I’m looking for the lowdown on the i2c pull-up specifications for CE boards. The documentation is a bit unclear in this regard;
“It is recommended that a 2K2R pullup is provided on each I2C signal, dependent on any relevant drive/pullup specifications of the SoC.”
I’m trying to understand if this means that as a developer of a mezzanine that uses i2c, I can ASSUME that the i2c will be driven by proper pull-up, or if there is some chance that some board might not.
Do I leave pull-up resistors off of the i2c on the mezzanine? Or do I add them? If I add them, how big?
