So that begs the question, how do we calculate the resistor size?
The manual says 4.7K resistors, but I suspect that is an 'average'.

Ah! Thanks Dave!
So, what happens when you have more than 1 I2C device?
Do you have only one pair of pull-ups on the mcu, or one pair on each device?

Open-collector VS bipolar lines on I2C devices
Hi,
The manual mentions that the Clock and Data lines for I2C devices can be made either open-collector or bipolar. Open-collector requires a 4.7K pull-up resistor on the Clock and Data lines,...
