Hi Tao Cui,
I understand that you are encountering an error with Simulink Coder's external mode stating that Simulink cannot upload data because one of its driving blocks is a top-level inport.
To troubleshoot the error you can use Data Store Read and Data Store Write blocks to pass data between the inport and the scope.
Here's how you can implement the Data Store Memory method:
- Add a Data Store Memory block to your model.
- Add a Data Store Write block connected to the inport that writes to the Data Store Memory.
- Add a Data Store Read block connected to the scope that reads from the Data Store Memory.
Refer to the documentation of Data Store Memory for more information on how to use it within your Simulink model:
Data Store Memory Documentation - https://www.mathworks.com/help/simulink/slref/datastorememory.html
Hope this helps!
