ares-controls 🚀

Control systems software for the Ares rocket

MOIST:

Mission Operator Interface: Switch Terminal

Usage

$> make moist-client # Build source into executable (bin/moist)
$> make moist-deploy # Copy executable into /deploy/ (requires sudo)
$> make moist-service-setup # Sets up a systemd service for moist to auto-run on a pi (requires sudo)

$> systemctl status moist.service # Check if service running
$> sudo systemctl stop moist.service # Stop running service
$> sudo systemctl start moist.service # Start service
$> sudo systemctl enable moist.service # Start service every time we boot up
$> sudo systemctl disable moist.service # Disable auto-run of service on startup

Reading Logs:

$> sudo journalctl -u moist.service

Debugging/Development:

Aside from using services, there are several ways to manually run the program. To run the deployment version, run /deploy/moist. Otherwise, run either ares-controls/bin/moist or ares-controls/moist/__main__.py

Features

• Switch board, with switches for each valve
• Ignition and ignition safety digital inputs
• MOIST Enable digital input/switch
• LED indicator for network status and arming
• Ethernet port, internal power (power bank)

Software Features

• Callback function to handle GPIO (switch) events
• TCP Client connecting to CDH controls server
  • Socket client running asynchronously, on a separate thread
• Systemd service to run script on startup

Planned

• Clean logging and debug output
• Exception handling software (restart MOIST on error)
• Built-in battery charging port
• Field debugging/visualization output
• Heartbeat between CDH and MOIST

CDH-server:

Command and Data Handling server

Usage

$> make cdhserv # Build source into executable (bin/cdhserv)
$> make cdhserv-deploy # Copy executable into /deploy/ (requires sudo)
$> make cdhserv-service-setup # Sets up a systemd service for moist to auto-run on a pi (requires sudo)

$> systemctl status cdhserv.service # Check if service running
$> sudo systemctl stop cdhserv.service # Stop running service
$> sudo systemctl start cdhserv.service # Start service
$> sudo systemctl enable cdhserv.service # Start service every time we boot up
$> sudo systemctl disable cdhserv.service # Disable auto-run of service on startup

Reading Logs:

$> sudo journalctl -u cdhserv.service

Debugging/Development:

Aside from using services, there are several ways to manually run the program. To run the deployment version, run /deploy/cdhserv. Otherwise, run either ares-controls/bin/cdhserv or ares-controls/cdh-server/__main__.py

Features

• TCP Server for receiving commands
  • Handles MCU and Maintenance commands (connect to serial device, list serial devices, etc)
• Serial Master functionality to translate and send commands to FCM/GCM
  • Supports multiple device connections with addressing, on 1+ serial buses
  • Connects to devices by physical port location, not dynamically assigned IDs

Planned

• Handle multiple concurrent connections on separate threads, test current functionality
• Exception handling software and hardware watchdog (restart CDH on error)
• Error code and TCP response standardization
• Field debugging/visualization output
• Basic maintenance commands for serial connections/listing
• Expansion of Maintenance commands (restart server, etc)
• Heartbeat between CDH and MOIST

FCM-mcu:

Flight Control Module - microcontroller unit

Features

• Receives commands over serial/TTY to turn on/off relays
  • Error checking CRC-8 to handle bad commands or corrupted payloads

Planned

• Standalone Arduino/ATMega circuitboard with FTDI usb-uart chip
• Safe modes for resetting to default states after a timeout
• Delayed commands/task scheduler
• Store relay pin mapping and address to EEPROM
  • Commands to update mapping and address over serial
