    Hello. I’m currently trying to get a sensor working using I2c protocol, and I have a question about the 2.2 kohm resistors on the SDA and SCL lines. Are those resistances automatically enabled, or is there a line of code that would enable them? Otherwise, if the pull-up resistors are automatically enabled on the Mayfly, is there any way to disable those resistances? Any help would be greatly appreciated! Thank you in advance for your time!
