Description
How to change default HW i2c pins on RP2040 in PlatformIO
from
#define PIN_WIRE0_SDA (4u)
#define PIN_WIRE0_SCL (5u)
to 12 and 13 like in Arduino pins_arduino.h
[env:pico]

Research direction
Start by reviewing the RP2040 Arduino pins_arduino.h definitions and the [env:pico] configuration shown in the issue. Trace how PlatformIO selects the default I2C pins, then verify that SDA and SCL can use pins 12 and 13 for the Pico environment.
