Processor-in-the-loop Arduino simulation with double data type
显示 更早的评论
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

Hello Gayatri,
I have the same issue with TI C2000 system. I've tried the your method, but it still doesn't work. I've checked my PIL subsystem, there is no double type data and all input and output signals are single and int32. The default data type is also single. Could you please give me some advice regarding that?
Thanks in advance
Yuan

What about Arduino? Are you still facing the same issue? If so, could you please share the model

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!

Hi!
I've the same problem with TI MCU.
The block that you will converter in PIL block has double data type, you need to changue all data type from double to single.
Regards
