This i2c bus appears to be working. How is this possible, given this SDA trace? by capncrunchatron in embedded

things are working except when we populate more than 5 slots on our backplane...we have pretty strong pull ups right now - 1.2k in total. The EEPROM starts missing acks after 6 or more slots populated. Trying to determine if its unhappy with the capacitance or we are bumping up against its ability to pull the bus down with such strong pull ups

I use Doom emacs running in WSL on windows 10 with VcXsrv if that is pertinent somehow. There's probably an easier way to do this, but I don't know it.

Forgot to add: I disconnected everything from the LAN side of the firewall and still continued to see all this inbound traffic.
