Is edge detection (e.g., Rising, falling) in State flow supports code generation using embedded coder?

While generating code Error comes as "Error:Error: File: C:\Program Files\MATLAB\R2023b\rtw\c\tlc\public_api\diagnostics_api.tlc Line: 39 Column: 10 %exit directive: Simulink Coder Fatal: Custom Data Error: Empty DataObject record"

Please support me to resolve this issue.

Thank You

Hi,

Could you share the model so that we can have a better understanding of why this issue occurs?

Hi @Abhijeet Anand,

This is a TLC (target-language compiler) error.

This error might be occuring because of some of the variables might be exceeding the maximum possible size for the variables.

To address this, I recommend reviewing the information provided in the data object usage table. This will help you assess the potential for stack size overflow.

Additionally, a viable workaround for this issue involves adjusting the configuration settings.

Specifically, you may consider setting the "aMaxStackVariableSize" configuration option to "inf" within the TLC options of your configuration set.

>> set_param(modelName,'TLCOptions','-aMaxStackVariableSize=inf') 

You can read more about TLC parameters here: https://www.mathworks.com/help/rtw/ref/maximumstacksizebytes.html

Hope this helps!
