I connect the Standard servo read block directly and only to scope. The Arduino board is Uno. So, when I attempted to run the simulation it did not get worked. Showing me some errors like update drivers, reinstall package and so on. So please guide Specifically what settings (or other configurations that may be I forgot to set up) needs to be done. Please tell me in a detail.

Although I have done test connection and all that stuff during the installation of Simulink support package for Arduino hardware. The installation process was successful without any errors or problems. Then why it is showing me such diagnosis error at the time Get on hardware external mode running and simulating…?????

Hi Nishant,

To troubleshoot the errors you encountered when running the simulation of the Standard Servo Read block in Simulink, there are several things you can check:

Check the version of Simulink and the Arduino support package: Make sure you are using the latest version of Simulink and the Arduino support package that is compatible with your Arduino board. You can check this by going to the MATLAB command window and typing "ver". This will display the version of MATLAB, Simulink, and all installed toolboxes.
Check the Arduino support package's installation: Ensure that the Arduino support package is correctly installed and configured in MATLAB. You can do this by typing "matlabshared.supportpkg.getInstalled" in the MATLAB command window. This will display a list of all installed support packages. Check that the Arduino support package is installed and has a green checkmark next to it.
Check the USB connection: Make sure that the USB cable is securely connected to both the Arduino board and the computer. Also, make sure that the correct COM port is selected in the Simulink model.
Check the firmware on the Arduino board: Make sure that the firmware on the Arduino board is up to date and compatible with the version of the Arduino support package you are using. You can update the firmware using the Arduino IDE.
Check the driver installation: Ensure that the Arduino board driver is correctly installed on the computer. This can be checked in the Device Manager on Windows or the System Information utility on Mac.
Check the Simulink model settings: Make sure that the Simulink model is set up correctly. Check that the Standard Servo Read block is connected to the correct pins on the Arduino board and that the sample time is set correctly.

By checking these settings, you should be able to troubleshoot the errors you encountered and get the simulation working.
