
 | |
| # written by olikraus@gmail.com
 | |
| #
 | |
| # Features:
 | |
| #   - boards.txt is used to derive parameters
 | |
| #   - All intermediate files are put into a separate directory (TMPDIRNAME)
 | |
| #   - Simple use: Copy Makefile into the same directory of the .pde file
 | |
| #
 | |
| # Limitations:
 | |
| #   - requires UNIX environment
 | |
| #   - TMPDIRNAME must be subdirectory of the current directory.
 | |
| #
 | |
| # Targets
 | |
| # 	all		build everything
 | |
| #	upload	build and upload to arduino
 | |
| #	clean	remove all temporary files (includes final hex file)
 | |
| #
 | |
| # History
 | |
| #	001	28 Apr 2010	first  release
 | |
| #	002  05 Oct 2010	added 'uno'
