Hello Akef,
I understand you want to give 8-bit UART input data to a stateflow chart. Refer to the steps below which uses Simulink’s External Inputs feature.
- Open the Stateflow chart and from Stateflow tab choose Chart and then Properties.
- Go to “data” in the left-hand menu and click on “Add” button to add a new external input.
- Give some name in the “Name” field and select “uint8” in Type field and close the properties dialog box.
- In the Simulink model, add a "From Workspace" block to provide the input data, in the properties change the variable_name field to the value you have set earlier in step 3.
- Connect the output of the "From Workspace" block to the Stateflow chart.
- In the Stateflow chart, create a new input event to receive the input data. For example, you could use a transition with a "Message Event" trigger and use the variable to access the input data.
- Once you have defined the input data in the Stateflow chart, you can generate HDL code from the Simulink model. The generated code will include the UART block, and the input data will be connected to the UART block.
