This is the minimal requirements of the CDH software to be completed for competition. For a broader look at the software architecture see CDH Software Architecture

• Supervisor

  • Initializes tasks

• Telemetry Manager

  • Generate unique filename for next batch of telemetry → for each subsystem (send command to each subsytem?)
  • Before downlink, package subsystem telemetry files into a single telemetry batch file
  • Alert comms of filename for next telemetry (send a command to Comms)

• Command Manager

  • General skeleton implemented (generic parsing framework)
  • Parse immediate command → forward immediately to relevant subsystems
  • Parse time-tagged command → add to queue of recieved commands (sorted by earliest command at front) and set RTC to earliest command
    • Save time-tagged commands to FRAM?
  • Confirm all required uplinked commands with other subsytems → and required internal commands/actions to send out (https://docs.google.com/spreadsheets/d/1XWXgp3--NHZ4XlxOyBYPS-M_LOU_ai-I6TcvotKhR1s/edit?usp=sharing)
    • Add to Command Manager

• Health Manager

  • Define what emergency modes should be automatically dealt with
  • Define what parameters should be monitored and threshold to trigger an emergency
  • Define what action should be taken in each emergency mode → what commands are sent out?
  • Define how to store state of emergency

• EPS Task

  • Complete CAN Bus Driver
  • Define what kind of specific data are we sending between CDH and EPS (see https://docs.google.com/spreadsheets/d/1XWXgp3--NHZ4XlxOyBYPS-M_LOU_ai-I6TcvotKhR1s/edit?usp=sharing)
  • Define and implement method of EPS↔CDH micro interfacing methodology
    • Do we poll EPS everytime we want data?
    • Does EPS send an interrupt and data?
  • Save telemetry to batch file provided by TM

• RTC Driver

  • Implement interface for setting up alarms
  • Implement interface for syncing clock
  • Implement interface for dealing with alarm interrupt

• File System → Reliance Edge

  • Complete SD Card Driver
  • Implement Reliance Edge FS and add interfacing functions (focus is on telemetry data only for now)

• Non-volatile Storage (interface for FRAM)

  • Complete FRAM Driver
  • Define what data specifically will be saved to the FRAM
    • Time-tagged commands?
    • Current operational mode of satellite?
    • Critical parameters (ADCS PID values, last wake up time, etc.)?
  • Devise and implement an interface for saving data
    • Do we add macros for specific addresses to store data in?
    • Do we have a more extensible and generic storage system?
  • Implement saving and reading of the aforementioned FRAM Data

• E-Fuse Driver

• Temperature Sensor Driver

• MAX9934 Current Sensor Driver
