C Union data type in Matlab/Simulink

34 views (last 30 days)
Hi all,
I am trying to port embedded hardware driver files written in C to Simulink using C Caller.
I am able to port it except the Union datatype. Matlab does not recognise this data type.
Has anyone been able to solve this?
The final aim is to use embedded coder to generate C code to run the hardware.

You are correct that Simulink does not support unions. If you plan to use only one of the union-ed fields in your Simulink model, you can temporarily replace the union-ed field with the actual field you will use in Simulink. After genratig code, you can switch back to the original header file that contains the union.
