i have a problem to deal with arduino mega with simulink the problem is the digital block for (read or write) containing numbers from 2 : 19
and the arduino mega have 69 digital I/O
knowing that i modified the serv.pde file as mentioned in the read me file with the package
Can Any one help me ??
thanks for all

I have a problem on selecting pins for PWM that supported by ArduinoMega such as pin 2,4 etc. The warning prompt appeared when I selected it. Its mean the block is not supported for ArduinoMega which contras with the instruction available in model mask.
Please help.

The Mega 2560 has 54 digital I/O pins, from 0 to 53, as specified here: http://arduino.cc/it/Main/ArduinoBoardMega2560 The board groups and labels these pins as "PWM", "Communication", and "Digital" pins. Can you clarify your question or explain what you are doing?

i'm using the arduino board with simulink by using arduino library for simulink when i select any block
it allow to me to choose pine no. from 2: 19 not from 0:54

Hi Mohammed.I understand now. In your model, select Tools > Run on Target Hardware > Options. This action opens Configuration Parameters dialog. Wait a moment for the Run on Target Hardware pane to appear. Change Target hardware setting from Arduino Uno to Arduino Mega 2560. Save and close Configuration Parameters. Now you can enter higher values for the pin numbers. HTH, Rolfe

I don't have any information on how to do this R2011a. The feature I described became available in Simulink R2012a. If you get access to R2012a, enter targetinstaller in the MATLAB Command Window. This action opens the Target Installer and provides instructions for installing support for Arduino.

Hi Rolfe
thank you very much for your help ..
i'm tried to use the support package with matlab 2012a when i choose the the folder that contain the package in target installer dialog an error message appear tell me that the extension i chose does not contain a valid support package
thanks a again for your help
I'm looking into this and will get back to you soon.
Solution #1: In Target Installer, on the "Install or update target" screen, select "Internet (recommended)". Do not select "Folder".

Easy Solution #1: In Target Installer, on the Install or update target screen, select Internet (recommended). Do not select Folder.
Solution #2, (For host computers that do not permit direct downloads from the Internet):
  1. On a private machine, go to http://www.mathworks.com/matlabcentral/fileexchange/35641-simulink-support-package-for-arduino-mega-hardware, click the Download All button.
  2. Transfer the download file, rtt_arduinomega2560_r2012a_v1_0.zip, to a USB memory stick.
  3. Connect the USB stick to the host computer that is running MATLAB.
  4. Determine the drive letter of the USB stick and the folder path of the download file, rtt_arduinomega2560_r2012a_v1_0.zip.
  5. Run Target Installer.
  6. On the "Install or update target" screen, select "Folder" and enter the folder path the download file, rtt_arduinomega2560_r2012a_v1_0.zip
  7. Continue, following the instructions.

Hi Mohammed, Did you try Solution #1 and #2? Are you doing anything to change the zip file or extracting its contents? Which operating system are you using?
I'll make a short video so you can see how I do it.
Jon Zeosky on 31 Aug 2018
Please note that as of September 2018, Solution #2 will no longer be viable, as Simulink Arduino Support will be discontinued for R2012a and R2012b.

the target installed and i checked target options [Run on Target Hardware > Options] the target was Arduino Mega 2560 and the block allow to choose pins only from (2:19) only
Enter arduinolib on the MATLAB command line to open the block library for Arduino. Replace the Digital Read and Digital Write blocks, and any other similar blocks, with the ones from this library.
Can you point me to the original source for your blocks? I'd like to see the readme file instructions regarding the serv.pde file.

thank you very much for your help the problem solved
but i have another problem
when i run the simulation using external mode an error occur (matlab has encountered internal problem needs to close )
