Using Python with the Kubos SDK¶
The Kubos SDK Vagrant box comes with a Python interperter and all the modules needed to develop a basic hardware service or mission application. Services can be tested locally in the Vagrant box up until the point that they need hardware interaction.
The SDK comes with support for both Python2.7 and Python3.7. However, only Python3.7 is available on OBCs running Kubos Linux.
Transferring to Target¶
The ISIS-OBC does not currently support Python due to size constraints
There are currently two ways to add Python scripts and libraries to a system running Kubos Linux:
Add a new Python package to a custom Kubos Linux build
- Fork and clone kubos-linux-build and add additional Python packages to the package/python directory
- You can see our current system packages and how they are structured here.
- See the custom Kubos Linux docs for more information on building Kubos Linux.
Add individual Python files on the fly by transferring them to an attached hardware target
Python project files can be transferred to the target OBC via a supported file transfer method.
Binaries may be transferred to any location on the target board, however, they should be copied to /home/system/usr/bin if you would like them to be automatically accessible via the system PATH.
Running on Target¶
The following steps will allow you to run Python3.7 files which have been flashed to a Linux target:
- Make sure you can communicate with your OBC.
- Transfer your python script using a supported file transfer method.
- Navigate to the destination folder of the transfer.
- Your Python files should be here. You can now run them with
