I'm using Arduino Uno and National Instruments DAQ 9215. i'm running the simulink model using "run on board (external)". how do I incorporate the national instruments measurement data to my simulink model?

and i got this error message when I press "build, deploy, and start":

Error:Level-2 MATLAB S-function 'saib' in 'MixedControl_V6/Analog Input' specifies 'SetSimViewingDevice(true)' , which prevents an output port from being created for the S-function.

Hi @Aisyah,

I understand that you seek guidance on incorporating National Instruments DAQ in Simulink Model. Further, you are also encoutering an error as stated in the question. To incorporate NI DAQ into your Simulink model, you will need to install the "NI-DAQmx Support" package from the following link.

For better understanding of the conjunction between NI-DAQ and Simulink, please explore the following examples
