Quick Start (Local Development)

1. Create and activate virtual environment

python3 -m venv kivy_venv
source kivy_venv/bin/activate
pip install --upgrade pip
python -m pip install "kivy[full]"

2. Build and run sensor writer (Linux target)

This step is usually not necessary as these processes should be running as systemd services. You can probably check with systemctl status uc26_sensor.service. Otherwise,

cd uc26_sensor_reader
g++ -O2 -std=c++17 write_shm.cpp -lpigpiod_if2 -lrt -pthread -o shm_writer
sudo pigpiod
./shm_writer

3. Run dashboard on LCD display session

export DISPLAY=:0
python uisensor.py
