Wire1 was not declared in this scope

[troglodisme]

I have been using the below Tasmota platform in order to get my esp32-c6 to work

platform = https://github.com/tasmota/platform-espressif32/releases/download/2024.08.10/platform-espressif32.zip

I wanted to upgrade to pioarduino in order to use BLE but a lot of my existing libraries won't work as Wire1 seems to not be supported when using the pioarduino platformio? I could modify this library but it's literally the same issue on many i2c devices I use.

Can anyone advise?

Maybe this should include something like soc_caps.h ?
This file defines stuff like SOC_HP_I2C_NUM which is wrapped around the declaration of Wire1.

The LovyanGFX library must respect that the ESP32-C series has only one I2C interface (See espressif/arduino-esp32#10408)

Please file an issue to the LovyanGFX library.

Thanks @sivar2311 the library worked completely fine before switching to pioarduino latest platform.

This happens on many Adafruit libraries as well, not just M5GFX.

Did you test on your end? Thank you!

There has been a recent change in the Arduino code which does actually set the correct number of I2C busses for the C6.
So "worked before" was more like "compiled and didn't crash before as I didn't try to access I2C bus 2". :)

Closing since not an pioarduino issue
