It contains demo configuration for both bootloader and application, showcasing how UDS services can be integrated and tested in different firmware contexts.
The library currently supports the following UDS (Unified Diagnostic Services) as part of its core functionality:
| Service Name | Service ID | Description |
|---|---|---|
| Diagnostic Session Control | 0x10 | Switches between diagnostic modes |
| ECU Reset | 0x11 | Resets the ECU |
| Security Access | 0x27 | Handles security unlocking |
| Tester Present | 0x3E | Keeps diagnostic session alive |
| Routine Control | 0x31 | Executes routines on the ECU |
| Write Data By Identifier | 0x2E | Writes data to specific IDs |
| Read Data By Identifier | 0x22 | Reads data to specific IDS |
| Request Download | 0x34 | Initiates data download |
| Transfer Data | 0x36 | Transfers data blocks |
| Request Transfer Exit | 0x37 | Ends data transfer session |
| Read DTC Info* | 0x19 | Read DTC info |
| Clear Diagnostic Info | 0x14 | Clear Diagnostic info |
- See all available subfunctions under library/README.md
Additional services can be integrated as needed.
The UDS implementation itself is not hardware dependent and can be adapted to various platforms. The provided examples use the Nucleo-C092RC development board, but you can port the code to other hardware as needed.
