Python

You can also interact with PiPower using Python.

PiPower5 utilizes the SPC (SunFounder Power Control Core) library to fetch data and configure parameters. The SPC library is pre-installed in the virtual environment when you set up PiPower5. To activate the virtual environment, use the following command:

source /opt/pipower5/venv/bin/activate

We provide several Python examples to demonstrate different use cases. Navigate to the examples directory to explore them:

cd ~/pipower5/examples

Here are the available scripts and their functions:

• read_all.py: Reads all data at once and processes each item individually.

• read_individual.py: Reads specific data items, showcasing examples of fetching individual data points.

• set_shutdown_percentage.py: Configures the shutdown percentage. When the battery level falls below the set threshold, PiPower 5 sends a shutdown signal to the host. Once the shutdown process is complete, it cuts power.

• shutdown_when_request.py: Demonstrates how to handle shutdown signals. For microcontroller use, remove the SDSIG jumper cap and connect the middle pin to a GPIO pin. After receiving a shutdown signal and completing a safe shutdown, pull the GPIO pin high to allow PiPower 5 to cut power.
