# AS - Automotive Software

**AS** is an open-source implementation of automotive software based on **AUTOSAR 4.4**, covering BSW (Basic Software) modules, PC tools, and supporting libraries, developed independently by one author. It is free for evaluation and study purposes; commercial use requires a commercial license (see [License](#license)).

## Tools & Libraries

### Bus Simulation & Hardware Access

- **CanBusSimulator**: CAN bus simulator over IP socket.
- **LinBusSimulator**: LIN bus simulator over IP socket.
- **CanLib**: CAN library to access CAN hardware (Vector CanCaseXL, PeakCan, ZLGCAN, etc.).
- **LinLib**: LIN library to access LIN hardware (COM, USB2I2C, USB2SPI, etc.).
- **DevLib**: abstract device libraries to access any other kind of automotive devices.

### Protocol & Middleware

- **IsoTp**: LIN or CAN (CAN FD) transport layer (ISO 15765).
- **Loader**: library used for bootloader.
- **DoIPClient**: DoIP client library to access a DoIP server.
- [**VDDS**](infras/libraries/dds/vdds/): [Virtio ring buffer & shared memory based DDS](doc/EN/VirtioDDS.md).

### PC Tools

- **AsPy**: Python interface providing APIs for CAN, LIN and IsoTp, easy to be used to implement test cases.
- **asone**: Qt based GUI tool for Com/Dcm/FlashLoader, provided in both a Python version and a pure C++ version (the C++ version is recommended). It embeds a Lua engine for UICom and UIDcm, so Lua scripts can be used to control Com/UDS communication.
- **JSON Editor**: JSON schema & PyQt5 based configuration GUI tool for AS.
