Meeting Notes (2020 06 09)

Demo from Chris: What he's done the past week with animations

• This experimentation was done in doughsay/rgb_matrix_simulator.
• Rewrite animations to be black boxes. They have their own way to store opaque state.
• Changed pixel tuples to modules: Key, LED, KeyWithLED
• Key positions can be floats now, opposed to the integers they used to be. This allows a full-size keyboard layout to be represented, rather than just aligned grids of keys like the Keybow.
• Animation has been renamed to Effect (math-based animations).
• Effects can accept a key_pressed function to receive these types of events and alter animations based on them.
• Discuss how to implement an effect that changes color every key press.
  • init_state and next_state should probably be called new and render, respectively.
  • render implies "do not block inside this function call (a good thing).
  • This effect can be stateless if the random color is generated at the beginning of render, because it's a fast operation.
  • On key_pressed set next_call property to 0 so that render gets scheduled immediately.
  • In addition to handling key presses, we would also want to handle key codes (i.e. AFK). We would want to know which key was pressed on which layer.
