plasmalights 2.0.2

Plasma: LED Sequencing
Plasma is an LED/Light sequencing suite written to harmonise a variety of LED strand/board types and interfaces into a standard API for write-once-run-anyway lighting code.
Plasma also includes plasmad, a system daemon for sequencing light strips using PNG images to provide animation frames.




Compatible Products
Plasma was originally written to provide an easy way to sequence lights and swap out patterns for the Pimoroni Plasma kit.

Installing
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/.
Manual install:
sudo pip3 install plasmalights

Using Plasma Daemon
To install the Plasma daemon you should clone this repository, navigate to the "daemon" directory and run the installer:
git clone https://github.com/pimoroni/plasma
cd plasma/daemon
sudo ./install


Note: If you're using Picade Player X you should edit daemon/etc/systemd/system/plasma.service and change the output device option from -o GPIO:15:14 to -o SERIAL:/dev/ttyACM0. If you're using Unicorn HAT or pHAT you should use -o WS281X:WS2812:18:0.
If you're using GPIO on a Picade HAT you can adjust the pins accordingly using -o GPIO:<data>:<clock> where data and clock are valid BCM pins. If you're using the old Plasma/Hack header you may need to swap from -o GPIO:15:14 to -o GPIO:14:15 depending on how your connections are wired.

The Plasma daemon installer 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 commands:

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

Development:
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
