My intents are documented below. The repo is not complete yet. And I have no date to provide as to when it will be complete ;-)

The repo contains C++ code to read and write ARINC-424 files in both fixed-size and XML formats.

Up to Supplement 21, the ARINC-424 file format is a pure ASCII text file of exactly 132 characters. Starting with Supplement 22, ARINC-424 files are available in XML format. The code in this repo is able to read and write files in both formats.

ARINC-424 Specification - Available on the ARINC Store

On Linux Ubuntu with Visual Studio Code and CMake.

GoogleTest:

• In /usr/include: gtest/gtest.h
• In /usr/lib: libgtest.a

Arinc424 is the main namespace; it contains functions and classes that are of general use.

Arinc424::Record contains one class per ARINC-424 record defined in chapter 4 of the Specification.

Arinc424::Type contains the ARINC-424 data types of chapter 5.

Arinc424::Enum contains all ARINC-424 enumerations found in chapter 5.

Supplement 22 to ARINC-424 introduces an XML format formalized by several XSD schemas; the files and types defining these schemas form the basis of this C++ library. Each .xsd file correspond to a pair of .h/.cpp files. And most - if not all - complex types defined in these schemas have a matching C++ class.

The C++ Data Model of this SDK closely matches the data model that is proposed by the Specification. CodeSynthesis XSD compiler is used to compile the XSDs into C++ Parser Skeletons. See the Getting Started Guide for an excellent introduction to this open-source XSD/C++ Compiler.

The library is organised in the following sets of folders.

• bin contains the SDK executables built by the sources, samples, and tests
• data contains the data files used by the samples and tests
• doc contains the SDK documentation (produced by Doxygen)
• inc contains the SDK public headers
• lib contains the SDK static libraries
• samples contains code to illustrate how to use the SDK
• src contains the source files to build the SDK static libraries and executables
• test contains the SDK Test Suite (based on the Google Test Framework)
