This project is an effort to program for Arduino hardware using pure C. You will need the Arduino base software (arduino-core Debian package) to be installed.

This package contains:

• a Makefile: self-sufficient (aside Arduino software itself) to compile C++ Arduino projects (including *.ino files) or a pure C Arduino project without libraries or serial access (no /dev/ttyACM0 during execution).
• C core files: porting of a part of the C++ Arduino core for serial communications.
• examples:
• blink: see http://arduino.cc/en/Tutorial/Blink
• bargraph: see http://arduino.cc/en/Tutorial/BarGraph
• digit: controls a single 7 segment display
• shift: same, through a shift register (serial to parallel)

First, decide how you will call the Makefile.

The most convenient way is to add a symbolic link to the Makefile in the project. For example:

arduino.c/
  Makefile
  core/
  bargraph/
    Makefile -> ../Makefile
    ...

Then, you can just change dir to bargraph and run make (the Makefile assumes core/ is in the same directory as the regular file Makefile).

If you cannot use symbolic link or are not sure how to use them, just copy Makefile and core/ in your project directory:

bargraph/
  Makefile
  core/
  ...

Again, you can compile by running just make.

Finally, you can of course use:

make -f ../arduino.c/Makefile

Then, check that the following variables are set to the right values:

Note: $(BASE_PATH) is the directory where the Makefile is located

If you want to compile C++ Arduino project (like the Arduino IDE does), you should add " MODE=cpp" to every call to the make command. If you prefer, you can just uncomment the appropriate line in the Makefile.

The Makefile support the following commands:

• make same as make all
• make all build the .hex file to be sent to the board
• make clean remove the project object files (*.o)
• make cleanobj remove the global object files (obj/)
• make destroy same as make clean and remove the .hex file
• make rebuild same as make destroy all
• make upload upload the .hex file to the board
