SPI communication based on interruptions.

Question

Hi,

Dou you know how to implement an SCI communication by interruptions or flags, in PLECS coder (such like that https://www.mathworks.com/matlabcentral/answers/509176-serial-communication-between-two-launchpads). I need to communicate two launchpads using this method because I tried both SPI and CAN BUS, but no one worked.

Answer 1

The link you shared is about "SCI" communication.  There is no component in the TI C2000 TSP to enable SCI communication between processors, although that interface is used to run the PLECS External Mode. Modifying the underlying mechanism behind the SPI/CAN communications is not accessible to the user so the blocks are more intuitive to configure.
