ASN.1 PUS-C Types Library is an ASN.1 implementation of the PUS-C ECSS standard using ACN encoding.

See ECSS-E-ST-70-41C for details about the PUS-C standard.

See ASN1SCC for details about ACN encoding.

Library was developed by N7 Space and funded by European Space Agency (ESA) and is distributed under GPL v3.0 license.

Requirements

ASN.1 components are ment to work with any ASN.1 based tool, but project itself is prepared to be included as “ASN.1 Components Library” in Qt Creator’s plugin asn1scc.IDE. ACN encoding is supported by ASN1SCC - ASN.1/ACN compiler for embedded systems (distributed with asn1scc.IDE).

Library includes CCSDS utility functions, which were implemented in C in C99 standard.

Installation for asn1scc.IDE

Install desired version of Qt Creator and Plugin
Download library release
Unpack library package
If you want plugin to automatically detect library, copy it to specific directory:
- To be visible by every plugin user (assuming QtCreator was installed under default path):
  - Linux: /opt/Qt/Tools/QtCreator/share/qtcreator/asn1acn/libs
  - Windows: C:\Qt\Tools\QtCreator\share\qtcreator\asn1acn\libs
- To be visible only by current user:
  - Linux: ~/.config/QtProject/qtcreator/asn1acn/libs
  - Windows: %APPDATA%\QtProject\qtcreator\asn1acn\libs

Development

Library itself is an asn1scc.IDE project and should be developed in it.
Library metadata follows JSON schema defined by asn1scc.IDE.
Library and it’s metadata is validated using Bash script sanity-check.sh, it requires Python and ASN1SCC to run.
