MicroPython CCSDS Space Packet, Version 0.3

This is an implementation of CCSDS Space Packet) encoder and decoder for MicroPython. It also provides transport layers for routing packets between entities. Currently, only transport over UDP is implemented.

The CCSDS Space Packet Protocol was developed by the Consultative Committee for Space Data Systems (CCSDS): The Space Packet Protocol is designed to meet the requirements of space missions to efficiently transfer space application data of various types and characteristics over a network that involves a ground-to-space or space-to-space communications link (also called space link).

Getting Started

Copy the src/spacepacket directory to your MicroPython device:

cp src/spacepacket/ <micropython-device>:/spacepacket/

You can then do import spacepacketin your MicroPython scripts.

Alternatively, copy the compiled .mpy files (smaller and faster to load) to the MicroPython device:

cp build/spacepacket/ <micropython-device>:/spacepacket/

To re-build the .mpy files, run build.sh. You need to have mpy-cross installed (pip install mpy-cross)

MicroPython Compatibility

This library is compatible with MicroPython 1.20.0 and above. Key differences from the Python version:

• Uses _thread instead of threading module
• Type hints and f-strings removed for broader compatibility
