Can you make it work with other boards? Just select "ESP32 Dev Module" for example.

Same Error ....

Try to delete the EloquentTinyML-master folder from the Arduino\libraries folder and install the library via Arduino IDE library manager.

I have a similar issue, I'm trying to compile it for "ESP32 Dev Module", I tried uncommenting the min/max but the error is the following:

Error compiling for board ESP32 Dev Module.

I'm just trying to upload the example files for the SineExample.ino, hope you can help as I already followed your recommendations here in the thread and doesn't work yet

[eloquentarduino]

I can confirm it worked on "ESP32 Dev Module" since I used it in my own development. I will take time to look at those files that gives you error. Can you please confirm which core are you using for the ESP32?

[arnaudonate]

Sure, thanks for the quick reply!

I'm usign the ESP32-WROOM-32 (On an AZDelivery dev board), I've had some issues in the past with the BUILTIN_LED, I usually need to write pin 1 directly otherwise it won't work. Not sure if that can be related at all, hope it can bring some light into the matter.

Thank you for your help!

[eloquentarduino]

I updated the library. Please install from Github since I didn't published on the Arduino Library Manager yet since I made a major update and need to test yet.

[arnaudonate]

Thank you so much! I will tets it now :) This is very helpful!

[embedragx]

I will try it soon.

And thnx for the effort 👍
