This Repo's Organization

Skim through the Repo Overview section, then jump to the bottom for a treasure hunt activity!

Repo Overview

1. firmware/: The main firmware for the CTS-SAT-1 OBC, which runs on the STM32-based Onboard Computer.
   • This is the most important part, by far.
2. docs/: Hand-written documentation (mostly guides) for the software components of the projects.

firmware/ Organization

The firmware/ folder contains the main firmware for the CTS-SAT-1 OBC. It is organized as follows:

• Core/Inc/ has the header files (.h files) for the firmware.
• Core/Src/ has the source files (.c files) for the firmware.
  • main.c is the entry point for the firmware. Do not edit it (much).
  • rtos_tasks/rtos_tasks.c contains the main FreeRTOS tasks (each is a while(1) loop that takes turns with the other tasks).
• For Core/Inc/ and Core/Src/:
  • Each subsystem has its own folder.
  • Each C file has an associated header file with the same name.

Treasure Hunt Activity

1. Find where the unit tests are stored.
2. Find the documentation that explains unit tests.
3. Find where the telecommand list is stored.
4. Find the documentation that explains the telecommand format, with examples.
5. Find the driver to deploy the deployable antenna. Find the associated telecommand.
