Simulated Pixels in Webassembly

Connection Manager

• Move connection between webapp and controllers to new class
• Standardized RequestResponse

Simulated Pixels in Webrowser

• Run pixel simulation in browser instead of webapp server
• Uses emsdk to compile c++ controller code into wasm
  • Uses same animation code as actual controllers so easier to test

Logging

• Using logging library
• Multiple levels and colors for different types of messages
• Save log to file

Sequencer and Scheduler

Add Sequencer and Scheduler

• Prewrite sequences of animations
• Schedule sequences to run

Add new Animations

• randomCycle: cycle between random colors
• reverser: reverse animation direction and/or static pixels

Pixel Display

Add Pixel Simulation and Display

• Option for webapp to simulate pixel animation functions
  • -s command line option to enable
  • changed some makefile targets to use simulation
• Use SocketIO to send generated pixels to display on website
• GRB option
• Add helper functions to linter globals
• Label option for version info
• Bug Fixes:
  • Reverse arg from webpage now boolean type (was string which caused it to always equal true)
  • Pulse animation can have 0 spacing

Rewrote entire project

Description:

This project uses a webapp and either ESP8266s or raspberrypis to controll ws2812 or ws2815 LEDs.
The webapp is hosted on a Flask webserver. It recieves commands from the website it hosts and uses
its config information to send these commands to the correct controller. The webapp also uses
SocketIO to communicate with the website clients which is used to update connected status and
make changes to brightness broadcasted to all.
