Python library for driving Pimoroni Plasma!
Eight super-bright RGB LED indicators, ideal for adding visual notifications to your Raspberry Pi on their own or on a pHAT stacking header.
Full install (recommended):
We’ve created an easy installation script that will install all pre-requisites and get your Plasma Arcade Button Lights up and running with minimal efforts. To run it, fire up Terminal which you’ll find in Menu -> Accessories -> Terminal on your Raspberry Pi desktop, as illustrated below:
In the new terminal window type the command exactly as it appears below (check for typos) and follow the on-screen instructions:
curl https://get.pimoroni.com/plasma | bash
If you choose to download examples you’ll find them in /home/pi/Pimoroni/plasma/.
Library install for Python 3:
sudo apt-get install python3-plasmalights
sudo pip3 install plasmalights
Library install for Python 2:
sudo apt-get install python-plasmalights
sudo pip2 install plasmalights
Plasma installs two programs onto your Raspberry Pi. plasma itself and a tool called plasmactl you can use to install and switch lighting effects. Plasma runs as a service on your system.
- plasmactl 255 0 0 - Set Plasma lights to R, G, B colour. Red in this case.
- plasmactl <pattern> - Set Plasma lights to pattern image
- plasmactl fps <fps> - Change plasma effect framerate (default is 30, lower FPS = less CPU)
- plasmactl --list - List all available patterns
- sudo plasmactl --install <pattern> - Install a new pattern, where <pattern> is the filename of a 24bit PNG image file
If you want to contribute, or like living on the edge of your seat by having the latest code, you should clone this repository, cd to the library directory, and run:
sudo python3 setup.py install
(or sudo python setup.py install whichever your primary Python environment may be)
