The open-source SpaceWire project

Overview

SpaceWire is the standard data transfer and network interface which is standardized as ECSS-E-ST-50-12C lead by the European Space Agency (ESA). RMAP is a short for Remote Memory Access Protocol which is the standardized data transfer protocol over SpaceWire (ECSS-E-ST-50-52C).

User Ruby wrapper of SpaceWire/RMAP Library

Now users can use basic SpaceWire and RMAP functionalities of the library in the Ruby scripting language. Scripting capability allows developers to quickly iterate try-and-error loops on, for example, new SpaceWire device without compiling a test program.

The SWIG wrapper is already included in the Github repository of SpaceWire RMAP Library, and existing users can pull it by executing:
