Intermediate Server

Welcome to the intermediate server repository. The intermediate server is a black-box intermediate server that sits between the SUFST car telemetry system and the back-end server to translate PDU frames to sensors.

Relevant Repositories are linked below:

Getting Started

To install the server, follow the instructions below:

1. Prerequisites

Currently, you will need the following items installed on your system in order to get the server running:

  • Git
  • Python3.9

You also need a UNIX based environment. If you're using a macOS or Linux system, you're fine. If you're using Windows, you need to either install WSL.

Note: Currently, only Python versions 3.9.x work. If you have anything higher, make sure to install a supported version.

2. Installing & Building

  1. Clone the repository using:
https://github.com/sufst/intermediate-server.git
  1. Open the terminal window and navigate to the folder where the server was cloned.

Note: On Windows, this need to be a WSL terminal.

  1. Create a new Python Virtual Environment named venv using:
python3 -m venv venv

Note: If you have multiple versions of Python3 installed, you will need to replace python3 with python3.9.

  1. Activate the Python Virtual Environment using:
source venv/bin/activate

(venv) should now appear in the LHS of your terminal.

  1. Install all dependancies using:
pip install wheel

and then

pip install -r requirements.txt

If everything installs fine, you should now be able to run the server using

python server.py

You can cancel the server anything with Control+C. To leave/exit the python venv run deactivate.

Running

Once the server is installed, you can run it anytime using the following steps.

  1. Open a terminal window and navigate to the intermediate-server folder.

Note: On Windows, this need to be a WSL terminal.

  1. Activate the Python Virtual Environment using:
source venv/bin/activate

(venv) should now appear in the LHS of your terminal.

  1. Run the python file to start the server using:
python server.py

You can cancel the server anything with Control+C. To leave/exit the python venv run deactivate.

Known Issues:

  1. Currently, the schema.json and verson.json files need to be manually updated everytime a new version of these is generated from the can-defs repo. In the future this will be automatically handled using git-submodules.
