What version of the ESP32 board support are you using? With the latest released version, I cannot replicate the error above. You can check the Board Manager for the version.

What board are you selecting? Check the Tools Board menu.

Thanks for the link, I am applying that correction now.

Hi,

I'm using 3.0.0-alpha3 (as I need the support for the ESP32-C3). In the Board manager select the ESP32C3 Dev Module.

Cheers, Henk

I am in the middle of some other work and can't switch to v3.0.0-alpha3 at the moment. I wish they would make a release with it marked as beta and not default so that it's easy to switch to it and back.

If you could pick up my master and give it a try and let me know if there is anything else, that would help.

[Henk Holdijk]

Will give your master a try this evening.

[Henk Holdijk]

Sorry, but only a slightly changed error.

[Michael Miller]

thanks, I will take a closer look in a week or so when I clear some other things off my table.

[Michael Miller]

They have made major changes to both RMT and I2S interfaces of which this library relies on both. It will require significant rewriting and refactoring to remove deprecation warnings.
