The option "external" in Simulink

2 views (last 30 days)
I have upgraded my MATLAB 2019b to 2020a but the option of "External" was not found in siulink. I want to use Arduino with MATLAB.
I have inserted screenshoot form the options.

You can execute a Simulink Model in external mode, by using the 'Monitor and Tune' options in the 'Hardware' tab in the Simulink Toolstrip. Note that the Hardware tab is only enabled when the target hardware is selected in the 'Hardware Implementation' tab of 'Model configuration settings'.
For more information on choosing the hardware implementation, refer to this community post.
