SDEC - Sun Devil Rocketry

Most of SDR's work is open source. See this project for yourself.

About

Capabilities

SDEC is our primary way of communicating with SDR's embedded computers. It is a command line interface written in Python that provides a number of commands to interact with our hardware over USB. Below is a non-exhaustive list of some of our most important commands.

Command	Subcommand	Description
Connect	[none]	Manages a serial connection with the attached board.
Comports	[none]	List the serial ports on your PC to identify where the hardware is connected.
Preset	Upload	Parse a preset data file, serialize the contents, and pass it to the flight computer to be used in flight. Computes a checksum for data validity.
Preset	Download	Download the presets that are currently on the flight computer, deserialize the contents, and write it to a file.
Preset	Verify	Tell the flight computer to recompute the checksum over the presets, compare it to the original, and send the result.
Flash	Erase	Clear the entirety of flash.
Flash	Extract	Download the contents of flash memory, including preset data (if applicable) and sensor data.
Sensor	Poll	Check specific sensor values and log them to console continuously.
Sensor	Dump	Output all sensor values to console continuously. Used extensively in the Flight Dashboard, which is in development by the software team.

My Contributions

The development of SDEC is tightly coupled with the flight computer's firmware. If we add a sensor, we need to update SDEC at the same time to recognize the difference in the schema. Because of this, even though the firmware is my main focus, I've done a fair amount of work on SDEC.
