Python library for accessing the Razer Chroma SDK

pychroma provides general-purpose access to the Razer Chroma SDK REST API for control over the LEDs of Razer devices. The work environment is easy to set up and it features a sketch and (optionally) a controller. The sketch code structure is heavily inspired from p5js.org conventions. The controller allows having multiple sketches.

Features

• Full controll over the LEDs via Chroma SDK
• Low barrier to entry for educators and practitioners

Made for everyone

• Simply use the sketch! This library is accessible and inclusive for artists, designers, educators and beginners
• Gain more access by using the controller or handling the connection and devices all by yourself
• If you want to have full control then fork this repository and edit the source code

class MySketch(Sketch):
  config_path = 'path/to/config/file.json'

Example animation code

from pychroma import Sketch

class MySketch(Sketch):
  config_path = 'path/to/config/file.json'

  def setup(self):
    self.frame_rate = 30
    self.keyboard.color_mode('hsv')
    self.hue = 0

  def update(self):
    self.hue += 1
    if self.hue == 360:
      self.stop()

  def render(self):
    self.keyboard.set_static((self.hue, 100, 100))
