I have several models from which I generate C code using the Embedded Coder toolbox.
In these models, I would like to use a neseted structure variable to share information.
'Fault_value', single(0),...
As this structure is shared across multiple models, the definition should be done in a separete file.
First I create a simulink bus for each strcuture:
Simulink.Bus.createObject(Faults);
clear model1 model2 f1 f2 slBus1_f1 slBus2_f2 slBus3
Then I assign the bus type to each element:
faults_t.Elements(1).DataType = 'Bus: model1_t';
faults_t.Elements(2).DataType = 'Bus: model1_t';
model1_t.Elements(1).DataType = 'Bus: st1_t';
faults_t.Elements(2).DataType = 'Bus: st1_t';
faults_t.Elements(1).DataType = 'Bus: st1_t';
model2_t.Elements(2).DataType = 'Bus: st1_t';
In order for the type to be defined outside the models headers I define each bus DataScope as Exported.
faults_t.DataScope = 'Exported';
model1_t.DataScope = 'Exported';
model2_t.DataScope = 'Exported';
st1_t.DataScope = 'Exported';
Finally I create a Simulink.Parameter of Faults and set the DataType to 'faults_t'
Faults = Simulink.Parameter(Faults);
Faults.CoderInfo.StorageClass = 'ImportedExternPointer';
Faults.DataType = 'Bus: faults_t';
One I have done this I set constant blocks inside the models using this names
- Faults.model1.f1
- Faults.model2.f2
The expected output would be:
- The code is generated correctly
- The models use a pointer to Faults variable
- The definition of each structure is generated in a separated file. (test_model.c, test_model.h, faults_t.h, st1_t.h, ...)
