Ezt, a kis szösszenetet magamnak fordítottam le (szabad fordításban ebből a forrásból), hogy meglegyen a wikim-ben későbbi felhasználás céljából. Sokat kutakodtam mire ráleltem, de megérte mert működik.
Tesztalanyunk egy Win7 64bit PC, + Arduino Duemilanove lap. Mással nem teszteltem! Kéretik figyelembe venni! Ha valaki mégis mással is kipróbálná, és nem megy, de rájön miért nem, kérem, ossza meg és frissítem a cikket.

The ArduinoCore library will contain all the basic functionalities to deal with the Arduino board, this library can be seen as the standard c library equivalent for Arduino. If you write some code for Arduino in the Arduino IDE, this library is silently linked to your code, but if you plan to use Eclipse you have to manually link the library to each of our projects before deploying them on the Arduino board.
Here are the steps to create the ArduinoCore library (which is just the name I gave it):
Ha minden rendben ment, akkor le tudjuk fordítani az ArduinoCore könyvtárat (projektet). Próbáljuk is meg: jobb klikk az ArduinoCore projekten -> Build Project
Let’s now create a test project to check that everything’s fine.
Remember that these steps must be done with every new project that you create.
Right click on the “ArduinoCore” project, go to “Properties” and then “C/C++ Build” and in both “AVR Compiler” and “AVR C++ Compiler” add the same include paths that were added in the ArduinoCore library project plus the include path for the test project itself which is not added by default and can be added with this magic string: “${workspace_loc:/NULL}” which simply expands to your workspace directory followed by the test project directory.
NULL --cref -s -Os NULLNULLNULL NULL -lm NULL
In the “Libraries” box add the ArduinoCore library by clicking on the “Add” button on the top right corner of the box and simply type “ArduinoCore”, this instructs the linker to link against “libArduinoCore.a” when linking the final executable.
In the project properties window, click on “Project references” in the left menu and check“ArduinoCore”, so the library will be automatically built (and re-built if needed) when building the test project.
In the test project create a new main.cpp file and paste the following code into it.
This is the classic Blink code sample that blinks the led linked on pin 13 of the Arduino board once every second:
| #include <Arduino.h>
int ledPin = 13; // LED connected to digital pin 13
// The setup() method runs once, when the sketch starts void setup() { // initialize the digital pin as an output: pinMode(ledPin, OUTPUT); }
// the loop() method runs over and over again, // as long as the Arduino has power
void loop() { digitalWrite(ledPin, HIGH); // set the LED on delay(1000); // wait for a second digitalWrite(ledPin, LOW); // set the LED off delay(1000); // wait for a second }
int main(void) {
init(); setup();
while(true) { loop(); } } |
You’ll notice that there are some difference between this code and the usual code that you write for Arduino, the next post will focus on these differences, for now just take it as it comes. No questions. Or this post will never end.
Deploy on the Arduino board
After compiling and linking the binary a tool named AVRDude will deploy it on the Arduino board.
AVRDude must be configured to work with Arduino.
What we are going to do now is stealing the AVRDude configuration from the Arduino SDK.
From Eclipse go to “Window” then “Preferences” and select the “AVR” section on the left, then select “AVRDude”.
Check “Use custom configuration file for AVRDude” and set “AVRDude config file” to the one provided with the Arduino SDK: it can be found under<arduino_base_path>\hardware\tools\avr\etc\avrdude.conf.
Click “Apply” and then “OK”.
From Eclipse select the test project and open the project properties once more (right click->“Properties”).
Select the “AVR” section and the click on “AVRDude”
You now have to create a new programmer configuration for your board, this must be done only once.
Click “New”, in the window that appears insert these data:
And set “Override default port” to the COM port that you use to work with the Arduino board. If you do not know what this value is, plug your Arduino board in and start the Default IDE, the COM port is showed at the bottom of the IDE window, my Arduino IDE says:
Arduino Duemilanove w/ ATMega328 on COM10
My COM port is COM10 so my “Override default port” field is set to:
//./COM10
Don’t ask me what the “//./” prefix means, I don’t know.
Click “OK”
Back in the “AVRDude” window select the “Advanced” tab.
Check “Disable Device signature check” and click “OK”.
First deploy
It’s time. Plug your Arduino board in.
Select the test project and build it, then right click on it and select “AVR” and then “Upload project to target device”, the deploy will start and if everything’s fine you should have your program running on the Arduino board after a few seconds. Look at the led at PIN 13 and it should be blinking. Mine blinks.
That’s all, hope this guide is useful.
Again, let me know any problem you had so I can update the tutorial with your info.
Hava fun! 🙂
