STeC

Software

Get started

  1. Clone the code repository (including submodules):
    git clone --recursive https://gitlab.ethz.ch/tec/public/stec/stec-code
  2. Follow the instructions in the Flora Wiki to compile and flash the code using the STMCubeIDE.
  3. Clone the script repository to schedule tests and inspect the data:
    git clone https://gitlab.ethz.ch/tec/public/stec/stec-scripts

If you would like to inspect the scripts without installing anything, you can also run them directly online or use a static version where we ran the script for you.

Software Development

STM32CubeIDE

  • The project has been created and edited using the STM32CubeIDE (itself a combination of former Atollic TrueStudio and STM32CubeMX)
    • The IDE is based on eclipse
    • The main config file of the IDE project is stored in the .cproject file
    • The architecture configurations (GPIOs etc.) are stored in the *.ioc file.

Hardware

More detailed schematics and layouts are available on request.

FAQ

What does 'STeC' mean?

The name STeC is an abbreviation of "Spatial and Temporal Correlation", thereby stressing the novel design paradigm that the protocol is leveraging. Furthermore, the protocol has been designed by TEC, the Computer Engineering Group at ETH Zurich.

Where can I get the sensor data?

All data from our outdoor deployment is available through the PermaSense GSN website. The easiest way to access and download it is through our scripts (e.g. /scripts/analysis/data_management/data_manager.py). Data from our deployments on the premises of ETH Zurich and on FlockLab 2 are available on request.

Can I see STeC in action?

Unfortunately, we had to stop our outdoor deployment running at Dirruhorn, Switzerland on 09.03.2022 for organisational reasons. Until then, it was possible to use the monitoring scripts (e.g. /scripts/analysis/notebooks/stec_monitoring_7d.ipynb) to get the most up-to-date version or run the script directly online (or use a static version where we ran the script for you). Raw sensor data can always be inspected in real-time and downloaded using the PermaSense GSN website.
