Solution:
Check the power supply voltage (typically 5V or 3.3V depending on your setup). Ensure that the microcontroller is correctly grounded and that there are no loose connections.8. Interrupt Conflicts
Cause: Sometimes, multiple interrupts may be configured to use the same resources or vectors, leading to conflicts. This can cause the external interrupt to fail.
How to Check:
Review your code to ensure no two interrupts are conflicting with each other. Check the interrupt vector table to make sure each interrupt has a unique vector.Solution:
If you are using multiple interrupts, ensure they are assigned to different pins or configure them in such a way that they do not conflict.Conclusion
By systematically checking the configuration of pins, registers, global interrupt settings, and the ISR, you can identify and solve most external interrupt failures on the ATMEGA128-16AU. Always verify your wiring, ensure your interrupt service routines are correct, and take necessary precautions for debouncing or noise filtering. By following these steps, you should be able to resolve external interrupt issues and ensure smooth functionality of your microcontroller-based application.
