BabyLIN SDK placement

Place the SDK's Python wrapper and platform-specific libraries here so the test framework can import and use them.

Required files

• BabyLIN_library.py
• BabyLIN library/ (directory provided by the SDK containing platform-specific binaries)
  • Windows: BabyLIN library/Windows/x64/*.dll
  • Linux x86_64: BabyLIN library/Linux/x86_64/*.so
  • Raspberry Pi (ARM): BabyLIN library/Linux/armv7/*.so (or as provided by your SDK)
• Optional: Example SDF file (e.g., Example.sdf)

Folder structure example:

vendor/
├─ BabyLIN_library.py
├─ Example.sdf
└─ BabyLIN library/
   ├─ Windows/
   │  └─ x64/
   │     ├─ BabyLIN.dll
   │     ├─ BabyLIN_FTDI.dll
   │     └─ ... (other DLLs from SDK)
   ├─ Linux/
   │  ├─ x86_64/
   │  │  └─ libBabyLIN.so
   │  └─ armv7/
   │     └─ libBabyLIN.so
   └─ ...

Notes:

• Keep the directory names and casing exactly as the SDK expects (often referenced in BabyLIN_library.py).
• Ensure your Python environment architecture matches the binaries (e.g., 64-bit Python with 64-bit DLLs).
• On Linux/RPi, you may need to set LD_LIBRARY_PATH to include the directory with the shared libraries.

Configuration

Point your config to the SDF and schedule:

interface:
  type: babylin
  channel: 0
  sdf_path: ./vendor/Example.sdf
  schedule_nr: 0

Troubleshooting

• ImportError: BabyLIN_library not found
  • Ensure vendor/BabyLIN_library.py exists or add the vendor folder to PYTHONPATH.
• DLL/SO not found
  • On Windows, ensure the DLLs are in PATH or next to BabyLIN_library.py per SDK instructions.
  • On Linux/RPi, export LD_LIBRARY_PATH to the folder with the .so files.
• Device not found
  • Check USB connection, drivers, and that no other tool holds the device open.
