I want to perform processor in the loop simulations of a subsystem (controller) in my model on an Arduino Uno board. I successfully generate a PIL block, however I run into the following error message when I start the simulation:

 Data type "double" is not supported for SIL or PIL execution with the current target configuration. This is because the host size (8 bytes) and target size (4 bytes) do not match. To avoid this error, do not use this data type at the component interface.

I've tried using the single precision conversion tool with no effect and also tried surrounding the subsystem with the respective conversion blocks.

Hi,

Could you try adding data conversion block inside the subsystem and delete the folders that contain the generated code before trying again.

Thanks

I solved it by changing the default parameter behavior to Inlined and the parameter structure to NonHierarchical.

Hi Yuan, I tried changing the Default Parameter Behaviour to Inlined and Parameter Structure to NonHierarchical, but am still getting the error. Could you suggest anymore changes that are needed to be done to overcome this problem? Thanks!
