| # 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 .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) | ||
| # | ||
