This project is the original µOS++, written in the mid 2000s, initially for AVR-8 and later ported to AVR-32.
It was used in a seismograph, some SDI-12 sensors sold by Metrilog GmbH and the flight data recorder and acquisition modules installed in the Remos G-3 ultralight owned by Aviation Instruments SRL.
It was followed by µOS++ SE (second edition), in 2013, which was more modular and included an experimental configuration mechanism inspired by eCos CDL.
The project is now archived, and preserved for historical reasons.
