Major architectural refactoring to achieve 1:1 structural compatibility: 🏗️ **VC2022 Structure Replication** - Iso1EXIDocument: 1:1 replica of VC2022 iso1EXIDocument struct - DinEXIDocument: 1:1 replica of VC2022 dinEXIDocument struct - Iso2EXIDocument: 1:1 replica of VC2022 iso2EXIDocument struct - All _isUsed flags and Initialize() methods exactly matching VC2022 🔄 **VC2022 Function Porting** - ParseXmlToIso1(): Exact port of VC2022 parse_xml_to_iso1() - EncodeIso1ExiDocument(): Exact port of VC2022 encode_iso1ExiDocument() - Choice 76 (V2G_Message) encoding with identical logic - BulkChargingComplete ignore behavior preserved ⚡ **Call Sequence Alignment** - Old: EncodeV2GMessage() → direct EXI encoding - New: EncodeV2GMessage() → Iso1EXIDocument → EncodeIso1ExiDocument() - Exact VC2022 call chain: init → parse → encode → finish 🔍 **1:1 Debug Comparison Ready** - C# exiDoc.V2G_Message_isUsed ↔ VC2022 exiDoc->V2G_Message_isUsed - Identical structure enables line-by-line debugging comparison - Ready for precise 1-byte difference investigation (41 vs 42 bytes) 📁 **Project Reorganization** - Moved from csharp/ to Port/ for cleaner structure - Port/dotnet/ and Port/vc2022/ for parallel development - Complete build system and documentation updates 🎯 **Achievement**: 97.6% binary compatibility (41/42 bytes) Next: 1:1 debug session to identify exact byte difference location 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

------------------------------------------------------------------------- * fix possible memory corruption bug ------------------------------------------------------------------------- CHANGES from version 0.9.3: ------------------------------------------------------------------------- * Support for 15118-2-2016 (ISO2) started besides 15118-2-2013 (ISO1) and DIN * fix eMAID fragment encoding/decoding support * internal coding updates * bug-fixes ------------------------------------------------------------------------- CHANGES from version 0.9.2: ------------------------------------------------------------------------- * resolves XML signature interoperability issue Note: To make use of xmldsig the following defines have to be set. in "xmldsigEXIDatatypes.h" #define DEPLOY_XMLDSIG_CODEC SUPPORT_YES #define DEPLOY_XMLDSIG_CODEC_FRAGMENT SUPPORT_YES in "v2gEXIDatatypes.h" #define DEPLOY_ISO_CODEC_FRAGMENT SUPPORT_YES Otherwise the code is turned off. ------------------------------------------------------------------------- CHANGES from version 0.9.1: ------------------------------------------------------------------------- * resolves bug with name clashes w.r.t. iso and din track * fixes issue with test code for init handshake * Note: OpenV2G 0.9.2 is essentially just a bug fixed version of OpenV2G 0.9.1 ------------------------------------------------------------------------- CHANGES from version 0.9: ------------------------------------------------------------------------- * includes support for DIN and hence interoperability with OpenV2G 0.7 (needs to be switched on though by #define DEPLOY_DIN_CODEC) * fixes bugs and warnings for Visual Studio * Note: OpenV2G 0.9.1 is a superset of previous versions v2g...c/h files support ISO track din...c/h files support DIN track ------------------------------------------------------------------------- CHANGES from version 0.8: ------------------------------------------------------------------------- * large code footprint reduction which resulted in a new API (please take a look at the example in src/test folder) * datatype differences w.r.t. arrays, strings, bytes, isUsed, and enum-naming * bug-fixes * Note: OpenV2G 0.8 and 0.9 are interoperable, meaning that one can generate streams with one and decode with the other or vice-versa ------------------------------------------------------------------------- CHANGES from version 0.7: ------------------------------------------------------------------------- * adaption of V2G schema changes (reflects the ISO/IEC 15118-2 FDIS status) * bug-fixes ------------------------------------------------------------------------- CHANGES from version 0.7: ------------------------------------------------------------------------- * adaption of V2G schema changes (reflects the ISO/IEC 15118-2 FDIS status) * bug-fixes ------------------------------------------------------------------------- CHANGES from version 0.6: ------------------------------------------------------------------------- * adaption of V2G schema changes (reflects the ISO/IEC 15118-2 DIS status and DIN 70121) * reduced memory usage * EXI decoder skips schema deviations according to EXI Profile * bug-fixes ------------------------------------------------------------------------- CHANGES from version 0.5: ------------------------------------------------------------------------- * adaption of V2G schema changes * application handshake protocol implementation * asynchronised communication * reduced memory usage * changed V2GTP byte order from little endian to big endian * bug-fixes * updated AC demo interaction between EV and EVSE, and * updated DC demo interaction between EV and EVSE ------------------------------------------------------------------------- CHANGES from version 0.4: ------------------------------------------------------------------------- * adaption of V2G schema changes * V2GTP implementation (replaces the DoIP implementation) * EXI default coder for the 15118 schema (replaces the strict mode of EXI) * AC demo interaction between PEV and EVSE, and * DC demo interaction between PEV and EVSE ------------------------------------------------------------------------- CHANGES from version 0.3.1: ------------------------------------------------------------------------- * adaption of V2G schema changes * supporting of DC messages * example program showing the message sequence of AC charging and DC charging * bug-fixes ------------------------------------------------------------------------- CHANGES from version 0.3: ------------------------------------------------------------------------- * Bug-fixes * reduced memory usage * some type changes in the EXI codec and V2G service: ** struct v2gService->struct EXIService in v2g_service.h ** size_t->uint16_t in v2g_serviceClientDataTransmitter.h and doIP.h * renaming of some enumeration values in v2g_serviceDataTypes.h ------------------------------------------------------------------------- CHANGES from version 0.2.2: ------------------------------------------------------------------------- * Bug-fixes * first DoIP implementation * V2G message error handling * adaption of V2G schema changes * code optimizations ------------------------------------------------------------------------- CHANGES from version 0.2.1: ------------------------------------------------------------------------- * Bug-fixes * adaption of V2G schema changes * some code optimizations ------------------------------------------------------------------------- CHANGES from version 0.2: ------------------------------------------------------------------------- * Bug-fixes * Fixed
