PICO_DEFAULT_I2C_INSTANCE undefined

/home/pi/Code/pico/hm01b0-library-for-pico/examples/serial_terminal/main.c:12:22: error: 'PICO_DEFAULT_I2C_INSTANCE' undeclared here (not in a function)

This issue exists for both serial_terminal example and usb_camera example.

The issue appears to be fixed by replacing PICO_DEFAULT_I2C_INSTANCE with PICO_DEFAULT_I2C. However, I have as yet been unable to get anything other than a blank screen so far, so I'm not yet certain whether this is a safe fix.

Hi @ccason1,

Please try using .i2c = PICO_DEFAULT_I2C_INSTANCE(), instead of .i2c = PICO_DEFAULT_I2C_INSTANCE,.

I believe this is one of the breaking changes introduced with the 2.0.0 of the pico-sdk.

Thank you! The serial_terminal example now works. I'm still having trouble with the usb_camera example. I'll open another issue if it still doesn't work after some more troubleshooting.
