### Write BLF Files

Source: https://pypi.org/project/vblf/0.3.0

This example shows how to create a new BLF file and write a CAN message to it. You need to import CanMessage and BlfWriter from the vblf library.

```python
from vblf.can import CanMessage
from vblf.writer import BlfWriter

# Create a new BLF file
with BlfWriter("output.blf") as writer:
    # Create a CAN message
    msg = CanMessage(...)

    # Write the message to the file
    writer.write(msg)

```

### Read BLF Files

Source: https://pypi.org/project/vblf/0.3.0

This snippet demonstrates how to open a BLF file and iterate through its objects, specifically handling CAN messages. It requires importing CanMessage, CanMessage2, and BlfReader from the vblf library.

```python
from vblf.can import CanMessage, CanMessage2
from vblf.reader import BlfReader

# Open a BLF file
with BlfReader("example.blf") as reader:
    # Iterate through all objects in the file
    for obj in reader:
        print(f"Type: {obj.header.base.object_type.name}")
        print(f"Timestamp: {obj.header.object_time_stamp}")

        # Handle CAN messages
        if isinstance(obj, (CanMessage, CanMessage2)):
            print(f"CAN ID: {obj.id}")
            print(f"Data: {obj.data.hex()}")

```
