How can i use Arduino functions (code) in simulink?

3 views (last 30 days)
Hi everyone,
i would like to use arduino code like tone(pin, freq, duration) in simulink, i.e. to generate a sound with a certrain frequency using a buzzer, standalone on an arduino.
As far as i know, the playtone() function does not work in standalone mode.
How to do it best? S-function? Matlab-Function? ...?
An example simulink model would help me a lot.

That didnt really help much.
A simple example would have helped a lot.
I realized it with a s-function builder and some manual adjustments in the generated .c file ( add extern "C" to each funtion, and rename .c file to .cpp)

Hi. I have the same problem.
If I understand correctly, you created a C file with the tune() function?

There are lot of reference about Arduino Support from MATLAB that enables to use MATLAB to interact with Arduino Board. You may install MATLAB Support Package for Arduino Hardware from Add-on explorer. Also, following link contains many resources around the same.
Similarly, there is Arduino Support from Simulink which you can use by installing Simulink Support Package for Arduino Hardware from Add-on explorer. Here you can develop and simulate the algorithms in Simulink that run standalone on Arduino. For resources to get started you may follow below mentioned link.
