Hello,
i have a big problem with Arduino Due, Simulink and the External Mode and need help. The external mode runs good but very slow. 1 millisecond in simulink takes 1 second in real time. How can i fix this problem to run the external mode nearly real time on the screen (scope) and arduino?
thx

Hello Alik,
did you already find a solution? I have exactly the same problem as yours.

Hi Alik, I hope you found the answer. my case is different because I am using Galileo and still having a problem to communicate between the board and the computer. Can you send me the way how you did that with Arduino because they are almost same. Thanks

Hi. I have same problem with Arduino due on Simulink External mode. It was fine with normal mode, but simulation speed slows down with external mode. I think the problem of the speed is beacuse of increased processing burden on external mode as this document said. When I checked task overruns on Arduino with external mode, it always overrun even on very simple code. You can check overrun like this.
