Dash gauge for visualizing data from a Tech Edge wideband DAQ.

Setup: create a venv and install requirements.txt

cd vanagauge && python -m venv env && source env/bin/activate && pip install -r requirements.txt

Raspbian has moved to Wayfire from X, add to ~/.config/wayfire.ini:

[autostart]
dashtaskid = $HOME/vanagauge/dashServiceStart.sh

Graceful shutdown on pin toggle:

sudo cp shutdownPin17.service /etc/systemd/system/shutdownPin17.service
sudo systemctl enable shutdownPin17.service && sudo systemctl daemon-reload && sudo systemctl start shutdownPin17.service

The lastest version of Raspbian is using Wayland instead of X. To hide the cursor:
