TI source file interrupt vector file for 28335 [Copy link]

There are two interrupt vector source files for 28335 provided by TI, DSP2833x_DefaultIsr.c and DSP2833x_SWPrioritizedDefaultIsr.c. When I included these two files into the project, the prompt symbol was redefined in these two files. I kept DSP2833x_SWPrioritizedDefaultIsr.c, which caused DSP2833x_PieVect.c to report that the symbol was not defined. Only keeping DSP2833x_DefaultIsr.c can compile. Please explain these two files, because I see that they both define interrupt programs and I can't see the difference.

I looked at it myself, but I don't know if I understand it correctly. These two source files are files that define interrupt routines, and their definitions overlap. The definition of DSP2833x_SWPrioritizedDefaultIsr.c is more complicated, with definitions enabled and editable interrupt priorities. For example, TINT0 is enabled to the highest priority of the group of PIEs, while DSP2833x_DefaultIsr.c is simply defined according to the default interrupt priority of the device. Now comment out one of the interrupt functions that are repeatedly defined in the two files, and it can be compiled normally.
