Following the initial concerns, I have conducted a more detailed isolated test specifically for GPIO4, aiming to eliminate any external factors that might be affecting its performance. Here are the steps and results from this test:
Script Execution:
I prepared a Python script dedicated to testing GPIO4 functionalities. This script includes steps for setting up the GPIO, changing its state, and cleaning up:The script was run on the CM4, and I carefully monitored the process and outputs.
Test Results:
The script executed successfully without any errors. Each step, from disabling warnings to cleaning up the GPIO, proceeded as expected. The GPIO pin was successfully set to HIGH, and the program paused for the intended duration of 2 seconds before cleanup.
Console output from the test:
Disabling warnings...
Setting GPIO mode...
Setting up GPIO pin as output...
Setting GPIO pin to HIGH...
Sleeping for 2 seconds...
Cleaning up...
Done.
Conclusion from Isolated Testing:
This isolated testing suggests that GPIO4, at least in a standalone scenario outside of the larger application context, is functioning as expected on the CM4. This outcome has helped narrow down the issue, indicating that the problem might not be with the GPIO setup or the CM4 hardware itself.
Given these results, I'm inclined to think the issue might be related to how the GPIO interacts within the larger application, especially consid
I would greatly appreciate any insights or suggestions on how to proceed from here, especially from anyone who has dealt with similar GPIO-related challenges in complex applications.
Thank you again for your support and guidance.
