Is it possible that the pinout of the Quick Start Guide for the FRDM-KL82Z board has the pins PTB0/1 and PTB10/11 mixed up?
I looked at the KL82 sub family documentation and tried to use I2C0 on PTB0/1. When I didn't get a signal, I checked the pins PTB10/11 and there was the signal. Vice versa, using I2C1 I got the signal on PTB0/1 instead. On the board these are Pins 10/12 and 18/20 respectively.
It is not a problem as such, but confusing.
