This repository contains a library for K-Line communication implemented in C. K-Line communication is commonly used in automotive diagnostics and is supported by various electronic control units (ECUs).

The kline.c file provides the implementation of K-Line communication functionality, including initialization, sending messages, and handling responses. It utilizes UART communication via the usbd_cdc_if.h and main.h files. The kline.h header file defines the necessary structures and function prototypes.

• kline.c: Contains the implementation of K-Line communication functions.
• kline.h: Header file with structure definitions and function prototypes.
• main.h: Header file for main configurations.
• usbd_cdc_if.h: Header file for USB communication interface.

• STM32 HAL Library
• STM32 USB Library

To use this library, include kline.h in your project and ensure that the STM32 HAL and USB libraries are properly configured. Initialize the UART communication and call the appropriate functions from kline.c to send and receive messages over K-Line.

• calcChecksum: Calculates the checksum of a given data array.
• filterData: Filters the received data based on a specified length.
• initEcu: Initializes the ECU for communication.
• pingECU: Sends a wakeup message to the ECU.
• UART_TURN_OFF / UART_TURN_ON: Functions to turn off/on UART communication.
• resetGpio: Resets the GPIO configuration for UART communication.
• main_loop: Main loop for handling K-Line communication.
