Not working using new Arduino Nano ESP32 development board

[nestorcereno]

Not working using new Arduino Nano ESP32 development board (Arduino IDE).
Arduino Nano ESP32 development board is using ESP32-S3 MCU.

When compiling using ESP32-S3 board, there was no error but when using new Arduino Nano ESP32 board, there were errors.

Can somebody please update the library? Thank you in advance for your help.

using new Arduino Nano ESP32 board, there were errors.

What were the errors?

Thank you!

Here are the compilation results using ESP32 S3 Dev Module and Arduino nano ESP32 as board. I used the example code Adafruit MCP23017 Arduino Library (mcp23xxx)blink).

ESP32 S3 Dev Module as board: (compilation OK)
Sketch uses 287321 bytes (21%) of program storage space. Maximum is 1310720 bytes.
Global variables use 20304 bytes (6%) of dynamic memory, leaving 307376 bytes for local variables. Maximum is 327680 bytes.

I tried the IDE Tools option "Pin numbering: By GPIO number (legacy)" and the compilation was OK!

I will try if the example code will work when i upload it to the new Arduino Nano ESP32 board.

Thank you!

[caternuson]

Thanks for the compilation output. Was able to recreate this locally.

The issue is with the ESP32 Board Support Package. There's an open issue about this here:
espressif/arduino-esp32#9150

I tried the suggested "easy out" option:

By forcing users to use the standard ESP32 pin naming (by choosing "Tools" -> "Pin Numbering" -> "By GPIO number (legacy)" in the Arduino IDE), no macros will be defined and your library will work out-of-the-box with no source changes.

and that got rid of the compilation errors, however, did not test any further (just a compilation check).

Try that and see if it both compiles and runs as expected once the sketch is uploaded.

Hey there, I do not have such an option in platform.io. Do you know any other solutions for this?
