v1.1.0

🚀 Key Improvements

• writeData Overhaul: The writeData function has been fully refactored. It now accepts a dataBytes array and automatically handles header generation and checksum calculation.
• Simplified Arguments: Both writeData and writeRawData no longer require the array length as a parameter; the library now handles this internally.
• clearEcho Reliability: Completely refactored to use timing-based waiting. It now accept a length parameter and clears a specific data length, significantly increasing communication reliability.

✨ New Features

Protocol & Communication

• 5 Baud Read: Added support for the 5 Baud 7O1 Read function .
• Checksum Flexibility:
  • Added 2 new checksum calculation methods.
  • Added a checksumType parameter to writeRawData selection.
• Data Verification: Added a new method to compare received data against expected values.

Configuration Setters

New setter functions allow for more granular control over the protocol parameters:

• Checksum: Added setChecksumType.
• Custom Header: Added setISO14230Header and setISO9141Header.
• Init Address: Added setInitAddress.
• Connection Status: Added setConnectionStatus.
• Data Length Formatting: Added setLengthMode to configure whether the data length is included in the header or sent as an extra byte following the header.

📚 Documentation & Examples

• Schematics: Added more schematic diagrams for K-Line circuits.
• New Examples:
  • Sniffer: Added a K-Line sniffer code example for traffic analysis.
  • Car Specific: Added example codes containing specific manufacturer commands.
  • Board Checks: Added compatibility checks for different board architectures in examples.

🛠 Internal Improvements & CI

• Debug Messages: Refined and cleaned up debug outputs for better clarity.
• CI/CD: Added a GitHub Actions workflow (.yml) to automate compilation checks and ensure build stability.
