Whistler Blackcomb Flight Computer Firmware

This is a repository with the code for the UBC Rocket Whistler Blackcomb flight computer. A compiled version of it should hopefully at some point be in space.

Project Structure

This is a high level overview of the file structure we use for this project. Any folders not mentioned here are libraries/drivers that are not custom developed.

• board
  • Generated files by MCUXpresso for pin configuration
• common
  • Code that is shared between x86 and board implementations, i.e. logic code
• data
  • Misc. files used for testing or logging
• doc
  • Project documentation in markdown
• envs
  • Hardware abstraction layer that calls hardware level functionality directly
• source
  • Main program entrance point
• test
  • Unit test folder
• tools
  • Misc. tools for ease of development

Project Documentation

All documentation is currently kept in the doc/ directory. Note that although this is the firmware repository, all documentation for the wb-avionics subteam is located here for ease of finding things.

Onboarding Documents
