Core software repository for the Tennessee Valley Stellar Corporation
This repository is the principal codebase for the Tennessee Valley Stellar Corporation. We are a community-scale space agency in east Tennessee dedicated to the open development of technologies enabling the public use of space.
There are three main sections to the repository. The most active development at the moment is taking place in the hal and the electronics directories. The hal directory contains the Hardware Abstraction Layer. The electronics directory holds our PCB design work. The rest of the repository (the third section) consists of older code that is in need of…
