I am using 715 on both sides, supply is 5.3v 2A switching and a 100uF electrolitic, It looks smooth
I have pullups of 560ohm on both sides and both lines.
I think the clock line looks weird, amplitude varies, I attached a capture.
I have 2 channels same setup one was working one wasn`t after 1 day.
on short distance it works flawless, but connected together when the long line gets stuck it blocks the local one.
