I made a GUI in MATLAb and I want to dump this gui in Microcontroller for which i want to generate Embedded c/c code for gui,I found some video to convert m file , but I dont know how to do for GUI? please help

Code generation is not supportef for GUI functions. How did you develop the GUI application, throught App designer ?

Hi @RJS,
There’s a key limitation for deploying code to microcontroller using Embedded Coder: GUIs built with App Designer or GUIDE cannot be directly converted to C code or deployed to embedded hardware. These GUIs rely on MATLAB’s desktop runtime, which microcontrollers can’t support.
However, you can still deploy the computational logic (e.g., multiplying two numbers) by transitioning your GUI-based application to a Simulink model.
Workaround steps:
  1. Extract the core logic from your GUI (e.g., a × b → result).
  2. Recreate the logic in Simulink using blocks like Inport, Product, and Outport.
  3. Replace GUI elements with hardware-compatible interfaces:
  4. “EditField” → Analog/Digital In (or Inport)
  5. “Button” → GPIO Pin Input
  6. “Display” → Serial Output, LED, or LCD
  7. Use Embedded Coder + Hardware Support Package to generate and deploy code.
Example: Multiplying 2 numbers
  • In App Designer
% Callback for Multiply Button
function MultiplyButtonPushed(app, event)
a = app.InputA.Value;
b = app.InputB.Value;
result = a * b;
app.OutputLabel.Text = num2str(result);
end
This is fine for simulation, but not deployable.
  • Extracting the Logic
function y = myLogic(a, b)
%#codegen
y = a * b;
end
Once extracted, you can:
  1. Import this logic into a MATLAB Function block in Simulink.
  2. Configure the Simulink model for your target hardware.
  3. Generate C/C++ code and deploy it using Embedded Coder.
For more clarifications refer to following documentation links:
  1. Functions not supported for code generation : https://www.mathworks.com/help/coder/ug/function-is-not-supported-for-code-generation.html
  2. Supported hardware in embedded coder: https://www.mathworks.com/help/ecoder/supported-hardware.html
Hope this gives you a clear direction. Once your logic is working in Simulink, hardware deployment is straightforward.
