esrom

Source code for the esrom geocache.

If you have found the source code before finding the geocache, consider it a hint :)

Setup (for future me)

• elixir 1.9.0-otp-22
• erlang 22.0.4
• nodejs 12.6.0
• Nerves
• Phoenix

dev

• Run epmd in the background so it can function as a distributed system with the pi.
• Run cd ui && mix deps.get to install Elixir dependencies.
• Run cd assets && npm install && cd .. to install npm dependencies.
• Run mix phx.server to start the server.

Building

cd ui/ && export SECRET_KEY_BASE="$(mix phx.gen.secret | tail -1)"
export MIX_ENV=prod && export MIX_TARGET=<device>
cd assets && npm install && node node_modules/webpack/bin/webpack.js --mode production
cd ../ && mix phx.digest
cd ../firmware && mix deps.get
mix firmware
mix firmware.burn # After inserting SD card

Setting morse code

To set the morse code, create a new file under firmware/config, called secrets.exs:

use Mix.Config

config :morse, :morse_message, "...---..."
