bi2cp: Beagle I2C Parser

bi2cp parses CSV dumps from the Beagle logic analyzer to lift the raw I2C transfers to expose PMBus semantics.

bi2cp can also test PEC bytes in transfers among other features - external dependencies are listed in requirements.txt:

pip3 install --user --requirement requirements.txt

Example Run

$ ./bi2cp --address 0x11 --pmbus 'UCD recreate beagle scan 1.csv'  | head
