Arduino Makefile

Build your Arduino project with a single Makefile instead of using Arduino IDE :

• setup your own project structure
• write a very simple Makefile to build your project
• control all the build process

For now only atmega328p MCU is supported

Prerequisites

• GNU Make (https://www.gnu.org/software/make)
• GNU Tar (https://www.gnu.org/software/tar)

Compatibility

• Linux

Integration

cd project_dir
git submodule add git://github.com/bertrandmartel/arduino-makefile.git
git submodule update --init --recursive

Then create your root Makefile in project_dir like this :

OBJECTS=some_directory/src/main.o some_directory/src2/test2.o
HEADERS=-Isome_directory/header -Isome_directory/header2

export OBJECTS
export HEADERS

.PHONY: all

all:
	$(MAKE) -C arduino-makefile

clean:
	$(MAKE) -C arduino-makefile clean

distclean:
	$(MAKE) -C arduino-makefile distclean

Change OBJECTS and HEADERS according to your requirements :

• OBJECTS contains list of object files .o that match your source
• HEADERS contains list of headers directory

Default usb port is set to /dev/ttyACM0 by default, if you want to override this, add this to your Makefile :

PORT=/dev/<port>
export PORT

You have to provide a main function like this :

#include "Arduino.h"

void setup() {
}

void loop() {
}

int main() {

	init();
	setup();
	while(1)
		loop();
	return 0;
}

Also #include "Arduino.h" is necessary for using Arduino framework

Note that init() function must be called to correctly initialize Arduino module (among other things it will initialize timer registers).

External projects

• Arduino hardware with JSON configuration file
• Arduino Core
• RFduino makefile : a project in the same flavor as this one
