Hello MathWorks team,
I have a Simulink model named experiment_demo.slx that includes a MATLAB Function block with the following code:
function adjusted_setpoint = fcn(setpoint, cfg)
adjusted_setpoint = setpoint * cfg.gain * cfg.offset;
setpoint is provided via an Inport.
cfg is a tunable parameter defined as a Simulink.Parameter with a Bus type (ModelConfigBus) and configured via the Model Explorer.
Model configuration:
Solver: Fixed-step
Code Generation:
System target file: ert.tlc
Code interface packaging: Reusable function
Code is generated using Embedded Coder. In the generated code:
The ModelConfigBus struct is defined in experiment_demo_types.h as:
typedef struct {
real_T gain;
real_T offset;
} ModelConfigBus;
My goal is to pass the cfg parameter directly into the generated experiment_demo_step() function, so that it can be configured from an external source (e.g., another module or application). Ideally, I would like the struct to be declared in experiment_demo.h and used as an input argument in experiment_demo.c.
Questions:
What is the recommended way to expose a tunable struct parameter like cfg as an input to the step() function in the generated code?
Is there a configuration or customization (e.g., via code interface settings or TLC customization) that allows this struct to be passed explicitly to the step function?
Would moving the struct definition from experiment_demo_types.h to experiment_demo.h be supported or recommended for this use case?
Thank you!Hello MathWorks team,
