Welcome to the Osmocom Card Operating System

Osmocom COS (or short OsmoCOS) was the idea for an experimental Card Operating System for smart cards,
specifically for those based on the ChipCity CC32RS512 microcontroller.

It never became much of a COS, but the early beginnings of a development environment for COS development.
