On Board Computer

This repository contains all the code that will be ran on the on board computer system. The OBC is made up on 6 ESP32 S3 microcontrollers, one for each subsystem.

Within the src/ there is a folder for each subsystem:

• OBDH-TTC: Main controller, triggers in-flight events, telemetry, and on-board storage handler.
• EPS: Managed power, current and voltage sensors, and triggers power cycles.
• Instrumentation: Handles all housekeeping sensors.
• Mechanisms: Handles the fluidics and iris actuators.
• Photonics: Manages all photodiodes and LEDs for the on board cell excitation period.
• Thermals: Contains the thermal controler system (PID) and a kalman filter.

Each ESP32 is connected by a CAN Bus for bi-directional communication. The code to send/receive data over the CAN Bus is avaliable in libs/libcanbus which provides the necessary abstractions for communication.
