In the MATLAB support package for arduino, there is no function to be able to write to the DAC (analog) pins! I know that there is a block for it in simulink but i need to write it in matlab code. Has anyone else figured out a way to do this, can i somehow use the simulink block in my code?
Thanks in advance this is super important!

Hi @Logan Hinchcliffe,
As per my understanding, you would like to use MATLAB to write to DAC pin on an Arduino target hardware. A MATLAB function with a similar functionality is not present. But, you can create a simulink model with the "Analog Write" block and simulate it from MATLAB by setting the simulation mode as "Monitor and Tune" using the following command:
set_param(gcs, 'SimulationMode', 'external');
Refer to the following documentation and Community Post for more information:

Hope this helps!
