MSPM0 C++ project: service handler considerations

Jan Cumps — Sun, 06 Sep 2026 15:21:17 GMT

You can use C++ for MSPM0 designs. There's one watch-out: if you have your event handlers in a .cpp file, you have to wrap those functions in an extern "C" {} wrapper. The SysConfig mechanism expect that the handlers have a particular name.&nbsp...(read more)
