External mode simulation is not supported for the 'arduino uno' hardware. however, you can deploy the model on this hardware. from the model window, click the 'deploy to hardware' button

i got a problem with arduino uno when connected in simulink and this (External mode simulation is not supported for the 'arduino uno' hardware. however, you can deploy the model on this hardware. from the model window, click the 'deploy to hardware' button).

Hi @panda xl,

I see that you want to execute External mode simulation on Arduino Uno, but it is not supported in the MATLAB/Simulink version that you are using.

You may consider upgrading your MATLAB version to R2016b or later because External mode for Uno was added in R2016b.

Refer to the following MATLAB Answer thread for more details:

Here are some documentation links for more information on tuning and monitoring models on Arduino hardware with Simulink:

Hope this helps!
