Tr33 Control

A web interface to control effects on leds strips. It sends commands to an ESP32 board that controls the leds. The corresponding firmware for the ESP32 can be found here.

This app leverages phoenix channels to sync the state between all connected browsers, so everybody sees the same state. The dynamic forms are all rendered in the backend and pushed via a live_html channel to the clients. It is an attempt to create a dynamic web app with almost no javascript.

Installation

The main dependency is elixir. There are many ways to install it. See the elixir install instructions. You also need a version of npm installed to get the frontend assets.

There is Makefile with the most common commands.

make init

Will install all required dependencies.

Configuration

The file tr33_control/config/config.exs contains some configuration you might want to change.

• The targets contain all supported led_structures. The host of a target reprepsents one ESP32 that is reachable via network. It can be a domain or IP Address.
• The active_targets is a white list of targets that should be active in this installation.
• If not using/not having joysticks comment out the joystick lines in lib/tr33_control/application.ex or else the application will crash when running 'make console':

  #Tr33Control.Joystick,
  #Tr33Control.Joystick.Poller
  

Running the UI

make console

Should start the web interface on localhost:4000 and sync the commands to all ESP32s.
