Hi there,
I am doing hardware & simulink synchronization. In order to let both hardware and simulink runing at the same time step, I created a function call subsystem which is triggered by an external function shown below.
The function is from a third party toolbox which I have no idea how it is implemented. But it works fine in my other project.
The error is from the red block which contains only a sine wave generator
I set the sample time type of the function-call to periodic and the sample time to 0.01 which is the same as the same time of the whole model. I want the subsystem generate sine signal only when there is signal coming from Can Receive block. But when I ran this, I got below error
"Function-call block 'can_f_triggered/Function-Call Subsystem1' must be executed periodically when it is activated (enabled) by its function-call initiator because it has a periodic sample time. The function-call initiator did not execute the function-call block on time step '0.0'."
I search online but noting helpful. Can anyone give me a hint how to solve this problem? Thanks in advance.

Hello, did you find a solution for this? I also have the same problem, please help!

As per my understanding your third party is generating periodic signal so please do the following changes on the function call port:
Sample time type: triggered
Also, the "Sample time" should match that of the function-call generator that you are using as trigger. Chose the sample time that you need the MATLAB Function block to run at.
