I need an Arduino free environment myself, for both PicoSDK (already possible) and ESP32. Just pointing out to anyone reading that that is will be enabled by a flag, we are not touching the Arduino flow in any way whatsoever.

A first step toward this has been achieved recently, if you look at https://github.com/TcMenu/tcLibraryDev/blob/main/cmakeEsp32/generateCmake.py it can generate CMake files into the components directory of an ESP32 IDF project. It presently has been tested with IDF 5.5 with the Arduino component still referenced. Once I've cleaned things up, I'll be pushing my working example into that directory.

It is not much work to move over to IDF completely and I'll test that at some point soon. I list out below what's already done, and what I'd need to do:

• SimpleCollections should compile in any C++ compliant environment. Does so for PicoSDK already.
• TaskManagerIO - should compile in any C++ compliant environment. Does so for PicoSDK already.
• IoAbstraction - has a hidden experimental flag (been there for a while) that handles Analog and Digital IO direct IOA_USE_ESP32_EXTRAS.
• tcMenu - doesn't use Arduino directly, only through plugins. There are display plugins for at least LiquidCrystal and OLED without Arduino. It should be easy to add a TFT driver if a component is already available.
• tcUnicodeHelper - should compile in any C++ compliant environment. Does so for PicoSDK already.

I have proven this with PicoSDK and StmCube. When mbed was deco'ed I had to come up with a way to get my additional examples working elsewhere. With ST themselves supporting CMake now, and the support for it is exceptionally well done (similar to PicoSDK) I implemented it. IDF is already half implemented, given I'm in this mode already, this will be done next, and we'll then support STM32Cube, ESP32-IDF and PicoSDK along with Arduino.
