[Q]: Tailoring the Due to Eclipse..

[rbid]

Hello,

Today I got my Arduino Due, so I will be starting to play with it.

Reading through the Arduino site, all the pointers in tailoring Eclipse to the Arduino are for the AVR 8-bit processors and not for ARM, therefore, can someone give a link or a tutorial on how to do it here on the Arduino Due forum?

Thanks in advance and have a nice day!

Hi Ricky,

I have not yet purchased the Arduino Due but I'm also interested in using Eclipse with Arduino Due board in the futur.
I installed Atmel Studio 6.0 (it's free) there is the possibility of creating a project Arduino Due with (Atmel Software Framework : ASF). I know this is not what you want but it is better than the Arduino IDE.
You can download it here : http://www.atmel.com/tools/atmelstudio.aspx

Good luck.

Bye.

I have the Atmel Studio 6.0 which is based on Visual Studio, I just updated it so it I will have the Arduino Due support.
Agree that is more professional than the Arduino IDE because it exposes the ARM processor and you have full control of it.
..... but in another hand, you need to do all by yourself without the Arduino framework.

The reason why I'm looking for Eclipse is that I want my son to get used to a well know IDE used also in several platforms (Embedded, Linux, etc)

Hello Ricky,

It is possible to compile the source code Arduino framework with your program in Atmel Studio.

Today I tried again to tailor it via the AVR plugin or Arduino plugin, both are for AVR environment and not the SAM3

Any one has done this work?.

Atmel Studio 6 is not suitable for me. (I work in mixed platforms, here in a Windows7, and helping my kid under Linux)

Thanks in advance.

Hi Ricky,

This weekend, I wrote a manual for the Board Teensy 3.0 (*) (compatible with Arduino IDE) to compile in Eclipse. The Board Teensy 3.0 is based on an ARM processor like Arduino Due : http://forum.pjrc.com/threads/1474-Anyone-using-Eclipse-for-development

If you want I can try to find a solution for Arduino Due ?
But I could not test the complied binary file because I did not Arduino Due Board.

Does it make you interested ?

Hi Ricky !

I wrote a procedure to use Eclipse with Arduino Due board.
This procedure is written for Winwdows, but you can adapt it to Linux if you want.
But the problem is that I don't now what software to use to uplaod the program in Arduino Due board ...
I can't do test because I don't have Arduino Due board.

Eclipse installation for Arduino Due on Windows

Introduction
This manual is written for Arduino Due IDE.
This manual will allow you install an Eclipse environment to edit and compile your programs but also to communicate with your Arduino Due Board with USB (serial) and a terminal.
This is not a definitive solution, but works very well.

#1. You must first download the following elements:

Hi,

I found the solution to upload your programs with Eclipse.
The Arduino IDE uses Bossa Due flash programming for ARM http://www.shumatech.com/web/products/bossa

How to configure Eclipse:

#8. Aduino Due program loader settings:
-   In Eclipse, on the menu "Run/External Tools/External Tools Configurations…"
-   In the dialog box select on the "Program" item in the tree area, and click on the "New launch configuration" icon.
-   In the "Name" field, type "Arduino Due".
-   In the "Main" tab, in the "Location" field, type the path: "C:\arduino-1.5.1r2\hardware\tools\bossac.exe".
-   In the "Arguments" field, type : "--port=COM3 -U false -e -w -v -b ${project_path}\Release\${project_name}.hex -R"
-   Warning, the port argument value is "COM3" change this value if your board is connected on another Com Port.
-   In the "Common" tab, enable the checkbox "External Tools", and click on the "Apply" button.

#9. Upload program to the Arduino Due board:
-   In Eclipse, select your project, "MyProject".
-   Click on the button "Run Arduino Due" of the tools bar to start Bossa loader. For example: http://ekawas.blogspot.fr/2009/04/google-app-engine-eclipse.html

#10. Connect the terminal to the Arduino Due board:
-   Modify your main.cpp file :

Code: [Select]

#define ARDUINO_MAIN
#include "Arduino.h"

#ifdef USB_SERIAL
usb_serial_class Serial;
#endif

int main(void) {
init();

delay(1);

#if defined(USBCON)
USBDevice.attach();
#endif

Serial.begin(38400);
pinMode(13, OUTPUT);

for (;;) {
digitalWrite(13, HIGH);
Serial.println("Hello World");
delay(50);
digitalWrite(13, LOW);
delay(950);
}
}


-   Compile and upload this program.
-   To open the terminal view, click on the menu "Window/Show View/Other…".
-   In the "Show View" dialog box, in the tree area, select "Terminal/Terminal" and click on the "OK" button.
-   In the Terminal view, click on the "Settings" icon to open the "Terminal Settings" dialog box.
-   Type "Arduino Due" on the "View Title", select "Serial" "Connection Type" select box, select the "Port", select the "Baud Rate" to 38400 and click on the "OK" button.
-   Click on the "Connect" button, the "Hello Word" message appears every second.

