how to update one signal of bus from another signal of same bus in simulink and get the resultant c code

I have a bus with structure as

typedef struct

{

double InputVar;

double OutputVar;

}MyStructDef;

and want to achieve c code as below:

MyStruct.OutputVar = 3.14 * MyStruct.InputVar;

where

MyStruct is structure variable of type MyStructDef;

Hello Amit,

To achieve the desired C code output in Simulink, consider using a combination of a Gain block to perform the multiplication and a Bus Assignment block to update the bus signal. Set up your bus structure in the MATLAB workspace and configure your model to use this bus.

Then, use Simulink Coder to generate the C code, ensuring that the target file is set to ert.tlc for efficient code generation. This approach will help you map the Simulink model logic to the desired C code structure.

Please refer to the following documentations for further implementation details:

• Bus Assignment: https://www.mathworks.com/help/simulink/slref/busassignment.html

I hope it resolves your query!
