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

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.

hi can you help me please

???????

hi!

it depends on your question ;)

[sapan agha]

the method with minimum value of error is the best method

[sapan agha]

it is my question

[Michael Goebel]

i'm not sure if this helps

[sapan agha]

ok but if you help me little i will be thankful

[Michael Goebel]

okay, looks like i didnt understand your question.

Could you rephrase your question? Or, if its no connected to the topic, maybe create a new topic with your question.

summarize recalling a matrix in mathlab language programming

[sapan agha]

this my question

[Michael Goebel]

i still dont understand your question, sorry.

Maybe start a new topic, since this doesnt seem to be related to this topic

[sapan agha]

the question say what is recaailng matrix

do you have any idea about recalling matrix

[Michael Goebel]

sorry, i dont. But have you checked this post?

Answer 1

[Michael Goebel]

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?

Hi,

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.
