How to properly handle objects within level-2 Simulink S-Functions
3 views (last 30 days)
I'm attempting to use a level-2 S function to handle serial read/write to and from a device.
I need some help with two things:
- How do I handle dialogue parameter inputs? I'd like to input the specified com port.
- How can I create a serialport object that persists throughout an entire simulation? I'd like to avoid opening and closing the commport each iteration.

while this does not directly answer your question, have you tried to use the Packet Input/Output or Stream Input/Output blocks with the Serial Port driver? These blocks from the Simulink Desktop Real-Time product library should be able to handle reading/writing serial port devices out of the box, with no programming necessary.
