I managed to resolve the issue I was having by editing the hardware.cpp of the project from
pinMode(VCC_3V3_PIN, INPUT);
to
#ifdef VCC_3V3_PIN
pinMode(VCC_3V3_PIN, INPUT);
#endif
This has then enabled me to comment out the unused pins in the pins.h
@felmue Thanks again, I have tried this already and it causes issue with the code, which has not been written by me so more difficult to work though currently.
Currently the unused pins that are defined in the code are there as place holders for future development of the code and parts of which have not been written yet
It looks the problem is coming from the board type defined in the environment in platformio. See my comments in the replies above.
Appreciate your help.
@ajb2k3 I understand the message, I just don't understand where it is coming from.
I believe it is related to the board type in platformio I have my environment set up as
platform = espressif32
framework = arduino
board = m5stack-core2
If I change the board type to
platform = espressif32
framework = arduino
board = esp32-s3-devkitc-1
Then I don't get the error messages about the invalid pins, I am reasonably new to all this so just trying to better my understanding.
Is it that the board type m5stack-core2 is it looking for the pins already used on the M5Stack Core2?
@felmue thanks, that has made a difference and given me a working I2C bus and prevents the crashing.
I am still curious to know what is causing the following messages during hardware initialisation, this is now displayed since changing the pins to -1

Hi, I am trying to get a project running on a Core2, I am getting errors related to the GPIO config.
I am using PIO in VSC, my PIO environment is setup as follows.
release (board: m5stack-core2; platform: espressif32; framework: arduino)
These are the GPIO config errors I am getting

This is my pins.h configuration
I have used 100 for pins that are not currently used/required in the project.
