platform-espressif32

Boards like the ESP32-C6, almost 5 years old, are not supported in PlatformIO with Arduino libraries, because they refuse to update the Arduino core in some kind of stand-off with Espressif. This has been going on for years. There is a fork [1] that offers support but none of it makes back upstream. As a hobbyist I've given up on PIO and moved to a barebones arduino-cli setup instead. Much lighter and less painful. [1] https://github.com/pioarduino/platform-espressif32

For those using PlatformIO, the folks at pioarduino[0] are doing a great job keeping up with Arduino Core 3.x support. ``` # platformio.ini platform = https://github.com/pioarduino/platform-espressif32.git#55.03.37 framework = arduino ``` [0]: https://github.com/pioarduino/platform-espressif32

There is also https://github.com/pioarduino/platform-espressif32 which allows one to use Arduino > 3.2 and IDF > 5.4. If you use PlatformIO put this into your platformio.ini [espressif32] ; PLATFORM platform = espressif32 board_build.embed_txtfiles = folder/file.ext ; embed null-terminated file(s) Also have a look at https://docs.platformio.org/en/latest/platforms/espressif32.....
