# Arduino 0022 Makefile
4
# written by olikraus@gmail.com
7
# - boards.txt is used to derive parameters
8
# - All intermediate files are put into a separate directory (TMPDIRNAME)
9
# - Simple use: Copy Makefile into the same directory of the .pde file
12
# - requires UNIX environment
13
# - TMPDIRNAME must be subdirectory of the current directory.
16
# all build everything
17
# upload build and upload to arduino
18
# clean remove all temporary files (includes final hex file)