Good Luck !
Nassa.

Very well documented Nassa and thanks for the effort.

Nowhere near turnkey enough for this little black duck though, let me know when we just have to do step #10

[Nassarane]

Hi Graynomad,

Thanks for your message.
Yes, I spent a lot of time, it was not easy.
For example how to uplaod a program in the board.
I used the Arduino IDE Due, I have compiled a sample program and I clicked on upload button.
As I do not have Arduino Due board, the Arduino Due IDE displays the following message: "No device found on COM3".
I did a search for text "No device found on" in the folder of the Arduino Due IDE, and I found the file bossac.exe.
I replaced this file with a small program that just prints on the stdout the arguments that are get in parameter.
I clicked on upload button on the Arduino Due IDE, and the parameter are displayed in the Arduino IDE.
In this way I got the list of parameters to use with bossac.exe.

I make an improvement on a tool chain path configuration described on the #2 Step.

If like me, you use different board with different toolchain (AVR, Teensy 3.0, Arduino Due...), you will need to modify the PATH environment variable in Windows depending on the board you are using. It is heavy!
In Eclipse, it is possible to configure environment variable to a workspace and therefore no need to change the Winwdows PATH environment variable :

-   Set the tool chain path, click in "Windows/Preferences".
-   In the tree area in the left of "Preferences" dialog box, select "C C++/Build/Environment".
-   On "Preferences/Environment" clicks on the "select…" button.
-   In the "Select variables" dialog box, enable checkbox of "Path" item, and click on the "OK" button.
-   Back on the "Preferences/Environment" select the "Path" item added, and click on the "Edit…" button.
-   In the "Edit variables" dialog box, add the tool chain path "C:\arduino-1.5.1r2\hardware\tools\g++_arm_none_eabi\bin" without remove the current path values, and click on the "OK" button.
-   In the "Preferences/Environment" click on the "OK" button.

Good luck

Hi Nassa ,

thank you very much for this guide. Maybe, you should create a specific page in a "tutorial" form, in order to be easier to read and follow.
However, I've tried it on my Ubuntu machine and I've encountered some problem:

- I had to install TM-trminal as explained in this guide http://stackoverflow.com/questions/12140381/how-to-open-a-serial-terminal-in-eclipse-juno (via "Install new software" feature) because I couldn't locate the proper "dropin" folder
- in #5 and #7, I think you mean "Same setting for "ARM Sourcery Windows GCC C++ Compiler/Preprocessor" and "ARM Sourcery Windows GCC C++ Compiler/Directories"" (just a typo probably)
- in #8 I had to modify the working directory in ${project_loc}/Release/ and set the bossac parameter parameter as "--port=ttyACM0 -U false -e -w -v -b ${project_name}.hex -R". In particular, pay attention to the ${project_loc} variable, as opposed to ${project_path} which is just relative and didn't work for me
- the hex file is quite large: ~150kB for your "blinking" main.c example, whereas the ArduinoIDE's blink example is just ~10kB when compiled.

The last problem is particularly annoying. Can you give me some more insight?
Thank you very much for your effort!!

[dabbede]

Oh, and by the way, I forgot to mention the most important thing:
for the main.cpp you posted, I was expecting something like a blinking LED on pin13.

However, after uploading the heavy hex, no blinking LED is present! Any idea?!?

[Nassarane]

Hi Dabbede,

For the #5 and #7 steps the correct sentence is :
Same setting for "ARM Sourcery Windows GCC C++ Compiler/Directories" and "ARM Sourcery Windows GCC C Compiler/Directories", and click on "OK"

On the size of the binary, I think there is one or more embedded library are unnecessary. I can verify that.

When I wrote this compilation method for Eclipse, I had no Arduino Due Board. I have not tested.
Today I have an Arduino Due board but the command line Bossac for download only function 1 in 50 on my PC and I do not understand why.
I must first solve this problem.

Thanks for your test.

Nassa.
