# Arduino-1.0 Makefile
|
||||
#
|
||||
# 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 .ino 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)

# Arduino-1.0 Makefile
|
||||
#
|
||||
# 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 .ino 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)
