- Create complete VS2022 solution with 3 projects: * V2GDecoder: Main EXI decoder with debugging support * HexToBinary: Hex string to binary utility * HexDumpToBinary: Hex dump to binary utility - Copy all source files locally for Windows compilation: * Added Windows compatibility for unistd.h, fstat, S_ISREG * Fixed VLA issues in EncoderChannel.c with macro definitions * Include all required modules: codec, iso1, iso2, din, appHandshake - Build configuration: * Support Debug/Release x86/x64 configurations * Proper include directories and preprocessor definitions * Windows-specific compiler flags (_WIN32, __STDC_NO_VLA__) - Verification: * Both test4.exi and test5.exi decode/encode perfectly * 100% binary compatibility: original ↔ XML ↔ reencoded * Ready for step-by-step debugging in Visual Studio 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
