Configuring BK7231T Chip for PWM on Pin 26 with LED, Relay, and Button Setup

(...) (and relay plays up) stops working when I enable this PWM. I've tried custom scripts with no luck. I just want this LED to be separate completely or make a custom rule like "when the wifi is disconnected toggle the LED the same as channel 1" otherwise completely independent.

Any help would be great!!

Hello User4293554,

It seems like you are trying to accomplish quite a sophisticated task here. It's interesting that the button and relay stop working when you enable the PWM. When they stop working, is it directly because you enable the PWM, or do you change anything else in your setup? Also, can you please elaborate on what you mean by "relay plays up"?

From the scenario you described, I suspect you might be running into a conflict of resources, especially if the PWM frequency is too high. The BK7231T chip is a Wi-Fi SoC, so it has to manage Wi-Fi communications alongside your GPIO tasks. There are limits to what it can handle simultaneously.

Regarding your desire to have the LED behave differently based on the Wi-Fi status, that should be achievable through the BK7231T's SDK. You would typically monitor the Wi-Fi status and adjust the LED's state accordingly in your code.

Can you share the script you have tried? It would help me better understand your setup and try to suggest a solution.
