Msp430 MCU Development Record (7) Phenomenon: When debugging a program, I found that the program always crashed. I used online simulation to find the problem. Test: I found that in the simulation environment, the program always points to a fixed address after crashing. This address is the timer interrupt vector address (this can only be seen in the disassembly. For C language programs, you can only see that the program crashed, but you can't see the specific situation). After checking the program again, I found that when the program was initialized and configured, the timer was initialized and configured, and the timer interrupt was turned on because it was required by the subsequent functions. However, because the timer function had not been debugged yet, the timer interrupt service routine was not added. Verification: After adding the timer interrupt service routine, the program executes normally and will no longer run away. Remarks: In the MSP430 microcontroller, if a certain interrupt is enabled, the corresponding interrupt service program must be written. If the interrupt function is not defined for the time being, then create an empty interrupt service function.

It would be better if the OP could provide some pictures to explain.

Because these debugging are all done on the company's products. Sharing experience is fine, but if you add pictures, some of the company's product codes will be shown in the pictures, which is not good

Yes, what you share is indeed classic.
