**Debug and debugging tools future problems. Add debug prints to track the program’s execution, paying particular attention to interrupt handling and loops.

Disconnect Peripherals:

Test the system without any connected peripherals. Reconnect them one by one to see if a specific peripheral is causing the issue. Inspect the Board for Faulty Connections: Look over the PCB for any bad solder joints or loose connections, especially around the power pins and critical components. Test with a Different ATMEGA128L-8AU: If all else fails, try replacing the microcontroller. This helps determine if the issue is hardware-related.

Conclusion

Freezing issues with the ATMEGA128L-8AU microcontroller can arise from a variety of factors, including power instability, software bugs, and peripheral issues. By methodically checking each of these potential causes, you can pinpoint the issue and apply the appropriate solution. Follow this step-by-step approach, and you should be able to get your system back up and running smoothly in no time.
