I don't know the answer to your question, but I found this a very cheap and
easy way to sniff I2C:

hi,
I want to snif an I2C bus where there only a master and a slave.
I already have this device:
PN:UMFT201XA-01
based on chip: FT201X
RS:757-0073 [1]
that it is slave only.
1) Can be used as sniffer or I need an I2C master like [2]
2) Is it supported by sigrok?
thank you,
Valerio
