Yes, I will change

Okay, I will drop one example of I2C

May I know how its unused, AFAIK, Since it's an I/O expanded, it’s referenced elsewhere, so keeping it is necessary for functionality.

Since I expect resend, correct also quotes - use consistently either '
or ".

Drop this example.

Keep one complete example for i2c and one for spi. This was not in
