Check the GPIO pins you are using for external signals are being shared by other peripheral functions in your code. Conflicting peripherals can cause one to override the functionality of the GPIO pins.
How to Fix:
Go through your code and ensure that the GPIO pins you are using are not assigned to other peripherals in the pin configuration.
If necessary, reassign the conflicting peripherals to different pins.
6. Check for Pull-up/Pull-down Resistors
Cause: If you're using an input pin and the signal is floating, it might not read correctly, or it could be unstable. This is often the case with buttons or switches.
Solution: Ensure that proper pull-up or pull-down resistors are applied to input pins. If the input pin is floating, it may not detect changes properly.
How to Fix:
Check if a pull-up or pull-down resistor is required for the input GPIO. If it is, add the appropriate resistor to the circuit.
Many microcontrollers, including the CY8C5868AXI-LP035 , have internal pull-up and pull-down resistors that can be enabled in the software configuration.
7. Check for Software Debugging
Cause: Sometimes, software bugs or missing debugging tools can obscure the actual issue.
Solution: Use debugging tools like breakpoints or a serial console to check if your code is running as expected. Monitor the GPIO pin states and verify that your software logic is interacting with the hardware correctly.
How to Fix:
Set breakpoints in the code and use a debugger to step through the execution.
Use printf or serial print statements to output GPIO values and debug your program’s execution.
Conclusion:
If your CY8C5868AXI-LP035 is not responding to GPIO signals, it’s important to methodically check both the hardware and software configurations. By following this guide, you should be able to identify whether the issue is related to pin configuration, power, connections, code, or peripheral conflicts. Debugging with a structured approach will help resolve the issue and restore proper GPIO functionality.
