How to Be Sure Whether a Pin is Dead

Hey there,

I might have given more than 3.3V to the SDA and SCL pins in my pi (3 b+). Is there a certain way to understand whether those pins work properly or are dead?

Thanks in advance!

I’m not sure if there’s a way to measure any damage done, but if the I2C bus still works, then for all intents and purposes, it’s not [too] damaged.
