how to set preference to arduino ide, what file exactly is it?

trouble folowing these instruction,.

what file is the actual IDE? arduino-0022 does not exist. arduino.exe does not work.

(example from instalation instruction copied below)

   a) Specify location of the Arduino IDE

   >> arduino.Prefs.setArduinoPath('c:\Program Files\arduino\arduino-0022')

   b) Specify Arduino board (Duemilanove, Uno, Mega, etc.)

   >> arduino.Prefs.setBoard        % see list of board options
   >> arduino.Prefs.setBoard('uno') % choose a specific board

my arduino installation directory is: c:\arduino-1.0

target dir is c:\arduinotarget

my matlab comand errors:

>> arduino.Prefs.setArduinoPath('c:\arduino-1.0\arduino-0022') ??? Error using ==> Prefs>Prefs.setArduinoPath at 21 The specified folder (c:\arduino-1.0\arduino-0022) does not exist

It looks that error is thrown if "exist('c:\arduino-1.0\arduino-0022','dir')" returns false. Are you sure that there is a folder called 'arduino-0022' under c:\arduino-1.0?

[Dan Sergison]

there is not. i had just copied the instructions. I now have it set to just c:arduino-1.0 which contains arduino.exe

Dan, I would suggest using arduino-023 or arduino-022. Arduino-1.0 has significant changes as compared to the previous versions including reorganizing of some files (structure of the package, the header files etc! boards.txt is used to figure out the board settings and the placement of this file has changed with arduino 1.0)

(For example, Wprogram.h has been renamed to Arduino.h)

your saying to just install arduino 22 and use it with my uno r3 board, because the matlab toolbox is designed specifically to work with v22?

I assume I can keep my arduino 1.0 for use outside matlab/simulink?

[Chirag Gupta]

yes! Even arduino 023 would work fine!

[Dan Sergison]

thank you. it works now with 22 installed.

had trouble with building and example, problem with with a simulink arduino_make_rtw_hook, . will open an appropriate thread.

thanks again ALL of you for helping!

Answer 2

[Chirag Gupta]

The release before arduino-1.0 was arduino-023 (and before that was arduino-022)

Just set the arduino root folder (under which arduino.exe is present)

[Dan Sergison]

I did that, but then I cant figure out ow to set the board preferences. I figured it must be because I had specified the wrong path. I did not know that arduino.exe was the "IDE file" it was looking for, thank you. still, I can't proceede.

my path is set to the directory with arduino.exe

>> arduino.Prefs.setArduinoPath('c:\arduino-1.0')

per instruction part b I tried to list the available boards:

>> arduino.Prefs.setBoard

??? Reference to non-existent element of a cell array.

Error in ==> Prefs>Prefs.parseBoardsFile at 227

lhs = parsedLines{i}{1}{1}; % can be of the form xx.yy.zz

Error in ==> Prefs>Prefs.setBoard at 66

boards = arduino.Prefs.parseBoardsFile(boardsFile);

and tried to set to UNO

>> arduino.Prefs.setBoard('uno')

??? Reference to non-existent element of a cell array.

Error in ==> Prefs>Prefs.parseBoardsFile at 227

lhs = parsedLines{i}{1}{1}; % can be of the form xx.yy.zz

Error in ==> Prefs>Prefs.setBoard at 66

boards = arduino.Prefs.parseBoardsFile(boardsFile);
