Interactive Simulations and Visualizations for the Lecture in Digital Communication Systems
Project description
DCS Interactive
Interactive Simulations and Visualizations for the Lecture in Digital Communication Systems at the Otto-von-Guericke-University Magdeburg.
Installation
Prerequisites:
- Python 3.10+ must be installed on the system
For Windows systems, ensure that Python is available in the PATH variable.
For installation, execute in a terminal (the example shows a Bash terminal on Linux):
# 1. Create a virtual environment
python -m venv dcs_venv
# 2. Activate the virtual environment
source ./dcs_venv/bin/activate
# 3. Installation
pip install dcs-interactive
# 4. Deactivate the virtual environment
deactivate
Run the Application
# 1. Activate the virtual environment
source ./dcs_venv/bin/activate
# 2. Run it
dcs-interactive
# 3. Deactivate the virtual environment
deactivate
Troubleshooting
Application does not start
Perhaps, an incorrect value has been set in an input field. Unfortunately, the application does not validate the values before saving, but before loading it from the permanent storage. This leads to an error. This bug is going to be fixed in future versions.
Solution: Edit the permanent configuration storage or delete it. The storage can be found:
- on Linux systems:
$HOME/.config/dcs_interactive/config.toml
- on Windows:
C:\Users\<username>\AppData\Roaming\Philipp Le\dcs_interactive\config.toml
