The MCU crashes unexpectedly, resets unexpectedly, or the program runs away. There are several reasons for this.
1. Array out of bounds.
Especially when using pointer operations, if there is an out-of-bounds situation, the consequences will be serious.
2. The power supply is unstable.
You can use an oscilloscope to monitor and check
3. Stack Overflow
Stack is a small space allocated in memory to temporarily store required data during program execution. The types of data stored generally include the following:
1. Local variables and parameters declared in the function
2. Function return value
3. CPU register value at interruption
4. The address returned after the function is executed
Therefore, in the compiler settings, be sure to reserve enough stack space.
