🚗 Example: Binary CAN Frame → Parsed Output

This project includes a minimal CAN frame deserializer that converts a raw binary buffer into a structured CanFrame object.

Input buffer (raw CAN frame)

12 34 56 78 04 AA BB CC

This represents:

• ID: 0x12345678
• DLC: 0x04
• Data bytes: AA BB CC (remaining bytes padded with 00)

---

Parsed output

{
  id: 0x12345678,
  dlc: 4,
  data: [AA, BB, CC, 00]
}

This is exactly what the parser returns internally and what the unit tests print to the terminal and CI logs.

🧪 Test Output (Local + CI)

When running tests locally or in GitHub Actions, you will see output like:

Input buffer:
12 34 56 78 04 AA BB CC

Output struct:
ID=0x12345678
DLC=4
Data=[AA BB CC 00]

🛠 How it works

The parser reads:

1. 4 bytes → 32‑bit CAN ID (big‑endian)
2. 1 byte → DLC
3. N bytes → Data payload
4. Pads remaining bytes with 0x00 to reach 8 bytes

This matches typical automotive ECU expectations.
