MATLAB: Does the generated ASAP2 file not show the parameter under the CHARACTERISTIC section

a2lasap2characteristicclassEmbedded Codersimulink coderstorage

When I generate code, and enable the ASAP2 interface, the generated A2L-file does not show the parameters under CHARACTERISTIC, even though I can see them in the generated C code. Why does this happen, and how can it be resolved?

Best Answer

A data item is not represented in the ASAP2 file if any of the following conditions exist:
  • You apply one of the storage classes Auto, FileScope, or SimulinkGlobal.
  • You apply a custom storage class that causes the code generator to generate a macro or non-addressable variable.
So as long as the custom storage class does not generate a macro, or a non-addressable variable, it will show up in the A2L file. With respect to built-in storage classes, this can be achieved by selecting 'ExportedGlobal':
>> myParameter.CoderInfo.StorageClass = 'ExportedGlobal';
Once the above command is executed for the parameters and signals, the CHARACTERISTIC and the MEASUREMENT sections show up correctly in the ASAP2 file.
