Misc. experiments with what is being sold as a $15 dev kit, but in fact is a recycled product called the Recon Sentinel.
Right now most of the information can be found in the journal. As things move along I'll work on adding more to this file.
Armbian comes with python3, but not all the dependencies these scripts require. You could install these directly, but it's safer to use a venv instead.
From the directory you cloned this repository into...
sudo apt install python3-pip
sudo apt install python3-venv
sudo apt install python3-dev
python3 -m venv /path/to/your/venvs/recon-sentinel-hacking
source /path/to/your/venvs/recon-sentinel-hacking/bin/activate
pip install wheel
pip install -r requirements.txt
By default normal users are not granted access to the i2c device files used to communicate with the LCD, therefore sudo is required to run these scripts. This is complicated slightly by the virtual environment setup, so the command to run the hello-lcd.py script looks like this:
sudo /path/to/your/venvs/recon-sentinel-hacking/bin/python ./hello-lcd.py
