I have to debug a signal from a GPS readed by a raspberry pi 4. From the gps i obtain the time in hh:mm:ss:ms and i save it on a file. I want also to save the system clock of the raspberry (NOT the simulations time), to compare the delay. Currently i am deploing a simulink script with the raspberry toolbox. How is it possible? Thanks to all.

You need to include profile_timer.h from MATLAB\R2023a\toolbox\target\shared\armcortexabase\include\profile_timer.c. This has a function called profileReadTimer() which is defined in MATLAB\R2023a\toolbox\target\shared\armcortexabase\src\profile_timer.c. This function can be called to access the local time of the Pi.

Thanks for the reply. Excuse my ignorance, but I have another question for you. What do I call this function? With a C function block, right? Thank you very much.

Yes, presumably, although that depends on your use-case. You can also manually insert the function call after C/C++ code generation of your Simulink block.
