Introduction
The automotive industry is undergoing an unprecedented digital transformation, with intelligence, connectivity, and electrification becoming unstoppable trends. This has led to an increasing demand for automotive diagnostic and repair tools. Traditional car scanners often have single functions and complicated operations, making it difficult to meet the complex diagnostic needs of modern vehicles. The CAR-Scanner project, based on the STM32H7 processor, provides a brand new solution for creating a powerful and user-friendly universal car scanner.
Overview of the CAR-Scanner Project
The CAR-Scanner project is based on the STM32H743XIH6U processor and uses the TouchGFX graphics library, aiming to develop a powerful, user-friendly universal car scanner. The goals of the project are:
-
• Comprehensive automotive diagnostic capabilities: Support reading and clearing fault codes, real-time data stream monitoring, and executing specific function tests.
-
-
• User-friendly interface: Provides an intuitive graphical interface via TouchGFX for easy user operation.
-
• Flexible extensibility: Modular design for easy expansion of functions and protocol support.
-
• Open-source and easy to port: The project code is open-source, facilitating developers to learn and port it to other platforms.
Core Features of the CAR-Scanner Project
1. Support for automotive diagnostic protocols
The CAR-Scanner supports various automotive diagnostic protocols, including OBD-II, CAN, J1939, etc. The project code includes the corresponding protocol parsing libraries, enabling communication with different vehicles to obtain diagnostic data.
2. Reading and clearing fault codes
The CAR-Scanner can read the fault codes stored in the vehicle and provide detailed fault code information, such as code descriptions and affected systems. Users can also clear fault codes through this tool and view the results.
3. Real-time data stream monitoring
The CAR-Scanner supports real-time monitoring of various vehicle data, such as engine speed, vehicle speed, oil temperature, water temperature, etc. This feature helps users understand the vehicle’s operating status and promptly identify potential issues.
4. Specific function tests
The CAR-Scanner can perform specific function tests, such as ABS system tests and SRS system tests. These tests can help users quickly diagnose whether specific functional modules of the vehicle are normal.
5. Graphical interface display
The CAR-Scanner uses the TouchGFX graphics library to provide users with an intuitive graphical interface. The interface includes various functional modules, such as fault code lists, data flow charts, and test result displays.
6. Open-source code
The CAR-Scanner project code is open-source, allowing developers to freely learn, modify, and port the project.
