Exercise for Real-Time Operating Systems Design and Implementation 25/26

In order to use the setup you will need to configure your system in the following way:

1. Install the required system packages and configure your system accordingly
2. Run the local_setup.sh script to install and setup the development environment
3. To build the sample project, we use the provided idf.py scripts:
   1. To activate the idf.py script, run . ./esp/esp-idf/export.sh from the root of the repository
   2. To build the project, run idf.py build
   3. To flash the firmware to a connected Watchy, run idf.py flash
   4. To display serial output on your console, run idf.py monitor

If you use Linux, see the Setup Linux section below for required packages and system configurations.

If you use macOS, see the Setup macOS section below for required packages.

Setup Linux

• Make sure you have the required dependencies installed. A starting point of debian packages would be git wget flex bison gperf python3 python3-pip python3-venv cmake ninja-build ccache libffi-dev libssl-dev dfu-util libusb-1.0-0
• In order to flash the project, your user needs permissions to access the device. Consider adding your user to the dialout group: sudo usermod -a -G dialout $USER

Setup macOS

• Make sure the required dependencies are installed. If you use HomeBrew, they can be installed with: brew install cmake ninja dfu-util
• You need a Python 3 interpreter, for example, you can use the bundled Python 3.9 interpreter (on macOS Sonoma). If your bundled Python version is Python 2, install a Python 3 interpreter, for example with HomeBrew.

Tracing script and visualization

Our tracing export script and the visualization can be found under ./tracing_scripts/. For how to use it refer to the readme under ./tracing_scripts/README.md
