ledcDetachPin code not working with ESP32 3.0.0 core.

[mrdude2478]

What happened?

Unable to compile with ESP32 3.0.0+ core.

To Reproduce Bug

Update esp32 boards from 2.7 to new 3.0+ cores

Expected Behavior

Wanted to compile, but fails on new cores dues to missing ledcDetachPin code in new libraries.

Install Method

Binary from WLED.me

What version of WLED?

Latest release from git release page.

Which microcontroller/board are you seeing the problem on?

ESP32

Relevant log/trace output

Not needed.

Anything else?

I spent about 4 hours trying to figure out why this wouldn't compile, then I found that someone had updated the esp32 board to the newer 3.0 core, after downgrading back to 2.7 core I was able to compile again.

Nobody said WLED is developed for core 3.0.0 (whatever that is).

Please specify what core 3.0.0. means to you.

If you think about using arduino-esp32 v3.0.x - the summary is: it's not possible.

• not supported in platform-espressif32 (see this thread: Support Arduino ESP32 v3.0 based on ESP-IDF v5.1 platformio/platform-espressif32#1225)
• long list of breaking changes for arduino-esp32 (ledc is only one of them) https://docs.espressif.com/projects/arduino-esp32/en/latest/migration_guides/2.x_to_3.0.html
• even longer list of breaking changes in ESP-IDF v5: https://docs.espressif.com/projects/esp-idf/en/v5.1.4/esp32/migration-guides/release-5.x/5.0/index.html and https://docs.espressif.com/projects/esp-idf/en/v5.1.4/esp32/migration-guides/release-5.x/5.1/index.html
• libraries we need must be ported to arduino core v3.0.x, too

As espressif have changed a lot of functions and basicially nothing works as before, there would be a lot of work just to "upgrade" to the latest arduino-esp32. There are no plans in the WLED core team to do this, at least not in 2024.

PS are you trying to build WLED in Arduino-IDE? Please use VSCode with platformIO. https://kno.wled.ge/advanced/compiling-wled/

Building WLED in Arduino-IDE is not supported any more.

Thanks, I've installed visual studio 2022 and Platformio so I'll compiled with that instead, I can compile fine on Arduino though if I disable the a Alexa code and use the 2.7 boards core (I don't use Alexa anyway).
