Hi, Terry,

I think your code has issue, you have to track down the interrupt source and take action to correct the code.

In order to find out which code line leads to the interrupt triggering, I suggest you set break and get the line, or run the code step by step.

Hope it can help you

I can not tell you which kind of issue will lead to the problem, I suggest you run the application code one by one and check which line leads to the issue.
