# 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`:

```sh
pip3 install --user --requirement requirements.txt
```

## Example Run

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